1 1.1.1.2.2.2 bouyer ---------------------------------------- 2 1.1.1.2.2.2 bouyer 11 February 2011. Summary of changes for version 20110211: 3 1.1.1.2.2.2 bouyer 4 1.1.1.2.2.2 bouyer This release is available at www.acpica.org/downloads 5 1.1.1.2.2.2 bouyer 6 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 7 1.1.1.2.2.2 bouyer 8 1.1.1.2.2.2 bouyer Added a mechanism to defer _REG methods for some early-installed handlers. 9 1.1.1.2.2.2 bouyer Most user handlers should be installed before call to AcpiEnableSubsystem. 10 1.1.1.2.2.2 bouyer However, Event handlers and region handlers should be installed after 11 1.1.1.2.2.2 bouyer AcpiInitializeObjects. Override handlers for the "default" regions should be 12 1.1.1.2.2.2 bouyer installed early, however. This change executes all _REG methods for the 13 1.1.1.2.2.2 bouyer default regions (Memory/IO/PCI/DataTable) simultaneously to prevent any 14 1.1.1.2.2.2 bouyer chicken/egg issues between them. ACPICA BZ 848. 15 1.1.1.2.2.2 bouyer 16 1.1.1.2.2.2 bouyer Implemented an optimization for GPE detection. This optimization will simply 17 1.1.1.2.2.2 bouyer ignore GPE registers that contain no enabled GPEs -- there is no need to 18 1.1.1.2.2.2 bouyer read the register since this information is available internally. This 19 1.1.1.2.2.2 bouyer becomes more important on machines with a large GPE space. ACPICA bugzilla 20 1.1.1.2.2.2 bouyer 884. Lin Ming. Suggestion from Joe Liu. 21 1.1.1.2.2.2 bouyer 22 1.1.1.2.2.2 bouyer Removed all use of the highly unreliable FADT revision field. The revision 23 1.1.1.2.2.2 bouyer number in the FADT has been found to be completely unreliable and cannot be 24 1.1.1.2.2.2 bouyer trusted. Only the actual table length can be used to infer the version. This 25 1.1.1.2.2.2 bouyer change updates the ACPICA core and the disassembler so that both no longer 26 1.1.1.2.2.2 bouyer even look at the FADT version and instead depend solely upon the FADT 27 1.1.1.2.2.2 bouyer length. 28 1.1.1.2.2.2 bouyer 29 1.1.1.2.2.2 bouyer Fix an unresolved name issue for the no-debug and no-error-message source 30 1.1.1.2.2.2 bouyer generation cases. The _AcpiModuleName was left undefined in these cases, but 31 1.1.1.2.2.2 bouyer it is actually needed as a parameter to some interfaces. Define 32 1.1.1.2.2.2 bouyer _AcpiModuleName as a null string in these cases. ACPICA Bugzilla 888. 33 1.1.1.2.2.2 bouyer 34 1.1.1.2.2.2 bouyer Split several large files (makefiles and project files updated) 35 1.1.1.2.2.2 bouyer utglobal.c -> utdecode.c 36 1.1.1.2.2.2 bouyer dbcomds.c -> dbmethod.c dbnames.c 37 1.1.1.2.2.2 bouyer dsopcode.c -> dsargs.c dscontrol.c 38 1.1.1.2.2.2 bouyer dsload.c -> dsload2.c 39 1.1.1.2.2.2 bouyer aslanalyze.c -> aslbtypes.c aslwalks.c 40 1.1.1.2.2.2 bouyer 41 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 42 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 43 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 44 1.1.1.2.2.2 bouyer a much larger code and data size. 45 1.1.1.2.2.2 bouyer 46 1.1.1.2.2.2 bouyer Previous Release (VC 9.0): 47 1.1.1.2.2.2 bouyer Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 48 1.1.1.2.2.2 bouyer Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 49 1.1.1.2.2.2 bouyer Current Release (VC 9.0): 50 1.1.1.2.2.2 bouyer Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 51 1.1.1.2.2.2 bouyer Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 52 1.1.1.2.2.2 bouyer 53 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 54 1.1.1.2.2.2 bouyer 55 1.1.1.2.2.2 bouyer iASL: Implemented the predefined macros __LINE__, __FILE__, and __DATE__. 56 1.1.1.2.2.2 bouyer These are useful C-style macros with the standard definitions. ACPICA 57 1.1.1.2.2.2 bouyer bugzilla 898. 58 1.1.1.2.2.2 bouyer 59 1.1.1.2.2.2 bouyer iASL/DTC: Added support for integer expressions and labels. Support for full 60 1.1.1.2.2.2 bouyer expressions for all integer fields in all ACPI tables. Support for labels in 61 1.1.1.2.2.2 bouyer "generic" portions of tables such as UEFI. See the iASL reference manual. 62 1.1.1.2.2.2 bouyer 63 1.1.1.2.2.2 bouyer Debugger: Added a command to display the status of global handlers. The 64 1.1.1.2.2.2 bouyer "handlers" command will display op region, fixed event, and miscellaneous 65 1.1.1.2.2.2 bouyer global handlers. installation status -- and for op regions, whether default 66 1.1.1.2.2.2 bouyer or user-installed handler will be used. 67 1.1.1.2.2.2 bouyer 68 1.1.1.2.2.2 bouyer iASL: Warn if reserved method incorrectly returns a value. Many predefined 69 1.1.1.2.2.2 bouyer names are defined such that they do not return a value. If implemented as a 70 1.1.1.2.2.2 bouyer method, issue a warning if such a name explicitly returns a value. ACPICA 71 1.1.1.2.2.2 bouyer Bugzilla 855. 72 1.1.1.2.2.2 bouyer 73 1.1.1.2.2.2 bouyer iASL: Added detection of GPE method name conflicts. Detects a conflict where 74 1.1.1.2.2.2 bouyer there are two GPE methods of the form _Lxy and _Exy in the same scope. (For 75 1.1.1.2.2.2 bouyer example, _L1D and _E1D in the same scope.) ACPICA bugzilla 848. 76 1.1.1.2.2.2 bouyer 77 1.1.1.2.2.2 bouyer iASL/DTC: Fixed a couple input scanner issues with comments and line 78 1.1.1.2.2.2 bouyer numbers. Comment remover could get confused and miss a comment ending. Fixed 79 1.1.1.2.2.2 bouyer a problem with line counter maintenance. 80 1.1.1.2.2.2 bouyer 81 1.1.1.2.2.2 bouyer iASL/DTC: Reduced the severity of some errors from fatal to error. There is 82 1.1.1.2.2.2 bouyer no need to abort on simple errors within a field definition. 83 1.1.1.2.2.2 bouyer 84 1.1.1.2.2.2 bouyer Debugger: Simplified the output of the help command. All help output now in 85 1.1.1.2.2.2 bouyer a single screen, instead of help subcommands. ACPICA Bugzilla 897. 86 1.1.1.2.2.2 bouyer 87 1.1.1.2.2.2 bouyer 88 1.1.1.2.2.2 bouyer ---------------------------------------- 89 1.1.1.2.2.2 bouyer 12 January 2011. Summary of changes for version 20110112: 90 1.1.1.2.2.2 bouyer 91 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 92 1.1.1.2.2.2 bouyer 93 1.1.1.2.2.2 bouyer Fixed a race condition between method execution and namespace walks that can 94 1.1.1.2.2.2 bouyer possibly cause a fault. The problem was apparently introduced in version 95 1.1.1.2.2.2 bouyer 20100528 as a result of a performance optimization that reduces the number 96 1.1.1.2.2.2 bouyer of 97 1.1.1.2.2.2 bouyer namespace walks upon method exit by using the delete_namespace_subtree 98 1.1.1.2.2.2 bouyer function instead of the delete_namespace_by_owner function used previously. 99 1.1.1.2.2.2 bouyer Bug is a missing namespace lock in the delete_namespace_subtree function. 100 1.1.1.2.2.2 bouyer dana.myers (a] oracle.com 101 1.1.1.2.2.2 bouyer 102 1.1.1.2.2.2 bouyer Fixed several issues and a possible fault with the automatic "serialized" 103 1.1.1.2.2.2 bouyer method support. History: This support changes a method to "serialized" on 104 1.1.1.2.2.2 bouyer the 105 1.1.1.2.2.2 bouyer fly if the method generates an AE_ALREADY_EXISTS error, indicating the 106 1.1.1.2.2.2 bouyer possibility that it cannot handle reentrancy. This fix repairs a couple of 107 1.1.1.2.2.2 bouyer issues seen in the field, especially on machines with many cores: 108 1.1.1.2.2.2 bouyer 109 1.1.1.2.2.2 bouyer 1) Delete method children only upon the exit of the last thread, 110 1.1.1.2.2.2 bouyer so as to not delete objects out from under other running threads 111 1.1.1.2.2.2 bouyer (and possibly causing a fault.) 112 1.1.1.2.2.2 bouyer 2) Set the "serialized" bit for the method only upon the exit of the 113 1.1.1.2.2.2 bouyer Last thread, so as to not cause deadlock when running threads 114 1.1.1.2.2.2 bouyer attempt to exit. 115 1.1.1.2.2.2 bouyer 3) Cleanup the use of the AML "MethodFlags" and internal method flags 116 1.1.1.2.2.2 bouyer so that there is no longer any confusion between the two. 117 1.1.1.2.2.2 bouyer 118 1.1.1.2.2.2 bouyer Lin Ming, Bob Moore. Reported by dana.myers (a] oracle.com. 119 1.1.1.2.2.2 bouyer 120 1.1.1.2.2.2 bouyer Debugger: Now lock the namespace for duration of a namespace dump. Prevents 121 1.1.1.2.2.2 bouyer issues if the namespace is changing dynamically underneath the debugger. 122 1.1.1.2.2.2 bouyer Especially affects temporary namespace nodes, since the debugger displays 123 1.1.1.2.2.2 bouyer these also. 124 1.1.1.2.2.2 bouyer 125 1.1.1.2.2.2 bouyer Updated the ordering of include files. The ACPICA headers should appear 126 1.1.1.2.2.2 bouyer before any compiler-specific headers (stdio.h, etc.) so that acenv.h can set 127 1.1.1.2.2.2 bouyer any necessary compiler-specific defines, etc. Affects the ACPI-related tools 128 1.1.1.2.2.2 bouyer and utilities. 129 1.1.1.2.2.2 bouyer 130 1.1.1.2.2.2 bouyer Updated all ACPICA copyrights and signons to 2011. Added the 2011 copyright 131 1.1.1.2.2.2 bouyer to all module headers and signons, including the Linux header. This affects 132 1.1.1.2.2.2 bouyer virtually every file in the ACPICA core subsystem, iASL compiler, and all 133 1.1.1.2.2.2 bouyer utilities. 134 1.1.1.2.2.2 bouyer 135 1.1.1.2.2.2 bouyer Added project files for MS Visual Studio 2008 (VC++ 9.0). The original 136 1.1.1.2.2.2 bouyer project files for VC++ 6.0 are now obsolete. New project files can be found 137 1.1.1.2.2.2 bouyer under acpica/generate/msvc9. See acpica/generate/msvc9/readme.txt for 138 1.1.1.2.2.2 bouyer details. 139 1.1.1.2.2.2 bouyer 140 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 141 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The 142 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 143 1.1.1.2.2.2 bouyer a 144 1.1.1.2.2.2 bouyer much larger code and data size. 145 1.1.1.2.2.2 bouyer 146 1.1.1.2.2.2 bouyer Previous Release (VC 6.0): 147 1.1.1.2.2.2 bouyer Non-Debug Version: 89.8K Code, 18.9K Data, 108.7K Total 148 1.1.1.2.2.2 bouyer Debug Version: 166.6K Code, 52.1K Data, 218.7K Total 149 1.1.1.2.2.2 bouyer Current Release (VC 9.0): 150 1.1.1.2.2.2 bouyer Non-Debug Version: 89.7K Code, 23.7K Data, 113.4K Total 151 1.1.1.2.2.2 bouyer Debug Version: 163.9K Code, 67.5K Data, 231.4K Total 152 1.1.1.2.2.2 bouyer 153 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 154 1.1.1.2.2.2 bouyer 155 1.1.1.2.2.2 bouyer iASL: Added generic data types to the Data Table compiler. Add "generic" 156 1.1.1.2.2.2 bouyer data 157 1.1.1.2.2.2 bouyer types such as UINT32, String, Unicode, etc., to simplify the generation of 158 1.1.1.2.2.2 bouyer platform-defined tables such as UEFI. Lin Ming. 159 1.1.1.2.2.2 bouyer 160 1.1.1.2.2.2 bouyer iASL: Added listing support for the Data Table Compiler. Adds listing 161 1.1.1.2.2.2 bouyer support 162 1.1.1.2.2.2 bouyer (-l) to display actual binary output for each line of input code. 163 1.1.1.2.2.2 bouyer 164 1.1.1.2.2.2 bouyer ---------------------------------------- 165 1.1.1.2.2.2 bouyer 09 December 2010. Summary of changes for version 20101209: 166 1.1.1.2.2.2 bouyer 167 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 168 1.1.1.2.2.2 bouyer 169 1.1.1.2.2.2 bouyer Completed the major overhaul of the GPE support code that was begun in July 170 1.1.1.2.2.2 bouyer 2010. Major features include: removal of _PRW execution in ACPICA (host 171 1.1.1.2.2.2 bouyer executes _PRWs anyway), cleanup of "wake" GPE interfaces and processing, 172 1.1.1.2.2.2 bouyer changes to existing interfaces, simplification of GPE handler operation, and 173 1.1.1.2.2.2 bouyer a handful of new interfaces: 174 1.1.1.2.2.2 bouyer 175 1.1.1.2.2.2 bouyer AcpiUpdateAllGpes 176 1.1.1.2.2.2 bouyer AcpiFinishGpe 177 1.1.1.2.2.2 bouyer AcpiSetupGpeForWake 178 1.1.1.2.2.2 bouyer AcpiSetGpeWakeMask 179 1.1.1.2.2.2 bouyer One new file, evxfgpe.c to consolidate all external GPE interfaces. 180 1.1.1.2.2.2 bouyer 181 1.1.1.2.2.2 bouyer See the ACPICA Programmer Reference for full details and programming 182 1.1.1.2.2.2 bouyer information. See the new section 4.4 "General Purpose Event (GPE) Support" 183 1.1.1.2.2.2 bouyer for a full overview, and section 8.7 "ACPI General Purpose Event Management" 184 1.1.1.2.2.2 bouyer for programming details. ACPICA BZ 858,870,877. Matthew Garrett, Lin Ming, 185 1.1.1.2.2.2 bouyer Bob Moore, Rafael Wysocki. 186 1.1.1.2.2.2 bouyer 187 1.1.1.2.2.2 bouyer Implemented a new GPE feature for Windows compatibility, the "Implicit Wake 188 1.1.1.2.2.2 bouyer GPE Notify". This feature will automatically issue a Notify(2) on a device 189 1.1.1.2.2.2 bouyer when a Wake GPE is received if there is no corresponding GPE method or 190 1.1.1.2.2.2 bouyer handler. ACPICA BZ 870. 191 1.1.1.2.2.2 bouyer 192 1.1.1.2.2.2 bouyer Fixed a problem with the Scope() operator during table parse and load phase. 193 1.1.1.2.2.2 bouyer During load phase (table load or method execution), the scope operator 194 1.1.1.2.2.2 bouyer should 195 1.1.1.2.2.2 bouyer not enter the target into the namespace. Instead, it should open a new scope 196 1.1.1.2.2.2 bouyer at the target location. Linux BZ 19462, ACPICA BZ 882. 197 1.1.1.2.2.2 bouyer 198 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 199 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 200 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 201 1.1.1.2.2.2 bouyer a 202 1.1.1.2.2.2 bouyer much larger code and data size. 203 1.1.1.2.2.2 bouyer 204 1.1.1.2.2.2 bouyer Previous Release: 205 1.1.1.2.2.2 bouyer Non-Debug Version: 89.8K Code, 18.9K Data, 108.7K Total 206 1.1.1.2.2.2 bouyer Debug Version: 166.6K Code, 52.1K Data, 218.7K Total 207 1.1.1.2.2.2 bouyer Current Release: 208 1.1.1.2.2.2 bouyer Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 209 1.1.1.2.2.2 bouyer Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 210 1.1.1.2.2.2 bouyer 211 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 212 1.1.1.2.2.2 bouyer 213 1.1.1.2.2.2 bouyer iASL: Relax the alphanumeric restriction on _CID strings. These strings are 214 1.1.1.2.2.2 bouyer "bus-specific" per the ACPI specification, and therefore any characters are 215 1.1.1.2.2.2 bouyer acceptable. The only checks that can be performed are for a null string and 216 1.1.1.2.2.2 bouyer perhaps for a leading asterisk. ACPICA BZ 886. 217 1.1.1.2.2.2 bouyer 218 1.1.1.2.2.2 bouyer iASL: Fixed a problem where a syntax error that caused a premature EOF 219 1.1.1.2.2.2 bouyer condition on the source file emitted a very confusing error message. The 220 1.1.1.2.2.2 bouyer premature EOF is now detected correctly. ACPICA BZ 891. 221 1.1.1.2.2.2 bouyer 222 1.1.1.2.2.2 bouyer Disassembler: Decode the AccessSize within a Generic Address Structure (byte 223 1.1.1.2.2.2 bouyer access, word access, etc.) Note, this field does not allow arbitrary bit 224 1.1.1.2.2.2 bouyer access, the size is encoded as 1=byte, 2=word, 3=dword, and 4=qword. 225 1.1.1.2.2.2 bouyer 226 1.1.1.2.2.2 bouyer New: AcpiNames utility - Example namespace dump utility. Shows an example of 227 1.1.1.2.2.2 bouyer ACPICA configuration for a minimal namespace dump utility. Uses table and 228 1.1.1.2.2.2 bouyer namespace managers, but no AML interpreter. Does not add any functionality 229 1.1.1.2.2.2 bouyer over AcpiExec, it is a subset of AcpiExec. The purpose is to show how to 230 1.1.1.2.2.2 bouyer partition and configure ACPICA. ACPICA BZ 883. 231 1.1.1.2.2.2 bouyer 232 1.1.1.2.2.2 bouyer AML Debugger: Increased the debugger buffer size for method return objects. 233 1.1.1.2.2.2 bouyer Was 4K, increased to 16K. Also enhanced error messages for debugger method 234 1.1.1.2.2.2 bouyer execution, including the buffer overflow case. 235 1.1.1.2.2.2 bouyer 236 1.1.1.2.2.2 bouyer ---------------------------------------- 237 1.1.1.2.2.2 bouyer 13 October 2010. Summary of changes for version 20101013: 238 1.1.1.2.2.2 bouyer 239 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 240 1.1.1.2.2.2 bouyer 241 1.1.1.2.2.2 bouyer Added support to clear the PCIEXP_WAKE event. When clearing ACPI events, now 242 1.1.1.2.2.2 bouyer clear the PCIEXP_WAKE_STS bit in the ACPI PM1 Status Register, via 243 1.1.1.2.2.2 bouyer HwClearAcpiStatus. Original change from Colin King. ACPICA BZ 880. 244 1.1.1.2.2.2 bouyer 245 1.1.1.2.2.2 bouyer Changed the type of the predefined namespace object _TZ from ThermalZone to 246 1.1.1.2.2.2 bouyer Device. This was found to be confusing to the host software that processes 247 1.1.1.2.2.2 bouyer the various thermal zones, since _TZ is not really a ThermalZone. However, a 248 1.1.1.2.2.2 bouyer Notify() can still be performed on it. ACPICA BZ 876. Suggestion from Rui 249 1.1.1.2.2.2 bouyer Zhang. 250 1.1.1.2.2.2 bouyer 251 1.1.1.2.2.2 bouyer Added Windows Vista SP2 to the list of supported _OSI strings. The actual 252 1.1.1.2.2.2 bouyer string is "Windows 2006 SP2". 253 1.1.1.2.2.2 bouyer 254 1.1.1.2.2.2 bouyer Eliminated duplicate code in AcpiUtExecute* functions. Now that the nsrepair 255 1.1.1.2.2.2 bouyer code automatically repairs _HID-related strings, this type of code is no 256 1.1.1.2.2.2 bouyer longer needed in Execute_HID, Execute_CID, and Execute_UID. ACPICA BZ 878. 257 1.1.1.2.2.2 bouyer 258 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 259 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 260 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 261 1.1.1.2.2.2 bouyer a 262 1.1.1.2.2.2 bouyer much larger code and data size. 263 1.1.1.2.2.2 bouyer 264 1.1.1.2.2.2 bouyer Previous Release: 265 1.1.1.2.2.2 bouyer Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 266 1.1.1.2.2.2 bouyer Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 267 1.1.1.2.2.2 bouyer Current Release: 268 1.1.1.2.2.2 bouyer Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 269 1.1.1.2.2.2 bouyer Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 270 1.1.1.2.2.2 bouyer 271 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 272 1.1.1.2.2.2 bouyer 273 1.1.1.2.2.2 bouyer iASL: Implemented additional compile-time validation for _HID strings. The 274 1.1.1.2.2.2 bouyer non-hex prefix (such as "PNP" or "ACPI") must be uppercase, and the length 275 1.1.1.2.2.2 bouyer of 276 1.1.1.2.2.2 bouyer the string must be exactly seven or eight characters. For both _HID and _CID 277 1.1.1.2.2.2 bouyer strings, all characters must be alphanumeric. ACPICA BZ 874. 278 1.1.1.2.2.2 bouyer 279 1.1.1.2.2.2 bouyer iASL: Allow certain "null" resource descriptors. Some BIOS code creates 280 1.1.1.2.2.2 bouyer descriptors that are mostly or all zeros, with the expectation that they 281 1.1.1.2.2.2 bouyer will 282 1.1.1.2.2.2 bouyer be filled in at runtime. iASL now allows this as long as there is a 283 1.1.1.2.2.2 bouyer "resource 284 1.1.1.2.2.2 bouyer tag" (name) associated with the descriptor, which gives the ASL a handle 285 1.1.1.2.2.2 bouyer needed to modify the descriptor. ACPICA BZ 873. 286 1.1.1.2.2.2 bouyer 287 1.1.1.2.2.2 bouyer Added single-thread support to the generic Unix application OSL. Primarily 288 1.1.1.2.2.2 bouyer for iASL support, this change removes the use of semaphores in the single- 289 1.1.1.2.2.2 bouyer threaded ACPICA tools/applications - increasing performance. The 290 1.1.1.2.2.2 bouyer _MULTI_THREADED option was replaced by the (reverse) ACPI_SINGLE_THREADED 291 1.1.1.2.2.2 bouyer option. ACPICA BZ 879. 292 1.1.1.2.2.2 bouyer 293 1.1.1.2.2.2 bouyer AcpiExec: several fixes for the 64-bit version. Adds XSDT support and 294 1.1.1.2.2.2 bouyer support 295 1.1.1.2.2.2 bouyer for 64-bit DSDT/FACS addresses in the FADT. Lin Ming. 296 1.1.1.2.2.2 bouyer 297 1.1.1.2.2.2 bouyer iASL: Moved all compiler messages to a new file, aslmessages.h. 298 1.1.1.2.2.2 bouyer 299 1.1.1.2.2.2 bouyer ---------------------------------------- 300 1.1.1.2.2.2 bouyer 15 September 2010. Summary of changes for version 20100915: 301 1.1.1.2.2.2 bouyer 302 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 303 1.1.1.2.2.2 bouyer 304 1.1.1.2.2.2 bouyer Removed the AcpiOsDerivePciId OSL interface. The various host 305 1.1.1.2.2.2 bouyer implementations 306 1.1.1.2.2.2 bouyer of this function were not OS-dependent and are now obsolete and can be 307 1.1.1.2.2.2 bouyer removed from all host OSLs. This function has been replaced by 308 1.1.1.2.2.2 bouyer AcpiHwDerivePciId, which is now part of the ACPICA core code. 309 1.1.1.2.2.2 bouyer AcpiHwDerivePciId has been implemented without recursion. Adds one new 310 1.1.1.2.2.2 bouyer module, hwpci.c. ACPICA BZ 857. 311 1.1.1.2.2.2 bouyer 312 1.1.1.2.2.2 bouyer Implemented a dynamic repair for _HID and _CID strings. The following 313 1.1.1.2.2.2 bouyer problems are now repaired at runtime: 1) Remove a leading asterisk in the 314 1.1.1.2.2.2 bouyer string, and 2) the entire string is uppercased. Both repairs are in 315 1.1.1.2.2.2 bouyer accordance with the ACPI specification and will simplify host driver code. 316 1.1.1.2.2.2 bouyer ACPICA BZ 871. 317 1.1.1.2.2.2 bouyer 318 1.1.1.2.2.2 bouyer The ACPI_THREAD_ID type is no longer configurable, internally it is now 319 1.1.1.2.2.2 bouyer always UINT64. This simplifies the ACPICA code, especially any printf 320 1.1.1.2.2.2 bouyer output. 321 1.1.1.2.2.2 bouyer UINT64 is the only common data type for all thread_id types across all 322 1.1.1.2.2.2 bouyer operating systems. It is now up to the host OSL to cast the native thread_id 323 1.1.1.2.2.2 bouyer type to UINT64 before returning the value to ACPICA (via AcpiOsGetThreadId). 324 1.1.1.2.2.2 bouyer Lin Ming, Bob Moore. 325 1.1.1.2.2.2 bouyer 326 1.1.1.2.2.2 bouyer Added the ACPI_INLINE type to enhance the ACPICA configuration. The "inline" 327 1.1.1.2.2.2 bouyer keyword is not standard across compilers, and this type allows inline to be 328 1.1.1.2.2.2 bouyer configured on a per-compiler basis. Lin Ming. 329 1.1.1.2.2.2 bouyer 330 1.1.1.2.2.2 bouyer Made the system global AcpiGbl_SystemAwakeAndRunning publically available. 331 1.1.1.2.2.2 bouyer Added an extern for this boolean in acpixf.h. Some hosts utilize this value 332 1.1.1.2.2.2 bouyer during suspend/restore operations. ACPICA BZ 869. 333 1.1.1.2.2.2 bouyer 334 1.1.1.2.2.2 bouyer All code that implements error/warning messages with the "ACPI:" prefix has 335 1.1.1.2.2.2 bouyer been moved to a new module, utxferror.c. 336 1.1.1.2.2.2 bouyer 337 1.1.1.2.2.2 bouyer The UINT64_OVERLAY was moved to utmath.c, which is the only module where it 338 1.1.1.2.2.2 bouyer is used. ACPICA BZ 829. Lin Ming, Bob Moore. 339 1.1.1.2.2.2 bouyer 340 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 341 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 342 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 343 1.1.1.2.2.2 bouyer a 344 1.1.1.2.2.2 bouyer much larger code and data size. 345 1.1.1.2.2.2 bouyer 346 1.1.1.2.2.2 bouyer Previous Release: 347 1.1.1.2.2.2 bouyer Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 348 1.1.1.2.2.2 bouyer Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 349 1.1.1.2.2.2 bouyer Current Release: 350 1.1.1.2.2.2 bouyer Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total 351 1.1.1.2.2.2 bouyer Debug Version: 166.3K Code, 52.1K Data, 218.4K Total 352 1.1.1.2.2.2 bouyer 353 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 354 1.1.1.2.2.2 bouyer 355 1.1.1.2.2.2 bouyer iASL/Disassembler: Write ACPI errors to stderr instead of the output file. 356 1.1.1.2.2.2 bouyer This keeps the output files free of random error messages that may originate 357 1.1.1.2.2.2 bouyer from within the namespace/interpreter code. Used this opportunity to merge 358 1.1.1.2.2.2 bouyer all ACPI:-style messages into a single new module, utxferror.c. ACPICA BZ 359 1.1.1.2.2.2 bouyer 866. Lin Ming, Bob Moore. 360 1.1.1.2.2.2 bouyer 361 1.1.1.2.2.2 bouyer Tools: update some printfs for ansi warnings on size_t. Handle width change 362 1.1.1.2.2.2 bouyer of size_t on 32-bit versus 64-bit generations. Lin Ming. 363 1.1.1.2.2.2 bouyer 364 1.1.1.2.2.2 bouyer ---------------------------------------- 365 1.1.1.2.2.2 bouyer 06 August 2010. Summary of changes for version 20100806: 366 1.1.1.2.2.2 bouyer 367 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 368 1.1.1.2.2.2 bouyer 369 1.1.1.2.2.2 bouyer Designed and implemented a new host interface to the _OSI support code. This 370 1.1.1.2.2.2 bouyer will allow the host to dynamically add or remove multiple _OSI strings, as 371 1.1.1.2.2.2 bouyer well as install an optional handler that is called for each _OSI invocation. 372 1.1.1.2.2.2 bouyer Also added a new AML debugger command, 'osi' to display and modify the 373 1.1.1.2.2.2 bouyer global 374 1.1.1.2.2.2 bouyer _OSI string table, and test support in the AcpiExec utility. See the ACPICA 375 1.1.1.2.2.2 bouyer reference manual for full details. Lin Ming, Bob Moore. ACPICA BZ 836. 376 1.1.1.2.2.2 bouyer New Functions: 377 1.1.1.2.2.2 bouyer AcpiInstallInterface - Add an _OSI string. 378 1.1.1.2.2.2 bouyer AcpiRemoveInterface - Delete an _OSI string. 379 1.1.1.2.2.2 bouyer AcpiInstallInterfaceHandler - Install optional _OSI handler. 380 1.1.1.2.2.2 bouyer Obsolete Functions: 381 1.1.1.2.2.2 bouyer AcpiOsValidateInterface - no longer used. 382 1.1.1.2.2.2 bouyer New Files: 383 1.1.1.2.2.2 bouyer source/components/utilities/utosi.c 384 1.1.1.2.2.2 bouyer 385 1.1.1.2.2.2 bouyer Re-introduced the support to enable multi-byte transfers for Embedded 386 1.1.1.2.2.2 bouyer Controller (EC) operation regions. A reported problem was found to be a bug 387 1.1.1.2.2.2 bouyer in the host OS, not in the multi-byte support. Previously, the maximum data 388 1.1.1.2.2.2 bouyer size passed to the EC operation region handler was a single byte. There are 389 1.1.1.2.2.2 bouyer often EC Fields larger than one byte that need to be transferred, and it is 390 1.1.1.2.2.2 bouyer useful for the EC driver to lock these as a single transaction. This change 391 1.1.1.2.2.2 bouyer enables single transfers larger than 8 bits. This effectively changes the 392 1.1.1.2.2.2 bouyer access to the EC space from ByteAcc to AnyAcc, and will probably require 393 1.1.1.2.2.2 bouyer changes to the host OS Embedded Controller driver to enable 16/32/64/256-bit 394 1.1.1.2.2.2 bouyer transfers in addition to 8-bit transfers. Alexey Starikovskiy, Lin Ming. 395 1.1.1.2.2.2 bouyer 396 1.1.1.2.2.2 bouyer Fixed a problem with the prototype for AcpiOsReadPciConfiguration. The 397 1.1.1.2.2.2 bouyer prototype in acpiosxf.h had the output value pointer as a (void *). 398 1.1.1.2.2.2 bouyer It should be a (UINT64 *). This may affect some host OSL code. 399 1.1.1.2.2.2 bouyer 400 1.1.1.2.2.2 bouyer Fixed a couple problems with the recently modified Linux makefiles for iASL 401 1.1.1.2.2.2 bouyer and AcpiExec. These new makefiles place the generated object files in the 402 1.1.1.2.2.2 bouyer local directory so that there can be no collisions between the files that 403 1.1.1.2.2.2 bouyer are 404 1.1.1.2.2.2 bouyer shared between them that are compiled with different options. 405 1.1.1.2.2.2 bouyer 406 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 407 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 408 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 409 1.1.1.2.2.2 bouyer a 410 1.1.1.2.2.2 bouyer much larger code and data size. 411 1.1.1.2.2.2 bouyer 412 1.1.1.2.2.2 bouyer Previous Release: 413 1.1.1.2.2.2 bouyer Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 414 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 415 1.1.1.2.2.2 bouyer Current Release: 416 1.1.1.2.2.2 bouyer Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total 417 1.1.1.2.2.2 bouyer Debug Version: 165.1K Code, 51.9K Data, 217.0K Total 418 1.1.1.2.2.2 bouyer 419 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 420 1.1.1.2.2.2 bouyer 421 1.1.1.2.2.2 bouyer iASL/Disassembler: Added a new option (-da, "disassemble all") to load the 422 1.1.1.2.2.2 bouyer namespace from and disassemble an entire group of AML files. Useful for 423 1.1.1.2.2.2 bouyer loading all of the AML tables for a given machine (DSDT, SSDT1...SSDTn) and 424 1.1.1.2.2.2 bouyer disassembling with one simple command. ACPICA BZ 865. Lin Ming. 425 1.1.1.2.2.2 bouyer 426 1.1.1.2.2.2 bouyer iASL: Allow multiple invocations of -e option. This change allows multiple 427 1.1.1.2.2.2 bouyer uses of -e on the command line: "-e ssdt1.dat -e ssdt2.dat". ACPICA BZ 834. 428 1.1.1.2.2.2 bouyer Lin Ming. 429 1.1.1.2.2.2 bouyer 430 1.1.1.2.2.2 bouyer ---------------------------------------- 431 1.1.1.2.2.2 bouyer 02 July 2010. Summary of changes for version 20100702: 432 1.1.1.2.2.2 bouyer 433 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 434 1.1.1.2.2.2 bouyer 435 1.1.1.2.2.2 bouyer Implemented several updates to the recently added GPE reference count 436 1.1.1.2.2.2 bouyer support. The model for "wake" GPEs is changing to give the host OS complete 437 1.1.1.2.2.2 bouyer control of these GPEs. Eventually, the ACPICA core will not execute any _PRW 438 1.1.1.2.2.2 bouyer methods, since the host already must execute them. Also, additional changes 439 1.1.1.2.2.2 bouyer were made to help ensure that the reference counts are kept in proper 440 1.1.1.2.2.2 bouyer synchronization with reality. Rafael J. Wysocki. 441 1.1.1.2.2.2 bouyer 442 1.1.1.2.2.2 bouyer 1) Ensure that GPEs are not enabled twice during initialization. 443 1.1.1.2.2.2 bouyer 2) Ensure that GPE enable masks stay in sync with the reference count. 444 1.1.1.2.2.2 bouyer 3) Do not inadvertently enable GPEs when writing GPE registers. 445 1.1.1.2.2.2 bouyer 4) Remove the internal wake reference counter and add new AcpiGpeWakeup 446 1.1.1.2.2.2 bouyer interface. This interface will set or clear individual GPEs for wakeup. 447 1.1.1.2.2.2 bouyer 5) Remove GpeType argument from AcpiEnable and AcpiDisable. These interfaces 448 1.1.1.2.2.2 bouyer are now used for "runtime" GPEs only. 449 1.1.1.2.2.2 bouyer 450 1.1.1.2.2.2 bouyer Changed the behavior of the GPE install/remove handler interfaces. The GPE 451 1.1.1.2.2.2 bouyer is 452 1.1.1.2.2.2 bouyer no longer disabled during this process, as it was found to cause problems on 453 1.1.1.2.2.2 bouyer some machines. Rafael J. Wysocki. 454 1.1.1.2.2.2 bouyer 455 1.1.1.2.2.2 bouyer Reverted a change introduced in version 20100528 to enable Embedded 456 1.1.1.2.2.2 bouyer Controller multi-byte transfers. This change was found to cause problems 457 1.1.1.2.2.2 bouyer with 458 1.1.1.2.2.2 bouyer Index Fields and possibly Bank Fields. It will be reintroduced when these 459 1.1.1.2.2.2 bouyer problems have been resolved. 460 1.1.1.2.2.2 bouyer 461 1.1.1.2.2.2 bouyer Fixed a problem with references to Alias objects within Package Objects. A 462 1.1.1.2.2.2 bouyer reference to an Alias within the definition of a Package was not always 463 1.1.1.2.2.2 bouyer resolved properly. Aliases to objects like Processors, Thermal zones, etc. 464 1.1.1.2.2.2 bouyer were resolved to the actual object instead of a reference to the object as 465 1.1.1.2.2.2 bouyer it 466 1.1.1.2.2.2 bouyer should be. Package objects are only allowed to contain integer, string, 467 1.1.1.2.2.2 bouyer buffer, package, and reference objects. Redhat bugzilla 608648. 468 1.1.1.2.2.2 bouyer 469 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 470 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 471 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 472 1.1.1.2.2.2 bouyer a 473 1.1.1.2.2.2 bouyer much larger code and data size. 474 1.1.1.2.2.2 bouyer 475 1.1.1.2.2.2 bouyer Previous Release: 476 1.1.1.2.2.2 bouyer Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 477 1.1.1.2.2.2 bouyer Debug Version: 164.1K Code, 51.5K Data, 215.6K Total 478 1.1.1.2.2.2 bouyer Current Release: 479 1.1.1.2.2.2 bouyer Non-Debug Version: 88.3K Code, 18.8K Data, 107.1K Total 480 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 51.5K Data, 215.5K Total 481 1.1.1.2.2.2 bouyer 482 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 483 1.1.1.2.2.2 bouyer 484 1.1.1.2.2.2 bouyer iASL: Implemented a new compiler subsystem to allow definition and 485 1.1.1.2.2.2 bouyer compilation of the non-AML ACPI tables such as FADT, MADT, SRAT, etc. These 486 1.1.1.2.2.2 bouyer are called "ACPI Data Tables", and the new compiler is the "Data Table 487 1.1.1.2.2.2 bouyer Compiler". This compiler is intended to simplify the existing error-prone 488 1.1.1.2.2.2 bouyer process of creating these tables for the BIOS, as well as allowing the 489 1.1.1.2.2.2 bouyer disassembly, modification, recompilation, and override of existing ACPI data 490 1.1.1.2.2.2 bouyer tables. See the iASL User Guide for detailed information. 491 1.1.1.2.2.2 bouyer 492 1.1.1.2.2.2 bouyer iASL: Implemented a new Template Generator option in support of the new Data 493 1.1.1.2.2.2 bouyer Table Compiler. This option will create examples of all known ACPI tables 494 1.1.1.2.2.2 bouyer that can be used as the basis for table development. See the iASL 495 1.1.1.2.2.2 bouyer documentation and the -T option. 496 1.1.1.2.2.2 bouyer 497 1.1.1.2.2.2 bouyer Disassembler and headers: Added support for the WDDT ACPI table (Watchdog 498 1.1.1.2.2.2 bouyer Descriptor Table). 499 1.1.1.2.2.2 bouyer 500 1.1.1.2.2.2 bouyer Updated the Linux makefiles for iASL and AcpiExec to place the generated 501 1.1.1.2.2.2 bouyer object files in the local directory so that there can be no collisions 502 1.1.1.2.2.2 bouyer between the shared files between them that are generated with different 503 1.1.1.2.2.2 bouyer options. 504 1.1.1.2.2.2 bouyer 505 1.1.1.2.2.2 bouyer Added support for Mac OS X in the Unix OSL used for iASL and AcpiExec. Use 506 1.1.1.2.2.2 bouyer the #define __APPLE__ to enable this support. 507 1.1.1.2.2.2 bouyer 508 1.1.1.2.2.2 bouyer ---------------------------------------- 509 1.1.1.2.2.2 bouyer 28 May 2010. Summary of changes for version 20100528: 510 1.1.1.2.2.2 bouyer 511 1.1.1.2.2.2 bouyer Note: The ACPI 4.0a specification was released on April 5, 2010 and is 512 1.1.1.2.2.2 bouyer available at www.acpi.info. This is primarily an errata release. 513 1.1.1.2.2.2 bouyer 514 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 515 1.1.1.2.2.2 bouyer 516 1.1.1.2.2.2 bouyer Undefined ACPI tables: We are looking for the definitions for the following 517 1.1.1.2.2.2 bouyer ACPI tables that have been seen in the field: ATKG, IEIT, GSCI. 518 1.1.1.2.2.2 bouyer 519 1.1.1.2.2.2 bouyer Implemented support to enable multi-byte transfers for Embedded Controller 520 1.1.1.2.2.2 bouyer (EC) operation regions. Previously, the maximum data size passed to the EC 521 1.1.1.2.2.2 bouyer operation region handler was a single byte. There are often EC Fields larger 522 1.1.1.2.2.2 bouyer than one byte that need to be transferred, and it is useful for the EC 523 1.1.1.2.2.2 bouyer driver 524 1.1.1.2.2.2 bouyer to lock these as a single transaction. This change enables single transfers 525 1.1.1.2.2.2 bouyer larger than 8 bits. This effectively changes the access to the EC space from 526 1.1.1.2.2.2 bouyer ByteAcc to AnyAcc, and will probably require changes to the host OS Embedded 527 1.1.1.2.2.2 bouyer Controller driver to enable 16/32/64/256-bit transfers in addition to 8-bit 528 1.1.1.2.2.2 bouyer transfers. Alexey Starikovskiy, Lin Ming 529 1.1.1.2.2.2 bouyer 530 1.1.1.2.2.2 bouyer Implemented a performance enhancement for namespace search and access. This 531 1.1.1.2.2.2 bouyer change enhances the performance of namespace searches and walks by adding a 532 1.1.1.2.2.2 bouyer backpointer to the parent in each namespace node. On large namespaces, this 533 1.1.1.2.2.2 bouyer change can improve overall ACPI performance by up to 9X. Adding a pointer to 534 1.1.1.2.2.2 bouyer each namespace node increases the overall size of the internal namespace by 535 1.1.1.2.2.2 bouyer about 5%, since each namespace entry usually consists of both a namespace 536 1.1.1.2.2.2 bouyer node and an ACPI operand object. However, this is the first growth of the 537 1.1.1.2.2.2 bouyer namespace in ten years. ACPICA bugzilla 817. Alexey Starikovskiy. 538 1.1.1.2.2.2 bouyer 539 1.1.1.2.2.2 bouyer Implemented a performance optimization that reduces the number of namespace 540 1.1.1.2.2.2 bouyer walks. On control method exit, only walk the namespace if the method is 541 1.1.1.2.2.2 bouyer known 542 1.1.1.2.2.2 bouyer to have created namespace objects outside of its local scope. Previously, 543 1.1.1.2.2.2 bouyer the 544 1.1.1.2.2.2 bouyer entire namespace was traversed on each control method exit. This change can 545 1.1.1.2.2.2 bouyer improve overall ACPI performance by up to 3X. Alexey Starikovskiy, Bob 546 1.1.1.2.2.2 bouyer Moore. 547 1.1.1.2.2.2 bouyer 548 1.1.1.2.2.2 bouyer Added support to truncate I/O addresses to 16 bits for Windows 549 1.1.1.2.2.2 bouyer compatibility. 550 1.1.1.2.2.2 bouyer Some ASL code has been seen in the field that inadvertently has bits set 551 1.1.1.2.2.2 bouyer above bit 15. This feature is optional and is enabled if the BIOS requests 552 1.1.1.2.2.2 bouyer any Windows OSI strings. It can also be enabled by the host OS. Matthew 553 1.1.1.2.2.2 bouyer Garrett, Bob Moore. 554 1.1.1.2.2.2 bouyer 555 1.1.1.2.2.2 bouyer Added support to limit the maximum time for the ASL Sleep() operator. To 556 1.1.1.2.2.2 bouyer prevent accidental deep sleeps, limit the maximum time that Sleep() will 557 1.1.1.2.2.2 bouyer actually sleep. Configurable, the default maximum is two seconds. ACPICA 558 1.1.1.2.2.2 bouyer bugzilla 854. 559 1.1.1.2.2.2 bouyer 560 1.1.1.2.2.2 bouyer Added run-time validation support for the _WDG and_WED Microsoft predefined 561 1.1.1.2.2.2 bouyer methods. These objects are defined by "Windows Instrumentation", and are not 562 1.1.1.2.2.2 bouyer part of the ACPI spec. ACPICA BZ 860. 563 1.1.1.2.2.2 bouyer 564 1.1.1.2.2.2 bouyer Expanded all statistic counters used during namespace and device 565 1.1.1.2.2.2 bouyer initialization from 16 to 32 bits in order to support very large namespaces. 566 1.1.1.2.2.2 bouyer 567 1.1.1.2.2.2 bouyer Replaced all instances of %d in printf format specifiers with %u since 568 1.1.1.2.2.2 bouyer nearly 569 1.1.1.2.2.2 bouyer all integers in ACPICA are unsigned. 570 1.1.1.2.2.2 bouyer 571 1.1.1.2.2.2 bouyer Fixed the exception namestring for AE_WAKE_ONLY_GPE.

Handles the FADT-defined GPEs as well as GPE Block 611 1.1.1.2.2.2 bouyer Devices. Provides compatibility with other ACPI implementations. Two new 612 1.1.1.2.2.2 bouyer files added, evgpeinit.c and evgpeutil.c. ACPICA BZ 833. Lin Ming, Bob 613 1.1.1.2.2.2 bouyer Moore. 614 1.1.1.2.2.2 bouyer 615 1.1.1.2.2.2 bouyer Fixed a regression introduced in version 20100331 within the table manager 616 1.1.1.2.2.2 bouyer where initial table loading could fail. This was introduced in the fix for 617 1.1.1.2.2.2 bouyer AcpiReallocateRootTable. Also, renamed some of fields in the table manager 618 1.1.1.2.2.2 bouyer data structures to clarify their meaning and use. 619 1.1.1.2.2.2 bouyer 620 1.1.1.2.2.2 bouyer Fixed a possible allocation overrun during internal object copy in 621 1.1.1.2.2.2 bouyer AcpiUtCopySimpleObject. The original code did not correctly handle the case 622 1.1.1.2.2.2 bouyer where the object to be copied was a namespace node. Lin Ming. ACPICA BZ 847. 623 1.1.1.2.2.2 bouyer 624 1.1.1.2.2.2 bouyer Updated the allocation dump routine, AcpiUtDumpAllocation and fixed a 625 1.1.1.2.2.2 bouyer possible access beyond end-of-allocation. Also, now fully validate 626 1.1.1.2.2.2 bouyer descriptor 627 1.1.1.2.2.2 bouyer (size and type) before output. Lin Ming, Bob Moore.

This change implements validation for the address fields that 646 1.1.1.2.2.2 bouyer are common to all address-type resource descriptors. These checks are 647 1.1.1.2.2.2 bouyer implemented: Checks for valid Min/Max, length within the Min/Max window, 648 1.1.1.2.2.2 bouyer valid granularity, Min/Max a multiple of granularity, and _MIF/_MAF as per 649 1.1.1.2.2.2 bouyer table 6-40 in the ACPI 4.0a specification. Also split the large 650 1.1.1.2.2.2 bouyer aslrestype1.c 651 1.1.1.2.2.2 bouyer and aslrestype2.c files into five new files. ACPICA BZ 840. 652 1.1.1.2.2.2 bouyer 653 1.1.1.2.2.2 bouyer iASL: Added support for the _Wxx predefined names. This support was missing 654 1.1.1.2.2.2 bouyer and these names were not recognized by the compiler as valid predefined 655 1.1.1.2.2.2 bouyer names. ACPICA BZ 851. 656 1.1.1.2.2.2 bouyer 657 1.1.1.2.2.2 bouyer iASL: Added an error for all predefined names that are defined to return no 658 1.1.1.2.2.2 bouyer value and thus must be implemented as Control Methods. These include all of 659 1.1.1.2.2.2 bouyer the _Lxx, _Exx, _Wxx, and _Qxx names, as well as some other miscellaneous 660 1.1.1.2.2.2 bouyer names such as _DIS, _INI, _IRC, _OFF, _ON, and _PSx. ACPICA BZ 850, 856. 661 1.1.1.2.2.2 bouyer 662 1.1.1.2.2.2 bouyer iASL: Implemented the -ts option to emit hex AML data in ASL format, as an 663 1.1.1.2.2.2 bouyer ASL Buffer. Allows ACPI tables to be easily included within ASL files, to be 664 1.1.1.2.2.2 bouyer dynamically loaded via the Load() operator. Also cleaned up output for the - 665 1.1.1.2.2.2 bouyer ta and -tc options. ACPICA BZ 853. 666 1.1.1.2.2.2 bouyer 667 1.1.1.2.2.2 bouyer Tests: Added a new file with examples of extended iASL error checking. 668 1.1.1.2.2.2 bouyer Demonstrates the advanced error checking ability of the iASL compiler. 669 1.1.1.2.2.2 bouyer Available at tests/misc/badcode.asl. 670 1.1.1.2.2.2 bouyer 671 1.1.1.2.2.2 bouyer ---------------------------------------- 672 1.1.1.2.2.2 bouyer 31 March 2010. Summary of changes for version 20100331: 673 1.1.1.2.2.2 bouyer 674 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 675 1.1.1.2.2.2 bouyer 676 1.1.1.2.2.2 bouyer Completed a major update for the GPE support in order to improve support for 677 1.1.1.2.2.2 bouyer shared GPEs and to simplify both host OS and ACPICA code. Added a reference 678 1.1.1.2.2.2 bouyer count mechanism to support shared GPEs that require multiple device drivers. 679 1.1.1.2.2.2 bouyer Several external interfaces have changed. One external interface has been 680 1.1.1.2.2.2 bouyer removed. One new external interface was added. Most of the GPE external 681 1.1.1.2.2.2 bouyer interfaces now use the GPE spinlock instead of the events mutex (and the 682 1.1.1.2.2.2 bouyer Flags parameter for many GPE interfaces has been removed.) See the updated 683 1.1.1.2.2.2 bouyer ACPICA Programmer Reference for details. Matthew Garrett, Bob Moore, Rafael 684 1.1.1.2.2.2 bouyer Wysocki. ACPICA BZ 831. 685 1.1.1.2.2.2 bouyer 686 1.1.1.2.2.2 bouyer Changed: 687 1.1.1.2.2.2 bouyer AcpiEnableGpe, AcpiDisableGpe, AcpiClearGpe, AcpiGetGpeStatus 688 1.1.1.2.2.2 bouyer Removed: 689 1.1.1.2.2.2 bouyer AcpiSetGpeType 690 1.1.1.2.2.2 bouyer New: 691 1.1.1.2.2.2 bouyer AcpiSetGpe 692 1.1.1.2.2.2 bouyer 693 1.1.1.2.2.2 bouyer Implemented write support for DataTable operation regions. These regions are 694 1.1.1.2.2.2 bouyer defined via the DataTableRegion() operator. Previously, only read support 695 1.1.1.2.2.2 bouyer was 696 1.1.1.2.2.2 bouyer implemented. The ACPI specification allows DataTableRegions to be 697 1.1.1.2.2.2 bouyer read/write, 698 1.1.1.2.2.2 bouyer however. 699 1.1.1.2.2.2 bouyer 700 1.1.1.2.2.2 bouyer Implemented a new subsystem option to force a copy of the DSDT to local 701 1.1.1.2.2.2 bouyer memory. Optionally copy the entire DSDT to local memory (instead of simply 702 1.1.1.2.2.2 bouyer mapping it.) There are some (albeit very rare) BIOSs that corrupt or replace 703 1.1.1.2.2.2 bouyer the original DSDT, creating the need for this option. Default is FALSE, do 704 1.1.1.2.2.2 bouyer not copy the DSDT. 705 1.1.1.2.2.2 bouyer 706 1.1.1.2.2.2 bouyer Implemented detection of a corrupted or replaced DSDT. This change adds 707 1.1.1.2.2.2 bouyer support to detect a DSDT that has been corrupted and/or replaced from 708 1.1.1.2.2.2 bouyer outside 709 1.1.1.2.2.2 bouyer the OS (by firmware). This is typically catastrophic for the system, but has 710 1.1.1.2.2.2 bouyer been seen on some machines. Once this problem has been detected, the DSDT 711 1.1.1.2.2.2 bouyer copy option can be enabled via system configuration. Lin Ming, Bob Moore. 712 1.1.1.2.2.2 bouyer 713 1.1.1.2.2.2 bouyer Fixed two problems with AcpiReallocateRootTable during the root table copy. 714 1.1.1.2.2.2 bouyer When copying the root table to the new allocation, the length used was 715 1.1.1.2.2.2 bouyer incorrect. The new size was used instead of the current table size, meaning 716 1.1.1.2.2.2 bouyer too much data was copied. Also, the count of available slots for ACPI tables 717 1.1.1.2.2.2 bouyer was not set correctly. Alexey Starikovskiy, Bob Moore. 718 1.1.1.2.2.2 bouyer 719 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 720 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

The type of any returned static (unnamed) object is now 736 1.1.1.2.2.2 bouyer validated. For example, Return(1). ACPICA BZ 786. 737 1.1.1.2.2.2 bouyer 738 1.1.1.2.2.2 bouyer iASL: Fixed a predefined name object verification regression. Fixes a 739 1.1.1.2.2.2 bouyer problem 740 1.1.1.2.2.2 bouyer introduced in version 20100304. An error is incorrectly generated if a 741 1.1.1.2.2.2 bouyer predefined name is declared as a static named object with a value defined 742 1.1.1.2.2.2 bouyer using the keywords "Zero", "One", or "Ones". Lin Ming. 743 1.1.1.2.2.2 bouyer 744 1.1.1.2.2.2 bouyer iASL: Added Windows 7 support for the -g option (get local ACPI tables) by 745 1.1.1.2.2.2 bouyer reducing the requested registry access rights. ACPICA BZ 842. 746 1.1.1.2.2.2 bouyer 747 1.1.1.2.2.2 bouyer Disassembler: fixed a possible fault when generating External() statements. 748 1.1.1.2.2.2 bouyer Introduced in commit ae7d6fd: Properly handle externals with parent-prefix 749 1.1.1.2.2.2 bouyer (carat). Fixes a string length allocation calculation. Lin Ming. 750 1.1.1.2.2.2 bouyer 751 1.1.1.2.2.2 bouyer ---------------------------------------- 752 1.1.1.2.2.2 bouyer 04 March 2010.

FreeBSD report 140979. 762 1.1.1.2.2.2 bouyer Lin 763 1.1.1.2.2.2 bouyer Ming. 764 1.1.1.2.2.2 bouyer 765 1.1.1.2.2.2 bouyer Implemented additional configuration support for the AML "Debug Object". 766 1.1.1.2.2.2 bouyer Output from the debug object can now be enabled via a global variable, 767 1.1.1.2.2.2 bouyer AcpiGbl_EnableAmlDebugObject. This will assist with remote machine 768 1.1.1.2.2.2 bouyer debugging. 769 1.1.1.2.2.2 bouyer This debug output is now available in the release version of ACPICA instead 770 1.1.1.2.2.2 bouyer of just the debug version. Also, the entire debug output module can now be 771 1.1.1.2.2.2 bouyer configured out of the ACPICA build if desired. One new file added, 772 1.1.1.2.2.2 bouyer executer/exdebug.c. Lin Ming, Bob Moore. 773 1.1.1.2.2.2 bouyer 774 1.1.1.2.2.2 bouyer Added header support for the ACPI MCHI table (Management Controller Host 775 1.1.1.2.2.2 bouyer Interface Table). This table was added in ACPI 4.0, but the defining 776 1.1.1.2.2.2 bouyer document 777 1.1.1.2.2.2 bouyer has only recently become available. 778 1.1.1.2.2.2 bouyer 779 1.1.1.2.2.2 bouyer Standardized output of integer values for ACPICA warnings/errors. Always use 780 1.1.1.2.2.2 bouyer 0x prefix for hex output, always use %u for unsigned integer decimal output. 781 1.1.1.2.2.2 bouyer Affects ACPI_INFO, ACPI_ERROR, ACPI_EXCEPTION, and ACPI_WARNING (about 400 782 1.1.1.2.2.2 bouyer invocations.) These invocations were converted from the original 783 1.1.1.2.2.2 bouyer ACPI_DEBUG_PRINT invocations and were not consistent.

