1 1.1 jruoho ---------------------------------------- 2 1.1.1.2 jruoho 11 February 2011. Summary of changes for version 20110211: 3 1.1 jruoho 4 1.1 jruoho This release is available at www.acpica.org/downloads 5 1.1 jruoho 6 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 7 1.1.1.2 jruoho 8 1.1.1.2 jruoho Added a mechanism to defer _REG methods for some early-installed handlers. 9 1.1.1.2 jruoho Most user handlers should be installed before call to AcpiEnableSubsystem. 10 1.1.1.2 jruoho However, Event handlers and region handlers should be installed after 11 1.1.1.2 jruoho AcpiInitializeObjects. Override handlers for the "default" regions should be 12 1.1.1.2 jruoho installed early, however. This change executes all _REG methods for the 13 1.1.1.2 jruoho default regions (Memory/IO/PCI/DataTable) simultaneously to prevent any 14 1.1.1.2 jruoho chicken/egg issues between them. ACPICA BZ 848. 15 1.1.1.2 jruoho 16 1.1.1.2 jruoho Implemented an optimization for GPE detection. This optimization will simply 17 1.1.1.2 jruoho ignore GPE registers that contain no enabled GPEs -- there is no need to 18 1.1.1.2 jruoho read the register since this information is available internally. This 19 1.1.1.2 jruoho becomes more important on machines with a large GPE space. ACPICA bugzilla 20 1.1.1.2 jruoho 884. Lin Ming. Suggestion from Joe Liu. 21 1.1.1.2 jruoho 22 1.1.1.2 jruoho Removed all use of the highly unreliable FADT revision field. The revision 23 1.1.1.2 jruoho number in the FADT has been found to be completely unreliable and cannot be 24 1.1.1.2 jruoho trusted. Only the actual table length can be used to infer the version. This 25 1.1.1.2 jruoho change updates the ACPICA core and the disassembler so that both no longer 26 1.1.1.2 jruoho even look at the FADT version and instead depend solely upon the FADT 27 1.1.1.2 jruoho length. 28 1.1.1.2 jruoho 29 1.1.1.2 jruoho Fix an unresolved name issue for the no-debug and no-error-message source 30 1.1.1.2 jruoho generation cases. The _AcpiModuleName was left undefined in these cases, but 31 1.1.1.2 jruoho it is actually needed as a parameter to some interfaces. Define 32 1.1.1.2 jruoho _AcpiModuleName as a null string in these cases. ACPICA Bugzilla 888. 33 1.1.1.2 jruoho 34 1.1.1.2 jruoho Split several large files (makefiles and project files updated) 35 1.1.1.2 jruoho utglobal.c -> utdecode.c 36 1.1.1.2 jruoho dbcomds.c -> dbmethod.c dbnames.c 37 1.1.1.2 jruoho dsopcode.c -> dsargs.c dscontrol.c 38 1.1.1.2 jruoho dsload.c -> dsload2.c 39 1.1.1.2 jruoho aslanalyze.c -> aslbtypes.c aslwalks.c 40 1.1.1.2 jruoho 41 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 42 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 43 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 44 1.1.1.2 jruoho a much larger code and data size. 45 1.1.1.2 jruoho 46 1.1.1.2 jruoho Previous Release (VC 9.0): 47 1.1.1.2 jruoho Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 48 1.1.1.2 jruoho Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 49 1.1.1.2 jruoho Current Release (VC 9.0): 50 1.1.1.2 jruoho Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 51 1.1.1.2 jruoho Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 52 1.1.1.2 jruoho 53 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 54 1.1.1.2 jruoho 55 1.1.1.2 jruoho iASL: Implemented the predefined macros __LINE__, __FILE__, and __DATE__. 56 1.1.1.2 jruoho These are useful C-style macros with the standard definitions. ACPICA 57 1.1.1.2 jruoho bugzilla 898. 58 1.1.1.2 jruoho 59 1.1.1.2 jruoho iASL/DTC: Added support for integer expressions and labels. Support for full 60 1.1.1.2 jruoho expressions for all integer fields in all ACPI tables. Support for labels in 61 1.1.1.2 jruoho "generic" portions of tables such as UEFI. See the iASL reference manual. 62 1.1.1.2 jruoho 63 1.1.1.2 jruoho Debugger: Added a command to display the status of global handlers. The 64 1.1.1.2 jruoho "handlers" command will display op region, fixed event, and miscellaneous 65 1.1.1.2 jruoho global handlers. installation status -- and for op regions, whether default 66 1.1.1.2 jruoho or user-installed handler will be used. 67 1.1.1.2 jruoho 68 1.1.1.2 jruoho iASL: Warn if reserved method incorrectly returns a value. Many predefined 69 1.1.1.2 jruoho names are defined such that they do not return a value. If implemented as a 70 1.1.1.2 jruoho method, issue a warning if such a name explicitly returns a value. ACPICA 71 1.1.1.2 jruoho Bugzilla 855. 72 1.1.1.2 jruoho 73 1.1.1.2 jruoho iASL: Added detection of GPE method name conflicts. Detects a conflict where 74 1.1.1.2 jruoho there are two GPE methods of the form _Lxy and _Exy in the same scope. (For 75 1.1.1.2 jruoho example, _L1D and _E1D in the same scope.) ACPICA bugzilla 848. 76 1.1.1.2 jruoho 77 1.1.1.2 jruoho iASL/DTC: Fixed a couple input scanner issues with comments and line 78 1.1.1.2 jruoho numbers. Comment remover could get confused and miss a comment ending. Fixed 79 1.1.1.2 jruoho a problem with line counter maintenance. 80 1.1.1.2 jruoho 81 1.1.1.2 jruoho iASL/DTC: Reduced the severity of some errors from fatal to error. There is 82 1.1.1.2 jruoho no need to abort on simple errors within a field definition. 83 1.1.1.2 jruoho 84 1.1.1.2 jruoho Debugger: Simplified the output of the help command. All help output now in 85 1.1.1.2 jruoho a single screen, instead of help subcommands. ACPICA Bugzilla 897. 86 1.1.1.2 jruoho 87 1.1.1.2 jruoho 88 1.1.1.2 jruoho ---------------------------------------- 89 1.1.1.2 jruoho 12 January 2011. Summary of changes for version 20110112: 90 1.1.1.2 jruoho 91 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 92 1.1.1.2 jruoho 93 1.1.1.2 jruoho Fixed a race condition between method execution and namespace walks that can 94 1.1.1.2 jruoho possibly cause a fault. The problem was apparently introduced in version 95 1.1.1.2 jruoho 20100528 as a result of a performance optimization that reduces the number 96 1.1.1.2 jruoho of 97 1.1.1.2 jruoho namespace walks upon method exit by using the delete_namespace_subtree 98 1.1.1.2 jruoho function instead of the delete_namespace_by_owner function used previously. 99 1.1.1.2 jruoho Bug is a missing namespace lock in the delete_namespace_subtree function. 100 1.1.1.2 jruoho dana.myers (a] oracle.com 101 1.1.1.2 jruoho 102 1.1.1.2 jruoho Fixed several issues and a possible fault with the automatic "serialized" 103 1.1.1.2 jruoho method support. History: This support changes a method to "serialized" on 104 1.1.1.2 jruoho the 105 1.1.1.2 jruoho fly if the method generates an AE_ALREADY_EXISTS error, indicating the 106 1.1.1.2 jruoho possibility that it cannot handle reentrancy. This fix repairs a couple of 107 1.1.1.2 jruoho issues seen in the field, especially on machines with many cores: 108 1.1.1.2 jruoho 109 1.1.1.2 jruoho 1) Delete method children only upon the exit of the last thread, 110 1.1.1.2 jruoho so as to not delete objects out from under other running threads 111 1.1.1.2 jruoho (and possibly causing a fault.) 112 1.1.1.2 jruoho 2) Set the "serialized" bit for the method only upon the exit of the 113 1.1.1.2 jruoho Last thread, so as to not cause deadlock when running threads 114 1.1.1.2 jruoho attempt to exit. 115 1.1.1.2 jruoho 3) Cleanup the use of the AML "MethodFlags" and internal method flags 116 1.1.1.2 jruoho so that there is no longer any confusion between the two. 117 1.1.1.2 jruoho 118 1.1.1.2 jruoho Lin Ming, Bob Moore. Reported by dana.myers (a] oracle.com. 119 1.1.1.2 jruoho 120 1.1.1.2 jruoho Debugger: Now lock the namespace for duration of a namespace dump. Prevents 121 1.1.1.2 jruoho issues if the namespace is changing dynamically underneath the debugger. 122 1.1.1.2 jruoho Especially affects temporary namespace nodes, since the debugger displays 123 1.1.1.2 jruoho these also. 124 1.1.1.2 jruoho 125 1.1.1.2 jruoho Updated the ordering of include files. The ACPICA headers should appear 126 1.1.1.2 jruoho before any compiler-specific headers (stdio.h, etc.) so that acenv.h can set 127 1.1.1.2 jruoho any necessary compiler-specific defines, etc. Affects the ACPI-related tools 128 1.1.1.2 jruoho and utilities. 129 1.1.1.2 jruoho 130 1.1.1.2 jruoho Updated all ACPICA copyrights and signons to 2011. Added the 2011 copyright 131 1.1.1.2 jruoho to all module headers and signons, including the Linux header. This affects 132 1.1.1.2 jruoho virtually every file in the ACPICA core subsystem, iASL compiler, and all 133 1.1.1.2 jruoho utilities. 134 1.1.1.2 jruoho 135 1.1.1.2 jruoho Added project files for MS Visual Studio 2008 (VC++ 9.0). The original 136 1.1.1.2 jruoho project files for VC++ 6.0 are now obsolete. New project files can be found 137 1.1.1.2 jruoho under acpica/generate/msvc9. See acpica/generate/msvc9/readme.txt for 138 1.1.1.2 jruoho details. 139 1.1.1.2 jruoho 140 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 141 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 142 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 143 1.1.1.2 jruoho a 144 1.1.1.2 jruoho much larger code and data size. 145 1.1.1.2 jruoho 146 1.1.1.2 jruoho Previous Release (VC 6.0): 147 1.1.1.2 jruoho Non-Debug Version: 89.8K Code, 18.9K Data, 108.7K Total 148 1.1.1.2 jruoho Debug Version: 166.6K Code, 52.1K Data, 218.7K Total 149 1.1.1.2 jruoho Current Release (VC 9.0): 150 1.1.1.2 jruoho Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 151 1.1.1.2 jruoho Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 152 1.1.1.2 jruoho 153 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 154 1.1.1.2 jruoho 155 1.1.1.2 jruoho iASL: Added generic data types to the Data Table compiler. Add "generic" 156 1.1.1.2 jruoho data 157 1.1.1.2 jruoho types such as UINT32, String, Unicode, etc., to simplify the generation of 158 1.1.1.2 jruoho platform-defined tables such as UEFI. Lin Ming. 159 1.1.1.2 jruoho 160 1.1.1.2 jruoho iASL: Added listing support for the Data Table Compiler. Adds listing 161 1.1.1.2 jruoho support 162 1.1.1.2 jruoho (-l) to display actual binary output for each line of input code. 163 1.1.1.2 jruoho 164 1.1.1.2 jruoho ---------------------------------------- 165 1.1.1.2 jruoho 09 December 2010. Summary of changes for version 20101209: 166 1.1.1.2 jruoho 167 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 168 1.1.1.2 jruoho 169 1.1.1.2 jruoho Completed the major overhaul of the GPE support code that was begun in July 170 1.1.1.2 jruoho 2010. Major features include: removal of _PRW execution in ACPICA (host 171 1.1.1.2 jruoho executes _PRWs anyway), cleanup of "wake" GPE interfaces and processing, 172 1.1.1.2 jruoho changes to existing interfaces, simplification of GPE handler operation, and 173 1.1.1.2 jruoho a handful of new interfaces: 174 1.1.1.2 jruoho 175 1.1.1.2 jruoho AcpiUpdateAllGpes 176 1.1.1.2 jruoho AcpiFinishGpe 177 1.1.1.2 jruoho AcpiSetupGpeForWake 178 1.1.1.2 jruoho AcpiSetGpeWakeMask 179 1.1.1.2 jruoho One new file, evxfgpe.c to consolidate all external GPE interfaces. 180 1.1.1.2 jruoho 181 1.1.1.2 jruoho See the ACPICA Programmer Reference for full details and programming 182 1.1.1.2 jruoho information. See the new section 4.4 "General Purpose Event (GPE) Support" 183 1.1.1.2 jruoho for a full overview, and section 8.7 "ACPI General Purpose Event Management" 184 1.1.1.2 jruoho for programming details. ACPICA BZ 858,870,877. Matthew Garrett, Lin Ming, 185 1.1.1.2 jruoho Bob Moore, Rafael Wysocki. 186 1.1.1.2 jruoho 187 1.1.1.2 jruoho Implemented a new GPE feature for Windows compatibility, the "Implicit Wake 188 1.1.1.2 jruoho GPE Notify". This feature will automatically issue a Notify(2) on a device 189 1.1.1.2 jruoho when a Wake GPE is received if there is no corresponding GPE method or 190 1.1.1.2 jruoho handler. ACPICA BZ 870. 191 1.1.1.2 jruoho 192 1.1.1.2 jruoho Fixed a problem with the Scope() operator during table parse and load phase. 193 1.1.1.2 jruoho During load phase (table load or method execution), the scope operator 194 1.1.1.2 jruoho should 195 1.1.1.2 jruoho not enter the target into the namespace. Instead, it should open a new scope 196 1.1.1.2 jruoho at the target location. Linux BZ 19462, ACPICA BZ 882. 197 1.1.1.2 jruoho 198 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 199 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 200 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 201 1.1.1.2 jruoho a 202 1.1.1.2 jruoho much larger code and data size. 203 1.1.1.2 jruoho 204 1.1.1.2 jruoho Previous Release: 205 1.1.1.2 jruoho Non-Debug Version: 89.8K Code, 18.9K Data, 108.7K Total 206 1.1.1.2 jruoho Debug Version: 166.6K Code, 52.1K Data, 218.7K Total 207 1.1.1.2 jruoho Current Release: 208 1.1.1.2 jruoho Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 209 1.1.1.2 jruoho Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 210 1.1.1.2 jruoho 211 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 212 1.1.1.2 jruoho 213 1.1.1.2 jruoho iASL: Relax the alphanumeric restriction on _CID strings. These strings are 214 1.1.1.2 jruoho "bus-specific" per the ACPI specification, and therefore any characters are 215 1.1.1.2 jruoho acceptable. The only checks that can be performed are for a null string and 216 1.1.1.2 jruoho perhaps for a leading asterisk. ACPICA BZ 886. 217 1.1.1.2 jruoho 218 1.1.1.2 jruoho iASL: Fixed a problem where a syntax error that caused a premature EOF 219 1.1.1.2 jruoho condition on the source file emitted a very confusing error message. The 220 1.1.1.2 jruoho premature EOF is now detected correctly. ACPICA BZ 891. 221 1.1.1.2 jruoho 222 1.1.1.2 jruoho Disassembler: Decode the AccessSize within a Generic Address Structure (byte 223 1.1.1.2 jruoho access, word access, etc.) Note, this field does not allow arbitrary bit 224 1.1.1.2 jruoho access, the size is encoded as 1=byte, 2=word, 3=dword, and 4=qword. 225 1.1.1.2 jruoho 226 1.1.1.2 jruoho New: AcpiNames utility - Example namespace dump utility. Shows an example of 227 1.1.1.2 jruoho ACPICA configuration for a minimal namespace dump utility. Uses table and 228 1.1.1.2 jruoho namespace managers, but no AML interpreter. Does not add any functionality 229 1.1.1.2 jruoho over AcpiExec, it is a subset of AcpiExec. The purpose is to show how to 230 1.1.1.2 jruoho partition and configure ACPICA. ACPICA BZ 883. 231 1.1.1.2 jruoho 232 1.1.1.2 jruoho AML Debugger: Increased the debugger buffer size for method return objects. 233 1.1.1.2 jruoho Was 4K, increased to 16K. Also enhanced error messages for debugger method 234 1.1.1.2 jruoho execution, including the buffer overflow case. 235 1.1.1.2 jruoho 236 1.1.1.2 jruoho ---------------------------------------- 237 1.1.1.2 jruoho 13 October 2010. Summary of changes for version 20101013: 238 1.1.1.2 jruoho 239 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 240 1.1.1.2 jruoho 241 1.1.1.2 jruoho Added support to clear the PCIEXP_WAKE event. When clearing ACPI events, now 242 1.1.1.2 jruoho clear the PCIEXP_WAKE_STS bit in the ACPI PM1 Status Register, via 243 1.1.1.2 jruoho HwClearAcpiStatus. Original change from Colin King. ACPICA BZ 880. 244 1.1.1.2 jruoho 245 1.1.1.2 jruoho Changed the type of the predefined namespace object _TZ from ThermalZone to 246 1.1.1.2 jruoho Device. This was found to be confusing to the host software that processes 247 1.1.1.2 jruoho the various thermal zones, since _TZ is not really a ThermalZone. However, a 248 1.1.1.2 jruoho Notify() can still be performed on it. ACPICA BZ 876. Suggestion from Rui 249 1.1.1.2 jruoho Zhang. 250 1.1.1.2 jruoho 251 1.1.1.2 jruoho Added Windows Vista SP2 to the list of supported _OSI strings. The actual 252 1.1.1.2 jruoho string is "Windows 2006 SP2". 253 1.1.1.2 jruoho 254 1.1.1.2 jruoho Eliminated duplicate code in AcpiUtExecute* functions. Now that the nsrepair 255 1.1.1.2 jruoho code automatically repairs _HID-related strings, this type of code is no 256 1.1.1.2 jruoho longer needed in Execute_HID, Execute_CID, and Execute_UID. ACPICA BZ 878. 257 1.1.1.2 jruoho 258 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 259 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 260 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 261 1.1.1.2 jruoho a 262 1.1.1.2 jruoho much larger code and data size. 263 1.1.1.2 jruoho 264 1.1.1.2 jruoho Previous Release: 265 1.1.1.2 jruoho Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 266 1.1.1.2 jruoho Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 267 1.1.1.2 jruoho Current Release: 268 1.1.1.2 jruoho Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 269 1.1.1.2 jruoho Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 270 1.1.1.2 jruoho 271 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 272 1.1.1.2 jruoho 273 1.1.1.2 jruoho iASL: Implemented additional compile-time validation for _HID strings. The 274 1.1.1.2 jruoho non-hex prefix (such as "PNP" or "ACPI") must be uppercase, and the length 275 1.1.1.2 jruoho of 276 1.1.1.2 jruoho the string must be exactly seven or eight characters. For both _HID and _CID 277 1.1.1.2 jruoho strings, all characters must be alphanumeric. ACPICA BZ 874. 278 1.1.1.2 jruoho 279 1.1.1.2 jruoho iASL: Allow certain "null" resource descriptors. Some BIOS code creates 280 1.1.1.2 jruoho descriptors that are mostly or all zeros, with the expectation that they 281 1.1.1.2 jruoho will 282 1.1.1.2 jruoho be filled in at runtime. iASL now allows this as long as there is a 283 1.1.1.2 jruoho "resource 284 1.1.1.2 jruoho tag" (name) associated with the descriptor, which gives the ASL a handle 285 1.1.1.2 jruoho needed to modify the descriptor. ACPICA BZ 873. 286 1.1.1.2 jruoho 287 1.1.1.2 jruoho Added single-thread support to the generic Unix application OSL. Primarily 288 1.1.1.2 jruoho for iASL support, this change removes the use of semaphores in the single- 289 1.1.1.2 jruoho threaded ACPICA tools/applications - increasing performance. The 290 1.1.1.2 jruoho _MULTI_THREADED option was replaced by the (reverse) ACPI_SINGLE_THREADED 291 1.1.1.2 jruoho option. ACPICA BZ 879. 292 1.1.1.2 jruoho 293 1.1.1.2 jruoho AcpiExec: several fixes for the 64-bit version. Adds XSDT support and 294 1.1.1.2 jruoho support 295 1.1.1.2 jruoho for 64-bit DSDT/FACS addresses in the FADT. Lin Ming. 296 1.1.1.2 jruoho 297 1.1.1.2 jruoho iASL: Moved all compiler messages to a new file, aslmessages.h. 298 1.1.1.2 jruoho 299 1.1.1.2 jruoho ---------------------------------------- 300 1.1.1.2 jruoho 15 September 2010. Summary of changes for version 20100915: 301 1.1.1.2 jruoho 302 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 303 1.1.1.2 jruoho 304 1.1.1.2 jruoho Removed the AcpiOsDerivePciId OSL interface. The various host 305 1.1.1.2 jruoho implementations 306 1.1.1.2 jruoho of this function were not OS-dependent and are now obsolete and can be 307 1.1.1.2 jruoho removed from all host OSLs. This function has been replaced by 308 1.1.1.2 jruoho AcpiHwDerivePciId, which is now part of the ACPICA core code. 309 1.1.1.2 jruoho AcpiHwDerivePciId has been implemented without recursion. Adds one new 310 1.1.1.2 jruoho module, hwpci.c. ACPICA BZ 857. 311 1.1.1.2 jruoho 312 1.1.1.2 jruoho Implemented a dynamic repair for _HID and _CID strings. The following 313 1.1.1.2 jruoho problems are now repaired at runtime: 1) Remove a leading asterisk in the 314 1.1.1.2 jruoho string, and 2) the entire string is uppercased. Both repairs are in 315 1.1.1.2 jruoho accordance with the ACPI specification and will simplify host driver code. 316 1.1.1.2 jruoho ACPICA BZ 871. 317 1.1.1.2 jruoho 318 1.1.1.2 jruoho The ACPI_THREAD_ID type is no longer configurable, internally it is now 319 1.1.1.2 jruoho always UINT64. This simplifies the ACPICA code, especially any printf 320 1.1.1.2 jruoho output. 321 1.1.1.2 jruoho UINT64 is the only common data type for all thread_id types across all 322 1.1.1.2 jruoho operating systems. It is now up to the host OSL to cast the native thread_id 323 1.1.1.2 jruoho type to UINT64 before returning the value to ACPICA (via AcpiOsGetThreadId). 324 1.1.1.2 jruoho Lin Ming, Bob Moore. 325 1.1.1.2 jruoho 326 1.1.1.2 jruoho Added the ACPI_INLINE type to enhance the ACPICA configuration. The "inline" 327 1.1.1.2 jruoho keyword is not standard across compilers, and this type allows inline to be 328 1.1.1.2 jruoho configured on a per-compiler basis. Lin Ming. 329 1.1.1.2 jruoho 330 1.1.1.2 jruoho Made the system global AcpiGbl_SystemAwakeAndRunning publically available. 331 1.1.1.2 jruoho Added an extern for this boolean in acpixf.h. Some hosts utilize this value 332 1.1.1.2 jruoho during suspend/restore operations. ACPICA BZ 869. 333 1.1.1.2 jruoho 334 1.1.1.2 jruoho All code that implements error/warning messages with the "ACPI:" prefix has 335 1.1.1.2 jruoho been moved to a new module, utxferror.c. 336 1.1.1.2 jruoho 337 1.1.1.2 jruoho The UINT64_OVERLAY was moved to utmath.c, which is the only module where it 338 1.1.1.2 jruoho is used. ACPICA BZ 829. Lin Ming, Bob Moore. 339 1.1.1.2 jruoho 340 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 341 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 342 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 343 1.1.1.2 jruoho a 344 1.1.1.2 jruoho much larger code and data size. 345 1.1.1.2 jruoho 346 1.1.1.2 jruoho Previous Release: 347 1.1.1.2 jruoho Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 348 1.1.1.2 jruoho Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 349 1.1.1.2 jruoho Current Release: 350 1.1.1.2 jruoho Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 351 1.1.1.2 jruoho Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 352 1.1.1.2 jruoho 353 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 354 1.1.1.2 jruoho 355 1.1.1.2 jruoho iASL/Disassembler: Write ACPI errors to stderr instead of the output file. 356 1.1.1.2 jruoho This keeps the output files free of random error messages that may originate 357 1.1.1.2 jruoho from within the namespace/interpreter code. Used this opportunity to merge 358 1.1.1.2 jruoho all ACPI:-style messages into a single new module, utxferror.c. ACPICA BZ 359 1.1.1.2 jruoho 866. Lin Ming, Bob Moore. 360 1.1.1.2 jruoho 361 1.1.1.2 jruoho Tools: update some printfs for ansi warnings on size_t. Handle width change 362 1.1.1.2 jruoho of size_t on 32-bit versus 64-bit generations. Lin Ming. 363 1.1.1.2 jruoho 364 1.1.1.2 jruoho ---------------------------------------- 365 1.1.1.2 jruoho 06 August 2010. Summary of changes for version 20100806: 366 1.1.1.2 jruoho 367 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 368 1.1.1.2 jruoho 369 1.1.1.2 jruoho Designed and implemented a new host interface to the _OSI support code. This 370 1.1.1.2 jruoho will allow the host to dynamically add or remove multiple _OSI strings, as 371 1.1.1.2 jruoho well as install an optional handler that is called for each _OSI invocation. 372 1.1.1.2 jruoho Also added a new AML debugger command, 'osi' to display and modify the 373 1.1.1.2 jruoho global 374 1.1.1.2 jruoho _OSI string table, and test support in the AcpiExec utility. See the ACPICA 375 1.1.1.2 jruoho reference manual for full details. Lin Ming, Bob Moore. ACPICA BZ 836. 376 1.1.1.2 jruoho New Functions: 377 1.1.1.2 jruoho AcpiInstallInterface - Add an _OSI string. 378 1.1.1.2 jruoho AcpiRemoveInterface - Delete an _OSI string. 379 1.1.1.2 jruoho AcpiInstallInterfaceHandler - Install optional _OSI handler. 380 1.1.1.2 jruoho Obsolete Functions: 381 1.1.1.2 jruoho AcpiOsValidateInterface - no longer used. 382 1.1.1.2 jruoho New Files: 383 1.1.1.2 jruoho source/components/utilities/utosi.c 384 1.1.1.2 jruoho 385 1.1.1.2 jruoho Re-introduced the support to enable multi-byte transfers for Embedded 386 1.1.1.2 jruoho Controller (EC) operation regions. A reported problem was found to be a bug 387 1.1.1.2 jruoho in the host OS, not in the multi-byte support. Previously, the maximum data 388 1.1.1.2 jruoho size passed to the EC operation region handler was a single byte. There are 389 1.1.1.2 jruoho often EC Fields larger than one byte that need to be transferred, and it is 390 1.1.1.2 jruoho useful for the EC driver to lock these as a single transaction. This change 391 1.1.1.2 jruoho enables single transfers larger than 8 bits. This effectively changes the 392 1.1.1.2 jruoho access to the EC space from ByteAcc to AnyAcc, and will probably require 393 1.1.1.2 jruoho changes to the host OS Embedded Controller driver to enable 16/32/64/256-bit 394 1.1.1.2 jruoho transfers in addition to 8-bit transfers. Alexey Starikovskiy, Lin Ming. 395 1.1.1.2 jruoho 396 1.1.1.2 jruoho Fixed a problem with the prototype for AcpiOsReadPciConfiguration. The 397 1.1.1.2 jruoho prototype in acpiosxf.h had the output value pointer as a (void *). 398 1.1.1.2 jruoho It should be a (UINT64 *). This may affect some host OSL code. 399 1.1.1.2 jruoho 400 1.1.1.2 jruoho Fixed a couple problems with the recently modified Linux makefiles for iASL 401 1.1.1.2 jruoho and AcpiExec. These new makefiles place the generated object files in the 402 1.1.1.2 jruoho local directory so that there can be no collisions between the files that 403 1.1.1.2 jruoho are 404 1.1.1.2 jruoho shared between them that are compiled with different options. 405 1.1.1.2 jruoho 406 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 407 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 408 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 409 1.1.1.2 jruoho a 410 1.1.1.2 jruoho much larger code and data size. 411 1.1.1.2 jruoho 412 1.1.1.2 jruoho Previous Release: 413 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 414 1.1.1.2 jruoho Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 415 1.1.1.2 jruoho Current Release: 416 1.1.1.2 jruoho Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 417 1.1.1.2 jruoho Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 418 1.1.1.2 jruoho 419 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 420 1.1.1.2 jruoho 421 1.1.1.2 jruoho iASL/Disassembler: Added a new option (-da, "disassemble all") to load the 422 1.1.1.2 jruoho namespace from and disassemble an entire group of AML files. Useful for 423 1.1.1.2 jruoho loading all of the AML tables for a given machine (DSDT, SSDT1...SSDTn) and 424 1.1.1.2 jruoho disassembling with one simple command. ACPICA BZ 865. Lin Ming. 425 1.1.1.2 jruoho 426 1.1.1.2 jruoho iASL: Allow multiple invocations of -e option. This change allows multiple 427 1.1.1.2 jruoho uses of -e on the command line: "-e ssdt1.dat -e ssdt2.dat". ACPICA BZ 834. 428 1.1.1.2 jruoho Lin Ming. 429 1.1.1.2 jruoho 430 1.1.1.2 jruoho ---------------------------------------- 431 1.1.1.2 jruoho 02 July 2010. Summary of changes for version 20100702: 432 1.1.1.2 jruoho 433 1.1.1.2 jruoho 1) ACPI CA Core Subsystem: 434 1.1.1.2 jruoho 435 1.1.1.2 jruoho Implemented several updates to the recently added GPE reference count 436 1.1.1.2 jruoho support. The model for "wake" GPEs is changing to give the host OS complete 437 1.1.1.2 jruoho control of these GPEs. Eventually, the ACPICA core will not execute any _PRW 438 1.1.1.2 jruoho methods, since the host already must execute them. Also, additional changes 439 1.1.1.2 jruoho were made to help ensure that the reference counts are kept in proper 440 1.1.1.2 jruoho synchronization with reality. Rafael J. Wysocki. 441 1.1.1.2 jruoho 442 1.1.1.2 jruoho 1) Ensure that GPEs are not enabled twice during initialization. 443 1.1.1.2 jruoho 2) Ensure that GPE enable masks stay in sync with the reference count. 444 1.1.1.2 jruoho 3) Do not inadvertently enable GPEs when writing GPE registers. 445 1.1.1.2 jruoho 4) Remove the internal wake reference counter and add new AcpiGpeWakeup 446 1.1.1.2 jruoho interface. This interface will set or clear individual GPEs for wakeup. 447 1.1.1.2 jruoho 5) Remove GpeType argument from AcpiEnable and AcpiDisable. These interfaces 448 1.1.1.2 jruoho are now used for "runtime" GPEs only. 449 1.1.1.2 jruoho 450 1.1.1.2 jruoho Changed the behavior of the GPE install/remove handler interfaces. The GPE 451 1.1.1.2 jruoho is 452 1.1.1.2 jruoho no longer disabled during this process, as it was found to cause problems on 453 1.1.1.2 jruoho some machines. Rafael J. Wysocki. 454 1.1.1.2 jruoho 455 1.1.1.2 jruoho Reverted a change introduced in version 20100528 to enable Embedded 456 1.1.1.2 jruoho Controller multi-byte transfers. This change was found to cause problems 457 1.1.1.2 jruoho with 458 1.1.1.2 jruoho Index Fields and possibly Bank Fields. It will be reintroduced when these 459 1.1.1.2 jruoho problems have been resolved. 460 1.1.1.2 jruoho 461 1.1.1.2 jruoho Fixed a problem with references to Alias objects within Package Objects. A 462 1.1.1.2 jruoho reference to an Alias within the definition of a Package was not always 463 1.1.1.2 jruoho resolved properly. Aliases to objects like Processors, Thermal zones, etc. 464 1.1.1.2 jruoho were resolved to the actual object instead of a reference to the object as 465 1.1.1.2 jruoho it 466 1.1.1.2 jruoho should be. Package objects are only allowed to contain integer, string, 467 1.1.1.2 jruoho buffer, package, and reference objects. Redhat bugzilla 608648. 468 1.1.1.2 jruoho 469 1.1.1.2 jruoho Example Code and Data Size: These are the sizes for the OS-independent 470 1.1.1.2 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 471 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 472 1.1.1.2 jruoho a 473 1.1.1.2 jruoho much larger code and data size. 474 1.1.1.2 jruoho 475 1.1.1.2 jruoho Previous Release: 476 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 477 1.1.1.2 jruoho Debug Version: 164.1K Code, 51.5K Data, 215.6K Total 478 1.1.1.2 jruoho Current Release: 479 1.1.1.2 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 480 1.1.1.2 jruoho Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 481 1.1.1.2 jruoho 482 1.1.1.2 jruoho 2) iASL Compiler/Disassembler and Tools: 483 1.1.1.2 jruoho 484 1.1.1.2 jruoho iASL: Implemented a new compiler subsystem to allow definition and 485 1.1.1.2 jruoho compilation of the non-AML ACPI tables such as FADT, MADT, SRAT, etc. These 486 1.1.1.2 jruoho are called "ACPI Data Tables", and the new compiler is the "Data Table 487 1.1.1.2 jruoho Compiler". This compiler is intended to simplify the existing error-prone 488 1.1.1.2 jruoho process of creating these tables for the BIOS, as well as allowing the 489 1.1.1.2 jruoho disassembly, modification, recompilation, and override of existing ACPI data 490 1.1.1.2 jruoho tables. See the iASL User Guide for detailed information. 491 1.1.1.2 jruoho 492 1.1.1.2 jruoho iASL: Implemented a new Template Generator option in support of the new Data 493 1.1.1.2 jruoho Table Compiler. This option will create examples of all known ACPI tables 494 1.1.1.2 jruoho that can be used as the basis for table development. See the iASL 495 1.1.1.2 jruoho documentation and the -T option. 496 1.1.1.2 jruoho 497 1.1.1.2 jruoho Disassembler and headers: Added support for the WDDT ACPI table (Watchdog 498 1.1.1.2 jruoho Descriptor Table). 499 1.1.1.2 jruoho 500 1.1.1.2 jruoho Updated the Linux makefiles for iASL and AcpiExec to place the generated 501 1.1.1.2 jruoho object files in the local directory so that there can be no collisions 502 1.1.1.2 jruoho between the shared files between them that are generated with different 503 1.1.1.2 jruoho options. 504 1.1.1.2 jruoho 505 1.1.1.2 jruoho Added support for Mac OS X in the Unix OSL used for iASL and AcpiExec. Use 506 1.1.1.2 jruoho the #define __APPLE__ to enable this support. 507 1.1.1.2 jruoho 508 1.1.1.2 jruoho ---------------------------------------- 509 1.1.1.2 jruoho 28 May 2010. Summary of changes for version 20100528: 510 1.1.1.2 jruoho 511 1.1 jruoho Note: The ACPI 4.0a specification was released on April 5, 2010 and is 512 1.1 jruoho available at www.acpi.info. This is primarily an errata release. 513 1.1 jruoho 514 1.1 jruoho 1) ACPI CA Core Subsystem: 515 1.1 jruoho 516 1.1 jruoho Undefined ACPI tables: We are looking for the definitions for the following 517 1.1 jruoho ACPI tables that have been seen in the field: ATKG, IEIT, GSCI. 518 1.1 jruoho 519 1.1 jruoho Implemented support to enable multi-byte transfers for Embedded Controller 520 1.1 jruoho (EC) operation regions. Previously, the maximum data size passed to the EC 521 1.1 jruoho operation region handler was a single byte. There are often EC Fields larger 522 1.1.1.2 jruoho than one byte that need to be transferred, and it is useful for the EC 523 1.1.1.2 jruoho driver 524 1.1 jruoho to lock these as a single transaction. This change enables single transfers 525 1.1 jruoho larger than 8 bits. This effectively changes the access to the EC space from 526 1.1 jruoho ByteAcc to AnyAcc, and will probably require changes to the host OS Embedded 527 1.1 jruoho Controller driver to enable 16/32/64/256-bit transfers in addition to 8-bit 528 1.1 jruoho transfers. Alexey Starikovskiy, Lin Ming 529 1.1 jruoho 530 1.1 jruoho Implemented a performance enhancement for namespace search and access. This 531 1.1 jruoho change enhances the performance of namespace searches and walks by adding a 532 1.1 jruoho backpointer to the parent in each namespace node. On large namespaces, this 533 1.1 jruoho change can improve overall ACPI performance by up to 9X. Adding a pointer to 534 1.1 jruoho each namespace node increases the overall size of the internal namespace by 535 1.1 jruoho about 5%, since each namespace entry usually consists of both a namespace 536 1.1 jruoho node and an ACPI operand object. However, this is the first growth of the 537 1.1 jruoho namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy. 538 1.1 jruoho 539 1.1 jruoho Implemented a performance optimization that reduces the number of namespace 540 1.1.1.2 jruoho walks. On control method exit, only walk the namespace if the method is 541 1.1.1.2 jruoho known 542 1.1.1.2 jruoho to have created namespace objects outside of its local scope. Previously, 543 1.1.1.2 jruoho the 544 1.1 jruoho entire namespace was traversed on each control method exit. This change can 545 1.1.1.2 jruoho improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob 546 1.1.1.2 jruoho Moore. 547 1.1 jruoho 548 1.1.1.2 jruoho Added support to truncate I/O addresses to 16 bits for Windows 549 1.1.1.2 jruoho compatibility. 550 1.1 jruoho Some ASL code has been seen in the field that inadvertently has bits set 551 1.1 jruoho above bit 15. This feature is optional and is enabled if the BIOS requests 552 1.1 jruoho any Windows OSI strings. It can also be enabled by the host OS. Matthew 553 1.1 jruoho Garrett, Bob Moore. 554 1.1 jruoho 555 1.1 jruoho Added support to limit the maximum time for the ASL Sleep() operator. To 556 1.1 jruoho prevent accidental deep sleeps, limit the maximum time that Sleep() will 557 1.1 jruoho actually sleep. Configurable, the default maximum is two seconds. ACPICA 558 1.1 jruoho bugzilla 854. 559 1.1 jruoho 560 1.1 jruoho Added run-time validation support for the _WDG and_WED Microsoft predefined 561 1.1 jruoho methods. These objects are defined by "Windows Instrumentation", and are not 562 1.1 jruoho part of the ACPI spec. ACPICA BZ 860. 563 1.1 jruoho 564 1.1 jruoho Expanded all statistic counters used during namespace and device 565 1.1 jruoho initialization from 16 to 32 bits in order to support very large namespaces. 566 1.1 jruoho 567 1.1.1.2 jruoho Replaced all instances of %d in printf format specifiers with %u since 568 1.1.1.2 jruoho nearly 569 1.1 jruoho all integers in ACPICA are unsigned. 570 1.1 jruoho 571 1.1.1.2 jruoho Fixed the exception namestring for AE_WAKE_ONLY_GPE. Was incorrectly 572 1.1.1.2 jruoho returned 573 1.1 jruoho as AE_NO_HANDLER. 574 1.1 jruoho 575 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 576 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 577 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 578 1.1.1.2 jruoho a 579 1.1 jruoho much larger code and data size. 580 1.1 jruoho 581 1.1 jruoho Previous Release: 582 1.1 jruoho Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total 583 1.1 jruoho Debug Version: 164.2K Code, 51.5K Data, 215.7K Total 584 1.1 jruoho Current Release: 585 1.1 jruoho Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 586 1.1 jruoho Debug Version: 164.1K Code, 51.5K Data, 215.6K Total 587 1.1 jruoho 588 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 589 1.1 jruoho 590 1.1 jruoho iASL: Added compiler support for the _WDG and_WED Microsoft predefined 591 1.1 jruoho methods. These objects are defined by "Windows Instrumentation", and are not 592 1.1 jruoho part of the ACPI spec. ACPICA BZ 860. 593 1.1 jruoho 594 1.1 jruoho AcpiExec: added option to disable the memory tracking mechanism. The -dt 595 1.1 jruoho option will disable the tracking mechanism, which improves performance 596 1.1 jruoho considerably. 597 1.1 jruoho 598 1.1 jruoho AcpiExec: Restructured the command line options into -d (disable) and -e 599 1.1 jruoho (enable) options. 600 1.1 jruoho 601 1.1 jruoho ---------------------------------------- 602 1.1 jruoho 28 April 2010. Summary of changes for version 20100428: 603 1.1 jruoho 604 1.1 jruoho 1) ACPI CA Core Subsystem: 605 1.1 jruoho 606 1.1 jruoho Implemented GPE support for dynamically loaded ACPI tables. For all GPEs, 607 1.1 jruoho including FADT-based and GPE Block Devices, execute any _PRW methods in the 608 1.1 jruoho new table, and process any _Lxx/_Exx GPE methods in the new table. Any 609 1.1 jruoho runtime GPE that is referenced by an _Lxx/_Exx method in the new table is 610 1.1 jruoho immediately enabled. Handles the FADT-defined GPEs as well as GPE Block 611 1.1 jruoho Devices. Provides compatibility with other ACPI implementations. Two new 612 1.1.1.2 jruoho files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob 613 1.1.1.2 jruoho Moore. 614 1.1 jruoho 615 1.1 jruoho Fixed a regression introduced in version 20100331 within the table manager 616 1.1 jruoho where initial table loading could fail. This was introduced in the fix for 617 1.1 jruoho AcpiReallocateRootTable. Also, renamed some of fields in the table manager 618 1.1 jruoho data structures to clarify their meaning and use. 619 1.1 jruoho 620 1.1 jruoho Fixed a possible allocation overrun during internal object copy in 621 1.1 jruoho AcpiUtCopySimpleObject. The original code did not correctly handle the case 622 1.1 jruoho where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 847. 623 1.1 jruoho 624 1.1 jruoho Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a 625 1.1.1.2 jruoho possible access beyond end-of-allocation. Also, now fully validate 626 1.1.1.2 jruoho descriptor 627 1.1 jruoho (size and type) before output. Lin Ming, Bob Moore. ACPICA BZ 847 628 1.1 jruoho 629 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 630 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 631 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 632 1.1.1.2 jruoho a 633 1.1 jruoho much larger code and data size. 634 1.1 jruoho 635 1.1 jruoho Previous Release: 636 1.1 jruoho Non-Debug Version: 87.9K Code, 18.6K Data, 106.5K Total 637 1.1 jruoho Debug Version: 163.5K Code, 51.3K Data, 214.8K Total 638 1.1 jruoho Current Release: 639 1.1 jruoho Non-Debug Version: 88.4K Code, 18.8K Data, 107.2K Total 640 1.1 jruoho Debug Version: 164.2K Code, 51.5K Data, 215.7K Total 641 1.1 jruoho 642 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 643 1.1 jruoho 644 1.1 jruoho iASL: Implemented Min/Max/Len/Gran validation for address resource 645 1.1 jruoho descriptors. This change implements validation for the address fields that 646 1.1 jruoho are common to all address-type resource descriptors. These checks are 647 1.1 jruoho implemented: Checks for valid Min/Max, length within the Min/Max window, 648 1.1 jruoho valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as per 649 1.1.1.2 jruoho table 6-40 in the ACPI 4.0a specification. Also split the large 650 1.1.1.2 jruoho aslrestype1.c 651 1.1 jruoho and aslrestype2.c files into five new files. ACPICA BZ 840. 652 1.1 jruoho 653 1.1 jruoho iASL: Added support for the _Wxx predefined names. This support was missing 654 1.1 jruoho and these names were not recognized by the compiler as valid predefined 655 1.1 jruoho names. ACPICA BZ 851. 656 1.1 jruoho 657 1.1 jruoho iASL: Added an error for all predefined names that are defined to return no 658 1.1 jruoho value and thus must be implemented as Control Methods. These include all of 659 1.1 jruoho the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous 660 1.1 jruoho names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856. 661 1.1 jruoho 662 1.1 jruoho iASL: Implemented the -ts option to emit hex AML data in ASL format, as an 663 1.1 jruoho ASL Buffer. Allows ACPI tables to be easily included within ASL files, to be 664 1.1 jruoho dynamically loaded via the Load() operator. Also cleaned up output for the - 665 1.1 jruoho ta and -tc options. ACPICA BZ 853. 666 1.1 jruoho 667 1.1 jruoho Tests: Added a new file with examples of extended iASL error checking. 668 1.1 jruoho Demonstrates the advanced error checking ability of the iASL compiler. 669 1.1 jruoho Available at tests/misc/badcode.asl. 670 1.1 jruoho 671 1.1 jruoho ---------------------------------------- 672 1.1 jruoho 31 March 2010. Summary of changes for version 20100331: 673 1.1 jruoho 674 1.1 jruoho 1) ACPI CA Core Subsystem: 675 1.1 jruoho 676 1.1 jruoho Completed a major update for the GPE support in order to improve support for 677 1.1 jruoho shared GPEs and to simplify both host OS and ACPICA code. Added a reference 678 1.1 jruoho count mechanism to support shared GPEs that require multiple device drivers. 679 1.1 jruoho Several external interfaces have changed. One external interface has been 680 1.1 jruoho removed. One new external interface was added. Most of the GPE external 681 1.1 jruoho interfaces now use the GPE spinlock instead of the events mutex (and the 682 1.1 jruoho Flags parameter for many GPE interfaces has been removed.) See the updated 683 1.1 jruoho ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, Rafael 684 1.1 jruoho Wysocki. ACPICA BZ 831. 685 1.1 jruoho 686 1.1 jruoho Changed: 687 1.1 jruoho AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus 688 1.1 jruoho Removed: 689 1.1 jruoho AcpiSetGpeType 690 1.1 jruoho New: 691 1.1 jruoho AcpiSetGpe 692 1.1 jruoho 693 1.1 jruoho Implemented write support for DataTable operation regions. These regions are 694 1.1.1.2 jruoho defined via the DataTableRegion() operator. Previously, only read support 695 1.1.1.2 jruoho was 696 1.1.1.2 jruoho implemented. The ACPI specification allows DataTableRegions to be 697 1.1.1.2 jruoho read/write, 698 1.1 jruoho however. 699 1.1 jruoho 700 1.1 jruoho Implemented a new subsystem option to force a copy of the DSDT to local 701 1.1 jruoho memory. Optionally copy the entire DSDT to local memory (instead of simply 702 1.1 jruoho mapping it.) There are some (albeit very rare) BIOSs that corrupt or replace 703 1.1 jruoho the original DSDT, creating the need for this option. Default is FALSE, do 704 1.1 jruoho not copy the DSDT. 705 1.1 jruoho 706 1.1 jruoho Implemented detection of a corrupted or replaced DSDT. This change adds 707 1.1.1.2 jruoho support to detect a DSDT that has been corrupted and/or replaced from 708 1.1.1.2 jruoho outside 709 1.1 jruoho the OS (by firmware). This is typically catastrophic for the system, but has 710 1.1 jruoho been seen on some machines. Once this problem has been detected, the DSDT 711 1.1 jruoho copy option can be enabled via system configuration. Lin Ming, Bob Moore. 712 1.1 jruoho 713 1.1 jruoho Fixed two problems with AcpiReallocateRootTable during the root table copy. 714 1.1 jruoho When copying the root table to the new allocation, the length used was 715 1.1 jruoho incorrect. The new size was used instead of the current table size, meaning 716 1.1 jruoho too much data was copied. Also, the count of available slots for ACPI tables 717 1.1 jruoho was not set correctly. Alexey Starikovskiy, Bob Moore. 718 1.1 jruoho 719 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 720 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 721 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 722 1.1.1.2 jruoho a 723 1.1 jruoho much larger code and data size. 724 1.1 jruoho 725 1.1 jruoho Previous Release: 726 1.1 jruoho Non-Debug Version: 87.5K Code, 18.4K Data, 105.9K Total 727 1.1 jruoho Debug Version: 163.4K Code, 51.1K Data, 214.5K Total 728 1.1 jruoho Current Release: 729 1.1 jruoho Non-Debug Version: 87.9K Code, 18.6K Data, 106.5K Total 730 1.1 jruoho Debug Version: 163.5K Code, 51.3K Data, 214.8K Total 731 1.1 jruoho 732 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 733 1.1 jruoho 734 1.1 jruoho iASL: Implement limited typechecking for values returned from predefined 735 1.1 jruoho control methods. The type of any returned static (unnamed) object is now 736 1.1 jruoho validated. For example, Return(1). ACPICA BZ 786. 737 1.1 jruoho 738 1.1.1.2 jruoho iASL: Fixed a predefined name object verification regression. Fixes a 739 1.1.1.2 jruoho problem 740 1.1 jruoho introduced in version 20100304. An error is incorrectly generated if a 741 1.1 jruoho predefined name is declared as a static named object with a value defined 742 1.1 jruoho using the keywords "Zero", "One", or "Ones". Lin Ming. 743 1.1 jruoho 744 1.1 jruoho iASL: Added Windows 7 support for the -g option (get local ACPI tables) by 745 1.1 jruoho reducing the requested registry access rights. ACPICA BZ 842. 746 1.1 jruoho 747 1.1 jruoho Disassembler: fixed a possible fault when generating External() statements. 748 1.1 jruoho Introduced in commit ae7d6fd: Properly handle externals with parent-prefix 749 1.1 jruoho (carat). Fixes a string length allocation calculation. Lin Ming. 750 1.1 jruoho 751 1.1 jruoho ---------------------------------------- 752 1.1 jruoho 04 March 2010. Summary of changes for version 20100304: 753 1.1 jruoho 754 1.1 jruoho 1) ACPI CA Core Subsystem: 755 1.1 jruoho 756 1.1 jruoho Fixed a possible problem with the AML Mutex handling function 757 1.1 jruoho AcpiExReleaseMutex where the function could fault under the very rare 758 1.1.1.2 jruoho condition when the interpreter has blocked, the interpreter lock is 759 1.1.1.2 jruoho released, 760 1.1 jruoho the interpreter is then reentered via the same thread, and attempts to 761 1.1.1.2 jruoho acquire an AML mutex that was previously acquired. FreeBSD report 140979. 762 1.1.1.2 jruoho Lin 763 1.1 jruoho Ming. 764 1.1 jruoho 765 1.1 jruoho Implemented additional configuration support for the AML "Debug Object". 766 1.1 jruoho Output from the debug object can now be enabled via a global variable, 767 1.1.1.2 jruoho AcpiGbl_EnableAmlDebugObject. This will assist with remote machine 768 1.1.1.2 jruoho debugging. 769 1.1 jruoho This debug output is now available in the release version of ACPICA instead 770 1.1 jruoho of just the debug version. Also, the entire debug output module can now be 771 1.1 jruoho configured out of the ACPICA build if desired. One new file added, 772 1.1 jruoho executer/exdebug.c. Lin Ming, Bob Moore. 773 1.1 jruoho 774 1.1 jruoho Added header support for the ACPI MCHI table (Management Controller Host 775 1.1.1.2 jruoho Interface Table). This table was added in ACPI 4.0, but the defining 776 1.1.1.2 jruoho document 777 1.1 jruoho has only recently become available. 778 1.1 jruoho 779 1.1 jruoho Standardized output of integer values for ACPICA warnings/errors. Always use 780 1.1 jruoho 0x prefix for hex output, always use %u for unsigned integer decimal output. 781 1.1 jruoho Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 400 782 1.1 jruoho invocations.) These invocations were converted from the original 783 1.1 jruoho ACPI_DEBUG_PRINT invocations and were not consistent. ACPICA BZ 835. 784 1.1 jruoho 785 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 786 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 787 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 788 1.1.1.2 jruoho a 789 1.1 jruoho much larger code and data size. 790 1.1 jruoho 791 1.1 jruoho Previous Release: 792 1.1 jruoho Non-Debug Version: 87.1K Code, 18.0K Data, 105.1K Total 793 1.1 jruoho Debug Version: 163.5K Code, 50.9K Data, 214.4K Total 794 1.1 jruoho Current Release: 795 1.1 jruoho Non-Debug Version: 87.5K Code, 18.4K Data, 105.9K Total 796 1.1 jruoho Debug Version: 163.4K Code, 51.1K Data, 214.5K Total 797 1.1 jruoho 798 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 799 1.1 jruoho 800 1.1 jruoho iASL: Implemented typechecking support for static (non-control method) 801 1.1 jruoho predefined named objects that are declared with the Name() operator. For 802 1.1 jruoho example, the type of this object is now validated to be of type Integer: 803 1.1.1.2 jruoho Name(_BBN, 1). This change migrates the compiler to using the core 804 1.1.1.2 jruoho predefined 805 1.1 jruoho name table instead of maintaining a local version. Added a new file, 806 1.1 jruoho aslpredef.c. ACPICA BZ 832. 807 1.1 jruoho 808 1.1 jruoho Disassembler: Added support for the ACPI 4.0 MCHI table. 809 1.1 jruoho 810 1.1 jruoho ---------------------------------------- 811 1.1 jruoho 21 January 2010. Summary of changes for version 20100121: 812 1.1 jruoho 813 1.1 jruoho 1) ACPI CA Core Subsystem: 814 1.1 jruoho 815 1.1 jruoho Added the 2010 copyright to all module headers and signons. This affects 816 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, the 817 1.1 jruoho tools/utilities, and the test suites. 818 1.1 jruoho 819 1.1.1.2 jruoho Implemented a change to the AcpiGetDevices interface to eliminate 820 1.1.1.2 jruoho unnecessary 821 1.1 jruoho invocations of the _STA method. In the case where a specific _HID is 822 1.1 jruoho requested, do not run _STA until a _HID match is found. This eliminates 823 1.1.1.2 jruoho potentially dozens of _STA calls during a search for a particular 824 1.1.1.2 jruoho device/HID, 825 1.1 jruoho which in turn can improve boot times. ACPICA BZ 828. Lin Ming. 826 1.1 jruoho 827 1.1.1.2 jruoho Implemented an additional repair for predefined method return values. 828 1.1.1.2 jruoho Attempt 829 1.1.1.2 jruoho to repair unexpected NULL elements within returned Package objects. Create 830 1.1.1.2 jruoho an 831 1.1.1.2 jruoho Integer of value zero, a NULL String, or a zero-length Buffer as 832 1.1.1.2 jruoho appropriate. 833 1.1 jruoho ACPICA BZ 818. Lin Ming, Bob Moore. 834 1.1 jruoho 835 1.1 jruoho Removed the obsolete ACPI_INTEGER data type. This type was introduced as the 836 1.1 jruoho code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with 837 1.1 jruoho 64-bit AML integers). It is now obsolete and this change removes it from the 838 1.1 jruoho ACPICA code base, replaced by UINT64. The original typedef has been retained 839 1.1 jruoho for now for compatibility with existing device driver code. ACPICA BZ 824. 840 1.1 jruoho 841 1.1 jruoho Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field in 842 1.1 jruoho the parse tree object. 843 1.1 jruoho 844 1.1.1.2 jruoho Added additional warning options for the gcc-4 generation. Updated the 845 1.1.1.2 jruoho source 846 1.1 jruoho accordingly. This includes some code restructuring to eliminate unreachable 847 1.1 jruoho code, elimination of some gotos, elimination of unused return values, some 848 1.1 jruoho additional casting, and removal of redundant declarations. 849 1.1 jruoho 850 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 851 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 852 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 853 1.1.1.2 jruoho a 854 1.1 jruoho much larger code and data size. 855 1.1 jruoho 856 1.1 jruoho Previous Release: 857 1.1 jruoho Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 858 1.1 jruoho Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 859 1.1 jruoho Current Release: 860 1.1 jruoho Non-Debug Version: 87.1K Code, 18.0K Data, 105.1K Total 861 1.1 jruoho Debug Version: 163.5K Code, 50.9K Data, 214.4K Total 862 1.1 jruoho 863 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 864 1.1 jruoho 865 1.1 jruoho No functional changes for this release. 866 1.1 jruoho 867 1.1 jruoho ---------------------------------------- 868 1.1 jruoho 14 December 2009. Summary of changes for version 20091214: 869 1.1 jruoho 870 1.1 jruoho 1) ACPI CA Core Subsystem: 871 1.1 jruoho 872 1.1 jruoho Enhanced automatic data type conversions for predefined name repairs. This 873 1.1 jruoho change expands the automatic repairs/conversions for predefined name return 874 1.1 jruoho values to make Integers, Strings, and Buffers fully interchangeable. Also, a 875 1.1.1.2 jruoho Buffer can be converted to a Package of Integers if necessary. The 876 1.1.1.2 jruoho nsrepair.c 877 1.1 jruoho module was completely restructured. Lin Ming, Bob Moore. 878 1.1 jruoho 879 1.1.1.2 jruoho Implemented automatic removal of null package elements during predefined 880 1.1.1.2 jruoho name 881 1.1 jruoho repairs. This change will automatically remove embedded and trailing NULL 882 1.1 jruoho package elements from returned package objects that are defined to contain a 883 1.1 jruoho variable number of sub-packages. The driver is then presented with a package 884 1.1 jruoho with no null elements to deal with. ACPICA BZ 819. 885 1.1 jruoho 886 1.1 jruoho Implemented a repair for the predefined _FDE and _GTM names. The expected 887 1.1 jruoho return value for both names is a Buffer of 5 DWORDs. This repair fixes two 888 1.1 jruoho possible problems (both seen in the field), where a package of integers is 889 1.1.1.2 jruoho returned, or a buffer of BYTEs is returned. With assistance from Jung-uk 890 1.1.1.2 jruoho Kim. 891 1.1 jruoho 892 1.1 jruoho Implemented additional module-level code support. This change will properly 893 1.1 jruoho execute module-level code that is not at the root of the namespace (under a 894 1.1 jruoho Device object, etc.). Now executes the code within the current scope instead 895 1.1 jruoho of the root. ACPICA BZ 762. Lin Ming. 896 1.1 jruoho 897 1.1 jruoho Fixed possible mutex acquisition errors when running _REG methods. Fixes a 898 1.1 jruoho problem where mutex errors can occur when running a _REG method that is in 899 1.1 jruoho the same scope as a method-defined operation region or an operation region 900 1.1 jruoho under a module-level IF block. This type of code is rare, so the problem has 901 1.1 jruoho not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore. 902 1.1 jruoho 903 1.1 jruoho Fixed a possible memory leak during module-level code execution. An object 904 1.1 jruoho could be leaked for each block of executed module-level code if the 905 1.1.1.2 jruoho interpreter slack mode is enabled This change deletes any implicitly 906 1.1.1.2 jruoho returned 907 1.1 jruoho object from the module-level code block. Lin Ming. 908 1.1 jruoho 909 1.1 jruoho Removed messages for successful predefined repair(s). The repair mechanism 910 1.1 jruoho was considered too wordy. Now, messages are only unconditionally emitted if 911 1.1 jruoho the return object cannot be repaired. Existing messages for successful 912 1.1 jruoho repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827. 913 1.1 jruoho 914 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 915 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 916 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 917 1.1.1.2 jruoho a 918 1.1 jruoho much larger code and data size. 919 1.1 jruoho 920 1.1 jruoho Previous Release: 921 1.1 jruoho Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 922 1.1 jruoho Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 923 1.1 jruoho Current Release: 924 1.1 jruoho Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 925 1.1 jruoho Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 926 1.1 jruoho 927 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 928 1.1 jruoho 929 1.1.1.2 jruoho iASL: Fixed a regression introduced in 20091112 where intermediate .SRC 930 1.1.1.2 jruoho files 931 1.1 jruoho were no longer automatically removed at the termination of the compile. 932 1.1 jruoho 933 1.1 jruoho acpiexec: Implemented the -f option to specify default region fill value. 934 1.1 jruoho This option specifies the value used to initialize buffers that simulate 935 1.1 jruoho operation regions. Default value is zero. Useful for debugging problems that 936 1.1 jruoho depend on a specific initial value for a region or field. 937 1.1 jruoho 938 1.1 jruoho ---------------------------------------- 939 1.1 jruoho 12 November 2009. Summary of changes for version 20091112: 940 1.1 jruoho 941 1.1 jruoho 1) ACPI CA Core Subsystem: 942 1.1 jruoho 943 1.1 jruoho Implemented a post-order callback to AcpiWalkNamespace. The existing 944 1.1 jruoho interface only has a pre-order callback. This change adds an additional 945 1.1 jruoho parameter for a post-order callback which will be more useful for bus scans. 946 1.1 jruoho ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference. 947 1.1 jruoho 948 1.1 jruoho Modified the behavior of the operation region memory mapping cache for 949 1.1 jruoho SystemMemory. Ensure that the memory mappings created for operation regions 950 1.1 jruoho do not cross 4K page boundaries. Crossing a page boundary while mapping 951 1.1 jruoho regions can cause kernel warnings on some hosts if the pages have different 952 1.1 jruoho attributes. Such regions are probably BIOS bugs, and this is the workaround. 953 1.1 jruoho Linux BZ 14445. Lin Ming. 954 1.1 jruoho 955 1.1 jruoho Implemented an automatic repair for predefined methods that must return 956 1.1.1.2 jruoho sorted lists. This change will repair (by sorting) packages returned by 957 1.1.1.2 jruoho _ALR, 958 1.1.1.2 jruoho _PSS, and _TSS. Drivers can now assume that the packages are correctly 959 1.1.1.2 jruoho sorted 960 1.1 jruoho and do not contain NULL package elements. Adds one new file, 961 1.1 jruoho namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore. 962 1.1 jruoho 963 1.1 jruoho Fixed a possible fault during predefined name validation if a return Package 964 1.1 jruoho object contains NULL elements. Also adds a warning if a NULL element is 965 1.1.1.2 jruoho followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement 966 1.1.1.2 jruoho may 967 1.1 jruoho include repair or removal of all such NULL elements where possible. 968 1.1 jruoho 969 1.1 jruoho Implemented additional module-level executable AML code support. This change 970 1.1 jruoho will execute module-level code that is not at the root of the namespace 971 1.1.1.2 jruoho (under a Device object, etc.) at table load time. Module-level executable 972 1.1.1.2 jruoho AML 973 1.1 jruoho code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming. 974 1.1 jruoho 975 1.1 jruoho Implemented a new internal function to create Integer objects. This function 976 1.1 jruoho simplifies miscellaneous object creation code. ACPICA BZ 823. 977 1.1 jruoho 978 1.1 jruoho Reduced the severity of predefined repair messages, Warning to Info. Since 979 1.1 jruoho the object was successfully repaired, a warning is too severe. Reduced to an 980 1.1.1.2 jruoho info message for now. These messages may eventually be changed to debug- 981 1.1.1.2 jruoho only. 982 1.1 jruoho ACPICA BZ 812. 983 1.1 jruoho 984 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 985 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 986 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 987 1.1.1.2 jruoho a 988 1.1 jruoho much larger code and data size. 989 1.1 jruoho 990 1.1 jruoho Previous Release: 991 1.1 jruoho Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total 992 1.1 jruoho Debug Version: 161.8K Code, 50.6K Data, 212.4K Total 993 1.1 jruoho Current Release: 994 1.1 jruoho Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 995 1.1 jruoho Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 996 1.1 jruoho 997 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 998 1.1 jruoho 999 1.1 jruoho iASL: Implemented Switch() with While(1) so that Break works correctly. This 1000 1.1 jruoho change correctly implements the Switch operator with a surrounding While(1) 1001 1.1 jruoho so that the Break operator works as expected. ACPICA BZ 461. Lin Ming. 1002 1.1 jruoho 1003 1.1 jruoho iASL: Added a message if a package initializer list is shorter than package 1004 1.1 jruoho length. Adds a new remark for a Package() declaration if an initializer list 1005 1.1 jruoho exists, but is shorter than the declared length of the package. Although 1006 1.1 jruoho technically legal, this is probably a coding error and it is seen in the 1007 1.1 jruoho field. ACPICA BZ 815. Lin Ming, Bob Moore. 1008 1.1 jruoho 1009 1.1.1.2 jruoho iASL: Fixed a problem where the compiler could fault after the maximum 1010 1.1.1.2 jruoho number 1011 1.1 jruoho of errors was reached (200). 1012 1.1 jruoho 1013 1.1.1.2 jruoho acpixtract: Fixed a possible warning for pointer cast if the compiler 1014 1.1.1.2 jruoho warning 1015 1.1 jruoho level set very high. 1016 1.1 jruoho 1017 1.1 jruoho ---------------------------------------- 1018 1.1 jruoho 13 October 2009. Summary of changes for version 20091013: 1019 1.1 jruoho 1020 1.1 jruoho 1) ACPI CA Core Subsystem: 1021 1.1 jruoho 1022 1.1 jruoho Fixed a problem where an Operation Region _REG method could be executed more 1023 1.1 jruoho than once. If a custom address space handler is installed by the host before 1024 1.1 jruoho the "initialize operation regions" phase of the ACPICA initialization, any 1025 1.1 jruoho _REG methods for that address space could be executed twice. This change 1026 1.1 jruoho fixes the problem. ACPICA BZ 427. Lin Ming. 1027 1.1 jruoho 1028 1.1 jruoho Fixed a possible memory leak for the Scope() ASL operator. When the exact 1029 1.1 jruoho invocation of "Scope(\)" is executed (change scope to root), one internal 1030 1.1 jruoho operand object was leaked. Lin Ming. 1031 1.1 jruoho 1032 1.1 jruoho Implemented a run-time repair for the _MAT predefined method. If the _MAT 1033 1.1 jruoho return value is defined as a Field object in the AML, and the field 1034 1.1.1.2 jruoho size is less than or equal to the default width of an integer (32 or 1035 1.1.1.2 jruoho 64),_MAT 1036 1.1 jruoho can incorrectly return an Integer instead of a Buffer. ACPICA now 1037 1.1 jruoho automatically repairs this problem. ACPICA BZ 810. 1038 1.1 jruoho 1039 1.1 jruoho Implemented a run-time repair for the _BIF and _BIX predefined methods. The 1040 1.1 jruoho "OEM Information" field is often incorrectly returned as an Integer with 1041 1.1 jruoho value zero if the field is not supported by the platform. This is due to an 1042 1.1 jruoho ambiguity in the ACPI specification. The field should always be a string. 1043 1.1 jruoho ACPICA now automatically repairs this problem by returning a NULL string 1044 1.1 jruoho within the returned Package. ACPICA BZ 807. 1045 1.1 jruoho 1046 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1047 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1048 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1049 1.1.1.2 jruoho a 1050 1.1 jruoho much larger code and data size. 1051 1.1 jruoho 1052 1.1 jruoho Previous Release: 1053 1.1 jruoho Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total 1054 1.1 jruoho Debug Version: 161.7K Code, 50.9K Data, 212.6K Total 1055 1.1 jruoho Current Release: 1056 1.1 jruoho Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total 1057 1.1 jruoho Debug Version: 161.8K Code, 50.6K Data, 212.4K Total 1058 1.1 jruoho 1059 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1060 1.1 jruoho 1061 1.1 jruoho Disassembler: Fixed a problem where references to external symbols that 1062 1.1 jruoho contained one or more parent-prefixes (carats) were not handled correctly, 1063 1.1 jruoho possibly causing a fault. ACPICA BZ 806. Lin Ming. 1064 1.1 jruoho 1065 1.1 jruoho Disassembler: Restructured the code so that all functions that handle 1066 1.1 jruoho external symbols are in a single module. One new file is added, 1067 1.1 jruoho common/dmextern.c. 1068 1.1 jruoho 1069 1.1 jruoho AML Debugger: Added a max count argument for the Batch command (which 1070 1.1 jruoho executes multiple predefined methods within the namespace.) 1071 1.1 jruoho 1072 1.1 jruoho iASL: Updated the compiler documentation (User Reference.) Available at 1073 1.1 jruoho http://www.acpica.org/documentation/. ACPICA BZ 750. 1074 1.1 jruoho 1075 1.1 jruoho AcpiXtract: Updated for Lint and other formatting changes. Close all open 1076 1.1 jruoho files. 1077 1.1 jruoho 1078 1.1 jruoho ---------------------------------------- 1079 1.1 jruoho 03 September 2009. Summary of changes for version 20090903: 1080 1.1 jruoho 1081 1.1 jruoho 1) ACPI CA Core Subsystem: 1082 1.1 jruoho 1083 1.1 jruoho For Windows Vista compatibility, added the automatic execution of an _INI 1084 1.1 jruoho method located at the namespace root (\_INI). This method is executed at 1085 1.1 jruoho table load time. This support is in addition to the automatic execution of 1086 1.1 jruoho \_SB._INI. Lin Ming. 1087 1.1 jruoho 1088 1.1 jruoho Fixed a possible memory leak in the interpreter for AML package objects if 1089 1.1 jruoho the package initializer list is longer than the defined size of the package. 1090 1.1 jruoho This apparently can only happen if the BIOS changes the package size on the 1091 1.1 jruoho fly (seen in a _PSS object), as ASL compilers do not allow this. The 1092 1.1.1.2 jruoho interpreter will truncate the package to the defined size (and issue an 1093 1.1.1.2 jruoho error 1094 1.1.1.2 jruoho message), but previously could leave the extra objects undeleted if they 1095 1.1.1.2 jruoho were 1096 1.1 jruoho pre-created during the argument processing (such is the case if the package 1097 1.1 jruoho consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805. 1098 1.1 jruoho 1099 1.1 jruoho Fixed a problem seen when a Buffer or String is stored to itself via ASL. 1100 1.1 jruoho This has been reported in the field. Previously, ACPICA would zero out the 1101 1.1 jruoho buffer/string. Now, the operation is treated as a noop. Provides Windows 1102 1.1 jruoho compatibility. ACPICA BZ 803. Lin Ming. 1103 1.1 jruoho 1104 1.1 jruoho Removed an extraneous error message for ASL constructs of the form 1105 1.1 jruoho Store(LocalX,LocalX) when LocalX is uninitialized. These curious statements 1106 1.1 jruoho are seen in many BIOSs and are once again treated as NOOPs and no error is 1107 1.1 jruoho emitted when they are encountered. ACPICA BZ 785. 1108 1.1 jruoho 1109 1.1 jruoho Fixed an extraneous warning message if a _DSM reserved method returns a 1110 1.1 jruoho Package object. _DSM can return any type of object, so validation on the 1111 1.1 jruoho return type cannot be performed. ACPICA BZ 802. 1112 1.1 jruoho 1113 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1114 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1115 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1116 1.1.1.2 jruoho a 1117 1.1 jruoho much larger code and data size. 1118 1.1 jruoho 1119 1.1 jruoho Previous Release: 1120 1.1 jruoho Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total 1121 1.1 jruoho Debug Version: 161.6K Code, 50.9K Data, 212.5K Total 1122 1.1 jruoho Current Release: 1123 1.1 jruoho Non-Debug Version: 85.6K Code, 18.0K Data, 103.6K Total 1124 1.1 jruoho Debug Version: 161.7K Code, 50.9K Data, 212.6K Total 1125 1.1 jruoho 1126 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1127 1.1 jruoho 1128 1.1 jruoho iASL: Fixed a problem with the use of the Alias operator and Resource 1129 1.1 jruoho Templates. The correct alias is now constructed and no error is emitted. 1130 1.1 jruoho ACPICA BZ 738. 1131 1.1 jruoho 1132 1.1 jruoho iASL: Implemented the -I option to specify additional search directories for 1133 1.1 jruoho include files. Allows multiple additional search paths for include files. 1134 1.1 jruoho Directories are searched in the order specified on the command line (after 1135 1.1 jruoho the local directory is searched.) ACPICA BZ 800. 1136 1.1 jruoho 1137 1.1 jruoho iASL: Fixed a problem where the full pathname for include files was not 1138 1.1 jruoho emitted for warnings/errors. This caused the IDE support to not work 1139 1.1 jruoho properly. ACPICA BZ 765. 1140 1.1 jruoho 1141 1.1 jruoho iASL: Implemented the -@ option to specify a Windows-style response file 1142 1.1 jruoho containing additional command line options. ACPICA BZ 801. 1143 1.1 jruoho 1144 1.1 jruoho AcpiExec: Added support to load multiple AML files simultaneously (such as a 1145 1.1 jruoho DSDT and multiple SSDTs). Also added support for wildcards within the AML 1146 1.1 jruoho pathname. These features allow all machine tables to be easily loaded and 1147 1.1 jruoho debugged together. ACPICA BZ 804. 1148 1.1 jruoho 1149 1.1 jruoho Disassembler: Added missing support for disassembly of HEST table Error Bank 1150 1.1 jruoho subtables. 1151 1.1 jruoho 1152 1.1 jruoho ---------------------------------------- 1153 1.1 jruoho 30 July 2009. Summary of changes for version 20090730: 1154 1.1 jruoho 1155 1.1 jruoho The ACPI 4.0 implementation for ACPICA is complete with this release. 1156 1.1 jruoho 1157 1.1 jruoho 1) ACPI CA Core Subsystem: 1158 1.1 jruoho 1159 1.1 jruoho ACPI 4.0: Added header file support for all new and changed ACPI tables. 1160 1.1 jruoho Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new 1161 1.1 jruoho for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT, 1162 1.1 jruoho EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There 1163 1.1 jruoho have been some ACPI 4.0 changes to other existing tables. Split the large 1164 1.1 jruoho actbl1.h header into the existing actbl2.h header. ACPICA BZ 774. 1165 1.1 jruoho 1166 1.1.1.2 jruoho ACPI 4.0: Implemented predefined name validation for all new names. There 1167 1.1.1.2 jruoho are 1168 1.1.1.2 jruoho 31 new names in ACPI 4.0. The predefined validation module was split into 1169 1.1.1.2 jruoho two 1170 1.1 jruoho files. The new file is namespace/nsrepair.c. ACPICA BZ 770. 1171 1.1 jruoho 1172 1.1 jruoho Implemented support for so-called "module-level executable code". This is 1173 1.1.1.2 jruoho executable AML code that exists outside of any control method and is 1174 1.1.1.2 jruoho intended 1175 1.1.1.2 jruoho to be executed at table load time. Although illegal since ACPI 2.0, this 1176 1.1.1.2 jruoho type 1177 1.1 jruoho of code still exists and is apparently still being created. Blocks of this 1178 1.1 jruoho code are now detected and executed as intended. Currently, the code blocks 1179 1.1 jruoho must exist under either an If, Else, or While construct; these are the 1180 1.1 jruoho typical cases seen in the field. ACPICA BZ 762. Lin Ming. 1181 1.1 jruoho 1182 1.1 jruoho Implemented an automatic dynamic repair for predefined names that return 1183 1.1 jruoho nested Package objects. This applies to predefined names that are defined to 1184 1.1 jruoho return a variable-length Package of sub-packages. If the number of sub- 1185 1.1 jruoho packages is one, BIOS code is occasionally seen that creates a simple single 1186 1.1 jruoho package with no sub-packages. This code attempts to fix the problem by 1187 1.1 jruoho wrapping a new package object around the existing package. These methods can 1188 1.1 jruoho be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ 1189 1.1 jruoho 790. 1190 1.1 jruoho 1191 1.1 jruoho Fixed a regression introduced in 20090625 for the AcpiGetDevices interface. 1192 1.1.1.2 jruoho The _HID/_CID matching was broken and no longer matched IDs correctly. 1193 1.1.1.2 jruoho ACPICA 1194 1.1 jruoho BZ 793. 1195 1.1 jruoho 1196 1.1 jruoho Fixed a problem with AcpiReset where the reset would silently fail if the 1197 1.1 jruoho register was one of the protected I/O ports. AcpiReset now bypasses the port 1198 1.1 jruoho validation mechanism. This may eventually be driven into the AcpiRead/Write 1199 1.1 jruoho interfaces. 1200 1.1 jruoho 1201 1.1 jruoho Fixed a regression related to the recent update of the AcpiRead/Write 1202 1.1 jruoho interfaces. A sleep/suspend could fail if the optional PM2 Control register 1203 1.1 jruoho does not exist during an attempt to write the Bus Master Arbitration bit. 1204 1.1 jruoho (However, some hosts already delete the code that writes this bit, and the 1205 1.1 jruoho code may in fact be obsolete at this date.) ACPICA BZ 799. 1206 1.1 jruoho 1207 1.1.1.2 jruoho Fixed a problem where AcpiTerminate could fault if inadvertently called 1208 1.1.1.2 jruoho twice 1209 1.1 jruoho in succession. ACPICA BZ 795. 1210 1.1 jruoho 1211 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1212 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1213 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1214 1.1.1.2 jruoho a 1215 1.1 jruoho much larger code and data size. 1216 1.1 jruoho 1217 1.1 jruoho Previous Release: 1218 1.1 jruoho Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total 1219 1.1 jruoho Debug Version: 160.5K Code, 50.6K Data, 211.1K Total 1220 1.1 jruoho Current Release: 1221 1.1 jruoho Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total 1222 1.1 jruoho Debug Version: 161.6K Code, 50.9K Data, 212.5K Total 1223 1.1 jruoho 1224 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1225 1.1 jruoho 1226 1.1 jruoho ACPI 4.0: Implemented disassembler support for all new ACPI tables and 1227 1.1 jruoho changes to existing tables. ACPICA BZ 775. 1228 1.1 jruoho 1229 1.1 jruoho ---------------------------------------- 1230 1.1 jruoho 25 June 2009. Summary of changes for version 20090625: 1231 1.1 jruoho 1232 1.1 jruoho The ACPI 4.0 Specification was released on June 16 and is available at 1233 1.1 jruoho www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will 1234 1.1 jruoho continue for the next few releases. 1235 1.1 jruoho 1236 1.1 jruoho 1) ACPI CA Core Subsystem: 1237 1.1 jruoho 1238 1.1 jruoho ACPI 4.0: Implemented interpreter support for the IPMI operation region 1239 1.1 jruoho address space. Includes support for bi-directional data buffers and an IPMI 1240 1.1 jruoho address space handler (to be installed by an IPMI device driver.) ACPICA BZ 1241 1.1 jruoho 773. Lin Ming. 1242 1.1 jruoho 1243 1.1 jruoho ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes 1244 1.1 jruoho support in both the header files and the disassembler. 1245 1.1 jruoho 1246 1.1 jruoho Completed a major update for the AcpiGetObjectInfo external interface. 1247 1.1 jruoho Changes include: 1248 1.1 jruoho - Support for variable, unlimited length HID, UID, and CID strings. 1249 1.1 jruoho - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) 1250 1.1 jruoho - Call the _SxW power methods on behalf of a device object. 1251 1.1 jruoho - Determine if a device is a PCI root bridge. 1252 1.1 jruoho - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. 1253 1.1 jruoho These changes will require an update to all callers of this interface. See 1254 1.1 jruoho the updated ACPICA Programmer Reference for details. One new source file has 1255 1.1 jruoho been added - utilities/utids.c. ACPICA BZ 368, 780. 1256 1.1 jruoho 1257 1.1 jruoho Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit 1258 1.1 jruoho transfers. The Value parameter has been extended from 32 bits to 64 bits in 1259 1.1.1.2 jruoho order to support new ACPI 4.0 tables. These changes will require an update 1260 1.1.1.2 jruoho to 1261 1.1 jruoho all callers of these interfaces. See the ACPICA Programmer Reference for 1262 1.1 jruoho details. ACPICA BZ 768. 1263 1.1 jruoho 1264 1.1 jruoho Fixed several problems with AcpiAttachData. The handler was not invoked when 1265 1.1 jruoho the host node was deleted. The data sub-object was not automatically deleted 1266 1.1 jruoho when the host node was deleted. The interface to the handler had an unused 1267 1.1 jruoho parameter, this was removed. ACPICA BZ 778. 1268 1.1 jruoho 1269 1.1 jruoho Enhanced the function that dumps ACPI table headers. All non-printable 1270 1.1 jruoho characters in the string fields are now replaced with '?' (Signature, OemId, 1271 1.1 jruoho OemTableId, and CompilerId.) ACPI tables with non-printable characters in 1272 1.1 jruoho these fields are occasionally seen in the field. ACPICA BZ 788. 1273 1.1 jruoho 1274 1.1 jruoho Fixed a problem with predefined method repair code where the code that 1275 1.1 jruoho attempts to repair/convert an object of incorrect type is only executed on 1276 1.1 jruoho the first time the predefined method is called. The mechanism that disables 1277 1.1 jruoho warnings on subsequent calls was interfering with the repair mechanism. 1278 1.1 jruoho ACPICA BZ 781. 1279 1.1 jruoho 1280 1.1 jruoho Fixed a possible memory leak in the predefined validation/repair code when a 1281 1.1 jruoho buffer is automatically converted to an expected string object. 1282 1.1 jruoho 1283 1.1 jruoho Removed obsolete 16-bit files from the distribution and from the current git 1284 1.1 jruoho tree head. ACPICA BZ 776. 1285 1.1 jruoho 1286 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1287 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1288 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1289 1.1.1.2 jruoho a 1290 1.1 jruoho much larger code and data size. 1291 1.1 jruoho 1292 1.1 jruoho Previous Release: 1293 1.1 jruoho Non-Debug Version: 83.4K Code, 17.5K Data, 100.9K Total 1294 1.1 jruoho Debug Version: 158.9K Code, 50.0K Data, 208.9K Total 1295 1.1 jruoho Current Release: 1296 1.1 jruoho Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total 1297 1.1 jruoho Debug Version: 160.5K Code, 50.6K Data, 211.1K Total 1298 1.1 jruoho 1299 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1300 1.1 jruoho 1301 1.1 jruoho ACPI 4.0: iASL and Disassembler - implemented support for the new IPMI 1302 1.1 jruoho operation region keyword. ACPICA BZ 771, 772. Lin Ming. 1303 1.1 jruoho 1304 1.1 jruoho ACPI 4.0: iASL - implemented compile-time validation support for all new 1305 1.1 jruoho predefined names and control methods (31 total). ACPICA BZ 769. 1306 1.1 jruoho 1307 1.1 jruoho ---------------------------------------- 1308 1.1 jruoho 21 May 2009. Summary of changes for version 20090521: 1309 1.1 jruoho 1310 1.1 jruoho 1) ACPI CA Core Subsystem: 1311 1.1 jruoho 1312 1.1 jruoho Disabled the preservation of the SCI enable bit in the PM1 control register. 1313 1.1.1.2 jruoho The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification to 1314 1.1.1.2 jruoho be 1315 1.1 jruoho a "preserved" bit - "OSPM always preserves this bit position", section 1316 1.1 jruoho 4.7.3.2.1. However, some machines fail if this bit is in fact preserved 1317 1.1 jruoho because the bit needs to be explicitly set by the OS as a workaround. No 1318 1.1 jruoho machines fail if the bit is not preserved. Therefore, ACPICA no longer 1319 1.1 jruoho attempts to preserve this bit. 1320 1.1 jruoho 1321 1.1 jruoho Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or 1322 1.1 jruoho incorrectly formed _PRT package could cause a fault. Added validation to 1323 1.1 jruoho ensure that each package element is actually a sub-package. 1324 1.1 jruoho 1325 1.1 jruoho Implemented a new interface to install or override a single control method, 1326 1.1.1.2 jruoho AcpiInstallMethod. This interface is useful when debugging in order to 1327 1.1.1.2 jruoho repair 1328 1.1 jruoho an existing method or to install a missing method without having to override 1329 1.1 jruoho the entire ACPI table. See the ACPICA Programmer Reference for use and 1330 1.1 jruoho examples. Lin Ming, Bob Moore. 1331 1.1 jruoho 1332 1.1 jruoho Fixed several reference count issues with the DdbHandle object that is 1333 1.1 jruoho created from a Load or LoadTable operator. Prevent premature deletion of the 1334 1.1 jruoho object. Also, mark the object as invalid once the table has been unloaded. 1335 1.1 jruoho This is needed because the handle itself may not be deleted after the table 1336 1.1 jruoho unload, depending on whether it has been stored in a named object by the 1337 1.1 jruoho caller. Lin Ming. 1338 1.1 jruoho 1339 1.1 jruoho Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple 1340 1.1 jruoho mutexes of the same sync level are acquired but then not released in strict 1341 1.1.1.2 jruoho opposite order, the internally maintained Current Sync Level becomes 1342 1.1.1.2 jruoho confused 1343 1.1 jruoho and can cause subsequent execution errors. ACPICA BZ 471. 1344 1.1 jruoho 1345 1.1 jruoho Changed the allowable release order for ASL mutex objects. The ACPI 4.0 1346 1.1 jruoho specification has been changed to make the SyncLevel for mutex objects more 1347 1.1 jruoho useful. When releasing a mutex, the SyncLevel of the mutex must now be the 1348 1.1 jruoho same as the current sync level. This makes more sense than the previous rule 1349 1.1 jruoho (SyncLevel less than or equal). This change updates the code to match the 1350 1.1 jruoho specification. 1351 1.1 jruoho 1352 1.1 jruoho Fixed a problem with the local version of the AcpiOsPurgeCache function. The 1353 1.1 jruoho (local) cache must be locked during all cache object deletions. Andrew 1354 1.1 jruoho Baumann. 1355 1.1 jruoho 1356 1.1 jruoho Updated the Load operator to use operation region interfaces. This replaces 1357 1.1 jruoho direct memory mapping with region access calls. Now, all region accesses go 1358 1.1 jruoho through the installed region handler as they should. 1359 1.1 jruoho 1360 1.1 jruoho Simplified and optimized the NsGetNextNode function. Reduced parameter count 1361 1.1 jruoho and reduced code for this frequently used function. 1362 1.1 jruoho 1363 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1364 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1365 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1366 1.1.1.2 jruoho a 1367 1.1 jruoho much larger code and data size. 1368 1.1 jruoho 1369 1.1 jruoho Previous Release: 1370 1.1 jruoho Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 1371 1.1 jruoho Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 1372 1.1 jruoho Current Release: 1373 1.1 jruoho Non-Debug Version: 83.4K Code, 17.5K Data, 100.9K Total 1374 1.1 jruoho Debug Version: 158.9K Code, 50.0K Data, 208.9K Total 1375 1.1 jruoho 1376 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1377 1.1 jruoho 1378 1.1 jruoho Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some problems 1379 1.1 jruoho with sub-table disassembly and handling invalid sub-tables. Attempt recovery 1380 1.1 jruoho after an invalid sub-table ID. 1381 1.1 jruoho 1382 1.1 jruoho ---------------------------------------- 1383 1.1 jruoho 22 April 2009. Summary of changes for version 20090422: 1384 1.1 jruoho 1385 1.1 jruoho 1) ACPI CA Core Subsystem: 1386 1.1 jruoho 1387 1.1 jruoho Fixed a compatibility issue with the recently released I/O port protection 1388 1.1 jruoho mechanism. For windows compatibility, 1) On a port protection violation, 1389 1.1 jruoho simply ignore the request and do not return an exception (allow the control 1390 1.1 jruoho method to continue execution.) 2) If only part of the request overlaps a 1391 1.1.1.2 jruoho protected port, read/write the individual ports that are not protected. 1392 1.1.1.2 jruoho Linux 1393 1.1 jruoho BZ 13036. Lin Ming 1394 1.1 jruoho 1395 1.1.1.2 jruoho Enhanced the execution of the ASL/AML BreakPoint operator so that it 1396 1.1.1.2 jruoho actually 1397 1.1 jruoho breaks into the AML debugger if the debugger is present. This matches the 1398 1.1 jruoho ACPI-defined behavior. 1399 1.1 jruoho 1400 1.1 jruoho Fixed several possible warnings related to the use of the configurable 1401 1.1 jruoho ACPI_THREAD_ID. This type can now be configured as either an integer or a 1402 1.1 jruoho pointer with no warnings. Also fixes several warnings in printf-like 1403 1.1 jruoho statements for the 64-bit build when the type is configured as a pointer. 1404 1.1 jruoho ACPICA BZ 766, 767. 1405 1.1 jruoho 1406 1.1 jruoho Fixed a number of possible warnings when compiling with gcc 4+ (depending on 1407 1.1 jruoho warning options.) Examples include printf formats, aliasing, unused globals, 1408 1.1 jruoho missing prototypes, missing switch default statements, use of non-ANSI 1409 1.1.1.2 jruoho library functions, use of non-ANSI constructs. See generate/unix/Makefile 1410 1.1.1.2 jruoho for 1411 1.1 jruoho a list of warning options used with gcc 3 and 4. ACPICA BZ 735. 1412 1.1 jruoho 1413 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1414 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1415 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1416 1.1.1.2 jruoho a 1417 1.1 jruoho much larger code and data size. 1418 1.1 jruoho 1419 1.1 jruoho Previous Release: 1420 1.1 jruoho Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 1421 1.1 jruoho Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 1422 1.1 jruoho Current Release: 1423 1.1 jruoho Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 1424 1.1 jruoho Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 1425 1.1 jruoho 1426 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1427 1.1 jruoho 1428 1.1.1.2 jruoho iASL: Fixed a generation warning from Bison 2.3 and fixed several warnings 1429 1.1.1.2 jruoho on 1430 1.1 jruoho the 64-bit build. 1431 1.1 jruoho 1432 1.1.1.2 jruoho iASL: Fixed a problem where the Unix/Linux versions of the compiler could 1433 1.1.1.2 jruoho not 1434 1.1 jruoho correctly digest Windows/DOS formatted files (with CR/LF). 1435 1.1 jruoho 1436 1.1 jruoho iASL: Added a new option for "quiet mode" (-va) that produces only the 1437 1.1 jruoho compilation summary, not individual errors and warnings. Useful for large 1438 1.1 jruoho batch compilations. 1439 1.1 jruoho 1440 1.1 jruoho AcpiExec: Implemented a new option (-z) to enable a forced semaphore/mutex 1441 1.1 jruoho timeout that can be used to detect hang conditions during execution of AML 1442 1.1 jruoho code (includes both internal semaphores and AML-defined mutexes and events.) 1443 1.1 jruoho 1444 1.1 jruoho Added new makefiles for the generation of acpica in a generic unix-like 1445 1.1 jruoho environment. These makefiles are intended to generate the acpica tools and 1446 1.1 jruoho utilities from the original acpica git source tree structure. 1447 1.1 jruoho 1448 1.1 jruoho Test Suites: Updated and cleaned up the documentation files. Updated the 1449 1.1 jruoho copyrights to 2009, affecting all source files. Use the new version of iASL 1450 1.1 jruoho with quiet mode. Increased the number of available semaphores in the Windows 1451 1.1 jruoho OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, added 1452 1.1 jruoho an alternate implementation of the semaphore timeout to allow aslts to 1453 1.1 jruoho execute fully on Cygwin. 1454 1.1 jruoho 1455 1.1 jruoho ---------------------------------------- 1456 1.1 jruoho 20 March 2009. Summary of changes for version 20090320: 1457 1.1 jruoho 1458 1.1 jruoho 1) ACPI CA Core Subsystem: 1459 1.1 jruoho 1460 1.1 jruoho Fixed a possible race condition between AcpiWalkNamespace and dynamic table 1461 1.1.1.2 jruoho unloads. Added a reader/writer locking mechanism to allow multiple 1462 1.1.1.2 jruoho concurrent 1463 1.1.1.2 jruoho namespace walks (readers), but block a dynamic table unload until it can 1464 1.1.1.2 jruoho gain 1465 1.1 jruoho exclusive write access to the namespace. This fixes a problem where a table 1466 1.1 jruoho unload could (possibly catastrophically) delete the portion of the namespace 1467 1.1 jruoho that is currently being examined by a walk. Adds a new file, utlock.c, that 1468 1.1 jruoho implements the reader/writer lock mechanism. ACPICA BZ 749. 1469 1.1 jruoho 1470 1.1 jruoho Fixed a regression introduced in version 20090220 where a change to the FADT 1471 1.1 jruoho handling could cause the ACPICA subsystem to access non-existent I/O ports. 1472 1.1 jruoho 1473 1.1 jruoho Modified the handling of FADT register and table (FACS/DSDT) addresses. The 1474 1.1 jruoho FADT can contain both 32-bit and 64-bit versions of these addresses. 1475 1.1 jruoho Previously, the 64-bit versions were favored, meaning that if both 32 and 64 1476 1.1 jruoho versions were valid, but not equal, the 64-bit version was used. This was 1477 1.1 jruoho found to cause some machines to fail. Now, in this case, the 32-bit version 1478 1.1 jruoho is used instead. This now matches the Windows behavior. 1479 1.1 jruoho 1480 1.1 jruoho Implemented a new mechanism to protect certain I/O ports. Provides Microsoft 1481 1.1 jruoho compatibility and protects the standard PC I/O ports from access via AML 1482 1.1 jruoho code. Adds a new file, hwvalid.c 1483 1.1 jruoho 1484 1.1 jruoho Fixed a possible extraneous warning message from the FADT support. The 1485 1.1 jruoho message warns of a 32/64 length mismatch between the legacy and GAS 1486 1.1 jruoho definitions for a register. 1487 1.1 jruoho 1488 1.1 jruoho Removed the obsolete AcpiOsValidateAddress OSL interface. This interface is 1489 1.1 jruoho made obsolete by the port protection mechanism above. It was previously used 1490 1.1 jruoho to validate the entire address range of an operation region, which could be 1491 1.1 jruoho incorrect if the range included illegal ports, but fields within the 1492 1.1 jruoho operation region did not actually access those ports. Validation is now 1493 1.1 jruoho performed on a per-field basis instead of the entire region. 1494 1.1 jruoho 1495 1.1 jruoho Modified the handling of the PM1 Status Register ignored bit (bit 11.) 1496 1.1 jruoho Ignored bits must be "preserved" according to the ACPI spec. Usually, this 1497 1.1 jruoho means a read/modify/write when writing to the register. However, for status 1498 1.1.1.2 jruoho registers, writing a one means clear the event. Writing a zero means 1499 1.1.1.2 jruoho preserve 1500 1.1 jruoho the event (do not clear.) This behavior is clarified in the ACPI 4.0 spec, 1501 1.1 jruoho and the ACPICA code now simply always writes a zero to the ignored bit. 1502 1.1 jruoho 1503 1.1 jruoho Modified the handling of ignored bits for the PM1 A/B Control Registers. As 1504 1.1 jruoho per the ACPI specification, for the control registers, preserve 1505 1.1 jruoho (read/modify/write) all bits that are defined as either reserved or ignored. 1506 1.1 jruoho 1507 1.1 jruoho Updated the handling of write-only bits in the PM1 A/B Control Registers. 1508 1.1 jruoho When reading the register, zero the write-only bits as per the ACPI spec. 1509 1.1 jruoho ACPICA BZ 443. Lin Ming. 1510 1.1 jruoho 1511 1.1 jruoho Removed "Linux" from the list of supported _OSI strings. Linux no longer 1512 1.1 jruoho wants to reply true to this request. The Windows strings are the only paths 1513 1.1 jruoho through the AML that are tested and known to work properly. 1514 1.1 jruoho 1515 1.1 jruoho Previous Release: 1516 1.1 jruoho Non-Debug Version: 82.0K Code, 17.5K Data, 99.5K Total 1517 1.1 jruoho Debug Version: 156.9K Code, 49.8K Data, 206.7K Total 1518 1.1 jruoho Current Release: 1519 1.1 jruoho Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 1520 1.1 jruoho Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 1521 1.1 jruoho 1522 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1523 1.1 jruoho 1524 1.1 jruoho Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c and 1525 1.1 jruoho aetables.c 1526 1.1 jruoho 1527 1.1 jruoho ---------------------------------------- 1528 1.1 jruoho 20 February 2009. Summary of changes for version 20090220: 1529 1.1 jruoho 1530 1.1 jruoho 1) ACPI CA Core Subsystem: 1531 1.1 jruoho 1532 1.1 jruoho Optimized the ACPI register locking. Removed locking for reads from the ACPI 1533 1.1 jruoho bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is 1534 1.1 jruoho not required when reading the single-bit registers. The 1535 1.1 jruoho AcpiGetRegisterUnlocked function is no longer needed and has been removed. 1536 1.1 jruoho This will improve performance for reads on these registers. ACPICA BZ 760. 1537 1.1 jruoho 1538 1.1 jruoho Fixed the parameter validation for AcpiRead/Write. Now return 1539 1.1.1.2 jruoho AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS 1540 1.1.1.2 jruoho if 1541 1.1 jruoho the register has an address of zero. Previously, these cases simply returned 1542 1.1 jruoho AE_OK. For optional registers such as PM1B status/enable/control, the caller 1543 1.1 jruoho should check for a valid register address before calling. ACPICA BZ 748. 1544 1.1 jruoho 1545 1.1 jruoho Renamed the external ACPI bit register access functions. Renamed 1546 1.1 jruoho AcpiGetRegister and AcpiSetRegister to clarify the purpose of these 1547 1.1 jruoho functions. The new names are AcpiReadBitRegister and AcpiWriteBitRegister. 1548 1.1 jruoho Also, restructured the code for these functions by simplifying the code path 1549 1.1 jruoho and condensing duplicate code to reduce code size. 1550 1.1 jruoho 1551 1.1 jruoho Added new functions to transparently handle the possibly split PM1 A/B 1552 1.1 jruoho registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two functions 1553 1.1.1.2 jruoho now handle the split registers for PM1 Status, Enable, and Control. ACPICA 1554 1.1.1.2 jruoho BZ 1555 1.1 jruoho 746. 1556 1.1 jruoho 1557 1.1 jruoho Added a function to handle the PM1 control registers, AcpiHwWritePm1Control. 1558 1.1.1.2 jruoho This function writes both of the PM1 control registers (A/B). These 1559 1.1.1.2 jruoho registers 1560 1.1 jruoho are different than the PM1 A/B status and enable registers in that different 1561 1.1 jruoho values can be written to the A/B registers. Most notably, the SLP_TYP bits 1562 1.1.1.2 jruoho can be different, as per the values returned from the _Sx predefined 1563 1.1.1.2 jruoho methods. 1564 1.1 jruoho 1565 1.1 jruoho Removed an extra register write within AcpiHwClearAcpiStatus. This function 1566 1.1 jruoho was writing an optional PM1B status register twice. The existing call to the 1567 1.1 jruoho low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 A/B 1568 1.1 jruoho register. ACPICA BZ 751. 1569 1.1 jruoho 1570 1.1.1.2 jruoho Split out the PM1 Status registers from the FADT. Added new globals for 1571 1.1.1.2 jruoho these 1572 1.1 jruoho registers (A/B), similar to the way the PM1 Enable registers are handled. 1573 1.1 jruoho Instead of overloading the FADT Event Register blocks. This makes the code 1574 1.1 jruoho clearer and less prone to error. 1575 1.1 jruoho 1576 1.1.1.2 jruoho Fixed the warning message for when the platform contains too many ACPI 1577 1.1.1.2 jruoho tables 1578 1.1.1.2 jruoho for the default size of the global root table data structure. The 1579 1.1.1.2 jruoho calculation 1580 1.1 jruoho for the truncation value was incorrect. 1581 1.1 jruoho 1582 1.1 jruoho Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this 1583 1.1 jruoho obsolete macro, since it is now a simple reference to ->common.type. There 1584 1.1 jruoho were about 150 invocations of the macro across 41 files. ACPICA BZ 755. 1585 1.1 jruoho 1586 1.1 jruoho Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as 1587 1.1 jruoho TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to 1588 1.1 jruoho simply SLEEP_TYPE. ACPICA BZ 754. 1589 1.1 jruoho 1590 1.1 jruoho Conditionally compile the AcpiSetFirmwareWakingVector64 function. This 1591 1.1 jruoho function is only needed on 64-bit host operating systems and is thus not 1592 1.1 jruoho included for 32-bit hosts. 1593 1.1 jruoho 1594 1.1.1.2 jruoho Debug output: print the input and result for invocations of the _OSI 1595 1.1.1.2 jruoho reserved 1596 1.1 jruoho control method via the ACPI_LV_INFO debug level. Also, reduced some of the 1597 1.1 jruoho verbosity of this debug level. Len Brown. 1598 1.1 jruoho 1599 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1600 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20090123: 1619 1.1 jruoho 1620 1.1 jruoho 1) ACPI CA Core Subsystem: 1621 1.1 jruoho 1622 1.1 jruoho Added the 2009 copyright to all module headers and signons. This affects 1623 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, and 1624 1.1 jruoho the tools/utilities. 1625 1.1 jruoho 1626 1.1 jruoho Implemented a change to allow the host to override any ACPI table, including 1627 1.1.1.2 jruoho dynamically loaded tables. Previously, only the DSDT could be replaced by 1628 1.1.1.2 jruoho the 1629 1.1 jruoho host. With this change, the AcpiOsTableOverride interface is called for each 1630 1.1 jruoho table found in the RSDT/XSDT during ACPICA initialization, and also whenever 1631 1.1 jruoho a table is dynamically loaded via the AML Load operator. 1632 1.1 jruoho 1633 1.1 jruoho Updated FADT flag definitions, especially the Boot Architecture flags. 1634 1.1 jruoho 1635 1.1 jruoho Debugger: For the Find command, automatically pad the input ACPI name with 1636 1.1 jruoho underscores if the name is shorter than 4 characters. This enables a match 1637 1.1 jruoho with the actual namespace entry which is itself padded with underscores. 1638 1.1 jruoho 1639 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1640 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1641 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1642 1.1.1.2 jruoho a 1643 1.1 jruoho much larger code and data size. 1644 1.1 jruoho 1645 1.1 jruoho Previous Release: 1646 1.1 jruoho Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total 1647 1.1 jruoho Debug Version: 157.1K Code, 49.7K Data, 206.8K Total 1648 1.1 jruoho Current Release: 1649 1.1 jruoho Non-Debug Version: 82.3K Code, 17.5K Data, 99.8K Total 1650 1.1 jruoho Debug Version: 157.3K Code, 49.8K Data, 207.1K Total 1651 1.1 jruoho 1652 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1653 1.1 jruoho 1654 1.1 jruoho Fix build error under Bison-2.4. 1655 1.1 jruoho 1656 1.1 jruoho Dissasembler: Enhanced FADT support. Added decoding of the Boot Architecture 1657 1.1 jruoho flags. Now decode all flags, regardless of the FADT version. Flag output 1658 1.1 jruoho includes the FADT version which first defined each flag. 1659 1.1 jruoho 1660 1.1 jruoho The iASL -g option now dumps the RSDT to a file (in addition to the FADT and 1661 1.1 jruoho DSDT). Windows only. 1662 1.1 jruoho 1663 1.1 jruoho ---------------------------------------- 1664 1.1 jruoho 04 December 2008. Summary of changes for version 20081204: 1665 1.1 jruoho 1666 1.1 jruoho 1) ACPI CA Core Subsystem: 1667 1.1 jruoho 1668 1.1 jruoho The ACPICA Programmer Reference has been completely updated and revamped for 1669 1.1 jruoho this release. This includes updates to the external interfaces, OSL 1670 1.1 jruoho interfaces, the overview sections, and the debugger reference. 1671 1.1 jruoho 1672 1.1 jruoho Several new ACPICA interfaces have been implemented and documented in the 1673 1.1 jruoho programmer reference: 1674 1.1 jruoho AcpiReset - Writes the reset value to the FADT-defined reset register. 1675 1.1 jruoho AcpiDisableAllGpes - Disable all available GPEs. 1676 1.1 jruoho AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs. 1677 1.1 jruoho AcpiGetGpeDevice - Get the GPE block device associated with a GPE. 1678 1.1 jruoho AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs. 1679 1.1 jruoho AcpiRead - Low-level read ACPI register (was HwLowLevelRead.) 1680 1.1 jruoho AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.) 1681 1.1 jruoho 1682 1.1 jruoho Most of the public ACPI hardware-related interfaces have been moved to a new 1683 1.1 jruoho file, components/hardware/hwxface.c 1684 1.1 jruoho 1685 1.1 jruoho Enhanced the FADT parsing and low-level ACPI register access: The ACPI 1686 1.1 jruoho register lengths within the FADT are now used, and the low level ACPI 1687 1.1 jruoho register access no longer hardcodes the ACPI register lengths. Given that 1688 1.1.1.2 jruoho there may be some risk in actually trusting the FADT register lengths, a 1689 1.1.1.2 jruoho run- 1690 1.1 jruoho time option was added to fall back to the default hardcoded lengths if the 1691 1.1 jruoho FADT proves to contain incorrect values - UseDefaultRegisterWidths. This 1692 1.1 jruoho option is set to true for now, and a warning is issued if a suspicious FADT 1693 1.1 jruoho register length is overridden with the default value. 1694 1.1 jruoho 1695 1.1 jruoho Fixed a reference count issue in NsRepairObject. This problem was introduced 1696 1.1 jruoho in version 20081031 as part of a fix to repair Buffer objects within 1697 1.1 jruoho Packages. Lin Ming. 1698 1.1 jruoho 1699 1.1 jruoho Added semaphore support to the Linux/Unix application OS-services layer 1700 1.1 jruoho (OSL). ACPICA BZ 448. Lin Ming. 1701 1.1 jruoho 1702 1.1.1.2 jruoho Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes 1703 1.1.1.2 jruoho will 1704 1.1 jruoho be implemented in the OSL, or will binary semaphores be used instead. 1705 1.1 jruoho 1706 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1707 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1708 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1709 1.1.1.2 jruoho a 1710 1.1 jruoho much larger code and data size. 1711 1.1 jruoho 1712 1.1 jruoho Previous Release: 1713 1.1 jruoho Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total 1714 1.1 jruoho Debug Version: 156.4K Code, 49.4K Data, 205.8K Total 1715 1.1 jruoho Current Release: 1716 1.1 jruoho Non-Debug Version: 82.3K Code, 17.4K Data, 99.7K Total 1717 1.1 jruoho Debug Version: 157.1K Code, 49.7K Data, 206.8K Total 1718 1.1 jruoho 1719 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1720 1.1 jruoho 1721 1.1.1.2 jruoho iASL: Completed the '-e' option to include additional ACPI tables in order 1722 1.1.1.2 jruoho to 1723 1.1 jruoho aid with disassembly and External statement generation. ACPICA BZ 742. Lin 1724 1.1 jruoho Ming. 1725 1.1 jruoho 1726 1.1 jruoho iASL: Removed the "named object in while loop" error. The compiler cannot 1727 1.1 jruoho determine how many times a loop will execute. ACPICA BZ 730. 1728 1.1 jruoho 1729 1.1 jruoho Disassembler: Implemented support for FADT revision 2 (MS extension). ACPICA 1730 1.1 jruoho BZ 743. 1731 1.1 jruoho 1732 1.1 jruoho Disassembler: Updates for several ACPI data tables (HEST, EINJ, and MCFG). 1733 1.1 jruoho 1734 1.1 jruoho ---------------------------------------- 1735 1.1 jruoho 31 October 2008. Summary of changes for version 20081031: 1736 1.1 jruoho 1737 1.1 jruoho 1) ACPI CA Core Subsystem: 1738 1.1 jruoho 1739 1.1.1.2 jruoho Restructured the ACPICA header files into public/private. acpi.h now 1740 1.1.1.2 jruoho includes 1741 1.1 jruoho only the "public" acpica headers. All other acpica headers are "private" and 1742 1.1 jruoho should not be included by acpica users. One new file, accommon.h is used to 1743 1.1 jruoho include the commonly used private headers for acpica code generation. Future 1744 1.1 jruoho plans include moving all private headers to a new subdirectory. 1745 1.1 jruoho 1746 1.1 jruoho Implemented an automatic Buffer->String return value conversion for 1747 1.1 jruoho predefined ACPI methods. For these methods (such as _BIF), added automatic 1748 1.1 jruoho conversion for return objects that are required to be a String, but a Buffer 1749 1.1 jruoho was found instead. This can happen when reading string battery data from an 1750 1.1 jruoho operation region, because it used to be difficult to convert the data from 1751 1.1 jruoho buffer to string from within the ASL. Ensures that the host OS is provided 1752 1.1 jruoho with a valid null-terminated string. Linux BZ 11822. 1753 1.1 jruoho 1754 1.1 jruoho Updated the FACS waking vector interfaces. Split AcpiSetFirmwareWakingVector 1755 1.1 jruoho into two: one for the 32-bit vector, another for the 64-bit vector. This is 1756 1.1 jruoho required because the host OS must setup the wake much differently for each 1757 1.1.1.2 jruoho vector (real vs. protected mode, etc.) and the interface itself should not 1758 1.1.1.2 jruoho be 1759 1.1 jruoho deciding which vector to use. Also, eliminated the GetFirmwareWakingVector 1760 1.1 jruoho interface, as it served no purpose (only the firmware reads the vector, OS 1761 1.1 jruoho only writes the vector.) ACPICA BZ 731. 1762 1.1 jruoho 1763 1.1 jruoho Implemented a mechanism to escape infinite AML While() loops. Added a loop 1764 1.1 jruoho counter to force exit from AML While loops if the count becomes too large. 1765 1.1 jruoho This can occur in poorly written AML when the hardware does not respond 1766 1.1 jruoho within a while loop and the loop does not implement a timeout. The maximum 1767 1.1 jruoho loop count is configurable. A new exception code is returned when a loop is 1768 1.1 jruoho broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore. 1769 1.1 jruoho 1770 1.1 jruoho Optimized the execution of AML While loops. Previously, a control state 1771 1.1 jruoho object was allocated and freed for each execution of the loop. The 1772 1.1 jruoho optimization is to simply reuse the control state for each iteration. This 1773 1.1 jruoho speeds up the raw loop execution time by about 5%. 1774 1.1 jruoho 1775 1.1 jruoho Enhanced the implicit return mechanism. For Windows compatibility, return an 1776 1.1 jruoho implicit integer of value zero for methods that contain no executable code. 1777 1.1 jruoho Such methods are seen in the field as stubs (presumably), and can cause 1778 1.1 jruoho drivers to fail if they expect a return value. Lin Ming. 1779 1.1 jruoho 1780 1.1 jruoho Allow multiple backslashes as root prefixes in namepaths. In a fully 1781 1.1 jruoho qualified namepath, allow multiple backslash prefixes. This can happen (and 1782 1.1 jruoho is seen in the field) because of the use of a double-backslash in strings 1783 1.1 jruoho (since backslash is the escape character) causing confusion. ACPICA BZ 739 1784 1.1 jruoho Lin Ming. 1785 1.1 jruoho 1786 1.1 jruoho Emit a warning if two different FACS or DSDT tables are discovered in the 1787 1.1 jruoho FADT. Checks if there are two valid but different addresses for the FACS and 1788 1.1 jruoho DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.) 1789 1.1 jruoho 1790 1.1 jruoho Consolidated the method argument count validation code. Merged the code that 1791 1.1 jruoho validates control method argument counts into the predefined validation 1792 1.1 jruoho module. Eliminates possible multiple warnings for incorrect argument counts. 1793 1.1 jruoho 1794 1.1 jruoho Implemented ACPICA example code. Includes code for ACPICA initialization, 1795 1.1 jruoho handler installation, and calling a control method. Available at 1796 1.1 jruoho source/tools/examples. 1797 1.1 jruoho 1798 1.1 jruoho Added a global pointer for FACS table to simplify internal FACS access. Use 1799 1.1.1.2 jruoho the global pointer instead of using AcpiGetTableByIndex for each FACS 1800 1.1.1.2 jruoho access. 1801 1.1 jruoho This simplifies the code for the Global Lock and the Firmware Waking 1802 1.1 jruoho Vector(s). 1803 1.1 jruoho 1804 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1805 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1806 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1807 1.1.1.2 jruoho a 1808 1.1 jruoho much larger code and data size. 1809 1.1 jruoho 1810 1.1 jruoho Previous Release: 1811 1.1 jruoho Non-Debug Version: 81.2K Code, 17.0K Data, 98.2K Total 1812 1.1 jruoho Debug Version: 155.8K Code, 49.1K Data, 204.9K Total 1813 1.1 jruoho Current Release: 1814 1.1 jruoho Non-Debug Version: 81.7K Code, 17.3K Data, 99.0K Total 1815 1.1 jruoho Debug Version: 156.4K Code, 49.4K Data, 205.8K Total 1816 1.1 jruoho 1817 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 1818 1.1 jruoho 1819 1.1 jruoho iASL: Improved disassembly of external method calls. Added the -e option to 1820 1.1.1.2 jruoho allow the inclusion of additional ACPI tables to help with the disassembly 1821 1.1.1.2 jruoho of 1822 1.1 jruoho method invocations and the generation of external declarations during the 1823 1.1 jruoho disassembly. Certain external method invocations cannot be disassembled 1824 1.1 jruoho properly without the actual declaration of the method. Use the -e option to 1825 1.1 jruoho include the table where the external method(s) are actually declared. Most 1826 1.1 jruoho useful for disassembling SSDTs that make method calls back to the master 1827 1.1 jruoho DSDT. Lin Ming. Example: To disassemble an SSDT with calls to DSDT: iasl -d 1828 1.1 jruoho -e dsdt.aml ssdt1.aml 1829 1.1 jruoho 1830 1.1 jruoho iASL: Fix to allow references to aliases within ASL namepaths. Fixes a 1831 1.1 jruoho problem where the use of an alias within a namepath would result in a not 1832 1.1 jruoho found error or cause the compiler to fault. Also now allows forward 1833 1.1 jruoho references from the Alias operator itself. ACPICA BZ 738. 1834 1.1 jruoho 1835 1.1 jruoho ---------------------------------------- 1836 1.1 jruoho 26 September 2008. Summary of changes for version 20080926: 1837 1.1 jruoho 1838 1.1 jruoho 1) ACPI CA Core Subsystem: 1839 1.1 jruoho 1840 1.1 jruoho Designed and implemented a mechanism to validate predefined ACPI methods and 1841 1.1.1.2 jruoho objects. This code validates the predefined ACPI objects (objects whose 1842 1.1.1.2 jruoho names 1843 1.1 jruoho start with underscore) that appear in the namespace, at the time they are 1844 1.1 jruoho evaluated. The argument count and the type of the returned object are 1845 1.1 jruoho validated against the ACPI specification. The purpose of this validation is 1846 1.1 jruoho to detect problems with the BIOS-implemented predefined ACPI objects before 1847 1.1.1.2 jruoho the results are returned to the ACPI-related drivers. Future enhancements 1848 1.1.1.2 jruoho may 1849 1.1 jruoho include actual repair of incorrect return objects where possible. Two new 1850 1.1 jruoho files are nspredef.c and acpredef.h. 1851 1.1 jruoho 1852 1.1 jruoho Fixed a fault in the AML parser if a memory allocation fails during the Op 1853 1.1 jruoho completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492. 1854 1.1 jruoho 1855 1.1 jruoho Fixed an issue with implicit return compatibility. This change improves the 1856 1.1 jruoho implicit return mechanism to be more compatible with the MS interpreter. Lin 1857 1.1 jruoho Ming, ACPICA BZ 349. 1858 1.1 jruoho 1859 1.1 jruoho Implemented support for zero-length buffer-to-string conversions. Allow zero 1860 1.1 jruoho length strings during interpreter buffer-to-string conversions. For example, 1861 1.1 jruoho during the ToDecimalString and ToHexString operators, as well as implicit 1862 1.1 jruoho conversions. Fiodor Suietov, ACPICA BZ 585. 1863 1.1 jruoho 1864 1.1 jruoho Fixed two possible memory leaks in the error exit paths of 1865 1.1 jruoho AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions are 1866 1.1 jruoho similar in that they use a stack of state objects in order to eliminate 1867 1.1 jruoho recursion. The stack must be fully unwound and deallocated if an error 1868 1.1 jruoho occurs. Lin Ming. ACPICA BZ 383. 1869 1.1 jruoho 1870 1.1.1.2 jruoho Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the 1871 1.1.1.2 jruoho global 1872 1.1 jruoho ACPI register table. This bit does not exist and is unused. Lin Ming, Bob 1873 1.1 jruoho Moore ACPICA BZ 442. 1874 1.1 jruoho 1875 1.1 jruoho Removed the obsolete version number in module headers. Removed the 1876 1.1 jruoho "$Revision" number that appeared in each module header. This version number 1877 1.1 jruoho was useful under SourceSafe and CVS, but has no meaning under git. It is not 1878 1.1 jruoho only incorrect, it could also be misleading. 1879 1.1 jruoho 1880 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1881 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1882 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 1883 1.1.1.2 jruoho a 1884 1.1 jruoho much larger code and data size. 1885 1.1 jruoho 1886 1.1 jruoho Previous Release: 1887 1.1 jruoho Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total 1888 1.1 jruoho Debug Version: 153.7K Code, 48.2K Data, 201.9K Total 1889 1.1 jruoho Current Release: 1890 1.1 jruoho Non-Debug Version: 81.2K Code, 17.0K Data, 98.2K Total 1891 1.1 jruoho Debug Version: 155.8K Code, 49.1K Data, 204.9K Total 1892 1.1 jruoho 1893 1.1 jruoho ---------------------------------------- 1894 1.1 jruoho 29 August 2008. Summary of changes for version 20080829: 1895 1.1 jruoho 1896 1.1 jruoho 1) ACPI CA Core Subsystem: 1897 1.1 jruoho 1898 1.1 jruoho Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type 1899 1.1 jruoho Reference. Changes include the elimination of cheating on the Object field 1900 1.1 jruoho for the DdbHandle subtype, addition of a reference class field to 1901 1.1.1.2 jruoho differentiate the various reference types (instead of an AML opcode), and 1902 1.1.1.2 jruoho the 1903 1.1 jruoho cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723 1904 1.1 jruoho 1905 1.1 jruoho Reduce an error to a warning for an incorrect method argument count. 1906 1.1 jruoho Previously aborted with an error if too few arguments were passed to a 1907 1.1.1.2 jruoho control method via the external ACPICA interface. Now issue a warning 1908 1.1.1.2 jruoho instead 1909 1.1 jruoho and continue. Handles the case where the method inadvertently declares too 1910 1.1 jruoho many arguments, but does not actually use the extra ones. Applies mainly to 1911 1.1 jruoho the predefined methods. Lin Ming. Linux BZ 11032. 1912 1.1 jruoho 1913 1.1.1.2 jruoho Disallow the evaluation of named object types with no intrinsic value. 1914 1.1.1.2 jruoho Return 1915 1.1.1.2 jruoho AE_TYPE for objects that have no value and therefore evaluation is 1916 1.1.1.2 jruoho undefined: 1917 1.1 jruoho Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation of 1918 1.1 jruoho these types were allowed, but an exception would be generated at some point 1919 1.1 jruoho during the evaluation. Now, the error is generated up front. 1920 1.1 jruoho 1921 1.1 jruoho Fixed a possible memory leak in the AcpiNsGetExternalPathname function 1922 1.1 jruoho (nsnames.c). Fixes a leak in the error exit path. 1923 1.1 jruoho 1924 1.1.1.2 jruoho Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These 1925 1.1.1.2 jruoho debug 1926 1.1.1.2 jruoho levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and 1927 1.1.1.2 jruoho ACPI_EXCEPTION 1928 1.1 jruoho interfaces. Also added ACPI_DB_EVENTS to correspond with the existing 1929 1.1 jruoho ACPI_LV_EVENTS. 1930 1.1 jruoho 1931 1.1 jruoho Removed obsolete and/or unused exception codes from the acexcep.h header. 1932 1.1 jruoho There is the possibility that certain device drivers may be affected if they 1933 1.1 jruoho use any of these exceptions. 1934 1.1 jruoho 1935 1.1 jruoho The ACPICA documentation has been added to the public git source tree, under 1936 1.1 jruoho acpica/documents. Included are the ACPICA programmer reference, the iASL 1937 1.1 jruoho compiler reference, and the changes.txt release logfile. 1938 1.1 jruoho 1939 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 1940 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

