Summary of changes for version 20110527: +20 March 2012. Summary of changes for version 20120320: + +This release is available at www.acpica.org/downloads. +The ACPI 5.0 specification is available at www.acpi.info. + +1) ACPICA Core Subsystem: + +Enhanced the sleep/wake interfaces to optionally execute the _GTS method +(Going To Sleep) and the _BFS method (Back From Sleep). Windows apparently +does not execute these methods, and therefore these methods are often +untested. It has been seen on some systems where the execution of these +methods causes errors and also prevents the machine from entering S5. It is +therefore suggested that host operating systems do not execute these methods +by default. In the future, perhaps these methods can be optionally executed +based on the age of the system and/or what is the newest version of Windows +that the BIOS asks for via _OSI. Changed interfaces: AcpiEnterSleepState and +AcpileaveSleepStatePrep. See the ACPICA reference and Linux BZ 13041. Lin +Ming. + +Fixed a problem where the length of the local/common FADT was set too early. +The local FADT table length cannot be set to the common length until the +original length has been examined. There is code that checks the table length +and sets various fields appropriately. This can affect older machines with +early FADT versions. For example, this can cause inadvertent writes to the +CST_CNT register. Julian Anastasov. + +Fixed a mapping issue related to a physical table override. Use the deferred +mapping mechanism for tables loaded via the physical override OSL interface. +This allows for early mapping before the virtual memory manager is available. +Thomas Renninger, Bob Moore. + +Enhanced the automatic return-object repair code: Repair a common problem with +predefined methods that are defined to return a variable-length Package of +sub-objects. If there is only one sub-object, some BIOS ASL code mistakenly +simply returns the single object instead of a Package with one sub-object. +This new support will repair this error by wrapping a Package object around +the original object, creating the correct and expected Package with one sub- +object. Names that can be repaired in this manner include: _ALR, _CSD, _HPX, +_MLS, _PLD, _PRT, _PSS, _TRT, _TSS, _BCL, _DOD, _FIX, and _Sx. ACPICA BZ 939. + +Changed the exception code returned for invalid ACPI paths passed as +parameters to external interfaces such as AcpiEvaluateObject. Was +AE_BAD_PARAMETER, now is the more sensible AE_BAD_PATHNAME. + +Example Code and Data Size: These are the sizes for the OS-independent +acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug +version of the code includes the debug output trace mechanism and has a much +larger code and data size. + + Previous Release: + Non-Debug Version: 93.0K Code, 25.0K Data, 118.0K Total + Debug Version: 172.5K Code, 73.2K Data, 245.7K Total + Current Release: + Non-Debug Version: 92.9K Code, 25.0K Data, 117.9K Total + Debug Version: 172.5K Code, 73.2K Data, 245.7K Total + + +2) iASL Compiler/Disassembler and Tools: + +iASL: Added the infrastructure and initial implementation of a integrated C- +like preprocessor. This will simplify BIOS development process by eliminating +the need for a separate preprocessing step during builds. On Windows, it also +eliminates the need to install a separate C compiler. ACPICA BZ 761. Some +features including full #define() macro support are still under development. +These preprocessor directives are supported: + #define + #elif + #else + #endif + #error + #if + #ifdef + #ifndef + #include + #pragma message + #undef + #warning +In addition, these new command line options are supported: + -D <symbol> Define symbol for preprocessor use + -li Create preprocessed output file (*.i) + -P Preprocess only and create preprocessor output file (*.i) + +Table Compiler: Fixed a problem where the equals operator within an expression +did not work properly. + +Updated iASL to use the current versions of Bison/Flex. Updated the Windows +project file to invoke these tools from the standard location. ACPICA BZ 904. +Versions supported: + Flex for Windows: V2.5.4 + Bison for Windows: V2.4.1 + +---------------------------------------- +15 February 2012. Summary of changes for version 20120215: + +This release is available at www.acpica.org/downloads. +The ACPI 5.0 specification is available at www.acpi.info. + +1) ACPICA Core Subsystem: + +There have been some major changes to the sleep/wake support code, as +described below (a - e). + +a) The AcpiLeaveSleepState has been split into two interfaces, similar to +AcpiEnterSleepStatePrep and AcpiEnterSleepState. The new interface is +AcpiLeaveSleepStatePrep. This allows the host to perform actions between the +time the _BFS method is called and the _WAK method is called. NOTE: all hosts +must update their wake/resume code or else sleep/wake will not work properly. +Rafael Wysocki. + +b) In AcpiLeaveSleepState, now enable all runtime GPEs before calling the _WAK +method. Some machines require that the GPEs are enabled before the _WAK method +is executed. Thomas Renninger. + +c) In AcpiLeaveSleepState, now always clear the WAK_STS (wake status) bit. +Some BIOS code assumes that WAK_STS will be cleared on resume and use it to +determine whether the system is rebooting or resuming. Matthew Garrett. + +d) Move the invocations of _GTS (Going To Sleep) and _BFS (Back From Sleep) to +match the ACPI specification requirement. Rafael Wysocki. + +e) Implemented full support for the ACPI 5.0 SleepStatus and SleepControl +registers within the V5 FADT. This support adds two new files: +hardware/hwesleep.c implements the support for the new registers. Moved all +sleep/wake external interfaces to hardware/hwxfsleep.c. + + +Added a new OSL interface for ACPI table overrides, +AcpiOsPhysicalTableOverride. This interface allows the host to override a +table via a physical address, instead of the logical address required by +AcpiOsTableOverride. This simplifies the host implementation. Initial +implementation by Thomas Renninger. The ACPICA implementation creates a single +shared function for table overrides that attempts both a logical and a +physical override. + +Expanded the OSL memory read/write interfaces to 64-bit data +(AcpiOsReadMemory, AcpiOsWriteMemory.) This enables full 64-bit memory +transfer support for GAS register structures passed to AcpiRead and AcpiWrite. + +Implemented the ACPI_REDUCED_HARDWARE option to allow the creation of a custom +build of ACPICA that supports only the ACPI 5.0 reduced hardware (SoC) model. +See the ACPICA reference for details. ACPICA BZ 942. This option removes about +10% of the code and 5% of the static data, and the following hardware ACPI +features become unavailable: + PM Event and Control registers + SCI interrupt (and handler) + Fixed Events + General Purpose Events (GPEs) + Global Lock + ACPI PM timer + FACS table (Waking vectors and Global Lock) + +Updated the unix tarball directory structure to match the ACPICA git source +tree. This ensures that the generic unix makefiles work properly (in +generate/unix). Also updated the Linux makefiles to match. ACPICA BZ 867. + +Updated the return value of the _REV predefined method to integer value 5 to +reflect ACPI 5.0 support. + +Moved the external ACPI PM timer interface prototypes to the public acpixf.h +file where they belong. + +Example Code and Data Size: These are the sizes for the OS-independent +acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug +version of the code includes the debug output trace mechanism and has a much +larger code and data size. + + Previous Release: + Non-Debug Version: 92.8K Code, 24.9K Data, 117.7K Total + Debug Version: 171.7K Code, 72.9K Data, 244.5K Total + Current Release: + Non-Debug Version: 93.0K Code, 25.0K Data, 118.0K Total + Debug Version: 172.5K Code, 73.2K Data, 245.7K Total + + +2) iASL Compiler/Disassembler and Tools: + +Disassembler: Fixed a problem with the new ACPI 5.0 serial resource +descriptors (I2C, SPI, UART) where the resource produce/consumer bit was +incorrectly displayed. + +AcpiHelp: Add display of ACPI/PNP device IDs that are defined in the ACPI +specification. + +---------------------------------------- +11 January 2012. Summary of changes for version 