For 802 1.1.1.2.2.2 bouyer example, the type of this object is now validated to be of type Integer: 803 1.1.1.2.2.2 bouyer Name(_BBN, 1). This change migrates the compiler to using the core 804 1.1.1.2.2.2 bouyer predefined 805 1.1.1.2.2.2 bouyer name table instead of maintaining a local version. Added a new file, 806 1.1.1.2.2.2 bouyer aslpredef.c. ACPICA BZ 832. 807 1.1.1.2.2.2 bouyer 808 1.1.1.2.2.2 bouyer Disassembler: Added support for the ACPI 4.0 MCHI table. 809 1.1.1.2.2.2 bouyer 810 1.1.1.2.2.2 bouyer ---------------------------------------- 811 1.1.1.2.2.2 bouyer 21 January 2010. Summary of changes for version 20100121: 812 1.1.1.2.2.2 bouyer 813 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 814 1.1.1.2.2.2 bouyer 815 1.1.1.2.2.2 bouyer Added the 2010 copyright to all module headers and signons. This affects 816 1.1.1.2.2.2 bouyer virtually every file in the ACPICA core subsystem, the iASL compiler, the 817 1.1.1.2.2.2 bouyer tools/utilities, and the test suites. 818 1.1.1.2.2.2 bouyer 819 1.1.1.2.2.2 bouyer Implemented a change to the AcpiGetDevices interface to eliminate 820 1.1.1.2.2.2 bouyer unnecessary 821 1.1.1.2.2.2 bouyer invocations of the _STA method. In the case where a specific _HID is 822 1.1.1.2.2.2 bouyer requested, do not run _STA until a _HID match is found. This eliminates 823 1.1.1.2.2.2 bouyer potentially dozens of _STA calls during a search for a particular 824 1.1.1.2.2.2 bouyer device/HID, 825 1.1.1.2.2.2 bouyer which in turn can improve boot times. ACPICA BZ 828. Lin Ming. 826 1.1.1.2.2.2 bouyer 827 1.1.1.2.2.2 bouyer Implemented an additional repair for predefined method return values. 828 1.1.1.2.2.2 bouyer Attempt 829 1.1.1.2.2.2 bouyer to repair unexpected NULL elements within returned Package objects. Create 830 1.1.1.2.2.2 bouyer an 831 1.1.1.2.2.2 bouyer Integer of value zero, a NULL String, or a zero-length Buffer as 832 1.1.1.2.2.2 bouyer appropriate. 833 1.1.1.2.2.2 bouyer ACPICA BZ 818. Lin Ming, Bob Moore. 834 1.1.1.2.2.2 bouyer 835 1.1.1.2.2.2 bouyer Removed the obsolete ACPI_INTEGER data type. This type was introduced as the 836 1.1.1.2.2.2 bouyer code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with 837 1.1.1.2.2.2 bouyer 64-bit AML integers). It is now obsolete and this change removes it from the 838 1.1.1.2.2.2 bouyer ACPICA code base, replaced by UINT64. The original typedef has been retained 839 1.1.1.2.2.2 bouyer for now for compatibility with existing device driver code. ACPICA BZ 824. 840 1.1.1.2.2.2 bouyer 841 1.1.1.2.2.2 bouyer Removed the unused UINT32_STRUCT type, and the obsolete Integer64 field in 842 1.1.1.2.2.2 bouyer the parse tree object. 843 1.1.1.2.2.2 bouyer 844 1.1.1.2.2.2 bouyer Added additional warning options for the gcc-4 generation. Updated the 845 1.1.1.2.2.2 bouyer source 846 1.1.1.2.2.2 bouyer accordingly. This includes some code restructuring to eliminate unreachable 847 1.1.1.2.2.2 bouyer code, elimination of some gotos, elimination of unused return values, some 848 1.1.1.2.2.2 bouyer additional casting, and removal of redundant declarations. 849 1.1.1.2.2.2 bouyer 850 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 851 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 852 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 853 1.1.1.2.2.2 bouyer a 854 1.1.1.2.2.2 bouyer much larger code and data size. 855 1.1.1.2.2.2 bouyer 856 1.1.1.2.2.2 bouyer Previous Release: 857 1.1.1.2.2.2 bouyer Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 858 1.1.1.2.2.2 bouyer Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 859 1.1.1.2.2.2 bouyer Current Release: 860 1.1.1.2.2.2 bouyer Non-Debug Version: 87.1K Code, 18.0K Data, 105.1K Total 861 1.1.1.2.2.2 bouyer Debug Version: 163.5K Code, 50.9K Data, 214.4K Total 862 1.1.1.2.2.2 bouyer 863 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 864 1.1.1.2.2.2 bouyer 865 1.1.1.2.2.2 bouyer No functional changes for this release. 866 1.1.1.2.2.2 bouyer 867 1.1.1.2.2.2 bouyer ---------------------------------------- 868 1.1.1.2.2.2 bouyer 14 December 2009. Summary of changes for version 20091214: 869 1.1.1.2.2.2 bouyer 870 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 871 1.1.1.2.2.2 bouyer 872 1.1.1.2.2.2 bouyer Enhanced automatic data type conversions for predefined name repairs. This 873 1.1.1.2.2.2 bouyer change expands the automatic repairs/conversions for predefined name return 874 1.1.1.2.2.2 bouyer values to make Integers, Strings, and Buffers fully interchangeable. Also, a 875 1.1.1.2.2.2 bouyer Buffer can be converted to a Package of Integers if necessary. The 876 1.1.1.2.2.2 bouyer nsrepair.c 877 1.1.1.2.2.2 bouyer module was completely restructured. Lin Ming, Bob Moore. 878 1.1.1.2.2.2 bouyer 879 1.1.1.2.2.2 bouyer Implemented automatic removal of null package elements during predefined 880 1.1.1.2.2.2 bouyer name 881 1.1.1.2.2.2 bouyer repairs. This change will automatically remove embedded and trailing NULL 882 1.1.1.2.2.2 bouyer package elements from returned package objects that are defined to contain a 883 1.1.1.2.2.2 bouyer variable number of sub-packages. The driver is then presented with a package 884 1.1.1.2.2.2 bouyer with no null elements to deal with. ACPICA BZ 819. 885 1.1.1.2.2.2 bouyer 886 1.1.1.2.2.2 bouyer Implemented a repair for the predefined _FDE and _GTM names. The expected 887 1.1.1.2.2.2 bouyer return value for both names is a Buffer of 5 DWORDs. This repair fixes two 888 1.1.1.2.2.2 bouyer possible problems (both seen in the field), where a package of integers is 889 1.1.1.2.2.2 bouyer returned, or a buffer of BYTEs is returned. With assistance from Jung-uk 890 1.1.1.2.2.2 bouyer Kim. 891 1.1.1.2.2.2 bouyer 892 1.1.1.2.2.2 bouyer Implemented additional module-level code support. This change will properly 893 1.1.1.2.2.2 bouyer execute module-level code that is not at the root of the namespace (under a 894 1.1.1.2.2.2 bouyer Device object, etc.). Now executes the code within the current scope instead 895 1.1.1.2.2.2 bouyer of the root. ACPICA BZ 762. Lin Ming. 896 1.1.1.2.2.2 bouyer 897 1.1.1.2.2.2 bouyer Fixed possible mutex acquisition errors when running _REG methods. Fixes a 898 1.1.1.2.2.2 bouyer problem where mutex errors can occur when running a _REG method that is in 899 1.1.1.2.2.2 bouyer the same scope as a method-defined operation region or an operation region 900 1.1.1.2.2.2 bouyer under a module-level IF block. This type of code is rare, so the problem has 901 1.1.1.2.2.2 bouyer not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore. 902 1.1.1.2.2.2 bouyer 903 1.1.1.2.2.2 bouyer Fixed a possible memory leak during module-level code execution. An object 904 1.1.1.2.2.2 bouyer could be leaked for each block of executed module-level code if the 905 1.1.1.2.2.2 bouyer interpreter slack mode is enabled This change deletes any implicitly 906 1.1.1.2.2.2 bouyer returned 907 1.1.1.2.2.2 bouyer object from the module-level code block. Lin Ming. 908 1.1.1.2.2.2 bouyer 909 1.1.1.2.2.2 bouyer Removed messages for successful predefined repair(s). The repair mechanism 910 1.1.1.2.2.2 bouyer was considered too wordy. Now, messages are only unconditionally emitted if 911 1.1.1.2.2.2 bouyer the return object cannot be repaired. Existing messages for successful 912 1.1.1.2.2.2 bouyer repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827. 913 1.1.1.2.2.2 bouyer 914 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 915 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 916 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 917 1.1.1.2.2.2 bouyer a 918 1.1.1.2.2.2 bouyer much larger code and data size. 919 1.1.1.2.2.2 bouyer 920 1.1.1.2.2.2 bouyer Previous Release: 921 1.1.1.2.2.2 bouyer Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 922 1.1.1.2.2.2 bouyer Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 923 1.1.1.2.2.2 bouyer Current Release: 924 1.1.1.2.2.2 bouyer Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total 925 1.1.1.2.2.2 bouyer Debug Version: 163.4K Code, 50.8K Data, 214.2K Total 926 1.1.1.2.2.2 bouyer 927 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 928 1.1.1.2.2.2 bouyer 929 1.1.1.2.2.2 bouyer iASL: Fixed a regression introduced in 20091112 where intermediate .SRC 930 1.1.1.2.2.2 bouyer files 931 1.1.1.2.2.2 bouyer were no longer automatically removed at the termination of the compile. 932 1.1.1.2.2.2 bouyer 933 1.1.1.2.2.2 bouyer acpiexec: Implemented the -f option to specify default region fill value. 934 1.1.1.2.2.2 bouyer This option specifies the value used to initialize buffers that simulate 935 1.1.1.2.2.2 bouyer operation regions. Default value is zero. Useful for debugging problems that 936 1.1.1.2.2.2 bouyer depend on a specific initial value for a region or field. 937 1.1.1.2.2.2 bouyer 938 1.1.1.2.2.2 bouyer ---------------------------------------- 939 1.1.1.2.2.2 bouyer 12 November 2009. Summary of changes for version 20091112: 940 1.1.1.2.2.2 bouyer 941 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 942 1.1.1.2.2.2 bouyer 943 1.1.1.2.2.2 bouyer Implemented a post-order callback to AcpiWalkNamespace. The existing 944 1.1.1.2.2.2 bouyer interface only has a pre-order callback. This change adds an additional 945 1.1.1.2.2.2 bouyer parameter for a post-order callback which will be more useful for bus scans. 946 1.1.1.2.2.2 bouyer ACPICA BZ 779. Lin Ming. Updated the ACPICA Programmer Reference. 947 1.1.1.2.2.2 bouyer 948 1.1.1.2.2.2 bouyer Modified the behavior of the operation region memory mapping cache for 949 1.1.1.2.2.2 bouyer SystemMemory. Ensure that the memory mappings created for operation regions 950 1.1.1.2.2.2 bouyer do not cross 4K page boundaries. Crossing a page boundary while mapping 951 1.1.1.2.2.2 bouyer regions can cause kernel warnings on some hosts if the pages have different 952 1.1.1.2.2.2 bouyer attributes. Such regions are probably BIOS bugs, and this is the workaround. 953 1.1.1.2.2.2 bouyer Linux BZ 14445. Lin Ming. 954 1.1.1.2.2.2 bouyer 955 1.1.1.2.2.2 bouyer Implemented an automatic repair for predefined methods that must return 956 1.1.1.2.2.2 bouyer sorted lists. This change will repair (by sorting) packages returned by 957 1.1.1.2.2.2 bouyer _ALR, 958 1.1.1.2.2.2 bouyer _PSS, and _TSS. Drivers can now assume that the packages are correctly 959 1.1.1.2.2.2 bouyer sorted 960 1.1.1.2.2.2 bouyer and do not contain NULL package elements. Adds one new file, 961 1.1.1.2.2.2 bouyer namespace/nsrepair2.c. ACPICA BZ 784. Lin Ming, Bob Moore. 962 1.1.1.2.2.2 bouyer 963 1.1.1.2.2.2 bouyer Fixed a possible fault during predefined name validation if a return Package 964 1.1.1.2.2.2 bouyer object contains NULL elements. Also adds a warning if a NULL element is 965 1.1.1.2.2.2 bouyer followed by any non-null elements. ACPICA BZ 813, 814. Future enhancement 966 1.1.1.2.2.2 bouyer may 967 1.1.1.2.2.2 bouyer include repair or removal of all such NULL elements where possible. 968 1.1.1.2.2.2 bouyer 969 1.1.1.2.2.2 bouyer Implemented additional module-level executable AML code support. This change 970 1.1.1.2.2.2 bouyer will execute module-level code that is not at the root of the namespace 971 1.1.1.2.2.2 bouyer (under a Device object, etc.) at table load time. Module-level executable 972 1.1.1.2.2.2 bouyer AML 973 1.1.1.2.2.2 bouyer code has been illegal since ACPI 2.0. ACPICA BZ 762. Lin Ming. 974 1.1.1.2.2.2 bouyer 975 1.1.1.2.2.2 bouyer Implemented a new internal function to create Integer objects. This function 976 1.1.1.2.2.2 bouyer simplifies miscellaneous object creation code. ACPICA BZ 823. 977 1.1.1.2.2.2 bouyer 978 1.1.1.2.2.2 bouyer Reduced the severity of predefined repair messages, Warning to Info. Since 979 1.1.1.2.2.2 bouyer the object was successfully repaired, a warning is too severe. Reduced to an 980 1.1.1.2.2.2 bouyer info message for now. These messages may eventually be changed to debug- 981 1.1.1.2.2.2 bouyer only. 982 1.1.1.2.2.2 bouyer ACPICA BZ 812. 983 1.1.1.2.2.2 bouyer 984 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 985 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 986 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 987 1.1.1.2.2.2 bouyer a 988 1.1.1.2.2.2 bouyer much larger code and data size. 989 1.1.1.2.2.2 bouyer 990 1.1.1.2.2.2 bouyer Previous Release: 991 1.1.1.2.2.2 bouyer Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total 992 1.1.1.2.2.2 bouyer Debug Version: 161.8K Code, 50.6K Data, 212.4K Total 993 1.1.1.2.2.2 bouyer Current Release: 994 1.1.1.2.2.2 bouyer Non-Debug Version: 86.6K Code, 18.2K Data, 104.8K Total 995 1.1.1.2.2.2 bouyer Debug Version: 162.7K Code, 50.8K Data, 213.5K Total 996 1.1.1.2.2.2 bouyer 997 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 998 1.1.1.2.2.2 bouyer 999 1.1.1.2.2.2 bouyer iASL: Implemented Switch() with While(1) so that Break works correctly. This 1000 1.1.1.2.2.2 bouyer change correctly implements the Switch operator with a surrounding While(1) 1001 1.1.1.2.2.2 bouyer so that the Break operator works as expected. ACPICA BZ 461. Lin Ming. 1002 1.1.1.2.2.2 bouyer 1003 1.1.1.2.2.2 bouyer iASL: Added a message if a package initializer list is shorter than package 1004 1.1.1.2.2.2 bouyer length. Adds a new remark for a Package() declaration if an initializer list 1005 1.1.1.2.2.2 bouyer exists, but is shorter than the declared length of the package. Although 1006 1.1.1.2.2.2 bouyer technically legal, this is probably a coding error and it is seen in the 1007 1.1.1.2.2.2 bouyer field. ACPICA BZ 815. Lin Ming, Bob Moore. 1008 1.1.1.2.2.2 bouyer 1009 1.1.1.2.2.2 bouyer iASL: Fixed a problem where the compiler could fault after the maximum 1010 1.1.1.2.2.2 bouyer number 1011 1.1.1.2.2.2 bouyer of errors was reached (200). 1012 1.1.1.2.2.2 bouyer 1013 1.1.1.2.2.2 bouyer acpixtract: Fixed a possible warning for pointer cast if the compiler 1014 1.1.1.2.2.2 bouyer warning 1015 1.1.1.2.2.2 bouyer level set very high. 1016 1.1.1.2.2.2 bouyer 1017 1.1.1.2.2.2 bouyer ---------------------------------------- 1018 1.1.1.2.2.2 bouyer 13 October 2009. Summary of changes for version 20091013: 1019 1.1.1.2.2.2 bouyer 1020 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1021 1.1.1.2.2.2 bouyer 1022 1.1.1.2.2.2 bouyer Fixed a problem where an Operation Region _REG method could be executed more 1023 1.1.1.2.2.2 bouyer than once. If a custom address space handler is installed by the host before 1024 1.1.1.2.2.2 bouyer the "initialize operation regions" phase of the ACPICA initialization, any 1025 1.1.1.2.2.2 bouyer _REG methods for that address space could be executed twice. This change 1026 1.1.1.2.2.2 bouyer fixes the problem. ACPICA BZ 427. Lin Ming. 1027 1.1.1.2.2.2 bouyer 1028 1.1.1.2.2.2 bouyer Fixed a possible memory leak for the Scope() ASL operator. When the exact 1029 1.1.1.2.2.2 bouyer invocation of "Scope(\)" is executed (change scope to root), one internal 1030 1.1.1.2.2.2 bouyer operand object was leaked. Lin Ming. 1031 1.1.1.2.2.2 bouyer 1032 1.1.1.2.2.2 bouyer Implemented a run-time repair for the _MAT predefined method. If the _MAT 1033 1.1.1.2.2.2 bouyer return value is defined as a Field object in the AML, and the field 1034 1.1.1.2.2.2 bouyer size is less than or equal to the default width of an integer (32 or 1035 1.1.1.2.2.2 bouyer 64),_MAT 1036 1.1.1.2.2.2 bouyer can incorrectly return an Integer instead of a Buffer. ACPICA now 1037 1.1.1.2.2.2 bouyer automatically repairs this problem. ACPICA BZ 810. 1038 1.1.1.2.2.2 bouyer 1039 1.1.1.2.2.2 bouyer Implemented a run-time repair for the _BIF and _BIX predefined methods. The 1040 1.1.1.2.2.2 bouyer "OEM Information" field is often incorrectly returned as an Integer with 1041 1.1.1.2.2.2 bouyer value zero if the field is not supported by the platform. This is due to an 1042 1.1.1.2.2.2 bouyer ambiguity in the ACPI specification.

Summary of changes for version 20090903: 1080 1.1.1.2.2.2 bouyer 1081 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1082 1.1.1.2.2.2 bouyer 1083 1.1.1.2.2.2 bouyer For Windows Vista compatibility, added the automatic execution of an _INI 1084 1.1.1.2.2.2 bouyer method located at the namespace root (\_INI). This method is executed at 1085 1.1.1.2.2.2 bouyer table load time. This support is in addition to the automatic execution of 1086 1.1.1.2.2.2 bouyer \_SB._INI. Lin Ming. 1087 1.1.1.2.2.2 bouyer 1088 1.1.1.2.2.2 bouyer Fixed a possible memory leak in the interpreter for AML package objects if 1089 1.1.1.2.2.2 bouyer the package initializer list is longer than the defined size of the package. 1090 1.1.1.2.2.2 bouyer This apparently can only happen if the BIOS changes the package size on the 1091 1.1.1.2.2.2 bouyer fly (seen in a _PSS object), as ASL compilers do not allow this. The 1092 1.1.1.2.2.2 bouyer interpreter will truncate the package to the defined size (and issue an 1093 1.1.1.2.2.2 bouyer error 1094 1.1.1.2.2.2 bouyer message), but previously could leave the extra objects undeleted if they 1095 1.1.1.2.2.2 bouyer were 1096 1.1.1.2.2.2 bouyer pre-created during the argument processing (such is the case if the package 1097 1.1.1.2.2.2 bouyer consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805. 1098 1.1.1.2.2.2 bouyer 1099 1.1.1.2.2.2 bouyer Fixed a problem seen when a Buffer or String is stored to itself via ASL. 1100 1.1.1.2.2.2 bouyer This has been reported in the field. Previously, ACPICA would zero out the 1101 1.1.1.2.2.2 bouyer buffer/string. Now, the operation is treated as a noop. Provides Windows 1102 1.1.1.2.2.2 bouyer compatibility. ACPICA BZ 803. Lin Ming. 1103 1.1.1.2.2.2 bouyer 1104 1.1.1.2.2.2 bouyer Removed an extraneous error message for ASL constructs of the form 1105 1.1.1.2.2.2 bouyer Store(LocalX,LocalX) when LocalX is uninitialized. These curious statements 1106 1.1.1.2.2.2 bouyer are seen in many BIOSs and are once again treated as NOOPs and no error is 1107 1.1.1.2.2.2 bouyer emitted when they are encountered. ACPICA BZ 785. 1108 1.1.1.2.2.2 bouyer 1109 1.1.1.2.2.2 bouyer Fixed an extraneous warning message if a _DSM reserved method returns a 1110 1.1.1.2.2.2 bouyer Package object. _DSM can return any type of object, so validation on the 1111 1.1.1.2.2.2 bouyer return type cannot be performed. ACPICA BZ 802. 1112 1.1.1.2.2.2 bouyer 1113 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1114 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

The correct alias is now constructed and no error is emitted. 1130 1.1.1.2.2.2 bouyer ACPICA BZ 738. 1131 1.1.1.2.2.2 bouyer 1132 1.1.1.2.2.2 bouyer iASL: Implemented the -I option to specify additional search directories for 1133 1.1.1.2.2.2 bouyer include files. Allows multiple additional search paths for include files. 1134 1.1.1.2.2.2 bouyer Directories are searched in the order specified on the command line (after 1135 1.1.1.2.2.2 bouyer the local directory is searched.) ACPICA BZ 800. 1136 1.1.1.2.2.2 bouyer 1137 1.1.1.2.2.2 bouyer iASL: Fixed a problem where the full pathname for include files was not 1138 1.1.1.2.2.2 bouyer emitted for warnings/errors. This caused the IDE support to not work 1139 1.1.1.2.2.2 bouyer properly. ACPICA BZ 765. 1140 1.1.1.2.2.2 bouyer 1141 1.1.1.2.2.2 bouyer iASL: Implemented the -@ option to specify a Windows-style response file 1142 1.1.1.2.2.2 bouyer containing additional command line options. ACPICA BZ 801. 1143 1.1.1.2.2.2 bouyer 1144 1.1.1.2.2.2 bouyer AcpiExec: Added support to load multiple AML files simultaneously (such as a 1145 1.1.1.2.2.2 bouyer DSDT and multiple SSDTs). Also added support for wildcards within the AML 1146 1.1.1.2.2.2 bouyer pathname. These features allow all machine tables to be easily loaded and 1147 1.1.1.2.2.2 bouyer debugged together. ACPICA BZ 804. 1148 1.1.1.2.2.2 bouyer 1149 1.1.1.2.2.2 bouyer Disassembler: Added missing support for disassembly of HEST table Error Bank 1150 1.1.1.2.2.2 bouyer subtables. 1151 1.1.1.2.2.2 bouyer 1152 1.1.1.2.2.2 bouyer ---------------------------------------- 1153 1.1.1.2.2.2 bouyer 30 July 2009. Summary of changes for version 20090730: 1154 1.1.1.2.2.2 bouyer 1155 1.1.1.2.2.2 bouyer The ACPI 4.0 implementation for ACPICA is complete with this release. 1156 1.1.1.2.2.2 bouyer 1157 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1158 1.1.1.2.2.2 bouyer 1159 1.1.1.2.2.2 bouyer ACPI 4.0: Added header file support for all new and changed ACPI tables. 1160 1.1.1.2.2.2 bouyer Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new 1161 1.1.1.2.2.2 bouyer for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT, 1162 1.1.1.2.2.2 bouyer EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There 1163 1.1.1.2.2.2 bouyer have been some ACPI 4.0 changes to other existing tables. Split the large 1164 1.1.1.2.2.2 bouyer actbl1.h header into the existing actbl2.h header. ACPICA BZ 774. 1165 1.1.1.2.2.2 bouyer 1166 1.1.1.2.2.2 bouyer ACPI 4.0: Implemented predefined name validation for all new names. There 1167 1.1.1.2.2.2 bouyer are 1168 1.1.1.2.2.2 bouyer 31 new names in ACPI 4.0. The predefined validation module was split into 1169 1.1.1.2.2.2 bouyer two 1170 1.1.1.2.2.2 bouyer files. The new file is namespace/nsrepair.c. ACPICA BZ 770. 1171 1.1.1.2.2.2 bouyer 1172 1.1.1.2.2.2 bouyer Implemented support for so-called "module-level executable code". This is 1173 1.1.1.2.2.2 bouyer executable AML code that exists outside of any control method and is 1174 1.1.1.2.2.2 bouyer intended 1175 1.1.1.2.2.2 bouyer to be executed at table load time. Although illegal since ACPI 2.0, this 1176 1.1.1.2.2.2 bouyer type 1177 1.1.1.2.2.2 bouyer of code still exists and is apparently still being created. Blocks of this 1178 1.1.1.2.2.2 bouyer code are now detected and executed as intended. Currently, the code blocks 1179 1.1.1.2.2.2 bouyer must exist under either an If, Else, or While construct; these are the 1180 1.1.1.2.2.2 bouyer typical cases seen in the field. ACPICA BZ 762. Lin Ming. 1181 1.1.1.2.2.2 bouyer 1182 1.1.1.2.2.2 bouyer Implemented an automatic dynamic repair for predefined names that return 1183 1.1.1.2.2.2 bouyer nested Package objects. This applies to predefined names that are defined to 1184 1.1.1.2.2.2 bouyer return a variable-length Package of sub-packages. If the number of sub- 1185 1.1.1.2.2.2 bouyer packages is one, BIOS code is occasionally seen that creates a simple single 1186 1.1.1.2.2.2 bouyer package with no sub-packages. This code attempts to fix the problem by 1187 1.1.1.2.2.2 bouyer wrapping a new package object around the existing package. These methods can 1188 1.1.1.2.2.2 bouyer be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ 1189 1.1.1.2.2.2 bouyer 790. 1190 1.1.1.2.2.2 bouyer 1191 1.1.1.2.2.2 bouyer Fixed a regression introduced in 20090625 for the AcpiGetDevices interface. 1192 1.1.1.2.2.2 bouyer The _HID/_CID matching was broken and no longer matched IDs correctly. 1193 1.1.1.2.2.2 bouyer ACPICA 1194 1.1.1.2.2.2 bouyer BZ 793. 1195 1.1.1.2.2.2 bouyer 1196 1.1.1.2.2.2 bouyer Fixed a problem with AcpiReset where the reset would silently fail if the 1197 1.1.1.2.2.2 bouyer register was one of the protected I/O ports. AcpiReset now bypasses the port 1198 1.1.1.2.2.2 bouyer validation mechanism. This may eventually be driven into the AcpiRead/Write 1199 1.1.1.2.2.2 bouyer interfaces. 1200 1.1.1.2.2.2 bouyer 1201 1.1.1.2.2.2 bouyer Fixed a regression related to the recent update of the AcpiRead/Write 1202 1.1.1.2.2.2 bouyer interfaces. A sleep/suspend could fail if the optional PM2 Control register 1203 1.1.1.2.2.2 bouyer does not exist during an attempt to write the Bus Master Arbitration bit. 1204 1.1.1.2.2.2 bouyer (However, some hosts already delete the code that writes this bit, and the 1205 1.1.1.2.2.2 bouyer code may in fact be obsolete at this date.) ACPICA BZ 799. 1206 1.1.1.2.2.2 bouyer 1207 1.1.1.2.2.2 bouyer Fixed a problem where AcpiTerminate could fault if inadvertently called 1208 1.1.1.2.2.2 bouyer twice 1209 1.1.1.2.2.2 bouyer in succession. ACPICA BZ 795. 1210 1.1.1.2.2.2 bouyer 1211 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1212 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1213 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 1214 1.1.1.2.2.2 bouyer a 1215 1.1.1.2.2.2 bouyer much larger code and data size. 1216 1.1.1.2.2.2 bouyer 1217 1.1.1.2.2.2 bouyer Previous Release: 1218 1.1.1.2.2.2 bouyer Non-Debug Version: 84.7K Code, 17.8K Data, 102.5K Total 1219 1.1.1.2.2.2 bouyer Debug Version: 160.5K Code, 50.6K Data, 211.1K Total 1220 1.1.1.2.2.2 bouyer Current Release: 1221 1.1.1.2.2.2 bouyer Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total 1222 1.1.1.2.2.2 bouyer Debug Version: 161.6K Code, 50.9K Data, 212.5K Total 1223 1.1.1.2.2.2 bouyer 1224 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 1225 1.1.1.2.2.2 bouyer 1226 1.1.1.2.2.2 bouyer ACPI 4.0: Implemented disassembler support for all new ACPI tables and 1227 1.1.1.2.2.2 bouyer changes to existing tables. ACPICA BZ 775. 1228 1.1.1.2.2.2 bouyer 1229 1.1.1.2.2.2 bouyer ---------------------------------------- 1230 1.1.1.2.2.2 bouyer 25 June 2009. Summary of changes for version 20090625: 1231 1.1.1.2.2.2 bouyer 1232 1.1.1.2.2.2 bouyer The ACPI 4.0 Specification was released on June 16 and is available at 1233 1.1.1.2.2.2 bouyer www.acpi.info. ACPICA implementation of ACPI 4.0 is underway and will 1234 1.1.1.2.2.2 bouyer continue for the next few releases. 1235 1.1.1.2.2.2 bouyer 1236 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1237 1.1.1.2.2.2 bouyer 1238 1.1.1.2.2.2 bouyer ACPI 4.0: Implemented interpreter support for the IPMI operation region 1239 1.1.1.2.2.2 bouyer address space. Includes support for bi-directional data buffers and an IPMI 1240 1.1.1.2.2.2 bouyer address space handler (to be installed by an IPMI device driver.) ACPICA BZ 1241 1.1.1.2.2.2 bouyer 773. Lin Ming. 1242 1.1.1.2.2.2 bouyer 1243 1.1.1.2.2.2 bouyer ACPI 4.0: Added changes for existing ACPI tables - FACS and SRAT. Includes 1244 1.1.1.2.2.2 bouyer support in both the header files and the disassembler. 1245 1.1.1.2.2.2 bouyer 1246 1.1.1.2.2.2 bouyer Completed a major update for the AcpiGetObjectInfo external interface. 1247 1.1.1.2.2.2 bouyer Changes include: 1248 1.1.1.2.2.2 bouyer - Support for variable, unlimited length HID, UID, and CID strings. 1249 1.1.1.2.2.2 bouyer - Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.) 1250 1.1.1.2.2.2 bouyer - Call the _SxW power methods on behalf of a device object. 1251 1.1.1.2.2.2 bouyer - Determine if a device is a PCI root bridge. 1252 1.1.1.2.2.2 bouyer - Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO. 1253 1.1.1.2.2.2 bouyer These changes will require an update to all callers of this interface. See 1254 1.1.1.2.2.2 bouyer the updated ACPICA Programmer Reference for details. One new source file has 1255 1.1.1.2.2.2 bouyer been added - utilities/utids.c. ACPICA BZ 368, 780. 1256 1.1.1.2.2.2 bouyer 1257 1.1.1.2.2.2 bouyer Updated the AcpiRead and AcpiWrite external interfaces to support 64-bit 1258 1.1.1.2.2.2 bouyer transfers. The Value parameter has been extended from 32 bits to 64 bits in 1259 1.1.1.2.2.2 bouyer order to support new ACPI 4.0 tables. These changes will require an update 1260 1.1.1.2.2.2 bouyer to 1261 1.1.1.2.2.2 bouyer all callers of these interfaces. See the ACPICA Programmer Reference for 1262 1.1.1.2.2.2 bouyer details. ACPICA BZ 768. 1263 1.1.1.2.2.2 bouyer 1264 1.1.1.2.2.2 bouyer Fixed several problems with AcpiAttachData. The handler was not invoked when 1265 1.1.1.2.2.2 bouyer the host node was deleted. The data sub-object was not automatically deleted 1266 1.1.1.2.2.2 bouyer when the host node was deleted. The interface to the handler had an unused 1267 1.1.1.2.2.2 bouyer parameter, this was removed. ACPICA BZ 778. 1268 1.1.1.2.2.2 bouyer 1269 1.1.1.2.2.2 bouyer Enhanced the function that dumps ACPI table headers. All non-printable 1270 1.1.1.2.2.2 bouyer characters in the string fields are now replaced with '?' (Signature, OemId, 1271 1.1.1.2.2.2 bouyer OemTableId, and CompilerId.) ACPI tables with non-printable characters in 1272 1.1.1.2.2.2 bouyer these fields are occasionally seen in the field. ACPICA BZ 788. 1273 1.1.1.2.2.2 bouyer 1274 1.1.1.2.2.2 bouyer Fixed a problem with predefined method repair code where the code that 1275 1.1.1.2.2.2 bouyer attempts to repair/convert an object of incorrect type is only executed on 1276 1.1.1.2.2.2 bouyer the first time the predefined method is called. The mechanism that disables 1277 1.1.1.2.2.2 bouyer warnings on subsequent calls was interfering with the repair mechanism. 1278 1.1.1.2.2.2 bouyer ACPICA BZ 781. 1279 1.1.1.2.2.2 bouyer 1280 1.1.1.2.2.2 bouyer Fixed a possible memory leak in the predefined validation/repair code when a 1281 1.1.1.2.2.2 bouyer buffer is automatically converted to an expected string object. 1282 1.1.1.2.2.2 bouyer 1283 1.1.1.2.2.2 bouyer Removed obsolete 16-bit files from the distribution and from the current git 1284 1.1.1.2.2.2 bouyer tree head. ACPICA BZ 776. 1285 1.1.1.2.2.2 bouyer 1286 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1287 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20090521: 1309 1.1.1.2.2.2 bouyer 1310 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1311 1.1.1.2.2.2 bouyer 1312 1.1.1.2.2.2 bouyer Disabled the preservation of the SCI enable bit in the PM1 control register. 1313 1.1.1.2.2.2 bouyer The SCI enable bit (bit 0, SCI_EN) is defined by the ACPI specification to 1314 1.1.1.2.2.2 bouyer be 1315 1.1.1.2.2.2 bouyer a "preserved" bit - "OSPM always preserves this bit position", section 1316 1.1.1.2.2.2 bouyer 4.7.3.2.1. However, some machines fail if this bit is in fact preserved 1317 1.1.1.2.2.2 bouyer because the bit needs to be explicitly set by the OS as a workaround. No 1318 1.1.1.2.2.2 bouyer machines fail if the bit is not preserved. Therefore, ACPICA no longer 1319 1.1.1.2.2.2 bouyer attempts to preserve this bit. 1320 1.1.1.2.2.2 bouyer 1321 1.1.1.2.2.2 bouyer Fixed a problem in AcpiRsGetPciRoutingTableLength where an invalid or 1322 1.1.1.2.2.2 bouyer incorrectly formed _PRT package could cause a fault. Added validation to 1323 1.1.1.2.2.2 bouyer ensure that each package element is actually a sub-package. 1324 1.1.1.2.2.2 bouyer 1325 1.1.1.2.2.2 bouyer Implemented a new interface to install or override a single control method, 1326 1.1.1.2.2.2 bouyer AcpiInstallMethod. This interface is useful when debugging in order to 1327 1.1.1.2.2.2 bouyer repair 1328 1.1.1.2.2.2 bouyer an existing method or to install a missing method without having to override 1329 1.1.1.2.2.2 bouyer the entire ACPI table. See the ACPICA Programmer Reference for use and 1330 1.1.1.2.2.2 bouyer examples. Lin Ming, Bob Moore. 1331 1.1.1.2.2.2 bouyer 1332 1.1.1.2.2.2 bouyer Fixed several reference count issues with the DdbHandle object that is 1333 1.1.1.2.2.2 bouyer created from a Load or LoadTable operator. Prevent premature deletion of the 1334 1.1.1.2.2.2 bouyer object. Also, mark the object as invalid once the table has been unloaded. 1335 1.1.1.2.2.2 bouyer This is needed because the handle itself may not be deleted after the table 1336 1.1.1.2.2.2 bouyer unload, depending on whether it has been stored in a named object by the 1337 1.1.1.2.2.2 bouyer caller. Lin Ming. 1338 1.1.1.2.2.2 bouyer 1339 1.1.1.2.2.2 bouyer Fixed a problem with Mutex Sync Levels. Fixed a problem where if multiple 1340 1.1.1.2.2.2 bouyer mutexes of the same sync level are acquired but then not released in strict 1341 1.1.1.2.2.2 bouyer opposite order, the internally maintained Current Sync Level becomes 1342 1.1.1.2.2.2 bouyer confused 1343 1.1.1.2.2.2 bouyer and can cause subsequent execution errors. ACPICA BZ 471. 1344 1.1.1.2.2.2 bouyer 1345 1.1.1.2.2.2 bouyer Changed the allowable release order for ASL mutex objects. The ACPI 4.0 1346 1.1.1.2.2.2 bouyer specification has been changed to make the SyncLevel for mutex objects more 1347 1.1.1.2.2.2 bouyer useful. When releasing a mutex, the SyncLevel of the mutex must now be the 1348 1.1.1.2.2.2 bouyer same as the current sync level. This makes more sense than the previous rule 1349 1.1.1.2.2.2 bouyer (SyncLevel less than or equal). This change updates the code to match the 1350 1.1.1.2.2.2 bouyer specification. 1351 1.1.1.2.2.2 bouyer 1352 1.1.1.2.2.2 bouyer Fixed a problem with the local version of the AcpiOsPurgeCache function. The 1353 1.1.1.2.2.2 bouyer (local) cache must be locked during all cache object deletions. Andrew 1354 1.1.1.2.2.2 bouyer Baumann. 1355 1.1.1.2.2.2 bouyer 1356 1.1.1.2.2.2 bouyer Updated the Load operator to use operation region interfaces. This replaces 1357 1.1.1.2.2.2 bouyer direct memory mapping with region access calls. Now, all region accesses go 1358 1.1.1.2.2.2 bouyer through the installed region handler as they should. 1359 1.1.1.2.2.2 bouyer 1360 1.1.1.2.2.2 bouyer Simplified and optimized the NsGetNextNode function. Reduced parameter count 1361 1.1.1.2.2.2 bouyer and reduced code for this frequently used function. 1362 1.1.1.2.2.2 bouyer 1363 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1364 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1365 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 1366 1.1.1.2.2.2 bouyer a 1367 1.1.1.2.2.2 bouyer much larger code and data size. 1368 1.1.1.2.2.2 bouyer 1369 1.1.1.2.2.2 bouyer Previous Release: 1370 1.1.1.2.2.2 bouyer Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 1371 1.1.1.2.2.2 bouyer Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 1372 1.1.1.2.2.2 bouyer Current Release: 1373 1.1.1.2.2.2 bouyer Non-Debug Version: 83.4K Code, 17.5K Data, 100.9K Total 1374 1.1.1.2.2.2 bouyer Debug Version: 158.9K Code, 50.0K Data, 208.9K Total 1375 1.1.1.2.2.2 bouyer 1376 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 1377 1.1.1.2.2.2 bouyer 1378 1.1.1.2.2.2 bouyer Disassembler: Fixed some issues with DMAR, HEST, MADT tables. Some problems 1379 1.1.1.2.2.2 bouyer with sub-table disassembly and handling invalid sub-tables. Attempt recovery 1380 1.1.1.2.2.2 bouyer after an invalid sub-table ID. 1381 1.1.1.2.2.2 bouyer 1382 1.1.1.2.2.2 bouyer ---------------------------------------- 1383 1.1.1.2.2.2 bouyer 22 April 2009. Summary of changes for version 20090422: 1384 1.1.1.2.2.2 bouyer 1385 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1386 1.1.1.2.2.2 bouyer 1387 1.1.1.2.2.2 bouyer Fixed a compatibility issue with the recently released I/O port protection 1388 1.1.1.2.2.2 bouyer mechanism. For windows compatibility, 1) On a port protection violation, 1389 1.1.1.2.2.2 bouyer simply ignore the request and do not return an exception (allow the control 1390 1.1.1.2.2.2 bouyer method to continue execution.) 2) If only part of the request overlaps a 1391 1.1.1.2.2.2 bouyer protected port, read/write the individual ports that are not protected. 1392 1.1.1.2.2.2 bouyer Linux 1393 1.1.1.2.2.2 bouyer BZ 13036. Lin Ming 1394 1.1.1.2.2.2 bouyer 1395 1.1.1.2.2.2 bouyer Enhanced the execution of the ASL/AML BreakPoint operator so that it 1396 1.1.1.2.2.2 bouyer actually 1397 1.1.1.2.2.2 bouyer breaks into the AML debugger if the debugger is present. This matches the 1398 1.1.1.2.2.2 bouyer ACPI-defined behavior. 1399 1.1.1.2.2.2 bouyer 1400 1.1.1.2.2.2 bouyer Fixed several possible warnings related to the use of the configurable 1401 1.1.1.2.2.2 bouyer ACPI_THREAD_ID. This type can now be configured as either an integer or a 1402 1.1.1.2.2.2 bouyer pointer with no warnings. Also fixes several warnings in printf-like 1403 1.1.1.2.2.2 bouyer statements for the 64-bit build when the type is configured as a pointer. 1404 1.1.1.2.2.2 bouyer ACPICA BZ 766, 767. 1405 1.1.1.2.2.2 bouyer 1406 1.1.1.2.2.2 bouyer Fixed a number of possible warnings when compiling with gcc 4+ (depending on 1407 1.1.1.2.2.2 bouyer warning options.) Examples include printf formats, aliasing, unused globals, 1408 1.1.1.2.2.2 bouyer missing prototypes, missing switch default statements, use of non-ANSI 1409 1.1.1.2.2.2 bouyer library functions, use of non-ANSI constructs. See generate/unix/Makefile 1410 1.1.1.2.2.2 bouyer for 1411 1.1.1.2.2.2 bouyer a list of warning options used with gcc 3 and 4.

The 1415 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 1416 1.1.1.2.2.2 bouyer a 1417 1.1.1.2.2.2 bouyer much larger code and data size. 1418 1.1.1.2.2.2 bouyer 1419 1.1.1.2.2.2 bouyer Previous Release: 1420 1.1.1.2.2.2 bouyer Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 1421 1.1.1.2.2.2 bouyer Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 1422 1.1.1.2.2.2 bouyer Current Release: 1423 1.1.1.2.2.2 bouyer Non-Debug Version: 82.8K Code, 17.5K Data, 100.3K Total 1424 1.1.1.2.2.2 bouyer Debug Version: 158.0K Code, 49.9K Data, 207.9K Total 1425 1.1.1.2.2.2 bouyer 1426 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 1427 1.1.1.2.2.2 bouyer 1428 1.1.1.2.2.2 bouyer iASL: Fixed a generation warning from Bison 2.3 and fixed several warnings 1429 1.1.1.2.2.2 bouyer on 1430 1.1.1.2.2.2 bouyer the 64-bit build. 1431 1.1.1.2.2.2 bouyer 1432 1.1.1.2.2.2 bouyer iASL: Fixed a problem where the Unix/Linux versions of the compiler could 1433 1.1.1.2.2.2 bouyer not 1434 1.1.1.2.2.2 bouyer correctly digest Windows/DOS formatted files (with CR/LF). 1435 1.1.1.2.2.2 bouyer 1436 1.1.1.2.2.2 bouyer iASL: Added a new option for "quiet mode" (-va) that produces only the 1437 1.1.1.2.2.2 bouyer compilation summary, not individual errors and warnings. Useful for large 1438 1.1.1.2.2.2 bouyer batch compilations. 1439 1.1.1.2.2.2 bouyer 1440 1.1.1.2.2.2 bouyer AcpiExec: Implemented a new option (-z) to enable a forced semaphore/mutex 1441 1.1.1.2.2.2 bouyer timeout that can be used to detect hang conditions during execution of AML 1442 1.1.1.2.2.2 bouyer code (includes both internal semaphores and AML-defined mutexes and events.) 1443 1.1.1.2.2.2 bouyer 1444 1.1.1.2.2.2 bouyer Added new makefiles for the generation of acpica in a generic unix-like 1445 1.1.1.2.2.2 bouyer environment. These makefiles are intended to generate the acpica tools and 1446 1.1.1.2.2.2 bouyer utilities from the original acpica git source tree structure. 1447 1.1.1.2.2.2 bouyer 1448 1.1.1.2.2.2 bouyer Test Suites: Updated and cleaned up the documentation files. Updated the 1449 1.1.1.2.2.2 bouyer copyrights to 2009, affecting all source files. Use the new version of iASL 1450 1.1.1.2.2.2 bouyer with quiet mode. Increased the number of available semaphores in the Windows 1451 1.1.1.2.2.2 bouyer OSL, allowing the aslts to execute fully on Windows. For the Unix OSL, added 1452 1.1.1.2.2.2 bouyer an alternate implementation of the semaphore timeout to allow aslts to 1453 1.1.1.2.2.2 bouyer execute fully on Cygwin. 1454 1.1.1.2.2.2 bouyer 1455 1.1.1.2.2.2 bouyer ---------------------------------------- 1456 1.1.1.2.2.2 bouyer 20 March 2009. Summary of changes for version 20090320: 1457 1.1.1.2.2.2 bouyer 1458 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1459 1.1.1.2.2.2 bouyer 1460 1.1.1.2.2.2 bouyer Fixed a possible race condition between AcpiWalkNamespace and dynamic table 1461 1.1.1.2.2.2 bouyer unloads. Added a reader/writer locking mechanism to allow multiple 1462 1.1.1.2.2.2 bouyer concurrent 1463 1.1.1.2.2.2 bouyer namespace walks (readers), but block a dynamic table unload until it can 1464 1.1.1.2.2.2 bouyer gain 1465 1.1.1.2.2.2 bouyer exclusive write access to the namespace. This fixes a problem where a table 1466 1.1.1.2.2.2 bouyer unload could (possibly catastrophically) delete the portion of the namespace 1467 1.1.1.2.2.2 bouyer that is currently being examined by a walk. Adds a new file, utlock.c, that 1468 1.1.1.2.2.2 bouyer implements the reader/writer lock mechanism. ACPICA BZ 749. 1469 1.1.1.2.2.2 bouyer 1470 1.1.1.2.2.2 bouyer Fixed a regression introduced in version 20090220 where a change to the FADT 1471 1.1.1.2.2.2 bouyer handling could cause the ACPICA subsystem to access non-existent I/O ports. 1472 1.1.1.2.2.2 bouyer 1473 1.1.1.2.2.2 bouyer Modified the handling of FADT register and table (FACS/DSDT) addresses. The 1474 1.1.1.2.2.2 bouyer FADT can contain both 32-bit and 64-bit versions of these addresses. 1475 1.1.1.2.2.2 bouyer Previously, the 64-bit versions were favored, meaning that if both 32 and 64 1476 1.1.1.2.2.2 bouyer versions were valid, but not equal, the 64-bit version was used. This was 1477 1.1.1.2.2.2 bouyer found to cause some machines to fail. Now, in this case, the 32-bit version 1478 1.1.1.2.2.2 bouyer is used instead. This now matches the Windows behavior. 1479 1.1.1.2.2.2 bouyer 1480 1.1.1.2.2.2 bouyer Implemented a new mechanism to protect certain I/O ports. Provides Microsoft 1481 1.1.1.2.2.2 bouyer compatibility and protects the standard PC I/O ports from access via AML 1482 1.1.1.2.2.2 bouyer code. Adds a new file, hwvalid.c 1483 1.1.1.2.2.2 bouyer 1484 1.1.1.2.2.2 bouyer Fixed a possible extraneous warning message from the FADT support. The 1485 1.1.1.2.2.2 bouyer message warns of a 32/64 length mismatch between the legacy and GAS 1486 1.1.1.2.2.2 bouyer definitions for a register. 1487 1.1.1.2.2.2 bouyer 1488 1.1.1.2.2.2 bouyer Removed the obsolete AcpiOsValidateAddress OSL interface. This interface is 1489 1.1.1.2.2.2 bouyer made obsolete by the port protection mechanism above. It was previously used 1490 1.1.1.2.2.2 bouyer to validate the entire address range of an operation region, which could be 1491 1.1.1.2.2.2 bouyer incorrect if the range included illegal ports, but fields within the 1492 1.1.1.2.2.2 bouyer operation region did not actually access those ports. Validation is now 1493 1.1.1.2.2.2 bouyer performed on a per-field basis instead of the entire region. 1494 1.1.1.2.2.2 bouyer 1495 1.1.1.2.2.2 bouyer Modified the handling of the PM1 Status Register ignored bit (bit 11.) 1496 1.1.1.2.2.2 bouyer Ignored bits must be "preserved" according to the ACPI spec. Usually, this 1497 1.1.1.2.2.2 bouyer means a read/modify/write when writing to the register. However, for status 1498 1.1.1.2.2.2 bouyer registers, writing a one means clear the event. Writing a zero means 1499 1.1.1.2.2.2 bouyer preserve 1500 1.1.1.2.2.2 bouyer the event (do not clear.) This behavior is clarified in the ACPI 4.0 spec, 1501 1.1.1.2.2.2 bouyer and the ACPICA code now simply always writes a zero to the ignored bit. 1502 1.1.1.2.2.2 bouyer 1503 1.1.1.2.2.2 bouyer Modified the handling of ignored bits for the PM1 A/B Control Registers. As 1504 1.1.1.2.2.2 bouyer per the ACPI specification, for the control registers, preserve 1505 1.1.1.2.2.2 bouyer (read/modify/write) all bits that are defined as either reserved or ignored. 1506 1.1.1.2.2.2 bouyer 1507 1.1.1.2.2.2 bouyer Updated the handling of write-only bits in the PM1 A/B Control Registers. 1508 1.1.1.2.2.2 bouyer When reading the register, zero the write-only bits as per the ACPI spec. 1509 1.1.1.2.2.2 bouyer ACPICA BZ 443. Lin Ming. 1510 1.1.1.2.2.2 bouyer 1511 1.1.1.2.2.2 bouyer Removed "Linux" from the list of supported _OSI strings. Linux no longer 1512 1.1.1.2.2.2 bouyer wants to reply true to this request. The Windows strings are the only paths 1513 1.1.1.2.2.2 bouyer through the AML that are tested and known to work properly. 1514 1.1.1.2.2.2 bouyer 1515 1.1.1.2.2.2 bouyer Previous Release: 1516 1.1.1.2.2.2 bouyer Non-Debug Version: 82.0K Code, 17.5K Data, 99.5K Total 1517 1.1.1.2.2.2 bouyer Debug Version: 156.9K Code, 49.8K Data, 206.7K Total 1518 1.1.1.2.2.2 bouyer Current Release: 1519 1.1.1.2.2.2 bouyer Non-Debug Version: 82.6K Code, 17.6K Data, 100.2K Total 1520 1.1.1.2.2.2 bouyer Debug Version: 157.7K Code, 49.9K Data, 207.6K Total 1521 1.1.1.2.2.2 bouyer 1522 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 1523 1.1.1.2.2.2 bouyer 1524 1.1.1.2.2.2 bouyer Acpiexec: Split the large aeexec.c file into two new files, aehandlers.c and 1525 1.1.1.2.2.2 bouyer aetables.c 1526 1.1.1.2.2.2 bouyer 1527 1.1.1.2.2.2 bouyer ---------------------------------------- 1528 1.1.1.2.2.2 bouyer 20 February 2009. Summary of changes for version 20090220: 1529 1.1.1.2.2.2 bouyer 1530 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1531 1.1.1.2.2.2 bouyer 1532 1.1.1.2.2.2 bouyer Optimized the ACPI register locking. Removed locking for reads from the ACPI 1533 1.1.1.2.2.2 bouyer bit registers in PM1 Status, Enable, Control, and PM2 Control. The lock is 1534 1.1.1.2.2.2 bouyer not required when reading the single-bit registers. The 1535 1.1.1.2.2.2 bouyer AcpiGetRegisterUnlocked function is no longer needed and has been removed. 1536 1.1.1.2.2.2 bouyer This will improve performance for reads on these registers. ACPICA BZ 760. 1537 1.1.1.2.2.2 bouyer 1538 1.1.1.2.2.2 bouyer Fixed the parameter validation for AcpiRead/Write. Now return 1539 1.1.1.2.2.2 bouyer AE_BAD_PARAMETER if the input register pointer is null, and AE_BAD_ADDRESS 1540 1.1.1.2.2.2 bouyer if 1541 1.1.1.2.2.2 bouyer the register has an address of zero. Previously, these cases simply returned 1542 1.1.1.2.2.2 bouyer AE_OK. For optional registers such as PM1B status/enable/control, the caller 1543 1.1.1.2.2.2 bouyer should check for a valid register address before calling. ACPICA BZ 748. 1544 1.1.1.2.2.2 bouyer 1545 1.1.1.2.2.2 bouyer Renamed the external ACPI bit register access functions. Renamed 1546 1.1.1.2.2.2 bouyer AcpiGetRegister and AcpiSetRegister to clarify the purpose of these 1547 1.1.1.2.2.2 bouyer functions. The new names are AcpiReadBitRegister and AcpiWriteBitRegister. 1548 1.1.1.2.2.2 bouyer Also, restructured the code for these functions by simplifying the code path 1549 1.1.1.2.2.2 bouyer and condensing duplicate code to reduce code size. 1550 1.1.1.2.2.2 bouyer 1551 1.1.1.2.2.2 bouyer Added new functions to transparently handle the possibly split PM1 A/B 1552 1.1.1.2.2.2 bouyer registers. AcpiHwReadMultiple and AcpiHwWriteMultiple. These two functions 1553 1.1.1.2.2.2 bouyer now handle the split registers for PM1 Status, Enable, and Control. ACPICA 1554 1.1.1.2.2.2 bouyer BZ 1555 1.1.1.2.2.2 bouyer 746. 1556 1.1.1.2.2.2 bouyer 1557 1.1.1.2.2.2 bouyer Added a function to handle the PM1 control registers, AcpiHwWritePm1Control. 1558 1.1.1.2.2.2 bouyer This function writes both of the PM1 control registers (A/B). These 1559 1.1.1.2.2.2 bouyer registers 1560 1.1.1.2.2.2 bouyer are different than the PM1 A/B status and enable registers in that different 1561 1.1.1.2.2.2 bouyer values can be written to the A/B registers. Most notably, the SLP_TYP bits 1562 1.1.1.2.2.2 bouyer can be different, as per the values returned from the _Sx predefined 1563 1.1.1.2.2.2 bouyer methods. 1564 1.1.1.2.2.2 bouyer 1565 1.1.1.2.2.2 bouyer Removed an extra register write within AcpiHwClearAcpiStatus. This function 1566 1.1.1.2.2.2 bouyer was writing an optional PM1B status register twice. The existing call to the 1567 1.1.1.2.2.2 bouyer low-level AcpiHwRegisterWrite automatically handles a possibly split PM1 A/B 1568 1.1.1.2.2.2 bouyer register. ACPICA BZ 751. 1569 1.1.1.2.2.2 bouyer 1570 1.1.1.2.2.2 bouyer Split out the PM1 Status registers from the FADT. Added new globals for 1571 1.1.1.2.2.2 bouyer these 1572 1.1.1.2.2.2 bouyer registers (A/B), similar to the way the PM1 Enable registers are handled. 1573 1.1.1.2.2.2 bouyer Instead of overloading the FADT Event Register blocks. This makes the code 1574 1.1.1.2.2.2 bouyer clearer and less prone to error. 1575 1.1.1.2.2.2 bouyer 1576 1.1.1.2.2.2 bouyer Fixed the warning message for when the platform contains too many ACPI 1577 1.1.1.2.2.2 bouyer tables 1578 1.1.1.2.2.2 bouyer for the default size of the global root table data structure. The 1579 1.1.1.2.2.2 bouyer calculation 1580 1.1.1.2.2.2 bouyer for the truncation value was incorrect. 1581 1.1.1.2.2.2 bouyer 1582 1.1.1.2.2.2 bouyer Removed the ACPI_GET_OBJECT_TYPE macro. Removed all instances of this 1583 1.1.1.2.2.2 bouyer obsolete macro, since it is now a simple reference to ->common.type. There 1584 1.1.1.2.2.2 bouyer were about 150 invocations of the macro across 41 files. ACPICA BZ 755. 1585 1.1.1.2.2.2 bouyer 1586 1.1.1.2.2.2 bouyer Removed the redundant ACPI_BITREG_SLEEP_TYPE_B. This type is the same as 1587 1.1.1.2.2.2 bouyer TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to 1588 1.1.1.2.2.2 bouyer simply SLEEP_TYPE. ACPICA BZ 754. 1589 1.1.1.2.2.2 bouyer 1590 1.1.1.2.2.2 bouyer Conditionally compile the AcpiSetFirmwareWakingVector64 function. This 1591 1.1.1.2.2.2 bouyer function is only needed on 64-bit host operating systems and is thus not 1592 1.1.1.2.2.2 bouyer included for 32-bit hosts. 1593 1.1.1.2.2.2 bouyer 1594 1.1.1.2.2.2 bouyer Debug output: print the input and result for invocations of the _OSI 1595 1.1.1.2.2.2 bouyer reserved 1596 1.1.1.2.2.2 bouyer control method via the ACPI_LV_INFO debug level. Also, reduced some of the 1597 1.1.1.2.2.2 bouyer verbosity of this debug level.