ACPI 3.0 1955 1.1 jruoho defines _SCP with 3 arguments. Previous versions defined it with only 1 1956 1.1 jruoho argument. iASL now allows both definitions. 1957 1.1 jruoho 1958 1.1 jruoho iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for zero- 1959 1.1 jruoho length subtables when disassembling ACPI tables. Also fixed a couple of 1960 1.1 jruoho errors where a full 16-bit table type field was not extracted from the input 1961 1.1 jruoho properly. 1962 1.1 jruoho 1963 1.1 jruoho acpisrc: Improve comment counting mechanism for generating source code 1964 1.1 jruoho statistics. Count first and last lines of multi-line comments as whitespace, 1965 1.1 jruoho not comment lines. Handle Linux legal header in addition to standard acpica 1966 1.1 jruoho header. 1967 1.1 jruoho 1968 1.1 jruoho ---------------------------------------- 1969 1.1 jruoho 1970 1.1 jruoho 29 July 2008. Summary of changes for version 20080729: 1971 1.1 jruoho 1972 1.1 jruoho 1) ACPI CA Core Subsystem: 1973 1.1 jruoho 1974 1.1 jruoho Fix a possible deadlock in the GPE dispatch. Remove call to 1975 1.1.1.2 jruoho AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will 1976 1.1.1.2 jruoho attempt 1977 1.1 jruoho to acquire the GPE lock but can deadlock since the GPE lock is already held 1978 1.1 jruoho at dispatch time. This code was introduced in version 20060831 as a response 1979 1.1 jruoho to Linux BZ 6881 and has since been removed from Linux. 1980 1.1 jruoho 1981 1.1.1.2 jruoho Add a function to dereference returned reference objects. Examines the 1982 1.1.1.2 jruoho return 1983 1.1 jruoho object from a call to AcpiEvaluateObject. Any Index or RefOf references are 1984 1.1 jruoho automatically dereferenced in an attempt to return something useful (these 1985 1.1 jruoho reference types cannot be converted into an external ACPI_OBJECT.) Provides 1986 1.1 jruoho MS compatibility. Lin Ming, Bob Moore. Linux BZ 11105 1987 1.1 jruoho 1988 1.1 jruoho x2APIC support: changes for MADT and SRAT ACPI tables. There are 2 new 1989 1.1 jruoho subtables for the MADT and one new subtable for the SRAT. Includes 1990 1.1 jruoho disassembler and AcpiSrc support. Data from the Intel 64 Architecture x2APIC 1991 1.1 jruoho Specification, June 2008. 1992 1.1 jruoho 1993 1.1 jruoho Additional error checking for pathname utilities. Add error check after all 1994 1.1 jruoho calls to AcpiNsGetPathnameLength. Add status return from 1995 1.1 jruoho AcpiNsBuildExternalPath and check after all calls. Add parameter validation 1996 1.1 jruoho to AcpiUtInitializeBuffer. Reported by and initial patch by Ingo Molnar. 1997 1.1 jruoho 1998 1.1 jruoho Return status from the global init function AcpiUtGlobalInitialize. This is 1999 1.1 jruoho used by both the kernel subsystem and the utilities such as iASL compiler. 2000 1.1 jruoho The function could possibly fail when the caches are initialized. Yang Yi. 2001 1.1 jruoho 2002 1.1 jruoho Add a function to decode reference object types to strings. Created for 2003 1.1 jruoho improved error messages. 2004 1.1 jruoho 2005 1.1.1.2 jruoho Improve object conversion error messages. Better error messages during 2006 1.1.1.2 jruoho object 2007 1.1.1.2 jruoho conversion from internal to the external ACPI_OBJECT. Used for external 2008 1.1.1.2 jruoho calls 2009 1.1 jruoho to AcpiEvaluateObject. 2010 1.1 jruoho 2011 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2012 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2013 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 2014 1.1.1.2 jruoho a 2015 1.1 jruoho much larger code and data size. 2016 1.1 jruoho 2017 1.1 jruoho Previous Release: 2018 1.1 jruoho Non-Debug Version: 79.6K Code, 16.2K Data, 95.8K Total 2019 1.1 jruoho Debug Version: 153.5K Code, 48.2K Data, 201.7K Total 2020 1.1 jruoho Current Release: 2021 1.1 jruoho Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total 2022 1.1 jruoho Debug Version: 153.9K Code, 48.4K Data, 202.3K Total 2023 1.1 jruoho 2024 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2025 1.1 jruoho 2026 1.1 jruoho Debugger: fix a possible hang when evaluating non-methods. Fixes a problem 2027 1.1 jruoho introduced in version 20080701. If the object being evaluated (via execute 2028 1.1 jruoho command) is not a method, the debugger can hang while trying to obtain non- 2029 1.1 jruoho existent parameters. 2030 1.1 jruoho 2031 1.1 jruoho iASL: relax error for using reserved "_T_x" identifiers. These names can 2032 1.1 jruoho appear in a disassembled ASL file if they were emitted by the original 2033 1.1 jruoho compiler. Instead of issuing an error or warning and forcing the user to 2034 1.1 jruoho manually change these names, issue a remark instead. 2035 1.1 jruoho 2036 1.1.1.2 jruoho iASL: error if named object created in while loop. Emit an error if any 2037 1.1.1.2 jruoho named 2038 1.1 jruoho object is created within a While loop. If allowed, this code will generate a 2039 1.1.1.2 jruoho run-time error on the second iteration of the loop when an attempt is made 2040 1.1.1.2 jruoho to 2041 1.1 jruoho create the same named object twice. ACPICA bugzilla 730. 2042 1.1 jruoho 2043 1.1 jruoho iASL: Support absolute pathnames for include files. Add support for absolute 2044 1.1 jruoho pathnames within the Include operator. previously, only relative pathnames 2045 1.1 jruoho were supported. 2046 1.1 jruoho 2047 1.1.1.2 jruoho iASL: Enforce minimum 1 interrupt in interrupt macro and Resource 2048 1.1.1.2 jruoho Descriptor. 2049 1.1 jruoho The ACPI spec requires one interrupt minimum. BZ 423 2050 1.1 jruoho 2051 1.1 jruoho iASL: Handle a missing ResourceSource arg, with a present SourceIndex. 2052 1.1 jruoho Handles the case for the Interrupt Resource Descriptor where 2053 1.1 jruoho the ResourceSource argument is omitted but ResourceSourceIndex 2054 1.1 jruoho is present. Now leave room for the Index. BZ 426 2055 1.1 jruoho 2056 1.1 jruoho iASL: Prevent error message if CondRefOf target does not exist. Fixes cases 2057 1.1 jruoho where an error message is emitted if the target does not exist. BZ 516 2058 1.1 jruoho 2059 1.1 jruoho iASL: Fix broken -g option (get Windows ACPI tables). Fixes the -g option 2060 1.1.1.2 jruoho (get ACPI tables on Windows). This was apparently broken in version 2061 1.1.1.2 jruoho 20070919. 2062 1.1 jruoho 2063 1.1.1.2 jruoho AcpiXtract: Handle EOF while extracting data. Correctly handle the case 2064 1.1.1.2 jruoho where 2065 1.1 jruoho the EOF happens immediately after the last table in the input file. Print 2066 1.1 jruoho completion message. Previously, no message was displayed in this case. 2067 1.1 jruoho 2068 1.1 jruoho ---------------------------------------- 2069 1.1 jruoho 01 July 2008. Summary of changes for version 20080701: 2070 1.1 jruoho 2071 1.1 jruoho 0) Git source tree / acpica.org 2072 1.1 jruoho 2073 1.1 jruoho Fixed a problem where a git-clone from http would not transfer the entire 2074 1.1 jruoho source tree. 2075 1.1 jruoho 2076 1.1 jruoho 1) ACPI CA Core Subsystem: 2077 1.1 jruoho 2078 1.1 jruoho Implemented a "careful" GPE disable in AcpiEvDisableGpe, only modify one 2079 1.1 jruoho enable bit. Now performs a read-change-write of the enable register instead 2080 1.1 jruoho of simply writing out the cached enable mask. This will prevent inadvertent 2081 1.1.1.2 jruoho enabling of GPEs if a rogue GPE is received during initialization (before 2082 1.1.1.2 jruoho GPE 2083 1.1 jruoho handlers are installed.) 2084 1.1 jruoho 2085 1.1 jruoho Implemented a copy for dynamically loaded tables. Previously, dynamically 2086 1.1 jruoho loaded tables were simply mapped - but on some machines this memory is 2087 1.1 jruoho corrupted after suspend. Now copy the table to a local buffer. For the 2088 1.1 jruoho OpRegion case, added checksum verify. Use the table length from the table 2089 1.1 jruoho header, not the region length. For the Buffer case, use the table length 2090 1.1 jruoho also. Dennis Noordsij, Bob Moore. BZ 10734 2091 1.1 jruoho 2092 1.1.1.2 jruoho Fixed a problem where the same ACPI table could not be dynamically loaded 2093 1.1.1.2 jruoho and 2094 1.1 jruoho unloaded more than once. Without this change, a table cannot be loaded again 2095 1.1 jruoho once it has been loaded/unloaded one time. The current mechanism does not 2096 1.1.1.2 jruoho unregister a table upon an unload. During a load, if the same table is 2097 1.1.1.2 jruoho found, 2098 1.1 jruoho this no longer returns an exception. BZ 722 2099 1.1 jruoho 2100 1.1 jruoho Fixed a problem where the wrong descriptor length was calculated for the 2101 1.1 jruoho EndTag descriptor in 64-bit mode. The "minimal" descriptors such as EndTag 2102 1.1 jruoho are calculated as 12 bytes long, but the actual length in the internal 2103 1.1 jruoho descriptor is 16 because of the round-up to 8 on the 64-bit build. Reported 2104 1.1 jruoho by Linn Crosetto. BZ 728 2105 1.1 jruoho 2106 1.1 jruoho Fixed a possible memory leak in the Unload operator. The DdbHandle returned 2107 1.1.1.2 jruoho by Load() did not have its reference count decremented during unload, 2108 1.1.1.2 jruoho leading 2109 1.1 jruoho to a memory leak. Lin Ming. BZ 727 2110 1.1 jruoho 2111 1.1 jruoho Fixed a possible memory leak when deleting thermal/processor objects. Any 2112 1.1 jruoho associated notify handlers (and objects) were not being deleted. Fiodor 2113 1.1 jruoho Suietov. BZ 506 2114 1.1 jruoho 2115 1.1 jruoho Fixed the ordering of the ASCII names in the global mutex table to match the 2116 1.1.1.2 jruoho actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug 2117 1.1.1.2 jruoho only. 2118 1.1 jruoho Vegard Nossum. BZ 726 2119 1.1 jruoho 2120 1.1 jruoho Enhanced the AcpiGetObjectInfo interface to return the number of required 2121 1.1 jruoho arguments if the object is a control method. Added this call to the debugger 2122 1.1 jruoho so the proper number of default arguments are passed to a method. This 2123 1.1 jruoho prevents a warning when executing methods from AcpiExec. 2124 1.1 jruoho 2125 1.1 jruoho Added a check for an invalid handle in AcpiGetObjectInfo. Return 2126 1.1 jruoho AE_BAD_PARAMETER if input handle is invalid. BZ 474 2127 1.1 jruoho 2128 1.1 jruoho Fixed an extraneous warning from exconfig.c on the 64-bit build. 2129 1.1 jruoho 2130 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2131 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2132 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 2133 1.1.1.2 jruoho a 2134 1.1 jruoho much larger code and data size. 2135 1.1 jruoho 2136 1.1 jruoho Previous Release: 2137 1.1 jruoho Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total 2138 1.1 jruoho Debug Version: 153.0K Code, 48.2K Data, 201.2K Total 2139 1.1 jruoho Current Release: 2140 1.1 jruoho Non-Debug Version: 79.6K Code, 16.2K Data, 95.8K Total 2141 1.1 jruoho Debug Version: 153.5K Code, 48.2K Data, 201.7K Total 2142 1.1 jruoho 2143 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2144 1.1 jruoho 2145 1.1 jruoho iASL: Added two missing ACPI reserved names. Added _MTP and _ASZ, both 2146 1.1 jruoho resource descriptor names. 2147 1.1 jruoho 2148 1.1.1.2 jruoho iASL: Detect invalid ASCII characters in input (windows version). Removed 2149 1.1.1.2 jruoho the 2150 1.1 jruoho "-CF" flag from the flex compile, enables correct detection of non-ASCII 2151 1.1 jruoho characters in the input. BZ 441 2152 1.1 jruoho 2153 1.1 jruoho iASL: Eliminate warning when result of LoadTable is not used. Eliminate the 2154 1.1 jruoho "result of operation not used" warning when the DDB handle returned from 2155 1.1 jruoho LoadTable is not used. The warning is not needed. BZ 590 2156 1.1 jruoho 2157 1.1.1.2 jruoho AcpiExec: Add support for dynamic table load/unload. Now calls _CFG method 2158 1.1.1.2 jruoho to 2159 1.1.1.2 jruoho pass address of table to the AML. Added option to disable OpRegion 2160 1.1.1.2 jruoho simulation 2161 1.1.1.2 jruoho to allow creation of an OpRegion with a real address that was passed to 2162 1.1.1.2 jruoho _CFG. 2163 1.1 jruoho All of this allows testing of the Load and Unload operators from AcpiExec. 2164 1.1 jruoho 2165 1.1 jruoho Debugger: update tables command for unloaded tables. Handle unloaded tables 2166 1.1 jruoho and use the standard table header output routine. 2167 1.1 jruoho 2168 1.1 jruoho ---------------------------------------- 2169 1.1 jruoho 09 June 2008. Summary of changes for version 20080609: 2170 1.1 jruoho 2171 1.1 jruoho 1) ACPI CA Core Subsystem: 2172 1.1 jruoho 2173 1.1 jruoho Implemented a workaround for reversed _PRT entries. A significant number of 2174 1.1 jruoho BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This 2175 1.1 jruoho change dynamically detects and repairs this problem. Provides compatibility 2176 1.1 jruoho with MS ACPI. BZ 6859 2177 1.1 jruoho 2178 1.1 jruoho Simplified the internal ACPI hardware interfaces to eliminate the locking 2179 1.1 jruoho flag parameter from Register Read/Write. Added a new external interface, 2180 1.1 jruoho AcpiGetRegisterUnlocked. 2181 1.1 jruoho 2182 1.1.1.2 jruoho Fixed a problem where the invocation of a GPE control method could hang. 2183 1.1.1.2 jruoho This 2184 1.1 jruoho was a regression introduced in 20080514. The new method argument count 2185 1.1 jruoho validation mechanism can enter an infinite loop when a GPE method is 2186 1.1.1.2 jruoho dispatched. Problem fixed by removing the obsolete code that passed GPE 2187 1.1.1.2 jruoho block 2188 1.1 jruoho information to the notify handler via the control method parameter pointer. 2189 1.1 jruoho 2190 1.1 jruoho Fixed a problem where the _SST execution status was incorrectly returned to 2191 1.1 jruoho the caller of AcpiEnterSleepStatePrep. This was a regression introduced in 2192 1.1 jruoho 20080514. _SST is optional and a NOT_FOUND exception should never be 2193 1.1 jruoho returned. BZ 716 2194 1.1 jruoho 2195 1.1 jruoho Fixed a problem where a deleted object could be accessed from within the AML 2196 1.1.1.2 jruoho parser. This was a regression introduced in version 20080123 as a fix for 2197 1.1.1.2 jruoho the 2198 1.1 jruoho Unload operator. Lin Ming. BZ 10669 2199 1.1 jruoho 2200 1.1 jruoho Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands 2201 1.1 jruoho and eliminated the use of a negative index in a loop. Operands are now 2202 1.1 jruoho displayed in the correct order, not backwards. This also fixes a regression 2203 1.1 jruoho introduced in 20080514 on 64-bit systems where the elimination of 2204 1.1 jruoho ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715 2205 1.1 jruoho 2206 1.1 jruoho Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit 2207 1.1 jruoho path did not delete a locally allocated structure. 2208 1.1 jruoho 2209 1.1 jruoho Updated definitions for the DMAR and SRAT tables to synchronize with the 2210 1.1 jruoho current specifications. Includes disassembler support. 2211 1.1 jruoho 2212 1.1 jruoho Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect 2213 1.1 jruoho loop termination value was used. Loop terminated on iteration early, missing 2214 1.1 jruoho one mutex. Linn Crosetto 2215 1.1 jruoho 2216 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2217 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2218 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 2219 1.1.1.2 jruoho a 2220 1.1 jruoho much larger code and data size. 2221 1.1 jruoho 2222 1.1 jruoho Previous Release: 2223 1.1 jruoho Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total 2224 1.1 jruoho Debug Version: 153.3K Code, 48.3K Data, 201.6K Total 2225 1.1 jruoho Current Release: 2226 1.1 jruoho Non-Debug Version: 79.3K Code, 16.2K Data, 95.5K Total 2227 1.1 jruoho Debug Version: 153.0K Code, 48.2K Data, 201.2K Total 2228 1.1 jruoho 2229 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2230 1.1 jruoho 2231 1.1 jruoho Disassembler: Implemented support for EisaId() within _CID objects. Now 2232 1.1 jruoho disassemble integer _CID objects back to EisaId invocations, including 2233 1.1 jruoho multiple integers within _CID packages. Includes single-step support for 2234 1.1 jruoho debugger also. 2235 1.1 jruoho 2236 1.1 jruoho Disassembler: Added support for DMAR and SRAT table definition changes. 2237 1.1 jruoho 2238 1.1 jruoho ---------------------------------------- 2239 1.1 jruoho 14 May 2008. Summary of changes for version 20080514: 2240 1.1 jruoho 2241 1.1 jruoho 1) ACPI CA Core Subsystem: 2242 1.1 jruoho 2243 1.1 jruoho Fixed a problem where GPEs were enabled too early during the ACPICA 2244 1.1 jruoho initialization. This could lead to "handler not installed" errors on some 2245 1.1 jruoho machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This 2246 1.1 jruoho ensures that all operation regions and devices throughout the namespace have 2247 1.1 jruoho been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916. 2248 1.1 jruoho 2249 1.1 jruoho Implemented a change to the enter sleep code. Moved execution of the _GTS 2250 1.1 jruoho method to just before setting sleep enable bit. The execution was moved from 2251 1.1 jruoho AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed 2252 1.1 jruoho immediately before the SLP_EN bit is set, as per the ACPI specification. 2253 1.1 jruoho Luming Yu, BZ 1653. 2254 1.1 jruoho 2255 1.1 jruoho Implemented a fix to disable unknown GPEs (2nd version). Now always disable 2256 1.1 jruoho the GPE, even if ACPICA thinks that that it is already disabled. It is 2257 1.1 jruoho possible that the AML or some other code has enabled the GPE unbeknownst to 2258 1.1 jruoho the ACPICA code. 2259 1.1 jruoho 2260 1.1.1.2 jruoho Fixed a problem with the Field operator where zero-length fields would 2261 1.1.1.2 jruoho return 2262 1.1.1.2 jruoho an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length 2263 1.1.1.2 jruoho ASL 2264 1.1 jruoho field declarations in Field(), BankField(), and IndexField(). BZ 10606. 2265 1.1 jruoho 2266 1.1 jruoho Implemented a fix for the Load operator, now load the table at the namespace 2267 1.1 jruoho root. This reverts a change introduced in version 20071019. The table is now 2268 1.1 jruoho loaded at the namespace root even though this goes against the ACPI 2269 1.1 jruoho specification. This provides compatibility with other ACPI implementations. 2270 1.1.1.2 jruoho The ACPI specification will be updated to reflect this in ACPI 4.0. Lin 2271 1.1.1.2 jruoho Ming. 2272 1.1 jruoho 2273 1.1.1.2 jruoho Fixed a problem where ACPICA would not Load() tables with unusual 2274 1.1.1.2 jruoho signatures. 2275 1.1 jruoho Now ignore ACPI table signature for Load() operator. Only "SSDT" is 2276 1.1 jruoho acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. 2277 1.1.1.2 jruoho Therefore, signature validation is worthless. Apparently MS ACPI accepts 2278 1.1.1.2 jruoho such 2279 1.1 jruoho signatures, ACPICA must be compatible. BZ 10454. 2280 1.1 jruoho 2281 1.1 jruoho Fixed a possible negative array index in AcpiUtValidateException. Added NULL 2282 1.1 jruoho fields to the exception string arrays to eliminate a -1 subtraction on the 2283 1.1 jruoho SubStatus field. 2284 1.1 jruoho 2285 1.1 jruoho Updated the debug tracking macros to reduce overall code and data size. 2286 1.1 jruoho Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings 2287 1.1 jruoho instead of pointers to static strings. Jan Beulich and Bob Moore. 2288 1.1 jruoho 2289 1.1 jruoho Implemented argument count checking in control method invocation via 2290 1.1 jruoho AcpiEvaluateObject. Now emit an error if too few arguments, warning if too 2291 1.1 jruoho many. This applies only to extern programmatic control method execution, not 2292 1.1 jruoho method-to-method calls within the AML. Lin Ming. 2293 1.1 jruoho 2294 1.1 jruoho Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no 2295 1.1.1.2 jruoho longer needed, especially with the removal of 16-bit support. It was 2296 1.1.1.2 jruoho replaced 2297 1.1.1.2 jruoho mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit 2298 1.1.1.2 jruoho on 2299 1.1 jruoho 32/64-bit platforms is required. 2300 1.1 jruoho 2301 1.1 jruoho Added the C const qualifier for appropriate string constants -- mostly 2302 1.1 jruoho MODULE_NAME and printf format strings. Jan Beulich. 2303 1.1 jruoho 2304 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2305 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2306 1.1.1.2 jruoho debug version of the code includes the debug output trace mechanism and has 2307 1.1.1.2 jruoho a 2308 1.1 jruoho much larger code and data size. 2309 1.1 jruoho 2310 1.1 jruoho Previous Release: 2311 1.1 jruoho Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 2312 1.1 jruoho Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 2313 1.1 jruoho Current Release: 2314 1.1 jruoho Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total 2315 1.1 jruoho Debug Version: 153.3K Code, 48.3K Data, 201.6K Total 2316 1.1 jruoho 2317 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2318 1.1 jruoho 2319 1.1 jruoho Implemented ACPI table revision ID validation in the disassembler. Zero is 2320 1.1 jruoho always invalid. For DSDTs, the ID controls the interpreter integer width. 1 2321 1.1 jruoho means 32-bit and this is unusual. 2 or greater is 64-bit. 2322 1.1 jruoho 2323 1.1 jruoho ---------------------------------------- 2324 1.1 jruoho 21 March 2008. Summary of changes for version 20080321: 2325 1.1 jruoho 2326 1.1 jruoho 1) ACPI CA Core Subsystem: 2327 1.1 jruoho 2328 1.1 jruoho Implemented an additional change to the GPE support in order to suppress 2329 1.1 jruoho spurious or stray GPEs. The AcpiEvDisableGpe function will now permanently 2330 1.1 jruoho disable incoming GPEs that are neither enabled nor disabled -- meaning that 2331 1.1.1.2 jruoho the GPE is unknown to the system. This should prevent future interrupt 2332 1.1.1.2 jruoho floods 2333 1.1 jruoho from that GPE. BZ 6217 (Zhang Rui) 2334 1.1 jruoho 2335 1.1 jruoho Fixed a problem where NULL package elements were not returned to the 2336 1.1 jruoho AcpiEvaluateObject interface correctly. The element was simply ignored 2337 1.1 jruoho instead of returning a NULL ACPI_OBJECT package element, potentially causing 2338 1.1 jruoho a buffer overflow and/or confusing the caller who expected a fixed number of 2339 1.1 jruoho elements. BZ 10132 (Lin Ming, Bob Moore) 2340 1.1 jruoho 2341 1.1.1.2 jruoho Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, 2342 1.1.1.2 jruoho Dword, 2343 1.1 jruoho Qword), Field, BankField, and IndexField operators when invoked from inside 2344 1.1 jruoho an executing control method. In this case, these operators created namespace 2345 1.1 jruoho nodes that were incorrectly left marked as permanent nodes instead of 2346 1.1 jruoho temporary nodes. This could cause a problem if there is race condition 2347 1.1 jruoho between an exiting control method and a running namespace walk. (Reported by 2348 1.1 jruoho Linn Crosetto) 2349 1.1 jruoho 2350 1.1 jruoho Fixed a problem where the CreateField and CreateXXXField operators would 2351 1.1 jruoho incorrectly allow duplicate names (the name of the field) with no exception 2352 1.1 jruoho generated. 2353 1.1 jruoho 2354 1.1.1.2 jruoho Implemented several changes for Notify handling. Added support for new 2355 1.1.1.2 jruoho Notify 2356 1.1 jruoho values (ACPI 2.0+) and improved the Notify debug output. Notify on 2357 1.1 jruoho PowerResource objects is no longer allowed, as per the ACPI specification. 2358 1.1 jruoho (Bob Moore, Zhang Rui) 2359 1.1 jruoho 2360 1.1 jruoho All Reference Objects returned via the AcpiEvaluateObject interface are now 2361 1.1.1.2 jruoho marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved 2362 1.1.1.2 jruoho for 2363 1.1 jruoho NULL objects - either NULL package elements or unresolved named references. 2364 1.1 jruoho 2365 1.1 jruoho Fixed a problem where an extraneous debug message was produced for package 2366 1.1 jruoho objects (when debugging enabled). The message "Package List length larger 2367 1.1 jruoho than NumElements count" is now produced in the correct case, and is now an 2368 1.1 jruoho error message rather than a debug message. Added a debug message for the 2369 1.1.1.2 jruoho opposite case, where NumElements is larger than the Package List (the 2370 1.1.1.2 jruoho package 2371 1.1 jruoho will be padded out with NULL elements as per the ACPI spec.) 2372 1.1 jruoho 2373 1.1 jruoho Implemented several improvements for the output of the ASL "Debug" object to 2374 1.1 jruoho clarify and keep all data for a given object on one output line. 2375 1.1 jruoho 2376 1.1 jruoho Fixed two size calculation issues with the variable-length Start Dependent 2377 1.1 jruoho resource descriptor. 2378 1.1 jruoho 2379 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2380 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2381 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2382 1.1 jruoho a much larger code and data size. 2383 1.1 jruoho 2384 1.1 jruoho Previous Release: 2385 1.1 jruoho Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total 2386 1.1 jruoho Debug Version: 158.9K Code, 64.0K Data, 222.9K Total 2387 1.1 jruoho Current Release: 2388 1.1 jruoho Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 2389 1.1 jruoho Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 2390 1.1 jruoho 2391 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2392 1.1 jruoho 2393 1.1 jruoho Fixed a problem with the use of the Switch operator where execution of the 2394 1.1 jruoho containing method by multiple concurrent threads could cause an 2395 1.1 jruoho AE_ALREADY_EXISTS exception. This is caused by the fact that there is no 2396 1.1 jruoho actual Switch opcode, it must be simulated with local named temporary 2397 1.1 jruoho variables and if/else pairs. The solution chosen was to mark any method that 2398 1.1 jruoho uses Switch as Serialized, thus preventing multiple thread entries. BZ 469. 2399 1.1 jruoho 2400 1.1 jruoho ---------------------------------------- 2401 1.1 jruoho 13 February 2008. Summary of changes for version 20080213: 2402 1.1 jruoho 2403 1.1 jruoho 1) ACPI CA Core Subsystem: 2404 1.1 jruoho 2405 1.1 jruoho Implemented another MS compatibility design change for GPE/Notify handling. 2406 1.1 jruoho GPEs are now cleared/enabled asynchronously to allow all pending notifies to 2407 1.1 jruoho complete first. It is expected that the OSL will queue the enable request 2408 1.1.1.2 jruoho behind all pending notify requests (may require changes to the local host 2409 1.1.1.2 jruoho OSL 2410 1.1 jruoho in AcpiOsExecute). Alexey Starikovskiy. 2411 1.1 jruoho 2412 1.1 jruoho Fixed a problem where buffer and package objects passed as arguments to a 2413 1.1 jruoho control method via the external AcpiEvaluateObject interface could cause an 2414 1.1 jruoho AE_AML_INTERNAL exception depending on the order and type of operators 2415 1.1 jruoho executed by the target control method. 2416 1.1 jruoho 2417 1.1 jruoho Fixed a problem where resource descriptor size optimization could cause a 2418 1.1 jruoho problem when a _CRS resource template is passed to a _SRS method. The _SRS 2419 1.1 jruoho resource template must use the same descriptors (with the same size) as 2420 1.1 jruoho returned from _CRS. This change affects the following resource descriptors: 2421 1.1 jruoho IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 9487) 2422 1.1 jruoho 2423 1.1 jruoho Fixed a problem where a CopyObject to RegionField, BankField, and IndexField 2424 1.1.1.2 jruoho objects did not perform an implicit conversion as it should. These types 2425 1.1.1.2 jruoho must 2426 1.1.1.2 jruoho retain their initial type permanently as per the ACPI specification. 2427 1.1.1.2 jruoho However, 2428 1.1 jruoho a CopyObject to all other object types should not perform an implicit 2429 1.1 jruoho conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388 2430 1.1 jruoho 2431 1.1 jruoho Fixed a problem with the AcpiGetDevices interface where the mechanism to 2432 1.1 jruoho match device CIDs did not examine the entire list of available CIDs, but 2433 1.1 jruoho instead aborted on the first non-matching CID. Andrew Patterson. 2434 1.1 jruoho 2435 1.1.1.2 jruoho Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro 2436 1.1.1.2 jruoho was 2437 1.1 jruoho inadvertently changed to return a 16-bit value instead of a 32-bit value, 2438 1.1 jruoho truncating the upper dword of a 64-bit value. This macro is only used to 2439 1.1 jruoho display debug output, so no incorrect calculations were made. Also, 2440 1.1 jruoho reimplemented the macro so that a 64-bit shift is not performed by 2441 1.1 jruoho inefficient compilers. 2442 1.1 jruoho 2443 1.1 jruoho Added missing va_end statements that should correspond with each va_start 2444 1.1 jruoho statement. 2445 1.1 jruoho 2446 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2447 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2448 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2449 1.1 jruoho a much larger code and data size. 2450 1.1 jruoho 2451 1.1 jruoho Previous Release: 2452 1.1 jruoho Non-Debug Version: 79.5K Code, 17.2K Data, 96.7K Total 2453 1.1 jruoho Debug Version: 159.0K Code, 63.8K Data, 222.8K Total 2454 1.1 jruoho Current Release: 2455 1.1 jruoho Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total 2456 1.1 jruoho Debug Version: 158.9K Code, 64.0K Data, 222.9K Total 2457 1.1 jruoho 2458 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2459 1.1 jruoho 2460 1.1 jruoho Implemented full disassembler support for the following new ACPI tables: 2461 1.1 jruoho BERT, EINJ, and ERST. Implemented partial disassembler support for the 2462 1.1 jruoho complicated HEST table. These tables support the Windows Hardware Error 2463 1.1 jruoho Architecture (WHEA). 2464 1.1 jruoho 2465 1.1 jruoho ---------------------------------------- 2466 1.1 jruoho 23 January 2008. Summary of changes for version 20080123: 2467 1.1 jruoho 2468 1.1 jruoho 1) ACPI CA Core Subsystem: 2469 1.1 jruoho 2470 1.1 jruoho Added the 2008 copyright to all module headers and signons. This affects 2471 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, and 2472 1.1 jruoho the tools/utilities. 2473 1.1 jruoho 2474 1.1 jruoho Fixed a problem with the SizeOf operator when used with Package and Buffer 2475 1.1 jruoho objects. These objects have deferred execution for some arguments, and the 2476 1.1.1.2 jruoho execution is now completed before the SizeOf is executed. This problem 2477 1.1.1.2 jruoho caused 2478 1.1 jruoho unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) BZ 2479 1.1 jruoho 9558 2480 1.1 jruoho 2481 1.1.1.2 jruoho Implemented an enhancement to the interpreter "slack mode". In the absence 2482 1.1.1.2 jruoho of 2483 1.1 jruoho an explicit return or an implicitly returned object from the last executed 2484 1.1.1.2 jruoho opcode, a control method will now implicitly return an integer of value 0 2485 1.1.1.2 jruoho for 2486 1.1 jruoho Microsoft compatibility. (Lin Ming) BZ 392 2487 1.1 jruoho 2488 1.1.1.2 jruoho Fixed a problem with the Load operator where an exception was not returned 2489 1.1.1.2 jruoho in 2490 1.1 jruoho the case where the table is already loaded. (Lin Ming) BZ 463 2491 1.1 jruoho 2492 1.1.1.2 jruoho Implemented support for the use of DDBHandles as an Indexed Reference, as 2493 1.1.1.2 jruoho per 2494 1.1 jruoho the ACPI spec. (Lin Ming) BZ 486 2495 1.1 jruoho 2496 1.1 jruoho Implemented support for UserTerm (Method invocation) for the Unload operator 2497 1.1 jruoho as per the ACPI spec. (Lin Ming) BZ 580 2498 1.1 jruoho 2499 1.1 jruoho Fixed a problem with the LoadTable operator where the OemId and OemTableId 2500 1.1 jruoho input strings could cause unexpected failures if they were shorter than the 2501 1.1 jruoho maximum lengths allowed. (Lin Ming, Bob Moore) BZ 576 2502 1.1 jruoho 2503 1.1 jruoho Implemented support for UserTerm (Method invocation) for the Unload operator 2504 1.1 jruoho as per the ACPI spec. (Lin Ming) BZ 580 2505 1.1 jruoho 2506 1.1.1.2 jruoho Implemented header file support for new ACPI tables - BERT, ERST, EINJ, 2507 1.1.1.2 jruoho HEST, 2508 1.1 jruoho IBFT, UEFI, WDAT. Disassembler support is forthcoming. 2509 1.1 jruoho 2510 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2511 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2512 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2513 1.1 jruoho a much larger code and data size. 2514 1.1 jruoho 2515 1.1 jruoho Previous Release: 2516 1.1 jruoho Non-Debug Version: 79.3K Code, 17.2K Data, 96.5K Total 2517 1.1 jruoho Debug Version: 158.6K Code, 63.8K Data, 222.4K Total 2518 1.1 jruoho Current Release: 2519 1.1 jruoho Non-Debug Version: 79.5K Code, 17.2K Data, 96.7K Total 2520 1.1 jruoho Debug Version: 159.0K Code, 63.8K Data, 222.8K Total 2521 1.1 jruoho 2522 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2523 1.1 jruoho 2524 1.1 jruoho Implemented support in the disassembler for checksum validation on incoming 2525 1.1.1.2 jruoho binary DSDTs and SSDTs. If incorrect, a message is displayed within the 2526 1.1.1.2 jruoho table 2527 1.1 jruoho header dump at the start of the disassembly. 2528 1.1 jruoho 2529 1.1 jruoho Implemented additional debugging information in the namespace listing file 2530 1.1 jruoho created during compilation. In addition to the namespace hierarchy, the full 2531 1.1 jruoho pathname to each namespace object is displayed. 2532 1.1 jruoho 2533 1.1 jruoho Fixed a problem with the disassembler where invalid ACPI tables could cause 2534 1.1 jruoho faults or infinite loops. 2535 1.1 jruoho 2536 1.1 jruoho Fixed an unexpected parse error when using the optional "parameter types" 2537 1.1 jruoho list in a control method declaration. (Lin Ming) BZ 397 2538 1.1 jruoho 2539 1.1 jruoho Fixed a problem where two External declarations with the same name did not 2540 1.1 jruoho cause an error (Lin Ming) BZ 509 2541 1.1 jruoho 2542 1.1 jruoho Implemented support for full TermArgs (adding Argx, Localx and method 2543 1.1 jruoho invocation) for the ParameterData parameter to the LoadTable operator.