20120111: + +This release is available at www.acpica.org/downloads. +The ACPI 5.0 specification is available at www.acpi.info. + +1) ACPICA Core Subsystem: + +Implemented a new mechanism to allow host device drivers to check for address +range conflicts with ACPI Operation Regions. Both SystemMemory and SystemIO +address spaces are supported. A new external interface, AcpiCheckAddressRange, +allows drivers to check an address range against the ACPI namespace. See the +ACPICA reference for additional details. Adds one new file, +utilities/utaddress.c. Lin Ming, Bob Moore. + +Fixed several issues with the ACPI 5.0 FADT support: Add the sleep Control and +Status registers, update the ACPI 5.0 flags, and update internal data +structures to handle an FADT larger than 256 bytes. The size of the ACPI 5.0 +FADT is 268 bytes. + +Updated all ACPICA copyrights and signons to 2012. Added the 2012 copyright to +all module headers and signons, including the standard Linux header. This +affects virtually every file in the ACPICA core subsystem, iASL compiler, and +all ACPICA utilities. + +Example Code and Data Size: These are the sizes for the OS-independent +acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug +version of the code includes the debug output trace mechanism and has a much +larger code and data size. + + Previous Release: + Non-Debug Version: 92.3K Code, 24.9K Data, 117.2K Total + Debug Version: 170.8K Code, 72.6K Data, 243.4K Total + Current Release: + Non-Debug Version: 92.8K Code, 24.9K Data, 117.7K Total + Debug Version: 171.7K Code, 72.9K Data, 244.5K Total + + +2) iASL Compiler/Disassembler and Tools: + +Disassembler: fixed a problem with the automatic resource tag generation +support. Fixes a problem where the resource tags are inadvertently not +constructed if the table being disassembled contains external references to +control methods. Moved the actual construction of the tags to after the final +namespace is constructed (after 2nd parse is invoked due to external control +method references.) ACPICA BZ 941. + +Table Compiler: Make all "generic" operators caseless. These are the operators +like UINT8, String, etc. Making these caseless improves ease-of-use. ACPICA BZ +934. + +---------------------------------------- +23 November 2011. Summary of changes for version 20111123: + +0) ACPI 5.0 Support: + +This release contains full support for the ACPI 5.0 specification, as +summarized below. + +Reduced Hardware Support: +------------------------- + +This support allows for ACPI systems without the usual ACPI hardware. This +support is enabled by a flag in the revision 5 FADT. If it is set, ACPICA will +not attempt to initialize or use any of the usual ACPI hardware. Note, when +this flag is set, all of the following ACPI hardware is assumed to be not +present and is not initialized or accessed: + + General Purpose Events (GPEs) + Fixed Events (PM1a/PM1b and PM Control) + Power Management Timer and Console Buttons (power/sleep) + Real-time Clock Alarm + Global Lock + System Control Interrupt (SCI) + The FACS is assumed to be non-existent + +ACPI Tables: +------------ + +All new tables and updates to existing tables are fully supported in the +ACPICA headers (for use by device drivers), the disassembler, and the iASL +Data Table Compiler. ACPI 5.0 defines these new tables: + + BGRT /* Boot Graphics Resource Table */ + DRTM /* Dynamic Root of Trust for Measurement table */ + FPDT /* Firmware Performance Data Table */ + GTDT /* Generic Timer Description Table */ + MPST /* Memory Power State Table */ + PCCT /* Platform Communications Channel Table */ + PMTT /* Platform Memory Topology Table */ + RASF /* RAS Feature table */ + +Operation Regions/SpaceIDs: +--------------------------- + +All new operation regions are fully supported by the iASL compiler, the +disassembler, and the ACPICA runtime code (for dispatch to region handlers.) +The new operation region Space IDs are: + + GeneralPurposeIo + GenericSerialBus + +Resource Descriptors: +--------------------- + +All new ASL resource descriptors are fully supported by the iASL compiler, the +ASL/AML disassembler, and the ACPICA