Summary of changes for version 20090123: 1619 1.1.1.2.2.2 bouyer 1620 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1621 1.1.1.2.2.2 bouyer 1622 1.1.1.2.2.2 bouyer Added the 2009 copyright to all module headers and signons. This affects 1623 1.1.1.2.2.2 bouyer virtually every file in the ACPICA core subsystem, the iASL compiler, and 1624 1.1.1.2.2.2 bouyer the tools/utilities. 1625 1.1.1.2.2.2 bouyer 1626 1.1.1.2.2.2 bouyer Implemented a change to allow the host to override any ACPI table, including 1627 1.1.1.2.2.2 bouyer dynamically loaded tables. Previously, only the DSDT could be replaced by 1628 1.1.1.2.2.2 bouyer the 1629 1.1.1.2.2.2 bouyer host. With this change, the AcpiOsTableOverride interface is called for each 1630 1.1.1.2.2.2 bouyer table found in the RSDT/XSDT during ACPICA initialization, and also whenever 1631 1.1.1.2.2.2 bouyer a table is dynamically loaded via the AML Load operator. 1632 1.1.1.2.2.2 bouyer 1633 1.1.1.2.2.2 bouyer Updated FADT flag definitions, especially the Boot Architecture flags. 1634 1.1.1.2.2.2 bouyer 1635 1.1.1.2.2.2 bouyer Debugger: For the Find command, automatically pad the input ACPI name with 1636 1.1.1.2.2.2 bouyer underscores if the name is shorter than 4 characters. This enables a match 1637 1.1.1.2.2.2 bouyer with the actual namespace entry which is itself padded with underscores. 1638 1.1.1.2.2.2 bouyer 1639 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1640 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20081204: 1665 1.1.1.2.2.2 bouyer 1666 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1667 1.1.1.2.2.2 bouyer 1668 1.1.1.2.2.2 bouyer The ACPICA Programmer Reference has been completely updated and revamped for 1669 1.1.1.2.2.2 bouyer this release. This includes updates to the external interfaces, OSL 1670 1.1.1.2.2.2 bouyer interfaces, the overview sections, and the debugger reference. 1671 1.1.1.2.2.2 bouyer 1672 1.1.1.2.2.2 bouyer Several new ACPICA interfaces have been implemented and documented in the 1673 1.1.1.2.2.2 bouyer programmer reference: 1674 1.1.1.2.2.2 bouyer AcpiReset - Writes the reset value to the FADT-defined reset register. 1675 1.1.1.2.2.2 bouyer AcpiDisableAllGpes - Disable all available GPEs. 1676 1.1.1.2.2.2 bouyer AcpiEnableAllRuntimeGpes - Enable all available runtime GPEs. 1677 1.1.1.2.2.2 bouyer AcpiGetGpeDevice - Get the GPE block device associated with a GPE. 1678 1.1.1.2.2.2 bouyer AcpiGbl_CurrentGpeCount - Tracks the current number of available GPEs. 1679 1.1.1.2.2.2 bouyer AcpiRead - Low-level read ACPI register (was HwLowLevelRead.) 1680 1.1.1.2.2.2 bouyer AcpiWrite - Low-level write ACPI register (was HwLowLevelWrite.) 1681 1.1.1.2.2.2 bouyer 1682 1.1.1.2.2.2 bouyer Most of the public ACPI hardware-related interfaces have been moved to a new 1683 1.1.1.2.2.2 bouyer file, components/hardware/hwxface.c 1684 1.1.1.2.2.2 bouyer 1685 1.1.1.2.2.2 bouyer Enhanced the FADT parsing and low-level ACPI register access: The ACPI 1686 1.1.1.2.2.2 bouyer register lengths within the FADT are now used, and the low level ACPI 1687 1.1.1.2.2.2 bouyer register access no longer hardcodes the ACPI register lengths. Given that 1688 1.1.1.2.2.2 bouyer there may be some risk in actually trusting the FADT register lengths, a 1689 1.1.1.2.2.2 bouyer run- 1690 1.1.1.2.2.2 bouyer time option was added to fall back to the default hardcoded lengths if the 1691 1.1.1.2.2.2 bouyer FADT proves to contain incorrect values - UseDefaultRegisterWidths. This 1692 1.1.1.2.2.2 bouyer option is set to true for now, and a warning is issued if a suspicious FADT 1693 1.1.1.2.2.2 bouyer register length is overridden with the default value. 1694 1.1.1.2.2.2 bouyer 1695 1.1.1.2.2.2 bouyer Fixed a reference count issue in NsRepairObject. This problem was introduced 1696 1.1.1.2.2.2 bouyer in version 20081031 as part of a fix to repair Buffer objects within 1697 1.1.1.2.2.2 bouyer Packages. Lin Ming. 1698 1.1.1.2.2.2 bouyer 1699 1.1.1.2.2.2 bouyer Added semaphore support to the Linux/Unix application OS-services layer 1700 1.1.1.2.2.2 bouyer (OSL). ACPICA BZ 448. Lin Ming. 1701 1.1.1.2.2.2 bouyer 1702 1.1.1.2.2.2 bouyer Added the ACPI_MUTEX_TYPE configuration option to select whether mutexes 1703 1.1.1.2.2.2 bouyer will 1704 1.1.1.2.2.2 bouyer be implemented in the OSL, or will binary semaphores be used instead. 1705 1.1.1.2.2.2 bouyer 1706 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1707 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20081031: 1736 1.1.1.2.2.2 bouyer 1737 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1738 1.1.1.2.2.2 bouyer 1739 1.1.1.2.2.2 bouyer Restructured the ACPICA header files into public/private. acpi.h now 1740 1.1.1.2.2.2 bouyer includes 1741 1.1.1.2.2.2 bouyer only the "public" acpica headers. All other acpica headers are "private" and 1742 1.1.1.2.2.2 bouyer should not be included by acpica users. One new file, accommon.h is used to 1743 1.1.1.2.2.2 bouyer include the commonly used private headers for acpica code generation. Future 1744 1.1.1.2.2.2 bouyer plans include moving all private headers to a new subdirectory. 1745 1.1.1.2.2.2 bouyer 1746 1.1.1.2.2.2 bouyer Implemented an automatic Buffer->String return value conversion for 1747 1.1.1.2.2.2 bouyer predefined ACPI methods. For these methods (such as _BIF), added automatic 1748 1.1.1.2.2.2 bouyer conversion for return objects that are required to be a String, but a Buffer 1749 1.1.1.2.2.2 bouyer was found instead. This can happen when reading string battery data from an 1750 1.1.1.2.2.2 bouyer operation region, because it used to be difficult to convert the data from 1751 1.1.1.2.2.2 bouyer buffer to string from within the ASL. Ensures that the host OS is provided 1752 1.1.1.2.2.2 bouyer with a valid null-terminated string. Linux BZ 11822. 1753 1.1.1.2.2.2 bouyer 1754 1.1.1.2.2.2 bouyer Updated the FACS waking vector interfaces. Split AcpiSetFirmwareWakingVector 1755 1.1.1.2.2.2 bouyer into two: one for the 32-bit vector, another for the 64-bit vector. This is 1756 1.1.1.2.2.2 bouyer required because the host OS must setup the wake much differently for each 1757 1.1.1.2.2.2 bouyer vector (real vs. protected mode, etc.) and the interface itself should not 1758 1.1.1.2.2.2 bouyer be 1759 1.1.1.2.2.2 bouyer deciding which vector to use. Also, eliminated the GetFirmwareWakingVector 1760 1.1.1.2.2.2 bouyer interface, as it served no purpose (only the firmware reads the vector, OS 1761 1.1.1.2.2.2 bouyer only writes the vector.) ACPICA BZ 731. 1762 1.1.1.2.2.2 bouyer 1763 1.1.1.2.2.2 bouyer Implemented a mechanism to escape infinite AML While() loops. Added a loop 1764 1.1.1.2.2.2 bouyer counter to force exit from AML While loops if the count becomes too large. 1765 1.1.1.2.2.2 bouyer This can occur in poorly written AML when the hardware does not respond 1766 1.1.1.2.2.2 bouyer within a while loop and the loop does not implement a timeout. The maximum 1767 1.1.1.2.2.2 bouyer loop count is configurable. A new exception code is returned when a loop is 1768 1.1.1.2.2.2 bouyer broken, AE_AML_INFINITE_LOOP. Alexey Starikovskiy, Bob Moore. 1769 1.1.1.2.2.2 bouyer 1770 1.1.1.2.2.2 bouyer Optimized the execution of AML While loops. Previously, a control state 1771 1.1.1.2.2.2 bouyer object was allocated and freed for each execution of the loop. The 1772 1.1.1.2.2.2 bouyer optimization is to simply reuse the control state for each iteration. This 1773 1.1.1.2.2.2 bouyer speeds up the raw loop execution time by about 5%. 1774 1.1.1.2.2.2 bouyer 1775 1.1.1.2.2.2 bouyer Enhanced the implicit return mechanism. For Windows compatibility, return an 1776 1.1.1.2.2.2 bouyer implicit integer of value zero for methods that contain no executable code. 1777 1.1.1.2.2.2 bouyer Such methods are seen in the field as stubs (presumably), and can cause 1778 1.1.1.2.2.2 bouyer drivers to fail if they expect a return value. Lin Ming. 1779 1.1.1.2.2.2 bouyer 1780 1.1.1.2.2.2 bouyer Allow multiple backslashes as root prefixes in namepaths. In a fully 1781 1.1.1.2.2.2 bouyer qualified namepath, allow multiple backslash prefixes. This can happen (and 1782 1.1.1.2.2.2 bouyer is seen in the field) because of the use of a double-backslash in strings 1783 1.1.1.2.2.2 bouyer (since backslash is the escape character) causing confusion. ACPICA BZ 739 1784 1.1.1.2.2.2 bouyer Lin Ming. 1785 1.1.1.2.2.2 bouyer 1786 1.1.1.2.2.2 bouyer Emit a warning if two different FACS or DSDT tables are discovered in the 1787 1.1.1.2.2.2 bouyer FADT. Checks if there are two valid but different addresses for the FACS and 1788 1.1.1.2.2.2 bouyer DSDT within the FADT (mismatch between the 32-bit and 64-bit fields.) 1789 1.1.1.2.2.2 bouyer 1790 1.1.1.2.2.2 bouyer Consolidated the method argument count validation code. Merged the code that 1791 1.1.1.2.2.2 bouyer validates control method argument counts into the predefined validation 1792 1.1.1.2.2.2 bouyer module. Eliminates possible multiple warnings for incorrect argument counts. 1793 1.1.1.2.2.2 bouyer 1794 1.1.1.2.2.2 bouyer Implemented ACPICA example code. Includes code for ACPICA initialization, 1795 1.1.1.2.2.2 bouyer handler installation, and calling a control method. Available at 1796 1.1.1.2.2.2 bouyer source/tools/examples. 1797 1.1.1.2.2.2 bouyer 1798 1.1.1.2.2.2 bouyer Added a global pointer for FACS table to simplify internal FACS access. Use 1799 1.1.1.2.2.2 bouyer the global pointer instead of using AcpiGetTableByIndex for each FACS 1800 1.1.1.2.2.2 bouyer access. 1801 1.1.1.2.2.2 bouyer This simplifies the code for the Global Lock and the Firmware Waking 1802 1.1.1.2.2.2 bouyer Vector(s). 1803 1.1.1.2.2.2 bouyer 1804 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1805 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

ACPICA BZ 738. 1834 1.1.1.2.2.2 bouyer 1835 1.1.1.2.2.2 bouyer ---------------------------------------- 1836 1.1.1.2.2.2 bouyer 26 September 2008. Summary of changes for version 20080926: 1837 1.1.1.2.2.2 bouyer 1838 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1839 1.1.1.2.2.2 bouyer 1840 1.1.1.2.2.2 bouyer Designed and implemented a mechanism to validate predefined ACPI methods and 1841 1.1.1.2.2.2 bouyer objects. This code validates the predefined ACPI objects (objects whose 1842 1.1.1.2.2.2 bouyer names 1843 1.1.1.2.2.2 bouyer start with underscore) that appear in the namespace, at the time they are 1844 1.1.1.2.2.2 bouyer evaluated. The argument count and the type of the returned object are 1845 1.1.1.2.2.2 bouyer validated against the ACPI specification. The purpose of this validation is 1846 1.1.1.2.2.2 bouyer to detect problems with the BIOS-implemented predefined ACPI objects before 1847 1.1.1.2.2.2 bouyer the results are returned to the ACPI-related drivers. Future enhancements 1848 1.1.1.2.2.2 bouyer may 1849 1.1.1.2.2.2 bouyer include actual repair of incorrect return objects where possible. Two new 1850 1.1.1.2.2.2 bouyer files are nspredef.c and acpredef.h. 1851 1.1.1.2.2.2 bouyer 1852 1.1.1.2.2.2 bouyer Fixed a fault in the AML parser if a memory allocation fails during the Op 1853 1.1.1.2.2.2 bouyer completion routine AcpiPsCompleteThisOp. Lin Ming. ACPICA BZ 492. 1854 1.1.1.2.2.2 bouyer 1855 1.1.1.2.2.2 bouyer Fixed an issue with implicit return compatibility. This change improves the 1856 1.1.1.2.2.2 bouyer implicit return mechanism to be more compatible with the MS interpreter. Lin 1857 1.1.1.2.2.2 bouyer Ming, ACPICA BZ 349. 1858 1.1.1.2.2.2 bouyer 1859 1.1.1.2.2.2 bouyer Implemented support for zero-length buffer-to-string conversions. Allow zero 1860 1.1.1.2.2.2 bouyer length strings during interpreter buffer-to-string conversions. For example, 1861 1.1.1.2.2.2 bouyer during the ToDecimalString and ToHexString operators, as well as implicit 1862 1.1.1.2.2.2 bouyer conversions. Fiodor Suietov, ACPICA BZ 585. 1863 1.1.1.2.2.2 bouyer 1864 1.1.1.2.2.2 bouyer Fixed two possible memory leaks in the error exit paths of 1865 1.1.1.2.2.2 bouyer AcpiUtUpdateObjectReference and AcpiUtWalkPackageTree. These functions are 1866 1.1.1.2.2.2 bouyer similar in that they use a stack of state objects in order to eliminate 1867 1.1.1.2.2.2 bouyer recursion. The stack must be fully unwound and deallocated if an error 1868 1.1.1.2.2.2 bouyer occurs. Lin Ming. ACPICA BZ 383. 1869 1.1.1.2.2.2 bouyer 1870 1.1.1.2.2.2 bouyer Removed the unused ACPI_BITREG_WAKE_ENABLE definition and entry in the 1871 1.1.1.2.2.2 bouyer global 1872 1.1.1.2.2.2 bouyer ACPI register table. This bit does not exist and is unused. Lin Ming, Bob 1873 1.1.1.2.2.2 bouyer Moore ACPICA BZ 442. 1874 1.1.1.2.2.2 bouyer 1875 1.1.1.2.2.2 bouyer Removed the obsolete version number in module headers. Removed the 1876 1.1.1.2.2.2 bouyer "$Revision" number that appeared in each module header. This version number 1877 1.1.1.2.2.2 bouyer was useful under SourceSafe and CVS, but has no meaning under git. It is not 1878 1.1.1.2.2.2 bouyer only incorrect, it could also be misleading. 1879 1.1.1.2.2.2 bouyer 1880 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 1881 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 1882 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 1883 1.1.1.2.2.2 bouyer a 1884 1.1.1.2.2.2 bouyer much larger code and data size. 1885 1.1.1.2.2.2 bouyer 1886 1.1.1.2.2.2 bouyer Previous Release: 1887 1.1.1.2.2.2 bouyer Non-Debug Version: 79.7K Code, 16.4K Data, 96.1K Total 1888 1.1.1.2.2.2 bouyer Debug Version: 153.7K Code, 48.2K Data, 201.9K Total 1889 1.1.1.2.2.2 bouyer Current Release: 1890 1.1.1.2.2.2 bouyer Non-Debug Version: 81.2K Code, 17.0K Data, 98.2K Total 1891 1.1.1.2.2.2 bouyer Debug Version: 155.8K Code, 49.1K Data, 204.9K Total 1892 1.1.1.2.2.2 bouyer 1893 1.1.1.2.2.2 bouyer ---------------------------------------- 1894 1.1.1.2.2.2 bouyer 29 August 2008. Summary of changes for version 20080829: 1895 1.1.1.2.2.2 bouyer 1896 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 1897 1.1.1.2.2.2 bouyer 1898 1.1.1.2.2.2 bouyer Completed a major cleanup of the internal ACPI_OPERAND_OBJECT of type 1899 1.1.1.2.2.2 bouyer Reference. Changes include the elimination of cheating on the Object field 1900 1.1.1.2.2.2 bouyer for the DdbHandle subtype, addition of a reference class field to 1901 1.1.1.2.2.2 bouyer differentiate the various reference types (instead of an AML opcode), and 1902 1.1.1.2.2.2 bouyer the 1903 1.1.1.2.2.2 bouyer cleanup of debug output for this object. Lin Ming, Bob Moore. BZ 723 1904 1.1.1.2.2.2 bouyer 1905 1.1.1.2.2.2 bouyer Reduce an error to a warning for an incorrect method argument count. 1906 1.1.1.2.2.2 bouyer Previously aborted with an error if too few arguments were passed to a 1907 1.1.1.2.2.2 bouyer control method via the external ACPICA interface. Now issue a warning 1908 1.1.1.2.2.2 bouyer instead 1909 1.1.1.2.2.2 bouyer and continue. Handles the case where the method inadvertently declares too 1910 1.1.1.2.2.2 bouyer many arguments, but does not actually use the extra ones. Applies mainly to 1911 1.1.1.2.2.2 bouyer the predefined methods. Lin Ming. Linux BZ 11032. 1912 1.1.1.2.2.2 bouyer 1913 1.1.1.2.2.2 bouyer Disallow the evaluation of named object types with no intrinsic value. 1914 1.1.1.2.2.2 bouyer Return 1915 1.1.1.2.2.2 bouyer AE_TYPE for objects that have no value and therefore evaluation is 1916 1.1.1.2.2.2 bouyer undefined: 1917 1.1.1.2.2.2 bouyer Device, Event, Mutex, Region, Thermal, and Scope. Previously, evaluation of 1918 1.1.1.2.2.2 bouyer these types were allowed, but an exception would be generated at some point 1919 1.1.1.2.2.2 bouyer during the evaluation. Now, the error is generated up front. 1920 1.1.1.2.2.2 bouyer 1921 1.1.1.2.2.2 bouyer Fixed a possible memory leak in the AcpiNsGetExternalPathname function 1922 1.1.1.2.2.2 bouyer (nsnames.c). Fixes a leak in the error exit path. 1923 1.1.1.2.2.2 bouyer 1924 1.1.1.2.2.2 bouyer Removed the obsolete debug levels ACPI_DB_WARN and ACPI_DB_ERROR. These 1925 1.1.1.2.2.2 bouyer debug 1926 1.1.1.2.2.2 bouyer levels were made obsolete by the ACPI_WARNING, ACPI_ERROR, and 1927 1.1.1.2.2.2 bouyer ACPI_EXCEPTION 1928 1.1.1.2.2.2 bouyer interfaces. Also added ACPI_DB_EVENTS to correspond with the existing 1929 1.1.1.2.2.2 bouyer ACPI_LV_EVENTS. 1930 1.1.1.2.2.2 bouyer 1931 1.1.1.2.2.2 bouyer Removed obsolete and/or unused exception codes from the acexcep.h header. 1932 1.1.1.2.2.2 bouyer There is the possibility that certain device drivers may be affected if they 1933 1.1.1.2.2.2 bouyer use any of these exceptions. 1934 1.1.1.2.2.2 bouyer 1935 1.1.1.2.2.2 bouyer The ACPICA documentation has been added to the public git source tree, under 1936 1.1.1.2.2.2 bouyer acpica/documents.

ACPI 3.0 1955 1.1.1.2.2.2 bouyer defines _SCP with 3 arguments. Previous versions defined it with only 1 1956 1.1.1.2.2.2 bouyer argument. iASL now allows both definitions. 1957 1.1.1.2.2.2 bouyer 1958 1.1.1.2.2.2 bouyer iASL/disassembler: avoid infinite loop on bad ACPI tables. Check for zero- 1959 1.1.1.2.2.2 bouyer length subtables when disassembling ACPI tables. Also fixed a couple of 1960 1.1.1.2.2.2 bouyer errors where a full 16-bit table type field was not extracted from the input 1961 1.1.1.2.2.2 bouyer properly. 1962 1.1.1.2.2.2 bouyer 1963 1.1.1.2.2.2 bouyer acpisrc: Improve comment counting mechanism for generating source code 1964 1.1.1.2.2.2 bouyer statistics.

Remove call to 1975 1.1.1.2.2.2 bouyer AcpiHwDisableAllGpes during wake in AcpiEvGpeDispatch. This call will 1976 1.1.1.2.2.2 bouyer attempt 1977 1.1.1.2.2.2 bouyer to acquire the GPE lock but can deadlock since the GPE lock is already held 1978 1.1.1.2.2.2 bouyer at dispatch time. This code was introduced in version 20060831 as a response 1979 1.1.1.2.2.2 bouyer to Linux BZ 6881 and has since been removed from Linux. 1980 1.1.1.2.2.2 bouyer 1981 1.1.1.2.2.2 bouyer Add a function to dereference returned reference objects. Examines the 1982 1.1.1.2.2.2 bouyer return 1983 1.1.1.2.2.2 bouyer object from a call to AcpiEvaluateObject. Any Index or RefOf references are 1984 1.1.1.2.2.2 bouyer automatically dereferenced in an attempt to return something useful (these 1985 1.1.1.2.2.2 bouyer reference types cannot be converted into an external ACPI_OBJECT.)

Now performs a read-change-write of the enable register instead 2080 1.1.1.2.2.2 bouyer of simply writing out the cached enable mask. This will prevent inadvertent 2081 1.1.1.2.2.2 bouyer enabling of GPEs if a rogue GPE is received during initialization (before 2082 1.1.1.2.2.2 bouyer GPE 2083 1.1.1.2.2.2 bouyer handlers are installed.) 2084 1.1.1.2.2.2 bouyer 2085 1.1.1.2.2.2 bouyer Implemented a copy for dynamically loaded tables. Previously, dynamically 2086 1.1.1.2.2.2 bouyer loaded tables were simply mapped - but on some machines this memory is 2087 1.1.1.2.2.2 bouyer corrupted after suspend. Now copy the table to a local buffer. For the 2088 1.1.1.2.2.2 bouyer OpRegion case, added checksum verify. Use the table length from the table 2089 1.1.1.2.2.2 bouyer header, not the region length. For the Buffer case, use the table length 2090 1.1.1.2.2.2 bouyer also. Dennis Noordsij, Bob Moore. BZ 10734 2091 1.1.1.2.2.2 bouyer 2092 1.1.1.2.2.2 bouyer Fixed a problem where the same ACPI table could not be dynamically loaded 2093 1.1.1.2.2.2 bouyer and 2094 1.1.1.2.2.2 bouyer unloaded more than once. Without this change, a table cannot be loaded again 2095 1.1.1.2.2.2 bouyer once it has been loaded/unloaded one time. The current mechanism does not 2096 1.1.1.2.2.2 bouyer unregister a table upon an unload. During a load, if the same table is 2097 1.1.1.2.2.2 bouyer found, 2098 1.1.1.2.2.2 bouyer this no longer returns an exception. BZ 722 2099 1.1.1.2.2.2 bouyer 2100 1.1.1.2.2.2 bouyer Fixed a problem where the wrong descriptor length was calculated for the 2101 1.1.1.2.2.2 bouyer EndTag descriptor in 64-bit mode. The "minimal" descriptors such as EndTag 2102 1.1.1.2.2.2 bouyer are calculated as 12 bytes long, but the actual length in the internal 2103 1.1.1.2.2.2 bouyer descriptor is 16 because of the round-up to 8 on the 64-bit build. Reported 2104 1.1.1.2.2.2 bouyer by Linn Crosetto. BZ 728 2105 1.1.1.2.2.2 bouyer 2106 1.1.1.2.2.2 bouyer Fixed a possible memory leak in the Unload operator. The DdbHandle returned 2107 1.1.1.2.2.2 bouyer by Load() did not have its reference count decremented during unload, 2108 1.1.1.2.2.2 bouyer leading 2109 1.1.1.2.2.2 bouyer to a memory leak. Lin Ming. BZ 727 2110 1.1.1.2.2.2 bouyer 2111 1.1.1.2.2.2 bouyer Fixed a possible memory leak when deleting thermal/processor objects.

BZ 506 2114 1.1.1.2.2.2 bouyer 2115 1.1.1.2.2.2 bouyer Fixed the ordering of the ASCII names in the global mutex table to match the 2116 1.1.1.2.2.2 bouyer actual mutex IDs. Used by AcpiUtGetMutexName, a function used for debug 2117 1.1.1.2.2.2 bouyer only. 2118 1.1.1.2.2.2 bouyer Vegard Nossum. BZ 726 2119 1.1.1.2.2.2 bouyer 2120 1.1.1.2.2.2 bouyer Enhanced the AcpiGetObjectInfo interface to return the number of required 2121 1.1.1.2.2.2 bouyer arguments if the object is a control method. Added this call to the debugger 2122 1.1.1.2.2.2 bouyer so the proper number of default arguments are passed to a method. This 2123 1.1.1.2.2.2 bouyer prevents a warning when executing methods from AcpiExec. 2124 1.1.1.2.2.2 bouyer 2125 1.1.1.2.2.2 bouyer Added a check for an invalid handle in AcpiGetObjectInfo.

Summary of changes for version 20080609: 2170 1.1.1.2.2.2 bouyer 2171 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2172 1.1.1.2.2.2 bouyer 2173 1.1.1.2.2.2 bouyer Implemented a workaround for reversed _PRT entries. A significant number of 2174 1.1.1.2.2.2 bouyer BIOSs erroneously reverse the _PRT SourceName and the SourceIndex. This 2175 1.1.1.2.2.2 bouyer change dynamically detects and repairs this problem. Provides compatibility 2176 1.1.1.2.2.2 bouyer with MS ACPI. BZ 6859 2177 1.1.1.2.2.2 bouyer 2178 1.1.1.2.2.2 bouyer Simplified the internal ACPI hardware interfaces to eliminate the locking 2179 1.1.1.2.2.2 bouyer flag parameter from Register Read/Write. Added a new external interface, 2180 1.1.1.2.2.2 bouyer AcpiGetRegisterUnlocked. 2181 1.1.1.2.2.2 bouyer 2182 1.1.1.2.2.2 bouyer Fixed a problem where the invocation of a GPE control method could hang. 2183 1.1.1.2.2.2 bouyer This 2184 1.1.1.2.2.2 bouyer was a regression introduced in 20080514. The new method argument count 2185 1.1.1.2.2.2 bouyer validation mechanism can enter an infinite loop when a GPE method is 2186 1.1.1.2.2.2 bouyer dispatched. Problem fixed by removing the obsolete code that passed GPE 2187 1.1.1.2.2.2 bouyer block 2188 1.1.1.2.2.2 bouyer information to the notify handler via the control method parameter pointer. 2189 1.1.1.2.2.2 bouyer 2190 1.1.1.2.2.2 bouyer Fixed a problem where the _SST execution status was incorrectly returned to 2191 1.1.1.2.2.2 bouyer the caller of AcpiEnterSleepStatePrep. This was a regression introduced in 2192 1.1.1.2.2.2 bouyer 20080514. _SST is optional and a NOT_FOUND exception should never be 2193 1.1.1.2.2.2 bouyer returned. BZ 716 2194 1.1.1.2.2.2 bouyer 2195 1.1.1.2.2.2 bouyer Fixed a problem where a deleted object could be accessed from within the AML 2196 1.1.1.2.2.2 bouyer parser. This was a regression introduced in version 20080123 as a fix for 2197 1.1.1.2.2.2 bouyer the 2198 1.1.1.2.2.2 bouyer Unload operator. Lin Ming. BZ 10669 2199 1.1.1.2.2.2 bouyer 2200 1.1.1.2.2.2 bouyer Cleaned up the debug operand dump mechanism. Eliminated unnecessary operands 2201 1.1.1.2.2.2 bouyer and eliminated the use of a negative index in a loop. Operands are now 2202 1.1.1.2.2.2 bouyer displayed in the correct order, not backwards. This also fixes a regression 2203 1.1.1.2.2.2 bouyer introduced in 20080514 on 64-bit systems where the elimination of 2204 1.1.1.2.2.2 bouyer ACPI_NATIVE_UINT caused the negative index to go large and positive. BZ 715 2205 1.1.1.2.2.2 bouyer 2206 1.1.1.2.2.2 bouyer Fixed a possible memory leak in EvPciConfigRegionSetup where the error exit 2207 1.1.1.2.2.2 bouyer path did not delete a locally allocated structure. 2208 1.1.1.2.2.2 bouyer 2209 1.1.1.2.2.2 bouyer Updated definitions for the DMAR and SRAT tables to synchronize with the 2210 1.1.1.2.2.2 bouyer current specifications. Includes disassembler support. 2211 1.1.1.2.2.2 bouyer 2212 1.1.1.2.2.2 bouyer Fixed a problem in the mutex debug code (in utmutex.c) where an incorrect 2213 1.1.1.2.2.2 bouyer loop termination value was used. Loop terminated on iteration early, missing 2214 1.1.1.2.2.2 bouyer one mutex.

Now 2232 1.1.1.2.2.2 bouyer disassemble integer _CID objects back to EisaId invocations, including 2233 1.1.1.2.2.2 bouyer multiple integers within _CID packages. Includes single-step support for 2234 1.1.1.2.2.2 bouyer debugger also. 2235 1.1.1.2.2.2 bouyer 2236 1.1.1.2.2.2 bouyer Disassembler: Added support for DMAR and SRAT table definition changes. 2237 1.1.1.2.2.2 bouyer 2238 1.1.1.2.2.2 bouyer ---------------------------------------- 2239 1.1.1.2.2.2 bouyer 14 May 2008. Summary of changes for version 20080514: 2240 1.1.1.2.2.2 bouyer 2241 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2242 1.1.1.2.2.2 bouyer 2243 1.1.1.2.2.2 bouyer Fixed a problem where GPEs were enabled too early during the ACPICA 2244 1.1.1.2.2.2 bouyer initialization. This could lead to "handler not installed" errors on some 2245 1.1.1.2.2.2 bouyer machines. Moved GPE enable until after _REG/_STA/_INI methods are run. This 2246 1.1.1.2.2.2 bouyer ensures that all operation regions and devices throughout the namespace have 2247 1.1.1.2.2.2 bouyer been initialized before GPEs are enabled. Alexey Starikovskiy, BZ 9916. 2248 1.1.1.2.2.2 bouyer 2249 1.1.1.2.2.2 bouyer Implemented a change to the enter sleep code. Moved execution of the _GTS 2250 1.1.1.2.2.2 bouyer method to just before setting sleep enable bit. The execution was moved from 2251 1.1.1.2.2.2 bouyer AcpiEnterSleepStatePrep to AcpiEnterSleepState. _GTS is now executed 2252 1.1.1.2.2.2 bouyer immediately before the SLP_EN bit is set, as per the ACPI specification. 2253 1.1.1.2.2.2 bouyer Luming Yu, BZ 1653. 2254 1.1.1.2.2.2 bouyer 2255 1.1.1.2.2.2 bouyer Implemented a fix to disable unknown GPEs (2nd version). Now always disable 2256 1.1.1.2.2.2 bouyer the GPE, even if ACPICA thinks that that it is already disabled. It is 2257 1.1.1.2.2.2 bouyer possible that the AML or some other code has enabled the GPE unbeknownst to 2258 1.1.1.2.2.2 bouyer the ACPICA code. 2259 1.1.1.2.2.2 bouyer 2260 1.1.1.2.2.2 bouyer Fixed a problem with the Field operator where zero-length fields would 2261 1.1.1.2.2.2 bouyer return 2262 1.1.1.2.2.2 bouyer an AE_AML_NO_OPERAND exception during table load. Fix enables zero-length 2263 1.1.1.2.2.2 bouyer ASL 2264 1.1.1.2.2.2 bouyer field declarations in Field(), BankField(), and IndexField(). BZ 10606. 2265 1.1.1.2.2.2 bouyer 2266 1.1.1.2.2.2 bouyer Implemented a fix for the Load operator, now load the table at the namespace 2267 1.1.1.2.2.2 bouyer root. This reverts a change introduced in version 20071019. The table is now 2268 1.1.1.2.2.2 bouyer loaded at the namespace root even though this goes against the ACPI 2269 1.1.1.2.2.2 bouyer specification. This provides compatibility with other ACPI implementations. 2270 1.1.1.2.2.2 bouyer The ACPI specification will be updated to reflect this in ACPI 4.0. Lin 2271 1.1.1.2.2.2 bouyer Ming. 2272 1.1.1.2.2.2 bouyer 2273 1.1.1.2.2.2 bouyer Fixed a problem where ACPICA would not Load() tables with unusual 2274 1.1.1.2.2.2 bouyer signatures. 2275 1.1.1.2.2.2 bouyer Now ignore ACPI table signature for Load() operator. Only "SSDT" is 2276 1.1.1.2.2.2 bouyer acceptable to the ACPI spec, but tables are seen with OEMx and null sigs. 2277 1.1.1.2.2.2 bouyer Therefore, signature validation is worthless. Apparently MS ACPI accepts 2278 1.1.1.2.2.2 bouyer such 2279 1.1.1.2.2.2 bouyer signatures, ACPICA must be compatible. BZ 10454. 2280 1.1.1.2.2.2 bouyer 2281 1.1.1.2.2.2 bouyer Fixed a possible negative array index in AcpiUtValidateException. Added NULL 2282 1.1.1.2.2.2 bouyer fields to the exception string arrays to eliminate a -1 subtraction on the 2283 1.1.1.2.2.2 bouyer SubStatus field. 2284 1.1.1.2.2.2 bouyer 2285 1.1.1.2.2.2 bouyer Updated the debug tracking macros to reduce overall code and data size. 2286 1.1.1.2.2.2 bouyer Changed ACPI_MODULE_NAME and ACPI_FUNCTION_NAME to use arrays of strings 2287 1.1.1.2.2.2 bouyer instead of pointers to static strings. Jan Beulich and Bob Moore. 2288 1.1.1.2.2.2 bouyer 2289 1.1.1.2.2.2 bouyer Implemented argument count checking in control method invocation via 2290 1.1.1.2.2.2 bouyer AcpiEvaluateObject. Now emit an error if too few arguments, warning if too 2291 1.1.1.2.2.2 bouyer many. This applies only to extern programmatic control method execution, not 2292 1.1.1.2.2.2 bouyer method-to-method calls within the AML. Lin Ming. 2293 1.1.1.2.2.2 bouyer 2294 1.1.1.2.2.2 bouyer Eliminated the ACPI_NATIVE_UINT type across all ACPICA code. This type is no 2295 1.1.1.2.2.2 bouyer longer needed, especially with the removal of 16-bit support. It was 2296 1.1.1.2.2.2 bouyer replaced 2297 1.1.1.2.2.2 bouyer mostly with UINT32, but also ACPI_SIZE where a type that changes 32/64 bit 2298 1.1.1.2.2.2 bouyer on 2299 1.1.1.2.2.2 bouyer 32/64-bit platforms is required. 2300 1.1.1.2.2.2 bouyer 2301 1.1.1.2.2.2 bouyer Added the C const qualifier for appropriate string constants -- mostly 2302 1.1.1.2.2.2 bouyer MODULE_NAME and printf format strings. Jan Beulich. 2303 1.1.1.2.2.2 bouyer 2304 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2305 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2306 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 2307 1.1.1.2.2.2 bouyer a 2308 1.1.1.2.2.2 bouyer much larger code and data size. 2309 1.1.1.2.2.2 bouyer 2310 1.1.1.2.2.2 bouyer Previous Release: 2311 1.1.1.2.2.2 bouyer Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 2312 1.1.1.2.2.2 bouyer Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 2313 1.1.1.2.2.2 bouyer Current Release: 2314 1.1.1.2.2.2 bouyer Non-Debug Version: 79.5K Code, 16.2K Data, 95.7K Total 2315 1.1.1.2.2.2 bouyer Debug Version: 153.3K Code, 48.3K Data, 201.6K Total 2316 1.1.1.2.2.2 bouyer 2317 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 2318 1.1.1.2.2.2 bouyer 2319 1.1.1.2.2.2 bouyer Implemented ACPI table revision ID validation in the disassembler. Zero is 2320 1.1.1.2.2.2 bouyer always invalid. For DSDTs, the ID controls the interpreter integer width. 1 2321 1.1.1.2.2.2 bouyer means 32-bit and this is unusual. 2 or greater is 64-bit. 2322 1.1.1.2.2.2 bouyer 2323 1.1.1.2.2.2 bouyer ---------------------------------------- 2324 1.1.1.2.2.2 bouyer 21 March 2008. Summary of changes for version 20080321: 2325 1.1.1.2.2.2 bouyer 2326 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2327 1.1.1.2.2.2 bouyer 2328 1.1.1.2.2.2 bouyer Implemented an additional change to the GPE support in order to suppress 2329 1.1.1.2.2.2 bouyer spurious or stray GPEs. The AcpiEvDisableGpe function will now permanently 2330 1.1.1.2.2.2 bouyer disable incoming GPEs that are neither enabled nor disabled -- meaning that 2331 1.1.1.2.2.2 bouyer the GPE is unknown to the system. This should prevent future interrupt 2332 1.1.1.2.2.2 bouyer floods 2333 1.1.1.2.2.2 bouyer from that GPE. BZ 6217 (Zhang Rui) 2334 1.1.1.2.2.2 bouyer 2335 1.1.1.2.2.2 bouyer Fixed a problem where NULL package elements were not returned to the 2336 1.1.1.2.2.2 bouyer AcpiEvaluateObject interface correctly. The element was simply ignored 2337 1.1.1.2.2.2 bouyer instead of returning a NULL ACPI_OBJECT package element, potentially causing 2338 1.1.1.2.2.2 bouyer a buffer overflow and/or confusing the caller who expected a fixed number of 2339 1.1.1.2.2.2 bouyer elements. BZ 10132 (Lin Ming, Bob Moore) 2340 1.1.1.2.2.2 bouyer 2341 1.1.1.2.2.2 bouyer Fixed a problem with the CreateField, CreateXXXField (Bit, Byte, Word, 2342 1.1.1.2.2.2 bouyer Dword, 2343 1.1.1.2.2.2 bouyer Qword), Field, BankField, and IndexField operators when invoked from inside 2344 1.1.1.2.2.2 bouyer an executing control method. In this case, these operators created namespace 2345 1.1.1.2.2.2 bouyer nodes that were incorrectly left marked as permanent nodes instead of 2346 1.1.1.2.2.2 bouyer temporary nodes. This could cause a problem if there is race condition 2347 1.1.1.2.2.2 bouyer between an exiting control method and a running namespace walk. (Reported by 2348 1.1.1.2.2.2 bouyer Linn Crosetto) 2349 1.1.1.2.2.2 bouyer 2350 1.1.1.2.2.2 bouyer Fixed a problem where the CreateField and CreateXXXField operators would 2351 1.1.1.2.2.2 bouyer incorrectly allow duplicate names (the name of the field) with no exception 2352 1.1.1.2.2.2 bouyer generated. 2353 1.1.1.2.2.2 bouyer 2354 1.1.1.2.2.2 bouyer Implemented several changes for Notify handling. Added support for new 2355 1.1.1.2.2.2 bouyer Notify 2356 1.1.1.2.2.2 bouyer values (ACPI 2.0+) and improved the Notify debug output. Notify on 2357 1.1.1.2.2.2 bouyer PowerResource objects is no longer allowed, as per the ACPI specification. 2358 1.1.1.2.2.2 bouyer (Bob Moore, Zhang Rui) 2359 1.1.1.2.2.2 bouyer 2360 1.1.1.2.2.2 bouyer All Reference Objects returned via the AcpiEvaluateObject interface are now 2361 1.1.1.2.2.2 bouyer marked as type "REFERENCE" instead of "ANY". The type ANY is now reserved 2362 1.1.1.2.2.2 bouyer for 2363 1.1.1.2.2.2 bouyer NULL objects - either NULL package elements or unresolved named references. 2364 1.1.1.2.2.2 bouyer 2365 1.1.1.2.2.2 bouyer Fixed a problem where an extraneous debug message was produced for package 2366 1.1.1.2.2.2 bouyer objects (when debugging enabled). The message "Package List length larger 2367 1.1.1.2.2.2 bouyer than NumElements count" is now produced in the correct case, and is now an 2368 1.1.1.2.2.2 bouyer error message rather than a debug message. Added a debug message for the 2369 1.1.1.2.2.2 bouyer opposite case, where NumElements is larger than the Package List (the 2370 1.1.1.2.2.2 bouyer package 2371 1.1.1.2.2.2 bouyer will be padded out with NULL elements as per the ACPI spec.) 2372 1.1.1.2.2.2 bouyer 2373 1.1.1.2.2.2 bouyer Implemented several improvements for the output of the ASL "Debug" object to 2374 1.1.1.2.2.2 bouyer clarify and keep all data for a given object on one output line. 2375 1.1.1.2.2.2 bouyer 2376 1.1.1.2.2.2 bouyer Fixed two size calculation issues with the variable-length Start Dependent 2377 1.1.1.2.2.2 bouyer resource descriptor. 2378 1.1.1.2.2.2 bouyer 2379 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2380 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2381 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 2382 1.1.1.2.2.2 bouyer a much larger code and data size. 2383 1.1.1.2.2.2 bouyer 2384 1.1.1.2.2.2 bouyer Previous Release: 2385 1.1.1.2.2.2 bouyer Non-Debug Version: 79.7K Code, 17.3K Data, 97.0K Total 2386 1.1.1.2.2.2 bouyer Debug Version: 158.9K Code, 64.0K Data, 222.9K Total 2387 1.1.1.2.2.2 bouyer Current Release: 2388 1.1.1.2.2.2 bouyer Non-Debug Version: 80.0K Code, 17.4K Data, 97.4K Total 2389 1.1.1.2.2.2 bouyer Debug Version: 159.4K Code, 64.4K Data, 223.8K Total 2390 1.1.1.2.2.2 bouyer 2391 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 2392 1.1.1.2.2.2 bouyer 2393 1.1.1.2.2.2 bouyer Fixed a problem with the use of the Switch operator where execution of the 2394 1.1.1.2.2.2 bouyer containing method by multiple concurrent threads could cause an 2395 1.1.1.2.2.2 bouyer AE_ALREADY_EXISTS exception. This is caused by the fact that there is no 2396 1.1.1.2.2.2 bouyer actual Switch opcode, it must be simulated with local named temporary 2397 1.1.1.2.2.2 bouyer variables and if/else pairs. The solution chosen was to mark any method that 2398 1.1.1.2.2.2 bouyer uses Switch as Serialized, thus preventing multiple thread entries.

Summary of changes for version 20080213: 2402 1.1.1.2.2.2 bouyer 2403 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2404 1.1.1.2.2.2 bouyer 2405 1.1.1.2.2.2 bouyer Implemented another MS compatibility design change for GPE/Notify handling. 2406 1.1.1.2.2.2 bouyer GPEs are now cleared/enabled asynchronously to allow all pending notifies to 2407 1.1.1.2.2.2 bouyer complete first. It is expected that the OSL will queue the enable request 2408 1.1.1.2.2.2 bouyer behind all pending notify requests (may require changes to the local host 2409 1.1.1.2.2.2 bouyer OSL 2410 1.1.1.2.2.2 bouyer in AcpiOsExecute). Alexey Starikovskiy. 2411 1.1.1.2.2.2 bouyer 2412 1.1.1.2.2.2 bouyer Fixed a problem where buffer and package objects passed as arguments to a 2413 1.1.1.2.2.2 bouyer control method via the external AcpiEvaluateObject interface could cause an 2414 1.1.1.2.2.2 bouyer AE_AML_INTERNAL exception depending on the order and type of operators 2415 1.1.1.2.2.2 bouyer executed by the target control method. 2416 1.1.1.2.2.2 bouyer 2417 1.1.1.2.2.2 bouyer Fixed a problem where resource descriptor size optimization could cause a 2418 1.1.1.2.2.2 bouyer problem when a _CRS resource template is passed to a _SRS method. The _SRS 2419 1.1.1.2.2.2 bouyer resource template must use the same descriptors (with the same size) as 2420 1.1.1.2.2.2 bouyer returned from _CRS. This change affects the following resource descriptors: 2421 1.1.1.2.2.2 bouyer IRQ / IRQNoFlags and StartDependendentFn / StartDependentFnNoPri. (BZ 9487) 2422 1.1.1.2.2.2 bouyer 2423 1.1.1.2.2.2 bouyer Fixed a problem where a CopyObject to RegionField, BankField, and IndexField 2424 1.1.1.2.2.2 bouyer objects did not perform an implicit conversion as it should. These types 2425 1.1.1.2.2.2 bouyer must 2426 1.1.1.2.2.2 bouyer retain their initial type permanently as per the ACPI specification. 2427 1.1.1.2.2.2 bouyer However, 2428 1.1.1.2.2.2 bouyer a CopyObject to all other object types should not perform an implicit 2429 1.1.1.2.2.2 bouyer conversion, as per the ACPI specification. (Lin Ming, Bob Moore) BZ 388 2430 1.1.1.2.2.2 bouyer 2431 1.1.1.2.2.2 bouyer Fixed a problem with the AcpiGetDevices interface where the mechanism to 2432 1.1.1.2.2.2 bouyer match device CIDs did not examine the entire list of available CIDs, but 2433 1.1.1.2.2.2 bouyer instead aborted on the first non-matching CID. Andrew Patterson. 2434 1.1.1.2.2.2 bouyer 2435 1.1.1.2.2.2 bouyer Fixed a regression introduced in version 20071114. The ACPI_HIDWORD macro 2436 1.1.1.2.2.2 bouyer was 2437 1.1.1.2.2.2 bouyer inadvertently changed to return a 16-bit value instead of a 32-bit value, 2438 1.1.1.2.2.2 bouyer truncating the upper dword of a 64-bit value. This macro is only used to 2439 1.1.1.2.2.2 bouyer display debug output, so no incorrect calculations were made. Also, 2440 1.1.1.2.2.2 bouyer reimplemented the macro so that a 64-bit shift is not performed by 2441 1.1.1.2.2.2 bouyer inefficient compilers. 2442 1.1.1.2.2.2 bouyer 2443 1.1.1.2.2.2 bouyer Added missing va_end statements that should correspond with each va_start 2444 1.1.1.2.2.2 bouyer statement. 2445 1.1.1.2.2.2 bouyer 2446 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2447 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Implemented partial disassembler support for the 2462 1.1.1.2.2.2 bouyer complicated HEST table. These tables support the Windows Hardware Error 2463 1.1.1.2.2.2 bouyer Architecture (WHEA). 2464 1.1.1.2.2.2 bouyer 2465 1.1.1.2.2.2 bouyer ---------------------------------------- 2466 1.1.1.2.2.2 bouyer 23 January 2008. Summary of changes for version 20080123: 2467 1.1.1.2.2.2 bouyer 2468 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2469 1.1.1.2.2.2 bouyer 2470 1.1.1.2.2.2 bouyer Added the 2008 copyright to all module headers and signons. This affects 2471 1.1.1.2.2.2 bouyer virtually every file in the ACPICA core subsystem, the iASL compiler, and 2472 1.1.1.2.2.2 bouyer the tools/utilities. 2473 1.1.1.2.2.2 bouyer 2474 1.1.1.2.2.2 bouyer Fixed a problem with the SizeOf operator when used with Package and Buffer 2475 1.1.1.2.2.2 bouyer objects. These objects have deferred execution for some arguments, and the 2476 1.1.1.2.2.2 bouyer execution is now completed before the SizeOf is executed. This problem 2477 1.1.1.2.2.2 bouyer caused 2478 1.1.1.2.2.2 bouyer unexpected AE_PACKAGE_LIMIT errors on some systems (Lin Ming, Bob Moore) BZ 2479 1.1.1.2.2.2 bouyer 9558 2480 1.1.1.2.2.2 bouyer 2481 1.1.1.2.2.2 bouyer Implemented an enhancement to the interpreter "slack mode". In the absence 2482 1.1.1.2.2.2 bouyer of 2483 1.1.1.2.2.2 bouyer an explicit return or an implicitly returned object from the last executed 2484 1.1.1.2.2.2 bouyer opcode, a control method will now implicitly return an integer of value 0 2485 1.1.1.2.2.2 bouyer for 2486 1.1.1.2.2.2 bouyer Microsoft compatibility.

Lin Ming BZ 387, 393 2560 1.1.1.2.2.2 bouyer 2561 1.1.1.2.2.2 bouyer Fixed a problem with AcpiGetDevices where the search of a branch of the 2562 1.1.1.2.2.2 bouyer device tree could be terminated prematurely. In accordance with the ACPI 2563 1.1.1.2.2.2 bouyer specification, the search down the current branch is terminated if a device 2564 1.1.1.2.2.2 bouyer is both not present and not functional (instead of just not present.) Yakui 2565 1.1.1.2.2.2 bouyer Zhao. 2566 1.1.1.2.2.2 bouyer 2567 1.1.1.2.2.2 bouyer Fixed a problem where "unknown" GPEs could be allowed to fire repeatedly if 2568 1.1.1.2.2.2 bouyer the underlying AML code changed the GPE enable registers. Now, any unknown 2569 1.1.1.2.2.2 bouyer incoming GPE (no _Lxx/_Exx method and not the EC GPE) is immediately 2570 1.1.1.2.2.2 bouyer disabled 2571 1.1.1.2.2.2 bouyer instead of simply ignored. Rui Zhang. 2572 1.1.1.2.2.2 bouyer 2573 1.1.1.2.2.2 bouyer Fixed a problem with Index Fields where the Index register was incorrectly 2574 1.1.1.2.2.2 bouyer limited to a maximum of 32 bits. Now any size may be used. 2575 1.1.1.2.2.2 bouyer 2576 1.1.1.2.2.2 bouyer Fixed a couple memory leaks associated with "implicit return" objects when 2577 1.1.1.2.2.2 bouyer the AML Interpreter slack mode is enabled.

Named 2598 1.1.1.2.2.2 bouyer AcpiFixedEventCount[], AcpiSciCount, and AcpiMethodCount respectively. These 2599 1.1.1.2.2.2 bouyer should be useful for debugging and statistics. 2600 1.1.1.2.2.2 bouyer 2601 1.1.1.2.2.2 bouyer Implemented a new external interface, AcpiGetStatistics, to retrieve the 2602 1.1.1.2.2.2 bouyer contents of the various event counters. Returns the current values for 2603 1.1.1.2.2.2 bouyer AcpiSciCount, AcpiGpeCount, the AcpiFixedEventCount array, and 2604 1.1.1.2.2.2 bouyer AcpiMethodCount. The interface can be expanded in the future if new counters 2605 1.1.1.2.2.2 bouyer are added. Device drivers should use this interface rather than access the 2606 1.1.1.2.2.2 bouyer counters directly. 2607 1.1.1.2.2.2 bouyer 2608 1.1.1.2.2.2 bouyer Fixed a problem with the FromBCD and ToBCD operators. With some compilers, 2609 1.1.1.2.2.2 bouyer the ShortDivide function worked incorrectly, causing problems with the BCD 2610 1.1.1.2.2.2 bouyer functions with large input values. A truncation from 64-bit to 32-bit 2611 1.1.1.2.2.2 bouyer inadvertently occurred. Internal BZ 435. Lin Ming 2612 1.1.1.2.2.2 bouyer 2613 1.1.1.2.2.2 bouyer Fixed a problem with Index references passed as method arguments. References 2614 1.1.1.2.2.2 bouyer passed as arguments to control methods were dereferenced immediately (before 2615 1.1.1.2.2.2 bouyer control was passed to the called method). The references are now correctly 2616 1.1.1.2.2.2 bouyer passed directly to the called method. BZ 5389. Lin Ming 2617 1.1.1.2.2.2 bouyer 2618 1.1.1.2.2.2 bouyer Fixed a problem with CopyObject used in conjunction with the Index operator. 2619 1.1.1.2.2.2 bouyer The reference was incorrectly dereferenced before the copy.

Summary of changes for version 20071019: 2652 1.1.1.2.2.2 bouyer 2653 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2654 1.1.1.2.2.2 bouyer 2655 1.1.1.2.2.2 bouyer Fixed a problem with the Alias operator when the target of the alias is a 2656 1.1.1.2.2.2 bouyer named ASL operator that opens a new scope -- Scope, Device, PowerResource, 2657 1.1.1.2.2.2 bouyer Processor, and ThermalZone. In these cases, any children of the original 2658 1.1.1.2.2.2 bouyer operator could not be accessed via the alias, potentially causing unexpected 2659 1.1.1.2.2.2 bouyer AE_NOT_FOUND exceptions. (BZ 9067) 2660 1.1.1.2.2.2 bouyer 2661 1.1.1.2.2.2 bouyer Fixed a problem with the Package operator where all named references were 2662 1.1.1.2.2.2 bouyer created as object references and left otherwise unresolved. According to the 2663 1.1.1.2.2.2 bouyer ACPI specification, a Package can only contain Data Objects or references to 2664 1.1.1.2.2.2 bouyer control methods. The implication is that named references to Data Objects 2665 1.1.1.2.2.2 bouyer (Integer, Buffer, String, Package, BufferField, Field) should be resolved 2666 1.1.1.2.2.2 bouyer immediately upon package creation. This is the approach taken with this 2667 1.1.1.2.2.2 bouyer change. References to all other named objects (Methods, Devices, Scopes, 2668 1.1.1.2.2.2 bouyer etc.) are all now properly created as reference objects. (BZ 5328) 2669 1.1.1.2.2.2 bouyer 2670 1.1.1.2.2.2 bouyer Reverted a change to Notify handling that was introduced in version 2671 1.1.1.2.2.2 bouyer 20070508. This version changed the Notify handling from asynchronous to 2672 1.1.1.2.2.2 bouyer fully synchronous (Device driver Notify handling with respect to the Notify 2673 1.1.1.2.2.2 bouyer ASL operator). It was found that this change caused more problems than it 2674 1.1.1.2.2.2 bouyer solved and was removed by most users. 2675 1.1.1.2.2.2 bouyer 2676 1.1.1.2.2.2 bouyer Fixed a problem with the Increment and Decrement operators where the type of 2677 1.1.1.2.2.2 bouyer the target object could be unexpectedly and incorrectly changed. (BZ 353) 2678 1.1.1.2.2.2 bouyer Lin Ming. 2679 1.1.1.2.2.2 bouyer 2680 1.1.1.2.2.2 bouyer Fixed a problem with the Load and LoadTable operators where the table 2681 1.1.1.2.2.2 bouyer location within the namespace was ignored. Instead, the table was always 2682 1.1.1.2.2.2 bouyer loaded into the root or current scope. Lin Ming. 2683 1.1.1.2.2.2 bouyer 2684 1.1.1.2.2.2 bouyer Fixed a problem with the Load operator when loading a table from a buffer 2685 1.1.1.2.2.2 bouyer object. The input buffer was prematurely zeroed and/or deleted. (BZ 577) 2686 1.1.1.2.2.2 bouyer 2687 1.1.1.2.2.2 bouyer Fixed a problem with the Debug object where a store of a DdbHandle reference 2688 1.1.1.2.2.2 bouyer object to the Debug object could cause a fault. 2689 1.1.1.2.2.2 bouyer 2690 1.1.1.2.2.2 bouyer Added a table checksum verification for the Load operator, in the case where 2691 1.1.1.2.2.2 bouyer the load is from a buffer. (BZ 578). 2692 1.1.1.2.2.2 bouyer 2693 1.1.1.2.2.2 bouyer Implemented additional parameter validation for the LoadTable operator. The 2694 1.1.1.2.2.2 bouyer length of the input strings SignatureString, OemIdString, and OemTableId are 2695 1.1.1.2.2.2 bouyer now checked for maximum lengths.

(Introduced with wildcard support in 2714 1.1.1.2.2.2 bouyer version 20070917.) 2715 1.1.1.2.2.2 bouyer 2716 1.1.1.2.2.2 bouyer ---------------------------------------- 2717 1.1.1.2.2.2 bouyer 19 September 2007. Summary of changes for version 20070919: 2718 1.1.1.2.2.2 bouyer 2719 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2720 1.1.1.2.2.2 bouyer 2721 1.1.1.2.2.2 bouyer Designed and implemented new external interfaces to install and remove 2722 1.1.1.2.2.2 bouyer handlers for ACPI table-related events. Current events that are defined are 2723 1.1.1.2.2.2 bouyer LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as 2724 1.1.1.2.2.2 bouyer they are dynamically loaded and unloaded. See AcpiInstallTableHandler and 2725 1.1.1.2.2.2 bouyer AcpiRemoveTableHandler. (Lin Ming and Bob Moore) 2726 1.1.1.2.2.2 bouyer 2727 1.1.1.2.2.2 bouyer Fixed a problem where the use of the AcpiGbl_AllMethodsSerialized flag 2728 1.1.1.2.2.2 bouyer (acpi_serialized option on Linux) could cause some systems to hang during 2729 1.1.1.2.2.2 bouyer initialization. (Bob Moore) BZ 8171 2730 1.1.1.2.2.2 bouyer 2731 1.1.1.2.2.2 bouyer Fixed a problem where objects of certain types (Device, ThermalZone, 2732 1.1.1.2.2.2 bouyer Processor, PowerResource) can be not found if they are declared and 2733 1.1.1.2.2.2 bouyer referenced from within the same control method (Lin Ming) BZ 341 2734 1.1.1.2.2.2 bouyer 2735 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2736 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2737 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 2738 1.1.1.2.2.2 bouyer a much larger code and data size. 2739 1.1.1.2.2.2 bouyer 2740 1.1.1.2.2.2 bouyer Previous Release: 2741 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total 2742 1.1.1.2.2.2 bouyer Debug Version: 156.3K Code, 63.1K Data, 219.4K Total 2743 1.1.1.2.2.2 bouyer Current Release: 2744 1.1.1.2.2.2 bouyer Non-Debug Version: 78.5K Code, 17.1K Data, 95.6K Total 2745 1.1.1.2.2.2 bouyer Debug Version: 156.7K Code, 63.2K Data, 219.9K Total 2746 1.1.1.2.2.2 bouyer 2747 1.1.1.2.2.2 bouyer 2748 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 2749 1.1.1.2.2.2 bouyer 2750 1.1.1.2.2.2 bouyer Implemented support to allow multiple files to be compiled/disassembled in a 2751 1.1.1.2.2.2 bouyer single invocation. This includes command line wildcard support for both the 2752 1.1.1.2.2.2 bouyer Windows and Unix versions of the compiler. This feature simplifies the 2753 1.1.1.2.2.2 bouyer disassembly and compilation of multiple ACPI tables in a single directory. 2754 1.1.1.2.2.2 bouyer 2755 1.1.1.2.2.2 bouyer ---------------------------------------- 2756 1.1.1.2.2.2 bouyer 08 May 2007. Summary of changes for version 20070508: 2757 1.1.1.2.2.2 bouyer 2758 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2759 1.1.1.2.2.2 bouyer 2760 1.1.1.2.2.2 bouyer Implemented a Microsoft compatibility design change for the handling of the 2761 1.1.1.2.2.2 bouyer Notify AML operator. Previously, notify handlers were dispatched and 2762 1.1.1.2.2.2 bouyer executed completely asynchronously in a deferred thread. The new design 2763 1.1.1.2.2.2 bouyer still executes the notify handlers in a different thread, but the original 2764 1.1.1.2.2.2 bouyer thread that executed the Notify() now waits at a synchronization point for 2765 1.1.1.2.2.2 bouyer the notify handler to complete. Some machines depend on a synchronous Notify 2766 1.1.1.2.2.2 bouyer operator in order to operate correctly. 2767 1.1.1.2.2.2 bouyer 2768 1.1.1.2.2.2 bouyer Implemented support to allow Package objects to be passed as method 2769 1.1.1.2.2.2 bouyer arguments to the external AcpiEvaluateObject interface. Previously, this 2770 1.1.1.2.2.2 bouyer would return the AE_NOT_IMPLEMENTED exception. This feature had not been 2771 1.1.1.2.2.2 bouyer implemented since there were no reserved control methods that required it 2772 1.1.1.2.2.2 bouyer until recently. 2773 1.1.1.2.2.2 bouyer 2774 1.1.1.2.2.2 bouyer Fixed a problem with the internal FADT conversion where ACPI 1.0 FADTs that 2775 1.1.1.2.2.2 bouyer contained invalid non-zero values in reserved fields could cause later 2776 1.1.1.2.2.2 bouyer failures because these fields have meaning in later revisions of the FADT. 2777 1.1.1.2.2.2 bouyer For incoming ACPI 1.0 FADTs, these fields are now always zeroed. (The fields 2778 1.1.1.2.2.2 bouyer are: Preferred_PM_Profile, PSTATE_CNT, CST_CNT, and IAPC_BOOT_FLAGS.) 2779 1.1.1.2.2.2 bouyer 2780 1.1.1.2.2.2 bouyer Fixed a problem where the Global Lock handle was not properly updated if a 2781 1.1.1.2.2.2 bouyer thread that acquired the Global Lock via executing AML code then attempted 2782 1.1.1.2.2.2 bouyer to acquire the lock via the AcpiAcquireGlobalLock interface. Reported by Joe 2783 1.1.1.2.2.2 bouyer Liu. 2784 1.1.1.2.2.2 bouyer 2785 1.1.1.2.2.2 bouyer Fixed a problem in AcpiEvDeleteGpeXrupt where the global interrupt list 2786 1.1.1.2.2.2 bouyer could be corrupted if the interrupt being removed was at the head of the 2787 1.1.1.2.2.2 bouyer list. Reported by Linn Crosetto. 2788 1.1.1.2.2.2 bouyer 2789 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2790 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 2791 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 2792 1.1.1.2.2.2 bouyer a much larger code and data size. 2793 1.1.1.2.2.2 bouyer 2794 1.1.1.2.2.2 bouyer Previous Release: 2795 1.1.1.2.2.2 bouyer Non-Debug Version: 78.0K Code, 17.1K Data, 95.1K Total 2796 1.1.1.2.2.2 bouyer Debug Version: 155.9K Code, 63.1K Data, 219.0K Total 2797 1.1.1.2.2.2 bouyer Current Release: 2798 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 17.0K Data, 95.3K Total 2799 1.1.1.2.2.2 bouyer Debug Version: 156.3K Code, 63.1K Data, 219.4K Total 2800 1.1.1.2.2.2 bouyer 2801 1.1.1.2.2.2 bouyer ---------------------------------------- 2802 1.1.1.2.2.2 bouyer 20 March 2007. Summary of changes for version 20070320: 2803 1.1.1.2.2.2 bouyer 2804 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 2805 1.1.1.2.2.2 bouyer 2806 1.1.1.2.2.2 bouyer Implemented a change to the order of interpretation and evaluation of AML 2807 1.1.1.2.2.2 bouyer operand objects within the AML interpreter. The interpreter now evaluates 2808 1.1.1.2.2.2 bouyer operands in the order that they appear in the AML stream (and the 2809 1.1.1.2.2.2 bouyer corresponding ASL code), instead of in the reverse order (after the entire 2810 1.1.1.2.2.2 bouyer operand list has been parsed). The previous behavior caused several subtle 2811 1.1.1.2.2.2 bouyer incompatibilities with the Microsoft AML interpreter as well as being 2812 1.1.1.2.2.2 bouyer somewhat non-intuitive. BZ 7871, local BZ 263. Valery Podrezov. 2813 1.1.1.2.2.2 bouyer 2814 1.1.1.2.2.2 bouyer Implemented a change to the ACPI Global Lock support. All interfaces to the 2815 1.1.1.2.2.2 bouyer global lock now allow the same thread to acquire the lock multiple times. 2816 1.1.1.2.2.2 bouyer This affects the AcpiAcquireGlobalLock external interface to the global lock 2817 1.1.1.2.2.2 bouyer as well as the internal use of the global lock to support AML fields -- a 2818 1.1.1.2.2.2 bouyer control method that is holding the global lock can now simultaneously access 2819 1.1.1.2.2.2 bouyer AML fields that require global lock protection. Previously, in both cases, 2820 1.1.1.2.2.2 bouyer this would have resulted in an AE_ALREADY_ACQUIRED exception. The change to 2821 1.1.1.2.2.2 bouyer AcpiAcquireGlobalLock is of special interest to drivers for the Embedded 2822 1.1.1.2.2.2 bouyer Controller. There is no change to the behavior of the AML Acquire operator, 2823 1.1.1.2.2.2 bouyer as this can already be used to acquire a mutex multiple times by the same 2824 1.1.1.2.2.2 bouyer thread. BZ 8066. With assistance from Alexey Starikovskiy. 2825 1.1.1.2.2.2 bouyer 2826 1.1.1.2.2.2 bouyer Fixed a problem where invalid objects could be referenced in the AML 2827 1.1.1.2.2.2 bouyer Interpreter after error conditions. During operand evaluation, ensure that 2828 1.1.1.2.2.2 bouyer the internal "Return Object" field is cleared on error and only valid 2829 1.1.1.2.2.2 bouyer pointers are stored there. Caused occasional access to deleted objects that 2830 1.1.1.2.2.2 bouyer resulted in "large reference count" warning messages. Valery Podrezov. 2831 1.1.1.2.2.2 bouyer 2832 1.1.1.2.2.2 bouyer Fixed a problem where an AE_STACK_OVERFLOW internal exception could occur on 2833 1.1.1.2.2.2 bouyer deeply nested control method invocations. BZ 7873, local BZ 487. Valery 2834 1.1.1.2.2.2 bouyer Podrezov. 2835 1.1.1.2.2.2 bouyer 2836 1.1.1.2.2.2 bouyer Fixed an internal problem with the handling of result objects on the 2837 1.1.1.2.2.2 bouyer interpreter result stack. BZ 7872. Valery Podrezov. 2838 1.1.1.2.2.2 bouyer 2839 1.1.1.2.2.2 bouyer Removed obsolete code that handled the case where AML_NAME_OP is the target 2840 1.1.1.2.2.2 bouyer of a reference (Reference.Opcode). This code was no longer necessary. BZ 2841 1.1.1.2.2.2 bouyer 7874. Valery Podrezov. 2842 1.1.1.2.2.2 bouyer 2843 1.1.1.2.2.2 bouyer Removed obsolete ACPI_NO_INTEGER64_SUPPORT from two header files. This was a 2844 1.1.1.2.2.2 bouyer remnant from the previously discontinued 16-bit support. 2845 1.1.1.2.2.2 bouyer 2846 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 2847 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Previously a 2-pass parse/execution, control methods are now 2979 1.1.1.2.2.2 bouyer completely parsed and executed in a single pass. This improves overall 2980 1.1.1.2.2.2 bouyer interpreter performance by ~25%, reduces code size, and reduces CPU stack 2981 1.1.1.2.2.2 bouyer use. (Valery Podrezov + interpreter changes in version 20051202 that 2982 1.1.1.2.2.2 bouyer eliminated namespace loading during the pass one parse.) 2983 1.1.1.2.2.2 bouyer 2984 1.1.1.2.2.2 bouyer Implemented _CID support for PCI Root Bridge detection. If the _HID does not 2985 1.1.1.2.2.2 bouyer match the predefined PCI Root Bridge IDs, the _CID list (if present) is now 2986 1.1.1.2.2.2 bouyer obtained and also checked for an ID match. 2987 1.1.1.2.2.2 bouyer 2988 1.1.1.2.2.2 bouyer Implemented additional support for the PCI _ADR execution: upsearch until a 2989 1.1.1.2.2.2 bouyer device scope is found before executing _ADR. This allows PCI_Config 2990 1.1.1.2.2.2 bouyer operation regions to be declared locally within control methods underneath 2991 1.1.1.2.2.2 bouyer PCI device objects. 2992 1.1.1.2.2.2 bouyer 2993 1.1.1.2.2.2 bouyer Fixed a problem with a possible race condition between threads executing 2994 1.1.1.2.2.2 bouyer AcpiWalkNamespace and the AML interpreter. This condition was removed by 2995 1.1.1.2.2.2 bouyer modifying AcpiWalkNamespace to (by default) ignore all temporary namespace 2996 1.1.1.2.2.2 bouyer entries created during any concurrent control method execution. An 2997 1.1.1.2.2.2 bouyer additional namespace race condition is known to exist between 2998 1.1.1.2.2.2 bouyer AcpiWalkNamespace and the Load/Unload ASL operators and is still under 2999 1.1.1.2.2.2 bouyer investigation. 3000 1.1.1.2.2.2 bouyer 3001 1.1.1.2.2.2 bouyer Restructured the AML ParseLoop function, breaking it into several 3002 1.1.1.2.2.2 bouyer subfunctions in order to reduce CPU stack use and improve maintainability. 3003 1.1.1.2.2.2 bouyer (Mikhail Kouzmich) 3004 1.1.1.2.2.2 bouyer 3005 1.1.1.2.2.2 bouyer AcpiGetHandle: Fix for parameter validation to detect invalid combinations 3006 1.1.1.2.2.2 bouyer of prefix handle and pathname.