Summary of changes for version 20071219: 2548 1.1 jruoho 2549 1.1 jruoho 1) ACPI CA Core Subsystem: 2550 1.1 jruoho 2551 1.1 jruoho Implemented full support for deferred execution for the TermArg string 2552 1.1 jruoho arguments for DataTableRegion. This enables forward references and full 2553 1.1.1.2 jruoho operand resolution for the three string arguments. Similar to 2554 1.1.1.2 jruoho OperationRegion 2555 1.1 jruoho deferred argument execution.) Lin Ming. BZ 430 2556 1.1 jruoho 2557 1.1 jruoho Implemented full argument resolution support for the BankValue argument to 2558 1.1 jruoho BankField. Previously, only constants were supported, now any TermArg may be 2559 1.1 jruoho used. Lin Ming BZ 387, 393 2560 1.1 jruoho 2561 1.1 jruoho Fixed a problem with AcpiGetDevices where the search of a branch of the 2562 1.1 jruoho device tree could be terminated prematurely. In accordance with the ACPI 2563 1.1 jruoho specification, the search down the current branch is terminated if a device 2564 1.1 jruoho is both not present and not functional (instead of just not present.) Yakui 2565 1.1 jruoho Zhao. 2566 1.1 jruoho 2567 1.1 jruoho Fixed a problem where "unknown" GPEs could be allowed to fire repeatedly if 2568 1.1 jruoho the underlying AML code changed the GPE enable registers. Now, any unknown 2569 1.1.1.2 jruoho incoming GPE (no _Lxx/_Exx method and not the EC GPE) is immediately 2570 1.1.1.2 jruoho disabled 2571 1.1 jruoho instead of simply ignored. Rui Zhang. 2572 1.1 jruoho 2573 1.1 jruoho Fixed a problem with Index Fields where the Index register was incorrectly 2574 1.1 jruoho limited to a maximum of 32 bits. Now any size may be used. 2575 1.1 jruoho 2576 1.1 jruoho Fixed a couple memory leaks associated with "implicit return" objects when 2577 1.1 jruoho the AML Interpreter slack mode is enabled. Lin Ming BZ 349 2578 1.1 jruoho 2579 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2580 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2581 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2582 1.1 jruoho a much larger code and data size. 2583 1.1 jruoho 2584 1.1 jruoho Previous Release: 2585 1.1 jruoho Non-Debug Version: 79.0K Code, 17.2K Data, 96.2K Total 2586 1.1 jruoho Debug Version: 157.9K Code, 63.6K Data, 221.5K Total 2587 1.1 jruoho Current Release: 2588 1.1 jruoho Non-Debug Version: 79.3K Code, 17.2K Data, 96.5K Total 2589 1.1 jruoho Debug Version: 158.6K Code, 63.8K Data, 222.4K Total 2590 1.1 jruoho 2591 1.1 jruoho ---------------------------------------- 2592 1.1 jruoho 14 November 2007. Summary of changes for version 20071114: 2593 1.1 jruoho 2594 1.1 jruoho 1) ACPI CA Core Subsystem: 2595 1.1 jruoho 2596 1.1 jruoho Implemented event counters for each of the Fixed Events, the ACPI SCI 2597 1.1 jruoho (interrupt) itself, and control methods executed. Named 2598 1.1 jruoho AcpiFixedEventCount[], AcpiSciCount, and AcpiMethodCount respectively. These 2599 1.1 jruoho should be useful for debugging and statistics. 2600 1.1 jruoho 2601 1.1 jruoho Implemented a new external interface, AcpiGetStatistics, to retrieve the 2602 1.1 jruoho contents of the various event counters. Returns the current values for 2603 1.1 jruoho AcpiSciCount, AcpiGpeCount, the AcpiFixedEventCount array, and 2604 1.1 jruoho AcpiMethodCount. The interface can be expanded in the future if new counters 2605 1.1 jruoho are added. Device drivers should use this interface rather than access the 2606 1.1 jruoho counters directly. 2607 1.1 jruoho 2608 1.1 jruoho Fixed a problem with the FromBCD and ToBCD operators. With some compilers, 2609 1.1 jruoho the ShortDivide function worked incorrectly, causing problems with the BCD 2610 1.1 jruoho functions with large input values. A truncation from 64-bit to 32-bit 2611 1.1 jruoho inadvertently occurred. Internal BZ 435. Lin Ming 2612 1.1 jruoho 2613 1.1 jruoho Fixed a problem with Index references passed as method arguments. References 2614 1.1 jruoho passed as arguments to control methods were dereferenced immediately (before 2615 1.1 jruoho control was passed to the called method). The references are now correctly 2616 1.1 jruoho passed directly to the called method. BZ 5389. Lin Ming 2617 1.1 jruoho 2618 1.1 jruoho Fixed a problem with CopyObject used in conjunction with the Index operator. 2619 1.1 jruoho The reference was incorrectly dereferenced before the copy. The reference is 2620 1.1 jruoho now correctly copied. BZ 5391. Lin Ming 2621 1.1 jruoho 2622 1.1 jruoho Fixed a problem with Control Method references within Package objects. These 2623 1.1 jruoho references are now correctly generated. This completes the package 2624 1.1 jruoho construction overhaul that began in version 20071019. 2625 1.1 jruoho 2626 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2627 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2628 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2629 1.1 jruoho a much larger code and data size. 2630 1.1 jruoho 2631 1.1 jruoho Previous Release: 2632 1.1 jruoho Non-Debug Version: 78.8K Code, 17.2K Data, 96.0K Total 2633 1.1 jruoho Debug Version: 157.2K Code, 63.4K Data, 220.6K Total 2634 1.1 jruoho Current Release: 2635 1.1 jruoho Non-Debug Version: 79.0K Code, 17.2K Data, 96.2K Total 2636 1.1 jruoho Debug Version: 157.9K Code, 63.6K Data, 221.5K Total 2637 1.1 jruoho 2638 1.1 jruoho 2639 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2640 1.1 jruoho 2641 1.1 jruoho The AcpiExec utility now installs handlers for all of the predefined 2642 1.1 jruoho Operation Region types. New types supported are: PCI_Config, CMOS, and 2643 1.1 jruoho PCIBARTarget. 2644 1.1 jruoho 2645 1.1 jruoho Fixed a problem with the 64-bit version of AcpiExec where the extended (64- 2646 1.1 jruoho bit) address fields for the DSDT and FACS within the FADT were not being 2647 1.1 jruoho used, causing truncation of the upper 32-bits of these addresses. Lin Ming 2648 1.1 jruoho and Bob Moore 2649 1.1 jruoho 2650 1.1 jruoho ---------------------------------------- 2651 1.1 jruoho 19 October 2007. Summary of changes for version 20071019: 2652 1.1 jruoho 2653 1.1 jruoho 1) ACPI CA Core Subsystem: 2654 1.1 jruoho 2655 1.1 jruoho Fixed a problem with the Alias operator when the target of the alias is a 2656 1.1 jruoho named ASL operator that opens a new scope -- Scope, Device, PowerResource, 2657 1.1 jruoho Processor, and ThermalZone. In these cases, any children of the original 2658 1.1 jruoho operator could not be accessed via the alias, potentially causing unexpected 2659 1.1 jruoho AE_NOT_FOUND exceptions. (BZ 9067) 2660 1.1 jruoho 2661 1.1 jruoho Fixed a problem with the Package operator where all named references were 2662 1.1 jruoho created as object references and left otherwise unresolved. According to the 2663 1.1 jruoho ACPI specification, a Package can only contain Data Objects or references to 2664 1.1 jruoho control methods. The implication is that named references to Data Objects 2665 1.1 jruoho (Integer, Buffer, String, Package, BufferField, Field) should be resolved 2666 1.1 jruoho immediately upon package creation. This is the approach taken with this 2667 1.1 jruoho change. References to all other named objects (Methods, Devices, Scopes, 2668 1.1 jruoho etc.) are all now properly created as reference objects. (BZ 5328) 2669 1.1 jruoho 2670 1.1 jruoho Reverted a change to Notify handling that was introduced in version 2671 1.1 jruoho 20070508. This version changed the Notify handling from asynchronous to 2672 1.1 jruoho fully synchronous (Device driver Notify handling with respect to the Notify 2673 1.1 jruoho ASL operator). It was found that this change caused more problems than it 2674 1.1 jruoho solved and was removed by most users. 2675 1.1 jruoho 2676 1.1 jruoho Fixed a problem with the Increment and Decrement operators where the type of 2677 1.1 jruoho the target object could be unexpectedly and incorrectly changed. (BZ 353) 2678 1.1 jruoho Lin Ming. 2679 1.1 jruoho 2680 1.1 jruoho Fixed a problem with the Load and LoadTable operators where the table 2681 1.1 jruoho location within the namespace was ignored. Instead, the table was always 2682 1.1 jruoho loaded into the root or current scope. Lin Ming. 2683 1.1 jruoho 2684 1.1 jruoho Fixed a problem with the Load operator when loading a table from a buffer 2685 1.1 jruoho object. The input buffer was prematurely zeroed and/or deleted. (BZ 577) 2686 1.1 jruoho 2687 1.1 jruoho Fixed a problem with the Debug object where a store of a DdbHandle reference 2688 1.1 jruoho object to the Debug object could cause a fault. 2689 1.1 jruoho 2690 1.1 jruoho Added a table checksum verification for the Load operator, in the case where 2691 1.1 jruoho the load is from a buffer. (BZ 578). 2692 1.1 jruoho 2693 1.1 jruoho Implemented additional parameter validation for the LoadTable operator. The 2694 1.1 jruoho length of the input strings SignatureString, OemIdString, and OemTableId are 2695 1.1 jruoho now checked for maximum lengths. (BZ 582) Lin Ming. 2696 1.1 jruoho 2697 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2698 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2699 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2700 1.1 jruoho a much larger code and data size. 2701 1.1 jruoho 2702 1.1 jruoho Previous Release: 2703 1.1 jruoho Non-Debug Version: 78.5K Code, 17.1K Data, 95.6K Total 2704 1.1 jruoho Debug Version: 156.7K Code, 63.2K Data, 219.9K Total 2705 1.1 jruoho Current Release: 2706 1.1 jruoho Non-Debug Version: 78.8K Code, 17.2K Data, 96.0K Total 2707 1.1 jruoho Debug Version: 157.2K Code, 63.4K Data, 220.6K Total 2708 1.1 jruoho 2709 1.1 jruoho 2710 1.1 jruoho 2) iASL Compiler/Disassembler: 2711 1.1 jruoho 2712 1.1 jruoho Fixed a problem where if a single file was specified and the file did not 2713 1.1 jruoho exist, no error message was emitted. (Introduced with wildcard support in 2714 1.1 jruoho version 20070917.) 2715 1.1 jruoho 2716 1.1 jruoho ---------------------------------------- 2717 1.1 jruoho 19 September 2007. Summary of changes for version 20070919: 2718 1.1 jruoho 2719 1.1 jruoho 1) ACPI CA Core Subsystem: 2720 1.1 jruoho 2721 1.1 jruoho Designed and implemented new external interfaces to install and remove 2722 1.1 jruoho handlers for ACPI table-related events. Current events that are defined are 2723 1.1 jruoho LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as 2724 1.1 jruoho they are dynamically loaded and unloaded. See AcpiInstallTableHandler and 2725 1.1 jruoho AcpiRemoveTableHandler. (Lin Ming and Bob Moore) 2726 1.1 jruoho 2727 1.1 jruoho Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag 2728 1.1 jruoho (acpi_serialized option on Linux) could cause some systems to hang during 2729 1.1 jruoho initialization. (Bob Moore) BZ 8171 2730 1.1 jruoho 2731 1.1 jruoho Fixed a problem where objects of certain types (Device, ThermalZone, 2732 1.1 jruoho Processor, PowerResource) can be not found if they are declared and 2733 1.1 jruoho referenced from within the same control method (Lin Ming) BZ 341 2734 1.1 jruoho 2735 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2736 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2737 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2738 1.1 jruoho a much larger code and data size. 2739 1.1 jruoho 2740 1.1 jruoho Previous Release: 2741 1.1 jruoho Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total 2742 1.1 jruoho Debug Version: 156.3K Code, 63.1K Data, 219.4K Total 2743 1.1 jruoho Current Release: 2744 1.1 jruoho Non-Debug Version: 78.5K Code, 17.1K Data, 95.6K Total 2745 1.1 jruoho Debug Version: 156.7K Code, 63.2K Data, 219.9K Total 2746 1.1 jruoho 2747 1.1 jruoho 2748 1.1 jruoho 2) iASL Compiler/Disassembler: 2749 1.1 jruoho 2750 1.1 jruoho Implemented support to allow multiple files to be compiled/disassembled in a 2751 1.1 jruoho single invocation. This includes command line wildcard support for both the 2752 1.1 jruoho Windows and Unix versions of the compiler. This feature simplifies the 2753 1.1 jruoho disassembly and compilation of multiple ACPI tables in a single directory. 2754 1.1 jruoho 2755 1.1 jruoho ---------------------------------------- 2756 1.1 jruoho 08 May 2007. Summary of changes for version 20070508: 2757 1.1 jruoho 2758 1.1 jruoho 1) ACPI CA Core Subsystem: 2759 1.1 jruoho 2760 1.1 jruoho Implemented a Microsoft compatibility design change for the handling of the 2761 1.1 jruoho Notify AML operator. Previously, notify handlers were dispatched and 2762 1.1 jruoho executed completely asynchronously in a deferred thread. The new design 2763 1.1 jruoho still executes the notify handlers in a different thread, but the original 2764 1.1 jruoho thread that executed the Notify() now waits at a synchronization point for 2765 1.1 jruoho the notify handler to complete. Some machines depend on a synchronous Notify 2766 1.1 jruoho operator in order to operate correctly. 2767 1.1 jruoho 2768 1.1 jruoho Implemented support to allow Package objects to be passed as method 2769 1.1 jruoho arguments to the external AcpiEvaluateObject interface. Previously, this 2770 1.1 jruoho would return the AE_NOT_IMPLEMENTED exception. This feature had not been 2771 1.1 jruoho implemented since there were no reserved control methods that required it 2772 1.1 jruoho until recently. 2773 1.1 jruoho 2774 1.1 jruoho Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that 2775 1.1 jruoho contained invalid non-zero values in reserved fields could cause later 2776 1.1 jruoho failures because these fields have meaning in later revisions of the FADT. 2777 1.1 jruoho For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The fields 2778 1.1 jruoho are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.) 2779 1.1 jruoho 2780 1.1 jruoho Fixed a problem where the Global Lock handle was not properly updated if a 2781 1.1 jruoho thread that acquired the Global Lock via executing AML code then attempted 2782 1.1 jruoho to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by Joe 2783 1.1 jruoho Liu. 2784 1.1 jruoho 2785 1.1 jruoho Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list 2786 1.1 jruoho could be corrupted if the interrupt being removed was at the head of the 2787 1.1 jruoho list. Reported by Linn Crosetto. 2788 1.1 jruoho 2789 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2790 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2791 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2792 1.1 jruoho a much larger code and data size. 2793 1.1 jruoho 2794 1.1 jruoho Previous Release: 2795 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 2796 1.1 jruoho Debug Version: 155.9K Code, 63.1K Data, 219.0K Total 2797 1.1 jruoho Current Release: 2798 1.1 jruoho Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total 2799 1.1 jruoho Debug Version: 156.3K Code, 63.1K Data, 219.4K Total 2800 1.1 jruoho 2801 1.1 jruoho ---------------------------------------- 2802 1.1 jruoho 20 March 2007. Summary of changes for version 20070320: 2803 1.1 jruoho 2804 1.1 jruoho 1) ACPI CA Core Subsystem: 2805 1.1 jruoho 2806 1.1 jruoho Implemented a change to the order of interpretation and evaluation of AML 2807 1.1 jruoho operand objects within the AML interpreter. The interpreter now evaluates 2808 1.1 jruoho operands in the order that they appear in the AML stream (and the 2809 1.1 jruoho corresponding ASL code), instead of in the reverse order (after the entire 2810 1.1 jruoho operand list has been parsed). The previous behavior caused several subtle 2811 1.1 jruoho incompatibilities with the Microsoft AML interpreter as well as being 2812 1.1 jruoho somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov. 2813 1.1 jruoho 2814 1.1 jruoho Implemented a change to the ACPI Global Lock support. All interfaces to the 2815 1.1 jruoho global lock now allow the same thread to acquire the lock multiple times. 2816 1.1 jruoho This affects the AcpiAcquireGlobalLock external interface to the global lock 2817 1.1 jruoho as well as the internal use of the global lock to support AML fields -- a 2818 1.1 jruoho control method that is holding the global lock can now simultaneously access 2819 1.1 jruoho AML fields that require global lock protection. Previously, in both cases, 2820 1.1 jruoho this would have resulted in an AE_ALREADY_ACQUIRED exception. The change to 2821 1.1 jruoho AcpiAcquireGlobalLock is of special interest to drivers for the Embedded 2822 1.1 jruoho Controller. There is no change to the behavior of the AML Acquire operator, 2823 1.1 jruoho as this can already be used to acquire a mutex multiple times by the same 2824 1.1 jruoho thread. BZ 8066. With assistance from Alexey Starikovskiy. 2825 1.1 jruoho 2826 1.1 jruoho Fixed a problem where invalid objects could be referenced in the AML 2827 1.1 jruoho Interpreter after error conditions. During operand evaluation, ensure that 2828 1.1 jruoho the internal "Return Object" field is cleared on error and only valid 2829 1.1 jruoho pointers are stored there. Caused occasional access to deleted objects that 2830 1.1 jruoho resulted in "large reference count" warning messages. Valery Podrezov. 2831 1.1 jruoho 2832 1.1 jruoho Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur on 2833 1.1 jruoho deeply nested control method invocations. BZ 7873, local BZ 487. Valery 2834 1.1 jruoho Podrezov. 2835 1.1 jruoho 2836 1.1 jruoho Fixed an internal problem with the handling of result objects on the 2837 1.1 jruoho interpreter result stack. BZ 7872. Valery Podrezov. 2838 1.1 jruoho 2839 1.1 jruoho Removed obsolete code that handled the case where AML_NAME_OP is the target 2840 1.1 jruoho of a reference (Reference.Opcode). This code was no longer necessary. BZ 2841 1.1 jruoho 7874. Valery Podrezov. 2842 1.1 jruoho 2843 1.1 jruoho Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This was a 2844 1.1 jruoho remnant from the previously discontinued 16-bit support. 2845 1.1 jruoho 2846 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2847 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2848 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2849 1.1 jruoho a much larger code and data size. 2850 1.1 jruoho 2851 1.1 jruoho Previous Release: 2852 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 2853 1.1 jruoho Debug Version: 155.8K Code, 63.3K Data, 219.1K Total 2854 1.1 jruoho Current Release: 2855 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 2856 1.1 jruoho Debug Version: 155.9K Code, 63.1K Data, 219.0K Total 2857 1.1 jruoho 2858 1.1 jruoho ---------------------------------------- 2859 1.1 jruoho 26 January 2007. Summary of changes for version 20070126: 2860 1.1 jruoho 2861 1.1 jruoho 1) ACPI CA Core Subsystem: 2862 1.1 jruoho 2863 1.1 jruoho Added the 2007 copyright to all module headers and signons. This affects 2864 1.1 jruoho virtually every file in the ACPICA core subsystem, the iASL compiler, and 2865 1.1 jruoho the utilities. 2866 1.1 jruoho 2867 1.1 jruoho Implemented a fix for an incorrect parameter passed to AcpiTbDeleteTable 2868 1.1 jruoho during a table load. A bad pointer was passed in the case where the DSDT is 2869 1.1 jruoho overridden, causing a fault in this case. 2870 1.1 jruoho 2871 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2872 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20061215: 2885 1.1 jruoho 2886 1.1 jruoho 1) ACPI CA Core Subsystem: 2887 1.1 jruoho 2888 1.1 jruoho Support for 16-bit ACPICA has been completely removed since it is no longer 2889 1.1 jruoho necessary and it clutters the code. All 16-bit macros, types, and 2890 1.1 jruoho conditional compiles have been removed, cleaning up and simplifying the code 2891 1.1 jruoho across the entire subsystem. DOS support is no longer needed since the 2892 1.1 jruoho bootable Linux firmware kit is now available. 2893 1.1 jruoho 2894 1.1 jruoho The handler for the Global Lock is now removed during AcpiTerminate to 2895 1.1 jruoho enable a clean subsystem restart, via the implementation of the 2896 1.1 jruoho AcpiEvRemoveGlobalLockHandler function. (With assistance from Joel Bretz, 2897 1.1 jruoho HP) 2898 1.1 jruoho 2899 1.1 jruoho Implemented enhancements to the multithreading support within the debugger 2900 1.1 jruoho to enable improved multithreading debugging and evaluation of the subsystem. 2901 1.1 jruoho (Valery Podrezov) 2902 1.1 jruoho 2903 1.1 jruoho Debugger: Enhanced the Statistics/Memory command to emit the total (maximum) 2904 1.1 jruoho memory used during the execution, as well as the maximum memory consumed by 2905 1.1 jruoho each of the various object types. (Valery Podrezov) 2906 1.1 jruoho 2907 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2908 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2909 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2910 1.1 jruoho a much larger code and data size. 2911 1.1 jruoho 2912 1.1 jruoho Previous Release: 2913 1.1 jruoho Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total 2914 1.1 jruoho Debug Version: 155.2K Code, 63.1K Data, 218.3K Total 2915 1.1 jruoho Current Release: 2916 1.1 jruoho Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 2917 1.1 jruoho Debug Version: 155.8K Code, 63.3K Data, 219.1K Total 2918 1.1 jruoho 2919 1.1 jruoho 2920 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2921 1.1 jruoho 2922 1.1 jruoho AcpiExec: Implemented a new option (-m) to display full memory use 2923 1.1 jruoho statistics upon subsystem/program termination. (Valery Podrezov) 2924 1.1 jruoho 2925 1.1 jruoho ---------------------------------------- 2926 1.1 jruoho 09 November 2006. Summary of changes for version 20061109: 2927 1.1 jruoho 2928 1.1 jruoho 1) ACPI CA Core Subsystem: 2929 1.1 jruoho 2930 1.1 jruoho Optimized the Load ASL operator in the case where the source operand is an 2931 1.1 jruoho operation region. Simply map the operation region memory, instead of 2932 1.1 jruoho performing a bytewise read. (Region must be of type SystemMemory, see 2933 1.1 jruoho below.) 2934 1.1 jruoho 2935 1.1 jruoho Fixed the Load ASL operator for the case where the source operand is a 2936 1.1 jruoho region field. A buffer object is also allowed as the source operand. BZ 480 2937 1.1 jruoho 2938 1.1 jruoho Fixed a problem where the Load ASL operator allowed the source operand to be 2939 1.1 jruoho an operation region of any type. It is now restricted to regions of type 2940 1.1 jruoho SystemMemory, as per the ACPI specification. BZ 481 2941 1.1 jruoho 2942 1.1 jruoho Additional cleanup and optimizations for the new Table Manager code. 2943 1.1 jruoho 2944 1.1 jruoho AcpiEnable will now fail if all of the required ACPI tables are not loaded 2945 1.1 jruoho (FADT, FACS, DSDT). BZ 477 2946 1.1 jruoho 2947 1.1 jruoho Added #pragma pack(8/4) to acobject.h to ensure that the structures in this 2948 1.1 jruoho header are always compiled as aligned. The ACPI_OPERAND_OBJECT has been 2949 1.1 jruoho manually optimized to be aligned and will not work if it is byte-packed. 2950 1.1 jruoho 2951 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 2952 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2953 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 2954 1.1 jruoho a much larger code and data size. 2955 1.1 jruoho 2956 1.1 jruoho Previous Release: 2957 1.1 jruoho Non-Debug Version: 78.1K Code, 17.1K Data, 95.2K Total 2958 1.1 jruoho Debug Version: 155.4K Code, 63.1K Data, 218.5K Total 2959 1.1 jruoho Current Release: 2960 1.1 jruoho Non-Debug Version: 77.9K Code, 17.0K Data, 94.9K Total 2961 1.1 jruoho Debug Version: 155.2K Code, 63.1K Data, 218.3K Total 2962 1.1 jruoho 2963 1.1 jruoho 2964 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 2965 1.1 jruoho 2966 1.1 jruoho Fixed a problem where the presence of the _OSI predefined control method 2967 1.1 jruoho within complex expressions could cause an internal compiler error. 2968 1.1 jruoho 2969 1.1 jruoho AcpiExec: Implemented full region support for multiple address spaces. 2970 1.1 jruoho SpaceId is now part of the REGION object. BZ 429 2971 1.1 jruoho 2972 1.1 jruoho ---------------------------------------- 2973 1.1 jruoho 11 October 2006. Summary of changes for version 20061011: 2974 1.1 jruoho 2975 1.1 jruoho 1) ACPI CA Core Subsystem: 2976 1.1 jruoho 2977 1.1 jruoho Completed an AML interpreter performance enhancement for control method 2978 1.1 jruoho execution. Previously a 2-pass parse/execution, control methods are now 2979 1.1 jruoho completely parsed and executed in a single pass. This improves overall 2980 1.1 jruoho interpreter performance by ~25%, reduces code size, and reduces CPU stack 2981 1.1 jruoho use. (Valery Podrezov + interpreter changes in version 20051202 that 2982 1.1 jruoho eliminated namespace loading during the pass one parse.) 2983 1.1 jruoho 2984 1.1 jruoho Implemented _CID support for PCI Root Bridge detection. If the _HID does not 2985 1.1 jruoho match the predefined PCI Root Bridge IDs, the _CID list (if present) is now 2986 1.1 jruoho obtained and also checked for an ID match. 2987 1.1 jruoho 2988 1.1 jruoho Implemented additional support for the PCI _ADR execution: upsearch until a 2989 1.1 jruoho device scope is found before executing _ADR. This allows PCI_Config 2990 1.1 jruoho operation regions to be declared locally within control methods underneath 2991 1.1 jruoho PCI device objects. 2992 1.1 jruoho 2993 1.1 jruoho Fixed a problem with a possible race condition between threads executing 2994 1.1 jruoho AcpiWalkNamespace and the AML interpreter. This condition was removed by 2995 1.1 jruoho modifying AcpiWalkNamespace to (by default) ignore all temporary namespace 2996 1.1 jruoho entries created during any concurrent control method execution. An 2997 1.1 jruoho additional namespace race condition is known to exist between 2998 1.1 jruoho AcpiWalkNamespace and the Load/Unload ASL operators and is still under 2999 1.1 jruoho investigation. 3000 1.1 jruoho 3001 1.1 jruoho Restructured the AML ParseLoop function, breaking it into several 3002 1.1 jruoho subfunctions in order to reduce CPU stack use and improve maintainability. 3003 1.1 jruoho (Mikhail Kouzmich) 3004 1.1 jruoho 3005 1.1 jruoho AcpiGetHandle: Fix for parameter validation to detect invalid combinations 3006 1.1 jruoho of prefix handle and pathname. BZ 478 3007 1.1 jruoho 3008 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3009 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3010 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3011 1.1 jruoho a much larger code and data size. 3012 1.1 jruoho 3013 1.1 jruoho Previous Release: 3014 1.1 jruoho Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total 3015 1.1 jruoho Debug Version: 154.6K Code, 63.0K Data, 217.6K Total 3016 1.1 jruoho Current Release: 3017 1.1 jruoho Non-Debug Version: 78.1K Code, 17.1K Data, 95.2K Total 3018 1.1 jruoho Debug Version: 155.4K Code, 63.1K Data, 218.5K Total 3019 1.1 jruoho 3020 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3021 1.1 jruoho 3022 1.1 jruoho Ported the -g option (get local ACPI tables) to the new ACPICA Table Manager 3023 1.1 jruoho to restore original behavior. 3024 1.1 jruoho 3025 1.1 jruoho ---------------------------------------- 3026 1.1 jruoho 27 September 2006. Summary of changes for version 20060927: 3027 1.1 jruoho 3028 1.1 jruoho 1) ACPI CA Core Subsystem: 3029 1.1 jruoho 3030 1.1 jruoho Removed the "Flags" parameter from AcpiGetRegister and AcpiSetRegister. 3031 1.1 jruoho These functions now use a spinlock for mutual exclusion and the interrupt 3032 1.1 jruoho level indication flag is not needed. 3033 1.1 jruoho 3034 1.1 jruoho Fixed a problem with the Global Lock where the lock could appear to be 3035 1.1 jruoho obtained before it is actually obtained. The global lock semaphore was 3036 1.1 jruoho inadvertently created with one unit instead of zero units. (BZ 464) Fiodor 3037 1.1 jruoho Suietov. 3038 1.1 jruoho 3039 1.1 jruoho Fixed a possible memory leak and fault in AcpiExResolveObjectToValue during 3040 1.1 jruoho a read from a buffer or region field. (BZ 458) Fiodor Suietov. 3041 1.1 jruoho 3042 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3043 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3044 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3045 1.1 jruoho a much larger code and data size. 3046 1.1 jruoho 3047 1.1 jruoho Previous Release: 3048 1.1 jruoho Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total 3049 1.1 jruoho Debug Version: 154.7K Code, 63.0K Data, 217.7K Total 3050 1.1 jruoho Current Release: 3051 1.1 jruoho Non-Debug Version: 77.9K Code, 17.1K Data, 95.0K Total 3052 1.1 jruoho Debug Version: 154.6K Code, 63.0K Data, 217.6K Total 3053 1.1 jruoho 3054 1.1 jruoho 3055 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3056 1.1 jruoho 3057 1.1 jruoho Fixed a compilation problem with the pre-defined Resource Descriptor field 3058 1.1 jruoho names where an "object does not exist" error could be incorrectly generated 3059 1.1 jruoho if the parent ResourceTemplate pathname places the template within a 3060 1.1 jruoho different namespace scope than the current scope. (BZ 7212) 3061 1.1 jruoho 3062 1.1 jruoho Fixed a problem where the compiler could hang after syntax errors detected 3063 1.1 jruoho in an ElseIf construct. (BZ 453) 3064 1.1 jruoho 3065 1.1 jruoho Fixed a problem with the AmlFilename parameter to the DefinitionBlock() 3066 1.1 jruoho operator. An incorrect output filename was produced when this parameter was 3067 1.1 jruoho a null string (""). Now, the original input filename is used as the AML 3068 1.1 jruoho output filename, with an ".aml" extension. 3069 1.1 jruoho 3070 1.1 jruoho Implemented a generic batch command mode for the AcpiExec utility (execute 3071 1.1 jruoho any AML debugger command) (Valery Podrezov). 3072 1.1 jruoho 3073 1.1 jruoho ---------------------------------------- 3074 1.1 jruoho 12 September 2006. Summary of changes for version 20060912: 3075 1.1 jruoho 3076 1.1 jruoho 1) ACPI CA Core Subsystem: 3077 1.1 jruoho 3078 1.1 jruoho Enhanced the implementation of the "serialized mode" of the interpreter 3079 1.1 jruoho (enabled via the AcpiGbl_AllMethodsSerialized flag.) When this mode is 3080 1.1 jruoho specified, instead of creating a serialization semaphore per control method, 3081 1.1 jruoho the interpreter lock is simply no longer released before a blocking 3082 1.1 jruoho operation during control method execution. This effectively makes the AML 3083 1.1 jruoho Interpreter single-threaded. The overhead of a semaphore per-method is 3084 1.1 jruoho eliminated. 3085 1.1 jruoho 3086 1.1 jruoho Fixed a regression where an error was no longer emitted if a control method 3087 1.1 jruoho attempts to create 2 objects of the same name. This once again returns 3088 1.1 jruoho AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism that 3089 1.1 jruoho will dynamically serialize the control method to possible prevent future 3090 1.1 jruoho errors. (BZ 440) 3091 1.1 jruoho 3092 1.1 jruoho Integrated a fix for a problem with PCI Express HID detection in the PCI 3093 1.1 jruoho Config Space setup procedure. (BZ 7145) 3094 1.1 jruoho 3095 1.1 jruoho Moved all FADT-related functions to a new file, tbfadt.c. Eliminated the 3096 1.1 jruoho AcpiHwInitialize function - the FADT registers are now validated when the 3097 1.1 jruoho table is loaded. 3098 1.1 jruoho 3099 1.1 jruoho Added two new warnings during FADT verification - 1) if the FADT is larger 3100 1.1 jruoho than the largest known FADT version, and 2) if there is a mismatch between a 3101 1.1 jruoho 32-bit block address and the 64-bit X counterpart (when both are non-zero.) 3102 1.1 jruoho 3103 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3104 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

This could cause a problem if the Switch() operator is 3121 1.1 jruoho within a while loop, causing an error on the second iteration. (BZ 460) 3122 1.1 jruoho 3123 1.1 jruoho Disassembler - fix for error emitted for unknown type for target of scope 3124 1.1 jruoho operator. Now, ignore it and continue. 3125 1.1 jruoho 3126 1.1 jruoho Disassembly of an FADT now verifies the input FADT and reports any errors 3127 1.1 jruoho found. Fix for proper disassembly of full-sized (ACPI 2.0) FADTs. 3128 1.1 jruoho 3129 1.1 jruoho Disassembly of raw data buffers with byte initialization data now prefixes 3130 1.1 jruoho each output line with the current buffer offset. 3131 1.1 jruoho 3132 1.1 jruoho Disassembly of ASF! table now includes all variable-length data fields at 3133 1.1 jruoho the end of some of the subtables. 3134 1.1 jruoho 3135 1.1 jruoho The disassembler now emits a comment if a buffer appears to be a 3136 1.1 jruoho ResourceTemplate, but cannot be disassembled as such because the EndTag does 3137 1.1 jruoho not appear at the very end of the buffer. 3138 1.1 jruoho 3139 1.1 jruoho AcpiExec - Added the "-t" command line option to enable the serialized mode 3140 1.1 jruoho of the AML interpreter. 3141 1.1 jruoho 3142 1.1 jruoho ---------------------------------------- 3143 1.1 jruoho 31 August 2006.

The 3167 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3168 1.1 jruoho a much larger code and data size. 3169 1.1 jruoho 3170 1.1 jruoho Previous Release: 3171 1.1 jruoho Non-Debug Version: 77.8K Code, 16.5K Data, 94.3K Total 3172 1.1 jruoho Debug Version: 154.6K Code, 62.3K Data, 216.9K Total 3173 1.1 jruoho Current Release: 3174 1.1 jruoho Non-Debug Version: 77.9K Code, 16.7K Data, 94.6K Total 3175 1.1 jruoho Debug Version: 154.9K Code, 62.6K Data, 217.5K Total 3176 1.1 jruoho 3177 1.1 jruoho 3178 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3179 1.1 jruoho 3180 1.1 jruoho Disassembler support for the DMAR ACPI table. 3181 1.1 jruoho 3182 1.1 jruoho ---------------------------------------- 3183 1.1 jruoho 23 August 2006. Summary of changes for version 20060823: 3184 1.1 jruoho 3185 1.1 jruoho 1) ACPI CA Core Subsystem: 3186 1.1 jruoho 3187 1.1 jruoho The Table Manager component has been completely redesigned and 3188 1.1 jruoho reimplemented. The new design is much simpler, and reduces the overall code 3189 1.1 jruoho and data size of the kernel-resident ACPICA by approximately 5%. Also, it is 3190 1.1 jruoho now possible to obtain the ACPI tables very early during kernel 3191 1.1 jruoho initialization, even before dynamic memory management is initialized. 3192 1.1 jruoho (Alexey Starikovskiy, Fiodor Suietov, Bob Moore) 3193 1.1 jruoho 3194 1.1 jruoho Obsolete ACPICA interfaces: 3195 1.1 jruoho 3196 1.1 jruoho - AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel init 3197 1.1 jruoho time). 3198 1.1 jruoho - AcpiLoadTable: Not needed. 3199 1.1 jruoho - AcpiUnloadTable: Not needed. 3200 1.1 jruoho 3201 1.1 jruoho New ACPICA interfaces: 3202 1.1 jruoho 3203 1.1 jruoho - AcpiInitializeTables: Must be called before the table manager can be used. 3204 1.1 jruoho - AcpiReallocateRootTable: Used to transfer the root table to dynamically 3205 1.1 jruoho allocated memory after it becomes available. 3206 1.1 jruoho - AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI tables 3207 1.1 jruoho in the RSDT/XSDT. 3208 1.1 jruoho 3209 1.1 jruoho Other ACPICA changes: 3210 1.1 jruoho 3211 1.1 jruoho - AcpiGetTableHeader returns the actual mapped table header, not a copy. Use 3212 1.1 jruoho AcpiOsUnmapMemory to free this mapping. 3213 1.1 jruoho - AcpiGetTable returns the actual mapped table. The mapping is managed 3214 1.1 jruoho internally and must not be deleted by the caller. Use of this interface 3215 1.1 jruoho causes no additional dynamic memory allocation. 3216 1.1 jruoho - AcpiFindRootPointer: Support for physical addressing has been eliminated, 3217 1.1 jruoho it appeared to be unused. 3218 1.1 jruoho - The interface to AcpiOsMapMemory has changed to be consistent with the 3219 1.1 jruoho other allocation interfaces. 3220 1.1 jruoho - The interface to AcpiOsGetRootPointer has changed to eliminate unnecessary 3221 1.1 jruoho parameters. 3222 1.1 jruoho - ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 64- 3223 1.1 jruoho bit platforms. Was previously 64 bits on all platforms. 3224 1.1 jruoho - The interface to the ACPI Global Lock acquire/release macros have changed 3225 1.1 jruoho slightly since ACPICA no longer keeps a local copy of the FACS with a 3226 1.1 jruoho constructed pointer to the actual global lock. 3227 1.1 jruoho 3228 1.1 jruoho Porting to the new table manager: 3229 1.1 jruoho 3230 1.1 jruoho - AcpiInitializeTables: Must be called once, and can be called anytime 3231 1.1 jruoho during the OS initialization process. It allows the host to specify an area 3232 1.1 jruoho of memory to be used to store the internal version of the RSDT/XSDT (root 3233 1.1 jruoho table). This allows the host to access ACPI tables before memory management 3234 1.1 jruoho is initialized and running. 3235 1.1 jruoho - AcpiReallocateRootTable: Can be called after memory management is running 3236 1.1 jruoho to copy the root table to a dynamically allocated array, freeing up the 3237 1.1 jruoho scratch memory specified in the call to AcpiInitializeTables. 3238 1.1 jruoho - AcpiSubsystemInitialize: This existing interface is independent of the 3239 1.1 jruoho Table Manager, and does not have to be called before the Table Manager can 3240 1.1 jruoho be used, it only must be called before the rest of ACPICA can be used. 3241 1.1 jruoho - ACPI Tables: Some changes have been made to the names and structure of the 3242 1.1 jruoho actbl.h and actbl1.h header files and may require changes to existing code. 3243 1.1 jruoho For example, bitfields have been completely removed because of their lack of 3244 1.1 jruoho portability across C compilers. 3245 1.1 jruoho - Update interfaces to the Global Lock acquire/release macros if local 3246 1.1 jruoho versions are used. (see acwin.h) 3247 1.1 jruoho 3248 1.1 jruoho Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c 3249 1.1 jruoho 3250 1.1 jruoho New files: tbfind.c 3251 1.1 jruoho 3252 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3253 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3254 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3255 1.1 jruoho a much larger code and data size. 3256 1.1 jruoho 3257 1.1 jruoho Previous Release: 3258 1.1 jruoho Non-Debug Version: 80.7K Code, 17.9K Data, 98.6K Total 3259 1.1 jruoho Debug Version: 161.0K Code, 65.1K Data, 226.1K Total 3260 1.1 jruoho Current Release: 3261 1.1 jruoho Non-Debug Version: 77.8K Code, 16.5K Data, 94.3K Total 3262 1.1 jruoho Debug Version: 154.6K Code, 62.3K Data, 216.9K Total 3263 1.1 jruoho 3264 1.1 jruoho 3265 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3266 1.1 jruoho 3267 1.1 jruoho No changes for this release. 3268 1.1 jruoho 3269 1.1 jruoho ---------------------------------------- 3270 1.1 jruoho 21 July 2006. Summary of changes for version 20060721: 3271 1.1 jruoho 3272 1.1 jruoho 1) ACPI CA Core Subsystem: 3273 1.1 jruoho 3274 1.1 jruoho The full source code for the ASL test suite used to validate the iASL 3275 1.1 jruoho compiler and the ACPICA core subsystem is being released with the ACPICA 3276 1.1 jruoho source for the first time. The source is contained in a separate package and 3277 1.1 jruoho consists of over 1100 files that exercise all ASL/AML operators. The package 3278 1.1 jruoho should appear on the Intel/ACPI web site shortly. (Valery Podrezov, Fiodor 3279 1.1 jruoho Suietov) 3280 1.1 jruoho 3281 1.1 jruoho Completed a new design and implementation for support of the ACPI Global 3282 1.1 jruoho Lock. On the OS side, the global lock is now treated as a standard AML 3283 1.1 jruoho mutex. Previously, multiple OS threads could "acquire" the global lock 3284 1.1 jruoho simultaneously. However, this could cause the BIOS to be starved out of the 3285 1.1 jruoho lock - especially in cases such as the Embedded Controller driver where 3286 1.1 jruoho there is a tight coupling between the OS and the BIOS. 3287 1.1 jruoho 3288 1.1 jruoho Implemented an optimization for the ACPI Global Lock interrupt mechanism. 3289 1.1 jruoho The Global Lock interrupt handler no longer queues the execution of a 3290 1.1 jruoho separate thread to signal the global lock semaphore. Instead, the semaphore 3291 1.1 jruoho is signaled directly from the interrupt handler. 3292 1.1 jruoho 3293 1.1 jruoho Implemented support within the AML interpreter for package objects that 3294 1.1 jruoho contain a larger AML length (package list length) than the package element 3295 1.1 jruoho count. In this case, the length of the package is truncated to match the 3296 1.1 jruoho package element count. Some BIOS code apparently modifies the package length 3297 1.1 jruoho on the fly, and this change supports this behavior. Provides compatibility 3298 1.1 jruoho with the MS AML interpreter. (With assistance from Fiodor Suietov) 3299 1.1 jruoho 3300 1.1 jruoho Implemented a temporary fix for the BankValue parameter of a Bank Field to 3301 1.1 jruoho support all constant values, now including the Zero and One opcodes. 3302 1.1 jruoho Evaluation of this parameter must eventually be converted to a full TermArg 3303 1.1 jruoho evaluation. A not-implemented error is now returned (temporarily) for non- 3304 1.1 jruoho constant values for this parameter. 3305 1.1 jruoho 3306 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 3307 1.1 jruoho - Fix for premature object deletion after CopyObject on Operation Region (BZ 3308 1.1 jruoho 350) 3309 1.1 jruoho 3310 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3311 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3312 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3313 1.1 jruoho a much larger code and data size. 3314 1.1 jruoho 3315 1.1 jruoho Previous Release: 3316 1.1 jruoho Non-Debug Version: 80.7K Code, 18.0K Data, 98.7K Total 3317 1.1 jruoho Debug Version: 160.9K Code, 65.1K Data, 226.0K Total 3318 1.1 jruoho Current Release: 3319 1.1 jruoho Non-Debug Version: 80.7K Code, 17.9K Data, 98.6K Total 3320 1.1 jruoho Debug Version: 161.0K Code, 65.1K Data, 226.1K Total 3321 1.1 jruoho 3322 1.1 jruoho 3323 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3324 1.1 jruoho 3325 1.1 jruoho No changes for this release. 3326 1.1 jruoho 3327 1.1 jruoho ---------------------------------------- 3328 1.1 jruoho 07 July 2006. Summary of changes for version 20060707: 3329 1.1 jruoho 3330 1.1 jruoho 1) ACPI CA Core Subsystem: 3331 1.1 jruoho 3332 1.1 jruoho Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to support C compilers 3333 1.1 jruoho that do not allow the initialization of address pointers within packed 3334 1.1 jruoho structures - even though the hardware itself may support misaligned 3335 1.1 jruoho transfers. Some of the debug data structures are packed by default to 3336 1.1 jruoho minimize size. 3337 1.1 jruoho 3338 1.1 jruoho Added an error message for the case where AcpiOsGetThreadId() returns zero. 3339 1.1 jruoho A non-zero value is required by the core ACPICA code to ensure the proper 3340 1.1 jruoho operation of AML mutexes and recursive control methods. 3341 1.1 jruoho 3342 1.1 jruoho The DSDT is now the only ACPI table that determines whether the AML 3343 1.1 jruoho interpreter is in 32-bit or 64-bit mode. Not really a functional change, but 3344 1.1 jruoho the hooks for per-table 32/64 switching have been removed from the code. A 3345 1.1 jruoho clarification to the ACPI specification is forthcoming in ACPI 3.0B. 3346 1.1 jruoho 3347 1.1 jruoho Fixed a possible leak of an OwnerID in the error path of 3348 1.1 jruoho AcpiTbInitTableDescriptor (tbinstal.c), and migrated all table OwnerID 3349 1.1 jruoho deletion to a single place in AcpiTbUninstallTable to correct possible leaks 3350 1.1 jruoho when using the AcpiTbDeleteTablesByType interface (with assistance from 3351 1.1 jruoho Lance Ortiz.) 3352 1.1 jruoho 3353 1.1 jruoho Fixed a problem with Serialized control methods where the semaphore 3354 1.1 jruoho associated with the method could be over-signaled after multiple method 3355 1.1 jruoho invocations. 3356 1.1 jruoho 3357 1.1 jruoho Fixed two issues with the locking of the internal namespace data structure. 3358 1.1 jruoho Both the Unload() operator and AcpiUnloadTable interface now lock the 3359 1.1 jruoho namespace during the namespace deletion associated with the table unload 3360 1.1 jruoho (with assistance from Linn Crosetto.) 3361 1.1 jruoho 3362 1.1 jruoho Fixed problem reports (Valery Podrezov) integrated: 3363 1.1 jruoho - Eliminate unnecessary memory allocation for CreateXxxxField (BZ 5426) 3364 1.1 jruoho 3365 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 3366 1.1 jruoho - Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369) 3367 1.1 jruoho - On Address Space handler deletion, needless deactivation call (BZ 374) 3368 1.1 jruoho - AcpiRemoveAddressSpaceHandler: validate Device handle parameter (BZ 375) 3369 1.1 jruoho - Possible memory leak, Notify sub-objects of Processor, Power, ThermalZone 3370 1.1 jruoho (BZ 376) 3371 1.1 jruoho - AcpiRemoveAddressSpaceHandler: validate Handler parameter (BZ 378) 3372 1.1 jruoho - Minimum Length of RSDT should be validated (BZ 379) 3373 1.1 jruoho - AcpiRemoveNotifyHandler: return AE_NOT_EXIST if Processor Obj has no 3374 1.1 jruoho Handler (BZ (380) 3375 1.1 jruoho - AcpiUnloadTable: return AE_NOT_EXIST if no table of specified type loaded 3376 1.1 jruoho (BZ 381) 3377 1.1 jruoho 3378 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3379 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3380 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3381 1.1 jruoho a much larger code and data size. 3382 1.1 jruoho 3383 1.1 jruoho Previous Release: 3384 1.1 jruoho Non-Debug Version: 80.5K Code, 17.8K Data, 98.3K Total 3385 1.1 jruoho Debug Version: 160.8K Code, 64.8K Data, 225.6K Total 3386 1.1 jruoho Current Release: 3387 1.1 jruoho Non-Debug Version: 80.7K Code, 17.9K Data, 98.6K Total 3388 1.1 jruoho Debug Version: 161.0K Code, 65.1K Data, 226.1K Total 3389 1.1 jruoho 3390 1.1 jruoho 3391 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3392 1.1 jruoho 3393 1.1 jruoho Fixed problem reports: 3394 1.1 jruoho Compiler segfault when ASL contains a long (>1024) String declaration (BZ 3395 1.1 jruoho 436) 3396 1.1 jruoho 3397 1.1 jruoho ---------------------------------------- 3398 1.1 jruoho 23 June 2006. Summary of changes for version 20060623: 3399 1.1 jruoho 3400 1.1 jruoho 1) ACPI CA Core Subsystem: 3401 1.1 jruoho 3402 1.1 jruoho Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This 3403 1.1 jruoho allows the type to be customized to the host OS for improved efficiency 3404 1.1 jruoho (since a spinlock is usually a very small object.) 3405 1.1 jruoho 3406 1.1 jruoho Implemented support for "ignored" bits in the ACPI registers. According to 3407 1.1 jruoho the ACPI specification, these bits should be preserved when writing the 3408 1.1 jruoho registers via a read/modify/write cycle. There are 3 bits preserved in this 3409 1.1 jruoho manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. 3410 1.1 jruoho 3411 1.1 jruoho Implemented the initial deployment of new OSL mutex interfaces. Since some 3412 1.1 jruoho host operating systems have separate mutex and semaphore objects, this 3413 1.1 jruoho feature was requested. The base code now uses mutexes (and the new mutex 3414 1.1 jruoho interfaces) wherever a binary semaphore was used previously. However, for 3415 1.1 jruoho the current release, the mutex interfaces are defined as macros to map them 3416 1.1 jruoho to the existing semaphore interfaces. Therefore, no OSL changes are required 3417 1.1 jruoho at this time. (See acpiosxf.h) 3418 1.1 jruoho 3419 1.1 jruoho Fixed several problems with the support for the control method SyncLevel 3420 1.1 jruoho parameter. The SyncLevel now works according to the ACPI specification and 3421 1.1 jruoho in concert with the Mutex SyncLevel parameter, since the current SyncLevel 3422 1.1 jruoho is a property of the executing thread. Mutual exclusion for control methods 3423 1.1 jruoho is now implemented with a mutex instead of a semaphore. 3424 1.1 jruoho 3425 1.1 jruoho Fixed three instances of the use of the C shift operator in the bitfield 3426 1.1 jruoho support code (exfldio.c) to avoid the use of a shift value larger than the 3427 1.1 jruoho target data width. The behavior of C compilers is undefined in this case and 3428 1.1 jruoho can cause unpredictable results, and therefore the case must be detected and 3429 1.1 jruoho avoided. (Fiodor Suietov) 3430 1.1 jruoho 3431 1.1 jruoho Added an info message whenever an SSDT or OEM table is loaded dynamically 3432 1.1 jruoho via the Load() or LoadTable() ASL operators. This should improve debugging 3433 1.1 jruoho capability since it will show exactly what tables have been loaded (beyond 3434 1.1 jruoho the tables present in the RSDT/XSDT.) 3435 1.1 jruoho 3436 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3437 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3438 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3439 1.1 jruoho a much larger code and data size. 3440 1.1 jruoho 3441 1.1 jruoho Previous Release: 3442 1.1 jruoho Non-Debug Version: 80.0K Code, 17.6K Data, 97.6K Total 3443 1.1 jruoho Debug Version: 160.2K Code, 64.7K Data, 224.9K Total 3444 1.1 jruoho Current Release: 3445 1.1 jruoho Non-Debug Version: 80.5K Code, 17.8K Data, 98.3K Total 3446 1.1 jruoho Debug Version: 160.8K Code, 64.8K Data, 225.6K Total 3447 1.1 jruoho 3448 1.1 jruoho 3449 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3450 1.1 jruoho 3451 1.1 jruoho No changes for this release. 3452 1.1 jruoho 3453 1.1 jruoho ---------------------------------------- 3454 1.1 jruoho 08 June 2006. Summary of changes for version 20060608: 3455 1.1 jruoho 3456 1.1 jruoho 1) ACPI CA Core Subsystem: 3457 1.1 jruoho 3458 1.1 jruoho Converted the locking mutex used for the ACPI hardware to a spinlock. This 3459 1.1 jruoho change should eliminate all problems caused by attempting to acquire a 3460 1.1 jruoho semaphore at interrupt level, and it means that all ACPICA external 3461 1.1 jruoho interfaces that directly access the ACPI hardware can be safely called from 3462 1.1 jruoho interrupt level. OSL code that implements the semaphore interfaces should be 3463 1.1 jruoho able to eliminate any workarounds for being called at interrupt level. 3464 1.1 jruoho 3465 1.1 jruoho Fixed a regression introduced in 20060526 where the ACPI device 3466 1.1 jruoho initialization could be prematurely aborted with an AE_NOT_FOUND if a device 3467 1.1 jruoho did not have an optional _INI method. 3468 1.1 jruoho 3469 1.1 jruoho Fixed an IndexField issue where a write to the Data Register should be 3470 1.1 jruoho limited in size to the AccessSize (width) of the IndexField itself. (BZ 433, 3471 1.1 jruoho Fiodor Suietov) 3472 1.1 jruoho 3473 1.1 jruoho Fixed problem reports (Valery Podrezov) integrated: 3474 1.1 jruoho - Allow store of ThermalZone objects to Debug object (BZ 5369/5370) 3475 1.1 jruoho 3476 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 3477 1.1 jruoho - AcpiGetTableHeader doesn't handle multiple instances correctly (BZ 364) 3478 1.1 jruoho 3479 1.1 jruoho Removed four global mutexes that were obsolete and were no longer being 3480 1.1 jruoho used. 3481 1.1 jruoho 3482 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3483 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3484 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3485 1.1 jruoho a much larger code and data size. 3486 1.1 jruoho 3487 1.1 jruoho Previous Release: 3488 1.1 jruoho Non-Debug Version: 80.0K Code, 17.7K Data, 97.7K Total 3489 1.1 jruoho Debug Version: 160.3K Code, 64.9K Data, 225.2K Total 3490 1.1 jruoho Current Release: 3491 1.1 jruoho Non-Debug Version: 80.0K Code, 17.6K Data, 97.6K Total 3492 1.1 jruoho Debug Version: 160.2K Code, 64.7K Data, 224.9K Total 3493 1.1 jruoho 3494 1.1 jruoho 3495 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3496 1.1 jruoho 3497 1.1 jruoho Fixed a fault when using -g option (get tables from registry) on Windows 3498 1.1 jruoho machines. 3499 1.1 jruoho 3500 1.1 jruoho Fixed problem reports integrated: 3501 1.1 jruoho - Generate error if CreateField NumBits parameter is zero. (BZ 405) 3502 1.1 jruoho - Fault if Offset/Length in Field unit is very large (BZ 432, Fiodor 3503 1.1 jruoho Suietov) 3504 1.1 jruoho - Global table revision override (-r) is ignored (BZ 413) 3505 1.1 jruoho 3506 1.1 jruoho ---------------------------------------- 3507 1.1 jruoho 26 May 2006. Summary of changes for version 20060526: 3508 1.1 jruoho 3509 1.1 jruoho 1) ACPI CA Core Subsystem: 3510 1.1 jruoho 3511 1.1 jruoho Restructured, flattened, and simplified the internal interfaces for 3512 1.1 jruoho namespace object evaluation - resulting in smaller code, less CPU stack use, 3513 1.1 jruoho and fewer interfaces. (With assistance from Mikhail Kouzmich) 3514 1.1 jruoho 3515 1.1 jruoho Fixed a problem with the CopyObject operator where the first parameter was 3516 1.1 jruoho not typed correctly for the parser, interpreter, compiler, and disassembler. 3517 1.1 jruoho Caused various errors and unexpected behavior. 3518 1.1 jruoho 3519 1.1 jruoho Fixed a problem where a ShiftLeft or ShiftRight of more than 64 bits 3520 1.1 jruoho produced incorrect results with some C compilers. Since the behavior of C 3521 1.1 jruoho compilers when the shift value is larger than the datatype width is 3522 1.1 jruoho apparently not well defined, the interpreter now detects this condition and 3523 1.1 jruoho simply returns zero as expected in all such cases. (BZ 395) 3524 1.1 jruoho 3525 1.1 jruoho Fixed problem reports (Valery Podrezov) integrated: 3526 1.1 jruoho - Update String-to-Integer conversion to match ACPI 3.0A spec (BZ 5329) 3527 1.1 jruoho - Allow interpreter to handle nested method declarations (BZ 5361) 3528 1.1 jruoho 3529 1.1 jruoho Fixed problem reports (Fiodor Suietov) integrated: 3530 1.1 jruoho - AcpiTerminate doesn't free debug memory allocation list objects (BZ 355) 3531 1.1 jruoho - After Core Subsystem shutdown, AcpiSubsystemStatus returns AE_OK (BZ 356) 3532 1.1 jruoho - AcpiOsUnmapMemory for RSDP can be invoked inconsistently (BZ 357) 3533 1.1 jruoho - Resource Manager should return AE_TYPE for non-device objects (BZ 358) 3534 1.1 jruoho - Incomplete cleanup branch in AcpiNsEvaluateRelative (BZ 359) 3535 1.1 jruoho - Use AcpiOsFree instead of ACPI_FREE in AcpiRsSetSrsMethodData (BZ 360) 3536 1.1 jruoho - Incomplete cleanup branch in AcpiPsParseAml (BZ 361) 3537 1.1 jruoho - Incomplete cleanup branch in AcpiDsDeleteWalkState (BZ 362) 3538 1.1 jruoho - AcpiGetTableHeader returns AE_NO_ACPI_TABLES until DSDT is loaded (BZ 365) 3539 1.1 jruoho - Status of the Global Initialization Handler call not used (BZ 366) 3540 1.1 jruoho - Incorrect object parameter to Global Initialization Handler (BZ 367) 3541 1.1 jruoho 3542 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3543 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3544 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3545 1.1 jruoho a much larger code and data size. 3546 1.1 jruoho 3547 1.1 jruoho Previous Release: 3548 1.1 jruoho Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total 3549 1.1 jruoho Debug Version: 160.5K Code, 65.1K Data, 225.6K Total 3550 1.1 jruoho Current Release: 3551 1.1 jruoho Non-Debug Version: 80.0K Code, 17.7K Data, 97.7K Total 3552 1.1 jruoho Debug Version: 160.3K Code, 64.9K Data, 225.2K Total 3553 1.1 jruoho 3554 1.1 jruoho 3555 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3556 1.1 jruoho 3557 1.1 jruoho Modified the parser to allow the names IO, DMA, and IRQ to be used as 3558 1.1 jruoho namespace identifiers with no collision with existing resource descriptor 3559 1.1 jruoho macro names. This provides compatibility with other ASL compilers and is 3560 1.1 jruoho most useful for disassembly/recompilation of existing tables without parse 3561 1.1 jruoho errors. (With assistance from Thomas Renninger) 3562 1.1 jruoho 3563 1.1 jruoho Disassembler: fixed an incorrect disassembly problem with the 3564 1.1 jruoho DataTableRegion and CopyObject operators. Fixed a possible fault during 3565 1.1 jruoho disassembly of some Alias operators. 3566 1.1 jruoho 3567 1.1 jruoho ---------------------------------------- 3568 1.1 jruoho 12 May 2006. Summary of changes for version 20060512: 3569 1.1 jruoho 3570 1.1 jruoho 1) ACPI CA Core Subsystem: 3571 1.1 jruoho 3572 1.1 jruoho Replaced the AcpiOsQueueForExecution interface with a new interface named 3573 1.1 jruoho AcpiOsExecute. The major difference is that the new interface does not have 3574 1.1 jruoho a Priority parameter, this appeared to be useless and has been replaced by a 3575 1.1 jruoho Type parameter. The Type tells the host what type of execution is being 3576 1.1 jruoho requested, such as global lock handler, notify handler, GPE handler, etc. 3577 1.1 jruoho This allows the host to queue and execute the request as appropriate for the 3578 1.1 jruoho request type, possibly using different work queues and different priorities 3579 1.1 jruoho for the various request types. This enables fixes for multithreading 3580 1.1 jruoho deadlock problems such as BZ #5534, and will require changes to all existing 3581 1.1 jruoho OS interface layers. (Alexey Starikovskiy and Bob Moore) 3582 1.1 jruoho 3583 1.1 jruoho Fixed a possible memory leak associated with the support for the so-called 3584 1.1 jruoho "implicit return" ACPI extension. Reported by FreeBSD, BZ #6514. (Fiodor 3585 1.1 jruoho Suietov) 3586 1.1 jruoho 3587 1.1 jruoho Fixed a problem with the Load() operator where a table load from an 3588 1.1 jruoho operation region could overwrite an internal table buffer by up to 7 bytes 3589 1.1 jruoho and cause alignment faults on IPF systems. (With assistance from Luming Yu) 3590 1.1 jruoho 3591 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3592 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3593 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3594 1.1 jruoho a much larger code and data size. 3595 1.1 jruoho 3596 1.1 jruoho Previous Release: 3597 1.1 jruoho Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total 3598 1.1 jruoho Debug Version: 160.1K Code, 65.2K Data, 225.3K Total 3599 1.1 jruoho Current Release: 3600 1.1 jruoho Non-Debug Version: 79.8K Code, 17.7K Data, 97.5K Total 3601 1.1 jruoho Debug Version: 160.5K Code, 65.1K Data, 225.6K Total 3602 1.1 jruoho 3603 1.1 jruoho 3604 1.1 jruoho 3605 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3606 1.1 jruoho 3607 1.1 jruoho Disassembler: Implemented support to cross reference the internal namespace 3608 1.1 jruoho and automatically generate ASL External() statements for symbols not defined 3609 1.1 jruoho within the current table being disassembled. This will simplify the 3610 1.1 jruoho disassembly and recompilation of interdependent tables such as SSDTs since 3611 1.1 jruoho these statements will no longer have to be added manually. 3612 1.1 jruoho 3613 1.1 jruoho Disassembler: Implemented experimental support to automatically detect 3614 1.1 jruoho invocations of external control methods and generate appropriate External() 3615 1.1 jruoho statements. This is problematic because the AML cannot be correctly parsed 3616 1.1 jruoho until the number of arguments for each control method is known. Currently, 3617 1.1 jruoho standalone method invocations and invocations as the source operand of a 3618 1.1 jruoho Store() statement are supported. 3619 1.1 jruoho 3620 1.1 jruoho Disassembler: Implemented support for the ASL pseudo-operators LNotEqual, 3621 1.1 jruoho LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()), 3622 1.1 jruoho LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code 3623 1.1 jruoho more readable and likely closer to the original ASL source. 3624 1.1 jruoho 3625 1.1 jruoho ---------------------------------------- 3626 1.1 jruoho 21 April 2006. Summary of changes for version 20060421: 3627 1.1 jruoho 3628 1.1 jruoho 1) ACPI CA Core Subsystem: 3629 1.1 jruoho 3630 1.1 jruoho Removed a device initialization optimization introduced in 20051216 where 3631 1.1 jruoho the _STA method was not run unless an _INI was also present for the same 3632 1.1 jruoho device. This optimization could cause problems because it could allow _INI 3633 1.1 jruoho methods to be run within a not-present device subtree. (If a not-present 3634 1.1 jruoho device had no _INI, _STA would not be run, the not-present status would not 3635 1.1 jruoho be discovered, and the children of the device would be incorrectly 3636 1.1 jruoho traversed.) 3637 1.1 jruoho 3638 1.1 jruoho Implemented a new _STA optimization where namespace subtrees that do not 3639 1.1 jruoho contain _INI are identified and ignored during device initialization. 3640 1.1 jruoho Selectively running _STA can significantly improve boot time on large 3641 1.1 jruoho machines (with assistance from Len Brown.) 3642 1.1 jruoho 3643 1.1 jruoho Implemented support for the device initialization case where the returned 3644 1.1 jruoho _STA flags indicate a device not-present but functioning. In this case, _INI 3645 1.1 jruoho is not run, but the device children are examined for presence, as per the 3646 1.1 jruoho ACPI specification. 3647 1.1 jruoho 3648 1.1 jruoho Implemented an additional change to the IndexField support in order to 3649 1.1 jruoho conform to MS behavior. The value written to the Index Register is not 3650 1.1 jruoho simply a byte offset, it is a byte offset in units of the access width of 3651 1.1 jruoho the parent Index Field. (Fiodor Suietov) 3652 1.1 jruoho 3653 1.1 jruoho Defined and deployed a new OSL interface, AcpiOsValidateAddress. This 3654 1.1 jruoho interface is called during the creation of all AML operation regions, and 3655 1.1 jruoho allows the host OS to exert control over what addresses it will allow the 3656 1.1 jruoho AML code to access. Operation Regions whose addresses are disallowed will 3657 1.1 jruoho cause a runtime exception when they are actually accessed (will not affect 3658 1.1 jruoho or abort table loading.) See oswinxf or osunixxf for an example 3659 1.1 jruoho implementation. 3660 1.1 jruoho 3661 1.1 jruoho Defined and deployed a new OSL interface, AcpiOsValidateInterface. This 3662 1.1 jruoho interface allows the host OS to match the various "optional" 3663 1.1 jruoho interface/behavior strings for the _OSI predefined control method as 3664 1.1 jruoho appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf 3665 1.1 jruoho for an example implementation. 3666 1.1 jruoho 3667 1.1 jruoho Restructured and corrected various problems in the exception handling code 3668 1.1 jruoho paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod 3669 1.1 jruoho (with assistance from Takayoshi Kochi.) 3670 1.1 jruoho 3671 1.1 jruoho Modified the Linux source converter to ignore quoted string literals while 3672 1.1 jruoho converting identifiers from mixed to lower case. This will correct problems 3673 1.1 jruoho with the disassembler and other areas where such strings must not be 3674 1.1 jruoho modified. 3675 1.1 jruoho 3676 1.1 jruoho The ACPI_FUNCTION_* macros no longer require quotes around the function 3677 1.1 jruoho name. This allows the Linux source converter to convert the names, now that 3678 1.1 jruoho the converter ignores quoted strings. 3679 1.1 jruoho 3680 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3681 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3682 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3683 1.1 jruoho a much larger code and data size. 3684 1.1 jruoho 3685 1.1 jruoho Previous Release: 3686 1.1 jruoho 3687 1.1 jruoho Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 3688 1.1 jruoho Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 3689 1.1 jruoho Current Release: 3690 1.1 jruoho Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total 3691 1.1 jruoho Debug Version: 160.1K Code, 65.2K Data, 225.3K Total 3692 1.1 jruoho 3693 1.1 jruoho 3694 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3695 1.1 jruoho 3696 1.1 jruoho Implemented 3 new warnings for iASL, and implemented multiple warning levels 3697 1.1 jruoho (w2 flag). 3698 1.1 jruoho 3699 1.1 jruoho 1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is not 3700 1.1 jruoho WAIT_FOREVER (0xFFFF) and the code does not examine the return value to 3701 1.1 jruoho check for the possible timeout, a warning is issued. 3702 1.1 jruoho 3703 1.1 jruoho 2) Useless operators: If an ASL operator does not specify an optional target 3704 1.1 jruoho operand and it also does not use the function return value from the 3705 1.1 jruoho operator, a warning is issued since the operator effectively does nothing. 3706 1.1 jruoho 3707 1.1 jruoho 3) Unreferenced objects: If a namespace object is created, but never 3708 1.1 jruoho referenced, a warning is issued. This is a warning level 2 since there are 3709 1.1 jruoho cases where this is ok, such as when a secondary table is loaded that uses 3710 1.1 jruoho the unreferenced objects. Even so, care is taken to only flag objects that 3711 1.1 jruoho don't look like they will ever be used. For example, the reserved methods 3712 1.1 jruoho (starting with an underscore) are usually not referenced because it is 3713 1.1 jruoho expected that the OS will invoke them. 3714 1.1 jruoho 3715 1.1 jruoho ---------------------------------------- 3716 1.1 jruoho 31 March 2006. Summary of changes for version 20060331: 3717 1.1 jruoho 3718 1.1 jruoho 1) ACPI CA Core Subsystem: 3719 1.1 jruoho 3720 1.1 jruoho Implemented header file support for the following additional ACPI tables: 3721 1.1 jruoho ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, 3722 1.1 jruoho all current and known ACPI tables are now defined in the ACPICA headers and 3723 1.1 jruoho are available for use by device drivers and other software. 3724 1.1 jruoho 3725 1.1 jruoho Implemented support to allow tables that contain ACPI names with invalid 3726 1.1 jruoho characters to be loaded. Previously, this would cause the table load to 3727 1.1 jruoho fail, but since there are several known cases of such tables on existing 3728 1.1 jruoho machines, this change was made to enable ACPI support for them. Also, this 3729 1.1 jruoho matches the behavior of the Microsoft ACPI implementation. 3730 1.1 jruoho 3731 1.1 jruoho Fixed a couple regressions introduced during the memory optimization in the 3732 1.1 jruoho 20060317 release. The namespace node definition required additional 3733 1.1 jruoho reorganization and an internal datatype that had been changed to 8-bit was 3734 1.1 jruoho restored to 32-bit. (Valery Podrezov) 3735 1.1 jruoho 3736 1.1 jruoho Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState 3737 1.1 jruoho could be passed through to AcpiOsReleaseObject which is unexpected. Such 3738 1.1 jruoho null pointers are now trapped and ignored, matching the behavior of the 3739 1.1 jruoho previous implementation before the deployment of AcpiOsReleaseObject. 3740 1.1 jruoho (Valery Podrezov, Fiodor Suietov) 3741 1.1 jruoho 3742 1.1 jruoho Fixed a memory mapping leak during the deletion of a SystemMemory operation 3743 1.1 jruoho region where a cached memory mapping was not deleted. This became a 3744 1.1 jruoho noticeable problem for operation regions that are defined within frequently 3745 1.1 jruoho used control methods. (Dana Meyers) 3746 1.1 jruoho 3747 1.1 jruoho Reorganized the ACPI table header files into two main files: one for the 3748 1.1 jruoho ACPI tables consumed by the ACPICA core, and another for the miscellaneous 3749 1.1 jruoho ACPI tables that are consumed by the drivers and other software. The various 3750 1.1 jruoho FADT definitions were merged into one common section and three different 3751 1.1 jruoho tables (ACPI 1.0, 1.0+, and 2.0) 3752 1.1 jruoho 3753 1.1 jruoho Example Code and Data Size: These are the sizes for the OS-independent 3754 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3755 1.1 jruoho debug version of the code includes the debug output trace mechanism and has 3756 1.1 jruoho a much larger code and data size. 3757 1.1 jruoho 3758 1.1 jruoho Previous Release: 3759 1.1 jruoho Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 3760 1.1 jruoho Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 3761 1.1 jruoho Current Release: 3762 1.1 jruoho Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 3763 1.1 jruoho Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 3764 1.1 jruoho 3765 1.1 jruoho 3766 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3767 1.1 jruoho 3768 1.1 jruoho Disassembler: Implemented support to decode and format all non-AML ACPI 3769 1.1 jruoho tables (tables other than DSDTs and SSDTs.) This includes the new tables 3770 1.1 jruoho added to the ACPICA headers, therefore all current and known ACPI tables are 3771 1.1 jruoho supported. 3772 1.1 jruoho 3773 1.1 jruoho Disassembler: The change to allow ACPI names with invalid characters also 3774 1.1 jruoho enables the disassembly of such tables. Invalid characters within names are 3775 1.1 jruoho changed to '*' to make the name printable; the iASL compiler will still 3776 1.1 jruoho generate an error for such names, however, since this is an invalid ACPI 3777 1.1 jruoho character. 3778 1.1 jruoho 3779 1.1 jruoho Implemented an option for AcpiXtract (-a) to extract all tables found in the 3780 1.1 jruoho input file. The default invocation extracts only the DSDTs and SSDTs. 3781 1.1 jruoho 3782 1.1 jruoho Fixed a couple of gcc generation issues for iASL and AcpiExec and added a 3783 1.1 jruoho makefile for the AcpiXtract utility. 3784 1.1 jruoho 3785 1.1 jruoho ---------------------------------------- 3786 1.1 jruoho 17 March 2006. Summary of changes for version 20060317: 3787 1.1 jruoho 3788 1.1 jruoho 1) ACPI CA Core Subsystem: 3789 1.1 jruoho 3790 1.1 jruoho Implemented the use of a cache object for all internal namespace nodes. 3791 1.1 jruoho Since there are about 1000 static nodes in a typical system, this will 3792 1.1 jruoho decrease memory use for cache implementations that minimize per-allocation 3793 1.1 jruoho overhead (such as a slab allocator.) 3794 1.1 jruoho 3795 1.1 jruoho Removed the reference count mechanism for internal namespace nodes, since it 3796 1.1 jruoho was deemed unnecessary. This reduces the size of each namespace node by 3797 1.1 jruoho about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, 3798 1.1 jruoho and 32 bytes for the 64-bit case. 3799 1.1 jruoho 3800 1.1 jruoho Optimized several internal data structures to reduce object size on 64-bit 3801 1.1 jruoho platforms by packing data within the 64-bit alignment. This includes the 3802 1.1 jruoho frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static 3803 1.1 jruoho instances corresponding to the namespace objects. 3804 1.1 jruoho 3805 1.1 jruoho Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" 3806 1.1 jruoho and "Windows 2006". 3807 1.1 jruoho 3808 1.1 jruoho Split the allocation tracking mechanism out to a separate file, from 3809 1.1 jruoho utalloc.c to uttrack.c. This mechanism appears to be only useful for 3810 1.1 jruoho application-level code. Kernels may wish to not include uttrack.c in 3811 1.1 jruoho distributions. 3812 1.1 jruoho 3813 1.1 jruoho Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated 3814 1.1 jruoho code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING 3815 1.1 jruoho macros.) 3816 1.1 jruoho 3817 1.1 jruoho Code and Data Size: These are the sizes for the acpica.lib produced by the 3818 1.1 jruoho Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 3819 1.1 jruoho driver or OSPM code. The debug version of the code includes the debug output 3820 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 3821 1.1 jruoho values will vary depending on the efficiency of the compiler and the 3822 1.1 jruoho compiler options used during generation. 3823 1.1 jruoho 3824 1.1 jruoho Previous Release: 3825 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 3826 1.1 jruoho Debug Version: 161.6K Code, 65.7K Data, 227.3K Total 3827 1.1 jruoho Current Release: 3828 1.1 jruoho Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 3829 1.1 jruoho Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 3830 1.1 jruoho 3831 1.1 jruoho 3832 1.1 jruoho 2) iASL Compiler/Disassembler and Tools: 3833 1.1 jruoho 3834 1.1 jruoho Implemented an ANSI C version of the acpixtract utility. This version will 3835 1.1 jruoho automatically extract the DSDT and all SSDTs from the input acpidump text 3836 1.1 jruoho file and dump the binary output to separate files. It can also display a 3837 1.1 jruoho summary of the input file including the headers for each table found and 3838 1.1 jruoho will extract any single ACPI table, with any signature. (See 3839 1.1 jruoho source/tools/acpixtract) 3840 1.1 jruoho 3841 1.1 jruoho ---------------------------------------- 3842 1.1 jruoho 10 March 2006. Summary of changes for version 20060310: 3843 1.1 jruoho 3844 1.1 jruoho 1) ACPI CA Core Subsystem: 3845 1.1 jruoho 3846 1.1 jruoho Tagged all external interfaces to the subsystem with the new 3847 1.1 jruoho ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist 3848 1.1 jruoho kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL 3849 1.1 jruoho macro. The default definition is NULL. 3850 1.1 jruoho 3851 1.1 jruoho Added the ACPI_THREAD_ID type for the return value from AcpiOsGetThreadId. 3852 1.1 jruoho This allows the host to define this as necessary to simplify kernel 3853 1.1 jruoho integration. The default definition is ACPI_NATIVE_UINT. 3854 1.1 jruoho 3855 1.1 jruoho Fixed two interpreter problems related to error processing, the deletion of 3856 1.1 jruoho objects, and placing invalid pointers onto the internal operator result 3857 1.1 jruoho stack. BZ 6028, 6151 (Valery Podrezov) 3858 1.1 jruoho 3859 1.1 jruoho Increased the reference count threshold where a warning is emitted for large 3860 1.1 jruoho reference counts in order to eliminate unnecessary warnings on systems with 3861 1.1 jruoho large namespaces (especially 64-bit.) Increased the value from 0x400 to 3862 1.1 jruoho 0x800. 3863 1.1 jruoho 3864 1.1 jruoho Due to universal disagreement as to the meaning of the 'c' in the calloc() 3865 1.1 jruoho function, the ACPI_MEM_CALLOCATE macro has been renamed to 3866 1.1 jruoho ACPI_ALLOCATE_ZEROED so that the purpose of the interface is 'clear'. 3867 1.1 jruoho ACPI_MEM_ALLOCATE and ACPI_MEM_FREE are renamed to ACPI_ALLOCATE and 3868 1.1 jruoho ACPI_FREE. 3869 1.1 jruoho 3870 1.1 jruoho Code and Data Size: These are the sizes for the acpica.lib produced by the 3871 1.1 jruoho Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 3872 1.1 jruoho driver or OSPM code. The debug version of the code includes the debug output 3873 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 3874 1.1 jruoho values will vary depending on the efficiency of the compiler and the 3875 1.1 jruoho compiler options used during generation. 3876 1.1 jruoho 3877 1.1 jruoho Previous Release: 3878 1.1 jruoho Non-Debug Version: 81.0K Code, 17.8K Data, 98.8K Total 3879 1.1 jruoho Debug Version: 161.4K Code, 65.7K Data, 227.1K Total 3880 1.1 jruoho Current Release: 3881 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 3882 1.1 jruoho Debug Version: 161.6K Code, 65.7K Data, 227.3K Total 3883 1.1 jruoho 3884 1.1 jruoho 3885 1.1 jruoho 2) iASL Compiler/Disassembler: 3886 1.1 jruoho 3887 1.1 jruoho Disassembler: implemented support for symbolic resource descriptor 3888 1.1 jruoho references. If a CreateXxxxField operator references a fixed offset within a 3889 1.1 jruoho resource descriptor, a name is assigned to the descriptor and the offset is 3890 1.1 jruoho translated to the appropriate resource tag and pathname. The addition of 3891 1.1 jruoho this support brings the disassembled code very close to the original ASL 3892 1.1 jruoho source code and helps eliminate run-time errors when the disassembled code 3893 1.1 jruoho is modified (and recompiled) in such a way as to invalidate the original 3894 1.1 jruoho fixed offsets. 3895 1.1 jruoho 3896 1.1 jruoho Implemented support for a Descriptor Name as the last parameter to the ASL 3897 1.1 jruoho Register() macro. This parameter was inadvertently left out of the ACPI 3898 1.1 jruoho specification, and will be added for ACPI 3.0b. 3899 1.1 jruoho 3900 1.1 jruoho Fixed a problem where the use of the "_OSI" string (versus the full path 3901 1.1 jruoho "\_OSI") caused an internal compiler error. ("No back ptr to op") 3902 1.1 jruoho 3903 1.1 jruoho Fixed a problem with the error message that occurs when an invalid string is 3904 1.1 jruoho used for a _HID object (such as one with an embedded asterisk: "*PNP010A".) 3905 1.1 jruoho The correct message is now displayed. 3906 1.1 jruoho 3907 1.1 jruoho ---------------------------------------- 3908 1.1 jruoho 17 February 2006. Summary of changes for version 20060217: 3909 1.1 jruoho 3910 1.1 jruoho 1) ACPI CA Core Subsystem: 3911 1.1 jruoho 3912 1.1 jruoho Implemented a change to the IndexField support to match the behavior of the 3913 1.1 jruoho Microsoft AML interpreter. The value written to the Index register is now a 3914 1.1 jruoho byte offset, no longer an index based upon the width of the Data register. 3915 1.1 jruoho This should fix IndexField problems seen on some machines where the Data 3916 1.1 jruoho register is not exactly one byte wide. The ACPI specification will be 3917 1.1 jruoho clarified on this point. 3918 1.1 jruoho 3919 1.1 jruoho Fixed a problem where several resource descriptor types could overrun the 3920 1.1 jruoho internal descriptor buffer due to size miscalculation: VendorShort, 3921 1.1 jruoho VendorLong, and Interrupt. This was noticed on IA64 machines, but could 3922 1.1 jruoho affect all platforms. 3923 1.1 jruoho 3924 1.1 jruoho Fixed a problem where individual resource descriptors were misaligned within 3925 1.1 jruoho the internal buffer, causing alignment faults on IA64 platforms. 3926 1.1 jruoho 3927 1.1 jruoho Code and Data Size: These are the sizes for the acpica.lib produced by the 3928 1.1 jruoho Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 3929 1.1 jruoho driver or OSPM code. The debug version of the code includes the debug output 3930 1.1 jruoho trace mechanism and has a much larger code and data size. Note that these 3931 1.1 jruoho values will vary depending on the efficiency of the compiler and the 3932 1.1 jruoho compiler options used during generation. 3933 1.1 jruoho 3934 1.1 jruoho Previous Release: 3935 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 3936 1.1 jruoho Debug Version: 161.3K Code, 65.6K Data, 226.9K Total 3937 1.1 jruoho Current Release: 3938 1.1 jruoho Non-Debug Version: 81.0K Code, 17.8K Data, 98.8K Total 3939 1.1 jruoho Debug Version: 161.4K Code, 65.7K Data, 227.1K Total 3940 1.1 jruoho 3941 1.1 jruoho 3942 1.1 jruoho 2) iASL Compiler/Disassembler: 3943 1.1 jruoho 3944 1.1 jruoho Implemented support for new reserved names: _WDG and _WED are Microsoft 3945 1.1 jruoho extensions for Windows Instrumentation Management, _TDL is a new ACPI- 3946 1.1 jruoho defined method (Throttling Depth Limit.) 3947 1.1 jruoho 3948 1.1 jruoho Fixed a problem where a zero-length VendorShort or VendorLong resource 3949 1.1 jruoho descriptor was incorrectly emitted as a descriptor of length one. 3950 1.1 jruoho 3951 1.1 jruoho ---------------------------------------- 3952 1.1 jruoho 10 February 2006. Summary of changes for version 20060210: 3953 1.1 jruoho 3954 1.1 jruoho 1) ACPI CA Core Subsystem: 3955 1.1 jruoho 3956 1.1 jruoho Removed a couple of extraneous ACPI_ERROR messages that appeared during 3957 1.1 jruoho normal execution. These became apparent after the conversion from 3958 1.1 jruoho ACPI_DEBUG_PRINT. 3959 1.1 jruoho 3960 1.1 jruoho Fixed a problem where the CreateField operator could hang if the BitIndex or 3961 1.1 jruoho NumBits parameter referred to a named object. (Valery Podrezov, BZ 5359) 3962 1.1 jruoho 3963 1.1 jruoho Fixed a problem where a DeRefOf operation on a buffer object incorrectly 3964 1.1 jruoho failed with an exception. This also fixes a couple of related RefOf and 3965 1.1 jruoho DeRefOf issues. (Valery Podrezov, BZ 5360/5392/5387) 3966 1.1 jruoho 3967 1.1 jruoho Fixed a problem where the AE_BUFFER_LIMIT exception was returned instead of 3968 1.1 jruoho AE_STRING_LIMIT on an out-of-bounds Index() operation. (Valery Podrezov, BZ 3969 1.1 jruoho 5480) 3970 1.1 jruoho 3971 1.1 jruoho Implemented a memory cleanup at the end of the execution of each iteration 3972 1.1 jruoho of an AML While() loop, preventing the accumulation of outstanding objects. 3973 1.1 jruoho (Valery Podrezov, BZ 5427) 3974 1.1 jruoho 3975 1.1 jruoho Eliminated a chunk of duplicate code in the object resolution code. (Valery 3976 1.1 jruoho Podrezov, BZ 5336) 3977 1.1 jruoho 3978 1.1 jruoho Fixed several warnings during the 64-bit code generation. 3979 1.1 jruoho 3980 1.1 jruoho The AcpiSrc source code conversion tool now inserts one line of whitespace 3981 1.1 jruoho after an if() statement that is followed immediately by a comment, improving 3982 1.1 jruoho readability of the Linux code. 3983 1.1 jruoho 3984 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 3985 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 3986 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 3987 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 3988 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 3989 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 3990 1.1 jruoho of the compiler and the compiler options used during generation. 3991 1.1 jruoho 3992 1.1 jruoho Previous Release: 3993 1.1 jruoho Non-Debug Version: 81.0K Code, 17.9K Data, 98.9K Total 3994 1.1 jruoho Debug Version: 161.3K Code, 65.7K Data, 227.0K Total 3995 1.1 jruoho Current Release: 3996 1.1 jruoho Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 3997 1.1 jruoho Debug Version: 161.3K Code, 65.6K Data, 226.9K Total 3998 1.1 jruoho 3999 1.1 jruoho 4000 1.1 jruoho 2) iASL Compiler/Disassembler: 4001 1.1 jruoho 4002 1.1 jruoho Fixed a problem with the disassembly of a BankField operator with a complex 4003 1.1 jruoho expression for the BankValue parameter. 4004 1.1 jruoho 4005 1.1 jruoho ---------------------------------------- 4006 1.1 jruoho 27 January 2006. Summary of changes for version 20060127: 4007 1.1 jruoho 4008 1.1 jruoho 1) ACPI CA Core Subsystem: 4009 1.1 jruoho 4010 1.1 jruoho Implemented support in the Resource Manager to allow unresolved namestring 4011 1.1 jruoho references within resource package objects for the _PRT method. This support 4012 1.1 jruoho is in addition to the previously implemented unresolved reference support 4013 1.1 jruoho within the AML parser. If the interpreter slack mode is enabled, these 4014 1.1 jruoho unresolved references will be passed through to the caller as a NULL package 4015 1.1 jruoho entry. 4016 1.1 jruoho 4017 1.1 jruoho Implemented and deployed new macros and functions for error and warning 4018 1.1 jruoho messages across the subsystem. These macros are simpler and generate less 4019 1.1 jruoho code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, 4020 1.1 jruoho ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older 4021 1.1 jruoho macros remain defined to allow ACPI drivers time to migrate to the new 4022 1.1 jruoho macros. 4023 1.1 jruoho 4024 1.1 jruoho Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of the 4025 1.1 jruoho Acquire/Release Lock OSL interfaces. 4026 1.1 jruoho 4027 1.1 jruoho Fixed a problem where Alias ASL operators are sometimes not correctly 4028 1.1 jruoho resolved, in both the interpreter and the iASL compiler. 4029 1.1 jruoho 4030 1.1 jruoho Fixed several problems with the implementation of the ConcatenateResTemplate 4031 1.1 jruoho ASL operator. As per the ACPI specification, zero length buffers are now 4032 1.1 jruoho treated as a single EndTag. One-length buffers always cause a fatal 4033 1.1 jruoho exception. Non-zero length buffers that do not end with a full 2-byte EndTag 4034 1.1 jruoho cause a fatal exception. 4035 1.1 jruoho 4036 1.1 jruoho Fixed a possible structure overwrite in the AcpiGetObjectInfo external 4037 1.1 jruoho interface. (With assistance from Thomas Renninger) 4038 1.1 jruoho 4039 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4040 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4041 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4042 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4043 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4044 1.1 jruoho and data size.