runtime Resource Manager code (including +all new predefined resource tags). New descriptors are: + + FixedDma + GpioIo + GpioInt + I2cSerialBus + SpiSerialBus + UartSerialBus + +ASL/AML Operators, New and Modified: +------------------------------------ + +One new operator is added, the Connection operator, which is used to associate +a GeneralPurposeIo or GenericSerialBus resource descriptor with individual +field objects within an operation region. Several new protocols are associated +with the AccessAs operator. All are fully supported by the iASL compiler, +disassembler, and runtime ACPICA AML interpreter: + + Connection // Declare Field Connection attributes + AccessAs: AttribBytes (n) // Read/Write N-Bytes Protocol + AccessAs: AttribRawBytes (n) // Raw Read/Write N-Bytes Protocol + AccessAs: AttribRawProcessBytes (n) // Raw Process Call Protocol + RawDataBuffer // Data type for Vendor Data fields + +Predefined ASL/AML Objects: +--------------------------- + +All new predefined objects/control-methods are supported by the iASL compiler +and the ACPICA runtime validation/repair (arguments and return values.) New +predefined names include the following: + +Standard Predefined Names (Objects or Control Methods): + _AEI, _CLS, _CPC, _CWS, _DEP, + _DLM, _EVT, _GCP, _CRT, _GWS, + _HRV, _PRE, _PSE, _SRT, _SUB. + +Resource Tags (Names used to access individual fields within resource +descriptors): + _DBT, _DPL, _DRS, _END, _FLC, + _IOR, _LIN, _MOD, _PAR, _PHA, + _PIN, _PPI, _POL, _RXL, _SLV, + _SPE, _STB, _TXL, _VEN. + +ACPICA External Interfaces: +--------------------------- + +Several new interfaces have been defined for use by ACPI-related device +drivers and other host OS services: + +AcpiAcquireMutex and AcpiReleaseMutex: These interfaces allow the host OS to +acquire and release AML mutexes that are defined in the DSDT/SSDT tables +provided by the BIOS. They are intended to be used in conjunction with the +ACPI 5.0 _DLM (Device Lock Method) in order to provide transaction-level +mutual exclusion with the AML code/interpreter. + +AcpiGetEventResources: Returns the (formatted) resource descriptors as defined +by the ACPI 5.0 _AEI object (ACPI Event Information). This object provides +resource descriptors associated with hardware-reduced platform events, similar +to the AcpiGetCurrentResources interface. + +Operation Region Handlers: For General Purpose IO and Generic Serial Bus +operation regions, information about the Connection() object and any optional +length information is passed to the region handler within the Context +parameter. + +AcpiBufferToResource: This interface converts a raw AML buffer containing a +resource template or resource descriptor to the ACPI_RESOURCE internal format +suitable for use by device drivers. Can be used by an operation region handler +to convert the Connection() buffer object into a ACPI_RESOURCE. + +Miscellaneous/Tools/TestSuites: +------------------------------- + +Support for extended _HID names (Four alpha characters instead of three). +Support for ACPI 5.0 features in the AcpiExec and AcpiHelp utilities. +Support for ACPI 5.0 features in the ASLTS test suite. +Fully updated documentation (ACPICA and iASL reference documents.) + +ACPI Table Definition Language: +------------------------------- + +Support for this language was implemented and released as a subsystem of the +iASL compiler in 2010. (See the iASL compiler User Guide.) + + +Non-ACPI 5.0 changes for this release: +-------------------------------------- + +1) ACPICA Core Subsystem: + +Fix a problem with operation region declarations where a failure can occur if +the region name and an argument that evaluates to an object (such as the +region address) are in different namespace scopes. Lin Ming, ACPICA BZ 937. + +Do not abort an ACPI table load if an invalid space ID is found within. This +will be caught later if the offending method is executed. ACPICA BZ 925. + +Fixed an issue with the FFixedHW space ID where the ID was not always +recognized properly (Both ACPICA and iASL). ACPICA BZ 926. + +Fixed a problem with the 32-bit generation of the unix-specific OSL +(osunixxf.c). Lin