1 1.1 jruoho ---------------------------------------- 2 1.1.1.3.2.1 yamt 18 December 2013. Summary of changes for version 20131218: 3 1.1.1.3.2.1 yamt 4 1.1.1.3.2.1 yamt Global note: The ACPI 5.0A specification was released this month. There 5 1.1.1.3.2.1 yamt are no changes needed for ACPICA since this release of ACPI is an 6 1.1.1.3.2.1 yamt errata/clarification release. The specification is available at 7 1.1.1.3.2.1 yamt acpi.info. 8 1.1.1.3.2.1 yamt 9 1.1.1.3.2.1 yamt 10 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 11 1.1.1.3.2.1 yamt 12 1.1.1.3.2.1 yamt Added validation of the XSDT root table if it is present. Some older 13 1.1.1.3.2.1 yamt platforms contain an XSDT that is ill-formed or otherwise invalid (such 14 1.1.1.3.2.1 yamt as containing some or all entries that are NULL pointers). This change 15 1.1.1.3.2.1 yamt adds a new function to validate the XSDT before actually using it. If the 16 1.1.1.3.2.1 yamt XSDT is found to be invalid, ACPICA will now automatically fall back to 17 1.1.1.3.2.1 yamt using the RSDT instead. Original implementation by Zhao Yakui. Ported to 18 1.1.1.3.2.1 yamt ACPICA and enhanced by Lv Zheng and Bob Moore. 19 1.1.1.3.2.1 yamt 20 1.1.1.3.2.1 yamt Added a runtime option to ignore the XSDT and force the use of the RSDT. 21 1.1.1.3.2.1 yamt This change adds a runtime option that will force ACPICA to use the RSDT 22 1.1.1.3.2.1 yamt instead of the XSDT (AcpiGbl_DoNotUseXsdt). Although the ACPI spec 23 1.1.1.3.2.1 yamt requires that an XSDT be used instead of the RSDT, the XSDT has been 24 1.1.1.3.2.1 yamt found to be corrupt or ill-formed on some machines. Lv Zheng. 25 1.1.1.3.2.1 yamt 26 1.1.1.3.2.1 yamt Added a runtime option to favor 32-bit FADT register addresses over the 27 1.1.1.3.2.1 yamt 64-bit addresses. This change adds an option to favor 32-bit FADT 28 1.1.1.3.2.1 yamt addresses when there is a conflict between the 32-bit and 64-bit versions 29 1.1.1.3.2.1 yamt of the same register. The default behavior is to use the 64-bit version 30 1.1.1.3.2.1 yamt in accordance with the ACPI specification. This can now be overridden via 31 1.1.1.3.2.1 yamt the AcpiGbl_Use32BitFadtAddresses flag. ACPICA BZ 885. Lv Zheng. 32 1.1.1.3.2.1 yamt 33 1.1.1.3.2.1 yamt During the change above, the internal "Convert FADT" and "Verify FADT" 34 1.1.1.3.2.1 yamt functions have been merged to simplify the code, making it easier to 35 1.1.1.3.2.1 yamt understand and maintain. ACPICA BZ 933. 36 1.1.1.3.2.1 yamt 37 1.1.1.3.2.1 yamt Improve exception reporting and handling for GPE block installation. 38 1.1.1.3.2.1 yamt Return an actual status from AcpiEvGetGpeXruptBlock and don't clobber the 39 1.1.1.3.2.1 yamt status when exiting AcpiEvInstallGpeBlock. ACPICA BZ 1019. 40 1.1.1.3.2.1 yamt 41 1.1.1.3.2.1 yamt Added helper macros to extract bus/segment numbers from the HEST table. 42 1.1.1.3.2.1 yamt This change adds two macros to extract the encoded bus and segment 43 1.1.1.3.2.1 yamt numbers from the HEST Bus field - ACPI_HEST_BUS and ACPI_HEST_SEGMENT. 44 1.1.1.3.2.1 yamt Betty Dall <betty.dall (a] hp.com> 45 1.1.1.3.2.1 yamt 46 1.1.1.3.2.1 yamt Removed the unused ACPI_FREE_BUFFER macro. This macro is no longer used 47 1.1.1.3.2.1 yamt by ACPICA. It is not a public macro, so it should have no effect on 48 1.1.1.3.2.1 yamt existing OSV code. Lv Zheng. 49 1.1.1.3.2.1 yamt 50 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 51 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 52 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 53 1.1.1.3.2.1 yamt has a much larger code and data size. 54 1.1.1.3.2.1 yamt 55 1.1.1.3.2.1 yamt Current Release: 56 1.1.1.3.2.1 yamt Non-Debug Version: 96.1K Code, 27.0K Data, 123.1K Total 57 1.1.1.3.2.1 yamt Debug Version: 185.6K Code, 77.3K Data, 262.9K Total 58 1.1.1.3.2.1 yamt Previous Release: 59 1.1.1.3.2.1 yamt Non-Debug Version: 95.9K Code, 27.0K Data, 122.9K Total 60 1.1.1.3.2.1 yamt Debug Version: 185.1K Code, 77.2K Data, 262.3K Total 61 1.1.1.3.2.1 yamt 62 1.1.1.3.2.1 yamt 63 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 64 1.1.1.3.2.1 yamt 65 1.1.1.3.2.1 yamt Disassembler: Improved pathname support for emitted External() 66 1.1.1.3.2.1 yamt statements. This change adds full pathname support for external names 67 1.1.1.3.2.1 yamt that have been resolved internally by the inclusion of additional ACPI 68 1.1.1.3.2.1 yamt tables (via the iASL -e option). Without this change, the disassembler 69 1.1.1.3.2.1 yamt can emit multiple externals for the same object, or it become confused 70 1.1.1.3.2.1 yamt when the Scope() operator is used on an external object. Overall, greatly 71 1.1.1.3.2.1 yamt improves the ability to actually recompile the emitted ASL code when 72 1.1.1.3.2.1 yamt objects a referenced across multiple ACPI tables. Reported by Michael 73 1.1.1.3.2.1 yamt Tsirkin (mst (a] redhat.com). 74 1.1.1.3.2.1 yamt 75 1.1.1.3.2.1 yamt Tests/ASLTS: Updated functional control suite to execute with no errors. 76 1.1.1.3.2.1 yamt David Box. Fixed several errors related to the testing of the interpreter 77 1.1.1.3.2.1 yamt slack mode. Lv Zheng. 78 1.1.1.3.2.1 yamt 79 1.1.1.3.2.1 yamt iASL: Added support to detect names that are declared within a control 80 1.1.1.3.2.1 yamt method, but are unused (these are temporary names that are only valid 81 1.1.1.3.2.1 yamt during the time the method is executing). A remark is issued for these 82 1.1.1.3.2.1 yamt cases. ACPICA BZ 1022. 83 1.1.1.3.2.1 yamt 84 1.1.1.3.2.1 yamt iASL: Added full support for the DBG2 table. Adds full disassembler, 85 1.1.1.3.2.1 yamt table compiler, and template generator support for the DBG2 table (Debug 86 1.1.1.3.2.1 yamt Port 2 table). 87 1.1.1.3.2.1 yamt 88 1.1.1.3.2.1 yamt iASL: Added full support for the PCCT table, update the table definition. 89 1.1.1.3.2.1 yamt Updates the PCCT table definition in the actbl3.h header and adds table 90 1.1.1.3.2.1 yamt compiler and template generator support. 91 1.1.1.3.2.1 yamt 92 1.1.1.3.2.1 yamt iASL: Added an option to emit only error messages (no warnings/remarks). 93 1.1.1.3.2.1 yamt The -ve option will enable only error messages, warnings and remarks are 94 1.1.1.3.2.1 yamt suppressed. This can simplify debugging when only the errors are 95 1.1.1.3.2.1 yamt important, such as when an ACPI table is disassembled and there are many 96 1.1.1.3.2.1 yamt warnings and remarks -- but only the actual errors are of real interest. 97 1.1.1.3.2.1 yamt 98 1.1.1.3.2.1 yamt Example ACPICA code (source/tools/examples): Updated the example code so 99 1.1.1.3.2.1 yamt that it builds to an actual working program, not just example code. Added 100 1.1.1.3.2.1 yamt ACPI tables and execution of an example control method in the DSDT. Added 101 1.1.1.3.2.1 yamt makefile support for Unix generation. 102 1.1.1.3.2.1 yamt 103 1.1.1.3.2.1 yamt ---------------------------------------- 104 1.1.1.3.2.1 yamt 15 November 2013. Summary of changes for version 20131115: 105 1.1.1.3.2.1 yamt 106 1.1.1.3.2.1 yamt This release is available at https://acpica.org/downloads 107 1.1.1.3.2.1 yamt 108 1.1.1.3.2.1 yamt 109 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 110 1.1.1.3.2.1 yamt 111 1.1.1.3.2.1 yamt Resource Manager: Fixed loop termination for the "get AML length" 112 1.1.1.3.2.1 yamt function. The loop previously had an error termination on a NULL resource 113 1.1.1.3.2.1 yamt pointer, which can never happen since the loop simply increments a valid 114 1.1.1.3.2.1 yamt resource pointer. This fix changes the loop to terminate with an error on 115 1.1.1.3.2.1 yamt an invalid end-of-buffer condition. The problem can be seen as an 116 1.1.1.3.2.1 yamt infinite loop by callers to AcpiSetCurrentResources with an invalid or 117 1.1.1.3.2.1 yamt corrupted resource descriptor, or a resource descriptor that is missing 118 1.1.1.3.2.1 yamt an END_TAG descriptor. Reported by Dan Carpenter 119 1.1.1.3.2.1 yamt <dan.carpenter (a] oracle.com>. Lv Zheng, Bob Moore. 120 1.1.1.3.2.1 yamt 121 1.1.1.3.2.1 yamt Table unload and ACPICA termination: Delete all attached data objects 122 1.1.1.3.2.1 yamt during namespace node deletion. This fix updates namespace node deletion 123 1.1.1.3.2.1 yamt to delete the entire list of attached objects (attached via 124 1.1.1.3.2.1 yamt AcpiAttachObject) instead of just one of the attached items. ACPICA BZ 125 1.1.1.3.2.1 yamt 1024. Tomasz Nowicki (tomasz.nowicki (a] linaro.org). 126 1.1.1.3.2.1 yamt 127 1.1.1.3.2.1 yamt ACPICA termination: Added support to delete all objects attached to the 128 1.1.1.3.2.1 yamt root namespace node. This fix deletes any and all objects that have been 129 1.1.1.3.2.1 yamt attached to the root node via AcpiAttachData. Previously, none of these 130 1.1.1.3.2.1 yamt objects were deleted. Reported by Tomasz Nowicki. ACPICA BZ 1026. 131 1.1.1.3.2.1 yamt 132 1.1.1.3.2.1 yamt Debug output: Do not emit the function nesting level for the in-kernel 133 1.1.1.3.2.1 yamt build. The nesting level is really only useful during a single-thread 134 1.1.1.3.2.1 yamt execution. Therefore, only enable this output for the AcpiExec utility. 135 1.1.1.3.2.1 yamt Also, only emit the thread ID when executing under AcpiExec (Context 136 1.1.1.3.2.1 yamt switches are still always detected and a message is emitted). ACPICA BZ 137 1.1.1.3.2.1 yamt 972. 138 1.1.1.3.2.1 yamt 139 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 140 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 141 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 142 1.1.1.3.2.1 yamt has a much larger code and data size. 143 1.1.1.3.2.1 yamt 144 1.1.1.3.2.1 yamt Current Release: 145 1.1.1.3.2.1 yamt Non-Debug Version: 95.9K Code, 27.0K Data, 122.9K Total 146 1.1.1.3.2.1 yamt Debug Version: 185.1K Code, 77.2K Data, 262.3K Total 147 1.1.1.3.2.1 yamt Previous Release: 148 1.1.1.3.2.1 yamt Non-Debug Version: 95.8K Code, 27.0K Data, 122.8K Total 149 1.1.1.3.2.1 yamt Debug Version: 185.2K Code, 77.2K Data, 262.4K Total 150 1.1.1.3.2.1 yamt 151 1.1.1.3.2.1 yamt 152 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 153 1.1.1.3.2.1 yamt 154 1.1.1.3.2.1 yamt AcpiExec/Unix-OSL: Use <termios.h> instead of <termio.h>. This is the 155 1.1.1.3.2.1 yamt correct portable POSIX header for terminal control functions. 156 1.1.1.3.2.1 yamt 157 1.1.1.3.2.1 yamt Disassembler: Fixed control method invocation issues related to the use 158 1.1.1.3.2.1 yamt of the CondRefOf() operator. The problem is seen in the disassembly where 159 1.1.1.3.2.1 yamt control method invocations may not be disassembled properly if the 160 1.1.1.3.2.1 yamt control method name has been used previously as an argument to CondRefOf. 161 1.1.1.3.2.1 yamt The solution is to not attempt to emit an external declaration for the 162 1.1.1.3.2.1 yamt CondRefOf target (it is not necessary in the first place). This prevents 163 1.1.1.3.2.1 yamt disassembler object type confusion. ACPICA BZ 988. 164 1.1.1.3.2.1 yamt 165 1.1.1.3.2.1 yamt Unix Makefiles: Added an option to disable compiler optimizations and the 166 1.1.1.3.2.1 yamt _FORTIFY_SOURCE flag. Some older compilers have problems compiling ACPICA 167 1.1.1.3.2.1 yamt with optimizations (reportedly, gcc 4.4 for example). This change adds a 168 1.1.1.3.2.1 yamt command line option for make (NOOPT) that disables all compiler 169 1.1.1.3.2.1 yamt optimizations and the _FORTIFY_SOURCE compiler flag. The default 170 1.1.1.3.2.1 yamt optimization is -O2 with the _FORTIFY_SOURCE flag specified. ACPICA BZ 171 1.1.1.3.2.1 yamt 1034. Lv Zheng, Bob Moore. 172 1.1.1.3.2.1 yamt 173 1.1.1.3.2.1 yamt Tests/ASLTS: Added options to specify individual test cases and modes. 174 1.1.1.3.2.1 yamt This allows testers running aslts.sh to optionally specify individual 175 1.1.1.3.2.1 yamt test modes and test cases. Also added an option to disable the forced 176 1.1.1.3.2.1 yamt generation of the ACPICA tools from source if desired. Lv Zheng. 177 1.1.1.3.2.1 yamt 178 1.1.1.3.2.1 yamt ---------------------------------------- 179 1.1.1.3.2.1 yamt 27 September 2013. Summary of changes for version 20130927: 180 1.1.1.3.2.1 yamt 181 1.1.1.3.2.1 yamt This release is available at https://acpica.org/downloads 182 1.1.1.3.2.1 yamt 183 1.1.1.3.2.1 yamt 184 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 185 1.1.1.3.2.1 yamt 186 1.1.1.3.2.1 yamt Fixed a problem with store operations to reference objects. This change 187 1.1.1.3.2.1 yamt fixes a problem where a Store operation to an ArgX object that contained 188 1.1.1.3.2.1 yamt a 189 1.1.1.3.2.1 yamt reference to a field object did not complete the automatic dereference 190 1.1.1.3.2.1 yamt and 191 1.1.1.3.2.1 yamt then write to the actual field object. Instead, the object type of the 192 1.1.1.3.2.1 yamt field object was inadvertently changed to match the type of the source 193 1.1.1.3.2.1 yamt operand. The new behavior will actually write to the field object (buffer 194 1.1.1.3.2.1 yamt field or field unit), thus matching the correct ACPI-defined behavior. 195 1.1.1.3.2.1 yamt 196 1.1.1.3.2.1 yamt Implemented support to allow the host to redefine individual OSL 197 1.1.1.3.2.1 yamt prototypes. This change enables the host to redefine OSL prototypes found 198 1.1.1.3.2.1 yamt in the acpiosxf.h file. This allows the host to implement OSL interfaces 199 1.1.1.3.2.1 yamt with a macro or inlined function. Further, it allows the host to add any 200 1.1.1.3.2.1 yamt additional required modifiers such as __iomem, __init, __exit, etc., as 201 1.1.1.3.2.1 yamt necessary on a per-interface basis. Enables maximum flexibility for the 202 1.1.1.3.2.1 yamt OSL interfaces. Lv Zheng. 203 1.1.1.3.2.1 yamt 204 1.1.1.3.2.1 yamt Hardcoded the access width for the FADT-defined reset register. The ACPI 205 1.1.1.3.2.1 yamt specification requires the reset register width to be 8 bits. ACPICA now 206 1.1.1.3.2.1 yamt hardcodes the width to 8 and ignores the FADT width value. This provides 207 1.1.1.3.2.1 yamt compatibility with other ACPI implementations that have allowed BIOS code 208 1.1.1.3.2.1 yamt with bad register width values to go unnoticed. Matthew Garett, Bob 209 1.1.1.3.2.1 yamt Moore, 210 1.1.1.3.2.1 yamt Lv Zheng. 211 1.1.1.3.2.1 yamt 212 1.1.1.3.2.1 yamt Changed the position/use of the ACPI_PRINTF_LIKE macro. This macro is 213 1.1.1.3.2.1 yamt used 214 1.1.1.3.2.1 yamt in the OSL header (acpiosxf). The change modifies the position of this 215 1.1.1.3.2.1 yamt macro in each instance where it is used (AcpiDebugPrint, etc.) to avoid 216 1.1.1.3.2.1 yamt build issues if the OSL defines the implementation of the interface to be 217 1.1.1.3.2.1 yamt an inline stub function. Lv Zheng. 218 1.1.1.3.2.1 yamt 219 1.1.1.3.2.1 yamt Deployed a new macro ACPI_EXPORT_SYMBOL_INIT for the main ACPICA 220 1.1.1.3.2.1 yamt initialization interfaces. This change adds a new macro for the main init 221 1.1.1.3.2.1 yamt and terminate external interfaces in order to support hosts that require 222 1.1.1.3.2.1 yamt additional or different processing for these functions. Changed from 223 1.1.1.3.2.1 yamt ACPI_EXPORT_SYMBOL to ACPI_EXPORT_SYMBOL_INIT for these functions. Lv 224 1.1.1.3.2.1 yamt Zheng, Bob Moore. 225 1.1.1.3.2.1 yamt 226 1.1.1.3.2.1 yamt Cleaned up the memory allocation macros for configurability. In the 227 1.1.1.3.2.1 yamt common 228 1.1.1.3.2.1 yamt case, the ACPI_ALLOCATE and related macros now resolve directly to their 229 1.1.1.3.2.1 yamt respective AcpiOs* OSL interfaces. Two options: 230 1.1.1.3.2.1 yamt 1) The ACPI_ALLOCATE_ZEROED macro uses a simple local implementation by 231 1.1.1.3.2.1 yamt default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define. 232 1.1.1.3.2.1 yamt 2) For AcpiExec (and for debugging), the macros can optionally be 233 1.1.1.3.2.1 yamt resolved 234 1.1.1.3.2.1 yamt to the local ACPICA interfaces that track each allocation (local tracking 235 1.1.1.3.2.1 yamt is used to immediately detect memory leaks). 236 1.1.1.3.2.1 yamt Lv Zheng. 237 1.1.1.3.2.1 yamt 238 1.1.1.3.2.1 yamt Simplified the configuration for ACPI_REDUCED_HARDWARE. Allows the kernel 239 1.1.1.3.2.1 yamt to predefine this macro to either TRUE or FALSE during the system build. 240 1.1.1.3.2.1 yamt 241 1.1.1.3.2.1 yamt Replaced __FUNCTION_ with __func__ in the gcc-specific header. 242 1.1.1.3.2.1 yamt 243 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 244 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 245 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 246 1.1.1.3.2.1 yamt has a much larger code and data size. 247 1.1.1.3.2.1 yamt 248 1.1.1.3.2.1 yamt Current Release: 249 1.1.1.3.2.1 yamt Non-Debug Version: 95.8K Code, 27.0K Data, 122.8K Total 250 1.1.1.3.2.1 yamt Debug Version: 185.2K Code, 77.2K Data, 262.4K Total 251 1.1.1.3.2.1 yamt Previous Release: 252 1.1.1.3.2.1 yamt Non-Debug Version: 96.7K Code, 27.1K Data, 123.9K Total 253 1.1.1.3.2.1 yamt Debug Version: 184.4K Code, 76.8K Data, 261.2K Total 254 1.1.1.3.2.1 yamt 255 1.1.1.3.2.1 yamt 256 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 257 1.1.1.3.2.1 yamt 258 1.1.1.3.2.1 yamt iASL: Implemented wildcard support for the -e option. This simplifies use 259 1.1.1.3.2.1 yamt when there are many SSDTs that must be included to resolve external 260 1.1.1.3.2.1 yamt method 261 1.1.1.3.2.1 yamt declarations. ACPICA BZ 1041. Example: 262 1.1.1.3.2.1 yamt iasl -e ssdt*.dat -d dsdt.dat 263 1.1.1.3.2.1 yamt 264 1.1.1.3.2.1 yamt AcpiExec: Add history/line-editing for Unix/Linux systems. This change 265 1.1.1.3.2.1 yamt adds a portable module that implements full history and limited line 266 1.1.1.3.2.1 yamt editing for Unix and Linux systems. It does not use readline() due to 267 1.1.1.3.2.1 yamt portability issues. Instead it uses the POSIX termio interface to put the 268 1.1.1.3.2.1 yamt terminal in raw input mode so that the various special keys can be 269 1.1.1.3.2.1 yamt trapped 270 1.1.1.3.2.1 yamt (such as up/down-arrow for history support and left/right-arrow for line 271 1.1.1.3.2.1 yamt editing). Uses the existing debugger history mechanism. ACPICA BZ 1036. 272 1.1.1.3.2.1 yamt 273 1.1.1.3.2.1 yamt AcpiXtract: Add support to handle (ignore) "empty" lines containing only 274 1.1.1.3.2.1 yamt one or more spaces. This provides compatible with early or different 275 1.1.1.3.2.1 yamt versions of the AcpiDump utility. ACPICA BZ 1044. 276 1.1.1.3.2.1 yamt 277 1.1.1.3.2.1 yamt AcpiDump: Do not ignore tables that contain only an ACPI table header. 278 1.1.1.3.2.1 yamt Apparently, some BIOSs create SSDTs that contain an ACPI table header but 279 1.1.1.3.2.1 yamt no other data. This change adds support to dump these tables. Any tables 280 1.1.1.3.2.1 yamt shorter than the length of an ACPI table header remain in error (an error 281 1.1.1.3.2.1 yamt message is emitted). Reported by Yi Li. 282 1.1.1.3.2.1 yamt 283 1.1.1.3.2.1 yamt Debugger: Echo actual command along with the "unknown command" message. 284 1.1.1.3.2.1 yamt 285 1.1.1.3.2.1 yamt ---------------------------------------- 286 1.1.1.3.2.1 yamt 23 August 2013. Summary of changes for version 20130823: 287 1.1.1.3.2.1 yamt 288 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 289 1.1.1.3.2.1 yamt 290 1.1.1.3.2.1 yamt Implemented support for host-installed System Control Interrupt (SCI) 291 1.1.1.3.2.1 yamt handlers. Certain ACPI functionality requires the host to handle raw 292 1.1.1.3.2.1 yamt SCIs. For example, the "SCI Doorbell" that is defined for memory power 293 1.1.1.3.2.1 yamt state support requires the host device driver to handle SCIs to examine 294 1.1.1.3.2.1 yamt if the doorbell has been activated. Multiple SCI handlers can be 295 1.1.1.3.2.1 yamt installed to allow for future expansion. New external interfaces are 296 1.1.1.3.2.1 yamt AcpiInstallSciHandler, AcpiRemoveSciHandler; see the ACPICA reference for 297 1.1.1.3.2.1 yamt details. Lv Zheng, Bob Moore. ACPICA BZ 1032. 298 1.1.1.3.2.1 yamt 299 1.1.1.3.2.1 yamt Operation region support: Never locally free the handler "context" 300 1.1.1.3.2.1 yamt pointer. This change removes some dangerous code that attempts to free 301 1.1.1.3.2.1 yamt the handler context pointer in some (rare) circumstances. The owner of 302 1.1.1.3.2.1 yamt the handler owns this pointer and the ACPICA code should never touch it. 303 1.1.1.3.2.1 yamt Although not seen to be an issue in any kernel, it did show up as a 304 1.1.1.3.2.1 yamt problem (fault) under AcpiExec. Also, set the internal storage field for 305 1.1.1.3.2.1 yamt the context pointer to zero when the region is deactivated, simply for 306 1.1.1.3.2.1 yamt sanity. David Box. ACPICA BZ 1039. 307 1.1.1.3.2.1 yamt 308 1.1.1.3.2.1 yamt AcpiRead: On error, do not modify the return value target location. If an 309 1.1.1.3.2.1 yamt error happens in the middle of a split 32/32 64-bit I/O operation, do not 310 1.1.1.3.2.1 yamt modify the target of the return value pointer. Makes the code consistent 311 1.1.1.3.2.1 yamt with the rest of ACPICA. Bjorn Helgaas. 312 1.1.1.3.2.1 yamt 313 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 314 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 315 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 316 1.1.1.3.2.1 yamt has a much larger code and data size. 317 1.1.1.3.2.1 yamt 318 1.1.1.3.2.1 yamt Current Release: 319 1.1.1.3.2.1 yamt Non-Debug Version: 96.7K Code, 27.1K Data, 123.9K Total 320 1.1.1.3.2.1 yamt Debug Version: 184.4K Code, 76.8K Data, 261.2K Total 321 1.1.1.3.2.1 yamt Previous Release: 322 1.1.1.3.2.1 yamt Non-Debug Version: 96.2K Code, 27.1K Data, 123.3K Total 323 1.1.1.3.2.1 yamt Debug Version: 185.4K Code, 77.1K Data, 262.5K Total 324 1.1.1.3.2.1 yamt 325 1.1.1.3.2.1 yamt 326 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 327 1.1.1.3.2.1 yamt 328 1.1.1.3.2.1 yamt AcpiDump: Implemented several new features and fixed some problems: 329 1.1.1.3.2.1 yamt 1) Added support to dump the RSDP, RSDT, and XSDT tables. 330 1.1.1.3.2.1 yamt 2) Added support for multiple table instances (SSDT, UEFI). 331 1.1.1.3.2.1 yamt 3) Added option to dump "customized" (overridden) tables (-c). 332 1.1.1.3.2.1 yamt 4) Fixed a problem where some table filenames were improperly 333 1.1.1.3.2.1 yamt constructed. 334 1.1.1.3.2.1 yamt 5) Improved some error messages, removed some unnecessary messages. 335 1.1.1.3.2.1 yamt 336 1.1.1.3.2.1 yamt iASL: Implemented additional support for disassembly of ACPI tables that 337 1.1.1.3.2.1 yamt contain invocations of external control methods. The -fe<file> option 338 1.1.1.3.2.1 yamt allows the import of a file that specifies the external methods along 339 1.1.1.3.2.1 yamt with the required number of arguments for each -- allowing for the 340 1.1.1.3.2.1 yamt correct disassembly of the table. This is a workaround for a limitation 341 1.1.1.3.2.1 yamt of AML code where the disassembler often cannot determine the number of 342 1.1.1.3.2.1 yamt arguments required for an external control method and generates incorrect 343 1.1.1.3.2.1 yamt ASL code. See the iASL reference for details. ACPICA BZ 1030. 344 1.1.1.3.2.1 yamt 345 1.1.1.3.2.1 yamt Debugger: Implemented a new command (paths) that displays the full 346 1.1.1.3.2.1 yamt pathnames (namepaths) and object types of all objects in the namespace. 347 1.1.1.3.2.1 yamt This is an alternative to the namespace command. 348 1.1.1.3.2.1 yamt 349 1.1.1.3.2.1 yamt Debugger: Implemented a new command (sci) that invokes the SCI dispatch 350 1.1.1.3.2.1 yamt mechanism and any installed handlers. 351 1.1.1.3.2.1 yamt 352 1.1.1.3.2.1 yamt iASL: Fixed a possible segfault for "too many parent prefixes" condition. 353 1.1.1.3.2.1 yamt This can occur if there are too many parent prefixes in a namepath (for 354 1.1.1.3.2.1 yamt example, ^^^^^^PCI0.ECRD). ACPICA BZ 1035. 355 1.1.1.3.2.1 yamt 356 1.1.1.3.2.1 yamt Application OSLs: Set the return value for the PCI read functions. These 357 1.1.1.3.2.1 yamt functions simply return AE_OK, but should set the return value to zero 358 1.1.1.3.2.1 yamt also. This change implements this. ACPICA BZ 1038. 359 1.1.1.3.2.1 yamt 360 1.1.1.3.2.1 yamt Debugger: Prevent possible command line buffer overflow. Increase the 361 1.1.1.3.2.1 yamt size of a couple of the debugger line buffers, and ensure that overflow 362 1.1.1.3.2.1 yamt cannot happen. ACPICA BZ 1037. 363 1.1.1.3.2.1 yamt 364 1.1.1.3.2.1 yamt iASL: Changed to abort immediately on serious errors during the parsing 365 1.1.1.3.2.1 yamt phase. Due to the nature of ASL, there is no point in attempting to 366 1.1.1.3.2.1 yamt compile these types of errors, and they typically end up causing a 367 1.1.1.3.2.1 yamt cascade of hundreds of errors which obscure the original problem. 368 1.1.1.3.2.1 yamt 369 1.1.1.3.2.1 yamt ---------------------------------------- 370 1.1.1.3.2.1 yamt 25 July 2013. Summary of changes for version 20130725: 371 1.1.1.3.2.1 yamt 372 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 373 1.1.1.3.2.1 yamt 374 1.1.1.3.2.1 yamt Fixed a problem with the DerefOf operator where references to FieldUnits 375 1.1.1.3.2.1 yamt and BufferFields incorrectly returned the parent object, not the actual 376 1.1.1.3.2.1 yamt value of the object. After this change, a dereference of a FieldUnit 377 1.1.1.3.2.1 yamt reference results in a read operation on the field to get the value, and 378 1.1.1.3.2.1 yamt likewise, the appropriate BufferField value is extracted from the target 379 1.1.1.3.2.1 yamt buffer. 380 1.1.1.3.2.1 yamt 381 1.1.1.3.2.1 yamt Fixed a problem where the _WAK method could cause a fault under these 382 1.1.1.3.2.1 yamt circumstances: 1) Interpreter slack mode was not enabled, and 2) the _WAK 383 1.1.1.3.2.1 yamt method returned no value. The problem is rarely seen because most kernels 384 1.1.1.3.2.1 yamt run ACPICA in slack mode. 385 1.1.1.3.2.1 yamt 386 1.1.1.3.2.1 yamt For the DerefOf operator, a fatal error now results if an attempt is made 387 1.1.1.3.2.1 yamt to dereference a reference (created by the Index operator) to a NULL 388 1.1.1.3.2.1 yamt package element. Provides compatibility with other ACPI implementations, 389 1.1.1.3.2.1 yamt and this behavior will be added to a future version of the ACPI 390 1.1.1.3.2.1 yamt specification. 391 1.1.1.3.2.1 yamt 392 1.1.1.3.2.1 yamt The ACPI Power Management Timer (defined in the FADT) is now optional. 393 1.1.1.3.2.1 yamt This provides compatibility with other ACPI implementations and will 394 1.1.1.3.2.1 yamt appear in the next version of the ACPI specification. If there is no PM 395 1.1.1.3.2.1 yamt Timer on the platform, AcpiGetTimer returns AE_SUPPORT. An address of 396 1.1.1.3.2.1 yamt zero in the FADT indicates no PM timer. 397 1.1.1.3.2.1 yamt 398 1.1.1.3.2.1 yamt Implemented a new interface for _OSI support, AcpiUpdateInterfaces. This 399 1.1.1.3.2.1 yamt allows the host to globally enable/disable all vendor strings, all 400 1.1.1.3.2.1 yamt feature strings, or both. Intended to be primarily used for debugging 401 1.1.1.3.2.1 yamt purposes only. Lv Zheng. 402 1.1.1.3.2.1 yamt 403 1.1.1.3.2.1 yamt Expose the collected _OSI data to the host via a global variable. This 404 1.1.1.3.2.1 yamt data tracks the highest level vendor ID that has been invoked by the BIOS 405 1.1.1.3.2.1 yamt so that the host (and potentially ACPICA itself) can change behaviors 406 1.1.1.3.2.1 yamt based upon the age of the BIOS. 407 1.1.1.3.2.1 yamt 408 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 409 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 410 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 411 1.1.1.3.2.1 yamt has a much larger code and data size. 412 1.1.1.3.2.1 yamt 413 1.1.1.3.2.1 yamt Current Release: 414 1.1.1.3.2.1 yamt Non-Debug Version: 96.2K Code, 27.1K Data, 123.3K Total 415 1.1.1.3.2.1 yamt Debug Version: 184.4K Code, 76.8K Data, 261.2K Total 416 1.1.1.3.2.1 yamt Previous Release: 417 1.1.1.3.2.1 yamt Non-Debug Version: 95.9K Code, 26.9K Data, 122.8K Total 418 1.1.1.3.2.1 yamt Debug Version: 184.1K Code, 76.7K Data, 260.8K Total 419 1.1.1.3.2.1 yamt 420 1.1.1.3.2.1 yamt 421 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 422 1.1.1.3.2.1 yamt 423 1.1.1.3.2.1 yamt iASL: Created the following enhancements for the -so option (create 424 1.1.1.3.2.1 yamt offset table): 425 1.1.1.3.2.1 yamt 1)Add offsets for the last nameseg in each namepath for every supported 426 1.1.1.3.2.1 yamt object type 427 1.1.1.3.2.1 yamt 2)Add support for Processor, Device, Thermal Zone, and Scope objects 428 1.1.1.3.2.1 yamt 3)Add the actual AML opcode for the parent object of every supported 429 1.1.1.3.2.1 yamt object type 430 1.1.1.3.2.1 yamt 4)Add support for the ZERO/ONE/ONES AML opcodes for integer objects 431 1.1.1.3.2.1 yamt 432 1.1.1.3.2.1 yamt Disassembler: Emit all unresolved external symbols in a single block. 433 1.1.1.3.2.1 yamt These are external references to control methods that could not be 434 1.1.1.3.2.1 yamt resolved, and thus, the disassembler had to make a guess at the number of 435 1.1.1.3.2.1 yamt arguments to parse. 436 1.1.1.3.2.1 yamt 437 1.1.1.3.2.1 yamt iASL: The argument to the -T option (create table template) is now 438 1.1.1.3.2.1 yamt optional. If not specified, the default table is a DSDT, typically the 439 1.1.1.3.2.1 yamt most common case. 440 1.1.1.3.2.1 yamt 441 1.1.1.3.2.1 yamt ---------------------------------------- 442 1.1.1.3.2.1 yamt 26 June 2013. Summary of changes for version 20130626: 443 1.1.1.3.2.1 yamt 444 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 445 1.1.1.3.2.1 yamt 446 1.1.1.3.2.1 yamt Fixed an issue with runtime repair of the _CST object. Null or invalid 447 1.1.1.3.2.1 yamt elements were not always removed properly. Lv Zheng. 448 1.1.1.3.2.1 yamt 449 1.1.1.3.2.1 yamt Removed an arbitrary restriction of 256 GPEs per GPE block (such as the 450 1.1.1.3.2.1 yamt FADT-defined GPE0 and GPE1). For GPE0, GPE1, and each GPE Block Device, 451 1.1.1.3.2.1 yamt the maximum number of GPEs is 1016. Use of multiple GPE block devices 452 1.1.1.3.2.1 yamt makes the system-wide number of GPEs essentially unlimited. 453 1.1.1.3.2.1 yamt 454 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 455 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 456 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 457 1.1.1.3.2.1 yamt has a much larger code and data size. 458 1.1.1.3.2.1 yamt 459 1.1.1.3.2.1 yamt Current Release: 460 1.1.1.3.2.1 yamt Non-Debug Version: 95.9K Code, 26.9K Data, 122.8K Total 461 1.1.1.3.2.1 yamt Debug Version: 184.1K Code, 76.7K Data, 260.8K Total 462 1.1.1.3.2.1 yamt Previous Release: 463 1.1.1.3.2.1 yamt Non-Debug Version: 96.0K Code, 27.0K Data, 123.0K Total 464 1.1.1.3.2.1 yamt Debug Version: 184.1K Code, 76.8K Data, 260.9K Total 465 1.1.1.3.2.1 yamt 466 1.1.1.3.2.1 yamt 467 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 468 1.1.1.3.2.1 yamt 469 1.1.1.3.2.1 yamt Portable AcpiDump: Implemented full support for the Linux and FreeBSD 470 1.1.1.3.2.1 yamt hosts. Now supports Linux, FreeBSD, and Windows. 471 1.1.1.3.2.1 yamt 472 1.1.1.3.2.1 yamt Disassembler: Added some missing types for the HEST and EINJ tables: "Set 473 1.1.1.3.2.1 yamt Error Type With Address", "CMCI", "MCE", and "Flush Cacheline". 474 1.1.1.3.2.1 yamt 475 1.1.1.3.2.1 yamt iASL/Preprocessor: Implemented full support for nested 476 1.1.1.3.2.1 yamt #if/#else/#elif/#endif blocks. Allows arbitrary depth of nested blocks. 477 1.1.1.3.2.1 yamt 478 1.1.1.3.2.1 yamt Disassembler: Expanded maximum output string length to 64K. Was 256 bytes 479 1.1.1.3.2.1 yamt max. The original purpose of this constraint was to limit the amount of 480 1.1.1.3.2.1 yamt debug output. However, the string function in question (UtPrintString) is 481 1.1.1.3.2.1 yamt now used for the disassembler also, where 256 bytes is insufficient. 482 1.1.1.3.2.1 yamt Reported by RehabMan@GitHub. 483 1.1.1.3.2.1 yamt 484 1.1.1.3.2.1 yamt iASL/DataTables: Fixed some problems and issues with compilation of DMAR 485 1.1.1.3.2.1 yamt tables. ACPICA BZ 999. Lv Zheng. 486 1.1.1.3.2.1 yamt 487 1.1.1.3.2.1 yamt iASL: Fixed a couple of error exit issues that could result in a "Could 488 1.1.1.3.2.1 yamt not delete <file>" message during ASL compilation. 489 1.1.1.3.2.1 yamt 490 1.1.1.3.2.1 yamt AcpiDump: Allow "FADT" and "MADT" as valid table signatures, even though 491 1.1.1.3.2.1 yamt the actual signatures for these tables are "FACP" and "APIC", 492 1.1.1.3.2.1 yamt respectively. 493 1.1.1.3.2.1 yamt 494 1.1.1.3.2.1 yamt AcpiDump: Added support for multiple UEFI tables. Only SSDT and UEFI 495 1.1.1.3.2.1 yamt tables are allowed to have multiple instances. 496 1.1.1.3.2.1 yamt 497 1.1.1.3.2.1 yamt ---------------------------------------- 498 1.1.1.3.2.1 yamt 17 May 2013. Summary of changes for version 20130517: 499 1.1.1.3.2.1 yamt 500 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 501 1.1.1.3.2.1 yamt 502 1.1.1.3.2.1 yamt Fixed a regression introduced in version 20130328 for _INI methods. This 503 1.1.1.3.2.1 yamt change fixes a problem introduced in 20130328 where _INI methods are no 504 1.1.1.3.2.1 yamt longer executed properly because of a memory block that was not 505 1.1.1.3.2.1 yamt initialized correctly. ACPICA BZ 1016.

Do not use these registers (even if populated) unless the HW- 511 1.1.1.3.2.1 yamt reduced bit is set in the FADT (as per the ACPI specification). ACPICA BZ 512 1.1.1.3.2.1 yamt 1020. Lv Zheng. 513 1.1.1.3.2.1 yamt 514 1.1.1.3.2.1 yamt Implemented return value repair code for _CST predefined objects: Sort 515 1.1.1.3.2.1 yamt the 516 1.1.1.3.2.1 yamt list and detect/remove invalid entries. ACPICA BZ 890. Lv Zheng. 517 1.1.1.3.2.1 yamt 518 1.1.1.3.2.1 yamt Implemented a debug-only option to disable loading of SSDTs from the 519 1.1.1.3.2.1 yamt RSDT/XSDT during ACPICA initialization. This can be useful for debugging 520 1.1.1.3.2.1 yamt ACPI problems on some machines. Set AcpiGbl_DisableSsdtTableLoad in 521 1.1.1.3.2.1 yamt acglobal.h - ACPICA BZ 1005. Lv Zheng. 522 1.1.1.3.2.1 yamt 523 1.1.1.3.2.1 yamt Fixed some issues in the ACPICA initialization and termination code: 524 1.1.1.3.2.1 yamt Tomasz Nowicki <tomasz.nowicki (a] linaro.org> 525 1.1.1.3.2.1 yamt 1) Clear events initialized flag upon event component termination. ACPICA 526 1.1.1.3.2.1 yamt BZ 1013. 527 1.1.1.3.2.1 yamt 2) Fixed a possible memory leak in GPE init error path. ACPICA BZ 1018. 528 1.1.1.3.2.1 yamt 3) Delete global lock pending lock during termination. ACPICA BZ 1012. 529 1.1.1.3.2.1 yamt 4) Clear debug buffer global on termination to prevent possible multiple 530 1.1.1.3.2.1 yamt delete. ACPICA BZ 1010. 531 1.1.1.3.2.1 yamt 532 1.1.1.3.2.1 yamt Standardized all switch() blocks across the entire source base. After 533 1.1.1.3.2.1 yamt many 534 1.1.1.3.2.1 yamt years, different formatting for switch() had crept in. This change makes 535 1.1.1.3.2.1 yamt the formatting of every switch block identical. ACPICA BZ 997.

Chao Guan. 546 1.1.1.3.2.1 yamt 3) Add build support for Apple Mac OS X. Liang Qi. 547 1.1.1.3.2.1 yamt 548 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 549 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 550 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 551 1.1.1.3.2.1 yamt has a much larger code and data size. 552 1.1.1.3.2.1 yamt 553 1.1.1.3.2.1 yamt Current Release: 554 1.1.1.3.2.1 yamt Non-Debug Version: 96.0K Code, 27.0K Data, 123.0K Total 555 1.1.1.3.2.1 yamt Debug Version: 184.1K Code, 76.8K Data, 260.9K Total 556 1.1.1.3.2.1 yamt Previous Release: 557 1.1.1.3.2.1 yamt Non-Debug Version: 95.6K Code, 26.8K Data, 122.4K Total 558 1.1.1.3.2.1 yamt Debug Version: 183.5K Code, 76.6K Data, 260.1K Total 559 1.1.1.3.2.1 yamt 560 1.1.1.3.2.1 yamt 561 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 562 1.1.1.3.2.1 yamt 563 1.1.1.3.2.1 yamt New utility: Implemented an easily portable version of the acpidump 564 1.1.1.3.2.1 yamt utility to extract ACPI tables from the system (or a file) in an ASCII 565 1.1.1.3.2.1 yamt hex 566 1.1.1.3.2.1 yamt dump format. The top-level code implements the various command line 567 1.1.1.3.2.1 yamt options, file I/O, and table dump routines. To port to a new host, only 568 1.1.1.3.2.1 yamt three functions need to be implemented to get tables -- since this 569 1.1.1.3.2.1 yamt functionality is OS-dependent. See the tools/acpidump/apmain.c module and 570 1.1.1.3.2.1 yamt the ACPICA reference for porting instructions. ACPICA BZ 859. Notes: 571 1.1.1.3.2.1 yamt 1) The Windows version obtains the ACPI tables from the Registry. 572 1.1.1.3.2.1 yamt 2) The Linux version is under development. 573 1.1.1.3.2.1 yamt 3) Other hosts - If an OS-dependent module is submitted, it will be 574 1.1.1.3.2.1 yamt distributed with ACPICA. 575 1.1.1.3.2.1 yamt 576 1.1.1.3.2.1 yamt iASL: Fixed a regression for -D preprocessor option (define symbol). A 577 1.1.1.3.2.1 yamt restructuring/change to the initialization sequence caused this option to 578 1.1.1.3.2.1 yamt no longer work properly. 579 1.1.1.3.2.1 yamt 580 1.1.1.3.2.1 yamt iASL: Implemented a mechanism to disable specific warnings and remarks. 581 1.1.1.3.2.1 yamt Adds a new command line option, "-vw <messageid> as well as "#pragma 582 1.1.1.3.2.1 yamt disable <messageid>". ACPICA BZ 989. Chao Guan, Bob Moore. 583 1.1.1.3.2.1 yamt 584 1.1.1.3.2.1 yamt iASL: Fix for too-strict package object validation. The package object 585 1.1.1.3.2.1 yamt validation for return values from the predefined names is a bit too 586 1.1.1.3.2.1 yamt strict, it does not allow names references within the package (which will 587 1.1.1.3.2.1 yamt be resolved at runtime.) These types of references cannot be validated at 588 1.1.1.3.2.1 yamt compile time. This change ignores named references within package objects 589 1.1.1.3.2.1 yamt for names that return or define static packages. 590 1.1.1.3.2.1 yamt 591 1.1.1.3.2.1 yamt Debugger: Fixed the 80-character command line limitation for the History 592 1.1.1.3.2.1 yamt command. Now allows lines of arbitrary length. ACPICA BZ 1000. Chao Guan. 593 1.1.1.3.2.1 yamt 594 1.1.1.3.2.1 yamt iASL: Added control method and package support for the -so option 595 1.1.1.3.2.1 yamt (generates AML offset table for BIOS support.) 596 1.1.1.3.2.1 yamt 597 1.1.1.3.2.1 yamt iASL: issue a remark if a non-serialized method creates named objects. If 598 1.1.1.3.2.1 yamt a thread blocks within the method for any reason, and another thread 599 1.1.1.3.2.1 yamt enters the method, the method will fail because an attempt will be made 600 1.1.1.3.2.1 yamt to 601 1.1.1.3.2.1 yamt create the same (named) object twice. In this case, issue a remark that 602 1.1.1.3.2.1 yamt the method should be marked serialized. NOTE: may become a warning later. 603 1.1.1.3.2.1 yamt ACPICA BZ 909. 604 1.1.1.3.2.1 yamt 605 1.1.1.3.2.1 yamt ---------------------------------------- 606 1.1.1.3.2.1 yamt 18 April 2013. Summary of changes for version 20130418: 607 1.1.1.3.2.1 yamt 608 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 609 1.1.1.3.2.1 yamt 610 1.1.1.3.2.1 yamt Fixed a possible buffer overrun during some rare but specific field unit 611 1.1.1.3.2.1 yamt read operations. This overrun can only happen if the DSDT version is 1 -- 612 1.1.1.3.2.1 yamt meaning that all AML integers are 32 bits -- and the field length is 613 1.1.1.3.2.1 yamt between 33 and 55 bits long. During the read, an internal buffer object 614 1.1.1.3.2.1 yamt is 615 1.1.1.3.2.1 yamt created for the field unit because the field is larger than an integer 616 1.1.1.3.2.1 yamt (32 617 1.1.1.3.2.1 yamt bits). However, in this case, the buffer will be incorrectly written 618 1.1.1.3.2.1 yamt beyond the end because the buffer length is less than the internal 619 1.1.1.3.2.1 yamt minimum 620 1.1.1.3.2.1 yamt of 64 bits (8 bytes) long. The buffer will be either 5, 6, or 7 bytes 621 1.1.1.3.2.1 yamt long, but a full 8 bytes will be written. 622 1.1.1.3.2.1 yamt 623 1.1.1.3.2.1 yamt Updated the Embedded Controller "orphan" _REG method support. This refers 624 1.1.1.3.2.1 yamt to _REG methods under the EC device that have no corresponding operation 625 1.1.1.3.2.1 yamt region. This is allowed by the ACPI specification. This update removes a 626 1.1.1.3.2.1 yamt dependency on the existence an ECDT table. It will execute an orphan _REG 627 1.1.1.3.2.1 yamt method as long as the operation region handler for the EC is installed at 628 1.1.1.3.2.1 yamt the EC device node and not the namespace root. Rui Zhang (original 629 1.1.1.3.2.1 yamt update), Bob Moore (update/integrate). 630 1.1.1.3.2.1 yamt 631 1.1.1.3.2.1 yamt Implemented run-time argument typechecking for all predefined ACPI names 632 1.1.1.3.2.1 yamt (_STA, _BIF, etc.) This change performs object typechecking on all 633 1.1.1.3.2.1 yamt incoming arguments for all predefined names executed via 634 1.1.1.3.2.1 yamt AcpiEvaluateObject. This ensures that ACPI-related device drivers are 635 1.1.1.3.2.1 yamt passing correct object types as well as the correct number of arguments 636 1.1.1.3.2.1 yamt (therefore identifying any issues immediately). Also, the ASL/namespace 637 1.1.1.3.2.1 yamt definition of the predefined name is checked against the ACPI 638 1.1.1.3.2.1 yamt specification for the proper argument count. Adds one new file, 639 1.1.1.3.2.1 yamt nsarguments.c 640 1.1.1.3.2.1 yamt 641 1.1.1.3.2.1 yamt Changed an exception code for the ASL UnLoad() operator. Changed the 642 1.1.1.3.2.1 yamt exception code for the case where the input DdbHandle is invalid, from 643 1.1.1.3.2.1 yamt AE_BAD_PARAMETER to the more appropriate AE_AML_OPERAND_TYPE. 644 1.1.1.3.2.1 yamt 645 1.1.1.3.2.1 yamt Unix/Linux makefiles: Removed the use of the -O2 optimization flag in the 646 1.1.1.3.2.1 yamt global makefile. The use of this flag causes compiler errors on earlier 647 1.1.1.3.2.1 yamt versions of GCC, so it has been removed for compatibility. 648 1.1.1.3.2.1 yamt 649 1.1.1.3.2.1 yamt Miscellaneous cleanup: 650 1.1.1.3.2.1 yamt 1) Removed some unused/obsolete macros 651 1.1.1.3.2.1 yamt 2) Fixed a possible memory leak in the _OSI support 652 1.1.1.3.2.1 yamt 3) Removed an unused variable in the predefined name support 653 1.1.1.3.2.1 yamt 4) Windows OSL: remove obsolete reference to a memory list field 654 1.1.1.3.2.1 yamt 655 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 656 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 657 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 658 1.1.1.3.2.1 yamt has a much larger code and data size. 659 1.1.1.3.2.1 yamt 660 1.1.1.3.2.1 yamt Current Release: 661 1.1.1.3.2.1 yamt Non-Debug Version: 95.2K Code, 26.4K Data, 121.6K Total 662 1.1.1.3.2.1 yamt Debug Version: 183.0K Code, 76.0K Data, 259.0K Total 663 1.1.1.3.2.1 yamt Previous Release: 664 1.1.1.3.2.1 yamt Non-Debug Version: 95.6K Code, 26.8K Data, 122.4K Total 665 1.1.1.3.2.1 yamt Debug Version: 183.5K Code, 76.6K Data, 260.1K Total 666 1.1.1.3.2.1 yamt 667 1.1.1.3.2.1 yamt 668 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 669 1.1.1.3.2.1 yamt 670 1.1.1.3.2.1 yamt AcpiExec: Added installation of a handler for the SystemCMOS address 671 1.1.1.3.2.1 yamt space. This prevents control method abort if a method accesses this 672 1.1.1.3.2.1 yamt space. 673 1.1.1.3.2.1 yamt 674 1.1.1.3.2.1 yamt AcpiExec: Added support for multiple EC devices, and now install EC 675 1.1.1.3.2.1 yamt operation region handler(s) at the actual EC device instead of the 676 1.1.1.3.2.1 yamt namespace root. This reflects the typical behavior of host operating 677 1.1.1.3.2.1 yamt systems. 678 1.1.1.3.2.1 yamt 679 1.1.1.3.2.1 yamt AcpiExec: Updated to ensure that all operation region handlers are 680 1.1.1.3.2.1 yamt installed before the _REG methods are executed. This prevents a _REG 681 1.1.1.3.2.1 yamt method from aborting if it accesses an address space has no handler. 682 1.1.1.3.2.1 yamt AcpiExec installs a handler for every possible address space. 683 1.1.1.3.2.1 yamt 684 1.1.1.3.2.1 yamt Debugger: Enhanced the "handlers" command to display non-root handlers. 685 1.1.1.3.2.1 yamt This change enhances the handlers command to display handlers associated 686 1.1.1.3.2.1 yamt with individual devices throughout the namespace, in addition to the 687 1.1.1.3.2.1 yamt currently supported display of handlers associated with the root 688 1.1.1.3.2.1 yamt namespace 689 1.1.1.3.2.1 yamt node. 690 1.1.1.3.2.1 yamt 691 1.1.1.3.2.1 yamt ASL Test Suite: Several test suite errors have been identified and 692 1.1.1.3.2.1 yamt resolved, reducing the total error count during execution. Chao Guan. 693 1.1.1.3.2.1 yamt 694 1.1.1.3.2.1 yamt ---------------------------------------- 695 1.1.1.3.2.1 yamt 28 March 2013. Summary of changes for version 20130328: 696 1.1.1.3.2.1 yamt 697 1.1.1.3.2.1 yamt 1) ACPICA kernel-resident subsystem: 698 1.1.1.3.2.1 yamt 699 1.1.1.3.2.1 yamt Fixed several possible race conditions with the internal object reference 700 1.1.1.3.2.1 yamt counting mechanism. Some of the external ACPICA interfaces update object 701 1.1.1.3.2.1 yamt reference counts without holding the interpreter or namespace lock. This 702 1.1.1.3.2.1 yamt change adds a spinlock to protect reference count updates on the internal 703 1.1.1.3.2.1 yamt ACPICA objects. Reported by and with assistance from Andriy Gapon 704 1.1.1.3.2.1 yamt (avg (a] FreeBSD.org). 705 1.1.1.3.2.1 yamt 706 1.1.1.3.2.1 yamt FADT support: Removed an extraneous warning for very large GPE register 707 1.1.1.3.2.1 yamt sets. This change removes a size mismatch warning if the legacy length 708 1.1.1.3.2.1 yamt field for a GPE register set is larger than the 64-bit GAS structure can 709 1.1.1.3.2.1 yamt accommodate. GPE register sets can be larger than the 255-bit width 710 1.1.1.3.2.1 yamt limitation of the GAS structure. Linn Crosetto (linn (a] hp.com). 711 1.1.1.3.2.1 yamt 712 1.1.1.3.2.1 yamt _OSI Support: handle any errors from AcpiOsAcquireMutex. Check for error 713 1.1.1.3.2.1 yamt return from this interface. Handles a possible timeout case if 714 1.1.1.3.2.1 yamt ACPI_WAIT_FOREVER is modified by the host to be a value less than 715 1.1.1.3.2.1 yamt "forever". Jung-uk Kim. 716 1.1.1.3.2.1 yamt 717 1.1.1.3.2.1 yamt Predefined name support: Add allowed/required argument type information 718 1.1.1.3.2.1 yamt to 719 1.1.1.3.2.1 yamt the master predefined info table. This change adds the infrastructure to 720 1.1.1.3.2.1 yamt enable typechecking on incoming arguments for all predefined 721 1.1.1.3.2.1 yamt methods/objects. It does not actually contain the code that will fully 722 1.1.1.3.2.1 yamt utilize this information, this is still under development. Also condenses 723 1.1.1.3.2.1 yamt some duplicate code for the predefined names into a new module, 724 1.1.1.3.2.1 yamt utilities/utpredef.c 725 1.1.1.3.2.1 yamt 726 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 727 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 728 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 729 1.1.1.3.2.1 yamt has a much larger code and data size. 730 1.1.1.3.2.1 yamt 731 1.1.1.3.2.1 yamt Previous Release: 732 1.1.1.3.2.1 yamt Non-Debug Version: 95.0K Code, 25.9K Data, 120.9K Total 733 1.1.1.3.2.1 yamt Debug Version: 182.9K Code, 75.6K Data, 258.5K Total 734 1.1.1.3.2.1 yamt Current Release: 735 1.1.1.3.2.1 yamt Non-Debug Version: 95.2K Code, 26.4K Data, 121.6K Total 736 1.1.1.3.2.1 yamt Debug Version: 183.0K Code, 76.0K Data, 259.0K Total 737 1.1.1.3.2.1 yamt 738 1.1.1.3.2.1 yamt 739 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 740 1.1.1.3.2.1 yamt 741 1.1.1.3.2.1 yamt iASL: Implemented a new option to simplify the development of ACPI- 742 1.1.1.3.2.1 yamt related 743 1.1.1.3.2.1 yamt BIOS code. Adds support for a new "offset table" output file. The -so 744 1.1.1.3.2.1 yamt option will create a C table containing the AML table offsets of various 745 1.1.1.3.2.1 yamt named objects in the namespace so that BIOS code can modify them easily 746 1.1.1.3.2.1 yamt at 747 1.1.1.3.2.1 yamt boot time. This can simplify BIOS runtime code by eliminating expensive 748 1.1.1.3.2.1 yamt searches for "magic values", enhancing boot times and adding greater 749 1.1.1.3.2.1 yamt reliability. With assistance from Lee Hamel. 750 1.1.1.3.2.1 yamt 751 1.1.1.3.2.1 yamt iASL: Allow additional predefined names to return zero-length packages. 752 1.1.1.3.2.1 yamt Now, all predefined names that are defined by the ACPI specification to 753 1.1.1.3.2.1 yamt return a "variable-length package of packages" are allowed to return a 754 1.1.1.3.2.1 yamt zero length top-level package. This allows the BIOS to tell the host that 755 1.1.1.3.2.1 yamt the requested feature is not supported, and supports existing BIOS/ASL 756 1.1.1.3.2.1 yamt code and practices. 757 1.1.1.3.2.1 yamt 758 1.1.1.3.2.1 yamt iASL: Changed the "result not used" warning to an error. This is the case 759 1.1.1.3.2.1 yamt where an ASL operator is effectively a NOOP because the result of the 760 1.1.1.3.2.1 yamt operation is not stored anywhere. For example: 761 1.1.1.3.2.1 yamt Add (4, Local0) 762 1.1.1.3.2.1 yamt There is no target (missing 3rd argument), nor is the function return 763 1.1.1.3.2.1 yamt value used. This is potentially a very serious problem -- since the code 764 1.1.1.3.2.1 yamt was probably intended to do something, but for whatever reason, the value 765 1.1.1.3.2.1 yamt was not stored. Therefore, this issue has been upgraded from a warning to 766 1.1.1.3.2.1 yamt an error. 767 1.1.1.3.2.1 yamt 768 1.1.1.3.2.1 yamt AcpiHelp: Added allowable/required argument types to the predefined names 769 1.1.1.3.2.1 yamt info display. This feature utilizes the recent update to the predefined 770 1.1.1.3.2.1 yamt names table (above). 771 1.1.1.3.2.1 yamt 772 1.1.1.3.2.1 yamt ---------------------------------------- 773 1.1.1.3.2.1 yamt 14 February 2013. Summary of changes for version 20130214: 774 1.1.1.3.2.1 yamt 775 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 776 1.1.1.3.2.1 yamt 777 1.1.1.3.2.1 yamt Fixed a possible regression on some hosts: Reinstated the safe return 778 1.1.1.3.2.1 yamt macros (return_ACPI_STATUS, etc.) that ensure that the argument is 779 1.1.1.3.2.1 yamt evaluated only once. Although these macros are not needed for the ACPICA 780 1.1.1.3.2.1 yamt code itself, they are often used by ACPI-related host device drivers 781 1.1.1.3.2.1 yamt where 782 1.1.1.3.2.1 yamt the safe feature may be necessary. 783 1.1.1.3.2.1 yamt 784 1.1.1.3.2.1 yamt Fixed several issues related to the ACPI 5.0 reduced hardware support 785 1.1.1.3.2.1 yamt (SOC): Now ensure that if the platform declares itself as hardware- 786 1.1.1.3.2.1 yamt reduced 787 1.1.1.3.2.1 yamt via the FADT, the following functions become NOOPs (and always return 788 1.1.1.3.2.1 yamt AE_OK) because ACPI is always enabled by definition on these machines: 789 1.1.1.3.2.1 yamt AcpiEnable 790 1.1.1.3.2.1 yamt AcpiDisable 791 1.1.1.3.2.1 yamt AcpiHwGetMode 792 1.1.1.3.2.1 yamt AcpiHwSetMode 793 1.1.1.3.2.1 yamt 794 1.1.1.3.2.1 yamt Dynamic Object Repair: Implemented additional runtime repairs for 795 1.1.1.3.2.1 yamt predefined name return values. Both of these repairs can simplify code in 796 1.1.1.3.2.1 yamt the related device drivers that invoke these methods: 797 1.1.1.3.2.1 yamt 1) For the _STR and _MLS names, automatically repair/convert an ASCII 798 1.1.1.3.2.1 yamt string to a Unicode buffer. 799 1.1.1.3.2.1 yamt 2) For the _CRS, _PRS, and _DMA names, return a resource descriptor with 800 1.1.1.3.2.1 yamt a 801 1.1.1.3.2.1 yamt lone end tag descriptor in the following cases: A Return(0) was executed, 802 1.1.1.3.2.1 yamt a null buffer was returned, or no object at all was returned (non-slack 803 1.1.1.3.2.1 yamt mode only). Adds a new file, nsconvert.c 804 1.1.1.3.2.1 yamt ACPICA BZ 998. Bob Moore, Lv Zheng. 805 1.1.1.3.2.1 yamt 806 1.1.1.3.2.1 yamt Resource Manager: Added additional code to prevent possible infinite 807 1.1.1.3.2.1 yamt loops 808 1.1.1.3.2.1 yamt while traversing corrupted or ill-formed resource template buffers. Check 809 1.1.1.3.2.1 yamt for zero-length resource descriptors in all code that loops through 810 1.1.1.3.2.1 yamt resource templates (the length field is used to index through the 811 1.1.1.3.2.1 yamt template). This change also hardens the external AcpiWalkResources and 812 1.1.1.3.2.1 yamt AcpiWalkResourceBuffer interfaces. 813 1.1.1.3.2.1 yamt 814 1.1.1.3.2.1 yamt Local Cache Manager: Enhanced the main data structure to eliminate an 815 1.1.1.3.2.1 yamt unnecessary mechanism to access the next object in the list. Actually 816 1.1.1.3.2.1 yamt provides a small performance enhancement for hosts that use the local 817 1.1.1.3.2.1 yamt ACPICA cache manager.

This change incorporates late changes 836 1.1.1.3.2.1 yamt that were made to the ACPI 5.0 specification. 837 1.1.1.3.2.1 yamt 838 1.1.1.3.2.1 yamt iASL/Disassembler: Added full support for the following new ACPI tables: 839 1.1.1.3.2.1 yamt 1) The MTMR table (MID Timer Table) 840 1.1.1.3.2.1 yamt 2) The VRTC table (Virtual Real Time Clock Table). 841 1.1.1.3.2.1 yamt Includes header file, disassembler, table compiler, and template support 842 1.1.1.3.2.1 yamt for both tables. 843 1.1.1.3.2.1 yamt 844 1.1.1.3.2.1 yamt iASL: Implemented compile-time validation of package objects returned by 845 1.1.1.3.2.1 yamt predefined names. This new feature validates static package objects 846 1.1.1.3.2.1 yamt returned by the various predefined names defined to return packages. Both 847 1.1.1.3.2.1 yamt object types and package lengths are validated, for both parent packages 848 1.1.1.3.2.1 yamt and sub-packages, if any. The code is similar in structure and behavior 849 1.1.1.3.2.1 yamt to 850 1.1.1.3.2.1 yamt the runtime repair mechanism within the AML interpreter and uses the 851 1.1.1.3.2.1 yamt existing predefined name information table. Adds a new file, aslprepkg.c. 852 1.1.1.3.2.1 yamt ACPICA BZ 938. 853 1.1.1.3.2.1 yamt 854 1.1.1.3.2.1 yamt iASL: Implemented auto-detection of binary ACPI tables for disassembly. 855 1.1.1.3.2.1 yamt This feature detects a binary file with a valid ACPI table header and 856 1.1.1.3.2.1 yamt invokes the disassembler automatically. Eliminates the need to 857 1.1.1.3.2.1 yamt specifically invoke the disassembler with the -d option. ACPICA BZ 862. 858 1.1.1.3.2.1 yamt 859 1.1.1.3.2.1 yamt iASL/Disassembler: Added several warnings for the case where there are 860 1.1.1.3.2.1 yamt unresolved control methods during the disassembly. This can potentially 861 1.1.1.3.2.1 yamt cause errors when the output file is compiled, because the disassembler 862 1.1.1.3.2.1 yamt assumes zero method arguments in these cases (it cannot determine the 863 1.1.1.3.2.1 yamt actual number of arguments without resolution/definition of the method). 864 1.1.1.3.2.1 yamt 865 1.1.1.3.2.1 yamt Debugger: Added support to display all resources with a single command. 866 1.1.1.3.2.1 yamt Invocation of the resources command with no arguments will now display 867 1.1.1.3.2.1 yamt all 868 1.1.1.3.2.1 yamt resources within the current namespace. 869 1.1.1.3.2.1 yamt 870 1.1.1.3.2.1 yamt AcpiHelp: Added descriptive text for each ACPICA exception code displayed 871 1.1.1.3.2.1 yamt via the -e option. 872 1.1.1.3.2.1 yamt 873 1.1.1.3.2.1 yamt ---------------------------------------- 874 1.1.1.3.2.1 yamt 17 January 2013. Summary of changes for version 20130117: 875 1.1.1.3.2.1 yamt 876 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 877 1.1.1.3.2.1 yamt 878 1.1.1.3.2.1 yamt Updated the AcpiGetSleepTypeData interface: Allow the \_Sx methods to 879 1.1.1.3.2.1 yamt return either 1 or 2 integers. Although the ACPI spec defines the \_Sx 880 1.1.1.3.2.1 yamt objects to return a package containing one integer, most BIOS code 881 1.1.1.3.2.1 yamt returns 882 1.1.1.3.2.1 yamt two integers and the previous code reflects that. However, we also need 883 1.1.1.3.2.1 yamt to 884 1.1.1.3.2.1 yamt support BIOS code that actually implements to the ACPI spec, and this 885 1.1.1.3.2.1 yamt change reflects this. 886 1.1.1.3.2.1 yamt 887 1.1.1.3.2.1 yamt Fixed two issues with the ACPI_DEBUG_PRINT macros: 888 1.1.1.3.2.1 yamt 1) Added the ACPI_DO_WHILE macro to the main DEBUG_PRINT helper macro for 889 1.1.1.3.2.1 yamt C compilers that require this support. 890 1.1.1.3.2.1 yamt 2) Renamed the internal ACPI_DEBUG macro to ACPI_DO_DEBUG_PRINT since 891 1.1.1.3.2.1 yamt ACPI_DEBUG is already used by many of the various hosts. 892 1.1.1.3.2.1 yamt 893 1.1.1.3.2.1 yamt Updated all ACPICA copyrights and signons to 2013. Added the 2013 894 1.1.1.3.2.1 yamt copyright to all module headers and signons, including the standard Linux 895 1.1.1.3.2.1 yamt header. This affects virtually every file in the ACPICA core subsystem, 896 1.1.1.3.2.1 yamt iASL compiler, all ACPICA utilities, and the test suites. 897 1.1.1.3.2.1 yamt 898 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 899 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 900 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 901 1.1.1.3.2.1 yamt has a much larger code and data size. 902 1.1.1.3.2.1 yamt 903 1.1.1.3.2.1 yamt Previous Release: 904 1.1.1.3.2.1 yamt Non-Debug Version: 94.5K Code, 25.5K Data, 120.0K Total 905 1.1.1.3.2.1 yamt Debug Version: 182.2K Code, 74.9K Data, 257.1K Total 906 1.1.1.3.2.1 yamt Current Release: 907 1.1.1.3.2.1 yamt Non-Debug Version: 94.5K Code, 25.4K Data, 119.9K Total 908 1.1.1.3.2.1 yamt Debug Version: 182.3K Code, 75.0K Data, 257.3K Total 909 1.1.1.3.2.1 yamt 910 1.1.1.3.2.1 yamt 911 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 912 1.1.1.3.2.1 yamt 913 1.1.1.3.2.1 yamt Generic Unix OSL: Use a buffer to eliminate multiple vfprintf()s and 914 1.1.1.3.2.1 yamt prevent a possible fault on some hosts. Some C libraries modify the arg 915 1.1.1.3.2.1 yamt pointer parameter to vfprintf making it difficult to call it twice in the 916 1.1.1.3.2.1 yamt AcpiOsVprintf function. Use a local buffer to workaround this issue. This 917 1.1.1.3.2.1 yamt does not affect the Windows OSL since the Win C library does not modify 918 1.1.1.3.2.1 yamt the arg pointer. Chao Guan, Bob Moore. 919 1.1.1.3.2.1 yamt 920 1.1.1.3.2.1 yamt iASL: Fixed a possible infinite loop when the maximum error count is 921 1.1.1.3.2.1 yamt reached. If an output file other than the .AML file is specified (such as 922 1.1.1.3.2.1 yamt a listing file), and the maximum number of errors is reached, do not 923 1.1.1.3.2.1 yamt attempt to flush data to the output file(s) as the compiler is aborting. 924 1.1.1.3.2.1 yamt This can cause an infinite loop as the max error count code essentially 925 1.1.1.3.2.1 yamt keeps calling itself. 926 1.1.1.3.2.1 yamt 927 1.1.1.3.2.1 yamt iASL/Disassembler: Added an option (-in) to ignore NOOP 928 1.1.1.3.2.1 yamt opcodes/operators. 929 1.1.1.3.2.1 yamt Implemented for both the compiler and the disassembler. Often, the NOOP 930 1.1.1.3.2.1 yamt opcode is used as padding for packages that are changed dynamically by 931 1.1.1.3.2.1 yamt the 932 1.1.1.3.2.1 yamt BIOS. When disassembled and recompiled, these NOOPs will cause syntax 933 1.1.1.3.2.1 yamt errors. This option causes the disassembler to ignore all NOOP opcodes 934 1.1.1.3.2.1 yamt (0xA3), and it also causes the compiler to ignore all ASL source code 935 1.1.1.3.2.1 yamt NOOP 936 1.1.1.3.2.1 yamt statements as well. 937 1.1.1.3.2.1 yamt 938 1.1.1.3.2.1 yamt Debugger: Enhanced the Sleep command to execute all sleep states. This 939 1.1.1.3.2.1 yamt change allows Sleep to be invoked with no arguments and causes the 940 1.1.1.3.2.1 yamt debugger to execute all of the sleep states, 0-5, automatically. 941 1.1.1.3.2.1 yamt 942 1.1.1.3.2.1 yamt ---------------------------------------- 943 1.1.1.3.2.1 yamt 20 December 2012. Summary of changes for version 20121220: 944 1.1.1.3.2.1 yamt 945 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 946 1.1.1.3.2.1 yamt 947 1.1.1.3.2.1 yamt Implemented a new interface, AcpiWalkResourceBuffer. This interface is an 948 1.1.1.3.2.1 yamt alternate entry point for AcpiWalkResources and improves the usability of 949 1.1.1.3.2.1 yamt the resource manager by accepting as input a buffer containing the output 950 1.1.1.3.2.1 yamt of either a _CRS, _PRS, or _AEI method. The key functionality is that the 951 1.1.1.3.2.1 yamt input buffer is not deleted by this interface so that it can be used by 952 1.1.1.3.2.1 yamt the host later. See the ACPICA reference for details. 953 1.1.1.3.2.1 yamt 954 1.1.1.3.2.1 yamt Interpreter: Add a warning if a 64-bit constant appears in a 32-bit table 955 1.1.1.3.2.1 yamt (DSDT version < 2). The constant will be truncated and this warning 956 1.1.1.3.2.1 yamt reflects that behavior. 957 1.1.1.3.2.1 yamt 958 1.1.1.3.2.1 yamt Resource Manager: Add support for the new ACPI 5.0 wake bit in the IRQ, 959 1.1.1.3.2.1 yamt ExtendedInterrupt, and GpioInt descriptors. This change adds support to 960 1.1.1.3.2.1 yamt both get and set the new wake bit in these descriptors, separately from 961 1.1.1.3.2.1 yamt the existing share bit. Reported by Aaron Lu. 962 1.1.1.3.2.1 yamt 963 1.1.1.3.2.1 yamt Interpreter: Fix Store() when an implicit conversion is not possible. For 964 1.1.1.3.2.1 yamt example, in the cases such as a store of a string to an existing package 965 1.1.1.3.2.1 yamt object, implement the store as a CopyObject(). This is a small departure 966 1.1.1.3.2.1 yamt from the ACPI specification which states that the control method should 967 1.1.1.3.2.1 yamt be 968 1.1.1.3.2.1 yamt aborted in this case. However, the ASLTS suite depends on this behavior. 969 1.1.1.3.2.1 yamt 970 1.1.1.3.2.1 yamt Performance improvement for the various FUNCTION_TRACE and DEBUG_PRINT 971 1.1.1.3.2.1 yamt macros: check if debug output is currently enabled as soon as possible to 972 1.1.1.3.2.1 yamt minimize performance impact if debug is in fact not enabled. 973 1.1.1.3.2.1 yamt 974 1.1.1.3.2.1 yamt Source code restructuring: Cleanup to improve modularity. The following 975 1.1.1.3.2.1 yamt new files have been added: dbconvert.c, evhandler.c, nsprepkg.c, 976 1.1.1.3.2.1 yamt psopinfo.c, psobject.c, rsdumpinfo.c, utstring.c, and utownerid.c. 977 1.1.1.3.2.1 yamt Associated makefiles and project files have been updated. 978 1.1.1.3.2.1 yamt 979 1.1.1.3.2.1 yamt Changed an exception code for LoadTable operator. For the case where one 980 1.1.1.3.2.1 yamt of the input strings is too long, change the returned exception code from 981 1.1.1.3.2.1 yamt AE_BAD_PARAMETER to AE_AML_STRING_LIMIT. 982 1.1.1.3.2.1 yamt 983 1.1.1.3.2.1 yamt Fixed a possible memory leak in dispatcher error path. On error, delete 984 1.1.1.3.2.1 yamt the mutex object created during method mutex creation. Reported by 985 1.1.1.3.2.1 yamt tim.gardner (a] canonical.com. 986 1.1.1.3.2.1 yamt 987 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 988 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler.

The AML grammar 1004 1.1.1.3.2.1 yamt will not allow the interpreter to differentiate between a method and a 1005 1.1.1.3.2.1 yamt method invocation when these are used as an argument to the ObjectType 1006 1.1.1.3.2.1 yamt operator. The ACPI specification change is to disallow a method 1007 1.1.1.3.2.1 yamt invocation 1008 1.1.1.3.2.1 yamt (UserTerm) for the ObjectType operator. 1009 1.1.1.3.2.1 yamt 1010 1.1.1.3.2.1 yamt Finish support for the TPM2 and CSRT tables in the headers, table 1011 1.1.1.3.2.1 yamt compiler, and disassembler. 1012 1.1.1.3.2.1 yamt 1013 1.1.1.3.2.1 yamt Unix user-space OSL: Fix a problem with WaitSemaphore where the timeout 1014 1.1.1.3.2.1 yamt always expires immediately if the semaphore is not available. The 1015 1.1.1.3.2.1 yamt original 1016 1.1.1.3.2.1 yamt code was using a relative-time timeout, but sem_timedwait requires the 1017 1.1.1.3.2.1 yamt use 1018 1.1.1.3.2.1 yamt of an absolute time. 1019 1.1.1.3.2.1 yamt 1020 1.1.1.3.2.1 yamt iASL: Added a remark if the Timer() operator is used within a 32-bit 1021 1.1.1.3.2.1 yamt table. This operator returns a 64-bit time value that will be truncated 1022 1.1.1.3.2.1 yamt within a 32-bit table. 1023 1.1.1.3.2.1 yamt 1024 1.1.1.3.2.1 yamt iASL Source code restructuring: Cleanup to improve modularity. The 1025 1.1.1.3.2.1 yamt following new files have been added: aslhex.c, aslxref.c, aslnamesp.c, 1026 1.1.1.3.2.1 yamt aslmethod.c, and aslfileio.c. Associated makefiles and project files have 1027 1.1.1.3.2.1 yamt been updated. 1028 1.1.1.3.2.1 yamt 1029 1.1.1.3.2.1 yamt 1030 1.1.1.3.2.1 yamt ---------------------------------------- 1031 1.1.1.3.2.1 yamt 14 November 2012. Summary of changes for version 20121114: 1032 1.1.1.3.2.1 yamt 1033 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 1034 1.1.1.3.2.1 yamt 1035 1.1.1.3.2.1 yamt Implemented a performance enhancement for ACPI/AML Package objects. This 1036 1.1.1.3.2.1 yamt change greatly increases the performance of Package objects within the 1037 1.1.1.3.2.1 yamt interpreter. It changes the processing of reference counts for packages 1038 1.1.1.3.2.1 yamt by 1039 1.1.1.3.2.1 yamt optimizing for the most common case where the package sub-objects are 1040 1.1.1.3.2.1 yamt either Integers, Strings, or Buffers. Increases the overall performance 1041 1.1.1.3.2.1 yamt of 1042 1.1.1.3.2.1 yamt the ASLTS test suite by 1.5X (Increases the Slack Mode performance by 1043 1.1.1.3.2.1 yamt 2X.) 1044 1.1.1.3.2.1 yamt Chao Guan. ACPICA BZ 943. 1045 1.1.1.3.2.1 yamt 1046 1.1.1.3.2.1 yamt Implemented and deployed common macros to extract flag bits from resource 1047 1.1.1.3.2.1 yamt descriptors. Improves readability and maintainability of the code. Fixes 1048 1.1.1.3.2.1 yamt a 1049 1.1.1.3.2.1 yamt problem with the UART serial bus descriptor for the number of data bits 1050 1.1.1.3.2.1 yamt flags (was incorrectly 2 bits, should be 3). 1051 1.1.1.3.2.1 yamt 1052 1.1.1.3.2.1 yamt Enhanced the ACPI_GETx and ACPI_SETx macros. Improved the implementation 1053 1.1.1.3.2.1 yamt of the macros and changed the SETx macros to the style of (destination, 1054 1.1.1.3.2.1 yamt source). Also added ACPI_CASTx companion macros. Lv Zheng. 1055 1.1.1.3.2.1 yamt 1056 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 1057 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler.

This change 1072 1.1.1.3.2.1 yamt adds the ShareAndWake and ExclusiveAndWake flags which were added to the 1073 1.1.1.3.2.1 yamt Irq, Interrupt, and Gpio resource descriptors in ACPI 5.0. ACPICA BZ 986. 1074 1.1.1.3.2.1 yamt 1075 1.1.1.3.2.1 yamt Disassembler: Fixed a problem with external declaration generation. Fixes 1076 1.1.1.3.2.1 yamt a problem where an incorrect pathname could be generated for an external 1077 1.1.1.3.2.1 yamt declaration if the original reference to the object includes leading 1078 1.1.1.3.2.1 yamt carats (^). ACPICA BZ 984. 1079 1.1.1.3.2.1 yamt 1080 1.1.1.3.2.1 yamt Debugger: Completed a major update for the Disassemble<method> command. 1081 1.1.1.3.2.1 yamt This command was out-of-date and did not properly disassemble control 1082 1.1.1.3.2.1 yamt methods that had any reasonable complexity. This fix brings the command 1083 1.1.1.3.2.1 yamt up 1084 1.1.1.3.2.1 yamt to the same level as the rest of the disassembler. Adds one new file, 1085 1.1.1.3.2.1 yamt dmdeferred.c, which is existing code that is now common with the main 1086 1.1.1.3.2.1 yamt disassembler and the debugger disassemble command. ACPICA MZ 978. 1087 1.1.1.3.2.1 yamt 1088 1.1.1.3.2.1 yamt iASL: Moved the parser entry prototype to avoid a duplicate declaration. 1089 1.1.1.3.2.1 yamt Newer versions of Bison emit this prototype, so moved the prototype out 1090 1.1.1.3.2.1 yamt of 1091 1.1.1.3.2.1 yamt the iASL header to where it is actually used in order to avoid a 1092 1.1.1.3.2.1 yamt duplicate 1093 1.1.1.3.2.1 yamt declaration. 1094 1.1.1.3.2.1 yamt 1095 1.1.1.3.2.1 yamt iASL/Tools: Standardized use of the stream I/O functions: 1096 1.1.1.3.2.1 yamt 1) Ensure check for I/O error after every fopen/fread/fwrite 1097 1.1.1.3.2.1 yamt 2) Ensure proper order of size/count arguments for fread/fwrite 1098 1.1.1.3.2.1 yamt 3) Use test of (Actual != Requested) after all fwrite, and most fread 1099 1.1.1.3.2.1 yamt 4) Standardize I/O error messages 1100 1.1.1.3.2.1 yamt Improves reliability and maintainability of the code.