Summary of changes for version 20060113: 4062 1.1 jruoho 4063 1.1 jruoho 1) ACPI CA Core Subsystem: 4064 1.1 jruoho 4065 1.1 jruoho Added 2006 copyright to all module headers and signons. This affects 4066 1.1 jruoho virtually every file in the ACPICA core subsystem, iASL compiler, and the 4067 1.1 jruoho utilities. 4068 1.1 jruoho 4069 1.1 jruoho Enhanced the ACPICA error reporting in order to simplify user migration to 4070 1.1 jruoho the non-debug version of ACPICA. Replaced all instances of the 4071 1.1 jruoho ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug 4072 1.1 jruoho levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, 4073 1.1 jruoho respectively. This preserves all error and warning messages in the non-debug 4074 1.1 jruoho version of the ACPICA code (this has been referred to as the "debug lite" 4075 1.1 jruoho option.) Over 200 cases were converted to create a total of over 380 4076 1.1 jruoho error/warning messages across the ACPICA code. This increases the code and 4077 1.1 jruoho data size of the default non-debug version of the code somewhat (about 13K), 4078 1.1 jruoho but all error/warning reporting may be disabled if desired (and code 4079 1.1 jruoho eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time 4080 1.1 jruoho configuration option. The size of the debug version of ACPICA remains about 4081 1.1 jruoho the same. 4082 1.1 jruoho 4083 1.1 jruoho Fixed a memory leak within the AML Debugger "Set" command. One object was 4084 1.1 jruoho not properly deleted for every successful invocation of the command. 4085 1.1 jruoho 4086 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4087 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4088 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4089 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4090 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4091 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4092 1.1 jruoho of the compiler and the compiler options used during generation. 4093 1.1 jruoho 4094 1.1 jruoho Previous Release: 4095 1.1 jruoho Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total 4096 1.1 jruoho Debug Version: 163.7K Code, 67.5K Data, 231.2K Total 4097 1.1 jruoho Current Release: 4098 1.1 jruoho Non-Debug Version: 83.1K Code, 18.4K Data, 101.5K Total 4099 1.1 jruoho Debug Version: 163.2K Code, 66.2K Data, 229.4K Total 4100 1.1 jruoho 4101 1.1 jruoho 4102 1.1 jruoho 2) iASL Compiler/Disassembler: 4103 1.1 jruoho 4104 1.1 jruoho The compiler now officially supports the ACPI 3.0a specification that was 4105 1.1 jruoho released on December 30, 2005.

Summary of changes for version 20051216: 4109 1.1 jruoho 4110 1.1 jruoho 1) ACPI CA Core Subsystem: 4111 1.1 jruoho 4112 1.1 jruoho Implemented optional support to allow unresolved names within ASL Package 4113 1.1 jruoho objects. A null object is inserted in the package when a named reference 4114 1.1 jruoho cannot be located in the current namespace. Enabled via the interpreter 4115 1.1 jruoho slack flag, this should eliminate AE_NOT_FOUND exceptions seen on machines 4116 1.1 jruoho that contain such code. 4117 1.1 jruoho 4118 1.1 jruoho Implemented an optimization to the initialization sequence that can improve 4119 1.1 jruoho boot time. During ACPI device initialization, the _STA method is now run if 4120 1.1 jruoho and only if the _INI method exists. The _STA method is used to determine if 4121 1.1 jruoho the device is present; An _INI can only be run if _STA returns present, but 4122 1.1 jruoho it is a waste of time to run the _STA method if the _INI does not exist. 4123 1.1 jruoho (Prototype and assistance from Dong Wei) 4124 1.1 jruoho 4125 1.1 jruoho Implemented use of the C99 uintptr_t for the pointer casting macros if it is 4126 1.1 jruoho available in the current compiler. Otherwise, the default (void *) cast is 4127 1.1 jruoho used as before. 4128 1.1 jruoho 4129 1.1 jruoho Fixed some possible memory leaks found within the execution path of the 4130 1.1 jruoho Break, Continue, If, and CreateField operators. (Valery Podrezov) 4131 1.1 jruoho 4132 1.1 jruoho Fixed a problem introduced in the 20051202 release where an exception is 4133 1.1 jruoho generated during method execution if a control method attempts to declare 4134 1.1 jruoho another method. 4135 1.1 jruoho 4136 1.1 jruoho Moved resource descriptor string constants that are used by both the AML 4137 1.1 jruoho disassembler and AML debugger to the common utilities directory so that 4138 1.1 jruoho these components are independent. 4139 1.1 jruoho 4140 1.1 jruoho Implemented support in the AcpiExec utility (-e switch) to globally ignore 4141 1.1 jruoho exceptions during control method execution (method is not aborted.) 4142 1.1 jruoho 4143 1.1 jruoho Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix 4144 1.1 jruoho generation. 4145 1.1 jruoho 4146 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4147 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4148 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4149 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4150 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4151 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4152 1.1 jruoho of the compiler and the compiler options used during generation. 4153 1.1 jruoho 4154 1.1 jruoho Previous Release: 4155 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4156 1.1 jruoho Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 4157 1.1 jruoho Current Release: 4158 1.1 jruoho Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total 4159 1.1 jruoho Debug Version: 163.7K Code, 67.5K Data, 231.2K Total 4160 1.1 jruoho 4161 1.1 jruoho 4162 1.1 jruoho 2) iASL Compiler/Disassembler: 4163 1.1 jruoho 4164 1.1 jruoho Fixed a problem where a CPU stack overflow fault could occur if a recursive 4165 1.1 jruoho method call was made from within a Return statement. 4166 1.1 jruoho 4167 1.1 jruoho ---------------------------------------- 4168 1.1 jruoho 02 December 2005. Summary of changes for version 20051202: 4169 1.1 jruoho 4170 1.1 jruoho 1) ACPI CA Core Subsystem: 4171 1.1 jruoho 4172 1.1 jruoho Modified the parsing of control methods to no longer create namespace 4173 1.1 jruoho objects during the first pass of the parse. Objects are now created only 4174 1.1 jruoho during the execute phase, at the moment the namespace creation operator is 4175 1.1 jruoho encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This 4176 1.1 jruoho should eliminate ALREADY_EXISTS exceptions seen on some machines where 4177 1.1 jruoho reentrant control methods are protected by an AML mutex. The mutex will now 4178 1.1 jruoho correctly block multiple threads from attempting to create the same object 4179 1.1 jruoho more than once. 4180 1.1 jruoho 4181 1.1 jruoho Increased the number of available Owner Ids for namespace object tracking 4182 1.1 jruoho from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on 4183 1.1 jruoho some machines with a large number of ACPI tables (either static or dynamic). 4184 1.1 jruoho 4185 1.1 jruoho Fixed a problem with the AcpiExec utility where a fault could occur when the 4186 1.1 jruoho -b switch (batch mode) is used. 4187 1.1 jruoho 4188 1.1 jruoho Enhanced the namespace dump routine to output the owner ID for each 4189 1.1 jruoho namespace object. 4190 1.1 jruoho 4191 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4192 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4193 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4194 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4195 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4196 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4197 1.1 jruoho of the compiler and the compiler options used during generation. 4198 1.1 jruoho 4199 1.1 jruoho Previous Release: 4200 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4201 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4202 1.1 jruoho Current Release: 4203 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4204 1.1 jruoho Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 4205 1.1 jruoho 4206 1.1 jruoho 4207 1.1 jruoho 2) iASL Compiler/Disassembler: 4208 1.1 jruoho 4209 1.1 jruoho Fixed a parse error during compilation of certain Switch/Case constructs. To 4210 1.1 jruoho simplify the parse, the grammar now allows for multiple Default statements 4211 1.1 jruoho and this error is now detected and flagged during the analysis phase. 4212 1.1 jruoho 4213 1.1 jruoho Disassembler: The disassembly now includes the contents of the original 4214 1.1 jruoho table header within a comment at the start of the file. This includes the 4215 1.1 jruoho name and version of the original ASL compiler. 4216 1.1 jruoho 4217 1.1 jruoho ---------------------------------------- 4218 1.1 jruoho 17 November 2005. Summary of changes for version 20051117: 4219 1.1 jruoho 4220 1.1 jruoho 1) ACPI CA Core Subsystem: 4221 1.1 jruoho 4222 1.1 jruoho Fixed a problem in the AML parser where the method thread count could be 4223 1.1 jruoho decremented below zero if any errors occurred during the method parse phase. 4224 1.1 jruoho This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. 4225 1.1 jruoho This also fixed a related regression with the mechanism that detects and 4226 1.1 jruoho corrects methods that cannot properly handle reentrancy (related to the 4227 1.1 jruoho deployment of the new OwnerId mechanism.) 4228 1.1 jruoho 4229 1.1 jruoho Eliminated the pre-parsing of control methods (to detect errors) during 4230 1.1 jruoho table load. Related to the problem above, this was causing unwind issues if 4231 1.1 jruoho any errors occurred during the parse, and it seemed to be overkill. A table 4232 1.1 jruoho load should not be aborted if there are problems with any single control 4233 1.1 jruoho method, thus rendering this feature rather pointless. 4234 1.1 jruoho 4235 1.1 jruoho Fixed a problem with the new table-driven resource manager where an internal 4236 1.1 jruoho buffer overflow could occur for small resource templates. 4237 1.1 jruoho 4238 1.1 jruoho Implemented a new external interface, AcpiGetVendorResource. This interface 4239 1.1 jruoho will find and return a vendor-defined resource descriptor within a _CRS or 4240 1.1 jruoho _PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn Helgaas. 4241 1.1 jruoho 4242 1.1 jruoho Removed the length limit (200) on string objects as per the upcoming ACPI 4243 1.1 jruoho 3.0A specification. This affects the following areas of the interpreter: 1) 4244 1.1 jruoho any implicit conversion of a Buffer to a String, 2) a String object result 4245 1.1 jruoho of the ASL Concatentate operator, 3) the String object result of the ASL 4246 1.1 jruoho ToString operator. 4247 1.1 jruoho 4248 1.1 jruoho Fixed a problem in the Windows OS interface layer (OSL) where a WAIT_FOREVER 4249 1.1 jruoho on a semaphore object would incorrectly timeout. This allows the 4250 1.1 jruoho multithreading features of the AcpiExec utility to work properly under 4251 1.1 jruoho Windows. 4252 1.1 jruoho 4253 1.1 jruoho Updated the Linux makefiles for the iASL compiler and AcpiExec to include 4254 1.1 jruoho the recently added file named "utresrc.c". 4255 1.1 jruoho 4256 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4257 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4258 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4259 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4260 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4261 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4262 1.1 jruoho of the compiler and the compiler options used during generation. 4263 1.1 jruoho 4264 1.1 jruoho Previous Release: 4265 1.1 jruoho Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 4266 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4267 1.1 jruoho Current Release: 4268 1.1 jruoho Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4269 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4270 1.1 jruoho 4271 1.1 jruoho 4272 1.1 jruoho 2) iASL Compiler/Disassembler: 4273 1.1 jruoho 4274 1.1 jruoho Removed the limit (200) on string objects as per the upcoming ACPI 3.0A 4275 1.1 jruoho specification. For the iASL compiler, this means that string literals within 4276 1.1 jruoho the source ASL can be of any length. 4277 1.1 jruoho 4278 1.1 jruoho Enhanced the listing output to dump the AML code for resource descriptors 4279 1.1 jruoho immediately after the ASL code for each descriptor, instead of in a block at 4280 1.1 jruoho the end of the entire resource template. 4281 1.1 jruoho 4282 1.1 jruoho Enhanced the compiler debug output to dump the entire original parse tree 4283 1.1 jruoho constructed during the parse phase, before any transforms are applied to the 4284 1.1 jruoho tree. The transformed tree is dumped also. 4285 1.1 jruoho 4286 1.1 jruoho ---------------------------------------- 4287 1.1 jruoho 02 November 2005. Summary of changes for version 20051102: 4288 1.1 jruoho 4289 1.1 jruoho 1) ACPI CA Core Subsystem: 4290 1.1 jruoho 4291 1.1 jruoho Modified the subsystem initialization sequence to improve GPE support. The 4292 1.1 jruoho GPE initialization has been split into two parts in order to defer execution 4293 1.1 jruoho of the _PRW methods (Power Resources for Wake) until after the hardware is 4294 1.1 jruoho fully initialized and the SCI handler is installed. This allows the _PRW 4295 1.1 jruoho methods to access fields protected by the Global Lock. This will fix systems 4296 1.1 jruoho where a NO_GLOBAL_LOCK exception has been seen during initialization. 4297 1.1 jruoho 4298 1.1 jruoho Converted the ACPI internal object disassemble and display code within the 4299 1.1 jruoho AML debugger to fully table-driven operation, reducing code size and 4300 1.1 jruoho increasing maintainability. 4301 1.1 jruoho 4302 1.1 jruoho Fixed a regression with the ConcatenateResTemplate() ASL operator introduced 4303 1.1 jruoho in the 20051021 release. 4304 1.1 jruoho 4305 1.1 jruoho Implemented support for "local" internal ACPI object types within the 4306 1.1 jruoho debugger "Object" command and the AcpiWalkNamespace external interfaces. 4307 1.1 jruoho These local types include RegionFields, BankFields, IndexFields, Alias, and 4308 1.1 jruoho reference objects. 4309 1.1 jruoho 4310 1.1 jruoho Moved common AML resource handling code into a new file, "utresrc.c". This 4311 1.1 jruoho code is shared by both the Resource Manager and the AML Debugger. 4312 1.1 jruoho 4313 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4314 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4315 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4316 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4317 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4318 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4319 1.1 jruoho of the compiler and the compiler options used during generation. 4320 1.1 jruoho 4321 1.1 jruoho Previous Release: 4322 1.1 jruoho Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 4323 1.1 jruoho Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 4324 1.1 jruoho Current Release: 4325 1.1 jruoho Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 4326 1.1 jruoho Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4327 1.1 jruoho 4328 1.1 jruoho 4329 1.1 jruoho 2) iASL Compiler/Disassembler: 4330 1.1 jruoho 4331 1.1 jruoho Fixed a problem with very large initializer lists (more than 4000 elements) 4332 1.1 jruoho for both Buffer and Package objects where the parse stack could overflow. 4333 1.1 jruoho 4334 1.1 jruoho Enhanced the pre-compile source code scan for non-ASCII characters to ignore 4335 1.1 jruoho characters within comment fields. The scan is now always performed and is no 4336 1.1 jruoho longer optional, detecting invalid characters within a source file 4337 1.1 jruoho immediately rather than during the parse phase or later. 4338 1.1 jruoho 4339 1.1 jruoho Enhanced the ASL grammar definition to force early reductions on all list- 4340 1.1 jruoho style grammar elements so that the overall parse stack usage is greatly 4341 1.1 jruoho reduced. This should improve performance and reduce the possibility of parse 4342 1.1 jruoho stack overflow. 4343 1.1 jruoho 4344 1.1 jruoho Eliminated all reduce/reduce conflicts in the iASL parser generation. Also, 4345 1.1 jruoho with the addition of a %expected statement, the compiler generates from 4346 1.1 jruoho source with no warnings. 4347 1.1 jruoho 4348 1.1 jruoho Fixed a possible segment fault in the disassembler if the input filename 4349 1.1 jruoho does not contain a "dot" extension (Thomas Renninger). 4350 1.1 jruoho 4351 1.1 jruoho ---------------------------------------- 4352 1.1 jruoho 21 October 2005. Summary of changes for version 20051021: 4353 1.1 jruoho 4354 1.1 jruoho 1) ACPI CA Core Subsystem: 4355 1.1 jruoho 4356 1.1 jruoho Implemented support for the EM64T and other x86-64 processors. This 4357 1.1 jruoho essentially entails recognizing that these processors support non-aligned 4358 1.1 jruoho memory transfers. Previously, all 64-bit processors were assumed to lack 4359 1.1 jruoho hardware support for non-aligned transfers. 4360 1.1 jruoho 4361 1.1 jruoho Completed conversion of the Resource Manager to nearly full table-driven 4362 1.1 jruoho operation. Specifically, the resource conversion code (convert AML to 4363 1.1 jruoho internal format and the reverse) and the debug code to dump internal 4364 1.1 jruoho resource descriptors are fully table-driven, reducing code and data size and 4365 1.1 jruoho improving maintainability. 4366 1.1 jruoho 4367 1.1 jruoho The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word 4368 1.1 jruoho on 64-bit processors instead of a fixed 32-bit word. (With assistance from 4369 1.1 jruoho Alexey Starikovskiy) 4370 1.1 jruoho 4371 1.1 jruoho Implemented support within the resource conversion code for the Type- 4372 1.1 jruoho Specific byte within the various ACPI 3.0 *WordSpace macros. 4373 1.1 jruoho 4374 1.1 jruoho Fixed some issues within the resource conversion code for the type-specific 4375 1.1 jruoho flags for both Memory and I/O address resource descriptors. For Memory, 4376 1.1 jruoho implemented support for the MTP and TTP flags. For I/O, split the TRS and 4377 1.1 jruoho TTP flags into two separate fields. 4378 1.1 jruoho 4379 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4380 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4381 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4382 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4383 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4384 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4385 1.1 jruoho of the compiler and the compiler options used during generation. 4386 1.1 jruoho 4387 1.1 jruoho Previous Release: 4388 1.1 jruoho Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total 4389 1.1 jruoho Debug Version: 168.0K Code, 68.3K Data, 236.3K Total 4390 1.1 jruoho Current Release: 4391 1.1 jruoho Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 4392 1.1 jruoho Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 4393 1.1 jruoho 4394 1.1 jruoho 4395 1.1 jruoho 4396 1.1 jruoho 2) iASL Compiler/Disassembler: 4397 1.1 jruoho 4398 1.1 jruoho Relaxed a compiler restriction that disallowed a ResourceIndex byte if the 4399 1.1 jruoho corresponding ResourceSource string was not also present in a resource 4400 1.1 jruoho descriptor declaration. This restriction caused problems with existing 4401 1.1 jruoho AML/ASL code that includes the Index byte without the string. When such AML 4402 1.1 jruoho was disassembled, it could not be compiled without modification. Further, 4403 1.1 jruoho the modified code created a resource template with a different size than the 4404 1.1 jruoho original, breaking code that used fixed offsets into the resource template 4405 1.1 jruoho buffer. 4406 1.1 jruoho 4407 1.1 jruoho Removed a recent feature of the disassembler to ignore a lone ResourceIndex 4408 1.1 jruoho byte. This byte is now emitted if present so that the exact AML can be 4409 1.1 jruoho reproduced when the disassembled code is recompiled. 4410 1.1 jruoho 4411 1.1 jruoho Improved comments and text alignment for the resource descriptor code 4412 1.1 jruoho emitted by the disassembler. 4413 1.1 jruoho 4414 1.1 jruoho Implemented disassembler support for the ACPI 3.0 AccessSize field within a 4415 1.1 jruoho Register() resource descriptor. 4416 1.1 jruoho 4417 1.1 jruoho ---------------------------------------- 4418 1.1 jruoho 30 September 2005. Summary of changes for version 20050930: 4419 1.1 jruoho 4420 1.1 jruoho 1) ACPI CA Core Subsystem: 4421 1.1 jruoho 4422 1.1 jruoho Completed a major overhaul of the Resource Manager code - specifically, 4423 1.1 jruoho optimizations in the area of the AML/internal resource conversion code. The 4424 1.1 jruoho code has been optimized to simplify and eliminate duplicated code, CPU stack 4425 1.1 jruoho use has been decreased by optimizing function parameters and local 4426 1.1 jruoho variables, and naming conventions across the manager have been standardized 4427 1.1 jruoho for clarity and ease of maintenance (this includes function, parameter, 4428 1.1 jruoho variable, and struct/typedef names.) The update may force changes in some 4429 1.1 jruoho driver code, depending on how resources are handled by the host OS. 4430 1.1 jruoho 4431 1.1 jruoho All Resource Manager dispatch and information tables have been moved to a 4432 1.1 jruoho single location for clarity and ease of maintenance. One new file was 4433 1.1 jruoho created, named "rsinfo.c". 4434 1.1 jruoho 4435 1.1 jruoho The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to 4436 1.1 jruoho guarantee that the argument is not evaluated twice, making them less prone 4437 1.1 jruoho to macro side-effects. However, since there exists the possibility of 4438 1.1 jruoho additional stack use if a particular compiler cannot optimize them (such as 4439 1.1 jruoho in the debug generation case), the original macros are optionally available. 4440 1.1 jruoho Note that some invocations of the return_VALUE macro may now cause size 4441 1.1 jruoho mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to 4442 1.1 jruoho eliminate these. (From Randy Dunlap) 4443 1.1 jruoho 4444 1.1 jruoho Implemented a new mechanism to enable debug tracing for individual control 4445 1.1 jruoho methods. A new external interface, AcpiDebugTrace, is provided to enable 4446 1.1 jruoho this mechanism. The intent is to allow the host OS to easily enable and 4447 1.1 jruoho disable tracing for problematic control methods. This interface can be 4448 1.1 jruoho easily exposed to a user or debugger interface if desired. See the file 4449 1.1 jruoho psxface.c for details. 4450 1.1 jruoho 4451 1.1 jruoho AcpiUtCallocate will now return a valid pointer if a length of zero is 4452 1.1 jruoho specified - a length of one is used and a warning is issued. This matches 4453 1.1 jruoho the behavior of AcpiUtAllocate. 4454 1.1 jruoho 4455 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4456 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4457 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4458 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4459 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4460 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4461 1.1 jruoho of the compiler and the compiler options used during generation. 4462 1.1 jruoho 4463 1.1 jruoho Previous Release: 4464 1.1 jruoho Non-Debug Version: 77.5K Code, 12.0K Data, 89.5K Total 4465 1.1 jruoho Debug Version: 168.1K Code, 68.4K Data, 236.5K Total 4466 1.1 jruoho Current Release: 4467 1.1 jruoho Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total 4468 1.1 jruoho Debug Version: 168.0K Code, 68.3K Data, 236.3K Total 4469 1.1 jruoho 4470 1.1 jruoho 4471 1.1 jruoho 2) iASL Compiler/Disassembler: 4472 1.1 jruoho 4473 1.1 jruoho A remark is issued if the effective compile-time length of a package or 4474 1.1 jruoho buffer is zero. Previously, this was a warning. 4475 1.1 jruoho 4476 1.1 jruoho ---------------------------------------- 4477 1.1 jruoho 16 September 2005. Summary of changes for version 20050916: 4478 1.1 jruoho 4479 1.1 jruoho 1) ACPI CA Core Subsystem: 4480 1.1 jruoho 4481 1.1 jruoho Fixed a problem within the Resource Manager where support for the Generic 4482 1.1 jruoho Register descriptor was not fully implemented. This descriptor is now fully 4483 1.1 jruoho recognized, parsed, disassembled, and displayed. 4484 1.1 jruoho 4485 1.1 jruoho Completely restructured the Resource Manager code to utilize table-driven 4486 1.1 jruoho dispatch and lookup, eliminating many of the large switch() statements. This 4487 1.1 jruoho reduces overall subsystem code size and code complexity. Affects the 4488 1.1 jruoho resource parsing and construction, disassembly, and debug dump output. 4489 1.1 jruoho 4490 1.1 jruoho Cleaned up and restructured the debug dump output for all resource 4491 1.1 jruoho descriptors. Improved readability of the output and reduced code size. 4492 1.1 jruoho 4493 1.1 jruoho Fixed a problem where changes to internal data structures caused the 4494 1.1 jruoho optional ACPI_MUTEX_DEBUG code to fail compilation if specified. 4495 1.1 jruoho 4496 1.1 jruoho Code and Data Size: The current and previous library sizes for the core 4497 1.1 jruoho subsystem are shown below. These are the code and data sizes for the 4498 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4499 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug version of the 4500 1.1 jruoho code includes the debug output trace mechanism and has a much larger code 4501 1.1 jruoho and data size. Note that these values will vary depending on the efficiency 4502 1.1 jruoho of the compiler and the compiler options used during generation. 4503 1.1 jruoho 4504 1.1 jruoho Previous Release: 4505 1.1 jruoho Non-Debug Version: 78.4K Code, 11.8K Data, 90.2K Total 4506 1.1 jruoho Debug Version: 169.6K Code, 69.9K Data, 239.5K Total 4507 1.1 jruoho Current Release: 4508 1.1 jruoho Non-Debug Version: 77.5K Code, 12.0K Data, 89.5K Total 4509 1.1 jruoho Debug Version: 168.1K Code, 68.4K Data, 236.5K Total 4510 1.1 jruoho 4511 1.1 jruoho 4512 1.1 jruoho 2) iASL Compiler/Disassembler: 4513 1.1 jruoho 4514 1.1 jruoho Updated the disassembler to automatically insert an EndDependentFn() macro 4515 1.1 jruoho into the ASL stream if this macro is missing in the original AML code, 4516 1.1 jruoho simplifying compilation of the resulting ASL module. 4517 1.1 jruoho 4518 1.1 jruoho Fixed a problem in the disassembler where a disassembled ResourceSource 4519 1.1 jruoho string (within a large resource descriptor) was not surrounded by quotes and 4520 1.1 jruoho not followed by a comma, causing errors when the resulting ASL module was 4521 1.1 jruoho compiled. Also, escape sequences within a ResourceSource string are now 4522 1.1 jruoho handled correctly (especially "\\") 4523 1.1 jruoho 4524 1.1 jruoho ---------------------------------------- 4525 1.1 jruoho 02 September 2005. Summary of changes for version 20050902: 4526 1.1 jruoho 4527 1.1 jruoho 1) ACPI CA Core Subsystem: 4528 1.1 jruoho 4529 1.1 jruoho Fixed a problem with the internal Owner ID allocation and deallocation 4530 1.1 jruoho mechanisms for control method execution and recursive method invocation. 4531 1.1 jruoho This should eliminate the OWNER_ID_LIMIT exceptions and "Invalid OwnerId" 4532 1.1 jruoho messages seen on some systems. Recursive method invocation depth is 4533 1.1 jruoho currently limited to 255. (Alexey Starikovskiy) 4534 1.1 jruoho 4535 1.1 jruoho Completely eliminated all vestiges of support for the "module-level 4536 1.1 jruoho executable code" until this support is fully implemented and debugged. This 4537 1.1 jruoho should eliminate the NO_RETURN_VALUE exceptions seen during table load on 4538 1.1 jruoho some systems that invoke this support. 4539 1.1 jruoho 4540 1.1 jruoho Fixed a problem within the resource manager code where the transaction flags 4541 1.1 jruoho for a 64-bit address descriptor were handled incorrectly in the type- 4542 1.1 jruoho specific flag byte. 4543 1.1 jruoho 4544 1.1 jruoho Consolidated duplicate code within the address descriptor resource manager 4545 1.1 jruoho code, reducing overall subsystem code size. 4546 1.1 jruoho 4547 1.1 jruoho Fixed a fault when using the AML debugger "disassemble" command to 4548 1.1 jruoho disassemble individual control methods. 4549 1.1 jruoho 4550 1.1 jruoho Removed references to the "release_current" directory within the Unix 4551 1.1 jruoho release package. 4552 1.1 jruoho 4553 1.1 jruoho Code and Data Size: The current and previous core subsystem library sizes 4554 1.1 jruoho are shown below. These are the code and data sizes for the acpica.lib 4555 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler. These values do not 4556 1.1 jruoho include any ACPI driver or OSPM code. The debug version of the code includes 4557 1.1 jruoho the debug output trace mechanism and has a much larger code and data size. 4558 1.1 jruoho Note that these values will vary depending on the efficiency of the compiler 4559 1.1 jruoho and the compiler options used during generation. 4560 1.1 jruoho 4561 1.1 jruoho Previous Release: 4562 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 4563 1.1 jruoho Debug Version: 170.0K Code, 69.9K Data, 239.9K Total 4564 1.1 jruoho Current Release: 4565 1.1 jruoho Non-Debug Version: 78.4K Code, 11.8K Data, 90.2K Total 4566 1.1 jruoho Debug Version: 169.6K Code, 69.9K Data, 239.5K Total 4567 1.1 jruoho 4568 1.1 jruoho 4569 1.1 jruoho 2) iASL Compiler/Disassembler: 4570 1.1 jruoho 4571 1.1 jruoho Implemented an error check for illegal duplicate values in the interrupt and 4572 1.1 jruoho dma lists for the following ASL macros: Dma(), Irq(), IrqNoFlags(), and 4573 1.1 jruoho Interrupt(). 4574 1.1 jruoho 4575 1.1 jruoho Implemented error checking for the Irq() and IrqNoFlags() macros to detect 4576 1.1 jruoho too many values in the interrupt list (16 max) and invalid values in the 4577 1.1 jruoho list (range 0 - 15) 4578 1.1 jruoho 4579 1.1 jruoho The maximum length string literal within an ASL file is now restricted to 4580 1.1 jruoho 200 characters as per the ACPI specification. 4581 1.1 jruoho 4582 1.1 jruoho Fixed a fault when using the -ln option (generate namespace listing). 4583 1.1 jruoho 4584 1.1 jruoho Implemented an error check to determine if a DescriptorName within a 4585 1.1 jruoho resource descriptor has already been used within the current scope. 4586 1.1 jruoho 4587 1.1 jruoho ---------------------------------------- 4588 1.1 jruoho 15 August 2005. Summary of changes for version 20050815: 4589 1.1 jruoho 4590 1.1 jruoho 1) ACPI CA Core Subsystem: 4591 1.1 jruoho 4592 1.1 jruoho Implemented a full bytewise compare to determine if a table load request is 4593 1.1 jruoho attempting to load a duplicate table. The compare is performed if the table 4594 1.1 jruoho signatures and table lengths match. This will allow different tables with 4595 1.1 jruoho the same OEM Table ID and revision to be loaded - probably against the ACPI 4596 1.1 jruoho specification, but discovered in the field nonetheless. 4597 1.1 jruoho 4598 1.1 jruoho Added the changes.txt logfile to each of the zipped release packages. 4599 1.1 jruoho 4600 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4601 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4602 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4603 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4604 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4605 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4606 1.1 jruoho the compiler options used during generation. 4607 1.1 jruoho 4608 1.1 jruoho Previous Release: 4609 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 4610 1.1 jruoho Debug Version: 167.0K Code, 69.9K Data, 236.9K Total 4611 1.1 jruoho Current Release: 4612 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 4613 1.1 jruoho Debug Version: 170.0K Code, 69.9K Data, 239.9K Total 4614 1.1 jruoho 4615 1.1 jruoho 4616 1.1 jruoho 2) iASL Compiler/Disassembler: 4617 1.1 jruoho 4618 1.1 jruoho Fixed a problem where incorrect AML code could be generated for Package 4619 1.1 jruoho objects if optimization is disabled (via the -oa switch). 4620 1.1 jruoho 4621 1.1 jruoho Fixed a problem with where incorrect AML code is generated for variable- 4622 1.1 jruoho length packages when the package length is not specified and the number of 4623 1.1 jruoho initializer values is greater than 255. 4624 1.1 jruoho 4625 1.1 jruoho 4626 1.1 jruoho ---------------------------------------- 4627 1.1 jruoho 29 July 2005. Summary of changes for version 20050729: 4628 1.1 jruoho 4629 1.1 jruoho 1) ACPI CA Core Subsystem: 4630 1.1 jruoho 4631 1.1 jruoho Implemented support to ignore an attempt to install/load a particular ACPI 4632 1.1 jruoho table more than once. Apparently there exists BIOS code that repeatedly 4633 1.1 jruoho attempts to load the same SSDT upon certain events. With assistance from 4634 1.1 jruoho Venkatesh Pallipadi. 4635 1.1 jruoho 4636 1.1 jruoho Restructured the main interface to the AML parser in order to correctly 4637 1.1 jruoho handle all exceptional conditions. This will prevent leakage of the OwnerId 4638 1.1 jruoho resource and should eliminate the AE_OWNER_ID_LIMIT exceptions seen on some 4639 1.1 jruoho machines. With assistance from Alexey Starikovskiy. 4640 1.1 jruoho 4641 1.1 jruoho Support for "module level code" has been disabled in this version due to a 4642 1.1 jruoho number of issues that have appeared on various machines. The support can be 4643 1.1 jruoho enabled by defining ACPI_ENABLE_MODULE_LEVEL_CODE during subsystem 4644 1.1 jruoho compilation. When the issues are fully resolved, the code will be enabled by 4645 1.1 jruoho default again. 4646 1.1 jruoho 4647 1.1 jruoho Modified the internal functions for debug print support to define the 4648 1.1 jruoho FunctionName parameter as a (const char *) for compatibility with compiler 4649 1.1 jruoho built-in macros such as __FUNCTION__, etc. 4650 1.1 jruoho 4651 1.1 jruoho Linted the entire ACPICA source tree for both 32-bit and 64-bit. 4652 1.1 jruoho 4653 1.1 jruoho Implemented support to display an object count summary for the AML Debugger 4654 1.1 jruoho commands Object and Methods. 4655 1.1 jruoho 4656 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4657 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4658 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4659 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4660 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4661 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4662 1.1 jruoho the compiler options used during generation. 4663 1.1 jruoho 4664 1.1 jruoho Previous Release: 4665 1.1 jruoho Non-Debug Version: 78.6K Code, 11.6K Data, 90.2K Total 4666 1.1 jruoho Debug Version: 170.0K Code, 69.7K Data, 239.7K Total 4667 1.1 jruoho Current Release: 4668 1.1 jruoho Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 4669 1.1 jruoho Debug Version: 167.0K Code, 69.9K Data, 236.9K Total 4670 1.1 jruoho 4671 1.1 jruoho 4672 1.1 jruoho 2) iASL Compiler/Disassembler: 4673 1.1 jruoho 4674 1.1 jruoho Fixed a regression that appeared in the 20050708 version of the compiler 4675 1.1 jruoho where an error message was inadvertently emitted for invocations of the _OSI 4676 1.1 jruoho reserved control method. 4677 1.1 jruoho 4678 1.1 jruoho ---------------------------------------- 4679 1.1 jruoho 08 July 2005. Summary of changes for version 20050708: 4680 1.1 jruoho 4681 1.1 jruoho 1) ACPI CA Core Subsystem: 4682 1.1 jruoho 4683 1.1 jruoho The use of the CPU stack in the debug version of the subsystem has been 4684 1.1 jruoho considerably reduced. Previously, a debug structure was declared in every 4685 1.1 jruoho function that used the debug macros. This structure has been removed in 4686 1.1 jruoho favor of declaring the individual elements as parameters to the debug 4687 1.1 jruoho functions. This reduces the cumulative stack use during nested execution of 4688 1.1 jruoho ACPI function calls at the cost of a small increase in the code size of the 4689 1.1 jruoho debug version of the subsystem. With assistance from Alexey Starikovskiy and 4690 1.1 jruoho Len Brown. 4691 1.1 jruoho 4692 1.1 jruoho Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent 4693 1.1 jruoho headers to define a macro that will return the current function name at 4694 1.1 jruoho runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by 4695 1.1 jruoho the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the 4696 1.1 jruoho compiler-dependent header, the function name is saved on the CPU stack (one 4697 1.1 jruoho pointer per function.) This mechanism is used because apparently there 4698 1.1 jruoho exists no standard ANSI-C defined macro that that returns the function name. 4699 1.1 jruoho 4700 1.1 jruoho Redesigned and reimplemented the "Owner ID" mechanism used to track 4701 1.1 jruoho namespace objects created/deleted by ACPI tables and control method 4702 1.1 jruoho execution. A bitmap is now used to allocate and free the IDs, thus solving 4703 1.1 jruoho the wraparound problem present in the previous implementation. The size of 4704 1.1 jruoho the namespace node descriptor was reduced by 2 bytes as a result (Alexey 4705 1.1 jruoho Starikovskiy). 4706 1.1 jruoho 4707 1.1 jruoho Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield 4708 1.1 jruoho flag definitions within the headers for the predefined ACPI tables. These 4709 1.1 jruoho have been replaced by UINT8_BIT in order to increase the code portability of 4710 1.1 jruoho the subsystem. If the use of UINT8 remains a problem, we may be forced to 4711 1.1 jruoho eliminate bitfields entirely because of a lack of portability. 4712 1.1 jruoho 4713 1.1 jruoho Enhanced the performance of the AcpiUtUpdateObjectReference procedure. This 4714 1.1 jruoho is a frequently used function and this improvement increases the performance 4715 1.1 jruoho of the entire subsystem (Alexey Starikovskiy). 4716 1.1 jruoho 4717 1.1 jruoho Fixed several possible memory leaks and the inverse - premature object 4718 1.1 jruoho deletion (Alexey Starikovskiy). 4719 1.1 jruoho 4720 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4721 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4722 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4723 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4724 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4725 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4726 1.1 jruoho the compiler options used during generation. 4727 1.1 jruoho 4728 1.1 jruoho Previous Release: 4729 1.1 jruoho Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total 4730 1.1 jruoho Debug Version: 165.2K Code, 69.6K Data, 234.8K Total 4731 1.1 jruoho Current Release: 4732 1.1 jruoho Non-Debug Version: 78.6K Code, 11.6K Data, 90.2K Total 4733 1.1 jruoho Debug Version: 170.0K Code, 69.7K Data, 239.7K Total 4734 1.1 jruoho 4735 1.1 jruoho ---------------------------------------- 4736 1.1 jruoho 24 June 2005. Summary of changes for version 20050624: 4737 1.1 jruoho 4738 1.1 jruoho 1) ACPI CA Core Subsystem: 4739 1.1 jruoho 4740 1.1 jruoho Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for 4741 1.1 jruoho the host-defined cache object. This allows the OSL implementation to define 4742 1.1 jruoho and type this object in any manner desired, simplifying the OSL 4743 1.1 jruoho implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for 4744 1.1 jruoho Linux, and should be defined in the OS-specific header file for other 4745 1.1 jruoho operating systems as required. 4746 1.1 jruoho 4747 1.1 jruoho Changed the interface to AcpiOsAcquireObject to directly return the 4748 1.1 jruoho requested object as the function return (instead of ACPI_STATUS.) This 4749 1.1 jruoho change was made for performance reasons, since this is the purpose of the 4750 1.1 jruoho interface in the first place. AcpiOsAcquireObject is now similar to the 4751 1.1 jruoho AcpiOsAllocate interface. 4752 1.1 jruoho 4753 1.1 jruoho Implemented a new AML debugger command named Businfo. This command displays 4754 1.1 jruoho information about all devices that have an associate _PRT object. The _ADR, 4755 1.1 jruoho _HID, _UID, and _CID are displayed for these devices. 4756 1.1 jruoho 4757 1.1 jruoho Modified the initialization sequence in AcpiInitializeSubsystem to call the 4758 1.1 jruoho OSL interface AcpiOslInitialize first, before any local initialization. This 4759 1.1 jruoho change was required because the global initialization now calls OSL 4760 1.1 jruoho interfaces. 4761 1.1 jruoho 4762 1.1 jruoho Enhanced the Dump command to display the entire contents of Package objects 4763 1.1 jruoho (including all sub-objects and their values.) 4764 1.1 jruoho 4765 1.1 jruoho Restructured the code base to split some files because of size and/or 4766 1.1 jruoho because the code logically belonged in a separate file. New files are listed 4767 1.1 jruoho below. All makefiles and project files included in the ACPI CA release have 4768 1.1 jruoho been updated. 4769 1.1 jruoho utilities/utcache.c /* Local cache interfaces */ 4770 1.1 jruoho utilities/utmutex.c /* Local mutex support */ 4771 1.1 jruoho utilities/utstate.c /* State object support */ 4772 1.1 jruoho interpreter/parser/psloop.c /* Main AML parse loop */ 4773 1.1 jruoho 4774 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4775 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4776 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4777 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4778 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4779 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4780 1.1 jruoho the compiler options used during generation. 4781 1.1 jruoho 4782 1.1 jruoho Previous Release: 4783 1.1 jruoho Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 4784 1.1 jruoho Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 4785 1.1 jruoho Current Release: 4786 1.1 jruoho Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total 4787 1.1 jruoho Debug Version: 165.2K Code, 69.6K Data, 234.8K Total 4788 1.1 jruoho 4789 1.1 jruoho 4790 1.1 jruoho 2) iASL Compiler/Disassembler: 4791 1.1 jruoho 4792 1.1 jruoho Fixed a regression introduced in version 20050513 where the use of a Package 4793 1.1 jruoho object within a Case() statement caused a compile time exception. The 4794 1.1 jruoho original behavior has been restored (a Match() operator is emitted.) 4795 1.1 jruoho 4796 1.1 jruoho ---------------------------------------- 4797 1.1 jruoho 17 June 2005. Summary of changes for version 20050617: 4798 1.1 jruoho 4799 1.1 jruoho 1) ACPI CA Core Subsystem: 4800 1.1 jruoho 4801 1.1 jruoho Moved the object cache operations into the OS interface layer (OSL) to allow 4802 1.1 jruoho the host OS to handle these operations if desired (for example, the Linux 4803 1.1 jruoho OSL will invoke the slab allocator). This support is optional; the compile 4804 1.1 jruoho time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache 4805 1.1 jruoho code in the ACPI CA core. The new OSL interfaces are shown below. See 4806 1.1 jruoho utalloc.c for an example implementation, and acpiosxf.h for the exact 4807 1.1 jruoho interface definitions. With assistance from Alexey Starikovskiy. 4808 1.1 jruoho AcpiOsCreateCache 4809 1.1 jruoho AcpiOsDeleteCache 4810 1.1 jruoho AcpiOsPurgeCache 4811 1.1 jruoho AcpiOsAcquireObject 4812 1.1 jruoho AcpiOsReleaseObject 4813 1.1 jruoho 4814 1.1 jruoho Modified the interfaces to AcpiOsAcquireLock and AcpiOsReleaseLock to return 4815 1.1 jruoho and restore a flags parameter. This fits better with many OS lock models. 4816 1.1 jruoho Note: the current execution state (interrupt handler or not) is no longer 4817 1.1 jruoho passed to these interfaces. If necessary, the OSL must determine this state 4818 1.1 jruoho by itself, a simple and fast operation. With assistance from Alexey 4819 1.1 jruoho Starikovskiy. 4820 1.1 jruoho 4821 1.1 jruoho Fixed a problem in the ACPI table handling where a valid XSDT was assumed 4822 1.1 jruoho present if the revision of the RSDP was 2 or greater. According to the ACPI 4823 1.1 jruoho specification, the XSDT is optional in all cases, and the table manager 4824 1.1 jruoho therefore now checks for both an RSDP >=2 and a valid XSDT pointer. 4825 1.1 jruoho Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain 4826 1.1 jruoho only the RSDT. 4827 1.1 jruoho 4828 1.1 jruoho Fixed an interpreter problem with the Mid() operator in the case of an input 4829 1.1 jruoho string where the resulting output string is of zero length. It now correctly 4830 1.1 jruoho returns a valid, null terminated string object instead of a string object 4831 1.1 jruoho with a null pointer. 4832 1.1 jruoho 4833 1.1 jruoho Fixed a problem with the control method argument handling to allow a store 4834 1.1 jruoho to an Arg object that already contains an object of type Device. The Device 4835 1.1 jruoho object is now correctly overwritten. Previously, an error was returned. 4836 1.1 jruoho 4837 1.1 jruoho 4838 1.1 jruoho Enhanced the debugger Find command to emit object values in addition to the 4839 1.1 jruoho found object pathnames. The output format is the same as the dump namespace 4840 1.1 jruoho command. 4841 1.1 jruoho 4842 1.1 jruoho Enhanced the debugger Set command. It now has the ability to set the value 4843 1.1 jruoho of any Named integer object in the namespace (Previously, only method locals 4844 1.1 jruoho and args could be set.) 4845 1.1 jruoho 4846 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4847 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4848 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4849 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4850 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4851 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4852 1.1 jruoho the compiler options used during generation. 4853 1.1 jruoho 4854 1.1 jruoho Previous Release: 4855 1.1 jruoho Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 4856 1.1 jruoho Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 4857 1.1 jruoho Current Release: 4858 1.1 jruoho Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 4859 1.1 jruoho Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 4860 1.1 jruoho 4861 1.1 jruoho 4862 1.1 jruoho 2) iASL Compiler/Disassembler: 4863 1.1 jruoho 4864 1.1 jruoho Fixed a regression in the disassembler where if/else/while constructs were 4865 1.1 jruoho output incorrectly. This problem was introduced in the previous release 4866 1.1 jruoho (20050526). This problem also affected the single-step disassembly in the 4867 1.1 jruoho debugger. 4868 1.1 jruoho 4869 1.1 jruoho Fixed a problem where compiling the reserved _OSI method would randomly (but 4870 1.1 jruoho rarely) produce compile errors. 4871 1.1 jruoho 4872 1.1 jruoho Enhanced the disassembler to emit compilable code in the face of incorrect 4873 1.1 jruoho AML resource descriptors. If the optional ResourceSourceIndex is present, 4874 1.1 jruoho but the ResourceSource is not, do not emit the ResourceSourceIndex in the 4875 1.1 jruoho disassembly. Otherwise, the resulting code cannot be compiled without 4876 1.1 jruoho errors. 4877 1.1 jruoho 4878 1.1 jruoho ---------------------------------------- 4879 1.1 jruoho 26 May 2005. Summary of changes for version 20050526: 4880 1.1 jruoho 4881 1.1 jruoho 1) ACPI CA Core Subsystem: 4882 1.1 jruoho 4883 1.1 jruoho Implemented support to execute Type 1 and Type 2 AML opcodes appearing at 4884 1.1 jruoho the module level (not within a control method.) These opcodes are executed 4885 1.1 jruoho exactly once at the time the table is loaded. This type of code was legal up 4886 1.1 jruoho until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in 4887 1.1 jruoho order to provide backwards compatibility with earlier BIOS implementations. 4888 1.1 jruoho This eliminates the "Encountered executable code at module level" warning 4889 1.1 jruoho that was previously generated upon detection of such code. 4890 1.1 jruoho 4891 1.1 jruoho Fixed a problem in the interpreter where an AE_NOT_FOUND exception could 4892 1.1 jruoho inadvertently be generated during the lookup of namespace objects in the 4893 1.1 jruoho second pass parse of ACPI tables and control methods. It appears that this 4894 1.1 jruoho problem could occur during the resolution of forward references to namespace 4895 1.1 jruoho objects. 4896 1.1 jruoho 4897 1.1 jruoho Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function, 4898 1.1 jruoho corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This 4899 1.1 jruoho allows the deadlock detection debug code to be compiled out in the normal 4900 1.1 jruoho case, improving mutex performance (and overall subsystem performance) 4901 1.1 jruoho considerably. 4902 1.1 jruoho 4903 1.1 jruoho Implemented a handful of miscellaneous fixes for possible memory leaks on 4904 1.1 jruoho error conditions and error handling control paths. These fixes were 4905 1.1 jruoho suggested by FreeBSD and the Coverity Prevent source code analysis tool. 4906 1.1 jruoho 4907 1.1 jruoho Added a check for a null RSDT pointer in AcpiGetFirmwareTable (tbxfroot.c) 4908 1.1 jruoho to prevent a fault in this error case. 4909 1.1 jruoho 4910 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4911 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4912 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4913 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4914 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4915 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4916 1.1 jruoho the compiler options used during generation. 4917 1.1 jruoho 4918 1.1 jruoho Previous Release: 4919 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 4920 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 4921 1.1 jruoho Current Release: 4922 1.1 jruoho Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 4923 1.1 jruoho Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 4924 1.1 jruoho 4925 1.1 jruoho 4926 1.1 jruoho 2) iASL Compiler/Disassembler: 4927 1.1 jruoho 4928 1.1 jruoho Implemented support to allow Type 1 and Type 2 ASL operators to appear at 4929 1.1 jruoho the module level (not within a control method.) These operators will be 4930 1.1 jruoho executed once at the time the table is loaded. This type of code was legal 4931 1.1 jruoho up until the release of ACPI 2.0B (2002) and is now supported by the iASL 4932 1.1 jruoho compiler in order to provide backwards compatibility with earlier BIOS ASL 4933 1.1 jruoho code. 4934 1.1 jruoho 4935 1.1 jruoho The ACPI integer width (specified via the table revision ID or the -r 4936 1.1 jruoho override, 32 or 64 bits) is now used internally during compile-time constant 4937 1.1 jruoho folding to ensure that constants are truncated to 32 bits if necessary. 4938 1.1 jruoho Previously, the revision ID value was only emitted in the AML table header. 4939 1.1 jruoho 4940 1.1 jruoho An error message is now generated for the Mutex and Method operators if the 4941 1.1 jruoho SyncLevel parameter is outside the legal range of 0 through 15. 4942 1.1 jruoho 4943 1.1 jruoho Fixed a problem with the Method operator ParameterTypes list handling (ACPI 4944 1.1 jruoho 3.0). Previously, more than 2 types or 2 arguments generated a syntax error. 4945 1.1 jruoho The actual underlying implementation of method argument typechecking is 4946 1.1 jruoho still under development, however. 4947 1.1 jruoho 4948 1.1 jruoho ---------------------------------------- 4949 1.1 jruoho 13 May 2005. Summary of changes for version 20050513: 4950 1.1 jruoho 4951 1.1 jruoho 1) ACPI CA Core Subsystem: 4952 1.1 jruoho 4953 1.1 jruoho Implemented support for PCI Express root bridges -- added support for device 4954 1.1 jruoho PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup. 4955 1.1 jruoho 4956 1.1 jruoho The interpreter now automatically truncates incoming 64-bit constants to 32 4957 1.1 jruoho bits if currently executing out of a 32-bit ACPI table (Revision < 2). This 4958 1.1 jruoho also affects the iASL compiler constant folding. (Note: as per below, the 4959 1.1 jruoho iASL compiler no longer allows 64-bit constants within 32-bit tables.) 4960 1.1 jruoho 4961 1.1 jruoho Fixed a problem where string and buffer objects with "static" pointers 4962 1.1 jruoho (pointers to initialization data within an ACPI table) were not handled 4963 1.1 jruoho consistently. The internal object copy operation now always copies the data 4964 1.1 jruoho to a newly allocated buffer, regardless of whether the source object is 4965 1.1 jruoho static or not. 4966 1.1 jruoho 4967 1.1 jruoho Fixed a problem with the FromBCD operator where an implicit result 4968 1.1 jruoho conversion was improperly performed while storing the result to the target 4969 1.1 jruoho operand. Since this is an "explicit conversion" operator, the implicit 4970 1.1 jruoho conversion should never be performed on the output. 4971 1.1 jruoho 4972 1.1 jruoho Fixed a problem with the CopyObject operator where a copy to an existing 4973 1.1 jruoho named object did not always completely overwrite the existing object stored 4974 1.1 jruoho at name. Specifically, a buffer-to-buffer copy did not delete the existing 4975 1.1 jruoho buffer. 4976 1.1 jruoho 4977 1.1 jruoho Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces and 4978 1.1 jruoho structs for consistency. 4979 1.1 jruoho 4980 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 4981 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 4982 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4983 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 4984 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 4985 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 4986 1.1 jruoho the compiler options used during generation. 4987 1.1 jruoho 4988 1.1 jruoho Previous Release: 4989 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 4990 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 4991 1.1 jruoho Current Release: (Same sizes) 4992 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 4993 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 4994 1.1 jruoho 4995 1.1 jruoho 4996 1.1 jruoho 2) iASL Compiler/Disassembler: 4997 1.1 jruoho 4998 1.1 jruoho The compiler now emits a warning if an attempt is made to generate a 64-bit 4999 1.1 jruoho integer constant from within a 32-bit ACPI table (Revision < 2). The integer 5000 1.1 jruoho is truncated to 32 bits. 5001 1.1 jruoho 5002 1.1 jruoho Fixed a problem with large package objects: if the static length of the 5003 1.1 jruoho package is greater than 255, the "variable length package" opcode is 5004 1.1 jruoho emitted. Previously, this caused an error. This requires an update to the 5005 1.1 jruoho ACPI spec, since it currently (incorrectly) states that packages larger than 5006 1.1 jruoho 255 elements are not allowed. 5007 1.1 jruoho 5008 1.1 jruoho The disassembler now correctly handles variable length packages and packages 5009 1.1 jruoho larger than 255 elements. 5010 1.1 jruoho 5011 1.1 jruoho ---------------------------------------- 5012 1.1 jruoho 08 April 2005. Summary of changes for version 20050408: 5013 1.1 jruoho 5014 1.1 jruoho 1) ACPI CA Core Subsystem: 5015 1.1 jruoho 5016 1.1 jruoho Fixed three cases in the interpreter where an "index" argument to an ASL 5017 1.1 jruoho function was still (internally) 32 bits instead of the required 64 bits. 5018 1.1 jruoho This was the Index argument to the Index, Mid, and Match operators. 5019 1.1 jruoho 5020 1.1 jruoho The "strupr" function is now permanently local (AcpiUtStrupr), since this is 5021 1.1 jruoho not a POSIX-defined function and not present in most kernel-level C 5022 1.1 jruoho libraries. All references to the C library strupr function have been removed 5023 1.1 jruoho from the headers. 5024 1.1 jruoho 5025 1.1 jruoho Completed the deployment of static functions/prototypes. All prototypes with 5026 1.1 jruoho the static attribute have been moved from the headers to the owning C file. 5027 1.1 jruoho 5028 1.1 jruoho Implemented an extract option (-e) for the AcpiBin utility (AML binary 5029 1.1 jruoho utility). This option allows the utility to extract individual ACPI tables 5030 1.1 jruoho from the output of AcpiDmp. It provides the same functionality of the 5031 1.1 jruoho acpixtract.pl perl script without the worry of setting the correct perl 5032 1.1 jruoho options. AcpiBin runs on Windows and has not yet been generated/validated in 5033 1.1 jruoho the Linux/Unix environment (but should be soon). 5034 1.1 jruoho 5035 1.1 jruoho Updated and fixed the table dump option for AcpiBin (-d). This option 5036 1.1 jruoho converts a single ACPI table to a hex/ascii file, similar to the output of 5037 1.1 jruoho AcpiDmp. 5038 1.1 jruoho 5039 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5040 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5041 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5042 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5043 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5044 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5045 1.1 jruoho the compiler options used during generation. 5046 1.1 jruoho 5047 1.1 jruoho Previous Release: 5048 1.1 jruoho Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total 5049 1.1 jruoho Debug Version: 163.5K Code, 69.3K Data, 232.8K Total 5050 1.1 jruoho Current Release: 5051 1.1 jruoho Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 5052 1.1 jruoho Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 5053 1.1 jruoho 5054 1.1 jruoho 5055 1.1 jruoho 2) iASL Compiler/Disassembler: 5056 1.1 jruoho 5057 1.1 jruoho Disassembler fix: Added a check to ensure that the table length found in the 5058 1.1 jruoho ACPI table header within the input file is not longer than the actual input 5059 1.1 jruoho file size. This indicates some kind of file or table corruption. 5060 1.1 jruoho 5061 1.1 jruoho ---------------------------------------- 5062 1.1 jruoho 29 March 2005. Summary of changes for version 20050329: 5063 1.1 jruoho 5064 1.1 jruoho 1) ACPI CA Core Subsystem: 5065 1.1 jruoho 5066 1.1 jruoho An error is now generated if an attempt is made to create a Buffer Field of 5067 1.1 jruoho length zero (A CreateField with a length operand of zero.) 5068 1.1 jruoho 5069 1.1 jruoho The interpreter now issues a warning whenever executable code at the module 5070 1.1 jruoho level is detected during ACPI table load. This will give some idea of the 5071 1.1 jruoho prevalence of this type of code. 5072 1.1 jruoho 5073 1.1 jruoho Implemented support for references to named objects (other than control 5074 1.1 jruoho methods) within package objects. 5075 1.1 jruoho 5076 1.1 jruoho Enhanced package object output for the debug object. Package objects are now 5077 1.1 jruoho completely dumped, showing all elements. 5078 1.1 jruoho 5079 1.1 jruoho Enhanced miscellaneous object output for the debug object. Any object can 5080 1.1 jruoho now be written to the debug object (for example, a device object can be 5081 1.1 jruoho written, and the type of the object will be displayed.) 5082 1.1 jruoho 5083 1.1 jruoho The "static" qualifier has been added to all local functions across both the 5084 1.1 jruoho core subsystem and the iASL compiler. 5085 1.1 jruoho 5086 1.1 jruoho The number of "long" lines (> 80 chars) within the source has been 5087 1.1 jruoho significantly reduced, by about 1/3. 5088 1.1 jruoho 5089 1.1 jruoho Cleaned up all header files to ensure that all CA/iASL functions are 5090 1.1 jruoho prototyped (even static functions) and the formatting is consistent. 5091 1.1 jruoho 5092 1.1 jruoho Two new header files have been added, acopcode.h and acnames.h. 5093 1.1 jruoho 5094 1.1 jruoho Removed several obsolete functions that were no longer used. 5095 1.1 jruoho 5096 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5097 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5098 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5099 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5100 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5101 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5102 1.1 jruoho the compiler options used during generation. 5103 1.1 jruoho 5104 1.1 jruoho Previous Release: 5105 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5106 1.1 jruoho Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 5107 1.1 jruoho Current Release: 5108 1.1 jruoho Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total 5109 1.1 jruoho Debug Version: 163.5K Code, 69.3K Data, 232.8K Total 5110 1.1 jruoho 5111 1.1 jruoho 5112 1.1 jruoho 5113 1.1 jruoho 2) iASL Compiler/Disassembler: 5114 1.1 jruoho 5115 1.1 jruoho Fixed a problem with the resource descriptor generation/support. For the 5116 1.1 jruoho ResourceSourceIndex and the ResourceSource fields, both must be present, or 5117 1.1 jruoho both must be not present - can't have one without the other. 5118 1.1 jruoho 5119 1.1 jruoho The compiler now returns non-zero from the main procedure if any errors have 5120 1.1 jruoho occurred during the compilation. 5121 1.1 jruoho 5122 1.1 jruoho 5123 1.1 jruoho ---------------------------------------- 5124 1.1 jruoho 09 March 2005. Summary of changes for version 20050309: 5125 1.1 jruoho 5126 1.1 jruoho 1) ACPI CA Core Subsystem: 5127 1.1 jruoho 5128 1.1 jruoho The string-to-buffer implicit conversion code has been modified again after 5129 1.1 jruoho a change to the ACPI specification. In order to match the behavior of the 5130 1.1 jruoho other major ACPI implementation, the target buffer is no longer truncated if 5131 1.1 jruoho the source string is smaller than an existing target buffer. This change 5132 1.1 jruoho requires an update to the ACPI spec, and should eliminate the recent 5133 1.1 jruoho AE_AML_BUFFER_LIMIT issues. 5134 1.1 jruoho 5135 1.1 jruoho The "implicit return" support was rewritten to a new algorithm that solves 5136 1.1 jruoho the general case. Rather than attempt to determine when a method is about to 5137 1.1 jruoho exit, the result of every ASL operator is saved momentarily until the very 5138 1.1 jruoho next ASL operator is executed. Therefore, no matter how the method exits, 5139 1.1 jruoho there will always be a saved implicit return value. This feature is only 5140 1.1 jruoho enabled with the AcpiGbl_EnableInterpreterSlack flag, and should eliminate 5141 1.1 jruoho AE_AML_NO_RETURN_VALUE errors when enabled. 5142 1.1 jruoho 5143 1.1 jruoho Implemented implicit conversion support for the predicate (operand) of the 5144 1.1 jruoho If, Else, and While operators. String and Buffer arguments are automatically 5145 1.1 jruoho converted to Integers. 5146 1.1 jruoho 5147 1.1 jruoho Changed the string-to-integer conversion behavior to match the new ACPI 5148 1.1 jruoho errata: "If no integer object exists, a new integer is created. The ASCII 5149 1.1 jruoho string is interpreted as a hexadecimal constant. Each string character is 5150 1.1 jruoho interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting 5151 1.1 jruoho with the first character as the most significant digit, and ending with the 5152 1.1 jruoho first non-hexadecimal character or end-of-string." This means that the first 5153 1.1 jruoho non-hex character terminates the conversion and this is the code that was 5154 1.1 jruoho changed. 5155 1.1 jruoho 5156 1.1 jruoho Fixed a problem where the ObjectType operator would fail (fault) when used 5157 1.1 jruoho on an Index of a Package which pointed to a null package element. The 5158 1.1 jruoho operator now properly returns zero (Uninitialized) in this case. 5159 1.1 jruoho 5160 1.1 jruoho Fixed a problem where the While operator used excessive memory by not 5161 1.1 jruoho properly popping the result stack during execution. There was no memory leak 5162 1.1 jruoho after execution, however. (Code provided by Valery Podrezov.) 5163 1.1 jruoho 5164 1.1 jruoho Fixed a problem where references to control methods within Package objects 5165 1.1 jruoho caused the method to be invoked, instead of producing a reference object 5166 1.1 jruoho pointing to the method. 5167 1.1 jruoho 5168 1.1 jruoho Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) to 5169 1.1 jruoho improve performance and reduce code size. (Code provided by Alexey 5170 1.1 jruoho Starikovskiy.) 5171 1.1 jruoho 5172 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5173 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5174 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5175 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5176 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5177 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5178 1.1 jruoho the compiler options used during generation. 5179 1.1 jruoho 5180 1.1 jruoho Previous Release: 5181 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5182 1.1 jruoho Debug Version: 165.4K Code, 69.6K Data, 236.0K Total 5183 1.1 jruoho Current Release: 5184 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5185 1.1 jruoho Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 5186 1.1 jruoho 5187 1.1 jruoho 5188 1.1 jruoho 2) iASL Compiler/Disassembler: 5189 1.1 jruoho 5190 1.1 jruoho Fixed a problem with the Return operator with no arguments. Since the AML 5191 1.1 jruoho grammar for the byte encoding requires an operand for the Return opcode, the 5192 1.1 jruoho compiler now emits a Return(Zero) for this case. An ACPI specification 5193 1.1 jruoho update has been written for this case. 5194 1.1 jruoho 5195 1.1 jruoho For tables other than the DSDT, namepath optimization is automatically 5196 1.1 jruoho disabled. This is because SSDTs can be loaded anywhere in the namespace, the 5197 1.1 jruoho compiler has no knowledge of where, and thus cannot optimize namepaths. 5198 1.1 jruoho 5199 1.1 jruoho Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was 5200 1.1 jruoho inadvertently omitted from the ACPI specification, and will require an 5201 1.1 jruoho update to the spec. 5202 1.1 jruoho 5203 1.1 jruoho The source file scan for ASCII characters is now optional (-a). This change 5204 1.1 jruoho was made because some vendors place non-ascii characters within comments. 5205 1.1 jruoho However, the scan is simply a brute-force byte compare to ensure all 5206 1.1 jruoho characters in the file are in the range 0x00 to 0x7F. 5207 1.1 jruoho 5208 1.1 jruoho Fixed a problem with the CondRefOf operator where the compiler was 5209 1.1 jruoho inappropriately checking for the existence of the target. Since the point of 5210 1.1 jruoho the operator is to check for the existence of the target at run-time, the 5211 1.1 jruoho compiler no longer checks for the target existence. 5212 1.1 jruoho 5213 1.1 jruoho Fixed a problem where errors generated from the internal AML interpreter 5214 1.1 jruoho during constant folding were not handled properly, causing a fault. 5215 1.1 jruoho 5216 1.1 jruoho Fixed a problem with overly aggressive range checking for the Stall 5217 1.1 jruoho operator. The valid range (max 255) is now only checked if the operand is of 5218 1.1 jruoho type Integer. All other operand types cannot be statically checked. 5219 1.1 jruoho 5220 1.1 jruoho Fixed a problem where control method references within the RefOf, DeRefOf, 5221 1.1 jruoho and ObjectType operators were not treated properly. They are now treated as 5222 1.1 jruoho actual references, not method invocations. 5223 1.1 jruoho 5224 1.1 jruoho Fixed and enhanced the "list namespace" option (-ln). This option was broken 5225 1.1 jruoho a number of releases ago. 5226 1.1 jruoho 5227 1.1 jruoho Improved error handling for the Field, IndexField, and BankField operators. 5228 1.1 jruoho The compiler now cleanly reports and recovers from errors in the field 5229 1.1 jruoho component (FieldUnit) list. 5230 1.1 jruoho 5231 1.1 jruoho Fixed a disassembler problem where the optional ResourceDescriptor fields 5232 1.1 jruoho TRS and TTP were not always handled correctly. 5233 1.1 jruoho 5234 1.1 jruoho Disassembler - Comments in output now use "//" instead of "/*" 5235 1.1 jruoho 5236 1.1 jruoho ---------------------------------------- 5237 1.1 jruoho 28 February 2005. Summary of changes for version 20050228: 5238 1.1 jruoho 5239 1.1 jruoho 1) ACPI CA Core Subsystem: 5240 1.1 jruoho 5241 1.1 jruoho Fixed a problem where the result of an Index() operator (an object 5242 1.1 jruoho reference) must increment the reference count on the target object for the 5243 1.1 jruoho life of the object reference. 5244 1.1 jruoho 5245 1.1 jruoho Implemented AML Interpreter and Debugger support for the new ACPI 3.0 5246 1.1 jruoho Extended Address (IO, Memory, Space), QwordSpace, DwordSpace, and WordSpace 5247 1.1 jruoho resource descriptors. 5248 1.1 jruoho 5249 1.1 jruoho Implemented support in the _OSI method for the ACPI 3.0 "Extended Address 5250 1.1 jruoho Space Descriptor" string, indicating interpreter support for the descriptors 5251 1.1 jruoho above. 5252 1.1 jruoho 5253 1.1 jruoho Implemented header support for the new ACPI 3.0 FADT flag bits. 5254 1.1 jruoho 5255 1.1 jruoho Implemented header support for the new ACPI 3.0 PCI Express bits for the PM1 5256 1.1 jruoho status/enable registers. 5257 1.1 jruoho 5258 1.1 jruoho Updated header support for the MADT processor local Apic struct and MADT 5259 1.1 jruoho platform interrupt source struct for new ACPI 3.0 fields. 5260 1.1 jruoho 5261 1.1 jruoho Implemented header support for the SRAT and SLIT ACPI tables. 5262 1.1 jruoho 5263 1.1 jruoho Implemented the -s switch in AcpiExec to enable the "InterpreterSlack" flag 5264 1.1 jruoho at runtime. 5265 1.1 jruoho 5266 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5267 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5268 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5269 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5270 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5271 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5272 1.1 jruoho the compiler options used during generation. 5273 1.1 jruoho 5274 1.1 jruoho Previous Release: 5275 1.1 jruoho Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total 5276 1.1 jruoho Debug Version: 164.9K Code, 69.2K Data, 234.1K Total 5277 1.1 jruoho Current Release: 5278 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5279 1.1 jruoho Debug Version: 165.4K Code, 69.6K Data, 236.0K Total 5280 1.1 jruoho 5281 1.1 jruoho 5282 1.1 jruoho 2) iASL Compiler/Disassembler: 5283 1.1 jruoho 5284 1.1 jruoho Fixed a problem with the internal 64-bit String-to-integer conversion with 5285 1.1 jruoho strings less than two characters long. 5286 1.1 jruoho 5287 1.1 jruoho Fixed a problem with constant folding where the result of the Index() 5288 1.1 jruoho operator can not be considered a constant. This means that Index() cannot be 5289 1.1 jruoho a type3 opcode and this will require an update to the ACPI specification. 5290 1.1 jruoho 5291 1.1 jruoho Disassembler: Implemented support for the TTP, MTP, and TRS resource 5292 1.1 jruoho descriptor fields. These fields were inadvertently ignored and not output in 5293 1.1 jruoho the disassembly of the resource descriptor. 5294 1.1 jruoho 5295 1.1 jruoho 5296 1.1 jruoho ---------------------------------------- 5297 1.1 jruoho 11 February 2005. Summary of changes for version 20050211: 5298 1.1 jruoho 5299 1.1 jruoho 1) ACPI CA Core Subsystem: 5300 1.1 jruoho 5301 1.1 jruoho Implemented ACPI 3.0 support for implicit conversion within the Match() 5302 1.1 jruoho operator. MatchObjects can now be of type integer, buffer, or string instead 5303 1.1 jruoho of just type integer. Package elements are implicitly converted to the type 5304 1.1 jruoho of the MatchObject. This change aligns the behavior of Match() with the 5305 1.1 jruoho behavior of the other logical operators (LLess(), etc.) It also requires an 5306 1.1 jruoho errata change to the ACPI specification as this support was intended for 5307 1.1 jruoho ACPI 3.0, but was inadvertently omitted. 5308 1.1 jruoho 5309 1.1 jruoho Fixed a problem with the internal implicit "to buffer" conversion. Strings 5310 1.1 jruoho that are converted to buffers will cause buffer truncation if the string is 5311 1.1 jruoho smaller than the target buffer. Integers that are converted to buffers will 5312 1.1 jruoho not cause buffer truncation, only zero extension (both as per the ACPI 5313 1.1 jruoho spec.) The problem was introduced when code was added to truncate the 5314 1.1 jruoho buffer, but this should not be performed in all cases, only the string case. 5315 1.1 jruoho 5316 1.1 jruoho Fixed a problem with the Buffer and Package operators where the interpreter 5317 1.1 jruoho would get confused if two such operators were used as operands to an ASL 5318 1.1 jruoho operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result 5319 1.1 jruoho stack was not being popped after the execution of these operators, resulting 5320 1.1 jruoho in an AE_NO_RETURN_VALUE exception. 5321 1.1 jruoho 5322 1.1 jruoho Fixed a problem with constructs of the form Store(Index(...),...). The 5323 1.1 jruoho reference object returned from Index was inadvertently resolved to an actual 5324 1.1 jruoho value. This problem was introduced in version 20050114 when the behavior of 5325 1.1 jruoho Store() was modified to restrict the object types that can be used as the 5326 1.1 jruoho source operand (to match the ACPI specification.) 5327 1.1 jruoho 5328 1.1 jruoho Reduced excessive stack use within the AcpiGetObjectInfo procedure. 5329 1.1 jruoho 5330 1.1 jruoho Added a fix to aclinux.h to allow generation of AcpiExec on Linux. 5331 1.1 jruoho 5332 1.1 jruoho Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct. 5333 1.1 jruoho 5334 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5335 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5336 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5337 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5338 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5339 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5340 1.1 jruoho the compiler options used during generation. 5341 1.1 jruoho 5342 1.1 jruoho Previous Release: 5343 1.1 jruoho Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 5344 1.1 jruoho Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 5345 1.1 jruoho Current Release: 5346 1.1 jruoho Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total 5347 1.1 jruoho Debug Version: 164.9K Code, 69.2K Data, 234.1K Total 5348 1.1 jruoho 5349 1.1 jruoho 5350 1.1 jruoho 2) iASL Compiler/Disassembler: 5351 1.1 jruoho 5352 1.1 jruoho Fixed a code generation problem in the constant folding optimization code 5353 1.1 jruoho where incorrect code was generated if a constant was reduced to a buffer 5354 1.1 jruoho object (i.e., a reduced type 5 opcode.) 5355 1.1 jruoho 5356 1.1 jruoho Fixed a typechecking problem for the ToBuffer operator. Caused by an 5357 1.1 jruoho incorrect return type in the internal opcode information table. 5358 1.1 jruoho 5359 1.1 jruoho ---------------------------------------- 5360 1.1 jruoho 25 January 2005. Summary of changes for version 20050125: 5361 1.1 jruoho 5362 1.1 jruoho 1) ACPI CA Core Subsystem: 5363 1.1 jruoho 5364 1.1 jruoho Fixed a recently introduced problem with the Global Lock where the 5365 1.1 jruoho underlying semaphore was not created. This problem was introduced in 5366 1.1 jruoho version 20050114, and caused an AE_AML_NO_OPERAND exception during an 5367 1.1 jruoho Acquire() operation on _GL. 5368 1.1 jruoho 5369 1.1 jruoho The local object cache is now optional, and is disabled by default. Both 5370 1.1 jruoho AcpiExec and the iASL compiler enable the cache because they run in user 5371 1.1 jruoho mode and this enhances their performance. #define ACPI_ENABLE_OBJECT_CACHE 5372 1.1 jruoho to enable the local cache. 5373 1.1 jruoho 5374 1.1 jruoho Fixed an issue in the internal function AcpiUtEvaluateObject concerning the 5375 1.1 jruoho optional "implicit return" support where an error was returned if no return 5376 1.1 jruoho object was expected, but one was implicitly returned. AE_OK is now returned 5377 1.1 jruoho in this case and the implicitly returned object is deleted. 5378 1.1 jruoho AcpiUtEvaluateObject is only occasionally used, and only to execute reserved 5379 1.1 jruoho methods such as _STA and _INI where the return type is known up front. 5380 1.1 jruoho 5381 1.1 jruoho Fixed a few issues with the internal convert-to-integer code. It now returns 5382 1.1 jruoho an error if an attempt is made to convert a null string, a string of only 5383 1.1 jruoho blanks/tabs, or a zero-length buffer. This affects both implicit conversion 5384 1.1 jruoho and explicit conversion via the ToInteger() operator. 5385 1.1 jruoho 5386 1.1 jruoho The internal debug code in AcpiUtAcquireMutex has been commented out. It is 5387 1.1 jruoho not needed for normal operation and should increase the performance of the 5388 1.1 jruoho entire subsystem. The code remains in case it is needed for debug purposes 5389 1.1 jruoho again. 5390 1.1 jruoho 5391 1.1 jruoho The AcpiExec source and makefile are included in the Unix/Linux package for 5392 1.1 jruoho the first time. 5393 1.1 jruoho 5394 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5395 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5396 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5397 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5398 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5399 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5400 1.1 jruoho the compiler options used during generation. 5401 1.1 jruoho 5402 1.1 jruoho Previous Release: 5403 1.1 jruoho Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total 5404 1.1 jruoho Debug Version: 165.4K Code, 69.4K Data, 234.8K Total 5405 1.1 jruoho Current Release: 5406 1.1 jruoho Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 5407 1.1 jruoho Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 5408 1.1 jruoho 5409 1.1 jruoho 2) iASL Compiler/Disassembler: 5410 1.1 jruoho 5411 1.1 jruoho Switch/Case support: A warning is now issued if the type of the Switch value 5412 1.1 jruoho cannot be determined at compile time. For example, Switch(Arg0) will 5413 1.1 jruoho generate the warning, and the type is assumed to be an integer. As per the 5414 1.1 jruoho ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate the 5415 1.1 jruoho warning. 5416 1.1 jruoho 5417 1.1 jruoho Switch/Case support: Implemented support for buffer and string objects as 5418 1.1 jruoho the switch value. This is an ACPI 3.0 feature, now that LEqual supports 5419 1.1 jruoho buffers and strings. 5420 1.1 jruoho 5421 1.1 jruoho Switch/Case support: The emitted code for the LEqual() comparisons now uses 5422 1.1 jruoho the switch value as the first operand, not the second. The case value is now 5423 1.1 jruoho the second operand, and this allows the case value to be implicitly 5424 1.1 jruoho converted to the type of the switch value, not the other way around. 5425 1.1 jruoho 5426 1.1 jruoho Switch/Case support: Temporary variables are now emitted immediately within 5427 1.1 jruoho the control method, not at the global level. This means that there are now 5428 1.1 jruoho 36 temps available per-method, not 36 temps per-module as was the case with 5429 1.1 jruoho the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.) 5430 1.1 jruoho 5431 1.1 jruoho ---------------------------------------- 5432 1.1 jruoho 14 January 2005. Summary of changes for version 20050114: 5433 1.1 jruoho 5434 1.1 jruoho Added 2005 copyright to all module headers. This affects every module in 5435 1.1 jruoho the core subsystem, iASL compiler, and the utilities. 5436 1.1 jruoho 5437 1.1 jruoho 1) ACPI CA Core Subsystem: 5438 1.1 jruoho 5439 1.1 jruoho Fixed an issue with the String-to-Buffer conversion code where the string 5440 1.1 jruoho null terminator was not included in the buffer after conversion, but there 5441 1.1 jruoho is existing ASL that assumes the string null terminator is included. This is 5442 1.1 jruoho the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was 5443 1.1 jruoho introduced in the previous version when the code was updated to correctly 5444 1.1 jruoho set the converted buffer size as per the ACPI specification. The ACPI spec 5445 1.1 jruoho is ambiguous and will be updated to specify that the null terminator must be 5446 1.1 jruoho included in the converted buffer. This also affects the ToBuffer() ASL 5447 1.1 jruoho operator. 5448 1.1 jruoho 5449 1.1 jruoho Fixed a problem with the Mid() ASL/AML operator where it did not work 5450 1.1 jruoho correctly on Buffer objects. Newly created sub-buffers were not being marked 5451 1.1 jruoho as initialized. 5452 1.1 jruoho 5453 1.1 jruoho 5454 1.1 jruoho Fixed a problem in AcpiTbFindTable where incorrect string compares were 5455 1.1 jruoho performed on the OemId and OemTableId table header fields. These fields are 5456 1.1 jruoho not null terminated, so strncmp is now used instead of strcmp. 5457 1.1 jruoho 5458 1.1 jruoho Implemented a restriction on the Store() ASL/AML operator to align the 5459 1.1 jruoho behavior with the ACPI specification. Previously, any object could be used 5460 1.1 jruoho as the source operand. Now, the only objects that may be used are Integers, 5461 1.1 jruoho Buffers, Strings, Packages, Object References, and DDB Handles. If 5462 1.1 jruoho necessary, the original behavior can be restored by enabling the 5463 1.1 jruoho EnableInterpreterSlack flag. 5464 1.1 jruoho 5465 1.1 jruoho Enhanced the optional "implicit return" support to allow an implicit return 5466 1.1 jruoho value from methods that are invoked externally via the AcpiEvaluateObject 5467 1.1 jruoho interface. This enables implicit returns from the _STA and _INI methods, 5468 1.1 jruoho for example. 5469 1.1 jruoho 5470 1.1 jruoho Changed the Revision() ASL/AML operator to return the current version of the 5471 1.1 jruoho AML interpreter, in the YYYYMMDD format. Previously, it incorrectly returned 5472 1.1 jruoho the supported ACPI version (This is the function of the _REV method). 5473 1.1 jruoho 5474 1.1 jruoho Updated the _REV predefined method to return the currently supported version 5475 1.1 jruoho of ACPI, now 3. 5476 1.1 jruoho 5477 1.1 jruoho Implemented batch mode option for the AcpiExec utility (-b). 5478 1.1 jruoho 5479 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5480 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5481 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5482 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5483 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5484 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5485 1.1 jruoho the compiler options used during generation. 5486 1.1 jruoho 5487 1.1 jruoho Previous Release: 5488 1.1 jruoho Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5489 1.1 jruoho Debug Version: 165.3K Code, 69.4K Data, 234.7K Total 5490 1.1 jruoho Current Release: 5491 1.1 jruoho Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total 5492 1.1 jruoho Debug Version: 165.4K Code, 69.4K Data, 234.8K Total 5493 1.1 jruoho 5494 1.1 jruoho ---------------------------------------- 5495 1.1 jruoho 10 December 2004. Summary of changes for version 20041210: 5496 1.1 jruoho 5497 1.1 jruoho ACPI 3.0 support is nearing completion in both the iASL compiler and the 5498 1.1 jruoho ACPI CA core subsystem. 5499 1.1 jruoho 5500 1.1 jruoho 1) ACPI CA Core Subsystem: 5501 1.1 jruoho 5502 1.1 jruoho Fixed a problem in the ToDecimalString operator where the resulting string 5503 1.1 jruoho length was incorrectly calculated. The length is now calculated exactly, 5504 1.1 jruoho eliminating incorrect AE_STRING_LIMIT exceptions. 5505 1.1 jruoho 5506 1.1 jruoho Fixed a problem in the ToHexString operator to allow a maximum 200 character 5507 1.1 jruoho string to be produced. 5508 1.1 jruoho 5509 1.1 jruoho Fixed a problem in the internal string-to-buffer and buffer-to-buffer copy 5510 1.1 jruoho routine where the length of the resulting buffer was not truncated to the 5511 1.1 jruoho new size (if the target buffer already existed). 5512 1.1 jruoho 5513 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5514 1.1 jruoho shown below.

