----------------------------------------
09 December 2010. 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.

* Note: History of _PRW support in ACPICA

*
* As of 10/2010, the _PRW method execution has been removed since it is
* actually unnecessary. The host OS must in fact execute all _PRW methods
* in order to identify the device/power-resource dependencies. We now put
* the onus on the host OS to identify the wake GPEs as part of this process
* and to inform ACPICA of these GPEs via the AcpiSetupGpeForWake interface. This
* not only reduces the complexity of the ACPICA initialization code, but in