Originally intended to force the 1122 1.1.1.3.2.1 yamt compiler/disassembler into an ACPI 2.0 mode, this was never implemented 1123 1.1.1.3.2.1 yamt and the entire concept is now obsolete. 1124 1.1.1.3.2.1 yamt 1125 1.1.1.3.2.1 yamt ---------------------------------------- 1126 1.1.1.3.2.1 yamt 18 October 2012. Summary of changes for version 20121018: 1127 1.1.1.3.2.1 yamt 1128 1.1.1.3.2.1 yamt 1129 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 1130 1.1.1.3.2.1 yamt 1131 1.1.1.3.2.1 yamt Updated support for the ACPI 5.0 MPST table. Fixes some problems 1132 1.1.1.3.2.1 yamt introduced by late changes to the table as it was added to the ACPI 5.0 1133 1.1.1.3.2.1 yamt specification. Includes header, disassembler, and data table compiler 1134 1.1.1.3.2.1 yamt support as well as a new version of the MPST template. 1135 1.1.1.3.2.1 yamt 1136 1.1.1.3.2.1 yamt AcpiGetObjectInfo: Enhanced the device object support to include the ACPI 1137 1.1.1.3.2.1 yamt 5.0 _SUB method. Now calls _SUB in addition to the other PNP-related ID 1138 1.1.1.3.2.1 yamt methods: _HID, _CID, and _UID. 1139 1.1.1.3.2.1 yamt 1140 1.1.1.3.2.1 yamt Changed ACPI_DEVICE_ID to ACPI_PNP_DEVICE_ID. Also changed 1141 1.1.1.3.2.1 yamt ACPI_DEVICE_ID_LIST to ACPI_PNP_DEVICE_ID_LIST. These changes prevent 1142 1.1.1.3.2.1 yamt name collisions on hosts that reserve the *_DEVICE_ID (or *DeviceId) 1143 1.1.1.3.2.1 yamt names for their various drivers. Affects the AcpiGetObjectInfo external 1144 1.1.1.3.2.1 yamt interface, and other internal interfaces as well. 1145 1.1.1.3.2.1 yamt 1146 1.1.1.3.2.1 yamt Added and deployed a new macro for ACPI_NAME management: ACPI_MOVE_NAME. 1147 1.1.1.3.2.1 yamt This macro resolves to a simple 32-bit move of the 4-character ACPI_NAME 1148 1.1.1.3.2.1 yamt on machines that support non-aligned transfers. Optimizes for this case 1149 1.1.1.3.2.1 yamt rather than using a strncpy. With assistance from Zheng Lv. 1150 1.1.1.3.2.1 yamt 1151 1.1.1.3.2.1 yamt Resource Manager: Small fix for buffer size calculation. Fixed a one byte 1152 1.1.1.3.2.1 yamt error in the output buffer calculation. Feng Tang. ACPICA BZ 849. 1153 1.1.1.3.2.1 yamt 1154 1.1.1.3.2.1 yamt Added a new debug print message for AML mutex objects that are force- 1155 1.1.1.3.2.1 yamt released. At control method termination, any currently acquired mutex 1156 1.1.1.3.2.1 yamt objects are force-released. Adds a new debug-only message for each one 1157 1.1.1.3.2.1 yamt that is released. 1158 1.1.1.3.2.1 yamt 1159 1.1.1.3.2.1 yamt Audited/updated all ACPICA return macros and the function debug depth 1160 1.1.1.3.2.1 yamt counter: 1) Ensure that all functions that use the various TRACE macros 1161 1.1.1.3.2.1 yamt also use the appropriate ACPICA return macros. 2) Ensure that all normal 1162 1.1.1.3.2.1 yamt return statements surround the return expression (value) with parens to 1163 1.1.1.3.2.1 yamt ensure consistency across the ACPICA code base. Guan Chao, Tang Feng, 1164 1.1.1.3.2.1 yamt Zheng Lv, Bob Moore. ACPICA Bugzilla 972. 1165 1.1.1.3.2.1 yamt 1166 1.1.1.3.2.1 yamt Global source code changes/maintenance: All extra lines at the start and 1167 1.1.1.3.2.1 yamt end of each source file have been removed for consistency. Also, within 1168 1.1.1.3.2.1 yamt comments, all new sentences start with a single space instead of a double 1169 1.1.1.3.2.1 yamt space, again for consistency across the code base. 1170 1.1.1.3.2.1 yamt 1171 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 1172 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 1173 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 1174 1.1.1.3.2.1 yamt has a much larger code and data size. 1175 1.1.1.3.2.1 yamt 1176 1.1.1.3.2.1 yamt Previous Release: 1177 1.1.1.3.2.1 yamt Non-Debug Version: 93.7K Code, 25.3K Data, 119.0K Total 1178 1.1.1.3.2.1 yamt Debug Version: 175.0K Code, 74.4K Data, 249.4K Total 1179 1.1.1.3.2.1 yamt Current Release: 1180 1.1.1.3.2.1 yamt Non-Debug Version: 93.9K Code, 25.2K Data, 119.1K Total 1181 1.1.1.3.2.1 yamt Debug Version: 175.5K Code, 74.5K Data, 250.0K Total 1182 1.1.1.3.2.1 yamt 1183 1.1.1.3.2.1 yamt 1184 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 1185 1.1.1.3.2.1 yamt 1186 1.1.1.3.2.1 yamt AcpiExec: Improved the algorithm used for memory leak/corruption 1187 1.1.1.3.2.1 yamt detection. Added some intelligence to the code that maintains the global 1188 1.1.1.3.2.1 yamt list of allocated memory. The list is now ordered by allocated memory 1189 1.1.1.3.2.1 yamt address, significantly improving performance. When running AcpiExec on 1190 1.1.1.3.2.1 yamt the ASLTS test suite, speed improvements of 3X to 5X are seen, depending 1191 1.1.1.3.2.1 yamt on the platform and/or the environment. Note, this performance 1192 1.1.1.3.2.1 yamt enhancement affects the AcpiExec utility only, not the kernel-resident 1193 1.1.1.3.2.1 yamt ACPICA code. 1194 1.1.1.3.2.1 yamt 1195 1.1.1.3.2.1 yamt Enhanced error reporting for invalid AML opcodes and bad ACPI_NAMEs. For 1196 1.1.1.3.2.1 yamt the disassembler, dump the 48 bytes surrounding the invalid opcode. Fix 1197 1.1.1.3.2.1 yamt incorrect table offset reported for invalid opcodes. Report the original 1198 1.1.1.3.2.1 yamt 32-bit value for bad ACPI_NAMEs (as well as the repaired name.) 1199 1.1.1.3.2.1 yamt 1200 1.1.1.3.2.1 yamt Disassembler: Enhanced the -vt option to emit the binary table data in 1201 1.1.1.3.2.1 yamt hex format to assist with debugging. 1202 1.1.1.3.2.1 yamt 1203 1.1.1.3.2.1 yamt Fixed a potential filename buffer overflow in osunixdir.c. Increased the 1204 1.1.1.3.2.1 yamt size of file structure. Colin Ian King. 1205 1.1.1.3.2.1 yamt 1206 1.1.1.3.2.1 yamt ---------------------------------------- 1207 1.1.1.3.2.1 yamt 13 September 2012. Summary of changes for version 20120913: 1208 1.1.1.3.2.1 yamt 1209 1.1.1.3.2.1 yamt 1210 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 1211 1.1.1.3.2.1 yamt 1212 1.1.1.3.2.1 yamt ACPI 5.0: Added two new notify types for the Hardware Error Notification 1213 1.1.1.3.2.1 yamt Structure within the Hardware Error Source Table (HEST) table -- CMCI(5) 1214 1.1.1.3.2.1 yamt and 1215 1.1.1.3.2.1 yamt MCE(6). 1216 1.1.1.3.2.1 yamt 1217 1.1.1.3.2.1 yamt Table Manager: Merged/removed duplicate code in the root table resize 1218 1.1.1.3.2.1 yamt functions. One function is external, the other is internal. Lv Zheng, 1219 1.1.1.3.2.1 yamt ACPICA 1220 1.1.1.3.2.1 yamt BZ 846. 1221 1.1.1.3.2.1 yamt 1222 1.1.1.3.2.1 yamt Makefiles: Completely removed the obsolete "Linux" makefiles under 1223 1.1.1.3.2.1 yamt acpica/generate/linux. These makefiles are obsolete and have been 1224 1.1.1.3.2.1 yamt replaced 1225 1.1.1.3.2.1 yamt by 1226 1.1.1.3.2.1 yamt the generic unix makefiles under acpica/generate/unix. 1227 1.1.1.3.2.1 yamt 1228 1.1.1.3.2.1 yamt Makefiles: Ensure that binary files always copied properly. Minor rule 1229 1.1.1.3.2.1 yamt change 1230 1.1.1.3.2.1 yamt to ensure that the final binary output files are always copied up to the 1231 1.1.1.3.2.1 yamt appropriate binary directory (bin32 or bin64.) 1232 1.1.1.3.2.1 yamt 1233 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 1234 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 1235 1.1.1.3.2.1 yamt debug 1236 1.1.1.3.2.1 yamt version of the code includes the debug output trace mechanism and has a 1237 1.1.1.3.2.1 yamt much 1238 1.1.1.3.2.1 yamt larger code and data size. 1239 1.1.1.3.2.1 yamt 1240 1.1.1.3.2.1 yamt Previous Release: 1241 1.1.1.3.2.1 yamt Non-Debug Version: 93.8K Code, 25.3K Data, 119.1K Total 1242 1.1.1.3.2.1 yamt Debug Version: 175.7K Code, 74.8K Data, 250.5K Total 1243 1.1.1.3.2.1 yamt Current Release: 1244 1.1.1.3.2.1 yamt Non-Debug Version: 93.7K Code, 25.3K Data, 119.0K Total 1245 1.1.1.3.2.1 yamt Debug Version: 175.0K Code, 74.4K Data, 249.4K Total 1246 1.1.1.3.2.1 yamt 1247 1.1.1.3.2.1 yamt 1248 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 1249 1.1.1.3.2.1 yamt 1250 1.1.1.3.2.1 yamt Disassembler: Fixed a possible fault during the disassembly of resource 1251 1.1.1.3.2.1 yamt descriptors when a second parse is required because of the invocation of 1252 1.1.1.3.2.1 yamt external control methods within the table. With assistance from 1253 1.1.1.3.2.1 yamt adq (a] lidskialf.net. ACPICA BZ 976. 1254 1.1.1.3.2.1 yamt 1255 1.1.1.3.2.1 yamt iASL: Fixed a namepath optimization problem. An error can occur if the 1256 1.1.1.3.2.1 yamt parse 1257 1.1.1.3.2.1 yamt node that contains the namepath to be optimized does not have a parent 1258 1.1.1.3.2.1 yamt node 1259 1.1.1.3.2.1 yamt that is a named object. This change fixes the problem. 1260 1.1.1.3.2.1 yamt 1261 1.1.1.3.2.1 yamt iASL: Fixed a regression where the AML file is not deleted on errors. The 1262 1.1.1.3.2.1 yamt AML 1263 1.1.1.3.2.1 yamt output file should be deleted if there are any errors during the 1264 1.1.1.3.2.1 yamt compiler. 1265 1.1.1.3.2.1 yamt The 1266 1.1.1.3.2.1 yamt only exception is if the -f (force output) option is used. ACPICA BZ 974. 1267 1.1.1.3.2.1 yamt 1268 1.1.1.3.2.1 yamt iASL: Added a feature to automatically increase internal line buffer 1269 1.1.1.3.2.1 yamt sizes. 1270 1.1.1.3.2.1 yamt Via realloc(), automatically increase the internal line buffer sizes as 1271 1.1.1.3.2.1 yamt necessary to support very long source code lines. The current version of 1272 1.1.1.3.2.1 yamt the 1273 1.1.1.3.2.1 yamt preprocessor requires a buffer long enough to contain full source code 1274 1.1.1.3.2.1 yamt lines. 1275 1.1.1.3.2.1 yamt This change increases the line buffer(s) if the input lines go beyond the 1276 1.1.1.3.2.1 yamt current buffer size. This eliminates errors that occurred when a source 1277 1.1.1.3.2.1 yamt code 1278 1.1.1.3.2.1 yamt line was longer than the buffer. 1279 1.1.1.3.2.1 yamt 1280 1.1.1.3.2.1 yamt iASL: Fixed a problem with constant folding in method declarations. The 1281 1.1.1.3.2.1 yamt SyncLevel term is a ByteConstExpr, and incorrect code would be generated 1282 1.1.1.3.2.1 yamt if a 1283 1.1.1.3.2.1 yamt Type3 opcode was used. 1284 1.1.1.3.2.1 yamt 1285 1.1.1.3.2.1 yamt Debugger: Improved command help support. For incorrect argument count, 1286 1.1.1.3.2.1 yamt display 1287 1.1.1.3.2.1 yamt full help for the command. For help command itself, allow an argument to 1288 1.1.1.3.2.1 yamt specify a command. 1289 1.1.1.3.2.1 yamt 1290 1.1.1.3.2.1 yamt Test Suites: Several bug fixes for the ASLTS suite reduces the number of 1291 1.1.1.3.2.1 yamt errors during execution of the suite. Guan Chao. 1292 1.1.1.3.2.1 yamt 1293 1.1.1.3.2.1 yamt ---------------------------------------- 1294 1.1.1.3.2.1 yamt 16 August 2012. Summary of changes for version 20120816: 1295 1.1.1.3.2.1 yamt 1296 1.1.1.3.2.1 yamt 1297 1.1.1.3.2.1 yamt 1) ACPICA Kernel-resident Subsystem: 1298 1.1.1.3.2.1 yamt 1299 1.1.1.3.2.1 yamt Removed all use of the deprecated _GTS and _BFS predefined methods. The 1300 1.1.1.3.2.1 yamt _GTS 1301 1.1.1.3.2.1 yamt (Going To Sleep) and _BFS (Back From Sleep) methods are essentially 1302 1.1.1.3.2.1 yamt deprecated and will probably be removed from the ACPI specification. 1303 1.1.1.3.2.1 yamt Windows 1304 1.1.1.3.2.1 yamt does not invoke them, and reportedly never will. The final nail in the 1305 1.1.1.3.2.1 yamt coffin 1306 1.1.1.3.2.1 yamt is that the ACPI specification states that these methods must be run with 1307 1.1.1.3.2.1 yamt interrupts off, which is not going to happen in a kernel interpreter. 1308 1.1.1.3.2.1 yamt Note: 1309 1.1.1.3.2.1 yamt Linux has removed all use of the methods also. It was discovered that 1310 1.1.1.3.2.1 yamt invoking these functions caused failures on some machines, probably 1311 1.1.1.3.2.1 yamt because 1312 1.1.1.3.2.1 yamt they were never tested since Windows does not call them. Affects two 1313 1.1.1.3.2.1 yamt external 1314 1.1.1.3.2.1 yamt interfaces, AcpiEnterSleepState and AcpiLeaveSleepStatePrep. Tang Feng. 1315 1.1.1.3.2.1 yamt ACPICA BZ 969. 1316 1.1.1.3.2.1 yamt 1317 1.1.1.3.2.1 yamt Implemented support for complex bit-packed buffers returned from the _PLD 1318 1.1.1.3.2.1 yamt (Physical Location of Device) predefined method. Adds a new external 1319 1.1.1.3.2.1 yamt interface, AcpiDecodePldBuffer that parses the buffer into a more usable 1320 1.1.1.3.2.1 yamt C 1321 1.1.1.3.2.1 yamt structure. Note: C Bitfields cannot be used for this type of predefined 1322 1.1.1.3.2.1 yamt structure since the memory layout of individual bitfields is not defined 1323 1.1.1.3.2.1 yamt by 1324 1.1.1.3.2.1 yamt the C language. In addition, there are endian concerns where a compiler 1325 1.1.1.3.2.1 yamt will 1326 1.1.1.3.2.1 yamt change the bitfield ordering based on the machine type. The new ACPICA 1327 1.1.1.3.2.1 yamt interface eliminates these issues, and should be called after _PLD is 1328 1.1.1.3.2.1 yamt executed. ACPICA BZ 954. 1329 1.1.1.3.2.1 yamt 1330 1.1.1.3.2.1 yamt Implemented a change to allow a scope change to root (via "Scope (\)") 1331 1.1.1.3.2.1 yamt during 1332 1.1.1.3.2.1 yamt execution of module-level ASL code (code that is executed at table load 1333 1.1.1.3.2.1 yamt time.) Lin Ming. 1334 1.1.1.3.2.1 yamt 1335 1.1.1.3.2.1 yamt Added the Windows8/Server2012 string for the _OSI method. This change 1336 1.1.1.3.2.1 yamt adds 1337 1.1.1.3.2.1 yamt a 1338 1.1.1.3.2.1 yamt new _OSI string, "Windows 2012" for both Windows 8 and Windows Server 1339 1.1.1.3.2.1 yamt 2012. 1340 1.1.1.3.2.1 yamt 1341 1.1.1.3.2.1 yamt Added header support for the new ACPI tables DBG2 (Debug Port Table Type 1342 1.1.1.3.2.1 yamt 2) 1343 1.1.1.3.2.1 yamt and CSRT (Core System Resource Table). 1344 1.1.1.3.2.1 yamt 1345 1.1.1.3.2.1 yamt Added struct header support for the _FDE, _GRT, _GTM, and _SRT predefined 1346 1.1.1.3.2.1 yamt names. This simplifies access to the buffers returned by these predefined 1347 1.1.1.3.2.1 yamt names. Adds a new file, include/acbuffer.h. ACPICA BZ 956. 1348 1.1.1.3.2.1 yamt 1349 1.1.1.3.2.1 yamt GPE support: Removed an extraneous parameter from the various low-level 1350 1.1.1.3.2.1 yamt internal GPE functions. Tang Feng. 1351 1.1.1.3.2.1 yamt 1352 1.1.1.3.2.1 yamt Removed the linux makefiles from the unix packages. The generate/linux 1353 1.1.1.3.2.1 yamt makefiles are obsolete and have been removed from the unix tarball 1354 1.1.1.3.2.1 yamt release 1355 1.1.1.3.2.1 yamt packages.

Fixes the External() 1644 1.1.1.3.2.1 yamt generation 1645 1.1.1.3.2.1 yamt for 1646 1.1.1.3.2.1 yamt the Create* field, Alias, and Scope operators: 1647 1.1.1.3.2.1 yamt 1) Create* buffer field operators - fix type mismatch warning on 1648 1.1.1.3.2.1 yamt disassembly 1649 1.1.1.3.2.1 yamt 2) Alias - implement missing External support 1650 1.1.1.3.2.1 yamt 3) Scope - fix to make sure all necessary externals are emitted. 1651 1.1.1.3.2.1 yamt 1652 1.1.1.3.2.1 yamt iASL: Improved pathname support. For include files, merge the prefix 1653 1.1.1.3.2.1 yamt pathname 1654 1.1.1.3.2.1 yamt with the file pathname and eliminate unnecessary components. Convert 1655 1.1.1.3.2.1 yamt backslashes in all pathnames to forward slashes, for readability. Include 1656 1.1.1.3.2.1 yamt file 1657 1.1.1.3.2.1 yamt pathname changes affect both #include and Include() type operators. 1658 1.1.1.3.2.1 yamt 1659 1.1.1.3.2.1 yamt iASL/DTC/Preprocessor: Gracefully handle early EOF. Handle an EOF at the 1660 1.1.1.3.2.1 yamt end 1661 1.1.1.3.2.1 yamt of a valid line by inserting a newline and then returning the EOF during 1662 1.1.1.3.2.1 yamt the 1663 1.1.1.3.2.1 yamt next call to GetNextLine. Prevents the line from being ignored due to EOF 1664 1.1.1.3.2.1 yamt condition. 1665 1.1.1.3.2.1 yamt 1666 1.1.1.3.2.1 yamt iASL: Implemented some changes to enhance the IDE support (-vi option.) 1667 1.1.1.3.2.1 yamt Error 1668 1.1.1.3.2.1 yamt and Warning messages are now correctly recognized for both the source 1669 1.1.1.3.2.1 yamt code 1670 1.1.1.3.2.1 yamt browser and the global error and warning counts. 1671 1.1.1.3.2.1 yamt 1672 1.1.1.3.2.1 yamt ---------------------------------------- 1673 1.1.1.3.2.1 yamt 20 April 2012. Summary of changes for version 20120420: 1674 1.1.1.3.2.1 yamt 1675 1.1.1.3.2.1 yamt 1676 1.1.1.3.2.1 yamt 1) ACPICA Core Subsystem: 1677 1.1.1.3.2.1 yamt 1678 1.1.1.3.2.1 yamt Implemented support for multiple notify handlers. This change adds 1679 1.1.1.3.2.1 yamt support 1680 1.1.1.3.2.1 yamt to 1681 1.1.1.3.2.1 yamt allow multiple system and device notify handlers on Device, Thermal Zone, 1682 1.1.1.3.2.1 yamt and 1683 1.1.1.3.2.1 yamt Processor objects. This can simplify the host OS notification 1684 1.1.1.3.2.1 yamt implementation. 1685 1.1.1.3.2.1 yamt Also re-worked and restructured the entire notify support code to 1686 1.1.1.3.2.1 yamt simplify 1687 1.1.1.3.2.1 yamt handler installation, handler removal, notify event queuing, and notify 1688 1.1.1.3.2.1 yamt dispatch to handler(s). Note: there can still only be two global notify 1689 1.1.1.3.2.1 yamt handlers - one for system notifies and one for device notifies. There are 1690 1.1.1.3.2.1 yamt no 1691 1.1.1.3.2.1 yamt changes to the existing handler install/remove interfaces. Lin Ming, Bob 1692 1.1.1.3.2.1 yamt Moore, Rafael Wysocki. 1693 1.1.1.3.2.1 yamt 1694 1.1.1.3.2.1 yamt Fixed a regression in the package repair code where the object reference 1695 1.1.1.3.2.1 yamt count was calculated incorrectly. Regression was introduced in the commit 1696 1.1.1.3.2.1 yamt "Support to add Package wrappers". 1697 1.1.1.3.2.1 yamt 1698 1.1.1.3.2.1 yamt Fixed a couple possible memory leaks in the AML parser, in the error 1699 1.1.1.3.2.1 yamt recovery 1700 1.1.1.3.2.1 yamt path. Jesper Juhl, Lin Ming. 1701 1.1.1.3.2.1 yamt 1702 1.1.1.3.2.1 yamt Example Code and Data Size: These are the sizes for the OS-independent 1703 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 1704 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 1705 1.1.1.3.2.1 yamt has a 1706 1.1.1.3.2.1 yamt much larger code and data size. 1707 1.1.1.3.2.1 yamt 1708 1.1.1.3.2.1 yamt Previous Release: 1709 1.1.1.3.2.1 yamt Non-Debug Version: 92.9K Code, 25.0K Data, 117.9K Total 1710 1.1.1.3.2.1 yamt Debug Version: 172.5K Code, 73.2K Data, 245.7K Total 1711 1.1.1.3.2.1 yamt Current Release: 1712 1.1.1.3.2.1 yamt Non-Debug Version: 92.9K Code, 25.0K Data, 117.9K Total 1713 1.1.1.3.2.1 yamt Debug Version: 172.6K Code, 73.4K Data, 246.0K Total 1714 1.1.1.3.2.1 yamt 1715 1.1.1.3.2.1 yamt 1716 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 1717 1.1.1.3.2.1 yamt 1718 1.1.1.3.2.1 yamt iASL: Fixed a problem with the resource descriptor support where the 1719 1.1.1.3.2.1 yamt length 1720 1.1.1.3.2.1 yamt of the StartDependentFn and StartDependentFnNoPrio descriptors were not 1721 1.1.1.3.2.1 yamt included in cumulative descriptor offset, resulting in incorrect values 1722 1.1.1.3.2.1 yamt for 1723 1.1.1.3.2.1 yamt resource tags within resource descriptors appearing after a 1724 1.1.1.3.2.1 yamt StartDependent* 1725 1.1.1.3.2.1 yamt descriptor. Reported by Petr Vandrovec. ACPICA BZ 949. 1726 1.1.1.3.2.1 yamt 1727 1.1.1.3.2.1 yamt iASL and Preprocessor: Implemented full support for the #line directive 1728 1.1.1.3.2.1 yamt to 1729 1.1.1.3.2.1 yamt correctly track original source file line numbers through the .i 1730 1.1.1.3.2.1 yamt preprocessor 1731 1.1.1.3.2.1 yamt output file - for error and warning messages. 1732 1.1.1.3.2.1 yamt 1733 1.1.1.3.2.1 yamt iASL: Expand the allowable byte constants for address space IDs. 1734 1.1.1.3.2.1 yamt Previously, 1735 1.1.1.3.2.1 yamt the allowable range was 0x80-0xFF (user-defined spaces), now the range is 1736 1.1.1.3.2.1 yamt 0x0A-0xFF to allow for custom and new IDs without changing the compiler. 1737 1.1.1.3.2.1 yamt 1738 1.1.1.3.2.1 yamt iASL: Add option to treat all warnings as errors (-we). ACPICA BZ 948. 1739 1.1.1.3.2.1 yamt 1740 1.1.1.3.2.1 yamt iASL: Add option to completely disable the preprocessor (-Pn). 1741 1.1.1.3.2.1 yamt 1742 1.1.1.3.2.1 yamt iASL: Now emit all error/warning messages to standard error (stderr) by 1743 1.1.1.3.2.1 yamt default (instead of the previous stdout). 1744 1.1.1.3.2.1 yamt 1745 1.1.1.3.2.1 yamt ASL Test Suite (ASLTS): Reduce iASL warnings due to use of Switch(). 1746 1.1.1.3.2.1 yamt Update 1747 1.1.1.3.2.1 yamt for resource descriptor offset fix above. Update/cleanup error output 1748 1.1.1.3.2.1 yamt routines. Enable and send iASL errors/warnings to an error logfile 1749 1.1.1.3.2.1 yamt (error.txt). Send all other iASL output to a logfile (compiler.txt). 1750 1.1.1.3.2.1 yamt Fixed 1751 1.1.1.3.2.1 yamt several extraneous "unrecognized operator" messages. 1752 1.1.1.3.2.1 yamt 1753 1.1.1.3.2.1 yamt ---------------------------------------- 1754 1.1.1.3.2.1 yamt 20 March 2012. Summary of changes for version 20120320: 1755 1.1.1.3.2.1 yamt 1756 1.1.1.3.2.1 yamt 1757 1.1.1.3.2.1 yamt 1) ACPICA Core Subsystem: 1758 1.1.1.3.2.1 yamt 1759 1.1.1.3.2.1 yamt Enhanced the sleep/wake interfaces to optionally execute the _GTS method 1760 1.1.1.3.2.1 yamt (Going To Sleep) and the _BFS method (Back From Sleep). Windows 1761 1.1.1.3.2.1 yamt apparently 1762 1.1.1.3.2.1 yamt does not execute these methods, and therefore these methods are often 1763 1.1.1.3.2.1 yamt untested. It has been seen on some systems where the execution of these 1764 1.1.1.3.2.1 yamt methods causes errors and also prevents the machine from entering S5. It 1765 1.1.1.3.2.1 yamt is 1766 1.1.1.3.2.1 yamt therefore suggested that host operating systems do not execute these 1767 1.1.1.3.2.1 yamt methods 1768 1.1.1.3.2.1 yamt by default. In the future, perhaps these methods can be optionally 1769 1.1.1.3.2.1 yamt executed 1770 1.1.1.3.2.1 yamt based on the age of the system and/or what is the newest version of 1771 1.1.1.3.2.1 yamt Windows 1772 1.1.1.3.2.1 yamt that the BIOS asks for via _OSI. Changed interfaces: AcpiEnterSleepState 1773 1.1.1.3.2.1 yamt and 1774 1.1.1.3.2.1 yamt AcpileaveSleepStatePrep. See the ACPICA reference and Linux BZ 13041. Lin 1775 1.1.1.3.2.1 yamt Ming. 1776 1.1.1.3.2.1 yamt 1777 1.1.1.3.2.1 yamt Fixed a problem where the length of the local/common FADT was set too 1778 1.1.1.3.2.1 yamt early. 1779 1.1.1.3.2.1 yamt The local FADT table length cannot be set to the common length until the 1780 1.1.1.3.2.1 yamt original length has been examined. There is code that checks the table 1781 1.1.1.3.2.1 yamt length 1782 1.1.1.3.2.1 yamt and sets various fields appropriately. This can affect older machines 1783 1.1.1.3.2.1 yamt with 1784 1.1.1.3.2.1 yamt early FADT versions. For example, this can cause inadvertent writes to 1785 1.1.1.3.2.1 yamt the 1786 1.1.1.3.2.1 yamt CST_CNT register. Julian Anastasov. 1787 1.1.1.3.2.1 yamt 1788 1.1.1.3.2.1 yamt Fixed a mapping issue related to a physical table override. Use the 1789 1.1.1.3.2.1 yamt deferred 1790 1.1.1.3.2.1 yamt mapping mechanism for tables loaded via the physical override OSL 1791 1.1.1.3.2.1 yamt interface. 1792 1.1.1.3.2.1 yamt This allows for early mapping before the virtual memory manager is 1793 1.1.1.3.2.1 yamt available. 1794 1.1.1.3.2.1 yamt Thomas Renninger, Bob Moore. 1795 1.1.1.3.2.1 yamt 1796 1.1.1.3.2.1 yamt Enhanced the automatic return-object repair code: Repair a common problem 1797 1.1.1.3.2.1 yamt with 1798 1.1.1.3.2.1 yamt predefined methods that are defined to return a variable-length Package 1799 1.1.1.3.2.1 yamt of 1800 1.1.1.3.2.1 yamt sub-objects. If there is only one sub-object, some BIOS ASL code 1801 1.1.1.3.2.1 yamt mistakenly 1802 1.1.1.3.2.1 yamt simply returns the single object instead of a Package with one sub- 1803 1.1.1.3.2.1 yamt object. 1804 1.1.1.3.2.1 yamt This new support will repair this error by wrapping a Package object 1805 1.1.1.3.2.1 yamt around 1806 1.1.1.3.2.1 yamt the original object, creating the correct and expected Package with one 1807 1.1.1.3.2.1 yamt sub- 1808 1.1.1.3.2.1 yamt object. Names that can be repaired in this manner include: _ALR, _CSD, 1809 1.1.1.3.2.1 yamt _HPX, 1810 1.1.1.3.2.1 yamt _MLS, _PLD, _PRT, _PSS, _TRT, _TSS, _BCL, _DOD, _FIX, and _Sx.

This will simplify BIOS development process by 1837 1.1.1.3.2.1 yamt eliminating 1838 1.1.1.3.2.1 yamt the need for a separate preprocessing step during builds. On Windows, it 1839 1.1.1.3.2.1 yamt also 1840 1.1.1.3.2.1 yamt eliminates the need to install a separate C compiler. ACPICA BZ 761. Some 1841 1.1.1.3.2.1 yamt features including full #define() macro support are still under 1842 1.1.1.3.2.1 yamt development. 1843 1.1.1.3.2.1 yamt These preprocessor directives are supported: 1844 1.1.1.3.2.1 yamt #define 1845 1.1.1.3.2.1 yamt #elif 1846 1.1.1.3.2.1 yamt #else 1847 1.1.1.3.2.1 yamt #endif 1848 1.1.1.3.2.1 yamt #error 1849 1.1.1.3.2.1 yamt #if 1850 1.1.1.3.2.1 yamt #ifdef 1851 1.1.1.3.2.1 yamt #ifndef 1852 1.1.1.3.2.1 yamt #include 1853 1.1.1.3.2.1 yamt #pragma message 1854 1.1.1.3.2.1 yamt #undef 1855 1.1.1.3.2.1 yamt #warning 1856 1.1.1.3.2.1 yamt In addition, these new command line options are supported: 1857 1.1.1.3.2.1 yamt -D <symbol> Define symbol for preprocessor use 1858 1.1.1.3.2.1 yamt -li Create preprocessed output file (*.i) 1859 1.1.1.3.2.1 yamt -P Preprocess only and create preprocessor output file (*.i) 1860 1.1.1.3.2.1 yamt 1861 1.1.1.3.2.1 yamt Table Compiler: Fixed a problem where the equals operator within an 1862 1.1.1.3.2.1 yamt expression 1863 1.1.1.3.2.1 yamt did not work properly. 1864 1.1.1.3.2.1 yamt 1865 1.1.1.3.2.1 yamt Updated iASL to use the current versions of Bison/Flex. Updated the 1866 1.1.1.3.2.1 yamt Windows 1867 1.1.1.3.2.1 yamt project file to invoke these tools from the standard location. ACPICA BZ 1868 1.1.1.3.2.1 yamt 904. 1869 1.1.1.3.2.1 yamt Versions supported: 1870 1.1.1.3.2.1 yamt Flex for Windows: V2.5.4 1871 1.1.1.3.2.1 yamt Bison for Windows: V2.4.1 1872 1.1.1.3.2.1 yamt 1873 1.1.1.3.2.1 yamt ---------------------------------------- 1874 1.1.1.3.2.1 yamt 15 February 2012. Summary of changes for version 20120215: 1875 1.1.1.3.2.1 yamt 1876 1.1.1.3.2.1 yamt 1877 1.1.1.3.2.1 yamt 1) ACPICA Core Subsystem: 1878 1.1.1.3.2.1 yamt 1879 1.1.1.3.2.1 yamt There have been some major changes to the sleep/wake support code, as 1880 1.1.1.3.2.1 yamt described below (a - e). 1881 1.1.1.3.2.1 yamt 1882 1.1.1.3.2.1 yamt a) The AcpiLeaveSleepState has been split into two interfaces, similar to 1883 1.1.1.3.2.1 yamt AcpiEnterSleepStatePrep and AcpiEnterSleepState. The new interface is 1884 1.1.1.3.2.1 yamt AcpiLeaveSleepStatePrep. This allows the host to perform actions between 1885 1.1.1.3.2.1 yamt the 1886 1.1.1.3.2.1 yamt time the _BFS method is called and the _WAK method is called. NOTE: all 1887 1.1.1.3.2.1 yamt hosts 1888 1.1.1.3.2.1 yamt must update their wake/resume code or else sleep/wake will not work 1889 1.1.1.3.2.1 yamt properly. 1890 1.1.1.3.2.1 yamt Rafael Wysocki. 1891 1.1.1.3.2.1 yamt 1892 1.1.1.3.2.1 yamt b) In AcpiLeaveSleepState, now enable all runtime GPEs before calling the 1893 1.1.1.3.2.1 yamt _WAK 1894 1.1.1.3.2.1 yamt method. Some machines require that the GPEs are enabled before the _WAK 1895 1.1.1.3.2.1 yamt method 1896 1.1.1.3.2.1 yamt is executed. Thomas Renninger. 1897 1.1.1.3.2.1 yamt 1898 1.1.1.3.2.1 yamt c) In AcpiLeaveSleepState, now always clear the WAK_STS (wake status) 1899 1.1.1.3.2.1 yamt bit. 1900 1.1.1.3.2.1 yamt Some BIOS code assumes that WAK_STS will be cleared on resume and use it 1901 1.1.1.3.2.1 yamt to 1902 1.1.1.3.2.1 yamt determine whether the system is rebooting or resuming. Matthew Garrett. 1903 1.1.1.3.2.1 yamt 1904 1.1.1.3.2.1 yamt d) Move the invocations of _GTS (Going To Sleep) and _BFS (Back From 1905 1.1.1.3.2.1 yamt Sleep) to 1906 1.1.1.3.2.1 yamt match the ACPI specification requirement. Rafael Wysocki. 1907 1.1.1.3.2.1 yamt 1908 1.1.1.3.2.1 yamt e) Implemented full support for the ACPI 5.0 SleepStatus and SleepControl 1909 1.1.1.3.2.1 yamt registers within the V5 FADT. This support adds two new files: 1910 1.1.1.3.2.1 yamt hardware/hwesleep.c implements the support for the new registers. Moved 1911 1.1.1.3.2.1 yamt all 1912 1.1.1.3.2.1 yamt sleep/wake external interfaces to hardware/hwxfsleep.c. 1913 1.1.1.3.2.1 yamt 1914 1.1.1.3.2.1 yamt 1915 1.1.1.3.2.1 yamt Added a new OSL interface for ACPI table overrides, 1916 1.1.1.3.2.1 yamt AcpiOsPhysicalTableOverride. This interface allows the host to override a 1917 1.1.1.3.2.1 yamt table via a physical address, instead of the logical address required by 1918 1.1.1.3.2.1 yamt AcpiOsTableOverride. This simplifies the host implementation. Initial 1919 1.1.1.3.2.1 yamt implementation by Thomas Renninger. The ACPICA implementation creates a 1920 1.1.1.3.2.1 yamt single 1921 1.1.1.3.2.1 yamt shared function for table overrides that attempts both a logical and a 1922 1.1.1.3.2.1 yamt physical override. 1923 1.1.1.3.2.1 yamt 1924 1.1.1.3.2.1 yamt Expanded the OSL memory read/write interfaces to 64-bit data 1925 1.1.1.3.2.1 yamt (AcpiOsReadMemory, AcpiOsWriteMemory.)

Also simplified the 2316 1.1.1.3.2.1 yamt makefiles 2317 1.1.1.3.2.1 yamt considerably through the use of the vpath variable to specify search 2318 1.1.1.3.2.1 yamt paths. 2319 1.1.1.3.2.1 yamt ACPICA BZ 924. 2320 1.1.1.3.2.1 yamt 2321 1.1.1.3.2.1 yamt 2) iASL Compiler/Disassembler and Tools: 2322 1.1.1.3.2.1 yamt 2323 1.1.1.3.2.1 yamt iASL: Implemented support to check the access length for all fields 2324 1.1.1.3.2.1 yamt created to 2325 1.1.1.3.2.1 yamt access named Resource Descriptor fields. For example, if a resource field 2326 1.1.1.3.2.1 yamt is 2327 1.1.1.3.2.1 yamt defined to be two bits, a warning is issued if a CreateXxxxField() is 2328 1.1.1.3.2.1 yamt used 2329 1.1.1.3.2.1 yamt with an incorrect bit length. This is implemented for all current 2330 1.1.1.3.2.1 yamt resource 2331 1.1.1.3.2.1 yamt descriptor names. ACPICA BZ 930. 2332 1.1.1.3.2.1 yamt 2333 1.1.1.3.2.1 yamt Disassembler: Fixed a byte ordering problem with the output of 24-bit and 2334 1.1.1.3.2.1 yamt 56- 2335 1.1.1.3.2.1 yamt bit integers. 2336 1.1.1.3.2.1 yamt 2337 1.1.1.3.2.1 yamt iASL: Fixed a couple of issues associated with variable-length package 2338 1.1.1.3.2.1 yamt objects. 1) properly handle constants like One, Ones, Zero -- do not make 2339 1.1.1.3.2.1 yamt a 2340 1.1.1.3.2.1 yamt VAR_PACKAGE when these are used as a package length. 2) Allow the 2341 1.1.1.3.2.1 yamt VAR_PACKAGE 2342 1.1.1.3.2.1 yamt opcode (in addition to PACKAGE) when validating object types for 2343 1.1.1.3.2.1 yamt predefined 2344 1.1.1.3.2.1 yamt names. 2345 1.1.1.3.2.1 yamt 2346 1.1.1.3.2.1 yamt iASL: Emit statistics for all output files (instead of just the ASL input 2347 1.1.1.3.2.1 yamt and 2348 1.1.1.3.2.1 yamt AML output). Includes listings, hex files, etc. 2349 1.1.1.3.2.1 yamt 2350 1.1.1.3.2.1 yamt iASL: Added -G option to the table compiler to allow the compilation of 2351 1.1.1.3.2.1 yamt custom 2352 1.1.1.3.2.1 yamt ACPI tables. The only part of a table that is required is the standard 2353 1.1.1.3.2.1 yamt 36- 2354 1.1.1.3.2.1 yamt byte 2355 1.1.1.3.2.1 yamt ACPI header. 2356 1.1.1.3.2.1 yamt 2357 1.1.1.3.2.1 yamt AcpiXtract: Ported to the standard ACPICA environment (with ACPICA 2358 1.1.1.3.2.1 yamt headers), 2359 1.1.1.3.2.1 yamt which also adds correct 64-bit support. Also, now all output filenames 2360 1.1.1.3.2.1 yamt are 2361 1.1.1.3.2.1 yamt completely lower case. 2362 1.1.1.3.2.1 yamt 2363 1.1.1.3.2.1 yamt AcpiExec: Ignore any non-AML tables (tables other than DSDT or SSDT) when 2364 1.1.1.3.2.1 yamt loading table files. A warning is issued for any such tables. The only 2365 1.1.1.3.2.1 yamt exception is an FADT. This also fixes a possible fault when attempting to 2366 1.1.1.3.2.1 yamt load 2367 1.1.1.3.2.1 yamt non-AML tables. ACPICA BZ 932. 2368 1.1.1.3.2.1 yamt 2369 1.1.1.3.2.1 yamt AcpiHelp: Added the AccessAs and Offset operators. Fixed a problem where 2370 1.1.1.3.2.1 yamt a 2371 1.1.1.3.2.1 yamt missing table terminator could cause a fault when using the -p option. 2372 1.1.1.3.2.1 yamt 2373 1.1.1.3.2.1 yamt AcpiSrc: Fixed a possible divide-by-zero fault when generating file 2374 1.1.1.3.2.1 yamt statistics. 2375 1.1.1.3.2.1 yamt 2376 1.1.1.3.2.1 yamt 3) Example Code and Data Size 2377 1.1.1.3.2.1 yamt 2378 1.1.1.3.2.1 yamt These are the sizes for the OS-independent acpica.lib produced by the 2379 1.1.1.3.2.1 yamt Microsoft Visual C++ 9.0 32-bit compiler.

Summary of changes for version 20110623: 2394 1.1.1.3 jruoho 2395 1.1.1.3 jruoho 1) ACPI CA Core Subsystem: 2396 1.1.1.3 jruoho 2397 1.1.1.3.2.1 yamt Updated the predefined name repair mechanism to not attempt repair of a 2398 1.1.1.3.2.1 yamt _TSS 2399 1.1.1.3.2.1 yamt return object if a _PSS object is present. We can only sort the _TSS 2400 1.1.1.3.2.1 yamt return 2401 1.1.1.3.2.1 yamt package if there is no _PSS within the same scope. This is because if 2402 1.1.1.3.2.1 yamt _PSS 2403 1.1.1.3.2.1 yamt is 2404 1.1.1.3.2.1 yamt present, the ACPI specification dictates that the _TSS Power Dissipation 2405 1.1.1.3.2.1 yamt field 2406 1.1.1.3.2.1 yamt is to be ignored, and therefore some BIOSs leave garbage values in the 2407 1.1.1.3.2.1 yamt _TSS 2408 1.1.1.3.2.1 yamt Power field(s). In this case, it is best to just return the _TSS package 2409 1.1.1.3.2.1 yamt as- 2410 1.1.1.3 jruoho is. Reported by, and fixed with assistance from Fenghua Yu. 2411 1.1.1.3 jruoho 2412 1.1.1.3.2.1 yamt Added an option to globally disable the control method return value 2413 1.1.1.3.2.1 yamt validation 2414 1.1.1.3.2.1 yamt and repair. This runtime option can be used to disable return value 2415 1.1.1.3.2.1 yamt repair 2416 1.1.1.3.2.1 yamt if 2417 1.1.1.3.2.1 yamt this is causing a problem on a particular machine. Also added an option 2418 1.1.1.3.2.1 yamt to 2419 1.1.1.3 jruoho AcpiExec (-dr) to set this disable flag. 2420 1.1.1.3 jruoho 2421 1.1.1.3.2.1 yamt All makefiles and project files: Major changes to improve generation of 2422 1.1.1.3.2.1 yamt ACPICA 2423 1.1.1.3 jruoho tools. ACPICA BZ 912: 2424 1.1.1.3 jruoho Reduce default optimization levels to improve compatibility 2425 1.1.1.3 jruoho For Linux, add strict-aliasing=0 for gcc 4 2426 1.1.1.3 jruoho Cleanup and simplify use of command line defines 2427 1.1.1.3 jruoho Cleanup multithread library support 2428 1.1.1.3 jruoho Improve usage messages 2429 1.1.1.3 jruoho 2430 1.1.1.3.2.1 yamt Linux-specific header: update handling of THREAD_ID and pthread.

This utility summarizes the ACPI specification chapters for the 2455 1.1.1.3.2.1 yamt ASL 2456 1.1.1.3 jruoho and AML languages. It generates under Linux/Unix as well as Windows, and 2457 1.1.1.3 jruoho provides the following functionality: 2458 1.1.1.3 jruoho Find/display ASL operator(s) -- with description and syntax. 2459 1.1.1.3 jruoho Find/display ASL keyword(s) -- with exact spelling and descriptions. 2460 1.1.1.3 jruoho Find/display ACPI predefined name(s) -- with description, number 2461 1.1.1.3 jruoho of arguments, and the return value data type. 2462 1.1.1.3.2.1 yamt Find/display AML opcode name(s) -- with opcode, arguments, and 2463 1.1.1.3.2.1 yamt grammar. 2464 1.1.1.3.2.1 yamt Decode/display AML opcode -- with opcode name, arguments, and 2465 1.1.1.3.2.1 yamt grammar. 2466 1.1.1.3.2.1 yamt 2467 1.1.1.3.2.1 yamt Service Layers: Make multi-thread support configurable.

The only tool that requires multi-thread support is AcpiExec. 2473 1.1.1.3 jruoho 2474 1.1.1.3.2.1 yamt iASL: Update yyerrror/AslCompilerError for "const" errors. Newer versions 2475 1.1.1.3.2.1 yamt of 2476 1.1.1.3 jruoho Bison appear to want the interface to yyerror to be a const char * (or at 2477 1.1.1.3.2.1 yamt least this is a problem when generating iASL on some systems.) ACPICA BZ 2478 1.1.1.3.2.1 yamt 923 2479 1.1.1.3 jruoho Pierre Lejeune. 2480 1.1.1.3 jruoho 2481 1.1.1.3.2.1 yamt Tools: Fix for systems where O_BINARY is not defined. Only used for 2482 1.1.1.3.2.1 yamt Windows 2483 1.1.1.3 jruoho versions of the tools. 2484 1.1.1.3 jruoho 2485 1.1.1.3 jruoho ---------------------------------------- 2486 1.1.1.3 jruoho 27 May 2011. Summary of changes for version 20110527: 2487 1.1.1.3 jruoho 2488 1.1.1.3 jruoho 1) ACPI CA Core Subsystem: 2489 1.1.1.3 jruoho 2490 1.1.1.3.2.1 yamt ASL Load() operator: Reinstate most restrictions on the incoming ACPI 2491 1.1.1.3.2.1 yamt table 2492 1.1.1.3 jruoho signature. Now, only allow SSDT, OEMx, and a null signature. History: 2493 1.1.1.3 jruoho 1) Originally, we checked the table signature for "SSDT" or "PSDT". 2494 1.1.1.3 jruoho (PSDT is now obsolete.) 2495 1.1.1.3 jruoho 2) We added support for OEMx tables, signature "OEM" plus a fourth 2496 1.1.1.3 jruoho "don't care" character. 2497 1.1.1.3 jruoho 3) Valid tables were encountered with a null signature, so we just 2498 1.1.1.3 jruoho gave up on validating the signature, (05/2008). 2499 1.1.1.3 jruoho 4) We encountered non-AML tables such as the MADT, which caused 2500 1.1.1.3 jruoho interpreter errors and kernel faults. So now, we once again allow 2501 1.1.1.3 jruoho only SSDT, OEMx, and now, also a null signature.

Affects both the core ACPICA code and the iASL 2506 1.1.1.3.2.1 yamt compiler. 2507 1.1.1.3 jruoho 2508 1.1.1.3 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2509 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 2510 1.1.1.3.2.1 yamt debug 2511 1.1.1.3.2.1 yamt version of the code includes the debug output trace mechanism and has a 2512 1.1.1.3.2.1 yamt much 2513 1.1.1.3 jruoho larger code and data size. 2514 1.1.1.3 jruoho 2515 1.1.1.3 jruoho Previous Release (VC 9.0): 2516 1.1.1.3 jruoho Non-Debug Version: 90.0K Code, 23.8K Data, 113.8K Total 2517 1.1.1.3 jruoho Debug Version: 164.5K Code, 68.0K Data, 232.5K Total 2518 1.1.1.3 jruoho Current Release (VC 9.0): 2519 1.1.1.3 jruoho Non-Debug Version: 90.1K Code, 23.9K Data, 114.0K Total 2520 1.1.1.3 jruoho Debug Version: 165.6K Code, 68.4K Data, 234.0K Total 2521 1.1.1.3 jruoho 2522 1.1.1.3 jruoho 2) iASL Compiler/Disassembler and Tools: 2523 1.1.1.3 jruoho 2524 1.1.1.3.2.1 yamt Debugger/AcpiExec: Implemented support for "complex" method arguments on 2525 1.1.1.3.2.1 yamt the 2526 1.1.1.3.2.1 yamt debugger command line. This adds support beyond simple integers -- 2527 1.1.1.3.2.1 yamt including 2528 1.1.1.3 jruoho Strings, Buffers, and Packages. Includes support for nested packages. 2529 1.1.1.3.2.1 yamt Increased the default command line buffer size to accommodate these 2530 1.1.1.3.2.1 yamt arguments. 2531 1.1.1.3 jruoho See the ACPICA reference for details and syntax. ACPICA BZ 917. 2532 1.1.1.3 jruoho 2533 1.1.1.3.2.1 yamt Debugger/AcpiExec: Implemented support for "default" method arguments for 2534 1.1.1.3.2.1 yamt the 2535 1.1.1.3.2.1 yamt Execute/Debug command. Now, the debugger will always invoke a control 2536 1.1.1.3.2.1 yamt method 2537 1.1.1.3.2.1 yamt with the required number of arguments -- even if the command line 2538 1.1.1.3.2.1 yamt specifies 2539 1.1.1.3.2.1 yamt none or insufficient arguments. It uses default integer values for any 2540 1.1.1.3.2.1 yamt missing 2541 1.1.1.3 jruoho arguments. Also fixes a bug where only six method arguments maximum were 2542 1.1.1.3 jruoho supported instead of the required seven. 2543 1.1.1.3 jruoho 2544 1.1.1.3.2.1 yamt Debugger/AcpiExec: Add a maximum buffer length parameter to AcpiOsGetLine 2545 1.1.1.3.2.1 yamt and 2546 1.1.1.3 jruoho also return status in order to prevent buffer overruns. See the ACPICA 2547 1.1.1.3 jruoho reference for details and syntax. ACPICA BZ 921 2548 1.1.1.3 jruoho 2549 1.1.1.3 jruoho iASL: Cleaned up support for Berkeley yacc. A general cleanup of code and 2550 1.1.1.3 jruoho makefiles to simplify support for the two different but similar parser 2551 1.1.1.3 jruoho generators, bison and yacc. 2552 1.1.1.3 jruoho 2553 1.1.1.3.2.1 yamt Updated the generic unix makefile for gcc 4. The default gcc version is 2554 1.1.1.3.2.1 yamt now 2555 1.1.1.3 jruoho expected to be 4 or greater, since options specific to gcc 4 are used. 2556 1.1.1.3 jruoho 2557 1.1.1.3 jruoho ---------------------------------------- 2558 1.1.1.3 jruoho 13 April 2011.

This change will force the execution of a _REG method underneath 2565 1.1.1.3.2.1 yamt the 2566 1.1.1.3 jruoho EC 2567 1.1.1.3 jruoho device even if there is no corresponding operation region of type 2568 1.1.1.3 jruoho EmbeddedControl. Fixes a problem seen on some machines and apparently is 2569 1.1.1.3 jruoho compatible with Windows behavior. ACPICA BZ 875. 2570 1.1.1.3 jruoho 2571 1.1.1.3.2.1 yamt Added more predefined methods that are eligible for automatic NULL 2572 1.1.1.3.2.1 yamt package 2573 1.1.1.3.2.1 yamt element removal. This change adds another group of predefined names to 2574 1.1.1.3.2.1 yamt the 2575 1.1.1.3 jruoho list 2576 1.1.1.3 jruoho of names that can be repaired by having NULL package elements dynamically 2577 1.1.1.3.2.1 yamt removed. This group are those methods that return a single variable- 2578 1.1.1.3.2.1 yamt length 2579 1.1.1.3.2.1 yamt package containing simple data types such as integers, buffers, strings. 2580 1.1.1.3.2.1 yamt This 2581 1.1.1.3.2.1 yamt includes: _ALx, _BCL, _CID,_ DOD, _EDL, _FIX, _PCL, _PLD, _PMD, _PRx, 2582 1.1.1.3.2.1 yamt _PSL, 2583 1.1.1.3 jruoho _Sx, 2584 1.1.1.3 jruoho and _TZD. ACPICA BZ 914. 2585 1.1.1.3 jruoho 2586 1.1.1.3 jruoho Split and segregated all internal global lock functions to a new file, 2587 1.1.1.3 jruoho evglock.c. 2588 1.1.1.3 jruoho 2589 1.1.1.3.2.1 yamt Updated internal address SpaceID for DataTable regions. Moved this 2590 1.1.1.3.2.1 yamt internal 2591 1.1.1.3 jruoho space 2592 1.1.1.3.2.1 yamt id in preparation for ACPI 5.0 changes that will include some new space 2593 1.1.1.3.2.1 yamt IDs. 2594 1.1.1.3 jruoho This 2595 1.1.1.3 jruoho change should not affect user/host code. 2596 1.1.1.3 jruoho 2597 1.1.1.3 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2598 1.1.1.3 jruoho acpica.lib 2599 1.1.1.3.2.1 yamt produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug 2600 1.1.1.3.2.1 yamt version of 2601 1.1.1.3.2.1 yamt the code includes the debug output trace mechanism and has a much larger 2602 1.1.1.3.2.1 yamt code 2603 1.1.1.3 jruoho and 2604 1.1.1.3 jruoho data size. 2605 1.1.1.3 jruoho 2606 1.1.1.3 jruoho Previous Release (VC 9.0): 2607 1.1.1.3 jruoho Non-Debug Version: 89.8K Code, 23.8K Data, 113.6K Total 2608 1.1.1.3 jruoho Debug Version: 164.2K Code, 67.9K Data, 232.1K Total 2609 1.1.1.3 jruoho Current Release (VC 9.0): 2610 1.1.1.3 jruoho Non-Debug Version: 90.0K Code, 23.8K Data, 113.8K Total 2611 1.1.1.3 jruoho Debug Version: 164.5K Code, 68.0K Data, 232.5K Total 2612 1.1.1.3 jruoho 2613 1.1.1.3 jruoho 2) iASL Compiler/Disassembler and Tools: 2614 1.1.1.3 jruoho 2615 1.1.1.3.2.1 yamt iASL/DTC: Major update for new grammar features. Allow generic data types 2616 1.1.1.3.2.1 yamt in 2617 1.1.1.3.2.1 yamt custom ACPI tables. Field names are now optional. Any line can be split 2618 1.1.1.3.2.1 yamt to 2619 1.1.1.3.2.1 yamt multiple lines using the continuation char (\). Large buffers now use 2620 1.1.1.3.2.1 yamt line- 2621 1.1.1.3 jruoho continuation character(s) and no colon on the continuation lines. See the 2622 1.1.1.3 jruoho grammar 2623 1.1.1.3.2.1 yamt update in the iASL compiler reference. ACPI BZ 910,911. Lin Ming, Bob 2624 1.1.1.3.2.1 yamt Moore. 2625 1.1.1.3 jruoho 2626 1.1.1.3.2.1 yamt iASL: Mark ASL "Return()" and the simple "Return" as "Null" return 2627 1.1.1.3.2.1 yamt statements. 2628 1.1.1.3.2.1 yamt Since the parser stuffs a "zero" as the return value for these statements 2629 1.1.1.3.2.1 yamt (due 2630 1.1.1.3 jruoho to 2631 1.1.1.3.2.1 yamt the underlying AML grammar), they were seen as "return with value" by the 2632 1.1.1.3.2.1 yamt iASL 2633 1.1.1.3.2.1 yamt semantic checking. They are now seen correctly as "null" return 2634 1.1.1.3.2.1 yamt statements. 2635 1.1.1.3.2.1 yamt 2636 1.1.1.3.2.1 yamt iASL: Check if a_REG declaration has a corresponding Operation Region. 2637 1.1.1.3.2.1 yamt Adds a 2638 1.1.1.3.2.1 yamt check for each _REG to ensure that there is in fact a corresponding 2639 1.1.1.3.2.1 yamt operation 2640 1.1.1.3 jruoho region declaration in the same scope. If not, the _REG method is not very 2641 1.1.1.3 jruoho useful 2642 1.1.1.3 jruoho since it probably won't be executed. ACPICA BZ 915. 2643 1.1.1.3 jruoho 2644 1.1.1.3.2.1 yamt iASL/DTC: Finish support for expression evaluation. Added a new 2645 1.1.1.3.2.1 yamt expression 2646 1.1.1.3 jruoho parser 2647 1.1.1.3 jruoho that implements c-style operator precedence and parenthesization. ACPICA 2648 1.1.1.3 jruoho bugzilla 2649 1.1.1.3 jruoho 908. 2650 1.1.1.3 jruoho 2651 1.1.1.3.2.1 yamt Disassembler/DTC: Remove support for () and <> style comments in data 2652 1.1.1.3.2.1 yamt tables. 2653 1.1.1.3 jruoho Now 2654 1.1.1.3.2.1 yamt that DTC has full expression support, we don't want to have comment 2655 1.1.1.3.2.1 yamt strings 2656 1.1.1.3 jruoho that 2657 1.1.1.3.2.1 yamt start with a parentheses or a less-than symbol. Now, only the standard /* 2658 1.1.1.3.2.1 yamt and 2659 1.1.1.3 jruoho // 2660 1.1.1.3 jruoho comments are supported, as well as the bracket [] comments. 2661 1.1.1.3 jruoho 2662 1.1.1.3 jruoho AcpiXtract: Fix for RSDP and dynamic SSDT extraction. These tables have 2663 1.1.1.3 jruoho "unusual" 2664 1.1.1.3.2.1 yamt headers in the acpidump file. Update the header validation to support 2665 1.1.1.3.2.1 yamt these 2666 1.1.1.3.2.1 yamt tables. Problem introduced in previous AcpiXtract version in the change 2667 1.1.1.3.2.1 yamt to 2668 1.1.1.3 jruoho support "wrong checksum" error messages emitted by acpidump utility. 2669 1.1.1.3 jruoho 2670 1.1.1.3.2.1 yamt iASL: Add a * option to generate all template files (as a synonym for 2671 1.1.1.3.2.1 yamt ALL) 2672 1.1.1.3.2.1 yamt as 2673 1.1.1.3 jruoho in 2674 1.1.1.3 jruoho "iasl -T *" or "iasl -T ALL". 2675 1.1.1.3 jruoho 2676 1.1.1.3.2.1 yamt iASL/DTC: Do not abort compiler on fatal errors. We do not want to 2677 1.1.1.3.2.1 yamt completely 2678 1.1.1.3.2.1 yamt abort the compiler on "fatal" errors, simply should abort the current 2679 1.1.1.3.2.1 yamt compile. 2680 1.1.1.3 jruoho This allows multiple compiles with a single (possibly wildcard) compiler 2681 1.1.1.3 jruoho invocation. 2682 1.1.1.3 jruoho 2683 1.1.1.3 jruoho ---------------------------------------- 2684 1.1.1.3 jruoho 16 March 2011. Summary of changes for version 20110316: 2685 1.1.1.3 jruoho 2686 1.1.1.3 jruoho 1) ACPI CA Core Subsystem: 2687 1.1.1.3 jruoho 2688 1.1.1.3.2.1 yamt Fixed a problem caused by a _PRW method appearing at the namespace root 2689 1.1.1.3.2.1 yamt scope 2690 1.1.1.3.2.1 yamt during the setup of wake GPEs. A fault could occur if a _PRW directly 2691 1.1.1.3.2.1 yamt under 2692 1.1.1.3 jruoho the 2693 1.1.1.3 jruoho root object was passed to the AcpiSetupGpeForWake interface. Lin Ming. 2694 1.1.1.3 jruoho 2695 1.1.1.3.2.1 yamt Implemented support for "spurious" Global Lock interrupts. On some 2696 1.1.1.3.2.1 yamt systems, a 2697 1.1.1.3.2.1 yamt global lock interrupt can occur without the pending flag being set. Upon 2698 1.1.1.3.2.1 yamt a 2699 1.1.1.3.2.1 yamt GL 2700 1.1.1.3.2.1 yamt interrupt, we now ensure that a thread is actually waiting for the lock 2701 1.1.1.3.2.1 yamt before 2702 1.1.1.3 jruoho signaling GL availability.

Includes support in 2723 1.1.1.3.2.1 yamt the 2724 1.1.1.3.2.1 yamt header files, disassembler, table compiler, and template generator. Bob 2725 1.1.1.3.2.1 yamt Moore, 2726 1.1.1.3 jruoho Lin Ming. 2727 1.1.1.3 jruoho 2728 1.1.1.3.2.1 yamt AcpiXtract: Correctly handle embedded comments and messages from 2729 1.1.1.3.2.1 yamt AcpiDump. 2730 1.1.1.3.2.1 yamt Apparently some or all versions of acpidump will occasionally emit a 2731 1.1.1.3.2.1 yamt comment 2732 1.1.1.3 jruoho like 2733 1.1.1.3 jruoho "Wrong checksum", etc., into the dump file. This was causing problems for 2734 1.1.1.3 jruoho AcpiXtract. ACPICA BZ 905. 2735 1.1.1.3 jruoho 2736 1.1.1.3.2.1 yamt iASL: Fix the Linux makefile by removing an inadvertent double file 2737 1.1.1.3.2.1 yamt inclusion. 2738 1.1.1.3 jruoho ACPICA BZ 913. 2739 1.1.1.3 jruoho 2740 1.1.1.3 jruoho AcpiExec: Update installation of operation region handlers. Install one 2741 1.1.1.3 jruoho handler 2742 1.1.1.3.2.1 yamt for a user-defined address space. This is used by the ASL test suite 2743 1.1.1.3.2.1 yamt (ASLTS). 2744 1.1.1.3 jruoho 2745 1.1.1.3 jruoho ---------------------------------------- 2746 1.1.1.3 jruoho 11 February 2011. Summary of changes for version 20110211: 2747 1.1 jruoho 2748 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 2749 1.1.1.2 jruoho 2750 1.1.1.3.2.1 yamt Added a mechanism to defer _REG methods for some early-installed 2751 1.1.1.3.2.1 yamt handlers. 2752 1.1.1.3.2.1 yamt Most user handlers should be installed before call to 2753 1.1.1.3.2.1 yamt AcpiEnableSubsystem. 2754 1.1.1.2 jruoho However, Event handlers and region handlers should be installed after 2755 1.1.1.3.2.1 yamt AcpiInitializeObjects. Override handlers for the "default" regions should 2756 1.1.1.3.2.1 yamt be 2757 1.1.1.2 jruoho installed early, however. This change executes all _REG methods for the 2758 1.1.1.2 jruoho default regions (Memory/IO/PCI/DataTable) simultaneously to prevent any 2759 1.1.1.2 jruoho chicken/egg issues between them. ACPICA BZ 848. 2760 1.1.1.2 jruoho 2761 1.1.1.3.2.1 yamt Implemented an optimization for GPE detection. This optimization will 2762 1.1.1.3.2.1 yamt simply 2763 1.1.1.2 jruoho ignore GPE registers that contain no enabled GPEs -- there is no need to 2764 1.1.1.2 jruoho read the register since this information is available internally. This 2765 1.1.1.3.2.1 yamt becomes more important on machines with a large GPE space. ACPICA 2766 1.1.1.3.2.1 yamt bugzilla 2767 1.1.1.2 jruoho 884. Lin Ming. Suggestion from Joe Liu. 2768 1.1.1.2 jruoho 2769 1.1.1.3.2.1 yamt Removed all use of the highly unreliable FADT revision field. The 2770 1.1.1.3.2.1 yamt revision 2771 1.1.1.3.2.1 yamt number in the FADT has been found to be completely unreliable and cannot 2772 1.1.1.3.2.1 yamt be 2773 1.1.1.3.2.1 yamt trusted. Only the actual table length can be used to infer the version. 2774 1.1.1.3.2.1 yamt This 2775 1.1.1.3.2.1 yamt change updates the ACPICA core and the disassembler so that both no 2776 1.1.1.3.2.1 yamt longer 2777 1.1.1.2 jruoho even look at the FADT version and instead depend solely upon the FADT 2778 1.1.1.2 jruoho length. 2779 1.1.1.2 jruoho 2780 1.1.1.2 jruoho Fix an unresolved name issue for the no-debug and no-error-message source 2781 1.1.1.3.2.1 yamt generation cases. The _AcpiModuleName was left undefined in these cases, 2782 1.1.1.3.2.1 yamt but 2783 1.1.1.2 jruoho it is actually needed as a parameter to some interfaces.

Summary of changes for version 20110112: 2852 1.1.1.2 jruoho 2853 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 2854 1.1.1.2 jruoho 2855 1.1.1.3.2.1 yamt Fixed a race condition between method execution and namespace walks that 2856 1.1.1.3.2.1 yamt can 2857 1.1.1.2 jruoho possibly cause a fault. The problem was apparently introduced in version 2858 1.1.1.3.2.1 yamt 20100528 as a result of a performance optimization that reduces the 2859 1.1.1.3.2.1 yamt number 2860 1.1.1.3.2.1 yamt of 2861 1.1.1.2 jruoho namespace walks upon method exit by using the delete_namespace_subtree 2862 1.1.1.3.2.1 yamt function instead of the delete_namespace_by_owner function used 2863 1.1.1.3.2.1 yamt previously. 2864 1.1.1.2 jruoho Bug is a missing namespace lock in the delete_namespace_subtree function. 2865 1.1.1.2 jruoho dana.myers (a] oracle.com 2866 1.1.1.2 jruoho 2867 1.1.1.2 jruoho Fixed several issues and a possible fault with the automatic "serialized" 2868 1.1.1.3.2.1 yamt method support. History: This support changes a method to "serialized" on 2869 1.1.1.3.2.1 yamt the 2870 1.1.1.2 jruoho fly if the method generates an AE_ALREADY_EXISTS error, indicating the 2871 1.1.1.3.2.1 yamt possibility that it cannot handle reentrancy. This fix repairs a couple 2872 1.1.1.3.2.1 yamt of 2873 1.1.1.2 jruoho issues seen in the field, especially on machines with many cores: 2874 1.1.1.2 jruoho 2875 1.1.1.2 jruoho 1) Delete method children only upon the exit of the last thread, 2876 1.1.1.2 jruoho so as to not delete objects out from under other running threads 2877 1.1.1.2 jruoho (and possibly causing a fault.) 2878 1.1.1.2 jruoho 2) Set the "serialized" bit for the method only upon the exit of the 2879 1.1.1.2 jruoho Last thread, so as to not cause deadlock when running threads 2880 1.1.1.2 jruoho attempt to exit. 2881 1.1.1.2 jruoho 3) Cleanup the use of the AML "MethodFlags" and internal method flags 2882 1.1.1.2 jruoho so that there is no longer any confusion between the two. 2883 1.1.1.2 jruoho 2884 1.1.1.2 jruoho Lin Ming, Bob Moore. Reported by dana.myers (a] oracle.com. 2885 1.1.1.2 jruoho 2886 1.1.1.3.2.1 yamt Debugger: Now lock the namespace for duration of a namespace dump. 2887 1.1.1.3.2.1 yamt Prevents 2888 1.1.1.2 jruoho issues if the namespace is changing dynamically underneath the debugger. 2889 1.1.1.2 jruoho Especially affects temporary namespace nodes, since the debugger displays 2890 1.1.1.2 jruoho these also. 2891 1.1.1.2 jruoho 2892 1.1.1.2 jruoho Updated the ordering of include files. The ACPICA headers should appear 2893 1.1.1.3.2.1 yamt before any compiler-specific headers (stdio.h, etc.) so that acenv.h can 2894 1.1.1.3.2.1 yamt set 2895 1.1.1.3.2.1 yamt any necessary compiler-specific defines, etc. Affects the ACPI-related 2896 1.1.1.3.2.1 yamt tools 2897 1.1.1.2 jruoho and utilities. 2898 1.1.1.2 jruoho 2899 1.1.1.3.2.1 yamt Updated all ACPICA copyrights and signons to 2011.

ACPICA BZ 874. 3078 1.1.1.2 jruoho 3079 1.1.1.2 jruoho iASL: Allow certain "null" resource descriptors. Some BIOS code creates 3080 1.1.1.3.2.1 yamt descriptors that are mostly or all zeros, with the expectation that they 3081 1.1.1.3.2.1 yamt will 3082 1.1.1.3.2.1 yamt be filled in at runtime. iASL now allows this as long as there is a 3083 1.1.1.3.2.1 yamt "resource 3084 1.1.1.2 jruoho tag" (name) associated with the descriptor, which gives the ASL a handle 3085 1.1.1.2 jruoho needed to modify the descriptor. ACPICA BZ 873. 3086 1.1.1.2 jruoho 3087 1.1.1.3.2.1 yamt Added single-thread support to the generic Unix application OSL. 3088 1.1.1.3.2.1 yamt Primarily 3089 1.1.1.3.2.1 yamt for iASL support, this change removes the use of semaphores in the 3090 1.1.1.3.2.1 yamt single- 3091 1.1.1.2 jruoho threaded ACPICA tools/applications - increasing performance. The 3092 1.1.1.2 jruoho _MULTI_THREADED option was replaced by the (reverse) ACPI_SINGLE_THREADED 3093 1.1.1.2 jruoho option. ACPICA BZ 879. 3094 1.1.1.2 jruoho 3095 1.1.1.3.2.1 yamt AcpiExec: several fixes for the 64-bit version. Adds XSDT support and 3096 1.1.1.3.2.1 yamt support 3097 1.1.1.2 jruoho for 64-bit DSDT/FACS addresses in the FADT. Lin Ming. 3098 1.1.1.2 jruoho 3099 1.1.1.2 jruoho iASL: Moved all compiler messages to a new file, aslmessages.h. 3100 1.1.1.2 jruoho 3101 1.1.1.2 jruoho ---------------------------------------- 3102 1.1.1.2 jruoho 15 September 2010. Summary of changes for version 20100915: 3103 1.1.1.2 jruoho 3104 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 3105 1.1.1.2 jruoho 3106 1.1.1.3.2.1 yamt Removed the AcpiOsDerivePciId OSL interface. The various host 3107 1.1.1.3.2.1 yamt implementations 3108 1.1.1.2 jruoho of this function were not OS-dependent and are now obsolete and can be 3109 1.1.1.2 jruoho removed from all host OSLs. This function has been replaced by 3110 1.1.1.2 jruoho AcpiHwDerivePciId, which is now part of the ACPICA core code. 3111 1.1.1.2 jruoho AcpiHwDerivePciId has been implemented without recursion. Adds one new 3112 1.1.1.2 jruoho module, hwpci.c. ACPICA BZ 857. 3113 1.1.1.2 jruoho 3114 1.1.1.2 jruoho Implemented a dynamic repair for _HID and _CID strings. The following 3115 1.1.1.2 jruoho problems are now repaired at runtime: 1) Remove a leading asterisk in the 3116 1.1.1.2 jruoho string, and 2) the entire string is uppercased. Both repairs are in 3117 1.1.1.3.2.1 yamt accordance with the ACPI specification and will simplify host driver 3118 1.1.1.3.2.1 yamt code. 3119 1.1.1.2 jruoho ACPICA BZ 871. 3120 1.1.1.2 jruoho 3121 1.1.1.2 jruoho The ACPI_THREAD_ID type is no longer configurable, internally it is now 3122 1.1.1.3.2.1 yamt always UINT64. This simplifies the ACPICA code, especially any printf 3123 1.1.1.3.2.1 yamt output. 3124 1.1.1.2 jruoho UINT64 is the only common data type for all thread_id types across all 3125 1.1.1.3.2.1 yamt operating systems. It is now up to the host OSL to cast the native 3126 1.1.1.3.2.1 yamt thread_id 3127 1.1.1.3.2.1 yamt type to UINT64 before returning the value to ACPICA (via 3128 1.1.1.3.2.1 yamt AcpiOsGetThreadId). 3129 1.1.1.2 jruoho Lin Ming, Bob Moore. 3130 1.1.1.2 jruoho 3131 1.1.1.3.2.1 yamt Added the ACPI_INLINE type to enhance the ACPICA configuration. The 3132 1.1.1.3.2.1 yamt "inline" 3133 1.1.1.3.2.1 yamt keyword is not standard across compilers, and this type allows inline to 3134 1.1.1.3.2.1 yamt be 3135 1.1.1.2 jruoho configured on a per-compiler basis. Lin Ming. 3136 1.1.1.2 jruoho 3137 1.1.1.3.2.1 yamt Made the system global AcpiGbl_SystemAwakeAndRunning publically 3138 1.1.1.3.2.1 yamt available. 3139 1.1.1.3.2.1 yamt Added an extern for this boolean in acpixf.h. Some hosts utilize this 3140 1.1.1.3.2.1 yamt value 3141 1.1.1.2 jruoho during suspend/restore operations. ACPICA BZ 869. 3142 1.1.1.2 jruoho 3143 1.1.1.3.2.1 yamt All code that implements error/warning messages with the "ACPI:" prefix 3144 1.1.1.3.2.1 yamt has 3145 1.1.1.2 jruoho been moved to a new module, utxferror.c. 3146 1.1.1.2 jruoho 3147 1.1.1.3.2.1 yamt The UINT64_OVERLAY was moved to utmath.c, which is the only module where 3148 1.1.1.3.2.1 yamt it 3149 1.1.1.2 jruoho is used. ACPICA BZ 829. Lin Ming, Bob Moore. 3150 1.1.1.2 jruoho 3151 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3152 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3153 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3154 1.1.1.3.2.1 yamt has a 3155 1.1.1.2 jruoho much larger code and data size. 3156 1.1.1.2 jruoho 3157 1.1.1.2 jruoho Previous Release: 3158 1.1.1.2 jruoho Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 3159 1.1.1.2 jruoho Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 3160 1.1.1.2 jruoho Current Release: 3161 1.1.1.2 jruoho Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 3162 1.1.1.2 jruoho Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 3163 1.1.1.2 jruoho 3164 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 3165 1.1.1.2 jruoho 3166 1.1.1.3.2.1 yamt iASL/Disassembler: Write ACPI errors to stderr instead of the output 3167 1.1.1.3.2.1 yamt file. 3168 1.1.1.3.2.1 yamt This keeps the output files free of random error messages that may 3169 1.1.1.3.2.1 yamt originate 3170 1.1.1.3.2.1 yamt from within the namespace/interpreter code. Used this opportunity to 3171 1.1.1.3.2.1 yamt merge 3172 1.1.1.2 jruoho all ACPI:-style messages into a single new module, utxferror.c. ACPICA BZ 3173 1.1.1.2 jruoho 866. Lin Ming, Bob Moore. 3174 1.1.1.2 jruoho 3175 1.1.1.3.2.1 yamt Tools: update some printfs for ansi warnings on size_t. Handle width 3176 1.1.1.3.2.1 yamt change 3177 1.1.1.2 jruoho of size_t on 32-bit versus 64-bit generations. Lin Ming. 3178 1.1.1.2 jruoho 3179 1.1.1.2 jruoho ---------------------------------------- 3180 1.1.1.2 jruoho 06 August 2010. Summary of changes for version 20100806: 3181 1.1.1.2 jruoho 3182 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 3183 1.1.1.2 jruoho 3184 1.1.1.3.2.1 yamt Designed and implemented a new host interface to the _OSI support code. 3185 1.1.1.3.2.1 yamt This 3186 1.1.1.3.2.1 yamt will allow the host to dynamically add or remove multiple _OSI strings, 3187 1.1.1.3.2.1 yamt as 3188 1.1.1.3.2.1 yamt well as install an optional handler that is called for each _OSI 3189 1.1.1.3.2.1 yamt invocation. 3190 1.1.1.3.2.1 yamt Also added a new AML debugger command, 'osi' to display and modify the 3191 1.1.1.3.2.1 yamt global 3192 1.1.1.3.2.1 yamt _OSI string table, and test support in the AcpiExec utility. See the 3193 1.1.1.3.2.1 yamt ACPICA 3194 1.1.1.2 jruoho reference manual for full details. Lin Ming, Bob Moore. ACPICA BZ 836. 3195 1.1.1.2 jruoho New Functions: 3196 1.1.1.2 jruoho AcpiInstallInterface - Add an _OSI string. 3197 1.1.1.2 jruoho AcpiRemoveInterface - Delete an _OSI string. 3198 1.1.1.2 jruoho AcpiInstallInterfaceHandler - Install optional _OSI handler. 3199 1.1.1.2 jruoho Obsolete Functions: 3200 1.1.1.2 jruoho AcpiOsValidateInterface - no longer used. 3201 1.1.1.2 jruoho New Files: 3202 1.1.1.2 jruoho source/components/utilities/utosi.c 3203 1.1.1.2 jruoho 3204 1.1.1.2 jruoho Re-introduced the support to enable multi-byte transfers for Embedded 3205 1.1.1.3.2.1 yamt Controller (EC) operation regions. A reported problem was found to be a 3206 1.1.1.3.2.1 yamt bug 3207 1.1.1.3.2.1 yamt in the host OS, not in the multi-byte support. Previously, the maximum 3208 1.1.1.3.2.1 yamt data 3209 1.1.1.3.2.1 yamt size passed to the EC operation region handler was a single byte. There 3210 1.1.1.3.2.1 yamt are 3211 1.1.1.3.2.1 yamt often EC Fields larger than one byte that need to be transferred, and it 3212 1.1.1.3.2.1 yamt is 3213 1.1.1.3.2.1 yamt useful for the EC driver to lock these as a single transaction. This 3214 1.1.1.3.2.1 yamt change 3215 1.1.1.2 jruoho enables single transfers larger than 8 bits. This effectively changes the 3216 1.1.1.2 jruoho access to the EC space from ByteAcc to AnyAcc, and will probably require 3217 1.1.1.3.2.1 yamt changes to the host OS Embedded Controller driver to enable 16/32/64/256- 3218 1.1.1.3.2.1 yamt bit 3219 1.1.1.2 jruoho transfers in addition to 8-bit transfers. Alexey Starikovskiy, Lin Ming. 3220 1.1.1.2 jruoho 3221 1.1.1.2 jruoho Fixed a problem with the prototype for AcpiOsReadPciConfiguration. The 3222 1.1.1.2 jruoho prototype in acpiosxf.h had the output value pointer as a (void *). 3223 1.1.1.2 jruoho It should be a (UINT64 *). This may affect some host OSL code. 3224 1.1.1.2 jruoho 3225 1.1.1.3.2.1 yamt Fixed a couple problems with the recently modified Linux makefiles for 3226 1.1.1.3.2.1 yamt iASL 3227 1.1.1.2 jruoho and AcpiExec. These new makefiles place the generated object files in the 3228 1.1.1.3.2.1 yamt local directory so that there can be no collisions between the files that 3229 1.1.1.3.2.1 yamt are 3230 1.1.1.2 jruoho shared between them that are compiled with different options. 3231 1.1.1.2 jruoho 3232 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3233 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3234 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3235 1.1.1.3.2.1 yamt has a 3236 1.1.1.2 jruoho much larger code and data size. 3237 1.1.1.2 jruoho 3238 1.1.1.2 jruoho Previous Release: 3239 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 3240 1.1.1.2 jruoho Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 3241 1.1.1.2 jruoho Current Release: 3242 1.1.1.2 jruoho Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 3243 1.1.1.2 jruoho Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 3244 1.1.1.2 jruoho 3245 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 3246 1.1.1.2 jruoho 3247 1.1.1.3.2.1 yamt iASL/Disassembler: Added a new option (-da, "disassemble all") to load 3248 1.1.1.3.2.1 yamt the 3249 1.1.1.2 jruoho namespace from and disassemble an entire group of AML files. Useful for 3250 1.1.1.3.2.1 yamt loading all of the AML tables for a given machine (DSDT, SSDT1...SSDTn) 3251 1.1.1.3.2.1 yamt and 3252 1.1.1.2 jruoho disassembling with one simple command. ACPICA BZ 865. Lin Ming. 3253 1.1.1.2 jruoho 3254 1.1.1.3.2.1 yamt iASL: Allow multiple invocations of -e option. This change allows 3255 1.1.1.3.2.1 yamt multiple 3256 1.1.1.3.2.1 yamt uses of -e on the command line: "-e ssdt1.dat -e ssdt2.dat".

