Summary of changes for version 20090903: +13 October 2009. Summary of changes for version 20091013: This release is available at www.acpica.org/downloads 1) ACPI CA Core Subsystem: +Fixed a problem where an Operation Region _REG method could be executed more +than once. If a custom address space handler is installed by the host before +the "initialize operation regions" phase of the ACPICA initialization, any +_REG methods for that address space could be executed twice. This change +fixes the problem. ACPICA BZ 427. Lin Ming. + +Fixed a possible memory leak for the Scope() ASL operator. When the exact +invocation of "Scope(\)" is executed (change scope to root), one internal +operand object was leaked. Lin Ming. + +Implemented a run-time repair for the _MAT predefined method. If the _MAT +return value is defined as a Field object in the AML, and the field +size is less than or equal to the default width of an integer (32 or 64),_MAT +can incorrectly return an Integer instead of a Buffer. ACPICA now +automatically repairs this problem. ACPICA BZ 810. + +Implemented a run-time repair for the _BIF and _BIX predefined methods. The +"OEM Information" field is often incorrectly returned as an Integer with +value zero if the field is not supported by the platform. This is due to an +ambiguity in the ACPI specification. The field should always be a string. +ACPICA now automatically repairs this problem by returning a NULL string +within the returned Package. ACPICA BZ 807. + +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: 85.6K Code, 18.0K Data, 103.6K Total + Debug Version: 161.7K Code, 50.9K Data, 212.6K Total + Current Release: + Non-Debug Version: 85.8K Code, 18.0K Data, 103.8K Total + Debug Version: 161.8K Code, 50.6K Data, 212.4K Total + +2) iASL Compiler/Disassembler and Tools: + +Disassembler: Fixed a problem where references to external symbols that +contained one or more parent-prefixes (carats) were not handled correctly, +possibly causing a fault. ACPICA BZ 806. Lin Ming. + +Disassembler: Restructured the code so that all functions that handle +external symbols are in a single module. One new file is added, +common/dmextern.c. + +AML Debugger: Added a max count argument for the Batch command (which +executes multiple predefined methods within the namespace.) + +iASL: Updated the compiler documentation (User Reference.) Available at +http://www.acpica.org/documentation/. ACPICA BZ 750. + +AcpiXtract: Updated for Lint and other formatting changes.