When this mode is 3080 1.1.1.2.2.2 bouyer specified, instead of creating a serialization semaphore per control method, 3081 1.1.1.2.2.2 bouyer the interpreter lock is simply no longer released before a blocking 3082 1.1.1.2.2.2 bouyer operation during control method execution. This effectively makes the AML 3083 1.1.1.2.2.2 bouyer Interpreter single-threaded. The overhead of a semaphore per-method is 3084 1.1.1.2.2.2 bouyer eliminated. 3085 1.1.1.2.2.2 bouyer 3086 1.1.1.2.2.2 bouyer Fixed a regression where an error was no longer emitted if a control method 3087 1.1.1.2.2.2 bouyer attempts to create 2 objects of the same name. This once again returns 3088 1.1.1.2.2.2 bouyer AE_ALREADY_EXISTS. When this exception occurs, it invokes the mechanism that 3089 1.1.1.2.2.2 bouyer will dynamically serialize the control method to possible prevent future 3090 1.1.1.2.2.2 bouyer errors. (BZ 440) 3091 1.1.1.2.2.2 bouyer 3092 1.1.1.2.2.2 bouyer Integrated a fix for a problem with PCI Express HID detection in the PCI 3093 1.1.1.2.2.2 bouyer Config Space setup procedure.

Summary of changes for version 20060823: 3184 1.1.1.2.2.2 bouyer 3185 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3186 1.1.1.2.2.2 bouyer 3187 1.1.1.2.2.2 bouyer The Table Manager component has been completely redesigned and 3188 1.1.1.2.2.2 bouyer reimplemented. The new design is much simpler, and reduces the overall code 3189 1.1.1.2.2.2 bouyer and data size of the kernel-resident ACPICA by approximately 5%. Also, it is 3190 1.1.1.2.2.2 bouyer now possible to obtain the ACPI tables very early during kernel 3191 1.1.1.2.2.2 bouyer initialization, even before dynamic memory management is initialized. 3192 1.1.1.2.2.2 bouyer (Alexey Starikovskiy, Fiodor Suietov, Bob Moore) 3193 1.1.1.2.2.2 bouyer 3194 1.1.1.2.2.2 bouyer Obsolete ACPICA interfaces: 3195 1.1.1.2.2.2 bouyer 3196 1.1.1.2.2.2 bouyer - AcpiGetFirmwareTable: Use AcpiGetTable instead (works at early kernel init 3197 1.1.1.2.2.2 bouyer time). 3198 1.1.1.2.2.2 bouyer - AcpiLoadTable: Not needed. 3199 1.1.1.2.2.2 bouyer - AcpiUnloadTable: Not needed. 3200 1.1.1.2.2.2 bouyer 3201 1.1.1.2.2.2 bouyer New ACPICA interfaces: 3202 1.1.1.2.2.2 bouyer 3203 1.1.1.2.2.2 bouyer - AcpiInitializeTables: Must be called before the table manager can be used. 3204 1.1.1.2.2.2 bouyer - AcpiReallocateRootTable: Used to transfer the root table to dynamically 3205 1.1.1.2.2.2 bouyer allocated memory after it becomes available. 3206 1.1.1.2.2.2 bouyer - AcpiGetTableByIndex: Allows the host to easily enumerate all ACPI tables 3207 1.1.1.2.2.2 bouyer in the RSDT/XSDT. 3208 1.1.1.2.2.2 bouyer 3209 1.1.1.2.2.2 bouyer Other ACPICA changes: 3210 1.1.1.2.2.2 bouyer 3211 1.1.1.2.2.2 bouyer - AcpiGetTableHeader returns the actual mapped table header, not a copy. Use 3212 1.1.1.2.2.2 bouyer AcpiOsUnmapMemory to free this mapping. 3213 1.1.1.2.2.2 bouyer - AcpiGetTable returns the actual mapped table. The mapping is managed 3214 1.1.1.2.2.2 bouyer internally and must not be deleted by the caller. Use of this interface 3215 1.1.1.2.2.2 bouyer causes no additional dynamic memory allocation. 3216 1.1.1.2.2.2 bouyer - AcpiFindRootPointer: Support for physical addressing has been eliminated, 3217 1.1.1.2.2.2 bouyer it appeared to be unused. 3218 1.1.1.2.2.2 bouyer - The interface to AcpiOsMapMemory has changed to be consistent with the 3219 1.1.1.2.2.2 bouyer other allocation interfaces. 3220 1.1.1.2.2.2 bouyer - The interface to AcpiOsGetRootPointer has changed to eliminate unnecessary 3221 1.1.1.2.2.2 bouyer parameters. 3222 1.1.1.2.2.2 bouyer - ACPI_PHYSICAL_ADDRESS is now 32 bits on 32-bit platforms, 64 bits on 64- 3223 1.1.1.2.2.2 bouyer bit platforms. Was previously 64 bits on all platforms. 3224 1.1.1.2.2.2 bouyer - The interface to the ACPI Global Lock acquire/release macros have changed 3225 1.1.1.2.2.2 bouyer slightly since ACPICA no longer keeps a local copy of the FACS with a 3226 1.1.1.2.2.2 bouyer constructed pointer to the actual global lock. 3227 1.1.1.2.2.2 bouyer 3228 1.1.1.2.2.2 bouyer Porting to the new table manager: 3229 1.1.1.2.2.2 bouyer 3230 1.1.1.2.2.2 bouyer - AcpiInitializeTables: Must be called once, and can be called anytime 3231 1.1.1.2.2.2 bouyer during the OS initialization process. It allows the host to specify an area 3232 1.1.1.2.2.2 bouyer of memory to be used to store the internal version of the RSDT/XSDT (root 3233 1.1.1.2.2.2 bouyer table). This allows the host to access ACPI tables before memory management 3234 1.1.1.2.2.2 bouyer is initialized and running. 3235 1.1.1.2.2.2 bouyer - AcpiReallocateRootTable: Can be called after memory management is running 3236 1.1.1.2.2.2 bouyer to copy the root table to a dynamically allocated array, freeing up the 3237 1.1.1.2.2.2 bouyer scratch memory specified in the call to AcpiInitializeTables. 3238 1.1.1.2.2.2 bouyer - AcpiSubsystemInitialize: This existing interface is independent of the 3239 1.1.1.2.2.2 bouyer Table Manager, and does not have to be called before the Table Manager can 3240 1.1.1.2.2.2 bouyer be used, it only must be called before the rest of ACPICA can be used. 3241 1.1.1.2.2.2 bouyer - ACPI Tables: Some changes have been made to the names and structure of the 3242 1.1.1.2.2.2 bouyer actbl.h and actbl1.h header files and may require changes to existing code. 3243 1.1.1.2.2.2 bouyer For example, bitfields have been completely removed because of their lack of 3244 1.1.1.2.2.2 bouyer portability across C compilers. 3245 1.1.1.2.2.2 bouyer - Update interfaces to the Global Lock acquire/release macros if local 3246 1.1.1.2.2.2 bouyer versions are used. (see acwin.h) 3247 1.1.1.2.2.2 bouyer 3248 1.1.1.2.2.2 bouyer Obsolete files: tbconvrt.c, tbget.c, tbgetall.c, tbrsdt.c 3249 1.1.1.2.2.2 bouyer 3250 1.1.1.2.2.2 bouyer New files: tbfind.c 3251 1.1.1.2.2.2 bouyer 3252 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 3253 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20060721: 3271 1.1.1.2.2.2 bouyer 3272 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3273 1.1.1.2.2.2 bouyer 3274 1.1.1.2.2.2 bouyer The full source code for the ASL test suite used to validate the iASL 3275 1.1.1.2.2.2 bouyer compiler and the ACPICA core subsystem is being released with the ACPICA 3276 1.1.1.2.2.2 bouyer source for the first time. The source is contained in a separate package and 3277 1.1.1.2.2.2 bouyer consists of over 1100 files that exercise all ASL/AML operators. The package 3278 1.1.1.2.2.2 bouyer should appear on the Intel/ACPI web site shortly. (Valery Podrezov, Fiodor 3279 1.1.1.2.2.2 bouyer Suietov) 3280 1.1.1.2.2.2 bouyer 3281 1.1.1.2.2.2 bouyer Completed a new design and implementation for support of the ACPI Global 3282 1.1.1.2.2.2 bouyer Lock. On the OS side, the global lock is now treated as a standard AML 3283 1.1.1.2.2.2 bouyer mutex. Previously, multiple OS threads could "acquire" the global lock 3284 1.1.1.2.2.2 bouyer simultaneously. However, this could cause the BIOS to be starved out of the 3285 1.1.1.2.2.2 bouyer lock - especially in cases such as the Embedded Controller driver where 3286 1.1.1.2.2.2 bouyer there is a tight coupling between the OS and the BIOS. 3287 1.1.1.2.2.2 bouyer 3288 1.1.1.2.2.2 bouyer Implemented an optimization for the ACPI Global Lock interrupt mechanism. 3289 1.1.1.2.2.2 bouyer The Global Lock interrupt handler no longer queues the execution of a 3290 1.1.1.2.2.2 bouyer separate thread to signal the global lock semaphore. Instead, the semaphore 3291 1.1.1.2.2.2 bouyer is signaled directly from the interrupt handler. 3292 1.1.1.2.2.2 bouyer 3293 1.1.1.2.2.2 bouyer Implemented support within the AML interpreter for package objects that 3294 1.1.1.2.2.2 bouyer contain a larger AML length (package list length) than the package element 3295 1.1.1.2.2.2 bouyer count. In this case, the length of the package is truncated to match the 3296 1.1.1.2.2.2 bouyer package element count. Some BIOS code apparently modifies the package length 3297 1.1.1.2.2.2 bouyer on the fly, and this change supports this behavior. Provides compatibility 3298 1.1.1.2.2.2 bouyer with the MS AML interpreter. (With assistance from Fiodor Suietov) 3299 1.1.1.2.2.2 bouyer 3300 1.1.1.2.2.2 bouyer Implemented a temporary fix for the BankValue parameter of a Bank Field to 3301 1.1.1.2.2.2 bouyer support all constant values, now including the Zero and One opcodes. 3302 1.1.1.2.2.2 bouyer Evaluation of this parameter must eventually be converted to a full TermArg 3303 1.1.1.2.2.2 bouyer evaluation. A not-implemented error is now returned (temporarily) for non- 3304 1.1.1.2.2.2 bouyer constant values for this parameter. 3305 1.1.1.2.2.2 bouyer 3306 1.1.1.2.2.2 bouyer Fixed problem reports (Fiodor Suietov) integrated: 3307 1.1.1.2.2.2 bouyer - Fix for premature object deletion after CopyObject on Operation Region (BZ 3308 1.1.1.2.2.2 bouyer 350) 3309 1.1.1.2.2.2 bouyer 3310 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 3311 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

Summary of changes for version 20060623: 3399 1.1.1.2.2.2 bouyer 3400 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3401 1.1.1.2.2.2 bouyer 3402 1.1.1.2.2.2 bouyer Implemented a new ACPI_SPINLOCK type for the OSL lock interfaces. This 3403 1.1.1.2.2.2 bouyer allows the type to be customized to the host OS for improved efficiency 3404 1.1.1.2.2.2 bouyer (since a spinlock is usually a very small object.) 3405 1.1.1.2.2.2 bouyer 3406 1.1.1.2.2.2 bouyer Implemented support for "ignored" bits in the ACPI registers. According to 3407 1.1.1.2.2.2 bouyer the ACPI specification, these bits should be preserved when writing the 3408 1.1.1.2.2.2 bouyer registers via a read/modify/write cycle. There are 3 bits preserved in this 3409 1.1.1.2.2.2 bouyer manner: PM1_CONTROL[0] (SCI_EN), PM1_CONTROL[9], and PM1_STATUS[11]. 3410 1.1.1.2.2.2 bouyer 3411 1.1.1.2.2.2 bouyer Implemented the initial deployment of new OSL mutex interfaces. Since some 3412 1.1.1.2.2.2 bouyer host operating systems have separate mutex and semaphore objects, this 3413 1.1.1.2.2.2 bouyer feature was requested. The base code now uses mutexes (and the new mutex 3414 1.1.1.2.2.2 bouyer interfaces) wherever a binary semaphore was used previously. However, for 3415 1.1.1.2.2.2 bouyer the current release, the mutex interfaces are defined as macros to map them 3416 1.1.1.2.2.2 bouyer to the existing semaphore interfaces. Therefore, no OSL changes are required 3417 1.1.1.2.2.2 bouyer at this time. (See acpiosxf.h) 3418 1.1.1.2.2.2 bouyer 3419 1.1.1.2.2.2 bouyer Fixed several problems with the support for the control method SyncLevel 3420 1.1.1.2.2.2 bouyer parameter. The SyncLevel now works according to the ACPI specification and 3421 1.1.1.2.2.2 bouyer in concert with the Mutex SyncLevel parameter, since the current SyncLevel 3422 1.1.1.2.2.2 bouyer is a property of the executing thread. Mutual exclusion for control methods 3423 1.1.1.2.2.2 bouyer is now implemented with a mutex instead of a semaphore. 3424 1.1.1.2.2.2 bouyer 3425 1.1.1.2.2.2 bouyer Fixed three instances of the use of the C shift operator in the bitfield 3426 1.1.1.2.2.2 bouyer support code (exfldio.c) to avoid the use of a shift value larger than the 3427 1.1.1.2.2.2 bouyer target data width. The behavior of C compilers is undefined in this case and 3428 1.1.1.2.2.2 bouyer can cause unpredictable results, and therefore the case must be detected and 3429 1.1.1.2.2.2 bouyer avoided. (Fiodor Suietov) 3430 1.1.1.2.2.2 bouyer 3431 1.1.1.2.2.2 bouyer Added an info message whenever an SSDT or OEM table is loaded dynamically 3432 1.1.1.2.2.2 bouyer via the Load() or LoadTable() ASL operators. This should improve debugging 3433 1.1.1.2.2.2 bouyer capability since it will show exactly what tables have been loaded (beyond 3434 1.1.1.2.2.2 bouyer the tables present in the RSDT/XSDT.) 3435 1.1.1.2.2.2 bouyer 3436 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 3437 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler.

This 3459 1.1.1.2.2.2 bouyer change should eliminate all problems caused by attempting to acquire a 3460 1.1.1.2.2.2 bouyer semaphore at interrupt level, and it means that all ACPICA external 3461 1.1.1.2.2.2 bouyer interfaces that directly access the ACPI hardware can be safely called from 3462 1.1.1.2.2.2 bouyer interrupt level. OSL code that implements the semaphore interfaces should be 3463 1.1.1.2.2.2 bouyer able to eliminate any workarounds for being called at interrupt level. 3464 1.1.1.2.2.2 bouyer 3465 1.1.1.2.2.2 bouyer Fixed a regression introduced in 20060526 where the ACPI device 3466 1.1.1.2.2.2 bouyer initialization could be prematurely aborted with an AE_NOT_FOUND if a device 3467 1.1.1.2.2.2 bouyer did not have an optional _INI method. 3468 1.1.1.2.2.2 bouyer 3469 1.1.1.2.2.2 bouyer Fixed an IndexField issue where a write to the Data Register should be 3470 1.1.1.2.2.2 bouyer limited in size to the AccessSize (width) of the IndexField itself.

This will simplify the 3610 1.1.1.2.2.2 bouyer disassembly and recompilation of interdependent tables such as SSDTs since 3611 1.1.1.2.2.2 bouyer these statements will no longer have to be added manually. 3612 1.1.1.2.2.2 bouyer 3613 1.1.1.2.2.2 bouyer Disassembler: Implemented experimental support to automatically detect 3614 1.1.1.2.2.2 bouyer invocations of external control methods and generate appropriate External() 3615 1.1.1.2.2.2 bouyer statements. This is problematic because the AML cannot be correctly parsed 3616 1.1.1.2.2.2 bouyer until the number of arguments for each control method is known. Currently, 3617 1.1.1.2.2.2 bouyer standalone method invocations and invocations as the source operand of a 3618 1.1.1.2.2.2 bouyer Store() statement are supported. 3619 1.1.1.2.2.2 bouyer 3620 1.1.1.2.2.2 bouyer Disassembler: Implemented support for the ASL pseudo-operators LNotEqual, 3621 1.1.1.2.2.2 bouyer LLessEqual, and LGreaterEqual. Previously disassembled as LNot(LEqual()), 3622 1.1.1.2.2.2 bouyer LNot(LGreater()), and LNot(LLess()), this makes the disassembled ASL code 3623 1.1.1.2.2.2 bouyer more readable and likely closer to the original ASL source. 3624 1.1.1.2.2.2 bouyer 3625 1.1.1.2.2.2 bouyer ---------------------------------------- 3626 1.1.1.2.2.2 bouyer 21 April 2006. Summary of changes for version 20060421: 3627 1.1.1.2.2.2 bouyer 3628 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3629 1.1.1.2.2.2 bouyer 3630 1.1.1.2.2.2 bouyer Removed a device initialization optimization introduced in 20051216 where 3631 1.1.1.2.2.2 bouyer the _STA method was not run unless an _INI was also present for the same 3632 1.1.1.2.2.2 bouyer device. This optimization could cause problems because it could allow _INI 3633 1.1.1.2.2.2 bouyer methods to be run within a not-present device subtree. (If a not-present 3634 1.1.1.2.2.2 bouyer device had no _INI, _STA would not be run, the not-present status would not 3635 1.1.1.2.2.2 bouyer be discovered, and the children of the device would be incorrectly 3636 1.1.1.2.2.2 bouyer traversed.) 3637 1.1.1.2.2.2 bouyer 3638 1.1.1.2.2.2 bouyer Implemented a new _STA optimization where namespace subtrees that do not 3639 1.1.1.2.2.2 bouyer contain _INI are identified and ignored during device initialization. 3640 1.1.1.2.2.2 bouyer Selectively running _STA can significantly improve boot time on large 3641 1.1.1.2.2.2 bouyer machines (with assistance from Len Brown.) 3642 1.1.1.2.2.2 bouyer 3643 1.1.1.2.2.2 bouyer Implemented support for the device initialization case where the returned 3644 1.1.1.2.2.2 bouyer _STA flags indicate a device not-present but functioning. In this case, _INI 3645 1.1.1.2.2.2 bouyer is not run, but the device children are examined for presence, as per the 3646 1.1.1.2.2.2 bouyer ACPI specification. 3647 1.1.1.2.2.2 bouyer 3648 1.1.1.2.2.2 bouyer Implemented an additional change to the IndexField support in order to 3649 1.1.1.2.2.2 bouyer conform to MS behavior. The value written to the Index Register is not 3650 1.1.1.2.2.2 bouyer simply a byte offset, it is a byte offset in units of the access width of 3651 1.1.1.2.2.2 bouyer the parent Index Field. (Fiodor Suietov) 3652 1.1.1.2.2.2 bouyer 3653 1.1.1.2.2.2 bouyer Defined and deployed a new OSL interface, AcpiOsValidateAddress. This 3654 1.1.1.2.2.2 bouyer interface is called during the creation of all AML operation regions, and 3655 1.1.1.2.2.2 bouyer allows the host OS to exert control over what addresses it will allow the 3656 1.1.1.2.2.2 bouyer AML code to access. Operation Regions whose addresses are disallowed will 3657 1.1.1.2.2.2 bouyer cause a runtime exception when they are actually accessed (will not affect 3658 1.1.1.2.2.2 bouyer or abort table loading.) See oswinxf or osunixxf for an example 3659 1.1.1.2.2.2 bouyer implementation. 3660 1.1.1.2.2.2 bouyer 3661 1.1.1.2.2.2 bouyer Defined and deployed a new OSL interface, AcpiOsValidateInterface. This 3662 1.1.1.2.2.2 bouyer interface allows the host OS to match the various "optional" 3663 1.1.1.2.2.2 bouyer interface/behavior strings for the _OSI predefined control method as 3664 1.1.1.2.2.2 bouyer appropriate (with assistance from Bjorn Helgaas.) See oswinxf or osunixxf 3665 1.1.1.2.2.2 bouyer for an example implementation. 3666 1.1.1.2.2.2 bouyer 3667 1.1.1.2.2.2 bouyer Restructured and corrected various problems in the exception handling code 3668 1.1.1.2.2.2 bouyer paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod 3669 1.1.1.2.2.2 bouyer (with assistance from Takayoshi Kochi.) 3670 1.1.1.2.2.2 bouyer 3671 1.1.1.2.2.2 bouyer Modified the Linux source converter to ignore quoted string literals while 3672 1.1.1.2.2.2 bouyer converting identifiers from mixed to lower case. This will correct problems 3673 1.1.1.2.2.2 bouyer with the disassembler and other areas where such strings must not be 3674 1.1.1.2.2.2 bouyer modified. 3675 1.1.1.2.2.2 bouyer 3676 1.1.1.2.2.2 bouyer The ACPI_FUNCTION_* macros no longer require quotes around the function 3677 1.1.1.2.2.2 bouyer name. This allows the Linux source converter to convert the names, now that 3678 1.1.1.2.2.2 bouyer the converter ignores quoted strings. 3679 1.1.1.2.2.2 bouyer 3680 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 3681 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3682 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 3683 1.1.1.2.2.2 bouyer a much larger code and data size. 3684 1.1.1.2.2.2 bouyer 3685 1.1.1.2.2.2 bouyer Previous Release: 3686 1.1.1.2.2.2 bouyer 3687 1.1.1.2.2.2 bouyer Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 3688 1.1.1.2.2.2 bouyer Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 3689 1.1.1.2.2.2 bouyer Current Release: 3690 1.1.1.2.2.2 bouyer Non-Debug Version: 79.7K Code, 17.7K Data, 97.4K Total 3691 1.1.1.2.2.2 bouyer Debug Version: 160.1K Code, 65.2K Data, 225.3K Total 3692 1.1.1.2.2.2 bouyer 3693 1.1.1.2.2.2 bouyer 3694 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 3695 1.1.1.2.2.2 bouyer 3696 1.1.1.2.2.2 bouyer Implemented 3 new warnings for iASL, and implemented multiple warning levels 3697 1.1.1.2.2.2 bouyer (w2 flag). 3698 1.1.1.2.2.2 bouyer 3699 1.1.1.2.2.2 bouyer 1) Ignored timeouts: If the TimeoutValue parameter to Wait or Acquire is not 3700 1.1.1.2.2.2 bouyer WAIT_FOREVER (0xFFFF) and the code does not examine the return value to 3701 1.1.1.2.2.2 bouyer check for the possible timeout, a warning is issued. 3702 1.1.1.2.2.2 bouyer 3703 1.1.1.2.2.2 bouyer 2) Useless operators: If an ASL operator does not specify an optional target 3704 1.1.1.2.2.2 bouyer operand and it also does not use the function return value from the 3705 1.1.1.2.2.2 bouyer operator, a warning is issued since the operator effectively does nothing. 3706 1.1.1.2.2.2 bouyer 3707 1.1.1.2.2.2 bouyer 3) Unreferenced objects: If a namespace object is created, but never 3708 1.1.1.2.2.2 bouyer referenced, a warning is issued. This is a warning level 2 since there are 3709 1.1.1.2.2.2 bouyer cases where this is ok, such as when a secondary table is loaded that uses 3710 1.1.1.2.2.2 bouyer the unreferenced objects. Even so, care is taken to only flag objects that 3711 1.1.1.2.2.2 bouyer don't look like they will ever be used. For example, the reserved methods 3712 1.1.1.2.2.2 bouyer (starting with an underscore) are usually not referenced because it is 3713 1.1.1.2.2.2 bouyer expected that the OS will invoke them. 3714 1.1.1.2.2.2 bouyer 3715 1.1.1.2.2.2 bouyer ---------------------------------------- 3716 1.1.1.2.2.2 bouyer 31 March 2006. Summary of changes for version 20060331: 3717 1.1.1.2.2.2 bouyer 3718 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3719 1.1.1.2.2.2 bouyer 3720 1.1.1.2.2.2 bouyer Implemented header file support for the following additional ACPI tables: 3721 1.1.1.2.2.2 bouyer ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, 3722 1.1.1.2.2.2 bouyer all current and known ACPI tables are now defined in the ACPICA headers and 3723 1.1.1.2.2.2 bouyer are available for use by device drivers and other software. 3724 1.1.1.2.2.2 bouyer 3725 1.1.1.2.2.2 bouyer Implemented support to allow tables that contain ACPI names with invalid 3726 1.1.1.2.2.2 bouyer characters to be loaded. Previously, this would cause the table load to 3727 1.1.1.2.2.2 bouyer fail, but since there are several known cases of such tables on existing 3728 1.1.1.2.2.2 bouyer machines, this change was made to enable ACPI support for them. Also, this 3729 1.1.1.2.2.2 bouyer matches the behavior of the Microsoft ACPI implementation. 3730 1.1.1.2.2.2 bouyer 3731 1.1.1.2.2.2 bouyer Fixed a couple regressions introduced during the memory optimization in the 3732 1.1.1.2.2.2 bouyer 20060317 release. The namespace node definition required additional 3733 1.1.1.2.2.2 bouyer reorganization and an internal datatype that had been changed to 8-bit was 3734 1.1.1.2.2.2 bouyer restored to 32-bit. (Valery Podrezov) 3735 1.1.1.2.2.2 bouyer 3736 1.1.1.2.2.2 bouyer Fixed a problem where a null pointer passed to AcpiUtDeleteGenericState 3737 1.1.1.2.2.2 bouyer could be passed through to AcpiOsReleaseObject which is unexpected. Such 3738 1.1.1.2.2.2 bouyer null pointers are now trapped and ignored, matching the behavior of the 3739 1.1.1.2.2.2 bouyer previous implementation before the deployment of AcpiOsReleaseObject. 3740 1.1.1.2.2.2 bouyer (Valery Podrezov, Fiodor Suietov) 3741 1.1.1.2.2.2 bouyer 3742 1.1.1.2.2.2 bouyer Fixed a memory mapping leak during the deletion of a SystemMemory operation 3743 1.1.1.2.2.2 bouyer region where a cached memory mapping was not deleted. This became a 3744 1.1.1.2.2.2 bouyer noticeable problem for operation regions that are defined within frequently 3745 1.1.1.2.2.2 bouyer used control methods. (Dana Meyers) 3746 1.1.1.2.2.2 bouyer 3747 1.1.1.2.2.2 bouyer Reorganized the ACPI table header files into two main files: one for the 3748 1.1.1.2.2.2 bouyer ACPI tables consumed by the ACPICA core, and another for the miscellaneous 3749 1.1.1.2.2.2 bouyer ACPI tables that are consumed by the drivers and other software. The various 3750 1.1.1.2.2.2 bouyer FADT definitions were merged into one common section and three different 3751 1.1.1.2.2.2 bouyer tables (ACPI 1.0, 1.0+, and 2.0) 3752 1.1.1.2.2.2 bouyer 3753 1.1.1.2.2.2 bouyer Example Code and Data Size: These are the sizes for the OS-independent 3754 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. The 3755 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace mechanism and has 3756 1.1.1.2.2.2 bouyer a much larger code and data size. 3757 1.1.1.2.2.2 bouyer 3758 1.1.1.2.2.2 bouyer Previous Release: 3759 1.1.1.2.2.2 bouyer Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 3760 1.1.1.2.2.2 bouyer Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 3761 1.1.1.2.2.2 bouyer Current Release: 3762 1.1.1.2.2.2 bouyer Non-Debug Version: 81.1K Code, 17.7K Data, 98.8K Total 3763 1.1.1.2.2.2 bouyer Debug Version: 158.9K Code, 64.9K Data, 223.8K Total 3764 1.1.1.2.2.2 bouyer 3765 1.1.1.2.2.2 bouyer 3766 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 3767 1.1.1.2.2.2 bouyer 3768 1.1.1.2.2.2 bouyer Disassembler: Implemented support to decode and format all non-AML ACPI 3769 1.1.1.2.2.2 bouyer tables (tables other than DSDTs and SSDTs.) This includes the new tables 3770 1.1.1.2.2.2 bouyer added to the ACPICA headers, therefore all current and known ACPI tables are 3771 1.1.1.2.2.2 bouyer supported. 3772 1.1.1.2.2.2 bouyer 3773 1.1.1.2.2.2 bouyer Disassembler: The change to allow ACPI names with invalid characters also 3774 1.1.1.2.2.2 bouyer enables the disassembly of such tables. Invalid characters within names are 3775 1.1.1.2.2.2 bouyer changed to '*' to make the name printable; the iASL compiler will still 3776 1.1.1.2.2.2 bouyer generate an error for such names, however, since this is an invalid ACPI 3777 1.1.1.2.2.2 bouyer character. 3778 1.1.1.2.2.2 bouyer 3779 1.1.1.2.2.2 bouyer Implemented an option for AcpiXtract (-a) to extract all tables found in the 3780 1.1.1.2.2.2 bouyer input file. The default invocation extracts only the DSDTs and SSDTs. 3781 1.1.1.2.2.2 bouyer 3782 1.1.1.2.2.2 bouyer Fixed a couple of gcc generation issues for iASL and AcpiExec and added a 3783 1.1.1.2.2.2 bouyer makefile for the AcpiXtract utility. 3784 1.1.1.2.2.2 bouyer 3785 1.1.1.2.2.2 bouyer ---------------------------------------- 3786 1.1.1.2.2.2 bouyer 17 March 2006. Summary of changes for version 20060317: 3787 1.1.1.2.2.2 bouyer 3788 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3789 1.1.1.2.2.2 bouyer 3790 1.1.1.2.2.2 bouyer Implemented the use of a cache object for all internal namespace nodes. 3791 1.1.1.2.2.2 bouyer Since there are about 1000 static nodes in a typical system, this will 3792 1.1.1.2.2.2 bouyer decrease memory use for cache implementations that minimize per-allocation 3793 1.1.1.2.2.2 bouyer overhead (such as a slab allocator.) 3794 1.1.1.2.2.2 bouyer 3795 1.1.1.2.2.2 bouyer Removed the reference count mechanism for internal namespace nodes, since it 3796 1.1.1.2.2.2 bouyer was deemed unnecessary. This reduces the size of each namespace node by 3797 1.1.1.2.2.2 bouyer about 5%-10% on all platforms. Nodes are now 20 bytes for the 32-bit case, 3798 1.1.1.2.2.2 bouyer and 32 bytes for the 64-bit case. 3799 1.1.1.2.2.2 bouyer 3800 1.1.1.2.2.2 bouyer Optimized several internal data structures to reduce object size on 64-bit 3801 1.1.1.2.2.2 bouyer platforms by packing data within the 64-bit alignment. This includes the 3802 1.1.1.2.2.2 bouyer frequently used ACPI_OPERAND_OBJECT, of which there can be ~1000 static 3803 1.1.1.2.2.2 bouyer instances corresponding to the namespace objects. 3804 1.1.1.2.2.2 bouyer 3805 1.1.1.2.2.2 bouyer Added two new strings for the predefined _OSI method: "Windows 2001.1 SP1" 3806 1.1.1.2.2.2 bouyer and "Windows 2006". 3807 1.1.1.2.2.2 bouyer 3808 1.1.1.2.2.2 bouyer Split the allocation tracking mechanism out to a separate file, from 3809 1.1.1.2.2.2 bouyer utalloc.c to uttrack.c. This mechanism appears to be only useful for 3810 1.1.1.2.2.2 bouyer application-level code. Kernels may wish to not include uttrack.c in 3811 1.1.1.2.2.2 bouyer distributions. 3812 1.1.1.2.2.2 bouyer 3813 1.1.1.2.2.2 bouyer Removed all remnants of the obsolete ACPI_REPORT_* macros and the associated 3814 1.1.1.2.2.2 bouyer code. (These macros have been replaced by the ACPI_ERROR and ACPI_WARNING 3815 1.1.1.2.2.2 bouyer macros.) 3816 1.1.1.2.2.2 bouyer 3817 1.1.1.2.2.2 bouyer Code and Data Size: These are the sizes for the acpica.lib produced by the 3818 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 32-bit compiler. The values do not include any ACPI 3819 1.1.1.2.2.2 bouyer driver or OSPM code. The debug version of the code includes the debug output 3820 1.1.1.2.2.2 bouyer trace mechanism and has a much larger code and data size. Note that these 3821 1.1.1.2.2.2 bouyer values will vary depending on the efficiency of the compiler and the 3822 1.1.1.2.2.2 bouyer compiler options used during generation. 3823 1.1.1.2.2.2 bouyer 3824 1.1.1.2.2.2 bouyer Previous Release: 3825 1.1.1.2.2.2 bouyer Non-Debug Version: 81.1K Code, 17.8K Data, 98.9K Total 3826 1.1.1.2.2.2 bouyer Debug Version: 161.6K Code, 65.7K Data, 227.3K Total 3827 1.1.1.2.2.2 bouyer Current Release: 3828 1.1.1.2.2.2 bouyer Non-Debug Version: 80.9K Code, 17.7K Data, 98.6K Total 3829 1.1.1.2.2.2 bouyer Debug Version: 158.7K Code, 64.8K Data, 223.5K Total 3830 1.1.1.2.2.2 bouyer 3831 1.1.1.2.2.2 bouyer 3832 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler and Tools: 3833 1.1.1.2.2.2 bouyer 3834 1.1.1.2.2.2 bouyer Implemented an ANSI C version of the acpixtract utility. This version will 3835 1.1.1.2.2.2 bouyer automatically extract the DSDT and all SSDTs from the input acpidump text 3836 1.1.1.2.2.2 bouyer file and dump the binary output to separate files. It can also display a 3837 1.1.1.2.2.2 bouyer summary of the input file including the headers for each table found and 3838 1.1.1.2.2.2 bouyer will extract any single ACPI table, with any signature. (See 3839 1.1.1.2.2.2 bouyer source/tools/acpixtract) 3840 1.1.1.2.2.2 bouyer 3841 1.1.1.2.2.2 bouyer ---------------------------------------- 3842 1.1.1.2.2.2 bouyer 10 March 2006. Summary of changes for version 20060310: 3843 1.1.1.2.2.2 bouyer 3844 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 3845 1.1.1.2.2.2 bouyer 3846 1.1.1.2.2.2 bouyer Tagged all external interfaces to the subsystem with the new 3847 1.1.1.2.2.2 bouyer ACPI_EXPORT_SYMBOL macro. This macro can be defined as necessary to assist 3848 1.1.1.2.2.2 bouyer kernel integration. For Linux, the macro resolves to the EXPORT_SYMBOL 3849 1.1.1.2.2.2 bouyer macro.

These macros are simpler and generate less 4019 1.1.1.2.2.2 bouyer code than their predecessors. The new macros ACPI_ERROR, ACPI_EXCEPTION, 4020 1.1.1.2.2.2 bouyer ACPI_WARNING, and ACPI_INFO replace the ACPI_REPORT_* macros. The older 4021 1.1.1.2.2.2 bouyer macros remain defined to allow ACPI drivers time to migrate to the new 4022 1.1.1.2.2.2 bouyer macros. 4023 1.1.1.2.2.2 bouyer 4024 1.1.1.2.2.2 bouyer Implemented the ACPI_CPU_FLAGS type to simplify host OS integration of the 4025 1.1.1.2.2.2 bouyer Acquire/Release Lock OSL interfaces. 4026 1.1.1.2.2.2 bouyer 4027 1.1.1.2.2.2 bouyer Fixed a problem where Alias ASL operators are sometimes not correctly 4028 1.1.1.2.2.2 bouyer resolved, in both the interpreter and the iASL compiler. 4029 1.1.1.2.2.2 bouyer 4030 1.1.1.2.2.2 bouyer Fixed several problems with the implementation of the ConcatenateResTemplate 4031 1.1.1.2.2.2 bouyer ASL operator. As per the ACPI specification, zero length buffers are now 4032 1.1.1.2.2.2 bouyer treated as a single EndTag. One-length buffers always cause a fatal 4033 1.1.1.2.2.2 bouyer exception. Non-zero length buffers that do not end with a full 2-byte EndTag 4034 1.1.1.2.2.2 bouyer cause a fatal exception. 4035 1.1.1.2.2.2 bouyer 4036 1.1.1.2.2.2 bouyer Fixed a possible structure overwrite in the AcpiGetObjectInfo external 4037 1.1.1.2.2.2 bouyer interface.

Over 200 cases were converted to create a total of over 380 4076 1.1.1.2.2.2 bouyer error/warning messages across the ACPICA code. This increases the code and 4077 1.1.1.2.2.2 bouyer data size of the default non-debug version of the code somewhat (about 13K), 4078 1.1.1.2.2.2 bouyer but all error/warning reporting may be disabled if desired (and code 4079 1.1.1.2.2.2 bouyer eliminated) by specifying the ACPI_NO_ERROR_MESSAGES compile-time 4080 1.1.1.2.2.2 bouyer configuration option.

Enabled via the interpreter 4115 1.1.1.2.2.2 bouyer slack flag, this should eliminate AE_NOT_FOUND exceptions seen on machines 4116 1.1.1.2.2.2 bouyer that contain such code. 4117 1.1.1.2.2.2 bouyer 4118 1.1.1.2.2.2 bouyer Implemented an optimization to the initialization sequence that can improve 4119 1.1.1.2.2.2 bouyer boot time. During ACPI device initialization, the _STA method is now run if 4120 1.1.1.2.2.2 bouyer and only if the _INI method exists. The _STA method is used to determine if 4121 1.1.1.2.2.2 bouyer the device is present; An _INI can only be run if _STA returns present, but 4122 1.1.1.2.2.2 bouyer it is a waste of time to run the _STA method if the _INI does not exist. 4123 1.1.1.2.2.2 bouyer (Prototype and assistance from Dong Wei) 4124 1.1.1.2.2.2 bouyer 4125 1.1.1.2.2.2 bouyer Implemented use of the C99 uintptr_t for the pointer casting macros if it is 4126 1.1.1.2.2.2 bouyer available in the current compiler. Otherwise, the default (void *) cast is 4127 1.1.1.2.2.2 bouyer used as before. 4128 1.1.1.2.2.2 bouyer 4129 1.1.1.2.2.2 bouyer Fixed some possible memory leaks found within the execution path of the 4130 1.1.1.2.2.2 bouyer Break, Continue, If, and CreateField operators. (Valery Podrezov) 4131 1.1.1.2.2.2 bouyer 4132 1.1.1.2.2.2 bouyer Fixed a problem introduced in the 20051202 release where an exception is 4133 1.1.1.2.2.2 bouyer generated during method execution if a control method attempts to declare 4134 1.1.1.2.2.2 bouyer another method. 4135 1.1.1.2.2.2 bouyer 4136 1.1.1.2.2.2 bouyer Moved resource descriptor string constants that are used by both the AML 4137 1.1.1.2.2.2 bouyer disassembler and AML debugger to the common utilities directory so that 4138 1.1.1.2.2.2 bouyer these components are independent. 4139 1.1.1.2.2.2 bouyer 4140 1.1.1.2.2.2 bouyer Implemented support in the AcpiExec utility (-e switch) to globally ignore 4141 1.1.1.2.2.2 bouyer exceptions during control method execution (method is not aborted.) 4142 1.1.1.2.2.2 bouyer 4143 1.1.1.2.2.2 bouyer Added the rsinfo.c source file to the AcpiExec makefile for Linux/Unix 4144 1.1.1.2.2.2 bouyer generation. 4145 1.1.1.2.2.2 bouyer 4146 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4147 1.1.1.2.2.2 bouyer subsystem are shown below. These are the code and data sizes for the 4148 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4149 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug version of the 4150 1.1.1.2.2.2 bouyer code includes the debug output trace mechanism and has a much larger code 4151 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the efficiency 4152 1.1.1.2.2.2 bouyer of the compiler and the compiler options used during generation. 4153 1.1.1.2.2.2 bouyer 4154 1.1.1.2.2.2 bouyer Previous Release: 4155 1.1.1.2.2.2 bouyer Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4156 1.1.1.2.2.2 bouyer Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 4157 1.1.1.2.2.2 bouyer Current Release: 4158 1.1.1.2.2.2 bouyer Non-Debug Version: 76.6K Code, 12.3K Data, 88.9K Total 4159 1.1.1.2.2.2 bouyer Debug Version: 163.7K Code, 67.5K Data, 231.2K Total 4160 1.1.1.2.2.2 bouyer 4161 1.1.1.2.2.2 bouyer 4162 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4163 1.1.1.2.2.2 bouyer 4164 1.1.1.2.2.2 bouyer Fixed a problem where a CPU stack overflow fault could occur if a recursive 4165 1.1.1.2.2.2 bouyer method call was made from within a Return statement. 4166 1.1.1.2.2.2 bouyer 4167 1.1.1.2.2.2 bouyer ---------------------------------------- 4168 1.1.1.2.2.2 bouyer 02 December 2005. Summary of changes for version 20051202: 4169 1.1.1.2.2.2 bouyer 4170 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4171 1.1.1.2.2.2 bouyer 4172 1.1.1.2.2.2 bouyer Modified the parsing of control methods to no longer create namespace 4173 1.1.1.2.2.2 bouyer objects during the first pass of the parse. Objects are now created only 4174 1.1.1.2.2.2 bouyer during the execute phase, at the moment the namespace creation operator is 4175 1.1.1.2.2.2 bouyer encountered in the AML (Name, OperationRegion, CreateByteField, etc.) This 4176 1.1.1.2.2.2 bouyer should eliminate ALREADY_EXISTS exceptions seen on some machines where 4177 1.1.1.2.2.2 bouyer reentrant control methods are protected by an AML mutex. The mutex will now 4178 1.1.1.2.2.2 bouyer correctly block multiple threads from attempting to create the same object 4179 1.1.1.2.2.2 bouyer more than once. 4180 1.1.1.2.2.2 bouyer 4181 1.1.1.2.2.2 bouyer Increased the number of available Owner Ids for namespace object tracking 4182 1.1.1.2.2.2 bouyer from 32 to 255. This should eliminate the OWNER_ID_LIMIT exceptions seen on 4183 1.1.1.2.2.2 bouyer some machines with a large number of ACPI tables (either static or dynamic). 4184 1.1.1.2.2.2 bouyer 4185 1.1.1.2.2.2 bouyer Fixed a problem with the AcpiExec utility where a fault could occur when the 4186 1.1.1.2.2.2 bouyer -b switch (batch mode) is used. 4187 1.1.1.2.2.2 bouyer 4188 1.1.1.2.2.2 bouyer Enhanced the namespace dump routine to output the owner ID for each 4189 1.1.1.2.2.2 bouyer namespace object. 4190 1.1.1.2.2.2 bouyer 4191 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4192 1.1.1.2.2.2 bouyer subsystem are shown below. These are the code and data sizes for the 4193 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4194 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug version of the 4195 1.1.1.2.2.2 bouyer code includes the debug output trace mechanism and has a much larger code 4196 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the efficiency 4197 1.1.1.2.2.2 bouyer of the compiler and the compiler options used during generation. 4198 1.1.1.2.2.2 bouyer 4199 1.1.1.2.2.2 bouyer Previous Release: 4200 1.1.1.2.2.2 bouyer Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4201 1.1.1.2.2.2 bouyer Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4202 1.1.1.2.2.2 bouyer Current Release: 4203 1.1.1.2.2.2 bouyer Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4204 1.1.1.2.2.2 bouyer Debug Version: 163.2K Code, 67.4K Data, 230.6K Total 4205 1.1.1.2.2.2 bouyer 4206 1.1.1.2.2.2 bouyer 4207 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4208 1.1.1.2.2.2 bouyer 4209 1.1.1.2.2.2 bouyer Fixed a parse error during compilation of certain Switch/Case constructs. To 4210 1.1.1.2.2.2 bouyer simplify the parse, the grammar now allows for multiple Default statements 4211 1.1.1.2.2.2 bouyer and this error is now detected and flagged during the analysis phase. 4212 1.1.1.2.2.2 bouyer 4213 1.1.1.2.2.2 bouyer Disassembler: The disassembly now includes the contents of the original 4214 1.1.1.2.2.2 bouyer table header within a comment at the start of the file. This includes the 4215 1.1.1.2.2.2 bouyer name and version of the original ASL compiler. 4216 1.1.1.2.2.2 bouyer 4217 1.1.1.2.2.2 bouyer ---------------------------------------- 4218 1.1.1.2.2.2 bouyer 17 November 2005. Summary of changes for version 20051117: 4219 1.1.1.2.2.2 bouyer 4220 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4221 1.1.1.2.2.2 bouyer 4222 1.1.1.2.2.2 bouyer Fixed a problem in the AML parser where the method thread count could be 4223 1.1.1.2.2.2 bouyer decremented below zero if any errors occurred during the method parse phase. 4224 1.1.1.2.2.2 bouyer This should eliminate AE_AML_METHOD_LIMIT exceptions seen on some machines. 4225 1.1.1.2.2.2 bouyer This also fixed a related regression with the mechanism that detects and 4226 1.1.1.2.2.2 bouyer corrects methods that cannot properly handle reentrancy (related to the 4227 1.1.1.2.2.2 bouyer deployment of the new OwnerId mechanism.) 4228 1.1.1.2.2.2 bouyer 4229 1.1.1.2.2.2 bouyer Eliminated the pre-parsing of control methods (to detect errors) during 4230 1.1.1.2.2.2 bouyer table load. Related to the problem above, this was causing unwind issues if 4231 1.1.1.2.2.2 bouyer any errors occurred during the parse, and it seemed to be overkill. A table 4232 1.1.1.2.2.2 bouyer load should not be aborted if there are problems with any single control 4233 1.1.1.2.2.2 bouyer method, thus rendering this feature rather pointless. 4234 1.1.1.2.2.2 bouyer 4235 1.1.1.2.2.2 bouyer Fixed a problem with the new table-driven resource manager where an internal 4236 1.1.1.2.2.2 bouyer buffer overflow could occur for small resource templates. 4237 1.1.1.2.2.2 bouyer 4238 1.1.1.2.2.2 bouyer Implemented a new external interface, AcpiGetVendorResource. This interface 4239 1.1.1.2.2.2 bouyer will find and return a vendor-defined resource descriptor within a _CRS or 4240 1.1.1.2.2.2 bouyer _PRS method via an ACPI 3.0 UUID match. With assistance from Bjorn Helgaas. 4241 1.1.1.2.2.2 bouyer 4242 1.1.1.2.2.2 bouyer Removed the length limit (200) on string objects as per the upcoming ACPI 4243 1.1.1.2.2.2 bouyer 3.0A specification. This affects the following areas of the interpreter: 1) 4244 1.1.1.2.2.2 bouyer any implicit conversion of a Buffer to a String, 2) a String object result 4245 1.1.1.2.2.2 bouyer of the ASL Concatentate operator, 3) the String object result of the ASL 4246 1.1.1.2.2.2 bouyer ToString operator. 4247 1.1.1.2.2.2 bouyer 4248 1.1.1.2.2.2 bouyer Fixed a problem in the Windows OS interface layer (OSL) where a WAIT_FOREVER 4249 1.1.1.2.2.2 bouyer on a semaphore object would incorrectly timeout. This allows the 4250 1.1.1.2.2.2 bouyer multithreading features of the AcpiExec utility to work properly under 4251 1.1.1.2.2.2 bouyer Windows. 4252 1.1.1.2.2.2 bouyer 4253 1.1.1.2.2.2 bouyer Updated the Linux makefiles for the iASL compiler and AcpiExec to include 4254 1.1.1.2.2.2 bouyer the recently added file named "utresrc.c". 4255 1.1.1.2.2.2 bouyer 4256 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4257 1.1.1.2.2.2 bouyer subsystem are shown below. These are the code and data sizes for the 4258 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4259 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug version of the 4260 1.1.1.2.2.2 bouyer code includes the debug output trace mechanism and has a much larger code 4261 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the efficiency 4262 1.1.1.2.2.2 bouyer of the compiler and the compiler options used during generation. 4263 1.1.1.2.2.2 bouyer 4264 1.1.1.2.2.2 bouyer Previous Release: 4265 1.1.1.2.2.2 bouyer Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 4266 1.1.1.2.2.2 bouyer Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4267 1.1.1.2.2.2 bouyer Current Release: 4268 1.1.1.2.2.2 bouyer Non-Debug Version: 76.3K Code, 12.3K Data, 88.6K Total 4269 1.1.1.2.2.2 bouyer Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4270 1.1.1.2.2.2 bouyer 4271 1.1.1.2.2.2 bouyer 4272 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4273 1.1.1.2.2.2 bouyer 4274 1.1.1.2.2.2 bouyer Removed the limit (200) on string objects as per the upcoming ACPI 3.0A 4275 1.1.1.2.2.2 bouyer specification. For the iASL compiler, this means that string literals within 4276 1.1.1.2.2.2 bouyer the source ASL can be of any length. 4277 1.1.1.2.2.2 bouyer 4278 1.1.1.2.2.2 bouyer Enhanced the listing output to dump the AML code for resource descriptors 4279 1.1.1.2.2.2 bouyer immediately after the ASL code for each descriptor, instead of in a block at 4280 1.1.1.2.2.2 bouyer the end of the entire resource template. 4281 1.1.1.2.2.2 bouyer 4282 1.1.1.2.2.2 bouyer Enhanced the compiler debug output to dump the entire original parse tree 4283 1.1.1.2.2.2 bouyer constructed during the parse phase, before any transforms are applied to the 4284 1.1.1.2.2.2 bouyer tree. The transformed tree is dumped also. 4285 1.1.1.2.2.2 bouyer 4286 1.1.1.2.2.2 bouyer ---------------------------------------- 4287 1.1.1.2.2.2 bouyer 02 November 2005. Summary of changes for version 20051102: 4288 1.1.1.2.2.2 bouyer 4289 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4290 1.1.1.2.2.2 bouyer 4291 1.1.1.2.2.2 bouyer Modified the subsystem initialization sequence to improve GPE support. The 4292 1.1.1.2.2.2 bouyer GPE initialization has been split into two parts in order to defer execution 4293 1.1.1.2.2.2 bouyer of the _PRW methods (Power Resources for Wake) until after the hardware is 4294 1.1.1.2.2.2 bouyer fully initialized and the SCI handler is installed. This allows the _PRW 4295 1.1.1.2.2.2 bouyer methods to access fields protected by the Global Lock. This will fix systems 4296 1.1.1.2.2.2 bouyer where a NO_GLOBAL_LOCK exception has been seen during initialization. 4297 1.1.1.2.2.2 bouyer 4298 1.1.1.2.2.2 bouyer Converted the ACPI internal object disassemble and display code within the 4299 1.1.1.2.2.2 bouyer AML debugger to fully table-driven operation, reducing code size and 4300 1.1.1.2.2.2 bouyer increasing maintainability. 4301 1.1.1.2.2.2 bouyer 4302 1.1.1.2.2.2 bouyer Fixed a regression with the ConcatenateResTemplate() ASL operator introduced 4303 1.1.1.2.2.2 bouyer in the 20051021 release. 4304 1.1.1.2.2.2 bouyer 4305 1.1.1.2.2.2 bouyer Implemented support for "local" internal ACPI object types within the 4306 1.1.1.2.2.2 bouyer debugger "Object" command and the AcpiWalkNamespace external interfaces. 4307 1.1.1.2.2.2 bouyer These local types include RegionFields, BankFields, IndexFields, Alias, and 4308 1.1.1.2.2.2 bouyer reference objects. 4309 1.1.1.2.2.2 bouyer 4310 1.1.1.2.2.2 bouyer Moved common AML resource handling code into a new file, "utresrc.c". This 4311 1.1.1.2.2.2 bouyer code is shared by both the Resource Manager and the AML Debugger. 4312 1.1.1.2.2.2 bouyer 4313 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4314 1.1.1.2.2.2 bouyer subsystem are shown below. These are the code and data sizes for the 4315 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4316 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug version of the 4317 1.1.1.2.2.2 bouyer code includes the debug output trace mechanism and has a much larger code 4318 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the efficiency 4319 1.1.1.2.2.2 bouyer of the compiler and the compiler options used during generation. 4320 1.1.1.2.2.2 bouyer 4321 1.1.1.2.2.2 bouyer Previous Release: 4322 1.1.1.2.2.2 bouyer Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 4323 1.1.1.2.2.2 bouyer Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 4324 1.1.1.2.2.2 bouyer Current Release: 4325 1.1.1.2.2.2 bouyer Non-Debug Version: 76.2K Code, 12.3K Data, 88.5K Total 4326 1.1.1.2.2.2 bouyer Debug Version: 163.0K Code, 67.4K Data, 230.4K Total 4327 1.1.1.2.2.2 bouyer 4328 1.1.1.2.2.2 bouyer 4329 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4330 1.1.1.2.2.2 bouyer 4331 1.1.1.2.2.2 bouyer Fixed a problem with very large initializer lists (more than 4000 elements) 4332 1.1.1.2.2.2 bouyer for both Buffer and Package objects where the parse stack could overflow. 4333 1.1.1.2.2.2 bouyer 4334 1.1.1.2.2.2 bouyer Enhanced the pre-compile source code scan for non-ASCII characters to ignore 4335 1.1.1.2.2.2 bouyer characters within comment fields. The scan is now always performed and is no 4336 1.1.1.2.2.2 bouyer longer optional, detecting invalid characters within a source file 4337 1.1.1.2.2.2 bouyer immediately rather than during the parse phase or later. 4338 1.1.1.2.2.2 bouyer 4339 1.1.1.2.2.2 bouyer Enhanced the ASL grammar definition to force early reductions on all list- 4340 1.1.1.2.2.2 bouyer style grammar elements so that the overall parse stack usage is greatly 4341 1.1.1.2.2.2 bouyer reduced. This should improve performance and reduce the possibility of parse 4342 1.1.1.2.2.2 bouyer stack overflow. 4343 1.1.1.2.2.2 bouyer 4344 1.1.1.2.2.2 bouyer Eliminated all reduce/reduce conflicts in the iASL parser generation. Also, 4345 1.1.1.2.2.2 bouyer with the addition of a %expected statement, the compiler generates from 4346 1.1.1.2.2.2 bouyer source with no warnings. 4347 1.1.1.2.2.2 bouyer 4348 1.1.1.2.2.2 bouyer Fixed a possible segment fault in the disassembler if the input filename 4349 1.1.1.2.2.2 bouyer does not contain a "dot" extension (Thomas Renninger). 4350 1.1.1.2.2.2 bouyer 4351 1.1.1.2.2.2 bouyer ---------------------------------------- 4352 1.1.1.2.2.2 bouyer 21 October 2005. Summary of changes for version 20051021: 4353 1.1.1.2.2.2 bouyer 4354 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4355 1.1.1.2.2.2 bouyer 4356 1.1.1.2.2.2 bouyer Implemented support for the EM64T and other x86-64 processors. This 4357 1.1.1.2.2.2 bouyer essentially entails recognizing that these processors support non-aligned 4358 1.1.1.2.2.2 bouyer memory transfers. Previously, all 64-bit processors were assumed to lack 4359 1.1.1.2.2.2 bouyer hardware support for non-aligned transfers. 4360 1.1.1.2.2.2 bouyer 4361 1.1.1.2.2.2 bouyer Completed conversion of the Resource Manager to nearly full table-driven 4362 1.1.1.2.2.2 bouyer operation. Specifically, the resource conversion code (convert AML to 4363 1.1.1.2.2.2 bouyer internal format and the reverse) and the debug code to dump internal 4364 1.1.1.2.2.2 bouyer resource descriptors are fully table-driven, reducing code and data size and 4365 1.1.1.2.2.2 bouyer improving maintainability. 4366 1.1.1.2.2.2 bouyer 4367 1.1.1.2.2.2 bouyer The OSL interfaces for Acquire and Release Lock now use a 64-bit flag word 4368 1.1.1.2.2.2 bouyer on 64-bit processors instead of a fixed 32-bit word. (With assistance from 4369 1.1.1.2.2.2 bouyer Alexey Starikovskiy) 4370 1.1.1.2.2.2 bouyer 4371 1.1.1.2.2.2 bouyer Implemented support within the resource conversion code for the Type- 4372 1.1.1.2.2.2 bouyer Specific byte within the various ACPI 3.0 *WordSpace macros. 4373 1.1.1.2.2.2 bouyer 4374 1.1.1.2.2.2 bouyer Fixed some issues within the resource conversion code for the type-specific 4375 1.1.1.2.2.2 bouyer flags for both Memory and I/O address resource descriptors. For Memory, 4376 1.1.1.2.2.2 bouyer implemented support for the MTP and TTP flags. For I/O, split the TRS and 4377 1.1.1.2.2.2 bouyer TTP flags into two separate fields. 4378 1.1.1.2.2.2 bouyer 4379 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4380 1.1.1.2.2.2 bouyer subsystem are shown below. These are the code and data sizes for the 4381 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 32-bit compiler. These 4382 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug version of the 4383 1.1.1.2.2.2 bouyer code includes the debug output trace mechanism and has a much larger code 4384 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the efficiency 4385 1.1.1.2.2.2 bouyer of the compiler and the compiler options used during generation. 4386 1.1.1.2.2.2 bouyer 4387 1.1.1.2.2.2 bouyer Previous Release: 4388 1.1.1.2.2.2 bouyer Non-Debug Version: 77.1K Code, 12.1K Data, 89.2K Total 4389 1.1.1.2.2.2 bouyer Debug Version: 168.0K Code, 68.3K Data, 236.3K Total 4390 1.1.1.2.2.2 bouyer Current Release: 4391 1.1.1.2.2.2 bouyer Non-Debug Version: 76.1K Code, 12.2K Data, 88.3K Total 4392 1.1.1.2.2.2 bouyer Debug Version: 163.5K Code, 67.0K Data, 230.5K Total 4393 1.1.1.2.2.2 bouyer 4394 1.1.1.2.2.2 bouyer 4395 1.1.1.2.2.2 bouyer 4396 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4397 1.1.1.2.2.2 bouyer 4398 1.1.1.2.2.2 bouyer Relaxed a compiler restriction that disallowed a ResourceIndex byte if the 4399 1.1.1.2.2.2 bouyer corresponding ResourceSource string was not also present in a resource 4400 1.1.1.2.2.2 bouyer descriptor declaration. This restriction caused problems with existing 4401 1.1.1.2.2.2 bouyer AML/ASL code that includes the Index byte without the string. When such AML 4402 1.1.1.2.2.2 bouyer was disassembled, it could not be compiled without modification. Further, 4403 1.1.1.2.2.2 bouyer the modified code created a resource template with a different size than the 4404 1.1.1.2.2.2 bouyer original, breaking code that used fixed offsets into the resource template 4405 1.1.1.2.2.2 bouyer buffer. 4406 1.1.1.2.2.2 bouyer 4407 1.1.1.2.2.2 bouyer Removed a recent feature of the disassembler to ignore a lone ResourceIndex 4408 1.1.1.2.2.2 bouyer byte.