Summary of changes for version 20100702: 3262 1.1.1.2 jruoho 3263 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 3264 1.1.1.2 jruoho 3265 1.1.1.2 jruoho Implemented several updates to the recently added GPE reference count 3266 1.1.1.3.2.1 yamt support. The model for "wake" GPEs is changing to give the host OS 3267 1.1.1.3.2.1 yamt complete 3268 1.1.1.3.2.1 yamt control of these GPEs. Eventually, the ACPICA core will not execute any 3269 1.1.1.3.2.1 yamt _PRW 3270 1.1.1.3.2.1 yamt methods, since the host already must execute them. Also, additional 3271 1.1.1.3.2.1 yamt changes 3272 1.1.1.2 jruoho were made to help ensure that the reference counts are kept in proper 3273 1.1.1.2 jruoho synchronization with reality. Rafael J. Wysocki. 3274 1.1.1.2 jruoho 3275 1.1.1.2 jruoho 1) Ensure that GPEs are not enabled twice during initialization. 3276 1.1.1.2 jruoho 2) Ensure that GPE enable masks stay in sync with the reference count. 3277 1.1.1.2 jruoho 3) Do not inadvertently enable GPEs when writing GPE registers. 3278 1.1.1.2 jruoho 4) Remove the internal wake reference counter and add new AcpiGpeWakeup 3279 1.1.1.2 jruoho interface. This interface will set or clear individual GPEs for wakeup. 3280 1.1.1.3.2.1 yamt 5) Remove GpeType argument from AcpiEnable and AcpiDisable. These 3281 1.1.1.3.2.1 yamt interfaces 3282 1.1.1.2 jruoho are now used for "runtime" GPEs only. 3283 1.1.1.2 jruoho 3284 1.1.1.3.2.1 yamt Changed the behavior of the GPE install/remove handler interfaces. The 3285 1.1.1.3.2.1 yamt GPE 3286 1.1.1.3.2.1 yamt is 3287 1.1.1.3.2.1 yamt no longer disabled during this process, as it was found to cause problems 3288 1.1.1.3.2.1 yamt on 3289 1.1.1.2 jruoho some machines. Rafael J. Wysocki. 3290 1.1.1.2 jruoho 3291 1.1.1.2 jruoho Reverted a change introduced in version 20100528 to enable Embedded 3292 1.1.1.3.2.1 yamt Controller multi-byte transfers. This change was found to cause problems 3293 1.1.1.3.2.1 yamt with 3294 1.1.1.2 jruoho Index Fields and possibly Bank Fields. It will be reintroduced when these 3295 1.1.1.2 jruoho problems have been resolved. 3296 1.1.1.2 jruoho 3297 1.1.1.3.2.1 yamt Fixed a problem with references to Alias objects within Package Objects. 3298 1.1.1.3.2.1 yamt A 3299 1.1.1.2 jruoho reference to an Alias within the definition of a Package was not always 3300 1.1.1.3.2.1 yamt resolved properly. Aliases to objects like Processors, Thermal zones, 3301 1.1.1.3.2.1 yamt etc. 3302 1.1.1.3.2.1 yamt were resolved to the actual object instead of a reference to the object 3303 1.1.1.3.2.1 yamt as 3304 1.1.1.3.2.1 yamt it 3305 1.1.1.2 jruoho should be. Package objects are only allowed to contain integer, string, 3306 1.1.1.2 jruoho buffer, package, and reference objects. Redhat bugzilla 608648. 3307 1.1.1.2 jruoho 3308 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3309 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3310 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3311 1.1.1.3.2.1 yamt has a 3312 1.1.1.2 jruoho much larger code and data size. 3313 1.1.1.2 jruoho 3314 1.1.1.2 jruoho Previous Release: 3315 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 3316 1.1.1.2 jruoho Debug Version: 164.1K Code, 51.5K Data, 215.6K Total 3317 1.1.1.2 jruoho Current Release: 3318 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 3319 1.1.1.2 jruoho Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 3320 1.1.1.2 jruoho 3321 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 3322 1.1.1.2 jruoho 3323 1.1.1.2 jruoho iASL: Implemented a new compiler subsystem to allow definition and 3324 1.1.1.3.2.1 yamt compilation of the non-AML ACPI tables such as FADT, MADT, SRAT, etc. 3325 1.1.1.3.2.1 yamt These 3326 1.1.1.2 jruoho are called "ACPI Data Tables", and the new compiler is the "Data Table 3327 1.1.1.2 jruoho Compiler". This compiler is intended to simplify the existing error-prone 3328 1.1.1.2 jruoho process of creating these tables for the BIOS, as well as allowing the 3329 1.1.1.3.2.1 yamt disassembly, modification, recompilation, and override of existing ACPI 3330 1.1.1.3.2.1 yamt data 3331 1.1.1.2 jruoho tables. See the iASL User Guide for detailed information. 3332 1.1.1.2 jruoho 3333 1.1.1.3.2.1 yamt iASL: Implemented a new Template Generator option in support of the new 3334 1.1.1.3.2.1 yamt Data 3335 1.1.1.2 jruoho Table Compiler. This option will create examples of all known ACPI tables 3336 1.1.1.2 jruoho that can be used as the basis for table development. See the iASL 3337 1.1.1.2 jruoho documentation and the -T option. 3338 1.1.1.2 jruoho 3339 1.1.1.2 jruoho Disassembler and headers: Added support for the WDDT ACPI table (Watchdog 3340 1.1.1.2 jruoho Descriptor Table). 3341 1.1.1.2 jruoho 3342 1.1.1.2 jruoho Updated the Linux makefiles for iASL and AcpiExec to place the generated 3343 1.1.1.2 jruoho object files in the local directory so that there can be no collisions 3344 1.1.1.2 jruoho between the shared files between them that are generated with different 3345 1.1.1.2 jruoho options. 3346 1.1.1.2 jruoho 3347 1.1.1.3.2.1 yamt Added support for Mac OS X in the Unix OSL used for iASL and AcpiExec. 3348 1.1.1.3.2.1 yamt Use 3349 1.1.1.2 jruoho the #define __APPLE__ to enable this support. 3350 1.1.1.2 jruoho 3351 1.1.1.2 jruoho ---------------------------------------- 3352 1.1.1.2 jruoho 28 May 2010. Summary of changes for version 20100528: 3353 1.1.1.2 jruoho 3354 1.1 jruoho Note: The ACPI 4.0a specification was released on April 5, 2010 and is 3355 1.1 jruoho available at www.acpi.info. This is primarily an errata release. 3356 1.1 jruoho 3357 1.1 jruoho 1) ACPI CA Core Subsystem: 3358 1.1 jruoho 3359 1.1.1.3.2.1 yamt Undefined ACPI tables: We are looking for the definitions for the 3360 1.1.1.3.2.1 yamt following 3361 1.1 jruoho ACPI tables that have been seen in the field: ATKG, IEIT, GSCI. 3362 1.1 jruoho 3363 1.1.1.3.2.1 yamt Implemented support to enable multi-byte transfers for Embedded 3364 1.1.1.3.2.1 yamt Controller 3365 1.1.1.3.2.1 yamt (EC) operation regions. Previously, the maximum data size passed to the 3366 1.1.1.3.2.1 yamt EC 3367 1.1.1.3.2.1 yamt operation region handler was a single byte. There are often EC Fields 3368 1.1.1.3.2.1 yamt larger 3369 1.1.1.3.2.1 yamt than one byte that need to be transferred, and it is useful for the EC 3370 1.1.1.3.2.1 yamt driver 3371 1.1.1.3.2.1 yamt to lock these as a single transaction. This change enables single 3372 1.1.1.3.2.1 yamt transfers 3373 1.1.1.3.2.1 yamt larger than 8 bits. This effectively changes the access to the EC space 3374 1.1.1.3.2.1 yamt from 3375 1.1.1.3.2.1 yamt ByteAcc to AnyAcc, and will probably require changes to the host OS 3376 1.1.1.3.2.1 yamt Embedded 3377 1.1.1.3.2.1 yamt Controller driver to enable 16/32/64/256-bit transfers in addition to 8- 3378 1.1.1.3.2.1 yamt bit 3379 1.1 jruoho transfers. Alexey Starikovskiy, Lin Ming 3380 1.1 jruoho 3381 1.1.1.3.2.1 yamt Implemented a performance enhancement for namespace search and access. 3382 1.1.1.3.2.1 yamt This 3383 1.1.1.3.2.1 yamt change enhances the performance of namespace searches and walks by adding 3384 1.1.1.3.2.1 yamt a 3385 1.1.1.3.2.1 yamt backpointer to the parent in each namespace node. On large namespaces, 3386 1.1.1.3.2.1 yamt this 3387 1.1.1.3.2.1 yamt change can improve overall ACPI performance by up to 9X. Adding a pointer 3388 1.1.1.3.2.1 yamt to 3389 1.1.1.3.2.1 yamt each namespace node increases the overall size of the internal namespace 3390 1.1.1.3.2.1 yamt by 3391 1.1 jruoho about 5%, since each namespace entry usually consists of both a namespace 3392 1.1 jruoho node and an ACPI operand object. However, this is the first growth of the 3393 1.1 jruoho namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy. 3394 1.1 jruoho 3395 1.1.1.3.2.1 yamt Implemented a performance optimization that reduces the number of 3396 1.1.1.3.2.1 yamt namespace 3397 1.1.1.3.2.1 yamt walks. On control method exit, only walk the namespace if the method is 3398 1.1.1.3.2.1 yamt known 3399 1.1.1.3.2.1 yamt to have created namespace objects outside of its local scope. Previously, 3400 1.1.1.3.2.1 yamt the 3401 1.1.1.3.2.1 yamt entire namespace was traversed on each control method exit. This change 3402 1.1.1.3.2.1 yamt can 3403 1.1.1.3.2.1 yamt improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob 3404 1.1.1.3.2.1 yamt Moore. 3405 1.1 jruoho 3406 1.1.1.3.2.1 yamt Added support to truncate I/O addresses to 16 bits for Windows 3407 1.1.1.3.2.1 yamt compatibility. 3408 1.1 jruoho Some ASL code has been seen in the field that inadvertently has bits set 3409 1.1.1.3.2.1 yamt above bit 15. This feature is optional and is enabled if the BIOS 3410 1.1.1.3.2.1 yamt requests 3411 1.1 jruoho any Windows OSI strings. It can also be enabled by the host OS. Matthew 3412 1.1 jruoho Garrett, Bob Moore. 3413 1.1 jruoho 3414 1.1 jruoho Added support to limit the maximum time for the ASL Sleep() operator. To 3415 1.1 jruoho prevent accidental deep sleeps, limit the maximum time that Sleep() will 3416 1.1 jruoho actually sleep. Configurable, the default maximum is two seconds. ACPICA 3417 1.1 jruoho bugzilla 854. 3418 1.1 jruoho 3419 1.1.1.3.2.1 yamt Added run-time validation support for the _WDG and_WED Microsoft 3420 1.1.1.3.2.1 yamt predefined 3421 1.1.1.3.2.1 yamt methods. These objects are defined by "Windows Instrumentation", and are 3422 1.1.1.3.2.1 yamt not 3423 1.1 jruoho part of the ACPI spec. ACPICA BZ 860. 3424 1.1 jruoho 3425 1.1 jruoho Expanded all statistic counters used during namespace and device 3426 1.1.1.3.2.1 yamt initialization from 16 to 32 bits in order to support very large 3427 1.1.1.3.2.1 yamt namespaces. 3428 1.1 jruoho 3429 1.1.1.3.2.1 yamt Replaced all instances of %d in printf format specifiers with %u since 3430 1.1.1.3.2.1 yamt nearly 3431 1.1 jruoho all integers in ACPICA are unsigned. 3432 1.1 jruoho 3433 1.1.1.3.2.1 yamt Fixed the exception namestring for AE_WAKE_ONLY_GPE. Was incorrectly 3434 1.1.1.3.2.1 yamt returned 3435 1.1 jruoho as AE_NO_HANDLER. 3436 1.1 jruoho 3437 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3438 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3439 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3440 1.1.1.3.2.1 yamt has a 3441 1.1 jruoho much larger code and data size. 3442 1.1 jruoho 3443 1.1 jruoho Previous Release: 3444 1.1 jruoho Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total 3445 1.1 jruoho Debug Version: 164.2K Code, 51.5K Data, 215.7K Total 3446 1.1 jruoho Current Release: 3447 1.1 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 3448 1.1 jruoho Debug Version: 164.1K Code, 51.5K Data, 215.6K Total 3449 1.1 jruoho 3450 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3451 1.1 jruoho 3452 1.1 jruoho iASL: Added compiler support for the _WDG and_WED Microsoft predefined 3453 1.1.1.3.2.1 yamt methods. These objects are defined by "Windows Instrumentation", and are 3454 1.1.1.3.2.1 yamt not 3455 1.1 jruoho part of the ACPI spec. ACPICA BZ 860. 3456 1.1 jruoho 3457 1.1 jruoho AcpiExec: added option to disable the memory tracking mechanism. The -dt 3458 1.1 jruoho option will disable the tracking mechanism, which improves performance 3459 1.1 jruoho considerably. 3460 1.1 jruoho 3461 1.1 jruoho AcpiExec: Restructured the command line options into -d (disable) and -e 3462 1.1 jruoho (enable) options. 3463 1.1 jruoho 3464 1.1 jruoho ---------------------------------------- 3465 1.1 jruoho 28 April 2010. Summary of changes for version 20100428: 3466 1.1 jruoho 3467 1.1 jruoho 1) ACPI CA Core Subsystem: 3468 1.1 jruoho 3469 1.1 jruoho Implemented GPE support for dynamically loaded ACPI tables. For all GPEs, 3470 1.1.1.3.2.1 yamt including FADT-based and GPE Block Devices, execute any _PRW methods in 3471 1.1.1.3.2.1 yamt the 3472 1.1 jruoho new table, and process any _Lxx/_Exx GPE methods in the new table. Any 3473 1.1 jruoho runtime GPE that is referenced by an _Lxx/_Exx method in the new table is 3474 1.1 jruoho immediately enabled. Handles the FADT-defined GPEs as well as GPE Block 3475 1.1 jruoho Devices. Provides compatibility with other ACPI implementations. Two new 3476 1.1.1.3.2.1 yamt files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob 3477 1.1.1.3.2.1 yamt Moore. 3478 1.1 jruoho 3479 1.1.1.3.2.1 yamt Fixed a regression introduced in version 20100331 within the table 3480 1.1.1.3.2.1 yamt manager 3481 1.1.1.3.2.1 yamt where initial table loading could fail. This was introduced in the fix 3482 1.1.1.3.2.1 yamt for 3483 1.1.1.3.2.1 yamt AcpiReallocateRootTable. Also, renamed some of fields in the table 3484 1.1.1.3.2.1 yamt manager 3485 1.1 jruoho data structures to clarify their meaning and use. 3486 1.1 jruoho 3487 1.1 jruoho Fixed a possible allocation overrun during internal object copy in 3488 1.1.1.3.2.1 yamt AcpiUtCopySimpleObject. The original code did not correctly handle the 3489 1.1.1.3.2.1 yamt case 3490 1.1.1.3.2.1 yamt where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 3491 1.1.1.3.2.1 yamt 847. 3492 1.1 jruoho 3493 1.1 jruoho Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a 3494 1.1.1.3.2.1 yamt possible access beyond end-of-allocation. Also, now fully validate 3495 1.1.1.3.2.1 yamt descriptor 3496 1.1 jruoho (size and type) before output. Lin Ming, Bob Moore. ACPICA BZ 847 3497 1.1 jruoho 3498 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3499 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3500 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3501 1.1.1.3.2.1 yamt has a 3502 1.1 jruoho much larger code and data size. 3503 1.1 jruoho 3504 1.1 jruoho Previous Release: 3505 1.1 jruoho Non-Debug Version: 87.9K Code, 18.6K Data, 106.5K Total 3506 1.1 jruoho Debug Version: 163.5K Code, 51.3K Data, 214.8K Total 3507 1.1 jruoho Current Release: 3508 1.1 jruoho Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total 3509 1.1 jruoho Debug Version: 164.2K Code, 51.5K Data, 215.7K Total 3510 1.1 jruoho 3511 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3512 1.1 jruoho 3513 1.1 jruoho iASL: Implemented Min/Max/Len/Gran validation for address resource 3514 1.1.1.3.2.1 yamt descriptors. This change implements validation for the address fields 3515 1.1.1.3.2.1 yamt that 3516 1.1 jruoho are common to all address-type resource descriptors. These checks are 3517 1.1 jruoho implemented: Checks for valid Min/Max, length within the Min/Max window, 3518 1.1.1.3.2.1 yamt valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as 3519 1.1.1.3.2.1 yamt per 3520 1.1.1.3.2.1 yamt table 6-40 in the ACPI 4.0a specification. Also split the large 3521 1.1.1.3.2.1 yamt aslrestype1.c 3522 1.1 jruoho and aslrestype2.c files into five new files. ACPICA BZ 840. 3523 1.1 jruoho 3524 1.1.1.3.2.1 yamt iASL: Added support for the _Wxx predefined names. This support was 3525 1.1.1.3.2.1 yamt missing 3526 1.1 jruoho and these names were not recognized by the compiler as valid predefined 3527 1.1 jruoho names. ACPICA BZ 851. 3528 1.1 jruoho 3529 1.1.1.3.2.1 yamt iASL: Added an error for all predefined names that are defined to return 3530 1.1.1.3.2.1 yamt no 3531 1.1.1.3.2.1 yamt value and thus must be implemented as Control Methods. These include all 3532 1.1.1.3.2.1 yamt of 3533 1.1 jruoho the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous 3534 1.1 jruoho names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856. 3535 1.1 jruoho 3536 1.1.1.3.2.1 yamt iASL: Implemented the -ts option to emit hex AML data in ASL format, as 3537 1.1.1.3.2.1 yamt an 3538 1.1.1.3.2.1 yamt ASL Buffer. Allows ACPI tables to be easily included within ASL files, to 3539 1.1.1.3.2.1 yamt be 3540 1.1.1.3.2.1 yamt dynamically loaded via the Load() operator. Also cleaned up output for 3541 1.1.1.3.2.1 yamt the 3542 1.1.1.3.2.1 yamt - 3543 1.1 jruoho ta and -tc options. ACPICA BZ 853. 3544 1.1 jruoho 3545 1.1 jruoho Tests: Added a new file with examples of extended iASL error checking. 3546 1.1 jruoho Demonstrates the advanced error checking ability of the iASL compiler. 3547 1.1 jruoho Available at tests/misc/badcode.asl. 3548 1.1 jruoho 3549 1.1 jruoho ---------------------------------------- 3550 1.1 jruoho 31 March 2010. Summary of changes for version 20100331: 3551 1.1 jruoho 3552 1.1 jruoho 1) ACPI CA Core Subsystem: 3553 1.1 jruoho 3554 1.1.1.3.2.1 yamt Completed a major update for the GPE support in order to improve support 3555 1.1.1.3.2.1 yamt for 3556 1.1.1.3.2.1 yamt shared GPEs and to simplify both host OS and ACPICA code. Added a 3557 1.1.1.3.2.1 yamt reference 3558 1.1.1.3.2.1 yamt count mechanism to support shared GPEs that require multiple device 3559 1.1.1.3.2.1 yamt drivers. 3560 1.1 jruoho Several external interfaces have changed. One external interface has been 3561 1.1 jruoho removed. One new external interface was added. Most of the GPE external 3562 1.1 jruoho interfaces now use the GPE spinlock instead of the events mutex (and the 3563 1.1.1.3.2.1 yamt Flags parameter for many GPE interfaces has been removed.) See the 3564 1.1.1.3.2.1 yamt updated 3565 1.1.1.3.2.1 yamt ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, 3566 1.1.1.3.2.1 yamt Rafael 3567 1.1 jruoho Wysocki. ACPICA BZ 831. 3568 1.1 jruoho 3569 1.1 jruoho Changed: 3570 1.1 jruoho AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus 3571 1.1 jruoho Removed: 3572 1.1 jruoho AcpiSetGpeType 3573 1.1 jruoho New: 3574 1.1 jruoho AcpiSetGpe 3575 1.1 jruoho 3576 1.1.1.3.2.1 yamt Implemented write support for DataTable operation regions. These regions 3577 1.1.1.3.2.1 yamt are 3578 1.1.1.3.2.1 yamt defined via the DataTableRegion() operator. Previously, only read support 3579 1.1.1.3.2.1 yamt was 3580 1.1.1.3.2.1 yamt implemented. The ACPI specification allows DataTableRegions to be 3581 1.1.1.3.2.1 yamt read/write, 3582 1.1 jruoho however. 3583 1.1 jruoho 3584 1.1 jruoho Implemented a new subsystem option to force a copy of the DSDT to local 3585 1.1.1.3.2.1 yamt memory. Optionally copy the entire DSDT to local memory (instead of 3586 1.1.1.3.2.1 yamt simply 3587 1.1.1.3.2.1 yamt mapping it.) There are some (albeit very rare) BIOSs that corrupt or 3588 1.1.1.3.2.1 yamt replace 3589 1.1.1.3.2.1 yamt the original DSDT, creating the need for this option. Default is FALSE, 3590 1.1.1.3.2.1 yamt do 3591 1.1 jruoho not copy the DSDT. 3592 1.1 jruoho 3593 1.1 jruoho Implemented detection of a corrupted or replaced DSDT. This change adds 3594 1.1.1.3.2.1 yamt support to detect a DSDT that has been corrupted and/or replaced from 3595 1.1.1.3.2.1 yamt outside 3596 1.1.1.3.2.1 yamt the OS (by firmware). This is typically catastrophic for the system, but 3597 1.1.1.3.2.1 yamt has 3598 1.1 jruoho been seen on some machines. Once this problem has been detected, the DSDT 3599 1.1 jruoho copy option can be enabled via system configuration. Lin Ming, Bob Moore. 3600 1.1 jruoho 3601 1.1.1.3.2.1 yamt Fixed two problems with AcpiReallocateRootTable during the root table 3602 1.1.1.3.2.1 yamt copy. 3603 1.1 jruoho When copying the root table to the new allocation, the length used was 3604 1.1.1.3.2.1 yamt incorrect. The new size was used instead of the current table size, 3605 1.1.1.3.2.1 yamt meaning 3606 1.1.1.3.2.1 yamt too much data was copied. Also, the count of available slots for ACPI 3607 1.1.1.3.2.1 yamt tables 3608 1.1 jruoho was not set correctly. Alexey Starikovskiy, Bob Moore. 3609 1.1 jruoho 3610 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3611 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3612 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3613 1.1.1.3.2.1 yamt has a 3614 1.1 jruoho much larger code and data size. 3615 1.1 jruoho 3616 1.1 jruoho Previous Release: 3617 1.1 jruoho Non-Debug Version: 87.5K Code, 18.4K Data, 105.9K Total 3618 1.1 jruoho Debug Version: 163.4K Code, 51.1K Data, 214.5K Total 3619 1.1 jruoho Current Release: 3620 1.1 jruoho Non-Debug Version: 87.9K Code, 18.6K Data, 106.5K Total 3621 1.1 jruoho Debug Version: 163.5K Code, 51.3K Data, 214.8K Total 3622 1.1 jruoho 3623 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3624 1.1 jruoho 3625 1.1 jruoho iASL: Implement limited typechecking for values returned from predefined 3626 1.1 jruoho control methods. The type of any returned static (unnamed) object is now 3627 1.1 jruoho validated. For example, Return(1). ACPICA BZ 786. 3628 1.1 jruoho 3629 1.1.1.3.2.1 yamt iASL: Fixed a predefined name object verification regression. Fixes a 3630 1.1.1.3.2.1 yamt problem 3631 1.1 jruoho introduced in version 20100304. An error is incorrectly generated if a 3632 1.1 jruoho predefined name is declared as a static named object with a value defined 3633 1.1 jruoho using the keywords "Zero", "One", or "Ones". Lin Ming. 3634 1.1 jruoho 3635 1.1.1.3.2.1 yamt iASL: Added Windows 7 support for the -g option (get local ACPI tables) 3636 1.1.1.3.2.1 yamt by 3637 1.1 jruoho reducing the requested registry access rights. ACPICA BZ 842. 3638 1.1 jruoho 3639 1.1.1.3.2.1 yamt Disassembler: fixed a possible fault when generating External() 3640 1.1.1.3.2.1 yamt statements. 3641 1.1.1.3.2.1 yamt Introduced in commit ae7d6fd: Properly handle externals with parent- 3642 1.1.1.3.2.1 yamt prefix 3643 1.1 jruoho (carat). Fixes a string length allocation calculation. Lin Ming. 3644 1.1 jruoho 3645 1.1 jruoho ---------------------------------------- 3646 1.1 jruoho 04 March 2010. Summary of changes for version 20100304: 3647 1.1 jruoho 3648 1.1 jruoho 1) ACPI CA Core Subsystem: 3649 1.1 jruoho 3650 1.1 jruoho Fixed a possible problem with the AML Mutex handling function 3651 1.1 jruoho AcpiExReleaseMutex where the function could fault under the very rare 3652 1.1.1.3.2.1 yamt condition when the interpreter has blocked, the interpreter lock is 3653 1.1.1.3.2.1 yamt released, 3654 1.1 jruoho the interpreter is then reentered via the same thread, and attempts to 3655 1.1.1.3.2.1 yamt acquire an AML mutex that was previously acquired. FreeBSD report 140979. 3656 1.1.1.3.2.1 yamt Lin 3657 1.1 jruoho Ming. 3658 1.1 jruoho 3659 1.1 jruoho Implemented additional configuration support for the AML "Debug Object". 3660 1.1 jruoho Output from the debug object can now be enabled via a global variable, 3661 1.1.1.3.2.1 yamt AcpiGbl_EnableAmlDebugObject. This will assist with remote machine 3662 1.1.1.3.2.1 yamt debugging. 3663 1.1.1.3.2.1 yamt This debug output is now available in the release version of ACPICA 3664 1.1.1.3.2.1 yamt instead 3665 1.1.1.3.2.1 yamt of just the debug version. Also, the entire debug output module can now 3666 1.1.1.3.2.1 yamt be 3667 1.1 jruoho configured out of the ACPICA build if desired. One new file added, 3668 1.1 jruoho executer/exdebug.c. Lin Ming, Bob Moore. 3669 1.1 jruoho 3670 1.1 jruoho Added header support for the ACPI MCHI table (Management Controller Host 3671 1.1.1.3.2.1 yamt Interface Table). This table was added in ACPI 4.0, but the defining 3672 1.1.1.3.2.1 yamt document 3673 1.1 jruoho has only recently become available. 3674 1.1 jruoho 3675 1.1.1.3.2.1 yamt Standardized output of integer values for ACPICA warnings/errors. Always 3676 1.1.1.3.2.1 yamt use 3677 1.1.1.3.2.1 yamt 0x prefix for hex output, always use %u for unsigned integer decimal 3678 1.1.1.3.2.1 yamt output. 3679 1.1.1.3.2.1 yamt Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 3680 1.1.1.3.2.1 yamt 400 3681 1.1 jruoho invocations.) These invocations were converted from the original 3682 1.1 jruoho ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835. 3683 1.1 jruoho 3684 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3685 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3686 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3687 1.1.1.3.2.1 yamt has a 3688 1.1 jruoho much larger code and data size. 3689 1.1 jruoho 3690 1.1 jruoho Previous Release: 3691 1.1 jruoho Non-Debug Version: 87.1K Code, 18.0K Data, 105.1K Total 3692 1.1 jruoho Debug Version: 163.5K Code, 50.9K Data, 214.4K Total 3693 1.1 jruoho Current Release: 3694 1.1 jruoho Non-Debug Version: 87.5K Code, 18.4K Data, 105.9K Total 3695 1.1 jruoho Debug Version: 163.4K Code, 51.1K Data, 214.5K Total 3696 1.1 jruoho 3697 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3698 1.1 jruoho 3699 1.1 jruoho iASL: Implemented typechecking support for static (non-control method) 3700 1.1 jruoho predefined named objects that are declared with the Name() operator. For 3701 1.1 jruoho example, the type of this object is now validated to be of type Integer: 3702 1.1.1.3.2.1 yamt Name(_BBN, 1). This change migrates the compiler to using the core 3703 1.1.1.3.2.1 yamt predefined 3704 1.1 jruoho name table instead of maintaining a local version. Added a new file, 3705 1.1 jruoho aslpredef.c. ACPICA BZ 832. 3706 1.1 jruoho 3707 1.1 jruoho Disassembler: Added support for the ACPI 4.0 MCHI table. 3708 1.1 jruoho 3709 1.1 jruoho ---------------------------------------- 3710 1.1 jruoho 21 January 2010. Summary of changes for version 20100121: 3711 1.1 jruoho 3712 1.1 jruoho 1) ACPI CA Core Subsystem: 3713 1.1 jruoho 3714 1.1 jruoho Added the 2010 copyright to all module headers and signons. This affects 3715 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, the 3716 1.1 jruoho tools/utilities, and the test suites. 3717 1.1 jruoho 3718 1.1.1.3.2.1 yamt Implemented a change to the AcpiGetDevices interface to eliminate 3719 1.1.1.3.2.1 yamt unnecessary 3720 1.1 jruoho invocations of the _STA method. In the case where a specific _HID is 3721 1.1 jruoho requested, do not run _STA until a _HID match is found. This eliminates 3722 1.1.1.3.2.1 yamt potentially dozens of _STA calls during a search for a particular 3723 1.1.1.3.2.1 yamt device/HID, 3724 1.1 jruoho which in turn can improve boot times. ACPICA BZ 828. Lin Ming. 3725 1.1 jruoho 3726 1.1.1.3.2.1 yamt Implemented an additional repair for predefined method return values. 3727 1.1.1.3.2.1 yamt Attempt 3728 1.1.1.3.2.1 yamt to repair unexpected NULL elements within returned Package objects. 3729 1.1.1.3.2.1 yamt Create 3730 1.1.1.3.2.1 yamt an 3731 1.1.1.3.2.1 yamt Integer of value zero, a NULL String, or a zero-length Buffer as 3732 1.1.1.3.2.1 yamt appropriate. 3733 1.1 jruoho ACPICA BZ 818. Lin Ming, Bob Moore. 3734 1.1 jruoho 3735 1.1.1.3.2.1 yamt Removed the obsolete ACPI_INTEGER data type. This type was introduced as 3736 1.1.1.3.2.1 yamt the 3737 1.1.1.3.2.1 yamt code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 3738 1.1.1.3.2.1 yamt (with 3739 1.1.1.3.2.1 yamt 64-bit AML integers). It is now obsolete and this change removes it from 3740 1.1.1.3.2.1 yamt the 3741 1.1.1.3.2.1 yamt ACPICA code base, replaced by UINT64. The original typedef has been 3742 1.1.1.3.2.1 yamt retained 3743 1.1.1.3.2.1 yamt for now for compatibility with existing device driver code. ACPICA BZ 3744 1.1.1.3.2.1 yamt 824. 3745 1.1 jruoho 3746 1.1.1.3.2.1 yamt Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field 3747 1.1.1.3.2.1 yamt in 3748 1.1 jruoho the parse tree object. 3749 1.1 jruoho 3750 1.1.1.3.2.1 yamt Added additional warning options for the gcc-4 generation. Updated the 3751 1.1.1.3.2.1 yamt source 3752 1.1.1.3.2.1 yamt accordingly. This includes some code restructuring to eliminate 3753 1.1.1.3.2.1 yamt unreachable 3754 1.1.1.3.2.1 yamt code, elimination of some gotos, elimination of unused return values, 3755 1.1.1.3.2.1 yamt some 3756 1.1 jruoho additional casting, and removal of redundant declarations. 3757 1.1 jruoho 3758 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3759 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3760 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3761 1.1.1.3.2.1 yamt has a 3762 1.1 jruoho much larger code and data size. 3763 1.1 jruoho 3764 1.1 jruoho Previous Release: 3765 1.1 jruoho Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 3766 1.1 jruoho Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 3767 1.1 jruoho Current Release: 3768 1.1 jruoho Non-Debug Version: 87.1K Code, 18.0K Data, 105.1K Total 3769 1.1 jruoho Debug Version: 163.5K Code, 50.9K Data, 214.4K Total 3770 1.1 jruoho 3771 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3772 1.1 jruoho 3773 1.1 jruoho No functional changes for this release. 3774 1.1 jruoho 3775 1.1 jruoho ---------------------------------------- 3776 1.1 jruoho 14 December 2009. Summary of changes for version 20091214: 3777 1.1 jruoho 3778 1.1 jruoho 1) ACPI CA Core Subsystem: 3779 1.1 jruoho 3780 1.1.1.3.2.1 yamt Enhanced automatic data type conversions for predefined name repairs. 3781 1.1.1.3.2.1 yamt This 3782 1.1.1.3.2.1 yamt change expands the automatic repairs/conversions for predefined name 3783 1.1.1.3.2.1 yamt return 3784 1.1.1.3.2.1 yamt values to make Integers, Strings, and Buffers fully interchangeable. 3785 1.1.1.3.2.1 yamt Also, 3786 1.1.1.3.2.1 yamt a 3787 1.1.1.3.2.1 yamt Buffer can be converted to a Package of Integers if necessary. The 3788 1.1.1.3.2.1 yamt nsrepair.c 3789 1.1 jruoho module was completely restructured. Lin Ming, Bob Moore. 3790 1.1 jruoho 3791 1.1.1.3.2.1 yamt Implemented automatic removal of null package elements during predefined 3792 1.1.1.3.2.1 yamt name 3793 1.1 jruoho repairs. This change will automatically remove embedded and trailing NULL 3794 1.1.1.3.2.1 yamt package elements from returned package objects that are defined to 3795 1.1.1.3.2.1 yamt contain 3796 1.1.1.3.2.1 yamt a 3797 1.1.1.3.2.1 yamt variable number of sub-packages. The driver is then presented with a 3798 1.1.1.3.2.1 yamt package 3799 1.1 jruoho with no null elements to deal with. ACPICA BZ 819. 3800 1.1 jruoho 3801 1.1 jruoho Implemented a repair for the predefined _FDE and _GTM names. The expected 3802 1.1.1.3.2.1 yamt return value for both names is a Buffer of 5 DWORDs. This repair fixes 3803 1.1.1.3.2.1 yamt two 3804 1.1.1.3.2.1 yamt possible problems (both seen in the field), where a package of integers 3805 1.1.1.3.2.1 yamt is 3806 1.1.1.3.2.1 yamt returned, or a buffer of BYTEs is returned. With assistance from Jung-uk 3807 1.1.1.3.2.1 yamt Kim. 3808 1.1.1.3.2.1 yamt 3809 1.1.1.3.2.1 yamt Implemented additional module-level code support. This change will 3810 1.1.1.3.2.1 yamt properly 3811 1.1.1.3.2.1 yamt execute module-level code that is not at the root of the namespace (under 3812 1.1.1.3.2.1 yamt a 3813 1.1.1.3.2.1 yamt Device object, etc.). Now executes the code within the current scope 3814 1.1.1.3.2.1 yamt instead 3815 1.1 jruoho of the root. ACPICA BZ 762. Lin Ming. 3816 1.1 jruoho 3817 1.1.1.3.2.1 yamt Fixed possible mutex acquisition errors when running _REG methods. Fixes 3818 1.1.1.3.2.1 yamt a 3819 1.1.1.3.2.1 yamt problem where mutex errors can occur when running a _REG method that is 3820 1.1.1.3.2.1 yamt in 3821 1.1.1.3.2.1 yamt the same scope as a method-defined operation region or an operation 3822 1.1.1.3.2.1 yamt region 3823 1.1.1.3.2.1 yamt under a module-level IF block. This type of code is rare, so the problem 3824 1.1.1.3.2.1 yamt has 3825 1.1 jruoho not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore. 3826 1.1 jruoho 3827 1.1.1.3.2.1 yamt Fixed a possible memory leak during module-level code execution. An 3828 1.1.1.3.2.1 yamt object 3829 1.1 jruoho could be leaked for each block of executed module-level code if the 3830 1.1.1.3.2.1 yamt interpreter slack mode is enabled This change deletes any implicitly 3831 1.1.1.3.2.1 yamt returned 3832 1.1 jruoho object from the module-level code block. Lin Ming. 3833 1.1 jruoho 3834 1.1.1.3.2.1 yamt Removed messages for successful predefined repair(s). The repair 3835 1.1.1.3.2.1 yamt mechanism 3836 1.1.1.3.2.1 yamt was considered too wordy. Now, messages are only unconditionally emitted 3837 1.1.1.3.2.1 yamt if 3838 1.1 jruoho the return object cannot be repaired. Existing messages for successful 3839 1.1.1.3.2.1 yamt repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 3840 1.1.1.3.2.1 yamt 827. 3841 1.1 jruoho 3842 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3843 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3844 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3845 1.1.1.3.2.1 yamt has a 3846 1.1 jruoho much larger code and data size. 3847 1.1 jruoho 3848 1.1 jruoho Previous Release: 3849 1.1 jruoho Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 3850 1.1 jruoho Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 3851 1.1 jruoho Current Release: 3852 1.1 jruoho Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 3853 1.1 jruoho Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 3854 1.1 jruoho 3855 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3856 1.1 jruoho 3857 1.1.1.3.2.1 yamt iASL: Fixed a regression introduced in 20091112 where intermediate .SRC 3858 1.1.1.3.2.1 yamt files 3859 1.1 jruoho were no longer automatically removed at the termination of the compile. 3860 1.1 jruoho 3861 1.1 jruoho acpiexec: Implemented the -f option to specify default region fill value. 3862 1.1 jruoho This option specifies the value used to initialize buffers that simulate 3863 1.1.1.3.2.1 yamt operation regions. Default value is zero. Useful for debugging problems 3864 1.1.1.3.2.1 yamt that 3865 1.1 jruoho depend on a specific initial value for a region or field. 3866 1.1 jruoho 3867 1.1 jruoho ---------------------------------------- 3868 1.1 jruoho 12 November 2009. Summary of changes for version 20091112: 3869 1.1 jruoho 3870 1.1 jruoho 1) ACPI CA Core Subsystem: 3871 1.1 jruoho 3872 1.1 jruoho Implemented a post-order callback to AcpiWalkNamespace. The existing 3873 1.1 jruoho interface only has a pre-order callback. This change adds an additional 3874 1.1.1.3.2.1 yamt parameter for a post-order callback which will be more useful for bus 3875 1.1.1.3.2.1 yamt scans. 3876 1.1 jruoho ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference. 3877 1.1 jruoho 3878 1.1 jruoho Modified the behavior of the operation region memory mapping cache for 3879 1.1.1.3.2.1 yamt SystemMemory. Ensure that the memory mappings created for operation 3880 1.1.1.3.2.1 yamt regions 3881 1.1 jruoho do not cross 4K page boundaries. Crossing a page boundary while mapping 3882 1.1.1.3.2.1 yamt regions can cause kernel warnings on some hosts if the pages have 3883 1.1.1.3.2.1 yamt different 3884 1.1.1.3.2.1 yamt attributes. Such regions are probably BIOS bugs, and this is the 3885 1.1.1.3.2.1 yamt workaround. 3886 1.1 jruoho Linux BZ 14445. Lin Ming. 3887 1.1 jruoho 3888 1.1 jruoho Implemented an automatic repair for predefined methods that must return 3889 1.1.1.3.2.1 yamt sorted lists. This change will repair (by sorting) packages returned by 3890 1.1.1.3.2.1 yamt _ALR, 3891 1.1.1.3.2.1 yamt _PSS, and _TSS. Drivers can now assume that the packages are correctly 3892 1.1.1.3.2.1 yamt sorted 3893 1.1 jruoho and do not contain NULL package elements. Adds one new file, 3894 1.1 jruoho namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore. 3895 1.1 jruoho 3896 1.1.1.3.2.1 yamt Fixed a possible fault during predefined name validation if a return 3897 1.1.1.3.2.1 yamt Package 3898 1.1 jruoho object contains NULL elements. Also adds a warning if a NULL element is 3899 1.1.1.3.2.1 yamt followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement 3900 1.1.1.3.2.1 yamt may 3901 1.1 jruoho include repair or removal of all such NULL elements where possible. 3902 1.1 jruoho 3903 1.1.1.3.2.1 yamt Implemented additional module-level executable AML code support. This 3904 1.1.1.3.2.1 yamt change 3905 1.1 jruoho will execute module-level code that is not at the root of the namespace 3906 1.1.1.3.2.1 yamt (under a Device object, etc.) at table load time. Module-level executable 3907 1.1.1.3.2.1 yamt AML 3908 1.1 jruoho code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming. 3909 1.1 jruoho 3910 1.1.1.3.2.1 yamt Implemented a new internal function to create Integer objects. This 3911 1.1.1.3.2.1 yamt function 3912 1.1 jruoho simplifies miscellaneous object creation code. ACPICA BZ 823. 3913 1.1 jruoho 3914 1.1.1.3.2.1 yamt Reduced the severity of predefined repair messages, Warning to Info. 3915 1.1.1.3.2.1 yamt Since 3916 1.1.1.3.2.1 yamt the object was successfully repaired, a warning is too severe. Reduced to 3917 1.1.1.3.2.1 yamt an 3918 1.1.1.3.2.1 yamt info message for now. These messages may eventually be changed to debug- 3919 1.1.1.3.2.1 yamt only. 3920 1.1 jruoho ACPICA BZ 812. 3921 1.1 jruoho 3922 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3923 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3924 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3925 1.1.1.3.2.1 yamt has a 3926 1.1 jruoho much larger code and data size. 3927 1.1 jruoho 3928 1.1 jruoho Previous Release: 3929 1.1 jruoho Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total 3930 1.1 jruoho Debug Version: 161.8K Code, 50.6K Data, 212.4K Total 3931 1.1 jruoho Current Release: 3932 1.1 jruoho Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 3933 1.1 jruoho Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 3934 1.1 jruoho 3935 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3936 1.1 jruoho 3937 1.1.1.3.2.1 yamt iASL: Implemented Switch() with While(1) so that Break works correctly. 3938 1.1.1.3.2.1 yamt This 3939 1.1.1.3.2.1 yamt change correctly implements the Switch operator with a surrounding 3940 1.1.1.3.2.1 yamt While(1) 3941 1.1 jruoho so that the Break operator works as expected. ACPICA BZ 461. Lin Ming. 3942 1.1 jruoho 3943 1.1.1.3.2.1 yamt iASL: Added a message if a package initializer list is shorter than 3944 1.1.1.3.2.1 yamt package 3945 1.1.1.3.2.1 yamt length. Adds a new remark for a Package() declaration if an initializer 3946 1.1.1.3.2.1 yamt list 3947 1.1 jruoho exists, but is shorter than the declared length of the package. Although 3948 1.1 jruoho technically legal, this is probably a coding error and it is seen in the 3949 1.1 jruoho field. ACPICA BZ 815. Lin Ming, Bob Moore. 3950 1.1 jruoho 3951 1.1.1.3.2.1 yamt iASL: Fixed a problem where the compiler could fault after the maximum 3952 1.1.1.3.2.1 yamt number 3953 1.1 jruoho of errors was reached (200). 3954 1.1 jruoho 3955 1.1.1.3.2.1 yamt acpixtract: Fixed a possible warning for pointer cast if the compiler 3956 1.1.1.3.2.1 yamt warning 3957 1.1 jruoho level set very high. 3958 1.1 jruoho 3959 1.1 jruoho ---------------------------------------- 3960 1.1 jruoho 13 October 2009. Summary of changes for version 20091013: 3961 1.1 jruoho 3962 1.1 jruoho 1) ACPI CA Core Subsystem: 3963 1.1 jruoho 3964 1.1.1.3.2.1 yamt Fixed a problem where an Operation Region _REG method could be executed 3965 1.1.1.3.2.1 yamt more 3966 1.1.1.3.2.1 yamt than once. If a custom address space handler is installed by the host 3967 1.1.1.3.2.1 yamt before 3968 1.1.1.3.2.1 yamt the "initialize operation regions" phase of the ACPICA initialization, 3969 1.1.1.3.2.1 yamt any 3970 1.1 jruoho _REG methods for that address space could be executed twice. This change 3971 1.1 jruoho fixes the problem. ACPICA BZ 427. Lin Ming. 3972 1.1 jruoho 3973 1.1 jruoho Fixed a possible memory leak for the Scope() ASL operator. When the exact 3974 1.1 jruoho invocation of "Scope(\)" is executed (change scope to root), one internal 3975 1.1 jruoho operand object was leaked. Lin Ming. 3976 1.1 jruoho 3977 1.1 jruoho Implemented a run-time repair for the _MAT predefined method. If the _MAT 3978 1.1 jruoho return value is defined as a Field object in the AML, and the field 3979 1.1.1.3.2.1 yamt size is less than or equal to the default width of an integer (32 or 3980 1.1.1.3.2.1 yamt 64),_MAT 3981 1.1 jruoho can incorrectly return an Integer instead of a Buffer. ACPICA now 3982 1.1 jruoho automatically repairs this problem. ACPICA BZ 810. 3983 1.1 jruoho 3984 1.1.1.3.2.1 yamt Implemented a run-time repair for the _BIF and _BIX predefined methods. 3985 1.1.1.3.2.1 yamt The 3986 1.1 jruoho "OEM Information" field is often incorrectly returned as an Integer with 3987 1.1.1.3.2.1 yamt value zero if the field is not supported by the platform. This is due to 3988 1.1.1.3.2.1 yamt an 3989 1.1 jruoho ambiguity in the ACPI specification. The field should always be a string. 3990 1.1 jruoho ACPICA now automatically repairs this problem by returning a NULL string 3991 1.1 jruoho within the returned Package. ACPICA BZ 807. 3992 1.1 jruoho 3993 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3994 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3995 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 3996 1.1.1.3.2.1 yamt has a 3997 1.1 jruoho much larger code and data size. 3998 1.1 jruoho 3999 1.1 jruoho Previous Release: 4000 1.1 jruoho Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total 4001 1.1 jruoho Debug Version: 161.7K Code, 50.9K Data, 212.6K Total 4002 1.1 jruoho Current Release: 4003 1.1 jruoho Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total 4004 1.1 jruoho Debug Version: 161.8K Code, 50.6K Data, 212.4K Total 4005 1.1 jruoho 4006 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4007 1.1 jruoho 4008 1.1 jruoho Disassembler: Fixed a problem where references to external symbols that 4009 1.1.1.3.2.1 yamt contained one or more parent-prefixes (carats) were not handled 4010 1.1.1.3.2.1 yamt correctly, 4011 1.1 jruoho possibly causing a fault. ACPICA BZ 806. Lin Ming. 4012 1.1 jruoho 4013 1.1 jruoho Disassembler: Restructured the code so that all functions that handle 4014 1.1 jruoho external symbols are in a single module. One new file is added, 4015 1.1 jruoho common/dmextern.c. 4016 1.1 jruoho 4017 1.1 jruoho AML Debugger: Added a max count argument for the Batch command (which 4018 1.1 jruoho executes multiple predefined methods within the namespace.) 4019 1.1 jruoho 4020 1.1 jruoho iASL: Updated the compiler documentation (User Reference.) Available at 4021 1.1 jruoho http://www.acpica.org/documentation/. ACPICA BZ 750. 4022 1.1 jruoho 4023 1.1 jruoho AcpiXtract: Updated for Lint and other formatting changes. Close all open 4024 1.1 jruoho files. 4025 1.1 jruoho 4026 1.1 jruoho ---------------------------------------- 4027 1.1 jruoho 03 September 2009. Summary of changes for version 20090903: 4028 1.1 jruoho 4029 1.1 jruoho 1) ACPI CA Core Subsystem: 4030 1.1 jruoho 4031 1.1 jruoho For Windows Vista compatibility, added the automatic execution of an _INI 4032 1.1 jruoho method located at the namespace root (\_INI). This method is executed at 4033 1.1.1.3.2.1 yamt table load time. This support is in addition to the automatic execution 4034 1.1.1.3.2.1 yamt of 4035 1.1 jruoho \_SB._INI. Lin Ming. 4036 1.1 jruoho 4037 1.1.1.3.2.1 yamt Fixed a possible memory leak in the interpreter for AML package objects 4038 1.1.1.3.2.1 yamt if 4039 1.1.1.3.2.1 yamt the package initializer list is longer than the defined size of the 4040 1.1.1.3.2.1 yamt package. 4041 1.1.1.3.2.1 yamt This apparently can only happen if the BIOS changes the package size on 4042 1.1.1.3.2.1 yamt the 4043 1.1 jruoho fly (seen in a _PSS object), as ASL compilers do not allow this. The 4044 1.1.1.3.2.1 yamt interpreter will truncate the package to the defined size (and issue an 4045 1.1.1.3.2.1 yamt error 4046 1.1.1.3.2.1 yamt message), but previously could leave the extra objects undeleted if they 4047 1.1.1.3.2.1 yamt were 4048 1.1.1.3.2.1 yamt pre-created during the argument processing (such is the case if the 4049 1.1.1.3.2.1 yamt package 4050 1.1 jruoho consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805. 4051 1.1 jruoho 4052 1.1 jruoho Fixed a problem seen when a Buffer or String is stored to itself via ASL. 4053 1.1.1.3.2.1 yamt This has been reported in the field. Previously, ACPICA would zero out 4054 1.1.1.3.2.1 yamt the 4055 1.1 jruoho buffer/string. Now, the operation is treated as a noop. Provides Windows 4056 1.1 jruoho compatibility. ACPICA BZ 803. Lin Ming. 4057 1.1 jruoho 4058 1.1 jruoho Removed an extraneous error message for ASL constructs of the form 4059 1.1.1.3.2.1 yamt Store(LocalX,LocalX) when LocalX is uninitialized. These curious 4060 1.1.1.3.2.1 yamt statements 4061 1.1.1.3.2.1 yamt are seen in many BIOSs and are once again treated as NOOPs and no error 4062 1.1.1.3.2.1 yamt is 4063 1.1 jruoho emitted when they are encountered. ACPICA BZ 785. 4064 1.1 jruoho 4065 1.1 jruoho Fixed an extraneous warning message if a _DSM reserved method returns a 4066 1.1 jruoho Package object. _DSM can return any type of object, so validation on the 4067 1.1 jruoho return type cannot be performed. ACPICA BZ 802. 4068 1.1 jruoho 4069 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4070 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4071 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4072 1.1.1.3.2.1 yamt has a 4073 1.1 jruoho much larger code and data size. 4074 1.1 jruoho 4075 1.1 jruoho Previous Release: 4076 1.1 jruoho Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total 4077 1.1 jruoho Debug Version: 161.6K Code, 50.9K Data, 212.5K Total 4078 1.1 jruoho Current Release: 4079 1.1 jruoho Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total 4080 1.1 jruoho Debug Version: 161.7K Code, 50.9K Data, 212.6K Total 4081 1.1 jruoho 4082 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4083 1.1 jruoho 4084 1.1 jruoho iASL: Fixed a problem with the use of the Alias operator and Resource 4085 1.1 jruoho Templates. The correct alias is now constructed and no error is emitted. 4086 1.1 jruoho ACPICA BZ 738. 4087 1.1 jruoho 4088 1.1.1.3.2.1 yamt iASL: Implemented the -I option to specify additional search directories 4089 1.1.1.3.2.1 yamt for 4090 1.1 jruoho include files. Allows multiple additional search paths for include files. 4091 1.1.1.3.2.1 yamt Directories are searched in the order specified on the command line 4092 1.1.1.3.2.1 yamt (after 4093 1.1 jruoho the local directory is searched.) ACPICA BZ 800. 4094 1.1 jruoho 4095 1.1 jruoho iASL: Fixed a problem where the full pathname for include files was not 4096 1.1 jruoho emitted for warnings/errors. This caused the IDE support to not work 4097 1.1 jruoho properly. ACPICA BZ 765. 4098 1.1 jruoho 4099 1.1 jruoho iASL: Implemented the -@ option to specify a Windows-style response file 4100 1.1 jruoho containing additional command line options. ACPICA BZ 801. 4101 1.1 jruoho 4102 1.1.1.3.2.1 yamt AcpiExec: Added support to load multiple AML files simultaneously (such 4103 1.1.1.3.2.1 yamt as 4104 1.1.1.3.2.1 yamt a 4105 1.1 jruoho DSDT and multiple SSDTs). Also added support for wildcards within the AML 4106 1.1 jruoho pathname. These features allow all machine tables to be easily loaded and 4107 1.1 jruoho debugged together. ACPICA BZ 804. 4108 1.1 jruoho 4109 1.1.1.3.2.1 yamt Disassembler: Added missing support for disassembly of HEST table Error 4110 1.1.1.3.2.1 yamt Bank 4111 1.1 jruoho subtables. 4112 1.1 jruoho 4113 1.1 jruoho ---------------------------------------- 4114 1.1 jruoho 30 July 2009. Summary of changes for version 20090730: 4115 1.1 jruoho 4116 1.1 jruoho The ACPI 4.0 implementation for ACPICA is complete with this release. 4117 1.1 jruoho 4118 1.1 jruoho 1) ACPI CA Core Subsystem: 4119 1.1 jruoho 4120 1.1 jruoho ACPI 4.0: Added header file support for all new and changed ACPI tables. 4121 1.1.1.3.2.1 yamt Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are 4122 1.1.1.3.2.1 yamt new 4123 1.1.1.3.2.1 yamt for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, 4124 1.1.1.3.2.1 yamt BERT, 4125 1.1.1.3.2.1 yamt EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. 4126 1.1.1.3.2.1 yamt There 4127 1.1 jruoho have been some ACPI 4.0 changes to other existing tables. Split the large 4128 1.1 jruoho actbl1.h header into the existing actbl2.h header. ACPICA BZ 774. 4129 1.1 jruoho 4130 1.1.1.3.2.1 yamt ACPI 4.0: Implemented predefined name validation for all new names. There 4131 1.1.1.3.2.1 yamt are 4132 1.1.1.3.2.1 yamt 31 new names in ACPI 4.0. The predefined validation module was split into 4133 1.1.1.3.2.1 yamt two 4134 1.1 jruoho files. The new file is namespace/nsrepair.c. ACPICA BZ 770. 4135 1.1 jruoho 4136 1.1 jruoho Implemented support for so-called "module-level executable code". This is 4137 1.1.1.3.2.1 yamt executable AML code that exists outside of any control method and is 4138 1.1.1.3.2.1 yamt intended 4139 1.1.1.3.2.1 yamt to be executed at table load time. Although illegal since ACPI 2.0, this 4140 1.1.1.3.2.1 yamt type 4141 1.1.1.3.2.1 yamt of code still exists and is apparently still being created. Blocks of 4142 1.1.1.3.2.1 yamt this 4143 1.1.1.3.2.1 yamt code are now detected and executed as intended. Currently, the code 4144 1.1.1.3.2.1 yamt blocks 4145 1.1 jruoho must exist under either an If, Else, or While construct; these are the 4146 1.1 jruoho typical cases seen in the field. ACPICA BZ 762. Lin Ming. 4147 1.1 jruoho 4148 1.1 jruoho Implemented an automatic dynamic repair for predefined names that return 4149 1.1.1.3.2.1 yamt nested Package objects. This applies to predefined names that are defined 4150 1.1.1.3.2.1 yamt to 4151 1.1 jruoho return a variable-length Package of sub-packages. If the number of sub- 4152 1.1.1.3.2.1 yamt packages is one, BIOS code is occasionally seen that creates a simple 4153 1.1.1.3.2.1 yamt single 4154 1.1 jruoho package with no sub-packages. This code attempts to fix the problem by 4155 1.1.1.3.2.1 yamt wrapping a new package object around the existing package. These methods 4156 1.1.1.3.2.1 yamt can 4157 1.1.1.3.2.1 yamt be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA 4158 1.1.1.3.2.1 yamt BZ 4159 1.1 jruoho 790. 4160 1.1 jruoho 4161 1.1.1.3.2.1 yamt Fixed a regression introduced in 20090625 for the AcpiGetDevices 4162 1.1.1.3.2.1 yamt interface. 4163 1.1.1.3.2.1 yamt The _HID/_CID matching was broken and no longer matched IDs correctly. 4164 1.1.1.3.2.1 yamt ACPICA 4165 1.1 jruoho BZ 793. 4166 1.1 jruoho 4167 1.1 jruoho Fixed a problem with AcpiReset where the reset would silently fail if the 4168 1.1.1.3.2.1 yamt register was one of the protected I/O ports. AcpiReset now bypasses the 4169 1.1.1.3.2.1 yamt port 4170 1.1.1.3.2.1 yamt validation mechanism. This may eventually be driven into the 4171 1.1.1.3.2.1 yamt AcpiRead/Write 4172 1.1 jruoho interfaces. 4173 1.1 jruoho 4174 1.1 jruoho Fixed a regression related to the recent update of the AcpiRead/Write 4175 1.1.1.3.2.1 yamt interfaces. A sleep/suspend could fail if the optional PM2 Control 4176 1.1.1.3.2.1 yamt register 4177 1.1 jruoho does not exist during an attempt to write the Bus Master Arbitration bit. 4178 1.1.1.3.2.1 yamt (However, some hosts already delete the code that writes this bit, and 4179 1.1.1.3.2.1 yamt the 4180 1.1 jruoho code may in fact be obsolete at this date.) ACPICA BZ 799. 4181 1.1 jruoho 4182 1.1.1.3.2.1 yamt Fixed a problem where AcpiTerminate could fault if inadvertently called 4183 1.1.1.3.2.1 yamt twice 4184 1.1 jruoho in succession. ACPICA BZ 795. 4185 1.1 jruoho 4186 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4187 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4188 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4189 1.1.1.3.2.1 yamt has a 4190 1.1 jruoho much larger code and data size. 4191 1.1 jruoho 4192 1.1 jruoho Previous Release: 4193 1.1 jruoho Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total 4194 1.1 jruoho Debug Version: 160.5K Code, 50.6K Data, 211.1K Total 4195 1.1 jruoho Current Release: 4196 1.1 jruoho Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total 4197 1.1 jruoho Debug Version: 161.6K Code, 50.9K Data, 212.5K Total 4198 1.1 jruoho 4199 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4200 1.1 jruoho 4201 1.1 jruoho ACPI 4.0: Implemented disassembler support for all new ACPI tables and 4202 1.1 jruoho changes to existing tables. ACPICA BZ 775. 4203 1.1 jruoho 4204 1.1 jruoho ---------------------------------------- 4205 1.1 jruoho 25 June 2009. Summary of changes for version 20090625: 4206 1.1 jruoho 4207 1.1 jruoho The ACPI 4.0 Specification was released on June 16 and is available at 4208 1.1 jruoho www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will 4209 1.1 jruoho continue for the next few releases. 4210 1.1 jruoho 4211 1.1 jruoho 1) ACPI CA Core Subsystem: 4212 1.1 jruoho 4213 1.1 jruoho ACPI 4.0: Implemented interpreter support for the IPMI operation region 4214 1.1.1.3.2.1 yamt address space. Includes support for bi-directional data buffers and an 4215 1.1.1.3.2.1 yamt IPMI 4216 1.1.1.3.2.1 yamt address space handler (to be installed by an IPMI device driver.) ACPICA 4217 1.1.1.3.2.1 yamt BZ 4218 1.1 jruoho 773. Lin Ming. 4219 1.1 jruoho 4220 1.1.1.3.2.1 yamt ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. 4221 1.1.1.3.2.1 yamt Includes 4222 1.1 jruoho support in both the header files and the disassembler. 4223 1.1 jruoho 4224 1.1 jruoho Completed a major update for the AcpiGetObjectInfo external interface. 4225 1.1 jruoho Changes include: 4226 1.1 jruoho - Support for variable, unlimited length HID, UID, and CID strings. 4227 1.1.1.3.2.1 yamt - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, 4228 1.1.1.3.2.1 yamt etc.) 4229 1.1 jruoho - Call the _SxW power methods on behalf of a device object. 4230 1.1 jruoho - Determine if a device is a PCI root bridge. 4231 1.1 jruoho - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. 4232 1.1.1.3.2.1 yamt These changes will require an update to all callers of this interface. 4233 1.1.1.3.2.1 yamt See 4234 1.1.1.3.2.1 yamt the updated ACPICA Programmer Reference for details. One new source file 4235 1.1.1.3.2.1 yamt has 4236 1.1 jruoho been added - utilities/utids.c. ACPICA BZ 368, 780. 4237 1.1 jruoho 4238 1.1 jruoho Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit 4239 1.1.1.3.2.1 yamt transfers. The Value parameter has been extended from 32 bits to 64 bits 4240 1.1.1.3.2.1 yamt in 4241 1.1.1.3.2.1 yamt order to support new ACPI 4.0 tables. These changes will require an 4242 1.1.1.3.2.1 yamt update 4243 1.1.1.3.2.1 yamt to 4244 1.1 jruoho all callers of these interfaces. See the ACPICA Programmer Reference for 4245 1.1 jruoho details. ACPICA BZ 768. 4246 1.1 jruoho 4247 1.1.1.3.2.1 yamt Fixed several problems with AcpiAttachData. The handler was not invoked 4248 1.1.1.3.2.1 yamt when 4249 1.1.1.3.2.1 yamt the host node was deleted. The data sub-object was not automatically 4250 1.1.1.3.2.1 yamt deleted 4251 1.1.1.3.2.1 yamt when the host node was deleted. The interface to the handler had an 4252 1.1.1.3.2.1 yamt unused 4253 1.1 jruoho parameter, this was removed. ACPICA BZ 778. 4254 1.1 jruoho 4255 1.1 jruoho Enhanced the function that dumps ACPI table headers. All non-printable 4256 1.1.1.3.2.1 yamt characters in the string fields are now replaced with '?' (Signature, 4257 1.1.1.3.2.1 yamt OemId, 4258 1.1 jruoho OemTableId, and CompilerId.) ACPI tables with non-printable characters in 4259 1.1 jruoho these fields are occasionally seen in the field. ACPICA BZ 788. 4260 1.1 jruoho 4261 1.1 jruoho Fixed a problem with predefined method repair code where the code that 4262 1.1.1.3.2.1 yamt attempts to repair/convert an object of incorrect type is only executed 4263 1.1.1.3.2.1 yamt on 4264 1.1.1.3.2.1 yamt the first time the predefined method is called. The mechanism that 4265 1.1.1.3.2.1 yamt disables 4266 1.1 jruoho warnings on subsequent calls was interfering with the repair mechanism. 4267 1.1 jruoho ACPICA BZ 781. 4268 1.1 jruoho 4269 1.1.1.3.2.1 yamt Fixed a possible memory leak in the predefined validation/repair code 4270 1.1.1.3.2.1 yamt when 4271 1.1.1.3.2.1 yamt a 4272 1.1 jruoho buffer is automatically converted to an expected string object. 4273 1.1 jruoho 4274 1.1.1.3.2.1 yamt Removed obsolete 16-bit files from the distribution and from the current 4275 1.1.1.3.2.1 yamt git 4276 1.1 jruoho tree head.

The 4280 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4281 1.1.1.3.2.1 yamt has a 4282 1.1 jruoho much larger code and data size. 4283 1.1 jruoho 4284 1.1 jruoho Previous Release: 4285 1.1 jruoho Non-Debug Version: 83.4K Code, 17.5K Data, 100.9K Total 4286 1.1 jruoho Debug Version: 158.9K Code, 50.0K Data, 208.9K Total 4287 1.1 jruoho Current Release: 4288 1.1 jruoho Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total 4289 1.1 jruoho Debug Version: 160.5K Code, 50.6K Data, 211.1K Total 4290 1.1 jruoho 4291 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4292 1.1 jruoho 4293 1.1 jruoho ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI 4294 1.1 jruoho operation region keyword. ACPICA BZ 771, 772. Lin Ming. 4295 1.1 jruoho 4296 1.1 jruoho ACPI 4.0: iASL - implemented compile-time validation support for all new 4297 1.1 jruoho predefined names and control methods (31 total). ACPICA BZ 769. 4298 1.1 jruoho 4299 1.1 jruoho ---------------------------------------- 4300 1.1 jruoho 21 May 2009. Summary of changes for version 20090521: 4301 1.1 jruoho 4302 1.1 jruoho 1) ACPI CA Core Subsystem: 4303 1.1 jruoho 4304 1.1.1.3.2.1 yamt Disabled the preservation of the SCI enable bit in the PM1 control 4305 1.1.1.3.2.1 yamt register. 4306 1.1.1.3.2.1 yamt The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification 4307 1.1.1.3.2.1 yamt to 4308 1.1.1.3.2.1 yamt be 4309 1.1 jruoho a "preserved" bit - "OSPM always preserves this bit position", section 4310 1.1 jruoho 4.7.3.2.1. However, some machines fail if this bit is in fact preserved 4311 1.1 jruoho because the bit needs to be explicitly set by the OS as a workaround. No 4312 1.1 jruoho machines fail if the bit is not preserved. Therefore, ACPICA no longer 4313 1.1 jruoho attempts to preserve this bit. 4314 1.1 jruoho 4315 1.1 jruoho Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or 4316 1.1 jruoho incorrectly formed _PRT package could cause a fault. Added validation to 4317 1.1 jruoho ensure that each package element is actually a sub-package. 4318 1.1 jruoho 4319 1.1.1.3.2.1 yamt Implemented a new interface to install or override a single control 4320 1.1.1.3.2.1 yamt method, 4321 1.1.1.3.2.1 yamt AcpiInstallMethod. This interface is useful when debugging in order to 4322 1.1.1.3.2.1 yamt repair 4323 1.1.1.3.2.1 yamt an existing method or to install a missing method without having to 4324 1.1.1.3.2.1 yamt override 4325 1.1 jruoho the entire ACPI table. See the ACPICA Programmer Reference for use and 4326 1.1 jruoho examples. Lin Ming, Bob Moore. 4327 1.1 jruoho 4328 1.1 jruoho Fixed several reference count issues with the DdbHandle object that is 4329 1.1.1.3.2.1 yamt created from a Load or LoadTable operator. Prevent premature deletion of 4330 1.1.1.3.2.1 yamt the 4331 1.1.1.3.2.1 yamt object. Also, mark the object as invalid once the table has been 4332 1.1.1.3.2.1 yamt unloaded. 4333 1.1.1.3.2.1 yamt This is needed because the handle itself may not be deleted after the 4334 1.1.1.3.2.1 yamt table 4335 1.1 jruoho unload, depending on whether it has been stored in a named object by the 4336 1.1 jruoho caller. Lin Ming. 4337 1.1 jruoho 4338 1.1 jruoho Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple 4339 1.1.1.3.2.1 yamt mutexes of the same sync level are acquired but then not released in 4340 1.1.1.3.2.1 yamt strict 4341 1.1.1.3.2.1 yamt opposite order, the internally maintained Current Sync Level becomes 4342 1.1.1.3.2.1 yamt confused 4343 1.1 jruoho and can cause subsequent execution errors. ACPICA BZ 471. 4344 1.1 jruoho 4345 1.1 jruoho Changed the allowable release order for ASL mutex objects. The ACPI 4.0 4346 1.1.1.3.2.1 yamt specification has been changed to make the SyncLevel for mutex objects 4347 1.1.1.3.2.1 yamt more 4348 1.1.1.3.2.1 yamt useful. When releasing a mutex, the SyncLevel of the mutex must now be 4349 1.1.1.3.2.1 yamt the 4350 1.1.1.3.2.1 yamt same as the current sync level. This makes more sense than the previous 4351 1.1.1.3.2.1 yamt rule 4352 1.1 jruoho (SyncLevel less than or equal). This change updates the code to match the 4353 1.1 jruoho specification. 4354 1.1 jruoho 4355 1.1.1.3.2.1 yamt Fixed a problem with the local version of the AcpiOsPurgeCache function. 4356 1.1.1.3.2.1 yamt The 4357 1.1 jruoho (local) cache must be locked during all cache object deletions. Andrew 4358 1.1 jruoho Baumann. 4359 1.1 jruoho 4360 1.1.1.3.2.1 yamt Updated the Load operator to use operation region interfaces. This 4361 1.1.1.3.2.1 yamt replaces 4362 1.1.1.3.2.1 yamt direct memory mapping with region access calls. Now, all region accesses 4363 1.1.1.3.2.1 yamt go 4364 1.1 jruoho through the installed region handler as they should. 4365 1.1 jruoho 4366 1.1.1.3.2.1 yamt Simplified and optimized the NsGetNextNode function. Reduced parameter 4367 1.1.1.3.2.1 yamt count 4368 1.1 jruoho and reduced code for this frequently used function. 4369 1.1 jruoho 4370 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4371 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4372 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4373 1.1.1.3.2.1 yamt has a 4374 1.1 jruoho much larger code and data size. 4375 1.1 jruoho 4376 1.1 jruoho Previous Release: 4377 1.1 jruoho Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 4378 1.1 jruoho Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 4379 1.1 jruoho Current Release: 4380 1.1 jruoho Non-Debug Version: 83.4K Code, 17.5K Data, 100.9K Total 4381 1.1 jruoho Debug Version: 158.9K Code, 50.0K Data, 208.9K Total 4382 1.1 jruoho 4383 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4384 1.1 jruoho 4385 1.1.1.3.2.1 yamt Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some 4386 1.1.1.3.2.1 yamt problems 4387 1.1.1.3.2.1 yamt with sub-table disassembly and handling invalid sub-tables. Attempt 4388 1.1.1.3.2.1 yamt recovery 4389 1.1 jruoho after an invalid sub-table ID. 4390 1.1 jruoho 4391 1.1 jruoho ---------------------------------------- 4392 1.1 jruoho 22 April 2009. Summary of changes for version 20090422: 4393 1.1 jruoho 4394 1.1 jruoho 1) ACPI CA Core Subsystem: 4395 1.1 jruoho 4396 1.1.1.3.2.1 yamt Fixed a compatibility issue with the recently released I/O port 4397 1.1.1.3.2.1 yamt protection 4398 1.1 jruoho mechanism. For windows compatibility, 1) On a port protection violation, 4399 1.1.1.3.2.1 yamt simply ignore the request and do not return an exception (allow the 4400 1.1.1.3.2.1 yamt control 4401 1.1 jruoho method to continue execution.) 2) If only part of the request overlaps a 4402 1.1.1.3.2.1 yamt protected port, read/write the individual ports that are not protected. 4403 1.1.1.3.2.1 yamt Linux 4404 1.1 jruoho BZ 13036. Lin Ming 4405 1.1 jruoho 4406 1.1.1.3.2.1 yamt Enhanced the execution of the ASL/AML BreakPoint operator so that it 4407 1.1.1.3.2.1 yamt actually 4408 1.1 jruoho breaks into the AML debugger if the debugger is present. This matches the 4409 1.1 jruoho ACPI-defined behavior. 4410 1.1 jruoho 4411 1.1 jruoho Fixed several possible warnings related to the use of the configurable 4412 1.1 jruoho ACPI_THREAD_ID. This type can now be configured as either an integer or a 4413 1.1 jruoho pointer with no warnings. Also fixes several warnings in printf-like 4414 1.1 jruoho statements for the 64-bit build when the type is configured as a pointer. 4415 1.1 jruoho ACPICA BZ 766, 767. 4416 1.1 jruoho 4417 1.1.1.3.2.1 yamt Fixed a number of possible warnings when compiling with gcc 4+ (depending 4418 1.1.1.3.2.1 yamt on 4419 1.1.1.3.2.1 yamt warning options.) Examples include printf formats, aliasing, unused 4420 1.1.1.3.2.1 yamt globals, 4421 1.1 jruoho missing prototypes, missing switch default statements, use of non-ANSI 4422 1.1.1.3.2.1 yamt library functions, use of non-ANSI constructs. See generate/unix/Makefile 4423 1.1.1.3.2.1 yamt for 4424 1.1 jruoho a list of warning options used with gcc 3 and 4. ACPICA BZ 735. 4425 1.1 jruoho 4426 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4427 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4428 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4429 1.1.1.3.2.1 yamt has a 4430 1.1 jruoho much larger code and data size. 4431 1.1 jruoho 4432 1.1 jruoho Previous Release: 4433 1.1 jruoho Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 4434 1.1 jruoho Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 4435 1.1 jruoho Current Release: 4436 1.1 jruoho Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 4437 1.1 jruoho Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 4438 1.1 jruoho 4439 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4440 1.1 jruoho 4441 1.1.1.3.2.1 yamt iASL: Fixed a generation warning from Bison 2.3 and fixed several 4442 1.1.1.3.2.1 yamt warnings 4443 1.1.1.3.2.1 yamt on 4444 1.1 jruoho the 64-bit build. 4445 1.1 jruoho 4446 1.1.1.3.2.1 yamt iASL: Fixed a problem where the Unix/Linux versions of the compiler could 4447 1.1.1.3.2.1 yamt not 4448 1.1 jruoho correctly digest Windows/DOS formatted files (with CR/LF). 4449 1.1 jruoho 4450 1.1 jruoho iASL: Added a new option for "quiet mode" (-va) that produces only the 4451 1.1 jruoho compilation summary, not individual errors and warnings. Useful for large 4452 1.1 jruoho batch compilations. 4453 1.1 jruoho 4454 1.1.1.3.2.1 yamt AcpiExec: Implemented a new option (-z) to enable a forced 4455 1.1.1.3.2.1 yamt semaphore/mutex 4456 1.1.1.3.2.1 yamt timeout that can be used to detect hang conditions during execution of 4457 1.1.1.3.2.1 yamt AML 4458 1.1.1.3.2.1 yamt code (includes both internal semaphores and AML-defined mutexes and 4459 1.1.1.3.2.1 yamt events.) 4460 1.1 jruoho 4461 1.1 jruoho Added new makefiles for the generation of acpica in a generic unix-like 4462 1.1.1.3.2.1 yamt environment. These makefiles are intended to generate the acpica tools 4463 1.1.1.3.2.1 yamt and 4464 1.1 jruoho utilities from the original acpica git source tree structure. 4465 1.1 jruoho 4466 1.1 jruoho Test Suites: Updated and cleaned up the documentation files. Updated the 4467 1.1.1.3.2.1 yamt copyrights to 2009, affecting all source files. Use the new version of 4468 1.1.1.3.2.1 yamt iASL 4469 1.1.1.3.2.1 yamt with quiet mode. Increased the number of available semaphores in the 4470 1.1.1.3.2.1 yamt Windows 4471 1.1.1.3.2.1 yamt OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, 4472 1.1.1.3.2.1 yamt added 4473 1.1 jruoho an alternate implementation of the semaphore timeout to allow aslts to 4474 1.1 jruoho execute fully on Cygwin. 4475 1.1 jruoho 4476 1.1 jruoho ---------------------------------------- 4477 1.1 jruoho 20 March 2009. Summary of changes for version 20090320: 4478 1.1 jruoho 4479 1.1 jruoho 1) ACPI CA Core Subsystem: 4480 1.1 jruoho 4481 1.1.1.3.2.1 yamt Fixed a possible race condition between AcpiWalkNamespace and dynamic 4482 1.1.1.3.2.1 yamt table 4483 1.1.1.3.2.1 yamt unloads. Added a reader/writer locking mechanism to allow multiple 4484 1.1.1.3.2.1 yamt concurrent 4485 1.1.1.3.2.1 yamt namespace walks (readers), but block a dynamic table unload until it can 4486 1.1.1.3.2.1 yamt gain 4487 1.1.1.3.2.1 yamt exclusive write access to the namespace. This fixes a problem where a 4488 1.1.1.3.2.1 yamt table 4489 1.1.1.3.2.1 yamt unload could (possibly catastrophically) delete the portion of the 4490 1.1.1.3.2.1 yamt namespace 4491 1.1.1.3.2.1 yamt that is currently being examined by a walk. Adds a new file, utlock.c, 4492 1.1.1.3.2.1 yamt that 4493 1.1 jruoho implements the reader/writer lock mechanism. ACPICA BZ 749. 4494 1.1 jruoho 4495 1.1.1.3.2.1 yamt Fixed a regression introduced in version 20090220 where a change to the 4496 1.1.1.3.2.1 yamt FADT 4497 1.1.1.3.2.1 yamt handling could cause the ACPICA subsystem to access non-existent I/O 4498 1.1.1.3.2.1 yamt ports. 4499 1.1 jruoho 4500 1.1.1.3.2.1 yamt Modified the handling of FADT register and table (FACS/DSDT) addresses. 4501 1.1.1.3.2.1 yamt The 4502 1.1 jruoho FADT can contain both 32-bit and 64-bit versions of these addresses. 4503 1.1.1.3.2.1 yamt Previously, the 64-bit versions were favored, meaning that if both 32 and 4504 1.1.1.3.2.1 yamt 64 4505 1.1 jruoho versions were valid, but not equal, the 64-bit version was used. This was 4506 1.1.1.3.2.1 yamt found to cause some machines to fail. Now, in this case, the 32-bit 4507 1.1.1.3.2.1 yamt version 4508 1.1 jruoho is used instead. This now matches the Windows behavior. 4509 1.1 jruoho 4510 1.1.1.3.2.1 yamt Implemented a new mechanism to protect certain I/O ports. Provides 4511 1.1.1.3.2.1 yamt Microsoft 4512 1.1 jruoho compatibility and protects the standard PC I/O ports from access via AML 4513 1.1 jruoho code. Adds a new file, hwvalid.c 4514 1.1 jruoho 4515 1.1 jruoho Fixed a possible extraneous warning message from the FADT support. The 4516 1.1 jruoho message warns of a 32/64 length mismatch between the legacy and GAS 4517 1.1 jruoho definitions for a register. 4518 1.1 jruoho 4519 1.1.1.3.2.1 yamt Removed the obsolete AcpiOsValidateAddress OSL interface. This interface 4520 1.1.1.3.2.1 yamt is 4521 1.1.1.3.2.1 yamt made obsolete by the port protection mechanism above. It was previously 4522 1.1.1.3.2.1 yamt used 4523 1.1.1.3.2.1 yamt to validate the entire address range of an operation region, which could 4524 1.1.1.3.2.1 yamt be 4525 1.1 jruoho incorrect if the range included illegal ports, but fields within the 4526 1.1 jruoho operation region did not actually access those ports. Validation is now 4527 1.1 jruoho performed on a per-field basis instead of the entire region. 4528 1.1 jruoho 4529 1.1 jruoho Modified the handling of the PM1 Status Register ignored bit (bit 11.) 4530 1.1.1.3.2.1 yamt Ignored bits must be "preserved" according to the ACPI spec. Usually, 4531 1.1.1.3.2.1 yamt this 4532 1.1.1.3.2.1 yamt means a read/modify/write when writing to the register. However, for 4533 1.1.1.3.2.1 yamt status 4534 1.1.1.3.2.1 yamt registers, writing a one means clear the event. Writing a zero means 4535 1.1.1.3.2.1 yamt preserve 4536 1.1.1.3.2.1 yamt the event (do not clear.) This behavior is clarified in the ACPI 4.0 4537 1.1.1.3.2.1 yamt spec, 4538 1.1 jruoho and the ACPICA code now simply always writes a zero to the ignored bit. 4539 1.1 jruoho 4540 1.1.1.3.2.1 yamt Modified the handling of ignored bits for the PM1 A/B Control Registers. 4541 1.1.1.3.2.1 yamt As 4542 1.1 jruoho per the ACPI specification, for the control registers, preserve 4543 1.1.1.3.2.1 yamt (read/modify/write) all bits that are defined as either reserved or 4544 1.1.1.3.2.1 yamt ignored. 4545 1.1 jruoho 4546 1.1 jruoho Updated the handling of write-only bits in the PM1 A/B Control Registers. 4547 1.1 jruoho When reading the register, zero the write-only bits as per the ACPI spec. 4548 1.1 jruoho ACPICA BZ 443. Lin Ming. 4549 1.1 jruoho 4550 1.1 jruoho Removed "Linux" from the list of supported _OSI strings. Linux no longer 4551 1.1.1.3.2.1 yamt wants to reply true to this request. The Windows strings are the only 4552 1.1.1.3.2.1 yamt paths 4553 1.1 jruoho through the AML that are tested and known to work properly. 4554 1.1 jruoho 4555 1.1 jruoho Previous Release: 4556 1.1 jruoho Non-Debug Version: 82.0K Code, 17.5K Data, 99.5K Total 4557 1.1 jruoho Debug Version: 156.9K Code, 49.8K Data, 206.7K Total 4558 1.1 jruoho Current Release: 4559 1.1 jruoho Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 4560 1.1 jruoho Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 4561 1.1 jruoho 4562 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4563 1.1 jruoho 4564 1.1.1.3.2.1 yamt Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c 4565 1.1.1.3.2.1 yamt and 4566 1.1 jruoho aetables.c 4567 1.1 jruoho 4568 1.1 jruoho ---------------------------------------- 4569 1.1 jruoho 20 February 2009. Summary of changes for version 20090220: 4570 1.1 jruoho 4571 1.1 jruoho 1) ACPI CA Core Subsystem: 4572 1.1 jruoho 4573 1.1.1.3.2.1 yamt Optimized the ACPI register locking. Removed locking for reads from the 4574 1.1.1.3.2.1 yamt ACPI 4575 1.1.1.3.2.1 yamt bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock 4576 1.1.1.3.2.1 yamt is 4577 1.1 jruoho not required when reading the single-bit registers. The 4578 1.1.1.3.2.1 yamt AcpiGetRegisterUnlocked function is no longer needed and has been 4579 1.1.1.3.2.1 yamt removed. 4580 1.1.1.3.2.1 yamt This will improve performance for reads on these registers. ACPICA BZ 4581 1.1.1.3.2.1 yamt 760. 4582 1.1 jruoho 4583 1.1 jruoho Fixed the parameter validation for AcpiRead/Write. Now return 4584 1.1.1.3.2.1 yamt AE_BAD_PARAMETER if the input register pointer is null, and 4585 1.1.1.3.2.1 yamt AE_BAD_ADDRESS 4586 1.1.1.3.2.1 yamt if 4587 1.1.1.3.2.1 yamt the register has an address of zero. Previously, these cases simply 4588 1.1.1.3.2.1 yamt returned 4589 1.1.1.3.2.1 yamt AE_OK. For optional registers such as PM1B status/enable/control, the 4590 1.1.1.3.2.1 yamt caller 4591 1.1 jruoho should check for a valid register address before calling. ACPICA BZ 748. 4592 1.1 jruoho 4593 1.1 jruoho Renamed the external ACPI bit register access functions. Renamed 4594 1.1 jruoho AcpiGetRegister and AcpiSetRegister to clarify the purpose of these 4595 1.1.1.3.2.1 yamt functions. The new names are AcpiReadBitRegister and 4596 1.1.1.3.2.1 yamt AcpiWriteBitRegister. 4597 1.1.1.3.2.1 yamt Also, restructured the code for these functions by simplifying the code 4598 1.1.1.3.2.1 yamt path 4599 1.1 jruoho and condensing duplicate code to reduce code size. 4600 1.1 jruoho 4601 1.1 jruoho Added new functions to transparently handle the possibly split PM1 A/B 4602 1.1.1.3.2.1 yamt registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two 4603 1.1.1.3.2.1 yamt functions 4604 1.1.1.3.2.1 yamt now handle the split registers for PM1 Status, Enable, and Control. 4605 1.1.1.3.2.1 yamt ACPICA 4606 1.1.1.3.2.1 yamt BZ 4607 1.1 jruoho 746. 4608 1.1 jruoho 4609 1.1.1.3.2.1 yamt Added a function to handle the PM1 control registers, 4610 1.1.1.3.2.1 yamt AcpiHwWritePm1Control. 4611 1.1.1.3.2.1 yamt This function writes both of the PM1 control registers (A/B). These 4612 1.1.1.3.2.1 yamt registers 4613 1.1.1.3.2.1 yamt are different than the PM1 A/B status and enable registers in that 4614 1.1.1.3.2.1 yamt different 4615 1.1.1.3.2.1 yamt values can be written to the A/B registers. Most notably, the SLP_TYP 4616 1.1.1.3.2.1 yamt bits 4617 1.1.1.3.2.1 yamt can be different, as per the values returned from the _Sx predefined 4618 1.1.1.3.2.1 yamt methods. 4619 1.1.1.3.2.1 yamt 4620 1.1.1.3.2.1 yamt Removed an extra register write within AcpiHwClearAcpiStatus. This 4621 1.1.1.3.2.1 yamt function 4622 1.1.1.3.2.1 yamt was writing an optional PM1B status register twice. The existing call to 4623 1.1.1.3.2.1 yamt the 4624 1.1.1.3.2.1 yamt low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 4625 1.1.1.3.2.1 yamt A/B 4626 1.1 jruoho register. ACPICA BZ 751. 4627 1.1 jruoho 4628 1.1.1.3.2.1 yamt Split out the PM1 Status registers from the FADT. Added new globals for 4629 1.1.1.3.2.1 yamt these 4630 1.1 jruoho registers (A/B), similar to the way the PM1 Enable registers are handled. 4631 1.1.1.3.2.1 yamt Instead of overloading the FADT Event Register blocks. This makes the 4632 1.1.1.3.2.1 yamt code 4633 1.1 jruoho clearer and less prone to error. 4634 1.1 jruoho 4635 1.1.1.3.2.1 yamt Fixed the warning message for when the platform contains too many ACPI 4636 1.1.1.3.2.1 yamt tables 4637 1.1.1.3.2.1 yamt for the default size of the global root table data structure. The 4638 1.1.1.3.2.1 yamt calculation 4639 1.1 jruoho for the truncation value was incorrect. 4640 1.1 jruoho 4641 1.1 jruoho Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this 4642 1.1.1.3.2.1 yamt obsolete macro, since it is now a simple reference to ->common.type. 4643 1.1.1.3.2.1 yamt There 4644 1.1 jruoho were about 150 invocations of the macro across 41 files. ACPICA BZ 755. 4645 1.1 jruoho 4646 1.1 jruoho Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as 4647 1.1 jruoho TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to 4648 1.1 jruoho simply SLEEP_TYPE. ACPICA BZ 754. 4649 1.1 jruoho 4650 1.1 jruoho Conditionally compile the AcpiSetFirmwareWakingVector64 function. This 4651 1.1 jruoho function is only needed on 64-bit host operating systems and is thus not 4652 1.1 jruoho included for 32-bit hosts. 4653 1.1 jruoho 4654 1.1.1.3.2.1 yamt Debug output: print the input and result for invocations of the _OSI 4655 1.1.1.3.2.1 yamt reserved 4656 1.1.1.3.2.1 yamt control method via the ACPI_LV_INFO debug level. Also, reduced some of 4657 1.1.1.3.2.1 yamt the 4658 1.1 jruoho verbosity of this debug level. Len Brown. 4659 1.1 jruoho 4660 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4661 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4662 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4663 1.1.1.3.2.1 yamt has a 4664 1.1 jruoho much larger code and data size. 4665 1.1 jruoho 4666 1.1 jruoho Previous Release: 4667 1.1 jruoho Non-Debug Version: 82.3K Code, 17.5K Data, 99.8K Total 4668 1.1 jruoho Debug Version: 157.3K Code, 49.8K Data, 207.1K Total 4669 1.1 jruoho Current Release: 4670 1.1 jruoho Non-Debug Version: 82.0K Code, 17.5K Data, 99.5K Total 4671 1.1 jruoho Debug Version: 156.9K Code, 49.8K Data, 206.7K Total 4672 1.1 jruoho 4673 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4674 1.1 jruoho 4675 1.1 jruoho Disassembler: Decode the FADT PM_Profile field.

Summary of changes for version 20090123: 4680 1.1 jruoho 4681 1.1 jruoho 1) ACPI CA Core Subsystem: 4682 1.1 jruoho 4683 1.1 jruoho Added the 2009 copyright to all module headers and signons. This affects 4684 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, and 4685 1.1 jruoho the tools/utilities. 4686 1.1 jruoho 4687 1.1.1.3.2.1 yamt Implemented a change to allow the host to override any ACPI table, 4688 1.1.1.3.2.1 yamt including 4689 1.1.1.3.2.1 yamt dynamically loaded tables. Previously, only the DSDT could be replaced by 4690 1.1.1.3.2.1 yamt the 4691 1.1.1.3.2.1 yamt host. With this change, the AcpiOsTableOverride interface is called for 4692 1.1.1.3.2.1 yamt each 4693 1.1.1.3.2.1 yamt table found in the RSDT/XSDT during ACPICA initialization, and also 4694 1.1.1.3.2.1 yamt whenever 4695 1.1 jruoho a table is dynamically loaded via the AML Load operator. 4696 1.1 jruoho 4697 1.1 jruoho Updated FADT flag definitions, especially the Boot Architecture flags. 4698 1.1 jruoho 4699 1.1.1.3.2.1 yamt Debugger: For the Find command, automatically pad the input ACPI name 4700 1.1.1.3.2.1 yamt with 4701 1.1.1.3.2.1 yamt underscores if the name is shorter than 4 characters. This enables a 4702 1.1.1.3.2.1 yamt match 4703 1.1 jruoho with the actual namespace entry which is itself padded with underscores. 4704 1.1 jruoho 4705 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4706 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4707 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4708 1.1.1.3.2.1 yamt has a 4709 1.1 jruoho much larger code and data size. 4710 1.1 jruoho 4711 1.1 jruoho Previous Release: 4712 1.1 jruoho Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total 4713 1.1 jruoho Debug Version: 157.1K Code, 49.7K Data, 206.8K Total 4714 1.1 jruoho Current Release: 4715 1.1 jruoho Non-Debug Version: 82.3K Code, 17.5K Data, 99.8K Total 4716 1.1 jruoho Debug Version: 157.3K Code, 49.8K Data, 207.1K Total 4717 1.1 jruoho 4718 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4719 1.1 jruoho 4720 1.1 jruoho Fix build error under Bison-2.4. 4721 1.1 jruoho 4722 1.1.1.3.2.1 yamt Dissasembler: Enhanced FADT support. Added decoding of the Boot 4723 1.1.1.3.2.1 yamt Architecture 4724 1.1 jruoho flags. Now decode all flags, regardless of the FADT version. Flag output 4725 1.1 jruoho includes the FADT version which first defined each flag. 4726 1.1 jruoho 4727 1.1.1.3.2.1 yamt The iASL -g option now dumps the RSDT to a file (in addition to the FADT 4728 1.1.1.3.2.1 yamt and 4729 1.1 jruoho DSDT). Windows only. 4730 1.1 jruoho 4731 1.1 jruoho ---------------------------------------- 4732 1.1 jruoho 04 December 2008. Summary of changes for version 20081204: 4733 1.1 jruoho 4734 1.1 jruoho 1) ACPI CA Core Subsystem: 4735 1.1 jruoho 4736 1.1.1.3.2.1 yamt The ACPICA Programmer Reference has been completely updated and revamped 4737 1.1.1.3.2.1 yamt for 4738 1.1 jruoho this release. This includes updates to the external interfaces, OSL 4739 1.1 jruoho interfaces, the overview sections, and the debugger reference. 4740 1.1 jruoho 4741 1.1 jruoho Several new ACPICA interfaces have been implemented and documented in the 4742 1.1 jruoho programmer reference: 4743 1.1 jruoho AcpiReset - Writes the reset value to the FADT-defined reset register. 4744 1.1 jruoho AcpiDisableAllGpes - Disable all available GPEs. 4745 1.1 jruoho AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs. 4746 1.1 jruoho AcpiGetGpeDevice - Get the GPE block device associated with a GPE. 4747 1.1 jruoho AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs. 4748 1.1 jruoho AcpiRead - Low-level read ACPI register (was HwLowLevelRead.) 4749 1.1 jruoho AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.) 4750 1.1 jruoho 4751 1.1.1.3.2.1 yamt Most of the public ACPI hardware-related interfaces have been moved to a 4752 1.1.1.3.2.1 yamt new 4753 1.1 jruoho file, components/hardware/hwxface.c 4754 1.1 jruoho 4755 1.1 jruoho Enhanced the FADT parsing and low-level ACPI register access: The ACPI 4756 1.1 jruoho register lengths within the FADT are now used, and the low level ACPI 4757 1.1 jruoho register access no longer hardcodes the ACPI register lengths. Given that 4758 1.1.1.3.2.1 yamt there may be some risk in actually trusting the FADT register lengths, a 4759 1.1.1.3.2.1 yamt run- 4760 1.1.1.3.2.1 yamt time option was added to fall back to the default hardcoded lengths if 4761 1.1.1.3.2.1 yamt the 4762 1.1 jruoho FADT proves to contain incorrect values - UseDefaultRegisterWidths. This 4763 1.1.1.3.2.1 yamt option is set to true for now, and a warning is issued if a suspicious 4764 1.1.1.3.2.1 yamt FADT 4765 1.1 jruoho register length is overridden with the default value. 4766 1.1 jruoho 4767 1.1.1.3.2.1 yamt Fixed a reference count issue in NsRepairObject. This problem was 4768 1.1.1.3.2.1 yamt introduced 4769 1.1 jruoho in version 20081031 as part of a fix to repair Buffer objects within 4770 1.1 jruoho Packages. Lin Ming. 4771 1.1 jruoho 4772 1.1 jruoho Added semaphore support to the Linux/Unix application OS-services layer 4773 1.1 jruoho (OSL). ACPICA BZ 448. Lin Ming. 4774 1.1 jruoho 4775 1.1.1.3.2.1 yamt Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes 4776 1.1.1.3.2.1 yamt will 4777 1.1 jruoho be implemented in the OSL, or will binary semaphores be used instead. 4778 1.1 jruoho 4779 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 4780 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 4781 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 4782 1.1.1.3.2.1 yamt has a 4783 1.1 jruoho much larger code and data size. 4784 1.1 jruoho 4785 1.1 jruoho Previous Release: 4786 1.1 jruoho Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total 4787 1.1 jruoho Debug Version: 156.4K Code, 49.4K Data, 205.8K Total 4788 1.1 jruoho Current Release: 4789 1.1 jruoho Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total 4790 1.1 jruoho Debug Version: 157.1K Code, 49.7K Data, 206.8K Total 4791 1.1 jruoho 4792 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 4793 1.1 jruoho 4794 1.1.1.3.2.1 yamt iASL: Completed the '-e' option to include additional ACPI tables in 4795 1.1.1.3.2.1 yamt order 4796 1.1.1.3.2.1 yamt to 4797 1.1.1.3.2.1 yamt aid with disassembly and External statement generation. ACPICA BZ 742. 4798 1.1.1.3.2.1 yamt Lin 4799 1.1 jruoho Ming. 4800 1.1 jruoho 4801 1.1 jruoho iASL: Removed the "named object in while loop" error. The compiler cannot 4802 1.1 jruoho determine how many times a loop will execute. ACPICA BZ 730. 4803 1.1 jruoho 4804 1.1.1.3.2.1 yamt Disassembler: Implemented support for FADT revision 2 (MS extension). 4805 1.1.1.3.2.1 yamt ACPICA 4806 1.1 jruoho BZ 743. 4807 1.1 jruoho 4808 1.1.1.3.2.1 yamt Disassembler: Updates for several ACPI data tables (HEST, EINJ, and 4809 1.1.1.3.2.1 yamt MCFG). 4810 1.1 jruoho 4811 1.1 jruoho ---------------------------------------- 4812 1.1 jruoho 31 October 2008. Summary of changes for version 20081031: 4813 1.1 jruoho 4814 1.1 jruoho 1) ACPI CA Core Subsystem: 4815 1.1 jruoho 4816 1.1.1.3.2.1 yamt Restructured the ACPICA header files into public/private. acpi.h now 4817 1.1.1.3.2.1 yamt includes 4818 1.1.1.3.2.1 yamt only the "public" acpica headers. All other acpica headers are "private" 4819 1.1.1.3.2.1 yamt and 4820 1.1.1.3.2.1 yamt should not be included by acpica users. One new file, accommon.h is used 4821 1.1.1.3.2.1 yamt to 4822 1.1.1.3.2.1 yamt include the commonly used private headers for acpica code generation. 4823 1.1.1.3.2.1 yamt Future 4824 1.1 jruoho plans include moving all private headers to a new subdirectory. 4825 1.1 jruoho 4826 1.1 jruoho Implemented an automatic Buffer->String return value conversion for 4827 1.1.1.3.2.1 yamt predefined ACPI methods. For these methods (such as _BIF), added 4828 1.1.1.3.2.1 yamt automatic 4829 1.1.1.3.2.1 yamt conversion for return objects that are required to be a String, but a 4830 1.1.1.3.2.1 yamt Buffer 4831 1.1.1.3.2.1 yamt was found instead. This can happen when reading string battery data from 4832 1.1.1.3.2.1 yamt an 4833 1.1.1.3.2.1 yamt operation region, because it used to be difficult to convert the data 4834 1.1.1.3.2.1 yamt from 4835 1.1.1.3.2.1 yamt buffer to string from within the ASL. Ensures that the host OS is 4836 1.1.1.3.2.1 yamt provided 4837 1.1 jruoho with a valid null-terminated string. Linux BZ 11822. 4838 1.1 jruoho 4839 1.1.1.3.2.1 yamt Updated the FACS waking vector interfaces. Split 4840 1.1.1.3.2.1 yamt AcpiSetFirmwareWakingVector 4841 1.1.1.3.2.1 yamt into two: one for the 32-bit vector, another for the 64-bit vector. This 4842 1.1.1.3.2.1 yamt is 4843 1.1.1.3.2.1 yamt required because the host OS must setup the wake much differently for 4844 1.1.1.3.2.1 yamt each 4845 1.1.1.3.2.1 yamt vector (real vs. protected mode, etc.) and the interface itself should 4846 1.1.1.3.2.1 yamt not 4847 1.1.1.3.2.1 yamt be 4848 1.1.1.3.2.1 yamt deciding which vector to use. Also, eliminated the 4849 1.1.1.3.2.1 yamt GetFirmwareWakingVector 4850 1.1.1.3.2.1 yamt interface, as it served no purpose (only the firmware reads the vector, 4851 1.1.1.3.2.1 yamt OS 4852 1.1 jruoho only writes the vector.) ACPICA BZ 731. 4853 1.1 jruoho 4854 1.1.1.3.2.1 yamt Implemented a mechanism to escape infinite AML While() loops. Added a 4855 1.1.1.3.2.1 yamt loop 4856 1.1.1.3.2.1 yamt counter to force exit from AML While loops if the count becomes too 4857 1.1.1.3.2.1 yamt large. 4858 1.1 jruoho This can occur in poorly written AML when the hardware does not respond 4859 1.1.1.3.2.1 yamt within a while loop and the loop does not implement a timeout. The 4860 1.1.1.3.2.1 yamt maximum 4861 1.1.1.3.2.1 yamt loop count is configurable. A new exception code is returned when a loop 4862 1.1.1.3.2.1 yamt is 4863 1.1 jruoho broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore. 4864 1.1 jruoho 4865 1.1 jruoho Optimized the execution of AML While loops. Previously, a control state 4866 1.1 jruoho object was allocated and freed for each execution of the loop. The 4867 1.1.1.3.2.1 yamt optimization is to simply reuse the control state for each iteration. 4868 1.1.1.3.2.1 yamt This 4869 1.1 jruoho speeds up the raw loop execution time by about 5%. 4870 1.1 jruoho 4871 1.1.1.3.2.1 yamt Enhanced the implicit return mechanism. For Windows compatibility, return 4872 1.1.1.3.2.1 yamt an 4873 1.1.1.3.2.1 yamt implicit integer of value zero for methods that contain no executable 4874 1.1.1.3.2.1 yamt code. 4875 1.1 jruoho Such methods are seen in the field as stubs (presumably), and can cause 4876 1.1 jruoho drivers to fail if they expect a return value. Lin Ming. 4877 1.1 jruoho 4878 1.1 jruoho Allow multiple backslashes as root prefixes in namepaths. In a fully 4879 1.1.1.3.2.1 yamt qualified namepath, allow multiple backslash prefixes. This can happen 4880 1.1.1.3.2.1 yamt (and 4881 1.1 jruoho is seen in the field) because of the use of a double-backslash in strings 4882 1.1.1.3.2.1 yamt (since backslash is the escape character) causing confusion. ACPICA BZ 4883 1.1.1.3.2.1 yamt 739 4884 1.1 jruoho Lin Ming. 4885 1.1 jruoho 4886 1.1 jruoho Emit a warning if two different FACS or DSDT tables are discovered in the 4887 1.1.1.3.2.1 yamt FADT. Checks if there are two valid but different addresses for the FACS 4888 1.1.1.3.2.1 yamt and 4889 1.1 jruoho DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.) 4890 1.1 jruoho 4891 1.1.1.3.2.1 yamt Consolidated the method argument count validation code. Merged the code 4892 1.1.1.3.2.1 yamt that 4893 1.1 jruoho validates control method argument counts into the predefined validation 4894 1.1.1.3.2.1 yamt module.

Summary of changes for version 20080926: 4946 1.1 jruoho 4947 1.1 jruoho 1) ACPI CA Core Subsystem: 4948 1.1 jruoho 4949 1.1.1.3.2.1 yamt Designed and implemented a mechanism to validate predefined ACPI methods 4950 1.1.1.3.2.1 yamt and 4951 1.1.1.3.2.1 yamt objects. This code validates the predefined ACPI objects (objects whose 4952 1.1.1.3.2.1 yamt names 4953 1.1 jruoho start with underscore) that appear in the namespace, at the time they are 4954 1.1 jruoho evaluated. The argument count and the type of the returned object are 4955 1.1.1.3.2.1 yamt validated against the ACPI specification. The purpose of this validation 4956 1.1.1.3.2.1 yamt is 4957 1.1.1.3.2.1 yamt to detect problems with the BIOS-implemented predefined ACPI objects 4958 1.1.1.3.2.1 yamt before 4959 1.1.1.3.2.1 yamt the results are returned to the ACPI-related drivers. Future enhancements 4960 1.1.1.3.2.1 yamt may 4961 1.1 jruoho include actual repair of incorrect return objects where possible. Two new 4962 1.1 jruoho files are nspredef.c and acpredef.h. 4963 1.1 jruoho 4964 1.1.1.3.2.1 yamt Fixed a fault in the AML parser if a memory allocation fails during the 4965 1.1.1.3.2.1 yamt Op 4966 1.1 jruoho completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492. 4967 1.1 jruoho 4968 1.1.1.3.2.1 yamt Fixed an issue with implicit return compatibility. This change improves 4969 1.1.1.3.2.1 yamt the 4970 1.1.1.3.2.1 yamt implicit return mechanism to be more compatible with the MS interpreter. 4971 1.1.1.3.2.1 yamt Lin 4972 1.1 jruoho Ming, ACPICA BZ 349. 4973 1.1 jruoho 4974 1.1.1.3.2.1 yamt Implemented support for zero-length buffer-to-string conversions. Allow 4975 1.1.1.3.2.1 yamt zero 4976 1.1.1.3.2.1 yamt length strings during interpreter buffer-to-string conversions. For 4977 1.1.1.3.2.1 yamt example, 4978 1.1 jruoho during the ToDecimalString and ToHexString operators, as well as implicit 4979 1.1 jruoho conversions. Fiodor Suietov, ACPICA BZ 585. 4980 1.1 jruoho 4981 1.1 jruoho Fixed two possible memory leaks in the error exit paths of 4982 1.1.1.3.2.1 yamt AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions 4983 1.1.1.3.2.1 yamt are 4984 1.1 jruoho similar in that they use a stack of state objects in order to eliminate 4985 1.1 jruoho recursion. The stack must be fully unwound and deallocated if an error 4986 1.1 jruoho occurs. Lin Ming. ACPICA BZ 383. 4987 1.1 jruoho 4988 1.1.1.3.2.1 yamt Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the 4989 1.1.1.3.2.1 yamt global 4990 1.1 jruoho ACPI register table. This bit does not exist and is unused. Lin Ming, Bob 4991 1.1 jruoho Moore ACPICA BZ 442. 4992 1.1 jruoho 4993 1.1 jruoho Removed the obsolete version number in module headers. Removed the 4994 1.1.1.3.2.1 yamt "$Revision" number that appeared in each module header. This version 4995 1.1.1.3.2.1 yamt number 4996 1.1.1.3.2.1 yamt was useful under SourceSafe and CVS, but has no meaning under git. It is 4997 1.1.1.3.2.1 yamt not 4998 1.1 jruoho only incorrect, it could also be misleading. 4999 1.1 jruoho 5000 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5001 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Changes include the elimination of cheating on the Object 5020 1.1.1.3.2.1 yamt field 5021 1.1 jruoho for the DdbHandle subtype, addition of a reference class field to 5022 1.1.1.3.2.1 yamt differentiate the various reference types (instead of an AML opcode), and 5023 1.1.1.3.2.1 yamt the 5024 1.1 jruoho cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723 5025 1.1 jruoho 5026 1.1 jruoho Reduce an error to a warning for an incorrect method argument count. 5027 1.1 jruoho Previously aborted with an error if too few arguments were passed to a 5028 1.1.1.3.2.1 yamt control method via the external ACPICA interface. Now issue a warning 5029 1.1.1.3.2.1 yamt instead 5030 1.1.1.3.2.1 yamt and continue. Handles the case where the method inadvertently declares 5031 1.1.1.3.2.1 yamt too 5032 1.1.1.3.2.1 yamt many arguments, but does not actually use the extra ones. Applies mainly 5033 1.1.1.3.2.1 yamt to 5034 1.1 jruoho the predefined methods. Lin Ming. Linux BZ 11032. 5035 1.1 jruoho 5036 1.1.1.3.2.1 yamt Disallow the evaluation of named object types with no intrinsic value. 5037 1.1.1.3.2.1 yamt Return 5038 1.1.1.3.2.1 yamt AE_TYPE for objects that have no value and therefore evaluation is 5039 1.1.1.3.2.1 yamt undefined: 5040 1.1.1.3.2.1 yamt Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation 5041 1.1.1.3.2.1 yamt of 5042 1.1.1.3.2.1 yamt these types were allowed, but an exception would be generated at some 5043 1.1.1.3.2.1 yamt point 5044 1.1 jruoho during the evaluation. Now, the error is generated up front. 5045 1.1 jruoho 5046 1.1 jruoho Fixed a possible memory leak in the AcpiNsGetExternalPathname function 5047 1.1 jruoho (nsnames.c). Fixes a leak in the error exit path. 5048 1.1 jruoho 5049 1.1.1.3.2.1 yamt Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These 5050 1.1.1.3.2.1 yamt debug 5051 1.1.1.3.2.1 yamt levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and 5052 1.1.1.3.2.1 yamt ACPI_EXCEPTION 5053 1.1 jruoho interfaces. Also added ACPI_DB_EVENTS to correspond with the existing 5054 1.1 jruoho ACPI_LV_EVENTS. 5055 1.1 jruoho 5056 1.1 jruoho Removed obsolete and/or unused exception codes from the acexcep.h header. 5057 1.1.1.3.2.1 yamt There is the possibility that certain device drivers may be affected if 5058 1.1.1.3.2.1 yamt they 5059 1.1 jruoho use any of these exceptions. 5060 1.1 jruoho 5061 1.1.1.3.2.1 yamt The ACPICA documentation has been added to the public git source tree, 5062 1.1.1.3.2.1 yamt under 5063 1.1 jruoho acpica/documents.