The optimizer shortened the AML code to a single byte opcode 5546 1.1 jruoho but did not update the surrounding package lengths. 5547 1.1 jruoho 5548 1.1 jruoho Changes to the Dma macro: All channels within the channel list must be in 5549 1.1 jruoho the range 0-7. Maximum 8 channels can be specified. BusMaster operand is 5550 1.1 jruoho optional (default is BusMaster). 5551 1.1 jruoho 5552 1.1 jruoho Implemented check for maximum 7 data bytes for the VendorShort macro. 5553 1.1 jruoho 5554 1.1 jruoho The ReadWrite parameter is now optional for the Memory32 and similar macros. 5555 1.1 jruoho 5556 1.1 jruoho ---------------------------------------- 5557 1.1 jruoho 03 December 2004. Summary of changes for version 20041203: 5558 1.1 jruoho 5559 1.1 jruoho 1) ACPI CA Core Subsystem: 5560 1.1 jruoho 5561 1.1 jruoho The low-level field insertion/extraction code (exfldio) has been completely 5562 1.1 jruoho rewritten to eliminate unnecessary complexity, bugs, and boundary 5563 1.1 jruoho conditions. 5564 1.1 jruoho 5565 1.1 jruoho Fixed a problem in the ToInteger, ToBuffer, ToHexString, and ToDecimalString 5566 1.1 jruoho operators where the input operand could be inadvertently deleted if no 5567 1.1 jruoho conversion was necessary (e.g., if the input to ToInteger was an Integer 5568 1.1 jruoho object.) 5569 1.1 jruoho 5570 1.1 jruoho Fixed a problem with the ToDecimalString and ToHexString where an incorrect 5571 1.1 jruoho exception code was returned if the resulting string would be > 200 chars. 5572 1.1 jruoho AE_STRING_LIMIT is now returned. 5573 1.1 jruoho 5574 1.1 jruoho Fixed a problem with the Concatenate operator where AE_OK was always 5575 1.1 jruoho returned, even if the operation failed. 5576 1.1 jruoho 5577 1.1 jruoho Fixed a problem in oswinxf (used by AcpiExec and iASL) to allow > 128 5578 1.1 jruoho semaphores to be allocated. 5579 1.1 jruoho 5580 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5581 1.1 jruoho shown below.

Problem was 5599 1.1 jruoho recently introduced in 20041119. 5600 1.1 jruoho 5601 1.1 jruoho Fixed a problem with the ToUUID macro where the upper nybble of each buffer 5602 1.1 jruoho byte was inadvertently set to zero. 5603 1.1 jruoho 5604 1.1 jruoho ---------------------------------------- 5605 1.1 jruoho 19 November 2004. Summary of changes for version 20041119: 5606 1.1 jruoho 5607 1.1 jruoho 1) ACPI CA Core Subsystem: 5608 1.1 jruoho 5609 1.1 jruoho Fixed a problem in the internal ConvertToInteger routine where new integers 5610 1.1 jruoho were not truncated to 32 bits for 32-bit ACPI tables. This routine converts 5611 1.1 jruoho buffers and strings to integers. 5612 1.1 jruoho 5613 1.1 jruoho Implemented support to store a value to an Index() on a String object. This 5614 1.1 jruoho is an ACPI 2.0 feature that had not yet been implemented. 5615 1.1 jruoho 5616 1.1 jruoho Implemented new behavior for storing objects to individual package elements 5617 1.1 jruoho (via the Index() operator). The previous behavior was to invoke the implicit 5618 1.1 jruoho conversion rules if an object was already present at the index. The new 5619 1.1 jruoho behavior is to simply delete any existing object and directly store the new 5620 1.1 jruoho object. Although the ACPI specification seems unclear on this subject, other 5621 1.1 jruoho ACPI implementations behave in this manner. (This is the root of the 5622 1.1 jruoho AE_BAD_HEX_CONSTANT issue.) 5623 1.1 jruoho 5624 1.1 jruoho Modified the RSDP memory scan mechanism to support the extended checksum for 5625 1.1 jruoho ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid 5626 1.1 jruoho RSDP signature is found with a valid checksum. 5627 1.1 jruoho 5628 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5629 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5630 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5631 1.1 jruoho any ACPI driver or OSPM code.

Summary of changes for version 20041105: 5650 1.1 jruoho 5651 1.1 jruoho 1) ACPI CA Core Subsystem: 5652 1.1 jruoho 5653 1.1 jruoho Implemented support for FADT revision 2. This was an interim table (between 5654 1.1 jruoho ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register. 5655 1.1 jruoho 5656 1.1 jruoho Implemented optional support to allow uninitialized LocalX and ArgX 5657 1.1 jruoho variables in a control method. The variables are initialized to an Integer 5658 1.1 jruoho object with a value of zero. This support is enabled by setting the 5659 1.1 jruoho AcpiGbl_EnableInterpreterSlack flag to TRUE. 5660 1.1 jruoho 5661 1.1 jruoho Implemented support for Integer objects for the SizeOf operator. Either 4 5662 1.1 jruoho or 8 is returned, depending on the current integer size (32-bit or 64-bit, 5663 1.1 jruoho depending on the parent table revision). 5664 1.1 jruoho 5665 1.1 jruoho Fixed a problem in the implementation of the SizeOf and ObjectType operators 5666 1.1 jruoho where the operand was resolved to a value too early, causing incorrect 5667 1.1 jruoho return values for some objects. 5668 1.1 jruoho 5669 1.1 jruoho Fixed some possible memory leaks during exceptional conditions. 5670 1.1 jruoho 5671 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5672 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5673 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5674 1.1 jruoho any ACPI driver or OSPM code.

Summary of changes for version 20041015: 5701 1.1 jruoho 5702 1.1 jruoho Note: ACPI CA is currently undergoing an in-depth and complete formal 5703 1.1 jruoho evaluation to test/verify the following areas. Other suggestions are 5704 1.1 jruoho welcome. This will result in an increase in the frequency of releases and 5705 1.1 jruoho the number of bug fixes in the next few months. 5706 1.1 jruoho - Functional tests for all ASL/AML operators 5707 1.1 jruoho - All implicit/explicit type conversions 5708 1.1 jruoho - Bit fields and operation regions 5709 1.1 jruoho - 64-bit math support and 32-bit-only "truncated" math support 5710 1.1 jruoho - Exceptional conditions, both compiler and interpreter 5711 1.1 jruoho - Dynamic object deletion and memory leaks 5712 1.1 jruoho - ACPI 3.0 support when implemented 5713 1.1 jruoho - External interfaces to the ACPI subsystem 5714 1.1 jruoho 5715 1.1 jruoho 5716 1.1 jruoho 1) ACPI CA Core Subsystem: 5717 1.1 jruoho 5718 1.1 jruoho Fixed two alignment issues on 64-bit platforms - within debug statements in 5719 1.1 jruoho AcpiEvGpeDetect and AcpiEvCreateGpeBlock. Removed references to the Address 5720 1.1 jruoho field within the non-aligned ACPI generic address structure. 5721 1.1 jruoho 5722 1.1 jruoho Fixed a problem in the Increment and Decrement operators where incorrect 5723 1.1 jruoho operand resolution could result in the inadvertent modification of the 5724 1.1 jruoho original integer when the integer is passed into another method as an 5725 1.1 jruoho argument and the arg is then incremented/decremented. 5726 1.1 jruoho 5727 1.1 jruoho Fixed a problem in the FromBCD operator where the upper 32-bits of a 64-bit 5728 1.1 jruoho BCD number were truncated during conversion. 5729 1.1 jruoho 5730 1.1 jruoho Fixed a problem in the ToDecimal operator where the length of the resulting 5731 1.1 jruoho string could be set incorrectly too long if the input operand was a Buffer 5732 1.1 jruoho object. 5733 1.1 jruoho 5734 1.1 jruoho Fixed a problem in the Logical operators (LLess, etc.) where a NULL byte (0) 5735 1.1 jruoho within a buffer would prematurely terminate a compare between buffer 5736 1.1 jruoho objects. 5737 1.1 jruoho 5738 1.1 jruoho Added a check for string overflow (>200 characters as per the ACPI 5739 1.1 jruoho specification) during the Concatenate operator with two string operands. 5740 1.1 jruoho 5741 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5742 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5743 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5744 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5745 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5746 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5747 1.1 jruoho the compiler options used during generation. 5748 1.1 jruoho 5749 1.1 jruoho Previous Release: 5750 1.1 jruoho Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total 5751 1.1 jruoho Debug Version: 164.6K Code, 68.5K Data, 233.1K Total 5752 1.1 jruoho Current Release: 5753 1.1 jruoho Non-Debug Version: 78.0K Code, 11.5K Data, 89.5K Total 5754 1.1 jruoho Debug Version: 164.8K Code, 68.6K Data, 233.4K Total 5755 1.1 jruoho 5756 1.1 jruoho 5757 1.1 jruoho 5758 1.1 jruoho 2) iASL Compiler/Disassembler: 5759 1.1 jruoho 5760 1.1 jruoho Allow the use of the ObjectType operator on uninitialized Locals and Args 5761 1.1 jruoho (returns 0 as per the ACPI specification). 5762 1.1 jruoho 5763 1.1 jruoho Fixed a problem where the compiler would fault if there was a syntax error 5764 1.1 jruoho in the FieldName of all of the various CreateXXXField operators. 5765 1.1 jruoho 5766 1.1 jruoho Disallow the use of lower case letters within the EISAID macro, as per the 5767 1.1 jruoho ACPI specification. All EISAID strings must be of the form "UUUNNNN" Where 5768 1.1 jruoho U is an uppercase letter and N is a hex digit. 5769 1.1 jruoho 5770 1.1 jruoho 5771 1.1 jruoho ---------------------------------------- 5772 1.1 jruoho 06 October 2004. Summary of changes for version 20041006: 5773 1.1 jruoho 5774 1.1 jruoho 1) ACPI CA Core Subsystem: 5775 1.1 jruoho 5776 1.1 jruoho Implemented support for the ACPI 3.0 Timer operator. This ASL function 5777 1.1 jruoho implements a 64-bit timer with 100 nanosecond granularity. 5778 1.1 jruoho 5779 1.1 jruoho Defined a new OSL interface, AcpiOsGetTimer. This interface is used to 5780 1.1 jruoho implement the ACPI 3.0 Timer operator. This allows the host OS to implement 5781 1.1 jruoho the timer with the best clock available. Also, it keeps the core subsystem 5782 1.1 jruoho out of the clock handling business, since the host OS (usually) performs 5783 1.1 jruoho this function. 5784 1.1 jruoho 5785 1.1 jruoho Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write) 5786 1.1 jruoho functions use a 64-bit address which is part of the packed ACPI Generic 5787 1.1 jruoho Address Structure. Since the structure is non-aligned, the alignment macros 5788 1.1 jruoho are now used to extract the address to a local variable before use. 5789 1.1 jruoho 5790 1.1 jruoho Fixed a problem where the ToInteger operator assumed all input strings were 5791 1.1 jruoho hexadecimal. The operator now handles both decimal strings and hex strings 5792 1.1 jruoho (prefixed with "0x"). 5793 1.1 jruoho 5794 1.1 jruoho Fixed a problem where the string length in the string object created as a 5795 1.1 jruoho result of the internal ConvertToString procedure could be incorrect. This 5796 1.1 jruoho potentially affected all implicit conversions and also the ToDecimalString 5797 1.1 jruoho and ToHexString operators. 5798 1.1 jruoho 5799 1.1 jruoho Fixed two problems in the ToString operator. If the length parameter was 5800 1.1 jruoho zero, an incorrect string object was created and the value of the input 5801 1.1 jruoho length parameter was inadvertently changed from zero to Ones. 5802 1.1 jruoho 5803 1.1 jruoho Fixed a problem where the optional ResourceSource string in the ExtendedIRQ 5804 1.1 jruoho resource macro was ignored. 5805 1.1 jruoho 5806 1.1 jruoho Simplified the interfaces to the internal division functions, reducing code 5807 1.1 jruoho size and complexity. 5808 1.1 jruoho 5809 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5810 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5811 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5812 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5813 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5814 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5815 1.1 jruoho the compiler options used during generation. 5816 1.1 jruoho 5817 1.1 jruoho Previous Release: 5818 1.1 jruoho Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total 5819 1.1 jruoho Debug Version: 164.5K Code, 68.3K Data, 232.8K Total 5820 1.1 jruoho Current Release: 5821 1.1 jruoho Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total 5822 1.1 jruoho Debug Version: 164.6K Code, 68.5K Data, 233.1K Total 5823 1.1 jruoho 5824 1.1 jruoho 5825 1.1 jruoho 2) iASL Compiler/Disassembler: 5826 1.1 jruoho 5827 1.1 jruoho Implemented support for the ACPI 3.0 Timer operator. 5828 1.1 jruoho 5829 1.1 jruoho Fixed a problem where the Default() operator was inadvertently ignored in a 5830 1.1 jruoho Switch/Case block. This was a problem in the translation of the Switch 5831 1.1 jruoho statement to If...Else pairs. 5832 1.1 jruoho 5833 1.1 jruoho Added support to allow a standalone Return operator, with no parentheses (or 5834 1.1 jruoho operands). 5835 1.1 jruoho 5836 1.1 jruoho Fixed a problem with code generation for the ElseIf operator where the 5837 1.1 jruoho translated Else...If parse tree was improperly constructed leading to the 5838 1.1 jruoho loss of some code. 5839 1.1 jruoho 5840 1.1 jruoho ---------------------------------------- 5841 1.1 jruoho 22 September 2004. Summary of changes for version 20040922: 5842 1.1 jruoho 5843 1.1 jruoho 1) ACPI CA Core Subsystem: 5844 1.1 jruoho 5845 1.1 jruoho Fixed a problem with the implementation of the LNot() operator where "Ones" 5846 1.1 jruoho was not returned for the TRUE case. Changed the code to return Ones instead 5847 1.1 jruoho of (!Arg) which was usually 1. This change affects iASL constant folding for 5848 1.1 jruoho this operator also. 5849 1.1 jruoho 5850 1.1 jruoho Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was not 5851 1.1 jruoho initialized properly -- Now zero the entire buffer in this case where the 5852 1.1 jruoho buffer already exists. 5853 1.1 jruoho 5854 1.1 jruoho Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32 5855 1.1 jruoho Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all 5856 1.1 jruoho related code considerably. This will require changes/updates to all OS 5857 1.1 jruoho interface layers (OSLs.) 5858 1.1 jruoho 5859 1.1 jruoho Implemented a new external interface, AcpiInstallExceptionHandler, to allow 5860 1.1 jruoho a system exception handler to be installed. This handler is invoked upon any 5861 1.1 jruoho run-time exception that occurs during control method execution. 5862 1.1 jruoho 5863 1.1 jruoho Added support for the DSDT in AcpiTbFindTable. This allows the 5864 1.1 jruoho DataTableRegion() operator to access the local copy of the DSDT. 5865 1.1 jruoho 5866 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5867 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5868 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5869 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5870 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5871 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5872 1.1 jruoho the compiler options used during generation. 5873 1.1 jruoho 5874 1.1 jruoho Previous Release: 5875 1.1 jruoho Non-Debug Version: 77.8K Code, 11.4K Data, 89.2K Total 5876 1.1 jruoho Debug Version: 164.2K Code, 68.2K Data, 232.4K Total 5877 1.1 jruoho Current Release: 5878 1.1 jruoho Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total 5879 1.1 jruoho Debug Version: 164.5K Code, 68.3K Data, 232.8K Total 5880 1.1 jruoho 5881 1.1 jruoho 5882 1.1 jruoho 2) iASL Compiler/Disassembler: 5883 1.1 jruoho 5884 1.1 jruoho Fixed a problem with constant folding and the LNot operator. LNot was 5885 1.1 jruoho returning 1 in the TRUE case, not Ones as per the ACPI specification. This 5886 1.1 jruoho could result in the generation of an incorrect folded/reduced constant. 5887 1.1 jruoho 5888 1.1 jruoho End-Of-File is now allowed within a "//"-style comment. A parse error no 5889 1.1 jruoho longer occurs if such a comment is at the very end of the input ASL source 5890 1.1 jruoho file. 5891 1.1 jruoho 5892 1.1 jruoho Implemented the "-r" option to override the Revision in the table header. 5893 1.1 jruoho The initial use of this option will be to simplify the evaluation of the AML 5894 1.1 jruoho interpreter by allowing a single ASL source module to be compiled for either 5895 1.1 jruoho 32-bit or 64-bit integers. 5896 1.1 jruoho 5897 1.1 jruoho 5898 1.1 jruoho ---------------------------------------- 5899 1.1 jruoho 27 August 2004. Summary of changes for version 20040827: 5900 1.1 jruoho 5901 1.1 jruoho 1) ACPI CA Core Subsystem: 5902 1.1 jruoho 5903 1.1 jruoho - Implemented support for implicit object conversion in the non-numeric 5904 1.1 jruoho logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, and 5905 1.1 jruoho LNotEqual.) Any combination of Integers/Strings/Buffers may now be used; 5906 1.1 jruoho the second operand is implicitly converted on the fly to match the type of 5907 1.1 jruoho the first operand. For example: 5908 1.1 jruoho 5909 1.1 jruoho LEqual (Source1, Source2) 5910 1.1 jruoho 5911 1.1 jruoho Source1 and Source2 must each evaluate to an integer, a string, or a buffer. 5912 1.1 jruoho The data type of Source1 dictates the required type of Source2. Source2 is 5913 1.1 jruoho implicitly converted if necessary to match the type of Source1. 5914 1.1 jruoho 5915 1.1 jruoho - Updated and corrected the behavior of the string conversion support. The 5916 1.1 jruoho rules concerning conversion of buffers to strings (according to the ACPI 5917 1.1 jruoho specification) are as follows: 5918 1.1 jruoho 5919 1.1 jruoho ToDecimalString - explicit byte-wise conversion of buffer to string of 5920 1.1 jruoho decimal values (0-255) separated by commas. ToHexString - explicit byte-wise 5921 1.1 jruoho conversion of buffer to string of hex values (0-FF) separated by commas. 5922 1.1 jruoho ToString - explicit byte-wise conversion of buffer to string. Byte-by-byte 5923 1.1 jruoho copy with no transform except NULL terminated. Any other implicit buffer-to- 5924 1.1 jruoho string conversion - byte-wise conversion of buffer to string of hex values 5925 1.1 jruoho (0-FF) separated by spaces. 5926 1.1 jruoho 5927 1.1 jruoho - Fixed typo in definition of AcpiGbl_EnableInterpreterSlack. 5928 1.1 jruoho 5929 1.1 jruoho - Fixed a problem in AcpiNsGetPathnameLength where the returned length was 5930 1.1 jruoho one byte too short in the case of a node in the root scope. This could 5931 1.1 jruoho cause a fault during debug output. 5932 1.1 jruoho 5933 1.1 jruoho - Code and Data Size: Current and previous core subsystem library sizes are 5934 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5935 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5936 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5937 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5938 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5939 1.1 jruoho the compiler options used during generation. 5940 1.1 jruoho 5941 1.1 jruoho Previous Release: 5942 1.1 jruoho Non-Debug Version: 77.9K Code, 11.5K Data, 89.4K Total 5943 1.1 jruoho Debug Version: 164.1K Code, 68.3K Data, 232.4K Total 5944 1.1 jruoho Current Release: 5945 1.1 jruoho Non-Debug Version: 77.8K Code, 11.4K Data, 89.2K Total 5946 1.1 jruoho Debug Version: 164.2K Code, 68.2K Data, 232.4K Total 5947 1.1 jruoho 5948 1.1 jruoho 5949 1.1 jruoho 2) iASL Compiler/Disassembler: 5950 1.1 jruoho 5951 1.1 jruoho - Fixed a Linux generation error. 5952 1.1 jruoho 5953 1.1 jruoho 5954 1.1 jruoho ---------------------------------------- 5955 1.1 jruoho 16 August 2004. Summary of changes for version 20040816: 5956 1.1 jruoho 5957 1.1 jruoho 1) ACPI CA Core Subsystem: 5958 1.1 jruoho 5959 1.1 jruoho Designed and implemented support within the AML interpreter for the so- 5960 1.1 jruoho called "implicit return". This support returns the result of the last ASL 5961 1.1 jruoho operation within a control method, in the absence of an explicit Return() 5962 1.1 jruoho operator. A few machines depend on this behavior, even though it is not 5963 1.1 jruoho explicitly supported by the ASL language. It is optional support that can 5964 1.1 jruoho be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag. 5965 1.1 jruoho 5966 1.1 jruoho Removed support for the PCI_Config address space from the internal low level 5967 1.1 jruoho hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite). This 5968 1.1 jruoho support was not used internally, and would not work correctly anyway because 5969 1.1 jruoho the PCI bus number and segment number were not supported. There are 5970 1.1 jruoho separate interfaces for PCI configuration space access because of the unique 5971 1.1 jruoho interface. 5972 1.1 jruoho 5973 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 5974 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 5975 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5976 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 5977 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 5978 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 5979 1.1 jruoho the compiler options used during generation. 5980 1.1 jruoho 5981 1.1 jruoho Previous Release: 5982 1.1 jruoho Non-Debug Version: 78.0K Code, 11.5K Data, 89.5K Total 5983 1.1 jruoho Debug Version: 164.1K Code, 68.2K Data, 232.3K Total 5984 1.1 jruoho Current Release: 5985 1.1 jruoho Non-Debug Version: 77.9K Code, 11.5K Data, 89.4K Total 5986 1.1 jruoho Debug Version: 164.1K Code, 68.3K Data, 232.4K Total 5987 1.1 jruoho 5988 1.1 jruoho 5989 1.1 jruoho 2) iASL Compiler/Disassembler: 5990 1.1 jruoho 5991 1.1 jruoho Fixed a problem where constants in ASL expressions at the root level (not 5992 1.1 jruoho within a control method) could be inadvertently truncated during code 5993 1.1 jruoho generation. This problem was introduced in the 20040715 release. 5994 1.1 jruoho 5995 1.1 jruoho 5996 1.1 jruoho ---------------------------------------- 5997 1.1 jruoho 15 July 2004. Summary of changes for version 20040715: 5998 1.1 jruoho 5999 1.1 jruoho 1) ACPI CA Core Subsystem: 6000 1.1 jruoho 6001 1.1 jruoho Restructured the internal HW GPE interfaces to pass/track the current state 6002 1.1 jruoho of interrupts (enabled/disabled) in order to avoid possible deadlock and 6003 1.1 jruoho increase flexibility of the interfaces. 6004 1.1 jruoho 6005 1.1 jruoho Implemented a "lexicographical compare" for String and Buffer objects within 6006 1.1 jruoho the logical operators -- LGreater, LLess, LGreaterEqual, and LLessEqual -- 6007 1.1 jruoho as per further clarification to the ACPI specification. Behavior is similar 6008 1.1 jruoho to C library "strcmp". 6009 1.1 jruoho 6010 1.1 jruoho Completed a major reduction in CPU stack use for the AcpiGetFirmwareTable 6011 1.1 jruoho external function. In the 32-bit non-debug case, the stack use has been 6012 1.1 jruoho reduced from 168 bytes to 32 bytes. 6013 1.1 jruoho 6014 1.1 jruoho Deployed a new run-time configuration flag, AcpiGbl_EnableInterpreterSlack, 6015 1.1 jruoho whose purpose is to allow the AML interpreter to forgive certain bad AML 6016 1.1 jruoho constructs. Default setting is FALSE. 6017 1.1 jruoho 6018 1.1 jruoho Implemented the first use of AcpiGbl_EnableInterpreterSlack in the Field IO 6019 1.1 jruoho support code. If enabled, it allows field access to go beyond the end of a 6020 1.1 jruoho region definition if the field is within the region length rounded up to the 6021 1.1 jruoho next access width boundary (a common coding error.) 6022 1.1 jruoho 6023 1.1 jruoho Renamed OSD_HANDLER to ACPI_OSD_HANDLER, and OSD_EXECUTION_CALLBACK to 6024 1.1 jruoho ACPI_OSD_EXEC_CALLBACK for consistency with other ACPI symbols. Also, these 6025 1.1 jruoho symbols are lowercased by the latest version of the AcpiSrc tool. 6026 1.1 jruoho 6027 1.1 jruoho The prototypes for the PCI interfaces in acpiosxf.h have been updated to 6028 1.1 jruoho rename "Register" to simply "Reg" to prevent certain compilers from 6029 1.1 jruoho complaining. 6030 1.1 jruoho 6031 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6032 1.1 jruoho shown below.

This applies when using the -g or - 6112 1.1 jruoho d<nofilename> options. The compiler now looks for both strings as 6113 1.1 jruoho necessary. 6114 1.1 jruoho 6115 1.1 jruoho Fixed a problem with compiler namepath optimization where a namepath within 6116 1.1 jruoho the Scope() operator could not be optimized if the namepath was a subpath of 6117 1.1 jruoho the current scope path. 6118 1.1 jruoho 6119 1.1 jruoho ---------------------------------------- 6120 1.1 jruoho 27 May 2004. Summary of changes for version 20040527: 6121 1.1 jruoho 6122 1.1 jruoho 1) ACPI CA Core Subsystem: 6123 1.1 jruoho 6124 1.1 jruoho Completed a new design and implementation for EBDA (Extended BIOS Data Area) 6125 1.1 jruoho support in the RSDP scan code. The original code improperly scanned for the 6126 1.1 jruoho EBDA by simply scanning from memory location 0 to 0x400. The correct method 6127 1.1 jruoho is to first obtain the EBDA pointer from within the BIOS data area, then 6128 1.1 jruoho scan 1K of memory starting at the EBDA pointer. There appear to be few if 6129 1.1 jruoho any machines that place the RSDP in the EBDA, however. 6130 1.1 jruoho 6131 1.1 jruoho Integrated a fix for a possible fault during evaluation of BufferField 6132 1.1 jruoho arguments. Obsolete code that was causing the problem was removed. 6133 1.1 jruoho 6134 1.1 jruoho Found and fixed a problem in the Field Support Code where data could be 6135 1.1 jruoho corrupted on a bit field read that starts on an aligned boundary but does 6136 1.1 jruoho not end on an aligned boundary. Merged the read/write "datum length" 6137 1.1 jruoho calculation code into a common procedure. 6138 1.1 jruoho 6139 1.1 jruoho Rolled in a couple of changes to the FreeBSD-specific header. 6140 1.1 jruoho 6141 1.1 jruoho 6142 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6143 1.1 jruoho shown below.

Summary of changes for version 20040514: 6165 1.1 jruoho 6166 1.1 jruoho 1) ACPI CA Core Subsystem: 6167 1.1 jruoho 6168 1.1 jruoho Fixed a problem where hardware GPE enable bits sometimes not set properly 6169 1.1 jruoho during and after GPE method execution. Result of 04/27 changes. 6170 1.1 jruoho 6171 1.1 jruoho Removed extra "clear all GPEs" when sleeping/waking. 6172 1.1 jruoho 6173 1.1 jruoho Removed AcpiHwEnableGpe and AcpiHwDisableGpe, replaced by the single 6174 1.1 jruoho AcpiHwWriteGpeEnableReg. Changed a couple of calls to the functions above to 6175 1.1 jruoho the new AcpiEv* calls as appropriate. 6176 1.1 jruoho 6177 1.1 jruoho ACPI_OS_NAME was removed from the OS-specific headers. The default name is 6178 1.1 jruoho now "Microsoft Windows NT" for maximum compatibility. However this can be 6179 1.1 jruoho changed by modifying the acconfig.h file. 6180 1.1 jruoho 6181 1.1 jruoho Allow a single invocation of AcpiInstallNotifyHandler for a handler that 6182 1.1 jruoho traps both types of notifies (System, Device). Use ACPI_ALL_NOTIFY flag. 6183 1.1 jruoho 6184 1.1 jruoho Run _INI methods on ThermalZone objects. This is against the ACPI 6185 1.1 jruoho specification, but there is apparently ASL code in the field that has these 6186 1.1 jruoho _INI methods, and apparently "other" AML interpreters execute them. 6187 1.1 jruoho 6188 1.1 jruoho Performed a full 16/32/64 bit lint that resulted in some small changes. 6189 1.1 jruoho 6190 1.1 jruoho Added a sleep simulation command to the AML debugger to test sleep code. 6191 1.1 jruoho 6192 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6193 1.1 jruoho shown below.

Summary of changes for version 20040427: 6209 1.1 jruoho 6210 1.1 jruoho 1) ACPI CA Core Subsystem: 6211 1.1 jruoho 6212 1.1 jruoho Completed a major overhaul of the GPE handling within ACPI CA. There are 6213 1.1 jruoho now three types of GPEs: wake-only, runtime-only, and combination wake/run. 6214 1.1 jruoho The only GPEs allowed to be combination wake/run are for button-style 6215 1.1 jruoho devices such as a control-method power button, control-method sleep button, 6216 1.1 jruoho or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are not 6217 1.1 jruoho referenced by any _PRW methods are marked for "runtime" and hardware 6218 1.1 jruoho enabled. Any GPE that is referenced by a _PRW method is marked for "wake" 6219 1.1 jruoho (and disabled at runtime). However, at sleep time, only those GPEs that 6220 1.1 jruoho have been specifically enabled for wake via the AcpiEnableGpe interface will 6221 1.1 jruoho actually be hardware enabled. 6222 1.1 jruoho 6223 1.1 jruoho A new external interface has been added, AcpiSetGpeType(), that is meant to 6224 1.1 jruoho be used by device drivers to force a GPE to a particular type. It will be 6225 1.1 jruoho especially useful for the drivers for the button devices mentioned above. 6226 1.1 jruoho 6227 1.1 jruoho Completed restructuring of the ACPI CA initialization sequence so that 6228 1.1 jruoho default operation region handlers are installed before GPEs are initialized 6229 1.1 jruoho and the _PRW methods are executed. This will prevent errors when the _PRW 6230 1.1 jruoho methods attempt to access system memory or I/O space. 6231 1.1 jruoho 6232 1.1 jruoho GPE enable/disable no longer reads the GPE enable register. We now keep the 6233 1.1 jruoho enable info for runtime and wake separate and in the GPE_EVENT_INFO. We 6234 1.1 jruoho thus no longer depend on the hardware to maintain these bits. 6235 1.1 jruoho 6236 1.1 jruoho Always clear the wake status and fixed/GPE status bits before sleep, even 6237 1.1 jruoho for state S5. 6238 1.1 jruoho 6239 1.1 jruoho Improved the AML debugger output for displaying the GPE blocks and their 6240 1.1 jruoho current status. 6241 1.1 jruoho 6242 1.1 jruoho Added new strings for the _OSI method, of the form "Windows 2001 SPx" where 6243 1.1 jruoho x = 0,1,2,3,4. 6244 1.1 jruoho 6245 1.1 jruoho Fixed a problem where the physical address was incorrectly calculated when 6246 1.1 jruoho the Load() operator was used to directly load from an Operation Region (vs. 6247 1.1 jruoho loading from a Field object.) Also added check for minimum table length for 6248 1.1 jruoho this case. 6249 1.1 jruoho 6250 1.1 jruoho Fix for multiple mutex acquisition. Restore original thread SyncLevel on 6251 1.1 jruoho mutex release. 6252 1.1 jruoho 6253 1.1 jruoho Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for 6254 1.1 jruoho consistency with the other fields returned. 6255 1.1 jruoho 6256 1.1 jruoho Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such 6257 1.1 jruoho structure for each GPE in the system, so the size of this structure is 6258 1.1 jruoho important. 6259 1.1 jruoho 6260 1.1 jruoho CPU stack requirement reduction: Cleaned up the method execution and object 6261 1.1 jruoho evaluation paths so that now a parameter structure is passed, instead of 6262 1.1 jruoho copying the various method parameters over and over again. 6263 1.1 jruoho 6264 1.1 jruoho In evregion.c: Correctly exit and reenter the interpreter region if and 6265 1.1 jruoho only if dispatching an operation region request to a user-installed handler. 6266 1.1 jruoho Do not exit/reenter when dispatching to a default handler (e.g., default 6267 1.1 jruoho system memory or I/O handlers) 6268 1.1 jruoho 6269 1.1 jruoho 6270 1.1 jruoho Notes for updating drivers for the new GPE support. The following changes 6271 1.1 jruoho must be made to ACPI-related device drivers that are attached to one or more 6272 1.1 jruoho GPEs: (This information will be added to the ACPI CA Programmer Reference.) 6273 1.1 jruoho 6274 1.1 jruoho 1) AcpiInstallGpeHandler no longer automatically enables the GPE, you must 6275 1.1 jruoho explicitly call AcpiEnableGpe. 6276 1.1 jruoho 2) There is a new interface called AcpiSetGpeType. This should be called 6277 1.1 jruoho before enabling the GPE. Also, this interface will automatically disable 6278 1.1 jruoho the GPE if it is currently enabled. 6279 1.1 jruoho 3) AcpiEnableGpe no longer supports a GPE type flag. 6280 1.1 jruoho 6281 1.1 jruoho Specific drivers that must be changed: 6282 1.1 jruoho 1) EC driver: 6283 1.1 jruoho AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED, 6284 1.1 jruoho AeGpeHandler, NULL); 6285 1.1 jruoho AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME); 6286 1.1 jruoho AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR); 6287 1.1 jruoho 6288 1.1 jruoho 2) Button Drivers (Power, Lid, Sleep): 6289 1.1 jruoho Run _PRW method under parent device 6290 1.1 jruoho If _PRW exists: /* This is a control-method button */ 6291 1.1 jruoho Extract GPE number and possibly GpeDevice 6292 1.1 jruoho AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN); 6293 1.1 jruoho AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR); 6294 1.1 jruoho 6295 1.1 jruoho For all other devices that have _PRWs, we automatically set the GPE type to 6296 1.1 jruoho ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled. This 6297 1.1 jruoho must be done on a selective basis, usually requiring some kind of user app 6298 1.1 jruoho to allow the user to pick the wake devices. 6299 1.1 jruoho 6300 1.1 jruoho 6301 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6302 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 6303 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6304 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 6305 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 6306 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 6307 1.1 jruoho the compiler options used during generation. 6308 1.1 jruoho 6309 1.1 jruoho Previous Release: 6310 1.1 jruoho Non-Debug Version: 77.0K Code, 11.4K Data, 88.4K Total 6311 1.1 jruoho Debug Version: 161.0K Code, 66.3K Data, 227.3K Total 6312 1.1 jruoho Current Release: 6313 1.1 jruoho 6314 1.1 jruoho Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 6315 1.1 jruoho Debug Version: 162.9K Code, 67.0K Data, 229.9K Total 6316 1.1 jruoho 6317 1.1 jruoho 6318 1.1 jruoho 6319 1.1 jruoho ---------------------------------------- 6320 1.1 jruoho 02 April 2004. Summary of changes for version 20040402: 6321 1.1 jruoho 6322 1.1 jruoho 1) ACPI CA Core Subsystem: 6323 1.1 jruoho 6324 1.1 jruoho Fixed an interpreter problem where an indirect store through an ArgX 6325 1.1 jruoho parameter was incorrectly applying the "implicit conversion rules" during 6326 1.1 jruoho the store. From the ACPI specification: "If the target is a method local or 6327 1.1 jruoho argument (LocalX or ArgX), no conversion is performed and the result is 6328 1.1 jruoho stored directly to the target". The new behavior is to disable implicit 6329 1.1 jruoho conversion during ALL stores to an ArgX. 6330 1.1 jruoho 6331 1.1 jruoho Changed the behavior of the _PRW method scan to ignore any and all errors 6332 1.1 jruoho returned by a given _PRW. This prevents the scan from aborting from the 6333 1.1 jruoho failure of any single _PRW. 6334 1.1 jruoho 6335 1.1 jruoho Moved the runtime configuration parameters from the global init procedure to 6336 1.1 jruoho static variables in acglobal.h. This will allow the host to override the 6337 1.1 jruoho default values easily. 6338 1.1 jruoho 6339 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6340 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 6341 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6342 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 6343 1.1 jruoho debug output trace mechanism and has a much larger code and data size.