Summary of changes for version 20050930: 4419 1.1.1.2.2.2 bouyer 4420 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4421 1.1.1.2.2.2 bouyer 4422 1.1.1.2.2.2 bouyer Completed a major overhaul of the Resource Manager code - specifically, 4423 1.1.1.2.2.2 bouyer optimizations in the area of the AML/internal resource conversion code. The 4424 1.1.1.2.2.2 bouyer code has been optimized to simplify and eliminate duplicated code, CPU stack 4425 1.1.1.2.2.2 bouyer use has been decreased by optimizing function parameters and local 4426 1.1.1.2.2.2 bouyer variables, and naming conventions across the manager have been standardized 4427 1.1.1.2.2.2 bouyer for clarity and ease of maintenance (this includes function, parameter, 4428 1.1.1.2.2.2 bouyer variable, and struct/typedef names.) The update may force changes in some 4429 1.1.1.2.2.2 bouyer driver code, depending on how resources are handled by the host OS. 4430 1.1.1.2.2.2 bouyer 4431 1.1.1.2.2.2 bouyer All Resource Manager dispatch and information tables have been moved to a 4432 1.1.1.2.2.2 bouyer single location for clarity and ease of maintenance. One new file was 4433 1.1.1.2.2.2 bouyer created, named "rsinfo.c". 4434 1.1.1.2.2.2 bouyer 4435 1.1.1.2.2.2 bouyer The ACPI return macros (return_ACPI_STATUS, etc.) have been modified to 4436 1.1.1.2.2.2 bouyer guarantee that the argument is not evaluated twice, making them less prone 4437 1.1.1.2.2.2 bouyer to macro side-effects. However, since there exists the possibility of 4438 1.1.1.2.2.2 bouyer additional stack use if a particular compiler cannot optimize them (such as 4439 1.1.1.2.2.2 bouyer in the debug generation case), the original macros are optionally available. 4440 1.1.1.2.2.2 bouyer Note that some invocations of the return_VALUE macro may now cause size 4441 1.1.1.2.2.2 bouyer mismatch warnings; the return_UINT8 and return_UINT32 macros are provided to 4442 1.1.1.2.2.2 bouyer eliminate these. (From Randy Dunlap) 4443 1.1.1.2.2.2 bouyer 4444 1.1.1.2.2.2 bouyer Implemented a new mechanism to enable debug tracing for individual control 4445 1.1.1.2.2.2 bouyer methods. A new external interface, AcpiDebugTrace, is provided to enable 4446 1.1.1.2.2.2 bouyer this mechanism. The intent is to allow the host OS to easily enable and 4447 1.1.1.2.2.2 bouyer disable tracing for problematic control methods. This interface can be 4448 1.1.1.2.2.2 bouyer easily exposed to a user or debugger interface if desired. See the file 4449 1.1.1.2.2.2 bouyer psxface.c for details. 4450 1.1.1.2.2.2 bouyer 4451 1.1.1.2.2.2 bouyer AcpiUtCallocate will now return a valid pointer if a length of zero is 4452 1.1.1.2.2.2 bouyer specified - a length of one is used and a warning is issued. This matches 4453 1.1.1.2.2.2 bouyer the behavior of AcpiUtAllocate. 4454 1.1.1.2.2.2 bouyer 4455 1.1.1.2.2.2 bouyer Code and Data Size: The current and previous library sizes for the core 4456 1.1.1.2.2.2 bouyer subsystem are shown below.

When the issues are fully resolved, the code will be enabled by 4645 1.1.1.2.2.2 bouyer default again. 4646 1.1.1.2.2.2 bouyer 4647 1.1.1.2.2.2 bouyer Modified the internal functions for debug print support to define the 4648 1.1.1.2.2.2 bouyer FunctionName parameter as a (const char *) for compatibility with compiler 4649 1.1.1.2.2.2 bouyer built-in macros such as __FUNCTION__, etc. 4650 1.1.1.2.2.2 bouyer 4651 1.1.1.2.2.2 bouyer Linted the entire ACPICA source tree for both 32-bit and 64-bit. 4652 1.1.1.2.2.2 bouyer 4653 1.1.1.2.2.2 bouyer Implemented support to display an object count summary for the AML Debugger 4654 1.1.1.2.2.2 bouyer commands Object and Methods. 4655 1.1.1.2.2.2 bouyer 4656 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4657 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 4658 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4659 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 4660 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 4661 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 4662 1.1.1.2.2.2 bouyer the compiler options used during generation. 4663 1.1.1.2.2.2 bouyer 4664 1.1.1.2.2.2 bouyer Previous Release: 4665 1.1.1.2.2.2 bouyer Non-Debug Version: 78.6K Code, 11.6K Data, 90.2K Total 4666 1.1.1.2.2.2 bouyer Debug Version: 170.0K Code, 69.7K Data, 239.7K Total 4667 1.1.1.2.2.2 bouyer Current Release: 4668 1.1.1.2.2.2 bouyer Non-Debug Version: 78.6K Code, 11.7K Data, 90.3K Total 4669 1.1.1.2.2.2 bouyer Debug Version: 167.0K Code, 69.9K Data, 236.9K Total 4670 1.1.1.2.2.2 bouyer 4671 1.1.1.2.2.2 bouyer 4672 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4673 1.1.1.2.2.2 bouyer 4674 1.1.1.2.2.2 bouyer Fixed a regression that appeared in the 20050708 version of the compiler 4675 1.1.1.2.2.2 bouyer where an error message was inadvertently emitted for invocations of the _OSI 4676 1.1.1.2.2.2 bouyer reserved control method. 4677 1.1.1.2.2.2 bouyer 4678 1.1.1.2.2.2 bouyer ---------------------------------------- 4679 1.1.1.2.2.2 bouyer 08 July 2005. Summary of changes for version 20050708: 4680 1.1.1.2.2.2 bouyer 4681 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4682 1.1.1.2.2.2 bouyer 4683 1.1.1.2.2.2 bouyer The use of the CPU stack in the debug version of the subsystem has been 4684 1.1.1.2.2.2 bouyer considerably reduced. Previously, a debug structure was declared in every 4685 1.1.1.2.2.2 bouyer function that used the debug macros. This structure has been removed in 4686 1.1.1.2.2.2 bouyer favor of declaring the individual elements as parameters to the debug 4687 1.1.1.2.2.2 bouyer functions. This reduces the cumulative stack use during nested execution of 4688 1.1.1.2.2.2 bouyer ACPI function calls at the cost of a small increase in the code size of the 4689 1.1.1.2.2.2 bouyer debug version of the subsystem. With assistance from Alexey Starikovskiy and 4690 1.1.1.2.2.2 bouyer Len Brown. 4691 1.1.1.2.2.2 bouyer 4692 1.1.1.2.2.2 bouyer Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent 4693 1.1.1.2.2.2 bouyer headers to define a macro that will return the current function name at 4694 1.1.1.2.2.2 bouyer runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by 4695 1.1.1.2.2.2 bouyer the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the 4696 1.1.1.2.2.2 bouyer compiler-dependent header, the function name is saved on the CPU stack (one 4697 1.1.1.2.2.2 bouyer pointer per function.) This mechanism is used because apparently there 4698 1.1.1.2.2.2 bouyer exists no standard ANSI-C defined macro that that returns the function name. 4699 1.1.1.2.2.2 bouyer 4700 1.1.1.2.2.2 bouyer Redesigned and reimplemented the "Owner ID" mechanism used to track 4701 1.1.1.2.2.2 bouyer namespace objects created/deleted by ACPI tables and control method 4702 1.1.1.2.2.2 bouyer execution. A bitmap is now used to allocate and free the IDs, thus solving 4703 1.1.1.2.2.2 bouyer the wraparound problem present in the previous implementation. The size of 4704 1.1.1.2.2.2 bouyer the namespace node descriptor was reduced by 2 bytes as a result (Alexey 4705 1.1.1.2.2.2 bouyer Starikovskiy). 4706 1.1.1.2.2.2 bouyer 4707 1.1.1.2.2.2 bouyer Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield 4708 1.1.1.2.2.2 bouyer flag definitions within the headers for the predefined ACPI tables. These 4709 1.1.1.2.2.2 bouyer have been replaced by UINT8_BIT in order to increase the code portability of 4710 1.1.1.2.2.2 bouyer the subsystem. If the use of UINT8 remains a problem, we may be forced to 4711 1.1.1.2.2.2 bouyer eliminate bitfields entirely because of a lack of portability. 4712 1.1.1.2.2.2 bouyer 4713 1.1.1.2.2.2 bouyer Enhanced the performance of the AcpiUtUpdateObjectReference procedure. This 4714 1.1.1.2.2.2 bouyer is a frequently used function and this improvement increases the performance 4715 1.1.1.2.2.2 bouyer of the entire subsystem (Alexey Starikovskiy). 4716 1.1.1.2.2.2 bouyer 4717 1.1.1.2.2.2 bouyer Fixed several possible memory leaks and the inverse - premature object 4718 1.1.1.2.2.2 bouyer deletion (Alexey Starikovskiy). 4719 1.1.1.2.2.2 bouyer 4720 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4721 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 4722 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4723 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 4724 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 4725 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 4726 1.1.1.2.2.2 bouyer the compiler options used during generation. 4727 1.1.1.2.2.2 bouyer 4728 1.1.1.2.2.2 bouyer Previous Release: 4729 1.1.1.2.2.2 bouyer Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total 4730 1.1.1.2.2.2 bouyer Debug Version: 165.2K Code, 69.6K Data, 234.8K Total 4731 1.1.1.2.2.2 bouyer Current Release: 4732 1.1.1.2.2.2 bouyer Non-Debug Version: 78.6K Code, 11.6K Data, 90.2K Total 4733 1.1.1.2.2.2 bouyer Debug Version: 170.0K Code, 69.7K Data, 239.7K Total 4734 1.1.1.2.2.2 bouyer 4735 1.1.1.2.2.2 bouyer ---------------------------------------- 4736 1.1.1.2.2.2 bouyer 24 June 2005. Summary of changes for version 20050624: 4737 1.1.1.2.2.2 bouyer 4738 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4739 1.1.1.2.2.2 bouyer 4740 1.1.1.2.2.2 bouyer Modified the new OSL cache interfaces to use ACPI_CACHE_T as the type for 4741 1.1.1.2.2.2 bouyer the host-defined cache object. This allows the OSL implementation to define 4742 1.1.1.2.2.2 bouyer and type this object in any manner desired, simplifying the OSL 4743 1.1.1.2.2.2 bouyer implementation. For example, ACPI_CACHE_T is defined as kmem_cache_t for 4744 1.1.1.2.2.2 bouyer Linux, and should be defined in the OS-specific header file for other 4745 1.1.1.2.2.2 bouyer operating systems as required. 4746 1.1.1.2.2.2 bouyer 4747 1.1.1.2.2.2 bouyer Changed the interface to AcpiOsAcquireObject to directly return the 4748 1.1.1.2.2.2 bouyer requested object as the function return (instead of ACPI_STATUS.) This 4749 1.1.1.2.2.2 bouyer change was made for performance reasons, since this is the purpose of the 4750 1.1.1.2.2.2 bouyer interface in the first place. AcpiOsAcquireObject is now similar to the 4751 1.1.1.2.2.2 bouyer AcpiOsAllocate interface. 4752 1.1.1.2.2.2 bouyer 4753 1.1.1.2.2.2 bouyer Implemented a new AML debugger command named Businfo. This command displays 4754 1.1.1.2.2.2 bouyer information about all devices that have an associate _PRT object. The _ADR, 4755 1.1.1.2.2.2 bouyer _HID, _UID, and _CID are displayed for these devices. 4756 1.1.1.2.2.2 bouyer 4757 1.1.1.2.2.2 bouyer Modified the initialization sequence in AcpiInitializeSubsystem to call the 4758 1.1.1.2.2.2 bouyer OSL interface AcpiOslInitialize first, before any local initialization. This 4759 1.1.1.2.2.2 bouyer change was required because the global initialization now calls OSL 4760 1.1.1.2.2.2 bouyer interfaces. 4761 1.1.1.2.2.2 bouyer 4762 1.1.1.2.2.2 bouyer Enhanced the Dump command to display the entire contents of Package objects 4763 1.1.1.2.2.2 bouyer (including all sub-objects and their values.) 4764 1.1.1.2.2.2 bouyer 4765 1.1.1.2.2.2 bouyer Restructured the code base to split some files because of size and/or 4766 1.1.1.2.2.2 bouyer because the code logically belonged in a separate file. New files are listed 4767 1.1.1.2.2.2 bouyer below. All makefiles and project files included in the ACPI CA release have 4768 1.1.1.2.2.2 bouyer been updated. 4769 1.1.1.2.2.2 bouyer utilities/utcache.c /* Local cache interfaces */ 4770 1.1.1.2.2.2 bouyer utilities/utmutex.c /* Local mutex support */ 4771 1.1.1.2.2.2 bouyer utilities/utstate.c /* State object support */ 4772 1.1.1.2.2.2 bouyer interpreter/parser/psloop.c /* Main AML parse loop */ 4773 1.1.1.2.2.2 bouyer 4774 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4775 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 4776 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4777 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 4778 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 4779 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 4780 1.1.1.2.2.2 bouyer the compiler options used during generation. 4781 1.1.1.2.2.2 bouyer 4782 1.1.1.2.2.2 bouyer Previous Release: 4783 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 4784 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 4785 1.1.1.2.2.2 bouyer Current Release: 4786 1.1.1.2.2.2 bouyer Non-Debug Version: 78.6K Code, 11.5K Data, 90.1K Total 4787 1.1.1.2.2.2 bouyer Debug Version: 165.2K Code, 69.6K Data, 234.8K Total 4788 1.1.1.2.2.2 bouyer 4789 1.1.1.2.2.2 bouyer 4790 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4791 1.1.1.2.2.2 bouyer 4792 1.1.1.2.2.2 bouyer Fixed a regression introduced in version 20050513 where the use of a Package 4793 1.1.1.2.2.2 bouyer object within a Case() statement caused a compile time exception. The 4794 1.1.1.2.2.2 bouyer original behavior has been restored (a Match() operator is emitted.) 4795 1.1.1.2.2.2 bouyer 4796 1.1.1.2.2.2 bouyer ---------------------------------------- 4797 1.1.1.2.2.2 bouyer 17 June 2005. Summary of changes for version 20050617: 4798 1.1.1.2.2.2 bouyer 4799 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4800 1.1.1.2.2.2 bouyer 4801 1.1.1.2.2.2 bouyer Moved the object cache operations into the OS interface layer (OSL) to allow 4802 1.1.1.2.2.2 bouyer the host OS to handle these operations if desired (for example, the Linux 4803 1.1.1.2.2.2 bouyer OSL will invoke the slab allocator). This support is optional; the compile 4804 1.1.1.2.2.2 bouyer time define ACPI_USE_LOCAL_CACHE may be used to utilize the original cache 4805 1.1.1.2.2.2 bouyer code in the ACPI CA core. The new OSL interfaces are shown below. See 4806 1.1.1.2.2.2 bouyer utalloc.c for an example implementation, and acpiosxf.h for the exact 4807 1.1.1.2.2.2 bouyer interface definitions.

This fits better with many OS lock models. 4816 1.1.1.2.2.2 bouyer Note: the current execution state (interrupt handler or not) is no longer 4817 1.1.1.2.2.2 bouyer passed to these interfaces. If necessary, the OSL must determine this state 4818 1.1.1.2.2.2 bouyer by itself, a simple and fast operation. With assistance from Alexey 4819 1.1.1.2.2.2 bouyer Starikovskiy. 4820 1.1.1.2.2.2 bouyer 4821 1.1.1.2.2.2 bouyer Fixed a problem in the ACPI table handling where a valid XSDT was assumed 4822 1.1.1.2.2.2 bouyer present if the revision of the RSDP was 2 or greater. According to the ACPI 4823 1.1.1.2.2.2 bouyer specification, the XSDT is optional in all cases, and the table manager 4824 1.1.1.2.2.2 bouyer therefore now checks for both an RSDP >=2 and a valid XSDT pointer. 4825 1.1.1.2.2.2 bouyer Otherwise, the RSDT pointer is used. Some ACPI 2.0 compliant BIOSs contain 4826 1.1.1.2.2.2 bouyer only the RSDT. 4827 1.1.1.2.2.2 bouyer 4828 1.1.1.2.2.2 bouyer Fixed an interpreter problem with the Mid() operator in the case of an input 4829 1.1.1.2.2.2 bouyer string where the resulting output string is of zero length. It now correctly 4830 1.1.1.2.2.2 bouyer returns a valid, null terminated string object instead of a string object 4831 1.1.1.2.2.2 bouyer with a null pointer. 4832 1.1.1.2.2.2 bouyer 4833 1.1.1.2.2.2 bouyer Fixed a problem with the control method argument handling to allow a store 4834 1.1.1.2.2.2 bouyer to an Arg object that already contains an object of type Device. The Device 4835 1.1.1.2.2.2 bouyer object is now correctly overwritten. Previously, an error was returned. 4836 1.1.1.2.2.2 bouyer 4837 1.1.1.2.2.2 bouyer 4838 1.1.1.2.2.2 bouyer Enhanced the debugger Find command to emit object values in addition to the 4839 1.1.1.2.2.2 bouyer found object pathnames. The output format is the same as the dump namespace 4840 1.1.1.2.2.2 bouyer command. 4841 1.1.1.2.2.2 bouyer 4842 1.1.1.2.2.2 bouyer Enhanced the debugger Set command. It now has the ability to set the value 4843 1.1.1.2.2.2 bouyer of any Named integer object in the namespace (Previously, only method locals 4844 1.1.1.2.2.2 bouyer and args could be set.) 4845 1.1.1.2.2.2 bouyer 4846 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4847 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 4848 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4849 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 4850 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 4851 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 4852 1.1.1.2.2.2 bouyer the compiler options used during generation. 4853 1.1.1.2.2.2 bouyer 4854 1.1.1.2.2.2 bouyer Previous Release: 4855 1.1.1.2.2.2 bouyer Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 4856 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 4857 1.1.1.2.2.2 bouyer Current Release: 4858 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.6K Data, 89.9K Total 4859 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 69.1K Data, 233.1K Total 4860 1.1.1.2.2.2 bouyer 4861 1.1.1.2.2.2 bouyer 4862 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4863 1.1.1.2.2.2 bouyer 4864 1.1.1.2.2.2 bouyer Fixed a regression in the disassembler where if/else/while constructs were 4865 1.1.1.2.2.2 bouyer output incorrectly. This problem was introduced in the previous release 4866 1.1.1.2.2.2 bouyer (20050526). This problem also affected the single-step disassembly in the 4867 1.1.1.2.2.2 bouyer debugger. 4868 1.1.1.2.2.2 bouyer 4869 1.1.1.2.2.2 bouyer Fixed a problem where compiling the reserved _OSI method would randomly (but 4870 1.1.1.2.2.2 bouyer rarely) produce compile errors. 4871 1.1.1.2.2.2 bouyer 4872 1.1.1.2.2.2 bouyer Enhanced the disassembler to emit compilable code in the face of incorrect 4873 1.1.1.2.2.2 bouyer AML resource descriptors. If the optional ResourceSourceIndex is present, 4874 1.1.1.2.2.2 bouyer but the ResourceSource is not, do not emit the ResourceSourceIndex in the 4875 1.1.1.2.2.2 bouyer disassembly. Otherwise, the resulting code cannot be compiled without 4876 1.1.1.2.2.2 bouyer errors. 4877 1.1.1.2.2.2 bouyer 4878 1.1.1.2.2.2 bouyer ---------------------------------------- 4879 1.1.1.2.2.2 bouyer 26 May 2005. Summary of changes for version 20050526: 4880 1.1.1.2.2.2 bouyer 4881 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4882 1.1.1.2.2.2 bouyer 4883 1.1.1.2.2.2 bouyer Implemented support to execute Type 1 and Type 2 AML opcodes appearing at 4884 1.1.1.2.2.2 bouyer the module level (not within a control method.) These opcodes are executed 4885 1.1.1.2.2.2 bouyer exactly once at the time the table is loaded. This type of code was legal up 4886 1.1.1.2.2.2 bouyer until the release of ACPI 2.0B (2002) and is now supported within ACPI CA in 4887 1.1.1.2.2.2 bouyer order to provide backwards compatibility with earlier BIOS implementations. 4888 1.1.1.2.2.2 bouyer This eliminates the "Encountered executable code at module level" warning 4889 1.1.1.2.2.2 bouyer that was previously generated upon detection of such code. 4890 1.1.1.2.2.2 bouyer 4891 1.1.1.2.2.2 bouyer Fixed a problem in the interpreter where an AE_NOT_FOUND exception could 4892 1.1.1.2.2.2 bouyer inadvertently be generated during the lookup of namespace objects in the 4893 1.1.1.2.2.2 bouyer second pass parse of ACPI tables and control methods. It appears that this 4894 1.1.1.2.2.2 bouyer problem could occur during the resolution of forward references to namespace 4895 1.1.1.2.2.2 bouyer objects. 4896 1.1.1.2.2.2 bouyer 4897 1.1.1.2.2.2 bouyer Added the ACPI_MUTEX_DEBUG #ifdef to the AcpiUtReleaseMutex function, 4898 1.1.1.2.2.2 bouyer corresponding to the same #ifdef in the AcpiUtAcquireMutex function. This 4899 1.1.1.2.2.2 bouyer allows the deadlock detection debug code to be compiled out in the normal 4900 1.1.1.2.2.2 bouyer case, improving mutex performance (and overall subsystem performance) 4901 1.1.1.2.2.2 bouyer considerably. 4902 1.1.1.2.2.2 bouyer 4903 1.1.1.2.2.2 bouyer Implemented a handful of miscellaneous fixes for possible memory leaks on 4904 1.1.1.2.2.2 bouyer error conditions and error handling control paths. These fixes were 4905 1.1.1.2.2.2 bouyer suggested by FreeBSD and the Coverity Prevent source code analysis tool. 4906 1.1.1.2.2.2 bouyer 4907 1.1.1.2.2.2 bouyer Added a check for a null RSDT pointer in AcpiGetFirmwareTable (tbxfroot.c) 4908 1.1.1.2.2.2 bouyer to prevent a fault in this error case. 4909 1.1.1.2.2.2 bouyer 4910 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4911 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 4912 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 4913 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 4914 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 4915 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 4916 1.1.1.2.2.2 bouyer the compiler options used during generation. 4917 1.1.1.2.2.2 bouyer 4918 1.1.1.2.2.2 bouyer Previous Release: 4919 1.1.1.2.2.2 bouyer Non-Debug Version: 78.2K Code, 11.6K Data, 89.8K Total 4920 1.1.1.2.2.2 bouyer Debug Version: 163.7K Code, 69.3K Data, 233.0K Total 4921 1.1.1.2.2.2 bouyer Current Release: 4922 1.1.1.2.2.2 bouyer Non-Debug Version: 78.1K Code, 11.6K Data, 89.7K Total 4923 1.1.1.2.2.2 bouyer Debug Version: 164.0K Code, 69.3K Data, 233.3K Total 4924 1.1.1.2.2.2 bouyer 4925 1.1.1.2.2.2 bouyer 4926 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 4927 1.1.1.2.2.2 bouyer 4928 1.1.1.2.2.2 bouyer Implemented support to allow Type 1 and Type 2 ASL operators to appear at 4929 1.1.1.2.2.2 bouyer the module level (not within a control method.) These operators will be 4930 1.1.1.2.2.2 bouyer executed once at the time the table is loaded. This type of code was legal 4931 1.1.1.2.2.2 bouyer up until the release of ACPI 2.0B (2002) and is now supported by the iASL 4932 1.1.1.2.2.2 bouyer compiler in order to provide backwards compatibility with earlier BIOS ASL 4933 1.1.1.2.2.2 bouyer code. 4934 1.1.1.2.2.2 bouyer 4935 1.1.1.2.2.2 bouyer The ACPI integer width (specified via the table revision ID or the -r 4936 1.1.1.2.2.2 bouyer override, 32 or 64 bits) is now used internally during compile-time constant 4937 1.1.1.2.2.2 bouyer folding to ensure that constants are truncated to 32 bits if necessary. 4938 1.1.1.2.2.2 bouyer Previously, the revision ID value was only emitted in the AML table header. 4939 1.1.1.2.2.2 bouyer 4940 1.1.1.2.2.2 bouyer An error message is now generated for the Mutex and Method operators if the 4941 1.1.1.2.2.2 bouyer SyncLevel parameter is outside the legal range of 0 through 15. 4942 1.1.1.2.2.2 bouyer 4943 1.1.1.2.2.2 bouyer Fixed a problem with the Method operator ParameterTypes list handling (ACPI 4944 1.1.1.2.2.2 bouyer 3.0). Previously, more than 2 types or 2 arguments generated a syntax error. 4945 1.1.1.2.2.2 bouyer The actual underlying implementation of method argument typechecking is 4946 1.1.1.2.2.2 bouyer still under development, however. 4947 1.1.1.2.2.2 bouyer 4948 1.1.1.2.2.2 bouyer ---------------------------------------- 4949 1.1.1.2.2.2 bouyer 13 May 2005. Summary of changes for version 20050513: 4950 1.1.1.2.2.2 bouyer 4951 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 4952 1.1.1.2.2.2 bouyer 4953 1.1.1.2.2.2 bouyer Implemented support for PCI Express root bridges -- added support for device 4954 1.1.1.2.2.2 bouyer PNP0A08 in the root bridge search within AcpiEvPciConfigRegionSetup. 4955 1.1.1.2.2.2 bouyer 4956 1.1.1.2.2.2 bouyer The interpreter now automatically truncates incoming 64-bit constants to 32 4957 1.1.1.2.2.2 bouyer bits if currently executing out of a 32-bit ACPI table (Revision < 2). This 4958 1.1.1.2.2.2 bouyer also affects the iASL compiler constant folding. (Note: as per below, the 4959 1.1.1.2.2.2 bouyer iASL compiler no longer allows 64-bit constants within 32-bit tables.) 4960 1.1.1.2.2.2 bouyer 4961 1.1.1.2.2.2 bouyer Fixed a problem where string and buffer objects with "static" pointers 4962 1.1.1.2.2.2 bouyer (pointers to initialization data within an ACPI table) were not handled 4963 1.1.1.2.2.2 bouyer consistently. The internal object copy operation now always copies the data 4964 1.1.1.2.2.2 bouyer to a newly allocated buffer, regardless of whether the source object is 4965 1.1.1.2.2.2 bouyer static or not. 4966 1.1.1.2.2.2 bouyer 4967 1.1.1.2.2.2 bouyer Fixed a problem with the FromBCD operator where an implicit result 4968 1.1.1.2.2.2 bouyer conversion was improperly performed while storing the result to the target 4969 1.1.1.2.2.2 bouyer operand. Since this is an "explicit conversion" operator, the implicit 4970 1.1.1.2.2.2 bouyer conversion should never be performed on the output. 4971 1.1.1.2.2.2 bouyer 4972 1.1.1.2.2.2 bouyer Fixed a problem with the CopyObject operator where a copy to an existing 4973 1.1.1.2.2.2 bouyer named object did not always completely overwrite the existing object stored 4974 1.1.1.2.2.2 bouyer at name. Specifically, a buffer-to-buffer copy did not delete the existing 4975 1.1.1.2.2.2 bouyer buffer. 4976 1.1.1.2.2.2 bouyer 4977 1.1.1.2.2.2 bouyer Replaced "InterruptLevel" with "InterruptNumber" in all GPE interfaces and 4978 1.1.1.2.2.2 bouyer structs for consistency. 4979 1.1.1.2.2.2 bouyer 4980 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 4981 1.1.1.2.2.2 bouyer shown below.

The integer 5000 1.1.1.2.2.2 bouyer is truncated to 32 bits. 5001 1.1.1.2.2.2 bouyer 5002 1.1.1.2.2.2 bouyer Fixed a problem with large package objects: if the static length of the 5003 1.1.1.2.2.2 bouyer package is greater than 255, the "variable length package" opcode is 5004 1.1.1.2.2.2 bouyer emitted. Previously, this caused an error. This requires an update to the 5005 1.1.1.2.2.2 bouyer ACPI spec, since it currently (incorrectly) states that packages larger than 5006 1.1.1.2.2.2 bouyer 255 elements are not allowed. 5007 1.1.1.2.2.2 bouyer 5008 1.1.1.2.2.2 bouyer The disassembler now correctly handles variable length packages and packages 5009 1.1.1.2.2.2 bouyer larger than 255 elements. 5010 1.1.1.2.2.2 bouyer 5011 1.1.1.2.2.2 bouyer ---------------------------------------- 5012 1.1.1.2.2.2 bouyer 08 April 2005. Summary of changes for version 20050408: 5013 1.1.1.2.2.2 bouyer 5014 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5015 1.1.1.2.2.2 bouyer 5016 1.1.1.2.2.2 bouyer Fixed three cases in the interpreter where an "index" argument to an ASL 5017 1.1.1.2.2.2 bouyer function was still (internally) 32 bits instead of the required 64 bits. 5018 1.1.1.2.2.2 bouyer This was the Index argument to the Index, Mid, and Match operators. 5019 1.1.1.2.2.2 bouyer 5020 1.1.1.2.2.2 bouyer The "strupr" function is now permanently local (AcpiUtStrupr), since this is 5021 1.1.1.2.2.2 bouyer not a POSIX-defined function and not present in most kernel-level C 5022 1.1.1.2.2.2 bouyer libraries. All references to the C library strupr function have been removed 5023 1.1.1.2.2.2 bouyer from the headers. 5024 1.1.1.2.2.2 bouyer 5025 1.1.1.2.2.2 bouyer Completed the deployment of static functions/prototypes. All prototypes with 5026 1.1.1.2.2.2 bouyer the static attribute have been moved from the headers to the owning C file. 5027 1.1.1.2.2.2 bouyer 5028 1.1.1.2.2.2 bouyer Implemented an extract option (-e) for the AcpiBin utility (AML binary 5029 1.1.1.2.2.2 bouyer utility). This option allows the utility to extract individual ACPI tables 5030 1.1.1.2.2.2 bouyer from the output of AcpiDmp. It provides the same functionality of the 5031 1.1.1.2.2.2 bouyer acpixtract.pl perl script without the worry of setting the correct perl 5032 1.1.1.2.2.2 bouyer options. AcpiBin runs on Windows and has not yet been generated/validated in 5033 1.1.1.2.2.2 bouyer the Linux/Unix environment (but should be soon). 5034 1.1.1.2.2.2 bouyer 5035 1.1.1.2.2.2 bouyer Updated and fixed the table dump option for AcpiBin (-d). This option 5036 1.1.1.2.2.2 bouyer converts a single ACPI table to a hex/ascii file, similar to the output of 5037 1.1.1.2.2.2 bouyer AcpiDmp. 5038 1.1.1.2.2.2 bouyer 5039 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5040 1.1.1.2.2.2 bouyer shown below.

This indicates some kind of file or table corruption. 5060 1.1.1.2.2.2 bouyer 5061 1.1.1.2.2.2 bouyer ---------------------------------------- 5062 1.1.1.2.2.2 bouyer 29 March 2005. Summary of changes for version 20050329: 5063 1.1.1.2.2.2 bouyer 5064 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5065 1.1.1.2.2.2 bouyer 5066 1.1.1.2.2.2 bouyer An error is now generated if an attempt is made to create a Buffer Field of 5067 1.1.1.2.2.2 bouyer length zero (A CreateField with a length operand of zero.) 5068 1.1.1.2.2.2 bouyer 5069 1.1.1.2.2.2 bouyer The interpreter now issues a warning whenever executable code at the module 5070 1.1.1.2.2.2 bouyer level is detected during ACPI table load. This will give some idea of the 5071 1.1.1.2.2.2 bouyer prevalence of this type of code. 5072 1.1.1.2.2.2 bouyer 5073 1.1.1.2.2.2 bouyer Implemented support for references to named objects (other than control 5074 1.1.1.2.2.2 bouyer methods) within package objects. 5075 1.1.1.2.2.2 bouyer 5076 1.1.1.2.2.2 bouyer Enhanced package object output for the debug object. Package objects are now 5077 1.1.1.2.2.2 bouyer completely dumped, showing all elements. 5078 1.1.1.2.2.2 bouyer 5079 1.1.1.2.2.2 bouyer Enhanced miscellaneous object output for the debug object. Any object can 5080 1.1.1.2.2.2 bouyer now be written to the debug object (for example, a device object can be 5081 1.1.1.2.2.2 bouyer written, and the type of the object will be displayed.) 5082 1.1.1.2.2.2 bouyer 5083 1.1.1.2.2.2 bouyer The "static" qualifier has been added to all local functions across both the 5084 1.1.1.2.2.2 bouyer core subsystem and the iASL compiler. 5085 1.1.1.2.2.2 bouyer 5086 1.1.1.2.2.2 bouyer The number of "long" lines (> 80 chars) within the source has been 5087 1.1.1.2.2.2 bouyer significantly reduced, by about 1/3. 5088 1.1.1.2.2.2 bouyer 5089 1.1.1.2.2.2 bouyer Cleaned up all header files to ensure that all CA/iASL functions are 5090 1.1.1.2.2.2 bouyer prototyped (even static functions) and the formatting is consistent. 5091 1.1.1.2.2.2 bouyer 5092 1.1.1.2.2.2 bouyer Two new header files have been added, acopcode.h and acnames.h. 5093 1.1.1.2.2.2 bouyer 5094 1.1.1.2.2.2 bouyer Removed several obsolete functions that were no longer used. 5095 1.1.1.2.2.2 bouyer 5096 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5097 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 5098 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5099 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 5100 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5101 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5102 1.1.1.2.2.2 bouyer the compiler options used during generation. 5103 1.1.1.2.2.2 bouyer 5104 1.1.1.2.2.2 bouyer Previous Release: 5105 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5106 1.1.1.2.2.2 bouyer Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 5107 1.1.1.2.2.2 bouyer Current Release: 5108 1.1.1.2.2.2 bouyer Non-Debug Version: 78.0K Code, 11.6K Data, 89.6K Total 5109 1.1.1.2.2.2 bouyer Debug Version: 163.5K Code, 69.3K Data, 232.8K Total 5110 1.1.1.2.2.2 bouyer 5111 1.1.1.2.2.2 bouyer 5112 1.1.1.2.2.2 bouyer 5113 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 5114 1.1.1.2.2.2 bouyer 5115 1.1.1.2.2.2 bouyer Fixed a problem with the resource descriptor generation/support. For the 5116 1.1.1.2.2.2 bouyer ResourceSourceIndex and the ResourceSource fields, both must be present, or 5117 1.1.1.2.2.2 bouyer both must be not present - can't have one without the other. 5118 1.1.1.2.2.2 bouyer 5119 1.1.1.2.2.2 bouyer The compiler now returns non-zero from the main procedure if any errors have 5120 1.1.1.2.2.2 bouyer occurred during the compilation. 5121 1.1.1.2.2.2 bouyer 5122 1.1.1.2.2.2 bouyer 5123 1.1.1.2.2.2 bouyer ---------------------------------------- 5124 1.1.1.2.2.2 bouyer 09 March 2005. Summary of changes for version 20050309: 5125 1.1.1.2.2.2 bouyer 5126 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5127 1.1.1.2.2.2 bouyer 5128 1.1.1.2.2.2 bouyer The string-to-buffer implicit conversion code has been modified again after 5129 1.1.1.2.2.2 bouyer a change to the ACPI specification. In order to match the behavior of the 5130 1.1.1.2.2.2 bouyer other major ACPI implementation, the target buffer is no longer truncated if 5131 1.1.1.2.2.2 bouyer the source string is smaller than an existing target buffer. This change 5132 1.1.1.2.2.2 bouyer requires an update to the ACPI spec, and should eliminate the recent 5133 1.1.1.2.2.2 bouyer AE_AML_BUFFER_LIMIT issues. 5134 1.1.1.2.2.2 bouyer 5135 1.1.1.2.2.2 bouyer The "implicit return" support was rewritten to a new algorithm that solves 5136 1.1.1.2.2.2 bouyer the general case. Rather than attempt to determine when a method is about to 5137 1.1.1.2.2.2 bouyer exit, the result of every ASL operator is saved momentarily until the very 5138 1.1.1.2.2.2 bouyer next ASL operator is executed. Therefore, no matter how the method exits, 5139 1.1.1.2.2.2 bouyer there will always be a saved implicit return value. This feature is only 5140 1.1.1.2.2.2 bouyer enabled with the AcpiGbl_EnableInterpreterSlack flag, and should eliminate 5141 1.1.1.2.2.2 bouyer AE_AML_NO_RETURN_VALUE errors when enabled. 5142 1.1.1.2.2.2 bouyer 5143 1.1.1.2.2.2 bouyer Implemented implicit conversion support for the predicate (operand) of the 5144 1.1.1.2.2.2 bouyer If, Else, and While operators. String and Buffer arguments are automatically 5145 1.1.1.2.2.2 bouyer converted to Integers. 5146 1.1.1.2.2.2 bouyer 5147 1.1.1.2.2.2 bouyer Changed the string-to-integer conversion behavior to match the new ACPI 5148 1.1.1.2.2.2 bouyer errata: "If no integer object exists, a new integer is created. The ASCII 5149 1.1.1.2.2.2 bouyer string is interpreted as a hexadecimal constant. Each string character is 5150 1.1.1.2.2.2 bouyer interpreted as a hexadecimal value ('0'-'9', 'A'-'F', 'a', 'f'), starting 5151 1.1.1.2.2.2 bouyer with the first character as the most significant digit, and ending with the 5152 1.1.1.2.2.2 bouyer first non-hexadecimal character or end-of-string." This means that the first 5153 1.1.1.2.2.2 bouyer non-hex character terminates the conversion and this is the code that was 5154 1.1.1.2.2.2 bouyer changed. 5155 1.1.1.2.2.2 bouyer 5156 1.1.1.2.2.2 bouyer Fixed a problem where the ObjectType operator would fail (fault) when used 5157 1.1.1.2.2.2 bouyer on an Index of a Package which pointed to a null package element. The 5158 1.1.1.2.2.2 bouyer operator now properly returns zero (Uninitialized) in this case. 5159 1.1.1.2.2.2 bouyer 5160 1.1.1.2.2.2 bouyer Fixed a problem where the While operator used excessive memory by not 5161 1.1.1.2.2.2 bouyer properly popping the result stack during execution. There was no memory leak 5162 1.1.1.2.2.2 bouyer after execution, however. (Code provided by Valery Podrezov.) 5163 1.1.1.2.2.2 bouyer 5164 1.1.1.2.2.2 bouyer Fixed a problem where references to control methods within Package objects 5165 1.1.1.2.2.2 bouyer caused the method to be invoked, instead of producing a reference object 5166 1.1.1.2.2.2 bouyer pointing to the method. 5167 1.1.1.2.2.2 bouyer 5168 1.1.1.2.2.2 bouyer Restructured and simplified the pswalk.c module (AcpiPsDeleteParseTree) to 5169 1.1.1.2.2.2 bouyer improve performance and reduce code size.

These are the code and data sizes for the acpica.lib produced 5174 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5175 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 5176 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5177 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5178 1.1.1.2.2.2 bouyer the compiler options used during generation. 5179 1.1.1.2.2.2 bouyer 5180 1.1.1.2.2.2 bouyer Previous Release: 5181 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5182 1.1.1.2.2.2 bouyer Debug Version: 165.4K Code, 69.6K Data, 236.0K Total 5183 1.1.1.2.2.2 bouyer Current Release: 5184 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5185 1.1.1.2.2.2 bouyer Debug Version: 165.4K Code, 69.7K Data, 236.1K Total 5186 1.1.1.2.2.2 bouyer 5187 1.1.1.2.2.2 bouyer 5188 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 5189 1.1.1.2.2.2 bouyer 5190 1.1.1.2.2.2 bouyer Fixed a problem with the Return operator with no arguments. Since the AML 5191 1.1.1.2.2.2 bouyer grammar for the byte encoding requires an operand for the Return opcode, the 5192 1.1.1.2.2.2 bouyer compiler now emits a Return(Zero) for this case. An ACPI specification 5193 1.1.1.2.2.2 bouyer update has been written for this case. 5194 1.1.1.2.2.2 bouyer 5195 1.1.1.2.2.2 bouyer For tables other than the DSDT, namepath optimization is automatically 5196 1.1.1.2.2.2 bouyer disabled. This is because SSDTs can be loaded anywhere in the namespace, the 5197 1.1.1.2.2.2 bouyer compiler has no knowledge of where, and thus cannot optimize namepaths. 5198 1.1.1.2.2.2 bouyer 5199 1.1.1.2.2.2 bouyer Added "ProcessorObj" to the ObjectTypeKeyword list. This object type was 5200 1.1.1.2.2.2 bouyer inadvertently omitted from the ACPI specification, and will require an 5201 1.1.1.2.2.2 bouyer update to the spec. 5202 1.1.1.2.2.2 bouyer 5203 1.1.1.2.2.2 bouyer The source file scan for ASCII characters is now optional (-a). This change 5204 1.1.1.2.2.2 bouyer was made because some vendors place non-ascii characters within comments. 5205 1.1.1.2.2.2 bouyer However, the scan is simply a brute-force byte compare to ensure all 5206 1.1.1.2.2.2 bouyer characters in the file are in the range 0x00 to 0x7F. 5207 1.1.1.2.2.2 bouyer 5208 1.1.1.2.2.2 bouyer Fixed a problem with the CondRefOf operator where the compiler was 5209 1.1.1.2.2.2 bouyer inappropriately checking for the existence of the target. Since the point of 5210 1.1.1.2.2.2 bouyer the operator is to check for the existence of the target at run-time, the 5211 1.1.1.2.2.2 bouyer compiler no longer checks for the target existence. 5212 1.1.1.2.2.2 bouyer 5213 1.1.1.2.2.2 bouyer Fixed a problem where errors generated from the internal AML interpreter 5214 1.1.1.2.2.2 bouyer during constant folding were not handled properly, causing a fault. 5215 1.1.1.2.2.2 bouyer 5216 1.1.1.2.2.2 bouyer Fixed a problem with overly aggressive range checking for the Stall 5217 1.1.1.2.2.2 bouyer operator. The valid range (max 255) is now only checked if the operand is of 5218 1.1.1.2.2.2 bouyer type Integer. All other operand types cannot be statically checked. 5219 1.1.1.2.2.2 bouyer 5220 1.1.1.2.2.2 bouyer Fixed a problem where control method references within the RefOf, DeRefOf, 5221 1.1.1.2.2.2 bouyer and ObjectType operators were not treated properly. They are now treated as 5222 1.1.1.2.2.2 bouyer actual references, not method invocations. 5223 1.1.1.2.2.2 bouyer 5224 1.1.1.2.2.2 bouyer Fixed and enhanced the "list namespace" option (-ln).

This means that Index() cannot be 5289 1.1.1.2.2.2 bouyer a type3 opcode and this will require an update to the ACPI specification. 5290 1.1.1.2.2.2 bouyer 5291 1.1.1.2.2.2 bouyer Disassembler: Implemented support for the TTP, MTP, and TRS resource 5292 1.1.1.2.2.2 bouyer descriptor fields. These fields were inadvertently ignored and not output in 5293 1.1.1.2.2.2 bouyer the disassembly of the resource descriptor. 5294 1.1.1.2.2.2 bouyer 5295 1.1.1.2.2.2 bouyer 5296 1.1.1.2.2.2 bouyer ---------------------------------------- 5297 1.1.1.2.2.2 bouyer 11 February 2005. Summary of changes for version 20050211: 5298 1.1.1.2.2.2 bouyer 5299 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5300 1.1.1.2.2.2 bouyer 5301 1.1.1.2.2.2 bouyer Implemented ACPI 3.0 support for implicit conversion within the Match() 5302 1.1.1.2.2.2 bouyer operator. MatchObjects can now be of type integer, buffer, or string instead 5303 1.1.1.2.2.2 bouyer of just type integer. Package elements are implicitly converted to the type 5304 1.1.1.2.2.2 bouyer of the MatchObject. This change aligns the behavior of Match() with the 5305 1.1.1.2.2.2 bouyer behavior of the other logical operators (LLess(), etc.) It also requires an 5306 1.1.1.2.2.2 bouyer errata change to the ACPI specification as this support was intended for 5307 1.1.1.2.2.2 bouyer ACPI 3.0, but was inadvertently omitted. 5308 1.1.1.2.2.2 bouyer 5309 1.1.1.2.2.2 bouyer Fixed a problem with the internal implicit "to buffer" conversion. Strings 5310 1.1.1.2.2.2 bouyer that are converted to buffers will cause buffer truncation if the string is 5311 1.1.1.2.2.2 bouyer smaller than the target buffer. Integers that are converted to buffers will 5312 1.1.1.2.2.2 bouyer not cause buffer truncation, only zero extension (both as per the ACPI 5313 1.1.1.2.2.2 bouyer spec.) The problem was introduced when code was added to truncate the 5314 1.1.1.2.2.2 bouyer buffer, but this should not be performed in all cases, only the string case. 5315 1.1.1.2.2.2 bouyer 5316 1.1.1.2.2.2 bouyer Fixed a problem with the Buffer and Package operators where the interpreter 5317 1.1.1.2.2.2 bouyer would get confused if two such operators were used as operands to an ASL 5318 1.1.1.2.2.2 bouyer operator (such as LLess(Buffer(1){0},Buffer(1){1}). The internal result 5319 1.1.1.2.2.2 bouyer stack was not being popped after the execution of these operators, resulting 5320 1.1.1.2.2.2 bouyer in an AE_NO_RETURN_VALUE exception. 5321 1.1.1.2.2.2 bouyer 5322 1.1.1.2.2.2 bouyer Fixed a problem with constructs of the form Store(Index(...),...). The 5323 1.1.1.2.2.2 bouyer reference object returned from Index was inadvertently resolved to an actual 5324 1.1.1.2.2.2 bouyer value. This problem was introduced in version 20050114 when the behavior of 5325 1.1.1.2.2.2 bouyer Store() was modified to restrict the object types that can be used as the 5326 1.1.1.2.2.2 bouyer source operand (to match the ACPI specification.) 5327 1.1.1.2.2.2 bouyer 5328 1.1.1.2.2.2 bouyer Reduced excessive stack use within the AcpiGetObjectInfo procedure. 5329 1.1.1.2.2.2 bouyer 5330 1.1.1.2.2.2 bouyer Added a fix to aclinux.h to allow generation of AcpiExec on Linux. 5331 1.1.1.2.2.2 bouyer 5332 1.1.1.2.2.2 bouyer Updated the AcpiSrc utility to add the FADT_DESCRIPTOR_REV2_MINUS struct. 5333 1.1.1.2.2.2 bouyer 5334 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5335 1.1.1.2.2.2 bouyer shown below.

The debug version of the code includes the 5338 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5339 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5340 1.1.1.2.2.2 bouyer the compiler options used during generation. 5341 1.1.1.2.2.2 bouyer 5342 1.1.1.2.2.2 bouyer Previous Release: 5343 1.1.1.2.2.2 bouyer Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 5344 1.1.1.2.2.2 bouyer Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 5345 1.1.1.2.2.2 bouyer Current Release: 5346 1.1.1.2.2.2 bouyer Non-Debug Version: 78.2K Code, 11.5K Data, 89.7K Total 5347 1.1.1.2.2.2 bouyer Debug Version: 164.9K Code, 69.2K Data, 234.1K Total 5348 1.1.1.2.2.2 bouyer 5349 1.1.1.2.2.2 bouyer 5350 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 5351 1.1.1.2.2.2 bouyer 5352 1.1.1.2.2.2 bouyer Fixed a code generation problem in the constant folding optimization code 5353 1.1.1.2.2.2 bouyer where incorrect code was generated if a constant was reduced to a buffer 5354 1.1.1.2.2.2 bouyer object (i.e., a reduced type 5 opcode.) 5355 1.1.1.2.2.2 bouyer 5356 1.1.1.2.2.2 bouyer Fixed a typechecking problem for the ToBuffer operator. Caused by an 5357 1.1.1.2.2.2 bouyer incorrect return type in the internal opcode information table. 5358 1.1.1.2.2.2 bouyer 5359 1.1.1.2.2.2 bouyer ---------------------------------------- 5360 1.1.1.2.2.2 bouyer 25 January 2005. Summary of changes for version 20050125: 5361 1.1.1.2.2.2 bouyer 5362 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5363 1.1.1.2.2.2 bouyer 5364 1.1.1.2.2.2 bouyer Fixed a recently introduced problem with the Global Lock where the 5365 1.1.1.2.2.2 bouyer underlying semaphore was not created. This problem was introduced in 5366 1.1.1.2.2.2 bouyer version 20050114, and caused an AE_AML_NO_OPERAND exception during an 5367 1.1.1.2.2.2 bouyer Acquire() operation on _GL. 5368 1.1.1.2.2.2 bouyer 5369 1.1.1.2.2.2 bouyer The local object cache is now optional, and is disabled by default. Both 5370 1.1.1.2.2.2 bouyer AcpiExec and the iASL compiler enable the cache because they run in user 5371 1.1.1.2.2.2 bouyer mode and this enhances their performance. #define ACPI_ENABLE_OBJECT_CACHE 5372 1.1.1.2.2.2 bouyer to enable the local cache. 5373 1.1.1.2.2.2 bouyer 5374 1.1.1.2.2.2 bouyer Fixed an issue in the internal function AcpiUtEvaluateObject concerning the 5375 1.1.1.2.2.2 bouyer optional "implicit return" support where an error was returned if no return 5376 1.1.1.2.2.2 bouyer object was expected, but one was implicitly returned. AE_OK is now returned 5377 1.1.1.2.2.2 bouyer in this case and the implicitly returned object is deleted. 5378 1.1.1.2.2.2 bouyer AcpiUtEvaluateObject is only occasionally used, and only to execute reserved 5379 1.1.1.2.2.2 bouyer methods such as _STA and _INI where the return type is known up front. 5380 1.1.1.2.2.2 bouyer 5381 1.1.1.2.2.2 bouyer Fixed a few issues with the internal convert-to-integer code. It now returns 5382 1.1.1.2.2.2 bouyer an error if an attempt is made to convert a null string, a string of only 5383 1.1.1.2.2.2 bouyer blanks/tabs, or a zero-length buffer. This affects both implicit conversion 5384 1.1.1.2.2.2 bouyer and explicit conversion via the ToInteger() operator. 5385 1.1.1.2.2.2 bouyer 5386 1.1.1.2.2.2 bouyer The internal debug code in AcpiUtAcquireMutex has been commented out. It is 5387 1.1.1.2.2.2 bouyer not needed for normal operation and should increase the performance of the 5388 1.1.1.2.2.2 bouyer entire subsystem. The code remains in case it is needed for debug purposes 5389 1.1.1.2.2.2 bouyer again. 5390 1.1.1.2.2.2 bouyer 5391 1.1.1.2.2.2 bouyer The AcpiExec source and makefile are included in the Unix/Linux package for 5392 1.1.1.2.2.2 bouyer the first time. 5393 1.1.1.2.2.2 bouyer 5394 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5395 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 5396 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5397 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 5398 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5399 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5400 1.1.1.2.2.2 bouyer the compiler options used during generation. 5401 1.1.1.2.2.2 bouyer 5402 1.1.1.2.2.2 bouyer Previous Release: 5403 1.1.1.2.2.2 bouyer Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total 5404 1.1.1.2.2.2 bouyer Debug Version: 165.4K Code, 69.4K Data, 234.8K Total 5405 1.1.1.2.2.2 bouyer Current Release: 5406 1.1.1.2.2.2 bouyer Non-Debug Version: 78.1K Code, 11.5K Data, 89.6K Total 5407 1.1.1.2.2.2 bouyer Debug Version: 164.8K Code, 69.2K Data, 234.0K Total 5408 1.1.1.2.2.2 bouyer 5409 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 5410 1.1.1.2.2.2 bouyer 5411 1.1.1.2.2.2 bouyer Switch/Case support: A warning is now issued if the type of the Switch value 5412 1.1.1.2.2.2 bouyer cannot be determined at compile time. For example, Switch(Arg0) will 5413 1.1.1.2.2.2 bouyer generate the warning, and the type is assumed to be an integer. As per the 5414 1.1.1.2.2.2 bouyer ACPI spec, use a construct such as Switch(ToInteger(Arg0)) to eliminate the 5415 1.1.1.2.2.2 bouyer warning. 5416 1.1.1.2.2.2 bouyer 5417 1.1.1.2.2.2 bouyer Switch/Case support: Implemented support for buffer and string objects as 5418 1.1.1.2.2.2 bouyer the switch value. This is an ACPI 3.0 feature, now that LEqual supports 5419 1.1.1.2.2.2 bouyer buffers and strings. 5420 1.1.1.2.2.2 bouyer 5421 1.1.1.2.2.2 bouyer Switch/Case support: The emitted code for the LEqual() comparisons now uses 5422 1.1.1.2.2.2 bouyer the switch value as the first operand, not the second. The case value is now 5423 1.1.1.2.2.2 bouyer the second operand, and this allows the case value to be implicitly 5424 1.1.1.2.2.2 bouyer converted to the type of the switch value, not the other way around. 5425 1.1.1.2.2.2 bouyer 5426 1.1.1.2.2.2 bouyer Switch/Case support: Temporary variables are now emitted immediately within 5427 1.1.1.2.2.2 bouyer the control method, not at the global level. This means that there are now 5428 1.1.1.2.2.2 bouyer 36 temps available per-method, not 36 temps per-module as was the case with 5429 1.1.1.2.2.2 bouyer the earlier implementation (_T_0 through _T_9 and _T_A through _T_Z.) 5430 1.1.1.2.2.2 bouyer 5431 1.1.1.2.2.2 bouyer ---------------------------------------- 5432 1.1.1.2.2.2 bouyer 14 January 2005. Summary of changes for version 20050114: 5433 1.1.1.2.2.2 bouyer 5434 1.1.1.2.2.2 bouyer Added 2005 copyright to all module headers. This affects every module in 5435 1.1.1.2.2.2 bouyer the core subsystem, iASL compiler, and the utilities. 5436 1.1.1.2.2.2 bouyer 5437 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5438 1.1.1.2.2.2 bouyer 5439 1.1.1.2.2.2 bouyer Fixed an issue with the String-to-Buffer conversion code where the string 5440 1.1.1.2.2.2 bouyer null terminator was not included in the buffer after conversion, but there 5441 1.1.1.2.2.2 bouyer is existing ASL that assumes the string null terminator is included. This is 5442 1.1.1.2.2.2 bouyer the root of the ACPI_AML_BUFFER_LIMIT regression. This problem was 5443 1.1.1.2.2.2 bouyer introduced in the previous version when the code was updated to correctly 5444 1.1.1.2.2.2 bouyer set the converted buffer size as per the ACPI specification. The ACPI spec 5445 1.1.1.2.2.2 bouyer is ambiguous and will be updated to specify that the null terminator must be 5446 1.1.1.2.2.2 bouyer included in the converted buffer. This also affects the ToBuffer() ASL 5447 1.1.1.2.2.2 bouyer operator. 5448 1.1.1.2.2.2 bouyer 5449 1.1.1.2.2.2 bouyer Fixed a problem with the Mid() ASL/AML operator where it did not work 5450 1.1.1.2.2.2 bouyer correctly on Buffer objects. Newly created sub-buffers were not being marked 5451 1.1.1.2.2.2 bouyer as initialized. 5452 1.1.1.2.2.2 bouyer 5453 1.1.1.2.2.2 bouyer 5454 1.1.1.2.2.2 bouyer Fixed a problem in AcpiTbFindTable where incorrect string compares were 5455 1.1.1.2.2.2 bouyer performed on the OemId and OemTableId table header fields. These fields are 5456 1.1.1.2.2.2 bouyer not null terminated, so strncmp is now used instead of strcmp. 5457 1.1.1.2.2.2 bouyer 5458 1.1.1.2.2.2 bouyer Implemented a restriction on the Store() ASL/AML operator to align the 5459 1.1.1.2.2.2 bouyer behavior with the ACPI specification. Previously, any object could be used 5460 1.1.1.2.2.2 bouyer as the source operand. Now, the only objects that may be used are Integers, 5461 1.1.1.2.2.2 bouyer Buffers, Strings, Packages, Object References, and DDB Handles. If 5462 1.1.1.2.2.2 bouyer necessary, the original behavior can be restored by enabling the 5463 1.1.1.2.2.2 bouyer EnableInterpreterSlack flag. 5464 1.1.1.2.2.2 bouyer 5465 1.1.1.2.2.2 bouyer Enhanced the optional "implicit return" support to allow an implicit return 5466 1.1.1.2.2.2 bouyer value from methods that are invoked externally via the AcpiEvaluateObject 5467 1.1.1.2.2.2 bouyer interface. This enables implicit returns from the _STA and _INI methods, 5468 1.1.1.2.2.2 bouyer for example. 5469 1.1.1.2.2.2 bouyer 5470 1.1.1.2.2.2 bouyer Changed the Revision() ASL/AML operator to return the current version of the 5471 1.1.1.2.2.2 bouyer AML interpreter, in the YYYYMMDD format. Previously, it incorrectly returned 5472 1.1.1.2.2.2 bouyer the supported ACPI version (This is the function of the _REV method). 5473 1.1.1.2.2.2 bouyer 5474 1.1.1.2.2.2 bouyer Updated the _REV predefined method to return the currently supported version 5475 1.1.1.2.2.2 bouyer of ACPI, now 3. 5476 1.1.1.2.2.2 bouyer 5477 1.1.1.2.2.2 bouyer Implemented batch mode option for the AcpiExec utility (-b). 5478 1.1.1.2.2.2 bouyer 5479 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5480 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 5481 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5482 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 5483 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5484 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5485 1.1.1.2.2.2 bouyer the compiler options used during generation. 5486 1.1.1.2.2.2 bouyer 5487 1.1.1.2.2.2 bouyer Previous Release: 5488 1.1.1.2.2.2 bouyer Non-Debug Version: 78.3K Code, 11.5K Data, 89.8K Total 5489 1.1.1.2.2.2 bouyer Debug Version: 165.3K Code, 69.4K Data, 234.7K Total 5490 1.1.1.2.2.2 bouyer Current Release: 5491 1.1.1.2.2.2 bouyer Non-Debug Version: 78.4K Code, 11.5K Data, 89.9K Total 5492 1.1.1.2.2.2 bouyer Debug Version: 165.4K Code, 69.4K Data, 234.8K Total 5493 1.1.1.2.2.2 bouyer 5494 1.1.1.2.2.2 bouyer ---------------------------------------- 5495 1.1.1.2.2.2 bouyer 10 December 2004.

Summary of changes for version 20041119: 5606 1.1.1.2.2.2 bouyer 5607 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5608 1.1.1.2.2.2 bouyer 5609 1.1.1.2.2.2 bouyer Fixed a problem in the internal ConvertToInteger routine where new integers 5610 1.1.1.2.2.2 bouyer were not truncated to 32 bits for 32-bit ACPI tables. This routine converts 5611 1.1.1.2.2.2 bouyer buffers and strings to integers. 5612 1.1.1.2.2.2 bouyer 5613 1.1.1.2.2.2 bouyer Implemented support to store a value to an Index() on a String object. This 5614 1.1.1.2.2.2 bouyer is an ACPI 2.0 feature that had not yet been implemented. 5615 1.1.1.2.2.2 bouyer 5616 1.1.1.2.2.2 bouyer Implemented new behavior for storing objects to individual package elements 5617 1.1.1.2.2.2 bouyer (via the Index() operator). The previous behavior was to invoke the implicit 5618 1.1.1.2.2.2 bouyer conversion rules if an object was already present at the index. The new 5619 1.1.1.2.2.2 bouyer behavior is to simply delete any existing object and directly store the new 5620 1.1.1.2.2.2 bouyer object. Although the ACPI specification seems unclear on this subject, other 5621 1.1.1.2.2.2 bouyer ACPI implementations behave in this manner. (This is the root of the 5622 1.1.1.2.2.2 bouyer AE_BAD_HEX_CONSTANT issue.) 5623 1.1.1.2.2.2 bouyer 5624 1.1.1.2.2.2 bouyer Modified the RSDP memory scan mechanism to support the extended checksum for 5625 1.1.1.2.2.2 bouyer ACPI 2.0 (and above) RSDPs. Note that the search continues until a valid 5626 1.1.1.2.2.2 bouyer RSDP signature is found with a valid checksum. 5627 1.1.1.2.2.2 bouyer 5628 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5629 1.1.1.2.2.2 bouyer shown below.