Summary of changes for version 20080701: 5221 1.1 jruoho 5222 1.1 jruoho 0) Git source tree / acpica.org 5223 1.1 jruoho 5224 1.1 jruoho Fixed a problem where a git-clone from http would not transfer the entire 5225 1.1 jruoho source tree. 5226 1.1 jruoho 5227 1.1 jruoho 1) ACPI CA Core Subsystem: 5228 1.1 jruoho 5229 1.1 jruoho Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one 5230 1.1.1.3.2.1 yamt enable bit. Now performs a read-change-write of the enable register 5231 1.1.1.3.2.1 yamt instead 5232 1.1.1.3.2.1 yamt of simply writing out the cached enable mask. This will prevent 5233 1.1.1.3.2.1 yamt inadvertent 5234 1.1.1.3.2.1 yamt enabling of GPEs if a rogue GPE is received during initialization (before 5235 1.1.1.3.2.1 yamt GPE 5236 1.1 jruoho handlers are installed.) 5237 1.1 jruoho 5238 1.1 jruoho Implemented a copy for dynamically loaded tables. Previously, dynamically 5239 1.1 jruoho loaded tables were simply mapped - but on some machines this memory is 5240 1.1 jruoho corrupted after suspend. Now copy the table to a local buffer. For the 5241 1.1 jruoho OpRegion case, added checksum verify. Use the table length from the table 5242 1.1 jruoho header, not the region length. For the Buffer case, use the table length 5243 1.1 jruoho also. Dennis Noordsij, Bob Moore. BZ 10734 5244 1.1 jruoho 5245 1.1.1.3.2.1 yamt Fixed a problem where the same ACPI table could not be dynamically loaded 5246 1.1.1.3.2.1 yamt and 5247 1.1.1.3.2.1 yamt unloaded more than once. Without this change, a table cannot be loaded 5248 1.1.1.3.2.1 yamt again 5249 1.1 jruoho once it has been loaded/unloaded one time. The current mechanism does not 5250 1.1.1.3.2.1 yamt unregister a table upon an unload. During a load, if the same table is 5251 1.1.1.3.2.1 yamt found, 5252 1.1 jruoho this no longer returns an exception. BZ 722 5253 1.1 jruoho 5254 1.1 jruoho Fixed a problem where the wrong descriptor length was calculated for the 5255 1.1.1.3.2.1 yamt EndTag descriptor in 64-bit mode. The "minimal" descriptors such as 5256 1.1.1.3.2.1 yamt EndTag 5257 1.1 jruoho are calculated as 12 bytes long, but the actual length in the internal 5258 1.1.1.3.2.1 yamt descriptor is 16 because of the round-up to 8 on the 64-bit build. 5259 1.1.1.3.2.1 yamt Reported 5260 1.1 jruoho by Linn Crosetto. BZ 728 5261 1.1 jruoho 5262 1.1.1.3.2.1 yamt Fixed a possible memory leak in the Unload operator. The DdbHandle 5263 1.1.1.3.2.1 yamt returned 5264 1.1.1.3.2.1 yamt by Load() did not have its reference count decremented during unload, 5265 1.1.1.3.2.1 yamt leading 5266 1.1 jruoho to a memory leak. Lin Ming. BZ 727 5267 1.1 jruoho 5268 1.1 jruoho Fixed a possible memory leak when deleting thermal/processor objects. Any 5269 1.1 jruoho associated notify handlers (and objects) were not being deleted. Fiodor 5270 1.1 jruoho Suietov. BZ 506 5271 1.1 jruoho 5272 1.1.1.3.2.1 yamt Fixed the ordering of the ASCII names in the global mutex table to match 5273 1.1.1.3.2.1 yamt the 5274 1.1.1.3.2.1 yamt actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug 5275 1.1.1.3.2.1 yamt only. 5276 1.1 jruoho Vegard Nossum. BZ 726 5277 1.1 jruoho 5278 1.1 jruoho Enhanced the AcpiGetObjectInfo interface to return the number of required 5279 1.1.1.3.2.1 yamt arguments if the object is a control method. Added this call to the 5280 1.1.1.3.2.1 yamt debugger 5281 1.1 jruoho so the proper number of default arguments are passed to a method. This 5282 1.1 jruoho prevents a warning when executing methods from AcpiExec. 5283 1.1 jruoho 5284 1.1 jruoho Added a check for an invalid handle in AcpiGetObjectInfo. Return 5285 1.1 jruoho AE_BAD_PARAMETER if input handle is invalid. BZ 474 5286 1.1 jruoho 5287 1.1 jruoho Fixed an extraneous warning from exconfig.c on the 64-bit build. 5288 1.1 jruoho 5289 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5290 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 5291 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 5292 1.1.1.3.2.1 yamt has a 5293 1.1 jruoho much larger code and data size. 5294 1.1 jruoho 5295 1.1 jruoho Previous Release: 5296 1.1 jruoho Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total 5297 1.1 jruoho Debug Version: 153.0K Code, 48.2K Data, 201.2K Total 5298 1.1 jruoho Current Release: 5299 1.1 jruoho Non-Debug Version: 79.6K Code, 16.2K Data, 95.8K Total 5300 1.1 jruoho Debug Version: 153.5K Code, 48.2K Data, 201.7K Total 5301 1.1 jruoho 5302 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 5303 1.1 jruoho 5304 1.1 jruoho iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both 5305 1.1 jruoho resource descriptor names. 5306 1.1 jruoho 5307 1.1.1.3.2.1 yamt iASL: Detect invalid ASCII characters in input (windows version). Removed 5308 1.1.1.3.2.1 yamt the 5309 1.1 jruoho "-CF" flag from the flex compile, enables correct detection of non-ASCII 5310 1.1 jruoho characters in the input. BZ 441 5311 1.1 jruoho 5312 1.1.1.3.2.1 yamt iASL: Eliminate warning when result of LoadTable is not used. Eliminate 5313 1.1.1.3.2.1 yamt the 5314 1.1 jruoho "result of operation not used" warning when the DDB handle returned from 5315 1.1 jruoho LoadTable is not used. The warning is not needed. BZ 590 5316 1.1 jruoho 5317 1.1.1.3.2.1 yamt AcpiExec: Add support for dynamic table load/unload. Now calls _CFG 5318 1.1.1.3.2.1 yamt method 5319 1.1.1.3.2.1 yamt to 5320 1.1.1.3.2.1 yamt pass address of table to the AML. Added option to disable OpRegion 5321 1.1.1.3.2.1 yamt simulation 5322 1.1.1.3.2.1 yamt to allow creation of an OpRegion with a real address that was passed to 5323 1.1.1.3.2.1 yamt _CFG. 5324 1.1.1.3.2.1 yamt All of this allows testing of the Load and Unload operators from 5325 1.1.1.3.2.1 yamt AcpiExec. 5326 1.1 jruoho 5327 1.1.1.3.2.1 yamt Debugger: update tables command for unloaded tables. Handle unloaded 5328 1.1.1.3.2.1 yamt tables 5329 1.1 jruoho and use the standard table header output routine. 5330 1.1 jruoho 5331 1.1 jruoho ---------------------------------------- 5332 1.1 jruoho 09 June 2008. Summary of changes for version 20080609: 5333 1.1 jruoho 5334 1.1 jruoho 1) ACPI CA Core Subsystem: 5335 1.1 jruoho 5336 1.1.1.3.2.1 yamt Implemented a workaround for reversed _PRT entries. A significant number 5337 1.1.1.3.2.1 yamt of 5338 1.1 jruoho BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This 5339 1.1.1.3.2.1 yamt change dynamically detects and repairs this problem. Provides 5340 1.1.1.3.2.1 yamt compatibility 5341 1.1 jruoho with MS ACPI. BZ 6859 5342 1.1 jruoho 5343 1.1 jruoho Simplified the internal ACPI hardware interfaces to eliminate the locking 5344 1.1 jruoho flag parameter from Register Read/Write. Added a new external interface, 5345 1.1 jruoho AcpiGetRegisterUnlocked. 5346 1.1 jruoho 5347 1.1.1.3.2.1 yamt Fixed a problem where the invocation of a GPE control method could hang. 5348 1.1.1.3.2.1 yamt This 5349 1.1 jruoho was a regression introduced in 20080514. The new method argument count 5350 1.1 jruoho validation mechanism can enter an infinite loop when a GPE method is 5351 1.1.1.3.2.1 yamt dispatched. Problem fixed by removing the obsolete code that passed GPE 5352 1.1.1.3.2.1 yamt block 5353 1.1.1.3.2.1 yamt information to the notify handler via the control method parameter 5354 1.1.1.3.2.1 yamt pointer. 5355 1.1 jruoho 5356 1.1.1.3.2.1 yamt Fixed a problem where the _SST execution status was incorrectly returned 5357 1.1.1.3.2.1 yamt to 5358 1.1.1.3.2.1 yamt the caller of AcpiEnterSleepStatePrep. This was a regression introduced 5359 1.1.1.3.2.1 yamt in 5360 1.1 jruoho 20080514. _SST is optional and a NOT_FOUND exception should never be 5361 1.1 jruoho returned. BZ 716 5362 1.1 jruoho 5363 1.1.1.3.2.1 yamt Fixed a problem where a deleted object could be accessed from within the 5364 1.1.1.3.2.1 yamt AML 5365 1.1.1.3.2.1 yamt parser. This was a regression introduced in version 20080123 as a fix for 5366 1.1.1.3.2.1 yamt the 5367 1.1 jruoho Unload operator. Lin Ming. BZ 10669 5368 1.1 jruoho 5369 1.1.1.3.2.1 yamt Cleaned up the debug operand dump mechanism. Eliminated unnecessary 5370 1.1.1.3.2.1 yamt operands 5371 1.1 jruoho and eliminated the use of a negative index in a loop. Operands are now 5372 1.1.1.3.2.1 yamt displayed in the correct order, not backwards. This also fixes a 5373 1.1.1.3.2.1 yamt regression 5374 1.1 jruoho introduced in 20080514 on 64-bit systems where the elimination of 5375 1.1.1.3.2.1 yamt ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 5376 1.1.1.3.2.1 yamt 715 5377 1.1 jruoho 5378 1.1.1.3.2.1 yamt Fixed a possible memory leak in EvPciConfigRegionSetup where the error 5379 1.1.1.3.2.1 yamt exit 5380 1.1 jruoho path did not delete a locally allocated structure. 5381 1.1 jruoho 5382 1.1 jruoho Updated definitions for the DMAR and SRAT tables to synchronize with the 5383 1.1 jruoho current specifications. Includes disassembler support. 5384 1.1 jruoho 5385 1.1 jruoho Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect 5386 1.1.1.3.2.1 yamt loop termination value was used. Loop terminated on iteration early, 5387 1.1.1.3.2.1 yamt missing 5388 1.1 jruoho one mutex. Linn Crosetto 5389 1.1 jruoho 5390 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5391 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 5392 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 5393 1.1.1.3.2.1 yamt has a 5394 1.1 jruoho much larger code and data size. 5395 1.1 jruoho 5396 1.1 jruoho Previous Release: 5397 1.1 jruoho Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total 5398 1.1 jruoho Debug Version: 153.3K Code, 48.3K Data, 201.6K Total 5399 1.1 jruoho Current Release: 5400 1.1 jruoho Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total 5401 1.1 jruoho Debug Version: 153.0K Code, 48.2K Data, 201.2K Total 5402 1.1 jruoho 5403 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 5404 1.1 jruoho 5405 1.1 jruoho Disassembler: Implemented support for EisaId() within _CID objects. Now 5406 1.1 jruoho disassemble integer _CID objects back to EisaId invocations, including 5407 1.1 jruoho multiple integers within _CID packages. Includes single-step support for 5408 1.1 jruoho debugger also. 5409 1.1 jruoho 5410 1.1 jruoho Disassembler: Added support for DMAR and SRAT table definition changes. 5411 1.1 jruoho 5412 1.1 jruoho ---------------------------------------- 5413 1.1 jruoho 14 May 2008. Summary of changes for version 20080514: 5414 1.1 jruoho 5415 1.1 jruoho 1) ACPI CA Core Subsystem: 5416 1.1 jruoho 5417 1.1 jruoho Fixed a problem where GPEs were enabled too early during the ACPICA 5418 1.1 jruoho initialization. This could lead to "handler not installed" errors on some 5419 1.1.1.3.2.1 yamt machines. Moved GPE enable until after _REG/_STA/_INI methods are run. 5420 1.1.1.3.2.1 yamt This 5421 1.1.1.3.2.1 yamt ensures that all operation regions and devices throughout the namespace 5422 1.1.1.3.2.1 yamt have 5423 1.1 jruoho been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916. 5424 1.1 jruoho 5425 1.1 jruoho Implemented a change to the enter sleep code. Moved execution of the _GTS 5426 1.1.1.3.2.1 yamt method to just before setting sleep enable bit. The execution was moved 5427 1.1.1.3.2.1 yamt from 5428 1.1 jruoho AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed 5429 1.1 jruoho immediately before the SLP_EN bit is set, as per the ACPI specification. 5430 1.1 jruoho Luming Yu, BZ 1653. 5431 1.1 jruoho 5432 1.1.1.3.2.1 yamt Implemented a fix to disable unknown GPEs (2nd version). Now always 5433 1.1.1.3.2.1 yamt disable 5434 1.1 jruoho the GPE, even if ACPICA thinks that that it is already disabled. It is 5435 1.1.1.3.2.1 yamt possible that the AML or some other code has enabled the GPE unbeknownst 5436 1.1.1.3.2.1 yamt to 5437 1.1 jruoho the ACPICA code. 5438 1.1 jruoho 5439 1.1.1.3.2.1 yamt Fixed a problem with the Field operator where zero-length fields would 5440 1.1.1.3.2.1 yamt return 5441 1.1.1.3.2.1 yamt an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length 5442 1.1.1.3.2.1 yamt ASL 5443 1.1 jruoho field declarations in Field(), BankField(), and IndexField(). BZ 10606. 5444 1.1 jruoho 5445 1.1.1.3.2.1 yamt Implemented a fix for the Load operator, now load the table at the 5446 1.1.1.3.2.1 yamt namespace 5447 1.1.1.3.2.1 yamt root. This reverts a change introduced in version 20071019. The table is 5448 1.1.1.3.2.1 yamt now 5449 1.1 jruoho loaded at the namespace root even though this goes against the ACPI 5450 1.1.1.3.2.1 yamt specification. This provides compatibility with other ACPI 5451 1.1.1.3.2.1 yamt implementations. 5452 1.1.1.3.2.1 yamt The ACPI specification will be updated to reflect this in ACPI 4.0. Lin 5453 1.1.1.3.2.1 yamt Ming. 5454 1.1 jruoho 5455 1.1.1.3.2.1 yamt Fixed a problem where ACPICA would not Load() tables with unusual 5456 1.1.1.3.2.1 yamt signatures. 5457 1.1 jruoho Now ignore ACPI table signature for Load() operator. Only "SSDT" is 5458 1.1 jruoho acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. 5459 1.1.1.3.2.1 yamt Therefore, signature validation is worthless. Apparently MS ACPI accepts 5460 1.1.1.3.2.1 yamt such 5461 1.1 jruoho signatures, ACPICA must be compatible. BZ 10454. 5462 1.1 jruoho 5463 1.1.1.3.2.1 yamt Fixed a possible negative array index in AcpiUtValidateException. Added 5464 1.1.1.3.2.1 yamt NULL 5465 1.1.1.3.2.1 yamt fields to the exception string arrays to eliminate a -1 subtraction on 5466 1.1.1.3.2.1 yamt the 5467 1.1 jruoho SubStatus field. 5468 1.1 jruoho 5469 1.1 jruoho Updated the debug tracking macros to reduce overall code and data size. 5470 1.1 jruoho Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings 5471 1.1 jruoho instead of pointers to static strings. Jan Beulich and Bob Moore. 5472 1.1 jruoho 5473 1.1 jruoho Implemented argument count checking in control method invocation via 5474 1.1.1.3.2.1 yamt AcpiEvaluateObject. Now emit an error if too few arguments, warning if 5475 1.1.1.3.2.1 yamt too 5476 1.1.1.3.2.1 yamt many. This applies only to extern programmatic control method execution, 5477 1.1.1.3.2.1 yamt not 5478 1.1 jruoho method-to-method calls within the AML. Lin Ming. 5479 1.1 jruoho 5480 1.1.1.3.2.1 yamt Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is 5481 1.1.1.3.2.1 yamt no 5482 1.1.1.3.2.1 yamt longer needed, especially with the removal of 16-bit support. It was 5483 1.1.1.3.2.1 yamt replaced 5484 1.1.1.3.2.1 yamt mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 5485 1.1.1.3.2.1 yamt bit 5486 1.1.1.3.2.1 yamt on 5487 1.1 jruoho 32/64-bit platforms is required. 5488 1.1 jruoho 5489 1.1 jruoho Added the C const qualifier for appropriate string constants -- mostly 5490 1.1 jruoho MODULE_NAME and printf format strings. Jan Beulich. 5491 1.1 jruoho 5492 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5493 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 5494 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 5495 1.1.1.3.2.1 yamt has a 5496 1.1 jruoho much larger code and data size. 5497 1.1 jruoho 5498 1.1 jruoho Previous Release: 5499 1.1 jruoho Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 5500 1.1 jruoho Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 5501 1.1 jruoho Current Release: 5502 1.1 jruoho Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total 5503 1.1 jruoho Debug Version: 153.3K Code, 48.3K Data, 201.6K Total 5504 1.1 jruoho 5505 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 5506 1.1 jruoho 5507 1.1.1.3.2.1 yamt Implemented ACPI table revision ID validation in the disassembler. Zero 5508 1.1.1.3.2.1 yamt is 5509 1.1.1.3.2.1 yamt always invalid. For DSDTs, the ID controls the interpreter integer width. 5510 1.1.1.3.2.1 yamt 1 5511 1.1 jruoho means 32-bit and this is unusual. 2 or greater is 64-bit. 5512 1.1 jruoho 5513 1.1 jruoho ---------------------------------------- 5514 1.1 jruoho 21 March 2008. Summary of changes for version 20080321: 5515 1.1 jruoho 5516 1.1 jruoho 1) ACPI CA Core Subsystem: 5517 1.1 jruoho 5518 1.1 jruoho Implemented an additional change to the GPE support in order to suppress 5519 1.1.1.3.2.1 yamt spurious or stray GPEs. The AcpiEvDisableGpe function will now 5520 1.1.1.3.2.1 yamt permanently 5521 1.1.1.3.2.1 yamt disable incoming GPEs that are neither enabled nor disabled -- meaning 5522 1.1.1.3.2.1 yamt that 5523 1.1.1.3.2.1 yamt the GPE is unknown to the system. This should prevent future interrupt 5524 1.1.1.3.2.1 yamt floods 5525 1.1 jruoho from that GPE. BZ 6217 (Zhang Rui) 5526 1.1 jruoho 5527 1.1 jruoho Fixed a problem where NULL package elements were not returned to the 5528 1.1 jruoho AcpiEvaluateObject interface correctly. The element was simply ignored 5529 1.1.1.3.2.1 yamt instead of returning a NULL ACPI_OBJECT package element, potentially 5530 1.1.1.3.2.1 yamt causing 5531 1.1.1.3.2.1 yamt a buffer overflow and/or confusing the caller who expected a fixed number 5532 1.1.1.3.2.1 yamt of 5533 1.1 jruoho elements. BZ 10132 (Lin Ming, Bob Moore) 5534 1.1 jruoho 5535 1.1.1.3.2.1 yamt Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, 5536 1.1.1.3.2.1 yamt Dword, 5537 1.1.1.3.2.1 yamt Qword), Field, BankField, and IndexField operators when invoked from 5538 1.1.1.3.2.1 yamt inside 5539 1.1.1.3.2.1 yamt an executing control method. In this case, these operators created 5540 1.1.1.3.2.1 yamt namespace 5541 1.1 jruoho nodes that were incorrectly left marked as permanent nodes instead of 5542 1.1 jruoho temporary nodes. This could cause a problem if there is race condition 5543 1.1.1.3.2.1 yamt between an exiting control method and a running namespace walk. (Reported 5544 1.1.1.3.2.1 yamt by 5545 1.1 jruoho Linn Crosetto) 5546 1.1 jruoho 5547 1.1 jruoho Fixed a problem where the CreateField and CreateXXXField operators would 5548 1.1.1.3.2.1 yamt incorrectly allow duplicate names (the name of the field) with no 5549 1.1.1.3.2.1 yamt exception 5550 1.1 jruoho generated. 5551 1.1 jruoho 5552 1.1.1.3.2.1 yamt Implemented several changes for Notify handling. Added support for new 5553 1.1.1.3.2.1 yamt Notify 5554 1.1 jruoho values (ACPI 2.0+) and improved the Notify debug output. Notify on 5555 1.1.1.3.2.1 yamt PowerResource objects is no longer allowed, as per the ACPI 5556 1.1.1.3.2.1 yamt specification. 5557 1.1 jruoho (Bob Moore, Zhang Rui) 5558 1.1 jruoho 5559 1.1.1.3.2.1 yamt All Reference Objects returned via the AcpiEvaluateObject interface are 5560 1.1.1.3.2.1 yamt now 5561 1.1.1.3.2.1 yamt marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved 5562 1.1.1.3.2.1 yamt for 5563 1.1.1.3.2.1 yamt NULL objects - either NULL package elements or unresolved named 5564 1.1.1.3.2.1 yamt references. 5565 1.1 jruoho 5566 1.1.1.3.2.1 yamt Fixed a problem where an extraneous debug message was produced for 5567 1.1.1.3.2.1 yamt package 5568 1.1 jruoho objects (when debugging enabled). The message "Package List length larger 5569 1.1.1.3.2.1 yamt than NumElements count" is now produced in the correct case, and is now 5570 1.1.1.3.2.1 yamt an 5571 1.1 jruoho error message rather than a debug message. Added a debug message for the 5572 1.1.1.3.2.1 yamt opposite case, where NumElements is larger than the Package List (the 5573 1.1.1.3.2.1 yamt package 5574 1.1 jruoho will be padded out with NULL elements as per the ACPI spec.) 5575 1.1 jruoho 5576 1.1.1.3.2.1 yamt Implemented several improvements for the output of the ASL "Debug" object 5577 1.1.1.3.2.1 yamt to 5578 1.1 jruoho clarify and keep all data for a given object on one output line. 5579 1.1 jruoho 5580 1.1.1.3.2.1 yamt Fixed two size calculation issues with the variable-length Start 5581 1.1.1.3.2.1 yamt Dependent 5582 1.1 jruoho resource descriptor. 5583 1.1 jruoho 5584 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5585 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 5586 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 5587 1.1.1.3.2.1 yamt has 5588 1.1 jruoho a much larger code and data size. 5589 1.1 jruoho 5590 1.1 jruoho Previous Release: 5591 1.1 jruoho Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total 5592 1.1 jruoho Debug Version: 158.9K Code, 64.0K Data, 222.9K Total 5593 1.1 jruoho Current Release: 5594 1.1 jruoho Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 5595 1.1 jruoho Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 5596 1.1 jruoho 5597 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 5598 1.1 jruoho 5599 1.1.1.3.2.1 yamt Fixed a problem with the use of the Switch operator where execution of 5600 1.1.1.3.2.1 yamt the 5601 1.1 jruoho containing method by multiple concurrent threads could cause an 5602 1.1 jruoho AE_ALREADY_EXISTS exception. This is caused by the fact that there is no 5603 1.1 jruoho actual Switch opcode, it must be simulated with local named temporary 5604 1.1.1.3.2.1 yamt variables and if/else pairs. The solution chosen was to mark any method 5605 1.1.1.3.2.1 yamt that 5606 1.1.1.3.2.1 yamt uses Switch as Serialized, thus preventing multiple thread entries. BZ 5607 1.1.1.3.2.1 yamt 469. 5608 1.1 jruoho 5609 1.1 jruoho ---------------------------------------- 5610 1.1 jruoho 13 February 2008. Summary of changes for version 20080213: 5611 1.1 jruoho 5612 1.1 jruoho 1) ACPI CA Core Subsystem: 5613 1.1 jruoho 5614 1.1.1.3.2.1 yamt Implemented another MS compatibility design change for GPE/Notify 5615 1.1.1.3.2.1 yamt handling. 5616 1.1.1.3.2.1 yamt GPEs are now cleared/enabled asynchronously to allow all pending notifies 5617 1.1.1.3.2.1 yamt to 5618 1.1 jruoho complete first. It is expected that the OSL will queue the enable request 5619 1.1.1.3.2.1 yamt behind all pending notify requests (may require changes to the local host 5620 1.1.1.3.2.1 yamt OSL 5621 1.1 jruoho in AcpiOsExecute). Alexey Starikovskiy. 5622 1.1 jruoho 5623 1.1 jruoho Fixed a problem where buffer and package objects passed as arguments to a 5624 1.1.1.3.2.1 yamt control method via the external AcpiEvaluateObject interface could cause 5625 1.1.1.3.2.1 yamt an 5626 1.1 jruoho AE_AML_INTERNAL exception depending on the order and type of operators 5627 1.1 jruoho executed by the target control method. 5628 1.1 jruoho 5629 1.1 jruoho Fixed a problem where resource descriptor size optimization could cause a 5630 1.1.1.3.2.1 yamt problem when a _CRS resource template is passed to a _SRS method. The 5631 1.1.1.3.2.1 yamt _SRS 5632 1.1 jruoho resource template must use the same descriptors (with the same size) as 5633 1.1.1.3.2.1 yamt returned from _CRS. This change affects the following resource 5634 1.1.1.3.2.1 yamt descriptors: 5635 1.1.1.3.2.1 yamt IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 5636 1.1.1.3.2.1 yamt 9487) 5637 1.1.1.3.2.1 yamt 5638 1.1.1.3.2.1 yamt Fixed a problem where a CopyObject to RegionField, BankField, and 5639 1.1.1.3.2.1 yamt IndexField 5640 1.1.1.3.2.1 yamt objects did not perform an implicit conversion as it should. These types 5641 1.1.1.3.2.1 yamt must 5642 1.1.1.3.2.1 yamt retain their initial type permanently as per the ACPI specification. 5643 1.1.1.3.2.1 yamt However, 5644 1.1 jruoho a CopyObject to all other object types should not perform an implicit 5645 1.1 jruoho conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388 5646 1.1 jruoho 5647 1.1 jruoho Fixed a problem with the AcpiGetDevices interface where the mechanism to 5648 1.1 jruoho match device CIDs did not examine the entire list of available CIDs, but 5649 1.1 jruoho instead aborted on the first non-matching CID. Andrew Patterson. 5650 1.1 jruoho 5651 1.1.1.3.2.1 yamt Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro 5652 1.1.1.3.2.1 yamt was 5653 1.1 jruoho inadvertently changed to return a 16-bit value instead of a 32-bit value, 5654 1.1 jruoho truncating the upper dword of a 64-bit value. This macro is only used to 5655 1.1 jruoho display debug output, so no incorrect calculations were made. Also, 5656 1.1 jruoho reimplemented the macro so that a 64-bit shift is not performed by 5657 1.1 jruoho inefficient compilers. 5658 1.1 jruoho 5659 1.1 jruoho Added missing va_end statements that should correspond with each va_start 5660 1.1 jruoho statement. 5661 1.1 jruoho 5662 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5663 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

This affects 5688 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, and 5689 1.1 jruoho the tools/utilities. 5690 1.1 jruoho 5691 1.1.1.3.2.1 yamt Fixed a problem with the SizeOf operator when used with Package and 5692 1.1.1.3.2.1 yamt Buffer 5693 1.1.1.3.2.1 yamt objects. These objects have deferred execution for some arguments, and 5694 1.1.1.3.2.1 yamt the 5695 1.1.1.3.2.1 yamt execution is now completed before the SizeOf is executed. This problem 5696 1.1.1.3.2.1 yamt caused 5697 1.1.1.3.2.1 yamt unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) 5698 1.1.1.3.2.1 yamt BZ 5699 1.1 jruoho 9558 5700 1.1 jruoho 5701 1.1.1.3.2.1 yamt Implemented an enhancement to the interpreter "slack mode".

Lin Ming 5868 1.1 jruoho 5869 1.1.1.3.2.1 yamt Fixed a problem with CopyObject used in conjunction with the Index 5870 1.1.1.3.2.1 yamt operator. 5871 1.1.1.3.2.1 yamt The reference was incorrectly dereferenced before the copy. The reference 5872 1.1.1.3.2.1 yamt is 5873 1.1 jruoho now correctly copied. BZ 5391. Lin Ming 5874 1.1 jruoho 5875 1.1.1.3.2.1 yamt Fixed a problem with Control Method references within Package objects. 5876 1.1.1.3.2.1 yamt These 5877 1.1 jruoho references are now correctly generated. This completes the package 5878 1.1 jruoho construction overhaul that began in version 20071019. 5879 1.1 jruoho 5880 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 5881 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 5882 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 5883 1.1.1.3.2.1 yamt has 5884 1.1 jruoho a much larger code and data size. 5885 1.1 jruoho 5886 1.1 jruoho Previous Release: 5887 1.1 jruoho Non-Debug Version: 78.8K Code, 17.2K Data, 96.0K Total 5888 1.1 jruoho Debug Version: 157.2K Code, 63.4K Data, 220.6K Total 5889 1.1 jruoho Current Release: 5890 1.1 jruoho Non-Debug Version: 79.0K Code, 17.2K Data, 96.2K Total 5891 1.1 jruoho Debug Version: 157.9K Code, 63.6K Data, 221.5K Total 5892 1.1 jruoho 5893 1.1 jruoho 5894 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 5895 1.1 jruoho 5896 1.1 jruoho The AcpiExec utility now installs handlers for all of the predefined 5897 1.1 jruoho Operation Region types. New types supported are: PCI_Config, CMOS, and 5898 1.1 jruoho PCIBARTarget. 5899 1.1 jruoho 5900 1.1.1.3.2.1 yamt Fixed a problem with the 64-bit version of AcpiExec where the extended 5901 1.1.1.3.2.1 yamt (64- 5902 1.1 jruoho bit) address fields for the DSDT and FACS within the FADT were not being 5903 1.1.1.3.2.1 yamt used, causing truncation of the upper 32-bits of these addresses.

Summary of changes for version 20071019: 5909 1.1 jruoho 5910 1.1 jruoho 1) ACPI CA Core Subsystem: 5911 1.1 jruoho 5912 1.1 jruoho Fixed a problem with the Alias operator when the target of the alias is a 5913 1.1.1.3.2.1 yamt named ASL operator that opens a new scope -- Scope, Device, 5914 1.1.1.3.2.1 yamt PowerResource, 5915 1.1 jruoho Processor, and ThermalZone. In these cases, any children of the original 5916 1.1.1.3.2.1 yamt operator could not be accessed via the alias, potentially causing 5917 1.1.1.3.2.1 yamt unexpected 5918 1.1 jruoho AE_NOT_FOUND exceptions. (BZ 9067) 5919 1.1 jruoho 5920 1.1 jruoho Fixed a problem with the Package operator where all named references were 5921 1.1.1.3.2.1 yamt created as object references and left otherwise unresolved. According to 5922 1.1.1.3.2.1 yamt the 5923 1.1.1.3.2.1 yamt ACPI specification, a Package can only contain Data Objects or references 5924 1.1.1.3.2.1 yamt to 5925 1.1 jruoho control methods. The implication is that named references to Data Objects 5926 1.1 jruoho (Integer, Buffer, String, Package, BufferField, Field) should be resolved 5927 1.1 jruoho immediately upon package creation. This is the approach taken with this 5928 1.1 jruoho change. References to all other named objects (Methods, Devices, Scopes, 5929 1.1 jruoho etc.) are all now properly created as reference objects. (BZ 5328) 5930 1.1 jruoho 5931 1.1 jruoho Reverted a change to Notify handling that was introduced in version 5932 1.1 jruoho 20070508. This version changed the Notify handling from asynchronous to 5933 1.1.1.3.2.1 yamt fully synchronous (Device driver Notify handling with respect to the 5934 1.1.1.3.2.1 yamt Notify 5935 1.1 jruoho ASL operator). It was found that this change caused more problems than it 5936 1.1 jruoho solved and was removed by most users. 5937 1.1 jruoho 5938 1.1.1.3.2.1 yamt Fixed a problem with the Increment and Decrement operators where the type 5939 1.1.1.3.2.1 yamt of 5940 1.1 jruoho the target object could be unexpectedly and incorrectly changed. (BZ 353) 5941 1.1 jruoho Lin Ming. 5942 1.1 jruoho 5943 1.1 jruoho Fixed a problem with the Load and LoadTable operators where the table 5944 1.1 jruoho location within the namespace was ignored. Instead, the table was always 5945 1.1 jruoho loaded into the root or current scope. Lin Ming. 5946 1.1 jruoho 5947 1.1 jruoho Fixed a problem with the Load operator when loading a table from a buffer 5948 1.1 jruoho object. The input buffer was prematurely zeroed and/or deleted. (BZ 577) 5949 1.1 jruoho 5950 1.1.1.3.2.1 yamt Fixed a problem with the Debug object where a store of a DdbHandle 5951 1.1.1.3.2.1 yamt reference 5952 1.1 jruoho object to the Debug object could cause a fault. 5953 1.1 jruoho 5954 1.1.1.3.2.1 yamt Added a table checksum verification for the Load operator, in the case 5955 1.1.1.3.2.1 yamt where 5956 1.1 jruoho the load is from a buffer. (BZ 578). 5957 1.1 jruoho 5958 1.1.1.3.2.1 yamt Implemented additional parameter validation for the LoadTable operator. 5959 1.1.1.3.2.1 yamt The 5960 1.1.1.3.2.1 yamt length of the input strings SignatureString, OemIdString, and OemTableId 5961 1.1.1.3.2.1 yamt are 5962 1.1 jruoho now checked for maximum lengths.

Summary of changes for version 20070919: 5986 1.1 jruoho 5987 1.1 jruoho 1) ACPI CA Core Subsystem: 5988 1.1 jruoho 5989 1.1 jruoho Designed and implemented new external interfaces to install and remove 5990 1.1.1.3.2.1 yamt handlers for ACPI table-related events. Current events that are defined 5991 1.1.1.3.2.1 yamt are 5992 1.1 jruoho LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as 5993 1.1 jruoho they are dynamically loaded and unloaded. See AcpiInstallTableHandler and 5994 1.1 jruoho AcpiRemoveTableHandler. (Lin Ming and Bob Moore) 5995 1.1 jruoho 5996 1.1 jruoho Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag 5997 1.1 jruoho (acpi_serialized option on Linux) could cause some systems to hang during 5998 1.1 jruoho initialization. (Bob Moore) BZ 8171 5999 1.1 jruoho 6000 1.1 jruoho Fixed a problem where objects of certain types (Device, ThermalZone, 6001 1.1 jruoho Processor, PowerResource) can be not found if they are declared and 6002 1.1 jruoho referenced from within the same control method (Lin Ming) BZ 341 6003 1.1 jruoho 6004 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6005 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

This includes command line wildcard support for both 6024 1.1.1.3.2.1 yamt the 6025 1.1 jruoho Windows and Unix versions of the compiler. This feature simplifies the 6026 1.1.1.3.2.1 yamt disassembly and compilation of multiple ACPI tables in a single 6027 1.1.1.3.2.1 yamt directory. 6028 1.1 jruoho 6029 1.1 jruoho ---------------------------------------- 6030 1.1 jruoho 08 May 2007. Summary of changes for version 20070508: 6031 1.1 jruoho 6032 1.1 jruoho 1) ACPI CA Core Subsystem: 6033 1.1 jruoho 6034 1.1.1.3.2.1 yamt Implemented a Microsoft compatibility design change for the handling of 6035 1.1.1.3.2.1 yamt the 6036 1.1 jruoho Notify AML operator. Previously, notify handlers were dispatched and 6037 1.1 jruoho executed completely asynchronously in a deferred thread. The new design 6038 1.1.1.3.2.1 yamt still executes the notify handlers in a different thread, but the 6039 1.1.1.3.2.1 yamt original 6040 1.1.1.3.2.1 yamt thread that executed the Notify() now waits at a synchronization point 6041 1.1.1.3.2.1 yamt for 6042 1.1.1.3.2.1 yamt the notify handler to complete. Some machines depend on a synchronous 6043 1.1.1.3.2.1 yamt Notify 6044 1.1 jruoho operator in order to operate correctly. 6045 1.1 jruoho 6046 1.1 jruoho Implemented support to allow Package objects to be passed as method 6047 1.1 jruoho arguments to the external AcpiEvaluateObject interface. Previously, this 6048 1.1 jruoho would return the AE_NOT_IMPLEMENTED exception. This feature had not been 6049 1.1 jruoho implemented since there were no reserved control methods that required it 6050 1.1 jruoho until recently. 6051 1.1 jruoho 6052 1.1.1.3.2.1 yamt Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs 6053 1.1.1.3.2.1 yamt that 6054 1.1 jruoho contained invalid non-zero values in reserved fields could cause later 6055 1.1.1.3.2.1 yamt failures because these fields have meaning in later revisions of the 6056 1.1.1.3.2.1 yamt FADT. 6057 1.1.1.3.2.1 yamt For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The 6058 1.1.1.3.2.1 yamt fields 6059 1.1 jruoho are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.) 6060 1.1 jruoho 6061 1.1.1.3.2.1 yamt Fixed a problem where the Global Lock handle was not properly updated if 6062 1.1.1.3.2.1 yamt a 6063 1.1.1.3.2.1 yamt thread that acquired the Global Lock via executing AML code then 6064 1.1.1.3.2.1 yamt attempted 6065 1.1.1.3.2.1 yamt to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by 6066 1.1.1.3.2.1 yamt Joe 6067 1.1 jruoho Liu. 6068 1.1 jruoho 6069 1.1 jruoho Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list 6070 1.1 jruoho could be corrupted if the interrupt being removed was at the head of the 6071 1.1 jruoho list. Reported by Linn Crosetto. 6072 1.1 jruoho 6073 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6074 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 6075 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 6076 1.1.1.3.2.1 yamt has 6077 1.1 jruoho a much larger code and data size. 6078 1.1 jruoho 6079 1.1 jruoho Previous Release: 6080 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 6081 1.1 jruoho Debug Version: 155.9K Code, 63.1K Data, 219.0K Total 6082 1.1 jruoho Current Release: 6083 1.1 jruoho Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total 6084 1.1 jruoho Debug Version: 156.3K Code, 63.1K Data, 219.4K Total 6085 1.1 jruoho 6086 1.1 jruoho ---------------------------------------- 6087 1.1 jruoho 20 March 2007. Summary of changes for version 20070320: 6088 1.1 jruoho 6089 1.1 jruoho 1) ACPI CA Core Subsystem: 6090 1.1 jruoho 6091 1.1 jruoho Implemented a change to the order of interpretation and evaluation of AML 6092 1.1 jruoho operand objects within the AML interpreter. The interpreter now evaluates 6093 1.1 jruoho operands in the order that they appear in the AML stream (and the 6094 1.1.1.3.2.1 yamt corresponding ASL code), instead of in the reverse order (after the 6095 1.1.1.3.2.1 yamt entire 6096 1.1.1.3.2.1 yamt operand list has been parsed). The previous behavior caused several 6097 1.1.1.3.2.1 yamt subtle 6098 1.1 jruoho incompatibilities with the Microsoft AML interpreter as well as being 6099 1.1 jruoho somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov. 6100 1.1 jruoho 6101 1.1.1.3.2.1 yamt Implemented a change to the ACPI Global Lock support. All interfaces to 6102 1.1.1.3.2.1 yamt the 6103 1.1 jruoho global lock now allow the same thread to acquire the lock multiple times. 6104 1.1.1.3.2.1 yamt This affects the AcpiAcquireGlobalLock external interface to the global 6105 1.1.1.3.2.1 yamt lock 6106 1.1 jruoho as well as the internal use of the global lock to support AML fields -- a 6107 1.1.1.3.2.1 yamt control method that is holding the global lock can now simultaneously 6108 1.1.1.3.2.1 yamt access 6109 1.1.1.3.2.1 yamt AML fields that require global lock protection. Previously, in both 6110 1.1.1.3.2.1 yamt cases, 6111 1.1.1.3.2.1 yamt this would have resulted in an AE_ALREADY_ACQUIRED exception. The change 6112 1.1.1.3.2.1 yamt to 6113 1.1 jruoho AcpiAcquireGlobalLock is of special interest to drivers for the Embedded 6114 1.1.1.3.2.1 yamt Controller. There is no change to the behavior of the AML Acquire 6115 1.1.1.3.2.1 yamt operator, 6116 1.1 jruoho as this can already be used to acquire a mutex multiple times by the same 6117 1.1 jruoho thread. BZ 8066. With assistance from Alexey Starikovskiy. 6118 1.1 jruoho 6119 1.1 jruoho Fixed a problem where invalid objects could be referenced in the AML 6120 1.1.1.3.2.1 yamt Interpreter after error conditions. During operand evaluation, ensure 6121 1.1.1.3.2.1 yamt that 6122 1.1 jruoho the internal "Return Object" field is cleared on error and only valid 6123 1.1.1.3.2.1 yamt pointers are stored there. Caused occasional access to deleted objects 6124 1.1.1.3.2.1 yamt that 6125 1.1 jruoho resulted in "large reference count" warning messages. Valery Podrezov. 6126 1.1 jruoho 6127 1.1.1.3.2.1 yamt Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur 6128 1.1.1.3.2.1 yamt on 6129 1.1 jruoho deeply nested control method invocations. BZ 7873, local BZ 487. Valery 6130 1.1 jruoho Podrezov. 6131 1.1 jruoho 6132 1.1 jruoho Fixed an internal problem with the handling of result objects on the 6133 1.1 jruoho interpreter result stack. BZ 7872. Valery Podrezov. 6134 1.1 jruoho 6135 1.1.1.3.2.1 yamt Removed obsolete code that handled the case where AML_NAME_OP is the 6136 1.1.1.3.2.1 yamt target 6137 1.1 jruoho of a reference (Reference.Opcode). This code was no longer necessary. BZ 6138 1.1 jruoho 7874. Valery Podrezov. 6139 1.1 jruoho 6140 1.1.1.3.2.1 yamt Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This 6141 1.1.1.3.2.1 yamt was 6142 1.1.1.3.2.1 yamt a 6143 1.1 jruoho remnant from the previously discontinued 16-bit support. 6144 1.1 jruoho 6145 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6146 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 6147 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 6148 1.1.1.3.2.1 yamt has 6149 1.1 jruoho a much larger code and data size. 6150 1.1 jruoho 6151 1.1 jruoho Previous Release: 6152 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 6153 1.1 jruoho Debug Version: 155.8K Code, 63.3K Data, 219.1K Total 6154 1.1 jruoho Current Release: 6155 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 6156 1.1 jruoho Debug Version: 155.9K Code, 63.1K Data, 219.0K Total 6157 1.1 jruoho 6158 1.1 jruoho ---------------------------------------- 6159 1.1 jruoho 26 January 2007.

All 16-bit macros, types, and 6193 1.1.1.3.2.1 yamt conditional compiles have been removed, cleaning up and simplifying the 6194 1.1.1.3.2.1 yamt code 6195 1.1 jruoho across the entire subsystem. DOS support is no longer needed since the 6196 1.1 jruoho bootable Linux firmware kit is now available. 6197 1.1 jruoho 6198 1.1 jruoho The handler for the Global Lock is now removed during AcpiTerminate to 6199 1.1 jruoho enable a clean subsystem restart, via the implementation of the 6200 1.1 jruoho AcpiEvRemoveGlobalLockHandler function. (With assistance from Joel Bretz, 6201 1.1 jruoho HP) 6202 1.1 jruoho 6203 1.1.1.3.2.1 yamt Implemented enhancements to the multithreading support within the 6204 1.1.1.3.2.1 yamt debugger 6205 1.1.1.3.2.1 yamt to enable improved multithreading debugging and evaluation of the 6206 1.1.1.3.2.1 yamt subsystem. 6207 1.1 jruoho (Valery Podrezov) 6208 1.1 jruoho 6209 1.1.1.3.2.1 yamt Debugger: Enhanced the Statistics/Memory command to emit the total 6210 1.1.1.3.2.1 yamt (maximum) 6211 1.1.1.3.2.1 yamt memory used during the execution, as well as the maximum memory consumed 6212 1.1.1.3.2.1 yamt by 6213 1.1 jruoho each of the various object types.

Simply map the operation region memory, instead of 6242 1.1 jruoho performing a bytewise read. (Region must be of type SystemMemory, see 6243 1.1 jruoho below.) 6244 1.1 jruoho 6245 1.1 jruoho Fixed the Load ASL operator for the case where the source operand is a 6246 1.1.1.3.2.1 yamt region field. A buffer object is also allowed as the source operand. BZ 6247 1.1.1.3.2.1 yamt 480 6248 1.1 jruoho 6249 1.1.1.3.2.1 yamt Fixed a problem where the Load ASL operator allowed the source operand to 6250 1.1.1.3.2.1 yamt be 6251 1.1 jruoho an operation region of any type. It is now restricted to regions of type 6252 1.1 jruoho SystemMemory, as per the ACPI specification. BZ 481 6253 1.1 jruoho 6254 1.1 jruoho Additional cleanup and optimizations for the new Table Manager code. 6255 1.1 jruoho 6256 1.1.1.3.2.1 yamt AcpiEnable will now fail if all of the required ACPI tables are not 6257 1.1.1.3.2.1 yamt loaded 6258 1.1 jruoho (FADT, FACS, DSDT). BZ 477 6259 1.1 jruoho 6260 1.1.1.3.2.1 yamt Added #pragma pack(8/4) to acobject.h to ensure that the structures in 6261 1.1.1.3.2.1 yamt this 6262 1.1 jruoho header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been 6263 1.1 jruoho manually optimized to be aligned and will not work if it is byte-packed. 6264 1.1 jruoho 6265 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6266 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Previously a 2-pass parse/execution, control methods are now 6294 1.1 jruoho completely parsed and executed in a single pass. This improves overall 6295 1.1 jruoho interpreter performance by ~25%, reduces code size, and reduces CPU stack 6296 1.1 jruoho use. (Valery Podrezov + interpreter changes in version 20051202 that 6297 1.1 jruoho eliminated namespace loading during the pass one parse.) 6298 1.1 jruoho 6299 1.1.1.3.2.1 yamt Implemented _CID support for PCI Root Bridge detection. If the _HID does 6300 1.1.1.3.2.1 yamt not 6301 1.1.1.3.2.1 yamt match the predefined PCI Root Bridge IDs, the _CID list (if present) is 6302 1.1.1.3.2.1 yamt now 6303 1.1 jruoho obtained and also checked for an ID match. 6304 1.1 jruoho 6305 1.1.1.3.2.1 yamt Implemented additional support for the PCI _ADR execution: upsearch until 6306 1.1.1.3.2.1 yamt a 6307 1.1 jruoho device scope is found before executing _ADR. This allows PCI_Config 6308 1.1.1.3.2.1 yamt operation regions to be declared locally within control methods 6309 1.1.1.3.2.1 yamt underneath 6310 1.1 jruoho PCI device objects. 6311 1.1 jruoho 6312 1.1 jruoho Fixed a problem with a possible race condition between threads executing 6313 1.1 jruoho AcpiWalkNamespace and the AML interpreter. This condition was removed by 6314 1.1.1.3.2.1 yamt modifying AcpiWalkNamespace to (by default) ignore all temporary 6315 1.1.1.3.2.1 yamt namespace 6316 1.1 jruoho entries created during any concurrent control method execution. An 6317 1.1 jruoho additional namespace race condition is known to exist between 6318 1.1 jruoho AcpiWalkNamespace and the Load/Unload ASL operators and is still under 6319 1.1 jruoho investigation. 6320 1.1 jruoho 6321 1.1 jruoho Restructured the AML ParseLoop function, breaking it into several 6322 1.1.1.3.2.1 yamt subfunctions in order to reduce CPU stack use and improve 6323 1.1.1.3.2.1 yamt maintainability. 6324 1.1 jruoho (Mikhail Kouzmich) 6325 1.1 jruoho 6326 1.1.1.3.2.1 yamt AcpiGetHandle: Fix for parameter validation to detect invalid 6327 1.1.1.3.2.1 yamt combinations 6328 1.1 jruoho of prefix handle and pathname.

When this mode is 6412 1.1.1.3.2.1 yamt specified, instead of creating a serialization semaphore per control 6413 1.1.1.3.2.1 yamt method, 6414 1.1 jruoho the interpreter lock is simply no longer released before a blocking 6415 1.1 jruoho operation during control method execution. This effectively makes the AML 6416 1.1 jruoho Interpreter single-threaded. The overhead of a semaphore per-method is 6417 1.1 jruoho eliminated. 6418 1.1 jruoho 6419 1.1.1.3.2.1 yamt Fixed a regression where an error was no longer emitted if a control 6420 1.1.1.3.2.1 yamt method 6421 1.1 jruoho attempts to create 2 objects of the same name. This once again returns 6422 1.1.1.3.2.1 yamt AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism 6423 1.1.1.3.2.1 yamt that 6424 1.1 jruoho will dynamically serialize the control method to possible prevent future 6425 1.1 jruoho errors. (BZ 440) 6426 1.1 jruoho 6427 1.1 jruoho Integrated a fix for a problem with PCI Express HID detection in the PCI 6428 1.1 jruoho Config Space setup procedure. (BZ 7145) 6429 1.1 jruoho 6430 1.1 jruoho Moved all FADT-related functions to a new file, tbfadt.c.

Summary of changes for version 20060823: 6532 1.1 jruoho 6533 1.1 jruoho 1) ACPI CA Core Subsystem: 6534 1.1 jruoho 6535 1.1 jruoho The Table Manager component has been completely redesigned and 6536 1.1.1.3.2.1 yamt reimplemented. The new design is much simpler, and reduces the overall 6537 1.1.1.3.2.1 yamt code 6538 1.1.1.3.2.1 yamt and data size of the kernel-resident ACPICA by approximately 5%. Also, it 6539 1.1.1.3.2.1 yamt is 6540 1.1 jruoho now possible to obtain the ACPI tables very early during kernel 6541 1.1 jruoho initialization, even before dynamic memory management is initialized. 6542 1.1 jruoho (Alexey Starikovskiy, Fiodor Suietov, Bob Moore) 6543 1.1 jruoho 6544 1.1 jruoho Obsolete ACPICA interfaces: 6545 1.1 jruoho 6546 1.1.1.3.2.1 yamt - AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel 6547 1.1.1.3.2.1 yamt init 6548 1.1 jruoho time). 6549 1.1 jruoho - AcpiLoadTable: Not needed. 6550 1.1 jruoho - AcpiUnloadTable: Not needed. 6551 1.1 jruoho 6552 1.1 jruoho New ACPICA interfaces: 6553 1.1 jruoho 6554 1.1.1.3.2.1 yamt - AcpiInitializeTables: Must be called before the table manager can be 6555 1.1.1.3.2.1 yamt used. 6556 1.1 jruoho - AcpiReallocateRootTable: Used to transfer the root table to dynamically 6557 1.1 jruoho allocated memory after it becomes available. 6558 1.1.1.3.2.1 yamt - AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI 6559 1.1.1.3.2.1 yamt tables 6560 1.1 jruoho in the RSDT/XSDT. 6561 1.1 jruoho 6562 1.1 jruoho Other ACPICA changes: 6563 1.1 jruoho 6564 1.1.1.3.2.1 yamt - AcpiGetTableHeader returns the actual mapped table header, not a copy. 6565 1.1.1.3.2.1 yamt Use 6566 1.1 jruoho AcpiOsUnmapMemory to free this mapping. 6567 1.1 jruoho - AcpiGetTable returns the actual mapped table. The mapping is managed 6568 1.1 jruoho internally and must not be deleted by the caller. Use of this interface 6569 1.1 jruoho causes no additional dynamic memory allocation. 6570 1.1.1.3.2.1 yamt - AcpiFindRootPointer: Support for physical addressing has been 6571 1.1.1.3.2.1 yamt eliminated, 6572 1.1 jruoho it appeared to be unused. 6573 1.1 jruoho - The interface to AcpiOsMapMemory has changed to be consistent with the 6574 1.1 jruoho other allocation interfaces. 6575 1.1.1.3.2.1 yamt - The interface to AcpiOsGetRootPointer has changed to eliminate 6576 1.1.1.3.2.1 yamt unnecessary 6577 1.1 jruoho parameters. 6578 1.1.1.3.2.1 yamt - ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 6579 1.1.1.3.2.1 yamt 64- 6580 1.1 jruoho bit platforms. Was previously 64 bits on all platforms. 6581 1.1.1.3.2.1 yamt - The interface to the ACPI Global Lock acquire/release macros have 6582 1.1.1.3.2.1 yamt changed 6583 1.1 jruoho slightly since ACPICA no longer keeps a local copy of the FACS with a 6584 1.1 jruoho constructed pointer to the actual global lock. 6585 1.1 jruoho 6586 1.1 jruoho Porting to the new table manager: 6587 1.1 jruoho 6588 1.1 jruoho - AcpiInitializeTables: Must be called once, and can be called anytime 6589 1.1.1.3.2.1 yamt during the OS initialization process. It allows the host to specify an 6590 1.1.1.3.2.1 yamt area 6591 1.1 jruoho of memory to be used to store the internal version of the RSDT/XSDT (root 6592 1.1.1.3.2.1 yamt table). This allows the host to access ACPI tables before memory 6593 1.1.1.3.2.1 yamt management 6594 1.1 jruoho is initialized and running. 6595 1.1.1.3.2.1 yamt - AcpiReallocateRootTable: Can be called after memory management is 6596 1.1.1.3.2.1 yamt running 6597 1.1 jruoho to copy the root table to a dynamically allocated array, freeing up the 6598 1.1 jruoho scratch memory specified in the call to AcpiInitializeTables. 6599 1.1 jruoho - AcpiSubsystemInitialize: This existing interface is independent of the 6600 1.1.1.3.2.1 yamt Table Manager, and does not have to be called before the Table Manager 6601 1.1.1.3.2.1 yamt can 6602 1.1 jruoho be used, it only must be called before the rest of ACPICA can be used. 6603 1.1.1.3.2.1 yamt - ACPI Tables: Some changes have been made to the names and structure of 6604 1.1.1.3.2.1 yamt the 6605 1.1.1.3.2.1 yamt actbl.h and actbl1.h header files and may require changes to existing 6606 1.1.1.3.2.1 yamt code. 6607 1.1.1.3.2.1 yamt For example, bitfields have been completely removed because of their lack 6608 1.1.1.3.2.1 yamt of 6609 1.1 jruoho portability across C compilers. 6610 1.1 jruoho - Update interfaces to the Global Lock acquire/release macros if local 6611 1.1 jruoho versions are used. (see acwin.h) 6612 1.1 jruoho 6613 1.1 jruoho Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c 6614 1.1 jruoho 6615 1.1 jruoho New files: tbfind.c 6616 1.1 jruoho 6617 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6618 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 6619 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 6620 1.1.1.3.2.1 yamt has 6621 1.1 jruoho a much larger code and data size. 6622 1.1 jruoho 6623 1.1 jruoho Previous Release: 6624 1.1 jruoho Non-Debug Version: 80.7K Code, 17.9K Data, 98.6K Total 6625 1.1 jruoho Debug Version: 161.0K Code, 65.1K Data, 226.1K Total 6626 1.1 jruoho Current Release: 6627 1.1 jruoho Non-Debug Version: 77.8K Code, 16.5K Data, 94.3K Total 6628 1.1 jruoho Debug Version: 154.6K Code, 62.3K Data, 216.9K Total 6629 1.1 jruoho 6630 1.1 jruoho 6631 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 6632 1.1 jruoho 6633 1.1 jruoho No changes for this release. 6634 1.1 jruoho 6635 1.1 jruoho ---------------------------------------- 6636 1.1 jruoho 21 July 2006. Summary of changes for version 20060721: 6637 1.1 jruoho 6638 1.1 jruoho 1) ACPI CA Core Subsystem: 6639 1.1 jruoho 6640 1.1 jruoho The full source code for the ASL test suite used to validate the iASL 6641 1.1 jruoho compiler and the ACPICA core subsystem is being released with the ACPICA 6642 1.1.1.3.2.1 yamt source for the first time. The source is contained in a separate package 6643 1.1.1.3.2.1 yamt and 6644 1.1.1.3.2.1 yamt consists of over 1100 files that exercise all ASL/AML operators. The 6645 1.1.1.3.2.1 yamt package 6646 1.1.1.3.2.1 yamt should appear on the Intel/ACPI web site shortly. (Valery Podrezov, 6647 1.1.1.3.2.1 yamt Fiodor 6648 1.1 jruoho Suietov) 6649 1.1 jruoho 6650 1.1 jruoho Completed a new design and implementation for support of the ACPI Global 6651 1.1 jruoho Lock. On the OS side, the global lock is now treated as a standard AML 6652 1.1 jruoho mutex. Previously, multiple OS threads could "acquire" the global lock 6653 1.1.1.3.2.1 yamt simultaneously. However, this could cause the BIOS to be starved out of 6654 1.1.1.3.2.1 yamt the 6655 1.1 jruoho lock - especially in cases such as the Embedded Controller driver where 6656 1.1 jruoho there is a tight coupling between the OS and the BIOS. 6657 1.1 jruoho 6658 1.1 jruoho Implemented an optimization for the ACPI Global Lock interrupt mechanism. 6659 1.1 jruoho The Global Lock interrupt handler no longer queues the execution of a 6660 1.1.1.3.2.1 yamt separate thread to signal the global lock semaphore. Instead, the 6661 1.1.1.3.2.1 yamt semaphore 6662 1.1 jruoho is signaled directly from the interrupt handler. 6663 1.1 jruoho 6664 1.1 jruoho Implemented support within the AML interpreter for package objects that 6665 1.1.1.3.2.1 yamt contain a larger AML length (package list length) than the package 6666 1.1.1.3.2.1 yamt element 6667 1.1 jruoho count. In this case, the length of the package is truncated to match the 6668 1.1.1.3.2.1 yamt package element count. Some BIOS code apparently modifies the package 6669 1.1.1.3.2.1 yamt length 6670 1.1.1.3.2.1 yamt on the fly, and this change supports this behavior. Provides 6671 1.1.1.3.2.1 yamt compatibility 6672 1.1 jruoho with the MS AML interpreter. (With assistance from Fiodor Suietov) 6673 1.1 jruoho 6674 1.1.1.3.2.1 yamt Implemented a temporary fix for the BankValue parameter of a Bank Field 6675 1.1.1.3.2.1 yamt to 6676 1.1 jruoho support all constant values, now including the Zero and One opcodes. 6677 1.1.1.3.2.1 yamt Evaluation of this parameter must eventually be converted to a full 6678 1.1.1.3.2.1 yamt TermArg 6679 1.1.1.3.2.1 yamt evaluation. A not-implemented error is now returned (temporarily) for 6680 1.1.1.3.2.1 yamt non- 6681 1.1 jruoho constant values for this parameter. 6682 1.1 jruoho 6683 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 6684 1.1.1.3.2.1 yamt - Fix for premature object deletion after CopyObject on Operation Region 6685 1.1.1.3.2.1 yamt (BZ 6686 1.1 jruoho 350) 6687 1.1 jruoho 6688 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6689 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 6690 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 6691 1.1.1.3.2.1 yamt has 6692 1.1 jruoho a much larger code and data size. 6693 1.1 jruoho 6694 1.1 jruoho Previous Release: 6695 1.1 jruoho Non-Debug Version: 80.7K Code, 18.0K Data, 98.7K Total 6696 1.1 jruoho Debug Version: 160.9K Code, 65.1K Data, 226.0K Total 6697 1.1 jruoho Current Release: 6698 1.1 jruoho Non-Debug Version: 80.7K Code, 17.9K Data, 98.6K Total 6699 1.1 jruoho Debug Version: 161.0K Code, 65.1K Data, 226.1K Total 6700 1.1 jruoho 6701 1.1 jruoho 6702 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 6703 1.1 jruoho 6704 1.1 jruoho No changes for this release. 6705 1.1 jruoho 6706 1.1 jruoho ---------------------------------------- 6707 1.1 jruoho 07 July 2006. Summary of changes for version 20060707: 6708 1.1 jruoho 6709 1.1 jruoho 1) ACPI CA Core Subsystem: 6710 1.1 jruoho 6711 1.1 jruoho Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers 6712 1.1 jruoho that do not allow the initialization of address pointers within packed 6713 1.1 jruoho structures - even though the hardware itself may support misaligned 6714 1.1 jruoho transfers. Some of the debug data structures are packed by default to 6715 1.1 jruoho minimize size. 6716 1.1 jruoho 6717 1.1.1.3.2.1 yamt Added an error message for the case where AcpiOsGetThreadId() returns 6718 1.1.1.3.2.1 yamt zero. 6719 1.1 jruoho A non-zero value is required by the core ACPICA code to ensure the proper 6720 1.1 jruoho operation of AML mutexes and recursive control methods. 6721 1.1 jruoho 6722 1.1 jruoho The DSDT is now the only ACPI table that determines whether the AML 6723 1.1.1.3.2.1 yamt interpreter is in 32-bit or 64-bit mode. Not really a functional change, 6724 1.1.1.3.2.1 yamt but 6725 1.1.1.3.2.1 yamt the hooks for per-table 32/64 switching have been removed from the code. 6726 1.1.1.3.2.1 yamt A 6727 1.1 jruoho clarification to the ACPI specification is forthcoming in ACPI 3.0B. 6728 1.1 jruoho 6729 1.1 jruoho Fixed a possible leak of an OwnerID in the error path of 6730 1.1 jruoho AcpiTbInitTableDescriptor (tbinstal.c), and migrated all table OwnerID 6731 1.1.1.3.2.1 yamt deletion to a single place in AcpiTbUninstallTable to correct possible 6732 1.1.1.3.2.1 yamt leaks 6733 1.1 jruoho when using the AcpiTbDeleteTablesByType interface (with assistance from 6734 1.1 jruoho Lance Ortiz.) 6735 1.1 jruoho 6736 1.1 jruoho Fixed a problem with Serialized control methods where the semaphore 6737 1.1 jruoho associated with the method could be over-signaled after multiple method 6738 1.1 jruoho invocations. 6739 1.1 jruoho 6740 1.1.1.3.2.1 yamt Fixed two issues with the locking of the internal namespace data 6741 1.1.1.3.2.1 yamt structure. 6742 1.1 jruoho Both the Unload() operator and AcpiUnloadTable interface now lock the 6743 1.1 jruoho namespace during the namespace deletion associated with the table unload 6744 1.1 jruoho (with assistance from Linn Crosetto.) 6745 1.1 jruoho 6746 1.1 jruoho Fixed problem reports (Valery Podrezov) integrated: 6747 1.1 jruoho - Eliminate unnecessary memory allocation for CreateXxxxField (BZ 5426) 6748 1.1 jruoho 6749 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 6750 1.1 jruoho - Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369) 6751 1.1 jruoho - On Address Space handler deletion, needless deactivation call (BZ 374) 6752 1.1.1.3.2.1 yamt - AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 6753 1.1.1.3.2.1 yamt 375) 6754 1.1.1.3.2.1 yamt - Possible memory leak, Notify sub-objects of Processor, Power, 6755 1.1.1.3.2.1 yamt ThermalZone 6756 1.1 jruoho (BZ 376) 6757 1.1 jruoho - AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378) 6758 1.1 jruoho - Minimum Length of RSDT should be validated (BZ 379) 6759 1.1 jruoho - AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no 6760 1.1 jruoho Handler (BZ (380) 6761 1.1.1.3.2.1 yamt - AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type 6762 1.1.1.3.2.1 yamt loaded 6763 1.1 jruoho (BZ 381) 6764 1.1 jruoho 6765 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6766 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20060623: 6787 1.1 jruoho 6788 1.1 jruoho 1) ACPI CA Core Subsystem: 6789 1.1 jruoho 6790 1.1 jruoho Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This 6791 1.1 jruoho allows the type to be customized to the host OS for improved efficiency 6792 1.1 jruoho (since a spinlock is usually a very small object.) 6793 1.1 jruoho 6794 1.1.1.3.2.1 yamt Implemented support for "ignored" bits in the ACPI registers. According 6795 1.1.1.3.2.1 yamt to 6796 1.1 jruoho the ACPI specification, these bits should be preserved when writing the 6797 1.1.1.3.2.1 yamt registers via a read/modify/write cycle. There are 3 bits preserved in 6798 1.1.1.3.2.1 yamt this 6799 1.1 jruoho manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. 6800 1.1 jruoho 6801 1.1.1.3.2.1 yamt Implemented the initial deployment of new OSL mutex interfaces. Since 6802 1.1.1.3.2.1 yamt some 6803 1.1 jruoho host operating systems have separate mutex and semaphore objects, this 6804 1.1 jruoho feature was requested. The base code now uses mutexes (and the new mutex 6805 1.1 jruoho interfaces) wherever a binary semaphore was used previously. However, for 6806 1.1.1.3.2.1 yamt the current release, the mutex interfaces are defined as macros to map 6807 1.1.1.3.2.1 yamt them 6808 1.1.1.3.2.1 yamt to the existing semaphore interfaces. Therefore, no OSL changes are 6809 1.1.1.3.2.1 yamt required 6810 1.1 jruoho at this time. (See acpiosxf.h) 6811 1.1 jruoho 6812 1.1 jruoho Fixed several problems with the support for the control method SyncLevel 6813 1.1.1.3.2.1 yamt parameter. The SyncLevel now works according to the ACPI specification 6814 1.1.1.3.2.1 yamt and 6815 1.1.1.3.2.1 yamt in concert with the Mutex SyncLevel parameter, since the current 6816 1.1.1.3.2.1 yamt SyncLevel 6817 1.1.1.3.2.1 yamt is a property of the executing thread. Mutual exclusion for control 6818 1.1.1.3.2.1 yamt methods 6819 1.1 jruoho is now implemented with a mutex instead of a semaphore. 6820 1.1 jruoho 6821 1.1 jruoho Fixed three instances of the use of the C shift operator in the bitfield 6822 1.1.1.3.2.1 yamt support code (exfldio.c) to avoid the use of a shift value larger than 6823 1.1.1.3.2.1 yamt the 6824 1.1.1.3.2.1 yamt target data width. The behavior of C compilers is undefined in this case 6825 1.1.1.3.2.1 yamt and 6826 1.1.1.3.2.1 yamt can cause unpredictable results, and therefore the case must be detected 6827 1.1.1.3.2.1 yamt and 6828 1.1 jruoho avoided. (Fiodor Suietov) 6829 1.1 jruoho 6830 1.1 jruoho Added an info message whenever an SSDT or OEM table is loaded dynamically 6831 1.1.1.3.2.1 yamt via the Load() or LoadTable() ASL operators. This should improve 6832 1.1.1.3.2.1 yamt debugging 6833 1.1.1.3.2.1 yamt capability since it will show exactly what tables have been loaded 6834 1.1.1.3.2.1 yamt (beyond 6835 1.1 jruoho the tables present in the RSDT/XSDT.) 6836 1.1 jruoho 6837 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 6838 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20060608: 6857 1.1 jruoho 6858 1.1 jruoho 1) ACPI CA Core Subsystem: 6859 1.1 jruoho 6860 1.1.1.3.2.1 yamt Converted the locking mutex used for the ACPI hardware to a spinlock. 6861 1.1.1.3.2.1 yamt This 6862 1.1 jruoho change should eliminate all problems caused by attempting to acquire a 6863 1.1 jruoho semaphore at interrupt level, and it means that all ACPICA external 6864 1.1.1.3.2.1 yamt interfaces that directly access the ACPI hardware can be safely called 6865 1.1.1.3.2.1 yamt from 6866 1.1.1.3.2.1 yamt interrupt level. OSL code that implements the semaphore interfaces should 6867 1.1.1.3.2.1 yamt be 6868 1.1 jruoho able to eliminate any workarounds for being called at interrupt level. 6869 1.1 jruoho 6870 1.1 jruoho Fixed a regression introduced in 20060526 where the ACPI device 6871 1.1.1.3.2.1 yamt initialization could be prematurely aborted with an AE_NOT_FOUND if a 6872 1.1.1.3.2.1 yamt device 6873 1.1 jruoho did not have an optional _INI method. 6874 1.1 jruoho 6875 1.1 jruoho Fixed an IndexField issue where a write to the Data Register should be 6876 1.1.1.3.2.1 yamt limited in size to the AccessSize (width) of the IndexField itself.

Summary of changes for version 20060526: 6916 1.1 jruoho 6917 1.1 jruoho 1) ACPI CA Core Subsystem: 6918 1.1 jruoho 6919 1.1 jruoho Restructured, flattened, and simplified the internal interfaces for 6920 1.1.1.3.2.1 yamt namespace object evaluation - resulting in smaller code, less CPU stack 6921 1.1.1.3.2.1 yamt use, 6922 1.1 jruoho and fewer interfaces. (With assistance from Mikhail Kouzmich) 6923 1.1 jruoho 6924 1.1.1.3.2.1 yamt Fixed a problem with the CopyObject operator where the first parameter 6925 1.1.1.3.2.1 yamt was 6926 1.1.1.3.2.1 yamt not typed correctly for the parser, interpreter, compiler, and 6927 1.1.1.3.2.1 yamt disassembler. 6928 1.1 jruoho Caused various errors and unexpected behavior. 6929 1.1 jruoho 6930 1.1 jruoho Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits 6931 1.1 jruoho produced incorrect results with some C compilers. Since the behavior of C 6932 1.1 jruoho compilers when the shift value is larger than the datatype width is 6933 1.1.1.3.2.1 yamt apparently not well defined, the interpreter now detects this condition 6934 1.1.1.3.2.1 yamt and 6935 1.1 jruoho simply returns zero as expected in all such cases.

