Summary of changes for version 20090730: + +This release is available at www.acpica.org/downloads + +The ACPI 4.0 implementation for ACPICA is complete with this release. + +1) ACPI CA Core Subsystem: + +ACPI 4.0: Added header file support for all new and changed ACPI tables. +Completely new tables are: IBFT, IVRS, MSCT, and WAET. Tables that are new +for ACPI 4.0, but have previously been supported in ACPICA are: CPEP, BERT, +EINJ, ERST, and HEST. Other newly supported tables are: UEFI and WDAT. There +have been some ACPI 4.0 changes to other existing tables. Split the large +actbl1.h header into the existing actbl2.h header. ACPICA BZ 774. + +ACPI 4.0: Implemented predefined name validation for all new names. There are +31 new names in ACPI 4.0. The predefined validation module was split into two +files. The new file is namespace/nsrepair.c. ACPICA BZ 770. + +Implemented support for so-called "module-level executable code". This is +executable AML code that exists outside of any control method and is intended +to be executed at table load time. Although illegal since ACPI 2.0, this type +of code still exists and is apparently still being created. Blocks of this +code are now detected and executed as intended. Currently, the code blocks +must exist under either an If, Else, or While construct; these are the +typical cases seen in the field. ACPICA BZ 762. Lin Ming. + +Implemented an automatic dynamic repair for predefined names that return +nested Package objects. This applies to predefined names that are defined to +return a variable-length Package of sub-packages. If the number of sub- +packages is one, BIOS code is occasionally seen that creates a simple single +package with no sub-packages. This code attempts to fix the problem by +wrapping a new package object around the existing package. These methods can +be repaired: _ALR, _CSD, _HPX, _MLS, _PRT, _PSS, _TRT, and _TSS. ACPICA BZ +790. + +Fixed a regression introduced in 20090625 for the AcpiGetDevices interface. +The _HID/_CID matching was broken and no longer matched IDs correctly. ACPICA +BZ 793. + +Fixed a problem with AcpiReset where the reset would silently fail if the +register was one of the protected I/O ports. AcpiReset now bypasses the port +validation mechanism. This may eventually be driven into the AcpiRead/Write +interfaces. + +Fixed a regression related to the recent update of the AcpiRead/Write +interfaces. A sleep/suspend could fail if the optional PM2 Control register +does not exist during an attempt to write the Bus Master Arbitration bit. +(However, some hosts already delete the code that writes this bit, and the +code may in fact be obsolete at this date.) ACPICA BZ 799. + +Fixed a problem where AcpiTerminate could fault if inadvertently called twice +in succession. ACPICA BZ 795. + +Example Code and Data Size: These are the sizes for the OS-independent +acpica.lib produced by the Microsoft Visual C++ 6.0 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: 84.7K Code, 17.8K Data, 102.5K Total + Debug Version: 160.5K Code, 50.6K Data, 211.1K Total + Current Release: + Non-Debug Version: 85.5K Code, 18.0K Data, 103.5K Total + Debug Version: 161.6K Code, 50.9K Data, 212.5K Total + +2) iASL Compiler/Disassembler and Tools: + +ACPI 4.0: Implemented disassembler support for all new ACPI tables and +changes to existing tables.