Summary of changes for version 20041105: 5650 1.1.1.2.2.2 bouyer 5651 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5652 1.1.1.2.2.2 bouyer 5653 1.1.1.2.2.2 bouyer Implemented support for FADT revision 2. This was an interim table (between 5654 1.1.1.2.2.2 bouyer ACPI 1.0 and ACPI 2.0) that adds support for the FADT reset register. 5655 1.1.1.2.2.2 bouyer 5656 1.1.1.2.2.2 bouyer Implemented optional support to allow uninitialized LocalX and ArgX 5657 1.1.1.2.2.2 bouyer variables in a control method. The variables are initialized to an Integer 5658 1.1.1.2.2.2 bouyer object with a value of zero. This support is enabled by setting the 5659 1.1.1.2.2.2 bouyer AcpiGbl_EnableInterpreterSlack flag to TRUE. 5660 1.1.1.2.2.2 bouyer 5661 1.1.1.2.2.2 bouyer Implemented support for Integer objects for the SizeOf operator. Either 4 5662 1.1.1.2.2.2 bouyer or 8 is returned, depending on the current integer size (32-bit or 64-bit, 5663 1.1.1.2.2.2 bouyer depending on the parent table revision). 5664 1.1.1.2.2.2 bouyer 5665 1.1.1.2.2.2 bouyer Fixed a problem in the implementation of the SizeOf and ObjectType operators 5666 1.1.1.2.2.2 bouyer where the operand was resolved to a value too early, causing incorrect 5667 1.1.1.2.2.2 bouyer return values for some objects. 5668 1.1.1.2.2.2 bouyer 5669 1.1.1.2.2.2 bouyer Fixed some possible memory leaks during exceptional conditions. 5670 1.1.1.2.2.2 bouyer 5671 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5672 1.1.1.2.2.2 bouyer shown below.

All EISAID strings must be of the form "UUUNNNN" Where 5768 1.1.1.2.2.2 bouyer U is an uppercase letter and N is a hex digit. 5769 1.1.1.2.2.2 bouyer 5770 1.1.1.2.2.2 bouyer 5771 1.1.1.2.2.2 bouyer ---------------------------------------- 5772 1.1.1.2.2.2 bouyer 06 October 2004. Summary of changes for version 20041006: 5773 1.1.1.2.2.2 bouyer 5774 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5775 1.1.1.2.2.2 bouyer 5776 1.1.1.2.2.2 bouyer Implemented support for the ACPI 3.0 Timer operator. This ASL function 5777 1.1.1.2.2.2 bouyer implements a 64-bit timer with 100 nanosecond granularity. 5778 1.1.1.2.2.2 bouyer 5779 1.1.1.2.2.2 bouyer Defined a new OSL interface, AcpiOsGetTimer. This interface is used to 5780 1.1.1.2.2.2 bouyer implement the ACPI 3.0 Timer operator. This allows the host OS to implement 5781 1.1.1.2.2.2 bouyer the timer with the best clock available. Also, it keeps the core subsystem 5782 1.1.1.2.2.2 bouyer out of the clock handling business, since the host OS (usually) performs 5783 1.1.1.2.2.2 bouyer this function. 5784 1.1.1.2.2.2 bouyer 5785 1.1.1.2.2.2 bouyer Fixed an alignment issue on 64-bit platforms. The HwLowLevelRead(Write) 5786 1.1.1.2.2.2 bouyer functions use a 64-bit address which is part of the packed ACPI Generic 5787 1.1.1.2.2.2 bouyer Address Structure. Since the structure is non-aligned, the alignment macros 5788 1.1.1.2.2.2 bouyer are now used to extract the address to a local variable before use. 5789 1.1.1.2.2.2 bouyer 5790 1.1.1.2.2.2 bouyer Fixed a problem where the ToInteger operator assumed all input strings were 5791 1.1.1.2.2.2 bouyer hexadecimal. The operator now handles both decimal strings and hex strings 5792 1.1.1.2.2.2 bouyer (prefixed with "0x"). 5793 1.1.1.2.2.2 bouyer 5794 1.1.1.2.2.2 bouyer Fixed a problem where the string length in the string object created as a 5795 1.1.1.2.2.2 bouyer result of the internal ConvertToString procedure could be incorrect. This 5796 1.1.1.2.2.2 bouyer potentially affected all implicit conversions and also the ToDecimalString 5797 1.1.1.2.2.2 bouyer and ToHexString operators. 5798 1.1.1.2.2.2 bouyer 5799 1.1.1.2.2.2 bouyer Fixed two problems in the ToString operator. If the length parameter was 5800 1.1.1.2.2.2 bouyer zero, an incorrect string object was created and the value of the input 5801 1.1.1.2.2.2 bouyer length parameter was inadvertently changed from zero to Ones. 5802 1.1.1.2.2.2 bouyer 5803 1.1.1.2.2.2 bouyer Fixed a problem where the optional ResourceSource string in the ExtendedIRQ 5804 1.1.1.2.2.2 bouyer resource macro was ignored. 5805 1.1.1.2.2.2 bouyer 5806 1.1.1.2.2.2 bouyer Simplified the interfaces to the internal division functions, reducing code 5807 1.1.1.2.2.2 bouyer size and complexity. 5808 1.1.1.2.2.2 bouyer 5809 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5810 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 5811 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 5812 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 5813 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 5814 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 5815 1.1.1.2.2.2 bouyer the compiler options used during generation. 5816 1.1.1.2.2.2 bouyer 5817 1.1.1.2.2.2 bouyer Previous Release: 5818 1.1.1.2.2.2 bouyer Non-Debug Version: 77.9K Code, 11.4K Data, 89.3K Total 5819 1.1.1.2.2.2 bouyer Debug Version: 164.5K Code, 68.3K Data, 232.8K Total 5820 1.1.1.2.2.2 bouyer Current Release: 5821 1.1.1.2.2.2 bouyer Non-Debug Version: 77.8K Code, 11.5K Data, 89.3K Total 5822 1.1.1.2.2.2 bouyer Debug Version: 164.6K Code, 68.5K Data, 233.1K Total 5823 1.1.1.2.2.2 bouyer 5824 1.1.1.2.2.2 bouyer 5825 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 5826 1.1.1.2.2.2 bouyer 5827 1.1.1.2.2.2 bouyer Implemented support for the ACPI 3.0 Timer operator. 5828 1.1.1.2.2.2 bouyer 5829 1.1.1.2.2.2 bouyer Fixed a problem where the Default() operator was inadvertently ignored in a 5830 1.1.1.2.2.2 bouyer Switch/Case block. This was a problem in the translation of the Switch 5831 1.1.1.2.2.2 bouyer statement to If...Else pairs. 5832 1.1.1.2.2.2 bouyer 5833 1.1.1.2.2.2 bouyer Added support to allow a standalone Return operator, with no parentheses (or 5834 1.1.1.2.2.2 bouyer operands). 5835 1.1.1.2.2.2 bouyer 5836 1.1.1.2.2.2 bouyer Fixed a problem with code generation for the ElseIf operator where the 5837 1.1.1.2.2.2 bouyer translated Else...If parse tree was improperly constructed leading to the 5838 1.1.1.2.2.2 bouyer loss of some code. 5839 1.1.1.2.2.2 bouyer 5840 1.1.1.2.2.2 bouyer ---------------------------------------- 5841 1.1.1.2.2.2 bouyer 22 September 2004. Summary of changes for version 20040922: 5842 1.1.1.2.2.2 bouyer 5843 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5844 1.1.1.2.2.2 bouyer 5845 1.1.1.2.2.2 bouyer Fixed a problem with the implementation of the LNot() operator where "Ones" 5846 1.1.1.2.2.2 bouyer was not returned for the TRUE case. Changed the code to return Ones instead 5847 1.1.1.2.2.2 bouyer of (!Arg) which was usually 1. This change affects iASL constant folding for 5848 1.1.1.2.2.2 bouyer this operator also. 5849 1.1.1.2.2.2 bouyer 5850 1.1.1.2.2.2 bouyer Fixed a problem in AcpiUtInitializeBuffer where an existing buffer was not 5851 1.1.1.2.2.2 bouyer initialized properly -- Now zero the entire buffer in this case where the 5852 1.1.1.2.2.2 bouyer buffer already exists. 5853 1.1.1.2.2.2 bouyer 5854 1.1.1.2.2.2 bouyer Changed the interface to AcpiOsSleep from (UINT32 Seconds, UINT32 5855 1.1.1.2.2.2 bouyer Milliseconds) to simply (ACPI_INTEGER Milliseconds). This simplifies all 5856 1.1.1.2.2.2 bouyer related code considerably. This will require changes/updates to all OS 5857 1.1.1.2.2.2 bouyer interface layers (OSLs.) 5858 1.1.1.2.2.2 bouyer 5859 1.1.1.2.2.2 bouyer Implemented a new external interface, AcpiInstallExceptionHandler, to allow 5860 1.1.1.2.2.2 bouyer a system exception handler to be installed. This handler is invoked upon any 5861 1.1.1.2.2.2 bouyer run-time exception that occurs during control method execution. 5862 1.1.1.2.2.2 bouyer 5863 1.1.1.2.2.2 bouyer Added support for the DSDT in AcpiTbFindTable. This allows the 5864 1.1.1.2.2.2 bouyer DataTableRegion() operator to access the local copy of the DSDT. 5865 1.1.1.2.2.2 bouyer 5866 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5867 1.1.1.2.2.2 bouyer shown below.

LNot was 5885 1.1.1.2.2.2 bouyer returning 1 in the TRUE case, not Ones as per the ACPI specification. This 5886 1.1.1.2.2.2 bouyer could result in the generation of an incorrect folded/reduced constant. 5887 1.1.1.2.2.2 bouyer 5888 1.1.1.2.2.2 bouyer End-Of-File is now allowed within a "//"-style comment. A parse error no 5889 1.1.1.2.2.2 bouyer longer occurs if such a comment is at the very end of the input ASL source 5890 1.1.1.2.2.2 bouyer file. 5891 1.1.1.2.2.2 bouyer 5892 1.1.1.2.2.2 bouyer Implemented the "-r" option to override the Revision in the table header. 5893 1.1.1.2.2.2 bouyer The initial use of this option will be to simplify the evaluation of the AML 5894 1.1.1.2.2.2 bouyer interpreter by allowing a single ASL source module to be compiled for either 5895 1.1.1.2.2.2 bouyer 32-bit or 64-bit integers. 5896 1.1.1.2.2.2 bouyer 5897 1.1.1.2.2.2 bouyer 5898 1.1.1.2.2.2 bouyer ---------------------------------------- 5899 1.1.1.2.2.2 bouyer 27 August 2004. Summary of changes for version 20040827: 5900 1.1.1.2.2.2 bouyer 5901 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5902 1.1.1.2.2.2 bouyer 5903 1.1.1.2.2.2 bouyer - Implemented support for implicit object conversion in the non-numeric 5904 1.1.1.2.2.2 bouyer logical operators (LEqual, LGreater, LGreaterEqual, LLess, LLessEqual, and 5905 1.1.1.2.2.2 bouyer LNotEqual.) Any combination of Integers/Strings/Buffers may now be used; 5906 1.1.1.2.2.2 bouyer the second operand is implicitly converted on the fly to match the type of 5907 1.1.1.2.2.2 bouyer the first operand. For example: 5908 1.1.1.2.2.2 bouyer 5909 1.1.1.2.2.2 bouyer LEqual (Source1, Source2) 5910 1.1.1.2.2.2 bouyer 5911 1.1.1.2.2.2 bouyer Source1 and Source2 must each evaluate to an integer, a string, or a buffer. 5912 1.1.1.2.2.2 bouyer The data type of Source1 dictates the required type of Source2. Source2 is 5913 1.1.1.2.2.2 bouyer implicitly converted if necessary to match the type of Source1. 5914 1.1.1.2.2.2 bouyer 5915 1.1.1.2.2.2 bouyer - Updated and corrected the behavior of the string conversion support. The 5916 1.1.1.2.2.2 bouyer rules concerning conversion of buffers to strings (according to the ACPI 5917 1.1.1.2.2.2 bouyer specification) are as follows: 5918 1.1.1.2.2.2 bouyer 5919 1.1.1.2.2.2 bouyer ToDecimalString - explicit byte-wise conversion of buffer to string of 5920 1.1.1.2.2.2 bouyer decimal values (0-255) separated by commas. ToHexString - explicit byte-wise 5921 1.1.1.2.2.2 bouyer conversion of buffer to string of hex values (0-FF) separated by commas. 5922 1.1.1.2.2.2 bouyer ToString - explicit byte-wise conversion of buffer to string. Byte-by-byte 5923 1.1.1.2.2.2 bouyer copy with no transform except NULL terminated. Any other implicit buffer-to- 5924 1.1.1.2.2.2 bouyer string conversion - byte-wise conversion of buffer to string of hex values 5925 1.1.1.2.2.2 bouyer (0-FF) separated by spaces. 5926 1.1.1.2.2.2 bouyer 5927 1.1.1.2.2.2 bouyer - Fixed typo in definition of AcpiGbl_EnableInterpreterSlack. 5928 1.1.1.2.2.2 bouyer 5929 1.1.1.2.2.2 bouyer - Fixed a problem in AcpiNsGetPathnameLength where the returned length was 5930 1.1.1.2.2.2 bouyer one byte too short in the case of a node in the root scope. This could 5931 1.1.1.2.2.2 bouyer cause a fault during debug output. 5932 1.1.1.2.2.2 bouyer 5933 1.1.1.2.2.2 bouyer - Code and Data Size: Current and previous core subsystem library sizes are 5934 1.1.1.2.2.2 bouyer shown below.

Summary of changes for version 20040816: 5956 1.1.1.2.2.2 bouyer 5957 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 5958 1.1.1.2.2.2 bouyer 5959 1.1.1.2.2.2 bouyer Designed and implemented support within the AML interpreter for the so- 5960 1.1.1.2.2.2 bouyer called "implicit return". This support returns the result of the last ASL 5961 1.1.1.2.2.2 bouyer operation within a control method, in the absence of an explicit Return() 5962 1.1.1.2.2.2 bouyer operator. A few machines depend on this behavior, even though it is not 5963 1.1.1.2.2.2 bouyer explicitly supported by the ASL language. It is optional support that can 5964 1.1.1.2.2.2 bouyer be enabled at runtime via the AcpiGbl_EnableInterpreterSlack flag. 5965 1.1.1.2.2.2 bouyer 5966 1.1.1.2.2.2 bouyer Removed support for the PCI_Config address space from the internal low level 5967 1.1.1.2.2.2 bouyer hardware interfaces (AcpiHwLowLevelRead and AcpiHwLowLevelWrite). This 5968 1.1.1.2.2.2 bouyer support was not used internally, and would not work correctly anyway because 5969 1.1.1.2.2.2 bouyer the PCI bus number and segment number were not supported. There are 5970 1.1.1.2.2.2 bouyer separate interfaces for PCI configuration space access because of the unique 5971 1.1.1.2.2.2 bouyer interface. 5972 1.1.1.2.2.2 bouyer 5973 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 5974 1.1.1.2.2.2 bouyer shown below.

Behavior is similar 6008 1.1.1.2.2.2 bouyer to C library "strcmp". 6009 1.1.1.2.2.2 bouyer 6010 1.1.1.2.2.2 bouyer Completed a major reduction in CPU stack use for the AcpiGetFirmwareTable 6011 1.1.1.2.2.2 bouyer external function. In the 32-bit non-debug case, the stack use has been 6012 1.1.1.2.2.2 bouyer reduced from 168 bytes to 32 bytes. 6013 1.1.1.2.2.2 bouyer 6014 1.1.1.2.2.2 bouyer Deployed a new run-time configuration flag, AcpiGbl_EnableInterpreterSlack, 6015 1.1.1.2.2.2 bouyer whose purpose is to allow the AML interpreter to forgive certain bad AML 6016 1.1.1.2.2.2 bouyer constructs. Default setting is FALSE. 6017 1.1.1.2.2.2 bouyer 6018 1.1.1.2.2.2 bouyer Implemented the first use of AcpiGbl_EnableInterpreterSlack in the Field IO 6019 1.1.1.2.2.2 bouyer support code. If enabled, it allows field access to go beyond the end of a 6020 1.1.1.2.2.2 bouyer region definition if the field is within the region length rounded up to the 6021 1.1.1.2.2.2 bouyer next access width boundary (a common coding error.) 6022 1.1.1.2.2.2 bouyer 6023 1.1.1.2.2.2 bouyer Renamed OSD_HANDLER to ACPI_OSD_HANDLER, and OSD_EXECUTION_CALLBACK to 6024 1.1.1.2.2.2 bouyer ACPI_OSD_EXEC_CALLBACK for consistency with other ACPI symbols. Also, these 6025 1.1.1.2.2.2 bouyer symbols are lowercased by the latest version of the AcpiSrc tool. 6026 1.1.1.2.2.2 bouyer 6027 1.1.1.2.2.2 bouyer The prototypes for the PCI interfaces in acpiosxf.h have been updated to 6028 1.1.1.2.2.2 bouyer rename "Register" to simply "Reg" to prevent certain compilers from 6029 1.1.1.2.2.2 bouyer complaining. 6030 1.1.1.2.2.2 bouyer 6031 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 6032 1.1.1.2.2.2 bouyer shown below.

Note 6197 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 6198 1.1.1.2.2.2 bouyer the compiler options used during generation. 6199 1.1.1.2.2.2 bouyer 6200 1.1.1.2.2.2 bouyer Previous Release: 6201 1.1.1.2.2.2 bouyer Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 6202 1.1.1.2.2.2 bouyer Debug Version: 162.9K Code, 67.0K Data, 229.9K Total 6203 1.1.1.2.2.2 bouyer Current Release: 6204 1.1.1.2.2.2 bouyer Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 6205 1.1.1.2.2.2 bouyer Debug Version: 163.2K Code, 67.2K Data, 230.4K Total 6206 1.1.1.2.2.2 bouyer 6207 1.1.1.2.2.2 bouyer ---------------------------------------- 6208 1.1.1.2.2.2 bouyer 27 April 2004. Summary of changes for version 20040427: 6209 1.1.1.2.2.2 bouyer 6210 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6211 1.1.1.2.2.2 bouyer 6212 1.1.1.2.2.2 bouyer Completed a major overhaul of the GPE handling within ACPI CA. There are 6213 1.1.1.2.2.2 bouyer now three types of GPEs: wake-only, runtime-only, and combination wake/run. 6214 1.1.1.2.2.2 bouyer The only GPEs allowed to be combination wake/run are for button-style 6215 1.1.1.2.2.2 bouyer devices such as a control-method power button, control-method sleep button, 6216 1.1.1.2.2.2 bouyer or a notebook lid switch. GPEs that have an _Lxx or _Exx method and are not 6217 1.1.1.2.2.2 bouyer referenced by any _PRW methods are marked for "runtime" and hardware 6218 1.1.1.2.2.2 bouyer enabled. Any GPE that is referenced by a _PRW method is marked for "wake" 6219 1.1.1.2.2.2 bouyer (and disabled at runtime). However, at sleep time, only those GPEs that 6220 1.1.1.2.2.2 bouyer have been specifically enabled for wake via the AcpiEnableGpe interface will 6221 1.1.1.2.2.2 bouyer actually be hardware enabled. 6222 1.1.1.2.2.2 bouyer 6223 1.1.1.2.2.2 bouyer A new external interface has been added, AcpiSetGpeType(), that is meant to 6224 1.1.1.2.2.2 bouyer be used by device drivers to force a GPE to a particular type. It will be 6225 1.1.1.2.2.2 bouyer especially useful for the drivers for the button devices mentioned above. 6226 1.1.1.2.2.2 bouyer 6227 1.1.1.2.2.2 bouyer Completed restructuring of the ACPI CA initialization sequence so that 6228 1.1.1.2.2.2 bouyer default operation region handlers are installed before GPEs are initialized 6229 1.1.1.2.2.2 bouyer and the _PRW methods are executed. This will prevent errors when the _PRW 6230 1.1.1.2.2.2 bouyer methods attempt to access system memory or I/O space. 6231 1.1.1.2.2.2 bouyer 6232 1.1.1.2.2.2 bouyer GPE enable/disable no longer reads the GPE enable register. We now keep the 6233 1.1.1.2.2.2 bouyer enable info for runtime and wake separate and in the GPE_EVENT_INFO. We 6234 1.1.1.2.2.2 bouyer thus no longer depend on the hardware to maintain these bits. 6235 1.1.1.2.2.2 bouyer 6236 1.1.1.2.2.2 bouyer Always clear the wake status and fixed/GPE status bits before sleep, even 6237 1.1.1.2.2.2 bouyer for state S5. 6238 1.1.1.2.2.2 bouyer 6239 1.1.1.2.2.2 bouyer Improved the AML debugger output for displaying the GPE blocks and their 6240 1.1.1.2.2.2 bouyer current status. 6241 1.1.1.2.2.2 bouyer 6242 1.1.1.2.2.2 bouyer Added new strings for the _OSI method, of the form "Windows 2001 SPx" where 6243 1.1.1.2.2.2 bouyer x = 0,1,2,3,4. 6244 1.1.1.2.2.2 bouyer 6245 1.1.1.2.2.2 bouyer Fixed a problem where the physical address was incorrectly calculated when 6246 1.1.1.2.2.2 bouyer the Load() operator was used to directly load from an Operation Region (vs. 6247 1.1.1.2.2.2 bouyer loading from a Field object.) Also added check for minimum table length for 6248 1.1.1.2.2.2 bouyer this case. 6249 1.1.1.2.2.2 bouyer 6250 1.1.1.2.2.2 bouyer Fix for multiple mutex acquisition. Restore original thread SyncLevel on 6251 1.1.1.2.2.2 bouyer mutex release. 6252 1.1.1.2.2.2 bouyer 6253 1.1.1.2.2.2 bouyer Added ACPI_VALID_SXDS flag to the AcpiGetObjectInfo interface for 6254 1.1.1.2.2.2 bouyer consistency with the other fields returned. 6255 1.1.1.2.2.2 bouyer 6256 1.1.1.2.2.2 bouyer Shrunk the ACPI_GPE_EVENT_INFO structure by 40%. There is one such 6257 1.1.1.2.2.2 bouyer structure for each GPE in the system, so the size of this structure is 6258 1.1.1.2.2.2 bouyer important. 6259 1.1.1.2.2.2 bouyer 6260 1.1.1.2.2.2 bouyer CPU stack requirement reduction: Cleaned up the method execution and object 6261 1.1.1.2.2.2 bouyer evaluation paths so that now a parameter structure is passed, instead of 6262 1.1.1.2.2.2 bouyer copying the various method parameters over and over again. 6263 1.1.1.2.2.2 bouyer 6264 1.1.1.2.2.2 bouyer In evregion.c: Correctly exit and reenter the interpreter region if and 6265 1.1.1.2.2.2 bouyer only if dispatching an operation region request to a user-installed handler. 6266 1.1.1.2.2.2 bouyer Do not exit/reenter when dispatching to a default handler (e.g., default 6267 1.1.1.2.2.2 bouyer system memory or I/O handlers) 6268 1.1.1.2.2.2 bouyer 6269 1.1.1.2.2.2 bouyer 6270 1.1.1.2.2.2 bouyer Notes for updating drivers for the new GPE support. The following changes 6271 1.1.1.2.2.2 bouyer must be made to ACPI-related device drivers that are attached to one or more 6272 1.1.1.2.2.2 bouyer GPEs: (This information will be added to the ACPI CA Programmer Reference.) 6273 1.1.1.2.2.2 bouyer 6274 1.1.1.2.2.2 bouyer 1) AcpiInstallGpeHandler no longer automatically enables the GPE, you must 6275 1.1.1.2.2.2 bouyer explicitly call AcpiEnableGpe. 6276 1.1.1.2.2.2 bouyer 2) There is a new interface called AcpiSetGpeType. This should be called 6277 1.1.1.2.2.2 bouyer before enabling the GPE. Also, this interface will automatically disable 6278 1.1.1.2.2.2 bouyer the GPE if it is currently enabled. 6279 1.1.1.2.2.2 bouyer 3) AcpiEnableGpe no longer supports a GPE type flag. 6280 1.1.1.2.2.2 bouyer 6281 1.1.1.2.2.2 bouyer Specific drivers that must be changed: 6282 1.1.1.2.2.2 bouyer 1) EC driver: 6283 1.1.1.2.2.2 bouyer AcpiInstallGpeHandler (NULL, GpeNum, ACPI_GPE_EDGE_TRIGGERED, 6284 1.1.1.2.2.2 bouyer AeGpeHandler, NULL); 6285 1.1.1.2.2.2 bouyer AcpiSetGpeType (NULL, GpeNum, ACPI_GPE_TYPE_RUNTIME); 6286 1.1.1.2.2.2 bouyer AcpiEnableGpe (NULL, GpeNum, ACPI_NOT_ISR); 6287 1.1.1.2.2.2 bouyer 6288 1.1.1.2.2.2 bouyer 2) Button Drivers (Power, Lid, Sleep): 6289 1.1.1.2.2.2 bouyer Run _PRW method under parent device 6290 1.1.1.2.2.2 bouyer If _PRW exists: /* This is a control-method button */ 6291 1.1.1.2.2.2 bouyer Extract GPE number and possibly GpeDevice 6292 1.1.1.2.2.2 bouyer AcpiSetGpeType (GpeDevice, GpeNum, ACPI_GPE_TYPE_WAKE_RUN); 6293 1.1.1.2.2.2 bouyer AcpiEnableGpe (GpeDevice, GpeNum, ACPI_NOT_ISR); 6294 1.1.1.2.2.2 bouyer 6295 1.1.1.2.2.2 bouyer For all other devices that have _PRWs, we automatically set the GPE type to 6296 1.1.1.2.2.2 bouyer ACPI_GPE_TYPE_WAKE, but the GPE is NOT automatically (wake) enabled. This 6297 1.1.1.2.2.2 bouyer must be done on a selective basis, usually requiring some kind of user app 6298 1.1.1.2.2.2 bouyer to allow the user to pick the wake devices. 6299 1.1.1.2.2.2 bouyer 6300 1.1.1.2.2.2 bouyer 6301 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 6302 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 6303 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6304 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 6305 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 6306 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 6307 1.1.1.2.2.2 bouyer the compiler options used during generation. 6308 1.1.1.2.2.2 bouyer 6309 1.1.1.2.2.2 bouyer Previous Release: 6310 1.1.1.2.2.2 bouyer Non-Debug Version: 77.0K Code, 11.4K Data, 88.4K Total 6311 1.1.1.2.2.2 bouyer Debug Version: 161.0K Code, 66.3K Data, 227.3K Total 6312 1.1.1.2.2.2 bouyer Current Release: 6313 1.1.1.2.2.2 bouyer 6314 1.1.1.2.2.2 bouyer Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total 6315 1.1.1.2.2.2 bouyer Debug Version: 162.9K Code, 67.0K Data, 229.9K Total 6316 1.1.1.2.2.2 bouyer 6317 1.1.1.2.2.2 bouyer 6318 1.1.1.2.2.2 bouyer 6319 1.1.1.2.2.2 bouyer ---------------------------------------- 6320 1.1.1.2.2.2 bouyer 02 April 2004. Summary of changes for version 20040402: 6321 1.1.1.2.2.2 bouyer 6322 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6323 1.1.1.2.2.2 bouyer 6324 1.1.1.2.2.2 bouyer Fixed an interpreter problem where an indirect store through an ArgX 6325 1.1.1.2.2.2 bouyer parameter was incorrectly applying the "implicit conversion rules" during 6326 1.1.1.2.2.2 bouyer the store. From the ACPI specification: "If the target is a method local or 6327 1.1.1.2.2.2 bouyer argument (LocalX or ArgX), no conversion is performed and the result is 6328 1.1.1.2.2.2 bouyer stored directly to the target". The new behavior is to disable implicit 6329 1.1.1.2.2.2 bouyer conversion during ALL stores to an ArgX. 6330 1.1.1.2.2.2 bouyer 6331 1.1.1.2.2.2 bouyer Changed the behavior of the _PRW method scan to ignore any and all errors 6332 1.1.1.2.2.2 bouyer returned by a given _PRW. This prevents the scan from aborting from the 6333 1.1.1.2.2.2 bouyer failure of any single _PRW. 6334 1.1.1.2.2.2 bouyer 6335 1.1.1.2.2.2 bouyer Moved the runtime configuration parameters from the global init procedure to 6336 1.1.1.2.2.2 bouyer static variables in acglobal.h. This will allow the host to override the 6337 1.1.1.2.2.2 bouyer default values easily. 6338 1.1.1.2.2.2 bouyer 6339 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 6340 1.1.1.2.2.2 bouyer shown below.

However, External() statements are not 6358 1.1.1.2.2.2 bouyer generated automatically for unresolved symbols at this time. This is a 6359 1.1.1.2.2.2 bouyer planned feature for future implementation. 6360 1.1.1.2.2.2 bouyer 6361 1.1.1.2.2.2 bouyer Fixed a scoping problem in the disassembler that occurs when the type of the 6362 1.1.1.2.2.2 bouyer target of a Scope() operator is overridden. This problem caused an 6363 1.1.1.2.2.2 bouyer incorrectly nested internal namespace to be constructed. 6364 1.1.1.2.2.2 bouyer 6365 1.1.1.2.2.2 bouyer Any warnings or errors that are emitted during disassembly are now commented 6366 1.1.1.2.2.2 bouyer out automatically so that the resulting file can be recompiled without any 6367 1.1.1.2.2.2 bouyer hand editing. 6368 1.1.1.2.2.2 bouyer 6369 1.1.1.2.2.2 bouyer ---------------------------------------- 6370 1.1.1.2.2.2 bouyer 26 March 2004. Summary of changes for version 20040326: 6371 1.1.1.2.2.2 bouyer 6372 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6373 1.1.1.2.2.2 bouyer 6374 1.1.1.2.2.2 bouyer Implemented support for "wake" GPEs via interaction between GPEs and the 6375 1.1.1.2.2.2 bouyer _PRW methods. Every GPE that is pointed to by one or more _PRWs is 6376 1.1.1.2.2.2 bouyer identified as a WAKE GPE and by default will no longer be enabled at 6377 1.1.1.2.2.2 bouyer runtime. Previously, we were blindly enabling all GPEs with a corresponding 6378 1.1.1.2.2.2 bouyer _Lxx or _Exx method - but most of these turn out to be WAKE GPEs anyway. We 6379 1.1.1.2.2.2 bouyer believe this has been the cause of thousands of "spurious" GPEs on some 6380 1.1.1.2.2.2 bouyer systems. 6381 1.1.1.2.2.2 bouyer 6382 1.1.1.2.2.2 bouyer This new GPE behavior is can be reverted to the original behavior (enable 6383 1.1.1.2.2.2 bouyer ALL GPEs at runtime) via a runtime flag. 6384 1.1.1.2.2.2 bouyer 6385 1.1.1.2.2.2 bouyer Fixed a problem where aliased control methods could not access objects 6386 1.1.1.2.2.2 bouyer properly. The proper scope within the namespace was not initialized 6387 1.1.1.2.2.2 bouyer (transferred to the target of the aliased method) before executing the 6388 1.1.1.2.2.2 bouyer target method. 6389 1.1.1.2.2.2 bouyer 6390 1.1.1.2.2.2 bouyer Fixed a potential race condition on internal object deletion on the return 6391 1.1.1.2.2.2 bouyer object in AcpiEvaluateObject. 6392 1.1.1.2.2.2 bouyer 6393 1.1.1.2.2.2 bouyer Integrated a fix for resource descriptors where both _MEM and _MTP were 6394 1.1.1.2.2.2 bouyer being extracted instead of just _MEM. (i.e. bitmask was incorrectly too 6395 1.1.1.2.2.2 bouyer wide, 0x0F instead of 0x03.) 6396 1.1.1.2.2.2 bouyer 6397 1.1.1.2.2.2 bouyer Added a special case for ACPI_ROOT_OBJECT in AcpiUtGetNodeName, preventing a 6398 1.1.1.2.2.2 bouyer fault in some cases. 6399 1.1.1.2.2.2 bouyer 6400 1.1.1.2.2.2 bouyer Updated Notify() values for debug statements in evmisc.c 6401 1.1.1.2.2.2 bouyer 6402 1.1.1.2.2.2 bouyer Return proper status from AcpiUtMutexInitialize, not just simply AE_OK. 6403 1.1.1.2.2.2 bouyer 6404 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 6405 1.1.1.2.2.2 bouyer shown below. These are the code and data sizes for the acpica.lib produced 6406 1.1.1.2.2.2 bouyer by the Microsoft Visual C++ 6.0 compiler, and these values do not include 6407 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code includes the 6408 1.1.1.2.2.2 bouyer debug output trace mechanism and has a much larger code and data size. Note 6409 1.1.1.2.2.2 bouyer that these values will vary depending on the efficiency of the compiler and 6410 1.1.1.2.2.2 bouyer the compiler options used during generation. 6411 1.1.1.2.2.2 bouyer 6412 1.1.1.2.2.2 bouyer Previous Release: 6413 1.1.1.2.2.2 bouyer 6414 1.1.1.2.2.2 bouyer Non-Debug Version: 76.5K Code, 11.3K Data, 87.8K Total 6415 1.1.1.2.2.2 bouyer Debug Version: 160.3K Code, 66.0K Data, 226.3K Total 6416 1.1.1.2.2.2 bouyer Current Release: 6417 1.1.1.2.2.2 bouyer Non-Debug Version: 76.9K Code, 11.4K Data, 88.3K Total 6418 1.1.1.2.2.2 bouyer Debug Version: 160.8K Code, 66.1K Data, 226.9K Total 6419 1.1.1.2.2.2 bouyer 6420 1.1.1.2.2.2 bouyer ---------------------------------------- 6421 1.1.1.2.2.2 bouyer 11 March 2004. Summary of changes for version 20040311: 6422 1.1.1.2.2.2 bouyer 6423 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6424 1.1.1.2.2.2 bouyer 6425 1.1.1.2.2.2 bouyer Fixed a problem where errors occurring during the parse phase of control 6426 1.1.1.2.2.2 bouyer method execution did not abort cleanly. For example, objects created and 6427 1.1.1.2.2.2 bouyer installed in the namespace were not deleted. This caused all subsequent 6428 1.1.1.2.2.2 bouyer invocations of the method to return the AE_ALREADY_EXISTS exception. 6429 1.1.1.2.2.2 bouyer 6430 1.1.1.2.2.2 bouyer Implemented a mechanism to force a control method to "Serialized" execution 6431 1.1.1.2.2.2 bouyer if the method attempts to create namespace objects. (The root of the 6432 1.1.1.2.2.2 bouyer AE_ALREADY_EXISTS problem.) 6433 1.1.1.2.2.2 bouyer 6434 1.1.1.2.2.2 bouyer Implemented support for the predefined _OSI "internal" control method. 6435 1.1.1.2.2.2 bouyer Initial supported strings are "Linux", "Windows 2000", "Windows 2001", and 6436 1.1.1.2.2.2 bouyer "Windows 2001.1", and can be easily upgraded for new strings as necessary. 6437 1.1.1.2.2.2 bouyer This feature will allow "other" operating systems to execute the fully 6438 1.1.1.2.2.2 bouyer tested, "Windows" code path through the ASL code 6439 1.1.1.2.2.2 bouyer 6440 1.1.1.2.2.2 bouyer Global Lock Support: Now allows multiple acquires and releases with any 6441 1.1.1.2.2.2 bouyer internal thread. Removed concept of "owning thread" for this special mutex. 6442 1.1.1.2.2.2 bouyer 6443 1.1.1.2.2.2 bouyer Fixed two functions that were inappropriately declaring large objects on the 6444 1.1.1.2.2.2 bouyer CPU stack: PsParseLoop, NsEvaluateRelative. Reduces the stack usage during 6445 1.1.1.2.2.2 bouyer method execution considerably. 6446 1.1.1.2.2.2 bouyer 6447 1.1.1.2.2.2 bouyer Fixed a problem in the ACPI 2.0 FACS descriptor (actbl2.h) where the 6448 1.1.1.2.2.2 bouyer S4Bios_f field was incorrectly defined as UINT32 instead of UINT32_BIT. 6449 1.1.1.2.2.2 bouyer 6450 1.1.1.2.2.2 bouyer Fixed a problem where AcpiEvGpeDetect would fault if there were no GPEs 6451 1.1.1.2.2.2 bouyer defined on the machine. 6452 1.1.1.2.2.2 bouyer 6453 1.1.1.2.2.2 bouyer Implemented two runtime options: One to force all control method execution 6454 1.1.1.2.2.2 bouyer to "Serialized" to mimic Windows behavior, another to disable _OSI support 6455 1.1.1.2.2.2 bouyer if it causes problems on a given machine. 6456 1.1.1.2.2.2 bouyer 6457 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library sizes are 6458 1.1.1.2.2.2 bouyer shown below.

Summary of changes for version 20031029: 6619 1.1.1.2.2.2 bouyer 6620 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6621 1.1.1.2.2.2 bouyer 6622 1.1.1.2.2.2 bouyer 6623 1.1.1.2.2.2 bouyer Fixed a problem where a level-triggered GPE with an associated 6624 1.1.1.2.2.2 bouyer _Lxx control method was incorrectly cleared twice. 6625 1.1.1.2.2.2 bouyer 6626 1.1.1.2.2.2 bouyer Fixed a problem with the Field support code where an access can 6627 1.1.1.2.2.2 bouyer occur beyond the end-of-region if the field is non-aligned but 6628 1.1.1.2.2.2 bouyer extends to the very end of the parent region (resulted in an 6629 1.1.1.2.2.2 bouyer AE_AML_REGION_LIMIT exception.) 6630 1.1.1.2.2.2 bouyer 6631 1.1.1.2.2.2 bouyer Fixed a problem with ACPI Fixed Events where an RT Clock handler 6632 1.1.1.2.2.2 bouyer would not get invoked on an RTC event. The RTC event bitmasks for 6633 1.1.1.2.2.2 bouyer the PM1 registers were not being initialized properly. 6634 1.1.1.2.2.2 bouyer 6635 1.1.1.2.2.2 bouyer Implemented support for executing _STA and _INI methods for 6636 1.1.1.2.2.2 bouyer Processor objects. Although this is currently not part of the 6637 1.1.1.2.2.2 bouyer ACPI specification, there is existing ASL code that depends on the 6638 1.1.1.2.2.2 bouyer init-time execution of these methods. 6639 1.1.1.2.2.2 bouyer 6640 1.1.1.2.2.2 bouyer Implemented and deployed a GetDescriptorName function to decode 6641 1.1.1.2.2.2 bouyer the various types of internal descriptors. Guards against null 6642 1.1.1.2.2.2 bouyer descriptors during debug output also. 6643 1.1.1.2.2.2 bouyer 6644 1.1.1.2.2.2 bouyer Implemented and deployed a GetNodeName function to extract the 4- 6645 1.1.1.2.2.2 bouyer character namespace node name. This function simplifies the debug 6646 1.1.1.2.2.2 bouyer and error output, as well as guarding against null pointers during 6647 1.1.1.2.2.2 bouyer output. 6648 1.1.1.2.2.2 bouyer 6649 1.1.1.2.2.2 bouyer Implemented and deployed the ACPI_FORMAT_UINT64 helper macro to 6650 1.1.1.2.2.2 bouyer simplify the debug and error output of 64-bit integers. This 6651 1.1.1.2.2.2 bouyer macro replaces the HIDWORD and LODWORD macros for dumping these 6652 1.1.1.2.2.2 bouyer integers. 6653 1.1.1.2.2.2 bouyer 6654 1.1.1.2.2.2 bouyer Updated the implementation of the Stall() operator to only call 6655 1.1.1.2.2.2 bouyer AcpiOsStall(), and also return an error if the operand is larger 6656 1.1.1.2.2.2 bouyer than 255. This preserves the required behavior of not 6657 1.1.1.2.2.2 bouyer relinquishing the processor, as would happen if AcpiOsSleep() was 6658 1.1.1.2.2.2 bouyer called for "long stalls". 6659 1.1.1.2.2.2 bouyer 6660 1.1.1.2.2.2 bouyer Constructs of the form "Store(LocalX,LocalX)" where LocalX is not 6661 1.1.1.2.2.2 bouyer initialized are now treated as NOOPs. 6662 1.1.1.2.2.2 bouyer 6663 1.1.1.2.2.2 bouyer Cleaned up a handful of warnings during 64-bit generation. 6664 1.1.1.2.2.2 bouyer 6665 1.1.1.2.2.2 bouyer Fixed a reported error where and incorrect GPE number was passed 6666 1.1.1.2.2.2 bouyer to the GPE dispatch handler. This value is only used for error 6667 1.1.1.2.2.2 bouyer output, however. Used this opportunity to clean up and streamline 6668 1.1.1.2.2.2 bouyer the GPE dispatch code. 6669 1.1.1.2.2.2 bouyer 6670 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library 6671 1.1.1.2.2.2 bouyer sizes are shown below. These are the code and data sizes for the 6672 1.1.1.2.2.2 bouyer acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and 6673 1.1.1.2.2.2 bouyer these values do not include any ACPI driver or OSPM code. The 6674 1.1.1.2.2.2 bouyer 6675 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace 6676 1.1.1.2.2.2 bouyer mechanism and has a much larger code and data size. Note that 6677 1.1.1.2.2.2 bouyer these values will vary depending on the efficiency of the compiler 6678 1.1.1.2.2.2 bouyer and the compiler options used during generation. 6679 1.1.1.2.2.2 bouyer 6680 1.1.1.2.2.2 bouyer Previous Release (20031002): 6681 1.1.1.2.2.2 bouyer Non-Debug Version: 74.1K Code, 9.7K Data, 83.8K Total 6682 1.1.1.2.2.2 bouyer Debug Version: 157.9K Code, 64.8K Data, 222.7K Total 6683 1.1.1.2.2.2 bouyer Current Release: 6684 1.1.1.2.2.2 bouyer Non-Debug Version: 74.4K Code, 10.1K Data, 84.5K Total 6685 1.1.1.2.2.2 bouyer Debug Version: 158.3K Code, 65.0K Data, 223.3K Total 6686 1.1.1.2.2.2 bouyer 6687 1.1.1.2.2.2 bouyer 6688 1.1.1.2.2.2 bouyer 2) iASL Compiler/Disassembler: 6689 1.1.1.2.2.2 bouyer 6690 1.1.1.2.2.2 bouyer Updated the iASL compiler to return an error if the operand to the 6691 1.1.1.2.2.2 bouyer Stall() operator is larger than 255. 6692 1.1.1.2.2.2 bouyer 6693 1.1.1.2.2.2 bouyer 6694 1.1.1.2.2.2 bouyer ---------------------------------------- 6695 1.1.1.2.2.2 bouyer 02 October 2003.

If the name string 6765 1.1.1.2.2.2 bouyer specified for the name of the new object placed the object in a 6766 1.1.1.2.2.2 bouyer scope other than the current scope, the initialization/execution 6767 1.1.1.2.2.2 bouyer of the opcode failed. The solution to this problem was to 6768 1.1.1.2.2.2 bouyer implement a mechanism where the late execution of such opcodes 6769 1.1.1.2.2.2 bouyer does not attempt to lookup/create the name a second time in an 6770 1.1.1.2.2.2 bouyer incorrect scope. This fixes the "region size computed 6771 1.1.1.2.2.2 bouyer incorrectly" problem. 6772 1.1.1.2.2.2 bouyer 6773 1.1.1.2.2.2 bouyer Fixed a call to AcpiHwRegisterWrite in hwregs.c that was causing a 6774 1.1.1.2.2.2 bouyer Global Lock AE_BAD_PARAMETER error. 6775 1.1.1.2.2.2 bouyer 6776 1.1.1.2.2.2 bouyer Fixed several 64-bit issues with prototypes, casting and data 6777 1.1.1.2.2.2 bouyer types. 6778 1.1.1.2.2.2 bouyer 6779 1.1.1.2.2.2 bouyer Removed duplicate prototype from acdisasm.h 6780 1.1.1.2.2.2 bouyer 6781 1.1.1.2.2.2 bouyer Fixed an issue involving EC Operation Region Detach (Shaohua Li) 6782 1.1.1.2.2.2 bouyer 6783 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library 6784 1.1.1.2.2.2 bouyer sizes are shown below.

Summary of changes for version 20030522: 6862 1.1.1.2.2.2 bouyer 6863 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 6864 1.1.1.2.2.2 bouyer 6865 1.1.1.2.2.2 bouyer Found and fixed a reported problem where an AE_NOT_FOUND error 6866 1.1.1.2.2.2 bouyer occurred occasionally during _BST evaluation. This turned out to 6867 1.1.1.2.2.2 bouyer be an Owner ID allocation issue where a called method did not get 6868 1.1.1.2.2.2 bouyer a new ID assigned to it. Eventually, (after 64k calls), the Owner 6869 1.1.1.2.2.2 bouyer ID UINT16 would wraparound so that the ID would be the same as the 6870 1.1.1.2.2.2 bouyer caller's and the called method would delete the caller's 6871 1.1.1.2.2.2 bouyer namespace. 6872 1.1.1.2.2.2 bouyer 6873 1.1.1.2.2.2 bouyer Implemented extended error reporting for control methods that are 6874 1.1.1.2.2.2 bouyer aborted due to a run-time exception. Output includes the exact 6875 1.1.1.2.2.2 bouyer AML instruction that caused the method abort, a dump of the method 6876 1.1.1.2.2.2 bouyer locals and arguments at the time of the abort, and a trace of all 6877 1.1.1.2.2.2 bouyer nested control method calls. 6878 1.1.1.2.2.2 bouyer 6879 1.1.1.2.2.2 bouyer Modified the interpreter to allow the creation of buffers of zero 6880 1.1.1.2.2.2 bouyer length from the AML code. Implemented new code to ensure that no 6881 1.1.1.2.2.2 bouyer attempt is made to actually allocate a memory buffer (of length 6882 1.1.1.2.2.2 bouyer zero) - instead, a simple buffer object with a NULL buffer pointer 6883 1.1.1.2.2.2 bouyer and length zero is created. A warning is no longer issued when 6884 1.1.1.2.2.2 bouyer the AML attempts to create a zero-length buffer. 6885 1.1.1.2.2.2 bouyer 6886 1.1.1.2.2.2 bouyer Implemented a workaround for the "leading asterisk issue" in 6887 1.1.1.2.2.2 bouyer _HIDs, _UIDs, and _CIDs in the AML interpreter. One leading 6888 1.1.1.2.2.2 bouyer asterisk is automatically removed if present in any HID, UID, or 6889 1.1.1.2.2.2 bouyer CID strings. The iASL compiler will still flag this asterisk as 6890 1.1.1.2.2.2 bouyer an error, however. 6891 1.1.1.2.2.2 bouyer 6892 1.1.1.2.2.2 bouyer Implemented full support for _CID methods that return a package of 6893 1.1.1.2.2.2 bouyer multiple CIDs (Compatible IDs). The AcpiGetObjectInfo() interface 6894 1.1.1.2.2.2 bouyer now additionally returns a device _CID list if present. This 6895 1.1.1.2.2.2 bouyer required a change to the external interface in order to pass an 6896 1.1.1.2.2.2 bouyer ACPI_BUFFER object as a parameter since the _CID list is of 6897 1.1.1.2.2.2 bouyer variable length. 6898 1.1.1.2.2.2 bouyer 6899 1.1.1.2.2.2 bouyer Fixed a problem with the new AE_SAME_HANDLER exception where 6900 1.1.1.2.2.2 bouyer handler initialization code did not know about this exception. 6901 1.1.1.2.2.2 bouyer 6902 1.1.1.2.2.2 bouyer Code and Data Size: Current and previous core subsystem library 6903 1.1.1.2.2.2 bouyer sizes are shown below.

The 6906 1.1.1.2.2.2 bouyer debug version of the code includes the debug output trace 6907 1.1.1.2.2.2 bouyer mechanism and has a much larger code and data size. Note that 6908 1.1.1.2.2.2 bouyer these values will vary depending on the efficiency of the compiler 6909 1.1.1.2.2.2 bouyer and the compiler options used during generation. 6910 1.1.1.2.2.2 bouyer 6911 1.1.1.2.2.2 bouyer Previous Release (20030509): 6912 1.1.1.2.2.2 bouyer Non-Debug Version: 73.4K Code, 9.7K Data, 83.1K Total 6913 1.1.1.2.2.2 bouyer Debug Version: 156.1K Code, 63.9K Data, 220.0K Total 6914 1.1.1.2.2.2 bouyer Current Release: 6915 1.1.1.2.2.2 bouyer Non-Debug Version: 73.7K Code, 9.7K Data, 83.4K Total 6916 1.1.1.2.2.2 bouyer Debug Version: 156.9K Code, 64.2K Data, 221.1K Total 6917 1.1.1.2.2.2 bouyer 6918 1.1.1.2.2.2 bouyer 6919 1.1.1.2.2.2 bouyer 2) Linux: 6920 1.1.1.2.2.2 bouyer 6921 1.1.1.2.2.2 bouyer Fixed a bug in which we would reinitialize the ACPI interrupt 6922 1.1.1.2.2.2 bouyer after it was already working, thus disabling all ACPI and the IRQs 6923 1.1.1.2.2.2 bouyer for any other device sharing the interrupt.

This is because 6955 1.1.1.2.2.2 bouyer the installation of space handlers can cause _REG methods to be 6956 1.1.1.2.2.2 bouyer run. Previously, the _REG methods could potentially be run before 6957 1.1.1.2.2.2 bouyer ACPI mode was enabled. 6958 1.1.1.2.2.2 bouyer 6959 1.1.1.2.2.2 bouyer Fixed some memory leak issues related to address space handler and 6960 1.1.1.2.2.2 bouyer notify handler installation. There were some problems with the 6961 1.1.1.2.2.2 bouyer reference count mechanism caused by the fact that the handler 6962 1.1.1.2.2.2 bouyer objects are shared across several namespace objects. 6963 1.1.1.2.2.2 bouyer 6964 1.1.1.2.2.2 bouyer Fixed a reported problem where reference counts within the 6965 1.1.1.2.2.2 bouyer namespace were not properly updated when named objects created by 6966 1.1.1.2.2.2 bouyer method execution were deleted. 6967 1.1.1.2.2.2 bouyer 6968 1.1.1.2.2.2 bouyer Fixed a reported problem where multiple SSDTs caused a deletion 6969 1.1.1.2.2.2 bouyer issue during subsystem termination. Restructured the table data 6970 1.1.1.2.2.2 bouyer structures to simplify the linked lists and the related code. 6971 1.1.1.2.2.2 bouyer 6972 1.1.1.2.2.2 bouyer Fixed a problem where the table ID associated with secondary 6973 1.1.1.2.2.2 bouyer tables (SSDTs) was not being propagated into the namespace objects 6974 1.1.1.2.2.2 bouyer created by those tables. This would only present a problem for 6975 1.1.1.2.2.2 bouyer tables that are unloaded at run-time, however. 6976 1.1.1.2.2.2 bouyer 6977 1.1.1.2.2.2 bouyer Updated AcpiOsReadable and AcpiOsWritable to use the ACPI_SIZE 6978 1.1.1.2.2.2 bouyer type as the length parameter (instead of UINT32). 6979 1.1.1.2.2.2 bouyer 6980 1.1.1.2.2.2 bouyer Solved a long-standing problem where an ALREADY_EXISTS error 6981 1.1.1.2.2.2 bouyer appears on various systems. This problem could happen when there 6982 1.1.1.2.2.2 bouyer are multiple PCI_Config operation regions under a single PCI root 6983 1.1.1.2.2.2 bouyer bus. This doesn't happen very frequently, but there are some 6984 1.1.1.2.2.2 bouyer systems that do this in the ASL. 6985 1.1.1.2.2.2 bouyer 6986 1.1.1.2.2.2 bouyer Fixed a reported problem where the internal DeleteNode function 6987 1.1.1.2.2.2 bouyer was incorrectly handling the case where a namespace node was the 6988 1.1.1.2.2.2 bouyer first in the parent's child list, and had additional peers (not 6989 1.1.1.2.2.2 bouyer the only child, but first in the list of children.) 6990 1.1.1.2.2.2 bouyer 6991 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 6992 1.1.1.2.2.2 bouyer below.

One new file has been 7103 1.1.1.2.2.2 bouyer added, evgpeblk.c 7104 1.1.1.2.2.2 bouyer 7105 1.1.1.2.2.2 bouyer The FADT fields GPE0_BLK_LEN and GPE1_BLK_LEN are now the only 7106 1.1.1.2.2.2 bouyer fields that are used to determine the GPE block lengths. The 7107 1.1.1.2.2.2 bouyer REGISTER_BIT_WIDTH field of the X_GPEx_BLK extended address 7108 1.1.1.2.2.2 bouyer structures are ignored. This is per the ACPI specification but it 7109 1.1.1.2.2.2 bouyer isn't very clear. The full 256 Block 0/1 GPEs are now supported 7110 1.1.1.2.2.2 bouyer (the use of REGISTER_BIT_WIDTH limited the number of GPEs to 128). 7111 1.1.1.2.2.2 bouyer 7112 1.1.1.2.2.2 bouyer In the SCI interrupt handler, removed the read of the PM1_CONTROL 7113 1.1.1.2.2.2 bouyer register to look at the SCI_EN bit. On some machines, this read 7114 1.1.1.2.2.2 bouyer causes an SMI event and greatly slows down SCI events. (This may 7115 1.1.1.2.2.2 bouyer in fact be the cause of slow battery status response on some 7116 1.1.1.2.2.2 bouyer systems.) 7117 1.1.1.2.2.2 bouyer 7118 1.1.1.2.2.2 bouyer Fixed a problem where a store of a NULL string to a package object 7119 1.1.1.2.2.2 bouyer could cause the premature deletion of the object. This was seen 7120 1.1.1.2.2.2 bouyer during execution of the battery _BIF method on some systems, 7121 1.1.1.2.2.2 bouyer resulting in no battery data being returned. 7122 1.1.1.2.2.2 bouyer 7123 1.1.1.2.2.2 bouyer Added AcpiWalkResources interface to simplify parsing of resource 7124 1.1.1.2.2.2 bouyer lists. 7125 1.1.1.2.2.2 bouyer 7126 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7127 1.1.1.2.2.2 bouyer below.

The current ACPI specification states that the contents 7244 1.1.1.2.2.2 bouyer of the buffer are "converted to a string of two-character 7245 1.1.1.2.2.2 bouyer hexadecimal numbers, each separated by a space". Unfortunately, 7246 1.1.1.2.2.2 bouyer this definition is not backwards compatible with existing ACPI 1.0 7247 1.1.1.2.2.2 bouyer implementations (although the behavior was not defined in the ACPI 7248 1.1.1.2.2.2 bouyer 1.0 specification). The new behavior simply copies data from the 7249 1.1.1.2.2.2 bouyer buffer to the string until a null character is found or the end of 7250 1.1.1.2.2.2 bouyer the buffer is reached. The new String object is always null 7251 1.1.1.2.2.2 bouyer terminated. This problem was seen during the generation of _BIF 7252 1.1.1.2.2.2 bouyer battery data where incorrect strings were returned for battery 7253 1.1.1.2.2.2 bouyer type, etc. This will also require an errata to the ACPI 7254 1.1.1.2.2.2 bouyer specification. 7255 1.1.1.2.2.2 bouyer 7256 1.1.1.2.2.2 bouyer Renamed all instances of NATIVE_UINT and NATIVE_INT to 7257 1.1.1.2.2.2 bouyer ACPI_NATIVE_UINT and ACPI_NATIVE_INT, respectively. 7258 1.1.1.2.2.2 bouyer 7259 1.1.1.2.2.2 bouyer Copyright in all module headers (both Linux and non-Linux) has be 7260 1.1.1.2.2.2 bouyer updated to 2003. 7261 1.1.1.2.2.2 bouyer 7262 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7263 1.1.1.2.2.2 bouyer below.

Summary of changes for version 20021205. 7363 1.1.1.2.2.2 bouyer 7364 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 7365 1.1.1.2.2.2 bouyer 7366 1.1.1.2.2.2 bouyer Fixed a problem where a store to a String or Buffer object could 7367 1.1.1.2.2.2 bouyer cause corruption of the DSDT if the object type being stored was 7368 1.1.1.2.2.2 bouyer the same as the target object type and the length of the object 7369 1.1.1.2.2.2 bouyer being stored was equal to or smaller than the original (existing) 7370 1.1.1.2.2.2 bouyer target object. This was seen to cause corruption of battery _BIF 7371 1.1.1.2.2.2 bouyer buffers if the _BIF method modified the buffer on the fly. 7372 1.1.1.2.2.2 bouyer 7373 1.1.1.2.2.2 bouyer Fixed a problem where an internal error was generated if a control 7374 1.1.1.2.2.2 bouyer method invocation was used in an OperationRegion, Buffer, or 7375 1.1.1.2.2.2 bouyer Package declaration. This was caused by the deferred parsing of 7376 1.1.1.2.2.2 bouyer the control method and thus the deferred creation of the internal 7377 1.1.1.2.2.2 bouyer method object. The solution to this problem was to create the 7378 1.1.1.2.2.2 bouyer internal method object at the moment the method is encountered in 7379 1.1.1.2.2.2 bouyer the first pass - so that subsequent references to the method will 7380 1.1.1.2.2.2 bouyer able to obtain the required parameter count and thus properly 7381 1.1.1.2.2.2 bouyer parse the method invocation. This problem presented itself as an 7382 1.1.1.2.2.2 bouyer AE_AML_INTERNAL during the pass 1 parse phase during table load. 7383 1.1.1.2.2.2 bouyer 7384 1.1.1.2.2.2 bouyer Fixed a problem where the internal String object copy routine did 7385 1.1.1.2.2.2 bouyer not always allocate sufficient memory for the target String object 7386 1.1.1.2.2.2 bouyer and caused memory corruption. This problem was seen to cause 7387 1.1.1.2.2.2 bouyer "Allocation already present in list!" errors as memory allocation 7388 1.1.1.2.2.2 bouyer became corrupted. 7389 1.1.1.2.2.2 bouyer 7390 1.1.1.2.2.2 bouyer Implemented a new function for the evaluation of namespace objects 7391 1.1.1.2.2.2 bouyer that allows the specification of the allowable return object 7392 1.1.1.2.2.2 bouyer types. This simplifies a lot of code that checks for a return 7393 1.1.1.2.2.2 bouyer object of one or more specific objects returned from the 7394 1.1.1.2.2.2 bouyer evaluation (such as _STA, etc.) This may become and external 7395 1.1.1.2.2.2 bouyer function if it would be useful to ACPI-related drivers. 7396 1.1.1.2.2.2 bouyer 7397 1.1.1.2.2.2 bouyer Completed another round of prefixing #defines with "ACPI_" for 7398 1.1.1.2.2.2 bouyer clarity. 7399 1.1.1.2.2.2 bouyer 7400 1.1.1.2.2.2 bouyer Completed additional code restructuring to allow more modular 7401 1.1.1.2.2.2 bouyer linking for iASL compiler and AcpiExec. Several files were split 7402 1.1.1.2.2.2 bouyer creating new files. New files: nsparse.c dsinit.c evgpe.c 7403 1.1.1.2.2.2 bouyer 7404 1.1.1.2.2.2 bouyer Implemented an abort mechanism to terminate an executing control 7405 1.1.1.2.2.2 bouyer method via the AML debugger. This feature is useful for debugging 7406 1.1.1.2.2.2 bouyer control methods that depend (wait) for specific hardware 7407 1.1.1.2.2.2 bouyer responses. 7408 1.1.1.2.2.2 bouyer 7409 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7410 1.1.1.2.2.2 bouyer below.

This caused 7448 1.1.1.2.2.2 bouyer all subsequent operations on the Local/Arg to also affect the 7449 1.1.1.2.2.2 bouyer original source of the store operation. 7450 1.1.1.2.2.2 bouyer 7451 1.1.1.2.2.2 bouyer Fixed a problem where a store operation to a Method Local or Arg 7452 1.1.1.2.2.2 bouyer was not completed properly if the Local/Arg contained a reference 7453 1.1.1.2.2.2 bouyer (from RefOf) to a named field. The general-purpose store-to- 7454 1.1.1.2.2.2 bouyer namespace-node code is now used so that this case is handled 7455 1.1.1.2.2.2 bouyer automatically. 7456 1.1.1.2.2.2 bouyer 7457 1.1.1.2.2.2 bouyer Fixed a problem where the internal object copy routine would cause 7458 1.1.1.2.2.2 bouyer a protection fault if the object being copied was a Package and 7459 1.1.1.2.2.2 bouyer contained either 1) a NULL package element or 2) a nested sub- 7460 1.1.1.2.2.2 bouyer package. 7461 1.1.1.2.2.2 bouyer 7462 1.1.1.2.2.2 bouyer Fixed a problem with the GPE initialization that resulted from an 7463 1.1.1.2.2.2 bouyer ambiguity in the ACPI specification. One section of the 7464 1.1.1.2.2.2 bouyer specification states that both the address and length of the GPE 7465 1.1.1.2.2.2 bouyer block must be zero if the block is not supported. Another section 7466 1.1.1.2.2.2 bouyer implies that only the address need be zero if the block is not 7467 1.1.1.2.2.2 bouyer supported. The code has been changed so that both the address and 7468 1.1.1.2.2.2 bouyer the length must be non-zero to indicate a valid GPE block (i.e., 7469 1.1.1.2.2.2 bouyer if either the address or the length is zero, the GPE block is 7470 1.1.1.2.2.2 bouyer invalid.) 7471 1.1.1.2.2.2 bouyer 7472 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7473 1.1.1.2.2.2 bouyer below.