However, External() statements are not 6358 1.1 jruoho generated automatically for unresolved symbols at this time. This is a 6359 1.1 jruoho planned feature for future implementation. 6360 1.1 jruoho 6361 1.1 jruoho Fixed a scoping problem in the disassembler that occurs when the type of the 6362 1.1 jruoho target of a Scope() operator is overridden. This problem caused an 6363 1.1 jruoho incorrectly nested internal namespace to be constructed. 6364 1.1 jruoho 6365 1.1 jruoho Any warnings or errors that are emitted during disassembly are now commented 6366 1.1 jruoho out automatically so that the resulting file can be recompiled without any 6367 1.1 jruoho hand editing. 6368 1.1 jruoho 6369 1.1 jruoho ---------------------------------------- 6370 1.1 jruoho 26 March 2004. Summary of changes for version 20040326: 6371 1.1 jruoho 6372 1.1 jruoho 1) ACPI CA Core Subsystem: 6373 1.1 jruoho 6374 1.1 jruoho Implemented support for "wake" GPEs via interaction between GPEs and the 6375 1.1 jruoho _PRW methods. Every GPE that is pointed to by one or more _PRWs is 6376 1.1 jruoho identified as a WAKE GPE and by default will no longer be enabled at 6377 1.1 jruoho runtime. Previously, we were blindly enabling all GPEs with a corresponding 6378 1.1 jruoho _Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway. We 6379 1.1 jruoho believe this has been the cause of thousands of "spurious" GPEs on some 6380 1.1 jruoho systems. 6381 1.1 jruoho 6382 1.1 jruoho This new GPE behavior is can be reverted to the original behavior (enable 6383 1.1 jruoho ALL GPEs at runtime) via a runtime flag. 6384 1.1 jruoho 6385 1.1 jruoho Fixed a problem where aliased control methods could not access objects 6386 1.1 jruoho properly. The proper scope within the namespace was not initialized 6387 1.1 jruoho (transferred to the target of the aliased method) before executing the 6388 1.1 jruoho target method. 6389 1.1 jruoho 6390 1.1 jruoho Fixed a potential race condition on internal object deletion on the return 6391 1.1 jruoho object in AcpiEvaluateObject. 6392 1.1 jruoho 6393 1.1 jruoho Integrated a fix for resource descriptors where both _MEM and _MTP were 6394 1.1 jruoho being extracted instead of just _MEM. (i.e. bitmask was incorrectly too 6395 1.1 jruoho wide, 0x0F instead of 0x03.) 6396 1.1 jruoho 6397 1.1 jruoho Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, preventing a 6398 1.1 jruoho fault in some cases. 6399 1.1 jruoho 6400 1.1 jruoho Updated Notify() values for debug statements in evmisc.c 6401 1.1 jruoho 6402 1.1 jruoho Return proper status from AcpiUtMutexInitialize, not just simply AE_OK. 6403 1.1 jruoho 6404 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6405 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 6406 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6407 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 6408 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 6409 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 6410 1.1 jruoho the compiler options used during generation. 6411 1.1 jruoho 6412 1.1 jruoho Previous Release: 6413 1.1 jruoho 6414 1.1 jruoho Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total 6415 1.1 jruoho Debug Version: 160.3K Code, 66.0K Data, 226.3K Total 6416 1.1 jruoho Current Release: 6417 1.1 jruoho Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total 6418 1.1 jruoho Debug Version: 160.8K Code, 66.1K Data, 226.9K Total 6419 1.1 jruoho 6420 1.1 jruoho ---------------------------------------- 6421 1.1 jruoho 11 March 2004. Summary of changes for version 20040311: 6422 1.1 jruoho 6423 1.1 jruoho 1) ACPI CA Core Subsystem: 6424 1.1 jruoho 6425 1.1 jruoho Fixed a problem where errors occurring during the parse phase of control 6426 1.1 jruoho method execution did not abort cleanly. For example, objects created and 6427 1.1 jruoho installed in the namespace were not deleted. This caused all subsequent 6428 1.1 jruoho invocations of the method to return the AE_ALREADY_EXISTS exception. 6429 1.1 jruoho 6430 1.1 jruoho Implemented a mechanism to force a control method to "Serialized" execution 6431 1.1 jruoho if the method attempts to create namespace objects. (The root of the 6432 1.1 jruoho AE_ALREADY_EXISTS problem.) 6433 1.1 jruoho 6434 1.1 jruoho Implemented support for the predefined _OSI "internal" control method. 6435 1.1 jruoho Initial supported strings are "Linux", "Windows 2000", "Windows 2001", and 6436 1.1 jruoho "Windows 2001.1", and can be easily upgraded for new strings as necessary. 6437 1.1 jruoho This feature will allow "other" operating systems to execute the fully 6438 1.1 jruoho tested, "Windows" code path through the ASL code 6439 1.1 jruoho 6440 1.1 jruoho Global Lock Support: Now allows multiple acquires and releases with any 6441 1.1 jruoho internal thread. Removed concept of "owning thread" for this special mutex. 6442 1.1 jruoho 6443 1.1 jruoho Fixed two functions that were inappropriately declaring large objects on the 6444 1.1 jruoho CPU stack: PsParseLoop, NsEvaluateRelative. Reduces the stack usage during 6445 1.1 jruoho method execution considerably. 6446 1.1 jruoho 6447 1.1 jruoho Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the 6448 1.1 jruoho S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT. 6449 1.1 jruoho 6450 1.1 jruoho Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs 6451 1.1 jruoho defined on the machine. 6452 1.1 jruoho 6453 1.1 jruoho Implemented two runtime options: One to force all control method execution 6454 1.1 jruoho to "Serialized" to mimic Windows behavior, another to disable _OSI support 6455 1.1 jruoho if it causes problems on a given machine. 6456 1.1 jruoho 6457 1.1 jruoho Code and Data Size: Current and previous core subsystem library sizes are 6458 1.1 jruoho shown below. These are the code and data sizes for the acpica.lib produced 6459 1.1 jruoho by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6460 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code includes the 6461 1.1 jruoho debug output trace mechanism and has a much larger code and data size. Note 6462 1.1 jruoho that these values will vary depending on the efficiency of the compiler and 6463 1.1 jruoho the compiler options used during generation. 6464 1.1 jruoho 6465 1.1 jruoho Previous Release: 6466 1.1 jruoho Non-Debug Version: 74.8K Code, 10.1K Data, 84.9K Total 6467 1.1 jruoho Debug Version: 158.7K Code, 65.1K Data, 223.8K Total 6468 1.1 jruoho Current Release: 6469 1.1 jruoho Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total 6470 1.1 jruoho Debug Version: 160.3K Code, 66.0K Data, 226.3K Total 6471 1.1 jruoho 6472 1.1 jruoho 2) iASL Compiler/Disassembler: 6473 1.1 jruoho 6474 1.1 jruoho Fixed an array size problem for FreeBSD that would cause the compiler to 6475 1.1 jruoho fault. 6476 1.1 jruoho 6477 1.1 jruoho ---------------------------------------- 6478 1.1 jruoho 20 February 2004. Summary of changes for version 20040220: 6479 1.1 jruoho 6480 1.1 jruoho 6481 1.1 jruoho 1) ACPI CA Core Subsystem: 6482 1.1 jruoho 6483 1.1 jruoho Implemented execution of _SxD methods for Device objects in the 6484 1.1 jruoho GetObjectInfo interface. 6485 1.1 jruoho 6486 1.1 jruoho Fixed calls to _SST method to pass the correct arguments. 6487 1.1 jruoho 6488 1.1 jruoho Added a call to _SST on wake to restore to "working" state. 6489 1.1 jruoho 6490 1.1 jruoho Check for End-Of-Buffer failure case in the WalkResources interface. 6491 1.1 jruoho 6492 1.1 jruoho Integrated fix for 64-bit alignment issue in acglobal.h by moving two 6493 1.1 jruoho structures to the beginning of the file. 6494 1.1 jruoho 6495 1.1 jruoho After wake, clear GPE status register(s) before enabling GPEs. 6496 1.1 jruoho 6497 1.1 jruoho After wake, clear/enable power button. (Perhaps we should clear/enable all 6498 1.1 jruoho fixed events upon wake.) 6499 1.1 jruoho 6500 1.1 jruoho Fixed a couple of possible memory leaks in the Namespace manager. 6501 1.1 jruoho 6502 1.1 jruoho Integrated latest acnetbsd.h file. 6503 1.1 jruoho 6504 1.1 jruoho ---------------------------------------- 6505 1.1 jruoho 11 February 2004. Summary of changes for version 20040211: 6506 1.1 jruoho 6507 1.1 jruoho 6508 1.1 jruoho 1) ACPI CA Core Subsystem: 6509 1.1 jruoho 6510 1.1 jruoho Completed investigation and implementation of the call-by-reference 6511 1.1 jruoho mechanism for control method arguments. 6512 1.1 jruoho 6513 1.1 jruoho Fixed a problem where a store of an object into an indexed package could 6514 1.1 jruoho fail if the store occurs within a different method than the method that 6515 1.1 jruoho created the package. 6516 1.1 jruoho 6517 1.1 jruoho Fixed a problem where the ToDecimal operator could return incorrect results. 6518 1.1 jruoho 6519 1.1 jruoho Fixed a problem where the CopyObject operator could fail on some of the more 6520 1.1 jruoho obscure objects (e.g., Reference objects.) 6521 1.1 jruoho 6522 1.1 jruoho Improved the output of the Debug object to display buffer, package, and 6523 1.1 jruoho index objects. 6524 1.1 jruoho 6525 1.1 jruoho Fixed a problem where constructs of the form "RefOf (ArgX)" did not return 6526 1.1 jruoho the expected result. 6527 1.1 jruoho 6528 1.1 jruoho Added permanent ACPI_REPORT_ERROR macros for all instances of the 6529 1.1 jruoho ACPI_AML_INTERNAL exception. 6530 1.1 jruoho 6531 1.1 jruoho Integrated latest version of acfreebsd.h 6532 1.1 jruoho 6533 1.1 jruoho ---------------------------------------- 6534 1.1 jruoho 16 January 2004. Summary of changes for version 20040116: 6535 1.1 jruoho 6536 1.1 jruoho The purpose of this release is primarily to update the copyright years in 6537 1.1 jruoho each module, thus causing a huge number of diffs. There are a few small 6538 1.1 jruoho functional changes, however. 6539 1.1 jruoho 6540 1.1 jruoho 1) ACPI CA Core Subsystem: 6541 1.1 jruoho 6542 1.1 jruoho Improved error messages when there is a problem finding one or more of the 6543 1.1 jruoho required base ACPI tables 6544 1.1 jruoho 6545 1.1 jruoho Reintroduced the definition of APIC_HEADER in actbl.h 6546 1.1 jruoho 6547 1.1 jruoho Changed definition of MADT_ADDRESS_OVERRIDE to 64 bits (actbl.h) 6548 1.1 jruoho 6549 1.1 jruoho Removed extraneous reference to NewObj in dsmthdat.c 6550 1.1 jruoho 6551 1.1 jruoho 2) iASL compiler 6552 1.1 jruoho 6553 1.1 jruoho Fixed a problem introduced in December that disabled the correct disassembly 6554 1.1 jruoho of Resource Templates 6555 1.1 jruoho 6556 1.1 jruoho 6557 1.1 jruoho ---------------------------------------- 6558 1.1 jruoho 03 December 2003. Summary of changes for version 20031203: 6559 1.1 jruoho 6560 1.1 jruoho 1) ACPI CA Core Subsystem: 6561 1.1 jruoho 6562 1.1 jruoho Changed the initialization of Operation Regions during subsystem 6563 1.1 jruoho init to perform two entire walks of the ACPI namespace; The first 6564 1.1 jruoho to initialize the regions themselves, the second to execute the 6565 1.1 jruoho _REG methods. This fixed some interdependencies across _REG 6566 1.1 jruoho methods found on some machines. 6567 1.1 jruoho 6568 1.1 jruoho Fixed a problem where a Store(Local0, Local1) could simply update 6569 1.1 jruoho the object reference count, and not create a new copy of the 6570 1.1 jruoho object if the Local1 is uninitialized. 6571 1.1 jruoho 6572 1.1 jruoho Implemented support for the _SST reserved method during sleep 6573 1.1 jruoho transitions. 6574 1.1 jruoho 6575 1.1 jruoho Implemented support to clear the SLP_TYP and SLP_EN bits when 6576 1.1 jruoho waking up, this is apparently required by some machines. 6577 1.1 jruoho 6578 1.1 jruoho When sleeping, clear the wake status only if SleepState is not S5. 6579 1.1 jruoho 6580 1.1 jruoho Fixed a problem in AcpiRsExtendedIrqResource() where an incorrect 6581 1.1 jruoho pointer arithmetic advanced a string pointer too far. 6582 1.1 jruoho 6583 1.1 jruoho Fixed a problem in AcpiTbGetTablePtr() where a garbage pointer 6584 1.1 jruoho could be returned if the requested table has not been loaded. 6585 1.1 jruoho 6586 1.1 jruoho Within the support for IRQ resources, restructured the handling of 6587 1.1 jruoho the active and edge/level bits. 6588 1.1 jruoho 6589 1.1 jruoho Fixed a few problems in AcpiPsxExecute() where memory could be 6590 1.1 jruoho leaked under certain error conditions. 6591 1.1 jruoho 6592 1.1 jruoho Improved error messages for the cases where the ACPI mode could 6593 1.1 jruoho not be entered. 6594 1.1 jruoho 6595 1.1 jruoho Code and Data Size: Current and previous core subsystem library 6596 1.1 jruoho sizes are shown below. These are the code and data sizes for the 6597 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6598 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 6599 1.1 jruoho debug version of the code includes the debug output trace 6600 1.1 jruoho mechanism and has a much larger code and data size. Note that 6601 1.1 jruoho these values will vary depending on the efficiency of the compiler 6602 1.1 jruoho and the compiler options used during generation. 6603 1.1 jruoho 6604 1.1 jruoho Previous Release (20031029): 6605 1.1 jruoho Non-Debug Version: 74.4K Code, 10.1K Data, 84.5K Total 6606 1.1 jruoho Debug Version: 158.3K Code, 65.0K Data, 223.3K Total 6607 1.1 jruoho Current Release: 6608 1.1 jruoho Non-Debug Version: 74.8K Code, 10.1K Data, 84.9K Total 6609 1.1 jruoho Debug Version: 158.7K Code, 65.1K Data, 223.8K Total 6610 1.1 jruoho 6611 1.1 jruoho 2) iASL Compiler/Disassembler: 6612 1.1 jruoho 6613 1.1 jruoho Implemented a fix for the iASL disassembler where a bad index was 6614 1.1 jruoho generated. This was most noticeable on 64-bit platforms 6615 1.1 jruoho 6616 1.1 jruoho 6617 1.1 jruoho ---------------------------------------- 6618 1.1 jruoho 29 October 2003. Summary of changes for version 20031029: 6619 1.1 jruoho 6620 1.1 jruoho 1) ACPI CA Core Subsystem: 6621 1.1 jruoho 6622 1.1 jruoho 6623 1.1 jruoho Fixed a problem where a level-triggered GPE with an associated 6624 1.1 jruoho _Lxx control method was incorrectly cleared twice. 6625 1.1 jruoho 6626 1.1 jruoho Fixed a problem with the Field support code where an access can 6627 1.1 jruoho occur beyond the end-of-region if the field is non-aligned but 6628 1.1 jruoho extends to the very end of the parent region (resulted in an 6629 1.1 jruoho AE_AML_REGION_LIMIT exception.) 6630 1.1 jruoho 6631 1.1 jruoho Fixed a problem with ACPI Fixed Events where an RT Clock handler 6632 1.1 jruoho would not get invoked on an RTC event. The RTC event bitmasks for 6633 1.1 jruoho the PM1 registers were not being initialized properly. 6634 1.1 jruoho 6635 1.1 jruoho Implemented support for executing _STA and _INI methods for 6636 1.1 jruoho Processor objects. Although this is currently not part of the 6637 1.1 jruoho ACPI specification, there is existing ASL code that depends on the 6638 1.1 jruoho init-time execution of these methods. 6639 1.1 jruoho 6640 1.1 jruoho Implemented and deployed a GetDescriptorName function to decode 6641 1.1 jruoho the various types of internal descriptors. Guards against null 6642 1.1 jruoho descriptors during debug output also. 6643 1.1 jruoho 6644 1.1 jruoho Implemented and deployed a GetNodeName function to extract the 4- 6645 1.1 jruoho character namespace node name. This function simplifies the debug 6646 1.1 jruoho and error output, as well as guarding against null pointers during 6647 1.1 jruoho output. 6648 1.1 jruoho 6649 1.1 jruoho Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to 6650 1.1 jruoho simplify the debug and error output of 64-bit integers. This 6651 1.1 jruoho macro replaces the HIDWORD and LODWORD macros for dumping these 6652 1.1 jruoho integers. 6653 1.1 jruoho 6654 1.1 jruoho Updated the implementation of the Stall() operator to only call 6655 1.1 jruoho AcpiOsStall(), and also return an error if the operand is larger 6656 1.1 jruoho than 255. This preserves the required behavior of not 6657 1.1 jruoho relinquishing the processor, as would happen if AcpiOsSleep() was 6658 1.1 jruoho called for "long stalls". 6659 1.1 jruoho 6660 1.1 jruoho Constructs of the form "Store(LocalX,LocalX)" where LocalX is not 6661 1.1 jruoho initialized are now treated as NOOPs. 6662 1.1 jruoho 6663 1.1 jruoho Cleaned up a handful of warnings during 64-bit generation. 6664 1.1 jruoho 6665 1.1 jruoho Fixed a reported error where and incorrect GPE number was passed 6666 1.1 jruoho to the GPE dispatch handler. This value is only used for error 6667 1.1 jruoho output, however. Used this opportunity to clean up and streamline 6668 1.1 jruoho the GPE dispatch code. 6669 1.1 jruoho 6670 1.1 jruoho Code and Data Size: Current and previous core subsystem library 6671 1.1 jruoho sizes are shown below. These are the code and data sizes for the 6672 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6673 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 6674 1.1 jruoho 6675 1.1 jruoho debug version of the code includes the debug output trace 6676 1.1 jruoho mechanism and has a much larger code and data size. Note that 6677 1.1 jruoho these values will vary depending on the efficiency of the compiler 6678 1.1 jruoho and the compiler options used during generation. 6679 1.1 jruoho 6680 1.1 jruoho Previous Release (20031002): 6681 1.1 jruoho Non-Debug Version: 74.1K Code, 9.7K Data, 83.8K Total 6682 1.1 jruoho Debug Version: 157.9K Code, 64.8K Data, 222.7K Total 6683 1.1 jruoho Current Release: 6684 1.1 jruoho Non-Debug Version: 74.4K Code, 10.1K Data, 84.5K Total 6685 1.1 jruoho Debug Version: 158.3K Code, 65.0K Data, 223.3K Total 6686 1.1 jruoho 6687 1.1 jruoho 6688 1.1 jruoho 2) iASL Compiler/Disassembler: 6689 1.1 jruoho 6690 1.1 jruoho Updated the iASL compiler to return an error if the operand to the 6691 1.1 jruoho Stall() operator is larger than 255. 6692 1.1 jruoho 6693 1.1 jruoho 6694 1.1 jruoho ---------------------------------------- 6695 1.1 jruoho 02 October 2003. Summary of changes for version 20031002: 6696 1.1 jruoho 6697 1.1 jruoho 6698 1.1 jruoho 1) ACPI CA Core Subsystem: 6699 1.1 jruoho 6700 1.1 jruoho Fixed a problem with Index Fields where the index was not 6701 1.1 jruoho incremented for fields that require multiple writes to the 6702 1.1 jruoho index/data registers (Fields that are wider than the data 6703 1.1 jruoho register.) 6704 1.1 jruoho 6705 1.1 jruoho Fixed a problem with all Field objects where a write could go 6706 1.1 jruoho beyond the end-of-field if the field was larger than the access 6707 1.1 jruoho granularity and therefore required multiple writes to complete the 6708 1.1 jruoho request. An extra write beyond the end of the field could happen 6709 1.1 jruoho inadvertently. 6710 1.1 jruoho 6711 1.1 jruoho Fixed a problem with Index Fields where a BUFFER_OVERFLOW error 6712 1.1 jruoho would incorrectly be returned if the width of the Data Register 6713 1.1 jruoho was larger than the specified field access width. 6714 1.1 jruoho 6715 1.1 jruoho Completed fixes for LoadTable() and Unload() and verified their 6716 1.1 jruoho operation. Implemented full support for the "DdbHandle" object 6717 1.1 jruoho throughout the ACPI CA subsystem. 6718 1.1 jruoho 6719 1.1 jruoho Implemented full support for the MADT and ECDT tables in the ACPI 6720 1.1 jruoho CA header files. Even though these tables are not directly 6721 1.1 jruoho consumed by ACPI CA, the header definitions are useful for ACPI 6722 1.1 jruoho device drivers. 6723 1.1 jruoho 6724 1.1 jruoho Integrated resource descriptor fixes posted to the Linux ACPI 6725 1.1 jruoho list. This included checks for minimum descriptor length, and 6726 1.1 jruoho support for trailing NULL strings within descriptors that have 6727 1.1 jruoho optional string elements. 6728 1.1 jruoho 6729 1.1 jruoho Code and Data Size: Current and previous core subsystem library 6730 1.1 jruoho sizes are shown below. These are the code and data sizes for the 6731 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6732 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 6733 1.1 jruoho debug version of the code includes the debug output trace 6734 1.1 jruoho mechanism and has a much larger code and data size. Note that 6735 1.1 jruoho these values will vary depending on the efficiency of the compiler 6736 1.1 jruoho and the compiler options used during generation. 6737 1.1 jruoho 6738 1.1 jruoho Previous Release (20030918): 6739 1.1 jruoho Non-Debug Version: 73.9K Code, 9.7K Data, 83.6K Total 6740 1.1 jruoho Debug Version: 157.3K Code, 64.5K Data, 221.8K Total 6741 1.1 jruoho Current Release: 6742 1.1 jruoho Non-Debug Version: 74.1K Code, 9.7K Data, 83.8K Total 6743 1.1 jruoho Debug Version: 157.9K Code, 64.8K Data, 222.7K Total 6744 1.1 jruoho 6745 1.1 jruoho 6746 1.1 jruoho 2) iASL Compiler: 6747 1.1 jruoho 6748 1.1 jruoho Implemented detection of non-ASCII characters within the input 6749 1.1 jruoho source ASL file. This catches attempts to compile binary (AML) 6750 1.1 jruoho files early in the compile, with an informative error message. 6751 1.1 jruoho 6752 1.1 jruoho Fixed a problem where the disassembler would fault if the output 6753 1.1 jruoho filename could not be generated or if the output file could not be 6754 1.1 jruoho opened. 6755 1.1 jruoho 6756 1.1 jruoho ---------------------------------------- 6757 1.1 jruoho 18 September 2003. Summary of changes for version 20030918: 6758 1.1 jruoho 6759 1.1 jruoho 6760 1.1 jruoho 1) ACPI CA Core Subsystem: 6761 1.1 jruoho 6762 1.1 jruoho Found and fixed a longstanding problem with the late execution of 6763 1.1 jruoho the various deferred AML opcodes (such as Operation Regions, 6764 1.1 jruoho Buffer Fields, Buffers, and Packages). If the name string 6765 1.1 jruoho specified for the name of the new object placed the object in a 6766 1.1 jruoho scope other than the current scope, the initialization/execution 6767 1.1 jruoho of the opcode failed. The solution to this problem was to 6768 1.1 jruoho implement a mechanism where the late execution of such opcodes 6769 1.1 jruoho does not attempt to lookup/create the name a second time in an 6770 1.1 jruoho incorrect scope. This fixes the "region size computed 6771 1.1 jruoho incorrectly" problem. 6772 1.1 jruoho 6773 1.1 jruoho Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a 6774 1.1 jruoho Global Lock AE_BAD_PARAMETER error. 6775 1.1 jruoho 6776 1.1 jruoho Fixed several 64-bit issues with prototypes, casting and data 6777 1.1 jruoho types. 6778 1.1 jruoho 6779 1.1 jruoho Removed duplicate prototype from acdisasm.h 6780 1.1 jruoho 6781 1.1 jruoho Fixed an issue involving EC Operation Region Detach (Shaohua Li) 6782 1.1 jruoho 6783 1.1 jruoho Code and Data Size: Current and previous core subsystem library 6784 1.1 jruoho sizes are shown below. These are the code and data sizes for the 6785 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6786 1.1 jruoho these values do not include any ACPI driver or OSPM code.

Summary of changes for version 20030619: 6832 1.1 jruoho 6833 1.1 jruoho 1) ACPI CA Core Subsystem: 6834 1.1 jruoho 6835 1.1 jruoho Fix To/FromBCD, eliminating the need for an arch-specific #define. 6836 1.1 jruoho 6837 1.1 jruoho Do not acquire a semaphore in the S5 shutdown path. 6838 1.1 jruoho 6839 1.1 jruoho Fix ex_digits_needed for 0. (Takayoshi Kochi) 6840 1.1 jruoho 6841 1.1 jruoho Fix sleep/stall code reversal. (Andi Kleen) 6842 1.1 jruoho 6843 1.1 jruoho Revert a change having to do with control method calling 6844 1.1 jruoho semantics. 6845 1.1 jruoho 6846 1.1 jruoho 2) Linux: 6847 1.1 jruoho 6848 1.1 jruoho acpiphp update (Takayoshi Kochi) 6849 1.1 jruoho 6850 1.1 jruoho Export acpi_disabled for sonypi (Stelian Pop) 6851 1.1 jruoho 6852 1.1 jruoho Mention acpismp=force in config help 6853 1.1 jruoho 6854 1.1 jruoho Re-add acpitable.c and acpismp=force. This improves backwards 6855 1.1 jruoho 6856 1.1 jruoho compatibility and also cleans up the code to a significant degree. 6857 1.1 jruoho 6858 1.1 jruoho Add ASUS Value-add driver (Karol Kozimor and Julien Lerouge) 6859 1.1 jruoho 6860 1.1 jruoho ---------------------------------------- 6861 1.1 jruoho 22 May 2003. Summary of changes for version 20030522: 6862 1.1 jruoho 6863 1.1 jruoho 1) ACPI CA Core Subsystem: 6864 1.1 jruoho 6865 1.1 jruoho Found and fixed a reported problem where an AE_NOT_FOUND error 6866 1.1 jruoho occurred occasionally during _BST evaluation. This turned out to 6867 1.1 jruoho be an Owner ID allocation issue where a called method did not get 6868 1.1 jruoho a new ID assigned to it. Eventually, (after 64k calls), the Owner 6869 1.1 jruoho ID UINT16 would wraparound so that the ID would be the same as the 6870 1.1 jruoho caller's and the called method would delete the caller's 6871 1.1 jruoho namespace. 6872 1.1 jruoho 6873 1.1 jruoho Implemented extended error reporting for control methods that are 6874 1.1 jruoho aborted due to a run-time exception. Output includes the exact 6875 1.1 jruoho AML instruction that caused the method abort, a dump of the method 6876 1.1 jruoho locals and arguments at the time of the abort, and a trace of all 6877 1.1 jruoho nested control method calls. 6878 1.1 jruoho 6879 1.1 jruoho Modified the interpreter to allow the creation of buffers of zero 6880 1.1 jruoho length from the AML code. Implemented new code to ensure that no 6881 1.1 jruoho attempt is made to actually allocate a memory buffer (of length 6882 1.1 jruoho zero) - instead, a simple buffer object with a NULL buffer pointer 6883 1.1 jruoho and length zero is created. A warning is no longer issued when 6884 1.1 jruoho the AML attempts to create a zero-length buffer. 6885 1.1 jruoho 6886 1.1 jruoho Implemented a workaround for the "leading asterisk issue" in 6887 1.1 jruoho _HIDs, _UIDs, and _CIDs in the AML interpreter. One leading 6888 1.1 jruoho asterisk is automatically removed if present in any HID, UID, or 6889 1.1 jruoho CID strings. The iASL compiler will still flag this asterisk as 6890 1.1 jruoho an error, however. 6891 1.1 jruoho 6892 1.1 jruoho Implemented full support for _CID methods that return a package of 6893 1.1 jruoho multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() interface 6894 1.1 jruoho now additionally returns a device _CID list if present. This 6895 1.1 jruoho required a change to the external interface in order to pass an 6896 1.1 jruoho ACPI_BUFFER object as a parameter since the _CID list is of 6897 1.1 jruoho variable length. 6898 1.1 jruoho 6899 1.1 jruoho Fixed a problem with the new AE_SAME_HANDLER exception where 6900 1.1 jruoho handler initialization code did not know about this exception. 6901 1.1 jruoho 6902 1.1 jruoho Code and Data Size: Current and previous core subsystem library 6903 1.1 jruoho sizes are shown below. These are the code and data sizes for the 6904 1.1 jruoho acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6905 1.1 jruoho these values do not include any ACPI driver or OSPM code. The 6906 1.1 jruoho debug version of the code includes the debug output trace 6907 1.1 jruoho mechanism and has a much larger code and data size. Note that 6908 1.1 jruoho these values will vary depending on the efficiency of the compiler 6909 1.1 jruoho and the compiler options used during generation. 6910 1.1 jruoho 6911 1.1 jruoho Previous Release (20030509): 6912 1.1 jruoho Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total 6913 1.1 jruoho Debug Version: 156.1K Code, 63.9K Data, 220.0K Total 6914 1.1 jruoho Current Release: 6915 1.1 jruoho Non-Debug Version: 73.7K Code, 9.7K Data, 83.4K Total 6916 1.1 jruoho Debug Version: 156.9K Code, 64.2K Data, 221.1K Total 6917 1.1 jruoho 6918 1.1 jruoho 6919 1.1 jruoho 2) Linux: 6920 1.1 jruoho 6921 1.1 jruoho Fixed a bug in which we would reinitialize the ACPI interrupt 6922 1.1 jruoho after it was already working, thus disabling all ACPI and the IRQs 6923 1.1 jruoho for any other device sharing the interrupt. (Thanks to Stian 6924 1.1 jruoho Jordet) 6925 1.1 jruoho 6926 1.1 jruoho Toshiba driver update (John Belmonte) 6927 1.1 jruoho 6928 1.1 jruoho Return only 0 or 1 for our interrupt handler status (Andrew 6929 1.1 jruoho Morton) 6930 1.1 jruoho 6931 1.1 jruoho 6932 1.1 jruoho 3) iASL Compiler: 6933 1.1 jruoho 6934 1.1 jruoho Fixed a reported problem where multiple (nested) ElseIf() 6935 1.1 jruoho statements were not handled correctly by the compiler, resulting 6936 1.1 jruoho in incorrect warnings and incorrect AML code. This was a problem 6937 1.1 jruoho in both the ASL parser and the code generator. 6938 1.1 jruoho 6939 1.1 jruoho 6940 1.1 jruoho 4) Documentation: 6941 1.1 jruoho 6942 1.1 jruoho Added changes to existing interfaces, new exception codes, and new 6943 1.1 jruoho text concerning reference count object management versus garbage 6944 1.1 jruoho collection. 6945 1.1 jruoho 6946 1.1 jruoho ---------------------------------------- 6947 1.1 jruoho 09 May 2003. Summary of changes for version 20030509. 6948 1.1 jruoho 6949 1.1 jruoho 6950 1.1 jruoho 1) ACPI CA Core Subsystem: 6951 1.1 jruoho 6952 1.1 jruoho Changed the subsystem initialization sequence to hold off 6953 1.1 jruoho installation of address space handlers until the hardware has been 6954 1.1 jruoho initialized and the system has entered ACPI mode. This is because 6955 1.1 jruoho the installation of space handlers can cause _REG methods to be 6956 1.1 jruoho run. Previously, the _REG methods could potentially be run before 6957 1.1 jruoho ACPI mode was enabled. 6958 1.1 jruoho 6959 1.1 jruoho Fixed some memory leak issues related to address space handler and 6960 1.1 jruoho notify handler installation. There were some problems with the 6961 1.1 jruoho reference count mechanism caused by the fact that the handler 6962 1.1 jruoho objects are shared across several namespace objects. 6963 1.1 jruoho 6964 1.1 jruoho Fixed a reported problem where reference counts within the 6965 1.1 jruoho namespace were not properly updated when named objects created by 6966 1.1 jruoho method execution were deleted. 6967 1.1 jruoho 6968 1.1 jruoho Fixed a reported problem where multiple SSDTs caused a deletion 6969 1.1 jruoho issue during subsystem termination. Restructured the table data 6970 1.1 jruoho structures to simplify the linked lists and the related code. 6971 1.1 jruoho 6972 1.1 jruoho Fixed a problem where the table ID associated with secondary 6973 1.1 jruoho tables (SSDTs) was not being propagated into the namespace objects 6974 1.1 jruoho created by those tables. This would only present a problem for 6975 1.1 jruoho tables that are unloaded at run-time, however. 6976 1.1 jruoho 6977 1.1 jruoho Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE 6978 1.1 jruoho type as the length parameter (instead of UINT32). 6979 1.1 jruoho 6980 1.1 jruoho Solved a long-standing problem where an ALREADY_EXISTS error 6981 1.1 jruoho appears on various systems. This problem could happen when there 6982 1.1 jruoho are multiple PCI_Config operation regions under a single PCI root 6983 1.1 jruoho bus. This doesn't happen very frequently, but there are some 6984 1.1 jruoho systems that do this in the ASL. 6985 1.1 jruoho 6986 1.1 jruoho Fixed a reported problem where the internal DeleteNode function 6987 1.1 jruoho was incorrectly handling the case where a namespace node was the 6988 1.1 jruoho first in the parent's child list, and had additional peers (not 6989 1.1 jruoho the only child, but first in the list of children.) 6990 1.1 jruoho 6991 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 6992 1.1 jruoho below. These are the code and data sizes for the acpica.lib 6993 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 6994 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 6995 1.1 jruoho version of the code includes the debug output trace mechanism and 6996 1.1 jruoho has a much larger code and data size. Note that these values will 6997 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 6998 1.1 jruoho options used during generation. 6999 1.1 jruoho 7000 1.1 jruoho Previous Release 7001 1.1 jruoho Non-Debug Version: 73.7K Code, 9.5K Data, 83.2K Total 7002 1.1 jruoho Debug Version: 156.1K Code, 63.6K Data, 219.7K Total 7003 1.1 jruoho Current Release: 7004 1.1 jruoho Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total 7005 1.1 jruoho Debug Version: 156.1K Code, 63.9K Data, 220.0K Total 7006 1.1 jruoho 7007 1.1 jruoho 7008 1.1 jruoho 2) Linux: 7009 1.1 jruoho 7010 1.1 jruoho Allow ":" in OS override string (Ducrot Bruno) 7011 1.1 jruoho 7012 1.1 jruoho Kobject fix (Greg KH) 7013 1.1 jruoho 7014 1.1 jruoho 7015 1.1 jruoho 3 iASL Compiler/Disassembler: 7016 1.1 jruoho 7017 1.1 jruoho Fixed a problem in the generation of the C source code files (AML 7018 1.1 jruoho is emitted in C source statements for BIOS inclusion) where the 7019 1.1 jruoho Ascii dump that appears within a C comment at the end of each line 7020 1.1 jruoho could cause a compile time error if the AML sequence happens to 7021 1.1 jruoho have an open comment or close comment sequence embedded. 7022 1.1 jruoho 7023 1.1 jruoho 7024 1.1 jruoho ---------------------------------------- 7025 1.1 jruoho 24 April 2003. Summary of changes for version 20030424. 7026 1.1 jruoho 7027 1.1 jruoho 7028 1.1 jruoho 1) ACPI CA Core Subsystem: 7029 1.1 jruoho 7030 1.1 jruoho Support for big-endian systems has been implemented. Most of the 7031 1.1 jruoho support has been invisibly added behind big-endian versions of the 7032 1.1 jruoho ACPI_MOVE_* macros. 7033 1.1 jruoho 7034 1.1 jruoho Fixed a problem in AcpiHwDisableGpeBlock() and 7035 1.1 jruoho AcpiHwClearGpeBlock() where an incorrect offset was passed to the 7036 1.1 jruoho low level hardware write routine. The offset parameter was 7037 1.1 jruoho actually eliminated from the low level read/write routines because 7038 1.1 jruoho they had become obsolete. 7039 1.1 jruoho 7040 1.1 jruoho Fixed a problem where a handler object was deleted twice during 7041 1.1 jruoho the removal of a fixed event handler. 7042 1.1 jruoho 7043 1.1 jruoho 7044 1.1 jruoho 2) Linux: 7045 1.1 jruoho 7046 1.1 jruoho A fix for SMP systems with link devices was contributed by 7047 1.1 jruoho 7048 1.1 jruoho Compaq's Dan Zink. 7049 1.1 jruoho 7050 1.1 jruoho (2.5) Return whether we handled the interrupt in our IRQ handler. 7051 1.1 jruoho (Linux ISRs no longer return void, so we can propagate the handler 7052 1.1 jruoho return value from the ACPI CA core back to the OS.) 7053 1.1 jruoho 7054 1.1 jruoho 7055 1.1 jruoho 7056 1.1 jruoho 3) Documentation: 7057 1.1 jruoho 7058 1.1 jruoho The ACPI CA Programmer Reference has been updated to reflect new 7059 1.1 jruoho interfaces and changes to existing interfaces. 7060 1.1 jruoho 7061 1.1 jruoho ---------------------------------------- 7062 1.1 jruoho 28 March 2003. Summary of changes for version 20030328. 7063 1.1 jruoho 7064 1.1 jruoho 1) ACPI CA Core Subsystem: 7065 1.1 jruoho 7066 1.1 jruoho The GPE Block Device support has been completed. New interfaces 7067 1.1 jruoho are AcpiInstallGpeBlock and AcpiRemoveGpeBlock. The Event 7068 1.1 jruoho interfaces (enable, disable, clear, getstatus) have been split 7069 1.1 jruoho into separate interfaces for Fixed Events and General Purpose 7070 1.1 jruoho Events (GPEs) in order to support GPE Block Devices properly. 7071 1.1 jruoho 7072 1.1 jruoho Fixed a problem where the error message "Failed to acquire 7073 1.1 jruoho semaphore" would appear during operations on the embedded 7074 1.1 jruoho controller (EC). 7075 1.1 jruoho 7076 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7077 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7078 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7079 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7080 1.1 jruoho version of the code includes the debug output trace mechanism and 7081 1.1 jruoho has a much larger code and data size.

Summary of changes for version 20030228. 7095 1.1 jruoho 7096 1.1 jruoho 7097 1.1 jruoho 1) ACPI CA Core Subsystem: 7098 1.1 jruoho 7099 1.1 jruoho The GPE handling and dispatch code has been completely overhauled 7100 1.1 jruoho in preparation for support of GPE Block Devices (ID ACPI0006). 7101 1.1 jruoho This affects internal data structures and code only; there should 7102 1.1 jruoho be no differences visible externally. One new file has been 7103 1.1 jruoho added, evgpeblk.c 7104 1.1 jruoho 7105 1.1 jruoho The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only 7106 1.1 jruoho fields that are used to determine the GPE block lengths. The 7107 1.1 jruoho REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address 7108 1.1 jruoho structures are ignored. This is per the ACPI specification but it 7109 1.1 jruoho isn't very clear. The full 256 Block 0/1 GPEs are now supported 7110 1.1 jruoho (the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128). 7111 1.1 jruoho 7112 1.1 jruoho In the SCI interrupt handler, removed the read of the PM1_CONTROL 7113 1.1 jruoho register to look at the SCI_EN bit. On some machines, this read 7114 1.1 jruoho causes an SMI event and greatly slows down SCI events. (This may 7115 1.1 jruoho in fact be the cause of slow battery status response on some 7116 1.1 jruoho systems.) 7117 1.1 jruoho 7118 1.1 jruoho Fixed a problem where a store of a NULL string to a package object 7119 1.1 jruoho could cause the premature deletion of the object. This was seen 7120 1.1 jruoho during execution of the battery _BIF method on some systems, 7121 1.1 jruoho resulting in no battery data being returned. 7122 1.1 jruoho 7123 1.1 jruoho Added AcpiWalkResources interface to simplify parsing of resource 7124 1.1 jruoho lists. 7125 1.1 jruoho 7126 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7127 1.1 jruoho below.

This is 7162 1.1 jruoho causing us to think that some systems support C2 when they really 7163 1.1 jruoho don't. 7164 1.1 jruoho 7165 1.1 jruoho Do not count processor objects for non-present CPUs (Thanks to 7166 1.1 jruoho Dominik Brodowski) 7167 1.1 jruoho 7168 1.1 jruoho 7169 1.1 jruoho 3) iASL Compiler: 7170 1.1 jruoho 7171 1.1 jruoho Fixed a problem where ASL include files could not be found and 7172 1.1 jruoho opened. 7173 1.1 jruoho 7174 1.1 jruoho Added support for the _PDC reserved name. 7175 1.1 jruoho 7176 1.1 jruoho 7177 1.1 jruoho ---------------------------------------- 7178 1.1 jruoho 22 January 2003. Summary of changes for version 20030122. 7179 1.1 jruoho 7180 1.1 jruoho 7181 1.1 jruoho 1) ACPI CA Core Subsystem: 7182 1.1 jruoho 7183 1.1 jruoho Added a check for constructs of the form: Store (Local0, Local0) 7184 1.1 jruoho where Local0 is not initialized. Apparently, some BIOS 7185 1.1 jruoho programmers believe that this is a NOOP. Since this store doesn't 7186 1.1 jruoho do anything anyway, the new prototype behavior will ignore this 7187 1.1 jruoho error. This is a case where we can relax the strict checking in 7188 1.1 jruoho the interpreter in the name of compatibility. 7189 1.1 jruoho 7190 1.1 jruoho 7191 1.1 jruoho 2) Linux 7192 1.1 jruoho 7193 1.1 jruoho The AcpiSrc Source Conversion Utility has been released with the 7194 1.1 jruoho Linux package for the first time. This is the utility that is 7195 1.1 jruoho used to convert the ACPI CA base source code to the Linux version. 7196 1.1 jruoho 7197 1.1 jruoho (Both) Handle P_BLK lengths shorter than 6 more gracefully 7198 1.1 jruoho 7199 1.1 jruoho (Both) Move more headers to include/acpi, and delete an unused 7200 1.1 jruoho header. 7201 1.1 jruoho 7202 1.1 jruoho (Both) Move drivers/acpi/include directory to include/acpi 7203 1.1 jruoho 7204 1.1 jruoho (Both) Boot functions don't use cmdline, so don't pass it around 7205 1.1 jruoho 7206 1.1 jruoho (Both) Remove include of unused header (Adrian Bunk) 7207 1.1 jruoho 7208 1.1 jruoho (Both) acpiphp.h includes both linux/acpi.h and acpi_bus.h. Since 7209 1.1 jruoho the 7210 1.1 jruoho former now also includes the latter, acpiphp.h only needs the one, 7211 1.1 jruoho now. 7212 1.1 jruoho 7213 1.1 jruoho (2.5) Make it possible to select method of bios restoring after S3 7214 1.1 jruoho resume.

Summary of changes for version 20030109. 7239 1.1 jruoho 7240 1.1 jruoho 1) ACPI CA Core Subsystem: 7241 1.1 jruoho 7242 1.1 jruoho Changed the behavior of the internal Buffer-to-String conversion 7243 1.1 jruoho function. The current ACPI specification states that the contents 7244 1.1 jruoho of the buffer are "converted to a string of two-character 7245 1.1 jruoho hexadecimal numbers, each separated by a space". Unfortunately, 7246 1.1 jruoho this definition is not backwards compatible with existing ACPI 1.0 7247 1.1 jruoho implementations (although the behavior was not defined in the ACPI 7248 1.1 jruoho 1.0 specification). The new behavior simply copies data from the 7249 1.1 jruoho buffer to the string until a null character is found or the end of 7250 1.1 jruoho the buffer is reached. The new String object is always null 7251 1.1 jruoho terminated. This problem was seen during the generation of _BIF 7252 1.1 jruoho battery data where incorrect strings were returned for battery 7253 1.1 jruoho type, etc. This will also require an errata to the ACPI 7254 1.1 jruoho specification. 7255 1.1 jruoho 7256 1.1 jruoho Renamed all instances of NATIVE_UINT and NATIVE_INT to 7257 1.1 jruoho ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively. 7258 1.1 jruoho 7259 1.1 jruoho Copyright in all module headers (both Linux and non-Linux) has be 7260 1.1 jruoho updated to 2003. 7261 1.1 jruoho 7262 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7263 1.1 jruoho below.

Summary of changes for version 20021212. 7322 1.1 jruoho 7323 1.1 jruoho 7324 1.1 jruoho 1) ACPI CA Core Subsystem: 7325 1.1 jruoho 7326 1.1 jruoho Fixed a problem where the creation of a zero-length AML Buffer 7327 1.1 jruoho would cause a fault. 7328 1.1 jruoho 7329 1.1 jruoho Fixed a problem where a Buffer object that pointed to a static AML 7330 1.1 jruoho buffer (in an ACPI table) could inadvertently be deleted, causing 7331 1.1 jruoho memory corruption. 7332 1.1 jruoho 7333 1.1 jruoho Fixed a problem where a user buffer (passed in to the external 7334 1.1 jruoho ACPI CA interfaces) could be overwritten if the buffer was too 7335 1.1 jruoho small to complete the operation, causing memory corruption. 7336 1.1 jruoho 7337 1.1 jruoho Fixed a problem in the Buffer-to-String conversion code where a 7338 1.1 jruoho string of length one was always returned, regardless of the size 7339 1.1 jruoho of the input Buffer object. 7340 1.1 jruoho 7341 1.1 jruoho Removed the NATIVE_CHAR data type across the entire source due to 7342 1.1 jruoho lack of need and lack of consistent use. 7343 1.1 jruoho 7344 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7345 1.1 jruoho below.

Summary of changes for version 20021205. 7363 1.1 jruoho 7364 1.1 jruoho 1) ACPI CA Core Subsystem: 7365 1.1 jruoho 7366 1.1 jruoho Fixed a problem where a store to a String or Buffer object could 7367 1.1 jruoho cause corruption of the DSDT if the object type being stored was 7368 1.1 jruoho the same as the target object type and the length of the object 7369 1.1 jruoho being stored was equal to or smaller than the original (existing) 7370 1.1 jruoho target object. This was seen to cause corruption of battery _BIF 7371 1.1 jruoho buffers if the _BIF method modified the buffer on the fly. 7372 1.1 jruoho 7373 1.1 jruoho Fixed a problem where an internal error was generated if a control 7374 1.1 jruoho method invocation was used in an OperationRegion, Buffer, or 7375 1.1 jruoho Package declaration. This was caused by the deferred parsing of 7376 1.1 jruoho the control method and thus the deferred creation of the internal 7377 1.1 jruoho method object. The solution to this problem was to create the 7378 1.1 jruoho internal method object at the moment the method is encountered in 7379 1.1 jruoho the first pass - so that subsequent references to the method will 7380 1.1 jruoho able to obtain the required parameter count and thus properly 7381 1.1 jruoho parse the method invocation. This problem presented itself as an 7382 1.1 jruoho AE_AML_INTERNAL during the pass 1 parse phase during table load. 7383 1.1 jruoho 7384 1.1 jruoho Fixed a problem where the internal String object copy routine did 7385 1.1 jruoho not always allocate sufficient memory for the target String object 7386 1.1 jruoho and caused memory corruption. This problem was seen to cause 7387 1.1 jruoho "Allocation already present in list!" errors as memory allocation 7388 1.1 jruoho became corrupted. 7389 1.1 jruoho 7390 1.1 jruoho Implemented a new function for the evaluation of namespace objects 7391 1.1 jruoho that allows the specification of the allowable return object 7392 1.1 jruoho types. This simplifies a lot of code that checks for a return 7393 1.1 jruoho object of one or more specific objects returned from the 7394 1.1 jruoho evaluation (such as _STA, etc.) This may become and external 7395 1.1 jruoho function if it would be useful to ACPI-related drivers. 7396 1.1 jruoho 7397 1.1 jruoho Completed another round of prefixing #defines with "ACPI_" for 7398 1.1 jruoho clarity. 7399 1.1 jruoho 7400 1.1 jruoho Completed additional code restructuring to allow more modular 7401 1.1 jruoho linking for iASL compiler and AcpiExec. Several files were split 7402 1.1 jruoho creating new files. New files: nsparse.c dsinit.c evgpe.c 7403 1.1 jruoho 7404 1.1 jruoho Implemented an abort mechanism to terminate an executing control 7405 1.1 jruoho method via the AML debugger. This feature is useful for debugging 7406 1.1 jruoho control methods that depend (wait) for specific hardware 7407 1.1 jruoho responses. 7408 1.1 jruoho 7409 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7410 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7411 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7412 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7413 1.1 jruoho version of the code includes the debug output trace mechanism and 7414 1.1 jruoho has a much larger code and data size.

If specified in the ASL, the optional "Resource 7430 1.1 jruoho Source Index" and "Resource Source" fields were not inserted into 7431 1.1 jruoho the correct location within the AML resource descriptor, creating 7432 1.1 jruoho an invalid descriptor. 7433 1.1 jruoho 7434 1.1 jruoho Fixed a disassembler problem for "Interrupt" resource descriptors. 7435 1.1 jruoho The optional "Resource Source Index" and "Resource Source" fields 7436 1.1 jruoho were ignored. 7437 1.1 jruoho 7438 1.1 jruoho 7439 1.1 jruoho ---------------------------------------- 7440 1.1 jruoho 22 November 2002. Summary of changes for version 20021122. 7441 1.1 jruoho 7442 1.1 jruoho 7443 1.1 jruoho 1) ACPI CA Core Subsystem: 7444 1.1 jruoho 7445 1.1 jruoho Fixed a reported problem where an object stored to a Method Local 7446 1.1 jruoho or Arg was not copied to a new object during the store - the 7447 1.1 jruoho object pointer was simply copied to the Local/Arg. This caused 7448 1.1 jruoho all subsequent operations on the Local/Arg to also affect the 7449 1.1 jruoho original source of the store operation. 7450 1.1 jruoho 7451 1.1 jruoho Fixed a problem where a store operation to a Method Local or Arg 7452 1.1 jruoho was not completed properly if the Local/Arg contained a reference 7453 1.1 jruoho (from RefOf) to a named field. The general-purpose store-to- 7454 1.1 jruoho namespace-node code is now used so that this case is handled 7455 1.1 jruoho automatically. 7456 1.1 jruoho 7457 1.1 jruoho Fixed a problem where the internal object copy routine would cause 7458 1.1 jruoho a protection fault if the object being copied was a Package and 7459 1.1 jruoho contained either 1) a NULL package element or 2) a nested sub- 7460 1.1 jruoho package. 7461 1.1 jruoho 7462 1.1 jruoho Fixed a problem with the GPE initialization that resulted from an 7463 1.1 jruoho ambiguity in the ACPI specification. One section of the 7464 1.1 jruoho specification states that both the address and length of the GPE 7465 1.1 jruoho block must be zero if the block is not supported. Another section 7466 1.1 jruoho implies that only the address need be zero if the block is not 7467 1.1 jruoho supported. The code has been changed so that both the address and 7468 1.1 jruoho the length must be non-zero to indicate a valid GPE block (i.e., 7469 1.1 jruoho if either the address or the length is zero, the GPE block is 7470 1.1 jruoho invalid.) 7471 1.1 jruoho 7472 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7473 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7474 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7475 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7476 1.1 jruoho version of the code includes the debug output trace mechanism and 7477 1.1 jruoho has a much larger code and data size. Note that these values will 7478 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 7479 1.1 jruoho options used during generation. 7480 1.1 jruoho 7481 1.1 jruoho Previous Release 7482 1.1 jruoho Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total 7483 1.1 jruoho Debug Version: 152.7K Code, 63.2K Data, 215.5K Total 7484 1.1 jruoho Current Release: 7485 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 7486 1.1 jruoho Debug Version: 152.9K Code, 63.3K Data, 216.2K Total 7487 1.1 jruoho 7488 1.1 jruoho 7489 1.1 jruoho 2) Linux 7490 1.1 jruoho 7491 1.1 jruoho Cleaned up EC driver. Exported an external EC read/write 7492 1.1 jruoho interface. By going through this, other drivers (most notably 7493 1.1 jruoho sonypi) will be able to serialize access to the EC. 7494 1.1 jruoho 7495 1.1 jruoho 7496 1.1 jruoho 3) iASL Compiler/Disassembler 7497 1.1 jruoho 7498 1.1 jruoho Implemented support to optionally generate include files for both 7499 1.1 jruoho ASM and C (the -i switch). This simplifies BIOS development by 7500 1.1 jruoho automatically creating include files that contain external 7501 1.1 jruoho declarations for the symbols that are created within the 7502 1.1 jruoho 7503 1.1 jruoho (optionally generated) ASM and C AML source files. 7504 1.1 jruoho 7505 1.1 jruoho 7506 1.1 jruoho ---------------------------------------- 7507 1.1 jruoho 15 November 2002. Summary of changes for version 20021115. 7508 1.1 jruoho 7509 1.1 jruoho 1) ACPI CA Core Subsystem: 7510 1.1 jruoho 7511 1.1 jruoho Fixed a memory leak problem where an error during resolution of 7512 1.1 jruoho 7513 1.1 jruoho method arguments during a method invocation from another method 7514 1.1 jruoho failed to cleanup properly by deleting all successfully resolved 7515 1.1 jruoho argument objects. 7516 1.1 jruoho 7517 1.1 jruoho Fixed a problem where the target of the Index() operator was not 7518 1.1 jruoho correctly constructed if the source object was a package. This 7519 1.1 jruoho problem has not been detected because the use of a target operand 7520 1.1 jruoho with Index() is very rare. 7521 1.1 jruoho 7522 1.1 jruoho Fixed a problem with the Index() operator where an attempt was 7523 1.1 jruoho made to delete the operand objects twice. 7524 1.1 jruoho 7525 1.1 jruoho Fixed a problem where an attempt was made to delete an operand 7526 1.1 jruoho twice during execution of the CondRefOf() operator if the target 7527 1.1 jruoho did not exist. 7528 1.1 jruoho 7529 1.1 jruoho Implemented the first of perhaps several internal create object 7530 1.1 jruoho functions that create and initialize a specific object type. This 7531 1.1 jruoho consolidates duplicated code wherever the object is created, thus 7532 1.1 jruoho shrinking the size of the subsystem. 7533 1.1 jruoho 7534 1.1 jruoho Implemented improved debug/error messages for errors that occur 7535 1.1 jruoho during nested method invocations. All executing method pathnames 7536 1.1 jruoho are displayed (with the error) as the call stack is unwound - thus 7537 1.1 jruoho simplifying debug. 7538 1.1 jruoho 7539 1.1 jruoho Fixed a problem introduced in the 10/02 release that caused 7540 1.1 jruoho premature deletion of a buffer object if a buffer was used as an 7541 1.1 jruoho ASL operand where an integer operand is required (Thus causing an 7542 1.1 jruoho implicit object conversion from Buffer to Integer.) The change in 7543 1.1 jruoho the 10/02 release was attempting to fix a memory leak (albeit 7544 1.1 jruoho incorrectly.) 7545 1.1 jruoho 7546 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7547 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7548 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7549 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7550 1.1 jruoho version of the code includes the debug output trace mechanism and 7551 1.1 jruoho has a much larger code and data size. Note that these values will 7552 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 7553 1.1 jruoho options used during generation. 7554 1.1 jruoho 7555 1.1 jruoho Previous Release 7556 1.1 jruoho Non-Debug Version: 71.9K Code, 9.1K Data, 81.0K Total 7557 1.1 jruoho Debug Version: 153.1K Code, 63.3K Data, 216.4K Total 7558 1.1 jruoho Current Release: 7559 1.1 jruoho Non-Debug Version: 71.3K Code, 9.0K Data, 80.3K Total 7560 1.1 jruoho Debug Version: 152.7K Code, 63.2K Data, 215.5K Total 7561 1.1 jruoho 7562 1.1 jruoho 7563 1.1 jruoho 2) Linux 7564 1.1 jruoho 7565 1.1 jruoho Changed the implementation of the ACPI semaphores to use down() 7566 1.1 jruoho instead of down_interruptable(). It is important that the 7567 1.1 jruoho execution of ACPI control methods not be interrupted by signals. 7568 1.1 jruoho Methods must run to completion, or the system may be left in an 7569 1.1 jruoho unknown/unstable state. 7570 1.1 jruoho 7571 1.1 jruoho Fixed a compilation error when CONFIG_SOFTWARE_SUSPEND is not set. 7572 1.1 jruoho (Shawn Starr) 7573 1.1 jruoho 7574 1.1 jruoho 7575 1.1 jruoho 3) iASL Compiler/Disassembler 7576 1.1 jruoho 7577 1.1 jruoho 7578 1.1 jruoho Changed the default location of output files. All output files 7579 1.1 jruoho are now placed in the current directory by default instead of in 7580 1.1 jruoho the directory of the source file. This change may affect some 7581 1.1 jruoho existing makefiles, but it brings the behavior of the compiler in 7582 1.1 jruoho line with other similar tools. The location of the output files 7583 1.1 jruoho can be overridden with the -p command line switch. 7584 1.1 jruoho 7585 1.1 jruoho 7586 1.1 jruoho ---------------------------------------- 7587 1.1 jruoho 11 November 2002. Summary of changes for version 20021111. 7588 1.1 jruoho 7589 1.1 jruoho 7590 1.1 jruoho 0) ACPI Specification 2.0B is released and is now available at: 7591 1.1 jruoho http://www.acpi.info/index.html 7592 1.1 jruoho 7593 1.1 jruoho 7594 1.1 jruoho 1) ACPI CA Core Subsystem: 7595 1.1 jruoho 7596 1.1 jruoho Implemented support for the ACPI 2.0 SMBus Operation Regions. 7597 1.1 jruoho This includes the early detection and handoff of the request to 7598 1.1 jruoho the SMBus region handler (avoiding all of the complex field 7599 1.1 jruoho support code), and support for the bidirectional return packet 7600 1.1 jruoho from an SMBus write operation. This paves the way for the 7601 1.1 jruoho development of SMBus drivers in each host operating system. 7602 1.1 jruoho 7603 1.1 jruoho Fixed a problem where the semaphore WAIT_FOREVER constant was 7604 1.1 jruoho defined as 32 bits, but must be 16 bits according to the ACPI 7605 1.1 jruoho specification. This had the side effect of causing ASL 7606 1.1 jruoho Mutex/Event timeouts even though the ASL code requested a wait 7607 1.1 jruoho forever. Changed all internal references to the ACPI timeout 7608 1.1 jruoho parameter to 16 bits to prevent future problems. Changed the name 7609 1.1 jruoho of WAIT_FOREVER to ACPI_WAIT_FOREVER. 7610 1.1 jruoho 7611 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7612 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7613 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7614 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7615 1.1 jruoho version of the code includes the debug output trace mechanism and 7616 1.1 jruoho has a much larger code and data size. Note that these values will 7617 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 7618 1.1 jruoho options used during generation. 7619 1.1 jruoho 7620 1.1 jruoho Previous Release 7621 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 7622 1.1 jruoho Debug Version: 152.3K Code, 63.0K Data, 215.3K Total 7623 1.1 jruoho Current Release: 7624 1.1 jruoho Non-Debug Version: 71.9K Code, 9.1K Data, 81.0K Total 7625 1.1 jruoho Debug Version: 153.1K Code, 63.3K Data, 216.4K Total 7626 1.1 jruoho 7627 1.1 jruoho 7628 1.1 jruoho 2) Linux 7629 1.1 jruoho 7630 1.1 jruoho Module loading/unloading fixes (John Cagle) 7631 1.1 jruoho 7632 1.1 jruoho 7633 1.1 jruoho 3) iASL Compiler/Disassembler 7634 1.1 jruoho 7635 1.1 jruoho Added support for the SMBBlockProcessCall keyword (ACPI 2.0) 7636 1.1 jruoho 7637 1.1 jruoho Implemented support for the disassembly of all SMBus protocol 7638 1.1 jruoho keywords (SMBQuick, SMBWord, etc.) 7639 1.1 jruoho 7640 1.1 jruoho ---------------------------------------- 7641 1.1 jruoho 01 November 2002. Summary of changes for version 20021101. 7642 1.1 jruoho 7643 1.1 jruoho 7644 1.1 jruoho 1) ACPI CA Core Subsystem: 7645 1.1 jruoho 7646 1.1 jruoho Fixed a problem where platforms that have a GPE1 block but no GPE0 7647 1.1 jruoho block were not handled correctly. This resulted in a "GPE 7648 1.1 jruoho overlap" error message. GPE0 is no longer required. 7649 1.1 jruoho 7650 1.1 jruoho Removed code added in the previous release that inserted nodes 7651 1.1 jruoho into the namespace in alphabetical order. This caused some side- 7652 1.1 jruoho effects on various machines. The root cause of the problem is 7653 1.1 jruoho still under investigation since in theory, the internal ordering 7654 1.1 jruoho of the namespace nodes should not matter. 7655 1.1 jruoho 7656 1.1 jruoho 7657 1.1 jruoho Enhanced error reporting for the case where a named object is not 7658 1.1 jruoho found during control method execution. The full ACPI namepath 7659 1.1 jruoho (name reference) of the object that was not found is displayed in 7660 1.1 jruoho this case. 7661 1.1 jruoho 7662 1.1 jruoho Note: as a result of the overhaul of the namespace object types in 7663 1.1 jruoho the previous release, the namespace nodes for the predefined 7664 1.1 jruoho scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE 7665 1.1 jruoho instead of ACPI_TYPE_ANY. This simplifies the namespace 7666 1.1 jruoho management code but may affect code that walks the namespace tree 7667 1.1 jruoho looking for specific object types. 7668 1.1 jruoho 7669 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7670 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7671 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7672 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7673 1.1 jruoho version of the code includes the debug output trace mechanism and 7674 1.1 jruoho has a much larger code and data size. Note that these values will 7675 1.1 jruoho vary depending on the efficiency of the compiler and the compiler 7676 1.1 jruoho options used during generation. 7677 1.1 jruoho 7678 1.1 jruoho Previous Release 7679 1.1 jruoho Non-Debug Version: 70.7K Code, 8.6K Data, 79.3K Total 7680 1.1 jruoho Debug Version: 151.7K Code, 62.4K Data, 214.1K Total 7681 1.1 jruoho Current Release: 7682 1.1 jruoho Non-Debug Version: 71.4K Code, 9.0K Data, 80.4K Total 7683 1.1 jruoho Debug Version: 152.3K Code, 63.0K Data, 215.3K Total 7684 1.1 jruoho 7685 1.1 jruoho 7686 1.1 jruoho 2) Linux 7687 1.1 jruoho 7688 1.1 jruoho Fixed a problem introduced in the previous release where the 7689 1.1 jruoho Processor and Thermal objects were not recognized and installed in 7690 1.1 jruoho /proc. This was related to the scope type change described above. 7691 1.1 jruoho 7692 1.1 jruoho 7693 1.1 jruoho 3) iASL Compiler/Disassembler 7694 1.1 jruoho 7695 1.1 jruoho Implemented the -g option to get all of the required ACPI tables 7696 1.1 jruoho from the registry and save them to files (Windows version of the 7697 1.1 jruoho compiler only.) The required tables are the FADT, FACS, and DSDT. 7698 1.1 jruoho 7699 1.1 jruoho Added ACPI table checksum validation during table disassembly in 7700 1.1 jruoho order to catch corrupted tables. 7701 1.1 jruoho 7702 1.1 jruoho 7703 1.1 jruoho ---------------------------------------- 7704 1.1 jruoho 22 October 2002. Summary of changes for version 20021022. 7705 1.1 jruoho 7706 1.1 jruoho 1) ACPI CA Core Subsystem: 7707 1.1 jruoho 7708 1.1 jruoho Implemented a restriction on the Scope operator that the target 7709 1.1 jruoho must already exist in the namespace at the time the operator is 7710 1.1 jruoho encountered (during table load or method execution). In other 7711 1.1 jruoho words, forward references are not allowed and Scope() cannot 7712 1.1 jruoho create a new object. This changes the previous behavior where the 7713 1.1 jruoho interpreter would create the name if not found. This new behavior 7714 1.1 jruoho correctly enables the search-to-root algorithm during namespace 7715 1.1 jruoho lookup of the target name. Because of this upsearch, this fixes 7716 1.1 jruoho the known Compaq _SB_.OKEC problem and makes both the AML 7717 1.1 jruoho interpreter and iASL compiler compatible with other ACPI 7718 1.1 jruoho implementations. 7719 1.1 jruoho 7720 1.1 jruoho Completed a major overhaul of the internal ACPI object types for 7721 1.1 jruoho the ACPI Namespace and the associated operand objects. Many of 7722 1.1 jruoho these types had become obsolete with the introduction of the two- 7723 1.1 jruoho pass namespace load. This cleanup simplifies the code and makes 7724 1.1 jruoho the entire namespace load mechanism much clearer and easier to 7725 1.1 jruoho understand. 7726 1.1 jruoho 7727 1.1 jruoho Improved debug output for tracking scope opening/closing to help 7728 1.1 jruoho diagnose scoping issues. The old scope name as well as the new 7729 1.1 jruoho scope name are displayed. Also improved error messages for 7730 1.1 jruoho problems with ASL Mutex objects and error messages for GPE 7731 1.1 jruoho problems. 7732 1.1 jruoho 7733 1.1 jruoho Cleaned up the namespace dump code, removed obsolete code. 7734 1.1 jruoho 7735 1.1 jruoho All string output (for all namespace/object dumps) now uses the 7736 1.1 jruoho common ACPI string output procedure which handles escapes properly 7737 1.1 jruoho and does not emit non-printable characters. 7738 1.1 jruoho 7739 1.1 jruoho Fixed some issues with constants in the 64-bit version of the 7740 1.1 jruoho local C library (utclib.c) 7741 1.1 jruoho 7742 1.1 jruoho 7743 1.1 jruoho 2) Linux 7744 1.1 jruoho 7745 1.1 jruoho EC Driver: No longer attempts to acquire the Global Lock at 7746 1.1 jruoho interrupt level. 7747 1.1 jruoho 7748 1.1 jruoho 7749 1.1 jruoho 3) iASL Compiler/Disassembler 7750 1.1 jruoho 7751 1.1 jruoho Implemented ACPI 2.0B grammar change that disallows all Type 1 and 7752 1.1 jruoho 2 opcodes outside of a control method. This means that the 7753 1.1 jruoho "executable" operators (versus the "namespace" operators) cannot 7754 1.1 jruoho be used at the table level; they can only be used within a control 7755 1.1 jruoho method. 7756 1.1 jruoho 7757 1.1 jruoho Implemented the restriction on the Scope() operator where the 7758 1.1 jruoho target must already exist in the namespace at the time the 7759 1.1 jruoho operator is encountered (during ASL compilation). In other words, 7760 1.1 jruoho forward references are not allowed and Scope() cannot create a new 7761 1.1 jruoho object. This makes the iASL compiler compatible with other ACPI 7762 1.1 jruoho implementations and makes the Scope() implementation adhere to the 7763 1.1 jruoho ACPI specification. 7764 1.1 jruoho 7765 1.1 jruoho Fixed a problem where namepath optimization for the Alias operator 7766 1.1 jruoho was optimizing the wrong path (of the two namepaths.) This caused 7767 1.1 jruoho a "Missing alias link" error message. 7768 1.1 jruoho 7769 1.1 jruoho Fixed a problem where an "unknown reserved name" warning could be 7770 1.1 jruoho incorrectly generated for names like "_SB" when the trailing 7771 1.1 jruoho underscore is not used in the original ASL. 7772 1.1 jruoho 7773 1.1 jruoho Fixed a problem where the reserved name check did not handle 7774 1.1 jruoho NamePaths with multiple NameSegs correctly. The first nameseg of 7775 1.1 jruoho the NamePath was examined instead of the last NameSeg. 7776 1.1 jruoho 7777 1.1 jruoho 7778 1.1 jruoho ---------------------------------------- 7779 1.1 jruoho 7780 1.1 jruoho 02 October 2002. Summary of changes for this release. 7781 1.1 jruoho 7782 1.1 jruoho 7783 1.1 jruoho 1) ACPI CA Core Subsystem version 20021002: 7784 1.1 jruoho 7785 1.1 jruoho Fixed a problem where a store/copy of a string to an existing 7786 1.1 jruoho string did not always set the string length properly in the String 7787 1.1 jruoho object. 7788 1.1 jruoho 7789 1.1 jruoho Fixed a reported problem with the ToString operator where the 7790 1.1 jruoho behavior was identical to the ToHexString operator instead of just 7791 1.1 jruoho simply converting a raw buffer to a string data type. 7792 1.1 jruoho 7793 1.1 jruoho Fixed a problem where CopyObject and the other "explicit" 7794 1.1 jruoho conversion operators were not updating the internal namespace node 7795 1.1 jruoho type as part of the store operation. 7796 1.1 jruoho 7797 1.1 jruoho Fixed a memory leak during implicit source operand conversion 7798 1.1 jruoho where the original object was not deleted if it was converted to a 7799 1.1 jruoho new object of a different type. 7800 1.1 jruoho 7801 1.1 jruoho Enhanced error messages for all problems associated with namespace 7802 1.1 jruoho lookups. Common procedure generates and prints the lookup name as 7803 1.1 jruoho well as the formatted status. 7804 1.1 jruoho 7805 1.1 jruoho Completed implementation of a new design for the Alias support 7806 1.1 jruoho within the namespace. The existing design did not handle the case 7807 1.1 jruoho where a new object was assigned to one of the two names due to the 7808 1.1 jruoho use of an explicit conversion operator, resulting in the two names 7809 1.1 jruoho pointing to two different objects. The new design simply points 7810 1.1 jruoho the Alias name to the original name node - not to the object. 7811 1.1 jruoho This results in a level of indirection that must be handled in the 7812 1.1 jruoho name resolution mechanism. 7813 1.1 jruoho 7814 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 7815 1.1 jruoho below. These are the code and data sizes for the acpica.lib 7816 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 7817 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 7818 1.1 jruoho version of the code includes the debug output trace mechanism and 7819 1.1 jruoho has a larger code and data size. Note that these values will vary 7820 1.1 jruoho depending on the efficiency of the compiler and the compiler 7821 1.1 jruoho options used during generation. 7822 1.1 jruoho 7823 1.1 jruoho Previous Release 7824 1.1 jruoho Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total 7825 1.1 jruoho Debug Version: 150.0K Code, 61.7K Data, 211.7K Total 7826 1.1 jruoho Current Release: 7827 1.1 jruoho Non-Debug Version: 70.7K Code, 8.6K Data, 79.3K Total 7828 1.1 jruoho Debug Version: 151.7K Code, 62.4K Data, 214.1K Total 7829 1.1 jruoho 7830 1.1 jruoho 7831 1.1 jruoho 2) Linux 7832 1.1 jruoho 7833 1.1 jruoho Initialize thermal driver's timer before it is used.