This provides compatibility with other ASL compilers and is 6976 1.1.1.3.2.1 yamt most useful for disassembly/recompilation of existing tables without 6977 1.1.1.3.2.1 yamt parse 6978 1.1 jruoho errors. (With assistance from Thomas Renninger) 6979 1.1 jruoho 6980 1.1 jruoho Disassembler: fixed an incorrect disassembly problem with the 6981 1.1 jruoho DataTableRegion and CopyObject operators. Fixed a possible fault during 6982 1.1 jruoho disassembly of some Alias operators. 6983 1.1 jruoho 6984 1.1 jruoho ---------------------------------------- 6985 1.1 jruoho 12 May 2006. Summary of changes for version 20060512: 6986 1.1 jruoho 6987 1.1 jruoho 1) ACPI CA Core Subsystem: 6988 1.1 jruoho 6989 1.1 jruoho Replaced the AcpiOsQueueForExecution interface with a new interface named 6990 1.1.1.3.2.1 yamt AcpiOsExecute. The major difference is that the new interface does not 6991 1.1.1.3.2.1 yamt have 6992 1.1.1.3.2.1 yamt a Priority parameter, this appeared to be useless and has been replaced 6993 1.1.1.3.2.1 yamt by 6994 1.1.1.3.2.1 yamt a 6995 1.1 jruoho Type parameter. The Type tells the host what type of execution is being 6996 1.1 jruoho requested, such as global lock handler, notify handler, GPE handler, etc. 6997 1.1.1.3.2.1 yamt This allows the host to queue and execute the request as appropriate for 6998 1.1.1.3.2.1 yamt the 6999 1.1.1.3.2.1 yamt request type, possibly using different work queues and different 7000 1.1.1.3.2.1 yamt priorities 7001 1.1 jruoho for the various request types. This enables fixes for multithreading 7002 1.1.1.3.2.1 yamt deadlock problems such as BZ #5534, and will require changes to all 7003 1.1.1.3.2.1 yamt existing 7004 1.1 jruoho OS interface layers. (Alexey Starikovskiy and Bob Moore) 7005 1.1 jruoho 7006 1.1.1.3.2.1 yamt Fixed a possible memory leak associated with the support for the so- 7007 1.1.1.3.2.1 yamt called 7008 1.1 jruoho "implicit return" ACPI extension. Reported by FreeBSD, BZ #6514. (Fiodor 7009 1.1 jruoho Suietov) 7010 1.1 jruoho 7011 1.1 jruoho Fixed a problem with the Load() operator where a table load from an 7012 1.1.1.3.2.1 yamt operation region could overwrite an internal table buffer by up to 7 7013 1.1.1.3.2.1 yamt bytes 7014 1.1.1.3.2.1 yamt and cause alignment faults on IPF systems. (With assistance from Luming 7015 1.1.1.3.2.1 yamt Yu) 7016 1.1 jruoho 7017 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 7018 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 7019 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 7020 1.1.1.3.2.1 yamt has 7021 1.1 jruoho a much larger code and data size. 7022 1.1 jruoho 7023 1.1 jruoho Previous Release: 7024 1.1 jruoho Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total 7025 1.1 jruoho Debug Version: 160.1K Code, 65.2K Data, 225.3K Total 7026 1.1 jruoho Current Release: 7027 1.1 jruoho Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total 7028 1.1 jruoho Debug Version: 160.5K Code, 65.1K Data, 225.6K Total 7029 1.1 jruoho 7030 1.1 jruoho 7031 1.1 jruoho 7032 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 7033 1.1 jruoho 7034 1.1.1.3.2.1 yamt Disassembler: Implemented support to cross reference the internal 7035 1.1.1.3.2.1 yamt namespace 7036 1.1.1.3.2.1 yamt and automatically generate ASL External() statements for symbols not 7037 1.1.1.3.2.1 yamt defined 7038 1.1 jruoho within the current table being disassembled. This will simplify the 7039 1.1.1.3.2.1 yamt disassembly and recompilation of interdependent tables such as SSDTs 7040 1.1.1.3.2.1 yamt since 7041 1.1 jruoho these statements will no longer have to be added manually. 7042 1.1 jruoho 7043 1.1 jruoho Disassembler: Implemented experimental support to automatically detect 7044 1.1.1.3.2.1 yamt invocations of external control methods and generate appropriate 7045 1.1.1.3.2.1 yamt External() 7046 1.1.1.3.2.1 yamt statements. This is problematic because the AML cannot be correctly 7047 1.1.1.3.2.1 yamt parsed 7048 1.1.1.3.2.1 yamt until the number of arguments for each control method is known. 7049 1.1.1.3.2.1 yamt Currently, 7050 1.1 jruoho standalone method invocations and invocations as the source operand of a 7051 1.1 jruoho Store() statement are supported. 7052 1.1 jruoho 7053 1.1 jruoho Disassembler: Implemented support for the ASL pseudo-operators LNotEqual, 7054 1.1 jruoho LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()), 7055 1.1 jruoho LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code 7056 1.1 jruoho more readable and likely closer to the original ASL source. 7057 1.1 jruoho 7058 1.1 jruoho ---------------------------------------- 7059 1.1 jruoho 21 April 2006. Summary of changes for version 20060421: 7060 1.1 jruoho 7061 1.1 jruoho 1) ACPI CA Core Subsystem: 7062 1.1 jruoho 7063 1.1 jruoho Removed a device initialization optimization introduced in 20051216 where 7064 1.1 jruoho the _STA method was not run unless an _INI was also present for the same 7065 1.1.1.3.2.1 yamt device. This optimization could cause problems because it could allow 7066 1.1.1.3.2.1 yamt _INI 7067 1.1 jruoho methods to be run within a not-present device subtree. (If a not-present 7068 1.1.1.3.2.1 yamt device had no _INI, _STA would not be run, the not-present status would 7069 1.1.1.3.2.1 yamt not 7070 1.1 jruoho be discovered, and the children of the device would be incorrectly 7071 1.1 jruoho traversed.) 7072 1.1 jruoho 7073 1.1 jruoho Implemented a new _STA optimization where namespace subtrees that do not 7074 1.1 jruoho contain _INI are identified and ignored during device initialization. 7075 1.1 jruoho Selectively running _STA can significantly improve boot time on large 7076 1.1 jruoho machines (with assistance from Len Brown.) 7077 1.1 jruoho 7078 1.1 jruoho Implemented support for the device initialization case where the returned 7079 1.1.1.3.2.1 yamt _STA flags indicate a device not-present but functioning. In this case, 7080 1.1.1.3.2.1 yamt _INI 7081 1.1 jruoho is not run, but the device children are examined for presence, as per the 7082 1.1 jruoho ACPI specification. 7083 1.1 jruoho 7084 1.1 jruoho Implemented an additional change to the IndexField support in order to 7085 1.1 jruoho conform to MS behavior. The value written to the Index Register is not 7086 1.1 jruoho simply a byte offset, it is a byte offset in units of the access width of 7087 1.1 jruoho the parent Index Field. (Fiodor Suietov) 7088 1.1 jruoho 7089 1.1 jruoho Defined and deployed a new OSL interface, AcpiOsValidateAddress. This 7090 1.1 jruoho interface is called during the creation of all AML operation regions, and 7091 1.1 jruoho allows the host OS to exert control over what addresses it will allow the 7092 1.1 jruoho AML code to access. Operation Regions whose addresses are disallowed will 7093 1.1.1.3.2.1 yamt cause a runtime exception when they are actually accessed (will not 7094 1.1.1.3.2.1 yamt affect 7095 1.1 jruoho or abort table loading.) See oswinxf or osunixxf for an example 7096 1.1 jruoho implementation. 7097 1.1 jruoho 7098 1.1 jruoho Defined and deployed a new OSL interface, AcpiOsValidateInterface. This 7099 1.1 jruoho interface allows the host OS to match the various "optional" 7100 1.1 jruoho interface/behavior strings for the _OSI predefined control method as 7101 1.1 jruoho appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf 7102 1.1 jruoho for an example implementation. 7103 1.1 jruoho 7104 1.1.1.3.2.1 yamt Restructured and corrected various problems in the exception handling 7105 1.1.1.3.2.1 yamt code 7106 1.1 jruoho paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod 7107 1.1 jruoho (with assistance from Takayoshi Kochi.) 7108 1.1 jruoho 7109 1.1.1.3.2.1 yamt Modified the Linux source converter to ignore quoted string literals 7110 1.1.1.3.2.1 yamt while 7111 1.1.1.3.2.1 yamt converting identifiers from mixed to lower case. This will correct 7112 1.1.1.3.2.1 yamt problems 7113 1.1 jruoho with the disassembler and other areas where such strings must not be 7114 1.1 jruoho modified. 7115 1.1 jruoho 7116 1.1 jruoho The ACPI_FUNCTION_* macros no longer require quotes around the function 7117 1.1.1.3.2.1 yamt name. This allows the Linux source converter to convert the names, now 7118 1.1.1.3.2.1 yamt that 7119 1.1 jruoho the converter ignores quoted strings. 7120 1.1 jruoho 7121 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 7122 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 7123 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 7124 1.1.1.3.2.1 yamt has 7125 1.1 jruoho a much larger code and data size. 7126 1.1 jruoho 7127 1.1 jruoho Previous Release: 7128 1.1 jruoho 7129 1.1 jruoho Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 7130 1.1 jruoho Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 7131 1.1 jruoho Current Release: 7132 1.1 jruoho Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total 7133 1.1 jruoho Debug Version: 160.1K Code, 65.2K Data, 225.3K Total 7134 1.1 jruoho 7135 1.1 jruoho 7136 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 7137 1.1 jruoho 7138 1.1.1.3.2.1 yamt Implemented 3 new warnings for iASL, and implemented multiple warning 7139 1.1.1.3.2.1 yamt levels 7140 1.1 jruoho (w2 flag). 7141 1.1 jruoho 7142 1.1.1.3.2.1 yamt 1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is 7143 1.1.1.3.2.1 yamt not 7144 1.1 jruoho WAIT_FOREVER (0xFFFF) and the code does not examine the return value to 7145 1.1 jruoho check for the possible timeout, a warning is issued. 7146 1.1 jruoho 7147 1.1.1.3.2.1 yamt 2) Useless operators: If an ASL operator does not specify an optional 7148 1.1.1.3.2.1 yamt target 7149 1.1 jruoho operand and it also does not use the function return value from the 7150 1.1.1.3.2.1 yamt operator, a warning is issued since the operator effectively does 7151 1.1.1.3.2.1 yamt nothing. 7152 1.1 jruoho 7153 1.1 jruoho 3) Unreferenced objects: If a namespace object is created, but never 7154 1.1.1.3.2.1 yamt referenced, a warning is issued. This is a warning level 2 since there 7155 1.1.1.3.2.1 yamt are 7156 1.1.1.3.2.1 yamt cases where this is ok, such as when a secondary table is loaded that 7157 1.1.1.3.2.1 yamt uses 7158 1.1.1.3.2.1 yamt the unreferenced objects. Even so, care is taken to only flag objects 7159 1.1.1.3.2.1 yamt that 7160 1.1 jruoho don't look like they will ever be used. For example, the reserved methods 7161 1.1 jruoho (starting with an underscore) are usually not referenced because it is 7162 1.1 jruoho expected that the OS will invoke them. 7163 1.1 jruoho 7164 1.1 jruoho ---------------------------------------- 7165 1.1 jruoho 31 March 2006. Summary of changes for version 20060331: 7166 1.1 jruoho 7167 1.1 jruoho 1) ACPI CA Core Subsystem: 7168 1.1 jruoho 7169 1.1 jruoho Implemented header file support for the following additional ACPI tables: 7170 1.1.1.3.2.1 yamt ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this 7171 1.1.1.3.2.1 yamt support, 7172 1.1.1.3.2.1 yamt all current and known ACPI tables are now defined in the ACPICA headers 7173 1.1.1.3.2.1 yamt and 7174 1.1 jruoho are available for use by device drivers and other software. 7175 1.1 jruoho 7176 1.1 jruoho Implemented support to allow tables that contain ACPI names with invalid 7177 1.1 jruoho characters to be loaded. Previously, this would cause the table load to 7178 1.1 jruoho fail, but since there are several known cases of such tables on existing 7179 1.1.1.3.2.1 yamt machines, this change was made to enable ACPI support for them. Also, 7180 1.1.1.3.2.1 yamt this 7181 1.1 jruoho matches the behavior of the Microsoft ACPI implementation. 7182 1.1 jruoho 7183 1.1.1.3.2.1 yamt Fixed a couple regressions introduced during the memory optimization in 7184 1.1.1.3.2.1 yamt the 7185 1.1 jruoho 20060317 release. The namespace node definition required additional 7186 1.1.1.3.2.1 yamt reorganization and an internal datatype that had been changed to 8-bit 7187 1.1.1.3.2.1 yamt was 7188 1.1 jruoho restored to 32-bit. (Valery Podrezov) 7189 1.1 jruoho 7190 1.1 jruoho Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState 7191 1.1 jruoho could be passed through to AcpiOsReleaseObject which is unexpected. Such 7192 1.1 jruoho null pointers are now trapped and ignored, matching the behavior of the 7193 1.1 jruoho previous implementation before the deployment of AcpiOsReleaseObject. 7194 1.1 jruoho (Valery Podrezov, Fiodor Suietov) 7195 1.1 jruoho 7196 1.1.1.3.2.1 yamt Fixed a memory mapping leak during the deletion of a SystemMemory 7197 1.1.1.3.2.1 yamt operation 7198 1.1 jruoho region where a cached memory mapping was not deleted. This became a 7199 1.1.1.3.2.1 yamt noticeable problem for operation regions that are defined within 7200 1.1.1.3.2.1 yamt frequently 7201 1.1 jruoho used control methods. (Dana Meyers) 7202 1.1 jruoho 7203 1.1 jruoho Reorganized the ACPI table header files into two main files: one for the 7204 1.1.1.3.2.1 yamt ACPI tables consumed by the ACPICA core, and another for the 7205 1.1.1.3.2.1 yamt miscellaneous 7206 1.1.1.3.2.1 yamt ACPI tables that are consumed by the drivers and other software. The 7207 1.1.1.3.2.1 yamt various 7208 1.1 jruoho FADT definitions were merged into one common section and three different 7209 1.1 jruoho tables (ACPI 1.0, 1.0+, and 2.0) 7210 1.1 jruoho 7211 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 7212 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 7213 1.1.1.3.2.1 yamt debug version of the code includes the debug output trace mechanism and 7214 1.1.1.3.2.1 yamt has 7215 1.1 jruoho a much larger code and data size. 7216 1.1 jruoho 7217 1.1 jruoho Previous Release: 7218 1.1 jruoho Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 7219 1.1 jruoho Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 7220 1.1 jruoho Current Release: 7221 1.1 jruoho Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 7222 1.1 jruoho Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 7223 1.1 jruoho 7224 1.1 jruoho 7225 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 7226 1.1 jruoho 7227 1.1 jruoho Disassembler: Implemented support to decode and format all non-AML ACPI 7228 1.1 jruoho tables (tables other than DSDTs and SSDTs.) This includes the new tables 7229 1.1.1.3.2.1 yamt added to the ACPICA headers, therefore all current and known ACPI tables 7230 1.1.1.3.2.1 yamt are 7231 1.1 jruoho supported. 7232 1.1 jruoho 7233 1.1 jruoho Disassembler: The change to allow ACPI names with invalid characters also 7234 1.1.1.3.2.1 yamt enables the disassembly of such tables. Invalid characters within names 7235 1.1.1.3.2.1 yamt are 7236 1.1 jruoho changed to '*' to make the name printable; the iASL compiler will still 7237 1.1 jruoho generate an error for such names, however, since this is an invalid ACPI 7238 1.1 jruoho character. 7239 1.1 jruoho 7240 1.1.1.3.2.1 yamt Implemented an option for AcpiXtract (-a) to extract all tables found in 7241 1.1.1.3.2.1 yamt the 7242 1.1 jruoho input file. The default invocation extracts only the DSDTs and SSDTs. 7243 1.1 jruoho 7244 1.1 jruoho Fixed a couple of gcc generation issues for iASL and AcpiExec and added a 7245 1.1 jruoho makefile for the AcpiXtract utility. 7246 1.1 jruoho 7247 1.1 jruoho ---------------------------------------- 7248 1.1 jruoho 17 March 2006. Summary of changes for version 20060317: 7249 1.1 jruoho 7250 1.1 jruoho 1) ACPI CA Core Subsystem: 7251 1.1 jruoho 7252 1.1 jruoho Implemented the use of a cache object for all internal namespace nodes. 7253 1.1 jruoho Since there are about 1000 static nodes in a typical system, this will 7254 1.1.1.3.2.1 yamt decrease memory use for cache implementations that minimize per- 7255 1.1.1.3.2.1 yamt allocation 7256 1.1 jruoho overhead (such as a slab allocator.) 7257 1.1 jruoho 7258 1.1.1.3.2.1 yamt Removed the reference count mechanism for internal namespace nodes, since 7259 1.1.1.3.2.1 yamt it 7260 1.1 jruoho was deemed unnecessary. This reduces the size of each namespace node by 7261 1.1.1.3.2.1 yamt about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit 7262 1.1.1.3.2.1 yamt case, 7263 1.1 jruoho and 32 bytes for the 64-bit case. 7264 1.1 jruoho 7265 1.1.1.3.2.1 yamt Optimized several internal data structures to reduce object size on 64- 7266 1.1.1.3.2.1 yamt bit 7267 1.1 jruoho platforms by packing data within the 64-bit alignment. This includes the 7268 1.1 jruoho frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static 7269 1.1 jruoho instances corresponding to the namespace objects. 7270 1.1 jruoho 7271 1.1.1.3.2.1 yamt Added two new strings for the predefined _OSI method: "Windows 2001.1 7272 1.1.1.3.2.1 yamt SP1" 7273 1.1 jruoho and "Windows 2006". 7274 1.1 jruoho 7275 1.1 jruoho Split the allocation tracking mechanism out to a separate file, from 7276 1.1 jruoho utalloc.c to uttrack.c. This mechanism appears to be only useful for 7277 1.1 jruoho application-level code. Kernels may wish to not include uttrack.c in 7278 1.1 jruoho distributions. 7279 1.1 jruoho 7280 1.1.1.3.2.1 yamt Removed all remnants of the obsolete ACPI_REPORT_* macros and the 7281 1.1.1.3.2.1 yamt associated 7282 1.1 jruoho code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING 7283 1.1 jruoho macros.) 7284 1.1 jruoho 7285 1.1.1.3.2.1 yamt Code and Data Size: These are the sizes for the acpica.lib produced by 7286 1.1.1.3.2.1 yamt the 7287 1.1.1.3.2.1 yamt Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any 7288 1.1.1.3.2.1 yamt ACPI 7289 1.1.1.3.2.1 yamt driver or OSPM code. The debug version of the code includes the debug 7290 1.1.1.3.2.1 yamt output 7291 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 7292 1.1 jruoho values will vary depending on the efficiency of the compiler and the 7293 1.1 jruoho compiler options used during generation. 7294 1.1 jruoho 7295 1.1 jruoho Previous Release: 7296 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 7297 1.1 jruoho Debug Version: 161.6K Code, 65.7K Data, 227.3K Total 7298 1.1 jruoho Current Release: 7299 1.1 jruoho Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 7300 1.1 jruoho Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 7301 1.1 jruoho 7302 1.1 jruoho 7303 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 7304 1.1 jruoho 7305 1.1.1.3.2.1 yamt Implemented an ANSI C version of the acpixtract utility. This version 7306 1.1.1.3.2.1 yamt will 7307 1.1 jruoho automatically extract the DSDT and all SSDTs from the input acpidump text 7308 1.1 jruoho file and dump the binary output to separate files. It can also display a 7309 1.1 jruoho summary of the input file including the headers for each table found and 7310 1.1 jruoho will extract any single ACPI table, with any signature. (See 7311 1.1 jruoho source/tools/acpixtract) 7312 1.1 jruoho 7313 1.1 jruoho ---------------------------------------- 7314 1.1 jruoho 10 March 2006. Summary of changes for version 20060310: 7315 1.1 jruoho 7316 1.1 jruoho 1) ACPI CA Core Subsystem: 7317 1.1 jruoho 7318 1.1 jruoho Tagged all external interfaces to the subsystem with the new 7319 1.1.1.3.2.1 yamt ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to 7320 1.1.1.3.2.1 yamt assist 7321 1.1 jruoho kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL 7322 1.1 jruoho macro. The default definition is NULL. 7323 1.1 jruoho 7324 1.1.1.3.2.1 yamt Added the ACPI_THREAD_ID type for the return value from 7325 1.1.1.3.2.1 yamt AcpiOsGetThreadId. 7326 1.1 jruoho This allows the host to define this as necessary to simplify kernel 7327 1.1 jruoho integration. The default definition is ACPI_NATIVE_UINT. 7328 1.1 jruoho 7329 1.1.1.3.2.1 yamt Fixed two interpreter problems related to error processing, the deletion 7330 1.1.1.3.2.1 yamt of 7331 1.1 jruoho objects, and placing invalid pointers onto the internal operator result 7332 1.1 jruoho stack. BZ 6028, 6151 (Valery Podrezov) 7333 1.1 jruoho 7334 1.1.1.3.2.1 yamt Increased the reference count threshold where a warning is emitted for 7335 1.1.1.3.2.1 yamt large 7336 1.1.1.3.2.1 yamt reference counts in order to eliminate unnecessary warnings on systems 7337 1.1.1.3.2.1 yamt with 7338 1.1 jruoho large namespaces (especially 64-bit.) Increased the value from 0x400 to 7339 1.1 jruoho 0x800. 7340 1.1 jruoho 7341 1.1.1.3.2.1 yamt Due to universal disagreement as to the meaning of the 'c' in the 7342 1.1.1.3.2.1 yamt calloc() 7343 1.1 jruoho function, the ACPI_MEM_CALLOCATE macro has been renamed to 7344 1.1 jruoho ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. 7345 1.1 jruoho ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and 7346 1.1 jruoho ACPI_FREE. 7347 1.1 jruoho 7348 1.1.1.3.2.1 yamt Code and Data Size: These are the sizes for the acpica.lib produced by 7349 1.1.1.3.2.1 yamt the 7350 1.1.1.3.2.1 yamt Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any 7351 1.1.1.3.2.1 yamt ACPI 7352 1.1.1.3.2.1 yamt driver or OSPM code. The debug version of the code includes the debug 7353 1.1.1.3.2.1 yamt output 7354 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 7355 1.1 jruoho values will vary depending on the efficiency of the compiler and the 7356 1.1 jruoho compiler options used during generation. 7357 1.1 jruoho 7358 1.1 jruoho Previous Release: 7359 1.1 jruoho Non-Debug Version: 81.0K Code, 17.8K Data, 98.8K Total 7360 1.1 jruoho Debug Version: 161.4K Code, 65.7K Data, 227.1K Total 7361 1.1 jruoho Current Release: 7362 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 7363 1.1 jruoho Debug Version: 161.6K Code, 65.7K Data, 227.3K Total 7364 1.1 jruoho 7365 1.1 jruoho 7366 1.1 jruoho 2) iASL Compiler/Disassembler: 7367 1.1 jruoho 7368 1.1 jruoho Disassembler: implemented support for symbolic resource descriptor 7369 1.1.1.3.2.1 yamt references. If a CreateXxxxField operator references a fixed offset 7370 1.1.1.3.2.1 yamt within 7371 1.1.1.3.2.1 yamt a 7372 1.1.1.3.2.1 yamt resource descriptor, a name is assigned to the descriptor and the offset 7373 1.1.1.3.2.1 yamt is 7374 1.1 jruoho translated to the appropriate resource tag and pathname. The addition of 7375 1.1 jruoho this support brings the disassembled code very close to the original ASL 7376 1.1.1.3.2.1 yamt source code and helps eliminate run-time errors when the disassembled 7377 1.1.1.3.2.1 yamt code 7378 1.1 jruoho is modified (and recompiled) in such a way as to invalidate the original 7379 1.1 jruoho fixed offsets. 7380 1.1 jruoho 7381 1.1.1.3.2.1 yamt Implemented support for a Descriptor Name as the last parameter to the 7382 1.1.1.3.2.1 yamt ASL 7383 1.1 jruoho Register() macro. This parameter was inadvertently left out of the ACPI 7384 1.1 jruoho specification, and will be added for ACPI 3.0b. 7385 1.1 jruoho 7386 1.1 jruoho Fixed a problem where the use of the "_OSI" string (versus the full path 7387 1.1 jruoho "\_OSI") caused an internal compiler error. ("No back ptr to op") 7388 1.1 jruoho 7389 1.1.1.3.2.1 yamt Fixed a problem with the error message that occurs when an invalid string 7390 1.1.1.3.2.1 yamt is 7391 1.1.1.3.2.1 yamt used for a _HID object (such as one with an embedded asterisk: 7392 1.1.1.3.2.1 yamt "*PNP010A".) 7393 1.1 jruoho The correct message is now displayed. 7394 1.1 jruoho 7395 1.1 jruoho ---------------------------------------- 7396 1.1 jruoho 17 February 2006. Summary of changes for version 20060217: 7397 1.1 jruoho 7398 1.1 jruoho 1) ACPI CA Core Subsystem: 7399 1.1 jruoho 7400 1.1.1.3.2.1 yamt Implemented a change to the IndexField support to match the behavior of 7401 1.1.1.3.2.1 yamt the 7402 1.1.1.3.2.1 yamt Microsoft AML interpreter. The value written to the Index register is now 7403 1.1.1.3.2.1 yamt a 7404 1.1.1.3.2.1 yamt byte offset, no longer an index based upon the width of the Data 7405 1.1.1.3.2.1 yamt register. 7406 1.1 jruoho This should fix IndexField problems seen on some machines where the Data 7407 1.1 jruoho register is not exactly one byte wide. The ACPI specification will be 7408 1.1 jruoho clarified on this point. 7409 1.1 jruoho 7410 1.1 jruoho Fixed a problem where several resource descriptor types could overrun the 7411 1.1 jruoho internal descriptor buffer due to size miscalculation: VendorShort, 7412 1.1 jruoho VendorLong, and Interrupt. This was noticed on IA64 machines, but could 7413 1.1 jruoho affect all platforms. 7414 1.1 jruoho 7415 1.1.1.3.2.1 yamt Fixed a problem where individual resource descriptors were misaligned 7416 1.1.1.3.2.1 yamt within 7417 1.1 jruoho the internal buffer, causing alignment faults on IA64 platforms. 7418 1.1 jruoho 7419 1.1.1.3.2.1 yamt Code and Data Size: These are the sizes for the acpica.lib produced by 7420 1.1.1.3.2.1 yamt the 7421 1.1.1.3.2.1 yamt Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any 7422 1.1.1.3.2.1 yamt ACPI 7423 1.1.1.3.2.1 yamt driver or OSPM code. The debug version of the code includes the debug 7424 1.1.1.3.2.1 yamt output 7425 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 7426 1.1 jruoho values will vary depending on the efficiency of the compiler and the 7427 1.1 jruoho compiler options used during generation. 7428 1.1 jruoho 7429 1.1 jruoho Previous Release: 7430 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 7431 1.1 jruoho Debug Version: 161.3K Code, 65.6K Data, 226.9K Total 7432 1.1 jruoho Current Release: 7433 1.1 jruoho Non-Debug Version: 81.0K Code, 17.8K Data, 98.8K Total 7434 1.1 jruoho Debug Version: 161.4K Code, 65.7K Data, 227.1K Total 7435 1.1 jruoho 7436 1.1 jruoho 7437 1.1 jruoho 2) iASL Compiler/Disassembler: 7438 1.1 jruoho 7439 1.1 jruoho Implemented support for new reserved names: _WDG and _WED are Microsoft 7440 1.1 jruoho extensions for Windows Instrumentation Management, _TDL is a new ACPI- 7441 1.1 jruoho defined method (Throttling Depth Limit.) 7442 1.1 jruoho 7443 1.1 jruoho Fixed a problem where a zero-length VendorShort or VendorLong resource 7444 1.1 jruoho descriptor was incorrectly emitted as a descriptor of length one. 7445 1.1 jruoho 7446 1.1 jruoho ---------------------------------------- 7447 1.1 jruoho 10 February 2006. Summary of changes for version 20060210: 7448 1.1 jruoho 7449 1.1 jruoho 1) ACPI CA Core Subsystem: 7450 1.1 jruoho 7451 1.1 jruoho Removed a couple of extraneous ACPI_ERROR messages that appeared during 7452 1.1 jruoho normal execution. These became apparent after the conversion from 7453 1.1 jruoho ACPI_DEBUG_PRINT. 7454 1.1 jruoho 7455 1.1.1.3.2.1 yamt Fixed a problem where the CreateField operator could hang if the BitIndex 7456 1.1.1.3.2.1 yamt or 7457 1.1 jruoho NumBits parameter referred to a named object. (Valery Podrezov, BZ 5359) 7458 1.1 jruoho 7459 1.1 jruoho Fixed a problem where a DeRefOf operation on a buffer object incorrectly 7460 1.1 jruoho failed with an exception. This also fixes a couple of related RefOf and 7461 1.1 jruoho DeRefOf issues. (Valery Podrezov, BZ 5360/5392/5387) 7462 1.1 jruoho 7463 1.1.1.3.2.1 yamt Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead 7464 1.1.1.3.2.1 yamt of 7465 1.1.1.3.2.1 yamt AE_STRING_LIMIT on an out-of-bounds Index() operation. (Valery Podrezov, 7466 1.1.1.3.2.1 yamt BZ 7467 1.1 jruoho 5480) 7468 1.1 jruoho 7469 1.1.1.3.2.1 yamt Implemented a memory cleanup at the end of the execution of each 7470 1.1.1.3.2.1 yamt iteration 7471 1.1.1.3.2.1 yamt of an AML While() loop, preventing the accumulation of outstanding 7472 1.1.1.3.2.1 yamt objects. 7473 1.1 jruoho (Valery Podrezov, BZ 5427) 7474 1.1 jruoho 7475 1.1.1.3.2.1 yamt Eliminated a chunk of duplicate code in the object resolution code. 7476 1.1.1.3.2.1 yamt (Valery 7477 1.1 jruoho Podrezov, BZ 5336) 7478 1.1 jruoho 7479 1.1 jruoho Fixed several warnings during the 64-bit code generation. 7480 1.1 jruoho 7481 1.1.1.3.2.1 yamt The AcpiSrc source code conversion tool now inserts one line of 7482 1.1.1.3.2.1 yamt whitespace 7483 1.1.1.3.2.1 yamt after an if() statement that is followed immediately by a comment, 7484 1.1.1.3.2.1 yamt improving 7485 1.1 jruoho readability of the Linux code. 7486 1.1 jruoho 7487 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7488 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7489 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7490 1.1.1.3.2.1 yamt These 7491 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7492 1.1.1.3.2.1 yamt the 7493 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7494 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7495 1.1.1.3.2.1 yamt efficiency 7496 1.1 jruoho of the compiler and the compiler options used during generation. 7497 1.1 jruoho 7498 1.1 jruoho Previous Release: 7499 1.1 jruoho Non-Debug Version: 81.0K Code, 17.9K Data, 98.9K Total 7500 1.1 jruoho Debug Version: 161.3K Code, 65.7K Data, 227.0K Total 7501 1.1 jruoho Current Release: 7502 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 7503 1.1 jruoho Debug Version: 161.3K Code, 65.6K Data, 226.9K Total 7504 1.1 jruoho 7505 1.1 jruoho 7506 1.1 jruoho 2) iASL Compiler/Disassembler: 7507 1.1 jruoho 7508 1.1.1.3.2.1 yamt Fixed a problem with the disassembly of a BankField operator with a 7509 1.1.1.3.2.1 yamt complex 7510 1.1 jruoho expression for the BankValue parameter. 7511 1.1 jruoho 7512 1.1 jruoho ---------------------------------------- 7513 1.1 jruoho 27 January 2006. Summary of changes for version 20060127: 7514 1.1 jruoho 7515 1.1 jruoho 1) ACPI CA Core Subsystem: 7516 1.1 jruoho 7517 1.1.1.3.2.1 yamt Implemented support in the Resource Manager to allow unresolved 7518 1.1.1.3.2.1 yamt namestring 7519 1.1.1.3.2.1 yamt references within resource package objects for the _PRT method. This 7520 1.1.1.3.2.1 yamt support 7521 1.1 jruoho is in addition to the previously implemented unresolved reference support 7522 1.1 jruoho within the AML parser. If the interpreter slack mode is enabled, these 7523 1.1.1.3.2.1 yamt unresolved references will be passed through to the caller as a NULL 7524 1.1.1.3.2.1 yamt package 7525 1.1 jruoho entry. 7526 1.1 jruoho 7527 1.1 jruoho Implemented and deployed new macros and functions for error and warning 7528 1.1 jruoho messages across the subsystem. These macros are simpler and generate less 7529 1.1 jruoho code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, 7530 1.1 jruoho ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older 7531 1.1 jruoho macros remain defined to allow ACPI drivers time to migrate to the new 7532 1.1 jruoho macros. 7533 1.1 jruoho 7534 1.1.1.3.2.1 yamt Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of 7535 1.1.1.3.2.1 yamt the 7536 1.1 jruoho Acquire/Release Lock OSL interfaces. 7537 1.1 jruoho 7538 1.1 jruoho Fixed a problem where Alias ASL operators are sometimes not correctly 7539 1.1 jruoho resolved, in both the interpreter and the iASL compiler. 7540 1.1 jruoho 7541 1.1.1.3.2.1 yamt Fixed several problems with the implementation of the 7542 1.1.1.3.2.1 yamt ConcatenateResTemplate 7543 1.1 jruoho ASL operator. As per the ACPI specification, zero length buffers are now 7544 1.1 jruoho treated as a single EndTag. One-length buffers always cause a fatal 7545 1.1.1.3.2.1 yamt exception. Non-zero length buffers that do not end with a full 2-byte 7546 1.1.1.3.2.1 yamt EndTag 7547 1.1 jruoho cause a fatal exception. 7548 1.1 jruoho 7549 1.1 jruoho Fixed a possible structure overwrite in the AcpiGetObjectInfo external 7550 1.1 jruoho interface. (With assistance from Thomas Renninger) 7551 1.1 jruoho 7552 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7553 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7554 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7555 1.1.1.3.2.1 yamt These 7556 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7557 1.1.1.3.2.1 yamt the 7558 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7559 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7560 1.1.1.3.2.1 yamt efficiency 7561 1.1 jruoho of the compiler and the compiler options used during generation. 7562 1.1 jruoho 7563 1.1 jruoho Previous Release: 7564 1.1 jruoho Non-Debug Version: 83.1K Code, 18.4K Data, 101.5K Total 7565 1.1 jruoho Debug Version: 163.2K Code, 66.2K Data, 229.4K Total 7566 1.1 jruoho Current Release: 7567 1.1 jruoho Non-Debug Version: 81.0K Code, 17.9K Data, 98.9K Total 7568 1.1 jruoho Debug Version: 161.3K Code, 65.7K Data, 227.0K Total 7569 1.1 jruoho 7570 1.1 jruoho 7571 1.1 jruoho 2) iASL Compiler/Disassembler: 7572 1.1 jruoho 7573 1.1.1.3.2.1 yamt Fixed an internal error that was generated for any forward references to 7574 1.1.1.3.2.1 yamt ASL 7575 1.1 jruoho Alias objects. 7576 1.1 jruoho 7577 1.1 jruoho ---------------------------------------- 7578 1.1 jruoho 13 January 2006. Summary of changes for version 20060113: 7579 1.1 jruoho 7580 1.1 jruoho 1) ACPI CA Core Subsystem: 7581 1.1 jruoho 7582 1.1 jruoho Added 2006 copyright to all module headers and signons. This affects 7583 1.1 jruoho virtually every file in the ACPICA core subsystem, iASL compiler, and the 7584 1.1 jruoho utilities. 7585 1.1 jruoho 7586 1.1.1.3.2.1 yamt Enhanced the ACPICA error reporting in order to simplify user migration 7587 1.1.1.3.2.1 yamt to 7588 1.1 jruoho the non-debug version of ACPICA. Replaced all instances of the 7589 1.1.1.3.2.1 yamt ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN 7590 1.1.1.3.2.1 yamt debug 7591 1.1 jruoho levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, 7592 1.1.1.3.2.1 yamt respectively. This preserves all error and warning messages in the non- 7593 1.1.1.3.2.1 yamt debug 7594 1.1 jruoho version of the ACPICA code (this has been referred to as the "debug lite" 7595 1.1 jruoho option.) Over 200 cases were converted to create a total of over 380 7596 1.1.1.3.2.1 yamt error/warning messages across the ACPICA code. This increases the code 7597 1.1.1.3.2.1 yamt and 7598 1.1.1.3.2.1 yamt data size of the default non-debug version of the code somewhat (about 7599 1.1.1.3.2.1 yamt 13K), 7600 1.1 jruoho but all error/warning reporting may be disabled if desired (and code 7601 1.1 jruoho eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time 7602 1.1.1.3.2.1 yamt configuration option. The size of the debug version of ACPICA remains 7603 1.1.1.3.2.1 yamt about 7604 1.1 jruoho the same. 7605 1.1 jruoho 7606 1.1 jruoho Fixed a memory leak within the AML Debugger "Set" command. One object was 7607 1.1 jruoho not properly deleted for every successful invocation of the command. 7608 1.1 jruoho 7609 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7610 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7611 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7612 1.1.1.3.2.1 yamt These 7613 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7614 1.1.1.3.2.1 yamt the 7615 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7616 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7617 1.1.1.3.2.1 yamt efficiency 7618 1.1 jruoho of the compiler and the compiler options used during generation. 7619 1.1 jruoho 7620 1.1 jruoho Previous Release: 7621 1.1 jruoho Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total 7622 1.1 jruoho Debug Version: 163.7K Code, 67.5K Data, 231.2K Total 7623 1.1 jruoho Current Release: 7624 1.1 jruoho Non-Debug Version: 83.1K Code, 18.4K Data, 101.5K Total 7625 1.1 jruoho Debug Version: 163.2K Code, 66.2K Data, 229.4K Total 7626 1.1 jruoho 7627 1.1 jruoho 7628 1.1 jruoho 2) iASL Compiler/Disassembler: 7629 1.1 jruoho 7630 1.1 jruoho The compiler now officially supports the ACPI 3.0a specification that was 7631 1.1.1.3.2.1 yamt released on December 30, 2005. (Specification is available at 7632 1.1.1.3.2.1 yamt www.acpi.info) 7633 1.1 jruoho 7634 1.1 jruoho ---------------------------------------- 7635 1.1 jruoho 16 December 2005. Summary of changes for version 20051216: 7636 1.1 jruoho 7637 1.1 jruoho 1) ACPI CA Core Subsystem: 7638 1.1 jruoho 7639 1.1 jruoho Implemented optional support to allow unresolved names within ASL Package 7640 1.1 jruoho objects. A null object is inserted in the package when a named reference 7641 1.1 jruoho cannot be located in the current namespace. Enabled via the interpreter 7642 1.1.1.3.2.1 yamt slack flag, this should eliminate AE_NOT_FOUND exceptions seen on 7643 1.1.1.3.2.1 yamt machines 7644 1.1 jruoho that contain such code. 7645 1.1 jruoho 7646 1.1.1.3.2.1 yamt Implemented an optimization to the initialization sequence that can 7647 1.1.1.3.2.1 yamt improve 7648 1.1.1.3.2.1 yamt boot time. During ACPI device initialization, the _STA method is now run 7649 1.1.1.3.2.1 yamt if 7650 1.1.1.3.2.1 yamt and only if the _INI method exists. The _STA method is used to determine 7651 1.1.1.3.2.1 yamt if 7652 1.1.1.3.2.1 yamt the device is present; An _INI can only be run if _STA returns present, 7653 1.1.1.3.2.1 yamt but 7654 1.1 jruoho it is a waste of time to run the _STA method if the _INI does not exist. 7655 1.1 jruoho (Prototype and assistance from Dong Wei) 7656 1.1 jruoho 7657 1.1.1.3.2.1 yamt Implemented use of the C99 uintptr_t for the pointer casting macros if it 7658 1.1.1.3.2.1 yamt is 7659 1.1.1.3.2.1 yamt available in the current compiler. Otherwise, the default (void *) cast 7660 1.1.1.3.2.1 yamt is 7661 1.1 jruoho used as before. 7662 1.1 jruoho 7663 1.1 jruoho Fixed some possible memory leaks found within the execution path of the 7664 1.1 jruoho Break, Continue, If, and CreateField operators. (Valery Podrezov) 7665 1.1 jruoho 7666 1.1 jruoho Fixed a problem introduced in the 20051202 release where an exception is 7667 1.1 jruoho generated during method execution if a control method attempts to declare 7668 1.1 jruoho another method. 7669 1.1 jruoho 7670 1.1 jruoho Moved resource descriptor string constants that are used by both the AML 7671 1.1 jruoho disassembler and AML debugger to the common utilities directory so that 7672 1.1 jruoho these components are independent. 7673 1.1 jruoho 7674 1.1.1.3.2.1 yamt Implemented support in the AcpiExec utility (-e switch) to globally 7675 1.1.1.3.2.1 yamt ignore 7676 1.1 jruoho exceptions during control method execution (method is not aborted.) 7677 1.1 jruoho 7678 1.1 jruoho Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix 7679 1.1 jruoho generation. 7680 1.1 jruoho 7681 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7682 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7683 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7684 1.1.1.3.2.1 yamt These 7685 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7686 1.1.1.3.2.1 yamt the 7687 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7688 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7689 1.1.1.3.2.1 yamt efficiency 7690 1.1 jruoho of the compiler and the compiler options used during generation. 7691 1.1 jruoho 7692 1.1 jruoho Previous Release: 7693 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 7694 1.1 jruoho Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 7695 1.1 jruoho Current Release: 7696 1.1 jruoho Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total 7697 1.1 jruoho Debug Version: 163.7K Code, 67.5K Data, 231.2K Total 7698 1.1 jruoho 7699 1.1 jruoho 7700 1.1 jruoho 2) iASL Compiler/Disassembler: 7701 1.1 jruoho 7702 1.1.1.3.2.1 yamt Fixed a problem where a CPU stack overflow fault could occur if a 7703 1.1.1.3.2.1 yamt recursive 7704 1.1 jruoho method call was made from within a Return statement. 7705 1.1 jruoho 7706 1.1 jruoho ---------------------------------------- 7707 1.1 jruoho 02 December 2005. Summary of changes for version 20051202: 7708 1.1 jruoho 7709 1.1 jruoho 1) ACPI CA Core Subsystem: 7710 1.1 jruoho 7711 1.1 jruoho Modified the parsing of control methods to no longer create namespace 7712 1.1 jruoho objects during the first pass of the parse. Objects are now created only 7713 1.1.1.3.2.1 yamt during the execute phase, at the moment the namespace creation operator 7714 1.1.1.3.2.1 yamt is 7715 1.1.1.3.2.1 yamt encountered in the AML (Name, OperationRegion, CreateByteField, etc.) 7716 1.1.1.3.2.1 yamt This 7717 1.1 jruoho should eliminate ALREADY_EXISTS exceptions seen on some machines where 7718 1.1.1.3.2.1 yamt reentrant control methods are protected by an AML mutex. The mutex will 7719 1.1.1.3.2.1 yamt now 7720 1.1.1.3.2.1 yamt correctly block multiple threads from attempting to create the same 7721 1.1.1.3.2.1 yamt object 7722 1.1 jruoho more than once. 7723 1.1 jruoho 7724 1.1 jruoho Increased the number of available Owner Ids for namespace object tracking 7725 1.1.1.3.2.1 yamt from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen 7726 1.1.1.3.2.1 yamt on 7727 1.1.1.3.2.1 yamt some machines with a large number of ACPI tables (either static or 7728 1.1.1.3.2.1 yamt dynamic). 7729 1.1 jruoho 7730 1.1.1.3.2.1 yamt Fixed a problem with the AcpiExec utility where a fault could occur when 7731 1.1.1.3.2.1 yamt the 7732 1.1 jruoho -b switch (batch mode) is used. 7733 1.1 jruoho 7734 1.1 jruoho Enhanced the namespace dump routine to output the owner ID for each 7735 1.1 jruoho namespace object. 7736 1.1 jruoho 7737 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7738 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7739 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7740 1.1.1.3.2.1 yamt These 7741 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7742 1.1.1.3.2.1 yamt the 7743 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7744 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7745 1.1.1.3.2.1 yamt efficiency 7746 1.1 jruoho of the compiler and the compiler options used during generation. 7747 1.1 jruoho 7748 1.1 jruoho Previous Release: 7749 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 7750 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 7751 1.1 jruoho Current Release: 7752 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 7753 1.1 jruoho Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 7754 1.1 jruoho 7755 1.1 jruoho 7756 1.1 jruoho 2) iASL Compiler/Disassembler: 7757 1.1 jruoho 7758 1.1.1.3.2.1 yamt Fixed a parse error during compilation of certain Switch/Case constructs. 7759 1.1.1.3.2.1 yamt To 7760 1.1.1.3.2.1 yamt simplify the parse, the grammar now allows for multiple Default 7761 1.1.1.3.2.1 yamt statements 7762 1.1 jruoho and this error is now detected and flagged during the analysis phase. 7763 1.1 jruoho 7764 1.1 jruoho Disassembler: The disassembly now includes the contents of the original 7765 1.1 jruoho table header within a comment at the start of the file. This includes the 7766 1.1 jruoho name and version of the original ASL compiler. 7767 1.1 jruoho 7768 1.1 jruoho ---------------------------------------- 7769 1.1 jruoho 17 November 2005. Summary of changes for version 20051117: 7770 1.1 jruoho 7771 1.1 jruoho 1) ACPI CA Core Subsystem: 7772 1.1 jruoho 7773 1.1 jruoho Fixed a problem in the AML parser where the method thread count could be 7774 1.1.1.3.2.1 yamt decremented below zero if any errors occurred during the method parse 7775 1.1.1.3.2.1 yamt phase. 7776 1.1.1.3.2.1 yamt This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some 7777 1.1.1.3.2.1 yamt machines. 7778 1.1 jruoho This also fixed a related regression with the mechanism that detects and 7779 1.1 jruoho corrects methods that cannot properly handle reentrancy (related to the 7780 1.1 jruoho deployment of the new OwnerId mechanism.) 7781 1.1 jruoho 7782 1.1 jruoho Eliminated the pre-parsing of control methods (to detect errors) during 7783 1.1.1.3.2.1 yamt table load. Related to the problem above, this was causing unwind issues 7784 1.1.1.3.2.1 yamt if 7785 1.1.1.3.2.1 yamt any errors occurred during the parse, and it seemed to be overkill. A 7786 1.1.1.3.2.1 yamt table 7787 1.1 jruoho load should not be aborted if there are problems with any single control 7788 1.1 jruoho method, thus rendering this feature rather pointless. 7789 1.1 jruoho 7790 1.1.1.3.2.1 yamt Fixed a problem with the new table-driven resource manager where an 7791 1.1.1.3.2.1 yamt internal 7792 1.1 jruoho buffer overflow could occur for small resource templates. 7793 1.1 jruoho 7794 1.1.1.3.2.1 yamt Implemented a new external interface, AcpiGetVendorResource. This 7795 1.1.1.3.2.1 yamt interface 7796 1.1.1.3.2.1 yamt will find and return a vendor-defined resource descriptor within a _CRS 7797 1.1.1.3.2.1 yamt or 7798 1.1.1.3.2.1 yamt _PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn 7799 1.1.1.3.2.1 yamt Helgaas. 7800 1.1 jruoho 7801 1.1 jruoho Removed the length limit (200) on string objects as per the upcoming ACPI 7802 1.1.1.3.2.1 yamt 3.0A specification. This affects the following areas of the interpreter: 7803 1.1.1.3.2.1 yamt 1) 7804 1.1.1.3.2.1 yamt any implicit conversion of a Buffer to a String, 2) a String object 7805 1.1.1.3.2.1 yamt result 7806 1.1 jruoho of the ASL Concatentate operator, 3) the String object result of the ASL 7807 1.1 jruoho ToString operator. 7808 1.1 jruoho 7809 1.1.1.3.2.1 yamt Fixed a problem in the Windows OS interface layer (OSL) where a 7810 1.1.1.3.2.1 yamt WAIT_FOREVER 7811 1.1 jruoho on a semaphore object would incorrectly timeout. This allows the 7812 1.1 jruoho multithreading features of the AcpiExec utility to work properly under 7813 1.1 jruoho Windows. 7814 1.1 jruoho 7815 1.1 jruoho Updated the Linux makefiles for the iASL compiler and AcpiExec to include 7816 1.1 jruoho the recently added file named "utresrc.c". 7817 1.1 jruoho 7818 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7819 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7820 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7821 1.1.1.3.2.1 yamt These 7822 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7823 1.1.1.3.2.1 yamt the 7824 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7825 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7826 1.1.1.3.2.1 yamt efficiency 7827 1.1 jruoho of the compiler and the compiler options used during generation. 7828 1.1 jruoho 7829 1.1 jruoho Previous Release: 7830 1.1 jruoho Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 7831 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 7832 1.1 jruoho Current Release: 7833 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 7834 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 7835 1.1 jruoho 7836 1.1 jruoho 7837 1.1 jruoho 2) iASL Compiler/Disassembler: 7838 1.1 jruoho 7839 1.1 jruoho Removed the limit (200) on string objects as per the upcoming ACPI 3.0A 7840 1.1.1.3.2.1 yamt specification. For the iASL compiler, this means that string literals 7841 1.1.1.3.2.1 yamt within 7842 1.1 jruoho the source ASL can be of any length. 7843 1.1 jruoho 7844 1.1 jruoho Enhanced the listing output to dump the AML code for resource descriptors 7845 1.1.1.3.2.1 yamt immediately after the ASL code for each descriptor, instead of in a block 7846 1.1.1.3.2.1 yamt at 7847 1.1 jruoho the end of the entire resource template. 7848 1.1 jruoho 7849 1.1 jruoho Enhanced the compiler debug output to dump the entire original parse tree 7850 1.1.1.3.2.1 yamt constructed during the parse phase, before any transforms are applied to 7851 1.1.1.3.2.1 yamt the 7852 1.1 jruoho tree. The transformed tree is dumped also. 7853 1.1 jruoho 7854 1.1 jruoho ---------------------------------------- 7855 1.1 jruoho 02 November 2005. Summary of changes for version 20051102: 7856 1.1 jruoho 7857 1.1 jruoho 1) ACPI CA Core Subsystem: 7858 1.1 jruoho 7859 1.1.1.3.2.1 yamt Modified the subsystem initialization sequence to improve GPE support. 7860 1.1.1.3.2.1 yamt The 7861 1.1.1.3.2.1 yamt GPE initialization has been split into two parts in order to defer 7862 1.1.1.3.2.1 yamt execution 7863 1.1.1.3.2.1 yamt of the _PRW methods (Power Resources for Wake) until after the hardware 7864 1.1.1.3.2.1 yamt is 7865 1.1 jruoho fully initialized and the SCI handler is installed. This allows the _PRW 7866 1.1.1.3.2.1 yamt methods to access fields protected by the Global Lock. This will fix 7867 1.1.1.3.2.1 yamt systems 7868 1.1 jruoho where a NO_GLOBAL_LOCK exception has been seen during initialization. 7869 1.1 jruoho 7870 1.1.1.3.2.1 yamt Converted the ACPI internal object disassemble and display code within 7871 1.1.1.3.2.1 yamt the 7872 1.1 jruoho AML debugger to fully table-driven operation, reducing code size and 7873 1.1 jruoho increasing maintainability. 7874 1.1 jruoho 7875 1.1.1.3.2.1 yamt Fixed a regression with the ConcatenateResTemplate() ASL operator 7876 1.1.1.3.2.1 yamt introduced 7877 1.1 jruoho in the 20051021 release. 7878 1.1 jruoho 7879 1.1 jruoho Implemented support for "local" internal ACPI object types within the 7880 1.1 jruoho debugger "Object" command and the AcpiWalkNamespace external interfaces. 7881 1.1.1.3.2.1 yamt These local types include RegionFields, BankFields, IndexFields, Alias, 7882 1.1.1.3.2.1 yamt and 7883 1.1 jruoho reference objects. 7884 1.1 jruoho 7885 1.1.1.3.2.1 yamt Moved common AML resource handling code into a new file, "utresrc.c". 7886 1.1.1.3.2.1 yamt This 7887 1.1 jruoho code is shared by both the Resource Manager and the AML Debugger. 7888 1.1 jruoho 7889 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7890 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7891 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7892 1.1.1.3.2.1 yamt These 7893 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7894 1.1.1.3.2.1 yamt the 7895 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7896 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7897 1.1.1.3.2.1 yamt efficiency 7898 1.1 jruoho of the compiler and the compiler options used during generation. 7899 1.1 jruoho 7900 1.1 jruoho Previous Release: 7901 1.1 jruoho Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 7902 1.1 jruoho Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 7903 1.1 jruoho Current Release: 7904 1.1 jruoho Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 7905 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 7906 1.1 jruoho 7907 1.1 jruoho 7908 1.1 jruoho 2) iASL Compiler/Disassembler: 7909 1.1 jruoho 7910 1.1.1.3.2.1 yamt Fixed a problem with very large initializer lists (more than 4000 7911 1.1.1.3.2.1 yamt elements) 7912 1.1 jruoho for both Buffer and Package objects where the parse stack could overflow. 7913 1.1 jruoho 7914 1.1.1.3.2.1 yamt Enhanced the pre-compile source code scan for non-ASCII characters to 7915 1.1.1.3.2.1 yamt ignore 7916 1.1.1.3.2.1 yamt characters within comment fields. The scan is now always performed and is 7917 1.1.1.3.2.1 yamt no 7918 1.1 jruoho longer optional, detecting invalid characters within a source file 7919 1.1 jruoho immediately rather than during the parse phase or later. 7920 1.1 jruoho 7921 1.1.1.3.2.1 yamt Enhanced the ASL grammar definition to force early reductions on all 7922 1.1.1.3.2.1 yamt list- 7923 1.1 jruoho style grammar elements so that the overall parse stack usage is greatly 7924 1.1.1.3.2.1 yamt reduced. This should improve performance and reduce the possibility of 7925 1.1.1.3.2.1 yamt parse 7926 1.1 jruoho stack overflow. 7927 1.1 jruoho 7928 1.1.1.3.2.1 yamt Eliminated all reduce/reduce conflicts in the iASL parser generation. 7929 1.1.1.3.2.1 yamt Also, 7930 1.1 jruoho with the addition of a %expected statement, the compiler generates from 7931 1.1 jruoho source with no warnings. 7932 1.1 jruoho 7933 1.1 jruoho Fixed a possible segment fault in the disassembler if the input filename 7934 1.1 jruoho does not contain a "dot" extension (Thomas Renninger). 7935 1.1 jruoho 7936 1.1 jruoho ---------------------------------------- 7937 1.1 jruoho 21 October 2005. Summary of changes for version 20051021: 7938 1.1 jruoho 7939 1.1 jruoho 1) ACPI CA Core Subsystem: 7940 1.1 jruoho 7941 1.1 jruoho Implemented support for the EM64T and other x86-64 processors. This 7942 1.1 jruoho essentially entails recognizing that these processors support non-aligned 7943 1.1 jruoho memory transfers. Previously, all 64-bit processors were assumed to lack 7944 1.1 jruoho hardware support for non-aligned transfers. 7945 1.1 jruoho 7946 1.1 jruoho Completed conversion of the Resource Manager to nearly full table-driven 7947 1.1 jruoho operation. Specifically, the resource conversion code (convert AML to 7948 1.1 jruoho internal format and the reverse) and the debug code to dump internal 7949 1.1.1.3.2.1 yamt resource descriptors are fully table-driven, reducing code and data size 7950 1.1.1.3.2.1 yamt and 7951 1.1 jruoho improving maintainability. 7952 1.1 jruoho 7953 1.1.1.3.2.1 yamt The OSL interfaces for Acquire and Release Lock now use a 64-bit flag 7954 1.1.1.3.2.1 yamt word 7955 1.1.1.3.2.1 yamt on 64-bit processors instead of a fixed 32-bit word. (With assistance 7956 1.1.1.3.2.1 yamt from 7957 1.1 jruoho Alexey Starikovskiy) 7958 1.1 jruoho 7959 1.1 jruoho Implemented support within the resource conversion code for the Type- 7960 1.1 jruoho Specific byte within the various ACPI 3.0 *WordSpace macros. 7961 1.1 jruoho 7962 1.1.1.3.2.1 yamt Fixed some issues within the resource conversion code for the type- 7963 1.1.1.3.2.1 yamt specific 7964 1.1 jruoho flags for both Memory and I/O address resource descriptors. For Memory, 7965 1.1 jruoho implemented support for the MTP and TTP flags. For I/O, split the TRS and 7966 1.1 jruoho TTP flags into two separate fields. 7967 1.1 jruoho 7968 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 7969 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 7970 1.1.1.3.2.1 yamt acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. 7971 1.1.1.3.2.1 yamt These 7972 1.1.1.3.2.1 yamt values do not include any ACPI driver or OSPM code. The debug version of 7973 1.1.1.3.2.1 yamt the 7974 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 7975 1.1.1.3.2.1 yamt and data size. Note that these values will vary depending on the 7976 1.1.1.3.2.1 yamt efficiency 7977 1.1 jruoho of the compiler and the compiler options used during generation. 7978 1.1 jruoho 7979 1.1 jruoho Previous Release: 7980 1.1 jruoho Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total 7981 1.1 jruoho Debug Version: 168.0K Code, 68.3K Data, 236.3K Total 7982 1.1 jruoho Current Release: 7983 1.1 jruoho Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 7984 1.1 jruoho Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 7985 1.1 jruoho 7986 1.1 jruoho 7987 1.1 jruoho 7988 1.1 jruoho 2) iASL Compiler/Disassembler: 7989 1.1 jruoho 7990 1.1.1.3.2.1 yamt Relaxed a compiler restriction that disallowed a ResourceIndex byte if 7991 1.1.1.3.2.1 yamt the 7992 1.1 jruoho corresponding ResourceSource string was not also present in a resource 7993 1.1 jruoho descriptor declaration. This restriction caused problems with existing 7994 1.1.1.3.2.1 yamt AML/ASL code that includes the Index byte without the string. When such 7995 1.1.1.3.2.1 yamt AML 7996 1.1 jruoho was disassembled, it could not be compiled without modification. Further, 7997 1.1.1.3.2.1 yamt the modified code created a resource template with a different size than 7998 1.1.1.3.2.1 yamt the 7999 1.1.1.3.2.1 yamt original, breaking code that used fixed offsets into the resource 8000 1.1.1.3.2.1 yamt template 8001 1.1 jruoho buffer. 8002 1.1 jruoho 8003 1.1.1.3.2.1 yamt Removed a recent feature of the disassembler to ignore a lone 8004 1.1.1.3.2.1 yamt ResourceIndex 8005 1.1 jruoho byte. This byte is now emitted if present so that the exact AML can be 8006 1.1 jruoho reproduced when the disassembled code is recompiled. 8007 1.1 jruoho 8008 1.1 jruoho Improved comments and text alignment for the resource descriptor code 8009 1.1 jruoho emitted by the disassembler. 8010 1.1 jruoho 8011 1.1.1.3.2.1 yamt Implemented disassembler support for the ACPI 3.0 AccessSize field within 8012 1.1.1.3.2.1 yamt a 8013 1.1 jruoho Register() resource descriptor. 8014 1.1 jruoho 8015 1.1 jruoho ---------------------------------------- 8016 1.1 jruoho 30 September 2005. Summary of changes for version 20050930: 8017 1.1 jruoho 8018 1.1 jruoho 1) ACPI CA Core Subsystem: 8019 1.1 jruoho 8020 1.1 jruoho Completed a major overhaul of the Resource Manager code - specifically, 8021 1.1.1.3.2.1 yamt optimizations in the area of the AML/internal resource conversion code. 8022 1.1.1.3.2.1 yamt The 8023 1.1.1.3.2.1 yamt code has been optimized to simplify and eliminate duplicated code, CPU 8024 1.1.1.3.2.1 yamt stack 8025 1.1 jruoho use has been decreased by optimizing function parameters and local 8026 1.1.1.3.2.1 yamt variables, and naming conventions across the manager have been 8027 1.1.1.3.2.1 yamt standardized 8028 1.1 jruoho for clarity and ease of maintenance (this includes function, parameter, 8029 1.1 jruoho variable, and struct/typedef names.) The update may force changes in some 8030 1.1 jruoho driver code, depending on how resources are handled by the host OS. 8031 1.1 jruoho 8032 1.1 jruoho All Resource Manager dispatch and information tables have been moved to a 8033 1.1 jruoho single location for clarity and ease of maintenance. One new file was 8034 1.1 jruoho created, named "rsinfo.c". 8035 1.1 jruoho 8036 1.1 jruoho The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to 8037 1.1.1.3.2.1 yamt guarantee that the argument is not evaluated twice, making them less 8038 1.1.1.3.2.1 yamt prone 8039 1.1 jruoho to macro side-effects. However, since there exists the possibility of 8040 1.1.1.3.2.1 yamt additional stack use if a particular compiler cannot optimize them (such 8041 1.1.1.3.2.1 yamt as 8042 1.1.1.3.2.1 yamt in the debug generation case), the original macros are optionally 8043 1.1.1.3.2.1 yamt available. 8044 1.1 jruoho Note that some invocations of the return_VALUE macro may now cause size 8045 1.1.1.3.2.1 yamt mismatch warnings; the return_UINT8 and return_UINT32 macros are provided 8046 1.1.1.3.2.1 yamt to 8047 1.1 jruoho eliminate these. (From Randy Dunlap) 8048 1.1 jruoho 8049 1.1.1.3.2.1 yamt Implemented a new mechanism to enable debug tracing for individual 8050 1.1.1.3.2.1 yamt control 8051 1.1 jruoho methods. A new external interface, AcpiDebugTrace, is provided to enable 8052 1.1 jruoho this mechanism. The intent is to allow the host OS to easily enable and 8053 1.1 jruoho disable tracing for problematic control methods. This interface can be 8054 1.1 jruoho easily exposed to a user or debugger interface if desired. See the file 8055 1.1 jruoho psxface.c for details. 8056 1.1 jruoho 8057 1.1 jruoho AcpiUtCallocate will now return a valid pointer if a length of zero is 8058 1.1 jruoho specified - a length of one is used and a warning is issued. This matches 8059 1.1 jruoho the behavior of AcpiUtAllocate. 8060 1.1 jruoho 8061 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 8062 1.1 jruoho subsystem are shown below.

This descriptor is now 8092 1.1.1.3.2.1 yamt fully 8093 1.1 jruoho recognized, parsed, disassembled, and displayed. 8094 1.1 jruoho 8095 1.1 jruoho Completely restructured the Resource Manager code to utilize table-driven 8096 1.1.1.3.2.1 yamt dispatch and lookup, eliminating many of the large switch() statements. 8097 1.1.1.3.2.1 yamt This 8098 1.1 jruoho reduces overall subsystem code size and code complexity. Affects the 8099 1.1 jruoho resource parsing and construction, disassembly, and debug dump output. 8100 1.1 jruoho 8101 1.1 jruoho Cleaned up and restructured the debug dump output for all resource 8102 1.1 jruoho descriptors. Improved readability of the output and reduced code size. 8103 1.1 jruoho 8104 1.1 jruoho Fixed a problem where changes to internal data structures caused the 8105 1.1 jruoho optional ACPI_MUTEX_DEBUG code to fail compilation if specified. 8106 1.1 jruoho 8107 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 8108 1.1 jruoho subsystem are shown below.

Recursive method invocation depth is 8149 1.1 jruoho currently limited to 255. (Alexey Starikovskiy) 8150 1.1 jruoho 8151 1.1 jruoho Completely eliminated all vestiges of support for the "module-level 8152 1.1.1.3.2.1 yamt executable code" until this support is fully implemented and debugged. 8153 1.1.1.3.2.1 yamt This 8154 1.1 jruoho should eliminate the NO_RETURN_VALUE exceptions seen during table load on 8155 1.1 jruoho some systems that invoke this support. 8156 1.1 jruoho 8157 1.1.1.3.2.1 yamt Fixed a problem within the resource manager code where the transaction 8158 1.1.1.3.2.1 yamt flags 8159 1.1 jruoho for a 64-bit address descriptor were handled incorrectly in the type- 8160 1.1 jruoho specific flag byte. 8161 1.1 jruoho 8162 1.1.1.3.2.1 yamt Consolidated duplicate code within the address descriptor resource 8163 1.1.1.3.2.1 yamt manager 8164 1.1 jruoho code, reducing overall subsystem code size. 8165 1.1 jruoho 8166 1.1 jruoho Fixed a fault when using the AML debugger "disassemble" command to 8167 1.1 jruoho disassemble individual control methods. 8168 1.1 jruoho 8169 1.1 jruoho Removed references to the "release_current" directory within the Unix 8170 1.1 jruoho release package. 8171 1.1 jruoho 8172 1.1 jruoho Code and Data Size: The current and previous core subsystem library sizes 8173 1.1 jruoho are shown below.

Summary of changes for version 20050815: 8213 1.1 jruoho 8214 1.1 jruoho 1) ACPI CA Core Subsystem: 8215 1.1 jruoho 8216 1.1.1.3.2.1 yamt Implemented a full bytewise compare to determine if a table load request 8217 1.1.1.3.2.1 yamt is 8218 1.1.1.3.2.1 yamt attempting to load a duplicate table. The compare is performed if the 8219 1.1.1.3.2.1 yamt table 8220 1.1 jruoho signatures and table lengths match. This will allow different tables with 8221 1.1.1.3.2.1 yamt the same OEM Table ID and revision to be loaded - probably against the 8222 1.1.1.3.2.1 yamt ACPI 8223 1.1 jruoho specification, but discovered in the field nonetheless. 8224 1.1 jruoho 8225 1.1 jruoho Added the changes.txt logfile to each of the zipped release packages. 8226 1.1 jruoho 8227 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8228 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 8232 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8233 1.1.1.3.2.1 yamt Note 8234 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8235 1.1.1.3.2.1 yamt and 8236 1.1 jruoho the compiler options used during generation. 8237 1.1 jruoho 8238 1.1 jruoho Previous Release: 8239 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 8240 1.1 jruoho Debug Version: 167.0K Code, 69.9K Data, 236.9K Total 8241 1.1 jruoho Current Release: 8242 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 8243 1.1 jruoho Debug Version: 170.0K Code, 69.9K Data, 239.9K Total 8244 1.1 jruoho 8245 1.1 jruoho 8246 1.1 jruoho 2) iASL Compiler/Disassembler: 8247 1.1 jruoho 8248 1.1 jruoho Fixed a problem where incorrect AML code could be generated for Package 8249 1.1 jruoho objects if optimization is disabled (via the -oa switch). 8250 1.1 jruoho 8251 1.1 jruoho Fixed a problem with where incorrect AML code is generated for variable- 8252 1.1.1.3.2.1 yamt length packages when the package length is not specified and the number 8253 1.1.1.3.2.1 yamt of 8254 1.1 jruoho initializer values is greater than 255. 8255 1.1 jruoho 8256 1.1 jruoho 8257 1.1 jruoho ---------------------------------------- 8258 1.1 jruoho 29 July 2005. Summary of changes for version 20050729: 8259 1.1 jruoho 8260 1.1 jruoho 1) ACPI CA Core Subsystem: 8261 1.1 jruoho 8262 1.1.1.3.2.1 yamt Implemented support to ignore an attempt to install/load a particular 8263 1.1.1.3.2.1 yamt ACPI 8264 1.1 jruoho table more than once. Apparently there exists BIOS code that repeatedly 8265 1.1 jruoho attempts to load the same SSDT upon certain events. With assistance from 8266 1.1 jruoho Venkatesh Pallipadi. 8267 1.1 jruoho 8268 1.1 jruoho Restructured the main interface to the AML parser in order to correctly 8269 1.1.1.3.2.1 yamt handle all exceptional conditions. This will prevent leakage of the 8270 1.1.1.3.2.1 yamt OwnerId 8271 1.1.1.3.2.1 yamt resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on 8272 1.1.1.3.2.1 yamt some 8273 1.1 jruoho machines. With assistance from Alexey Starikovskiy. 8274 1.1 jruoho 8275 1.1.1.3.2.1 yamt Support for "module level code" has been disabled in this version due to 8276 1.1.1.3.2.1 yamt a 8277 1.1.1.3.2.1 yamt number of issues that have appeared on various machines. The support can 8278 1.1.1.3.2.1 yamt be 8279 1.1 jruoho enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem 8280 1.1.1.3.2.1 yamt compilation. When the issues are fully resolved, the code will be enabled 8281 1.1.1.3.2.1 yamt by 8282 1.1 jruoho default again. 8283 1.1 jruoho 8284 1.1 jruoho Modified the internal functions for debug print support to define the 8285 1.1.1.3.2.1 yamt FunctionName parameter as a (const char *) for compatibility with 8286 1.1.1.3.2.1 yamt compiler 8287 1.1 jruoho built-in macros such as __FUNCTION__, etc. 8288 1.1 jruoho 8289 1.1 jruoho Linted the entire ACPICA source tree for both 32-bit and 64-bit. 8290 1.1 jruoho 8291 1.1.1.3.2.1 yamt Implemented support to display an object count summary for the AML 8292 1.1.1.3.2.1 yamt Debugger 8293 1.1 jruoho commands Object and Methods. 8294 1.1 jruoho 8295 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8296 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 8300 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8301 1.1.1.3.2.1 yamt Note 8302 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8303 1.1.1.3.2.1 yamt and 8304 1.1 jruoho the compiler options used during generation. 8305 1.1 jruoho 8306 1.1 jruoho Previous Release: 8307 1.1 jruoho Non-Debug Version: 78.6K Code, 11.6K Data, 90.2K Total 8308 1.1 jruoho Debug Version: 170.0K Code, 69.7K Data, 239.7K Total 8309 1.1 jruoho Current Release: 8310 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 8311 1.1 jruoho Debug Version: 167.0K Code, 69.9K Data, 236.9K Total 8312 1.1 jruoho 8313 1.1 jruoho 8314 1.1 jruoho 2) iASL Compiler/Disassembler: 8315 1.1 jruoho 8316 1.1 jruoho Fixed a regression that appeared in the 20050708 version of the compiler 8317 1.1.1.3.2.1 yamt where an error message was inadvertently emitted for invocations of the 8318 1.1.1.3.2.1 yamt _OSI 8319 1.1 jruoho reserved control method. 8320 1.1 jruoho 8321 1.1 jruoho ---------------------------------------- 8322 1.1 jruoho 08 July 2005. Summary of changes for version 20050708: 8323 1.1 jruoho 8324 1.1 jruoho 1) ACPI CA Core Subsystem: 8325 1.1 jruoho 8326 1.1 jruoho The use of the CPU stack in the debug version of the subsystem has been 8327 1.1 jruoho considerably reduced. Previously, a debug structure was declared in every 8328 1.1 jruoho function that used the debug macros. This structure has been removed in 8329 1.1 jruoho favor of declaring the individual elements as parameters to the debug 8330 1.1.1.3.2.1 yamt functions. This reduces the cumulative stack use during nested execution 8331 1.1.1.3.2.1 yamt of 8332 1.1.1.3.2.1 yamt ACPI function calls at the cost of a small increase in the code size of 8333 1.1.1.3.2.1 yamt the 8334 1.1.1.3.2.1 yamt debug version of the subsystem. With assistance from Alexey Starikovskiy 8335 1.1.1.3.2.1 yamt and 8336 1.1 jruoho Len Brown. 8337 1.1 jruoho 8338 1.1 jruoho Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent 8339 1.1 jruoho headers to define a macro that will return the current function name at 8340 1.1.1.3.2.1 yamt runtime (such as __FUNCTION__ or _func_, etc.) The function name is used 8341 1.1.1.3.2.1 yamt by 8342 1.1 jruoho the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the 8343 1.1.1.3.2.1 yamt compiler-dependent header, the function name is saved on the CPU stack 8344 1.1.1.3.2.1 yamt (one 8345 1.1 jruoho pointer per function.) This mechanism is used because apparently there 8346 1.1.1.3.2.1 yamt exists no standard ANSI-C defined macro that that returns the function 8347 1.1.1.3.2.1 yamt name. 8348 1.1 jruoho 8349 1.1 jruoho Redesigned and reimplemented the "Owner ID" mechanism used to track 8350 1.1 jruoho namespace objects created/deleted by ACPI tables and control method 8351 1.1.1.3.2.1 yamt execution. A bitmap is now used to allocate and free the IDs, thus 8352 1.1.1.3.2.1 yamt solving 8353 1.1.1.3.2.1 yamt the wraparound problem present in the previous implementation. The size 8354 1.1.1.3.2.1 yamt of 8355 1.1 jruoho the namespace node descriptor was reduced by 2 bytes as a result (Alexey 8356 1.1 jruoho Starikovskiy). 8357 1.1 jruoho 8358 1.1.1.3.2.1 yamt Removed the UINT32_BIT and UINT16_BIT types that were used for the 8359 1.1.1.3.2.1 yamt bitfield 8360 1.1 jruoho flag definitions within the headers for the predefined ACPI tables. These 8361 1.1.1.3.2.1 yamt have been replaced by UINT8_BIT in order to increase the code portability 8362 1.1.1.3.2.1 yamt of 8363 1.1 jruoho the subsystem. If the use of UINT8 remains a problem, we may be forced to 8364 1.1 jruoho eliminate bitfields entirely because of a lack of portability. 8365 1.1 jruoho 8366 1.1.1.3.2.1 yamt Enhanced the performance of the AcpiUtUpdateObjectReference procedure. 8367 1.1.1.3.2.1 yamt This 8368 1.1.1.3.2.1 yamt is a frequently used function and this improvement increases the 8369 1.1.1.3.2.1 yamt performance 8370 1.1 jruoho of the entire subsystem (Alexey Starikovskiy). 8371 1.1 jruoho 8372 1.1 jruoho Fixed several possible memory leaks and the inverse - premature object 8373 1.1 jruoho deletion (Alexey Starikovskiy). 8374 1.1 jruoho 8375 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8376 1.1.1.3.2.1 yamt shown below.

This allows the OSL implementation to 8400 1.1.1.3.2.1 yamt define 8401 1.1 jruoho and type this object in any manner desired, simplifying the OSL 8402 1.1 jruoho implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for 8403 1.1 jruoho Linux, and should be defined in the OS-specific header file for other 8404 1.1 jruoho operating systems as required. 8405 1.1 jruoho 8406 1.1 jruoho Changed the interface to AcpiOsAcquireObject to directly return the 8407 1.1 jruoho requested object as the function return (instead of ACPI_STATUS.) This 8408 1.1 jruoho change was made for performance reasons, since this is the purpose of the 8409 1.1 jruoho interface in the first place. AcpiOsAcquireObject is now similar to the 8410 1.1 jruoho AcpiOsAllocate interface. 8411 1.1 jruoho 8412 1.1.1.3.2.1 yamt Implemented a new AML debugger command named Businfo. This command 8413 1.1.1.3.2.1 yamt displays 8414 1.1.1.3.2.1 yamt information about all devices that have an associate _PRT object. The 8415 1.1.1.3.2.1 yamt _ADR, 8416 1.1 jruoho _HID, _UID, and _CID are displayed for these devices. 8417 1.1 jruoho 8418 1.1.1.3.2.1 yamt Modified the initialization sequence in AcpiInitializeSubsystem to call 8419 1.1.1.3.2.1 yamt the 8420 1.1.1.3.2.1 yamt OSL interface AcpiOslInitialize first, before any local initialization. 8421 1.1.1.3.2.1 yamt This 8422 1.1 jruoho change was required because the global initialization now calls OSL 8423 1.1 jruoho interfaces. 8424 1.1 jruoho 8425 1.1.1.3.2.1 yamt Enhanced the Dump command to display the entire contents of Package 8426 1.1.1.3.2.1 yamt objects 8427 1.1 jruoho (including all sub-objects and their values.) 8428 1.1 jruoho 8429 1.1 jruoho Restructured the code base to split some files because of size and/or 8430 1.1.1.3.2.1 yamt because the code logically belonged in a separate file. New files are 8431 1.1.1.3.2.1 yamt listed 8432 1.1.1.3.2.1 yamt below. All makefiles and project files included in the ACPI CA release 8433 1.1.1.3.2.1 yamt have 8434 1.1 jruoho been updated. 8435 1.1 jruoho utilities/utcache.c /* Local cache interfaces */ 8436 1.1 jruoho utilities/utmutex.c /* Local mutex support */ 8437 1.1 jruoho utilities/utstate.c /* State object support */ 8438 1.1 jruoho interpreter/parser/psloop.c /* Main AML parse loop */ 8439 1.1 jruoho 8440 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8441 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8442 1.1.1.3.2.1 yamt produced 8443 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8444 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8445 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8446 1.1.1.3.2.1 yamt Note 8447 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8448 1.1.1.3.2.1 yamt and 8449 1.1 jruoho the compiler options used during generation. 8450 1.1 jruoho 8451 1.1 jruoho Previous Release: 8452 1.1 jruoho Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 8453 1.1 jruoho Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 8454 1.1 jruoho Current Release: 8455 1.1 jruoho Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total 8456 1.1 jruoho Debug Version: 165.2K Code, 69.6K Data, 234.8K Total 8457 1.1 jruoho 8458 1.1 jruoho 8459 1.1 jruoho 2) iASL Compiler/Disassembler: 8460 1.1 jruoho 8461 1.1.1.3.2.1 yamt Fixed a regression introduced in version 20050513 where the use of a 8462 1.1.1.3.2.1 yamt Package 8463 1.1 jruoho object within a Case() statement caused a compile time exception. The 8464 1.1 jruoho original behavior has been restored (a Match() operator is emitted.) 8465 1.1 jruoho 8466 1.1 jruoho ---------------------------------------- 8467 1.1 jruoho 17 June 2005. Summary of changes for version 20050617: 8468 1.1 jruoho 8469 1.1 jruoho 1) ACPI CA Core Subsystem: 8470 1.1 jruoho 8471 1.1.1.3.2.1 yamt Moved the object cache operations into the OS interface layer (OSL) to 8472 1.1.1.3.2.1 yamt allow 8473 1.1 jruoho the host OS to handle these operations if desired (for example, the Linux 8474 1.1.1.3.2.1 yamt OSL will invoke the slab allocator). This support is optional; the 8475 1.1.1.3.2.1 yamt compile 8476 1.1.1.3.2.1 yamt time define ACPI_USE_LOCAL_CACHE may be used to utilize the original 8477 1.1.1.3.2.1 yamt cache 8478 1.1 jruoho code in the ACPI CA core. The new OSL interfaces are shown below. See 8479 1.1 jruoho utalloc.c for an example implementation, and acpiosxf.h for the exact 8480 1.1 jruoho interface definitions. With assistance from Alexey Starikovskiy. 8481 1.1 jruoho AcpiOsCreateCache 8482 1.1 jruoho AcpiOsDeleteCache 8483 1.1 jruoho AcpiOsPurgeCache 8484 1.1 jruoho AcpiOsAcquireObject 8485 1.1 jruoho AcpiOsReleaseObject 8486 1.1 jruoho 8487 1.1.1.3.2.1 yamt Modified the interfaces to AcpiOsAcquireLock and AcpiOsReleaseLock to 8488 1.1.1.3.2.1 yamt return 8489 1.1 jruoho and restore a flags parameter. This fits better with many OS lock models. 8490 1.1 jruoho Note: the current execution state (interrupt handler or not) is no longer 8491 1.1.1.3.2.1 yamt passed to these interfaces. If necessary, the OSL must determine this 8492 1.1.1.3.2.1 yamt state 8493 1.1 jruoho by itself, a simple and fast operation. With assistance from Alexey 8494 1.1 jruoho Starikovskiy. 8495 1.1 jruoho 8496 1.1 jruoho Fixed a problem in the ACPI table handling where a valid XSDT was assumed 8497 1.1.1.3.2.1 yamt present if the revision of the RSDP was 2 or greater. According to the 8498 1.1.1.3.2.1 yamt ACPI 8499 1.1 jruoho specification, the XSDT is optional in all cases, and the table manager 8500 1.1 jruoho therefore now checks for both an RSDP >=2 and a valid XSDT pointer. 8501 1.1.1.3.2.1 yamt Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs 8502 1.1.1.3.2.1 yamt contain 8503 1.1 jruoho only the RSDT. 8504 1.1 jruoho 8505 1.1.1.3.2.1 yamt Fixed an interpreter problem with the Mid() operator in the case of an 8506 1.1.1.3.2.1 yamt input 8507 1.1.1.3.2.1 yamt string where the resulting output string is of zero length. It now 8508 1.1.1.3.2.1 yamt correctly 8509 1.1 jruoho returns a valid, null terminated string object instead of a string object 8510 1.1 jruoho with a null pointer. 8511 1.1 jruoho 8512 1.1.1.3.2.1 yamt Fixed a problem with the control method argument handling to allow a 8513 1.1.1.3.2.1 yamt store 8514 1.1.1.3.2.1 yamt to an Arg object that already contains an object of type Device. The 8515 1.1.1.3.2.1 yamt Device 8516 1.1 jruoho object is now correctly overwritten. Previously, an error was returned. 8517 1.1 jruoho 8518 1.1 jruoho 8519 1.1.1.3.2.1 yamt Enhanced the debugger Find command to emit object values in addition to 8520 1.1.1.3.2.1 yamt the 8521 1.1.1.3.2.1 yamt found object pathnames. The output format is the same as the dump 8522 1.1.1.3.2.1 yamt namespace 8523 1.1 jruoho command. 8524 1.1 jruoho 8525 1.1.1.3.2.1 yamt Enhanced the debugger Set command. It now has the ability to set the 8526 1.1.1.3.2.1 yamt value 8527 1.1.1.3.2.1 yamt of any Named integer object in the namespace (Previously, only method 8528 1.1.1.3.2.1 yamt locals 8529 1.1 jruoho and args could be set.) 8530 1.1 jruoho 8531 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8532 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8533 1.1.1.3.2.1 yamt produced 8534 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8535 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8536 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8537 1.1.1.3.2.1 yamt Note 8538 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8539 1.1.1.3.2.1 yamt and 8540 1.1 jruoho the compiler options used during generation. 8541 1.1 jruoho 8542 1.1 jruoho Previous Release: 8543 1.1 jruoho Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 8544 1.1 jruoho Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 8545 1.1 jruoho Current Release: 8546 1.1 jruoho Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 8547 1.1 jruoho Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 8548 1.1 jruoho 8549 1.1 jruoho 8550 1.1 jruoho 2) iASL Compiler/Disassembler: 8551 1.1 jruoho 8552 1.1.1.3.2.1 yamt Fixed a regression in the disassembler where if/else/while constructs 8553 1.1.1.3.2.1 yamt were 8554 1.1 jruoho output incorrectly. This problem was introduced in the previous release 8555 1.1 jruoho (20050526). This problem also affected the single-step disassembly in the 8556 1.1 jruoho debugger. 8557 1.1 jruoho 8558 1.1.1.3.2.1 yamt Fixed a problem where compiling the reserved _OSI method would randomly 8559 1.1.1.3.2.1 yamt (but 8560 1.1 jruoho rarely) produce compile errors. 8561 1.1 jruoho 8562 1.1.1.3.2.1 yamt Enhanced the disassembler to emit compilable code in the face of 8563 1.1.1.3.2.1 yamt incorrect 8564 1.1 jruoho AML resource descriptors. If the optional ResourceSourceIndex is present, 8565 1.1 jruoho but the ResourceSource is not, do not emit the ResourceSourceIndex in the 8566 1.1 jruoho disassembly. Otherwise, the resulting code cannot be compiled without 8567 1.1 jruoho errors. 8568 1.1 jruoho 8569 1.1 jruoho ---------------------------------------- 8570 1.1 jruoho 26 May 2005. Summary of changes for version 20050526: 8571 1.1 jruoho 8572 1.1 jruoho 1) ACPI CA Core Subsystem: 8573 1.1 jruoho 8574 1.1 jruoho Implemented support to execute Type 1 and Type 2 AML opcodes appearing at 8575 1.1.1.3.2.1 yamt the module level (not within a control method.) These opcodes are 8576 1.1.1.3.2.1 yamt executed 8577 1.1.1.3.2.1 yamt exactly once at the time the table is loaded. This type of code was legal 8578 1.1.1.3.2.1 yamt up 8579 1.1.1.3.2.1 yamt until the release of ACPI 2.0B (2002) and is now supported within ACPI CA 8580 1.1.1.3.2.1 yamt in 8581 1.1.1.3.2.1 yamt order to provide backwards compatibility with earlier BIOS 8582 1.1.1.3.2.1 yamt implementations. 8583 1.1 jruoho This eliminates the "Encountered executable code at module level" warning 8584 1.1 jruoho that was previously generated upon detection of such code. 8585 1.1 jruoho 8586 1.1 jruoho Fixed a problem in the interpreter where an AE_NOT_FOUND exception could 8587 1.1 jruoho inadvertently be generated during the lookup of namespace objects in the 8588 1.1.1.3.2.1 yamt second pass parse of ACPI tables and control methods. It appears that 8589 1.1.1.3.2.1 yamt this 8590 1.1.1.3.2.1 yamt problem could occur during the resolution of forward references to 8591 1.1.1.3.2.1 yamt namespace 8592 1.1 jruoho objects. 8593 1.1 jruoho 8594 1.1 jruoho Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function, 8595 1.1 jruoho corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This 8596 1.1 jruoho allows the deadlock detection debug code to be compiled out in the normal 8597 1.1 jruoho case, improving mutex performance (and overall subsystem performance) 8598 1.1 jruoho considerably. 8599 1.1 jruoho 8600 1.1 jruoho Implemented a handful of miscellaneous fixes for possible memory leaks on 8601 1.1 jruoho error conditions and error handling control paths. These fixes were 8602 1.1 jruoho suggested by FreeBSD and the Coverity Prevent source code analysis tool. 8603 1.1 jruoho 8604 1.1.1.3.2.1 yamt Added a check for a null RSDT pointer in AcpiGetFirmwareTable 8605 1.1.1.3.2.1 yamt (tbxfroot.c) 8606 1.1 jruoho to prevent a fault in this error case. 8607 1.1 jruoho 8608 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8609 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8610 1.1.1.3.2.1 yamt produced 8611 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8612 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8613 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8614 1.1.1.3.2.1 yamt Note 8615 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8616 1.1.1.3.2.1 yamt and 8617 1.1 jruoho the compiler options used during generation. 8618 1.1 jruoho 8619 1.1 jruoho Previous Release: 8620 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 8621 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 8622 1.1 jruoho Current Release: 8623 1.1 jruoho Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 8624 1.1 jruoho Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 8625 1.1 jruoho 8626 1.1 jruoho 8627 1.1 jruoho 2) iASL Compiler/Disassembler: 8628 1.1 jruoho 8629 1.1 jruoho Implemented support to allow Type 1 and Type 2 ASL operators to appear at 8630 1.1 jruoho the module level (not within a control method.) These operators will be 8631 1.1.1.3.2.1 yamt executed once at the time the table is loaded. This type of code was 8632 1.1.1.3.2.1 yamt legal 8633 1.1 jruoho up until the release of ACPI 2.0B (2002) and is now supported by the iASL 8634 1.1.1.3.2.1 yamt compiler in order to provide backwards compatibility with earlier BIOS 8635 1.1.1.3.2.1 yamt ASL 8636 1.1 jruoho code. 8637 1.1 jruoho 8638 1.1 jruoho The ACPI integer width (specified via the table revision ID or the -r 8639 1.1.1.3.2.1 yamt override, 32 or 64 bits) is now used internally during compile-time 8640 1.1.1.3.2.1 yamt constant 8641 1.1 jruoho folding to ensure that constants are truncated to 32 bits if necessary. 8642 1.1.1.3.2.1 yamt Previously, the revision ID value was only emitted in the AML table 8643 1.1.1.3.2.1 yamt header. 8644 1.1 jruoho 8645 1.1.1.3.2.1 yamt An error message is now generated for the Mutex and Method operators if 8646 1.1.1.3.2.1 yamt the 8647 1.1 jruoho SyncLevel parameter is outside the legal range of 0 through 15. 8648 1.1 jruoho 8649 1.1.1.3.2.1 yamt Fixed a problem with the Method operator ParameterTypes list handling 8650 1.1.1.3.2.1 yamt (ACPI 8651 1.1.1.3.2.1 yamt 3.0). Previously, more than 2 types or 2 arguments generated a syntax 8652 1.1.1.3.2.1 yamt error. 8653 1.1 jruoho The actual underlying implementation of method argument typechecking is 8654 1.1 jruoho still under development, however. 8655 1.1 jruoho 8656 1.1 jruoho ---------------------------------------- 8657 1.1 jruoho 13 May 2005. Summary of changes for version 20050513: 8658 1.1 jruoho 8659 1.1 jruoho 1) ACPI CA Core Subsystem: 8660 1.1 jruoho 8661 1.1.1.3.2.1 yamt Implemented support for PCI Express root bridges -- added support for 8662 1.1.1.3.2.1 yamt device 8663 1.1 jruoho PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup. 8664 1.1 jruoho 8665 1.1.1.3.2.1 yamt The interpreter now automatically truncates incoming 64-bit constants to 8666 1.1.1.3.2.1 yamt 32 8667 1.1.1.3.2.1 yamt bits if currently executing out of a 32-bit ACPI table (Revision < 2). 8668 1.1.1.3.2.1 yamt This 8669 1.1 jruoho also affects the iASL compiler constant folding. (Note: as per below, the 8670 1.1 jruoho iASL compiler no longer allows 64-bit constants within 32-bit tables.) 8671 1.1 jruoho 8672 1.1 jruoho Fixed a problem where string and buffer objects with "static" pointers 8673 1.1 jruoho (pointers to initialization data within an ACPI table) were not handled 8674 1.1.1.3.2.1 yamt consistently. The internal object copy operation now always copies the 8675 1.1.1.3.2.1 yamt data 8676 1.1 jruoho to a newly allocated buffer, regardless of whether the source object is 8677 1.1 jruoho static or not. 8678 1.1 jruoho 8679 1.1 jruoho Fixed a problem with the FromBCD operator where an implicit result 8680 1.1.1.3.2.1 yamt conversion was improperly performed while storing the result to the 8681 1.1.1.3.2.1 yamt target 8682 1.1 jruoho operand. Since this is an "explicit conversion" operator, the implicit 8683 1.1 jruoho conversion should never be performed on the output. 8684 1.1 jruoho 8685 1.1 jruoho Fixed a problem with the CopyObject operator where a copy to an existing 8686 1.1.1.3.2.1 yamt named object did not always completely overwrite the existing object 8687 1.1.1.3.2.1 yamt stored 8688 1.1.1.3.2.1 yamt at name. Specifically, a buffer-to-buffer copy did not delete the 8689 1.1.1.3.2.1 yamt existing 8690 1.1 jruoho buffer. 8691 1.1 jruoho 8692 1.1.1.3.2.1 yamt Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces 8693 1.1.1.3.2.1 yamt and 8694 1.1 jruoho structs for consistency. 8695 1.1 jruoho 8696 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8697 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8698 1.1.1.3.2.1 yamt produced 8699 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8700 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8701 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8702 1.1.1.3.2.1 yamt Note 8703 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8704 1.1.1.3.2.1 yamt and 8705 1.1 jruoho the compiler options used during generation. 8706 1.1 jruoho 8707 1.1 jruoho Previous Release: 8708 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 8709 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 8710 1.1 jruoho Current Release: (Same sizes) 8711 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 8712 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 8713 1.1 jruoho 8714 1.1 jruoho 8715 1.1 jruoho 2) iASL Compiler/Disassembler: 8716 1.1 jruoho 8717 1.1.1.3.2.1 yamt The compiler now emits a warning if an attempt is made to generate a 64- 8718 1.1.1.3.2.1 yamt bit 8719 1.1.1.3.2.1 yamt integer constant from within a 32-bit ACPI table (Revision < 2). The 8720 1.1.1.3.2.1 yamt integer 8721 1.1 jruoho is truncated to 32 bits. 8722 1.1 jruoho 8723 1.1 jruoho Fixed a problem with large package objects: if the static length of the 8724 1.1 jruoho package is greater than 255, the "variable length package" opcode is 8725 1.1 jruoho emitted. Previously, this caused an error. This requires an update to the 8726 1.1.1.3.2.1 yamt ACPI spec, since it currently (incorrectly) states that packages larger 8727 1.1.1.3.2.1 yamt than 8728 1.1 jruoho 255 elements are not allowed. 8729 1.1 jruoho 8730 1.1.1.3.2.1 yamt The disassembler now correctly handles variable length packages and 8731 1.1.1.3.2.1 yamt packages 8732 1.1 jruoho larger than 255 elements. 8733 1.1 jruoho 8734 1.1 jruoho ---------------------------------------- 8735 1.1 jruoho 08 April 2005. Summary of changes for version 20050408: 8736 1.1 jruoho 8737 1.1 jruoho 1) ACPI CA Core Subsystem: 8738 1.1 jruoho 8739 1.1 jruoho Fixed three cases in the interpreter where an "index" argument to an ASL 8740 1.1 jruoho function was still (internally) 32 bits instead of the required 64 bits. 8741 1.1 jruoho This was the Index argument to the Index, Mid, and Match operators. 8742 1.1 jruoho 8743 1.1.1.3.2.1 yamt The "strupr" function is now permanently local (AcpiUtStrupr), since this 8744 1.1.1.3.2.1 yamt is 8745 1.1 jruoho not a POSIX-defined function and not present in most kernel-level C 8746 1.1.1.3.2.1 yamt libraries. All references to the C library strupr function have been 8747 1.1.1.3.2.1 yamt removed 8748 1.1 jruoho from the headers. 8749 1.1 jruoho 8750 1.1.1.3.2.1 yamt Completed the deployment of static functions/prototypes. All prototypes 8751 1.1.1.3.2.1 yamt with 8752 1.1.1.3.2.1 yamt the static attribute have been moved from the headers to the owning C 8753 1.1.1.3.2.1 yamt file. 8754 1.1 jruoho 8755 1.1 jruoho Implemented an extract option (-e) for the AcpiBin utility (AML binary 8756 1.1.1.3.2.1 yamt utility). This option allows the utility to extract individual ACPI 8757 1.1.1.3.2.1 yamt tables 8758 1.1 jruoho from the output of AcpiDmp. It provides the same functionality of the 8759 1.1 jruoho acpixtract.pl perl script without the worry of setting the correct perl 8760 1.1.1.3.2.1 yamt options. AcpiBin runs on Windows and has not yet been generated/validated 8761 1.1.1.3.2.1 yamt in 8762 1.1 jruoho the Linux/Unix environment (but should be soon). 8763 1.1 jruoho 8764 1.1 jruoho Updated and fixed the table dump option for AcpiBin (-d). This option 8765 1.1.1.3.2.1 yamt converts a single ACPI table to a hex/ascii file, similar to the output 8766 1.1.1.3.2.1 yamt of 8767 1.1 jruoho AcpiDmp. 8768 1.1 jruoho 8769 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8770 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8771 1.1.1.3.2.1 yamt produced 8772 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8773 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8774 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8775 1.1.1.3.2.1 yamt Note 8776 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8777 1.1.1.3.2.1 yamt and 8778 1.1 jruoho the compiler options used during generation. 8779 1.1 jruoho 8780 1.1 jruoho Previous Release: 8781 1.1 jruoho Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total 8782 1.1 jruoho Debug Version: 163.5K Code, 69.3K Data, 232.8K Total 8783 1.1 jruoho Current Release: 8784 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 8785 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 8786 1.1 jruoho 8787 1.1 jruoho 8788 1.1 jruoho 2) iASL Compiler/Disassembler: 8789 1.1 jruoho 8790 1.1.1.3.2.1 yamt Disassembler fix: Added a check to ensure that the table length found in 8791 1.1.1.3.2.1 yamt the 8792 1.1.1.3.2.1 yamt ACPI table header within the input file is not longer than the actual 8793 1.1.1.3.2.1 yamt input 8794 1.1 jruoho file size. This indicates some kind of file or table corruption. 8795 1.1 jruoho 8796 1.1 jruoho ---------------------------------------- 8797 1.1 jruoho 29 March 2005. Summary of changes for version 20050329: 8798 1.1 jruoho 8799 1.1 jruoho 1) ACPI CA Core Subsystem: 8800 1.1 jruoho 8801 1.1.1.3.2.1 yamt An error is now generated if an attempt is made to create a Buffer Field 8802 1.1.1.3.2.1 yamt of 8803 1.1 jruoho length zero (A CreateField with a length operand of zero.) 8804 1.1 jruoho 8805 1.1.1.3.2.1 yamt The interpreter now issues a warning whenever executable code at the 8806 1.1.1.3.2.1 yamt module 8807 1.1 jruoho level is detected during ACPI table load. This will give some idea of the 8808 1.1 jruoho prevalence of this type of code. 8809 1.1 jruoho 8810 1.1 jruoho Implemented support for references to named objects (other than control 8811 1.1 jruoho methods) within package objects. 8812 1.1 jruoho 8813 1.1.1.3.2.1 yamt Enhanced package object output for the debug object. Package objects are 8814 1.1.1.3.2.1 yamt now 8815 1.1 jruoho completely dumped, showing all elements. 8816 1.1 jruoho 8817 1.1 jruoho Enhanced miscellaneous object output for the debug object. Any object can 8818 1.1 jruoho now be written to the debug object (for example, a device object can be 8819 1.1 jruoho written, and the type of the object will be displayed.) 8820 1.1 jruoho 8821 1.1.1.3.2.1 yamt The "static" qualifier has been added to all local functions across both 8822 1.1.1.3.2.1 yamt the 8823 1.1 jruoho core subsystem and the iASL compiler. 8824 1.1 jruoho 8825 1.1 jruoho The number of "long" lines (> 80 chars) within the source has been 8826 1.1 jruoho significantly reduced, by about 1/3. 8827 1.1 jruoho 8828 1.1 jruoho Cleaned up all header files to ensure that all CA/iASL functions are 8829 1.1 jruoho prototyped (even static functions) and the formatting is consistent. 8830 1.1 jruoho 8831 1.1 jruoho Two new header files have been added, acopcode.h and acnames.h. 8832 1.1 jruoho 8833 1.1 jruoho Removed several obsolete functions that were no longer used. 8834 1.1 jruoho 8835 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8836 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8837 1.1.1.3.2.1 yamt produced 8838 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8839 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8840 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8841 1.1.1.3.2.1 yamt Note 8842 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8843 1.1.1.3.2.1 yamt and 8844 1.1 jruoho the compiler options used during generation. 8845 1.1 jruoho 8846 1.1 jruoho Previous Release: 8847 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 8848 1.1 jruoho Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 8849 1.1 jruoho Current Release: 8850 1.1 jruoho Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total 8851 1.1 jruoho Debug Version: 163.5K Code, 69.3K Data, 232.8K Total 8852 1.1 jruoho 8853 1.1 jruoho 8854 1.1 jruoho 8855 1.1 jruoho 2) iASL Compiler/Disassembler: 8856 1.1 jruoho 8857 1.1 jruoho Fixed a problem with the resource descriptor generation/support. For the 8858 1.1.1.3.2.1 yamt ResourceSourceIndex and the ResourceSource fields, both must be present, 8859 1.1.1.3.2.1 yamt or 8860 1.1 jruoho both must be not present - can't have one without the other. 8861 1.1 jruoho 8862 1.1.1.3.2.1 yamt The compiler now returns non-zero from the main procedure if any errors 8863 1.1.1.3.2.1 yamt have 8864 1.1 jruoho occurred during the compilation. 8865 1.1 jruoho 8866 1.1 jruoho 8867 1.1 jruoho ---------------------------------------- 8868 1.1 jruoho 09 March 2005. Summary of changes for version 20050309: 8869 1.1 jruoho 8870 1.1 jruoho 1) ACPI CA Core Subsystem: 8871 1.1 jruoho 8872 1.1.1.3.2.1 yamt The string-to-buffer implicit conversion code has been modified again 8873 1.1.1.3.2.1 yamt after 8874 1.1.1.3.2.1 yamt a change to the ACPI specification. In order to match the behavior of 8875 1.1.1.3.2.1 yamt the 8876 1.1.1.3.2.1 yamt other major ACPI implementation, the target buffer is no longer truncated 8877 1.1.1.3.2.1 yamt if 8878 1.1 jruoho the source string is smaller than an existing target buffer. This change 8879 1.1 jruoho requires an update to the ACPI spec, and should eliminate the recent 8880 1.1 jruoho AE_AML_BUFFER_LIMIT issues. 8881 1.1 jruoho 8882 1.1.1.3.2.1 yamt The "implicit return" support was rewritten to a new algorithm that 8883 1.1.1.3.2.1 yamt solves 8884 1.1.1.3.2.1 yamt the general case. Rather than attempt to determine when a method is about 8885 1.1.1.3.2.1 yamt to 8886 1.1.1.3.2.1 yamt exit, the result of every ASL operator is saved momentarily until the 8887 1.1.1.3.2.1 yamt very 8888 1.1 jruoho next ASL operator is executed. Therefore, no matter how the method exits, 8889 1.1 jruoho there will always be a saved implicit return value. This feature is only 8890 1.1.1.3.2.1 yamt enabled with the AcpiGbl_EnableInterpreterSlack flag, and should 8891 1.1.1.3.2.1 yamt eliminate 8892 1.1 jruoho AE_AML_NO_RETURN_VALUE errors when enabled. 8893 1.1 jruoho 8894 1.1.1.3.2.1 yamt Implemented implicit conversion support for the predicate (operand) of 8895 1.1.1.3.2.1 yamt the 8896 1.1.1.3.2.1 yamt If, Else, and While operators. String and Buffer arguments are 8897 1.1.1.3.2.1 yamt automatically 8898 1.1 jruoho converted to Integers. 8899 1.1 jruoho 8900 1.1 jruoho Changed the string-to-integer conversion behavior to match the new ACPI 8901 1.1 jruoho errata: "If no integer object exists, a new integer is created. The ASCII 8902 1.1 jruoho string is interpreted as a hexadecimal constant. Each string character is 8903 1.1 jruoho interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting 8904 1.1.1.3.2.1 yamt with the first character as the most significant digit, and ending with 8905 1.1.1.3.2.1 yamt the 8906 1.1.1.3.2.1 yamt first non-hexadecimal character or end-of-string." This means that the 8907 1.1.1.3.2.1 yamt first 8908 1.1 jruoho non-hex character terminates the conversion and this is the code that was 8909 1.1 jruoho changed. 8910 1.1 jruoho 8911 1.1.1.3.2.1 yamt Fixed a problem where the ObjectType operator would fail (fault) when 8912 1.1.1.3.2.1 yamt used 8913 1.1 jruoho on an Index of a Package which pointed to a null package element. The 8914 1.1 jruoho operator now properly returns zero (Uninitialized) in this case. 8915 1.1 jruoho 8916 1.1 jruoho Fixed a problem where the While operator used excessive memory by not 8917 1.1.1.3.2.1 yamt properly popping the result stack during execution. There was no memory 8918 1.1.1.3.2.1 yamt leak 8919 1.1 jruoho after execution, however. (Code provided by Valery Podrezov.) 8920 1.1 jruoho 8921 1.1.1.3.2.1 yamt Fixed a problem where references to control methods within Package 8922 1.1.1.3.2.1 yamt objects 8923 1.1 jruoho caused the method to be invoked, instead of producing a reference object 8924 1.1 jruoho pointing to the method. 8925 1.1 jruoho 8926 1.1.1.3.2.1 yamt Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) 8927 1.1.1.3.2.1 yamt to 8928 1.1 jruoho improve performance and reduce code size. (Code provided by Alexey 8929 1.1 jruoho Starikovskiy.) 8930 1.1 jruoho 8931 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 8932 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 8933 1.1.1.3.2.1 yamt produced 8934 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 8935 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 8936 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 8937 1.1.1.3.2.1 yamt Note 8938 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 8939 1.1.1.3.2.1 yamt and 8940 1.1 jruoho the compiler options used during generation. 8941 1.1 jruoho 8942 1.1 jruoho Previous Release: 8943 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 8944 1.1 jruoho Debug Version: 165.4K Code, 69.6K Data, 236.0K Total 8945 1.1 jruoho Current Release: 8946 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 8947 1.1 jruoho Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 8948 1.1 jruoho 8949 1.1 jruoho 8950 1.1 jruoho 2) iASL Compiler/Disassembler: 8951 1.1 jruoho 8952 1.1 jruoho Fixed a problem with the Return operator with no arguments. Since the AML 8953 1.1.1.3.2.1 yamt grammar for the byte encoding requires an operand for the Return opcode, 8954 1.1.1.3.2.1 yamt the 8955 1.1 jruoho compiler now emits a Return(Zero) for this case. An ACPI specification 8956 1.1 jruoho update has been written for this case. 8957 1.1 jruoho 8958 1.1 jruoho For tables other than the DSDT, namepath optimization is automatically 8959 1.1.1.3.2.1 yamt disabled. This is because SSDTs can be loaded anywhere in the namespace, 8960 1.1.1.3.2.1 yamt the 8961 1.1 jruoho compiler has no knowledge of where, and thus cannot optimize namepaths. 8962 1.1 jruoho 8963 1.1 jruoho Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was 8964 1.1 jruoho inadvertently omitted from the ACPI specification, and will require an 8965 1.1 jruoho update to the spec. 8966 1.1 jruoho 8967 1.1.1.3.2.1 yamt The source file scan for ASCII characters is now optional (-a). This 8968 1.1.1.3.2.1 yamt change 8969 1.1 jruoho was made because some vendors place non-ascii characters within comments. 8970 1.1 jruoho However, the scan is simply a brute-force byte compare to ensure all 8971 1.1 jruoho characters in the file are in the range 0x00 to 0x7F. 8972 1.1 jruoho 8973 1.1 jruoho Fixed a problem with the CondRefOf operator where the compiler was 8974 1.1.1.3.2.1 yamt inappropriately checking for the existence of the target. Since the point 8975 1.1.1.3.2.1 yamt of 8976 1.1 jruoho the operator is to check for the existence of the target at run-time, the 8977 1.1 jruoho compiler no longer checks for the target existence. 8978 1.1 jruoho 8979 1.1 jruoho Fixed a problem where errors generated from the internal AML interpreter 8980 1.1 jruoho during constant folding were not handled properly, causing a fault. 8981 1.1 jruoho 8982 1.1 jruoho Fixed a problem with overly aggressive range checking for the Stall 8983 1.1.1.3.2.1 yamt operator. The valid range (max 255) is now only checked if the operand is 8984 1.1.1.3.2.1 yamt of 8985 1.1 jruoho type Integer. All other operand types cannot be statically checked. 8986 1.1 jruoho 8987 1.1.1.3.2.1 yamt Fixed a problem where control method references within the RefOf, 8988 1.1.1.3.2.1 yamt DeRefOf, 8989 1.1.1.3.2.1 yamt and ObjectType operators were not treated properly. They are now treated 8990 1.1.1.3.2.1 yamt as 8991 1.1 jruoho actual references, not method invocations. 8992 1.1 jruoho 8993 1.1.1.3.2.1 yamt Fixed and enhanced the "list namespace" option (-ln). This option was 8994 1.1.1.3.2.1 yamt broken 8995 1.1 jruoho a number of releases ago. 8996 1.1 jruoho 8997 1.1.1.3.2.1 yamt Improved error handling for the Field, IndexField, and BankField 8998 1.1.1.3.2.1 yamt operators. 8999 1.1 jruoho The compiler now cleanly reports and recovers from errors in the field 9000 1.1 jruoho component (FieldUnit) list. 9001 1.1 jruoho 9002 1.1 jruoho Fixed a disassembler problem where the optional ResourceDescriptor fields 9003 1.1 jruoho TRS and TTP were not always handled correctly. 9004 1.1 jruoho 9005 1.1 jruoho Disassembler - Comments in output now use "//" instead of "/*" 9006 1.1 jruoho 9007 1.1 jruoho ---------------------------------------- 9008 1.1 jruoho 28 February 2005. Summary of changes for version 20050228: 9009 1.1 jruoho 9010 1.1 jruoho 1) ACPI CA Core Subsystem: 9011 1.1 jruoho 9012 1.1 jruoho Fixed a problem where the result of an Index() operator (an object 9013 1.1.1.3.2.1 yamt reference) must increment the reference count on the target object for 9014 1.1.1.3.2.1 yamt the 9015 1.1 jruoho life of the object reference. 9016 1.1 jruoho 9017 1.1 jruoho Implemented AML Interpreter and Debugger support for the new ACPI 3.0 9018 1.1.1.3.2.1 yamt Extended Address (IO, Memory, Space), QwordSpace, DwordSpace, and 9019 1.1.1.3.2.1 yamt WordSpace 9020 1.1 jruoho resource descriptors. 9021 1.1 jruoho 9022 1.1 jruoho Implemented support in the _OSI method for the ACPI 3.0 "Extended Address 9023 1.1.1.3.2.1 yamt Space Descriptor" string, indicating interpreter support for the 9024 1.1.1.3.2.1 yamt descriptors 9025 1.1 jruoho above. 9026 1.1 jruoho 9027 1.1 jruoho Implemented header support for the new ACPI 3.0 FADT flag bits. 9028 1.1 jruoho 9029 1.1.1.3.2.1 yamt Implemented header support for the new ACPI 3.0 PCI Express bits for the 9030 1.1.1.3.2.1 yamt PM1 9031 1.1 jruoho status/enable registers. 9032 1.1 jruoho 9033 1.1 jruoho Updated header support for the MADT processor local Apic struct and MADT 9034 1.1 jruoho platform interrupt source struct for new ACPI 3.0 fields. 9035 1.1 jruoho 9036 1.1 jruoho Implemented header support for the SRAT and SLIT ACPI tables. 9037 1.1 jruoho 9038 1.1.1.3.2.1 yamt Implemented the -s switch in AcpiExec to enable the "InterpreterSlack" 9039 1.1.1.3.2.1 yamt flag 9040 1.1 jruoho at runtime. 9041 1.1 jruoho 9042 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9043 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9044 1.1.1.3.2.1 yamt produced 9045 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9046 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9047 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9048 1.1.1.3.2.1 yamt Note 9049 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9050 1.1.1.3.2.1 yamt and 9051 1.1 jruoho the compiler options used during generation. 9052 1.1 jruoho 9053 1.1 jruoho Previous Release: 9054 1.1 jruoho Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total 9055 1.1 jruoho Debug Version: 164.9K Code, 69.2K Data, 234.1K Total 9056 1.1 jruoho Current Release: 9057 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 9058 1.1 jruoho Debug Version: 165.4K Code, 69.6K Data, 236.0K Total 9059 1.1 jruoho 9060 1.1 jruoho 9061 1.1 jruoho 2) iASL Compiler/Disassembler: 9062 1.1 jruoho 9063 1.1.1.3.2.1 yamt Fixed a problem with the internal 64-bit String-to-integer conversion 9064 1.1.1.3.2.1 yamt with 9065 1.1 jruoho strings less than two characters long. 9066 1.1 jruoho 9067 1.1 jruoho Fixed a problem with constant folding where the result of the Index() 9068 1.1.1.3.2.1 yamt operator can not be considered a constant. This means that Index() cannot 9069 1.1.1.3.2.1 yamt be 9070 1.1 jruoho a type3 opcode and this will require an update to the ACPI specification. 9071 1.1 jruoho 9072 1.1 jruoho Disassembler: Implemented support for the TTP, MTP, and TRS resource 9073 1.1.1.3.2.1 yamt descriptor fields. These fields were inadvertently ignored and not output 9074 1.1.1.3.2.1 yamt in 9075 1.1 jruoho the disassembly of the resource descriptor. 9076 1.1 jruoho 9077 1.1 jruoho 9078 1.1 jruoho ---------------------------------------- 9079 1.1 jruoho 11 February 2005. Summary of changes for version 20050211: 9080 1.1 jruoho 9081 1.1 jruoho 1) ACPI CA Core Subsystem: 9082 1.1 jruoho 9083 1.1 jruoho Implemented ACPI 3.0 support for implicit conversion within the Match() 9084 1.1.1.3.2.1 yamt operator. MatchObjects can now be of type integer, buffer, or string 9085 1.1.1.3.2.1 yamt instead 9086 1.1.1.3.2.1 yamt of just type integer. Package elements are implicitly converted to the 9087 1.1.1.3.2.1 yamt type 9088 1.1 jruoho of the MatchObject. This change aligns the behavior of Match() with the 9089 1.1.1.3.2.1 yamt behavior of the other logical operators (LLess(), etc.) It also requires 9090 1.1.1.3.2.1 yamt an 9091 1.1 jruoho errata change to the ACPI specification as this support was intended for 9092 1.1 jruoho ACPI 3.0, but was inadvertently omitted. 9093 1.1 jruoho 9094 1.1.1.3.2.1 yamt Fixed a problem with the internal implicit "to buffer" conversion. 9095 1.1.1.3.2.1 yamt Strings 9096 1.1.1.3.2.1 yamt that are converted to buffers will cause buffer truncation if the string 9097 1.1.1.3.2.1 yamt is 9098 1.1.1.3.2.1 yamt smaller than the target buffer. Integers that are converted to buffers 9099 1.1.1.3.2.1 yamt will 9100 1.1 jruoho not cause buffer truncation, only zero extension (both as per the ACPI 9101 1.1 jruoho spec.) The problem was introduced when code was added to truncate the 9102 1.1.1.3.2.1 yamt buffer, but this should not be performed in all cases, only the string 9103 1.1.1.3.2.1 yamt case. 9104 1.1 jruoho 9105 1.1.1.3.2.1 yamt Fixed a problem with the Buffer and Package operators where the 9106 1.1.1.3.2.1 yamt interpreter 9107 1.1 jruoho would get confused if two such operators were used as operands to an ASL 9108 1.1 jruoho operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result 9109 1.1.1.3.2.1 yamt stack was not being popped after the execution of these operators, 9110 1.1.1.3.2.1 yamt resulting 9111 1.1 jruoho in an AE_NO_RETURN_VALUE exception. 9112 1.1 jruoho 9113 1.1 jruoho Fixed a problem with constructs of the form Store(Index(...),...). The 9114 1.1.1.3.2.1 yamt reference object returned from Index was inadvertently resolved to an 9115 1.1.1.3.2.1 yamt actual 9116 1.1.1.3.2.1 yamt value. This problem was introduced in version 20050114 when the behavior 9117 1.1.1.3.2.1 yamt of 9118 1.1 jruoho Store() was modified to restrict the object types that can be used as the 9119 1.1 jruoho source operand (to match the ACPI specification.) 9120 1.1 jruoho 9121 1.1 jruoho Reduced excessive stack use within the AcpiGetObjectInfo procedure. 9122 1.1 jruoho 9123 1.1 jruoho Added a fix to aclinux.h to allow generation of AcpiExec on Linux. 9124 1.1 jruoho 9125 1.1 jruoho Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct. 9126 1.1 jruoho 9127 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9128 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9129 1.1.1.3.2.1 yamt produced 9130 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9131 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9132 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9133 1.1.1.3.2.1 yamt Note 9134 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9135 1.1.1.3.2.1 yamt and 9136 1.1 jruoho the compiler options used during generation. 9137 1.1 jruoho 9138 1.1 jruoho Previous Release: 9139 1.1 jruoho Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 9140 1.1 jruoho Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 9141 1.1 jruoho Current Release: 9142 1.1 jruoho Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total 9143 1.1 jruoho Debug Version: 164.9K Code, 69.2K Data, 234.1K Total 9144 1.1 jruoho 9145 1.1 jruoho 9146 1.1 jruoho 2) iASL Compiler/Disassembler: 9147 1.1 jruoho 9148 1.1 jruoho Fixed a code generation problem in the constant folding optimization code 9149 1.1 jruoho where incorrect code was generated if a constant was reduced to a buffer 9150 1.1 jruoho object (i.e., a reduced type 5 opcode.) 9151 1.1 jruoho 9152 1.1 jruoho Fixed a typechecking problem for the ToBuffer operator. Caused by an 9153 1.1 jruoho incorrect return type in the internal opcode information table. 9154 1.1 jruoho 9155 1.1 jruoho ---------------------------------------- 9156 1.1 jruoho 25 January 2005. Summary of changes for version 20050125: 9157 1.1 jruoho 9158 1.1 jruoho 1) ACPI CA Core Subsystem: 9159 1.1 jruoho 9160 1.1 jruoho Fixed a recently introduced problem with the Global Lock where the 9161 1.1 jruoho underlying semaphore was not created. This problem was introduced in 9162 1.1 jruoho version 20050114, and caused an AE_AML_NO_OPERAND exception during an 9163 1.1 jruoho Acquire() operation on _GL. 9164 1.1 jruoho 9165 1.1 jruoho The local object cache is now optional, and is disabled by default. Both 9166 1.1 jruoho AcpiExec and the iASL compiler enable the cache because they run in user 9167 1.1.1.3.2.1 yamt mode and this enhances their performance. #define 9168 1.1.1.3.2.1 yamt ACPI_ENABLE_OBJECT_CACHE 9169 1.1 jruoho to enable the local cache. 9170 1.1 jruoho 9171 1.1.1.3.2.1 yamt Fixed an issue in the internal function AcpiUtEvaluateObject concerning 9172 1.1.1.3.2.1 yamt the 9173 1.1.1.3.2.1 yamt optional "implicit return" support where an error was returned if no 9174 1.1.1.3.2.1 yamt return 9175 1.1.1.3.2.1 yamt object was expected, but one was implicitly returned. AE_OK is now 9176 1.1.1.3.2.1 yamt returned 9177 1.1 jruoho in this case and the implicitly returned object is deleted. 9178 1.1.1.3.2.1 yamt AcpiUtEvaluateObject is only occasionally used, and only to execute 9179 1.1.1.3.2.1 yamt reserved 9180 1.1 jruoho methods such as _STA and _INI where the return type is known up front. 9181 1.1 jruoho 9182 1.1.1.3.2.1 yamt Fixed a few issues with the internal convert-to-integer code. It now 9183 1.1.1.3.2.1 yamt returns 9184 1.1 jruoho an error if an attempt is made to convert a null string, a string of only 9185 1.1.1.3.2.1 yamt blanks/tabs, or a zero-length buffer. This affects both implicit 9186 1.1.1.3.2.1 yamt conversion 9187 1.1 jruoho and explicit conversion via the ToInteger() operator. 9188 1.1 jruoho 9189 1.1.1.3.2.1 yamt The internal debug code in AcpiUtAcquireMutex has been commented out. It 9190 1.1.1.3.2.1 yamt is 9191 1.1.1.3.2.1 yamt not needed for normal operation and should increase the performance of 9192 1.1.1.3.2.1 yamt the 9193 1.1.1.3.2.1 yamt entire subsystem. The code remains in case it is needed for debug 9194 1.1.1.3.2.1 yamt purposes 9195 1.1 jruoho again. 9196 1.1 jruoho 9197 1.1.1.3.2.1 yamt The AcpiExec source and makefile are included in the Unix/Linux package 9198 1.1.1.3.2.1 yamt for 9199 1.1 jruoho the first time. 9200 1.1 jruoho 9201 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9202 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9203 1.1.1.3.2.1 yamt produced 9204 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9205 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9206 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9207 1.1.1.3.2.1 yamt Note 9208 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9209 1.1.1.3.2.1 yamt and 9210 1.1 jruoho the compiler options used during generation. 9211 1.1 jruoho 9212 1.1 jruoho Previous Release: 9213 1.1 jruoho Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total 9214 1.1 jruoho Debug Version: 165.4K Code, 69.4K Data, 234.8K Total 9215 1.1 jruoho Current Release: 9216 1.1 jruoho Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 9217 1.1 jruoho Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 9218 1.1 jruoho 9219 1.1 jruoho 2) iASL Compiler/Disassembler: 9220 1.1 jruoho 9221 1.1.1.3.2.1 yamt Switch/Case support: A warning is now issued if the type of the Switch 9222 1.1.1.3.2.1 yamt value 9223 1.1 jruoho cannot be determined at compile time. For example, Switch(Arg0) will 9224 1.1.1.3.2.1 yamt generate the warning, and the type is assumed to be an integer. As per 9225 1.1.1.3.2.1 yamt the 9226 1.1.1.3.2.1 yamt ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate 9227 1.1.1.3.2.1 yamt the 9228 1.1 jruoho warning. 9229 1.1 jruoho 9230 1.1 jruoho Switch/Case support: Implemented support for buffer and string objects as 9231 1.1 jruoho the switch value. This is an ACPI 3.0 feature, now that LEqual supports 9232 1.1 jruoho buffers and strings. 9233 1.1 jruoho 9234 1.1.1.3.2.1 yamt Switch/Case support: The emitted code for the LEqual() comparisons now 9235 1.1.1.3.2.1 yamt uses 9236 1.1.1.3.2.1 yamt the switch value as the first operand, not the second. The case value is 9237 1.1.1.3.2.1 yamt now 9238 1.1 jruoho the second operand, and this allows the case value to be implicitly 9239 1.1 jruoho converted to the type of the switch value, not the other way around. 9240 1.1 jruoho 9241 1.1.1.3.2.1 yamt Switch/Case support: Temporary variables are now emitted immediately 9242 1.1.1.3.2.1 yamt within 9243 1.1.1.3.2.1 yamt the control method, not at the global level. This means that there are 9244 1.1.1.3.2.1 yamt now 9245 1.1.1.3.2.1 yamt 36 temps available per-method, not 36 temps per-module as was the case 9246 1.1.1.3.2.1 yamt with 9247 1.1 jruoho the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.) 9248 1.1 jruoho 9249 1.1 jruoho ---------------------------------------- 9250 1.1 jruoho 14 January 2005. Summary of changes for version 20050114: 9251 1.1 jruoho 9252 1.1 jruoho Added 2005 copyright to all module headers. This affects every module in 9253 1.1 jruoho the core subsystem, iASL compiler, and the utilities. 9254 1.1 jruoho 9255 1.1 jruoho 1) ACPI CA Core Subsystem: 9256 1.1 jruoho 9257 1.1 jruoho Fixed an issue with the String-to-Buffer conversion code where the string 9258 1.1.1.3.2.1 yamt null terminator was not included in the buffer after conversion, but 9259 1.1.1.3.2.1 yamt there 9260 1.1.1.3.2.1 yamt is existing ASL that assumes the string null terminator is included. This 9261 1.1.1.3.2.1 yamt is 9262 1.1 jruoho the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was 9263 1.1 jruoho introduced in the previous version when the code was updated to correctly 9264 1.1.1.3.2.1 yamt set the converted buffer size as per the ACPI specification. The ACPI 9265 1.1.1.3.2.1 yamt spec 9266 1.1.1.3.2.1 yamt is ambiguous and will be updated to specify that the null terminator must 9267 1.1.1.3.2.1 yamt be 9268 1.1 jruoho included in the converted buffer. This also affects the ToBuffer() ASL 9269 1.1 jruoho operator. 9270 1.1 jruoho 9271 1.1 jruoho Fixed a problem with the Mid() ASL/AML operator where it did not work 9272 1.1.1.3.2.1 yamt correctly on Buffer objects. Newly created sub-buffers were not being 9273 1.1.1.3.2.1 yamt marked 9274 1.1 jruoho as initialized. 9275 1.1 jruoho 9276 1.1 jruoho 9277 1.1 jruoho Fixed a problem in AcpiTbFindTable where incorrect string compares were 9278 1.1.1.3.2.1 yamt performed on the OemId and OemTableId table header fields. These fields 9279 1.1.1.3.2.1 yamt are 9280 1.1 jruoho not null terminated, so strncmp is now used instead of strcmp. 9281 1.1 jruoho 9282 1.1 jruoho Implemented a restriction on the Store() ASL/AML operator to align the 9283 1.1.1.3.2.1 yamt behavior with the ACPI specification. Previously, any object could be 9284 1.1.1.3.2.1 yamt used 9285 1.1.1.3.2.1 yamt as the source operand. Now, the only objects that may be used are 9286 1.1.1.3.2.1 yamt Integers, 9287 1.1 jruoho Buffers, Strings, Packages, Object References, and DDB Handles. If 9288 1.1 jruoho necessary, the original behavior can be restored by enabling the 9289 1.1 jruoho EnableInterpreterSlack flag. 9290 1.1 jruoho 9291 1.1.1.3.2.1 yamt Enhanced the optional "implicit return" support to allow an implicit 9292 1.1.1.3.2.1 yamt return 9293 1.1 jruoho value from methods that are invoked externally via the AcpiEvaluateObject 9294 1.1 jruoho interface. This enables implicit returns from the _STA and _INI methods, 9295 1.1 jruoho for example. 9296 1.1 jruoho 9297 1.1.1.3.2.1 yamt Changed the Revision() ASL/AML operator to return the current version of 9298 1.1.1.3.2.1 yamt the 9299 1.1.1.3.2.1 yamt AML interpreter, in the YYYYMMDD format.

