Summary of changes for version 20101209: + +This release is available at www.acpica.org/downloads + +1) ACPI CA Core Subsystem: + +Completed the major overhaul of the GPE support code that was begun in July +2010. Major features include: removal of _PRW execution in ACPICA (host +executes _PRWs anyway), cleanup of "wake" GPE interfaces and processing, +changes to existing interfaces, simplification of GPE handler operation, and +a handful of new interfaces: + + AcpiUpdateAllGpes + AcpiFinishGpe + AcpiSetupGpeForWake + AcpiSetGpeWakeMask + One new file, evxfgpe.c to consolidate all external GPE interfaces. + +See the ACPICA Programmer Reference for full details and programming +information. See the new section 4.4 "General Purpose Event (GPE) Support" +for a full overview, and section 8.7 "ACPI General Purpose Event Management" +for programming details. ACPICA BZ 858,870,877. Matthew Garrett, Lin Ming, +Bob Moore, Rafael Wysocki. + +Implemented a new GPE feature for Windows compatibility, the "Implicit Wake +GPE Notify". This feature will automatically issue a Notify(2) on a device +when a Wake GPE is received if there is no corresponding GPE method or +handler. ACPICA BZ 870. + +Fixed a problem with the Scope() operator during table parse and load phase. +During load phase (table load or method execution), the scope operator should +not enter the target into the namespace. Instead, it should open a new scope +at the target location. Linux BZ 19462, ACPICA BZ 882. + +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: 89.8K Code, 18.9K Data, 108.7K Total + Debug Version: 166.6K Code, 52.1K Data, 218.7K Total + Current Release: + Non-Debug Version: 89.9K Code, 19.0K Data, 108.9K Total + Debug Version: 166.3K Code, 52.1K Data, 218.4K Total + +2) iASL Compiler/Disassembler and Tools: + +iASL: Relax the alphanumeric restriction on _CID strings. These strings are +"bus-specific" per the ACPI specification, and therefore any characters are +acceptable. The only checks that can be performed are for a null string and +perhaps for a leading asterisk. ACPICA BZ 886. + +iASL: Fixed a problem where a syntax error that caused a premature EOF +condition on the source file emitted a very confusing error message. The +premature EOF is now detected correctly. ACPICA BZ 891. + +Disassembler: Decode the AccessSize within a Generic Address Structure (byte +access, word access, etc.) Note, this field does not allow arbitrary bit +access, the size is encoded as 1=byte, 2=word, 3=dword, and 4=qword. + +New: AcpiNames utility - Example namespace dump utility. Shows an example of +ACPICA configuration for a minimal namespace dump utility. Uses table and +namespace managers, but no AML interpreter. Does not add any functionality +over AcpiExec, it is a subset of AcpiExec. The purpose is to show how to +partition and configure ACPICA. ACPICA BZ 883. + +AML Debugger: Increased the debugger buffer size for method return objects. +Was 4K, increased to 16K. Also enhanced error messages for debugger method +execution, including the buffer overflow case. + +---------------------------------------- 13 October 2010.