(David Mosberger) 7843 1.1 jruoho 7844 1.1 jruoho Fix reversed logic in blacklist code. (Sergio Monteiro Basto) 7845 1.1 jruoho 7846 1.1 jruoho Replace ACPI_DEBUG define with ACPI_DEBUG_OUTPUT. (Dominik 7847 1.1 jruoho Brodowski) 7848 1.1 jruoho 7849 1.1 jruoho 7850 1.1 jruoho 3) iASL Compiler/Disassembler 7851 1.1 jruoho 7852 1.1 jruoho Clarified some warning/error messages. 7853 1.1 jruoho 7854 1.1 jruoho 7855 1.1 jruoho ---------------------------------------- 7856 1.1 jruoho 18 September 2002. Summary of changes for this release. 7857 1.1 jruoho 7858 1.1 jruoho 7859 1.1 jruoho 1) ACPI CA Core Subsystem version 20020918: 7860 1.1 jruoho 7861 1.1 jruoho Fixed a reported problem with reference chaining (via the Index() 7862 1.1 jruoho and RefOf() operators) in the ObjectType() and SizeOf() operators. 7863 1.1 jruoho The definition of these operators includes the dereferencing of 7864 1.1 jruoho all chained references to return information on the base object. 7865 1.1 jruoho 7866 1.1 jruoho Fixed a problem with stores to indexed package elements - the 7867 1.1 jruoho existing code would not complete the store if an "implicit 7868 1.1 jruoho conversion" was not performed. In other words, if the existing 7869 1.1 jruoho object (package element) was to be replaced completely, the code 7870 1.1 jruoho didn't handle this case. 7871 1.1 jruoho 7872 1.1 jruoho Relaxed typechecking on the ASL "Scope" operator to allow the 7873 1.1 jruoho target name to refer to an object of type Integer, String, or 7874 1.1 jruoho Buffer, in addition to the scoping object types (Device, 7875 1.1 jruoho predefined Scopes, Processor, PowerResource, and ThermalZone.) 7876 1.1 jruoho This allows existing AML code that has workarounds for a bug in 7877 1.1 jruoho Windows to function properly. A warning is issued, however. This 7878 1.1 jruoho affects both the AML interpreter and the iASL compiler. Below is 7879 1.1 jruoho an example of this type of ASL code: 7880 1.1 jruoho 7881 1.1 jruoho Name(DEB,0x00) 7882 1.1 jruoho Scope(DEB) 7883 1.1 jruoho { 7884 1.1 jruoho 7885 1.1 jruoho Fixed some reported problems with 64-bit integer support in the 7886 1.1 jruoho local implementation of C library functions (clib.c) 7887 1.1 jruoho 7888 1.1 jruoho 7889 1.1 jruoho 2) Linux 7890 1.1 jruoho 7891 1.1 jruoho Use ACPI fix map region instead of IOAPIC region, since it is 7892 1.1 jruoho undefined in non-SMP. 7893 1.1 jruoho 7894 1.1 jruoho Ensure that the SCI has the proper polarity and trigger, even on 7895 1.1 jruoho systems that do not have an interrupt override entry in the MADT. 7896 1.1 jruoho 7897 1.1 jruoho 2.5 big driver reorganization (Pat Mochel) 7898 1.1 jruoho 7899 1.1 jruoho Use early table mapping code from acpitable.c (Andi Kleen) 7900 1.1 jruoho 7901 1.1 jruoho New blacklist entries (Andi Kleen) 7902 1.1 jruoho 7903 1.1 jruoho Blacklist improvements. Split blacklist code out into a separate 7904 1.1 jruoho file. Move checking the blacklist to very early. Previously, we 7905 1.1 jruoho would use ACPI tables, and then halfway through init, check the 7906 1.1 jruoho blacklist -- too late. Now, it's early enough to completely fall- 7907 1.1 jruoho back to non-ACPI. 7908 1.1 jruoho 7909 1.1 jruoho 7910 1.1 jruoho 3) iASL Compiler/Disassembler version 20020918: 7911 1.1 jruoho 7912 1.1 jruoho Fixed a problem where the typechecking code didn't know that an 7913 1.1 jruoho alias could point to a method. In other words, aliases were not 7914 1.1 jruoho being dereferenced during typechecking. 7915 1.1 jruoho 7916 1.1 jruoho 7917 1.1 jruoho ---------------------------------------- 7918 1.1 jruoho 29 August 2002. Summary of changes for this release. 7919 1.1 jruoho 7920 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020829: 7921 1.1 jruoho 7922 1.1 jruoho If the target of a Scope() operator already exists, it must be an 7923 1.1 jruoho object type that actually opens a scope -- such as a Device, 7924 1.1 jruoho Method, Scope, etc. This is a fatal runtime error. Similar error 7925 1.1 jruoho check has been added to the iASL compiler also. 7926 1.1 jruoho 7927 1.1 jruoho Tightened up the namespace load to disallow multiple names in the 7928 1.1 jruoho same scope. This previously was allowed if both objects were of 7929 1.1 jruoho the same type. (i.e., a lookup was the same as entering a new 7930 1.1 jruoho name). 7931 1.1 jruoho 7932 1.1 jruoho 7933 1.1 jruoho 2) Linux 7934 1.1 jruoho 7935 1.1 jruoho Ensure that the ACPI interrupt has the proper trigger and 7936 1.1 jruoho polarity. 7937 1.1 jruoho 7938 1.1 jruoho local_irq_disable is extraneous. (Matthew Wilcox) 7939 1.1 jruoho 7940 1.1 jruoho Make "acpi=off" actually do what it says, and not use the ACPI 7941 1.1 jruoho interpreter *or* the tables. 7942 1.1 jruoho 7943 1.1 jruoho Added arch-neutral support for parsing SLIT and SRAT tables (Kochi 7944 1.1 jruoho Takayoshi) 7945 1.1 jruoho 7946 1.1 jruoho 7947 1.1 jruoho 3) iASL Compiler/Disassembler Version 20020829: 7948 1.1 jruoho 7949 1.1 jruoho Implemented namepath optimization for name declarations. For 7950 1.1 jruoho example, a declaration like "Method (\_SB_.ABCD)" would get 7951 1.1 jruoho optimized to "Method (ABCD)" if the declaration is within the 7952 1.1 jruoho \_SB_ scope. This optimization is in addition to the named 7953 1.1 jruoho reference path optimization first released in the previous 7954 1.1 jruoho version. This would seem to complete all possible optimizations 7955 1.1 jruoho for namepaths within the ASL/AML. 7956 1.1 jruoho 7957 1.1 jruoho If the target of a Scope() operator already exists, it must be an 7958 1.1 jruoho object type that actually opens a scope -- such as a Device, 7959 1.1 jruoho Method, Scope, etc. 7960 1.1 jruoho 7961 1.1 jruoho Implemented a check and warning for unreachable code in the same 7962 1.1 jruoho block below a Return() statement. 7963 1.1 jruoho 7964 1.1 jruoho Fixed a problem where the listing file was not generated if the 7965 1.1 jruoho compiler aborted if the maximum error count was exceeded (200). 7966 1.1 jruoho 7967 1.1 jruoho Fixed a problem where the typechecking of method return values was 7968 1.1 jruoho broken. This includes the check for a return value when the 7969 1.1 jruoho method is invoked as a TermArg (a return value is expected.) 7970 1.1 jruoho 7971 1.1 jruoho Fixed a reported problem where EOF conditions during a quoted 7972 1.1 jruoho string or comment caused a fault. 7973 1.1 jruoho 7974 1.1 jruoho 7975 1.1 jruoho ---------------------------------------- 7976 1.1 jruoho 15 August 2002. Summary of changes for this release. 7977 1.1 jruoho 7978 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020815: 7979 1.1 jruoho 7980 1.1 jruoho Fixed a reported problem where a Store to a method argument that 7981 1.1 jruoho contains a reference did not perform the indirect store correctly. 7982 1.1 jruoho This problem was created during the conversion to the new 7983 1.1 jruoho reference object model - the indirect store to a method argument 7984 1.1 jruoho code was not updated to reflect the new model. 7985 1.1 jruoho 7986 1.1 jruoho Reworked the ACPI mode change code to better conform to ACPI 2.0, 7987 1.1 jruoho handle corner cases, and improve code legibility (Kochi Takayoshi) 7988 1.1 jruoho 7989 1.1 jruoho Fixed a problem with the pathname parsing for the carat (^) 7990 1.1 jruoho prefix. The heavy use of the carat operator by the new namepath 7991 1.1 jruoho optimization in the iASL compiler uncovered a problem with the AML 7992 1.1 jruoho interpreter handling of this prefix. In the case where one or 7993 1.1 jruoho more carats precede a single nameseg, the nameseg was treated as 7994 1.1 jruoho standalone and the search rule (to root) was inadvertently 7995 1.1 jruoho applied. This could cause both the iASL compiler and the 7996 1.1 jruoho interpreter to find the wrong object or to miss the error that 7997 1.1 jruoho should occur if the object does not exist at that exact pathname. 7998 1.1 jruoho 7999 1.1 jruoho Found and fixed the problem where the HP Pavilion DSDT would not 8000 1.1 jruoho load. This was a relatively minor tweak to the table loading code 8001 1.1 jruoho (a problem caused by the unexpected encounter with a method 8002 1.1 jruoho invocation not within a control method), but it does not solve the 8003 1.1 jruoho overall issue of the execution of AML code at the table level. 8004 1.1 jruoho This investigation is still ongoing. 8005 1.1 jruoho 8006 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8007 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8008 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8009 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8010 1.1 jruoho version of the code includes the debug output trace mechanism and 8011 1.1 jruoho has a larger code and data size. Note that these values will vary 8012 1.1 jruoho depending on the efficiency of the compiler and the compiler 8013 1.1 jruoho options used during generation. 8014 1.1 jruoho 8015 1.1 jruoho Previous Release 8016 1.1 jruoho Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 8017 1.1 jruoho Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 8018 1.1 jruoho Current Release: 8019 1.1 jruoho Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total 8020 1.1 jruoho Debug Version: 150.0K Code, 61.7K Data, 211.7K Total 8021 1.1 jruoho 8022 1.1 jruoho 8023 1.1 jruoho 2) Linux 8024 1.1 jruoho 8025 1.1 jruoho Remove redundant slab.h include (Brad Hards) 8026 1.1 jruoho 8027 1.1 jruoho Fix several bugs in thermal.c (Herbert Nachtnebel) 8028 1.1 jruoho 8029 1.1 jruoho Make CONFIG_ACPI_BOOT work properly (Pavel Machek) 8030 1.1 jruoho 8031 1.1 jruoho Change acpi_system_suspend to use updated irq functions (Pavel 8032 1.1 jruoho Machek) 8033 1.1 jruoho 8034 1.1 jruoho Export acpi_get_firmware_table (Matthew Wilcox) 8035 1.1 jruoho 8036 1.1 jruoho Use proper root proc entry for ACPI (Kochi Takayoshi) 8037 1.1 jruoho 8038 1.1 jruoho Fix early-boot table parsing (Bjorn Helgaas) 8039 1.1 jruoho 8040 1.1 jruoho 8041 1.1 jruoho 3) iASL Compiler/Disassembler 8042 1.1 jruoho 8043 1.1 jruoho Reworked the compiler options to make them more consistent and to 8044 1.1 jruoho use two-letter options where appropriate. We were running out of 8045 1.1 jruoho sensible letters. This may break some makefiles, so check the 8046 1.1 jruoho current options list by invoking the compiler with no parameters. 8047 1.1 jruoho 8048 1.1 jruoho Completed the design and implementation of the ASL namepath 8049 1.1 jruoho optimization option for the compiler. This option optimizes all 8050 1.1 jruoho references to named objects to the shortest possible path. The 8051 1.1 jruoho first attempt tries to utilize a single nameseg (4 characters) and 8052 1.1 jruoho the "search-to-root" algorithm used by the interpreter. If that 8053 1.1 jruoho cannot be used (because either the name is not in the search path 8054 1.1 jruoho or there is a conflict with another object with the same name), 8055 1.1 jruoho the pathname is optimized using the carat prefix (usually a 8056 1.1 jruoho shorter string than specifying the entire path from the root.) 8057 1.1 jruoho 8058 1.1 jruoho Implemented support to obtain the DSDT from the Windows registry 8059 1.1 jruoho (when the disassembly option is specified with no input file). 8060 1.1 jruoho Added this code as the implementation for AcpiOsTableOverride in 8061 1.1 jruoho the Windows OSL. Migrated the 16-bit code (used in the AcpiDump 8062 1.1 jruoho utility) to scan memory for the DSDT to the AcpiOsTableOverride 8063 1.1 jruoho function in the DOS OSL to make the disassembler truly OS 8064 1.1 jruoho independent. 8065 1.1 jruoho 8066 1.1 jruoho Implemented a new option to disassemble and compile in one step. 8067 1.1 jruoho When used without an input filename, this option will grab the 8068 1.1 jruoho DSDT from the local machine, disassemble it, and compile it in one 8069 1.1 jruoho step. 8070 1.1 jruoho 8071 1.1 jruoho Added a warning message for invalid escapes (a backslash followed 8072 1.1 jruoho by any character other than the allowable escapes). This catches 8073 1.1 jruoho the quoted string error "\_SB_" (which should be "\\_SB_" ). 8074 1.1 jruoho 8075 1.1 jruoho Also, there are numerous instances in the ACPI specification where 8076 1.1 jruoho this error occurs. 8077 1.1 jruoho 8078 1.1 jruoho Added a compiler option to disable all optimizations. This is 8079 1.1 jruoho basically the "compatibility mode" because by using this option, 8080 1.1 jruoho the AML code will come out exactly the same as other ASL 8081 1.1 jruoho compilers. 8082 1.1 jruoho 8083 1.1 jruoho Added error messages for incorrectly ordered dependent resource 8084 1.1 jruoho functions. This includes: missing EndDependentFn macro at end of 8085 1.1 jruoho dependent resource list, nested dependent function macros (both 8086 1.1 jruoho start and end), and missing StartDependentFn macro. These are 8087 1.1 jruoho common errors that should be caught at compile time. 8088 1.1 jruoho 8089 1.1 jruoho Implemented _OSI support for the disassembler and compiler. _OSI 8090 1.1 jruoho must be included in the namespace for proper disassembly (because 8091 1.1 jruoho the disassembler must know the number of arguments.) 8092 1.1 jruoho 8093 1.1 jruoho Added an "optimization" message type that is optional (off by 8094 1.1 jruoho default). This message is used for all optimizations - including 8095 1.1 jruoho constant folding, integer optimization, and namepath optimization. 8096 1.1 jruoho 8097 1.1 jruoho ---------------------------------------- 8098 1.1 jruoho 25 July 2002. Summary of changes for this release. 8099 1.1 jruoho 8100 1.1 jruoho 8101 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020725: 8102 1.1 jruoho 8103 1.1 jruoho The AML Disassembler has been enhanced to produce compilable ASL 8104 1.1 jruoho code and has been integrated into the iASL compiler (see below) as 8105 1.1 jruoho well as the single-step disassembly for the AML debugger and the 8106 1.1 jruoho disassembler for the AcpiDump utility. All ACPI 2.0A opcodes, 8107 1.1 jruoho resource templates and macros are fully supported. The 8108 1.1 jruoho disassembler has been tested on over 30 different AML files, 8109 1.1 jruoho producing identical AML when the resulting disassembled ASL file 8110 1.1 jruoho is recompiled with the same ASL compiler. 8111 1.1 jruoho 8112 1.1 jruoho Modified the Resource Manager to allow zero interrupts and zero 8113 1.1 jruoho dma channels during the GetCurrentResources call. This was 8114 1.1 jruoho causing problems on some platforms. 8115 1.1 jruoho 8116 1.1 jruoho Added the AcpiOsRedirectOutput interface to the OSL to simplify 8117 1.1 jruoho output redirection for the AcpiOsPrintf and AcpiOsVprintf 8118 1.1 jruoho interfaces. 8119 1.1 jruoho 8120 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8121 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8122 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8123 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8124 1.1 jruoho version of the code includes the debug output trace mechanism and 8125 1.1 jruoho has a larger code and data size. Note that these values will vary 8126 1.1 jruoho depending on the efficiency of the compiler and the compiler 8127 1.1 jruoho options used during generation. 8128 1.1 jruoho 8129 1.1 jruoho Previous Release 8130 1.1 jruoho Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 8131 1.1 jruoho Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 8132 1.1 jruoho Current Release: 8133 1.1 jruoho Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 8134 1.1 jruoho Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 8135 1.1 jruoho 8136 1.1 jruoho 8137 1.1 jruoho 2) Linux 8138 1.1 jruoho 8139 1.1 jruoho Fixed a panic in the EC driver (Dominik Brodowski) 8140 1.1 jruoho 8141 1.1 jruoho Implemented checksum of the R/XSDT itself during Linux table scan 8142 1.1 jruoho (Richard Schaal) 8143 1.1 jruoho 8144 1.1 jruoho 8145 1.1 jruoho 3) iASL compiler 8146 1.1 jruoho 8147 1.1 jruoho The AML disassembler is integrated into the compiler. The "-d" 8148 1.1 jruoho option invokes the disassembler to completely disassemble an 8149 1.1 jruoho input AML file, producing as output a text ASL file with the 8150 1.1 jruoho extension ".dsl" (to avoid name collisions with existing .asl 8151 1.1 jruoho source files.) A future enhancement will allow the disassembler 8152 1.1 jruoho to obtain the BIOS DSDT from the registry under Windows. 8153 1.1 jruoho 8154 1.1 jruoho Fixed a problem with the VendorShort and VendorLong resource 8155 1.1 jruoho descriptors where an invalid AML sequence was created. 8156 1.1 jruoho 8157 1.1 jruoho Implemented a fix for BufferData term in the ASL parser. It was 8158 1.1 jruoho inadvertently defined twice, allowing invalid syntax to pass and 8159 1.1 jruoho causing reduction conflicts. 8160 1.1 jruoho 8161 1.1 jruoho Fixed a problem where the Ones opcode could get converted to a 8162 1.1 jruoho value of zero if "Ones" was used where a byte, word or dword value 8163 1.1 jruoho was expected. The 64-bit value is now truncated to the correct 8164 1.1 jruoho size with the correct value. 8165 1.1 jruoho 8166 1.1 jruoho 8167 1.1 jruoho 8168 1.1 jruoho ---------------------------------------- 8169 1.1 jruoho 02 July 2002. Summary of changes for this release. 8170 1.1 jruoho 8171 1.1 jruoho 8172 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020702: 8173 1.1 jruoho 8174 1.1 jruoho The Table Manager code has been restructured to add several new 8175 1.1 jruoho features. Tables that are not required by the core subsystem 8176 1.1 jruoho (other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer 8177 1.1 jruoho validated in any way and are returned from AcpiGetFirmwareTable if 8178 1.1 jruoho requested. The AcpiOsTableOverride interface is now called for 8179 1.1 jruoho each table that is loaded by the subsystem in order to allow the 8180 1.1 jruoho host to override any table it chooses. Previously, only the DSDT 8181 1.1 jruoho could be overridden. Added one new files, tbrsdt.c and 8182 1.1 jruoho tbgetall.c. 8183 1.1 jruoho 8184 1.1 jruoho Fixed a problem with the conversion of internal package objects to 8185 1.1 jruoho external objects (when a package is returned from a control 8186 1.1 jruoho method.) The return buffer length was set to zero instead of the 8187 1.1 jruoho proper length of the package object. 8188 1.1 jruoho 8189 1.1 jruoho Fixed a reported problem with the use of the RefOf and DeRefOf 8190 1.1 jruoho operators when passing reference arguments to control methods. A 8191 1.1 jruoho new type of Reference object is used internally for references 8192 1.1 jruoho produced by the RefOf operator. 8193 1.1 jruoho 8194 1.1 jruoho Added additional error messages in the Resource Manager to explain 8195 1.1 jruoho AE_BAD_DATA errors when they occur during resource parsing. 8196 1.1 jruoho 8197 1.1 jruoho Split the AcpiEnableSubsystem into two primitives to enable a 8198 1.1 jruoho finer granularity initialization sequence. These two calls should 8199 1.1 jruoho be called in this order: AcpiEnableSubsystem (flags), 8200 1.1 jruoho AcpiInitializeObjects (flags). The flags parameter remains the 8201 1.1 jruoho same. 8202 1.1 jruoho 8203 1.1 jruoho 8204 1.1 jruoho 2) Linux 8205 1.1 jruoho 8206 1.1 jruoho Updated the ACPI utilities module to understand the new style of 8207 1.1 jruoho fully resolved package objects that are now returned from the core 8208 1.1 jruoho subsystem. This eliminates errors of the form: 8209 1.1 jruoho 8210 1.1 jruoho ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT] 8211 1.1 jruoho acpi_utils-0430 [145] acpi_evaluate_reference: 8212 1.1 jruoho Invalid element in package (not a device reference) 8213 1.1 jruoho 8214 1.1 jruoho The method evaluation utility uses the new buffer allocation 8215 1.1 jruoho scheme instead of calling AcpiEvaluate Object twice. 8216 1.1 jruoho 8217 1.1 jruoho Added support for ECDT. This allows the use of the Embedded 8218 1.1 jruoho 8219 1.1 jruoho Controller before the namespace has been fully initialized, which 8220 1.1 jruoho is necessary for ACPI 2.0 support, and for some laptops to 8221 1.1 jruoho initialize properly. (Laptops using ECDT are still rare, so only 8222 1.1 jruoho limited testing was performed of the added functionality.) 8223 1.1 jruoho 8224 1.1 jruoho Fixed memory leaks in the EC driver. 8225 1.1 jruoho 8226 1.1 jruoho Eliminated a brittle code structure in acpi_bus_init(). 8227 1.1 jruoho 8228 1.1 jruoho Eliminated the acpi_evaluate() helper function in utils.c. It is 8229 1.1 jruoho no longer needed since acpi_evaluate_object can optionally 8230 1.1 jruoho allocate memory for the return object. 8231 1.1 jruoho 8232 1.1 jruoho Implemented fix for keyboard hang when getting battery readings on 8233 1.1 jruoho some systems (Stephen White) 8234 1.1 jruoho 8235 1.1 jruoho PCI IRQ routing update (Dominik Brodowski) 8236 1.1 jruoho 8237 1.1 jruoho Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC 8238 1.1 jruoho support 8239 1.1 jruoho 8240 1.1 jruoho ---------------------------------------- 8241 1.1 jruoho 11 June 2002. Summary of changes for this release. 8242 1.1 jruoho 8243 1.1 jruoho 8244 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020611: 8245 1.1 jruoho 8246 1.1 jruoho Fixed a reported problem where constants such as Zero and One 8247 1.1 jruoho appearing within _PRT packages were not handled correctly within 8248 1.1 jruoho the resource manager code. Originally reported against the ASL 8249 1.1 jruoho compiler because the code generator now optimizes integers to 8250 1.1 jruoho their minimal AML representation (i.e. AML constants if possible.) 8251 1.1 jruoho The _PRT code now handles all AML constant opcodes correctly 8252 1.1 jruoho (Zero, One, Ones, Revision). 8253 1.1 jruoho 8254 1.1 jruoho Fixed a problem with the Concatenate operator in the AML 8255 1.1 jruoho interpreter where a buffer result object was incorrectly marked as 8256 1.1 jruoho not fully evaluated, causing a run-time error of AE_AML_INTERNAL. 8257 1.1 jruoho 8258 1.1 jruoho All package sub-objects are now fully resolved before they are 8259 1.1 jruoho returned from the external ACPI interfaces. This means that name 8260 1.1 jruoho strings are resolved to object handles, and constant operators 8261 1.1 jruoho (Zero, One, Ones, Revision) are resolved to Integers. 8262 1.1 jruoho 8263 1.1 jruoho Implemented immediate resolution of the AML Constant opcodes 8264 1.1 jruoho (Zero, One, Ones, Revision) to Integer objects upon detection 8265 1.1 jruoho within the AML stream. This has simplified and reduced the 8266 1.1 jruoho generated code size of the subsystem by eliminating about 10 8267 1.1 jruoho switch statements for these constants (which previously were 8268 1.1 jruoho contained in Reference objects.) The complicating issues are that 8269 1.1 jruoho the Zero opcode is used as a "placeholder" for unspecified 8270 1.1 jruoho optional target operands and stores to constants are defined to be 8271 1.1 jruoho no-ops. 8272 1.1 jruoho 8273 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8274 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8275 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8276 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8277 1.1 jruoho version of the code includes the debug output trace mechanism and 8278 1.1 jruoho has a larger code and data size. Note that these values will vary 8279 1.1 jruoho depending on the efficiency of the compiler and the compiler 8280 1.1 jruoho options used during generation. 8281 1.1 jruoho 8282 1.1 jruoho Previous Release 8283 1.1 jruoho Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total 8284 1.1 jruoho Debug Version: 143.8K Code, 58.8K Data, 202.6K Total 8285 1.1 jruoho Current Release: 8286 1.1 jruoho Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 8287 1.1 jruoho Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 8288 1.1 jruoho 8289 1.1 jruoho 8290 1.1 jruoho 2) Linux 8291 1.1 jruoho 8292 1.1 jruoho 8293 1.1 jruoho Added preliminary support for obtaining _TRA data for PCI root 8294 1.1 jruoho bridges (Bjorn Helgaas). 8295 1.1 jruoho 8296 1.1 jruoho 8297 1.1 jruoho 3) iASL Compiler Version X2046: 8298 1.1 jruoho 8299 1.1 jruoho Fixed a problem where the "_DDN" reserved name was defined to be a 8300 1.1 jruoho control method with one argument. There are no arguments, and 8301 1.1 jruoho _DDN does not have to be a control method. 8302 1.1 jruoho 8303 1.1 jruoho Fixed a problem with the Linux version of the compiler where the 8304 1.1 jruoho source lines printed with error messages were the wrong lines. 8305 1.1 jruoho This turned out to be the "LF versus CR/LF" difference between 8306 1.1 jruoho Windows and Unix. This appears to be the longstanding issue 8307 1.1 jruoho concerning listing output and error messages. 8308 1.1 jruoho 8309 1.1 jruoho Fixed a problem with the Linux version of compiler where opcode 8310 1.1 jruoho names within error messages were wrong. This was caused by a 8311 1.1 jruoho slight difference in the output of the Flex tool on Linux versus 8312 1.1 jruoho Windows. 8313 1.1 jruoho 8314 1.1 jruoho Fixed a problem with the Linux compiler where the hex output files 8315 1.1 jruoho contained some garbage data caused by an internal buffer overrun. 8316 1.1 jruoho 8317 1.1 jruoho 8318 1.1 jruoho ---------------------------------------- 8319 1.1 jruoho 17 May 2002. Summary of changes for this release. 8320 1.1 jruoho 8321 1.1 jruoho 8322 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020517: 8323 1.1 jruoho 8324 1.1 jruoho Implemented a workaround to an BIOS bug discovered on the HP 8325 1.1 jruoho OmniBook where the FADT revision number and the table size are 8326 1.1 jruoho inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The new 8327 1.1 jruoho behavior is to fallback to using only the ACPI 1.0 fields of the 8328 1.1 jruoho FADT if the table is too small to be a ACPI 2.0 table as claimed 8329 1.1 jruoho by the revision number. Although this is a BIOS bug, this is a 8330 1.1 jruoho case where the workaround is simple enough and with no side 8331 1.1 jruoho effects, so it seemed prudent to add it. A warning message is 8332 1.1 jruoho issued, however. 8333 1.1 jruoho 8334 1.1 jruoho Implemented minimum size checks for the fixed-length ACPI tables - 8335 1.1 jruoho - the FADT and FACS, as well as consistency checks between the 8336 1.1 jruoho revision number and the table size. 8337 1.1 jruoho 8338 1.1 jruoho Fixed a reported problem in the table override support where the 8339 1.1 jruoho new table pointer was incorrectly treated as a physical address 8340 1.1 jruoho instead of a logical address. 8341 1.1 jruoho 8342 1.1 jruoho Eliminated the use of the AE_AML_ERROR exception and replaced it 8343 1.1 jruoho with more descriptive codes. 8344 1.1 jruoho 8345 1.1 jruoho Fixed a problem where an exception would occur if an ASL Field was 8346 1.1 jruoho defined with no named Field Units underneath it (used by some 8347 1.1 jruoho index fields). 8348 1.1 jruoho 8349 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8350 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8351 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8352 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8353 1.1 jruoho version of the code includes the debug output trace mechanism and 8354 1.1 jruoho has a larger code and data size. Note that these values will vary 8355 1.1 jruoho depending on the efficiency of the compiler and the compiler 8356 1.1 jruoho options used during generation. 8357 1.1 jruoho 8358 1.1 jruoho Previous Release 8359 1.1 jruoho Non-Debug Version: 68.8K Code, 7.1K Data, 75.9K Total 8360 1.1 jruoho Debug Version: 142.9K Code, 58.4K Data, 201.3K Total 8361 1.1 jruoho Current Release: 8362 1.1 jruoho Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total 8363 1.1 jruoho Debug Version: 143.8K Code, 58.8K Data, 202.6K Total 8364 1.1 jruoho 8365 1.1 jruoho 8366 1.1 jruoho 8367 1.1 jruoho 2) Linux 8368 1.1 jruoho 8369 1.1 jruoho Much work done on ACPI init (MADT and PCI IRQ routing support). 8370 1.1 jruoho (Paul D. and Dominik Brodowski) 8371 1.1 jruoho 8372 1.1 jruoho Fix PCI IRQ-related panic on boot (Sam Revitch) 8373 1.1 jruoho 8374 1.1 jruoho Set BM_ARB_DIS when entering a sleep state (Ducrot Bruno) 8375 1.1 jruoho 8376 1.1 jruoho Fix "MHz" typo (Dominik Brodowski) 8377 1.1 jruoho 8378 1.1 jruoho Fix RTC year 2000 issue (Dominik Brodowski) 8379 1.1 jruoho 8380 1.1 jruoho Preclude multiple button proc entries (Eric Brunet) 8381 1.1 jruoho 8382 1.1 jruoho Moved arch-specific code out of include/platform/aclinux.h 8383 1.1 jruoho 8384 1.1 jruoho 3) iASL Compiler Version X2044: 8385 1.1 jruoho 8386 1.1 jruoho Implemented error checking for the string used in the EISAID macro 8387 1.1 jruoho (Usually used in the definition of the _HID object.) The code now 8388 1.1 jruoho strictly enforces the PnP format - exactly 7 characters, 3 8389 1.1 jruoho uppercase letters and 4 hex digits. 8390 1.1 jruoho 8391 1.1 jruoho If a raw string is used in the definition of the _HID object 8392 1.1 jruoho (instead of the EISAID macro), the string must contain all 8393 1.1 jruoho alphanumeric characters (e.g., "*PNP0011" is not allowed because 8394 1.1 jruoho of the asterisk.) 8395 1.1 jruoho 8396 1.1 jruoho Implemented checking for invalid use of ACPI reserved names for 8397 1.1 jruoho most of the name creation operators (Name, Device, Event, Mutex, 8398 1.1 jruoho OperationRegion, PowerResource, Processor, and ThermalZone.) 8399 1.1 jruoho Previously, this check was only performed for control methods. 8400 1.1 jruoho 8401 1.1 jruoho Implemented an additional check on the Name operator to emit an 8402 1.1 jruoho error if a reserved name that must be implemented in ASL as a 8403 1.1 jruoho control method is used. We know that a reserved name must be a 8404 1.1 jruoho method if it is defined with input arguments. 8405 1.1 jruoho 8406 1.1 jruoho The warning emitted when a namespace object reference is not found 8407 1.1 jruoho during the cross reference phase has been changed into an error. 8408 1.1 jruoho The "External" directive should be used for names defined in other 8409 1.1 jruoho modules. 8410 1.1 jruoho 8411 1.1 jruoho 8412 1.1 jruoho 4) Tools and Utilities 8413 1.1 jruoho 8414 1.1 jruoho The 16-bit tools (adump16 and aexec16) have been regenerated and 8415 1.1 jruoho tested. 8416 1.1 jruoho 8417 1.1 jruoho Fixed a problem with the output of both acpidump and adump16 where 8418 1.1 jruoho the indentation of closing parentheses and brackets was not 8419 1.1 jruoho 8420 1.1 jruoho aligned properly with the parent block. 8421 1.1 jruoho 8422 1.1 jruoho 8423 1.1 jruoho ---------------------------------------- 8424 1.1 jruoho 03 May 2002. Summary of changes for this release. 8425 1.1 jruoho 8426 1.1 jruoho 8427 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020503: 8428 1.1 jruoho 8429 1.1 jruoho Added support a new OSL interface that allows the host operating 8430 1.1 jruoho 8431 1.1 jruoho system software to override the DSDT found in the firmware - 8432 1.1 jruoho AcpiOsTableOverride. With this interface, the OSL can examine the 8433 1.1 jruoho version of the firmware DSDT and replace it with a different one 8434 1.1 jruoho if desired. 8435 1.1 jruoho 8436 1.1 jruoho Added new external interfaces for accessing ACPI registers from 8437 1.1 jruoho device drivers and other system software - AcpiGetRegister and 8438 1.1 jruoho AcpiSetRegister. This was simply an externalization of the 8439 1.1 jruoho existing AcpiHwBitRegister interfaces. 8440 1.1 jruoho 8441 1.1 jruoho Fixed a regression introduced in the previous build where the 8442 1.1 jruoho ASL/AML CreateField operator always returned an error, 8443 1.1 jruoho "destination must be a NS Node". 8444 1.1 jruoho 8445 1.1 jruoho Extended the maximum time (before failure) to successfully enable 8446 1.1 jruoho ACPI mode to 3 seconds. 8447 1.1 jruoho 8448 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8449 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8450 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8451 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8452 1.1 jruoho version of the code includes the debug output trace mechanism and 8453 1.1 jruoho has a larger code and data size. Note that these values will vary 8454 1.1 jruoho depending on the efficiency of the compiler and the compiler 8455 1.1 jruoho options used during generation. 8456 1.1 jruoho 8457 1.1 jruoho Previous Release 8458 1.1 jruoho Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total 8459 1.1 jruoho Debug Version: 142.4K Code, 58.3K Data, 200.7K Total 8460 1.1 jruoho Current Release: 8461 1.1 jruoho Non-Debug Version: 68.8K Code, 7.1K Data, 75.9K Total 8462 1.1 jruoho Debug Version: 142.9K Code, 58.4K Data, 201.3K Total 8463 1.1 jruoho 8464 1.1 jruoho 8465 1.1 jruoho 2) Linux 8466 1.1 jruoho 8467 1.1 jruoho Enhanced ACPI init code for SMP. We are now fully MPS and $PIR- 8468 1.1 jruoho free. While 3 out of 4 of our in-house systems work fine, the last 8469 1.1 jruoho one still hangs when testing the LAPIC timer. 8470 1.1 jruoho 8471 1.1 jruoho Renamed many files in 2.5 kernel release to omit "acpi_" from the 8472 1.1 jruoho name. 8473 1.1 jruoho 8474 1.1 jruoho Added warning on boot for Presario 711FR. 8475 1.1 jruoho 8476 1.1 jruoho Sleep improvements (Pavel Machek) 8477 1.1 jruoho 8478 1.1 jruoho ACPI can now be built without CONFIG_PCI enabled. 8479 1.1 jruoho 8480 1.1 jruoho IA64: Fixed memory map functions (JI Lee) 8481 1.1 jruoho 8482 1.1 jruoho 8483 1.1 jruoho 3) iASL Compiler Version X2043: 8484 1.1 jruoho 8485 1.1 jruoho Added support to allow the compiler to be integrated into the MS 8486 1.1 jruoho VC++ development environment for one-button compilation of single 8487 1.1 jruoho files or entire projects -- with error-to-source-line mapping. 8488 1.1 jruoho 8489 1.1 jruoho Implemented support for compile-time constant folding for the 8490 1.1 jruoho Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0 8491 1.1 jruoho specification. This allows the ASL writer to use expressions 8492 1.1 jruoho instead of Integer/Buffer/String constants in terms that must 8493 1.1 jruoho evaluate to constants at compile time and will also simplify the 8494 1.1 jruoho emitted AML in any such sub-expressions that can be folded 8495 1.1 jruoho (evaluated at compile-time.) This increases the size of the 8496 1.1 jruoho compiler significantly because a portion of the ACPI CA AML 8497 1.1 jruoho interpreter is included within the compiler in order to pre- 8498 1.1 jruoho evaluate constant expressions. 8499 1.1 jruoho 8500 1.1 jruoho 8501 1.1 jruoho Fixed a problem with the "Unicode" ASL macro that caused the 8502 1.1 jruoho compiler to fault. (This macro is used in conjunction with the 8503 1.1 jruoho _STR reserved name.) 8504 1.1 jruoho 8505 1.1 jruoho Implemented an AML opcode optimization to use the Zero, One, and 8506 1.1 jruoho Ones opcodes where possible to further reduce the size of integer 8507 1.1 jruoho constants and thus reduce the overall size of the generated AML 8508 1.1 jruoho code. 8509 1.1 jruoho 8510 1.1 jruoho Implemented error checking for new reserved terms for ACPI version 8511 1.1 jruoho 2.0A. 8512 1.1 jruoho 8513 1.1 jruoho Implemented the -qr option to display the current list of ACPI 8514 1.1 jruoho reserved names known to the compiler. 8515 1.1 jruoho 8516 1.1 jruoho Implemented the -qc option to display the current list of ASL 8517 1.1 jruoho operators that are allowed within constant expressions and can 8518 1.1 jruoho therefore be folded at compile time if the operands are constants. 8519 1.1 jruoho 8520 1.1 jruoho 8521 1.1 jruoho 4) Documentation 8522 1.1 jruoho 8523 1.1 jruoho Updated the Programmer's Reference for new interfaces, data types, 8524 1.1 jruoho and memory allocation model options. 8525 1.1 jruoho 8526 1.1 jruoho Updated the iASL Compiler User Reference to apply new format and 8527 1.1 jruoho add information about new features and options. 8528 1.1 jruoho 8529 1.1 jruoho ---------------------------------------- 8530 1.1 jruoho 19 April 2002. Summary of changes for this release. 8531 1.1 jruoho 8532 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020419: 8533 1.1 jruoho 8534 1.1 jruoho The source code base for the Core Subsystem has been completely 8535 1.1 jruoho cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit 8536 1.1 jruoho versions. The Lint option files used are included in the 8537 1.1 jruoho /acpi/generate/lint directory. 8538 1.1 jruoho 8539 1.1 jruoho Implemented enhanced status/error checking across the entire 8540 1.1 jruoho Hardware manager subsystem. Any hardware errors (reported from 8541 1.1 jruoho the OSL) are now bubbled up and will abort a running control 8542 1.1 jruoho method. 8543 1.1 jruoho 8544 1.1 jruoho 8545 1.1 jruoho Fixed a problem where the per-ACPI-table integer width (32 or 64) 8546 1.1 jruoho was stored only with control method nodes, causing a fault when 8547 1.1 jruoho non-control method code was executed during table loading. The 8548 1.1 jruoho solution implemented uses a global variable to indicate table 8549 1.1 jruoho width across the entire ACPI subsystem. Therefore, ACPI CA does 8550 1.1 jruoho not support mixed integer widths across different ACPI tables 8551 1.1 jruoho (DSDT, SSDT). 8552 1.1 jruoho 8553 1.1 jruoho Fixed a problem where NULL extended fields (X fields) in an ACPI 8554 1.1 jruoho 2.0 ACPI FADT caused the table load to fail. Although the 8555 1.1 jruoho existing ACPI specification is a bit fuzzy on this topic, the new 8556 1.1 jruoho behavior is to fall back on a ACPI 1.0 field if the corresponding 8557 1.1 jruoho ACPI 2.0 X field is zero (even though the table revision indicates 8558 1.1 jruoho a full ACPI 2.0 table.) The ACPI specification will be updated to 8559 1.1 jruoho clarify this issue. 8560 1.1 jruoho 8561 1.1 jruoho Fixed a problem with the SystemMemory operation region handler 8562 1.1 jruoho where memory was always accessed byte-wise even if the AML- 8563 1.1 jruoho specified access width was larger than a byte. This caused 8564 1.1 jruoho problems on systems with memory-mapped I/O. Memory is now 8565 1.1 jruoho accessed with the width specified. On systems that do not support 8566 1.1 jruoho non-aligned transfers, a check is made to guarantee proper address 8567 1.1 jruoho alignment before proceeding in order to avoid an AML-caused 8568 1.1 jruoho alignment fault within the kernel. 8569 1.1 jruoho 8570 1.1 jruoho 8571 1.1 jruoho Fixed a problem with the ExtendedIrq resource where only one byte 8572 1.1 jruoho of the 4-byte Irq field was extracted. 8573 1.1 jruoho 8574 1.1 jruoho Fixed the AcpiExDigitsNeeded() procedure to support _UID. This 8575 1.1 jruoho function was out of date and required a rewrite. 8576 1.1 jruoho 8577 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8578 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8579 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8580 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8581 1.1 jruoho version of the code includes the debug output trace mechanism and 8582 1.1 jruoho has a larger code and data size. Note that these values will vary 8583 1.1 jruoho depending on the efficiency of the compiler and the compiler 8584 1.1 jruoho options used during generation. 8585 1.1 jruoho 8586 1.1 jruoho Previous Release 8587 1.1 jruoho Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total 8588 1.1 jruoho Debug Version: 139.8K Code, 57.4K Data, 197.2K Total 8589 1.1 jruoho Current Release: 8590 1.1 jruoho Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total 8591 1.1 jruoho Debug Version: 142.4K Code, 58.3K Data, 200.7K Total 8592 1.1 jruoho 8593 1.1 jruoho 8594 1.1 jruoho 2) Linux 8595 1.1 jruoho 8596 1.1 jruoho PCI IRQ routing fixes (Dominik Brodowski) 8597 1.1 jruoho 8598 1.1 jruoho 8599 1.1 jruoho 3) iASL Compiler Version X2042: 8600 1.1 jruoho 8601 1.1 jruoho Implemented an additional compile-time error check for a field 8602 1.1 jruoho unit whose size + minimum access width would cause a run-time 8603 1.1 jruoho access beyond the end-of-region. Previously, only the field size 8604 1.1 jruoho itself was checked. 8605 1.1 jruoho 8606 1.1 jruoho The Core subsystem and iASL compiler now share a common parse 8607 1.1 jruoho object in preparation for compile-time evaluation of the type 8608 1.1 jruoho 3/4/5 ASL operators. 8609 1.1 jruoho 8610 1.1 jruoho 8611 1.1 jruoho ---------------------------------------- 8612 1.1 jruoho Summary of changes for this release: 03_29_02 8613 1.1 jruoho 8614 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020329: 8615 1.1 jruoho 8616 1.1 jruoho Implemented support for late evaluation of TermArg operands to 8617 1.1 jruoho Buffer and Package objects. This allows complex expressions to be 8618 1.1 jruoho used in the declarations of these object types. 8619 1.1 jruoho 8620 1.1 jruoho Fixed an ACPI 1.0 compatibility issue when reading Fields. In ACPI 8621 1.1 jruoho 1.0, if the field was larger than 32 bits, it was returned as a 8622 1.1 jruoho buffer - otherwise it was returned as an integer. In ACPI 2.0, 8623 1.1 jruoho the field is returned as a buffer only if the field is larger than 8624 1.1 jruoho 64 bits. The TableRevision is now considered when making this 8625 1.1 jruoho conversion to avoid incompatibility with existing ASL code. 8626 1.1 jruoho 8627 1.1 jruoho Implemented logical addressing for AcpiOsGetRootPointer. This 8628 1.1 jruoho allows an RSDP with either a logical or physical address. With 8629 1.1 jruoho this support, the host OS can now override all ACPI tables with 8630 1.1 jruoho one logical RSDP. Includes implementation of "typed" pointer 8631 1.1 jruoho support to allow a common data type for both physical and logical 8632 1.1 jruoho pointers internally. This required a change to the 8633 1.1 jruoho AcpiOsGetRootPointer interface. 8634 1.1 jruoho 8635 1.1 jruoho Implemented the use of ACPI 2.0 Generic Address Structures for all 8636 1.1 jruoho GPE, Fixed Event, and PM Timer I/O. This allows the use of memory 8637 1.1 jruoho mapped I/O for these ACPI features. 8638 1.1 jruoho 8639 1.1 jruoho Initialization now ignores not only non-required tables (All 8640 1.1 jruoho tables other than the FADT, FACS, DSDT, and SSDTs), but also does 8641 1.1 jruoho not validate the table headers of unrecognized tables. 8642 1.1 jruoho 8643 1.1 jruoho Fixed a problem where a notify handler could only be 8644 1.1 jruoho installed/removed on an object of type Device. All "notify" 8645 1.1 jruoho 8646 1.1 jruoho objects are now supported -- Devices, Processor, Power, and 8647 1.1 jruoho Thermal. 8648 1.1 jruoho 8649 1.1 jruoho Removed most verbosity from the ACPI_DB_INFO debug level. Only 8650 1.1 jruoho critical information is returned when this debug level is enabled. 8651 1.1 jruoho 8652 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8653 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8654 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8655 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8656 1.1 jruoho version of the code includes the debug output trace mechanism and 8657 1.1 jruoho has a larger code and data size. Note that these values will vary 8658 1.1 jruoho depending on the efficiency of the compiler and the compiler 8659 1.1 jruoho options used during generation. 8660 1.1 jruoho 8661 1.1 jruoho Previous Release 8662 1.1 jruoho Non-Debug Version: 65.4K Code, 6.2K Data, 71.6K Total 8663 1.1 jruoho Debug Version: 138.0K Code, 56.6K Data, 194.6K Total 8664 1.1 jruoho Current Release: 8665 1.1 jruoho Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total 8666 1.1 jruoho Debug Version: 139.8K Code, 57.4K Data, 197.2K Total 8667 1.1 jruoho 8668 1.1 jruoho 8669 1.1 jruoho 2) Linux: 8670 1.1 jruoho 8671 1.1 jruoho The processor driver (acpi_processor.c) now fully supports ACPI 8672 1.1 jruoho 2.0-based processor performance control (e.g. Intel(R) 8673 1.1 jruoho SpeedStep(TM) technology) Note that older laptops that only have 8674 1.1 jruoho the Intel "applet" interface are not supported through this. The 8675 1.1 jruoho 'limit' and 'performance' interface (/proc) are fully functional. 8676 1.1 jruoho [Note that basic policy for controlling performance state 8677 1.1 jruoho transitions will be included in the next version of ospmd.] The 8678 1.1 jruoho idle handler was modified to more aggressively use C2, and PIIX4 8679 1.1 jruoho errata handling underwent a complete overhaul (big thanks to 8680 1.1 jruoho Dominik Brodowski). 8681 1.1 jruoho 8682 1.1 jruoho Added support for ACPI-PCI device binding (acpi_pci_root.c). _ADR- 8683 1.1 jruoho based devices in the ACPI namespace are now dynamically bound 8684 1.1 jruoho (associated) with their PCI counterparts (e.g. PCI1->01:00.0). 8685 1.1 jruoho This allows, among other things, ACPI to resolve bus numbers for 8686 1.1 jruoho subordinate PCI bridges. 8687 1.1 jruoho 8688 1.1 jruoho Enhanced PCI IRQ routing to get the proper bus number for _PRT 8689 1.1 jruoho entries defined underneath PCI bridges. 8690 1.1 jruoho 8691 1.1 jruoho Added IBM 600E to bad bios list due to invalid _ADR value for 8692 1.1 jruoho PIIX4 PCI-ISA bridge, resulting in improper PCI IRQ routing. 8693 1.1 jruoho 8694 1.1 jruoho In the process of adding full MADT support (e.g. IOAPIC) for IA32 8695 1.1 jruoho (acpi.c, mpparse.c) -- stay tuned. 8696 1.1 jruoho 8697 1.1 jruoho Added back visual differentiation between fixed-feature and 8698 1.1 jruoho control-method buttons in dmesg. Buttons are also subtyped (e.g. 8699 1.1 jruoho button/power/PWRF) to simplify button identification. 8700 1.1 jruoho 8701 1.1 jruoho We no longer use -Wno-unused when compiling debug. Please ignore 8702 1.1 jruoho any "_THIS_MODULE defined but not used" messages. 8703 1.1 jruoho 8704 1.1 jruoho Can now shut down the system using "magic sysrq" key. 8705 1.1 jruoho 8706 1.1 jruoho 8707 1.1 jruoho 3) iASL Compiler version 2041: 8708 1.1 jruoho 8709 1.1 jruoho Fixed a problem where conversion errors for hex/octal/decimal 8710 1.1 jruoho constants were not reported. 8711 1.1 jruoho 8712 1.1 jruoho Implemented a fix for the General Register template Address field. 8713 1.1 jruoho This field was 8 bits when it should be 64. 8714 1.1 jruoho 8715 1.1 jruoho Fixed a problem where errors/warnings were no longer being emitted 8716 1.1 jruoho within the listing output file. 8717 1.1 jruoho 8718 1.1 jruoho Implemented the ACPI 2.0A restriction on ACPI Table Signatures to 8719 1.1 jruoho exactly 4 characters, alphanumeric only. 8720 1.1 jruoho 8721 1.1 jruoho 8722 1.1 jruoho 8723 1.1 jruoho 8724 1.1 jruoho ---------------------------------------- 8725 1.1 jruoho Summary of changes for this release: 03_08_02 8726 1.1 jruoho 8727 1.1 jruoho 8728 1.1 jruoho 1) ACPI CA Core Subsystem Version 20020308: 8729 1.1 jruoho 8730 1.1 jruoho Fixed a problem with AML Fields where the use of the "AccessAny" 8731 1.1 jruoho keyword could cause an interpreter error due to attempting to read 8732 1.1 jruoho or write beyond the end of the parent Operation Region. 8733 1.1 jruoho 8734 1.1 jruoho Fixed a problem in the SystemMemory Operation Region handler where 8735 1.1 jruoho an attempt was made to map memory beyond the end of the region. 8736 1.1 jruoho This was the root cause of the "AE_ERROR" and "AE_NO_MEMORY" 8737 1.1 jruoho errors on some Linux systems. 8738 1.1 jruoho 8739 1.1 jruoho Fixed a problem where the interpreter/namespace "search to root" 8740 1.1 jruoho algorithm was not functioning for some object types. Relaxed the 8741 1.1 jruoho internal restriction on the search to allow upsearches for all 8742 1.1 jruoho external object types as well as most internal types. 8743 1.1 jruoho 8744 1.1 jruoho 8745 1.1 jruoho 2) Linux: 8746 1.1 jruoho 8747 1.1 jruoho We now use safe_halt() macro versus individual calls to sti | hlt. 8748 1.1 jruoho 8749 1.1 jruoho Writing to the processor limit interface should now work. "echo 1" 8750 1.1 jruoho will increase the limit, 2 will decrease, and 0 will reset to the 8751 1.1 jruoho 8752 1.1 jruoho default. 8753 1.1 jruoho 8754 1.1 jruoho 8755 1.1 jruoho 3) ASL compiler: 8756 1.1 jruoho 8757 1.1 jruoho Fixed segfault on Linux version. 8758 1.1 jruoho 8759 1.1 jruoho 8760 1.1 jruoho ---------------------------------------- 8761 1.1 jruoho Summary of changes for this release: 02_25_02 8762 1.1 jruoho 8763 1.1 jruoho 1) ACPI CA Core Subsystem: 8764 1.1 jruoho 8765 1.1 jruoho 8766 1.1 jruoho Fixed a problem where the GPE bit masks were not initialized 8767 1.1 jruoho properly, causing erratic GPE behavior. 8768 1.1 jruoho 8769 1.1 jruoho Implemented limited support for multiple calling conventions. The 8770 1.1 jruoho code can be generated with either the VPL (variable parameter 8771 1.1 jruoho list, or "C") convention, or the FPL (fixed parameter list, or 8772 1.1 jruoho "Pascal") convention. The core subsystem is about 3.4% smaller 8773 1.1 jruoho when generated with FPL. 8774 1.1 jruoho 8775 1.1 jruoho 8776 1.1 jruoho 2) Linux 8777 1.1 jruoho 8778 1.1 jruoho Re-add some /proc/acpi/event functionality that was lost during 8779 1.1 jruoho the rewrite 8780 1.1 jruoho 8781 1.1 jruoho Resolved issue with /proc events for fixed-feature buttons showing 8782 1.1 jruoho up as the system device. 8783 1.1 jruoho 8784 1.1 jruoho Fixed checks on C2/C3 latencies to be inclusive of maximum values. 8785 1.1 jruoho 8786 1.1 jruoho Replaced AE_ERRORs in acpi_osl.c with more specific error codes. 8787 1.1 jruoho 8788 1.1 jruoho Changed ACPI PRT option from "pci=noacpi-routing" to "pci=noacpi" 8789 1.1 jruoho 8790 1.1 jruoho Fixed limit interface & usage to fix bugs with passive cooling 8791 1.1 jruoho hysterisis. 8792 1.1 jruoho 8793 1.1 jruoho Restructured PRT support. 8794 1.1 jruoho 8795 1.1 jruoho 8796 1.1 jruoho ---------------------------------------- 8797 1.1 jruoho Summary of changes for this label: 02_14_02 8798 1.1 jruoho 8799 1.1 jruoho 8800 1.1 jruoho 1) ACPI CA Core Subsystem: 8801 1.1 jruoho 8802 1.1 jruoho Implemented support in AcpiLoadTable to allow loading of FACS and 8803 1.1 jruoho FADT tables. 8804 1.1 jruoho 8805 1.1 jruoho Suport for the now-obsolete interim 0.71 64-bit ACPI tables has 8806 1.1 jruoho been removed. All 64-bit platforms should be migrated to the ACPI 8807 1.1 jruoho 2.0 tables. The actbl71.h header has been removed from the source 8808 1.1 jruoho tree. 8809 1.1 jruoho 8810 1.1 jruoho All C macros defined within the subsystem have been prefixed with 8811 1.1 jruoho "ACPI_" to avoid collision with other system include files. 8812 1.1 jruoho 8813 1.1 jruoho Removed the return value for the two AcpiOsPrint interfaces, since 8814 1.1 jruoho it is never used and causes lint warnings for ignoring the return 8815 1.1 jruoho value. 8816 1.1 jruoho 8817 1.1 jruoho Added error checking to all internal mutex acquire and release 8818 1.1 jruoho calls. Although a failure from one of these interfaces is 8819 1.1 jruoho probably a fatal system error, these checks will cause the 8820 1.1 jruoho immediate abort of the currently executing method or interface. 8821 1.1 jruoho 8822 1.1 jruoho Fixed a problem where the AcpiSetCurrentResources interface could 8823 1.1 jruoho fault. This was a side effect of the deployment of the new memory 8824 1.1 jruoho allocation model. 8825 1.1 jruoho 8826 1.1 jruoho Fixed a couple of problems with the Global Lock support introduced 8827 1.1 jruoho in the last major build. The "common" (1.0/2.0) internal FACS was 8828 1.1 jruoho being overwritten with the FACS signature and clobbering the 8829 1.1 jruoho Global Lock pointer. Also, the actual firmware FACS was being 8830 1.1 jruoho unmapped after construction of the "common" FACS, preventing 8831 1.1 jruoho access to the actual Global Lock field within it. The "common" 8832 1.1 jruoho internal FACS is no longer installed as an actual ACPI table; it 8833 1.1 jruoho is used simply as a global. 8834 1.1 jruoho 8835 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8836 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8837 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8838 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8839 1.1 jruoho version of the code includes the debug output trace mechanism and 8840 1.1 jruoho has a larger code and data size. Note that these values will vary 8841 1.1 jruoho depending on the efficiency of the compiler and the compiler 8842 1.1 jruoho options used during generation. 8843 1.1 jruoho 8844 1.1 jruoho Previous Release (02_07_01) 8845 1.1 jruoho Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total 8846 1.1 jruoho Debug Version: 136.9K Code, 56.4K Data, 193.3K Total 8847 1.1 jruoho Current Release: 8848 1.1 jruoho Non-Debug Version: 65.4K Code, 6.2K Data, 71.6K Total 8849 1.1 jruoho Debug Version: 138.0K Code, 56.6K Data, 194.6K Total 8850 1.1 jruoho 8851 1.1 jruoho 8852 1.1 jruoho 2) Linux 8853 1.1 jruoho 8854 1.1 jruoho Updated Linux-specific code for core macro and OSL interface 8855 1.1 jruoho changes described above. 8856 1.1 jruoho 8857 1.1 jruoho Improved /proc/acpi/event. It now can be opened only once and has 8858 1.1 jruoho proper poll functionality. 8859 1.1 jruoho 8860 1.1 jruoho Fixed and restructured power management (acpi_bus). 8861 1.1 jruoho 8862 1.1 jruoho Only create /proc "view by type" when devices of that class exist. 8863 1.1 jruoho 8864 1.1 jruoho Fixed "charging/discharging" bug (and others) in acpi_battery. 8865 1.1 jruoho 8866 1.1 jruoho Improved thermal zone code. 8867 1.1 jruoho 8868 1.1 jruoho 8869 1.1 jruoho 3) ASL Compiler, version X2039: 8870 1.1 jruoho 8871 1.1 jruoho 8872 1.1 jruoho Implemented the new compiler restriction on ASL String hex/octal 8873 1.1 jruoho escapes to non-null, ASCII values. An error results if an invalid 8874 1.1 jruoho value is used. (This will require an ACPI 2.0 specification 8875 1.1 jruoho change.) 8876 1.1 jruoho 8877 1.1 jruoho AML object labels that are output to the optional C and ASM source 8878 1.1 jruoho are now prefixed with both the ACPI table signature and table ID 8879 1.1 jruoho to help guarantee uniqueness within a large BIOS project. 8880 1.1 jruoho 8881 1.1 jruoho 8882 1.1 jruoho ---------------------------------------- 8883 1.1 jruoho Summary of changes for this label: 02_01_02 8884 1.1 jruoho 8885 1.1 jruoho 1) ACPI CA Core Subsystem: 8886 1.1 jruoho 8887 1.1 jruoho ACPI 2.0 support is complete in the entire Core Subsystem and the 8888 1.1 jruoho ASL compiler. All new ACPI 2.0 operators are implemented and all 8889 1.1 jruoho other changes for ACPI 2.0 support are complete. With 8890 1.1 jruoho simultaneous code and data optimizations throughout the subsystem, 8891 1.1 jruoho ACPI 2.0 support has been implemented with almost no additional 8892 1.1 jruoho cost in terms of code and data size. 8893 1.1 jruoho 8894 1.1 jruoho Implemented a new mechanism for allocation of return buffers. If 8895 1.1 jruoho the buffer length is set to ACPI_ALLOCATE_BUFFER, the buffer will 8896 1.1 jruoho be allocated on behalf of the caller. Consolidated all return 8897 1.1 jruoho buffer validation and allocation to a common procedure. Return 8898 1.1 jruoho buffers will be allocated via the primary OSL allocation interface 8899 1.1 jruoho since it appears that a separate pool is not needed by most users. 8900 1.1 jruoho If a separate pool is required for these buffers, the caller can 8901 1.1 jruoho still use the original mechanism and pre-allocate the buffer(s). 8902 1.1 jruoho 8903 1.1 jruoho Implemented support for string operands within the DerefOf 8904 1.1 jruoho operator. 8905 1.1 jruoho 8906 1.1 jruoho Restructured the Hardware and Event managers to be table driven, 8907 1.1 jruoho simplifying the source code and reducing the amount of generated 8908 1.1 jruoho code. 8909 1.1 jruoho 8910 1.1 jruoho Split the common read/write low-level ACPI register bitfield 8911 1.1 jruoho procedure into a separate read and write, simplifying the code 8912 1.1 jruoho considerably. 8913 1.1 jruoho 8914 1.1 jruoho Obsoleted the AcpiOsCallocate OSL interface. This interface was 8915 1.1 jruoho used only a handful of times and didn't have enough critical mass 8916 1.1 jruoho for a separate interface. Replaced with a common calloc procedure 8917 1.1 jruoho in the core. 8918 1.1 jruoho 8919 1.1 jruoho Fixed a reported problem with the GPE number mapping mechanism 8920 1.1 jruoho that allows GPE1 numbers to be non-contiguous with GPE0. 8921 1.1 jruoho Reorganized the GPE information and shrunk a large array that was 8922 1.1 jruoho originally large enough to hold info for all possible GPEs (256) 8923 1.1 jruoho to simply large enough to hold all GPEs up to the largest GPE 8924 1.1 jruoho number on the machine. 8925 1.1 jruoho 8926 1.1 jruoho Fixed a reported problem with resource structure alignment on 64- 8927 1.1 jruoho bit platforms. 8928 1.1 jruoho 8929 1.1 jruoho Changed the AcpiEnableEvent and AcpiDisableEvent external 8930 1.1 jruoho interfaces to not require any flags for the common case of 8931 1.1 jruoho enabling/disabling a GPE. 8932 1.1 jruoho 8933 1.1 jruoho Implemented support to allow a "Notify" on a Processor object. 8934 1.1 jruoho 8935 1.1 jruoho Most TBDs in comments within the source code have been resolved 8936 1.1 jruoho and eliminated. 8937 1.1 jruoho 8938 1.1 jruoho 8939 1.1 jruoho Fixed a problem in the interpreter where a standalone parent 8940 1.1 jruoho prefix (^) was not handled correctly in the interpreter and 8941 1.1 jruoho debugger. 8942 1.1 jruoho 8943 1.1 jruoho Removed obsolete and unnecessary GPE save/restore code. 8944 1.1 jruoho 8945 1.1 jruoho Implemented Field support in the ASL Load operator. This allows a 8946 1.1 jruoho table to be loaded from a named field, in addition to loading a 8947 1.1 jruoho table directly from an Operation Region. 8948 1.1 jruoho 8949 1.1 jruoho Implemented timeout and handle support in the external Global Lock 8950 1.1 jruoho interfaces. 8951 1.1 jruoho 8952 1.1 jruoho Fixed a problem in the AcpiDump utility where pathnames were no 8953 1.1 jruoho longer being generated correctly during the dump of named objects. 8954 1.1 jruoho 8955 1.1 jruoho Modified the AML debugger to give a full display of if/while 8956 1.1 jruoho predicates instead of just one AML opcode at a time. (The 8957 1.1 jruoho predicate can have several nested ASL statements.) The old method 8958 1.1 jruoho was confusing during single stepping. 8959 1.1 jruoho 8960 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 8961 1.1 jruoho below. These are the code and data sizes for the acpica.lib 8962 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 8963 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 8964 1.1 jruoho version of the code includes the debug output trace mechanism and 8965 1.1 jruoho has a larger code and data size. Note that these values will vary 8966 1.1 jruoho depending on the efficiency of the compiler and the compiler 8967 1.1 jruoho options used during generation. 8968 1.1 jruoho 8969 1.1 jruoho Previous Release (12_18_01) 8970 1.1 jruoho Non-Debug Version: 66.1K Code, 5.5K Data, 71.6K Total 8971 1.1 jruoho Debug Version: 138.3K Code, 55.9K Data, 194.2K Total 8972 1.1 jruoho Current Release: 8973 1.1 jruoho Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total 8974 1.1 jruoho Debug Version: 136.9K Code, 56.4K Data, 193.3K Total 8975 1.1 jruoho 8976 1.1 jruoho 2) Linux 8977 1.1 jruoho 8978 1.1 jruoho Implemented fix for PIIX reverse throttling errata (Processor 8979 1.1 jruoho driver) 8980 1.1 jruoho 8981 1.1 jruoho Added new Limit interface (Processor and Thermal drivers) 8982 1.1 jruoho 8983 1.1 jruoho New thermal policy (Thermal driver) 8984 1.1 jruoho 8985 1.1 jruoho Many updates to /proc 8986 1.1 jruoho 8987 1.1 jruoho Battery "low" event support (Battery driver) 8988 1.1 jruoho 8989 1.1 jruoho Supports ACPI PCI IRQ routing (PCI Link and PCI root drivers) 8990 1.1 jruoho 8991 1.1 jruoho IA32 - IA64 initialization unification, no longer experimental 8992 1.1 jruoho 8993 1.1 jruoho Menuconfig options redesigned 8994 1.1 jruoho 8995 1.1 jruoho 3) ASL Compiler, version X2037: 8996 1.1 jruoho 8997 1.1 jruoho Implemented several new output features to simplify integration of 8998 1.1 jruoho AML code into firmware: 1) Output the AML in C source code with 8999 1.1 jruoho labels for each named ASL object. The original ASL source code 9000 1.1 jruoho is interleaved as C comments. 2) Output the AML in ASM source code 9001 1.1 jruoho with labels and interleaved ASL source. 3) Output the AML in 9002 1.1 jruoho raw hex table form, in either C or ASM. 9003 1.1 jruoho 9004 1.1 jruoho Implemented support for optional string parameters to the 9005 1.1 jruoho LoadTable operator. 9006 1.1 jruoho 9007 1.1 jruoho Completed support for embedded escape sequences within string 9008 1.1 jruoho literals. The compiler now supports all single character escapes 9009 1.1 jruoho as well as the Octal and Hex escapes. Note: the insertion of a 9010 1.1 jruoho null byte into a string literal (via the hex/octal escape) causes 9011 1.1 jruoho the string to be immediately terminated. A warning is issued. 9012 1.1 jruoho 9013 1.1 jruoho Fixed a problem where incorrect AML was generated for the case 9014 1.1 jruoho where an ASL namepath consists of a single parent prefix ( 9015 1.1 jruoho 9016 1.1 jruoho ) with no trailing name segments. 9017 1.1 jruoho 9018 1.1 jruoho The compiler has been successfully generated with a 64-bit C 9019 1.1 jruoho compiler. 9020 1.1 jruoho 9021 1.1 jruoho 9022 1.1 jruoho 9023 1.1 jruoho 9024 1.1 jruoho ---------------------------------------- 9025 1.1 jruoho Summary of changes for this label: 12_18_01 9026 1.1 jruoho 9027 1.1 jruoho 1) Linux 9028 1.1 jruoho 9029 1.1 jruoho Enhanced blacklist with reason and severity fields. Any table's 9030 1.1 jruoho signature may now be used to identify a blacklisted system. 9031 1.1 jruoho 9032 1.1 jruoho Call _PIC control method to inform the firmware which interrupt 9033 1.1 jruoho model the OS is using. Turn on any disabled link devices. 9034 1.1 jruoho 9035 1.1 jruoho Cleaned up busmgr /proc error handling (Andreas Dilger) 9036 1.1 jruoho 9037 1.1 jruoho 2) ACPI CA Core Subsystem: 9038 1.1 jruoho 9039 1.1 jruoho Implemented ACPI 2.0 semantics for the "Break" operator (Exit from 9040 1.1 jruoho while loop) 9041 1.1 jruoho 9042 1.1 jruoho Completed implementation of the ACPI 2.0 "Continue", 9043 1.1 jruoho "ConcatenateResTemplate", "DataTableRegion", and "LoadTable" 9044 1.1 jruoho operators. All new ACPI 2.0 operators are now implemented in both 9045 1.1 jruoho the ASL compiler and the AML interpreter. The only remaining ACPI 9046 1.1 jruoho 2.0 task is support for the String data type in the DerefOf 9047 1.1 jruoho operator. Fixed a problem with AcquireMutex where the status code 9048 1.1 jruoho was lost if the caller had to actually wait for the mutex. 9049 1.1 jruoho 9050 1.1 jruoho Increased the maximum ASL Field size from 64K bits to 4G bits. 9051 1.1 jruoho 9052 1.1 jruoho Completed implementation of the external Global Lock interfaces -- 9053 1.1 jruoho AcpiAcquireGlobalLock and AcpiReleaseGlobalLock. The Timeout and 9054 1.1 jruoho Handler parameters were added. 9055 1.1 jruoho 9056 1.1 jruoho Completed another pass at removing warnings and issues when 9057 1.1 jruoho compiling with 64-bit compilers. The code now compiles cleanly 9058 1.1 jruoho with the Intel 64-bit C/C++ compiler. Most notably, the pointer 9059 1.1 jruoho add and subtract (diff) macros have changed considerably. 9060 1.1 jruoho 9061 1.1 jruoho 9062 1.1 jruoho Created and deployed a new ACPI_SIZE type that is 64-bits wide on 9063 1.1 jruoho 64-bit platforms, 32-bits on all others. This type is used 9064 1.1 jruoho wherever memory allocation and/or the C sizeof() operator is used, 9065 1.1 jruoho and affects the OSL memory allocation interfaces AcpiOsAllocate 9066 1.1 jruoho and AcpiOsCallocate. 9067 1.1 jruoho 9068 1.1 jruoho Implemented sticky user breakpoints in the AML debugger. 9069 1.1 jruoho 9070 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 9071 1.1 jruoho below. These are the code and data sizes for the acpica.lib 9072 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 9073 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 9074 1.1 jruoho version of the code includes the debug output trace mechanism and 9075 1.1 jruoho has a larger code and data size. Note that these values will vary 9076 1.1 jruoho depending on the efficiency of the compiler and the compiler 9077 1.1 jruoho options used during generation. 9078 1.1 jruoho 9079 1.1 jruoho Previous Release (12_05_01) 9080 1.1 jruoho Non-Debug Version: 64.7K Code, 5.3K Data, 70.0K Total 9081 1.1 jruoho Debug Version: 136.2K Code, 55.6K Data, 191.8K Total 9082 1.1 jruoho Current Release: 9083 1.1 jruoho Non-Debug Version: 66.1K Code, 5.5K Data, 71.6K Total 9084 1.1 jruoho Debug Version: 138.3K Code, 55.9K Data, 194.2K Total 9085 1.1 jruoho 9086 1.1 jruoho 3) ASL Compiler, version X2034: 9087 1.1 jruoho 9088 1.1 jruoho Now checks for (and generates an error if detected) the use of a 9089 1.1 jruoho Break or Continue statement without an enclosing While statement. 9090 1.1 jruoho 9091 1.1 jruoho 9092 1.1 jruoho Successfully generated the compiler with the Intel 64-bit C 9093 1.1 jruoho compiler. 9094 1.1 jruoho 9095 1.1 jruoho ---------------------------------------- 9096 1.1 jruoho Summary of changes for this label: 12_05_01 9097 1.1 jruoho 9098 1.1 jruoho 1) ACPI CA Core Subsystem: 9099 1.1 jruoho 9100 1.1 jruoho The ACPI 2.0 CopyObject operator is fully implemented. This 9101 1.1 jruoho operator creates a new copy of an object (and is also used to 9102 1.1 jruoho bypass the "implicit conversion" mechanism of the Store operator.) 9103 1.1 jruoho 9104 1.1 jruoho The ACPI 2.0 semantics for the SizeOf operator are fully 9105 1.1 jruoho implemented. The change is that performing a SizeOf on a 9106 1.1 jruoho reference object causes an automatic dereference of the object to 9107 1.1 jruoho tha actual value before the size is evaluated. This behavior was 9108 1.1 jruoho undefined in ACPI 1.0. 9109 1.1 jruoho 9110 1.1 jruoho The ACPI 2.0 semantics for the Extended IRQ resource descriptor 9111 1.1 jruoho have been implemented. The interrupt polarity and mode are now 9112 1.1 jruoho independently set. 9113 1.1 jruoho 9114 1.1 jruoho Fixed a problem where ASL Constants (Zero, One, Ones, Revision) 9115 1.1 jruoho appearing in Package objects were not properly converted to 9116 1.1 jruoho integers when the internal Package was converted to an external 9117 1.1 jruoho object (via the AcpiEvaluateObject interface.) 9118 1.1 jruoho 9119 1.1 jruoho Fixed a problem with the namespace object deletion mechanism for 9120 1.1 jruoho objects created by control methods. There were two parts to this 9121 1.1 jruoho problem: 1) Objects created during the initialization phase method 9122 1.1 jruoho parse were not being deleted, and 2) The object owner ID mechanism 9123 1.1 jruoho to track objects was broken. 9124 1.1 jruoho 9125 1.1 jruoho Fixed a problem where the use of the ASL Scope operator within a 9126 1.1 jruoho control method would result in an invalid opcode exception. 9127 1.1 jruoho 9128 1.1 jruoho Fixed a problem introduced in the previous label where the buffer 9129 1.1 jruoho length required for the _PRT structure was not being returned 9130 1.1 jruoho correctly. 9131 1.1 jruoho 9132 1.1 jruoho Code and Data Size: Current core subsystem library sizes are shown 9133 1.1 jruoho below. These are the code and data sizes for the acpica.lib 9134 1.1 jruoho produced by the Microsoft Visual C++ 6.0 compiler, and these 9135 1.1 jruoho values do not include any ACPI driver or OSPM code. The debug 9136 1.1 jruoho version of the code includes the debug output trace mechanism and 9137 1.1 jruoho has a larger code and data size. Note that these values will vary 9138 1.1 jruoho depending on the efficiency of the compiler and the compiler 9139 1.1 jruoho options used during generation. 9140 1.1 jruoho 9141 1.1 jruoho Previous Release (11_20_01) 9142 1.1 jruoho Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total 9143 1.1 jruoho Debug Version: 135.1K Code, 55.4K Data, 190.5K Total 9144 1.1 jruoho 9145 1.1 jruoho Current Release: 9146 1.1 jruoho Non-Debug Version: 64.7K Code, 5.3K Data, 70.0K Total 9147 1.1 jruoho Debug Version: 136.2K Code, 55.6K Data, 191.8K Total 9148 1.1 jruoho 9149 1.1 jruoho 2) Linux: 9150 1.1 jruoho 9151 1.1 jruoho Updated all files to apply cleanly against 2.4.16. 9152 1.1 jruoho 9153 1.1 jruoho Added basic PCI Interrupt Routing Table (PRT) support for IA32 9154 1.1 jruoho (acpi_pci.c), and unified the PRT code for IA32 and IA64. This 9155 1.1 jruoho version supports both static and dyanmic PRT entries, but dynamic 9156 1.1 jruoho entries are treated as if they were static (not yet 9157 1.1 jruoho reconfigurable). Architecture- specific code to use this data is 9158 1.1 jruoho absent on IA32 but should be available shortly. 9159 1.1 jruoho 9160 1.1 jruoho Changed the initialization sequence to start the ACPI interpreter 9161 1.1 jruoho (acpi_init) prior to initialization of the PCI driver (pci_init) 9162 1.1 jruoho in init/main.c. This ordering is required to support PRT and 9163 1.1 jruoho facilitate other (future) enhancement. A side effect is that the 9164 1.1 jruoho ACPI bus driver and certain device drivers can no longer be loaded 9165 1.1 jruoho as modules. 9166 1.1 jruoho 9167 1.1 jruoho Modified the 'make menuconfig' options to allow PCI Interrupt 9168 1.1 jruoho Routing support to be included without the ACPI Bus and other 9169 1.1 jruoho device drivers. 9170 1.1 jruoho 9171 1.1 jruoho 3) ASL Compiler, version X2033: 9172 1.1 jruoho 9173 1.1 jruoho Fixed some issues with the use of the new CopyObject and 9174 1.1 jruoho DataTableRegion operators. Both are fully functional. 9175 1.1 jruoho 9176 1.1 jruoho ---------------------------------------- 9177 1.1 jruoho Summary of changes for this label: 11_20_01 9178 1.1 jruoho 9179 1.1 jruoho 20 November 2001. Summary of changes for this release. 9180 1.1 jruoho 9181 1.1 jruoho 1) ACPI CA Core Subsystem: 9182 1.1 jruoho 9183 1.1 jruoho Updated Index support to match ACPI 2.0 semantics. Storing a 9184 1.1 jruoho Integer, String, or Buffer to an Index of a Buffer will store only 9185 1.1 jruoho the least-significant byte of the source to the Indexed buffer 9186 1.1 jruoho byte. Multiple writes are not performed. 9187 1.1 jruoho 9188 1.1 jruoho Fixed a problem where the access type used in an AccessAs ASL 9189 1.1 jruoho operator was not recorded correctly into the field object. 9190 1.1 jruoho 9191 1.1 jruoho Fixed a problem where ASL Event objects were created in a 9192 1.1 jruoho signalled state. Events are now created in an unsignalled state. 9193 1.1 jruoho 9194 1.1 jruoho The internal object cache is now purged after table loading and 9195 1.1 jruoho initialization to reduce the use of dynamic kernel memory -- on 9196 1.1 jruoho the assumption that object use is greatest during the parse phase 9197 1.1 jruoho of the entire table (versus the run-time use of individual control 9198 1.1 jruoho methods.) 9199 1.1 jruoho 9200 1.1 jruoho ACPI 2.0 variable-length packages are now fully operational. 9201 1.1 jruoho 9202 1.1 jruoho Code and Data Size: Code and Data optimizations have permitted new 9203 1.1 jruoho feature development with an actual reduction in the library size. 9204 1.1 jruoho Current core subsystem library sizes are shown below. These are 9205 1.1 jruoho the code and data sizes for the acpica.lib produced by the 9206 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 9207 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 9208 1.1 jruoho includes the debug output trace mechanism and has a larger code 9209 1.1 jruoho and data size. Note that these values will vary depending on the 9210 1.1 jruoho efficiency of the compiler and the compiler options used during 9211 1.1 jruoho generation. 9212 1.1 jruoho 9213 1.1 jruoho Previous Release (11_09_01): 9214 1.1 jruoho Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 9215 1.1 jruoho Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 9216 1.1 jruoho 9217 1.1 jruoho Current Release: 9218 1.1 jruoho Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total 9219 1.1 jruoho Debug Version: 135.1K Code, 55.4K Data, 190.5K Total 9220 1.1 jruoho 9221 1.1 jruoho 2) Linux: 9222 1.1 jruoho 9223 1.1 jruoho Enhanced the ACPI boot-time initialization code to allow the use 9224 1.1 jruoho of Local APIC tables for processor enumeration on IA-32, and to 9225 1.1 jruoho pave the way for a fully MPS-free boot (on SMP systems) in the 9226 1.1 jruoho near future. This functionality replaces 9227 1.1 jruoho arch/i386/kernel/acpitables.c, which was introduced in an earlier 9228 1.1 jruoho 2.4.15-preX release. To enable this feature you must add 9229 1.1 jruoho "acpi_boot=on" to the kernel command line -- see the help entry 9230 1.1 jruoho for CONFIG_ACPI_BOOT for more information. An IA-64 release is in 9231 1.1 jruoho the works... 9232 1.1 jruoho 9233 1.1 jruoho Restructured the configuration options to allow boot-time table 9234 1.1 jruoho parsing support without inclusion of the ACPI Interpreter (and 9235 1.1 jruoho other) code. 9236 1.1 jruoho 9237 1.1 jruoho NOTE: This release does not include fixes for the reported events, 9238 1.1 jruoho power-down, and thermal passive cooling issues (coming soon). 9239 1.1 jruoho 9240 1.1 jruoho 3) ASL Compiler: 9241 1.1 jruoho 9242 1.1 jruoho Added additional typechecking for Fields within restricted access 9243 1.1 jruoho Operation Regions. All fields within EC and CMOS regions must be 9244 1.1 jruoho declared with ByteAcc. All fields withing SMBus regions must be 9245 1.1 jruoho declared with the BufferAcc access type. 9246 1.1 jruoho 9247 1.1 jruoho Fixed a problem where the listing file output of control methods 9248 1.1 jruoho no longer interleaved the actual AML code with the ASL source 9249 1.1 jruoho code. 9250 1.1 jruoho 9251 1.1 jruoho 9252 1.1 jruoho 9253 1.1 jruoho 9254 1.1 jruoho ---------------------------------------- 9255 1.1 jruoho Summary of changes for this label: 11_09_01 9256 1.1 jruoho 9257 1.1 jruoho 1) ACPI CA Core Subsystem: 9258 1.1 jruoho 9259 1.1 jruoho Implemented ACPI 2.0-defined support for writes to fields with a 9260 1.1 jruoho Buffer, String, or Integer source operand that is smaller than the 9261 1.1 jruoho target field. In these cases, the source operand is zero-extended 9262 1.1 jruoho to fill the target field. 9263 1.1 jruoho 9264 1.1 jruoho Fixed a problem where a Field starting bit offset (within the 9265 1.1 jruoho parent operation region) was calculated incorrectly if the 9266 1.1 jruoho 9267 1.1 jruoho alignment of the field differed from the access width. This 9268 1.1 jruoho affected CreateWordField, CreateDwordField, CreateQwordField, and 9269 1.1 jruoho possibly other fields that use the "AccessAny" keyword. 9270 1.1 jruoho 9271 1.1 jruoho Fixed a problem introduced in the 11_02_01 release where indirect 9272 1.1 jruoho stores through method arguments did not operate correctly. 9273 1.1 jruoho 9274 1.1 jruoho 2) Linux: 9275 1.1 jruoho 9276 1.1 jruoho Implemented boot-time ACPI table parsing support 9277 1.1 jruoho (CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code 9278 1.1 jruoho facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than 9279 1.1 jruoho legacy BIOS interfaces (e.g. MPS) for the configuration of system 9280 1.1 jruoho processors, memory, and interrupts during setup_arch(). Note that 9281 1.1 jruoho this patch does not include the required architecture-specific 9282 1.1 jruoho changes required to apply this information -- subsequent patches 9283 1.1 jruoho will be posted for both IA32 and IA64 to achieve this. 9284 1.1 jruoho 9285 1.1 jruoho Added low-level sleep support for IA32 platforms, courtesy of Pat 9286 1.1 jruoho Mochel. This allows IA32 systems to transition to/from various 9287 1.1 jruoho sleeping states (e.g. S1, S3), although the lack of a centralized 9288 1.1 jruoho driver model and power-manageable drivers will prevent its 9289 1.1 jruoho (successful) use on most systems. 9290 1.1 jruoho 9291 1.1 jruoho Revamped the ACPI 'menuconfig' layout: created new "ACPI Support" 9292 1.1 jruoho submenu, unified IA32 and IA64 options, added new "Boot using ACPI 9293 1.1 jruoho tables" option, etc. 9294 1.1 jruoho 9295 1.1 jruoho Increased the default timeout for the EC driver from 1ms to 10ms 9296 1.1 jruoho (1000 cycles of 10us) to try to address AE_TIME errors during EC 9297 1.1 jruoho transactions. 9298 1.1 jruoho 9299 1.1 jruoho ---------------------------------------- 9300 1.1 jruoho Summary of changes for this label: 11_02_01 9301 1.1 jruoho 9302 1.1 jruoho 1) ACPI CA Core Subsystem: 9303 1.1 jruoho 9304 1.1 jruoho ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access 9305 1.1 jruoho (QWordAcc keyword). All ACPI 2.0 64-bit support is now 9306 1.1 jruoho implemented. 9307 1.1 jruoho 9308 1.1 jruoho OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required 9309 1.1 jruoho changes to support ACPI 2.0 Qword field access. Read/Write 9310 1.1 jruoho PciConfiguration(), Read/Write Memory(), and Read/Write Port() now 9311 1.1 jruoho accept an ACPI_INTEGER (64 bits) as the value parameter. Also, 9312 1.1 jruoho the value parameter for the address space handler interface is now 9313 1.1 jruoho an ACPI_INTEGER. OSL implementations of these interfaces must now 9314 1.1 jruoho handle the case where the Width parameter is 64. 9315 1.1 jruoho 9316 1.1 jruoho Index Fields: Fixed a problem where unaligned bit assembly and 9317 1.1 jruoho disassembly for IndexFields was not supported correctly. 9318 1.1 jruoho 9319 1.1 jruoho Index and Bank Fields: Nested Index and Bank Fields are now 9320 1.1 jruoho supported. During field access, a check is performed to ensure 9321 1.1 jruoho that the value written to an Index or Bank register is not out of 9322 1.1 jruoho the range of the register. The Index (or Bank) register is 9323 1.1 jruoho written before each access to the field data. Future support will 9324 1.1 jruoho include allowing individual IndexFields to be wider than the 9325 1.1 jruoho DataRegister width. 9326 1.1 jruoho 9327 1.1 jruoho Fields: Fixed a problem where the AML interpreter was incorrectly 9328 1.1 jruoho attempting to write beyond the end of a Field/OpRegion. This was 9329 1.1 jruoho a boundary case that occurred when a DWORD field was written to a 9330 1.1 jruoho BYTE access OpRegion, forcing multiple writes and causing the 9331 1.1 jruoho interpreter to write one datum too many. 9332 1.1 jruoho 9333 1.1 jruoho Fields: Fixed a problem with Field/OpRegion access where the 9334 1.1 jruoho starting bit address of a field was incorrectly calculated if the 9335 1.1 jruoho current access type was wider than a byte (WordAcc, DwordAcc, or 9336 1.1 jruoho QwordAcc). 9337 1.1 jruoho 9338 1.1 jruoho Fields: Fixed a problem where forward references to individual 9339 1.1 jruoho FieldUnits (individual Field names within a Field definition) were 9340 1.1 jruoho not resolved during the AML table load. 9341 1.1 jruoho 9342 1.1 jruoho Fields: Fixed a problem where forward references from a Field 9343 1.1 jruoho definition to the parent Operation Region definition were not 9344 1.1 jruoho resolved during the AML table load. 9345 1.1 jruoho 9346 1.1 jruoho Fields: Duplicate FieldUnit names within a scope are now detected 9347 1.1 jruoho during AML table load. 9348 1.1 jruoho 9349 1.1 jruoho Acpi Interfaces: Fixed a problem where the AcpiGetName() interface 9350 1.1 jruoho returned an incorrect name for the root node. 9351 1.1 jruoho 9352 1.1 jruoho Code and Data Size: Code and Data optimizations have permitted new 9353 1.1 jruoho feature development with an actual reduction in the library size. 9354 1.1 jruoho Current core subsystem library sizes are shown below. These are 9355 1.1 jruoho the code and data sizes for the acpica.lib produced by the 9356 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 9357 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 9358 1.1 jruoho includes the debug output trace mechanism and has a larger code 9359 1.1 jruoho and data size. Note that these values will vary depending on the 9360 1.1 jruoho efficiency of the compiler and the compiler options used during 9361 1.1 jruoho generation. 9362 1.1 jruoho 9363 1.1 jruoho Previous Release (10_18_01): 9364 1.1 jruoho Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total 9365 1.1 jruoho Debug Version: 136.7K Code, 57.4K Data, 194.2K Total 9366 1.1 jruoho 9367 1.1 jruoho Current Release: 9368 1.1 jruoho Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 9369 1.1 jruoho Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 9370 1.1 jruoho 9371 1.1 jruoho 2) Linux: 9372 1.1 jruoho 9373 1.1 jruoho Improved /proc processor output (Pavel Machek) Re-added 9374 1.1 jruoho MODULE_LICENSE("GPL") to all modules. 9375 1.1 jruoho 9376 1.1 jruoho 3) ASL Compiler version X2030: 9377 1.1 jruoho 9378 1.1 jruoho Duplicate FieldUnit names within a scope are now detected and 9379 1.1 jruoho flagged as errors. 9380 1.1 jruoho 9381 1.1 jruoho 4) Documentation: 9382 1.1 jruoho 9383 1.1 jruoho Programmer Reference updated to reflect OSL and address space 9384 1.1 jruoho handler interface changes described above. 9385 1.1 jruoho 9386 1.1 jruoho ---------------------------------------- 9387 1.1 jruoho Summary of changes for this label: 10_18_01 9388 1.1 jruoho 9389 1.1 jruoho ACPI CA Core Subsystem: 9390 1.1 jruoho 9391 1.1 jruoho Fixed a problem with the internal object reference count mechanism 9392 1.1 jruoho that occasionally caused premature object deletion. This resolves 9393 1.1 jruoho all of the outstanding problem reports where an object is deleted 9394 1.1 jruoho in the middle of an interpreter evaluation. Although this problem 9395 1.1 jruoho only showed up in rather obscure cases, the solution to the 9396 1.1 jruoho problem involved an adjustment of all reference counts involving 9397 1.1 jruoho objects attached to namespace nodes. 9398 1.1 jruoho 9399 1.1 jruoho Fixed a problem with Field support in the interpreter where 9400 1.1 jruoho writing to an aligned field whose length is an exact multiple (2 9401 1.1 jruoho or greater) of the field access granularity would cause an attempt 9402 1.1 jruoho to write beyond the end of the field. 9403 1.1 jruoho 9404 1.1 jruoho The top level AML opcode execution functions within the 9405 1.1 jruoho interpreter have been renamed with a more meaningful and 9406 1.1 jruoho consistent naming convention. The modules exmonad.c and 9407 1.1 jruoho exdyadic.c were eliminated. New modules are exoparg1.c, 9408 1.1 jruoho exoparg2.c, exoparg3.c, and exoparg6.c. 9409 1.1 jruoho 9410 1.1 jruoho Support for the ACPI 2.0 "Mid" ASL operator has been implemented. 9411 1.1 jruoho 9412 1.1 jruoho Fixed a problem where the AML debugger was causing some internal 9413 1.1 jruoho objects to not be deleted during subsystem termination. 9414 1.1 jruoho 9415 1.1 jruoho Fixed a problem with the external AcpiEvaluateObject interface 9416 1.1 jruoho where the subsystem would fault if the named object to be 9417 1.1 jruoho evaluated refered to a constant such as Zero, Ones, etc. 9418 1.1 jruoho 9419 1.1 jruoho Fixed a problem with IndexFields and BankFields where the 9420 1.1 jruoho subsystem would fault if the index, data, or bank registers were 9421 1.1 jruoho not defined in the same scope as the field itself. 9422 1.1 jruoho 9423 1.1 jruoho Added printf format string checking for compilers that support 9424 1.1 jruoho this feature. Corrected more than 50 instances of issues with 9425 1.1 jruoho format specifiers within invocations of ACPI_DEBUG_PRINT 9426 1.1 jruoho throughout the core subsystem code. 9427 1.1 jruoho 9428 1.1 jruoho The ASL "Revision" operator now returns the ACPI support level 9429 1.1 jruoho implemented in the core - the value "2" since the ACPI 2.0 support 9430 1.1 jruoho is more than 50% implemented. 9431 1.1 jruoho 9432 1.1 jruoho Enhanced the output of the AML debugger "dump namespace" command 9433 1.1 jruoho to output in a more human-readable form. 9434 1.1 jruoho 9435 1.1 jruoho Current core subsystem library code sizes are shown below. These 9436 1.1 jruoho 9437 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 9438 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 9439 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 9440 1.1 jruoho includes the full debug trace mechanism -- leading to a much 9441 1.1 jruoho 9442 1.1 jruoho larger code and data size. Note that these values will vary 9443 1.1 jruoho depending on the efficiency of the compiler and the compiler 9444 1.1 jruoho options used during generation. 9445 1.1 jruoho 9446 1.1 jruoho Previous Label (09_20_01): 9447 1.1 jruoho Non-Debug Version: 65K Code, 5K Data, 70K Total 9448 1.1 jruoho Debug Version: 138K Code, 58K Data, 196K Total 9449 1.1 jruoho 9450 1.1 jruoho This Label: 9451 1.1 jruoho 9452 1.1 jruoho Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total 9453 1.1 jruoho Debug Version: 136.7K Code, 57.4K Data, 194.2K Total 9454 1.1 jruoho 9455 1.1 jruoho Linux: 9456 1.1 jruoho 9457 1.1 jruoho Implemented a "Bad BIOS Blacklist" to track machines that have 9458 1.1 jruoho known ASL/AML problems. 9459 1.1 jruoho 9460 1.1 jruoho Enhanced the /proc interface for the thermal zone driver and added 9461 1.1 jruoho support for _HOT (the critical suspend trip point). The 'info' 9462 1.1 jruoho file now includes threshold/policy information, and allows setting 9463 1.1 jruoho of _SCP (cooling preference) and _TZP (polling frequency) values 9464 1.1 jruoho to the 'info' file. Examples: "echo tzp=5 > info" sets the polling 9465 1.1 jruoho frequency to 5 seconds, and "echo scp=1 > info" sets the cooling 9466 1.1 jruoho preference to the passive/quiet mode (if supported by the ASL). 9467 1.1 jruoho 9468 1.1 jruoho Implemented a workaround for a gcc bug that resuted in an OOPs 9469 1.1 jruoho when loading the control method battery driver. 9470 1.1 jruoho 9471 1.1 jruoho ---------------------------------------- 9472 1.1 jruoho Summary of changes for this label: 09_20_01 9473 1.1 jruoho 9474 1.1 jruoho ACPI CA Core Subsystem: 9475 1.1 jruoho 9476 1.1 jruoho The AcpiEnableEvent and AcpiDisableEvent interfaces have been 9477 1.1 jruoho modified to allow individual GPE levels to be flagged as wake- 9478 1.1 jruoho enabled (i.e., these GPEs are to remain enabled when the platform 9479 1.1 jruoho sleeps.) 9480 1.1 jruoho 9481 1.1 jruoho The AcpiEnterSleepState and AcpiLeaveSleepState interfaces now 9482 1.1 jruoho support wake-enabled GPEs. This means that upon entering the 9483 1.1 jruoho sleep state, all GPEs that are not wake-enabled are disabled. 9484 1.1 jruoho When leaving the sleep state, these GPEs are reenabled. 9485 1.1 jruoho 9486 1.1 jruoho A local double-precision divide/modulo module has been added to 9487 1.1 jruoho enhance portability to OS kernels where a 64-bit math library is 9488 1.1 jruoho not available. The new module is "utmath.c". 9489 1.1 jruoho 9490 1.1 jruoho Several optimizations have been made to reduce the use of CPU 9491 1.1 jruoho stack. Originally over 2K, the maximum stack usage is now below 9492 1.1 jruoho 2K at 1860 bytes (1.82k) 9493 1.1 jruoho 9494 1.1 jruoho Fixed a problem with the AcpiGetFirmwareTable interface where the 9495 1.1 jruoho root table pointer was not mapped into a logical address properly. 9496 1.1 jruoho 9497 1.1 jruoho Fixed a problem where a NULL pointer was being dereferenced in the 9498 1.1 jruoho interpreter code for the ASL Notify operator. 9499 1.1 jruoho 9500 1.1 jruoho Fixed a problem where the use of the ASL Revision operator 9501 1.1 jruoho returned an error. This operator now returns the current version 9502 1.1 jruoho of the ACPI CA core subsystem. 9503 1.1 jruoho 9504 1.1 jruoho Fixed a problem where objects passed as control method parameters 9505 1.1 jruoho to AcpiEvaluateObject were always deleted at method termination. 9506 1.1 jruoho However, these objects may end up being stored into the namespace 9507 1.1 jruoho by the called method. The object reference count mechanism was 9508 1.1 jruoho applied to these objects instead of a force delete. 9509 1.1 jruoho 9510 1.1 jruoho Fixed a problem where static strings or buffers (contained in the 9511 1.1 jruoho AML code) that are declared as package elements within the ASL 9512 1.1 jruoho code could cause a fault because the interpreter would attempt to 9513 1.1 jruoho delete them. These objects are now marked with the "static 9514 1.1 jruoho object" flag to prevent any attempt to delete them. 9515 1.1 jruoho 9516 1.1 jruoho Implemented an interpreter optimization to use operands directly 9517 1.1 jruoho from the state object instead of extracting the operands to local 9518 1.1 jruoho variables. This reduces stack use and code size, and improves 9519 1.1 jruoho performance. 9520 1.1 jruoho 9521 1.1 jruoho The module exxface.c was eliminated as it was an unnecessary extra 9522 1.1 jruoho layer of code. 9523 1.1 jruoho 9524 1.1 jruoho Current core subsystem library code sizes are shown below. These 9525 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 9526 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 9527 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 9528 1.1 jruoho includes the full debug trace mechanism -- leading to a much 9529 1.1 jruoho larger code and data size.