Summary of changes for version 20041119: 9455 1.1 jruoho 9456 1.1 jruoho 1) ACPI CA Core Subsystem: 9457 1.1 jruoho 9458 1.1.1.3.2.1 yamt Fixed a problem in the internal ConvertToInteger routine where new 9459 1.1.1.3.2.1 yamt integers 9460 1.1.1.3.2.1 yamt were not truncated to 32 bits for 32-bit ACPI tables. This routine 9461 1.1.1.3.2.1 yamt converts 9462 1.1 jruoho buffers and strings to integers. 9463 1.1 jruoho 9464 1.1.1.3.2.1 yamt Implemented support to store a value to an Index() on a String object. 9465 1.1.1.3.2.1 yamt This 9466 1.1 jruoho is an ACPI 2.0 feature that had not yet been implemented. 9467 1.1 jruoho 9468 1.1.1.3.2.1 yamt Implemented new behavior for storing objects to individual package 9469 1.1.1.3.2.1 yamt elements 9470 1.1.1.3.2.1 yamt (via the Index() operator). The previous behavior was to invoke the 9471 1.1.1.3.2.1 yamt implicit 9472 1.1 jruoho conversion rules if an object was already present at the index. The new 9473 1.1.1.3.2.1 yamt behavior is to simply delete any existing object and directly store the 9474 1.1.1.3.2.1 yamt new 9475 1.1.1.3.2.1 yamt object. Although the ACPI specification seems unclear on this subject, 9476 1.1.1.3.2.1 yamt other 9477 1.1 jruoho ACPI implementations behave in this manner. (This is the root of the 9478 1.1 jruoho AE_BAD_HEX_CONSTANT issue.) 9479 1.1 jruoho 9480 1.1.1.3.2.1 yamt Modified the RSDP memory scan mechanism to support the extended checksum 9481 1.1.1.3.2.1 yamt for 9482 1.1 jruoho ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid 9483 1.1 jruoho RSDP signature is found with a valid checksum. 9484 1.1 jruoho 9485 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9486 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9487 1.1.1.3.2.1 yamt produced 9488 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9489 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9490 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9491 1.1.1.3.2.1 yamt Note 9492 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9493 1.1.1.3.2.1 yamt and 9494 1.1 jruoho the compiler options used during generation. 9495 1.1 jruoho 9496 1.1 jruoho Previous Release: 9497 1.1 jruoho Non-Debug Version: 78.5K Code, 11.5K Data, 90.0K Total 9498 1.1 jruoho Debug Version: 165.2K Code, 68.6K Data, 233.8K Total 9499 1.1 jruoho Current Release: 9500 1.1 jruoho Non-Debug Version: 78.5K Code, 11.5K Data, 90.0K Total 9501 1.1 jruoho Debug Version: 165.2K Code, 68.6K Data, 233.8K Total 9502 1.1 jruoho 9503 1.1 jruoho 9504 1.1 jruoho 2) iASL Compiler/Disassembler: 9505 1.1 jruoho 9506 1.1 jruoho Fixed a missing semicolon in the aslcompiler.y file. 9507 1.1 jruoho 9508 1.1 jruoho ---------------------------------------- 9509 1.1 jruoho 05 November 2004. Summary of changes for version 20041105: 9510 1.1 jruoho 9511 1.1 jruoho 1) ACPI CA Core Subsystem: 9512 1.1 jruoho 9513 1.1.1.3.2.1 yamt Implemented support for FADT revision 2. This was an interim table 9514 1.1.1.3.2.1 yamt (between 9515 1.1 jruoho ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register. 9516 1.1 jruoho 9517 1.1 jruoho Implemented optional support to allow uninitialized LocalX and ArgX 9518 1.1.1.3.2.1 yamt variables in a control method. The variables are initialized to an 9519 1.1.1.3.2.1 yamt Integer 9520 1.1 jruoho object with a value of zero. This support is enabled by setting the 9521 1.1 jruoho AcpiGbl_EnableInterpreterSlack flag to TRUE. 9522 1.1 jruoho 9523 1.1.1.3.2.1 yamt Implemented support for Integer objects for the SizeOf operator. Either 9524 1.1.1.3.2.1 yamt 4 9525 1.1.1.3.2.1 yamt or 8 is returned, depending on the current integer size (32-bit or 64- 9526 1.1.1.3.2.1 yamt bit, 9527 1.1 jruoho depending on the parent table revision). 9528 1.1 jruoho 9529 1.1.1.3.2.1 yamt Fixed a problem in the implementation of the SizeOf and ObjectType 9530 1.1.1.3.2.1 yamt operators 9531 1.1 jruoho where the operand was resolved to a value too early, causing incorrect 9532 1.1 jruoho return values for some objects. 9533 1.1 jruoho 9534 1.1 jruoho Fixed some possible memory leaks during exceptional conditions. 9535 1.1 jruoho 9536 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9537 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 9620 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9621 1.1.1.3.2.1 yamt Note 9622 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9623 1.1.1.3.2.1 yamt and 9624 1.1 jruoho the compiler options used during generation. 9625 1.1 jruoho 9626 1.1 jruoho Previous Release: 9627 1.1 jruoho Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total 9628 1.1 jruoho Debug Version: 164.6K Code, 68.5K Data, 233.1K Total 9629 1.1 jruoho Current Release: 9630 1.1 jruoho Non-Debug Version: 78.0K Code, 11.5K Data, 89.5K Total 9631 1.1 jruoho Debug Version: 164.8K Code, 68.6K Data, 233.4K Total 9632 1.1 jruoho 9633 1.1 jruoho 9634 1.1 jruoho 9635 1.1 jruoho 2) iASL Compiler/Disassembler: 9636 1.1 jruoho 9637 1.1 jruoho Allow the use of the ObjectType operator on uninitialized Locals and Args 9638 1.1 jruoho (returns 0 as per the ACPI specification). 9639 1.1 jruoho 9640 1.1.1.3.2.1 yamt Fixed a problem where the compiler would fault if there was a syntax 9641 1.1.1.3.2.1 yamt error 9642 1.1 jruoho in the FieldName of all of the various CreateXXXField operators. 9643 1.1 jruoho 9644 1.1.1.3.2.1 yamt Disallow the use of lower case letters within the EISAID macro, as per 9645 1.1.1.3.2.1 yamt the 9646 1.1.1.3.2.1 yamt ACPI specification. All EISAID strings must be of the form "UUUNNNN" 9647 1.1.1.3.2.1 yamt Where 9648 1.1 jruoho U is an uppercase letter and N is a hex digit. 9649 1.1 jruoho 9650 1.1 jruoho 9651 1.1 jruoho ---------------------------------------- 9652 1.1 jruoho 06 October 2004. Summary of changes for version 20041006: 9653 1.1 jruoho 9654 1.1 jruoho 1) ACPI CA Core Subsystem: 9655 1.1 jruoho 9656 1.1 jruoho Implemented support for the ACPI 3.0 Timer operator. This ASL function 9657 1.1 jruoho implements a 64-bit timer with 100 nanosecond granularity. 9658 1.1 jruoho 9659 1.1 jruoho Defined a new OSL interface, AcpiOsGetTimer. This interface is used to 9660 1.1.1.3.2.1 yamt implement the ACPI 3.0 Timer operator. This allows the host OS to 9661 1.1.1.3.2.1 yamt implement 9662 1.1.1.3.2.1 yamt the timer with the best clock available. Also, it keeps the core 9663 1.1.1.3.2.1 yamt subsystem 9664 1.1 jruoho out of the clock handling business, since the host OS (usually) performs 9665 1.1 jruoho this function. 9666 1.1 jruoho 9667 1.1 jruoho Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write) 9668 1.1 jruoho functions use a 64-bit address which is part of the packed ACPI Generic 9669 1.1.1.3.2.1 yamt Address Structure. Since the structure is non-aligned, the alignment 9670 1.1.1.3.2.1 yamt macros 9671 1.1 jruoho are now used to extract the address to a local variable before use. 9672 1.1 jruoho 9673 1.1.1.3.2.1 yamt Fixed a problem where the ToInteger operator assumed all input strings 9674 1.1.1.3.2.1 yamt were 9675 1.1.1.3.2.1 yamt hexadecimal. The operator now handles both decimal strings and hex 9676 1.1.1.3.2.1 yamt strings 9677 1.1 jruoho (prefixed with "0x"). 9678 1.1 jruoho 9679 1.1 jruoho Fixed a problem where the string length in the string object created as a 9680 1.1 jruoho result of the internal ConvertToString procedure could be incorrect. This 9681 1.1.1.3.2.1 yamt potentially affected all implicit conversions and also the 9682 1.1.1.3.2.1 yamt ToDecimalString 9683 1.1 jruoho and ToHexString operators. 9684 1.1 jruoho 9685 1.1 jruoho Fixed two problems in the ToString operator. If the length parameter was 9686 1.1 jruoho zero, an incorrect string object was created and the value of the input 9687 1.1 jruoho length parameter was inadvertently changed from zero to Ones. 9688 1.1 jruoho 9689 1.1.1.3.2.1 yamt Fixed a problem where the optional ResourceSource string in the 9690 1.1.1.3.2.1 yamt ExtendedIRQ 9691 1.1 jruoho resource macro was ignored. 9692 1.1 jruoho 9693 1.1.1.3.2.1 yamt Simplified the interfaces to the internal division functions, reducing 9694 1.1.1.3.2.1 yamt code 9695 1.1 jruoho size and complexity. 9696 1.1 jruoho 9697 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9698 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9699 1.1.1.3.2.1 yamt produced 9700 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9701 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9702 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9703 1.1.1.3.2.1 yamt Note 9704 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9705 1.1.1.3.2.1 yamt and 9706 1.1 jruoho the compiler options used during generation. 9707 1.1 jruoho 9708 1.1 jruoho Previous Release: 9709 1.1 jruoho Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total 9710 1.1 jruoho Debug Version: 164.5K Code, 68.3K Data, 232.8K Total 9711 1.1 jruoho Current Release: 9712 1.1 jruoho Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total 9713 1.1 jruoho Debug Version: 164.6K Code, 68.5K Data, 233.1K Total 9714 1.1 jruoho 9715 1.1 jruoho 9716 1.1 jruoho 2) iASL Compiler/Disassembler: 9717 1.1 jruoho 9718 1.1 jruoho Implemented support for the ACPI 3.0 Timer operator. 9719 1.1 jruoho 9720 1.1.1.3.2.1 yamt Fixed a problem where the Default() operator was inadvertently ignored in 9721 1.1.1.3.2.1 yamt a 9722 1.1 jruoho Switch/Case block. This was a problem in the translation of the Switch 9723 1.1 jruoho statement to If...Else pairs. 9724 1.1 jruoho 9725 1.1.1.3.2.1 yamt Added support to allow a standalone Return operator, with no parentheses 9726 1.1.1.3.2.1 yamt (or 9727 1.1 jruoho operands). 9728 1.1 jruoho 9729 1.1 jruoho Fixed a problem with code generation for the ElseIf operator where the 9730 1.1 jruoho translated Else...If parse tree was improperly constructed leading to the 9731 1.1 jruoho loss of some code. 9732 1.1 jruoho 9733 1.1 jruoho ---------------------------------------- 9734 1.1 jruoho 22 September 2004. Summary of changes for version 20040922: 9735 1.1 jruoho 9736 1.1 jruoho 1) ACPI CA Core Subsystem: 9737 1.1 jruoho 9738 1.1.1.3.2.1 yamt Fixed a problem with the implementation of the LNot() operator where 9739 1.1.1.3.2.1 yamt "Ones" 9740 1.1.1.3.2.1 yamt was not returned for the TRUE case. Changed the code to return Ones 9741 1.1.1.3.2.1 yamt instead 9742 1.1.1.3.2.1 yamt of (!Arg) which was usually 1. This change affects iASL constant folding 9743 1.1.1.3.2.1 yamt for 9744 1.1 jruoho this operator also. 9745 1.1 jruoho 9746 1.1.1.3.2.1 yamt Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was 9747 1.1.1.3.2.1 yamt not 9748 1.1 jruoho initialized properly -- Now zero the entire buffer in this case where the 9749 1.1 jruoho buffer already exists. 9750 1.1 jruoho 9751 1.1 jruoho Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32 9752 1.1 jruoho Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all 9753 1.1 jruoho related code considerably. This will require changes/updates to all OS 9754 1.1 jruoho interface layers (OSLs.) 9755 1.1 jruoho 9756 1.1.1.3.2.1 yamt Implemented a new external interface, AcpiInstallExceptionHandler, to 9757 1.1.1.3.2.1 yamt allow 9758 1.1.1.3.2.1 yamt a system exception handler to be installed. This handler is invoked upon 9759 1.1.1.3.2.1 yamt any 9760 1.1 jruoho run-time exception that occurs during control method execution. 9761 1.1 jruoho 9762 1.1 jruoho Added support for the DSDT in AcpiTbFindTable. This allows the 9763 1.1 jruoho DataTableRegion() operator to access the local copy of the DSDT. 9764 1.1 jruoho 9765 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9766 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9767 1.1.1.3.2.1 yamt produced 9768 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9769 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9770 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9771 1.1.1.3.2.1 yamt Note 9772 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9773 1.1.1.3.2.1 yamt and 9774 1.1 jruoho the compiler options used during generation. 9775 1.1 jruoho 9776 1.1 jruoho Previous Release: 9777 1.1 jruoho Non-Debug Version: 77.8K Code, 11.4K Data, 89.2K Total 9778 1.1 jruoho Debug Version: 164.2K Code, 68.2K Data, 232.4K Total 9779 1.1 jruoho Current Release: 9780 1.1 jruoho Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total 9781 1.1 jruoho Debug Version: 164.5K Code, 68.3K Data, 232.8K Total 9782 1.1 jruoho 9783 1.1 jruoho 9784 1.1 jruoho 2) iASL Compiler/Disassembler: 9785 1.1 jruoho 9786 1.1 jruoho Fixed a problem with constant folding and the LNot operator. LNot was 9787 1.1.1.3.2.1 yamt returning 1 in the TRUE case, not Ones as per the ACPI specification. 9788 1.1.1.3.2.1 yamt This 9789 1.1 jruoho could result in the generation of an incorrect folded/reduced constant. 9790 1.1 jruoho 9791 1.1 jruoho End-Of-File is now allowed within a "//"-style comment. A parse error no 9792 1.1.1.3.2.1 yamt longer occurs if such a comment is at the very end of the input ASL 9793 1.1.1.3.2.1 yamt source 9794 1.1 jruoho file. 9795 1.1 jruoho 9796 1.1 jruoho Implemented the "-r" option to override the Revision in the table header. 9797 1.1.1.3.2.1 yamt The initial use of this option will be to simplify the evaluation of the 9798 1.1.1.3.2.1 yamt AML 9799 1.1.1.3.2.1 yamt interpreter by allowing a single ASL source module to be compiled for 9800 1.1.1.3.2.1 yamt either 9801 1.1 jruoho 32-bit or 64-bit integers. 9802 1.1 jruoho 9803 1.1 jruoho 9804 1.1 jruoho ---------------------------------------- 9805 1.1 jruoho 27 August 2004. Summary of changes for version 20040827: 9806 1.1 jruoho 9807 1.1 jruoho 1) ACPI CA Core Subsystem: 9808 1.1 jruoho 9809 1.1 jruoho - Implemented support for implicit object conversion in the non-numeric 9810 1.1.1.3.2.1 yamt logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, 9811 1.1.1.3.2.1 yamt and 9812 1.1 jruoho LNotEqual.) Any combination of Integers/Strings/Buffers may now be used; 9813 1.1.1.3.2.1 yamt the second operand is implicitly converted on the fly to match the type 9814 1.1.1.3.2.1 yamt of 9815 1.1 jruoho the first operand. For example: 9816 1.1 jruoho 9817 1.1 jruoho LEqual (Source1, Source2) 9818 1.1 jruoho 9819 1.1.1.3.2.1 yamt Source1 and Source2 must each evaluate to an integer, a string, or a 9820 1.1.1.3.2.1 yamt buffer. 9821 1.1.1.3.2.1 yamt The data type of Source1 dictates the required type of Source2. Source2 9822 1.1.1.3.2.1 yamt is 9823 1.1 jruoho implicitly converted if necessary to match the type of Source1. 9824 1.1 jruoho 9825 1.1.1.3.2.1 yamt - Updated and corrected the behavior of the string conversion support. 9826 1.1.1.3.2.1 yamt The 9827 1.1 jruoho rules concerning conversion of buffers to strings (according to the ACPI 9828 1.1 jruoho specification) are as follows: 9829 1.1 jruoho 9830 1.1 jruoho ToDecimalString - explicit byte-wise conversion of buffer to string of 9831 1.1.1.3.2.1 yamt decimal values (0-255) separated by commas. ToHexString - explicit byte- 9832 1.1.1.3.2.1 yamt wise 9833 1.1 jruoho conversion of buffer to string of hex values (0-FF) separated by commas. 9834 1.1.1.3.2.1 yamt ToString - explicit byte-wise conversion of buffer to string. Byte-by- 9835 1.1.1.3.2.1 yamt byte 9836 1.1.1.3.2.1 yamt copy with no transform except NULL terminated. Any other implicit buffer- 9837 1.1.1.3.2.1 yamt to- 9838 1.1.1.3.2.1 yamt string conversion - byte-wise conversion of buffer to string of hex 9839 1.1.1.3.2.1 yamt values 9840 1.1 jruoho (0-FF) separated by spaces. 9841 1.1 jruoho 9842 1.1 jruoho - Fixed typo in definition of AcpiGbl_EnableInterpreterSlack. 9843 1.1 jruoho 9844 1.1.1.3.2.1 yamt - Fixed a problem in AcpiNsGetPathnameLength where the returned length 9845 1.1.1.3.2.1 yamt was 9846 1.1 jruoho one byte too short in the case of a node in the root scope. This could 9847 1.1 jruoho cause a fault during debug output. 9848 1.1 jruoho 9849 1.1.1.3.2.1 yamt - Code and Data Size: Current and previous core subsystem library sizes 9850 1.1.1.3.2.1 yamt are 9851 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9852 1.1.1.3.2.1 yamt produced 9853 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9854 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 9855 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 9856 1.1.1.3.2.1 yamt Note 9857 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 9858 1.1.1.3.2.1 yamt and 9859 1.1 jruoho the compiler options used during generation. 9860 1.1 jruoho 9861 1.1 jruoho Previous Release: 9862 1.1 jruoho Non-Debug Version: 77.9K Code, 11.5K Data, 89.4K Total 9863 1.1 jruoho Debug Version: 164.1K Code, 68.3K Data, 232.4K Total 9864 1.1 jruoho Current Release: 9865 1.1 jruoho Non-Debug Version: 77.8K Code, 11.4K Data, 89.2K Total 9866 1.1 jruoho Debug Version: 164.2K Code, 68.2K Data, 232.4K Total 9867 1.1 jruoho 9868 1.1 jruoho 9869 1.1 jruoho 2) iASL Compiler/Disassembler: 9870 1.1 jruoho 9871 1.1 jruoho - Fixed a Linux generation error. 9872 1.1 jruoho 9873 1.1 jruoho 9874 1.1 jruoho ---------------------------------------- 9875 1.1 jruoho 16 August 2004.

This support returns the result of the last 9881 1.1.1.3.2.1 yamt ASL 9882 1.1 jruoho operation within a control method, in the absence of an explicit Return() 9883 1.1 jruoho operator. A few machines depend on this behavior, even though it is not 9884 1.1.1.3.2.1 yamt explicitly supported by the ASL language. It is optional support that 9885 1.1.1.3.2.1 yamt can 9886 1.1 jruoho be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag. 9887 1.1 jruoho 9888 1.1.1.3.2.1 yamt Removed support for the PCI_Config address space from the internal low 9889 1.1.1.3.2.1 yamt level 9890 1.1 jruoho hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite). This 9891 1.1.1.3.2.1 yamt support was not used internally, and would not work correctly anyway 9892 1.1.1.3.2.1 yamt because 9893 1.1 jruoho the PCI bus number and segment number were not supported. There are 9894 1.1.1.3.2.1 yamt separate interfaces for PCI configuration space access because of the 9895 1.1.1.3.2.1 yamt unique 9896 1.1 jruoho interface. 9897 1.1 jruoho 9898 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 9899 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 9900 1.1.1.3.2.1 yamt produced 9901 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 9902 1.1 jruoho any ACPI driver or OSPM code.

This applies when using the -g or - 10061 1.1 jruoho d<nofilename> options. The compiler now looks for both strings as 10062 1.1 jruoho necessary. 10063 1.1 jruoho 10064 1.1.1.3.2.1 yamt Fixed a problem with compiler namepath optimization where a namepath 10065 1.1.1.3.2.1 yamt within 10066 1.1.1.3.2.1 yamt the Scope() operator could not be optimized if the namepath was a subpath 10067 1.1.1.3.2.1 yamt of 10068 1.1 jruoho the current scope path. 10069 1.1 jruoho 10070 1.1 jruoho ---------------------------------------- 10071 1.1 jruoho 27 May 2004. Summary of changes for version 20040527: 10072 1.1 jruoho 10073 1.1 jruoho 1) ACPI CA Core Subsystem: 10074 1.1 jruoho 10075 1.1.1.3.2.1 yamt Completed a new design and implementation for EBDA (Extended BIOS Data 10076 1.1.1.3.2.1 yamt Area) 10077 1.1.1.3.2.1 yamt support in the RSDP scan code. The original code improperly scanned for 10078 1.1.1.3.2.1 yamt the 10079 1.1.1.3.2.1 yamt EBDA by simply scanning from memory location 0 to 0x400. The correct 10080 1.1.1.3.2.1 yamt method 10081 1.1 jruoho is to first obtain the EBDA pointer from within the BIOS data area, then 10082 1.1.1.3.2.1 yamt scan 1K of memory starting at the EBDA pointer. There appear to be few 10083 1.1.1.3.2.1 yamt if 10084 1.1 jruoho any machines that place the RSDP in the EBDA, however. 10085 1.1 jruoho 10086 1.1 jruoho Integrated a fix for a possible fault during evaluation of BufferField 10087 1.1 jruoho arguments. Obsolete code that was causing the problem was removed. 10088 1.1 jruoho 10089 1.1 jruoho Found and fixed a problem in the Field Support Code where data could be 10090 1.1 jruoho corrupted on a bit field read that starts on an aligned boundary but does 10091 1.1 jruoho not end on an aligned boundary. Merged the read/write "datum length" 10092 1.1 jruoho calculation code into a common procedure. 10093 1.1 jruoho 10094 1.1 jruoho Rolled in a couple of changes to the FreeBSD-specific header. 10095 1.1 jruoho 10096 1.1 jruoho 10097 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10098 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 10102 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 10103 1.1.1.3.2.1 yamt Note 10104 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 10105 1.1.1.3.2.1 yamt and 10106 1.1 jruoho the compiler options used during generation. 10107 1.1 jruoho 10108 1.1 jruoho Previous Release: 10109 1.1 jruoho Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 10110 1.1 jruoho Debug Version: 163.2K Code, 67.2K Data, 230.4K Total 10111 1.1 jruoho Current Release: 10112 1.1 jruoho Non-Debug Version: 77.7K Code, 11.5K Data, 89.2K Total 10113 1.1 jruoho Debug Version: 163.3K Code, 67.2K Data, 230.5K Total 10114 1.1 jruoho 10115 1.1 jruoho 10116 1.1 jruoho 2) iASL Compiler/Disassembler: 10117 1.1 jruoho 10118 1.1.1.3.2.1 yamt Fixed a generation warning produced by some overly-verbose compilers for 10119 1.1.1.3.2.1 yamt a 10120 1.1 jruoho 64-bit constant. 10121 1.1 jruoho 10122 1.1 jruoho ---------------------------------------- 10123 1.1 jruoho 14 May 2004. Summary of changes for version 20040514: 10124 1.1 jruoho 10125 1.1 jruoho 1) ACPI CA Core Subsystem: 10126 1.1 jruoho 10127 1.1 jruoho Fixed a problem where hardware GPE enable bits sometimes not set properly 10128 1.1 jruoho during and after GPE method execution. Result of 04/27 changes. 10129 1.1 jruoho 10130 1.1 jruoho Removed extra "clear all GPEs" when sleeping/waking. 10131 1.1 jruoho 10132 1.1 jruoho Removed AcpiHwEnableGpe and AcpiHwDisableGpe, replaced by the single 10133 1.1.1.3.2.1 yamt AcpiHwWriteGpeEnableReg. Changed a couple of calls to the functions above 10134 1.1.1.3.2.1 yamt to 10135 1.1 jruoho the new AcpiEv* calls as appropriate. 10136 1.1 jruoho 10137 1.1.1.3.2.1 yamt ACPI_OS_NAME was removed from the OS-specific headers. The default name 10138 1.1.1.3.2.1 yamt is 10139 1.1.1.3.2.1 yamt now "Microsoft Windows NT" for maximum compatibility. However this can 10140 1.1.1.3.2.1 yamt be 10141 1.1 jruoho changed by modifying the acconfig.h file. 10142 1.1 jruoho 10143 1.1 jruoho Allow a single invocation of AcpiInstallNotifyHandler for a handler that 10144 1.1 jruoho traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag. 10145 1.1 jruoho 10146 1.1 jruoho Run _INI methods on ThermalZone objects. This is against the ACPI 10147 1.1.1.3.2.1 yamt specification, but there is apparently ASL code in the field that has 10148 1.1.1.3.2.1 yamt these 10149 1.1 jruoho _INI methods, and apparently "other" AML interpreters execute them. 10150 1.1 jruoho 10151 1.1 jruoho Performed a full 16/32/64 bit lint that resulted in some small changes. 10152 1.1 jruoho 10153 1.1 jruoho Added a sleep simulation command to the AML debugger to test sleep code. 10154 1.1 jruoho 10155 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10156 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 10160 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 10161 1.1.1.3.2.1 yamt Note 10162 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 10163 1.1.1.3.2.1 yamt and 10164 1.1 jruoho the compiler options used during generation. 10165 1.1 jruoho 10166 1.1 jruoho Previous Release: 10167 1.1 jruoho Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 10168 1.1 jruoho Debug Version: 162.9K Code, 67.0K Data, 229.9K Total 10169 1.1 jruoho Current Release: 10170 1.1 jruoho Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 10171 1.1 jruoho Debug Version: 163.2K Code, 67.2K Data, 230.4K Total 10172 1.1 jruoho 10173 1.1 jruoho ---------------------------------------- 10174 1.1 jruoho 27 April 2004. Summary of changes for version 20040427: 10175 1.1 jruoho 10176 1.1 jruoho 1) ACPI CA Core Subsystem: 10177 1.1 jruoho 10178 1.1 jruoho Completed a major overhaul of the GPE handling within ACPI CA. There are 10179 1.1.1.3.2.1 yamt now three types of GPEs: wake-only, runtime-only, and combination 10180 1.1.1.3.2.1 yamt wake/run. 10181 1.1 jruoho The only GPEs allowed to be combination wake/run are for button-style 10182 1.1.1.3.2.1 yamt devices such as a control-method power button, control-method sleep 10183 1.1.1.3.2.1 yamt button, 10184 1.1.1.3.2.1 yamt or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are 10185 1.1.1.3.2.1 yamt not 10186 1.1 jruoho referenced by any _PRW methods are marked for "runtime" and hardware 10187 1.1.1.3.2.1 yamt enabled. Any GPE that is referenced by a _PRW method is marked for 10188 1.1.1.3.2.1 yamt "wake" 10189 1.1 jruoho (and disabled at runtime). However, at sleep time, only those GPEs that 10190 1.1.1.3.2.1 yamt have been specifically enabled for wake via the AcpiEnableGpe interface 10191 1.1.1.3.2.1 yamt will 10192 1.1 jruoho actually be hardware enabled. 10193 1.1 jruoho 10194 1.1.1.3.2.1 yamt A new external interface has been added, AcpiSetGpeType(), that is meant 10195 1.1.1.3.2.1 yamt to 10196 1.1.1.3.2.1 yamt be used by device drivers to force a GPE to a particular type. It will 10197 1.1.1.3.2.1 yamt be 10198 1.1 jruoho especially useful for the drivers for the button devices mentioned above. 10199 1.1 jruoho 10200 1.1 jruoho Completed restructuring of the ACPI CA initialization sequence so that 10201 1.1.1.3.2.1 yamt default operation region handlers are installed before GPEs are 10202 1.1.1.3.2.1 yamt initialized 10203 1.1.1.3.2.1 yamt and the _PRW methods are executed. This will prevent errors when the 10204 1.1.1.3.2.1 yamt _PRW 10205 1.1 jruoho methods attempt to access system memory or I/O space. 10206 1.1 jruoho 10207 1.1.1.3.2.1 yamt GPE enable/disable no longer reads the GPE enable register. We now keep 10208 1.1.1.3.2.1 yamt the 10209 1.1 jruoho enable info for runtime and wake separate and in the GPE_EVENT_INFO. We 10210 1.1 jruoho thus no longer depend on the hardware to maintain these bits. 10211 1.1 jruoho 10212 1.1 jruoho Always clear the wake status and fixed/GPE status bits before sleep, even 10213 1.1 jruoho for state S5. 10214 1.1 jruoho 10215 1.1 jruoho Improved the AML debugger output for displaying the GPE blocks and their 10216 1.1 jruoho current status. 10217 1.1 jruoho 10218 1.1.1.3.2.1 yamt Added new strings for the _OSI method, of the form "Windows 2001 SPx" 10219 1.1.1.3.2.1 yamt where 10220 1.1 jruoho x = 0,1,2,3,4. 10221 1.1 jruoho 10222 1.1.1.3.2.1 yamt Fixed a problem where the physical address was incorrectly calculated 10223 1.1.1.3.2.1 yamt when 10224 1.1.1.3.2.1 yamt the Load() operator was used to directly load from an Operation Region 10225 1.1.1.3.2.1 yamt (vs. 10226 1.1.1.3.2.1 yamt loading from a Field object.) Also added check for minimum table length 10227 1.1.1.3.2.1 yamt for 10228 1.1 jruoho this case. 10229 1.1 jruoho 10230 1.1 jruoho Fix for multiple mutex acquisition. Restore original thread SyncLevel on 10231 1.1 jruoho mutex release. 10232 1.1 jruoho 10233 1.1 jruoho Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for 10234 1.1 jruoho consistency with the other fields returned. 10235 1.1 jruoho 10236 1.1 jruoho Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such 10237 1.1 jruoho structure for each GPE in the system, so the size of this structure is 10238 1.1 jruoho important. 10239 1.1 jruoho 10240 1.1.1.3.2.1 yamt CPU stack requirement reduction: Cleaned up the method execution and 10241 1.1.1.3.2.1 yamt object 10242 1.1 jruoho evaluation paths so that now a parameter structure is passed, instead of 10243 1.1 jruoho copying the various method parameters over and over again. 10244 1.1 jruoho 10245 1.1 jruoho In evregion.c: Correctly exit and reenter the interpreter region if and 10246 1.1.1.3.2.1 yamt only if dispatching an operation region request to a user-installed 10247 1.1.1.3.2.1 yamt handler. 10248 1.1 jruoho Do not exit/reenter when dispatching to a default handler (e.g., default 10249 1.1 jruoho system memory or I/O handlers) 10250 1.1 jruoho 10251 1.1 jruoho 10252 1.1.1.3.2.1 yamt Notes for updating drivers for the new GPE support. The following 10253 1.1.1.3.2.1 yamt changes 10254 1.1.1.3.2.1 yamt must be made to ACPI-related device drivers that are attached to one or 10255 1.1.1.3.2.1 yamt more 10256 1.1.1.3.2.1 yamt GPEs: (This information will be added to the ACPI CA Programmer 10257 1.1.1.3.2.1 yamt Reference.) 10258 1.1 jruoho 10259 1.1.1.3.2.1 yamt 1) AcpiInstallGpeHandler no longer automatically enables the GPE, you 10260 1.1.1.3.2.1 yamt must 10261 1.1 jruoho explicitly call AcpiEnableGpe. 10262 1.1 jruoho 2) There is a new interface called AcpiSetGpeType. This should be called 10263 1.1 jruoho before enabling the GPE. Also, this interface will automatically disable 10264 1.1 jruoho the GPE if it is currently enabled. 10265 1.1 jruoho 3) AcpiEnableGpe no longer supports a GPE type flag. 10266 1.1 jruoho 10267 1.1 jruoho Specific drivers that must be changed: 10268 1.1 jruoho 1) EC driver: 10269 1.1 jruoho AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED, 10270 1.1 jruoho AeGpeHandler, NULL); 10271 1.1 jruoho AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME); 10272 1.1 jruoho AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR); 10273 1.1 jruoho 10274 1.1 jruoho 2) Button Drivers (Power, Lid, Sleep): 10275 1.1 jruoho Run _PRW method under parent device 10276 1.1 jruoho If _PRW exists: /* This is a control-method button */ 10277 1.1 jruoho Extract GPE number and possibly GpeDevice 10278 1.1 jruoho AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN); 10279 1.1 jruoho AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR); 10280 1.1 jruoho 10281 1.1.1.3.2.1 yamt For all other devices that have _PRWs, we automatically set the GPE type 10282 1.1.1.3.2.1 yamt to 10283 1.1.1.3.2.1 yamt ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled. 10284 1.1.1.3.2.1 yamt This 10285 1.1.1.3.2.1 yamt must be done on a selective basis, usually requiring some kind of user 10286 1.1.1.3.2.1 yamt app 10287 1.1 jruoho to allow the user to pick the wake devices. 10288 1.1 jruoho 10289 1.1 jruoho 10290 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10291 1.1.1.3.2.1 yamt shown below.

Summary of changes for version 20040402: 10313 1.1 jruoho 10314 1.1 jruoho 1) ACPI CA Core Subsystem: 10315 1.1 jruoho 10316 1.1 jruoho Fixed an interpreter problem where an indirect store through an ArgX 10317 1.1 jruoho parameter was incorrectly applying the "implicit conversion rules" during 10318 1.1.1.3.2.1 yamt the store. From the ACPI specification: "If the target is a method local 10319 1.1.1.3.2.1 yamt or 10320 1.1 jruoho argument (LocalX or ArgX), no conversion is performed and the result is 10321 1.1 jruoho stored directly to the target". The new behavior is to disable implicit 10322 1.1 jruoho conversion during ALL stores to an ArgX. 10323 1.1 jruoho 10324 1.1 jruoho Changed the behavior of the _PRW method scan to ignore any and all errors 10325 1.1 jruoho returned by a given _PRW. This prevents the scan from aborting from the 10326 1.1 jruoho failure of any single _PRW. 10327 1.1 jruoho 10328 1.1.1.3.2.1 yamt Moved the runtime configuration parameters from the global init procedure 10329 1.1.1.3.2.1 yamt to 10330 1.1 jruoho static variables in acglobal.h. This will allow the host to override the 10331 1.1 jruoho default values easily. 10332 1.1 jruoho 10333 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10334 1.1.1.3.2.1 yamt shown below.

The debug version of the code includes the 10338 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 10339 1.1.1.3.2.1 yamt Note 10340 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 10341 1.1.1.3.2.1 yamt and 10342 1.1 jruoho the compiler options used during generation. 10343 1.1 jruoho 10344 1.1 jruoho Previous Release: 10345 1.1 jruoho Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total 10346 1.1 jruoho Debug Version: 160.8K Code, 66.1K Data, 226.9K Total 10347 1.1 jruoho Current Release: 10348 1.1 jruoho Non-Debug Version: 77.0K Code, 11.4K Data, 88.4K Total 10349 1.1 jruoho Debug Version: 161.0K Code, 66.3K Data, 227.3K Total 10350 1.1 jruoho 10351 1.1 jruoho 10352 1.1 jruoho 2) iASL Compiler/Disassembler: 10353 1.1 jruoho 10354 1.1.1.3.2.1 yamt iASL now fully disassembles SSDTs. However, External() statements are 10355 1.1.1.3.2.1 yamt not 10356 1.1 jruoho generated automatically for unresolved symbols at this time. This is a 10357 1.1 jruoho planned feature for future implementation. 10358 1.1 jruoho 10359 1.1.1.3.2.1 yamt Fixed a scoping problem in the disassembler that occurs when the type of 10360 1.1.1.3.2.1 yamt the 10361 1.1 jruoho target of a Scope() operator is overridden. This problem caused an 10362 1.1 jruoho incorrectly nested internal namespace to be constructed. 10363 1.1 jruoho 10364 1.1.1.3.2.1 yamt Any warnings or errors that are emitted during disassembly are now 10365 1.1.1.3.2.1 yamt commented 10366 1.1.1.3.2.1 yamt out automatically so that the resulting file can be recompiled without 10367 1.1.1.3.2.1 yamt any 10368 1.1 jruoho hand editing. 10369 1.1 jruoho 10370 1.1 jruoho ---------------------------------------- 10371 1.1 jruoho 26 March 2004. Summary of changes for version 20040326: 10372 1.1 jruoho 10373 1.1 jruoho 1) ACPI CA Core Subsystem: 10374 1.1 jruoho 10375 1.1 jruoho Implemented support for "wake" GPEs via interaction between GPEs and the 10376 1.1 jruoho _PRW methods. Every GPE that is pointed to by one or more _PRWs is 10377 1.1 jruoho identified as a WAKE GPE and by default will no longer be enabled at 10378 1.1.1.3.2.1 yamt runtime. Previously, we were blindly enabling all GPEs with a 10379 1.1.1.3.2.1 yamt corresponding 10380 1.1.1.3.2.1 yamt _Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway. 10381 1.1.1.3.2.1 yamt We 10382 1.1 jruoho believe this has been the cause of thousands of "spurious" GPEs on some 10383 1.1 jruoho systems. 10384 1.1 jruoho 10385 1.1 jruoho This new GPE behavior is can be reverted to the original behavior (enable 10386 1.1 jruoho ALL GPEs at runtime) via a runtime flag. 10387 1.1 jruoho 10388 1.1 jruoho Fixed a problem where aliased control methods could not access objects 10389 1.1 jruoho properly. The proper scope within the namespace was not initialized 10390 1.1 jruoho (transferred to the target of the aliased method) before executing the 10391 1.1 jruoho target method. 10392 1.1 jruoho 10393 1.1.1.3.2.1 yamt Fixed a potential race condition on internal object deletion on the 10394 1.1.1.3.2.1 yamt return 10395 1.1 jruoho object in AcpiEvaluateObject. 10396 1.1 jruoho 10397 1.1 jruoho Integrated a fix for resource descriptors where both _MEM and _MTP were 10398 1.1 jruoho being extracted instead of just _MEM. (i.e. bitmask was incorrectly too 10399 1.1 jruoho wide, 0x0F instead of 0x03.) 10400 1.1 jruoho 10401 1.1.1.3.2.1 yamt Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, 10402 1.1.1.3.2.1 yamt preventing 10403 1.1.1.3.2.1 yamt a 10404 1.1 jruoho fault in some cases. 10405 1.1 jruoho 10406 1.1 jruoho Updated Notify() values for debug statements in evmisc.c 10407 1.1 jruoho 10408 1.1 jruoho Return proper status from AcpiUtMutexInitialize, not just simply AE_OK. 10409 1.1 jruoho 10410 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10411 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 10412 1.1.1.3.2.1 yamt produced 10413 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 10414 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 10415 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 10416 1.1.1.3.2.1 yamt Note 10417 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 10418 1.1.1.3.2.1 yamt and 10419 1.1 jruoho the compiler options used during generation. 10420 1.1 jruoho 10421 1.1 jruoho Previous Release: 10422 1.1 jruoho 10423 1.1 jruoho Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total 10424 1.1 jruoho Debug Version: 160.3K Code, 66.0K Data, 226.3K Total 10425 1.1 jruoho Current Release: 10426 1.1 jruoho Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total 10427 1.1 jruoho Debug Version: 160.8K Code, 66.1K Data, 226.9K Total 10428 1.1 jruoho 10429 1.1 jruoho ---------------------------------------- 10430 1.1 jruoho 11 March 2004. Summary of changes for version 20040311: 10431 1.1 jruoho 10432 1.1 jruoho 1) ACPI CA Core Subsystem: 10433 1.1 jruoho 10434 1.1 jruoho Fixed a problem where errors occurring during the parse phase of control 10435 1.1 jruoho method execution did not abort cleanly. For example, objects created and 10436 1.1 jruoho installed in the namespace were not deleted. This caused all subsequent 10437 1.1 jruoho invocations of the method to return the AE_ALREADY_EXISTS exception. 10438 1.1 jruoho 10439 1.1.1.3.2.1 yamt Implemented a mechanism to force a control method to "Serialized" 10440 1.1.1.3.2.1 yamt execution 10441 1.1 jruoho if the method attempts to create namespace objects. (The root of the 10442 1.1 jruoho AE_ALREADY_EXISTS problem.) 10443 1.1 jruoho 10444 1.1 jruoho Implemented support for the predefined _OSI "internal" control method. 10445 1.1.1.3.2.1 yamt Initial supported strings are "Linux", "Windows 2000", "Windows 2001", 10446 1.1.1.3.2.1 yamt and 10447 1.1.1.3.2.1 yamt "Windows 2001.1", and can be easily upgraded for new strings as 10448 1.1.1.3.2.1 yamt necessary. 10449 1.1 jruoho This feature will allow "other" operating systems to execute the fully 10450 1.1 jruoho tested, "Windows" code path through the ASL code 10451 1.1 jruoho 10452 1.1 jruoho Global Lock Support: Now allows multiple acquires and releases with any 10453 1.1.1.3.2.1 yamt internal thread. Removed concept of "owning thread" for this special 10454 1.1.1.3.2.1 yamt mutex. 10455 1.1 jruoho 10456 1.1.1.3.2.1 yamt Fixed two functions that were inappropriately declaring large objects on 10457 1.1.1.3.2.1 yamt the 10458 1.1.1.3.2.1 yamt CPU stack: PsParseLoop, NsEvaluateRelative. Reduces the stack usage 10459 1.1.1.3.2.1 yamt during 10460 1.1 jruoho method execution considerably. 10461 1.1 jruoho 10462 1.1 jruoho Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the 10463 1.1 jruoho S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT. 10464 1.1 jruoho 10465 1.1 jruoho Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs 10466 1.1 jruoho defined on the machine. 10467 1.1 jruoho 10468 1.1.1.3.2.1 yamt Implemented two runtime options: One to force all control method 10469 1.1.1.3.2.1 yamt execution 10470 1.1.1.3.2.1 yamt to "Serialized" to mimic Windows behavior, another to disable _OSI 10471 1.1.1.3.2.1 yamt support 10472 1.1 jruoho if it causes problems on a given machine. 10473 1.1 jruoho 10474 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 10475 1.1.1.3.2.1 yamt shown below. These are the code and data sizes for the acpica.lib 10476 1.1.1.3.2.1 yamt produced 10477 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 10478 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 10479 1.1.1.3.2.1 yamt debug output trace mechanism and has a much larger code and data size. 10480 1.1.1.3.2.1 yamt Note 10481 1.1.1.3.2.1 yamt that these values will vary depending on the efficiency of the compiler 10482 1.1.1.3.2.1 yamt and 10483 1.1 jruoho the compiler options used during generation. 10484 1.1 jruoho 10485 1.1 jruoho Previous Release: 10486 1.1 jruoho Non-Debug Version: 74.8K Code, 10.1K Data, 84.9K Total 10487 1.1 jruoho Debug Version: 158.7K Code, 65.1K Data, 223.8K Total 10488 1.1 jruoho Current Release: 10489 1.1 jruoho Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total 10490 1.1 jruoho Debug Version: 160.3K Code, 66.0K Data, 226.3K Total 10491 1.1 jruoho 10492 1.1 jruoho 2) iASL Compiler/Disassembler: 10493 1.1 jruoho 10494 1.1 jruoho Fixed an array size problem for FreeBSD that would cause the compiler to 10495 1.1 jruoho fault. 10496 1.1 jruoho 10497 1.1 jruoho ---------------------------------------- 10498 1.1 jruoho 20 February 2004. Summary of changes for version 20040220: 10499 1.1 jruoho 10500 1.1 jruoho 10501 1.1 jruoho 1) ACPI CA Core Subsystem: 10502 1.1 jruoho 10503 1.1 jruoho Implemented execution of _SxD methods for Device objects in the 10504 1.1 jruoho GetObjectInfo interface. 10505 1.1 jruoho 10506 1.1 jruoho Fixed calls to _SST method to pass the correct arguments. 10507 1.1 jruoho 10508 1.1 jruoho Added a call to _SST on wake to restore to "working" state. 10509 1.1 jruoho 10510 1.1 jruoho Check for End-Of-Buffer failure case in the WalkResources interface. 10511 1.1 jruoho 10512 1.1 jruoho Integrated fix for 64-bit alignment issue in acglobal.h by moving two 10513 1.1 jruoho structures to the beginning of the file. 10514 1.1 jruoho 10515 1.1 jruoho After wake, clear GPE status register(s) before enabling GPEs. 10516 1.1 jruoho 10517 1.1.1.3.2.1 yamt After wake, clear/enable power button. (Perhaps we should clear/enable 10518 1.1.1.3.2.1 yamt all 10519 1.1 jruoho fixed events upon wake.) 10520 1.1 jruoho 10521 1.1 jruoho Fixed a couple of possible memory leaks in the Namespace manager. 10522 1.1 jruoho 10523 1.1 jruoho Integrated latest acnetbsd.h file. 10524 1.1 jruoho 10525 1.1 jruoho ---------------------------------------- 10526 1.1 jruoho 11 February 2004. Summary of changes for version 20040211: 10527 1.1 jruoho 10528 1.1 jruoho 10529 1.1 jruoho 1) ACPI CA Core Subsystem: 10530 1.1 jruoho 10531 1.1 jruoho Completed investigation and implementation of the call-by-reference 10532 1.1 jruoho mechanism for control method arguments. 10533 1.1 jruoho 10534 1.1 jruoho Fixed a problem where a store of an object into an indexed package could 10535 1.1 jruoho fail if the store occurs within a different method than the method that 10536 1.1 jruoho created the package. 10537 1.1 jruoho 10538 1.1.1.3.2.1 yamt Fixed a problem where the ToDecimal operator could return incorrect 10539 1.1.1.3.2.1 yamt results. 10540 1.1 jruoho 10541 1.1.1.3.2.1 yamt Fixed a problem where the CopyObject operator could fail on some of the 10542 1.1.1.3.2.1 yamt more 10543 1.1 jruoho obscure objects (e.g., Reference objects.) 10544 1.1 jruoho 10545 1.1 jruoho Improved the output of the Debug object to display buffer, package, and 10546 1.1 jruoho index objects. 10547 1.1 jruoho 10548 1.1.1.3.2.1 yamt Fixed a problem where constructs of the form "RefOf (ArgX)" did not 10549 1.1.1.3.2.1 yamt return 10550 1.1 jruoho the expected result. 10551 1.1 jruoho 10552 1.1 jruoho Added permanent ACPI_REPORT_ERROR macros for all instances of the 10553 1.1 jruoho ACPI_AML_INTERNAL exception. 10554 1.1 jruoho 10555 1.1 jruoho Integrated latest version of acfreebsd.h 10556 1.1 jruoho 10557 1.1 jruoho ---------------------------------------- 10558 1.1 jruoho 16 January 2004. Summary of changes for version 20040116: 10559 1.1 jruoho 10560 1.1 jruoho The purpose of this release is primarily to update the copyright years in 10561 1.1 jruoho each module, thus causing a huge number of diffs. There are a few small 10562 1.1 jruoho functional changes, however. 10563 1.1 jruoho 10564 1.1 jruoho 1) ACPI CA Core Subsystem: 10565 1.1 jruoho 10566 1.1.1.3.2.1 yamt Improved error messages when there is a problem finding one or more of 10567 1.1.1.3.2.1 yamt the 10568 1.1 jruoho required base ACPI tables 10569 1.1 jruoho 10570 1.1 jruoho Reintroduced the definition of APIC_HEADER in actbl.h 10571 1.1 jruoho 10572 1.1 jruoho Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h) 10573 1.1 jruoho 10574 1.1 jruoho Removed extraneous reference to NewObj in dsmthdat.c 10575 1.1 jruoho 10576 1.1 jruoho 2) iASL compiler 10577 1.1 jruoho 10578 1.1.1.3.2.1 yamt Fixed a problem introduced in December that disabled the correct 10579 1.1.1.3.2.1 yamt disassembly 10580 1.1 jruoho of Resource Templates 10581 1.1 jruoho 10582 1.1 jruoho 10583 1.1 jruoho ---------------------------------------- 10584 1.1 jruoho 03 December 2003. Summary of changes for version 20031203: 10585 1.1 jruoho 10586 1.1 jruoho 1) ACPI CA Core Subsystem: 10587 1.1 jruoho 10588 1.1 jruoho Changed the initialization of Operation Regions during subsystem 10589 1.1 jruoho init to perform two entire walks of the ACPI namespace; The first 10590 1.1 jruoho to initialize the regions themselves, the second to execute the 10591 1.1 jruoho _REG methods. This fixed some interdependencies across _REG 10592 1.1 jruoho methods found on some machines. 10593 1.1 jruoho 10594 1.1 jruoho Fixed a problem where a Store(Local0, Local1) could simply update 10595 1.1 jruoho the object reference count, and not create a new copy of the 10596 1.1 jruoho object if the Local1 is uninitialized. 10597 1.1 jruoho 10598 1.1 jruoho Implemented support for the _SST reserved method during sleep 10599 1.1 jruoho transitions. 10600 1.1 jruoho 10601 1.1 jruoho Implemented support to clear the SLP_TYP and SLP_EN bits when 10602 1.1 jruoho waking up, this is apparently required by some machines. 10603 1.1 jruoho 10604 1.1 jruoho When sleeping, clear the wake status only if SleepState is not S5. 10605 1.1 jruoho 10606 1.1 jruoho Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect 10607 1.1 jruoho pointer arithmetic advanced a string pointer too far. 10608 1.1 jruoho 10609 1.1 jruoho Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer 10610 1.1 jruoho could be returned if the requested table has not been loaded. 10611 1.1 jruoho 10612 1.1 jruoho Within the support for IRQ resources, restructured the handling of 10613 1.1 jruoho the active and edge/level bits. 10614 1.1 jruoho 10615 1.1 jruoho Fixed a few problems in AcpiPsxExecute() where memory could be 10616 1.1 jruoho leaked under certain error conditions. 10617 1.1 jruoho 10618 1.1 jruoho Improved error messages for the cases where the ACPI mode could 10619 1.1 jruoho not be entered. 10620 1.1 jruoho 10621 1.1 jruoho Code and Data Size: Current and previous core subsystem library 10622 1.1 jruoho sizes are shown below. These are the code and data sizes for the 10623 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 10624 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 10625 1.1 jruoho debug version of the code includes the debug output trace 10626 1.1 jruoho mechanism and has a much larger code and data size. Note that 10627 1.1 jruoho these values will vary depending on the efficiency of the compiler 10628 1.1 jruoho and the compiler options used during generation. 10629 1.1 jruoho 10630 1.1 jruoho Previous Release (20031029): 10631 1.1 jruoho Non-Debug Version: 74.4K Code, 10.1K Data, 84.5K Total 10632 1.1 jruoho Debug Version: 158.3K Code, 65.0K Data, 223.3K Total 10633 1.1 jruoho Current Release: 10634 1.1 jruoho Non-Debug Version: 74.8K Code, 10.1K Data, 84.9K Total 10635 1.1 jruoho Debug Version: 158.7K Code, 65.1K Data, 223.8K Total 10636 1.1 jruoho 10637 1.1 jruoho 2) iASL Compiler/Disassembler: 10638 1.1 jruoho 10639 1.1 jruoho Implemented a fix for the iASL disassembler where a bad index was 10640 1.1 jruoho generated. This was most noticeable on 64-bit platforms 10641 1.1 jruoho 10642 1.1 jruoho 10643 1.1 jruoho ---------------------------------------- 10644 1.1 jruoho 29 October 2003. Summary of changes for version 20031029: 10645 1.1 jruoho 10646 1.1 jruoho 1) ACPI CA Core Subsystem: 10647 1.1 jruoho 10648 1.1 jruoho 10649 1.1 jruoho Fixed a problem where a level-triggered GPE with an associated 10650 1.1 jruoho _Lxx control method was incorrectly cleared twice. 10651 1.1 jruoho 10652 1.1 jruoho Fixed a problem with the Field support code where an access can 10653 1.1 jruoho occur beyond the end-of-region if the field is non-aligned but 10654 1.1 jruoho extends to the very end of the parent region (resulted in an 10655 1.1 jruoho AE_AML_REGION_LIMIT exception.) 10656 1.1 jruoho 10657 1.1 jruoho Fixed a problem with ACPI Fixed Events where an RT Clock handler 10658 1.1 jruoho would not get invoked on an RTC event. The RTC event bitmasks for 10659 1.1 jruoho the PM1 registers were not being initialized properly. 10660 1.1 jruoho 10661 1.1 jruoho Implemented support for executing _STA and _INI methods for 10662 1.1 jruoho Processor objects. Although this is currently not part of the 10663 1.1 jruoho ACPI specification, there is existing ASL code that depends on the 10664 1.1 jruoho init-time execution of these methods. 10665 1.1 jruoho 10666 1.1 jruoho Implemented and deployed a GetDescriptorName function to decode 10667 1.1 jruoho the various types of internal descriptors. Guards against null 10668 1.1 jruoho descriptors during debug output also. 10669 1.1 jruoho 10670 1.1 jruoho Implemented and deployed a GetNodeName function to extract the 4- 10671 1.1 jruoho character namespace node name. This function simplifies the debug 10672 1.1 jruoho and error output, as well as guarding against null pointers during 10673 1.1 jruoho output. 10674 1.1 jruoho 10675 1.1 jruoho Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to 10676 1.1 jruoho simplify the debug and error output of 64-bit integers. This 10677 1.1 jruoho macro replaces the HIDWORD and LODWORD macros for dumping these 10678 1.1 jruoho integers. 10679 1.1 jruoho 10680 1.1 jruoho Updated the implementation of the Stall() operator to only call 10681 1.1 jruoho AcpiOsStall(), and also return an error if the operand is larger 10682 1.1 jruoho than 255. This preserves the required behavior of not 10683 1.1 jruoho relinquishing the processor, as would happen if AcpiOsSleep() was 10684 1.1 jruoho called for "long stalls". 10685 1.1 jruoho 10686 1.1 jruoho Constructs of the form "Store(LocalX,LocalX)" where LocalX is not 10687 1.1 jruoho initialized are now treated as NOOPs. 10688 1.1 jruoho 10689 1.1 jruoho Cleaned up a handful of warnings during 64-bit generation. 10690 1.1 jruoho 10691 1.1 jruoho Fixed a reported error where and incorrect GPE number was passed 10692 1.1 jruoho to the GPE dispatch handler. This value is only used for error 10693 1.1 jruoho output, however. Used this opportunity to clean up and streamline 10694 1.1 jruoho the GPE dispatch code. 10695 1.1 jruoho 10696 1.1 jruoho Code and Data Size: Current and previous core subsystem library 10697 1.1 jruoho sizes are shown below. These are the code and data sizes for the 10698 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 10699 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 10700 1.1 jruoho 10701 1.1 jruoho debug version of the code includes the debug output trace 10702 1.1 jruoho mechanism and has a much larger code and data size. Note that 10703 1.1 jruoho these values will vary depending on the efficiency of the compiler 10704 1.1 jruoho and the compiler options used during generation. 10705 1.1 jruoho 10706 1.1 jruoho Previous Release (20031002): 10707 1.1 jruoho Non-Debug Version: 74.1K Code, 9.7K Data, 83.8K Total 10708 1.1 jruoho Debug Version: 157.9K Code, 64.8K Data, 222.7K Total 10709 1.1 jruoho Current Release: 10710 1.1 jruoho Non-Debug Version: 74.4K Code, 10.1K Data, 84.5K Total 10711 1.1 jruoho Debug Version: 158.3K Code, 65.0K Data, 223.3K Total 10712 1.1 jruoho 10713 1.1 jruoho 10714 1.1 jruoho 2) iASL Compiler/Disassembler: 10715 1.1 jruoho 10716 1.1 jruoho Updated the iASL compiler to return an error if the operand to the 10717 1.1 jruoho Stall() operator is larger than 255. 10718 1.1 jruoho 10719 1.1 jruoho 10720 1.1 jruoho ---------------------------------------- 10721 1.1 jruoho 02 October 2003. Summary of changes for version 20031002: 10722 1.1 jruoho 10723 1.1 jruoho 10724 1.1 jruoho 1) ACPI CA Core Subsystem: 10725 1.1 jruoho 10726 1.1 jruoho Fixed a problem with Index Fields where the index was not 10727 1.1 jruoho incremented for fields that require multiple writes to the 10728 1.1 jruoho index/data registers (Fields that are wider than the data 10729 1.1 jruoho register.) 10730 1.1 jruoho 10731 1.1 jruoho Fixed a problem with all Field objects where a write could go 10732 1.1 jruoho beyond the end-of-field if the field was larger than the access 10733 1.1 jruoho granularity and therefore required multiple writes to complete the 10734 1.1 jruoho request. An extra write beyond the end of the field could happen 10735 1.1 jruoho inadvertently. 10736 1.1 jruoho 10737 1.1 jruoho Fixed a problem with Index Fields where a BUFFER_OVERFLOW error 10738 1.1 jruoho would incorrectly be returned if the width of the Data Register 10739 1.1 jruoho was larger than the specified field access width. 10740 1.1 jruoho 10741 1.1 jruoho Completed fixes for LoadTable() and Unload() and verified their 10742 1.1 jruoho operation. Implemented full support for the "DdbHandle" object 10743 1.1 jruoho throughout the ACPI CA subsystem. 10744 1.1 jruoho 10745 1.1 jruoho Implemented full support for the MADT and ECDT tables in the ACPI 10746 1.1 jruoho CA header files. Even though these tables are not directly 10747 1.1 jruoho consumed by ACPI CA, the header definitions are useful for ACPI 10748 1.1 jruoho device drivers. 10749 1.1 jruoho 10750 1.1 jruoho Integrated resource descriptor fixes posted to the Linux ACPI 10751 1.1 jruoho list. This included checks for minimum descriptor length, and 10752 1.1 jruoho support for trailing NULL strings within descriptors that have 10753 1.1 jruoho optional string elements. 10754 1.1 jruoho 10755 1.1 jruoho Code and Data Size: Current and previous core subsystem library 10756 1.1 jruoho sizes are shown below. These are the code and data sizes for the 10757 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 10758 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 10759 1.1 jruoho debug version of the code includes the debug output trace 10760 1.1 jruoho mechanism and has a much larger code and data size. Note that 10761 1.1 jruoho these values will vary depending on the efficiency of the compiler 10762 1.1 jruoho and the compiler options used during generation. 10763 1.1 jruoho 10764 1.1 jruoho Previous Release (20030918): 10765 1.1 jruoho Non-Debug Version: 73.9K Code, 9.7K Data, 83.6K Total 10766 1.1 jruoho Debug Version: 157.3K Code, 64.5K Data, 221.8K Total 10767 1.1 jruoho Current Release: 10768 1.1 jruoho Non-Debug Version: 74.1K Code, 9.7K Data, 83.8K Total 10769 1.1 jruoho Debug Version: 157.9K Code, 64.8K Data, 222.7K Total 10770 1.1 jruoho 10771 1.1 jruoho 10772 1.1 jruoho 2) iASL Compiler: 10773 1.1 jruoho 10774 1.1 jruoho Implemented detection of non-ASCII characters within the input 10775 1.1 jruoho source ASL file. This catches attempts to compile binary (AML) 10776 1.1 jruoho files early in the compile, with an informative error message. 10777 1.1 jruoho 10778 1.1 jruoho Fixed a problem where the disassembler would fault if the output 10779 1.1 jruoho filename could not be generated or if the output file could not be 10780 1.1 jruoho opened. 10781 1.1 jruoho 10782 1.1 jruoho ---------------------------------------- 10783 1.1 jruoho 18 September 2003. Summary of changes for version 20030918: 10784 1.1 jruoho 10785 1.1 jruoho 10786 1.1 jruoho 1) ACPI CA Core Subsystem: 10787 1.1 jruoho 10788 1.1 jruoho Found and fixed a longstanding problem with the late execution of 10789 1.1 jruoho the various deferred AML opcodes (such as Operation Regions, 10790 1.1 jruoho Buffer Fields, Buffers, and Packages). If the name string 10791 1.1 jruoho specified for the name of the new object placed the object in a 10792 1.1 jruoho scope other than the current scope, the initialization/execution 10793 1.1 jruoho of the opcode failed. The solution to this problem was to 10794 1.1 jruoho implement a mechanism where the late execution of such opcodes 10795 1.1 jruoho does not attempt to lookup/create the name a second time in an 10796 1.1 jruoho incorrect scope. This fixes the "region size computed 10797 1.1 jruoho incorrectly" problem. 10798 1.1 jruoho 10799 1.1 jruoho Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a 10800 1.1 jruoho Global Lock AE_BAD_PARAMETER error. 10801 1.1 jruoho 10802 1.1 jruoho Fixed several 64-bit issues with prototypes, casting and data 10803 1.1 jruoho types. 10804 1.1 jruoho 10805 1.1 jruoho Removed duplicate prototype from acdisasm.h 10806 1.1 jruoho 10807 1.1 jruoho Fixed an issue involving EC Operation Region Detach (Shaohua Li) 10808 1.1 jruoho 10809 1.1 jruoho Code and Data Size: Current and previous core subsystem library 10810 1.1 jruoho sizes are shown below.

