Summary of changes for version 20091214: + +This release is available at www.acpica.org/downloads + +1) ACPI CA Core Subsystem: + +Enhanced automatic data type conversions for predefined name repairs. This +change expands the automatic repairs/conversions for predefined name return +values to make Integers, Strings, and Buffers fully interchangeable. Also, a +Buffer can be converted to a Package of Integers if necessary. The nsrepair.c +module was completely restructured. Lin Ming, Bob Moore. + +Implemented automatic removal of null package elements during predefined name +repairs. This change will automatically remove embedded and trailing NULL +package elements from returned package objects that are defined to contain a +variable number of sub-packages. The driver is then presented with a package +with no null elements to deal with. ACPICA BZ 819. + +Implemented a repair for the predefined _FDE and _GTM names. The expected +return value for both names is a Buffer of 5 DWORDs. This repair fixes two +possible problems (both seen in the field), where a package of integers is +returned, or a buffer of BYTEs is returned. With assistance from Jung-uk Kim. + +Implemented additional module-level code support. This change will properly +execute module-level code that is not at the root of the namespace (under a +Device object, etc.). Now executes the code within the current scope instead +of the root. ACPICA BZ 762. Lin Ming. + +Fixed possible mutex acquisition errors when running _REG methods. Fixes a +problem where mutex errors can occur when running a _REG method that is in +the same scope as a method-defined operation region or an operation region +under a module-level IF block. This type of code is rare, so the problem has +not been seen before. ACPICA BZ 826. Lin Ming, Bob Moore. + +Fixed a possible memory leak during module-level code execution. An object +could be leaked for each block of executed module-level code if the +interpreter slack mode is enabled This change deletes any implicitly returned +object from the module-level code block. Lin Ming. + +Removed messages for successful predefined repair(s). The repair mechanism +was considered too wordy. Now, messages are only unconditionally emitted if +the return object cannot be repaired. Existing messages for successful +repairs were converted to ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827. + +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: 86.6K Code, 18.2K Data, 104.8K Total + Debug Version: 162.7K Code, 50.8K Data, 213.5K Total + Current Release: + Non-Debug Version: 87.0K Code, 18.0K Data, 105.0K Total + Debug Version: 163.4K Code, 50.8K Data, 214.2K Total + +2) iASL Compiler/Disassembler and Tools: + +iASL: Fixed a regression introduced in 20091112 where intermediate .SRC files +were no longer automatically removed at the termination of the compile. + +acpiexec: Implemented the -f option to specify default region fill value. +This option specifies the value used to initialize buffers that simulate +operation regions. Default value is zero. Useful for debugging problems that +depend on a specific initial value for a region or field. + +---------------------------------------- 12 November 2009.