The implicit function return value (not the 9556 1.1 jruoho explicit store operands) was returning the remainder instead of 9557 1.1 jruoho the quotient. This was a longstanding bug and it fixes several 9558 1.1 jruoho known outstanding issues on various platforms. 9559 1.1 jruoho 9560 1.1 jruoho The ACPI_DEBUG_PRINT and function trace entry/exit macros have 9561 1.1 jruoho been further optimized for size. There are 700 invocations of the 9562 1.1 jruoho DEBUG_PRINT macro alone, so each optimization reduces the size of 9563 1.1 jruoho the debug version of the subsystem significantly. 9564 1.1 jruoho 9565 1.1 jruoho A stack trace mechanism has been implemented. The maximum stack 9566 1.1 jruoho usage is about 2K on 32-bit platforms. The debugger command "stat 9567 1.1 jruoho stack" will display the current maximum stack usage. 9568 1.1 jruoho 9569 1.1 jruoho All public symbols and global variables within the subsystem are 9570 1.1 jruoho now prefixed with the string "Acpi". This keeps all of the 9571 1.1 jruoho symbols grouped together in a kernel map, and avoids conflicts 9572 1.1 jruoho with other kernel subsystems. 9573 1.1 jruoho 9574 1.1 jruoho Most of the internal fixed lookup tables have been moved into the 9575 1.1 jruoho code segment via the const operator. 9576 1.1 jruoho 9577 1.1 jruoho Several enhancements have been made to the interpreter to both 9578 1.1 jruoho reduce the code size and improve performance. 9579 1.1 jruoho 9580 1.1 jruoho Current core subsystem library code sizes are shown below. These 9581 1.1 jruoho are the code and data sizes for the acpica.lib produced by the 9582 1.1 jruoho Microsoft Visual C++ 6.0 compiler, and these values do not include 9583 1.1 jruoho any ACPI driver or OSPM code. The debug version of the code 9584 1.1 jruoho includes the full debug trace mechanism which contains over 700 9585 1.1 jruoho invocations of the DEBUG_PRINT macro, 500 function entry macro 9586 1.1 jruoho invocations, and over 900 function exit macro invocations -- 9587 1.1 jruoho leading to a much larger code and data size. Note that these 9588 1.1 jruoho values will vary depending on the efficiency of the compiler and 9589 1.1 jruoho the compiler options used during generation. 9590 1.1 jruoho 9591 1.1 jruoho Non-Debug Version: 64K Code, 5K Data, 69K Total 9592 1.1 jruoho Debug Version: 137K Code, 58K Data, 195K Total 9593 1.1 jruoho 9594 1.1 jruoho Linux: 9595 1.1 jruoho 9596 1.1 jruoho Implemented wbinvd() macro, pending a kernel-wide definition. 9597 1.1 jruoho 9598 1.1 jruoho Fixed /proc/acpi/event to handle poll() and short reads. 9599 1.1 jruoho 9600 1.1 jruoho ASL Compiler, version X2026: 9601 1.1 jruoho 9602 1.1 jruoho Fixed a problem introduced in the previous label where the AML 9603 1.1 jruoho 9604 1.1 jruoho code emitted for package objects produced packages with zero 9605 1.1 jruoho length. 9606 1.1 jruoho 9607 1.1 jruoho ---------------------------------------- 9608 1.1 jruoho Summary of changes for this label: 08_16_01 9609 1.1 jruoho 9610 1.1 jruoho ACPI CA Core Subsystem: 9611 1.1 jruoho 9612 1.1 jruoho The following ACPI 2.0 ASL operators have been implemented in the 9613 1.1 jruoho AML interpreter (These are already supported by the Intel ASL 9614 1.1 jruoho compiler): ToDecimalString, ToHexString, ToString, ToInteger, and 9615 1.1 jruoho ToBuffer. Support for 64-bit AML constants is implemented in the 9616 1.1 jruoho AML parser, debugger, and disassembler. 9617 1.1 jruoho 9618 1.1 jruoho The internal memory tracking mechanism (leak detection code) has 9619 1.1 jruoho been upgraded to reduce the memory overhead (a separate tracking 9620 1.1 jruoho block is no longer allocated for each memory allocation), and now 9621 1.1 jruoho supports all of the internal object caches. 9622 1.1 jruoho 9623 1.1 jruoho The data structures and code for the internal object caches have 9624 1.1 jruoho been coelesced and optimized so that there is a single cache and 9625 1.1 jruoho memory list data structure and a single group of functions that 9626 1.1 jruoho implement generic cache management. This has reduced the code 9627 1.1 jruoho size in both the debug and release versions of the subsystem. 9628 1.1 jruoho 9629 1.1 jruoho The DEBUG_PRINT macro(s) have been optimized for size and replaced 9630 1.1 jruoho by ACPI_DEBUG_PRINT. The syntax for this macro is slightly 9631 1.1 jruoho different, because it generates a single call to an internal 9632 1.1 jruoho function. This results in a savings of about 90 bytes per 9633 1.1 jruoho invocation, resulting in an overall code and data savings of about 9634 1.1 jruoho 16% in the debug version of the subsystem. 9635 1.1 jruoho 9636 1.1 jruoho Linux: 9637 1.1 jruoho 9638 1.1 jruoho Fixed C3 disk corruption problems and re-enabled C3 on supporting 9639 1.1 jruoho machines. 9640 1.1 jruoho 9641 1.1 jruoho Integrated low-level sleep code by Patrick Mochel. 9642 1.1 jruoho 9643 1.1 jruoho Further tweaked source code Linuxization. 9644 1.1 jruoho 9645 1.1 jruoho Other minor fixes. 9646 1.1 jruoho 9647 1.1 jruoho ASL Compiler: 9648 1.1 jruoho 9649 1.1 jruoho Support for ACPI 2.0 variable length packages is fixed/completed. 9650 1.1 jruoho 9651 1.1 jruoho Fixed a problem where the optional length parameter for the ACPI 9652 1.1 jruoho 2.0 ToString operator. 9653 1.1 jruoho 9654 1.1 jruoho Fixed multiple extraneous error messages when a syntax error is 9655 1.1 jruoho detected within the declaration line of a control method. 9656 1.1 jruoho 9657 1.1 jruoho ---------------------------------------- 9658 1.1 jruoho Summary of changes for this label: 07_17_01 9659 1.1 jruoho 9660 1.1 jruoho ACPI CA Core Subsystem: 9661 1.1 jruoho 9662 1.1 jruoho Added a new interface named AcpiGetFirmwareTable to obtain any 9663 1.1 jruoho ACPI table via the ACPI signature. The interface can be called at 9664 1.1 jruoho any time during kernel initialization, even before the kernel 9665 1.1 jruoho virtual memory manager is initialized and paging is enabled. This 9666 1.1 jruoho allows kernel subsystems to obtain ACPI tables very early, even 9667 1.1 jruoho before the ACPI CA subsystem is initialized. 9668 1.1 jruoho 9669 1.1 jruoho Fixed a problem where Fields defined with the AnyAcc attribute 9670 1.1 jruoho could be resolved to the incorrect address under the following 9671 1.1 jruoho conditions: 1) the field width is larger than 8 bits and 2) the 9672 1.1 jruoho parent operation region is not defined on a DWORD boundary. 9673 1.1 jruoho 9674 1.1 jruoho Fixed a problem where the interpreter is not being locked during 9675 1.1 jruoho namespace initialization (during execution of the _INI control 9676 1.1 jruoho methods), causing an error when an attempt is made to release it 9677 1.1 jruoho later. 9678 1.1 jruoho 9679 1.1 jruoho ACPI 2.0 support in the AML Interpreter has begun and will be 9680 1.1 jruoho ongoing throughout the rest of this year. In this label, The Mod 9681 1.1 jruoho operator is implemented. 9682 1.1 jruoho 9683 1.1 jruoho Added a new data type to contain full PCI addresses named 9684 1.1 jruoho ACPI_PCI_ID. This structure contains the PCI Segment, Bus, Device, 9685 1.1 jruoho and Function values. 9686 1.1 jruoho 9687 1.1 jruoho Linux: 9688 1.1 jruoho 9689 1.1 jruoho Enhanced the Linux version of the source code to change most 9690 1.1 jruoho capitalized ACPI type names to lowercase. For example, all 9691 1.1 jruoho instances of ACPI_STATUS are changed to acpi_status. This will 9692 1.1 jruoho result in a large diff, but the change is strictly cosmetic and 9693 1.1 jruoho aligns the CA code closer to the Linux coding standard. 9694 1.1 jruoho 9695 1.1 jruoho OSL Interfaces: 9696 1.1 jruoho 9697 1.1 jruoho The interfaces to the PCI configuration space have been changed to 9698 1.1 jruoho add the PCI Segment number and to split the single 32-bit combined 9699 1.1 jruoho DeviceFunction field into two 16-bit fields. This was 9700 1.1 jruoho accomplished by moving the four values that define an address in 9701 1.1 jruoho PCI configuration space (segment, bus, device, and function) to 9702 1.1 jruoho the new ACPI_PCI_ID structure. 9703 1.1 jruoho 9704 1.1 jruoho The changes to the PCI configuration space interfaces led to a 9705 1.1 jruoho reexamination of the complete set of address space access 9706 1.1 jruoho interfaces for PCI, I/O, and Memory. The previously existing 18 9707 1.1 jruoho interfaces have proven difficult to maintain (any small change 9708 1.1 jruoho must be propagated across at least 6 interfaces) and do not easily 9709 1.1 jruoho allow for future expansion to 64 bits if necessary. Also, on some 9710 1.1 jruoho systems, it would not be appropriate to demultiplex the access 9711 1.1 jruoho width (8, 16, 32,or 64) before calling the OSL if the 9712 1.1 jruoho corresponding native OS interfaces contain a similar access width 9713 1.1 jruoho parameter. For these reasons, the 18 address space interfaces 9714 1.1 jruoho have been replaced by these 6 new ones: 9715 1.1 jruoho 9716 1.1 jruoho AcpiOsReadPciConfiguration 9717 1.1 jruoho AcpiOsWritePciConfiguration 9718 1.1 jruoho AcpiOsReadMemory 9719 1.1 jruoho AcpiOsWriteMemory 9720 1.1 jruoho AcpiOsReadPort 9721 1.1 jruoho AcpiOsWritePort 9722 1.1 jruoho 9723 1.1 jruoho Added a new interface named AcpiOsGetRootPointer to allow the OSL 9724 1.1 jruoho to perform the platform and/or OS-specific actions necessary to 9725 1.1 jruoho obtain the ACPI RSDP table pointer. On IA-32 platforms, this 9726 1.1 jruoho interface will simply call down to the CA core to perform the low- 9727 1.1 jruoho memory search for the table. On IA-64, the RSDP is obtained from 9728 1.1 jruoho EFI. Migrating this interface to the OSL allows the CA core to 9729 1.1 jruoho 9730 1.1 jruoho remain OS and platform independent. 9731 1.1 jruoho 9732 1.1 jruoho Added a new interface named AcpiOsSignal to provide a generic 9733 1.1 jruoho "function code and pointer" interface for various miscellaneous 9734 1.1 jruoho signals and notifications that must be made to the host OS. The 9735 1.1 jruoho first such signals are intended to support the ASL Fatal and 9736 1.1 jruoho Breakpoint operators. In the latter case, the AcpiOsBreakpoint 9737 1.1 jruoho interface has been obsoleted. 9738 1.1 jruoho 9739 1.1 jruoho The definition of the AcpiFormatException interface has been 9740 1.1 jruoho changed to simplify its use. The caller no longer must supply a 9741 1.1 jruoho buffer to the call; A pointer to a const string is now returned 9742 1.1 jruoho directly. This allows the call to be easily used in printf 9743 1.1 jruoho statements, etc. since the caller does not have to manage a local 9744 1.1 jruoho buffer. 9745 1.1 jruoho 9746 1.1 jruoho 9747 1.1 jruoho ASL Compiler, Version X2025: 9748 1.1 jruoho 9749 1.1 jruoho The ACPI 2.0 Switch/Case/Default operators have been implemented 9750 1.1 jruoho and are fully functional. They will work with all ACPI 1.0 9751 1.1 jruoho interpreters, since the operators are simply translated to If/Else 9752 1.1 jruoho pairs. 9753 1.1 jruoho 9754 1.1 jruoho The ACPI 2.0 ElseIf operator is implemented and will also work 9755 1.1 jruoho with 1.0 interpreters, for the same reason. 9756 1.1 jruoho 9757 1.1 jruoho Implemented support for ACPI 2.0 variable-length packages. These 9758 1.1 jruoho packages have a separate opcode, and their size is determined by 9759 1.1 jruoho the interpreter at run-time. 9760 1.1 jruoho 9761 1.1 jruoho Documentation The ACPI CA Programmer Reference has been updated to 9762 1.1 jruoho reflect the new interfaces and changes to existing interfaces. 9763 1.1 jruoho 9764 1.1 jruoho ------------------------------------------ 9765 1.1 jruoho Summary of changes for this label: 06_15_01 9766 1.1 jruoho 9767 1.1 jruoho ACPI CA Core Subsystem: 9768 1.1 jruoho 9769 1.1 jruoho Fixed a problem where a DWORD-accessed field within a Buffer 9770 1.1 jruoho object would get its byte address inadvertently rounded down to 9771 1.1 jruoho the nearest DWORD. Buffers are always Byte-accessible. 9772 1.1 jruoho 9773 1.1 jruoho ASL Compiler, version X2024: 9774 1.1 jruoho 9775 1.1 jruoho Fixed a problem where the Switch() operator would either fault or 9776 1.1 jruoho hang the compiler. Note however, that the AML code for this ACPI 9777 1.1 jruoho 2.0 operator is not yet implemented. 9778 1.1 jruoho 9779 1.1 jruoho Compiler uses the new AcpiOsGetTimer interface to obtain compile 9780 1.1 jruoho timings. 9781 1.1 jruoho 9782 1.1 jruoho Implementation of the CreateField operator automatically converts 9783 1.1 jruoho a reference to a named field within a resource descriptor from a 9784 1.1 jruoho byte offset to a bit offset if required. 9785 1.1 jruoho 9786 1.1 jruoho Added some missing named fields from the resource descriptor 9787 1.1 jruoho support. These are the names that are automatically created by the 9788 1.1 jruoho compiler to reference fields within a descriptor. They are only 9789 1.1 jruoho valid at compile time and are not passed through to the AML 9790 1.1 jruoho interpreter. 9791 1.1 jruoho 9792 1.1 jruoho Resource descriptor named fields are now typed as Integers and 9793 1.1 jruoho subject to compile-time typechecking when used in expressions. 9794 1.1 jruoho 9795 1.1 jruoho ------------------------------------------ 9796 1.1 jruoho Summary of changes for this label: 05_18_01 9797 1.1 jruoho 9798 1.1 jruoho ACPI CA Core Subsystem: 9799 1.1 jruoho 9800 1.1 jruoho Fixed a couple of problems in the Field support code where bits 9801 1.1 jruoho from adjacent fields could be returned along with the proper field 9802 1.1 jruoho bits. Restructured the field support code to improve performance, 9803 1.1 jruoho readability and maintainability. 9804 1.1 jruoho 9805 1.1 jruoho New DEBUG_PRINTP macro automatically inserts the procedure name 9806 1.1 jruoho into the output, saving hundreds of copies of procedure name 9807 1.1 jruoho strings within the source, shrinking the memory footprint of the 9808 1.1 jruoho debug version of the core subsystem. 9809 1.1 jruoho 9810 1.1 jruoho Source Code Structure: 9811 1.1 jruoho 9812 1.1 jruoho The source code directory tree was restructured to reflect the 9813 1.1 jruoho current organization of the component architecture. Some files 9814 1.1 jruoho and directories have been moved and/or renamed. 9815 1.1 jruoho 9816 1.1 jruoho Linux: 9817 1.1 jruoho 9818 1.1 jruoho Fixed leaking kacpidpc processes. 9819 1.1 jruoho 9820 1.1 jruoho Fixed queueing event data even when /proc/acpi/event is not 9821 1.1 jruoho opened. 9822 1.1 jruoho 9823 1.1 jruoho ASL Compiler, version X2020: 9824 1.1 jruoho 9825 1.1 jruoho Memory allocation performance enhancement - over 24X compile time 9826 1.1 jruoho improvement on large ASL files. Parse nodes and namestring 9827 1.1 jruoho buffers are now allocated from a large internal compiler buffer. 9828 1.1 jruoho 9829 1.1 jruoho The temporary .SRC file is deleted unless the "-s" option is 9830 1.1 jruoho specified 9831 1.1 jruoho 9832 1.1 jruoho The "-d" debug output option now sends all output to the .DBG file 9833 1.1 jruoho instead of the console. 9834 1.1 jruoho 9835 1.1 jruoho "External" second parameter is now optional 9836 1.1 jruoho 9837 1.1 jruoho "ElseIf" syntax now properly allows the predicate 9838 1.1 jruoho 9839 1.1 jruoho Last operand to "Load" now recognized as a Target operand 9840 1.1 jruoho 9841 1.1 jruoho Debug object can now be used anywhere as a normal object. 9842 1.1 jruoho 9843 1.1 jruoho ResourceTemplate now returns an object of type BUFFER 9844 1.1 jruoho 9845 1.1 jruoho EISAID now returns an object of type INTEGER 9846 1.1 jruoho 9847 1.1 jruoho "Index" now works with a STRING operand 9848 1.1 jruoho 9849 1.1 jruoho "LoadTable" now accepts optional parameters 9850 1.1 jruoho 9851 1.1 jruoho "ToString" length parameter is now optional 9852 1.1 jruoho 9853 1.1 jruoho "Interrupt (ResourceType," parse error fixed. 9854 1.1 jruoho 9855 1.1 jruoho "Register" with a user-defined region space parse error fixed 9856 1.1 jruoho 9857 1.1 jruoho Escaped backslash at the end of a string ("\\") scan/parse error 9858 1.1 jruoho fixed 9859 1.1 jruoho 9860 1.1 jruoho "Revision" is now an object of type INTEGER. 9861 1.1 jruoho 9862 1.1 jruoho 9863 1.1 jruoho 9864 1.1 jruoho ------------------------------------------ 9865 1.1 jruoho Summary of changes for this label: 05_02_01 9866 1.1 jruoho 9867 1.1 jruoho Linux: 9868 1.1 jruoho 9869 1.1 jruoho /proc/acpi/event now blocks properly. 9870 1.1 jruoho 9871 1.1 jruoho Removed /proc/sys/acpi. You can still dump your DSDT from 9872 1.1 jruoho /proc/acpi/dsdt. 9873 1.1 jruoho 9874 1.1 jruoho ACPI CA Core Subsystem: 9875 1.1 jruoho 9876 1.1 jruoho Fixed a problem introduced in the previous label where some of the 9877 1.1 jruoho "small" resource descriptor types were not recognized. 9878 1.1 jruoho 9879 1.1 jruoho Improved error messages for the case where an ASL Field is outside 9880 1.1 jruoho the range of the parent operation region. 9881 1.1 jruoho 9882 1.1 jruoho ASL Compiler, version X2018: 9883 1.1 jruoho 9884 1.1 jruoho 9885 1.1 jruoho Added error detection for ASL Fields that extend beyond the length 9886 1.1 jruoho of the parent operation region (only if the length of the region 9887 1.1 jruoho is known at compile time.) This includes fields that have a 9888 1.1 jruoho minimum access width that is smaller than the parent region, and 9889 1.1 jruoho individual field units that are partially or entirely beyond the 9890 1.1 jruoho extent of the parent. 9891 1.1 jruoho 9892 1.1 jruoho 9893 1.1 jruoho 9894 1.1 jruoho ------------------------------------------ 9895 1.1 jruoho Summary of changes for this label: 04_27_01 9896 1.1 jruoho 9897 1.1 jruoho ACPI CA Core Subsystem: 9898 1.1 jruoho 9899 1.1 jruoho Fixed a problem where the namespace mutex could be released at the 9900 1.1 jruoho wrong time during execution of AcpiRemoveAddressSpaceHandler. 9901 1.1 jruoho 9902 1.1 jruoho Added optional thread ID output for debug traces, to simplify 9903 1.1 jruoho debugging of multiple threads. Added context switch notification 9904 1.1 jruoho when the debug code realizes that a different thread is now 9905 1.1 jruoho executing ACPI code. 9906 1.1 jruoho 9907 1.1 jruoho Some additional external data types have been prefixed with the 9908 1.1 jruoho string "ACPI_" for consistency. This may effect existing code. 9909 1.1 jruoho The data types affected are the external callback typedefs - e.g., 9910 1.1 jruoho 9911 1.1 jruoho WALK_CALLBACK becomes ACPI_WALK_CALLBACK. 9912 1.1 jruoho 9913 1.1 jruoho Linux: 9914 1.1 jruoho 9915 1.1 jruoho Fixed an issue with the OSL semaphore implementation where a 9916 1.1 jruoho thread was waking up with an error from receiving a SIGCHLD 9917 1.1 jruoho signal. 9918 1.1 jruoho 9919 1.1 jruoho Linux version of ACPI CA now uses the system C library for string 9920 1.1 jruoho manipulation routines instead of a local implementation. 9921 1.1 jruoho 9922 1.1 jruoho Cleaned up comments and removed TBDs. 9923 1.1 jruoho 9924 1.1 jruoho ASL Compiler, version X2017: 9925 1.1 jruoho 9926 1.1 jruoho Enhanced error detection and reporting for all file I/O 9927 1.1 jruoho operations. 9928 1.1 jruoho 9929 1.1 jruoho Documentation: 9930 1.1 jruoho 9931 1.1 jruoho Programmer Reference updated to version 1.06. 9932 1.1 jruoho 9933 1.1 jruoho 9934 1.1 jruoho 9935 1.1 jruoho ------------------------------------------ 9936 1.1 jruoho Summary of changes for this label: 04_13_01 9937 1.1 jruoho 9938 1.1 jruoho ACPI CA Core Subsystem: 9939 1.1 jruoho 9940 1.1 jruoho Restructured support for BufferFields and RegionFields. 9941 1.1 jruoho BankFields support is now fully operational. All known 32-bit 9942 1.1 jruoho limitations on field sizes have been removed. Both BufferFields 9943 1.1 jruoho and (Operation) RegionFields are now supported by the same field 9944 1.1 jruoho management code. 9945 1.1 jruoho 9946 1.1 jruoho Resource support now supports QWORD address and IO resources. The 9947 1.1 jruoho 16/32/64 bit address structures and the Extended IRQ structure 9948 1.1 jruoho have been changed to properly handle Source Resource strings. 9949 1.1 jruoho 9950 1.1 jruoho A ThreadId of -1 is now used to indicate a "mutex not acquired" 9951 1.1 jruoho condition internally and must never be returned by AcpiOsThreadId. 9952 1.1 jruoho This reserved value was changed from 0 since Unix systems allow a 9953 1.1 jruoho thread ID of 0. 9954 1.1 jruoho 9955 1.1 jruoho Linux: 9956 1.1 jruoho 9957 1.1 jruoho Driver code reorganized to enhance portability 9958 1.1 jruoho 9959 1.1 jruoho Added a kernel configuration option to control ACPI_DEBUG 9960 1.1 jruoho 9961 1.1 jruoho Fixed the EC driver to honor _GLK. 9962 1.1 jruoho 9963 1.1 jruoho ASL Compiler, version X2016: 9964 1.1 jruoho 9965 1.1 jruoho Fixed support for the "FixedHw" keyword. Previously, the FixedHw 9966 1.1 jruoho address space was set to 0, not 0x7f as it should be. 9967 1.1 jruoho 9968 1.1 jruoho ------------------------------------------ 9969 1.1 jruoho Summary of changes for this label: 03_13_01 9970 1.1 jruoho 9971 1.1 jruoho ACPI CA Core Subsystem: 9972 1.1 jruoho 9973 1.1 jruoho During ACPI initialization, the _SB_._INI method is now run if 9974 1.1 jruoho present. 9975 1.1 jruoho 9976 1.1 jruoho Notify handler fix - notifies are deferred until the parent method 9977 1.1 jruoho completes execution. This fixes the "mutex already acquired" 9978 1.1 jruoho issue seen occasionally. 9979 1.1 jruoho 9980 1.1 jruoho Part of the "implicit conversion" rules in ACPI 2.0 have been 9981 1.1 jruoho found to cause compatibility problems with existing ASL/AML. The 9982 1.1 jruoho convert "result-to-target-type" implementation has been removed 9983 1.1 jruoho for stores to method Args and Locals. Source operand conversion 9984 1.1 jruoho is still fully implemented. Possible changes to ACPI 2.0 9985 1.1 jruoho specification pending. 9986 1.1 jruoho 9987 1.1 jruoho Fix to AcpiRsCalculatePciRoutingTableLength to return correct 9988 1.1 jruoho length. 9989 1.1 jruoho 9990 1.1 jruoho Fix for compiler warnings for 64-bit compiles. 9991 1.1 jruoho 9992 1.1 jruoho Linux: 9993 1.1 jruoho 9994 1.1 jruoho /proc output aligned for easier parsing. 9995 1.1 jruoho 9996 1.1 jruoho Release-version compile problem fixed. 9997 1.1 jruoho 9998 1.1 jruoho New kernel configuration options documented in Configure.help. 9999 1.1 jruoho 10000 1.1 jruoho IBM 600E - Fixed Sleep button may generate "Invalid <NULL> 10001 1.1 jruoho context" message. 10002 1.1 jruoho 10003 1.1 jruoho OSPM: 10004 1.1 jruoho 10005 1.1 jruoho Power resource driver integrated with bus manager. 10006 1.1 jruoho 10007 1.1 jruoho Fixed kernel fault during active cooling for thermal zones. 10008 1.1 jruoho 10009 1.1 jruoho Source Code: 10010 1.1 jruoho 10011 1.1 jruoho The source code tree has been restructured. 10012 1.1 jruoho 10013 1.1 jruoho 10014 1.1 jruoho 10015 1.1 jruoho ------------------------------------------ 10016 1.1 jruoho Summary of changes for this label: 03_02_01 10017 1.1 jruoho 10018 1.1 jruoho Linux OS Services Layer (OSL): 10019 1.1 jruoho 10020 1.1 jruoho Major revision of all Linux-specific code. 10021 1.1 jruoho 10022 1.1 jruoho Modularized all ACPI-specific drivers. 10023 1.1 jruoho 10024 1.1 jruoho Added new thermal zone and power resource drivers. 10025 1.1 jruoho 10026 1.1 jruoho Revamped /proc interface (new functionality is under /proc/acpi). 10027 1.1 jruoho 10028 1.1 jruoho New kernel configuration options. 10029 1.1 jruoho 10030 1.1 jruoho Linux known issues: 10031 1.1 jruoho 10032 1.1 jruoho New kernel configuration options not documented in Configure.help 10033 1.1 jruoho yet. 10034 1.1 jruoho 10035 1.1 jruoho 10036 1.1 jruoho Module dependencies not currently implemented. If used, they 10037 1.1 jruoho should be loaded in this order: busmgr, power, ec, system, 10038 1.1 jruoho processor, battery, ac_adapter, button, thermal. 10039 1.1 jruoho 10040 1.1 jruoho Modules will not load if CONFIG_MODVERSION is set. 10041 1.1 jruoho 10042 1.1 jruoho IBM 600E - entering S5 may reboot instead of shutting down. 10043 1.1 jruoho 10044 1.1 jruoho IBM 600E - Sleep button may generate "Invalid <NULL> context" 10045 1.1 jruoho message. 10046 1.1 jruoho 10047 1.1 jruoho Some systems may fail with "execution mutex already acquired" 10048 1.1 jruoho message. 10049 1.1 jruoho 10050 1.1 jruoho ACPI CA Core Subsystem: 10051 1.1 jruoho 10052 1.1 jruoho Added a new OSL Interface, AcpiOsGetThreadId. This was required 10053 1.1 jruoho for the deadlock detection code. Defined to return a non-zero, 32- 10054 1.1 jruoho bit thread ID for the currently executing thread. May be a non- 10055 1.1 jruoho zero constant integer on single-thread systems. 10056 1.1 jruoho 10057 1.1 jruoho Implemented deadlock detection for internal subsystem mutexes. We 10058 1.1 jruoho may add conditional compilation for this code (debug only) later. 10059 1.1 jruoho 10060 1.1 jruoho ASL/AML Mutex object semantics are now fully supported. This 10061 1.1 jruoho includes multiple acquires/releases by owner and support for the 10062 1.1 jruoho 10063 1.1 jruoho Mutex SyncLevel parameter. 10064 1.1 jruoho 10065 1.1 jruoho A new "Force Release" mechanism automatically frees all ASL 10066 1.1 jruoho Mutexes that have been acquired but not released when a thread 10067 1.1 jruoho exits the interpreter. This forces conformance to the ACPI spec 10068 1.1 jruoho ("All mutexes must be released when an invocation exits") and 10069 1.1 jruoho prevents deadlocked ASL threads. This mechanism can be expanded 10070 1.1 jruoho (later) to monitor other resource acquisitions if OEM ASL code 10071 1.1 jruoho continues to misbehave (which it will). 10072 1.1 jruoho 10073 1.1 jruoho Several new ACPI exception codes have been added for the Mutex 10074 1.1 jruoho support. 10075 1.1 jruoho 10076 1.1 jruoho Recursive method calls are now allowed and supported (the ACPI 10077 1.1 jruoho spec does in fact allow recursive method calls.) The number of 10078 1.1 jruoho recursive calls is subject to the restrictions imposed by the 10079 1.1 jruoho SERIALIZED method keyword and SyncLevel (ACPI 2.0) method 10080 1.1 jruoho parameter. 10081 1.1 jruoho 10082 1.1 jruoho Implemented support for the SyncLevel parameter for control 10083 1.1 jruoho methods (ACPI 2.0 feature) 10084 1.1 jruoho 10085 1.1 jruoho Fixed a deadlock problem when multiple threads attempted to use 10086 1.1 jruoho the interpreter. 10087 1.1 jruoho 10088 1.1 jruoho Fixed a problem where the string length of a String package 10089 1.1 jruoho element was not always set in a package returned from 10090 1.1 jruoho AcpiEvaluateObject. 10091 1.1 jruoho 10092 1.1 jruoho Fixed a problem where the length of a String package element was 10093 1.1 jruoho not always included in the length of the overall package returned 10094 1.1 jruoho from AcpiEvaluateObject. 10095 1.1 jruoho 10096 1.1 jruoho Added external interfaces (Acpi*) to the ACPI debug memory 10097 1.1 jruoho manager. This manager keeps a list of all outstanding 10098 1.1 jruoho allocations, and can therefore detect memory leaks and attempts to 10099 1.1 jruoho free memory blocks more than once. Useful for code such as the 10100 1.1 jruoho power manager, etc. May not be appropriate for device drivers. 10101 1.1 jruoho Performance with the debug code enabled is slow. 10102 1.1 jruoho 10103 1.1 jruoho The ACPI Global Lock is now an optional hardware element. 10104 1.1 jruoho 10105 1.1 jruoho ASL Compiler Version X2015: 10106 1.1 jruoho 10107 1.1 jruoho Integrated changes to allow the compiler to be generated on 10108 1.1 jruoho multiple platforms. 10109 1.1 jruoho 10110 1.1 jruoho Linux makefile added to generate the compiler on Linux 10111 1.1 jruoho 10112 1.1 jruoho Source Code: 10113 1.1 jruoho 10114 1.1 jruoho All platform-specific headers have been moved to their own 10115 1.1 jruoho subdirectory, Include/Platform. 10116 1.1 jruoho 10117 1.1 jruoho New source file added, Interpreter/ammutex.c 10118 1.1 jruoho 10119 1.1 jruoho New header file, Include/acstruct.h 10120 1.1 jruoho 10121 1.1 jruoho Documentation: 10122 1.1 jruoho 10123 1.1 jruoho The programmer reference has been updated for the following new 10124 1.1 jruoho interfaces: AcpiOsGetThreadId AcpiAllocate AcpiCallocate AcpiFree 10125 1.1 jruoho 10126 1.1 jruoho ------------------------------------------ 10127 1.1 jruoho Summary of changes for this label: 02_08_01 10128 1.1 jruoho 10129 1.1 jruoho Core ACPI CA Subsystem: Fixed a problem where an error was 10130 1.1 jruoho incorrectly returned if the return resource buffer was larger than 10131 1.1 jruoho the actual data (in the resource interfaces). 10132 1.1 jruoho 10133 1.1 jruoho References to named objects within packages are resolved to the 10134 1.1 jruoho 10135 1.1 jruoho full pathname string before packages are returned directly (via 10136 1.1 jruoho the AcpiEvaluateObject interface) or indirectly via the resource 10137 1.1 jruoho interfaces. 10138 1.1 jruoho 10139 1.1 jruoho Linux OS Services Layer (OSL): 10140 1.1 jruoho 10141 1.1 jruoho Improved /proc battery interface. 10142 1.1 jruoho 10143 1.1 jruoho 10144 1.1 jruoho Added C-state debugging output and other miscellaneous fixes. 10145 1.1 jruoho 10146 1.1 jruoho ASL Compiler Version X2014: 10147 1.1 jruoho 10148 1.1 jruoho All defined method arguments can now be used as local variables, 10149 1.1 jruoho including the ones that are not actually passed in as parameters. 10150 1.1 jruoho The compiler tracks initialization of the arguments and issues an 10151 1.1 jruoho exception if they are used without prior assignment (just like 10152 1.1 jruoho locals). 10153 1.1 jruoho 10154 1.1 jruoho The -o option now specifies a filename prefix that is used for all 10155 1.1 jruoho output files, including the AML output file. Otherwise, the 10156 1.1 jruoho default behavior is as follows: 1) the AML goes to the file 10157 1.1 jruoho specified in the DSDT. 2) all other output files use the input 10158 1.1 jruoho source filename as the base. 10159 1.1 jruoho 10160 1.1 jruoho ------------------------------------------ 10161 1.1 jruoho Summary of changes for this label: 01_25_01 10162 1.1 jruoho 10163 1.1 jruoho Core ACPI CA Subsystem: Restructured the implementation of object 10164 1.1 jruoho store support within the interpreter. This includes support for 10165 1.1 jruoho the Store operator as well as any ASL operators that include a 10166 1.1 jruoho target operand. 10167 1.1 jruoho 10168 1.1 jruoho Partially implemented support for Implicit Result-to-Target 10169 1.1 jruoho conversion. This is when a result object is converted on the fly 10170 1.1 jruoho to the type of an existing target object. Completion of this 10171 1.1 jruoho support is pending further analysis of the ACPI specification 10172 1.1 jruoho concerning this matter. 10173 1.1 jruoho 10174 1.1 jruoho CPU-specific code has been removed from the subsystem (hardware 10175 1.1 jruoho directory). 10176 1.1 jruoho 10177 1.1 jruoho New Power Management Timer functions added 10178 1.1 jruoho 10179 1.1 jruoho Linux OS Services Layer (OSL): Moved system state transition code 10180 1.1 jruoho to the core, fixed it, and modified Linux OSL accordingly. 10181 1.1 jruoho 10182 1.1 jruoho Fixed C2 and C3 latency calculations. 10183 1.1 jruoho 10184 1.1 jruoho 10185 1.1 jruoho We no longer use the compilation date for the version message on 10186 1.1 jruoho initialization, but retrieve the version from AcpiGetSystemInfo(). 10187 1.1 jruoho 10188 1.1 jruoho Incorporated for fix Sony VAIO machines. 10189 1.1 jruoho 10190 1.1 jruoho Documentation: The Programmer Reference has been updated and 10191 1.1 jruoho reformatted. 10192 1.1 jruoho 10193 1.1 jruoho 10194 1.1 jruoho ASL Compiler: Version X2013: Fixed a problem where the line 10195 1.1 jruoho numbering and error reporting could get out of sync in the 10196 1.1 jruoho presence of multiple include files. 10197 1.1 jruoho 10198 1.1 jruoho ------------------------------------------ 10199 1.1 jruoho Summary of changes for this label: 01_15_01 10200 1.1 jruoho 10201 1.1 jruoho Core ACPI CA Subsystem: 10202 1.1 jruoho 10203 1.1 jruoho Implemented support for type conversions in the execution of the 10204 1.1 jruoho ASL Concatenate operator (The second operand is converted to 10205 1.1 jruoho match the type of the first operand before concatenation.) 10206 1.1 jruoho 10207 1.1 jruoho Support for implicit source operand conversion is partially 10208 1.1 jruoho implemented. The ASL source operand types Integer, Buffer, and 10209 1.1 jruoho String are freely interchangeable for most ASL operators and are 10210 1.1 jruoho converted by the interpreter on the fly as required. Implicit 10211 1.1 jruoho Target operand conversion (where the result is converted to the 10212 1.1 jruoho target type before storing) is not yet implemented. 10213 1.1 jruoho 10214 1.1 jruoho Support for 32-bit and 64-bit BCD integers is implemented. 10215 1.1 jruoho 10216 1.1 jruoho Problem fixed where a field read on an aligned field could cause a 10217 1.1 jruoho read past the end of the field. 10218 1.1 jruoho 10219 1.1 jruoho New exception, AE_AML_NO_RETURN_VALUE, is returned when a method 10220 1.1 jruoho does not return a value, but the caller expects one. (The ASL 10221 1.1 jruoho compiler flags this as a warning.) 10222 1.1 jruoho 10223 1.1 jruoho ASL Compiler: 10224 1.1 jruoho 10225 1.1 jruoho Version X2011: 10226 1.1 jruoho 1. Static typechecking of all operands is implemented. This 10227 1.1 jruoho prevents the use of invalid objects (such as using a Package where 10228 1.1 jruoho an Integer is required) at compile time instead of at interpreter 10229 1.1 jruoho run-time. 10230 1.1 jruoho 2. The ASL source line is printed with ALL errors and warnings. 10231 1.1 jruoho 3. Bug fix for source EOF without final linefeed. 10232 1.1 jruoho 4. Debug option is split into a parse trace and a namespace trace. 10233 1.1 jruoho 5. Namespace output option (-n) includes initial values for 10234 1.1 jruoho integers and strings. 10235 1.1 jruoho 6. Parse-only option added for quick syntax checking. 10236 1.1 jruoho 7. Compiler checks for duplicate ACPI name declarations 10237 1.1 jruoho 10238 1.1 jruoho Version X2012: 10239 1.1 jruoho 1. Relaxed typechecking to allow interchangeability between 10240 1.1 jruoho strings, integers, and buffers. These types are now converted by 10241 1.1 jruoho the interpreter at runtime. 10242 1.1 jruoho 2. Compiler reports time taken by each internal subsystem in the 10243 1.1 jruoho debug output file. 10244 1.1 jruoho 10245 1.1 jruoho 10246 1.1 jruoho ------------------------------------------ 10247 1.1 jruoho Summary of changes for this label: 12_14_00 10248 1.1 jruoho 10249 1.1 jruoho ASL Compiler: 10250 1.1 jruoho 10251 1.1 jruoho This is the first official release of the compiler. Since the 10252 1.1 jruoho compiler requires elements of the Core Subsystem, this label 10253 1.1 jruoho synchronizes everything. 10254 1.1 jruoho 10255 1.1 jruoho ------------------------------------------ 10256 1.1 jruoho Summary of changes for this label: 12_08_00 10257 1.1 jruoho 10258 1.1 jruoho 10259 1.1 jruoho Fixed a problem where named references within the ASL definition 10260 1.1 jruoho of both OperationRegions and CreateXXXFields did not work 10261 1.1 jruoho properly. The symptom was an AE_AML_OPERAND_TYPE during 10262 1.1 jruoho initialization of the region/field. This is similar (but not 10263 1.1 jruoho related internally) to the problem that was fixed in the last 10264 1.1 jruoho label. 10265 1.1 jruoho 10266 1.1 jruoho Implemented both 32-bit and 64-bit support for the BCD ASL 10267 1.1 jruoho functions ToBCD and FromBCD. 10268 1.1 jruoho 10269 1.1 jruoho Updated all legal headers to include "2000" in the copyright 10270 1.1 jruoho years. 10271 1.1 jruoho 10272 1.1 jruoho ------------------------------------------ 10273 1.1 jruoho Summary of changes for this label: 12_01_00 10274 1.1 jruoho 10275 1.1 jruoho Fixed a problem where method invocations within the ASL definition 10276 1.1 jruoho of both OperationRegions and CreateXXXFields did not work 10277 1.1 jruoho properly. The symptom was an AE_AML_OPERAND_TYPE during 10278 1.1 jruoho initialization of the region/field: 10279 1.1 jruoho 10280 1.1 jruoho nsinit-0209: AE_AML_OPERAND_TYPE while getting region arguments 10281 1.1 jruoho [DEBG] ammonad-0284: Exec_monadic2_r/Not: bad operand(s) 10282 1.1 jruoho (0x3005) 10283 1.1 jruoho 10284 1.1 jruoho Fixed a problem where operators with more than one nested 10285 1.1 jruoho subexpression would fail. The symptoms were varied, by mostly 10286 1.1 jruoho AE_AML_OPERAND_TYPE errors. This was actually a rather serious 10287 1.1 jruoho problem that has gone unnoticed until now. 10288 1.1 jruoho 10289 1.1 jruoho Subtract (Add (1,2), Multiply (3,4)) 10290 1.1 jruoho 10291 1.1 jruoho Fixed a problem where AcpiGetHandle didn't quite get fixed in the 10292 1.1 jruoho previous build (The prefix part of a relative path was handled 10293 1.1 jruoho incorrectly). 10294 1.1 jruoho 10295 1.1 jruoho Fixed a problem where Operation Region initialization failed if 10296 1.1 jruoho the operation region name was a "namepath" instead of a simple 10297 1.1 jruoho "nameseg". Symptom was an AE_NO_OPERAND error. 10298 1.1 jruoho 10299 1.1 jruoho Fixed a problem where an assignment to a local variable via the 10300 1.1 jruoho indirect RefOf mechanism only worked for the first such 10301 1.1 jruoho assignment. Subsequent assignments were ignored. 10302 1.1 jruoho 10303 1.1 jruoho ------------------------------------------ 10304 1.1 jruoho Summary of changes for this label: 11_15_00 10305 1.1 jruoho 10306 1.1 jruoho ACPI 2.0 table support with backwards support for ACPI 1.0 and the 10307 1.1 jruoho 0.71 extensions. Note: although we can read ACPI 2.0 BIOS tables, 10308 1.1 jruoho the AML interpreter does NOT have support for the new 2.0 ASL 10309 1.1 jruoho grammar terms at this time. 10310 1.1 jruoho 10311 1.1 jruoho All ACPI hardware access is via the GAS structures in the ACPI 2.0 10312 1.1 jruoho FADT. 10313 1.1 jruoho 10314 1.1 jruoho All physical memory addresses across all platforms are now 64 bits 10315 1.1 jruoho wide. Logical address width remains dependent on the platform 10316 1.1 jruoho (i.e., "void *"). 10317 1.1 jruoho 10318 1.1 jruoho AcpiOsMapMemory interface changed to a 64-bit physical address. 10319 1.1 jruoho 10320 1.1 jruoho The AML interpreter integer size is now 64 bits, as per the ACPI 10321 1.1 jruoho 2.0 specification. 10322 1.1 jruoho 10323 1.1 jruoho For backwards compatibility with ACPI 1.0, ACPI tables with a 10324 1.1 jruoho revision number less than 2 use 32-bit integers only. 10325 1.1 jruoho 10326 1.1 jruoho Fixed a problem where the evaluation of OpRegion operands did not 10327 1.1 jruoho always resolve them to numbers properly. 10328 1.1 jruoho 10329 1.1 jruoho ------------------------------------------ 10330 1.1 jruoho Summary of changes for this label: 10_20_00 10331 1.1 jruoho 10332 1.1 jruoho Fix for CBN_._STA issue. This fix will allow correct access to 10333 1.1 jruoho CBN_ OpRegions when the _STA returns 0x8. 10334 1.1 jruoho 10335 1.1 jruoho Support to convert ACPI constants (Ones, Zeros, One) to actual 10336 1.1 jruoho values before a package object is returned 10337 1.1 jruoho 10338 1.1 jruoho Fix for method call as predicate to if/while construct causing 10339 1.1 jruoho incorrect if/while behavior 10340 1.1 jruoho 10341 1.1 jruoho Fix for Else block package lengths sometimes calculated wrong (if 10342 1.1 jruoho block > 63 bytes) 10343 1.1 jruoho 10344 1.1 jruoho Fix for Processor object length field, was always zero 10345 1.1 jruoho 10346 1.1 jruoho Table load abort if FACP sanity check fails 10347 1.1 jruoho 10348 1.1 jruoho Fix for problem with Scope(name) if name already exists 10349 1.1 jruoho 10350 1.1 jruoho Warning emitted if a named object referenced cannot be found 10351 1.1 jruoho (resolved) during method execution. 10352 1.1 jruoho 10353 1.1 jruoho 10354 1.1 jruoho 10355 1.1 jruoho 10356 1.1 jruoho 10357 1.1 jruoho ------------------------------------------ 10358 1.1 jruoho Summary of changes for this label: 9_29_00 10359 1.1 jruoho 10360 1.1 jruoho New table initialization interfaces: AcpiInitializeSubsystem no 10361 1.1 jruoho longer has any parameters AcpiFindRootPointer - Find the RSDP (if 10362 1.1 jruoho necessary) AcpiLoadTables (RSDP) - load all tables found at RSDP- 10363 1.1 jruoho >RSDT Obsolete Interfaces AcpiLoadFirmwareTables - replaced by 10364 1.1 jruoho AcpiLoadTables 10365 1.1 jruoho 10366 1.1 jruoho Note: These interface changes require changes to all existing OSDs 10367 1.1 jruoho 10368 1.1 jruoho The PCI_Config default address space handler is always installed 10369 1.1 jruoho at the root namespace object. 10370 1.1 jruoho 10371 1.1 jruoho ------------------------------------------- 10372 1.1 jruoho Summary of changes for this label: 09_15_00 10373 1.1 jruoho 10374 1.1 jruoho The new initialization architecture is implemented. New 10375 1.1 jruoho interfaces are: AcpiInitializeSubsystem (replaces AcpiInitialize) 10376 1.1 jruoho AcpiEnableSubsystem Obsolete Interfaces: AcpiLoadNamespace 10377 1.1 jruoho 10378 1.1 jruoho (Namespace is automatically loaded when a table is loaded) 10379 1.1 jruoho 10380 1.1 jruoho The ACPI_OPERAND_OBJECT has been optimized to shrink its size from 10381 1.1 jruoho 52 bytes to 32 bytes. There is usually one of these for every 10382 1.1 jruoho namespace object, so the memory savings is significant. 10383 1.1 jruoho 10384 1.1 jruoho Implemented just-in-time evaluation of the CreateField operators. 10385 1.1 jruoho 10386 1.1 jruoho Bug fixes for IA-64 support have been integrated. 10387 1.1 jruoho 10388 1.1 jruoho Additional code review comments have been implemented 10389 1.1 jruoho 10390 1.1 jruoho The so-called "third pass parse" has been replaced by a final walk 10391 1.1 jruoho through the namespace to initialize all operation regions (address 10392 1.1 jruoho spaces) and fields that have not yet been initialized during the 10393 1.1 jruoho execution of the various _INI and REG methods. 10394 1.1 jruoho 10395 1.1 jruoho New file - namespace/nsinit.c 10396 1.1 jruoho 10397 1.1 jruoho ------------------------------------------- 10398 1.1 jruoho Summary of changes for this label: 09_01_00 10399 1.1 jruoho 10400 1.1 jruoho Namespace manager data structures have been reworked to change the 10401 1.1 jruoho primary object from a table to a single object. This has 10402 1.1 jruoho resulted in dynamic memory savings of 3X within the namespace and 10403 1.1 jruoho 2X overall in the ACPI CA subsystem. 10404 1.1 jruoho 10405 1.1 jruoho Fixed problem where the call to AcpiEvFindPciRootBuses was 10406 1.1 jruoho inadvertently left commented out. 10407 1.1 jruoho 10408 1.1 jruoho Reduced the warning count when generating the source with the GCC 10409 1.1 jruoho compiler. 10410 1.1 jruoho 10411 1.1 jruoho Revision numbers added to each module header showing the 10412 1.1 jruoho SourceSafe version of the file. Please refer to this version 10413 1.1 jruoho number when giving us feedback or comments on individual modules. 10414 1.1 jruoho 10415 1.1 jruoho The main object types within the subsystem have been renamed to 10416 1.1 jruoho clarify their purpose: 10417 1.1 jruoho 10418 1.1 jruoho ACPI_INTERNAL_OBJECT -> ACPI_OPERAND_OBJECT 10419 1.1 jruoho ACPI_GENERIC_OP -> ACPI_PARSE_OBJECT 10420 1.1 jruoho ACPI_NAME_TABLE_ENTRY -> ACPI_NAMESPACE_NODE 10421 1.1 jruoho 10422 1.1 jruoho NOTE: no changes to the initialization sequence are included in 10423 1.1 jruoho this label. 10424 1.1 jruoho 10425 1.1 jruoho ------------------------------------------- 10426 1.1 jruoho Summary of changes for this label: 08_23_00 10427 1.1 jruoho 10428 1.1 jruoho Fixed problem where TerminateControlMethod was being called 10429 1.1 jruoho multiple times per method 10430 1.1 jruoho 10431 1.1 jruoho Fixed debugger problem where single stepping caused a semaphore to 10432 1.1 jruoho be oversignalled 10433 1.1 jruoho 10434 1.1 jruoho Improved performance through additional parse object caching - 10435 1.1 jruoho added ACPI_EXTENDED_OP type 10436 1.1 jruoho 10437 1.1 jruoho ------------------------------------------- 10438 1.1 jruoho Summary of changes for this label: 08_10_00 10439 1.1 jruoho 10440 1.1 jruoho Parser/Interpreter integration: Eliminated the creation of 10441 1.1 jruoho complete parse trees for ACPI tables and control methods. 10442 1.1 jruoho Instead, parse subtrees are created and then deleted as soon as 10443 1.1 jruoho they are processed (Either entered into the namespace or executed 10444 1.1 jruoho by the interpreter). This reduces the use of dynamic kernel 10445 1.1 jruoho memory significantly. (about 10X) 10446 1.1 jruoho 10447 1.1 jruoho Exception codes broken into classes and renumbered. Be sure to 10448 1.1 jruoho recompile all code that includes acexcep.h. Hopefully we won't 10449 1.1 jruoho have to renumber the codes again now that they are split into 10450 1.1 jruoho classes (environment, programmer, AML code, ACPI table, and 10451 1.1 jruoho internal). 10452 1.1 jruoho 10453 1.1 jruoho Fixed some additional alignment issues in the Resource Manager 10454 1.1 jruoho subcomponent 10455 1.1 jruoho 10456 1.1 jruoho Implemented semaphore tracking in the AcpiExec utility, and fixed 10457 1.1 jruoho several places where mutexes/semaphores were being unlocked 10458 1.1 jruoho without a corresponding lock operation. There are no known 10459 1.1 jruoho semaphore or mutex "leaks" at this time. 10460 1.1 jruoho 10461 1.1 jruoho Fixed the case where an ASL Return operator is used to return an 10462 1.1 jruoho unnamed package. 10463 1.1 jruoho 10464 1.1 jruoho ------------------------------------------- 10465 1.1 jruoho Summary of changes for this label: 07_28_00 10466 1.1 jruoho 10467 1.1 jruoho Fixed a problem with the way addresses were calculated in 10468 1.1 jruoho AcpiAmlReadFieldData() and AcpiAmlWriteFieldData(). This problem 10469 1.1 jruoho manifested itself when a Field was created with WordAccess or 10470 1.1 jruoho DwordAccess, but the field unit defined within the Field was less 10471 1.1 jruoho 10472 1.1 jruoho than a Word or Dword. 10473 1.1 jruoho 10474 1.1 jruoho Fixed a problem in AmlDumpOperands() module's loop to pull 10475 1.1 jruoho operands off of the operand stack to display information. The 10476 1.1 jruoho problem manifested itself as a TLB error on 64-bit systems when 10477 1.1 jruoho accessing an operand stack with two or more operands. 10478 1.1 jruoho 10479 1.1 jruoho Fixed a problem with the PCI configuration space handlers where 10480 1.1 jruoho context was getting confused between accesses. This required a 10481 1.1 jruoho change to the generic address space handler and address space 10482 1.1 jruoho setup definitions. Handlers now get both a global handler context 10483 1.1 jruoho (this is the one passed in by the user when executing 10484 1.1 jruoho AcpiInstallAddressSpaceHandler() and a specific region context 10485 1.1 jruoho that is unique to each region (For example, the _ADR, _SEG and 10486 1.1 jruoho _BBN values associated with a specific region). The generic 10487 1.1 jruoho function definitions have changed to the following: 10488 1.1 jruoho 10489 1.1 jruoho typedef ACPI_STATUS (*ADDRESS_SPACE_HANDLER) ( UINT32 Function, 10490 1.1 jruoho UINT32 Address, UINT32 BitWidth, UINT32 *Value, void 10491 1.1 jruoho *HandlerContext, // This used to be void *Context void 10492 1.1 jruoho *RegionContext); // This is an additional parameter 10493 1.1 jruoho 10494 1.1 jruoho typedef ACPI_STATUS (*ADDRESS_SPACE_SETUP) ( ACPI_HANDLE 10495 1.1 jruoho RegionHandle, UINT32 Function, void *HandlerContext, void 10496 1.1 jruoho **RegionContext); // This used to be **ReturnContext 10497 1.1 jruoho 10498 1.1 jruoho ------------------------------------------- 10499 1.1 jruoho Summary of changes for this label: 07_21_00 10500 1.1 jruoho 10501 1.1 jruoho Major file consolidation and rename. All files within the 10502 1.1 jruoho interpreter have been renamed as well as most header files. This 10503 1.1 jruoho was done to prevent collisions with existing files in the host 10504 1.1 jruoho OSs -- filenames such as "config.h" and "global.h" seem to be 10505 1.1 jruoho quite common. The VC project files have been updated. All 10506 1.1 jruoho makefiles will require modification. 10507 1.1 jruoho 10508 1.1 jruoho The parser/interpreter integration continues in Phase 5 with the 10509 1.1 jruoho implementation of a complete 2-pass parse (the AML is parsed 10510 1.1 jruoho twice) for each table; This avoids the construction of a huge 10511 1.1 jruoho parse tree and therefore reduces the amount of dynamic memory 10512 1.1 jruoho required by the subsystem. Greater use of the parse object cache 10513 1.1 jruoho means that performance is unaffected. 10514 1.1 jruoho 10515 1.1 jruoho Many comments from the two code reviews have been rolled in. 10516 1.1 jruoho 10517 1.1 jruoho The 64-bit alignment support is complete. 10518 1.1 jruoho 10519 1.1 jruoho ------------------------------------------- 10520 1.1 jruoho Summary of changes for this label: 06_30_00 10521 1.1 jruoho 10522 1.1 jruoho With a nod and a tip of the hat to the technology of yesteryear, 10523 1.1 jruoho we've added support in the source code for 80 column output 10524 1.1 jruoho devices. The code is now mostly constrained to 80 columns or 10525 1.1 jruoho less to support environments and editors that 1) cannot display 10526 1.1 jruoho or print more than 80 characters on a single line, and 2) cannot 10527 1.1 jruoho disable line wrapping. 10528 1.1 jruoho 10529 1.1 jruoho A major restructuring of the namespace data structure has been 10530 1.1 jruoho completed. The result is 1) cleaner and more 10531 1.1 jruoho understandable/maintainable code, and 2) a significant reduction 10532 1.1 jruoho in the dynamic memory requirement for each named ACPI object 10533 1.1 jruoho (almost half). 10534 1.1 jruoho 10535 1.1 jruoho ------------------------------------------- 10536 1.1 jruoho Summary of changes for this label: 06_23_00 10537 1.1 jruoho 10538 1.1 jruoho Linux support has been added. In order to obtain approval to get 10539 1.1 jruoho the ACPI CA subsystem into the Linux kernel, we've had to make 10540 1.1 jruoho quite a few changes to the base subsystem that will affect all 10541 1.1 jruoho users (all the changes are generic and OS- independent). The 10542 1.1 jruoho effects of these global changes have been somewhat far reaching. 10543 1.1 jruoho Files have been merged and/or renamed and interfaces have been 10544 1.1 jruoho renamed. The major changes are described below. 10545 1.1 jruoho 10546 1.1 jruoho Osd* interfaces renamed to AcpiOs* to eliminate namespace 10547 1.1 jruoho pollution/confusion within our target kernels. All OSD 10548 1.1 jruoho interfaces must be modified to match the new naming convention. 10549 1.1 jruoho 10550 1.1 jruoho Files merged across the subsystem. A number of the smaller source 10551 1.1 jruoho and header files have been merged to reduce the file count and 10552 1.1 jruoho increase the density of the existing files. There are too many 10553 1.1 jruoho to list here. In general, makefiles that call out individual 10554 1.1 jruoho files will require rebuilding. 10555 1.1 jruoho 10556 1.1 jruoho Interpreter files renamed. All interpreter files now have the 10557 1.1 jruoho prefix am* instead of ie* and is*. 10558 1.1 jruoho 10559 1.1 jruoho Header files renamed: The acapi.h file is now acpixf.h. The 10560 1.1 jruoho acpiosd.h file is now acpiosxf.h. We are removing references to 10561 1.1 jruoho the acronym "API" since it is somewhat windowsy. The new name is 10562 1.1 jruoho "external interface" or xface or xf in the filenames.j 10563 1.1 jruoho 10564 1.1 jruoho 10565 1.1 jruoho All manifest constants have been forced to upper case (some were 10566 1.1 jruoho mixed case.) Also, the string "ACPI_" has been prepended to many 10567 1.1 jruoho (not all) of the constants, typedefs, and structs. 10568 1.1 jruoho 10569 1.1 jruoho The globals "DebugLevel" and "DebugLayer" have been renamed 10570 1.1 jruoho "AcpiDbgLevel" and "AcpiDbgLayer" respectively. 10571 1.1 jruoho 10572 1.1 jruoho All other globals within the subsystem are now prefixed with 10573 1.1 jruoho "AcpiGbl_" Internal procedures within the subsystem are now 10574 1.1 jruoho prefixed with "Acpi" (with only a few exceptions). The original 10575 1.1 jruoho two-letter abbreviation for the subcomponent remains after "Acpi" 10576 1.1 jruoho - for example, CmCallocate became AcpiCmCallocate. 10577 1.1 jruoho 10578 1.1 jruoho Added a source code translation/conversion utility. Used to 10579 1.1 jruoho generate the Linux source code, it can be modified to generate 10580 1.1 jruoho other types of source as well. Can also be used to cleanup 10581 1.1 jruoho existing source by removing extraneous spaces and blank lines. 10582 1.1 jruoho Found in tools/acpisrc/* 10583 1.1 jruoho 10584 1.1 jruoho OsdUnMapMemory was renamed to OsdUnmapMemory and then 10585 1.1 jruoho AcpiOsUnmapMemory. (UnMap became Unmap). 10586 1.1 jruoho 10587 1.1 jruoho A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore. 10588 1.1 jruoho When set to one, this indicates that the caller wants to use the 10589 1.1 jruoho 10590 1.1 jruoho semaphore as a mutex, not a counting semaphore. ACPI CA uses 10591 1.1 jruoho both types. However, implementers of this call may want to use 10592 1.1 jruoho different OS primitives depending on the type of semaphore 10593 1.1 jruoho requested. For example, some operating systems provide separate 10594 1.1 jruoho 10595 1.1 jruoho "mutex" and "semaphore" interfaces - where the mutex interface is 10596 1.1 jruoho much faster because it doesn't have all the overhead of a full 10597 1.1 jruoho semaphore implementation. 10598 1.1 jruoho 10599 1.1 jruoho Fixed a deadlock problem where a method that accesses the PCI 10600 1.1 jruoho address space can block forever if it is the first access to the 10601 1.1 jruoho space. 10602 1.1 jruoho 10603 1.1 jruoho ------------------------------------------- 10604 1.1 jruoho Summary of changes for this label: 06_02_00 10605 1.1 jruoho 10606 1.1 jruoho Support for environments that cannot handle unaligned data 10607 1.1 jruoho accesses (e.g. firmware and OS environments devoid of alignment 10608 1.1 jruoho handler technology namely SAL/EFI and the IA-64 Linux kernel) has 10609 1.1 jruoho been added (via configurable macros) in these three areas: - 10610 1.1 jruoho Transfer of data from the raw AML byte stream is done via byte 10611 1.1 jruoho moves instead of word/dword/qword moves. - External objects are 10612 1.1 jruoho aligned within the user buffer, including package elements (sub- 10613 1.1 jruoho objects). - Conversion of name strings to UINT32 Acpi Names is now 10614 1.1 jruoho done byte-wise. 10615 1.1 jruoho 10616 1.1 jruoho The Store operator was modified to mimic Microsoft's 10617 1.1 jruoho implementation when storing to a Buffer Field. 10618 1.1 jruoho 10619 1.1 jruoho Added a check of the BM_STS bit before entering C3. 10620 1.1 jruoho 10621 1.1 jruoho The methods subdirectory has been obsoleted and removed. A new 10622 1.1 jruoho file, cmeval.c subsumes the functionality. 10623 1.1 jruoho 10624 1.1 jruoho A 16-bit (DOS) version of AcpiExec has been developed. The 10625 1.1 jruoho makefile is under the acpiexec directory. 10626