Summary of changes for version 20030619: 10858 1.1 jruoho 10859 1.1 jruoho 1) ACPI CA Core Subsystem: 10860 1.1 jruoho 10861 1.1 jruoho Fix To/FromBCD, eliminating the need for an arch-specific #define. 10862 1.1 jruoho 10863 1.1 jruoho Do not acquire a semaphore in the S5 shutdown path. 10864 1.1 jruoho 10865 1.1 jruoho Fix ex_digits_needed for 0. (Takayoshi Kochi) 10866 1.1 jruoho 10867 1.1 jruoho Fix sleep/stall code reversal. (Andi Kleen) 10868 1.1 jruoho 10869 1.1 jruoho Revert a change having to do with control method calling 10870 1.1 jruoho semantics. 10871 1.1 jruoho 10872 1.1 jruoho 2) Linux: 10873 1.1 jruoho 10874 1.1 jruoho acpiphp update (Takayoshi Kochi) 10875 1.1 jruoho 10876 1.1 jruoho Export acpi_disabled for sonypi (Stelian Pop) 10877 1.1 jruoho 10878 1.1 jruoho Mention acpismp=force in config help 10879 1.1 jruoho 10880 1.1 jruoho Re-add acpitable.c and acpismp=force. This improves backwards 10881 1.1 jruoho 10882 1.1 jruoho compatibility and also cleans up the code to a significant degree. 10883 1.1 jruoho 10884 1.1 jruoho Add ASUS Value-add driver (Karol Kozimor and Julien Lerouge) 10885 1.1 jruoho 10886 1.1 jruoho ---------------------------------------- 10887 1.1 jruoho 22 May 2003. Summary of changes for version 20030522: 10888 1.1 jruoho 10889 1.1 jruoho 1) ACPI CA Core Subsystem: 10890 1.1 jruoho 10891 1.1 jruoho Found and fixed a reported problem where an AE_NOT_FOUND error 10892 1.1 jruoho occurred occasionally during _BST evaluation. This turned out to 10893 1.1 jruoho be an Owner ID allocation issue where a called method did not get 10894 1.1 jruoho a new ID assigned to it. Eventually, (after 64k calls), the Owner 10895 1.1 jruoho ID UINT16 would wraparound so that the ID would be the same as the 10896 1.1 jruoho caller's and the called method would delete the caller's 10897 1.1 jruoho namespace. 10898 1.1 jruoho 10899 1.1 jruoho Implemented extended error reporting for control methods that are 10900 1.1 jruoho aborted due to a run-time exception. Output includes the exact 10901 1.1 jruoho AML instruction that caused the method abort, a dump of the method 10902 1.1 jruoho locals and arguments at the time of the abort, and a trace of all 10903 1.1 jruoho nested control method calls. 10904 1.1 jruoho 10905 1.1 jruoho Modified the interpreter to allow the creation of buffers of zero 10906 1.1 jruoho length from the AML code. Implemented new code to ensure that no 10907 1.1 jruoho attempt is made to actually allocate a memory buffer (of length 10908 1.1 jruoho zero) - instead, a simple buffer object with a NULL buffer pointer 10909 1.1 jruoho and length zero is created. A warning is no longer issued when 10910 1.1 jruoho the AML attempts to create a zero-length buffer. 10911 1.1 jruoho 10912 1.1 jruoho Implemented a workaround for the "leading asterisk issue" in 10913 1.1 jruoho _HIDs, _UIDs, and _CIDs in the AML interpreter. One leading 10914 1.1 jruoho asterisk is automatically removed if present in any HID, UID, or 10915 1.1 jruoho CID strings. The iASL compiler will still flag this asterisk as 10916 1.1 jruoho an error, however. 10917 1.1 jruoho 10918 1.1 jruoho Implemented full support for _CID methods that return a package of 10919 1.1 jruoho multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() interface 10920 1.1 jruoho now additionally returns a device _CID list if present. This 10921 1.1 jruoho required a change to the external interface in order to pass an 10922 1.1 jruoho ACPI_BUFFER object as a parameter since the _CID list is of 10923 1.1 jruoho variable length. 10924 1.1 jruoho 10925 1.1 jruoho Fixed a problem with the new AE_SAME_HANDLER exception where 10926 1.1 jruoho handler initialization code did not know about this exception. 10927 1.1 jruoho 10928 1.1 jruoho Code and Data Size: Current and previous core subsystem library 10929 1.1 jruoho sizes are shown below. These are the code and data sizes for the 10930 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 10931 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 10932 1.1 jruoho debug version of the code includes the debug output trace 10933 1.1 jruoho mechanism and has a much larger code and data size. Note that 10934 1.1 jruoho these values will vary depending on the efficiency of the compiler 10935 1.1 jruoho and the compiler options used during generation. 10936 1.1 jruoho 10937 1.1 jruoho Previous Release (20030509): 10938 1.1 jruoho Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total 10939 1.1 jruoho Debug Version: 156.1K Code, 63.9K Data, 220.0K Total 10940 1.1 jruoho Current Release: 10941 1.1 jruoho Non-Debug Version: 73.7K Code, 9.7K Data, 83.4K Total 10942 1.1 jruoho Debug Version: 156.9K Code, 64.2K Data, 221.1K Total 10943 1.1 jruoho 10944 1.1 jruoho 10945 1.1 jruoho 2) Linux: 10946 1.1 jruoho 10947 1.1 jruoho Fixed a bug in which we would reinitialize the ACPI interrupt 10948 1.1 jruoho after it was already working, thus disabling all ACPI and the IRQs 10949 1.1 jruoho for any other device sharing the interrupt. (Thanks to Stian 10950 1.1 jruoho Jordet) 10951 1.1 jruoho 10952 1.1 jruoho Toshiba driver update (John Belmonte) 10953 1.1 jruoho 10954 1.1 jruoho Return only 0 or 1 for our interrupt handler status (Andrew 10955 1.1 jruoho Morton) 10956 1.1 jruoho 10957 1.1 jruoho 10958 1.1 jruoho 3) iASL Compiler: 10959 1.1 jruoho 10960 1.1 jruoho Fixed a reported problem where multiple (nested) ElseIf() 10961 1.1 jruoho statements were not handled correctly by the compiler, resulting 10962 1.1 jruoho in incorrect warnings and incorrect AML code. This was a problem 10963 1.1 jruoho in both the ASL parser and the code generator. 10964 1.1 jruoho 10965 1.1 jruoho 10966 1.1 jruoho 4) Documentation: 10967 1.1 jruoho 10968 1.1 jruoho Added changes to existing interfaces, new exception codes, and new 10969 1.1 jruoho text concerning reference count object management versus garbage 10970 1.1 jruoho collection. 10971 1.1 jruoho 10972 1.1 jruoho ---------------------------------------- 10973 1.1 jruoho 09 May 2003. Summary of changes for version 20030509. 10974 1.1 jruoho 10975 1.1 jruoho 10976 1.1 jruoho 1) ACPI CA Core Subsystem: 10977 1.1 jruoho 10978 1.1 jruoho Changed the subsystem initialization sequence to hold off 10979 1.1 jruoho installation of address space handlers until the hardware has been 10980 1.1 jruoho initialized and the system has entered ACPI mode. This is because 10981 1.1 jruoho the installation of space handlers can cause _REG methods to be 10982 1.1 jruoho run. Previously, the _REG methods could potentially be run before 10983 1.1 jruoho ACPI mode was enabled. 10984 1.1 jruoho 10985 1.1 jruoho Fixed some memory leak issues related to address space handler and 10986 1.1 jruoho notify handler installation. There were some problems with the 10987 1.1 jruoho reference count mechanism caused by the fact that the handler 10988 1.1 jruoho objects are shared across several namespace objects. 10989 1.1 jruoho 10990 1.1 jruoho Fixed a reported problem where reference counts within the 10991 1.1 jruoho namespace were not properly updated when named objects created by 10992 1.1 jruoho method execution were deleted. 10993 1.1 jruoho 10994 1.1 jruoho Fixed a reported problem where multiple SSDTs caused a deletion 10995 1.1 jruoho issue during subsystem termination. Restructured the table data 10996 1.1 jruoho structures to simplify the linked lists and the related code. 10997 1.1 jruoho 10998 1.1 jruoho Fixed a problem where the table ID associated with secondary 10999 1.1 jruoho tables (SSDTs) was not being propagated into the namespace objects 11000 1.1 jruoho created by those tables. This would only present a problem for 11001 1.1 jruoho tables that are unloaded at run-time, however. 11002 1.1 jruoho 11003 1.1 jruoho Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE 11004 1.1 jruoho type as the length parameter (instead of UINT32). 11005 1.1 jruoho 11006 1.1 jruoho Solved a long-standing problem where an ALREADY_EXISTS error 11007 1.1 jruoho appears on various systems. This problem could happen when there 11008 1.1 jruoho are multiple PCI_Config operation regions under a single PCI root 11009 1.1 jruoho bus. This doesn't happen very frequently, but there are some 11010 1.1 jruoho systems that do this in the ASL. 11011 1.1 jruoho 11012 1.1 jruoho Fixed a reported problem where the internal DeleteNode function 11013 1.1 jruoho was incorrectly handling the case where a namespace node was the 11014 1.1 jruoho first in the parent's child list, and had additional peers (not 11015 1.1 jruoho the only child, but first in the list of children.) 11016 1.1 jruoho 11017 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11018 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11019 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11020 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11021 1.1 jruoho version of the code includes the debug output trace mechanism and 11022 1.1 jruoho has a much larger code and data size. Note that these values will 11023 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 11024 1.1 jruoho options used during generation. 11025 1.1 jruoho 11026 1.1 jruoho Previous Release 11027 1.1 jruoho Non-Debug Version: 73.7K Code, 9.5K Data, 83.2K Total 11028 1.1 jruoho Debug Version: 156.1K Code, 63.6K Data, 219.7K Total 11029 1.1 jruoho Current Release: 11030 1.1 jruoho Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total 11031 1.1 jruoho Debug Version: 156.1K Code, 63.9K Data, 220.0K Total 11032 1.1 jruoho 11033 1.1 jruoho 11034 1.1 jruoho 2) Linux: 11035 1.1 jruoho 11036 1.1 jruoho Allow ":" in OS override string (Ducrot Bruno) 11037 1.1 jruoho 11038 1.1 jruoho Kobject fix (Greg KH) 11039 1.1 jruoho 11040 1.1 jruoho 11041 1.1 jruoho 3 iASL Compiler/Disassembler: 11042 1.1 jruoho 11043 1.1 jruoho Fixed a problem in the generation of the C source code files (AML 11044 1.1 jruoho is emitted in C source statements for BIOS inclusion) where the 11045 1.1 jruoho Ascii dump that appears within a C comment at the end of each line 11046 1.1 jruoho could cause a compile time error if the AML sequence happens to 11047 1.1 jruoho have an open comment or close comment sequence embedded. 11048 1.1 jruoho 11049 1.1 jruoho 11050 1.1 jruoho ---------------------------------------- 11051 1.1 jruoho 24 April 2003. Summary of changes for version 20030424. 11052 1.1 jruoho 11053 1.1 jruoho 11054 1.1 jruoho 1) ACPI CA Core Subsystem: 11055 1.1 jruoho 11056 1.1 jruoho Support for big-endian systems has been implemented. Most of the 11057 1.1 jruoho support has been invisibly added behind big-endian versions of the 11058 1.1 jruoho ACPI_MOVE_* macros. 11059 1.1 jruoho 11060 1.1 jruoho Fixed a problem in AcpiHwDisableGpeBlock() and 11061 1.1 jruoho AcpiHwClearGpeBlock() where an incorrect offset was passed to the 11062 1.1 jruoho low level hardware write routine. The offset parameter was 11063 1.1 jruoho actually eliminated from the low level read/write routines because 11064 1.1 jruoho they had become obsolete. 11065 1.1 jruoho 11066 1.1 jruoho Fixed a problem where a handler object was deleted twice during 11067 1.1 jruoho the removal of a fixed event handler. 11068 1.1 jruoho 11069 1.1 jruoho 11070 1.1 jruoho 2) Linux: 11071 1.1 jruoho 11072 1.1 jruoho A fix for SMP systems with link devices was contributed by 11073 1.1 jruoho 11074 1.1 jruoho Compaq's Dan Zink. 11075 1.1 jruoho 11076 1.1 jruoho (2.5) Return whether we handled the interrupt in our IRQ handler. 11077 1.1 jruoho (Linux ISRs no longer return void, so we can propagate the handler 11078 1.1 jruoho return value from the ACPI CA core back to the OS.) 11079 1.1 jruoho 11080 1.1 jruoho 11081 1.1 jruoho 11082 1.1 jruoho 3) Documentation: 11083 1.1 jruoho 11084 1.1 jruoho The ACPI CA Programmer Reference has been updated to reflect new 11085 1.1 jruoho interfaces and changes to existing interfaces. 11086 1.1 jruoho 11087 1.1 jruoho ---------------------------------------- 11088 1.1 jruoho 28 March 2003. Summary of changes for version 20030328. 11089 1.1 jruoho 11090 1.1 jruoho 1) ACPI CA Core Subsystem: 11091 1.1 jruoho 11092 1.1 jruoho The GPE Block Device support has been completed. New interfaces 11093 1.1 jruoho are AcpiInstallGpeBlock and AcpiRemoveGpeBlock. The Event 11094 1.1 jruoho interfaces (enable, disable, clear, getstatus) have been split 11095 1.1 jruoho into separate interfaces for Fixed Events and General Purpose 11096 1.1 jruoho Events (GPEs) in order to support GPE Block Devices properly. 11097 1.1 jruoho 11098 1.1 jruoho Fixed a problem where the error message "Failed to acquire 11099 1.1 jruoho semaphore" would appear during operations on the embedded 11100 1.1 jruoho controller (EC). 11101 1.1 jruoho 11102 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11103 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11104 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11105 1.1 jruoho values do not include any ACPI driver or OSPM code.

Summary of changes for version 20030228. 11121 1.1 jruoho 11122 1.1 jruoho 11123 1.1 jruoho 1) ACPI CA Core Subsystem: 11124 1.1 jruoho 11125 1.1 jruoho The GPE handling and dispatch code has been completely overhauled 11126 1.1 jruoho in preparation for support of GPE Block Devices (ID ACPI0006). 11127 1.1 jruoho This affects internal data structures and code only; there should 11128 1.1 jruoho be no differences visible externally. One new file has been 11129 1.1 jruoho added, evgpeblk.c 11130 1.1 jruoho 11131 1.1 jruoho The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only 11132 1.1 jruoho fields that are used to determine the GPE block lengths. The 11133 1.1 jruoho REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address 11134 1.1 jruoho structures are ignored. This is per the ACPI specification but it 11135 1.1 jruoho isn't very clear. The full 256 Block 0/1 GPEs are now supported 11136 1.1 jruoho (the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128). 11137 1.1 jruoho 11138 1.1 jruoho In the SCI interrupt handler, removed the read of the PM1_CONTROL 11139 1.1 jruoho register to look at the SCI_EN bit. On some machines, this read 11140 1.1 jruoho causes an SMI event and greatly slows down SCI events. (This may 11141 1.1 jruoho in fact be the cause of slow battery status response on some 11142 1.1 jruoho systems.) 11143 1.1 jruoho 11144 1.1 jruoho Fixed a problem where a store of a NULL string to a package object 11145 1.1 jruoho could cause the premature deletion of the object. This was seen 11146 1.1 jruoho during execution of the battery _BIF method on some systems, 11147 1.1 jruoho resulting in no battery data being returned. 11148 1.1 jruoho 11149 1.1 jruoho Added AcpiWalkResources interface to simplify parsing of resource 11150 1.1 jruoho lists. 11151 1.1 jruoho 11152 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11153 1.1 jruoho below.

Apparently, some BIOS 11211 1.1 jruoho programmers believe that this is a NOOP. Since this store doesn't 11212 1.1 jruoho do anything anyway, the new prototype behavior will ignore this 11213 1.1 jruoho error. This is a case where we can relax the strict checking in 11214 1.1 jruoho the interpreter in the name of compatibility. 11215 1.1 jruoho 11216 1.1 jruoho 11217 1.1 jruoho 2) Linux 11218 1.1 jruoho 11219 1.1 jruoho The AcpiSrc Source Conversion Utility has been released with the 11220 1.1 jruoho Linux package for the first time.

Summary of changes for version 20030109. 11265 1.1 jruoho 11266 1.1 jruoho 1) ACPI CA Core Subsystem: 11267 1.1 jruoho 11268 1.1 jruoho Changed the behavior of the internal Buffer-to-String conversion 11269 1.1 jruoho function. The current ACPI specification states that the contents 11270 1.1 jruoho of the buffer are "converted to a string of two-character 11271 1.1 jruoho hexadecimal numbers, each separated by a space". Unfortunately, 11272 1.1 jruoho this definition is not backwards compatible with existing ACPI 1.0 11273 1.1 jruoho implementations (although the behavior was not defined in the ACPI 11274 1.1 jruoho 1.0 specification). The new behavior simply copies data from the 11275 1.1 jruoho buffer to the string until a null character is found or the end of 11276 1.1 jruoho the buffer is reached. The new String object is always null 11277 1.1 jruoho terminated. This problem was seen during the generation of _BIF 11278 1.1 jruoho battery data where incorrect strings were returned for battery 11279 1.1 jruoho type, etc. This will also require an errata to the ACPI 11280 1.1 jruoho specification. 11281 1.1 jruoho 11282 1.1 jruoho Renamed all instances of NATIVE_UINT and NATIVE_INT to 11283 1.1 jruoho ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively. 11284 1.1 jruoho 11285 1.1 jruoho Copyright in all module headers (both Linux and non-Linux) has be 11286 1.1 jruoho updated to 2003. 11287 1.1 jruoho 11288 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11289 1.1 jruoho below.

Summary of changes for version 20021205. 11389 1.1 jruoho 11390 1.1 jruoho 1) ACPI CA Core Subsystem: 11391 1.1 jruoho 11392 1.1 jruoho Fixed a problem where a store to a String or Buffer object could 11393 1.1 jruoho cause corruption of the DSDT if the object type being stored was 11394 1.1 jruoho the same as the target object type and the length of the object 11395 1.1 jruoho being stored was equal to or smaller than the original (existing) 11396 1.1 jruoho target object. This was seen to cause corruption of battery _BIF 11397 1.1 jruoho buffers if the _BIF method modified the buffer on the fly. 11398 1.1 jruoho 11399 1.1 jruoho Fixed a problem where an internal error was generated if a control 11400 1.1 jruoho method invocation was used in an OperationRegion, Buffer, or 11401 1.1 jruoho Package declaration. This was caused by the deferred parsing of 11402 1.1 jruoho the control method and thus the deferred creation of the internal 11403 1.1 jruoho method object. The solution to this problem was to create the 11404 1.1 jruoho internal method object at the moment the method is encountered in 11405 1.1 jruoho the first pass - so that subsequent references to the method will 11406 1.1 jruoho able to obtain the required parameter count and thus properly 11407 1.1 jruoho parse the method invocation. This problem presented itself as an 11408 1.1 jruoho AE_AML_INTERNAL during the pass 1 parse phase during table load. 11409 1.1 jruoho 11410 1.1 jruoho Fixed a problem where the internal String object copy routine did 11411 1.1 jruoho not always allocate sufficient memory for the target String object 11412 1.1 jruoho and caused memory corruption. This problem was seen to cause 11413 1.1 jruoho "Allocation already present in list!" errors as memory allocation 11414 1.1 jruoho became corrupted. 11415 1.1 jruoho 11416 1.1 jruoho Implemented a new function for the evaluation of namespace objects 11417 1.1 jruoho that allows the specification of the allowable return object 11418 1.1 jruoho types. This simplifies a lot of code that checks for a return 11419 1.1 jruoho object of one or more specific objects returned from the 11420 1.1 jruoho evaluation (such as _STA, etc.) This may become and external 11421 1.1 jruoho function if it would be useful to ACPI-related drivers. 11422 1.1 jruoho 11423 1.1 jruoho Completed another round of prefixing #defines with "ACPI_" for 11424 1.1 jruoho clarity. 11425 1.1 jruoho 11426 1.1 jruoho Completed additional code restructuring to allow more modular 11427 1.1 jruoho linking for iASL compiler and AcpiExec. Several files were split 11428 1.1 jruoho creating new files. New files: nsparse.c dsinit.c evgpe.c 11429 1.1 jruoho 11430 1.1 jruoho Implemented an abort mechanism to terminate an executing control 11431 1.1 jruoho method via the AML debugger. This feature is useful for debugging 11432 1.1 jruoho control methods that depend (wait) for specific hardware 11433 1.1 jruoho responses. 11434 1.1 jruoho 11435 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11436 1.1 jruoho below.

If specified in the ASL, the optional "Resource 11456 1.1 jruoho Source Index" and "Resource Source" fields were not inserted into 11457 1.1 jruoho the correct location within the AML resource descriptor, creating 11458 1.1 jruoho an invalid descriptor. 11459 1.1 jruoho 11460 1.1 jruoho Fixed a disassembler problem for "Interrupt" resource descriptors. 11461 1.1 jruoho The optional "Resource Source Index" and "Resource Source" fields 11462 1.1 jruoho were ignored. 11463 1.1 jruoho 11464 1.1 jruoho 11465 1.1 jruoho ---------------------------------------- 11466 1.1 jruoho 22 November 2002. Summary of changes for version 20021122. 11467 1.1 jruoho 11468 1.1 jruoho 11469 1.1 jruoho 1) ACPI CA Core Subsystem: 11470 1.1 jruoho 11471 1.1 jruoho Fixed a reported problem where an object stored to a Method Local 11472 1.1 jruoho or Arg was not copied to a new object during the store - the 11473 1.1 jruoho object pointer was simply copied to the Local/Arg. This caused 11474 1.1 jruoho all subsequent operations on the Local/Arg to also affect the 11475 1.1 jruoho original source of the store operation. 11476 1.1 jruoho 11477 1.1 jruoho Fixed a problem where a store operation to a Method Local or Arg 11478 1.1 jruoho was not completed properly if the Local/Arg contained a reference 11479 1.1 jruoho (from RefOf) to a named field. The general-purpose store-to- 11480 1.1 jruoho namespace-node code is now used so that this case is handled 11481 1.1 jruoho automatically. 11482 1.1 jruoho 11483 1.1 jruoho Fixed a problem where the internal object copy routine would cause 11484 1.1 jruoho a protection fault if the object being copied was a Package and 11485 1.1 jruoho contained either 1) a NULL package element or 2) a nested sub- 11486 1.1 jruoho package. 11487 1.1 jruoho 11488 1.1 jruoho Fixed a problem with the GPE initialization that resulted from an 11489 1.1 jruoho ambiguity in the ACPI specification. One section of the 11490 1.1 jruoho specification states that both the address and length of the GPE 11491 1.1 jruoho block must be zero if the block is not supported. Another section 11492 1.1 jruoho implies that only the address need be zero if the block is not 11493 1.1 jruoho supported. The code has been changed so that both the address and 11494 1.1 jruoho the length must be non-zero to indicate a valid GPE block (i.e., 11495 1.1 jruoho if either the address or the length is zero, the GPE block is 11496 1.1 jruoho invalid.) 11497 1.1 jruoho 11498 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11499 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11500 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11501 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11502 1.1 jruoho version of the code includes the debug output trace mechanism and 11503 1.1 jruoho has a much larger code and data size. Note that these values will 11504 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 11505 1.1 jruoho options used during generation. 11506 1.1 jruoho 11507 1.1 jruoho Previous Release 11508 1.1 jruoho Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total 11509 1.1 jruoho Debug Version: 152.7K Code, 63.2K Data, 215.5K Total 11510 1.1 jruoho Current Release: 11511 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 11512 1.1 jruoho Debug Version: 152.9K Code, 63.3K Data, 216.2K Total 11513 1.1 jruoho 11514 1.1 jruoho 11515 1.1 jruoho 2) Linux 11516 1.1 jruoho 11517 1.1 jruoho Cleaned up EC driver. Exported an external EC read/write 11518 1.1 jruoho interface. By going through this, other drivers (most notably 11519 1.1 jruoho sonypi) will be able to serialize access to the EC. 11520 1.1 jruoho 11521 1.1 jruoho 11522 1.1 jruoho 3) iASL Compiler/Disassembler 11523 1.1 jruoho 11524 1.1 jruoho Implemented support to optionally generate include files for both 11525 1.1 jruoho ASM and C (the -i switch). This simplifies BIOS development by 11526 1.1 jruoho automatically creating include files that contain external 11527 1.1 jruoho declarations for the symbols that are created within the 11528 1.1 jruoho 11529 1.1 jruoho (optionally generated) ASM and C AML source files. 11530 1.1 jruoho 11531 1.1 jruoho 11532 1.1 jruoho ---------------------------------------- 11533 1.1 jruoho 15 November 2002. Summary of changes for version 20021115. 11534 1.1 jruoho 11535 1.1 jruoho 1) ACPI CA Core Subsystem: 11536 1.1 jruoho 11537 1.1 jruoho Fixed a memory leak problem where an error during resolution of 11538 1.1 jruoho 11539 1.1 jruoho method arguments during a method invocation from another method 11540 1.1 jruoho failed to cleanup properly by deleting all successfully resolved 11541 1.1 jruoho argument objects. 11542 1.1 jruoho 11543 1.1 jruoho Fixed a problem where the target of the Index() operator was not 11544 1.1 jruoho correctly constructed if the source object was a package. This 11545 1.1 jruoho problem has not been detected because the use of a target operand 11546 1.1 jruoho with Index() is very rare. 11547 1.1 jruoho 11548 1.1 jruoho Fixed a problem with the Index() operator where an attempt was 11549 1.1 jruoho made to delete the operand objects twice. 11550 1.1 jruoho 11551 1.1 jruoho Fixed a problem where an attempt was made to delete an operand 11552 1.1 jruoho twice during execution of the CondRefOf() operator if the target 11553 1.1 jruoho did not exist. 11554 1.1 jruoho 11555 1.1 jruoho Implemented the first of perhaps several internal create object 11556 1.1 jruoho functions that create and initialize a specific object type. This 11557 1.1 jruoho consolidates duplicated code wherever the object is created, thus 11558 1.1 jruoho shrinking the size of the subsystem. 11559 1.1 jruoho 11560 1.1 jruoho Implemented improved debug/error messages for errors that occur 11561 1.1 jruoho during nested method invocations. All executing method pathnames 11562 1.1 jruoho are displayed (with the error) as the call stack is unwound - thus 11563 1.1 jruoho simplifying debug. 11564 1.1 jruoho 11565 1.1 jruoho Fixed a problem introduced in the 10/02 release that caused 11566 1.1 jruoho premature deletion of a buffer object if a buffer was used as an 11567 1.1 jruoho ASL operand where an integer operand is required (Thus causing an 11568 1.1 jruoho implicit object conversion from Buffer to Integer.) The change in 11569 1.1 jruoho the 10/02 release was attempting to fix a memory leak (albeit 11570 1.1 jruoho incorrectly.) 11571 1.1 jruoho 11572 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11573 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11574 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11575 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11576 1.1 jruoho version of the code includes the debug output trace mechanism and 11577 1.1 jruoho has a much larger code and data size. Note that these values will 11578 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 11579 1.1 jruoho options used during generation. 11580 1.1 jruoho 11581 1.1 jruoho Previous Release 11582 1.1 jruoho Non-Debug Version: 71.9K Code, 9.1K Data, 81.0K Total 11583 1.1 jruoho Debug Version: 153.1K Code, 63.3K Data, 216.4K Total 11584 1.1 jruoho Current Release: 11585 1.1 jruoho Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total 11586 1.1 jruoho Debug Version: 152.7K Code, 63.2K Data, 215.5K Total 11587 1.1 jruoho 11588 1.1 jruoho 11589 1.1 jruoho 2) Linux 11590 1.1 jruoho 11591 1.1 jruoho Changed the implementation of the ACPI semaphores to use down() 11592 1.1 jruoho instead of down_interruptable(). It is important that the 11593 1.1 jruoho execution of ACPI control methods not be interrupted by signals. 11594 1.1 jruoho Methods must run to completion, or the system may be left in an 11595 1.1 jruoho unknown/unstable state. 11596 1.1 jruoho 11597 1.1 jruoho Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not set. 11598 1.1 jruoho (Shawn Starr) 11599 1.1 jruoho 11600 1.1 jruoho 11601 1.1 jruoho 3) iASL Compiler/Disassembler 11602 1.1 jruoho 11603 1.1 jruoho 11604 1.1 jruoho Changed the default location of output files. All output files 11605 1.1 jruoho are now placed in the current directory by default instead of in 11606 1.1 jruoho the directory of the source file. This change may affect some 11607 1.1 jruoho existing makefiles, but it brings the behavior of the compiler in 11608 1.1 jruoho line with other similar tools. The location of the output files 11609 1.1 jruoho can be overridden with the -p command line switch. 11610 1.1 jruoho 11611 1.1 jruoho 11612 1.1 jruoho ---------------------------------------- 11613 1.1 jruoho 11 November 2002. Summary of changes for version 20021111. 11614 1.1 jruoho 11615 1.1 jruoho 11616 1.1 jruoho 0) ACPI Specification 2.0B is released and is now available at: 11617 1.1 jruoho http://www.acpi.info/index.html 11618 1.1 jruoho 11619 1.1 jruoho 11620 1.1 jruoho 1) ACPI CA Core Subsystem: 11621 1.1 jruoho 11622 1.1 jruoho Implemented support for the ACPI 2.0 SMBus Operation Regions. 11623 1.1 jruoho This includes the early detection and handoff of the request to 11624 1.1 jruoho the SMBus region handler (avoiding all of the complex field 11625 1.1 jruoho support code), and support for the bidirectional return packet 11626 1.1 jruoho from an SMBus write operation. This paves the way for the 11627 1.1 jruoho development of SMBus drivers in each host operating system. 11628 1.1 jruoho 11629 1.1 jruoho Fixed a problem where the semaphore WAIT_FOREVER constant was 11630 1.1 jruoho defined as 32 bits, but must be 16 bits according to the ACPI 11631 1.1 jruoho specification. This had the side effect of causing ASL 11632 1.1 jruoho Mutex/Event timeouts even though the ASL code requested a wait 11633 1.1 jruoho forever. Changed all internal references to the ACPI timeout 11634 1.1 jruoho parameter to 16 bits to prevent future problems. Changed the name 11635 1.1 jruoho of WAIT_FOREVER to ACPI_WAIT_FOREVER. 11636 1.1 jruoho 11637 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11638 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11639 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11640 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11641 1.1 jruoho version of the code includes the debug output trace mechanism and 11642 1.1 jruoho has a much larger code and data size. Note that these values will 11643 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 11644 1.1 jruoho options used during generation. 11645 1.1 jruoho 11646 1.1 jruoho Previous Release 11647 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 11648 1.1 jruoho Debug Version: 152.3K Code, 63.0K Data, 215.3K Total 11649 1.1 jruoho Current Release: 11650 1.1 jruoho Non-Debug Version: 71.9K Code, 9.1K Data, 81.0K Total 11651 1.1 jruoho Debug Version: 153.1K Code, 63.3K Data, 216.4K Total 11652 1.1 jruoho 11653 1.1 jruoho 11654 1.1 jruoho 2) Linux 11655 1.1 jruoho 11656 1.1 jruoho Module loading/unloading fixes (John Cagle) 11657 1.1 jruoho 11658 1.1 jruoho 11659 1.1 jruoho 3) iASL Compiler/Disassembler 11660 1.1 jruoho 11661 1.1 jruoho Added support for the SMBBlockProcessCall keyword (ACPI 2.0) 11662 1.1 jruoho 11663 1.1 jruoho Implemented support for the disassembly of all SMBus protocol 11664 1.1 jruoho keywords (SMBQuick, SMBWord, etc.) 11665 1.1 jruoho 11666 1.1 jruoho ---------------------------------------- 11667 1.1 jruoho 01 November 2002. Summary of changes for version 20021101. 11668 1.1 jruoho 11669 1.1 jruoho 11670 1.1 jruoho 1) ACPI CA Core Subsystem: 11671 1.1 jruoho 11672 1.1 jruoho Fixed a problem where platforms that have a GPE1 block but no GPE0 11673 1.1 jruoho block were not handled correctly. This resulted in a "GPE 11674 1.1 jruoho overlap" error message. GPE0 is no longer required. 11675 1.1 jruoho 11676 1.1 jruoho Removed code added in the previous release that inserted nodes 11677 1.1 jruoho into the namespace in alphabetical order. This caused some side- 11678 1.1 jruoho effects on various machines. The root cause of the problem is 11679 1.1 jruoho still under investigation since in theory, the internal ordering 11680 1.1 jruoho of the namespace nodes should not matter. 11681 1.1 jruoho 11682 1.1 jruoho 11683 1.1 jruoho Enhanced error reporting for the case where a named object is not 11684 1.1 jruoho found during control method execution. The full ACPI namepath 11685 1.1 jruoho (name reference) of the object that was not found is displayed in 11686 1.1 jruoho this case. 11687 1.1 jruoho 11688 1.1 jruoho Note: as a result of the overhaul of the namespace object types in 11689 1.1 jruoho the previous release, the namespace nodes for the predefined 11690 1.1 jruoho scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE 11691 1.1 jruoho instead of ACPI_TYPE_ANY. This simplifies the namespace 11692 1.1 jruoho management code but may affect code that walks the namespace tree 11693 1.1 jruoho looking for specific object types. 11694 1.1 jruoho 11695 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11696 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11697 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11698 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11699 1.1 jruoho version of the code includes the debug output trace mechanism and 11700 1.1 jruoho has a much larger code and data size. Note that these values will 11701 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 11702 1.1 jruoho options used during generation. 11703 1.1 jruoho 11704 1.1 jruoho Previous Release 11705 1.1 jruoho Non-Debug Version: 70.7K Code, 8.6K Data, 79.3K Total 11706 1.1 jruoho Debug Version: 151.7K Code, 62.4K Data, 214.1K Total 11707 1.1 jruoho Current Release: 11708 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 11709 1.1 jruoho Debug Version: 152.3K Code, 63.0K Data, 215.3K Total 11710 1.1 jruoho 11711 1.1 jruoho 11712 1.1 jruoho 2) Linux 11713 1.1 jruoho 11714 1.1 jruoho Fixed a problem introduced in the previous release where the 11715 1.1 jruoho Processor and Thermal objects were not recognized and installed in 11716 1.1 jruoho /proc. This was related to the scope type change described above. 11717 1.1 jruoho 11718 1.1 jruoho 11719 1.1 jruoho 3) iASL Compiler/Disassembler 11720 1.1 jruoho 11721 1.1 jruoho Implemented the -g option to get all of the required ACPI tables 11722 1.1 jruoho from the registry and save them to files (Windows version of the 11723 1.1 jruoho compiler only.) The required tables are the FADT, FACS, and DSDT. 11724 1.1 jruoho 11725 1.1 jruoho Added ACPI table checksum validation during table disassembly in 11726 1.1 jruoho order to catch corrupted tables. 11727 1.1 jruoho 11728 1.1 jruoho 11729 1.1 jruoho ---------------------------------------- 11730 1.1 jruoho 22 October 2002. Summary of changes for version 20021022. 11731 1.1 jruoho 11732 1.1 jruoho 1) ACPI CA Core Subsystem: 11733 1.1 jruoho 11734 1.1 jruoho Implemented a restriction on the Scope operator that the target 11735 1.1 jruoho must already exist in the namespace at the time the operator is 11736 1.1 jruoho encountered (during table load or method execution). In other 11737 1.1 jruoho words, forward references are not allowed and Scope() cannot 11738 1.1 jruoho create a new object. This changes the previous behavior where the 11739 1.1 jruoho interpreter would create the name if not found. This new behavior 11740 1.1 jruoho correctly enables the search-to-root algorithm during namespace 11741 1.1 jruoho lookup of the target name. Because of this upsearch, this fixes 11742 1.1 jruoho the known Compaq _SB_.OKEC problem and makes both the AML 11743 1.1 jruoho interpreter and iASL compiler compatible with other ACPI 11744 1.1 jruoho implementations. 11745 1.1 jruoho 11746 1.1 jruoho Completed a major overhaul of the internal ACPI object types for 11747 1.1 jruoho the ACPI Namespace and the associated operand objects. Many of 11748 1.1 jruoho these types had become obsolete with the introduction of the two- 11749 1.1 jruoho pass namespace load. This cleanup simplifies the code and makes 11750 1.1 jruoho the entire namespace load mechanism much clearer and easier to 11751 1.1 jruoho understand. 11752 1.1 jruoho 11753 1.1 jruoho Improved debug output for tracking scope opening/closing to help 11754 1.1 jruoho diagnose scoping issues. The old scope name as well as the new 11755 1.1 jruoho scope name are displayed. Also improved error messages for 11756 1.1 jruoho problems with ASL Mutex objects and error messages for GPE 11757 1.1 jruoho problems. 11758 1.1 jruoho 11759 1.1 jruoho Cleaned up the namespace dump code, removed obsolete code. 11760 1.1 jruoho 11761 1.1 jruoho All string output (for all namespace/object dumps) now uses the 11762 1.1 jruoho common ACPI string output procedure which handles escapes properly 11763 1.1 jruoho and does not emit non-printable characters. 11764 1.1 jruoho 11765 1.1 jruoho Fixed some issues with constants in the 64-bit version of the 11766 1.1 jruoho local C library (utclib.c) 11767 1.1 jruoho 11768 1.1 jruoho 11769 1.1 jruoho 2) Linux 11770 1.1 jruoho 11771 1.1 jruoho EC Driver: No longer attempts to acquire the Global Lock at 11772 1.1 jruoho interrupt level. 11773 1.1 jruoho 11774 1.1 jruoho 11775 1.1 jruoho 3) iASL Compiler/Disassembler 11776 1.1 jruoho 11777 1.1 jruoho Implemented ACPI 2.0B grammar change that disallows all Type 1 and 11778 1.1 jruoho 2 opcodes outside of a control method. This means that the 11779 1.1 jruoho "executable" operators (versus the "namespace" operators) cannot 11780 1.1 jruoho be used at the table level; they can only be used within a control 11781 1.1 jruoho method. 11782 1.1 jruoho 11783 1.1 jruoho Implemented the restriction on the Scope() operator where the 11784 1.1 jruoho target must already exist in the namespace at the time the 11785 1.1 jruoho operator is encountered (during ASL compilation). In other words, 11786 1.1 jruoho forward references are not allowed and Scope() cannot create a new 11787 1.1 jruoho object. This makes the iASL compiler compatible with other ACPI 11788 1.1 jruoho implementations and makes the Scope() implementation adhere to the 11789 1.1 jruoho ACPI specification. 11790 1.1 jruoho 11791 1.1 jruoho Fixed a problem where namepath optimization for the Alias operator 11792 1.1 jruoho was optimizing the wrong path (of the two namepaths.) This caused 11793 1.1 jruoho a "Missing alias link" error message. 11794 1.1 jruoho 11795 1.1 jruoho Fixed a problem where an "unknown reserved name" warning could be 11796 1.1 jruoho incorrectly generated for names like "_SB" when the trailing 11797 1.1 jruoho underscore is not used in the original ASL. 11798 1.1 jruoho 11799 1.1 jruoho Fixed a problem where the reserved name check did not handle 11800 1.1 jruoho NamePaths with multiple NameSegs correctly. The first nameseg of 11801 1.1 jruoho the NamePath was examined instead of the last NameSeg. 11802 1.1 jruoho 11803 1.1 jruoho 11804 1.1 jruoho ---------------------------------------- 11805 1.1 jruoho 11806 1.1 jruoho 02 October 2002. Summary of changes for this release. 11807 1.1 jruoho 11808 1.1 jruoho 11809 1.1 jruoho 1) ACPI CA Core Subsystem version 20021002: 11810 1.1 jruoho 11811 1.1 jruoho Fixed a problem where a store/copy of a string to an existing 11812 1.1 jruoho string did not always set the string length properly in the String 11813 1.1 jruoho object. 11814 1.1 jruoho 11815 1.1 jruoho Fixed a reported problem with the ToString operator where the 11816 1.1 jruoho behavior was identical to the ToHexString operator instead of just 11817 1.1 jruoho simply converting a raw buffer to a string data type. 11818 1.1 jruoho 11819 1.1 jruoho Fixed a problem where CopyObject and the other "explicit" 11820 1.1 jruoho conversion operators were not updating the internal namespace node 11821 1.1 jruoho type as part of the store operation. 11822 1.1 jruoho 11823 1.1 jruoho Fixed a memory leak during implicit source operand conversion 11824 1.1 jruoho where the original object was not deleted if it was converted to a 11825 1.1 jruoho new object of a different type. 11826 1.1 jruoho 11827 1.1 jruoho Enhanced error messages for all problems associated with namespace 11828 1.1 jruoho lookups. Common procedure generates and prints the lookup name as 11829 1.1 jruoho well as the formatted status. 11830 1.1 jruoho 11831 1.1 jruoho Completed implementation of a new design for the Alias support 11832 1.1 jruoho within the namespace. The existing design did not handle the case 11833 1.1 jruoho where a new object was assigned to one of the two names due to the 11834 1.1 jruoho use of an explicit conversion operator, resulting in the two names 11835 1.1 jruoho pointing to two different objects. The new design simply points 11836 1.1 jruoho the Alias name to the original name node - not to the object. 11837 1.1 jruoho This results in a level of indirection that must be handled in the 11838 1.1 jruoho name resolution mechanism. 11839 1.1 jruoho 11840 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 11841 1.1 jruoho below. These are the code and data sizes for the acpica.lib 11842 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 11843 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 11844 1.1 jruoho version of the code includes the debug output trace mechanism and 11845 1.1 jruoho has a larger code and data size. Note that these values will vary 11846 1.1 jruoho depending on the efficiency of the compiler and the compiler 11847 1.1 jruoho options used during generation. 11848 1.1 jruoho 11849 1.1 jruoho Previous Release 11850 1.1 jruoho Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total 11851 1.1 jruoho Debug Version: 150.0K Code, 61.7K Data, 211.7K Total 11852 1.1 jruoho Current Release: 11853 1.1 jruoho Non-Debug Version: 70.7K Code, 8.6K Data, 79.3K Total 11854 1.1 jruoho Debug Version: 151.7K Code, 62.4K Data, 214.1K Total 11855 1.1 jruoho 11856 1.1 jruoho 11857 1.1 jruoho 2) Linux 11858 1.1 jruoho 11859 1.1 jruoho Initialize thermal driver's timer before it is used.