Summary of changes for version 20021115. 7508 1.1.1.2.2.2 bouyer 7509 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 7510 1.1.1.2.2.2 bouyer 7511 1.1.1.2.2.2 bouyer Fixed a memory leak problem where an error during resolution of 7512 1.1.1.2.2.2 bouyer 7513 1.1.1.2.2.2 bouyer method arguments during a method invocation from another method 7514 1.1.1.2.2.2 bouyer failed to cleanup properly by deleting all successfully resolved 7515 1.1.1.2.2.2 bouyer argument objects. 7516 1.1.1.2.2.2 bouyer 7517 1.1.1.2.2.2 bouyer Fixed a problem where the target of the Index() operator was not 7518 1.1.1.2.2.2 bouyer correctly constructed if the source object was a package. This 7519 1.1.1.2.2.2 bouyer problem has not been detected because the use of a target operand 7520 1.1.1.2.2.2 bouyer with Index() is very rare. 7521 1.1.1.2.2.2 bouyer 7522 1.1.1.2.2.2 bouyer Fixed a problem with the Index() operator where an attempt was 7523 1.1.1.2.2.2 bouyer made to delete the operand objects twice. 7524 1.1.1.2.2.2 bouyer 7525 1.1.1.2.2.2 bouyer Fixed a problem where an attempt was made to delete an operand 7526 1.1.1.2.2.2 bouyer twice during execution of the CondRefOf() operator if the target 7527 1.1.1.2.2.2 bouyer did not exist. 7528 1.1.1.2.2.2 bouyer 7529 1.1.1.2.2.2 bouyer Implemented the first of perhaps several internal create object 7530 1.1.1.2.2.2 bouyer functions that create and initialize a specific object type. This 7531 1.1.1.2.2.2 bouyer consolidates duplicated code wherever the object is created, thus 7532 1.1.1.2.2.2 bouyer shrinking the size of the subsystem. 7533 1.1.1.2.2.2 bouyer 7534 1.1.1.2.2.2 bouyer Implemented improved debug/error messages for errors that occur 7535 1.1.1.2.2.2 bouyer during nested method invocations. All executing method pathnames 7536 1.1.1.2.2.2 bouyer are displayed (with the error) as the call stack is unwound - thus 7537 1.1.1.2.2.2 bouyer simplifying debug. 7538 1.1.1.2.2.2 bouyer 7539 1.1.1.2.2.2 bouyer Fixed a problem introduced in the 10/02 release that caused 7540 1.1.1.2.2.2 bouyer premature deletion of a buffer object if a buffer was used as an 7541 1.1.1.2.2.2 bouyer ASL operand where an integer operand is required (Thus causing an 7542 1.1.1.2.2.2 bouyer implicit object conversion from Buffer to Integer.) The change in 7543 1.1.1.2.2.2 bouyer the 10/02 release was attempting to fix a memory leak (albeit 7544 1.1.1.2.2.2 bouyer incorrectly.) 7545 1.1.1.2.2.2 bouyer 7546 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7547 1.1.1.2.2.2 bouyer below.

This paves the way for the 7601 1.1.1.2.2.2 bouyer development of SMBus drivers in each host operating system. 7602 1.1.1.2.2.2 bouyer 7603 1.1.1.2.2.2 bouyer Fixed a problem where the semaphore WAIT_FOREVER constant was 7604 1.1.1.2.2.2 bouyer defined as 32 bits, but must be 16 bits according to the ACPI 7605 1.1.1.2.2.2 bouyer specification. This had the side effect of causing ASL 7606 1.1.1.2.2.2 bouyer Mutex/Event timeouts even though the ASL code requested a wait 7607 1.1.1.2.2.2 bouyer forever. Changed all internal references to the ACPI timeout 7608 1.1.1.2.2.2 bouyer parameter to 16 bits to prevent future problems. Changed the name 7609 1.1.1.2.2.2 bouyer of WAIT_FOREVER to ACPI_WAIT_FOREVER. 7610 1.1.1.2.2.2 bouyer 7611 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7612 1.1.1.2.2.2 bouyer below.

This resulted in a "GPE 7648 1.1.1.2.2.2 bouyer overlap" error message. GPE0 is no longer required. 7649 1.1.1.2.2.2 bouyer 7650 1.1.1.2.2.2 bouyer Removed code added in the previous release that inserted nodes 7651 1.1.1.2.2.2 bouyer into the namespace in alphabetical order. This caused some side- 7652 1.1.1.2.2.2 bouyer effects on various machines. The root cause of the problem is 7653 1.1.1.2.2.2 bouyer still under investigation since in theory, the internal ordering 7654 1.1.1.2.2.2 bouyer of the namespace nodes should not matter. 7655 1.1.1.2.2.2 bouyer 7656 1.1.1.2.2.2 bouyer 7657 1.1.1.2.2.2 bouyer Enhanced error reporting for the case where a named object is not 7658 1.1.1.2.2.2 bouyer found during control method execution. The full ACPI namepath 7659 1.1.1.2.2.2 bouyer (name reference) of the object that was not found is displayed in 7660 1.1.1.2.2.2 bouyer this case. 7661 1.1.1.2.2.2 bouyer 7662 1.1.1.2.2.2 bouyer Note: as a result of the overhaul of the namespace object types in 7663 1.1.1.2.2.2 bouyer the previous release, the namespace nodes for the predefined 7664 1.1.1.2.2.2 bouyer scopes (_TZ, _PR, etc.) are now of the type ACPI_TYPE_LOCAL_SCOPE 7665 1.1.1.2.2.2 bouyer instead of ACPI_TYPE_ANY. This simplifies the namespace 7666 1.1.1.2.2.2 bouyer management code but may affect code that walks the namespace tree 7667 1.1.1.2.2.2 bouyer looking for specific object types. 7668 1.1.1.2.2.2 bouyer 7669 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7670 1.1.1.2.2.2 bouyer below.

This was related to the scope type change described above. 7691 1.1.1.2.2.2 bouyer 7692 1.1.1.2.2.2 bouyer 7693 1.1.1.2.2.2 bouyer 3) iASL Compiler/Disassembler 7694 1.1.1.2.2.2 bouyer 7695 1.1.1.2.2.2 bouyer Implemented the -g option to get all of the required ACPI tables 7696 1.1.1.2.2.2 bouyer from the registry and save them to files (Windows version of the 7697 1.1.1.2.2.2 bouyer compiler only.) The required tables are the FADT, FACS, and DSDT. 7698 1.1.1.2.2.2 bouyer 7699 1.1.1.2.2.2 bouyer Added ACPI table checksum validation during table disassembly in 7700 1.1.1.2.2.2 bouyer order to catch corrupted tables. 7701 1.1.1.2.2.2 bouyer 7702 1.1.1.2.2.2 bouyer 7703 1.1.1.2.2.2 bouyer ---------------------------------------- 7704 1.1.1.2.2.2 bouyer 22 October 2002. Summary of changes for version 20021022. 7705 1.1.1.2.2.2 bouyer 7706 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 7707 1.1.1.2.2.2 bouyer 7708 1.1.1.2.2.2 bouyer Implemented a restriction on the Scope operator that the target 7709 1.1.1.2.2.2 bouyer must already exist in the namespace at the time the operator is 7710 1.1.1.2.2.2 bouyer encountered (during table load or method execution). In other 7711 1.1.1.2.2.2 bouyer words, forward references are not allowed and Scope() cannot 7712 1.1.1.2.2.2 bouyer create a new object. This changes the previous behavior where the 7713 1.1.1.2.2.2 bouyer interpreter would create the name if not found. This new behavior 7714 1.1.1.2.2.2 bouyer correctly enables the search-to-root algorithm during namespace 7715 1.1.1.2.2.2 bouyer lookup of the target name. Because of this upsearch, this fixes 7716 1.1.1.2.2.2 bouyer the known Compaq _SB_.OKEC problem and makes both the AML 7717 1.1.1.2.2.2 bouyer interpreter and iASL compiler compatible with other ACPI 7718 1.1.1.2.2.2 bouyer implementations. 7719 1.1.1.2.2.2 bouyer 7720 1.1.1.2.2.2 bouyer Completed a major overhaul of the internal ACPI object types for 7721 1.1.1.2.2.2 bouyer the ACPI Namespace and the associated operand objects. Many of 7722 1.1.1.2.2.2 bouyer these types had become obsolete with the introduction of the two- 7723 1.1.1.2.2.2 bouyer pass namespace load. This cleanup simplifies the code and makes 7724 1.1.1.2.2.2 bouyer the entire namespace load mechanism much clearer and easier to 7725 1.1.1.2.2.2 bouyer understand. 7726 1.1.1.2.2.2 bouyer 7727 1.1.1.2.2.2 bouyer Improved debug output for tracking scope opening/closing to help 7728 1.1.1.2.2.2 bouyer diagnose scoping issues. The old scope name as well as the new 7729 1.1.1.2.2.2 bouyer scope name are displayed. Also improved error messages for 7730 1.1.1.2.2.2 bouyer problems with ASL Mutex objects and error messages for GPE 7731 1.1.1.2.2.2 bouyer problems. 7732 1.1.1.2.2.2 bouyer 7733 1.1.1.2.2.2 bouyer Cleaned up the namespace dump code, removed obsolete code. 7734 1.1.1.2.2.2 bouyer 7735 1.1.1.2.2.2 bouyer All string output (for all namespace/object dumps) now uses the 7736 1.1.1.2.2.2 bouyer common ACPI string output procedure which handles escapes properly 7737 1.1.1.2.2.2 bouyer and does not emit non-printable characters. 7738 1.1.1.2.2.2 bouyer 7739 1.1.1.2.2.2 bouyer Fixed some issues with constants in the 64-bit version of the 7740 1.1.1.2.2.2 bouyer local C library (utclib.c) 7741 1.1.1.2.2.2 bouyer 7742 1.1.1.2.2.2 bouyer 7743 1.1.1.2.2.2 bouyer 2) Linux 7744 1.1.1.2.2.2 bouyer 7745 1.1.1.2.2.2 bouyer EC Driver: No longer attempts to acquire the Global Lock at 7746 1.1.1.2.2.2 bouyer interrupt level. 7747 1.1.1.2.2.2 bouyer 7748 1.1.1.2.2.2 bouyer 7749 1.1.1.2.2.2 bouyer 3) iASL Compiler/Disassembler 7750 1.1.1.2.2.2 bouyer 7751 1.1.1.2.2.2 bouyer Implemented ACPI 2.0B grammar change that disallows all Type 1 and 7752 1.1.1.2.2.2 bouyer 2 opcodes outside of a control method. This means that the 7753 1.1.1.2.2.2 bouyer "executable" operators (versus the "namespace" operators) cannot 7754 1.1.1.2.2.2 bouyer be used at the table level; they can only be used within a control 7755 1.1.1.2.2.2 bouyer method. 7756 1.1.1.2.2.2 bouyer 7757 1.1.1.2.2.2 bouyer Implemented the restriction on the Scope() operator where the 7758 1.1.1.2.2.2 bouyer target must already exist in the namespace at the time the 7759 1.1.1.2.2.2 bouyer operator is encountered (during ASL compilation). In other words, 7760 1.1.1.2.2.2 bouyer forward references are not allowed and Scope() cannot create a new 7761 1.1.1.2.2.2 bouyer object. This makes the iASL compiler compatible with other ACPI 7762 1.1.1.2.2.2 bouyer implementations and makes the Scope() implementation adhere to the 7763 1.1.1.2.2.2 bouyer ACPI specification. 7764 1.1.1.2.2.2 bouyer 7765 1.1.1.2.2.2 bouyer Fixed a problem where namepath optimization for the Alias operator 7766 1.1.1.2.2.2 bouyer was optimizing the wrong path (of the two namepaths.) This caused 7767 1.1.1.2.2.2 bouyer a "Missing alias link" error message. 7768 1.1.1.2.2.2 bouyer 7769 1.1.1.2.2.2 bouyer Fixed a problem where an "unknown reserved name" warning could be 7770 1.1.1.2.2.2 bouyer incorrectly generated for names like "_SB" when the trailing 7771 1.1.1.2.2.2 bouyer underscore is not used in the original ASL. 7772 1.1.1.2.2.2 bouyer 7773 1.1.1.2.2.2 bouyer Fixed a problem where the reserved name check did not handle 7774 1.1.1.2.2.2 bouyer NamePaths with multiple NameSegs correctly. The first nameseg of 7775 1.1.1.2.2.2 bouyer the NamePath was examined instead of the last NameSeg. 7776 1.1.1.2.2.2 bouyer 7777 1.1.1.2.2.2 bouyer 7778 1.1.1.2.2.2 bouyer ---------------------------------------- 7779 1.1.1.2.2.2 bouyer 7780 1.1.1.2.2.2 bouyer 02 October 2002.

Common procedure generates and prints the lookup name as 7803 1.1.1.2.2.2 bouyer well as the formatted status. 7804 1.1.1.2.2.2 bouyer 7805 1.1.1.2.2.2 bouyer Completed implementation of a new design for the Alias support 7806 1.1.1.2.2.2 bouyer within the namespace. The existing design did not handle the case 7807 1.1.1.2.2.2 bouyer where a new object was assigned to one of the two names due to the 7808 1.1.1.2.2.2 bouyer use of an explicit conversion operator, resulting in the two names 7809 1.1.1.2.2.2 bouyer pointing to two different objects. The new design simply points 7810 1.1.1.2.2.2 bouyer the Alias name to the original name node - not to the object. 7811 1.1.1.2.2.2 bouyer This results in a level of indirection that must be handled in the 7812 1.1.1.2.2.2 bouyer name resolution mechanism. 7813 1.1.1.2.2.2 bouyer 7814 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 7815 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 7816 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 7817 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 7818 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 7819 1.1.1.2.2.2 bouyer has a larger code and data size.

Summary of changes for this release. 7857 1.1.1.2.2.2 bouyer 7858 1.1.1.2.2.2 bouyer 7859 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem version 20020918: 7860 1.1.1.2.2.2 bouyer 7861 1.1.1.2.2.2 bouyer Fixed a reported problem with reference chaining (via the Index() 7862 1.1.1.2.2.2 bouyer and RefOf() operators) in the ObjectType() and SizeOf() operators. 7863 1.1.1.2.2.2 bouyer The definition of these operators includes the dereferencing of 7864 1.1.1.2.2.2 bouyer all chained references to return information on the base object. 7865 1.1.1.2.2.2 bouyer 7866 1.1.1.2.2.2 bouyer Fixed a problem with stores to indexed package elements - the 7867 1.1.1.2.2.2 bouyer existing code would not complete the store if an "implicit 7868 1.1.1.2.2.2 bouyer conversion" was not performed. In other words, if the existing 7869 1.1.1.2.2.2 bouyer object (package element) was to be replaced completely, the code 7870 1.1.1.2.2.2 bouyer didn't handle this case. 7871 1.1.1.2.2.2 bouyer 7872 1.1.1.2.2.2 bouyer Relaxed typechecking on the ASL "Scope" operator to allow the 7873 1.1.1.2.2.2 bouyer target name to refer to an object of type Integer, String, or 7874 1.1.1.2.2.2 bouyer Buffer, in addition to the scoping object types (Device, 7875 1.1.1.2.2.2 bouyer predefined Scopes, Processor, PowerResource, and ThermalZone.) 7876 1.1.1.2.2.2 bouyer This allows existing AML code that has workarounds for a bug in 7877 1.1.1.2.2.2 bouyer Windows to function properly. A warning is issued, however. This 7878 1.1.1.2.2.2 bouyer affects both the AML interpreter and the iASL compiler. Below is 7879 1.1.1.2.2.2 bouyer an example of this type of ASL code: 7880 1.1.1.2.2.2 bouyer 7881 1.1.1.2.2.2 bouyer Name(DEB,0x00) 7882 1.1.1.2.2.2 bouyer Scope(DEB) 7883 1.1.1.2.2.2 bouyer { 7884 1.1.1.2.2.2 bouyer 7885 1.1.1.2.2.2 bouyer Fixed some reported problems with 64-bit integer support in the 7886 1.1.1.2.2.2 bouyer local implementation of C library functions (clib.c) 7887 1.1.1.2.2.2 bouyer 7888 1.1.1.2.2.2 bouyer 7889 1.1.1.2.2.2 bouyer 2) Linux 7890 1.1.1.2.2.2 bouyer 7891 1.1.1.2.2.2 bouyer Use ACPI fix map region instead of IOAPIC region, since it is 7892 1.1.1.2.2.2 bouyer undefined in non-SMP. 7893 1.1.1.2.2.2 bouyer 7894 1.1.1.2.2.2 bouyer Ensure that the SCI has the proper polarity and trigger, even on 7895 1.1.1.2.2.2 bouyer systems that do not have an interrupt override entry in the MADT. 7896 1.1.1.2.2.2 bouyer 7897 1.1.1.2.2.2 bouyer 2.5 big driver reorganization (Pat Mochel) 7898 1.1.1.2.2.2 bouyer 7899 1.1.1.2.2.2 bouyer Use early table mapping code from acpitable.c (Andi Kleen) 7900 1.1.1.2.2.2 bouyer 7901 1.1.1.2.2.2 bouyer New blacklist entries (Andi Kleen) 7902 1.1.1.2.2.2 bouyer 7903 1.1.1.2.2.2 bouyer Blacklist improvements. Split blacklist code out into a separate 7904 1.1.1.2.2.2 bouyer file. Move checking the blacklist to very early. Previously, we 7905 1.1.1.2.2.2 bouyer would use ACPI tables, and then halfway through init, check the 7906 1.1.1.2.2.2 bouyer blacklist -- too late. Now, it's early enough to completely fall- 7907 1.1.1.2.2.2 bouyer back to non-ACPI. 7908 1.1.1.2.2.2 bouyer 7909 1.1.1.2.2.2 bouyer 7910 1.1.1.2.2.2 bouyer 3) iASL Compiler/Disassembler version 20020918: 7911 1.1.1.2.2.2 bouyer 7912 1.1.1.2.2.2 bouyer Fixed a problem where the typechecking code didn't know that an 7913 1.1.1.2.2.2 bouyer alias could point to a method. In other words, aliases were not 7914 1.1.1.2.2.2 bouyer being dereferenced during typechecking. 7915 1.1.1.2.2.2 bouyer 7916 1.1.1.2.2.2 bouyer 7917 1.1.1.2.2.2 bouyer ---------------------------------------- 7918 1.1.1.2.2.2 bouyer 29 August 2002. Summary of changes for this release. 7919 1.1.1.2.2.2 bouyer 7920 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020829: 7921 1.1.1.2.2.2 bouyer 7922 1.1.1.2.2.2 bouyer If the target of a Scope() operator already exists, it must be an 7923 1.1.1.2.2.2 bouyer object type that actually opens a scope -- such as a Device, 7924 1.1.1.2.2.2 bouyer Method, Scope, etc. This is a fatal runtime error. Similar error 7925 1.1.1.2.2.2 bouyer check has been added to the iASL compiler also. 7926 1.1.1.2.2.2 bouyer 7927 1.1.1.2.2.2 bouyer Tightened up the namespace load to disallow multiple names in the 7928 1.1.1.2.2.2 bouyer same scope. This previously was allowed if both objects were of 7929 1.1.1.2.2.2 bouyer the same type. (i.e., a lookup was the same as entering a new 7930 1.1.1.2.2.2 bouyer name). 7931 1.1.1.2.2.2 bouyer 7932 1.1.1.2.2.2 bouyer 7933 1.1.1.2.2.2 bouyer 2) Linux 7934 1.1.1.2.2.2 bouyer 7935 1.1.1.2.2.2 bouyer Ensure that the ACPI interrupt has the proper trigger and 7936 1.1.1.2.2.2 bouyer polarity. 7937 1.1.1.2.2.2 bouyer 7938 1.1.1.2.2.2 bouyer local_irq_disable is extraneous. (Matthew Wilcox) 7939 1.1.1.2.2.2 bouyer 7940 1.1.1.2.2.2 bouyer Make "acpi=off" actually do what it says, and not use the ACPI 7941 1.1.1.2.2.2 bouyer interpreter *or* the tables. 7942 1.1.1.2.2.2 bouyer 7943 1.1.1.2.2.2 bouyer Added arch-neutral support for parsing SLIT and SRAT tables (Kochi 7944 1.1.1.2.2.2 bouyer Takayoshi) 7945 1.1.1.2.2.2 bouyer 7946 1.1.1.2.2.2 bouyer 7947 1.1.1.2.2.2 bouyer 3) iASL Compiler/Disassembler Version 20020829: 7948 1.1.1.2.2.2 bouyer 7949 1.1.1.2.2.2 bouyer Implemented namepath optimization for name declarations. For 7950 1.1.1.2.2.2 bouyer example, a declaration like "Method (\_SB_.ABCD)" would get 7951 1.1.1.2.2.2 bouyer optimized to "Method (ABCD)" if the declaration is within the 7952 1.1.1.2.2.2 bouyer \_SB_ scope. This optimization is in addition to the named 7953 1.1.1.2.2.2 bouyer reference path optimization first released in the previous 7954 1.1.1.2.2.2 bouyer version. This would seem to complete all possible optimizations 7955 1.1.1.2.2.2 bouyer for namepaths within the ASL/AML. 7956 1.1.1.2.2.2 bouyer 7957 1.1.1.2.2.2 bouyer If the target of a Scope() operator already exists, it must be an 7958 1.1.1.2.2.2 bouyer object type that actually opens a scope -- such as a Device, 7959 1.1.1.2.2.2 bouyer Method, Scope, etc. 7960 1.1.1.2.2.2 bouyer 7961 1.1.1.2.2.2 bouyer Implemented a check and warning for unreachable code in the same 7962 1.1.1.2.2.2 bouyer block below a Return() statement. 7963 1.1.1.2.2.2 bouyer 7964 1.1.1.2.2.2 bouyer Fixed a problem where the listing file was not generated if the 7965 1.1.1.2.2.2 bouyer compiler aborted if the maximum error count was exceeded (200). 7966 1.1.1.2.2.2 bouyer 7967 1.1.1.2.2.2 bouyer Fixed a problem where the typechecking of method return values was 7968 1.1.1.2.2.2 bouyer broken. This includes the check for a return value when the 7969 1.1.1.2.2.2 bouyer method is invoked as a TermArg (a return value is expected.) 7970 1.1.1.2.2.2 bouyer 7971 1.1.1.2.2.2 bouyer Fixed a reported problem where EOF conditions during a quoted 7972 1.1.1.2.2.2 bouyer string or comment caused a fault. 7973 1.1.1.2.2.2 bouyer 7974 1.1.1.2.2.2 bouyer 7975 1.1.1.2.2.2 bouyer ---------------------------------------- 7976 1.1.1.2.2.2 bouyer 15 August 2002. Summary of changes for this release. 7977 1.1.1.2.2.2 bouyer 7978 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020815: 7979 1.1.1.2.2.2 bouyer 7980 1.1.1.2.2.2 bouyer Fixed a reported problem where a Store to a method argument that 7981 1.1.1.2.2.2 bouyer contains a reference did not perform the indirect store correctly. 7982 1.1.1.2.2.2 bouyer This problem was created during the conversion to the new 7983 1.1.1.2.2.2 bouyer reference object model - the indirect store to a method argument 7984 1.1.1.2.2.2 bouyer code was not updated to reflect the new model. 7985 1.1.1.2.2.2 bouyer 7986 1.1.1.2.2.2 bouyer Reworked the ACPI mode change code to better conform to ACPI 2.0, 7987 1.1.1.2.2.2 bouyer handle corner cases, and improve code legibility (Kochi Takayoshi) 7988 1.1.1.2.2.2 bouyer 7989 1.1.1.2.2.2 bouyer Fixed a problem with the pathname parsing for the carat (^) 7990 1.1.1.2.2.2 bouyer prefix. The heavy use of the carat operator by the new namepath 7991 1.1.1.2.2.2 bouyer optimization in the iASL compiler uncovered a problem with the AML 7992 1.1.1.2.2.2 bouyer interpreter handling of this prefix. In the case where one or 7993 1.1.1.2.2.2 bouyer more carats precede a single nameseg, the nameseg was treated as 7994 1.1.1.2.2.2 bouyer standalone and the search rule (to root) was inadvertently 7995 1.1.1.2.2.2 bouyer applied. This could cause both the iASL compiler and the 7996 1.1.1.2.2.2 bouyer interpreter to find the wrong object or to miss the error that 7997 1.1.1.2.2.2 bouyer should occur if the object does not exist at that exact pathname. 7998 1.1.1.2.2.2 bouyer 7999 1.1.1.2.2.2 bouyer Found and fixed the problem where the HP Pavilion DSDT would not 8000 1.1.1.2.2.2 bouyer load. This was a relatively minor tweak to the table loading code 8001 1.1.1.2.2.2 bouyer (a problem caused by the unexpected encounter with a method 8002 1.1.1.2.2.2 bouyer invocation not within a control method), but it does not solve the 8003 1.1.1.2.2.2 bouyer overall issue of the execution of AML code at the table level. 8004 1.1.1.2.2.2 bouyer This investigation is still ongoing. 8005 1.1.1.2.2.2 bouyer 8006 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8007 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8008 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8009 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8010 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8011 1.1.1.2.2.2 bouyer has a larger code and data size. Note that these values will vary 8012 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 8013 1.1.1.2.2.2 bouyer options used during generation. 8014 1.1.1.2.2.2 bouyer 8015 1.1.1.2.2.2 bouyer Previous Release 8016 1.1.1.2.2.2 bouyer Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 8017 1.1.1.2.2.2 bouyer Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 8018 1.1.1.2.2.2 bouyer Current Release: 8019 1.1.1.2.2.2 bouyer Non-Debug Version: 69.6K Code, 8.3K Data, 77.9K Total 8020 1.1.1.2.2.2 bouyer Debug Version: 150.0K Code, 61.7K Data, 211.7K Total 8021 1.1.1.2.2.2 bouyer 8022 1.1.1.2.2.2 bouyer 8023 1.1.1.2.2.2 bouyer 2) Linux 8024 1.1.1.2.2.2 bouyer 8025 1.1.1.2.2.2 bouyer Remove redundant slab.h include (Brad Hards) 8026 1.1.1.2.2.2 bouyer 8027 1.1.1.2.2.2 bouyer Fix several bugs in thermal.c (Herbert Nachtnebel) 8028 1.1.1.2.2.2 bouyer 8029 1.1.1.2.2.2 bouyer Make CONFIG_ACPI_BOOT work properly (Pavel Machek) 8030 1.1.1.2.2.2 bouyer 8031 1.1.1.2.2.2 bouyer Change acpi_system_suspend to use updated irq functions (Pavel 8032 1.1.1.2.2.2 bouyer Machek) 8033 1.1.1.2.2.2 bouyer 8034 1.1.1.2.2.2 bouyer Export acpi_get_firmware_table (Matthew Wilcox) 8035 1.1.1.2.2.2 bouyer 8036 1.1.1.2.2.2 bouyer Use proper root proc entry for ACPI (Kochi Takayoshi) 8037 1.1.1.2.2.2 bouyer 8038 1.1.1.2.2.2 bouyer Fix early-boot table parsing (Bjorn Helgaas) 8039 1.1.1.2.2.2 bouyer 8040 1.1.1.2.2.2 bouyer 8041 1.1.1.2.2.2 bouyer 3) iASL Compiler/Disassembler 8042 1.1.1.2.2.2 bouyer 8043 1.1.1.2.2.2 bouyer Reworked the compiler options to make them more consistent and to 8044 1.1.1.2.2.2 bouyer use two-letter options where appropriate. We were running out of 8045 1.1.1.2.2.2 bouyer sensible letters. This may break some makefiles, so check the 8046 1.1.1.2.2.2 bouyer current options list by invoking the compiler with no parameters. 8047 1.1.1.2.2.2 bouyer 8048 1.1.1.2.2.2 bouyer Completed the design and implementation of the ASL namepath 8049 1.1.1.2.2.2 bouyer optimization option for the compiler. This option optimizes all 8050 1.1.1.2.2.2 bouyer references to named objects to the shortest possible path. The 8051 1.1.1.2.2.2 bouyer first attempt tries to utilize a single nameseg (4 characters) and 8052 1.1.1.2.2.2 bouyer the "search-to-root" algorithm used by the interpreter. If that 8053 1.1.1.2.2.2 bouyer cannot be used (because either the name is not in the search path 8054 1.1.1.2.2.2 bouyer or there is a conflict with another object with the same name), 8055 1.1.1.2.2.2 bouyer the pathname is optimized using the carat prefix (usually a 8056 1.1.1.2.2.2 bouyer shorter string than specifying the entire path from the root.) 8057 1.1.1.2.2.2 bouyer 8058 1.1.1.2.2.2 bouyer Implemented support to obtain the DSDT from the Windows registry 8059 1.1.1.2.2.2 bouyer (when the disassembly option is specified with no input file). 8060 1.1.1.2.2.2 bouyer Added this code as the implementation for AcpiOsTableOverride in 8061 1.1.1.2.2.2 bouyer the Windows OSL. Migrated the 16-bit code (used in the AcpiDump 8062 1.1.1.2.2.2 bouyer utility) to scan memory for the DSDT to the AcpiOsTableOverride 8063 1.1.1.2.2.2 bouyer function in the DOS OSL to make the disassembler truly OS 8064 1.1.1.2.2.2 bouyer independent. 8065 1.1.1.2.2.2 bouyer 8066 1.1.1.2.2.2 bouyer Implemented a new option to disassemble and compile in one step. 8067 1.1.1.2.2.2 bouyer When used without an input filename, this option will grab the 8068 1.1.1.2.2.2 bouyer DSDT from the local machine, disassemble it, and compile it in one 8069 1.1.1.2.2.2 bouyer step. 8070 1.1.1.2.2.2 bouyer 8071 1.1.1.2.2.2 bouyer Added a warning message for invalid escapes (a backslash followed 8072 1.1.1.2.2.2 bouyer by any character other than the allowable escapes). This catches 8073 1.1.1.2.2.2 bouyer the quoted string error "\_SB_" (which should be "\\_SB_" ). 8074 1.1.1.2.2.2 bouyer 8075 1.1.1.2.2.2 bouyer Also, there are numerous instances in the ACPI specification where 8076 1.1.1.2.2.2 bouyer this error occurs. 8077 1.1.1.2.2.2 bouyer 8078 1.1.1.2.2.2 bouyer Added a compiler option to disable all optimizations. This is 8079 1.1.1.2.2.2 bouyer basically the "compatibility mode" because by using this option, 8080 1.1.1.2.2.2 bouyer the AML code will come out exactly the same as other ASL 8081 1.1.1.2.2.2 bouyer compilers. 8082 1.1.1.2.2.2 bouyer 8083 1.1.1.2.2.2 bouyer Added error messages for incorrectly ordered dependent resource 8084 1.1.1.2.2.2 bouyer functions. This includes: missing EndDependentFn macro at end of 8085 1.1.1.2.2.2 bouyer dependent resource list, nested dependent function macros (both 8086 1.1.1.2.2.2 bouyer start and end), and missing StartDependentFn macro. These are 8087 1.1.1.2.2.2 bouyer common errors that should be caught at compile time. 8088 1.1.1.2.2.2 bouyer 8089 1.1.1.2.2.2 bouyer Implemented _OSI support for the disassembler and compiler. _OSI 8090 1.1.1.2.2.2 bouyer must be included in the namespace for proper disassembly (because 8091 1.1.1.2.2.2 bouyer the disassembler must know the number of arguments.) 8092 1.1.1.2.2.2 bouyer 8093 1.1.1.2.2.2 bouyer Added an "optimization" message type that is optional (off by 8094 1.1.1.2.2.2 bouyer default). This message is used for all optimizations - including 8095 1.1.1.2.2.2 bouyer constant folding, integer optimization, and namepath optimization. 8096 1.1.1.2.2.2 bouyer 8097 1.1.1.2.2.2 bouyer ---------------------------------------- 8098 1.1.1.2.2.2 bouyer 25 July 2002. Summary of changes for this release. 8099 1.1.1.2.2.2 bouyer 8100 1.1.1.2.2.2 bouyer 8101 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020725: 8102 1.1.1.2.2.2 bouyer 8103 1.1.1.2.2.2 bouyer The AML Disassembler has been enhanced to produce compilable ASL 8104 1.1.1.2.2.2 bouyer code and has been integrated into the iASL compiler (see below) as 8105 1.1.1.2.2.2 bouyer well as the single-step disassembly for the AML debugger and the 8106 1.1.1.2.2.2 bouyer disassembler for the AcpiDump utility. All ACPI 2.0A opcodes, 8107 1.1.1.2.2.2 bouyer resource templates and macros are fully supported. The 8108 1.1.1.2.2.2 bouyer disassembler has been tested on over 30 different AML files, 8109 1.1.1.2.2.2 bouyer producing identical AML when the resulting disassembled ASL file 8110 1.1.1.2.2.2 bouyer is recompiled with the same ASL compiler. 8111 1.1.1.2.2.2 bouyer 8112 1.1.1.2.2.2 bouyer Modified the Resource Manager to allow zero interrupts and zero 8113 1.1.1.2.2.2 bouyer dma channels during the GetCurrentResources call. This was 8114 1.1.1.2.2.2 bouyer causing problems on some platforms. 8115 1.1.1.2.2.2 bouyer 8116 1.1.1.2.2.2 bouyer Added the AcpiOsRedirectOutput interface to the OSL to simplify 8117 1.1.1.2.2.2 bouyer output redirection for the AcpiOsPrintf and AcpiOsVprintf 8118 1.1.1.2.2.2 bouyer interfaces. 8119 1.1.1.2.2.2 bouyer 8120 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8121 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8122 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8123 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8124 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8125 1.1.1.2.2.2 bouyer has a larger code and data size. Note that these values will vary 8126 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 8127 1.1.1.2.2.2 bouyer options used during generation. 8128 1.1.1.2.2.2 bouyer 8129 1.1.1.2.2.2 bouyer Previous Release 8130 1.1.1.2.2.2 bouyer Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 8131 1.1.1.2.2.2 bouyer Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 8132 1.1.1.2.2.2 bouyer Current Release: 8133 1.1.1.2.2.2 bouyer Non-Debug Version: 69.1K Code, 8.2K Data, 77.3K Total 8134 1.1.1.2.2.2 bouyer Debug Version: 149.4K Code, 61.6K Data, 211.0K Total 8135 1.1.1.2.2.2 bouyer 8136 1.1.1.2.2.2 bouyer 8137 1.1.1.2.2.2 bouyer 2) Linux 8138 1.1.1.2.2.2 bouyer 8139 1.1.1.2.2.2 bouyer Fixed a panic in the EC driver (Dominik Brodowski) 8140 1.1.1.2.2.2 bouyer 8141 1.1.1.2.2.2 bouyer Implemented checksum of the R/XSDT itself during Linux table scan 8142 1.1.1.2.2.2 bouyer (Richard Schaal) 8143 1.1.1.2.2.2 bouyer 8144 1.1.1.2.2.2 bouyer 8145 1.1.1.2.2.2 bouyer 3) iASL compiler 8146 1.1.1.2.2.2 bouyer 8147 1.1.1.2.2.2 bouyer The AML disassembler is integrated into the compiler. The "-d" 8148 1.1.1.2.2.2 bouyer option invokes the disassembler to completely disassemble an 8149 1.1.1.2.2.2 bouyer input AML file, producing as output a text ASL file with the 8150 1.1.1.2.2.2 bouyer extension ".dsl" (to avoid name collisions with existing .asl 8151 1.1.1.2.2.2 bouyer source files.) A future enhancement will allow the disassembler 8152 1.1.1.2.2.2 bouyer to obtain the BIOS DSDT from the registry under Windows. 8153 1.1.1.2.2.2 bouyer 8154 1.1.1.2.2.2 bouyer Fixed a problem with the VendorShort and VendorLong resource 8155 1.1.1.2.2.2 bouyer descriptors where an invalid AML sequence was created. 8156 1.1.1.2.2.2 bouyer 8157 1.1.1.2.2.2 bouyer Implemented a fix for BufferData term in the ASL parser. It was 8158 1.1.1.2.2.2 bouyer inadvertently defined twice, allowing invalid syntax to pass and 8159 1.1.1.2.2.2 bouyer causing reduction conflicts. 8160 1.1.1.2.2.2 bouyer 8161 1.1.1.2.2.2 bouyer Fixed a problem where the Ones opcode could get converted to a 8162 1.1.1.2.2.2 bouyer value of zero if "Ones" was used where a byte, word or dword value 8163 1.1.1.2.2.2 bouyer was expected.

Summary of changes for this release. 8170 1.1.1.2.2.2 bouyer 8171 1.1.1.2.2.2 bouyer 8172 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020702: 8173 1.1.1.2.2.2 bouyer 8174 1.1.1.2.2.2 bouyer The Table Manager code has been restructured to add several new 8175 1.1.1.2.2.2 bouyer features. Tables that are not required by the core subsystem 8176 1.1.1.2.2.2 bouyer (other than the FADT, DSDT, FACS, PSDTs, etc.) are no longer 8177 1.1.1.2.2.2 bouyer validated in any way and are returned from AcpiGetFirmwareTable if 8178 1.1.1.2.2.2 bouyer requested. The AcpiOsTableOverride interface is now called for 8179 1.1.1.2.2.2 bouyer each table that is loaded by the subsystem in order to allow the 8180 1.1.1.2.2.2 bouyer host to override any table it chooses. Previously, only the DSDT 8181 1.1.1.2.2.2 bouyer could be overridden. Added one new files, tbrsdt.c and 8182 1.1.1.2.2.2 bouyer tbgetall.c. 8183 1.1.1.2.2.2 bouyer 8184 1.1.1.2.2.2 bouyer Fixed a problem with the conversion of internal package objects to 8185 1.1.1.2.2.2 bouyer external objects (when a package is returned from a control 8186 1.1.1.2.2.2 bouyer method.) The return buffer length was set to zero instead of the 8187 1.1.1.2.2.2 bouyer proper length of the package object. 8188 1.1.1.2.2.2 bouyer 8189 1.1.1.2.2.2 bouyer Fixed a reported problem with the use of the RefOf and DeRefOf 8190 1.1.1.2.2.2 bouyer operators when passing reference arguments to control methods. A 8191 1.1.1.2.2.2 bouyer new type of Reference object is used internally for references 8192 1.1.1.2.2.2 bouyer produced by the RefOf operator. 8193 1.1.1.2.2.2 bouyer 8194 1.1.1.2.2.2 bouyer Added additional error messages in the Resource Manager to explain 8195 1.1.1.2.2.2 bouyer AE_BAD_DATA errors when they occur during resource parsing. 8196 1.1.1.2.2.2 bouyer 8197 1.1.1.2.2.2 bouyer Split the AcpiEnableSubsystem into two primitives to enable a 8198 1.1.1.2.2.2 bouyer finer granularity initialization sequence. These two calls should 8199 1.1.1.2.2.2 bouyer be called in this order: AcpiEnableSubsystem (flags), 8200 1.1.1.2.2.2 bouyer AcpiInitializeObjects (flags). The flags parameter remains the 8201 1.1.1.2.2.2 bouyer same. 8202 1.1.1.2.2.2 bouyer 8203 1.1.1.2.2.2 bouyer 8204 1.1.1.2.2.2 bouyer 2) Linux 8205 1.1.1.2.2.2 bouyer 8206 1.1.1.2.2.2 bouyer Updated the ACPI utilities module to understand the new style of 8207 1.1.1.2.2.2 bouyer fully resolved package objects that are now returned from the core 8208 1.1.1.2.2.2 bouyer subsystem. This eliminates errors of the form: 8209 1.1.1.2.2.2 bouyer 8210 1.1.1.2.2.2 bouyer ACPI: PCI Interrupt Routing Table [\_SB_.PCI0.PPB_._PRT] 8211 1.1.1.2.2.2 bouyer acpi_utils-0430 [145] acpi_evaluate_reference: 8212 1.1.1.2.2.2 bouyer Invalid element in package (not a device reference) 8213 1.1.1.2.2.2 bouyer 8214 1.1.1.2.2.2 bouyer The method evaluation utility uses the new buffer allocation 8215 1.1.1.2.2.2 bouyer scheme instead of calling AcpiEvaluate Object twice. 8216 1.1.1.2.2.2 bouyer 8217 1.1.1.2.2.2 bouyer Added support for ECDT. This allows the use of the Embedded 8218 1.1.1.2.2.2 bouyer 8219 1.1.1.2.2.2 bouyer Controller before the namespace has been fully initialized, which 8220 1.1.1.2.2.2 bouyer is necessary for ACPI 2.0 support, and for some laptops to 8221 1.1.1.2.2.2 bouyer initialize properly. (Laptops using ECDT are still rare, so only 8222 1.1.1.2.2.2 bouyer limited testing was performed of the added functionality.) 8223 1.1.1.2.2.2 bouyer 8224 1.1.1.2.2.2 bouyer Fixed memory leaks in the EC driver. 8225 1.1.1.2.2.2 bouyer 8226 1.1.1.2.2.2 bouyer Eliminated a brittle code structure in acpi_bus_init(). 8227 1.1.1.2.2.2 bouyer 8228 1.1.1.2.2.2 bouyer Eliminated the acpi_evaluate() helper function in utils.c. It is 8229 1.1.1.2.2.2 bouyer no longer needed since acpi_evaluate_object can optionally 8230 1.1.1.2.2.2 bouyer allocate memory for the return object. 8231 1.1.1.2.2.2 bouyer 8232 1.1.1.2.2.2 bouyer Implemented fix for keyboard hang when getting battery readings on 8233 1.1.1.2.2.2 bouyer some systems (Stephen White) 8234 1.1.1.2.2.2 bouyer 8235 1.1.1.2.2.2 bouyer PCI IRQ routing update (Dominik Brodowski) 8236 1.1.1.2.2.2 bouyer 8237 1.1.1.2.2.2 bouyer Fix an ifdef to allow compilation on UP with LAPIC but no IOAPIC 8238 1.1.1.2.2.2 bouyer support 8239 1.1.1.2.2.2 bouyer 8240 1.1.1.2.2.2 bouyer ---------------------------------------- 8241 1.1.1.2.2.2 bouyer 11 June 2002. Summary of changes for this release. 8242 1.1.1.2.2.2 bouyer 8243 1.1.1.2.2.2 bouyer 8244 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020611: 8245 1.1.1.2.2.2 bouyer 8246 1.1.1.2.2.2 bouyer Fixed a reported problem where constants such as Zero and One 8247 1.1.1.2.2.2 bouyer appearing within _PRT packages were not handled correctly within 8248 1.1.1.2.2.2 bouyer the resource manager code. Originally reported against the ASL 8249 1.1.1.2.2.2 bouyer compiler because the code generator now optimizes integers to 8250 1.1.1.2.2.2 bouyer their minimal AML representation (i.e. AML constants if possible.) 8251 1.1.1.2.2.2 bouyer The _PRT code now handles all AML constant opcodes correctly 8252 1.1.1.2.2.2 bouyer (Zero, One, Ones, Revision). 8253 1.1.1.2.2.2 bouyer 8254 1.1.1.2.2.2 bouyer Fixed a problem with the Concatenate operator in the AML 8255 1.1.1.2.2.2 bouyer interpreter where a buffer result object was incorrectly marked as 8256 1.1.1.2.2.2 bouyer not fully evaluated, causing a run-time error of AE_AML_INTERNAL. 8257 1.1.1.2.2.2 bouyer 8258 1.1.1.2.2.2 bouyer All package sub-objects are now fully resolved before they are 8259 1.1.1.2.2.2 bouyer returned from the external ACPI interfaces. This means that name 8260 1.1.1.2.2.2 bouyer strings are resolved to object handles, and constant operators 8261 1.1.1.2.2.2 bouyer (Zero, One, Ones, Revision) are resolved to Integers. 8262 1.1.1.2.2.2 bouyer 8263 1.1.1.2.2.2 bouyer Implemented immediate resolution of the AML Constant opcodes 8264 1.1.1.2.2.2 bouyer (Zero, One, Ones, Revision) to Integer objects upon detection 8265 1.1.1.2.2.2 bouyer within the AML stream. This has simplified and reduced the 8266 1.1.1.2.2.2 bouyer generated code size of the subsystem by eliminating about 10 8267 1.1.1.2.2.2 bouyer switch statements for these constants (which previously were 8268 1.1.1.2.2.2 bouyer contained in Reference objects.) The complicating issues are that 8269 1.1.1.2.2.2 bouyer the Zero opcode is used as a "placeholder" for unspecified 8270 1.1.1.2.2.2 bouyer optional target operands and stores to constants are defined to be 8271 1.1.1.2.2.2 bouyer no-ops. 8272 1.1.1.2.2.2 bouyer 8273 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8274 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8275 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8276 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8277 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8278 1.1.1.2.2.2 bouyer has a larger code and data size. Note that these values will vary 8279 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 8280 1.1.1.2.2.2 bouyer options used during generation. 8281 1.1.1.2.2.2 bouyer 8282 1.1.1.2.2.2 bouyer Previous Release 8283 1.1.1.2.2.2 bouyer Non-Debug Version: 69.3K Code, 7.4K Data, 76.7K Total 8284 1.1.1.2.2.2 bouyer Debug Version: 143.8K Code, 58.8K Data, 202.6K Total 8285 1.1.1.2.2.2 bouyer Current Release: 8286 1.1.1.2.2.2 bouyer Non-Debug Version: 68.7K Code, 7.4K Data, 76.1K Total 8287 1.1.1.2.2.2 bouyer Debug Version: 142.9K Code, 58.7K Data, 201.6K Total 8288 1.1.1.2.2.2 bouyer 8289 1.1.1.2.2.2 bouyer 8290 1.1.1.2.2.2 bouyer 2) Linux 8291 1.1.1.2.2.2 bouyer 8292 1.1.1.2.2.2 bouyer 8293 1.1.1.2.2.2 bouyer Added preliminary support for obtaining _TRA data for PCI root 8294 1.1.1.2.2.2 bouyer bridges (Bjorn Helgaas). 8295 1.1.1.2.2.2 bouyer 8296 1.1.1.2.2.2 bouyer 8297 1.1.1.2.2.2 bouyer 3) iASL Compiler Version X2046: 8298 1.1.1.2.2.2 bouyer 8299 1.1.1.2.2.2 bouyer Fixed a problem where the "_DDN" reserved name was defined to be a 8300 1.1.1.2.2.2 bouyer control method with one argument. There are no arguments, and 8301 1.1.1.2.2.2 bouyer _DDN does not have to be a control method. 8302 1.1.1.2.2.2 bouyer 8303 1.1.1.2.2.2 bouyer Fixed a problem with the Linux version of the compiler where the 8304 1.1.1.2.2.2 bouyer source lines printed with error messages were the wrong lines. 8305 1.1.1.2.2.2 bouyer This turned out to be the "LF versus CR/LF" difference between 8306 1.1.1.2.2.2 bouyer Windows and Unix. This appears to be the longstanding issue 8307 1.1.1.2.2.2 bouyer concerning listing output and error messages. 8308 1.1.1.2.2.2 bouyer 8309 1.1.1.2.2.2 bouyer Fixed a problem with the Linux version of compiler where opcode 8310 1.1.1.2.2.2 bouyer names within error messages were wrong. This was caused by a 8311 1.1.1.2.2.2 bouyer slight difference in the output of the Flex tool on Linux versus 8312 1.1.1.2.2.2 bouyer Windows. 8313 1.1.1.2.2.2 bouyer 8314 1.1.1.2.2.2 bouyer Fixed a problem with the Linux compiler where the hex output files 8315 1.1.1.2.2.2 bouyer contained some garbage data caused by an internal buffer overrun. 8316 1.1.1.2.2.2 bouyer 8317 1.1.1.2.2.2 bouyer 8318 1.1.1.2.2.2 bouyer ---------------------------------------- 8319 1.1.1.2.2.2 bouyer 17 May 2002. Summary of changes for this release. 8320 1.1.1.2.2.2 bouyer 8321 1.1.1.2.2.2 bouyer 8322 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020517: 8323 1.1.1.2.2.2 bouyer 8324 1.1.1.2.2.2 bouyer Implemented a workaround to an BIOS bug discovered on the HP 8325 1.1.1.2.2.2 bouyer OmniBook where the FADT revision number and the table size are 8326 1.1.1.2.2.2 bouyer inconsistent (ACPI 2.0 revision vs. ACPI 1.0 table size). The new 8327 1.1.1.2.2.2 bouyer behavior is to fallback to using only the ACPI 1.0 fields of the 8328 1.1.1.2.2.2 bouyer FADT if the table is too small to be a ACPI 2.0 table as claimed 8329 1.1.1.2.2.2 bouyer by the revision number. Although this is a BIOS bug, this is a 8330 1.1.1.2.2.2 bouyer case where the workaround is simple enough and with no side 8331 1.1.1.2.2.2 bouyer effects, so it seemed prudent to add it. A warning message is 8332 1.1.1.2.2.2 bouyer issued, however. 8333 1.1.1.2.2.2 bouyer 8334 1.1.1.2.2.2 bouyer Implemented minimum size checks for the fixed-length ACPI tables - 8335 1.1.1.2.2.2 bouyer - the FADT and FACS, as well as consistency checks between the 8336 1.1.1.2.2.2 bouyer revision number and the table size. 8337 1.1.1.2.2.2 bouyer 8338 1.1.1.2.2.2 bouyer Fixed a reported problem in the table override support where the 8339 1.1.1.2.2.2 bouyer new table pointer was incorrectly treated as a physical address 8340 1.1.1.2.2.2 bouyer instead of a logical address. 8341 1.1.1.2.2.2 bouyer 8342 1.1.1.2.2.2 bouyer Eliminated the use of the AE_AML_ERROR exception and replaced it 8343 1.1.1.2.2.2 bouyer with more descriptive codes. 8344 1.1.1.2.2.2 bouyer 8345 1.1.1.2.2.2 bouyer Fixed a problem where an exception would occur if an ASL Field was 8346 1.1.1.2.2.2 bouyer defined with no named Field Units underneath it (used by some 8347 1.1.1.2.2.2 bouyer index fields). 8348 1.1.1.2.2.2 bouyer 8349 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8350 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8351 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8352 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8353 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8354 1.1.1.2.2.2 bouyer has a larger code and data size.

With this interface, the OSL can examine the 8433 1.1.1.2.2.2 bouyer version of the firmware DSDT and replace it with a different one 8434 1.1.1.2.2.2 bouyer if desired. 8435 1.1.1.2.2.2 bouyer 8436 1.1.1.2.2.2 bouyer Added new external interfaces for accessing ACPI registers from 8437 1.1.1.2.2.2 bouyer device drivers and other system software - AcpiGetRegister and 8438 1.1.1.2.2.2 bouyer AcpiSetRegister. This was simply an externalization of the 8439 1.1.1.2.2.2 bouyer existing AcpiHwBitRegister interfaces. 8440 1.1.1.2.2.2 bouyer 8441 1.1.1.2.2.2 bouyer Fixed a regression introduced in the previous build where the 8442 1.1.1.2.2.2 bouyer ASL/AML CreateField operator always returned an error, 8443 1.1.1.2.2.2 bouyer "destination must be a NS Node". 8444 1.1.1.2.2.2 bouyer 8445 1.1.1.2.2.2 bouyer Extended the maximum time (before failure) to successfully enable 8446 1.1.1.2.2.2 bouyer ACPI mode to 3 seconds. 8447 1.1.1.2.2.2 bouyer 8448 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8449 1.1.1.2.2.2 bouyer below.

We are now fully MPS and $PIR- 8468 1.1.1.2.2.2 bouyer free. While 3 out of 4 of our in-house systems work fine, the last 8469 1.1.1.2.2.2 bouyer one still hangs when testing the LAPIC timer. 8470 1.1.1.2.2.2 bouyer 8471 1.1.1.2.2.2 bouyer Renamed many files in 2.5 kernel release to omit "acpi_" from the 8472 1.1.1.2.2.2 bouyer name. 8473 1.1.1.2.2.2 bouyer 8474 1.1.1.2.2.2 bouyer Added warning on boot for Presario 711FR. 8475 1.1.1.2.2.2 bouyer 8476 1.1.1.2.2.2 bouyer Sleep improvements (Pavel Machek) 8477 1.1.1.2.2.2 bouyer 8478 1.1.1.2.2.2 bouyer ACPI can now be built without CONFIG_PCI enabled. 8479 1.1.1.2.2.2 bouyer 8480 1.1.1.2.2.2 bouyer IA64: Fixed memory map functions (JI Lee) 8481 1.1.1.2.2.2 bouyer 8482 1.1.1.2.2.2 bouyer 8483 1.1.1.2.2.2 bouyer 3) iASL Compiler Version X2043: 8484 1.1.1.2.2.2 bouyer 8485 1.1.1.2.2.2 bouyer Added support to allow the compiler to be integrated into the MS 8486 1.1.1.2.2.2 bouyer VC++ development environment for one-button compilation of single 8487 1.1.1.2.2.2 bouyer files or entire projects -- with error-to-source-line mapping. 8488 1.1.1.2.2.2 bouyer 8489 1.1.1.2.2.2 bouyer Implemented support for compile-time constant folding for the 8490 1.1.1.2.2.2 bouyer Type3, Type4, and Type5 opcodes first defined in the ACPI 2.0 8491 1.1.1.2.2.2 bouyer specification. This allows the ASL writer to use expressions 8492 1.1.1.2.2.2 bouyer instead of Integer/Buffer/String constants in terms that must 8493 1.1.1.2.2.2 bouyer evaluate to constants at compile time and will also simplify the 8494 1.1.1.2.2.2 bouyer emitted AML in any such sub-expressions that can be folded 8495 1.1.1.2.2.2 bouyer (evaluated at compile-time.) This increases the size of the 8496 1.1.1.2.2.2 bouyer compiler significantly because a portion of the ACPI CA AML 8497 1.1.1.2.2.2 bouyer interpreter is included within the compiler in order to pre- 8498 1.1.1.2.2.2 bouyer evaluate constant expressions. 8499 1.1.1.2.2.2 bouyer 8500 1.1.1.2.2.2 bouyer 8501 1.1.1.2.2.2 bouyer Fixed a problem with the "Unicode" ASL macro that caused the 8502 1.1.1.2.2.2 bouyer compiler to fault. (This macro is used in conjunction with the 8503 1.1.1.2.2.2 bouyer _STR reserved name.) 8504 1.1.1.2.2.2 bouyer 8505 1.1.1.2.2.2 bouyer Implemented an AML opcode optimization to use the Zero, One, and 8506 1.1.1.2.2.2 bouyer Ones opcodes where possible to further reduce the size of integer 8507 1.1.1.2.2.2 bouyer constants and thus reduce the overall size of the generated AML 8508 1.1.1.2.2.2 bouyer code. 8509 1.1.1.2.2.2 bouyer 8510 1.1.1.2.2.2 bouyer Implemented error checking for new reserved terms for ACPI version 8511 1.1.1.2.2.2 bouyer 2.0A. 8512 1.1.1.2.2.2 bouyer 8513 1.1.1.2.2.2 bouyer Implemented the -qr option to display the current list of ACPI 8514 1.1.1.2.2.2 bouyer reserved names known to the compiler. 8515 1.1.1.2.2.2 bouyer 8516 1.1.1.2.2.2 bouyer Implemented the -qc option to display the current list of ASL 8517 1.1.1.2.2.2 bouyer operators that are allowed within constant expressions and can 8518 1.1.1.2.2.2 bouyer therefore be folded at compile time if the operands are constants. 8519 1.1.1.2.2.2 bouyer 8520 1.1.1.2.2.2 bouyer 8521 1.1.1.2.2.2 bouyer 4) Documentation 8522 1.1.1.2.2.2 bouyer 8523 1.1.1.2.2.2 bouyer Updated the Programmer's Reference for new interfaces, data types, 8524 1.1.1.2.2.2 bouyer and memory allocation model options. 8525 1.1.1.2.2.2 bouyer 8526 1.1.1.2.2.2 bouyer Updated the iASL Compiler User Reference to apply new format and 8527 1.1.1.2.2.2 bouyer add information about new features and options. 8528 1.1.1.2.2.2 bouyer 8529 1.1.1.2.2.2 bouyer ---------------------------------------- 8530 1.1.1.2.2.2 bouyer 19 April 2002. Summary of changes for this release. 8531 1.1.1.2.2.2 bouyer 8532 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020419: 8533 1.1.1.2.2.2 bouyer 8534 1.1.1.2.2.2 bouyer The source code base for the Core Subsystem has been completely 8535 1.1.1.2.2.2 bouyer cleaned with PC-lint (FlexLint) for both 32-bit and 64-bit 8536 1.1.1.2.2.2 bouyer versions. The Lint option files used are included in the 8537 1.1.1.2.2.2 bouyer /acpi/generate/lint directory. 8538 1.1.1.2.2.2 bouyer 8539 1.1.1.2.2.2 bouyer Implemented enhanced status/error checking across the entire 8540 1.1.1.2.2.2 bouyer Hardware manager subsystem. Any hardware errors (reported from 8541 1.1.1.2.2.2 bouyer the OSL) are now bubbled up and will abort a running control 8542 1.1.1.2.2.2 bouyer method. 8543 1.1.1.2.2.2 bouyer 8544 1.1.1.2.2.2 bouyer 8545 1.1.1.2.2.2 bouyer Fixed a problem where the per-ACPI-table integer width (32 or 64) 8546 1.1.1.2.2.2 bouyer was stored only with control method nodes, causing a fault when 8547 1.1.1.2.2.2 bouyer non-control method code was executed during table loading. The 8548 1.1.1.2.2.2 bouyer solution implemented uses a global variable to indicate table 8549 1.1.1.2.2.2 bouyer width across the entire ACPI subsystem. Therefore, ACPI CA does 8550 1.1.1.2.2.2 bouyer not support mixed integer widths across different ACPI tables 8551 1.1.1.2.2.2 bouyer (DSDT, SSDT). 8552 1.1.1.2.2.2 bouyer 8553 1.1.1.2.2.2 bouyer Fixed a problem where NULL extended fields (X fields) in an ACPI 8554 1.1.1.2.2.2 bouyer 2.0 ACPI FADT caused the table load to fail. Although the 8555 1.1.1.2.2.2 bouyer existing ACPI specification is a bit fuzzy on this topic, the new 8556 1.1.1.2.2.2 bouyer behavior is to fall back on a ACPI 1.0 field if the corresponding 8557 1.1.1.2.2.2 bouyer ACPI 2.0 X field is zero (even though the table revision indicates 8558 1.1.1.2.2.2 bouyer a full ACPI 2.0 table.) The ACPI specification will be updated to 8559 1.1.1.2.2.2 bouyer clarify this issue. 8560 1.1.1.2.2.2 bouyer 8561 1.1.1.2.2.2 bouyer Fixed a problem with the SystemMemory operation region handler 8562 1.1.1.2.2.2 bouyer where memory was always accessed byte-wise even if the AML- 8563 1.1.1.2.2.2 bouyer specified access width was larger than a byte. This caused 8564 1.1.1.2.2.2 bouyer problems on systems with memory-mapped I/O. Memory is now 8565 1.1.1.2.2.2 bouyer accessed with the width specified. On systems that do not support 8566 1.1.1.2.2.2 bouyer non-aligned transfers, a check is made to guarantee proper address 8567 1.1.1.2.2.2 bouyer alignment before proceeding in order to avoid an AML-caused 8568 1.1.1.2.2.2 bouyer alignment fault within the kernel. 8569 1.1.1.2.2.2 bouyer 8570 1.1.1.2.2.2 bouyer 8571 1.1.1.2.2.2 bouyer Fixed a problem with the ExtendedIrq resource where only one byte 8572 1.1.1.2.2.2 bouyer of the 4-byte Irq field was extracted. 8573 1.1.1.2.2.2 bouyer 8574 1.1.1.2.2.2 bouyer Fixed the AcpiExDigitsNeeded() procedure to support _UID. This 8575 1.1.1.2.2.2 bouyer function was out of date and required a rewrite. 8576 1.1.1.2.2.2 bouyer 8577 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8578 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8579 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8580 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8581 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8582 1.1.1.2.2.2 bouyer has a larger code and data size. Note that these values will vary 8583 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 8584 1.1.1.2.2.2 bouyer options used during generation. 8585 1.1.1.2.2.2 bouyer 8586 1.1.1.2.2.2 bouyer Previous Release 8587 1.1.1.2.2.2 bouyer Non-Debug Version: 66.6K Code, 6.5K Data, 73.1K Total 8588 1.1.1.2.2.2 bouyer Debug Version: 139.8K Code, 57.4K Data, 197.2K Total 8589 1.1.1.2.2.2 bouyer Current Release: 8590 1.1.1.2.2.2 bouyer Non-Debug Version: 68.5K Code, 7.0K Data, 75.5K Total 8591 1.1.1.2.2.2 bouyer Debug Version: 142.4K Code, 58.3K Data, 200.7K Total 8592 1.1.1.2.2.2 bouyer 8593 1.1.1.2.2.2 bouyer 8594 1.1.1.2.2.2 bouyer 2) Linux 8595 1.1.1.2.2.2 bouyer 8596 1.1.1.2.2.2 bouyer PCI IRQ routing fixes (Dominik Brodowski) 8597 1.1.1.2.2.2 bouyer 8598 1.1.1.2.2.2 bouyer 8599 1.1.1.2.2.2 bouyer 3) iASL Compiler Version X2042: 8600 1.1.1.2.2.2 bouyer 8601 1.1.1.2.2.2 bouyer Implemented an additional compile-time error check for a field 8602 1.1.1.2.2.2 bouyer unit whose size + minimum access width would cause a run-time 8603 1.1.1.2.2.2 bouyer access beyond the end-of-region. Previously, only the field size 8604 1.1.1.2.2.2 bouyer itself was checked. 8605 1.1.1.2.2.2 bouyer 8606 1.1.1.2.2.2 bouyer The Core subsystem and iASL compiler now share a common parse 8607 1.1.1.2.2.2 bouyer object in preparation for compile-time evaluation of the type 8608 1.1.1.2.2.2 bouyer 3/4/5 ASL operators. 8609 1.1.1.2.2.2 bouyer 8610 1.1.1.2.2.2 bouyer 8611 1.1.1.2.2.2 bouyer ---------------------------------------- 8612 1.1.1.2.2.2 bouyer Summary of changes for this release: 03_29_02 8613 1.1.1.2.2.2 bouyer 8614 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem Version 20020329: 8615 1.1.1.2.2.2 bouyer 8616 1.1.1.2.2.2 bouyer Implemented support for late evaluation of TermArg operands to 8617 1.1.1.2.2.2 bouyer Buffer and Package objects. This allows complex expressions to be 8618 1.1.1.2.2.2 bouyer used in the declarations of these object types. 8619 1.1.1.2.2.2 bouyer 8620 1.1.1.2.2.2 bouyer Fixed an ACPI 1.0 compatibility issue when reading Fields. In ACPI 8621 1.1.1.2.2.2 bouyer 1.0, if the field was larger than 32 bits, it was returned as a 8622 1.1.1.2.2.2 bouyer buffer - otherwise it was returned as an integer. In ACPI 2.0, 8623 1.1.1.2.2.2 bouyer the field is returned as a buffer only if the field is larger than 8624 1.1.1.2.2.2 bouyer 64 bits. The TableRevision is now considered when making this 8625 1.1.1.2.2.2 bouyer conversion to avoid incompatibility with existing ASL code. 8626 1.1.1.2.2.2 bouyer 8627 1.1.1.2.2.2 bouyer Implemented logical addressing for AcpiOsGetRootPointer. This 8628 1.1.1.2.2.2 bouyer allows an RSDP with either a logical or physical address. With 8629 1.1.1.2.2.2 bouyer this support, the host OS can now override all ACPI tables with 8630 1.1.1.2.2.2 bouyer one logical RSDP. Includes implementation of "typed" pointer 8631 1.1.1.2.2.2 bouyer support to allow a common data type for both physical and logical 8632 1.1.1.2.2.2 bouyer pointers internally.