Ming, ACPICA BZ 936. + +Several changes made to enable generation with the GCC 4.6 compiler. ACPICA BZ +935. + +New error messages: Unsupported I/O requests (not 8/16/32 bit), and Index/Bank +field registers out-of-range. + +2) iASL Compiler/Disassembler and Tools: + +iASL: Implemented the __PATH__ operator, which returns the full pathname of +the current source file. -This release is available at www.acpica.org/downloads +AcpiHelp: Automatically display expanded keyword information for all ASL +operators. + +Debugger: Add "Template" command to disassemble/dump resource template +buffers. + +Added a new master script to generate and execute the ASLTS test suite. +Automatically handles 32- and 64-bit generation. See tests/aslts.sh + +iASL: Fix problem with listing generation during processing of the Switch() +operator where AML listing was disabled until the entire Switch block was +completed. + +iASL: Improve support for semicolon statement terminators. Fix "invalid +character" message for some cases when the semicolon is used. Semicolons are +now allowed after every <Term> grammar element. ACPICA BZ 927. + +iASL: Fixed some possible aliasing warnings during generation. ACPICA BZ 923. + +Disassembler: Fix problem with disassembly of the DataTableRegion operator +where an inadvertent "Unhandled deferred opcode" message could be generated. + +3) Example Code and Data Size + +These are the sizes for the OS-independent acpica.lib produced by the +Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code +includes the debug output trace mechanism and has a much larger code and data +size. + + Previous Release: + Non-Debug Version: 90.2K Code, 23.9K Data, 114.1K Total + Debug Version: 165.6K Code, 68.4K Data, 234.0K Total + Current Release: + Non-Debug Version: 92.3K Code, 24.9K Data, 117.2K Total + Debug Version: 170.8K Code, 72.6K Data, 243.4K Total + +---------------------------------------- +22 September 2011. Summary of changes for version 20110922: + +0) ACPI 5.0 News: + +Support for ACPI 5.0 in ACPICA has been underway for several months and will +be released at the same time that ACPI 5.0 is officially released. + +The ACPI 5.0 specification is on track for release in the next few months. + +1) ACPICA Core Subsystem: + +Fixed a problem where the maximum sleep time for the Sleep() operator was +intended to be limited to two seconds, but was inadvertently limited to 20 +seconds instead. + +Linux and Unix makefiles: Added header file dependencies to ensure correct +generation of ACPICA core code and utilities. Also simplified the makefiles +considerably through the use of the vpath variable to specify search paths. +ACPICA BZ 924. + +2) iASL Compiler/Disassembler and Tools: + +iASL: Implemented support to check the access length for all fields created to +access named Resource Descriptor fields. For example, if a resource field is +defined to be two bits, a warning is issued if a CreateXxxxField() is used +with an incorrect bit length. This is implemented for all current resource +descriptor names. ACPICA BZ 930. + +Disassembler: Fixed a byte ordering problem with the output of 24-bit and 56- +bit integers. + +iASL: Fixed a couple of issues associated with variable-length package +objects. 1) properly handle constants like One, Ones, Zero -- do not make a +VAR_PACKAGE when these are used as a package length. 2) Allow the VAR_PACKAGE +opcode (in addition to PACKAGE) when validating object types for predefined +names. + +iASL: Emit statistics for all output files (instead of just the ASL input and +AML output). Includes listings, hex files, etc. + +iASL: Added -G option to the table compiler to allow the compilation of custom +ACPI tables. The only part of a table that is required is the standard 36-byte +ACPI header. + +AcpiXtract: Ported to the standard ACPICA environment (with ACPICA headers), +which also adds correct 64-bit support. Also, now all output filenames are +completely lower case. + +AcpiExec: Ignore any non-AML tables (tables other than DSDT or SSDT) when +loading table files. A warning is issued for any such tables. The only +exception is an FADT. This also fixes a possible