Summary of changes for this release. 11883 1.1 jruoho 11884 1.1 jruoho 11885 1.1 jruoho 1) ACPI CA Core Subsystem version 20020918: 11886 1.1 jruoho 11887 1.1 jruoho Fixed a reported problem with reference chaining (via the Index() 11888 1.1 jruoho and RefOf() operators) in the ObjectType() and SizeOf() operators. 11889 1.1 jruoho The definition of these operators includes the dereferencing of 11890 1.1 jruoho all chained references to return information on the base object. 11891 1.1 jruoho 11892 1.1 jruoho Fixed a problem with stores to indexed package elements - the 11893 1.1 jruoho existing code would not complete the store if an "implicit 11894 1.1 jruoho conversion" was not performed. In other words, if the existing 11895 1.1 jruoho object (package element) was to be replaced completely, the code 11896 1.1 jruoho didn't handle this case. 11897 1.1 jruoho 11898 1.1 jruoho Relaxed typechecking on the ASL "Scope" operator to allow the 11899 1.1 jruoho target name to refer to an object of type Integer, String, or 11900 1.1 jruoho Buffer, in addition to the scoping object types (Device, 11901 1.1 jruoho predefined Scopes, Processor, PowerResource, and ThermalZone.) 11902 1.1 jruoho This allows existing AML code that has workarounds for a bug in 11903 1.1 jruoho Windows to function properly. A warning is issued, however. This 11904 1.1 jruoho affects both the AML interpreter and the iASL compiler. Below is 11905 1.1 jruoho an example of this type of ASL code: 11906 1.1 jruoho 11907 1.1 jruoho Name(DEB,0x00) 11908 1.1 jruoho Scope(DEB) 11909 1.1 jruoho { 11910 1.1 jruoho 11911 1.1 jruoho Fixed some reported problems with 64-bit integer support in the 11912 1.1 jruoho local implementation of C library functions (clib.c) 11913 1.1 jruoho 11914 1.1 jruoho 11915 1.1 jruoho 2) Linux 11916 1.1 jruoho 11917 1.1 jruoho Use ACPI fix map region instead of IOAPIC region, since it is 11918 1.1 jruoho undefined in non-SMP. 11919 1.1 jruoho 11920 1.1 jruoho Ensure that the SCI has the proper polarity and trigger, even on 11921 1.1 jruoho systems that do not have an interrupt override entry in the MADT. 11922 1.1 jruoho 11923 1.1 jruoho 2.5 big driver reorganization (Pat Mochel) 11924 1.1 jruoho 11925 1.1 jruoho Use early table mapping code from acpitable.c (Andi Kleen) 11926 1.1 jruoho 11927 1.1 jruoho New blacklist entries (Andi Kleen) 11928 1.1 jruoho 11929 1.1 jruoho Blacklist improvements. Split blacklist code out into a separate 11930 1.1 jruoho file. Move checking the blacklist to very early. Previously, we 11931 1.1 jruoho would use ACPI tables, and then halfway through init, check the 11932 1.1 jruoho blacklist -- too late. Now, it's early enough to completely fall- 11933 1.1 jruoho back to non-ACPI. 11934 1.1 jruoho 11935 1.1 jruoho 11936 1.1 jruoho 3) iASL Compiler/Disassembler version 20020918: 11937 1.1 jruoho 11938 1.1 jruoho Fixed a problem where the typechecking code didn't know that an 11939 1.1 jruoho alias could point to a method. In other words, aliases were not 11940 1.1 jruoho being dereferenced during typechecking. 11941 1.1 jruoho 11942 1.1 jruoho 11943 1.1 jruoho ---------------------------------------- 11944 1.1 jruoho 29 August 2002. Summary of changes for this release. 11945 1.1 jruoho 11946 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020829: 11947 1.1 jruoho 11948 1.1 jruoho If the target of a Scope() operator already exists, it must be an 11949 1.1 jruoho object type that actually opens a scope -- such as a Device, 11950 1.1 jruoho Method, Scope, etc. This is a fatal runtime error. Similar error 11951 1.1 jruoho check has been added to the iASL compiler also. 11952 1.1 jruoho 11953 1.1 jruoho Tightened up the namespace load to disallow multiple names in the 11954 1.1 jruoho same scope. This previously was allowed if both objects were of 11955 1.1 jruoho the same type. (i.e., a lookup was the same as entering a new 11956 1.1 jruoho name). 11957 1.1 jruoho 11958 1.1 jruoho 11959 1.1 jruoho 2) Linux 11960 1.1 jruoho 11961 1.1 jruoho Ensure that the ACPI interrupt has the proper trigger and 11962 1.1 jruoho polarity. 11963 1.1 jruoho 11964 1.1 jruoho local_irq_disable is extraneous. (Matthew Wilcox) 11965 1.1 jruoho 11966 1.1 jruoho Make "acpi=off" actually do what it says, and not use the ACPI 11967 1.1 jruoho interpreter *or* the tables. 11968 1.1 jruoho 11969 1.1 jruoho Added arch-neutral support for parsing SLIT and SRAT tables (Kochi 11970 1.1 jruoho Takayoshi) 11971 1.1 jruoho 11972 1.1 jruoho 11973 1.1 jruoho 3) iASL Compiler/Disassembler Version 20020829: 11974 1.1 jruoho 11975 1.1 jruoho Implemented namepath optimization for name declarations. For 11976 1.1 jruoho example, a declaration like "Method (\_SB_.ABCD)" would get 11977 1.1 jruoho optimized to "Method (ABCD)" if the declaration is within the 11978 1.1 jruoho \_SB_ scope. This optimization is in addition to the named 11979 1.1 jruoho reference path optimization first released in the previous 11980 1.1 jruoho version. This would seem to complete all possible optimizations 11981 1.1 jruoho for namepaths within the ASL/AML. 11982 1.1 jruoho 11983 1.1 jruoho If the target of a Scope() operator already exists, it must be an 11984 1.1 jruoho object type that actually opens a scope -- such as a Device, 11985 1.1 jruoho Method, Scope, etc. 11986 1.1 jruoho 11987 1.1 jruoho Implemented a check and warning for unreachable code in the same 11988 1.1 jruoho block below a Return() statement. 11989 1.1 jruoho 11990 1.1 jruoho Fixed a problem where the listing file was not generated if the 11991 1.1 jruoho compiler aborted if the maximum error count was exceeded (200). 11992 1.1 jruoho 11993 1.1 jruoho Fixed a problem where the typechecking of method return values was 11994 1.1 jruoho broken. This includes the check for a return value when the 11995 1.1 jruoho method is invoked as a TermArg (a return value is expected.) 11996 1.1 jruoho 11997 1.1 jruoho Fixed a reported problem where EOF conditions during a quoted 11998 1.1 jruoho string or comment caused a fault. 11999 1.1 jruoho 12000 1.1 jruoho 12001 1.1 jruoho ---------------------------------------- 12002 1.1 jruoho 15 August 2002. Summary of changes for this release. 12003 1.1 jruoho 12004 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020815: 12005 1.1 jruoho 12006 1.1 jruoho Fixed a reported problem where a Store to a method argument that 12007 1.1 jruoho contains a reference did not perform the indirect store correctly. 12008 1.1 jruoho This problem was created during the conversion to the new 12009 1.1 jruoho reference object model - the indirect store to a method argument 12010 1.1 jruoho code was not updated to reflect the new model. 12011 1.1 jruoho 12012 1.1 jruoho Reworked the ACPI mode change code to better conform to ACPI 2.0, 12013 1.1 jruoho handle corner cases, and improve code legibility (Kochi Takayoshi) 12014 1.1 jruoho 12015 1.1 jruoho Fixed a problem with the pathname parsing for the carat (^) 12016 1.1 jruoho prefix. The heavy use of the carat operator by the new namepath 12017 1.1 jruoho optimization in the iASL compiler uncovered a problem with the AML 12018 1.1 jruoho interpreter handling of this prefix. In the case where one or 12019 1.1 jruoho more carats precede a single nameseg, the nameseg was treated as 12020 1.1 jruoho standalone and the search rule (to root) was inadvertently 12021 1.1 jruoho applied. This could cause both the iASL compiler and the 12022 1.1 jruoho interpreter to find the wrong object or to miss the error that 12023 1.1 jruoho should occur if the object does not exist at that exact pathname. 12024 1.1 jruoho 12025 1.1 jruoho Found and fixed the problem where the HP Pavilion DSDT would not 12026 1.1 jruoho load. This was a relatively minor tweak to the table loading code 12027 1.1 jruoho (a problem caused by the unexpected encounter with a method 12028 1.1 jruoho invocation not within a control method), but it does not solve the 12029 1.1 jruoho overall issue of the execution of AML code at the table level. 12030 1.1 jruoho This investigation is still ongoing. 12031 1.1 jruoho 12032 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12033 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12034 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12035 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12036 1.1 jruoho version of the code includes the debug output trace mechanism and 12037 1.1 jruoho has a larger code and data size. Note that these values will vary 12038 1.1 jruoho depending on the efficiency of the compiler and the compiler 12039 1.1 jruoho options used during generation. 12040 1.1 jruoho 12041 1.1 jruoho Previous Release 12042 1.1 jruoho Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 12043 1.1 jruoho Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 12044 1.1 jruoho Current Release: 12045 1.1 jruoho Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total 12046 1.1 jruoho Debug Version: 150.0K Code, 61.7K Data, 211.7K Total 12047 1.1 jruoho 12048 1.1 jruoho 12049 1.1 jruoho 2) Linux 12050 1.1 jruoho 12051 1.1 jruoho Remove redundant slab.h include (Brad Hards) 12052 1.1 jruoho 12053 1.1 jruoho Fix several bugs in thermal.c (Herbert Nachtnebel) 12054 1.1 jruoho 12055 1.1 jruoho Make CONFIG_ACPI_BOOT work properly (Pavel Machek) 12056 1.1 jruoho 12057 1.1 jruoho Change acpi_system_suspend to use updated irq functions (Pavel 12058 1.1 jruoho Machek) 12059 1.1 jruoho 12060 1.1 jruoho Export acpi_get_firmware_table (Matthew Wilcox) 12061 1.1 jruoho 12062 1.1 jruoho Use proper root proc entry for ACPI (Kochi Takayoshi) 12063 1.1 jruoho 12064 1.1 jruoho Fix early-boot table parsing (Bjorn Helgaas) 12065 1.1 jruoho 12066 1.1 jruoho 12067 1.1 jruoho 3) iASL Compiler/Disassembler 12068 1.1 jruoho 12069 1.1 jruoho Reworked the compiler options to make them more consistent and to 12070 1.1 jruoho use two-letter options where appropriate. We were running out of 12071 1.1 jruoho sensible letters. This may break some makefiles, so check the 12072 1.1 jruoho current options list by invoking the compiler with no parameters. 12073 1.1 jruoho 12074 1.1 jruoho Completed the design and implementation of the ASL namepath 12075 1.1 jruoho optimization option for the compiler. This option optimizes all 12076 1.1 jruoho references to named objects to the shortest possible path. The 12077 1.1 jruoho first attempt tries to utilize a single nameseg (4 characters) and 12078 1.1 jruoho the "search-to-root" algorithm used by the interpreter. If that 12079 1.1 jruoho cannot be used (because either the name is not in the search path 12080 1.1 jruoho or there is a conflict with another object with the same name), 12081 1.1 jruoho the pathname is optimized using the carat prefix (usually a 12082 1.1 jruoho shorter string than specifying the entire path from the root.) 12083 1.1 jruoho 12084 1.1 jruoho Implemented support to obtain the DSDT from the Windows registry 12085 1.1 jruoho (when the disassembly option is specified with no input file). 12086 1.1 jruoho Added this code as the implementation for AcpiOsTableOverride in 12087 1.1 jruoho the Windows OSL. Migrated the 16-bit code (used in the AcpiDump 12088 1.1 jruoho utility) to scan memory for the DSDT to the AcpiOsTableOverride 12089 1.1 jruoho function in the DOS OSL to make the disassembler truly OS 12090 1.1 jruoho independent. 12091 1.1 jruoho 12092 1.1 jruoho Implemented a new option to disassemble and compile in one step. 12093 1.1 jruoho When used without an input filename, this option will grab the 12094 1.1 jruoho DSDT from the local machine, disassemble it, and compile it in one 12095 1.1 jruoho step. 12096 1.1 jruoho 12097 1.1 jruoho Added a warning message for invalid escapes (a backslash followed 12098 1.1 jruoho by any character other than the allowable escapes). This catches 12099 1.1 jruoho the quoted string error "\_SB_" (which should be "\\_SB_" ). 12100 1.1 jruoho 12101 1.1 jruoho Also, there are numerous instances in the ACPI specification where 12102 1.1 jruoho this error occurs. 12103 1.1 jruoho 12104 1.1 jruoho Added a compiler option to disable all optimizations. This is 12105 1.1 jruoho basically the "compatibility mode" because by using this option, 12106 1.1 jruoho the AML code will come out exactly the same as other ASL 12107 1.1 jruoho compilers. 12108 1.1 jruoho 12109 1.1 jruoho Added error messages for incorrectly ordered dependent resource 12110 1.1 jruoho functions. This includes: missing EndDependentFn macro at end of 12111 1.1 jruoho dependent resource list, nested dependent function macros (both 12112 1.1 jruoho start and end), and missing StartDependentFn macro. These are 12113 1.1 jruoho common errors that should be caught at compile time. 12114 1.1 jruoho 12115 1.1 jruoho Implemented _OSI support for the disassembler and compiler. _OSI 12116 1.1 jruoho must be included in the namespace for proper disassembly (because 12117 1.1 jruoho the disassembler must know the number of arguments.) 12118 1.1 jruoho 12119 1.1 jruoho Added an "optimization" message type that is optional (off by 12120 1.1 jruoho default). This message is used for all optimizations - including 12121 1.1 jruoho constant folding, integer optimization, and namepath optimization. 12122 1.1 jruoho 12123 1.1 jruoho ---------------------------------------- 12124 1.1 jruoho 25 July 2002. Summary of changes for this release. 12125 1.1 jruoho 12126 1.1 jruoho 12127 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020725: 12128 1.1 jruoho 12129 1.1 jruoho The AML Disassembler has been enhanced to produce compilable ASL 12130 1.1 jruoho code and has been integrated into the iASL compiler (see below) as 12131 1.1 jruoho well as the single-step disassembly for the AML debugger and the 12132 1.1 jruoho disassembler for the AcpiDump utility. All ACPI 2.0A opcodes, 12133 1.1 jruoho resource templates and macros are fully supported. The 12134 1.1 jruoho disassembler has been tested on over 30 different AML files, 12135 1.1 jruoho producing identical AML when the resulting disassembled ASL file 12136 1.1 jruoho is recompiled with the same ASL compiler. 12137 1.1 jruoho 12138 1.1 jruoho Modified the Resource Manager to allow zero interrupts and zero 12139 1.1 jruoho dma channels during the GetCurrentResources call. This was 12140 1.1 jruoho causing problems on some platforms. 12141 1.1 jruoho 12142 1.1 jruoho Added the AcpiOsRedirectOutput interface to the OSL to simplify 12143 1.1 jruoho output redirection for the AcpiOsPrintf and AcpiOsVprintf 12144 1.1 jruoho interfaces. 12145 1.1 jruoho 12146 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12147 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12148 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12149 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12150 1.1 jruoho version of the code includes the debug output trace mechanism and 12151 1.1 jruoho has a larger code and data size. Note that these values will vary 12152 1.1 jruoho depending on the efficiency of the compiler and the compiler 12153 1.1 jruoho options used during generation. 12154 1.1 jruoho 12155 1.1 jruoho Previous Release 12156 1.1 jruoho Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 12157 1.1 jruoho Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 12158 1.1 jruoho Current Release: 12159 1.1 jruoho Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 12160 1.1 jruoho Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 12161 1.1 jruoho 12162 1.1 jruoho 12163 1.1 jruoho 2) Linux 12164 1.1 jruoho 12165 1.1 jruoho Fixed a panic in the EC driver (Dominik Brodowski) 12166 1.1 jruoho 12167 1.1 jruoho Implemented checksum of the R/XSDT itself during Linux table scan 12168 1.1 jruoho (Richard Schaal) 12169 1.1 jruoho 12170 1.1 jruoho 12171 1.1 jruoho 3) iASL compiler 12172 1.1 jruoho 12173 1.1 jruoho The AML disassembler is integrated into the compiler. The "-d" 12174 1.1 jruoho option invokes the disassembler to completely disassemble an 12175 1.1 jruoho input AML file, producing as output a text ASL file with the 12176 1.1 jruoho extension ".dsl" (to avoid name collisions with existing .asl 12177 1.1 jruoho source files.) A future enhancement will allow the disassembler 12178 1.1 jruoho to obtain the BIOS DSDT from the registry under Windows. 12179 1.1 jruoho 12180 1.1 jruoho Fixed a problem with the VendorShort and VendorLong resource 12181 1.1 jruoho descriptors where an invalid AML sequence was created. 12182 1.1 jruoho 12183 1.1 jruoho Implemented a fix for BufferData term in the ASL parser. It was 12184 1.1 jruoho inadvertently defined twice, allowing invalid syntax to pass and 12185 1.1 jruoho causing reduction conflicts. 12186 1.1 jruoho 12187 1.1 jruoho Fixed a problem where the Ones opcode could get converted to a 12188 1.1 jruoho value of zero if "Ones" was used where a byte, word or dword value 12189 1.1 jruoho was expected. The 64-bit value is now truncated to the correct 12190 1.1 jruoho size with the correct value. 12191 1.1 jruoho 12192 1.1 jruoho 12193 1.1 jruoho 12194 1.1 jruoho ---------------------------------------- 12195 1.1 jruoho 02 July 2002. Summary of changes for this release. 12196 1.1 jruoho 12197 1.1 jruoho 12198 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020702: 12199 1.1 jruoho 12200 1.1 jruoho The Table Manager code has been restructured to add several new 12201 1.1 jruoho features. Tables that are not required by the core subsystem 12202 1.1 jruoho (other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer 12203 1.1 jruoho validated in any way and are returned from AcpiGetFirmwareTable if 12204 1.1 jruoho requested. The AcpiOsTableOverride interface is now called for 12205 1.1 jruoho each table that is loaded by the subsystem in order to allow the 12206 1.1 jruoho host to override any table it chooses. Previously, only the DSDT 12207 1.1 jruoho could be overridden. Added one new files, tbrsdt.c and 12208 1.1 jruoho tbgetall.c. 12209 1.1 jruoho 12210 1.1 jruoho Fixed a problem with the conversion of internal package objects to 12211 1.1 jruoho external objects (when a package is returned from a control 12212 1.1 jruoho method.) The return buffer length was set to zero instead of the 12213 1.1 jruoho proper length of the package object. 12214 1.1 jruoho 12215 1.1 jruoho Fixed a reported problem with the use of the RefOf and DeRefOf 12216 1.1 jruoho operators when passing reference arguments to control methods. A 12217 1.1 jruoho new type of Reference object is used internally for references 12218 1.1 jruoho produced by the RefOf operator. 12219 1.1 jruoho 12220 1.1 jruoho Added additional error messages in the Resource Manager to explain 12221 1.1 jruoho AE_BAD_DATA errors when they occur during resource parsing. 12222 1.1 jruoho 12223 1.1 jruoho Split the AcpiEnableSubsystem into two primitives to enable a 12224 1.1 jruoho finer granularity initialization sequence. These two calls should 12225 1.1 jruoho be called in this order: AcpiEnableSubsystem (flags), 12226 1.1 jruoho AcpiInitializeObjects (flags). The flags parameter remains the 12227 1.1 jruoho same. 12228 1.1 jruoho 12229 1.1 jruoho 12230 1.1 jruoho 2) Linux 12231 1.1 jruoho 12232 1.1 jruoho Updated the ACPI utilities module to understand the new style of 12233 1.1 jruoho fully resolved package objects that are now returned from the core 12234 1.1 jruoho subsystem. This eliminates errors of the form: 12235 1.1 jruoho 12236 1.1 jruoho ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT] 12237 1.1 jruoho acpi_utils-0430 [145] acpi_evaluate_reference: 12238 1.1 jruoho Invalid element in package (not a device reference) 12239 1.1 jruoho 12240 1.1 jruoho The method evaluation utility uses the new buffer allocation 12241 1.1 jruoho scheme instead of calling AcpiEvaluate Object twice. 12242 1.1 jruoho 12243 1.1 jruoho Added support for ECDT. This allows the use of the Embedded 12244 1.1 jruoho 12245 1.1 jruoho Controller before the namespace has been fully initialized, which 12246 1.1 jruoho is necessary for ACPI 2.0 support, and for some laptops to 12247 1.1 jruoho initialize properly. (Laptops using ECDT are still rare, so only 12248 1.1 jruoho limited testing was performed of the added functionality.) 12249 1.1 jruoho 12250 1.1 jruoho Fixed memory leaks in the EC driver. 12251 1.1 jruoho 12252 1.1 jruoho Eliminated a brittle code structure in acpi_bus_init(). 12253 1.1 jruoho 12254 1.1 jruoho Eliminated the acpi_evaluate() helper function in utils.c. It is 12255 1.1 jruoho no longer needed since acpi_evaluate_object can optionally 12256 1.1 jruoho allocate memory for the return object. 12257 1.1 jruoho 12258 1.1 jruoho Implemented fix for keyboard hang when getting battery readings on 12259 1.1 jruoho some systems (Stephen White) 12260 1.1 jruoho 12261 1.1 jruoho PCI IRQ routing update (Dominik Brodowski) 12262 1.1 jruoho 12263 1.1 jruoho Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC 12264 1.1 jruoho support 12265 1.1 jruoho 12266 1.1 jruoho ---------------------------------------- 12267 1.1 jruoho 11 June 2002. Summary of changes for this release. 12268 1.1 jruoho 12269 1.1 jruoho 12270 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020611: 12271 1.1 jruoho 12272 1.1 jruoho Fixed a reported problem where constants such as Zero and One 12273 1.1 jruoho appearing within _PRT packages were not handled correctly within 12274 1.1 jruoho the resource manager code. Originally reported against the ASL 12275 1.1 jruoho compiler because the code generator now optimizes integers to 12276 1.1 jruoho their minimal AML representation (i.e. AML constants if possible.) 12277 1.1 jruoho The _PRT code now handles all AML constant opcodes correctly 12278 1.1 jruoho (Zero, One, Ones, Revision). 12279 1.1 jruoho 12280 1.1 jruoho Fixed a problem with the Concatenate operator in the AML 12281 1.1 jruoho interpreter where a buffer result object was incorrectly marked as 12282 1.1 jruoho not fully evaluated, causing a run-time error of AE_AML_INTERNAL. 12283 1.1 jruoho 12284 1.1 jruoho All package sub-objects are now fully resolved before they are 12285 1.1 jruoho returned from the external ACPI interfaces. This means that name 12286 1.1 jruoho strings are resolved to object handles, and constant operators 12287 1.1 jruoho (Zero, One, Ones, Revision) are resolved to Integers. 12288 1.1 jruoho 12289 1.1 jruoho Implemented immediate resolution of the AML Constant opcodes 12290 1.1 jruoho (Zero, One, Ones, Revision) to Integer objects upon detection 12291 1.1 jruoho within the AML stream. This has simplified and reduced the 12292 1.1 jruoho generated code size of the subsystem by eliminating about 10 12293 1.1 jruoho switch statements for these constants (which previously were 12294 1.1 jruoho contained in Reference objects.) The complicating issues are that 12295 1.1 jruoho the Zero opcode is used as a "placeholder" for unspecified 12296 1.1 jruoho optional target operands and stores to constants are defined to be 12297 1.1 jruoho no-ops. 12298 1.1 jruoho 12299 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12300 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12301 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12302 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12303 1.1 jruoho version of the code includes the debug output trace mechanism and 12304 1.1 jruoho has a larger code and data size. Note that these values will vary 12305 1.1 jruoho depending on the efficiency of the compiler and the compiler 12306 1.1 jruoho options used during generation. 12307 1.1 jruoho 12308 1.1 jruoho Previous Release 12309 1.1 jruoho Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total 12310 1.1 jruoho Debug Version: 143.8K Code, 58.8K Data, 202.6K Total 12311 1.1 jruoho Current Release: 12312 1.1 jruoho Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 12313 1.1 jruoho Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 12314 1.1 jruoho 12315 1.1 jruoho 12316 1.1 jruoho 2) Linux 12317 1.1 jruoho 12318 1.1 jruoho 12319 1.1 jruoho Added preliminary support for obtaining _TRA data for PCI root 12320 1.1 jruoho bridges (Bjorn Helgaas). 12321 1.1 jruoho 12322 1.1 jruoho 12323 1.1 jruoho 3) iASL Compiler Version X2046: 12324 1.1 jruoho 12325 1.1 jruoho Fixed a problem where the "_DDN" reserved name was defined to be a 12326 1.1 jruoho control method with one argument. There are no arguments, and 12327 1.1 jruoho _DDN does not have to be a control method. 12328 1.1 jruoho 12329 1.1 jruoho Fixed a problem with the Linux version of the compiler where the 12330 1.1 jruoho source lines printed with error messages were the wrong lines. 12331 1.1 jruoho This turned out to be the "LF versus CR/LF" difference between 12332 1.1 jruoho Windows and Unix. This appears to be the longstanding issue 12333 1.1 jruoho concerning listing output and error messages. 12334 1.1 jruoho 12335 1.1 jruoho Fixed a problem with the Linux version of compiler where opcode 12336 1.1 jruoho names within error messages were wrong. This was caused by a 12337 1.1 jruoho slight difference in the output of the Flex tool on Linux versus 12338 1.1 jruoho Windows. 12339 1.1 jruoho 12340 1.1 jruoho Fixed a problem with the Linux compiler where the hex output files 12341 1.1 jruoho contained some garbage data caused by an internal buffer overrun. 12342 1.1 jruoho 12343 1.1 jruoho 12344 1.1 jruoho ---------------------------------------- 12345 1.1 jruoho 17 May 2002. Summary of changes for this release. 12346 1.1 jruoho 12347 1.1 jruoho 12348 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020517: 12349 1.1 jruoho 12350 1.1 jruoho Implemented a workaround to an BIOS bug discovered on the HP 12351 1.1 jruoho OmniBook where the FADT revision number and the table size are 12352 1.1 jruoho inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The new 12353 1.1 jruoho behavior is to fallback to using only the ACPI 1.0 fields of the 12354 1.1 jruoho FADT if the table is too small to be a ACPI 2.0 table as claimed 12355 1.1 jruoho by the revision number. Although this is a BIOS bug, this is a 12356 1.1 jruoho case where the workaround is simple enough and with no side 12357 1.1 jruoho effects, so it seemed prudent to add it. A warning message is 12358 1.1 jruoho issued, however. 12359 1.1 jruoho 12360 1.1 jruoho Implemented minimum size checks for the fixed-length ACPI tables - 12361 1.1 jruoho - the FADT and FACS, as well as consistency checks between the 12362 1.1 jruoho revision number and the table size. 12363 1.1 jruoho 12364 1.1 jruoho Fixed a reported problem in the table override support where the 12365 1.1 jruoho new table pointer was incorrectly treated as a physical address 12366 1.1 jruoho instead of a logical address. 12367 1.1 jruoho 12368 1.1 jruoho Eliminated the use of the AE_AML_ERROR exception and replaced it 12369 1.1 jruoho with more descriptive codes. 12370 1.1 jruoho 12371 1.1 jruoho Fixed a problem where an exception would occur if an ASL Field was 12372 1.1 jruoho defined with no named Field Units underneath it (used by some 12373 1.1 jruoho index fields). 12374 1.1 jruoho 12375 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12376 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12377 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12378 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12379 1.1 jruoho version of the code includes the debug output trace mechanism and 12380 1.1 jruoho has a larger code and data size. Note that these values will vary 12381 1.1 jruoho depending on the efficiency of the compiler and the compiler 12382 1.1 jruoho options used during generation. 12383 1.1 jruoho 12384 1.1 jruoho Previous Release 12385 1.1 jruoho Non-Debug Version: 68.8K Code, 7.1K Data, 75.9K Total 12386 1.1 jruoho Debug Version: 142.9K Code, 58.4K Data, 201.3K Total 12387 1.1 jruoho Current Release: 12388 1.1 jruoho Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total 12389 1.1 jruoho Debug Version: 143.8K Code, 58.8K Data, 202.6K Total 12390 1.1 jruoho 12391 1.1 jruoho 12392 1.1 jruoho 12393 1.1 jruoho 2) Linux 12394 1.1 jruoho 12395 1.1 jruoho Much work done on ACPI init (MADT and PCI IRQ routing support). 12396 1.1 jruoho (Paul D. and Dominik Brodowski) 12397 1.1 jruoho 12398 1.1 jruoho Fix PCI IRQ-related panic on boot (Sam Revitch) 12399 1.1 jruoho 12400 1.1 jruoho Set BM_ARB_DIS when entering a sleep state (Ducrot Bruno) 12401 1.1 jruoho 12402 1.1 jruoho Fix "MHz" typo (Dominik Brodowski) 12403 1.1 jruoho 12404 1.1 jruoho Fix RTC year 2000 issue (Dominik Brodowski) 12405 1.1 jruoho 12406 1.1 jruoho Preclude multiple button proc entries (Eric Brunet) 12407 1.1 jruoho 12408 1.1 jruoho Moved arch-specific code out of include/platform/aclinux.h 12409 1.1 jruoho 12410 1.1 jruoho 3) iASL Compiler Version X2044: 12411 1.1 jruoho 12412 1.1 jruoho Implemented error checking for the string used in the EISAID macro 12413 1.1 jruoho (Usually used in the definition of the _HID object.) The code now 12414 1.1 jruoho strictly enforces the PnP format - exactly 7 characters, 3 12415 1.1 jruoho uppercase letters and 4 hex digits. 12416 1.1 jruoho 12417 1.1 jruoho If a raw string is used in the definition of the _HID object 12418 1.1 jruoho (instead of the EISAID macro), the string must contain all 12419 1.1 jruoho alphanumeric characters (e.g., "*PNP0011" is not allowed because 12420 1.1 jruoho of the asterisk.) 12421 1.1 jruoho 12422 1.1 jruoho Implemented checking for invalid use of ACPI reserved names for 12423 1.1 jruoho most of the name creation operators (Name, Device, Event, Mutex, 12424 1.1 jruoho OperationRegion, PowerResource, Processor, and ThermalZone.) 12425 1.1 jruoho Previously, this check was only performed for control methods. 12426 1.1 jruoho 12427 1.1 jruoho Implemented an additional check on the Name operator to emit an 12428 1.1 jruoho error if a reserved name that must be implemented in ASL as a 12429 1.1 jruoho control method is used. We know that a reserved name must be a 12430 1.1 jruoho method if it is defined with input arguments. 12431 1.1 jruoho 12432 1.1 jruoho The warning emitted when a namespace object reference is not found 12433 1.1 jruoho during the cross reference phase has been changed into an error. 12434 1.1 jruoho The "External" directive should be used for names defined in other 12435 1.1 jruoho modules. 12436 1.1 jruoho 12437 1.1 jruoho 12438 1.1 jruoho 4) Tools and Utilities 12439 1.1 jruoho 12440 1.1 jruoho The 16-bit tools (adump16 and aexec16) have been regenerated and 12441 1.1 jruoho tested. 12442 1.1 jruoho 12443 1.1 jruoho Fixed a problem with the output of both acpidump and adump16 where 12444 1.1 jruoho the indentation of closing parentheses and brackets was not 12445 1.1 jruoho 12446 1.1 jruoho aligned properly with the parent block. 12447 1.1 jruoho 12448 1.1 jruoho 12449 1.1 jruoho ---------------------------------------- 12450 1.1 jruoho 03 May 2002. Summary of changes for this release. 12451 1.1 jruoho 12452 1.1 jruoho 12453 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020503: 12454 1.1 jruoho 12455 1.1 jruoho Added support a new OSL interface that allows the host operating 12456 1.1 jruoho 12457 1.1 jruoho system software to override the DSDT found in the firmware - 12458 1.1 jruoho AcpiOsTableOverride. With this interface, the OSL can examine the 12459 1.1 jruoho version of the firmware DSDT and replace it with a different one 12460 1.1 jruoho if desired. 12461 1.1 jruoho 12462 1.1 jruoho Added new external interfaces for accessing ACPI registers from 12463 1.1 jruoho device drivers and other system software - AcpiGetRegister and 12464 1.1 jruoho AcpiSetRegister. This was simply an externalization of the 12465 1.1 jruoho existing AcpiHwBitRegister interfaces. 12466 1.1 jruoho 12467 1.1 jruoho Fixed a regression introduced in the previous build where the 12468 1.1 jruoho ASL/AML CreateField operator always returned an error, 12469 1.1 jruoho "destination must be a NS Node". 12470 1.1 jruoho 12471 1.1 jruoho Extended the maximum time (before failure) to successfully enable 12472 1.1 jruoho ACPI mode to 3 seconds. 12473 1.1 jruoho 12474 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12475 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12476 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12477 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12478 1.1 jruoho version of the code includes the debug output trace mechanism and 12479 1.1 jruoho has a larger code and data size. Note that these values will vary 12480 1.1 jruoho depending on the efficiency of the compiler and the compiler 12481 1.1 jruoho options used during generation. 12482 1.1 jruoho 12483 1.1 jruoho Previous Release 12484 1.1 jruoho Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total 12485 1.1 jruoho Debug Version: 142.4K Code, 58.3K Data, 200.7K Total 12486 1.1 jruoho Current Release: 12487 1.1 jruoho Non-Debug Version: 68.8K Code, 7.1K Data, 75.9K Total 12488 1.1 jruoho Debug Version: 142.9K Code, 58.4K Data, 201.3K Total 12489 1.1 jruoho 12490 1.1 jruoho 12491 1.1 jruoho 2) Linux 12492 1.1 jruoho 12493 1.1 jruoho Enhanced ACPI init code for SMP. We are now fully MPS and $PIR- 12494 1.1 jruoho free. While 3 out of 4 of our in-house systems work fine, the last 12495 1.1 jruoho one still hangs when testing the LAPIC timer. 12496 1.1 jruoho 12497 1.1 jruoho Renamed many files in 2.5 kernel release to omit "acpi_" from the 12498 1.1 jruoho name. 12499 1.1 jruoho 12500 1.1 jruoho Added warning on boot for Presario 711FR. 12501 1.1 jruoho 12502 1.1 jruoho Sleep improvements (Pavel Machek) 12503 1.1 jruoho 12504 1.1 jruoho ACPI can now be built without CONFIG_PCI enabled. 12505 1.1 jruoho 12506 1.1 jruoho IA64: Fixed memory map functions (JI Lee) 12507 1.1 jruoho 12508 1.1 jruoho 12509 1.1 jruoho 3) iASL Compiler Version X2043: 12510 1.1 jruoho 12511 1.1 jruoho Added support to allow the compiler to be integrated into the MS 12512 1.1 jruoho VC++ development environment for one-button compilation of single 12513 1.1 jruoho files or entire projects -- with error-to-source-line mapping. 12514 1.1 jruoho 12515 1.1 jruoho Implemented support for compile-time constant folding for the 12516 1.1 jruoho Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0 12517 1.1 jruoho specification. This allows the ASL writer to use expressions 12518 1.1 jruoho instead of Integer/Buffer/String constants in terms that must 12519 1.1 jruoho evaluate to constants at compile time and will also simplify the 12520 1.1 jruoho emitted AML in any such sub-expressions that can be folded 12521 1.1 jruoho (evaluated at compile-time.) This increases the size of the 12522 1.1 jruoho compiler significantly because a portion of the ACPI CA AML 12523 1.1 jruoho interpreter is included within the compiler in order to pre- 12524 1.1 jruoho evaluate constant expressions. 12525 1.1 jruoho 12526 1.1 jruoho 12527 1.1 jruoho Fixed a problem with the "Unicode" ASL macro that caused the 12528 1.1 jruoho compiler to fault. (This macro is used in conjunction with the 12529 1.1 jruoho _STR reserved name.) 12530 1.1 jruoho 12531 1.1 jruoho Implemented an AML opcode optimization to use the Zero, One, and 12532 1.1 jruoho Ones opcodes where possible to further reduce the size of integer 12533 1.1 jruoho constants and thus reduce the overall size of the generated AML 12534 1.1 jruoho code. 12535 1.1 jruoho 12536 1.1 jruoho Implemented error checking for new reserved terms for ACPI version 12537 1.1 jruoho 2.0A. 12538 1.1 jruoho 12539 1.1 jruoho Implemented the -qr option to display the current list of ACPI 12540 1.1 jruoho reserved names known to the compiler. 12541 1.1 jruoho 12542 1.1 jruoho Implemented the -qc option to display the current list of ASL 12543 1.1 jruoho operators that are allowed within constant expressions and can 12544 1.1 jruoho therefore be folded at compile time if the operands are constants. 12545 1.1 jruoho 12546 1.1 jruoho 12547 1.1 jruoho 4) Documentation 12548 1.1 jruoho 12549 1.1 jruoho Updated the Programmer's Reference for new interfaces, data types, 12550 1.1 jruoho and memory allocation model options. 12551 1.1 jruoho 12552 1.1 jruoho Updated the iASL Compiler User Reference to apply new format and 12553 1.1 jruoho add information about new features and options. 12554 1.1 jruoho 12555 1.1 jruoho ---------------------------------------- 12556 1.1 jruoho 19 April 2002. Summary of changes for this release. 12557 1.1 jruoho 12558 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020419: 12559 1.1 jruoho 12560 1.1 jruoho The source code base for the Core Subsystem has been completely 12561 1.1 jruoho cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit 12562 1.1 jruoho versions. The Lint option files used are included in the 12563 1.1 jruoho /acpi/generate/lint directory. 12564 1.1 jruoho 12565 1.1 jruoho Implemented enhanced status/error checking across the entire 12566 1.1 jruoho Hardware manager subsystem. Any hardware errors (reported from 12567 1.1 jruoho the OSL) are now bubbled up and will abort a running control 12568 1.1 jruoho method. 12569 1.1 jruoho 12570 1.1 jruoho 12571 1.1 jruoho Fixed a problem where the per-ACPI-table integer width (32 or 64) 12572 1.1 jruoho was stored only with control method nodes, causing a fault when 12573 1.1 jruoho non-control method code was executed during table loading. The 12574 1.1 jruoho solution implemented uses a global variable to indicate table 12575 1.1 jruoho width across the entire ACPI subsystem. Therefore, ACPI CA does 12576 1.1 jruoho not support mixed integer widths across different ACPI tables 12577 1.1 jruoho (DSDT, SSDT). 12578 1.1 jruoho 12579 1.1 jruoho Fixed a problem where NULL extended fields (X fields) in an ACPI 12580 1.1 jruoho 2.0 ACPI FADT caused the table load to fail. Although the 12581 1.1 jruoho existing ACPI specification is a bit fuzzy on this topic, the new 12582 1.1 jruoho behavior is to fall back on a ACPI 1.0 field if the corresponding 12583 1.1 jruoho ACPI 2.0 X field is zero (even though the table revision indicates 12584 1.1 jruoho a full ACPI 2.0 table.) The ACPI specification will be updated to 12585 1.1 jruoho clarify this issue. 12586 1.1 jruoho 12587 1.1 jruoho Fixed a problem with the SystemMemory operation region handler 12588 1.1 jruoho where memory was always accessed byte-wise even if the AML- 12589 1.1 jruoho specified access width was larger than a byte. This caused 12590 1.1 jruoho problems on systems with memory-mapped I/O. Memory is now 12591 1.1 jruoho accessed with the width specified. On systems that do not support 12592 1.1 jruoho non-aligned transfers, a check is made to guarantee proper address 12593 1.1 jruoho alignment before proceeding in order to avoid an AML-caused 12594 1.1 jruoho alignment fault within the kernel. 12595 1.1 jruoho 12596 1.1 jruoho 12597 1.1 jruoho Fixed a problem with the ExtendedIrq resource where only one byte 12598 1.1 jruoho of the 4-byte Irq field was extracted. 12599 1.1 jruoho 12600 1.1 jruoho Fixed the AcpiExDigitsNeeded() procedure to support _UID. This 12601 1.1 jruoho function was out of date and required a rewrite. 12602 1.1 jruoho 12603 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12604 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12605 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12606 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12607 1.1 jruoho version of the code includes the debug output trace mechanism and 12608 1.1 jruoho has a larger code and data size. Note that these values will vary 12609 1.1 jruoho depending on the efficiency of the compiler and the compiler 12610 1.1 jruoho options used during generation. 12611 1.1 jruoho 12612 1.1 jruoho Previous Release 12613 1.1 jruoho Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total 12614 1.1 jruoho Debug Version: 139.8K Code, 57.4K Data, 197.2K Total 12615 1.1 jruoho Current Release: 12616 1.1 jruoho Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total 12617 1.1 jruoho Debug Version: 142.4K Code, 58.3K Data, 200.7K Total 12618 1.1 jruoho 12619 1.1 jruoho 12620 1.1 jruoho 2) Linux 12621 1.1 jruoho 12622 1.1 jruoho PCI IRQ routing fixes (Dominik Brodowski) 12623 1.1 jruoho 12624 1.1 jruoho 12625 1.1 jruoho 3) iASL Compiler Version X2042: 12626 1.1 jruoho 12627 1.1 jruoho Implemented an additional compile-time error check for a field 12628 1.1 jruoho unit whose size + minimum access width would cause a run-time 12629 1.1 jruoho access beyond the end-of-region. Previously, only the field size 12630 1.1 jruoho itself was checked. 12631 1.1 jruoho 12632 1.1 jruoho The Core subsystem and iASL compiler now share a common parse 12633 1.1 jruoho object in preparation for compile-time evaluation of the type 12634 1.1 jruoho 3/4/5 ASL operators. 12635 1.1 jruoho 12636 1.1 jruoho 12637 1.1 jruoho ---------------------------------------- 12638 1.1 jruoho Summary of changes for this release: 03_29_02 12639 1.1 jruoho 12640 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020329: 12641 1.1 jruoho 12642 1.1 jruoho Implemented support for late evaluation of TermArg operands to 12643 1.1 jruoho Buffer and Package objects. This allows complex expressions to be 12644 1.1 jruoho used in the declarations of these object types. 12645 1.1 jruoho 12646 1.1 jruoho Fixed an ACPI 1.0 compatibility issue when reading Fields. In ACPI 12647 1.1 jruoho 1.0, if the field was larger than 32 bits, it was returned as a 12648 1.1 jruoho buffer - otherwise it was returned as an integer. In ACPI 2.0, 12649 1.1 jruoho the field is returned as a buffer only if the field is larger than 12650 1.1 jruoho 64 bits. The TableRevision is now considered when making this 12651 1.1 jruoho conversion to avoid incompatibility with existing ASL code. 12652 1.1 jruoho 12653 1.1 jruoho Implemented logical addressing for AcpiOsGetRootPointer. This 12654 1.1 jruoho allows an RSDP with either a logical or physical address. With 12655 1.1 jruoho this support, the host OS can now override all ACPI tables with 12656 1.1 jruoho one logical RSDP. Includes implementation of "typed" pointer 12657 1.1 jruoho support to allow a common data type for both physical and logical 12658 1.1 jruoho pointers internally. This required a change to the 12659 1.1 jruoho AcpiOsGetRootPointer interface. 12660 1.1 jruoho 12661 1.1 jruoho Implemented the use of ACPI 2.0 Generic Address Structures for all 12662 1.1 jruoho GPE, Fixed Event, and PM Timer I/O. This allows the use of memory 12663 1.1 jruoho mapped I/O for these ACPI features. 12664 1.1 jruoho 12665 1.1 jruoho Initialization now ignores not only non-required tables (All 12666 1.1 jruoho tables other than the FADT, FACS, DSDT, and SSDTs), but also does 12667 1.1 jruoho not validate the table headers of unrecognized tables. 12668 1.1 jruoho 12669 1.1 jruoho Fixed a problem where a notify handler could only be 12670 1.1 jruoho installed/removed on an object of type Device. All "notify" 12671 1.1 jruoho 12672 1.1 jruoho objects are now supported -- Devices, Processor, Power, and 12673 1.1 jruoho Thermal. 12674 1.1 jruoho 12675 1.1 jruoho Removed most verbosity from the ACPI_DB_INFO debug level. Only 12676 1.1 jruoho critical information is returned when this debug level is enabled. 12677 1.1 jruoho 12678 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12679 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12680 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12681 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12682 1.1 jruoho version of the code includes the debug output trace mechanism and 12683 1.1 jruoho has a larger code and data size. Note that these values will vary 12684 1.1 jruoho depending on the efficiency of the compiler and the compiler 12685 1.1 jruoho options used during generation. 12686 1.1 jruoho 12687 1.1 jruoho Previous Release 12688 1.1 jruoho Non-Debug Version: 65.4K Code, 6.2K Data, 71.6K Total 12689 1.1 jruoho Debug Version: 138.0K Code, 56.6K Data, 194.6K Total 12690 1.1 jruoho Current Release: 12691 1.1 jruoho Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total 12692 1.1 jruoho Debug Version: 139.8K Code, 57.4K Data, 197.2K Total 12693 1.1 jruoho 12694 1.1 jruoho 12695 1.1 jruoho 2) Linux: 12696 1.1 jruoho 12697 1.1 jruoho The processor driver (acpi_processor.c) now fully supports ACPI 12698 1.1 jruoho 2.0-based processor performance control (e.g. Intel(R) 12699 1.1 jruoho SpeedStep(TM) technology) Note that older laptops that only have 12700 1.1 jruoho the Intel "applet" interface are not supported through this. The 12701 1.1 jruoho 'limit' and 'performance' interface (/proc) are fully functional. 12702 1.1 jruoho [Note that basic policy for controlling performance state 12703 1.1 jruoho transitions will be included in the next version of ospmd.] The 12704 1.1 jruoho idle handler was modified to more aggressively use C2, and PIIX4 12705 1.1 jruoho errata handling underwent a complete overhaul (big thanks to 12706 1.1 jruoho Dominik Brodowski). 12707 1.1 jruoho 12708 1.1 jruoho Added support for ACPI-PCI device binding (acpi_pci_root.c). _ADR- 12709 1.1 jruoho based devices in the ACPI namespace are now dynamically bound 12710 1.1 jruoho (associated) with their PCI counterparts (e.g. PCI1->01:00.0). 12711 1.1 jruoho This allows, among other things, ACPI to resolve bus numbers for 12712 1.1 jruoho subordinate PCI bridges. 12713 1.1 jruoho 12714 1.1 jruoho Enhanced PCI IRQ routing to get the proper bus number for _PRT 12715 1.1 jruoho entries defined underneath PCI bridges. 12716 1.1 jruoho 12717 1.1 jruoho Added IBM 600E to bad bios list due to invalid _ADR value for 12718 1.1 jruoho PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ routing. 12719 1.1 jruoho 12720 1.1 jruoho In the process of adding full MADT support (e.g. IOAPIC) for IA32 12721 1.1 jruoho (acpi.c, mpparse.c) -- stay tuned. 12722 1.1 jruoho 12723 1.1 jruoho Added back visual differentiation between fixed-feature and 12724 1.1 jruoho control-method buttons in dmesg. Buttons are also subtyped (e.g. 12725 1.1 jruoho button/power/PWRF) to simplify button identification. 12726 1.1 jruoho 12727 1.1 jruoho We no longer use -Wno-unused when compiling debug. Please ignore 12728 1.1 jruoho any "_THIS_MODULE defined but not used" messages. 12729 1.1 jruoho 12730 1.1 jruoho Can now shut down the system using "magic sysrq" key. 12731 1.1 jruoho 12732 1.1 jruoho 12733 1.1 jruoho 3) iASL Compiler version 2041: 12734 1.1 jruoho 12735 1.1 jruoho Fixed a problem where conversion errors for hex/octal/decimal 12736 1.1 jruoho constants were not reported. 12737 1.1 jruoho 12738 1.1 jruoho Implemented a fix for the General Register template Address field. 12739 1.1 jruoho This field was 8 bits when it should be 64. 12740 1.1 jruoho 12741 1.1 jruoho Fixed a problem where errors/warnings were no longer being emitted 12742 1.1 jruoho within the listing output file. 12743 1.1 jruoho 12744 1.1 jruoho Implemented the ACPI 2.0A restriction on ACPI Table Signatures to 12745 1.1 jruoho exactly 4 characters, alphanumeric only. 12746 1.1 jruoho 12747 1.1 jruoho 12748 1.1 jruoho 12749 1.1 jruoho 12750 1.1 jruoho ---------------------------------------- 12751 1.1 jruoho Summary of changes for this release: 03_08_02 12752 1.1 jruoho 12753 1.1 jruoho 12754 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020308: 12755 1.1 jruoho 12756 1.1 jruoho Fixed a problem with AML Fields where the use of the "AccessAny" 12757 1.1 jruoho keyword could cause an interpreter error due to attempting to read 12758 1.1 jruoho or write beyond the end of the parent Operation Region. 12759 1.1 jruoho 12760 1.1 jruoho Fixed a problem in the SystemMemory Operation Region handler where 12761 1.1 jruoho an attempt was made to map memory beyond the end of the region. 12762 1.1 jruoho This was the root cause of the "AE_ERROR" and "AE_NO_MEMORY" 12763 1.1 jruoho errors on some Linux systems. 12764 1.1 jruoho 12765 1.1 jruoho Fixed a problem where the interpreter/namespace "search to root" 12766 1.1 jruoho algorithm was not functioning for some object types. Relaxed the 12767 1.1 jruoho internal restriction on the search to allow upsearches for all 12768 1.1 jruoho external object types as well as most internal types. 12769 1.1 jruoho 12770 1.1 jruoho 12771 1.1 jruoho 2) Linux: 12772 1.1 jruoho 12773 1.1 jruoho We now use safe_halt() macro versus individual calls to sti | hlt. 12774 1.1 jruoho 12775 1.1 jruoho Writing to the processor limit interface should now work. "echo 1" 12776 1.1 jruoho will increase the limit, 2 will decrease, and 0 will reset to the 12777 1.1 jruoho 12778 1.1 jruoho default. 12779 1.1 jruoho 12780 1.1 jruoho 12781 1.1 jruoho 3) ASL compiler: 12782 1.1 jruoho 12783 1.1 jruoho Fixed segfault on Linux version. 12784 1.1 jruoho 12785 1.1 jruoho 12786 1.1 jruoho ---------------------------------------- 12787 1.1 jruoho Summary of changes for this release: 02_25_02 12788 1.1 jruoho 12789 1.1 jruoho 1) ACPI CA Core Subsystem: 12790 1.1 jruoho 12791 1.1 jruoho 12792 1.1 jruoho Fixed a problem where the GPE bit masks were not initialized 12793 1.1 jruoho properly, causing erratic GPE behavior. 12794 1.1 jruoho 12795 1.1 jruoho Implemented limited support for multiple calling conventions. The 12796 1.1 jruoho code can be generated with either the VPL (variable parameter 12797 1.1 jruoho list, or "C") convention, or the FPL (fixed parameter list, or 12798 1.1 jruoho "Pascal") convention. The core subsystem is about 3.4% smaller 12799 1.1 jruoho when generated with FPL. 12800 1.1 jruoho 12801 1.1 jruoho 12802 1.1 jruoho 2) Linux 12803 1.1 jruoho 12804 1.1 jruoho Re-add some /proc/acpi/event functionality that was lost during 12805 1.1 jruoho the rewrite 12806 1.1 jruoho 12807 1.1 jruoho Resolved issue with /proc events for fixed-feature buttons showing 12808 1.1 jruoho up as the system device. 12809 1.1 jruoho 12810 1.1 jruoho Fixed checks on C2/C3 latencies to be inclusive of maximum values. 12811 1.1 jruoho 12812 1.1 jruoho Replaced AE_ERRORs in acpi_osl.c with more specific error codes. 12813 1.1 jruoho 12814 1.1 jruoho Changed ACPI PRT option from "pci=noacpi-routing" to "pci=noacpi" 12815 1.1 jruoho 12816 1.1 jruoho Fixed limit interface & usage to fix bugs with passive cooling 12817 1.1 jruoho hysterisis. 12818 1.1 jruoho 12819 1.1 jruoho Restructured PRT support. 12820 1.1 jruoho 12821 1.1 jruoho 12822 1.1 jruoho ---------------------------------------- 12823 1.1 jruoho Summary of changes for this label: 02_14_02 12824 1.1 jruoho 12825 1.1 jruoho 12826 1.1 jruoho 1) ACPI CA Core Subsystem: 12827 1.1 jruoho 12828 1.1 jruoho Implemented support in AcpiLoadTable to allow loading of FACS and 12829 1.1 jruoho FADT tables. 12830 1.1 jruoho 12831 1.1 jruoho Suport for the now-obsolete interim 0.71 64-bit ACPI tables has 12832 1.1 jruoho been removed. All 64-bit platforms should be migrated to the ACPI 12833 1.1 jruoho 2.0 tables. The actbl71.h header has been removed from the source 12834 1.1 jruoho tree. 12835 1.1 jruoho 12836 1.1 jruoho All C macros defined within the subsystem have been prefixed with 12837 1.1 jruoho "ACPI_" to avoid collision with other system include files. 12838 1.1 jruoho 12839 1.1 jruoho Removed the return value for the two AcpiOsPrint interfaces, since 12840 1.1 jruoho it is never used and causes lint warnings for ignoring the return 12841 1.1 jruoho value. 12842 1.1 jruoho 12843 1.1 jruoho Added error checking to all internal mutex acquire and release 12844 1.1 jruoho calls. Although a failure from one of these interfaces is 12845 1.1 jruoho probably a fatal system error, these checks will cause the 12846 1.1 jruoho immediate abort of the currently executing method or interface. 12847 1.1 jruoho 12848 1.1 jruoho Fixed a problem where the AcpiSetCurrentResources interface could 12849 1.1 jruoho fault. This was a side effect of the deployment of the new memory 12850 1.1 jruoho allocation model. 12851 1.1 jruoho 12852 1.1 jruoho Fixed a couple of problems with the Global Lock support introduced 12853 1.1 jruoho in the last major build. The "common" (1.0/2.0) internal FACS was 12854 1.1 jruoho being overwritten with the FACS signature and clobbering the 12855 1.1 jruoho Global Lock pointer. Also, the actual firmware FACS was being 12856 1.1 jruoho unmapped after construction of the "common" FACS, preventing 12857 1.1 jruoho access to the actual Global Lock field within it. The "common" 12858 1.1 jruoho internal FACS is no longer installed as an actual ACPI table; it 12859 1.1 jruoho is used simply as a global. 12860 1.1 jruoho 12861 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12862 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12863 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12864 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12865 1.1 jruoho version of the code includes the debug output trace mechanism and 12866 1.1 jruoho has a larger code and data size. Note that these values will vary 12867 1.1 jruoho depending on the efficiency of the compiler and the compiler 12868 1.1 jruoho options used during generation. 12869 1.1 jruoho 12870 1.1 jruoho Previous Release (02_07_01) 12871 1.1 jruoho Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total 12872 1.1 jruoho Debug Version: 136.9K Code, 56.4K Data, 193.3K Total 12873 1.1 jruoho Current Release: 12874 1.1 jruoho Non-Debug Version: 65.4K Code, 6.2K Data, 71.6K Total 12875 1.1 jruoho Debug Version: 138.0K Code, 56.6K Data, 194.6K Total 12876 1.1 jruoho 12877 1.1 jruoho 12878 1.1 jruoho 2) Linux 12879 1.1 jruoho 12880 1.1 jruoho Updated Linux-specific code for core macro and OSL interface 12881 1.1 jruoho changes described above. 12882 1.1 jruoho 12883 1.1 jruoho Improved /proc/acpi/event. It now can be opened only once and has 12884 1.1 jruoho proper poll functionality. 12885 1.1 jruoho 12886 1.1 jruoho Fixed and restructured power management (acpi_bus). 12887 1.1 jruoho 12888 1.1 jruoho Only create /proc "view by type" when devices of that class exist. 12889 1.1 jruoho 12890 1.1 jruoho Fixed "charging/discharging" bug (and others) in acpi_battery. 12891 1.1 jruoho 12892 1.1 jruoho Improved thermal zone code. 12893 1.1 jruoho 12894 1.1 jruoho 12895 1.1 jruoho 3) ASL Compiler, version X2039: 12896 1.1 jruoho 12897 1.1 jruoho 12898 1.1 jruoho Implemented the new compiler restriction on ASL String hex/octal 12899 1.1 jruoho escapes to non-null, ASCII values. An error results if an invalid 12900 1.1 jruoho value is used. (This will require an ACPI 2.0 specification 12901 1.1 jruoho change.) 12902 1.1 jruoho 12903 1.1 jruoho AML object labels that are output to the optional C and ASM source 12904 1.1 jruoho are now prefixed with both the ACPI table signature and table ID 12905 1.1 jruoho to help guarantee uniqueness within a large BIOS project. 12906 1.1 jruoho 12907 1.1 jruoho 12908 1.1 jruoho ---------------------------------------- 12909 1.1 jruoho Summary of changes for this label: 02_01_02 12910 1.1 jruoho 12911 1.1 jruoho 1) ACPI CA Core Subsystem: 12912 1.1 jruoho 12913 1.1 jruoho ACPI 2.0 support is complete in the entire Core Subsystem and the 12914 1.1 jruoho ASL compiler. All new ACPI 2.0 operators are implemented and all 12915 1.1 jruoho other changes for ACPI 2.0 support are complete. With 12916 1.1 jruoho simultaneous code and data optimizations throughout the subsystem, 12917 1.1 jruoho ACPI 2.0 support has been implemented with almost no additional 12918 1.1 jruoho cost in terms of code and data size. 12919 1.1 jruoho 12920 1.1 jruoho Implemented a new mechanism for allocation of return buffers. If 12921 1.1 jruoho the buffer length is set to ACPI_ALLOCATE_BUFFER, the buffer will 12922 1.1 jruoho be allocated on behalf of the caller. Consolidated all return 12923 1.1 jruoho buffer validation and allocation to a common procedure. Return 12924 1.1 jruoho buffers will be allocated via the primary OSL allocation interface 12925 1.1 jruoho since it appears that a separate pool is not needed by most users. 12926 1.1 jruoho If a separate pool is required for these buffers, the caller can 12927 1.1 jruoho still use the original mechanism and pre-allocate the buffer(s). 12928 1.1 jruoho 12929 1.1 jruoho Implemented support for string operands within the DerefOf 12930 1.1 jruoho operator. 12931 1.1 jruoho 12932 1.1 jruoho Restructured the Hardware and Event managers to be table driven, 12933 1.1 jruoho simplifying the source code and reducing the amount of generated 12934 1.1 jruoho code. 12935 1.1 jruoho 12936 1.1 jruoho Split the common read/write low-level ACPI register bitfield 12937 1.1 jruoho procedure into a separate read and write, simplifying the code 12938 1.1 jruoho considerably. 12939 1.1 jruoho 12940 1.1 jruoho Obsoleted the AcpiOsCallocate OSL interface. This interface was 12941 1.1 jruoho used only a handful of times and didn't have enough critical mass 12942 1.1 jruoho for a separate interface. Replaced with a common calloc procedure 12943 1.1 jruoho in the core. 12944 1.1 jruoho 12945 1.1 jruoho Fixed a reported problem with the GPE number mapping mechanism 12946 1.1 jruoho that allows GPE1 numbers to be non-contiguous with GPE0. 12947 1.1 jruoho Reorganized the GPE information and shrunk a large array that was 12948 1.1 jruoho originally large enough to hold info for all possible GPEs (256) 12949 1.1 jruoho to simply large enough to hold all GPEs up to the largest GPE 12950 1.1 jruoho number on the machine. 12951 1.1 jruoho 12952 1.1 jruoho Fixed a reported problem with resource structure alignment on 64- 12953 1.1 jruoho bit platforms. 12954 1.1 jruoho 12955 1.1 jruoho Changed the AcpiEnableEvent and AcpiDisableEvent external 12956 1.1 jruoho interfaces to not require any flags for the common case of 12957 1.1 jruoho enabling/disabling a GPE. 12958 1.1 jruoho 12959 1.1 jruoho Implemented support to allow a "Notify" on a Processor object. 12960 1.1 jruoho 12961 1.1 jruoho Most TBDs in comments within the source code have been resolved 12962 1.1 jruoho and eliminated. 12963 1.1 jruoho 12964 1.1 jruoho 12965 1.1 jruoho Fixed a problem in the interpreter where a standalone parent 12966 1.1 jruoho prefix (^) was not handled correctly in the interpreter and 12967 1.1 jruoho debugger. 12968 1.1 jruoho 12969 1.1 jruoho Removed obsolete and unnecessary GPE save/restore code. 12970 1.1 jruoho 12971 1.1 jruoho Implemented Field support in the ASL Load operator. This allows a 12972 1.1 jruoho table to be loaded from a named field, in addition to loading a 12973 1.1 jruoho table directly from an Operation Region. 12974 1.1 jruoho 12975 1.1 jruoho Implemented timeout and handle support in the external Global Lock 12976 1.1 jruoho interfaces. 12977 1.1 jruoho 12978 1.1 jruoho Fixed a problem in the AcpiDump utility where pathnames were no 12979 1.1 jruoho longer being generated correctly during the dump of named objects. 12980 1.1 jruoho 12981 1.1 jruoho Modified the AML debugger to give a full display of if/while 12982 1.1 jruoho predicates instead of just one AML opcode at a time. (The 12983 1.1 jruoho predicate can have several nested ASL statements.) The old method 12984 1.1 jruoho was confusing during single stepping. 12985 1.1 jruoho 12986 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 12987 1.1 jruoho below. These are the code and data sizes for the acpica.lib 12988 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 12989 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 12990 1.1 jruoho version of the code includes the debug output trace mechanism and 12991 1.1 jruoho has a larger code and data size. Note that these values will vary 12992 1.1 jruoho depending on the efficiency of the compiler and the compiler 12993 1.1 jruoho options used during generation. 12994 1.1 jruoho 12995 1.1 jruoho Previous Release (12_18_01) 12996 1.1 jruoho Non-Debug Version: 66.1K Code, 5.5K Data, 71.6K Total 12997 1.1 jruoho Debug Version: 138.3K Code, 55.9K Data, 194.2K Total 12998 1.1 jruoho Current Release: 12999 1.1 jruoho Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total 13000 1.1 jruoho Debug Version: 136.9K Code, 56.4K Data, 193.3K Total 13001 1.1 jruoho 13002 1.1 jruoho 2) Linux 13003 1.1 jruoho 13004 1.1 jruoho Implemented fix for PIIX reverse throttling errata (Processor 13005 1.1 jruoho driver) 13006 1.1 jruoho 13007 1.1 jruoho Added new Limit interface (Processor and Thermal drivers) 13008 1.1 jruoho 13009 1.1 jruoho New thermal policy (Thermal driver) 13010 1.1 jruoho 13011 1.1 jruoho Many updates to /proc 13012 1.1 jruoho 13013 1.1 jruoho Battery "low" event support (Battery driver) 13014 1.1 jruoho 13015 1.1 jruoho Supports ACPI PCI IRQ routing (PCI Link and PCI root drivers) 13016 1.1 jruoho 13017 1.1 jruoho IA32 - IA64 initialization unification, no longer experimental 13018 1.1 jruoho 13019 1.1 jruoho Menuconfig options redesigned 13020 1.1 jruoho 13021 1.1 jruoho 3) ASL Compiler, version X2037: 13022 1.1 jruoho 13023 1.1 jruoho Implemented several new output features to simplify integration of 13024 1.1 jruoho AML code into firmware: 1) Output the AML in C source code with 13025 1.1 jruoho labels for each named ASL object. The original ASL source code 13026 1.1 jruoho is interleaved as C comments. 2) Output the AML in ASM source code 13027 1.1 jruoho with labels and interleaved ASL source. 3) Output the AML in 13028 1.1 jruoho raw hex table form, in either C or ASM. 13029 1.1 jruoho 13030 1.1 jruoho Implemented support for optional string parameters to the 13031 1.1 jruoho LoadTable operator. 13032 1.1 jruoho 13033 1.1 jruoho Completed support for embedded escape sequences within string 13034 1.1 jruoho literals. The compiler now supports all single character escapes 13035 1.1 jruoho as well as the Octal and Hex escapes. Note: the insertion of a 13036 1.1 jruoho null byte into a string literal (via the hex/octal escape) causes 13037 1.1 jruoho the string to be immediately terminated. A warning is issued. 13038 1.1 jruoho 13039 1.1 jruoho Fixed a problem where incorrect AML was generated for the case 13040 1.1 jruoho where an ASL namepath consists of a single parent prefix ( 13041 1.1 jruoho 13042 1.1 jruoho ) with no trailing name segments. 13043 1.1 jruoho 13044 1.1 jruoho The compiler has been successfully generated with a 64-bit C 13045 1.1 jruoho compiler. 13046 1.1 jruoho 13047 1.1 jruoho 13048 1.1 jruoho 13049 1.1 jruoho 13050 1.1 jruoho ---------------------------------------- 13051 1.1 jruoho Summary of changes for this label: 12_18_01 13052 1.1 jruoho 13053 1.1 jruoho 1) Linux 13054 1.1 jruoho 13055 1.1 jruoho Enhanced blacklist with reason and severity fields. Any table's 13056 1.1 jruoho signature may now be used to identify a blacklisted system. 13057 1.1 jruoho 13058 1.1 jruoho Call _PIC control method to inform the firmware which interrupt 13059 1.1 jruoho model the OS is using. Turn on any disabled link devices. 13060 1.1 jruoho 13061 1.1 jruoho Cleaned up busmgr /proc error handling (Andreas Dilger) 13062 1.1 jruoho 13063 1.1 jruoho 2) ACPI CA Core Subsystem: 13064 1.1 jruoho 13065 1.1 jruoho Implemented ACPI 2.0 semantics for the "Break" operator (Exit from 13066 1.1 jruoho while loop) 13067 1.1 jruoho 13068 1.1 jruoho Completed implementation of the ACPI 2.0 "Continue", 13069 1.1 jruoho "ConcatenateResTemplate", "DataTableRegion", and "LoadTable" 13070 1.1 jruoho operators. All new ACPI 2.0 operators are now implemented in both 13071 1.1 jruoho the ASL compiler and the AML interpreter. The only remaining ACPI 13072 1.1 jruoho 2.0 task is support for the String data type in the DerefOf 13073 1.1 jruoho operator. Fixed a problem with AcquireMutex where the status code 13074 1.1 jruoho was lost if the caller had to actually wait for the mutex. 13075 1.1 jruoho 13076 1.1 jruoho Increased the maximum ASL Field size from 64K bits to 4G bits. 13077 1.1 jruoho 13078 1.1 jruoho Completed implementation of the external Global Lock interfaces -- 13079 1.1 jruoho AcpiAcquireGlobalLock and AcpiReleaseGlobalLock. The Timeout and 13080 1.1 jruoho Handler parameters were added. 13081 1.1 jruoho 13082 1.1 jruoho Completed another pass at removing warnings and issues when 13083 1.1 jruoho compiling with 64-bit compilers. The code now compiles cleanly 13084 1.1 jruoho with the Intel 64-bit C/C++ compiler. Most notably, the pointer 13085 1.1 jruoho add and subtract (diff) macros have changed considerably. 13086 1.1 jruoho 13087 1.1 jruoho 13088 1.1 jruoho Created and deployed a new ACPI_SIZE type that is 64-bits wide on 13089 1.1 jruoho 64-bit platforms, 32-bits on all others. This type is used 13090 1.1 jruoho wherever memory allocation and/or the C sizeof() operator is used, 13091 1.1 jruoho and affects the OSL memory allocation interfaces AcpiOsAllocate 13092 1.1 jruoho and AcpiOsCallocate. 13093 1.1 jruoho 13094 1.1 jruoho Implemented sticky user breakpoints in the AML debugger. 13095 1.1 jruoho 13096 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 13097 1.1 jruoho below. These are the code and data sizes for the acpica.lib 13098 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 13099 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 13100 1.1 jruoho version of the code includes the debug output trace mechanism and 13101 1.1 jruoho has a larger code and data size. Note that these values will vary 13102 1.1 jruoho depending on the efficiency of the compiler and the compiler 13103 1.1 jruoho options used during generation. 13104 1.1 jruoho 13105 1.1 jruoho Previous Release (12_05_01) 13106 1.1 jruoho Non-Debug Version: 64.7K Code, 5.3K Data, 70.0K Total 13107 1.1 jruoho Debug Version: 136.2K Code, 55.6K Data, 191.8K Total 13108 1.1 jruoho Current Release: 13109 1.1 jruoho Non-Debug Version: 66.1K Code, 5.5K Data, 71.6K Total 13110 1.1 jruoho Debug Version: 138.3K Code, 55.9K Data, 194.2K Total 13111 1.1 jruoho 13112 1.1 jruoho 3) ASL Compiler, version X2034: 13113 1.1 jruoho 13114 1.1 jruoho Now checks for (and generates an error if detected) the use of a 13115 1.1 jruoho Break or Continue statement without an enclosing While statement. 13116 1.1 jruoho 13117 1.1 jruoho 13118 1.1 jruoho Successfully generated the compiler with the Intel 64-bit C 13119 1.1 jruoho compiler. 13120 1.1 jruoho 13121 1.1 jruoho ---------------------------------------- 13122 1.1 jruoho Summary of changes for this label: 12_05_01 13123 1.1 jruoho 13124 1.1 jruoho 1) ACPI CA Core Subsystem: 13125 1.1 jruoho 13126 1.1 jruoho The ACPI 2.0 CopyObject operator is fully implemented. This 13127 1.1 jruoho operator creates a new copy of an object (and is also used to 13128 1.1 jruoho bypass the "implicit conversion" mechanism of the Store operator.) 13129 1.1 jruoho 13130 1.1 jruoho The ACPI 2.0 semantics for the SizeOf operator are fully 13131 1.1 jruoho implemented. The change is that performing a SizeOf on a 13132 1.1 jruoho reference object causes an automatic dereference of the object to 13133 1.1 jruoho tha actual value before the size is evaluated. This behavior was 13134 1.1 jruoho undefined in ACPI 1.0. 13135 1.1 jruoho 13136 1.1 jruoho The ACPI 2.0 semantics for the Extended IRQ resource descriptor 13137 1.1 jruoho have been implemented. The interrupt polarity and mode are now 13138 1.1 jruoho independently set. 13139 1.1 jruoho 13140 1.1 jruoho Fixed a problem where ASL Constants (Zero, One, Ones, Revision) 13141 1.1 jruoho appearing in Package objects were not properly converted to 13142 1.1 jruoho integers when the internal Package was converted to an external 13143 1.1 jruoho object (via the AcpiEvaluateObject interface.) 13144 1.1 jruoho 13145 1.1 jruoho Fixed a problem with the namespace object deletion mechanism for 13146 1.1 jruoho objects created by control methods. There were two parts to this 13147 1.1 jruoho problem: 1) Objects created during the initialization phase method 13148 1.1 jruoho parse were not being deleted, and 2) The object owner ID mechanism 13149 1.1 jruoho to track objects was broken. 13150 1.1 jruoho 13151 1.1 jruoho Fixed a problem where the use of the ASL Scope operator within a 13152 1.1 jruoho control method would result in an invalid opcode exception. 13153 1.1 jruoho 13154 1.1 jruoho Fixed a problem introduced in the previous label where the buffer 13155 1.1 jruoho length required for the _PRT structure was not being returned 13156 1.1 jruoho correctly. 13157 1.1 jruoho 13158 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 13159 1.1 jruoho below. These are the code and data sizes for the acpica.lib 13160 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 13161 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 13162 1.1 jruoho version of the code includes the debug output trace mechanism and 13163 1.1 jruoho has a larger code and data size. Note that these values will vary 13164 1.1 jruoho depending on the efficiency of the compiler and the compiler 13165 1.1 jruoho options used during generation. 13166 1.1 jruoho 13167 1.1 jruoho Previous Release (11_20_01) 13168 1.1 jruoho Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total 13169 1.1 jruoho Debug Version: 135.1K Code, 55.4K Data, 190.5K Total 13170 1.1 jruoho 13171 1.1 jruoho Current Release: 13172 1.1 jruoho Non-Debug Version: 64.7K Code, 5.3K Data, 70.0K Total 13173 1.1 jruoho Debug Version: 136.2K Code, 55.6K Data, 191.8K Total 13174 1.1 jruoho 13175 1.1 jruoho 2) Linux: 13176 1.1 jruoho 13177 1.1 jruoho Updated all files to apply cleanly against 2.4.16. 13178 1.1 jruoho 13179 1.1 jruoho Added basic PCI Interrupt Routing Table (PRT) support for IA32 13180 1.1 jruoho (acpi_pci.c), and unified the PRT code for IA32 and IA64. This 13181 1.1 jruoho version supports both static and dyanmic PRT entries, but dynamic 13182 1.1 jruoho entries are treated as if they were static (not yet 13183 1.1 jruoho reconfigurable). Architecture- specific code to use this data is 13184 1.1 jruoho absent on IA32 but should be available shortly. 13185 1.1 jruoho 13186 1.1 jruoho Changed the initialization sequence to start the ACPI interpreter 13187 1.1 jruoho (acpi_init) prior to initialization of the PCI driver (pci_init) 13188 1.1 jruoho in init/main.c. This ordering is required to support PRT and 13189 1.1 jruoho facilitate other (future) enhancement. A side effect is that the 13190 1.1 jruoho ACPI bus driver and certain device drivers can no longer be loaded 13191 1.1 jruoho as modules. 13192 1.1 jruoho 13193 1.1 jruoho Modified the 'make menuconfig' options to allow PCI Interrupt 13194 1.1 jruoho Routing support to be included without the ACPI Bus and other 13195 1.1 jruoho device drivers. 13196 1.1 jruoho 13197 1.1 jruoho 3) ASL Compiler, version X2033: 13198 1.1 jruoho 13199 1.1 jruoho Fixed some issues with the use of the new CopyObject and 13200 1.1 jruoho DataTableRegion operators. Both are fully functional. 13201 1.1 jruoho 13202 1.1 jruoho ---------------------------------------- 13203 1.1 jruoho Summary of changes for this label: 11_20_01 13204 1.1 jruoho 13205 1.1 jruoho 20 November 2001. Summary of changes for this release. 13206 1.1 jruoho 13207 1.1 jruoho 1) ACPI CA Core Subsystem: 13208 1.1 jruoho 13209 1.1 jruoho Updated Index support to match ACPI 2.0 semantics. Storing a 13210 1.1 jruoho Integer, String, or Buffer to an Index of a Buffer will store only 13211 1.1 jruoho the least-significant byte of the source to the Indexed buffer 13212 1.1 jruoho byte. Multiple writes are not performed. 13213 1.1 jruoho 13214 1.1 jruoho Fixed a problem where the access type used in an AccessAs ASL 13215 1.1 jruoho operator was not recorded correctly into the field object. 13216 1.1 jruoho 13217 1.1 jruoho Fixed a problem where ASL Event objects were created in a 13218 1.1 jruoho signalled state. Events are now created in an unsignalled state. 13219 1.1 jruoho 13220 1.1 jruoho The internal object cache is now purged after table loading and 13221 1.1 jruoho initialization to reduce the use of dynamic kernel memory -- on 13222 1.1 jruoho the assumption that object use is greatest during the parse phase 13223 1.1 jruoho of the entire table (versus the run-time use of individual control 13224 1.1 jruoho methods.) 13225 1.1 jruoho 13226 1.1 jruoho ACPI 2.0 variable-length packages are now fully operational. 13227 1.1 jruoho 13228 1.1 jruoho Code and Data Size: Code and Data optimizations have permitted new 13229 1.1 jruoho feature development with an actual reduction in the library size. 13230 1.1 jruoho Current core subsystem library sizes are shown below. These are 13231 1.1 jruoho the code and data sizes for the acpica.lib produced by the 13232 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 13233 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 13234 1.1 jruoho includes the debug output trace mechanism and has a larger code 13235 1.1 jruoho and data size. Note that these values will vary depending on the 13236 1.1 jruoho efficiency of the compiler and the compiler options used during 13237 1.1 jruoho generation. 13238 1.1 jruoho 13239 1.1 jruoho Previous Release (11_09_01): 13240 1.1 jruoho Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 13241 1.1 jruoho Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 13242 1.1 jruoho 13243 1.1 jruoho Current Release: 13244 1.1 jruoho Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total 13245 1.1 jruoho Debug Version: 135.1K Code, 55.4K Data, 190.5K Total 13246 1.1 jruoho 13247 1.1 jruoho 2) Linux: 13248 1.1 jruoho 13249 1.1 jruoho Enhanced the ACPI boot-time initialization code to allow the use 13250 1.1 jruoho of Local APIC tables for processor enumeration on IA-32, and to 13251 1.1 jruoho pave the way for a fully MPS-free boot (on SMP systems) in the 13252 1.1 jruoho near future. This functionality replaces 13253 1.1 jruoho arch/i386/kernel/acpitables.c, which was introduced in an earlier 13254 1.1 jruoho 2.4.15-preX release. To enable this feature you must add 13255 1.1 jruoho "acpi_boot=on" to the kernel command line -- see the help entry 13256 1.1 jruoho for CONFIG_ACPI_BOOT for more information. An IA-64 release is in 13257 1.1 jruoho the works... 13258 1.1 jruoho 13259 1.1 jruoho Restructured the configuration options to allow boot-time table 13260 1.1 jruoho parsing support without inclusion of the ACPI Interpreter (and 13261 1.1 jruoho other) code. 13262 1.1 jruoho 13263 1.1 jruoho NOTE: This release does not include fixes for the reported events, 13264 1.1 jruoho power-down, and thermal passive cooling issues (coming soon). 13265 1.1 jruoho 13266 1.1 jruoho 3) ASL Compiler: 13267 1.1 jruoho 13268 1.1 jruoho Added additional typechecking for Fields within restricted access 13269 1.1 jruoho Operation Regions. All fields within EC and CMOS regions must be 13270 1.1 jruoho declared with ByteAcc. All fields withing SMBus regions must be 13271 1.1 jruoho declared with the BufferAcc access type. 13272 1.1 jruoho 13273 1.1 jruoho Fixed a problem where the listing file output of control methods 13274 1.1 jruoho no longer interleaved the actual AML code with the ASL source 13275 1.1 jruoho code. 13276 1.1 jruoho 13277 1.1 jruoho 13278 1.1 jruoho 13279 1.1 jruoho 13280 1.1 jruoho ---------------------------------------- 13281 1.1 jruoho Summary of changes for this label: 11_09_01 13282 1.1 jruoho 13283 1.1 jruoho 1) ACPI CA Core Subsystem: 13284 1.1 jruoho 13285 1.1 jruoho Implemented ACPI 2.0-defined support for writes to fields with a 13286 1.1 jruoho Buffer, String, or Integer source operand that is smaller than the 13287 1.1 jruoho target field. In these cases, the source operand is zero-extended 13288 1.1 jruoho to fill the target field. 13289 1.1 jruoho 13290 1.1 jruoho Fixed a problem where a Field starting bit offset (within the 13291 1.1 jruoho parent operation region) was calculated incorrectly if the 13292 1.1 jruoho 13293 1.1 jruoho alignment of the field differed from the access width. This 13294 1.1 jruoho affected CreateWordField, CreateDwordField, CreateQwordField, and 13295 1.1 jruoho possibly other fields that use the "AccessAny" keyword. 13296 1.1 jruoho 13297 1.1 jruoho Fixed a problem introduced in the 11_02_01 release where indirect 13298 1.1 jruoho stores through method arguments did not operate correctly. 13299 1.1 jruoho 13300 1.1 jruoho 2) Linux: 13301 1.1 jruoho 13302 1.1 jruoho Implemented boot-time ACPI table parsing support 13303 1.1 jruoho (CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code 13304 1.1 jruoho facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than 13305 1.1 jruoho legacy BIOS interfaces (e.g. MPS) for the configuration of system 13306 1.1 jruoho processors, memory, and interrupts during setup_arch(). Note that 13307 1.1 jruoho this patch does not include the required architecture-specific 13308 1.1 jruoho changes required to apply this information -- subsequent patches 13309 1.1 jruoho will be posted for both IA32 and IA64 to achieve this. 13310 1.1 jruoho 13311 1.1 jruoho Added low-level sleep support for IA32 platforms, courtesy of Pat 13312 1.1 jruoho Mochel. This allows IA32 systems to transition to/from various 13313 1.1 jruoho sleeping states (e.g. S1, S3), although the lack of a centralized 13314 1.1 jruoho driver model and power-manageable drivers will prevent its 13315 1.1 jruoho (successful) use on most systems. 13316 1.1 jruoho 13317 1.1 jruoho Revamped the ACPI 'menuconfig' layout: created new "ACPI Support" 13318 1.1 jruoho submenu, unified IA32 and IA64 options, added new "Boot using ACPI 13319 1.1 jruoho tables" option, etc. 13320 1.1 jruoho 13321 1.1 jruoho Increased the default timeout for the EC driver from 1ms to 10ms 13322 1.1 jruoho (1000 cycles of 10us) to try to address AE_TIME errors during EC 13323 1.1 jruoho transactions. 13324 1.1 jruoho 13325 1.1 jruoho ---------------------------------------- 13326 1.1 jruoho Summary of changes for this label: 11_02_01 13327 1.1 jruoho 13328 1.1 jruoho 1) ACPI CA Core Subsystem: 13329 1.1 jruoho 13330 1.1 jruoho ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access 13331 1.1 jruoho (QWordAcc keyword). All ACPI 2.0 64-bit support is now 13332 1.1 jruoho implemented. 13333 1.1 jruoho 13334 1.1 jruoho OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required 13335 1.1 jruoho changes to support ACPI 2.0 Qword field access. Read/Write 13336 1.1 jruoho PciConfiguration(), Read/Write Memory(), and Read/Write Port() now 13337 1.1 jruoho accept an ACPI_INTEGER (64 bits) as the value parameter. Also, 13338 1.1 jruoho the value parameter for the address space handler interface is now 13339 1.1 jruoho an ACPI_INTEGER. OSL implementations of these interfaces must now 13340 1.1 jruoho handle the case where the Width parameter is 64. 13341 1.1 jruoho 13342 1.1 jruoho Index Fields: Fixed a problem where unaligned bit assembly and 13343 1.1 jruoho disassembly for IndexFields was not supported correctly. 13344 1.1 jruoho 13345 1.1 jruoho Index and Bank Fields: Nested Index and Bank Fields are now 13346 1.1 jruoho supported. During field access, a check is performed to ensure 13347 1.1 jruoho that the value written to an Index or Bank register is not out of 13348 1.1 jruoho the range of the register. The Index (or Bank) register is 13349 1.1 jruoho written before each access to the field data. Future support will 13350 1.1 jruoho include allowing individual IndexFields to be wider than the 13351 1.1 jruoho DataRegister width. 13352 1.1 jruoho 13353 1.1 jruoho Fields: Fixed a problem where the AML interpreter was incorrectly 13354 1.1 jruoho attempting to write beyond the end of a Field/OpRegion. This was 13355 1.1 jruoho a boundary case that occurred when a DWORD field was written to a 13356 1.1 jruoho BYTE access OpRegion, forcing multiple writes and causing the 13357 1.1 jruoho interpreter to write one datum too many. 13358 1.1 jruoho 13359 1.1 jruoho Fields: Fixed a problem with Field/OpRegion access where the 13360 1.1 jruoho starting bit address of a field was incorrectly calculated if the 13361 1.1 jruoho current access type was wider than a byte (WordAcc, DwordAcc, or 13362 1.1 jruoho QwordAcc). 13363 1.1 jruoho 13364 1.1 jruoho Fields: Fixed a problem where forward references to individual 13365 1.1 jruoho FieldUnits (individual Field names within a Field definition) were 13366 1.1 jruoho not resolved during the AML table load. 13367 1.1 jruoho 13368 1.1 jruoho Fields: Fixed a problem where forward references from a Field 13369 1.1 jruoho definition to the parent Operation Region definition were not 13370 1.1 jruoho resolved during the AML table load. 13371 1.1 jruoho 13372 1.1 jruoho Fields: Duplicate FieldUnit names within a scope are now detected 13373 1.1 jruoho during AML table load. 13374 1.1 jruoho 13375 1.1 jruoho Acpi Interfaces: Fixed a problem where the AcpiGetName() interface 13376 1.1 jruoho returned an incorrect name for the root node. 13377 1.1 jruoho 13378 1.1 jruoho Code and Data Size: Code and Data optimizations have permitted new 13379 1.1 jruoho feature development with an actual reduction in the library size. 13380 1.1 jruoho Current core subsystem library sizes are shown below. These are 13381 1.1 jruoho the code and data sizes for the acpica.lib produced by the 13382 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 13383 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 13384 1.1 jruoho includes the debug output trace mechanism and has a larger code 13385 1.1 jruoho and data size. Note that these values will vary depending on the 13386 1.1 jruoho efficiency of the compiler and the compiler options used during 13387 1.1 jruoho generation. 13388 1.1 jruoho 13389 1.1 jruoho Previous Release (10_18_01): 13390 1.1 jruoho Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total 13391 1.1 jruoho Debug Version: 136.7K Code, 57.4K Data, 194.2K Total 13392 1.1 jruoho 13393 1.1 jruoho Current Release: 13394 1.1 jruoho Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 13395 1.1 jruoho Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 13396 1.1 jruoho 13397 1.1 jruoho 2) Linux: 13398 1.1 jruoho 13399 1.1 jruoho Improved /proc processor output (Pavel Machek) Re-added 13400 1.1 jruoho MODULE_LICENSE("GPL") to all modules. 13401 1.1 jruoho 13402 1.1 jruoho 3) ASL Compiler version X2030: 13403 1.1 jruoho 13404 1.1 jruoho Duplicate FieldUnit names within a scope are now detected and 13405 1.1 jruoho flagged as errors. 13406 1.1 jruoho 13407 1.1 jruoho 4) Documentation: 13408 1.1 jruoho 13409 1.1 jruoho Programmer Reference updated to reflect OSL and address space 13410 1.1 jruoho handler interface changes described above. 13411 1.1 jruoho 13412 1.1 jruoho ---------------------------------------- 13413 1.1 jruoho Summary of changes for this label: 10_18_01 13414 1.1 jruoho 13415 1.1 jruoho ACPI CA Core Subsystem: 13416 1.1 jruoho 13417 1.1 jruoho Fixed a problem with the internal object reference count mechanism 13418 1.1 jruoho that occasionally caused premature object deletion. This resolves 13419 1.1 jruoho all of the outstanding problem reports where an object is deleted 13420 1.1 jruoho in the middle of an interpreter evaluation. Although this problem 13421 1.1 jruoho only showed up in rather obscure cases, the solution to the 13422 1.1 jruoho problem involved an adjustment of all reference counts involving 13423 1.1 jruoho objects attached to namespace nodes. 13424 1.1 jruoho 13425 1.1 jruoho Fixed a problem with Field support in the interpreter where 13426 1.1 jruoho writing to an aligned field whose length is an exact multiple (2 13427 1.1 jruoho or greater) of the field access granularity would cause an attempt 13428 1.1 jruoho to write beyond the end of the field. 13429 1.1 jruoho 13430 1.1 jruoho The top level AML opcode execution functions within the 13431 1.1 jruoho interpreter have been renamed with a more meaningful and 13432 1.1 jruoho consistent naming convention. The modules exmonad.c and 13433 1.1 jruoho exdyadic.c were eliminated. New modules are exoparg1.c, 13434 1.1 jruoho exoparg2.c, exoparg3.c, and exoparg6.c. 13435 1.1 jruoho 13436 1.1 jruoho Support for the ACPI 2.0 "Mid" ASL operator has been implemented. 13437 1.1 jruoho 13438 1.1 jruoho Fixed a problem where the AML debugger was causing some internal 13439 1.1 jruoho objects to not be deleted during subsystem termination. 13440 1.1 jruoho 13441 1.1 jruoho Fixed a problem with the external AcpiEvaluateObject interface 13442 1.1 jruoho where the subsystem would fault if the named object to be 13443 1.1 jruoho evaluated refered to a constant such as Zero, Ones, etc. 13444 1.1 jruoho 13445 1.1 jruoho Fixed a problem with IndexFields and BankFields where the 13446 1.1 jruoho subsystem would fault if the index, data, or bank registers were 13447 1.1 jruoho not defined in the same scope as the field itself. 13448 1.1 jruoho 13449 1.1 jruoho Added printf format string checking for compilers that support 13450 1.1 jruoho this feature. Corrected more than 50 instances of issues with 13451 1.1 jruoho format specifiers within invocations of ACPI_DEBUG_PRINT 13452 1.1 jruoho throughout the core subsystem code. 13453 1.1 jruoho 13454 1.1 jruoho The ASL "Revision" operator now returns the ACPI support level 13455 1.1 jruoho implemented in the core - the value "2" since the ACPI 2.0 support 13456 1.1 jruoho is more than 50% implemented. 13457 1.1 jruoho 13458 1.1 jruoho Enhanced the output of the AML debugger "dump namespace" command 13459 1.1 jruoho to output in a more human-readable form. 13460 1.1 jruoho 13461 1.1 jruoho Current core subsystem library code sizes are shown below. These 13462 1.1 jruoho 13463 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 13464 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 13465 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 13466 1.1 jruoho includes the full debug trace mechanism -- leading to a much 13467 1.1 jruoho 13468 1.1 jruoho larger code and data size. Note that these values will vary 13469 1.1 jruoho depending on the efficiency of the compiler and the compiler 13470 1.1 jruoho options used during generation. 13471 1.1 jruoho 13472 1.1 jruoho Previous Label (09_20_01): 13473 1.1 jruoho Non-Debug Version: 65K Code, 5K Data, 70K Total 13474 1.1 jruoho Debug Version: 138K Code, 58K Data, 196K Total 13475 1.1 jruoho 13476 1.1 jruoho This Label: 13477 1.1 jruoho 13478 1.1 jruoho Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total 13479 1.1 jruoho Debug Version: 136.7K Code, 57.4K Data, 194.2K Total 13480 1.1 jruoho 13481 1.1 jruoho Linux: 13482 1.1 jruoho 13483 1.1 jruoho Implemented a "Bad BIOS Blacklist" to track machines that have 13484 1.1 jruoho known ASL/AML problems. 13485 1.1 jruoho 13486 1.1 jruoho Enhanced the /proc interface for the thermal zone driver and added 13487 1.1 jruoho support for _HOT (the critical suspend trip point). The 'info' 13488 1.1 jruoho file now includes threshold/policy information, and allows setting 13489 1.1 jruoho of _SCP (cooling preference) and _TZP (polling frequency) values 13490 1.1 jruoho to the 'info' file. Examples: "echo tzp=5 > info" sets the polling 13491 1.1 jruoho frequency to 5 seconds, and "echo scp=1 > info" sets the cooling 13492 1.1 jruoho preference to the passive/quiet mode (if supported by the ASL). 13493 1.1 jruoho 13494 1.1 jruoho Implemented a workaround for a gcc bug that resuted in an OOPs 13495 1.1 jruoho when loading the control method battery driver. 13496 1.1 jruoho 13497 1.1 jruoho ---------------------------------------- 13498 1.1 jruoho Summary of changes for this label: 09_20_01 13499 1.1 jruoho 13500 1.1 jruoho ACPI CA Core Subsystem: 13501 1.1 jruoho 13502 1.1 jruoho The AcpiEnableEvent and AcpiDisableEvent interfaces have been 13503 1.1 jruoho modified to allow individual GPE levels to be flagged as wake- 13504 1.1 jruoho enabled (i.e., these GPEs are to remain enabled when the platform 13505 1.1 jruoho sleeps.) 13506 1.1 jruoho 13507 1.1 jruoho The AcpiEnterSleepState and AcpiLeaveSleepState interfaces now 13508 1.1 jruoho support wake-enabled GPEs. This means that upon entering the 13509 1.1 jruoho sleep state, all GPEs that are not wake-enabled are disabled. 13510 1.1 jruoho When leaving the sleep state, these GPEs are reenabled. 13511 1.1 jruoho 13512 1.1 jruoho A local double-precision divide/modulo module has been added to 13513 1.1 jruoho enhance portability to OS kernels where a 64-bit math library is 13514 1.1 jruoho not available. The new module is "utmath.c". 13515 1.1 jruoho 13516 1.1 jruoho Several optimizations have been made to reduce the use of CPU 13517 1.1 jruoho stack. Originally over 2K, the maximum stack usage is now below 13518 1.1 jruoho 2K at 1860 bytes (1.82k) 13519 1.1 jruoho 13520 1.1 jruoho Fixed a problem with the AcpiGetFirmwareTable interface where the 13521 1.1 jruoho root table pointer was not mapped into a logical address properly. 13522 1.1 jruoho 13523 1.1 jruoho Fixed a problem where a NULL pointer was being dereferenced in the 13524 1.1 jruoho interpreter code for the ASL Notify operator. 13525 1.1 jruoho 13526 1.1 jruoho Fixed a problem where the use of the ASL Revision operator 13527 1.1 jruoho returned an error. This operator now returns the current version 13528 1.1 jruoho of the ACPI CA core subsystem. 13529 1.1 jruoho 13530 1.1 jruoho Fixed a problem where objects passed as control method parameters 13531 1.1 jruoho to AcpiEvaluateObject were always deleted at method termination. 13532 1.1 jruoho However, these objects may end up being stored into the namespace 13533 1.1 jruoho by the called method. The object reference count mechanism was 13534 1.1 jruoho applied to these objects instead of a force delete. 13535 1.1 jruoho 13536 1.1 jruoho Fixed a problem where static strings or buffers (contained in the 13537 1.1 jruoho AML code) that are declared as package elements within the ASL 13538 1.1 jruoho code could cause a fault because the interpreter would attempt to 13539 1.1 jruoho delete them. These objects are now marked with the "static 13540 1.1 jruoho object" flag to prevent any attempt to delete them. 13541 1.1 jruoho 13542 1.1 jruoho Implemented an interpreter optimization to use operands directly 13543 1.1 jruoho from the state object instead of extracting the operands to local 13544 1.1 jruoho variables. This reduces stack use and code size, and improves 13545 1.1 jruoho performance. 13546 1.1 jruoho 13547 1.1 jruoho The module exxface.c was eliminated as it was an unnecessary extra 13548 1.1 jruoho layer of code. 13549 1.1 jruoho 13550 1.1 jruoho Current core subsystem library code sizes are shown below. These 13551 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 13552 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 13553 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 13554 1.1 jruoho includes the full debug trace mechanism -- leading to a much 13555 1.1 jruoho larger code and data size. Note that these values will vary 13556 1.1 jruoho depending on the efficiency of the compiler and the compiler 13557 1.1 jruoho options used during generation. 13558 1.1 jruoho 13559 1.1 jruoho Non-Debug Version: 65K Code, 5K Data, 70K Total 13560 1.1 jruoho (Previously 69K) Debug Version: 138K Code, 58K Data, 196K 13561 1.1 jruoho Total (Previously 195K) 13562 1.1 jruoho 13563 1.1 jruoho Linux: 13564 1.1 jruoho 13565 1.1 jruoho Support for ACPI 2.0 64-bit integers has been added. All ACPI 13566 1.1 jruoho Integer objects are now 64 bits wide 13567 1.1 jruoho 13568 1.1 jruoho All Acpi data types and structures are now in lower case. Only 13569 1.1 jruoho Acpi macros are upper case for differentiation. 13570 1.1 jruoho 13571 1.1 jruoho Documentation: 13572 1.1 jruoho 13573 1.1 jruoho Changes to the external interfaces as described above. 13574 1.1 jruoho 13575 1.1 jruoho ---------------------------------------- 13576 1.1 jruoho Summary of changes for this label: 08_31_01 13577 1.1 jruoho 13578 1.1 jruoho ACPI CA Core Subsystem: 13579 1.1 jruoho 13580 1.1 jruoho A bug with interpreter implementation of the ASL Divide operator 13581 1.1 jruoho was found and fixed. The implicit function return value (not the 13582 1.1 jruoho explicit store operands) was returning the remainder instead of 13583 1.1 jruoho the quotient. This was a longstanding bug and it fixes several 13584 1.1 jruoho known outstanding issues on various platforms. 13585 1.1 jruoho 13586 1.1 jruoho The ACPI_DEBUG_PRINT and function trace entry/exit macros have 13587 1.1 jruoho been further optimized for size. There are 700 invocations of the 13588 1.1 jruoho DEBUG_PRINT macro alone, so each optimization reduces the size of 13589 1.1 jruoho the debug version of the subsystem significantly. 13590 1.1 jruoho 13591 1.1 jruoho A stack trace mechanism has been implemented. The maximum stack 13592 1.1 jruoho usage is about 2K on 32-bit platforms. The debugger command "stat 13593 1.1 jruoho stack" will display the current maximum stack usage. 13594 1.1 jruoho 13595 1.1 jruoho All public symbols and global variables within the subsystem are 13596 1.1 jruoho now prefixed with the string "Acpi". This keeps all of the 13597 1.1 jruoho symbols grouped together in a kernel map, and avoids conflicts 13598 1.1 jruoho with other kernel subsystems. 13599 1.1 jruoho 13600 1.1 jruoho Most of the internal fixed lookup tables have been moved into the 13601 1.1 jruoho code segment via the const operator. 13602 1.1 jruoho 13603 1.1 jruoho Several enhancements have been made to the interpreter to both 13604 1.1 jruoho reduce the code size and improve performance. 13605 1.1 jruoho 13606 1.1 jruoho Current core subsystem library code sizes are shown below. These 13607 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 13608 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 13609 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 13610 1.1 jruoho includes the full debug trace mechanism which contains over 700 13611 1.1 jruoho invocations of the DEBUG_PRINT macro, 500 function entry macro 13612 1.1 jruoho invocations, and over 900 function exit macro invocations -- 13613 1.1 jruoho leading to a much larger code and data size. Note that these 13614 1.1 jruoho values will vary depending on the efficiency of the compiler and 13615 1.1 jruoho the compiler options used during generation. 13616 1.1 jruoho 13617 1.1 jruoho Non-Debug Version: 64K Code, 5K Data, 69K Total 13618 1.1 jruoho Debug Version: 137K Code, 58K Data, 195K Total 13619 1.1 jruoho 13620 1.1 jruoho Linux: 13621 1.1 jruoho 13622 1.1 jruoho Implemented wbinvd() macro, pending a kernel-wide definition. 13623 1.1 jruoho 13624 1.1 jruoho Fixed /proc/acpi/event to handle poll() and short reads. 13625 1.1 jruoho 13626 1.1 jruoho ASL Compiler, version X2026: 13627 1.1 jruoho 13628 1.1 jruoho Fixed a problem introduced in the previous label where the AML 13629 1.1 jruoho 13630 1.1 jruoho code emitted for package objects produced packages with zero 13631 1.1 jruoho length. 13632 1.1 jruoho 13633 1.1 jruoho ---------------------------------------- 13634 1.1 jruoho Summary of changes for this label: 08_16_01 13635 1.1 jruoho 13636 1.1 jruoho ACPI CA Core Subsystem: 13637 1.1 jruoho 13638 1.1 jruoho The following ACPI 2.0 ASL operators have been implemented in the 13639 1.1 jruoho AML interpreter (These are already supported by the Intel ASL 13640 1.1 jruoho compiler): ToDecimalString, ToHexString, ToString, ToInteger, and 13641 1.1 jruoho ToBuffer. Support for 64-bit AML constants is implemented in the 13642 1.1 jruoho AML parser, debugger, and disassembler. 13643 1.1 jruoho 13644 1.1 jruoho The internal memory tracking mechanism (leak detection code) has 13645 1.1 jruoho been upgraded to reduce the memory overhead (a separate tracking 13646 1.1 jruoho block is no longer allocated for each memory allocation), and now 13647 1.1 jruoho supports all of the internal object caches. 13648 1.1 jruoho 13649 1.1 jruoho The data structures and code for the internal object caches have 13650 1.1 jruoho been coelesced and optimized so that there is a single cache and 13651 1.1 jruoho memory list data structure and a single group of functions that 13652 1.1 jruoho implement generic cache management. This has reduced the code 13653 1.1 jruoho size in both the debug and release versions of the subsystem. 13654 1.1 jruoho 13655 1.1 jruoho The DEBUG_PRINT macro(s) have been optimized for size and replaced 13656 1.1 jruoho by ACPI_DEBUG_PRINT. The syntax for this macro is slightly 13657 1.1 jruoho different, because it generates a single call to an internal 13658 1.1 jruoho function. This results in a savings of about 90 bytes per 13659 1.1 jruoho invocation, resulting in an overall code and data savings of about 13660 1.1 jruoho 16% in the debug version of the subsystem. 13661 1.1 jruoho 13662 1.1 jruoho Linux: 13663 1.1 jruoho 13664 1.1 jruoho Fixed C3 disk corruption problems and re-enabled C3 on supporting 13665 1.1 jruoho machines. 13666 1.1 jruoho 13667 1.1 jruoho Integrated low-level sleep code by Patrick Mochel. 13668 1.1 jruoho 13669 1.1 jruoho Further tweaked source code Linuxization. 13670 1.1 jruoho 13671 1.1 jruoho Other minor fixes. 13672 1.1 jruoho 13673 1.1 jruoho ASL Compiler: 13674 1.1 jruoho 13675 1.1 jruoho Support for ACPI 2.0 variable length packages is fixed/completed. 13676 1.1 jruoho 13677 1.1 jruoho Fixed a problem where the optional length parameter for the ACPI 13678 1.1 jruoho 2.0 ToString operator. 13679 1.1 jruoho 13680 1.1 jruoho Fixed multiple extraneous error messages when a syntax error is 13681 1.1 jruoho detected within the declaration line of a control method. 13682 1.1 jruoho 13683 1.1 jruoho ---------------------------------------- 13684 1.1 jruoho Summary of changes for this label: 07_17_01 13685 1.1 jruoho 13686 1.1 jruoho ACPI CA Core Subsystem: 13687 1.1 jruoho 13688 1.1 jruoho Added a new interface named AcpiGetFirmwareTable to obtain any 13689 1.1 jruoho ACPI table via the ACPI signature. The interface can be called at 13690 1.1 jruoho any time during kernel initialization, even before the kernel 13691 1.1 jruoho virtual memory manager is initialized and paging is enabled. This 13692 1.1 jruoho allows kernel subsystems to obtain ACPI tables very early, even 13693 1.1 jruoho before the ACPI CA subsystem is initialized. 13694 1.1 jruoho 13695 1.1 jruoho Fixed a problem where Fields defined with the AnyAcc attribute 13696 1.1 jruoho could be resolved to the incorrect address under the following 13697 1.1 jruoho conditions: 1) the field width is larger than 8 bits and 2) the 13698 1.1 jruoho parent operation region is not defined on a DWORD boundary. 13699 1.1 jruoho 13700 1.1 jruoho Fixed a problem where the interpreter is not being locked during 13701 1.1 jruoho namespace initialization (during execution of the _INI control 13702 1.1 jruoho methods), causing an error when an attempt is made to release it 13703 1.1 jruoho later. 13704 1.1 jruoho 13705 1.1 jruoho ACPI 2.0 support in the AML Interpreter has begun and will be 13706 1.1 jruoho ongoing throughout the rest of this year. In this label, The Mod 13707 1.1 jruoho operator is implemented. 13708 1.1 jruoho 13709 1.1 jruoho Added a new data type to contain full PCI addresses named 13710 1.1 jruoho ACPI_PCI_ID. This structure contains the PCI Segment, Bus, Device, 13711 1.1 jruoho and Function values. 13712 1.1 jruoho 13713 1.1 jruoho Linux: 13714 1.1 jruoho 13715 1.1 jruoho Enhanced the Linux version of the source code to change most 13716 1.1 jruoho capitalized ACPI type names to lowercase. For example, all 13717 1.1 jruoho instances of ACPI_STATUS are changed to acpi_status. This will 13718 1.1 jruoho result in a large diff, but the change is strictly cosmetic and 13719 1.1 jruoho aligns the CA code closer to the Linux coding standard. 13720 1.1 jruoho 13721 1.1 jruoho OSL Interfaces: 13722 1.1 jruoho 13723 1.1 jruoho The interfaces to the PCI configuration space have been changed to 13724 1.1 jruoho add the PCI Segment number and to split the single 32-bit combined 13725 1.1 jruoho DeviceFunction field into two 16-bit fields. This was 13726 1.1 jruoho accomplished by moving the four values that define an address in 13727 1.1 jruoho PCI configuration space (segment, bus, device, and function) to 13728 1.1 jruoho the new ACPI_PCI_ID structure. 13729 1.1 jruoho 13730 1.1 jruoho The changes to the PCI configuration space interfaces led to a 13731 1.1 jruoho reexamination of the complete set of address space access 13732 1.1 jruoho interfaces for PCI, I/O, and Memory. The previously existing 18 13733 1.1 jruoho interfaces have proven difficult to maintain (any small change 13734 1.1 jruoho must be propagated across at least 6 interfaces) and do not easily 13735 1.1 jruoho allow for future expansion to 64 bits if necessary. Also, on some 13736 1.1 jruoho systems, it would not be appropriate to demultiplex the access 13737 1.1 jruoho width (8, 16, 32,or 64) before calling the OSL if the 13738 1.1 jruoho corresponding native OS interfaces contain a similar access width 13739 1.1 jruoho parameter. For these reasons, the 18 address space interfaces 13740 1.1 jruoho have been replaced by these 6 new ones: 13741 1.1 jruoho 13742 1.1 jruoho AcpiOsReadPciConfiguration 13743 1.1 jruoho AcpiOsWritePciConfiguration 13744 1.1 jruoho AcpiOsReadMemory 13745 1.1 jruoho AcpiOsWriteMemory 13746 1.1 jruoho AcpiOsReadPort 13747 1.1 jruoho AcpiOsWritePort 13748 1.1 jruoho 13749 1.1 jruoho Added a new interface named AcpiOsGetRootPointer to allow the OSL 13750 1.1 jruoho to perform the platform and/or OS-specific actions necessary to 13751 1.1 jruoho obtain the ACPI RSDP table pointer. On IA-32 platforms, this 13752 1.1 jruoho interface will simply call down to the CA core to perform the low- 13753 1.1 jruoho memory search for the table. On IA-64, the RSDP is obtained from 13754 1.1 jruoho EFI. Migrating this interface to the OSL allows the CA core to 13755 1.1 jruoho 13756 1.1 jruoho remain OS and platform independent. 13757 1.1 jruoho 13758 1.1 jruoho Added a new interface named AcpiOsSignal to provide a generic 13759 1.1 jruoho "function code and pointer" interface for various miscellaneous 13760 1.1 jruoho signals and notifications that must be made to the host OS. The 13761 1.1 jruoho first such signals are intended to support the ASL Fatal and 13762 1.1 jruoho Breakpoint operators. In the latter case, the AcpiOsBreakpoint 13763 1.1 jruoho interface has been obsoleted. 13764 1.1 jruoho 13765 1.1 jruoho The definition of the AcpiFormatException interface has been 13766 1.1 jruoho changed to simplify its use. The caller no longer must supply a 13767 1.1 jruoho buffer to the call; A pointer to a const string is now returned 13768 1.1 jruoho directly. This allows the call to be easily used in printf 13769 1.1 jruoho statements, etc. since the caller does not have to manage a local 13770 1.1 jruoho buffer. 13771 1.1 jruoho 13772 1.1 jruoho 13773 1.1 jruoho ASL Compiler, Version X2025: 13774 1.1 jruoho 13775 1.1 jruoho The ACPI 2.0 Switch/Case/Default operators have been implemented 13776 1.1 jruoho and are fully functional. They will work with all ACPI 1.0 13777 1.1 jruoho interpreters, since the operators are simply translated to If/Else 13778 1.1 jruoho pairs. 13779 1.1 jruoho 13780 1.1 jruoho The ACPI 2.0 ElseIf operator is implemented and will also work 13781 1.1 jruoho with 1.0 interpreters, for the same reason. 13782 1.1 jruoho 13783 1.1 jruoho Implemented support for ACPI 2.0 variable-length packages. These 13784 1.1 jruoho packages have a separate opcode, and their size is determined by 13785 1.1 jruoho the interpreter at run-time. 13786 1.1 jruoho 13787 1.1 jruoho Documentation The ACPI CA Programmer Reference has been updated to 13788 1.1 jruoho reflect the new interfaces and changes to existing interfaces. 13789 1.1 jruoho 13790 1.1 jruoho ------------------------------------------ 13791 1.1 jruoho Summary of changes for this label: 06_15_01 13792 1.1 jruoho 13793 1.1 jruoho ACPI CA Core Subsystem: 13794 1.1 jruoho 13795 1.1 jruoho Fixed a problem where a DWORD-accessed field within a Buffer 13796 1.1 jruoho object would get its byte address inadvertently rounded down to 13797 1.1 jruoho the nearest DWORD. Buffers are always Byte-accessible. 13798 1.1 jruoho 13799 1.1 jruoho ASL Compiler, version X2024: 13800 1.1 jruoho 13801 1.1 jruoho Fixed a problem where the Switch() operator would either fault or 13802 1.1 jruoho hang the compiler. Note however, that the AML code for this ACPI 13803 1.1 jruoho 2.0 operator is not yet implemented. 13804 1.1 jruoho 13805 1.1 jruoho Compiler uses the new AcpiOsGetTimer interface to obtain compile 13806 1.1 jruoho timings. 13807 1.1 jruoho 13808 1.1 jruoho Implementation of the CreateField operator automatically converts 13809 1.1 jruoho a reference to a named field within a resource descriptor from a 13810 1.1 jruoho byte offset to a bit offset if required. 13811 1.1 jruoho 13812 1.1 jruoho Added some missing named fields from the resource descriptor 13813 1.1 jruoho support. These are the names that are automatically created by the 13814 1.1 jruoho compiler to reference fields within a descriptor. They are only 13815 1.1 jruoho valid at compile time and are not passed through to the AML 13816 1.1 jruoho interpreter. 13817 1.1 jruoho 13818 1.1 jruoho Resource descriptor named fields are now typed as Integers and 13819 1.1 jruoho subject to compile-time typechecking when used in expressions. 13820 1.1 jruoho 13821 1.1 jruoho ------------------------------------------ 13822 1.1 jruoho Summary of changes for this label: 05_18_01 13823 1.1 jruoho 13824 1.1 jruoho ACPI CA Core Subsystem: 13825 1.1 jruoho 13826 1.1 jruoho Fixed a couple of problems in the Field support code where bits 13827 1.1 jruoho from adjacent fields could be returned along with the proper field 13828 1.1 jruoho bits. Restructured the field support code to improve performance, 13829 1.1 jruoho readability and maintainability. 13830 1.1 jruoho 13831 1.1 jruoho New DEBUG_PRINTP macro automatically inserts the procedure name 13832 1.1 jruoho into the output, saving hundreds of copies of procedure name 13833 1.1 jruoho strings within the source, shrinking the memory footprint of the 13834 1.1 jruoho debug version of the core subsystem. 13835 1.1 jruoho 13836 1.1 jruoho Source Code Structure: 13837 1.1 jruoho 13838 1.1 jruoho The source code directory tree was restructured to reflect the 13839 1.1 jruoho current organization of the component architecture. Some files 13840 1.1 jruoho and directories have been moved and/or renamed. 13841 1.1 jruoho 13842 1.1 jruoho Linux: 13843 1.1 jruoho 13844 1.1 jruoho Fixed leaking kacpidpc processes. 13845 1.1 jruoho 13846 1.1 jruoho Fixed queueing event data even when /proc/acpi/event is not 13847 1.1 jruoho opened. 13848 1.1 jruoho 13849 1.1 jruoho ASL Compiler, version X2020: 13850 1.1 jruoho 13851 1.1 jruoho Memory allocation performance enhancement - over 24X compile time 13852 1.1 jruoho improvement on large ASL files.

This was required 14079 1.1 jruoho for the deadlock detection code. Defined to return a non-zero, 32- 14080 1.1 jruoho bit thread ID for the currently executing thread. May be a non- 14081 1.1 jruoho zero constant integer on single-thread systems. 14082 1.1 jruoho 14083 1.1 jruoho Implemented deadlock detection for internal subsystem mutexes. We 14084 1.1 jruoho may add conditional compilation for this code (debug only) later. 14085 1.1 jruoho 14086 1.1 jruoho ASL/AML Mutex object semantics are now fully supported. This 14087 1.1 jruoho includes multiple acquires/releases by owner and support for the 14088 1.1 jruoho 14089 1.1 jruoho Mutex SyncLevel parameter. 14090 1.1 jruoho 14091 1.1 jruoho A new "Force Release" mechanism automatically frees all ASL 14092 1.1 jruoho Mutexes that have been acquired but not released when a thread 14093 1.1 jruoho exits the interpreter. This forces conformance to the ACPI spec 14094 1.1 jruoho ("All mutexes must be released when an invocation exits") and 14095 1.1 jruoho prevents deadlocked ASL threads. This mechanism can be expanded 14096 1.1 jruoho (later) to monitor other resource acquisitions if OEM ASL code 14097 1.1 jruoho continues to misbehave (which it will). 14098 1.1 jruoho 14099 1.1 jruoho Several new ACPI exception codes have been added for the Mutex 14100 1.1 jruoho support. 14101 1.1 jruoho 14102 1.1 jruoho Recursive method calls are now allowed and supported (the ACPI 14103 1.1 jruoho spec does in fact allow recursive method calls.) The number of 14104 1.1 jruoho recursive calls is subject to the restrictions imposed by the 14105 1.1 jruoho SERIALIZED method keyword and SyncLevel (ACPI 2.0) method 14106 1.1 jruoho parameter. 14107 1.1 jruoho 14108 1.1 jruoho Implemented support for the SyncLevel parameter for control 14109 1.1 jruoho methods (ACPI 2.0 feature) 14110 1.1 jruoho 14111 1.1 jruoho Fixed a deadlock problem when multiple threads attempted to use 14112 1.1 jruoho the interpreter. 14113 1.1 jruoho 14114 1.1 jruoho Fixed a problem where the string length of a String package 14115 1.1 jruoho element was not always set in a package returned from 14116 1.1 jruoho AcpiEvaluateObject. 14117 1.1 jruoho 14118 1.1 jruoho Fixed a problem where the length of a String package element was 14119 1.1 jruoho not always included in the length of the overall package returned 14120 1.1 jruoho from AcpiEvaluateObject. 14121 1.1 jruoho 14122 1.1 jruoho Added external interfaces (Acpi*) to the ACPI debug memory 14123 1.1 jruoho manager. This manager keeps a list of all outstanding 14124 1.1 jruoho allocations, and can therefore detect memory leaks and attempts to 14125 1.1 jruoho free memory blocks more than once. Useful for code such as the 14126 1.1 jruoho power manager, etc. May not be appropriate for device drivers. 14127 1.1 jruoho Performance with the debug code enabled is slow. 14128 1.1 jruoho 14129 1.1 jruoho The ACPI Global Lock is now an optional hardware element. 14130 1.1 jruoho 14131 1.1 jruoho ASL Compiler Version X2015: 14132 1.1 jruoho 14133 1.1 jruoho Integrated changes to allow the compiler to be generated on 14134 1.1 jruoho multiple platforms. 14135 1.1 jruoho 14136 1.1 jruoho Linux makefile added to generate the compiler on Linux 14137 1.1 jruoho 14138 1.1 jruoho Source Code: 14139 1.1 jruoho 14140 1.1 jruoho All platform-specific headers have been moved to their own 14141 1.1 jruoho subdirectory, Include/Platform. 14142 1.1 jruoho 14143 1.1 jruoho New source file added, Interpreter/ammutex.c 14144 1.1 jruoho 14145 1.1 jruoho New header file, Include/acstruct.h 14146 1.1 jruoho 14147 1.1 jruoho Documentation: 14148 1.1 jruoho 14149 1.1 jruoho The programmer reference has been updated for the following new 14150 1.1 jruoho interfaces: AcpiOsGetThreadId AcpiAllocate AcpiCallocate AcpiFree 14151 1.1 jruoho 14152 1.1 jruoho ------------------------------------------ 14153 1.1 jruoho Summary of changes for this label: 02_08_01 14154 1.1 jruoho 14155 1.1 jruoho Core ACPI CA Subsystem: Fixed a problem where an error was 14156 1.1 jruoho incorrectly returned if the return resource buffer was larger than 14157 1.1 jruoho the actual data (in the resource interfaces). 14158 1.1 jruoho 14159 1.1 jruoho References to named objects within packages are resolved to the 14160 1.1 jruoho 14161 1.1 jruoho full pathname string before packages are returned directly (via 14162 1.1 jruoho the AcpiEvaluateObject interface) or indirectly via the resource 14163 1.1 jruoho interfaces. 14164 1.1 jruoho 14165 1.1 jruoho Linux OS Services Layer (OSL): 14166 1.1 jruoho 14167 1.1 jruoho Improved /proc battery interface. 14168 1.1 jruoho 14169 1.1 jruoho 14170 1.1 jruoho Added C-state debugging output and other miscellaneous fixes. 14171 1.1 jruoho 14172 1.1 jruoho ASL Compiler Version X2014: 14173 1.1 jruoho 14174 1.1 jruoho All defined method arguments can now be used as local variables, 14175 1.1 jruoho including the ones that are not actually passed in as parameters. 14176 1.1 jruoho The compiler tracks initialization of the arguments and issues an 14177 1.1 jruoho exception if they are used without prior assignment (just like 14178 1.1 jruoho locals). 14179 1.1 jruoho 14180 1.1 jruoho The -o option now specifies a filename prefix that is used for all 14181 1.1 jruoho output files, including the AML output file.

This 14253 1.1 jruoho prevents the use of invalid objects (such as using a Package where 14254 1.1 jruoho an Integer is required) at compile time instead of at interpreter 14255 1.1 jruoho run-time. 14256 1.1 jruoho 2. The ASL source line is printed with ALL errors and warnings. 14257 1.1 jruoho 3. Bug fix for source EOF without final linefeed. 14258 1.1 jruoho 4. Debug option is split into a parse trace and a namespace trace. 14259 1.1 jruoho 5. Namespace output option (-n) includes initial values for 14260 1.1 jruoho integers and strings. 14261 1.1 jruoho 6. Parse-only option added for quick syntax checking. 14262 1.1 jruoho 7. Compiler checks for duplicate ACPI name declarations 14263 1.1 jruoho 14264 1.1 jruoho Version X2012: 14265 1.1 jruoho 1. Relaxed typechecking to allow interchangeability between 14266 1.1 jruoho strings, integers, and buffers. These types are now converted by 14267 1.1 jruoho the interpreter at runtime. 14268 1.1 jruoho 2. Compiler reports time taken by each internal subsystem in the 14269 1.1 jruoho debug output file. 14270 1.1 jruoho 14271 1.1 jruoho 14272 1.1 jruoho ------------------------------------------ 14273 1.1 jruoho Summary of changes for this label: 12_14_00 14274 1.1 jruoho 14275 1.1 jruoho ASL Compiler: 14276 1.1 jruoho 14277 1.1 jruoho This is the first official release of the compiler. Since the 14278 1.1 jruoho compiler requires elements of the Core Subsystem, this label 14279 1.1 jruoho synchronizes everything. 14280 1.1 jruoho 14281 1.1 jruoho ------------------------------------------ 14282 1.1 jruoho Summary of changes for this label: 12_08_00 14283 1.1 jruoho 14284 1.1 jruoho 14285 1.1 jruoho Fixed a problem where named references within the ASL definition 14286 1.1 jruoho of both OperationRegions and CreateXXXFields did not work 14287 1.1 jruoho properly. The symptom was an AE_AML_OPERAND_TYPE during 14288 1.1 jruoho initialization of the region/field. This is similar (but not 14289 1.1 jruoho related internally) to the problem that was fixed in the last 14290 1.1 jruoho label. 14291 1.1 jruoho 14292 1.1 jruoho Implemented both 32-bit and 64-bit support for the BCD ASL 14293 1.1 jruoho functions ToBCD and FromBCD. 14294 1.1 jruoho 14295 1.1 jruoho Updated all legal headers to include "2000" in the copyright 14296 1.1 jruoho years. 14297 1.1 jruoho 14298 1.1 jruoho ------------------------------------------ 14299 1.1 jruoho Summary of changes for this label: 12_01_00 14300 1.1 jruoho 14301 1.1 jruoho Fixed a problem where method invocations within the ASL definition 14302 1.1 jruoho of both OperationRegions and CreateXXXFields did not work 14303 1.1 jruoho properly. The symptom was an AE_AML_OPERAND_TYPE during 14304 1.1 jruoho initialization of the region/field: 14305 1.1 jruoho 14306 1.1 jruoho nsinit-0209: AE_AML_OPERAND_TYPE while getting region arguments 14307 1.1 jruoho [DEBG] ammonad-0284: Exec_monadic2_r/Not: bad operand(s) 14308 1.1 jruoho (0x3005) 14309 1.1 jruoho 14310 1.1 jruoho Fixed a problem where operators with more than one nested 14311 1.1 jruoho subexpression would fail. The symptoms were varied, by mostly 14312 1.1 jruoho AE_AML_OPERAND_TYPE errors. This was actually a rather serious 14313 1.1 jruoho problem that has gone unnoticed until now. 14314 1.1 jruoho 14315 1.1 jruoho Subtract (Add (1,2), Multiply (3,4)) 14316 1.1 jruoho 14317 1.1 jruoho Fixed a problem where AcpiGetHandle didn't quite get fixed in the 14318 1.1 jruoho previous build (The prefix part of a relative path was handled 14319 1.1 jruoho incorrectly). 14320 1.1 jruoho 14321 1.1 jruoho Fixed a problem where Operation Region initialization failed if 14322 1.1 jruoho the operation region name was a "namepath" instead of a simple 14323 1.1 jruoho "nameseg". Symptom was an AE_NO_OPERAND error. 14324 1.1 jruoho 14325 1.1 jruoho Fixed a problem where an assignment to a local variable via the 14326 1.1 jruoho indirect RefOf mechanism only worked for the first such 14327 1.1 jruoho assignment. Subsequent assignments were ignored. 14328 1.1 jruoho 14329 1.1 jruoho ------------------------------------------ 14330 1.1 jruoho Summary of changes for this label: 11_15_00 14331 1.1 jruoho 14332 1.1 jruoho ACPI 2.0 table support with backwards support for ACPI 1.0 and the 14333 1.1 jruoho 0.71 extensions. Note: although we can read ACPI 2.0 BIOS tables, 14334 1.1 jruoho the AML interpreter does NOT have support for the new 2.0 ASL 14335 1.1 jruoho grammar terms at this time. 14336 1.1 jruoho 14337 1.1 jruoho All ACPI hardware access is via the GAS structures in the ACPI 2.0 14338 1.1 jruoho FADT. 14339 1.1 jruoho 14340 1.1 jruoho All physical memory addresses across all platforms are now 64 bits 14341 1.1 jruoho wide. Logical address width remains dependent on the platform 14342 1.1 jruoho (i.e., "void *"). 14343 1.1 jruoho 14344 1.1 jruoho AcpiOsMapMemory interface changed to a 64-bit physical address. 14345 1.1 jruoho 14346 1.1 jruoho The AML interpreter integer size is now 64 bits, as per the ACPI 14347 1.1 jruoho 2.0 specification. 14348 1.1 jruoho 14349 1.1 jruoho For backwards compatibility with ACPI 1.0, ACPI tables with a 14350 1.1 jruoho revision number less than 2 use 32-bit integers only. 14351 1.1 jruoho 14352 1.1 jruoho Fixed a problem where the evaluation of OpRegion operands did not 14353 1.1 jruoho always resolve them to numbers properly. 14354 1.1 jruoho 14355 1.1 jruoho ------------------------------------------ 14356 1.1 jruoho Summary of changes for this label: 10_20_00 14357 1.1 jruoho 14358 1.1 jruoho Fix for CBN_._STA issue. This fix will allow correct access to 14359 1.1 jruoho CBN_ OpRegions when the _STA returns 0x8. 14360 1.1 jruoho 14361 1.1 jruoho Support to convert ACPI constants (Ones, Zeros, One) to actual 14362 1.1 jruoho values before a package object is returned 14363 1.1 jruoho 14364 1.1 jruoho Fix for method call as predicate to if/while construct causing 14365 1.1 jruoho incorrect if/while behavior 14366 1.1 jruoho 14367 1.1 jruoho Fix for Else block package lengths sometimes calculated wrong (if 14368 1.1 jruoho block > 63 bytes) 14369 1.1 jruoho 14370 1.1 jruoho Fix for Processor object length field, was always zero 14371 1.1 jruoho 14372 1.1 jruoho Table load abort if FACP sanity check fails 14373 1.1 jruoho 14374 1.1 jruoho Fix for problem with Scope(name) if name already exists 14375 1.1 jruoho 14376 1.1 jruoho Warning emitted if a named object referenced cannot be found 14377 1.1 jruoho (resolved) during method execution. 14378 1.1 jruoho 14379 1.1 jruoho 14380 1.1 jruoho 14381 1.1 jruoho 14382 1.1 jruoho 14383 1.1 jruoho ------------------------------------------ 14384 1.1 jruoho Summary of changes for this label: 9_29_00 14385 1.1 jruoho 14386 1.1 jruoho New table initialization interfaces: AcpiInitializeSubsystem no 14387 1.1 jruoho longer has any parameters AcpiFindRootPointer - Find the RSDP (if 14388 1.1 jruoho necessary) AcpiLoadTables (RSDP) - load all tables found at RSDP- 14389 1.1 jruoho >RSDT Obsolete Interfaces AcpiLoadFirmwareTables - replaced by 14390 1.1 jruoho AcpiLoadTables 14391 1.1 jruoho 14392 1.1 jruoho Note: These interface changes require changes to all existing OSDs 14393 1.1 jruoho 14394 1.1 jruoho The PCI_Config default address space handler is always installed 14395 1.1 jruoho at the root namespace object. 14396 1.1 jruoho 14397 1.1 jruoho ------------------------------------------- 14398 1.1 jruoho Summary of changes for this label: 09_15_00 14399 1.1 jruoho 14400 1.1 jruoho The new initialization architecture is implemented. New 14401 1.1 jruoho interfaces are: AcpiInitializeSubsystem (replaces AcpiInitialize) 14402 1.1 jruoho AcpiEnableSubsystem Obsolete Interfaces: AcpiLoadNamespace 14403 1.1 jruoho 14404 1.1 jruoho (Namespace is automatically loaded when a table is loaded) 14405 1.1 jruoho 14406 1.1 jruoho The ACPI_OPERAND_OBJECT has been optimized to shrink its size from 14407 1.1 jruoho 52 bytes to 32 bytes. There is usually one of these for every 14408 1.1 jruoho namespace object, so the memory savings is significant. 14409 1.1 jruoho 14410 1.1 jruoho Implemented just-in-time evaluation of the CreateField operators. 14411 1.1 jruoho 14412 1.1 jruoho Bug fixes for IA-64 support have been integrated. 14413 1.1 jruoho 14414 1.1 jruoho Additional code review comments have been implemented 14415 1.1 jruoho 14416 1.1 jruoho The so-called "third pass parse" has been replaced by a final walk 14417 1.1 jruoho through the namespace to initialize all operation regions (address 14418 1.1 jruoho spaces) and fields that have not yet been initialized during the 14419 1.1 jruoho execution of the various _INI and REG methods. 14420 1.1 jruoho 14421 1.1 jruoho New file - namespace/nsinit.c 14422 1.1 jruoho 14423 1.1 jruoho ------------------------------------------- 14424 1.1 jruoho Summary of changes for this label: 09_01_00 14425 1.1 jruoho 14426 1.1 jruoho Namespace manager data structures have been reworked to change the 14427 1.1 jruoho primary object from a table to a single object. This has 14428 1.1 jruoho resulted in dynamic memory savings of 3X within the namespace and 14429 1.1 jruoho 2X overall in the ACPI CA subsystem. 14430 1.1 jruoho 14431 1.1 jruoho Fixed problem where the call to AcpiEvFindPciRootBuses was 14432 1.1 jruoho inadvertently left commented out. 14433 1.1 jruoho 14434 1.1 jruoho Reduced the warning count when generating the source with the GCC 14435 1.1 jruoho compiler. 14436 1.1 jruoho 14437 1.1 jruoho Revision numbers added to each module header showing the 14438 1.1 jruoho SourceSafe version of the file. Please refer to this version 14439 1.1 jruoho number when giving us feedback or comments on individual modules. 14440 1.1 jruoho 14441 1.1 jruoho The main object types within the subsystem have been renamed to 14442 1.1 jruoho clarify their purpose: 14443 1.1 jruoho 14444 1.1 jruoho ACPI_INTERNAL_OBJECT -> ACPI_OPERAND_OBJECT 14445 1.1 jruoho ACPI_GENERIC_OP -> ACPI_PARSE_OBJECT 14446 1.1 jruoho ACPI_NAME_TABLE_ENTRY -> ACPI_NAMESPACE_NODE 14447 1.1 jruoho 14448 1.1 jruoho NOTE: no changes to the initialization sequence are included in 14449 1.1 jruoho this label. 14450 1.1 jruoho 14451 1.1 jruoho ------------------------------------------- 14452 1.1 jruoho Summary of changes for this label: 08_23_00 14453 1.1 jruoho 14454 1.1 jruoho Fixed problem where TerminateControlMethod was being called 14455 1.1 jruoho multiple times per method 14456 1.1 jruoho 14457 1.1 jruoho Fixed debugger problem where single stepping caused a semaphore to 14458 1.1 jruoho be oversignalled 14459 1.1 jruoho 14460 1.1 jruoho Improved performance through additional parse object caching - 14461 1.1 jruoho added ACPI_EXTENDED_OP type 14462 1.1 jruoho 14463 1.1 jruoho ------------------------------------------- 14464 1.1 jruoho Summary of changes for this label: 08_10_00 14465 1.1 jruoho 14466 1.1 jruoho Parser/Interpreter integration: Eliminated the creation of 14467 1.1 jruoho complete parse trees for ACPI tables and control methods. 14468 1.1 jruoho Instead, parse subtrees are created and then deleted as soon as 14469 1.1 jruoho they are processed (Either entered into the namespace or executed 14470 1.1 jruoho by the interpreter). This reduces the use of dynamic kernel 14471 1.1 jruoho memory significantly. (about 10X) 14472 1.1 jruoho 14473 1.1 jruoho Exception codes broken into classes and renumbered. Be sure to 14474 1.1 jruoho recompile all code that includes acexcep.h. Hopefully we won't 14475 1.1 jruoho have to renumber the codes again now that they are split into 14476 1.1 jruoho classes (environment, programmer, AML code, ACPI table, and 14477 1.1 jruoho internal). 14478 1.1 jruoho 14479 1.1 jruoho Fixed some additional alignment issues in the Resource Manager 14480 1.1 jruoho subcomponent 14481 1.1 jruoho 14482 1.1 jruoho Implemented semaphore tracking in the AcpiExec utility, and fixed 14483 1.1 jruoho several places where mutexes/semaphores were being unlocked 14484 1.1 jruoho without a corresponding lock operation. There are no known 14485 1.1 jruoho semaphore or mutex "leaks" at this time. 14486 1.1 jruoho 14487 1.1 jruoho Fixed the case where an ASL Return operator is used to return an 14488 1.1 jruoho unnamed package. 14489 1.1 jruoho 14490 1.1 jruoho ------------------------------------------- 14491 1.1 jruoho Summary of changes for this label: 07_28_00 14492 1.1 jruoho 14493 1.1 jruoho Fixed a problem with the way addresses were calculated in 14494 1.1 jruoho AcpiAmlReadFieldData() and AcpiAmlWriteFieldData(). This problem 14495 1.1 jruoho manifested itself when a Field was created with WordAccess or 14496 1.1 jruoho DwordAccess, but the field unit defined within the Field was less 14497 1.1 jruoho 14498 1.1 jruoho than a Word or Dword. 14499 1.1 jruoho 14500 1.1 jruoho Fixed a problem in AmlDumpOperands() module's loop to pull 14501 1.1 jruoho operands off of the operand stack to display information. The 14502 1.1 jruoho problem manifested itself as a TLB error on 64-bit systems when 14503 1.1 jruoho accessing an operand stack with two or more operands. 14504 1.1 jruoho 14505 1.1 jruoho Fixed a problem with the PCI configuration space handlers where 14506 1.1 jruoho context was getting confused between accesses. This required a 14507 1.1 jruoho change to the generic address space handler and address space 14508 1.1 jruoho setup definitions. Handlers now get both a global handler context 14509 1.1 jruoho (this is the one passed in by the user when executing 14510 1.1 jruoho AcpiInstallAddressSpaceHandler() and a specific region context 14511 1.1 jruoho that is unique to each region (For example, the _ADR, _SEG and 14512 1.1 jruoho _BBN values associated with a specific region). The generic 14513 1.1 jruoho function definitions have changed to the following: 14514 1.1 jruoho 14515 1.1 jruoho typedef ACPI_STATUS (*ADDRESS_SPACE_HANDLER) ( UINT32 Function, 14516 1.1 jruoho UINT32 Address, UINT32 BitWidth, UINT32 *Value, void 14517 1.1 jruoho *HandlerContext, // This used to be void *Context void 14518 1.1 jruoho *RegionContext); // This is an additional parameter 14519 1.1 jruoho 14520 1.1 jruoho typedef ACPI_STATUS (*ADDRESS_SPACE_SETUP) ( ACPI_HANDLE 14521 1.1 jruoho RegionHandle, UINT32 Function, void *HandlerContext, void 14522 1.1 jruoho **RegionContext); // This used to be **ReturnContext 14523 1.1 jruoho 14524 1.1 jruoho ------------------------------------------- 14525 1.1 jruoho Summary of changes for this label: 07_21_00 14526 1.1 jruoho 14527 1.1 jruoho Major file consolidation and rename. All files within the 14528 1.1 jruoho interpreter have been renamed as well as most header files. This 14529 1.1 jruoho was done to prevent collisions with existing files in the host 14530 1.1 jruoho OSs -- filenames such as "config.h" and "global.h" seem to be 14531 1.1 jruoho quite common. The VC project files have been updated. All 14532 1.1 jruoho makefiles will require modification. 14533 1.1 jruoho 14534 1.1 jruoho The parser/interpreter integration continues in Phase 5 with the 14535 1.1 jruoho implementation of a complete 2-pass parse (the AML is parsed 14536 1.1 jruoho twice) for each table; This avoids the construction of a huge 14537 1.1 jruoho parse tree and therefore reduces the amount of dynamic memory 14538 1.1 jruoho required by the subsystem. Greater use of the parse object cache 14539 1.1 jruoho means that performance is unaffected. 14540 1.1 jruoho 14541 1.1 jruoho Many comments from the two code reviews have been rolled in. 14542 1.1 jruoho 14543 1.1 jruoho The 64-bit alignment support is complete. 14544 1.1 jruoho 14545 1.1 jruoho ------------------------------------------- 14546 1.1 jruoho Summary of changes for this label: 06_30_00 14547 1.1 jruoho 14548 1.1 jruoho With a nod and a tip of the hat to the technology of yesteryear, 14549 1.1 jruoho we've added support in the source code for 80 column output 14550 1.1 jruoho devices. The code is now mostly constrained to 80 columns or 14551 1.1 jruoho less to support environments and editors that 1) cannot display 14552 1.1 jruoho or print more than 80 characters on a single line, and 2) cannot 14553 1.1 jruoho disable line wrapping. 14554 1.1 jruoho 14555 1.1 jruoho A major restructuring of the namespace data structure has been 14556 1.1 jruoho completed. The result is 1) cleaner and more 14557 1.1 jruoho understandable/maintainable code, and 2) a significant reduction 14558 1.1 jruoho in the dynamic memory requirement for each named ACPI object 14559 1.1 jruoho (almost half). 14560 1.1 jruoho 14561 1.1 jruoho ------------------------------------------- 14562 1.1 jruoho Summary of changes for this label: 06_23_00 14563 1.1 jruoho 14564 1.1 jruoho Linux support has been added. In order to obtain approval to get 14565 1.1 jruoho the ACPI CA subsystem into the Linux kernel, we've had to make 14566 1.1 jruoho quite a few changes to the base subsystem that will affect all 14567 1.1 jruoho users (all the changes are generic and OS- independent). The 14568 1.1 jruoho effects of these global changes have been somewhat far reaching. 14569 1.1 jruoho Files have been merged and/or renamed and interfaces have been 14570 1.1 jruoho renamed. The major changes are described below. 14571 1.1 jruoho 14572 1.1 jruoho Osd* interfaces renamed to AcpiOs* to eliminate namespace 14573 1.1 jruoho pollution/confusion within our target kernels. All OSD 14574 1.1 jruoho interfaces must be modified to match the new naming convention. 14575 1.1 jruoho 14576 1.1 jruoho Files merged across the subsystem. A number of the smaller source 14577 1.1 jruoho and header files have been merged to reduce the file count and 14578 1.1 jruoho increase the density of the existing files. There are too many 14579 1.1 jruoho to list here. In general, makefiles that call out individual 14580 1.1 jruoho files will require rebuilding. 14581 1.1 jruoho 14582 1.1 jruoho Interpreter files renamed. All interpreter files now have the 14583 1.1 jruoho prefix am* instead of ie* and is*. 14584 1.1 jruoho 14585 1.1 jruoho Header files renamed: The acapi.h file is now acpixf.h. The 14586 1.1 jruoho acpiosd.h file is now acpiosxf.h. We are removing references to 14587 1.1 jruoho the acronym "API" since it is somewhat windowsy. The new name is 14588 1.1 jruoho "external interface" or xface or xf in the filenames.j 14589 1.1 jruoho 14590 1.1 jruoho 14591 1.1 jruoho All manifest constants have been forced to upper case (some were 14592 1.1 jruoho mixed case.) Also, the string "ACPI_" has been prepended to many 14593 1.1 jruoho (not all) of the constants, typedefs, and structs. 14594 1.1 jruoho 14595 1.1 jruoho The globals "DebugLevel" and "DebugLayer" have been renamed 14596 1.1 jruoho "AcpiDbgLevel" and "AcpiDbgLayer" respectively. 14597 1.1 jruoho 14598 1.1 jruoho All other globals within the subsystem are now prefixed with 14599 1.1 jruoho "AcpiGbl_" Internal procedures within the subsystem are now 14600 1.1 jruoho prefixed with "Acpi" (with only a few exceptions). The original 14601 1.1 jruoho two-letter abbreviation for the subcomponent remains after "Acpi" 14602 1.1 jruoho - for example, CmCallocate became AcpiCmCallocate. 14603 1.1 jruoho 14604 1.1 jruoho Added a source code translation/conversion utility. Used to 14605 1.1 jruoho generate the Linux source code, it can be modified to generate 14606 1.1 jruoho other types of source as well. Can also be used to cleanup 14607 1.1 jruoho existing source by removing extraneous spaces and blank lines. 14608 1.1 jruoho Found in tools/acpisrc/* 14609 1.1 jruoho 14610 1.1 jruoho OsdUnMapMemory was renamed to OsdUnmapMemory and then 14611 1.1 jruoho AcpiOsUnmapMemory. (UnMap became Unmap). 14612 1.1 jruoho 14613 1.1 jruoho A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore. 14614 1.1 jruoho When set to one, this indicates that the caller wants to use the 14615 1.1 jruoho 14616 1.1 jruoho semaphore as a mutex, not a counting semaphore. ACPI CA uses 14617 1.1 jruoho both types. However, implementers of this call may want to use 14618 1.1 jruoho different OS primitives depending on the type of semaphore 14619 1.1 jruoho requested. For example, some operating systems provide separate 14620 1.1 jruoho 14621 1.1 jruoho "mutex" and "semaphore" interfaces - where the mutex interface is 14622 1.1 jruoho much faster because it doesn't have all the overhead of a full 14623 1.1 jruoho semaphore implementation. 14624 1.1 jruoho 14625 1.1 jruoho Fixed a deadlock problem where a method that accesses the PCI 14626 1.1 jruoho address space can block forever if it is the first access to the 14627 1.1 jruoho space. 14628 1.1 jruoho 14629 1.1 jruoho ------------------------------------------- 14630 1.1 jruoho Summary of changes for this label: 06_02_00 14631 1.1 jruoho 14632 1.1 jruoho Support for environments that cannot handle unaligned data 14633 1.1 jruoho accesses (e.g. firmware and OS environments devoid of alignment 14634 1.1 jruoho handler technology namely SAL/EFI and the IA-64 Linux kernel) has 14635 1.1 jruoho been added (via configurable macros) in these three areas: - 14636 1.1 jruoho Transfer of data from the raw AML byte stream is done via byte 14637 1.1 jruoho moves instead of word/dword/qword moves. - External objects are 14638 1.1 jruoho aligned within the user buffer, including package elements (sub- 14639 1.1 jruoho objects). - Conversion of name strings to UINT32 Acpi Names is now 14640 1.1 jruoho done byte-wise. 14641 1.1 jruoho 14642 1.1 jruoho The Store operator was modified to mimic Microsoft's 14643 1.1 jruoho implementation when storing to a Buffer Field. 14644 1.1 jruoho 14645 1.1 jruoho Added a check of the BM_STS bit before entering C3. 14646 1.1 jruoho 14647 1.1 jruoho The methods subdirectory has been obsoleted and removed. A new 14648 1.1 jruoho file, cmeval.c subsumes the functionality. 14649 1.1 jruoho 14650 1.1 jruoho A 16-bit (DOS) version of AcpiExec has been developed. The 14651 1.1 jruoho makefile is under the acpiexec directory. 14652