This allows a 8946 1.1.1.2.2.2 bouyer table to be loaded from a named field, in addition to loading a 8947 1.1.1.2.2.2 bouyer table directly from an Operation Region. 8948 1.1.1.2.2.2 bouyer 8949 1.1.1.2.2.2 bouyer Implemented timeout and handle support in the external Global Lock 8950 1.1.1.2.2.2 bouyer interfaces. 8951 1.1.1.2.2.2 bouyer 8952 1.1.1.2.2.2 bouyer Fixed a problem in the AcpiDump utility where pathnames were no 8953 1.1.1.2.2.2 bouyer longer being generated correctly during the dump of named objects. 8954 1.1.1.2.2.2 bouyer 8955 1.1.1.2.2.2 bouyer Modified the AML debugger to give a full display of if/while 8956 1.1.1.2.2.2 bouyer predicates instead of just one AML opcode at a time. (The 8957 1.1.1.2.2.2 bouyer predicate can have several nested ASL statements.) The old method 8958 1.1.1.2.2.2 bouyer was confusing during single stepping. 8959 1.1.1.2.2.2 bouyer 8960 1.1.1.2.2.2 bouyer Code and Data Size: Current core subsystem library sizes are shown 8961 1.1.1.2.2.2 bouyer below. These are the code and data sizes for the acpica.lib 8962 1.1.1.2.2.2 bouyer produced by the Microsoft Visual C++ 6.0 compiler, and these 8963 1.1.1.2.2.2 bouyer values do not include any ACPI driver or OSPM code. The debug 8964 1.1.1.2.2.2 bouyer version of the code includes the debug output trace mechanism and 8965 1.1.1.2.2.2 bouyer has a larger code and data size. Note that these values will vary 8966 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 8967 1.1.1.2.2.2 bouyer options used during generation. 8968 1.1.1.2.2.2 bouyer 8969 1.1.1.2.2.2 bouyer Previous Release (12_18_01) 8970 1.1.1.2.2.2 bouyer Non-Debug Version: 66.1K Code, 5.5K Data, 71.6K Total 8971 1.1.1.2.2.2 bouyer Debug Version: 138.3K Code, 55.9K Data, 194.2K Total 8972 1.1.1.2.2.2 bouyer Current Release: 8973 1.1.1.2.2.2 bouyer Non-Debug Version: 65.2K Code, 6.2K Data, 71.4K Total 8974 1.1.1.2.2.2 bouyer Debug Version: 136.9K Code, 56.4K Data, 193.3K Total 8975 1.1.1.2.2.2 bouyer 8976 1.1.1.2.2.2 bouyer 2) Linux 8977 1.1.1.2.2.2 bouyer 8978 1.1.1.2.2.2 bouyer Implemented fix for PIIX reverse throttling errata (Processor 8979 1.1.1.2.2.2 bouyer driver) 8980 1.1.1.2.2.2 bouyer 8981 1.1.1.2.2.2 bouyer Added new Limit interface (Processor and Thermal drivers) 8982 1.1.1.2.2.2 bouyer 8983 1.1.1.2.2.2 bouyer New thermal policy (Thermal driver) 8984 1.1.1.2.2.2 bouyer 8985 1.1.1.2.2.2 bouyer Many updates to /proc 8986 1.1.1.2.2.2 bouyer 8987 1.1.1.2.2.2 bouyer Battery "low" event support (Battery driver) 8988 1.1.1.2.2.2 bouyer 8989 1.1.1.2.2.2 bouyer Supports ACPI PCI IRQ routing (PCI Link and PCI root drivers) 8990 1.1.1.2.2.2 bouyer 8991 1.1.1.2.2.2 bouyer IA32 - IA64 initialization unification, no longer experimental 8992 1.1.1.2.2.2 bouyer 8993 1.1.1.2.2.2 bouyer Menuconfig options redesigned 8994 1.1.1.2.2.2 bouyer 8995 1.1.1.2.2.2 bouyer 3) ASL Compiler, version X2037: 8996 1.1.1.2.2.2 bouyer 8997 1.1.1.2.2.2 bouyer Implemented several new output features to simplify integration of 8998 1.1.1.2.2.2 bouyer AML code into firmware: 1) Output the AML in C source code with 8999 1.1.1.2.2.2 bouyer labels for each named ASL object. The original ASL source code 9000 1.1.1.2.2.2 bouyer is interleaved as C comments. 2) Output the AML in ASM source code 9001 1.1.1.2.2.2 bouyer with labels and interleaved ASL source. 3) Output the AML in 9002 1.1.1.2.2.2 bouyer raw hex table form, in either C or ASM. 9003 1.1.1.2.2.2 bouyer 9004 1.1.1.2.2.2 bouyer Implemented support for optional string parameters to the 9005 1.1.1.2.2.2 bouyer LoadTable operator. 9006 1.1.1.2.2.2 bouyer 9007 1.1.1.2.2.2 bouyer Completed support for embedded escape sequences within string 9008 1.1.1.2.2.2 bouyer literals. The compiler now supports all single character escapes 9009 1.1.1.2.2.2 bouyer as well as the Octal and Hex escapes. Note: the insertion of a 9010 1.1.1.2.2.2 bouyer null byte into a string literal (via the hex/octal escape) causes 9011 1.1.1.2.2.2 bouyer the string to be immediately terminated. A warning is issued. 9012 1.1.1.2.2.2 bouyer 9013 1.1.1.2.2.2 bouyer Fixed a problem where incorrect AML was generated for the case 9014 1.1.1.2.2.2 bouyer where an ASL namepath consists of a single parent prefix ( 9015 1.1.1.2.2.2 bouyer 9016 1.1.1.2.2.2 bouyer ) with no trailing name segments. 9017 1.1.1.2.2.2 bouyer 9018 1.1.1.2.2.2 bouyer The compiler has been successfully generated with a 64-bit C 9019 1.1.1.2.2.2 bouyer compiler. 9020 1.1.1.2.2.2 bouyer 9021 1.1.1.2.2.2 bouyer 9022 1.1.1.2.2.2 bouyer 9023 1.1.1.2.2.2 bouyer 9024 1.1.1.2.2.2 bouyer ---------------------------------------- 9025 1.1.1.2.2.2 bouyer Summary of changes for this label: 12_18_01 9026 1.1.1.2.2.2 bouyer 9027 1.1.1.2.2.2 bouyer 1) Linux 9028 1.1.1.2.2.2 bouyer 9029 1.1.1.2.2.2 bouyer Enhanced blacklist with reason and severity fields.

Multiple writes are not performed. 9187 1.1.1.2.2.2 bouyer 9188 1.1.1.2.2.2 bouyer Fixed a problem where the access type used in an AccessAs ASL 9189 1.1.1.2.2.2 bouyer operator was not recorded correctly into the field object. 9190 1.1.1.2.2.2 bouyer 9191 1.1.1.2.2.2 bouyer Fixed a problem where ASL Event objects were created in a 9192 1.1.1.2.2.2 bouyer signalled state. Events are now created in an unsignalled state. 9193 1.1.1.2.2.2 bouyer 9194 1.1.1.2.2.2 bouyer The internal object cache is now purged after table loading and 9195 1.1.1.2.2.2 bouyer initialization to reduce the use of dynamic kernel memory -- on 9196 1.1.1.2.2.2 bouyer the assumption that object use is greatest during the parse phase 9197 1.1.1.2.2.2 bouyer of the entire table (versus the run-time use of individual control 9198 1.1.1.2.2.2 bouyer methods.) 9199 1.1.1.2.2.2 bouyer 9200 1.1.1.2.2.2 bouyer ACPI 2.0 variable-length packages are now fully operational. 9201 1.1.1.2.2.2 bouyer 9202 1.1.1.2.2.2 bouyer Code and Data Size: Code and Data optimizations have permitted new 9203 1.1.1.2.2.2 bouyer feature development with an actual reduction in the library size. 9204 1.1.1.2.2.2 bouyer Current core subsystem library sizes are shown below. These are 9205 1.1.1.2.2.2 bouyer the code and data sizes for the acpica.lib produced by the 9206 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 compiler, and these values do not include 9207 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code 9208 1.1.1.2.2.2 bouyer includes the debug output trace mechanism and has a larger code 9209 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the 9210 1.1.1.2.2.2 bouyer efficiency of the compiler and the compiler options used during 9211 1.1.1.2.2.2 bouyer generation. 9212 1.1.1.2.2.2 bouyer 9213 1.1.1.2.2.2 bouyer Previous Release (11_09_01): 9214 1.1.1.2.2.2 bouyer Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 9215 1.1.1.2.2.2 bouyer Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 9216 1.1.1.2.2.2 bouyer 9217 1.1.1.2.2.2 bouyer Current Release: 9218 1.1.1.2.2.2 bouyer Non-Debug Version: 64.1K Code, 5.3K Data, 69.4K Total 9219 1.1.1.2.2.2 bouyer Debug Version: 135.1K Code, 55.4K Data, 190.5K Total 9220 1.1.1.2.2.2 bouyer 9221 1.1.1.2.2.2 bouyer 2) Linux: 9222 1.1.1.2.2.2 bouyer 9223 1.1.1.2.2.2 bouyer Enhanced the ACPI boot-time initialization code to allow the use 9224 1.1.1.2.2.2 bouyer of Local APIC tables for processor enumeration on IA-32, and to 9225 1.1.1.2.2.2 bouyer pave the way for a fully MPS-free boot (on SMP systems) in the 9226 1.1.1.2.2.2 bouyer near future. This functionality replaces 9227 1.1.1.2.2.2 bouyer arch/i386/kernel/acpitables.c, which was introduced in an earlier 9228 1.1.1.2.2.2 bouyer 2.4.15-preX release. To enable this feature you must add 9229 1.1.1.2.2.2 bouyer "acpi_boot=on" to the kernel command line -- see the help entry 9230 1.1.1.2.2.2 bouyer for CONFIG_ACPI_BOOT for more information. An IA-64 release is in 9231 1.1.1.2.2.2 bouyer the works... 9232 1.1.1.2.2.2 bouyer 9233 1.1.1.2.2.2 bouyer Restructured the configuration options to allow boot-time table 9234 1.1.1.2.2.2 bouyer parsing support without inclusion of the ACPI Interpreter (and 9235 1.1.1.2.2.2 bouyer other) code. 9236 1.1.1.2.2.2 bouyer 9237 1.1.1.2.2.2 bouyer NOTE: This release does not include fixes for the reported events, 9238 1.1.1.2.2.2 bouyer power-down, and thermal passive cooling issues (coming soon). 9239 1.1.1.2.2.2 bouyer 9240 1.1.1.2.2.2 bouyer 3) ASL Compiler: 9241 1.1.1.2.2.2 bouyer 9242 1.1.1.2.2.2 bouyer Added additional typechecking for Fields within restricted access 9243 1.1.1.2.2.2 bouyer Operation Regions. All fields within EC and CMOS regions must be 9244 1.1.1.2.2.2 bouyer declared with ByteAcc. All fields withing SMBus regions must be 9245 1.1.1.2.2.2 bouyer declared with the BufferAcc access type. 9246 1.1.1.2.2.2 bouyer 9247 1.1.1.2.2.2 bouyer Fixed a problem where the listing file output of control methods 9248 1.1.1.2.2.2 bouyer no longer interleaved the actual AML code with the ASL source 9249 1.1.1.2.2.2 bouyer code. 9250 1.1.1.2.2.2 bouyer 9251 1.1.1.2.2.2 bouyer 9252 1.1.1.2.2.2 bouyer 9253 1.1.1.2.2.2 bouyer 9254 1.1.1.2.2.2 bouyer ---------------------------------------- 9255 1.1.1.2.2.2 bouyer Summary of changes for this label: 11_09_01 9256 1.1.1.2.2.2 bouyer 9257 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 9258 1.1.1.2.2.2 bouyer 9259 1.1.1.2.2.2 bouyer Implemented ACPI 2.0-defined support for writes to fields with a 9260 1.1.1.2.2.2 bouyer Buffer, String, or Integer source operand that is smaller than the 9261 1.1.1.2.2.2 bouyer target field. In these cases, the source operand is zero-extended 9262 1.1.1.2.2.2 bouyer to fill the target field. 9263 1.1.1.2.2.2 bouyer 9264 1.1.1.2.2.2 bouyer Fixed a problem where a Field starting bit offset (within the 9265 1.1.1.2.2.2 bouyer parent operation region) was calculated incorrectly if the 9266 1.1.1.2.2.2 bouyer 9267 1.1.1.2.2.2 bouyer alignment of the field differed from the access width. This 9268 1.1.1.2.2.2 bouyer affected CreateWordField, CreateDwordField, CreateQwordField, and 9269 1.1.1.2.2.2 bouyer possibly other fields that use the "AccessAny" keyword. 9270 1.1.1.2.2.2 bouyer 9271 1.1.1.2.2.2 bouyer Fixed a problem introduced in the 11_02_01 release where indirect 9272 1.1.1.2.2.2 bouyer stores through method arguments did not operate correctly. 9273 1.1.1.2.2.2 bouyer 9274 1.1.1.2.2.2 bouyer 2) Linux: 9275 1.1.1.2.2.2 bouyer 9276 1.1.1.2.2.2 bouyer Implemented boot-time ACPI table parsing support 9277 1.1.1.2.2.2 bouyer (CONFIG_ACPI_BOOT) for IA32 and IA64 UP/SMP systems. This code 9278 1.1.1.2.2.2 bouyer facilitates the use of ACPI tables (e.g. MADT, SRAT) rather than 9279 1.1.1.2.2.2 bouyer legacy BIOS interfaces (e.g. MPS) for the configuration of system 9280 1.1.1.2.2.2 bouyer processors, memory, and interrupts during setup_arch(). Note that 9281 1.1.1.2.2.2 bouyer this patch does not include the required architecture-specific 9282 1.1.1.2.2.2 bouyer changes required to apply this information -- subsequent patches 9283 1.1.1.2.2.2 bouyer will be posted for both IA32 and IA64 to achieve this. 9284 1.1.1.2.2.2 bouyer 9285 1.1.1.2.2.2 bouyer Added low-level sleep support for IA32 platforms, courtesy of Pat 9286 1.1.1.2.2.2 bouyer Mochel. This allows IA32 systems to transition to/from various 9287 1.1.1.2.2.2 bouyer sleeping states (e.g. S1, S3), although the lack of a centralized 9288 1.1.1.2.2.2 bouyer driver model and power-manageable drivers will prevent its 9289 1.1.1.2.2.2 bouyer (successful) use on most systems. 9290 1.1.1.2.2.2 bouyer 9291 1.1.1.2.2.2 bouyer Revamped the ACPI 'menuconfig' layout: created new "ACPI Support" 9292 1.1.1.2.2.2 bouyer submenu, unified IA32 and IA64 options, added new "Boot using ACPI 9293 1.1.1.2.2.2 bouyer tables" option, etc. 9294 1.1.1.2.2.2 bouyer 9295 1.1.1.2.2.2 bouyer Increased the default timeout for the EC driver from 1ms to 10ms 9296 1.1.1.2.2.2 bouyer (1000 cycles of 10us) to try to address AE_TIME errors during EC 9297 1.1.1.2.2.2 bouyer transactions. 9298 1.1.1.2.2.2 bouyer 9299 1.1.1.2.2.2 bouyer ---------------------------------------- 9300 1.1.1.2.2.2 bouyer Summary of changes for this label: 11_02_01 9301 1.1.1.2.2.2 bouyer 9302 1.1.1.2.2.2 bouyer 1) ACPI CA Core Subsystem: 9303 1.1.1.2.2.2 bouyer 9304 1.1.1.2.2.2 bouyer ACPI 2.0 Support: Implemented ACPI 2.0 64-bit Field access 9305 1.1.1.2.2.2 bouyer (QWordAcc keyword). All ACPI 2.0 64-bit support is now 9306 1.1.1.2.2.2 bouyer implemented. 9307 1.1.1.2.2.2 bouyer 9308 1.1.1.2.2.2 bouyer OSL Interfaces: Several of the OSL (AcpiOs*) interfaces required 9309 1.1.1.2.2.2 bouyer changes to support ACPI 2.0 Qword field access. Read/Write 9310 1.1.1.2.2.2 bouyer PciConfiguration(), Read/Write Memory(), and Read/Write Port() now 9311 1.1.1.2.2.2 bouyer accept an ACPI_INTEGER (64 bits) as the value parameter. Also, 9312 1.1.1.2.2.2 bouyer the value parameter for the address space handler interface is now 9313 1.1.1.2.2.2 bouyer an ACPI_INTEGER. OSL implementations of these interfaces must now 9314 1.1.1.2.2.2 bouyer handle the case where the Width parameter is 64. 9315 1.1.1.2.2.2 bouyer 9316 1.1.1.2.2.2 bouyer Index Fields: Fixed a problem where unaligned bit assembly and 9317 1.1.1.2.2.2 bouyer disassembly for IndexFields was not supported correctly. 9318 1.1.1.2.2.2 bouyer 9319 1.1.1.2.2.2 bouyer Index and Bank Fields: Nested Index and Bank Fields are now 9320 1.1.1.2.2.2 bouyer supported. During field access, a check is performed to ensure 9321 1.1.1.2.2.2 bouyer that the value written to an Index or Bank register is not out of 9322 1.1.1.2.2.2 bouyer the range of the register. The Index (or Bank) register is 9323 1.1.1.2.2.2 bouyer written before each access to the field data. Future support will 9324 1.1.1.2.2.2 bouyer include allowing individual IndexFields to be wider than the 9325 1.1.1.2.2.2 bouyer DataRegister width. 9326 1.1.1.2.2.2 bouyer 9327 1.1.1.2.2.2 bouyer Fields: Fixed a problem where the AML interpreter was incorrectly 9328 1.1.1.2.2.2 bouyer attempting to write beyond the end of a Field/OpRegion. This was 9329 1.1.1.2.2.2 bouyer a boundary case that occurred when a DWORD field was written to a 9330 1.1.1.2.2.2 bouyer BYTE access OpRegion, forcing multiple writes and causing the 9331 1.1.1.2.2.2 bouyer interpreter to write one datum too many. 9332 1.1.1.2.2.2 bouyer 9333 1.1.1.2.2.2 bouyer Fields: Fixed a problem with Field/OpRegion access where the 9334 1.1.1.2.2.2 bouyer starting bit address of a field was incorrectly calculated if the 9335 1.1.1.2.2.2 bouyer current access type was wider than a byte (WordAcc, DwordAcc, or 9336 1.1.1.2.2.2 bouyer QwordAcc). 9337 1.1.1.2.2.2 bouyer 9338 1.1.1.2.2.2 bouyer Fields: Fixed a problem where forward references to individual 9339 1.1.1.2.2.2 bouyer FieldUnits (individual Field names within a Field definition) were 9340 1.1.1.2.2.2 bouyer not resolved during the AML table load. 9341 1.1.1.2.2.2 bouyer 9342 1.1.1.2.2.2 bouyer Fields: Fixed a problem where forward references from a Field 9343 1.1.1.2.2.2 bouyer definition to the parent Operation Region definition were not 9344 1.1.1.2.2.2 bouyer resolved during the AML table load. 9345 1.1.1.2.2.2 bouyer 9346 1.1.1.2.2.2 bouyer Fields: Duplicate FieldUnit names within a scope are now detected 9347 1.1.1.2.2.2 bouyer during AML table load. 9348 1.1.1.2.2.2 bouyer 9349 1.1.1.2.2.2 bouyer Acpi Interfaces: Fixed a problem where the AcpiGetName() interface 9350 1.1.1.2.2.2 bouyer returned an incorrect name for the root node. 9351 1.1.1.2.2.2 bouyer 9352 1.1.1.2.2.2 bouyer Code and Data Size: Code and Data optimizations have permitted new 9353 1.1.1.2.2.2 bouyer feature development with an actual reduction in the library size. 9354 1.1.1.2.2.2 bouyer Current core subsystem library sizes are shown below. These are 9355 1.1.1.2.2.2 bouyer the code and data sizes for the acpica.lib produced by the 9356 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 compiler, and these values do not include 9357 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code 9358 1.1.1.2.2.2 bouyer includes the debug output trace mechanism and has a larger code 9359 1.1.1.2.2.2 bouyer and data size. Note that these values will vary depending on the 9360 1.1.1.2.2.2 bouyer efficiency of the compiler and the compiler options used during 9361 1.1.1.2.2.2 bouyer generation. 9362 1.1.1.2.2.2 bouyer 9363 1.1.1.2.2.2 bouyer Previous Release (10_18_01): 9364 1.1.1.2.2.2 bouyer Non-Debug Version: 63.9K Code, 5.1K Data, 69.0K Total 9365 1.1.1.2.2.2 bouyer Debug Version: 136.7K Code, 57.4K Data, 194.2K Total 9366 1.1.1.2.2.2 bouyer 9367 1.1.1.2.2.2 bouyer Current Release: 9368 1.1.1.2.2.2 bouyer Non-Debug Version: 63.7K Code, 5.2K Data, 68.9K Total 9369 1.1.1.2.2.2 bouyer Debug Version: 134.5K Code, 55.4K Data, 189.9K Total 9370 1.1.1.2.2.2 bouyer 9371 1.1.1.2.2.2 bouyer 2) Linux: 9372 1.1.1.2.2.2 bouyer 9373 1.1.1.2.2.2 bouyer Improved /proc processor output (Pavel Machek) Re-added 9374 1.1.1.2.2.2 bouyer MODULE_LICENSE("GPL") to all modules. 9375 1.1.1.2.2.2 bouyer 9376 1.1.1.2.2.2 bouyer 3) ASL Compiler version X2030: 9377 1.1.1.2.2.2 bouyer 9378 1.1.1.2.2.2 bouyer Duplicate FieldUnit names within a scope are now detected and 9379 1.1.1.2.2.2 bouyer flagged as errors. 9380 1.1.1.2.2.2 bouyer 9381 1.1.1.2.2.2 bouyer 4) Documentation: 9382 1.1.1.2.2.2 bouyer 9383 1.1.1.2.2.2 bouyer Programmer Reference updated to reflect OSL and address space 9384 1.1.1.2.2.2 bouyer handler interface changes described above. 9385 1.1.1.2.2.2 bouyer 9386 1.1.1.2.2.2 bouyer ---------------------------------------- 9387 1.1.1.2.2.2 bouyer Summary of changes for this label: 10_18_01 9388 1.1.1.2.2.2 bouyer 9389 1.1.1.2.2.2 bouyer ACPI CA Core Subsystem: 9390 1.1.1.2.2.2 bouyer 9391 1.1.1.2.2.2 bouyer Fixed a problem with the internal object reference count mechanism 9392 1.1.1.2.2.2 bouyer that occasionally caused premature object deletion. This resolves 9393 1.1.1.2.2.2 bouyer all of the outstanding problem reports where an object is deleted 9394 1.1.1.2.2.2 bouyer in the middle of an interpreter evaluation. Although this problem 9395 1.1.1.2.2.2 bouyer only showed up in rather obscure cases, the solution to the 9396 1.1.1.2.2.2 bouyer problem involved an adjustment of all reference counts involving 9397 1.1.1.2.2.2 bouyer objects attached to namespace nodes. 9398 1.1.1.2.2.2 bouyer 9399 1.1.1.2.2.2 bouyer Fixed a problem with Field support in the interpreter where 9400 1.1.1.2.2.2 bouyer writing to an aligned field whose length is an exact multiple (2 9401 1.1.1.2.2.2 bouyer or greater) of the field access granularity would cause an attempt 9402 1.1.1.2.2.2 bouyer to write beyond the end of the field. 9403 1.1.1.2.2.2 bouyer 9404 1.1.1.2.2.2 bouyer The top level AML opcode execution functions within the 9405 1.1.1.2.2.2 bouyer interpreter have been renamed with a more meaningful and 9406 1.1.1.2.2.2 bouyer consistent naming convention. The modules exmonad.c and 9407 1.1.1.2.2.2 bouyer exdyadic.c were eliminated. New modules are exoparg1.c, 9408 1.1.1.2.2.2 bouyer exoparg2.c, exoparg3.c, and exoparg6.c. 9409 1.1.1.2.2.2 bouyer 9410 1.1.1.2.2.2 bouyer Support for the ACPI 2.0 "Mid" ASL operator has been implemented. 9411 1.1.1.2.2.2 bouyer 9412 1.1.1.2.2.2 bouyer Fixed a problem where the AML debugger was causing some internal 9413 1.1.1.2.2.2 bouyer objects to not be deleted during subsystem termination. 9414 1.1.1.2.2.2 bouyer 9415 1.1.1.2.2.2 bouyer Fixed a problem with the external AcpiEvaluateObject interface 9416 1.1.1.2.2.2 bouyer where the subsystem would fault if the named object to be 9417 1.1.1.2.2.2 bouyer evaluated refered to a constant such as Zero, Ones, etc. 9418 1.1.1.2.2.2 bouyer 9419 1.1.1.2.2.2 bouyer Fixed a problem with IndexFields and BankFields where the 9420 1.1.1.2.2.2 bouyer subsystem would fault if the index, data, or bank registers were 9421 1.1.1.2.2.2 bouyer not defined in the same scope as the field itself. 9422 1.1.1.2.2.2 bouyer 9423 1.1.1.2.2.2 bouyer Added printf format string checking for compilers that support 9424 1.1.1.2.2.2 bouyer this feature. Corrected more than 50 instances of issues with 9425 1.1.1.2.2.2 bouyer format specifiers within invocations of ACPI_DEBUG_PRINT 9426 1.1.1.2.2.2 bouyer throughout the core subsystem code. 9427 1.1.1.2.2.2 bouyer 9428 1.1.1.2.2.2 bouyer The ASL "Revision" operator now returns the ACPI support level 9429 1.1.1.2.2.2 bouyer implemented in the core - the value "2" since the ACPI 2.0 support 9430 1.1.1.2.2.2 bouyer is more than 50% implemented. 9431 1.1.1.2.2.2 bouyer 9432 1.1.1.2.2.2 bouyer Enhanced the output of the AML debugger "dump namespace" command 9433 1.1.1.2.2.2 bouyer to output in a more human-readable form. 9434 1.1.1.2.2.2 bouyer 9435 1.1.1.2.2.2 bouyer Current core subsystem library code sizes are shown below. These 9436 1.1.1.2.2.2 bouyer 9437 1.1.1.2.2.2 bouyer are the code and data sizes for the acpica.lib produced by the 9438 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 compiler, and these values do not include 9439 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code 9440 1.1.1.2.2.2 bouyer includes the full debug trace mechanism -- leading to a much 9441 1.1.1.2.2.2 bouyer 9442 1.1.1.2.2.2 bouyer larger code and data size.

This means that upon entering the 9483 1.1.1.2.2.2 bouyer sleep state, all GPEs that are not wake-enabled are disabled. 9484 1.1.1.2.2.2 bouyer When leaving the sleep state, these GPEs are reenabled. 9485 1.1.1.2.2.2 bouyer 9486 1.1.1.2.2.2 bouyer A local double-precision divide/modulo module has been added to 9487 1.1.1.2.2.2 bouyer enhance portability to OS kernels where a 64-bit math library is 9488 1.1.1.2.2.2 bouyer not available. The new module is "utmath.c". 9489 1.1.1.2.2.2 bouyer 9490 1.1.1.2.2.2 bouyer Several optimizations have been made to reduce the use of CPU 9491 1.1.1.2.2.2 bouyer stack. Originally over 2K, the maximum stack usage is now below 9492 1.1.1.2.2.2 bouyer 2K at 1860 bytes (1.82k) 9493 1.1.1.2.2.2 bouyer 9494 1.1.1.2.2.2 bouyer Fixed a problem with the AcpiGetFirmwareTable interface where the 9495 1.1.1.2.2.2 bouyer root table pointer was not mapped into a logical address properly. 9496 1.1.1.2.2.2 bouyer 9497 1.1.1.2.2.2 bouyer Fixed a problem where a NULL pointer was being dereferenced in the 9498 1.1.1.2.2.2 bouyer interpreter code for the ASL Notify operator. 9499 1.1.1.2.2.2 bouyer 9500 1.1.1.2.2.2 bouyer Fixed a problem where the use of the ASL Revision operator 9501 1.1.1.2.2.2 bouyer returned an error. This operator now returns the current version 9502 1.1.1.2.2.2 bouyer of the ACPI CA core subsystem. 9503 1.1.1.2.2.2 bouyer 9504 1.1.1.2.2.2 bouyer Fixed a problem where objects passed as control method parameters 9505 1.1.1.2.2.2 bouyer to AcpiEvaluateObject were always deleted at method termination. 9506 1.1.1.2.2.2 bouyer However, these objects may end up being stored into the namespace 9507 1.1.1.2.2.2 bouyer by the called method. The object reference count mechanism was 9508 1.1.1.2.2.2 bouyer applied to these objects instead of a force delete. 9509 1.1.1.2.2.2 bouyer 9510 1.1.1.2.2.2 bouyer Fixed a problem where static strings or buffers (contained in the 9511 1.1.1.2.2.2 bouyer AML code) that are declared as package elements within the ASL 9512 1.1.1.2.2.2 bouyer code could cause a fault because the interpreter would attempt to 9513 1.1.1.2.2.2 bouyer delete them. These objects are now marked with the "static 9514 1.1.1.2.2.2 bouyer object" flag to prevent any attempt to delete them. 9515 1.1.1.2.2.2 bouyer 9516 1.1.1.2.2.2 bouyer Implemented an interpreter optimization to use operands directly 9517 1.1.1.2.2.2 bouyer from the state object instead of extracting the operands to local 9518 1.1.1.2.2.2 bouyer variables. This reduces stack use and code size, and improves 9519 1.1.1.2.2.2 bouyer performance. 9520 1.1.1.2.2.2 bouyer 9521 1.1.1.2.2.2 bouyer The module exxface.c was eliminated as it was an unnecessary extra 9522 1.1.1.2.2.2 bouyer layer of code. 9523 1.1.1.2.2.2 bouyer 9524 1.1.1.2.2.2 bouyer Current core subsystem library code sizes are shown below. These 9525 1.1.1.2.2.2 bouyer are the code and data sizes for the acpica.lib produced by the 9526 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 compiler, and these values do not include 9527 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code 9528 1.1.1.2.2.2 bouyer includes the full debug trace mechanism -- leading to a much 9529 1.1.1.2.2.2 bouyer larger code and data size. Note that these values will vary 9530 1.1.1.2.2.2 bouyer depending on the efficiency of the compiler and the compiler 9531 1.1.1.2.2.2 bouyer options used during generation. 9532 1.1.1.2.2.2 bouyer 9533 1.1.1.2.2.2 bouyer Non-Debug Version: 65K Code, 5K Data, 70K Total 9534 1.1.1.2.2.2 bouyer (Previously 69K) Debug Version: 138K Code, 58K Data, 196K 9535 1.1.1.2.2.2 bouyer Total (Previously 195K) 9536 1.1.1.2.2.2 bouyer 9537 1.1.1.2.2.2 bouyer Linux: 9538 1.1.1.2.2.2 bouyer 9539 1.1.1.2.2.2 bouyer Support for ACPI 2.0 64-bit integers has been added.

The implicit function return value (not the 9556 1.1.1.2.2.2 bouyer explicit store operands) was returning the remainder instead of 9557 1.1.1.2.2.2 bouyer the quotient. This was a longstanding bug and it fixes several 9558 1.1.1.2.2.2 bouyer known outstanding issues on various platforms. 9559 1.1.1.2.2.2 bouyer 9560 1.1.1.2.2.2 bouyer The ACPI_DEBUG_PRINT and function trace entry/exit macros have 9561 1.1.1.2.2.2 bouyer been further optimized for size. There are 700 invocations of the 9562 1.1.1.2.2.2 bouyer DEBUG_PRINT macro alone, so each optimization reduces the size of 9563 1.1.1.2.2.2 bouyer the debug version of the subsystem significantly. 9564 1.1.1.2.2.2 bouyer 9565 1.1.1.2.2.2 bouyer A stack trace mechanism has been implemented. The maximum stack 9566 1.1.1.2.2.2 bouyer usage is about 2K on 32-bit platforms. The debugger command "stat 9567 1.1.1.2.2.2 bouyer stack" will display the current maximum stack usage. 9568 1.1.1.2.2.2 bouyer 9569 1.1.1.2.2.2 bouyer All public symbols and global variables within the subsystem are 9570 1.1.1.2.2.2 bouyer now prefixed with the string "Acpi". This keeps all of the 9571 1.1.1.2.2.2 bouyer symbols grouped together in a kernel map, and avoids conflicts 9572 1.1.1.2.2.2 bouyer with other kernel subsystems. 9573 1.1.1.2.2.2 bouyer 9574 1.1.1.2.2.2 bouyer Most of the internal fixed lookup tables have been moved into the 9575 1.1.1.2.2.2 bouyer code segment via the const operator. 9576 1.1.1.2.2.2 bouyer 9577 1.1.1.2.2.2 bouyer Several enhancements have been made to the interpreter to both 9578 1.1.1.2.2.2 bouyer reduce the code size and improve performance. 9579 1.1.1.2.2.2 bouyer 9580 1.1.1.2.2.2 bouyer Current core subsystem library code sizes are shown below. These 9581 1.1.1.2.2.2 bouyer are the code and data sizes for the acpica.lib produced by the 9582 1.1.1.2.2.2 bouyer Microsoft Visual C++ 6.0 compiler, and these values do not include 9583 1.1.1.2.2.2 bouyer any ACPI driver or OSPM code. The debug version of the code 9584 1.1.1.2.2.2 bouyer includes the full debug trace mechanism which contains over 700 9585 1.1.1.2.2.2 bouyer invocations of the DEBUG_PRINT macro, 500 function entry macro 9586 1.1.1.2.2.2 bouyer invocations, and over 900 function exit macro invocations -- 9587 1.1.1.2.2.2 bouyer leading to a much larger code and data size. Note that these 9588 1.1.1.2.2.2 bouyer values will vary depending on the efficiency of the compiler and 9589 1.1.1.2.2.2 bouyer the compiler options used during generation. 9590 1.1.1.2.2.2 bouyer 9591 1.1.1.2.2.2 bouyer Non-Debug Version: 64K Code, 5K Data, 69K Total 9592 1.1.1.2.2.2 bouyer Debug Version: 137K Code, 58K Data, 195K Total 9593 1.1.1.2.2.2 bouyer 9594 1.1.1.2.2.2 bouyer Linux: 9595 1.1.1.2.2.2 bouyer 9596 1.1.1.2.2.2 bouyer Implemented wbinvd() macro, pending a kernel-wide definition. 9597 1.1.1.2.2.2 bouyer 9598 1.1.1.2.2.2 bouyer Fixed /proc/acpi/event to handle poll() and short reads. 9599 1.1.1.2.2.2 bouyer 9600 1.1.1.2.2.2 bouyer ASL Compiler, version X2026: 9601 1.1.1.2.2.2 bouyer 9602 1.1.1.2.2.2 bouyer Fixed a problem introduced in the previous label where the AML 9603 1.1.1.2.2.2 bouyer 9604 1.1.1.2.2.2 bouyer code emitted for package objects produced packages with zero 9605 1.1.1.2.2.2 bouyer length. 9606 1.1.1.2.2.2 bouyer 9607 1.1.1.2.2.2 bouyer ---------------------------------------- 9608 1.1.1.2.2.2 bouyer Summary of changes for this label: 08_16_01 9609 1.1.1.2.2.2 bouyer 9610 1.1.1.2.2.2 bouyer ACPI CA Core Subsystem: 9611 1.1.1.2.2.2 bouyer 9612 1.1.1.2.2.2 bouyer The following ACPI 2.0 ASL operators have been implemented in the 9613 1.1.1.2.2.2 bouyer AML interpreter (These are already supported by the Intel ASL 9614 1.1.1.2.2.2 bouyer compiler): ToDecimalString, ToHexString, ToString, ToInteger, and 9615 1.1.1.2.2.2 bouyer ToBuffer. Support for 64-bit AML constants is implemented in the 9616 1.1.1.2.2.2 bouyer AML parser, debugger, and disassembler. 9617 1.1.1.2.2.2 bouyer 9618 1.1.1.2.2.2 bouyer The internal memory tracking mechanism (leak detection code) has 9619 1.1.1.2.2.2 bouyer been upgraded to reduce the memory overhead (a separate tracking 9620 1.1.1.2.2.2 bouyer block is no longer allocated for each memory allocation), and now 9621 1.1.1.2.2.2 bouyer supports all of the internal object caches. 9622 1.1.1.2.2.2 bouyer 9623 1.1.1.2.2.2 bouyer The data structures and code for the internal object caches have 9624 1.1.1.2.2.2 bouyer been coelesced and optimized so that there is a single cache and 9625 1.1.1.2.2.2 bouyer memory list data structure and a single group of functions that 9626 1.1.1.2.2.2 bouyer implement generic cache management. This has reduced the code 9627 1.1.1.2.2.2 bouyer size in both the debug and release versions of the subsystem. 9628 1.1.1.2.2.2 bouyer 9629 1.1.1.2.2.2 bouyer The DEBUG_PRINT macro(s) have been optimized for size and replaced 9630 1.1.1.2.2.2 bouyer by ACPI_DEBUG_PRINT. The syntax for this macro is slightly 9631 1.1.1.2.2.2 bouyer different, because it generates a single call to an internal 9632 1.1.1.2.2.2 bouyer function. This results in a savings of about 90 bytes per 9633 1.1.1.2.2.2 bouyer invocation, resulting in an overall code and data savings of about 9634 1.1.1.2.2.2 bouyer 16% in the debug version of the subsystem. 9635 1.1.1.2.2.2 bouyer 9636 1.1.1.2.2.2 bouyer Linux: 9637 1.1.1.2.2.2 bouyer 9638 1.1.1.2.2.2 bouyer Fixed C3 disk corruption problems and re-enabled C3 on supporting 9639 1.1.1.2.2.2 bouyer machines. 9640 1.1.1.2.2.2 bouyer 9641 1.1.1.2.2.2 bouyer Integrated low-level sleep code by Patrick Mochel. 9642 1.1.1.2.2.2 bouyer 9643 1.1.1.2.2.2 bouyer Further tweaked source code Linuxization. 9644 1.1.1.2.2.2 bouyer 9645 1.1.1.2.2.2 bouyer Other minor fixes. 9646 1.1.1.2.2.2 bouyer 9647 1.1.1.2.2.2 bouyer ASL Compiler: 9648 1.1.1.2.2.2 bouyer 9649 1.1.1.2.2.2 bouyer Support for ACPI 2.0 variable length packages is fixed/completed. 9650 1.1.1.2.2.2 bouyer 9651 1.1.1.2.2.2 bouyer Fixed a problem where the optional length parameter for the ACPI 9652 1.1.1.2.2.2 bouyer 2.0 ToString operator. 9653 1.1.1.2.2.2 bouyer 9654 1.1.1.2.2.2 bouyer Fixed multiple extraneous error messages when a syntax error is 9655 1.1.1.2.2.2 bouyer detected within the declaration line of a control method. 9656 1.1.1.2.2.2 bouyer 9657 1.1.1.2.2.2 bouyer ---------------------------------------- 9658 1.1.1.2.2.2 bouyer Summary of changes for this label: 07_17_01 9659 1.1.1.2.2.2 bouyer 9660 1.1.1.2.2.2 bouyer ACPI CA Core Subsystem: 9661 1.1.1.2.2.2 bouyer 9662 1.1.1.2.2.2 bouyer Added a new interface named AcpiGetFirmwareTable to obtain any 9663 1.1.1.2.2.2 bouyer ACPI table via the ACPI signature. The interface can be called at 9664 1.1.1.2.2.2 bouyer any time during kernel initialization, even before the kernel 9665 1.1.1.2.2.2 bouyer virtual memory manager is initialized and paging is enabled. This 9666 1.1.1.2.2.2 bouyer allows kernel subsystems to obtain ACPI tables very early, even 9667 1.1.1.2.2.2 bouyer before the ACPI CA subsystem is initialized. 9668 1.1.1.2.2.2 bouyer 9669 1.1.1.2.2.2 bouyer Fixed a problem where Fields defined with the AnyAcc attribute 9670 1.1.1.2.2.2 bouyer could be resolved to the incorrect address under the following 9671 1.1.1.2.2.2 bouyer conditions: 1) the field width is larger than 8 bits and 2) the 9672 1.1.1.2.2.2 bouyer parent operation region is not defined on a DWORD boundary. 9673 1.1.1.2.2.2 bouyer 9674 1.1.1.2.2.2 bouyer Fixed a problem where the interpreter is not being locked during 9675 1.1.1.2.2.2 bouyer namespace initialization (during execution of the _INI control 9676 1.1.1.2.2.2 bouyer methods), causing an error when an attempt is made to release it 9677 1.1.1.2.2.2 bouyer later. 9678 1.1.1.2.2.2 bouyer 9679 1.1.1.2.2.2 bouyer ACPI 2.0 support in the AML Interpreter has begun and will be 9680 1.1.1.2.2.2 bouyer ongoing throughout the rest of this year. In this label, The Mod 9681 1.1.1.2.2.2 bouyer operator is implemented. 9682 1.1.1.2.2.2 bouyer 9683 1.1.1.2.2.2 bouyer Added a new data type to contain full PCI addresses named 9684 1.1.1.2.2.2 bouyer ACPI_PCI_ID. This structure contains the PCI Segment, Bus, Device, 9685 1.1.1.2.2.2 bouyer and Function values. 9686 1.1.1.2.2.2 bouyer 9687 1.1.1.2.2.2 bouyer Linux: 9688 1.1.1.2.2.2 bouyer 9689 1.1.1.2.2.2 bouyer Enhanced the Linux version of the source code to change most 9690 1.1.1.2.2.2 bouyer capitalized ACPI type names to lowercase. For example, all 9691 1.1.1.2.2.2 bouyer instances of ACPI_STATUS are changed to acpi_status. This will 9692 1.1.1.2.2.2 bouyer result in a large diff, but the change is strictly cosmetic and 9693 1.1.1.2.2.2 bouyer aligns the CA code closer to the Linux coding standard. 9694 1.1.1.2.2.2 bouyer 9695 1.1.1.2.2.2 bouyer OSL Interfaces: 9696 1.1.1.2.2.2 bouyer 9697 1.1.1.2.2.2 bouyer The interfaces to the PCI configuration space have been changed to 9698 1.1.1.2.2.2 bouyer add the PCI Segment number and to split the single 32-bit combined 9699 1.1.1.2.2.2 bouyer DeviceFunction field into two 16-bit fields. This was 9700 1.1.1.2.2.2 bouyer accomplished by moving the four values that define an address in 9701 1.1.1.2.2.2 bouyer PCI configuration space (segment, bus, device, and function) to 9702 1.1.1.2.2.2 bouyer the new ACPI_PCI_ID structure. 9703 1.1.1.2.2.2 bouyer 9704 1.1.1.2.2.2 bouyer The changes to the PCI configuration space interfaces led to a 9705 1.1.1.2.2.2 bouyer reexamination of the complete set of address space access 9706 1.1.1.2.2.2 bouyer interfaces for PCI, I/O, and Memory. The previously existing 18 9707 1.1.1.2.2.2 bouyer interfaces have proven difficult to maintain (any small change 9708 1.1.1.2.2.2 bouyer must be propagated across at least 6 interfaces) and do not easily 9709 1.1.1.2.2.2 bouyer allow for future expansion to 64 bits if necessary. Also, on some 9710 1.1.1.2.2.2 bouyer systems, it would not be appropriate to demultiplex the access 9711 1.1.1.2.2.2 bouyer width (8, 16, 32,or 64) before calling the OSL if the 9712 1.1.1.2.2.2 bouyer corresponding native OS interfaces contain a similar access width 9713 1.1.1.2.2.2 bouyer parameter. For these reasons, the 18 address space interfaces 9714 1.1.1.2.2.2 bouyer have been replaced by these 6 new ones: 9715 1.1.1.2.2.2 bouyer 9716 1.1.1.2.2.2 bouyer AcpiOsReadPciConfiguration 9717 1.1.1.2.2.2 bouyer AcpiOsWritePciConfiguration 9718 1.1.1.2.2.2 bouyer AcpiOsReadMemory 9719 1.1.1.2.2.2 bouyer AcpiOsWriteMemory 9720 1.1.1.2.2.2 bouyer AcpiOsReadPort 9721 1.1.1.2.2.2 bouyer AcpiOsWritePort 9722 1.1.1.2.2.2 bouyer 9723 1.1.1.2.2.2 bouyer Added a new interface named AcpiOsGetRootPointer to allow the OSL 9724 1.1.1.2.2.2 bouyer to perform the platform and/or OS-specific actions necessary to 9725 1.1.1.2.2.2 bouyer obtain the ACPI RSDP table pointer. On IA-32 platforms, this 9726 1.1.1.2.2.2 bouyer interface will simply call down to the CA core to perform the low- 9727 1.1.1.2.2.2 bouyer memory search for the table. On IA-64, the RSDP is obtained from 9728 1.1.1.2.2.2 bouyer EFI. Migrating this interface to the OSL allows the CA core to 9729 1.1.1.2.2.2 bouyer 9730 1.1.1.2.2.2 bouyer remain OS and platform independent. 9731 1.1.1.2.2.2 bouyer 9732 1.1.1.2.2.2 bouyer Added a new interface named AcpiOsSignal to provide a generic 9733 1.1.1.2.2.2 bouyer "function code and pointer" interface for various miscellaneous 9734 1.1.1.2.2.2 bouyer signals and notifications that must be made to the host OS. The 9735 1.1.1.2.2.2 bouyer first such signals are intended to support the ASL Fatal and 9736 1.1.1.2.2.2 bouyer Breakpoint operators. In the latter case, the AcpiOsBreakpoint 9737 1.1.1.2.2.2 bouyer interface has been obsoleted. 9738 1.1.1.2.2.2 bouyer 9739 1.1.1.2.2.2 bouyer The definition of the AcpiFormatException interface has been 9740 1.1.1.2.2.2 bouyer changed to simplify its use. The caller no longer must supply a 9741 1.1.1.2.2.2 bouyer buffer to the call; A pointer to a const string is now returned 9742 1.1.1.2.2.2 bouyer directly. This allows the call to be easily used in printf 9743 1.1.1.2.2.2 bouyer statements, etc. since the caller does not have to manage a local 9744 1.1.1.2.2.2 bouyer buffer. 9745 1.1.1.2.2.2 bouyer 9746 1.1.1.2.2.2 bouyer 9747 1.1.1.2.2.2 bouyer ASL Compiler, Version X2025: 9748 1.1.1.2.2.2 bouyer 9749 1.1.1.2.2.2 bouyer The ACPI 2.0 Switch/Case/Default operators have been implemented 9750 1.1.1.2.2.2 bouyer and are fully functional. They will work with all ACPI 1.0 9751 1.1.1.2.2.2 bouyer interpreters, since the operators are simply translated to If/Else 9752 1.1.1.2.2.2 bouyer pairs. 9753 1.1.1.2.2.2 bouyer 9754 1.1.1.2.2.2 bouyer The ACPI 2.0 ElseIf operator is implemented and will also work 9755 1.1.1.2.2.2 bouyer with 1.0 interpreters, for the same reason. 9756 1.1.1.2.2.2 bouyer 9757 1.1.1.2.2.2 bouyer Implemented support for ACPI 2.0 variable-length packages. These 9758 1.1.1.2.2.2 bouyer packages have a separate opcode, and their size is determined by 9759 1.1.1.2.2.2 bouyer the interpreter at run-time. 9760 1.1.1.2.2.2 bouyer 9761 1.1.1.2.2.2 bouyer Documentation The ACPI CA Programmer Reference has been updated to 9762 1.1.1.2.2.2 bouyer reflect the new interfaces and changes to existing interfaces. 9763 1.1.1.2.2.2 bouyer 9764 1.1.1.2.2.2 bouyer ------------------------------------------ 9765 1.1.1.2.2.2 bouyer Summary of changes for this label: 06_15_01 9766 1.1.1.2.2.2 bouyer 9767 1.1.1.2.2.2 bouyer ACPI CA Core Subsystem: 9768 1.1.1.2.2.2 bouyer 9769 1.1.1.2.2.2 bouyer Fixed a problem where a DWORD-accessed field within a Buffer 9770 1.1.1.2.2.2 bouyer object would get its byte address inadvertently rounded down to 9771 1.1.1.2.2.2 bouyer the nearest DWORD.

All files within the 10502 1.1.1.2.2.2 bouyer interpreter have been renamed as well as most header files. This 10503 1.1.1.2.2.2 bouyer was done to prevent collisions with existing files in the host 10504 1.1.1.2.2.2 bouyer OSs -- filenames such as "config.h" and "global.h" seem to be 10505 1.1.1.2.2.2 bouyer quite common.

In order to obtain approval to get 10539 1.1.1.2.2.2 bouyer the ACPI CA subsystem into the Linux kernel, we've had to make 10540 1.1.1.2.2.2 bouyer quite a few changes to the base subsystem that will affect all 10541 1.1.1.2.2.2 bouyer users (all the changes are generic and OS- independent). The 10542 1.1.1.2.2.2 bouyer effects of these global changes have been somewhat far reaching. 10543 1.1.1.2.2.2 bouyer Files have been merged and/or renamed and interfaces have been 10544 1.1.1.2.2.2 bouyer renamed. The major changes are described below. 10545 1.1.1.2.2.2 bouyer 10546 1.1.1.2.2.2 bouyer Osd* interfaces renamed to AcpiOs* to eliminate namespace 10547 1.1.1.2.2.2 bouyer pollution/confusion within our target kernels. All OSD 10548 1.1.1.2.2.2 bouyer interfaces must be modified to match the new naming convention. 10549 1.1.1.2.2.2 bouyer 10550 1.1.1.2.2.2 bouyer Files merged across the subsystem. A number of the smaller source 10551 1.1.1.2.2.2 bouyer and header files have been merged to reduce the file count and 10552 1.1.1.2.2.2 bouyer increase the density of the existing files. There are too many 10553 1.1.1.2.2.2 bouyer to list here. In general, makefiles that call out individual 10554 1.1.1.2.2.2 bouyer files will require rebuilding. 10555 1.1.1.2.2.2 bouyer 10556 1.1.1.2.2.2 bouyer Interpreter files renamed. All interpreter files now have the 10557 1.1.1.2.2.2 bouyer prefix am* instead of ie* and is*. 10558 1.1.1.2.2.2 bouyer 10559 1.1.1.2.2.2 bouyer Header files renamed: The acapi.h file is now acpixf.h. The 10560 1.1.1.2.2.2 bouyer acpiosd.h file is now acpiosxf.h. We are removing references to 10561 1.1.1.2.2.2 bouyer the acronym "API" since it is somewhat windowsy. The new name is 10562 1.1.1.2.2.2 bouyer "external interface" or xface or xf in the filenames.j 10563 1.1.1.2.2.2 bouyer 10564 1.1.1.2.2.2 bouyer 10565 1.1.1.2.2.2 bouyer All manifest constants have been forced to upper case (some were 10566 1.1.1.2.2.2 bouyer mixed case.) Also, the string "ACPI_" has been prepended to many 10567 1.1.1.2.2.2 bouyer (not all) of the constants, typedefs, and structs. 10568 1.1.1.2.2.2 bouyer 10569 1.1.1.2.2.2 bouyer The globals "DebugLevel" and "DebugLayer" have been renamed 10570 1.1.1.2.2.2 bouyer "AcpiDbgLevel" and "AcpiDbgLayer" respectively. 10571 1.1.1.2.2.2 bouyer 10572 1.1.1.2.2.2 bouyer All other globals within the subsystem are now prefixed with 10573 1.1.1.2.2.2 bouyer "AcpiGbl_" Internal procedures within the subsystem are now 10574 1.1.1.2.2.2 bouyer prefixed with "Acpi" (with only a few exceptions). The original 10575 1.1.1.2.2.2 bouyer two-letter abbreviation for the subcomponent remains after "Acpi" 10576 1.1.1.2.2.2 bouyer - for example, CmCallocate became AcpiCmCallocate. 10577 1.1.1.2.2.2 bouyer 10578 1.1.1.2.2.2 bouyer Added a source code translation/conversion utility. Used to 10579 1.1.1.2.2.2 bouyer generate the Linux source code, it can be modified to generate 10580 1.1.1.2.2.2 bouyer other types of source as well. Can also be used to cleanup 10581 1.1.1.2.2.2 bouyer existing source by removing extraneous spaces and blank lines. 10582 1.1.1.2.2.2 bouyer Found in tools/acpisrc/* 10583 1.1.1.2.2.2 bouyer 10584 1.1.1.2.2.2 bouyer OsdUnMapMemory was renamed to OsdUnmapMemory and then 10585 1.1.1.2.2.2 bouyer AcpiOsUnmapMemory. (UnMap became Unmap). 10586 1.1.1.2.2.2 bouyer 10587 1.1.1.2.2.2 bouyer A "MaxUnits" parameter has been added to AcpiOsCreateSemaphore. 10588 1.1.1.2.2.2 bouyer When set to one, this indicates that the caller wants to use the 10589 1.1.1.2.2.2 bouyer 10590 1.1.1.2.2.2 bouyer semaphore as a mutex, not a counting semaphore. ACPI CA uses 10591 1.1.1.2.2.2 bouyer both types. However, implementers of this call may want to use 10592 1.1.1.2.2.2 bouyer different OS primitives depending on the type of semaphore 10593 1.1.1.2.2.2 bouyer requested. For example, some operating systems provide separate 10594 1.1.1.2.2.2 bouyer 10595 1.1.1.2.2.2 bouyer "mutex" and "semaphore" interfaces - where the mutex interface is 10596 1.1.1.2.2.2 bouyer much faster because it doesn't have all the overhead of a full 10597 1.1.1.2.2.2 bouyer semaphore implementation. 10598 1.1.1.2.2.2 bouyer 10599 1.1.1.2.2.2 bouyer Fixed a deadlock problem where a method that accesses the PCI 10600 1.1.1.2.2.2 bouyer address space can block forever if it is the first access to the 10601 1.1.1.2.2.2 bouyer space. 10602 1.1.1.2.2.2 bouyer 10603 1.1.1.2.2.2 bouyer ------------------------------------------- 10604 1.1.1.2.2.2 bouyer Summary of changes for this label: 06_02_00 10605 1.1.1.2.2.2 bouyer 10606 1.1.1.2.2.2 bouyer Support for environments that cannot handle unaligned data 10607 1.1.1.2.2.2 bouyer accesses (e.g. firmware and OS environments devoid of alignment 10608 1.1.1.2.2.2 bouyer handler technology namely SAL/EFI and the IA-64 Linux kernel) has 10609 1.1.1.2.2.2 bouyer been added (via configurable macros) in these three areas: - 10610 1.1.1.2.2.2 bouyer Transfer of data from the raw AML byte stream is done via byte 10611 1.1.1.2.2.2 bouyer moves instead of word/dword/qword moves. - External objects are 10612 1.1.1.2.2.2 bouyer aligned within the user buffer, including package elements (sub- 10613 1.1.1.2.2.2 bouyer objects). - Conversion of name strings to UINT32 Acpi Names is now 10614 1.1.1.2.2.2 bouyer done byte-wise. 10615 1.1.1.2.2.2 bouyer 10616 1.1.1.2.2.2 bouyer The Store operator was modified to mimic Microsoft's 10617 1.1.1.2.2.2 bouyer implementation when storing to a Buffer Field. 10618 1.1.1.2.2.2 bouyer 10619 1.1.1.2.2.2 bouyer Added a check of the BM_STS bit before entering C3. 10620 1.1.1.2.2.2 bouyer 10621 1.1.1.2.2.2 bouyer The methods subdirectory has been obsoleted and removed. A new 10622 1.1.1.2.2.2 bouyer file, cmeval.c subsumes the functionality. 10623 1.1.1.2.2.2 bouyer 10624 1.1.1.2.2.2 bouyer A 16-bit (DOS) version of AcpiExec has been developed. The 10625 1.1.1.2.2.2 bouyer makefile is under the acpiexec directory. 10626