fault when attempting to load +non-AML tables. ACPICA BZ 932. + +AcpiHelp: Added the AccessAs and Offset operators. Fixed a problem where a +missing table terminator could cause a fault when using the -p option. + +AcpiSrc: Fixed a possible divide-by-zero fault when generating file +statistics. + +3) Example Code and Data Size + +These are the sizes for the OS-independent acpica.lib produced by the +Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code +includes the debug output trace mechanism and has a much larger code and data +size. + + Previous Release (VC 9.0): + Non-Debug Version: 90.2K Code, 23.9K Data, 114.1K Total + Debug Version: 165.6K Code, 68.4K Data, 234.0K Total + Current Release (VC 9.0): + Non-Debug Version: 90.2K Code, 23.9K Data, 114.1K Total + Debug Version: 165.6K Code, 68.4K Data, 234.0K Total + + +---------------------------------------- +23 June 2011. Summary of changes for version 20110623: + +1) ACPI CA Core Subsystem: + +Updated the predefined name repair mechanism to not attempt repair of a _TSS +return object if a _PSS object is present. We can only sort the _TSS return +package if there is no _PSS within the same scope. This is because if _PSS is +present, the ACPI specification dictates that the _TSS Power Dissipation field +is to be ignored, and therefore some BIOSs leave garbage values in the _TSS +Power field(s). In this case, it is best to just return the _TSS package as- +is. Reported by, and fixed with assistance from Fenghua Yu. + +Added an option to globally disable the control method return value validation +and repair. This runtime option can be used to disable return value repair if +this is causing a problem on a particular machine. Also added an option to +AcpiExec (-dr) to set this disable flag. + +All makefiles and project files: Major changes to improve generation of ACPICA +tools. ACPICA BZ 912: + Reduce default optimization levels to improve compatibility + For Linux, add strict-aliasing=0 for gcc 4 + Cleanup and simplify use of command line defines + Cleanup multithread library support + Improve usage messages + +Linux-specific header: update handling of THREAD_ID and pthread. For the 32- +bit case, improve casting to eliminate possible warnings, especially with the +acpica tools. + +Example Code and Data Size: These are the sizes for the OS-independent +acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug +version of the code includes the debug output trace mechanism and has a much +larger code and data size. + + Previous Release (VC 9.0): + Non-Debug Version: 90.1K Code, 23.9K Data, 114.0K Total + Debug Version: 165.6K Code, 68.4K Data, 234.0K Total + Current Release (VC 9.0): + Non-Debug Version: 90.2K Code, 23.9K Data, 114.1K Total + Debug Version: 165.6K Code, 68.4K Data, 234.0K Total + +2) iASL Compiler/Disassembler and Tools: + +With this release, a new utility named "acpihelp" has been added to the ACPICA +package. This utility summarizes the ACPI specification chapters for the ASL +and AML languages. It generates under Linux/Unix as well as Windows, and +provides the following functionality: + Find/display ASL operator(s) -- with description and syntax. + Find/display ASL keyword(s) -- with exact spelling and descriptions. + Find/display ACPI predefined name(s) -- with description, number + of arguments, and the return value data type. + Find/display AML opcode name(s) -- with opcode, arguments, and grammar. + Decode/display AML opcode -- with opcode name, arguments, and grammar. + +Service Layers: Make multi-thread support configurable. Conditionally compile +the multi-thread support so that threading libraries will not be linked if not +necessary. The only tool that requires multi-thread support is AcpiExec. + +iASL: Update yyerrror/AslCompilerError for "const" errors. Newer versions of +Bison appear to want the interface to yyerror to be a const char * (or at +least this is a problem when generating iASL on some systems.) ACPICA BZ 923 +Pierre Lejeune. + +Tools: Fix for systems where O_BINARY is not defined. Only used for Windows +versions of the tools. + +---------------------------------------- +27 May 2011.
