+28 August 2014. Summary of changes for version 20140828:
+
+1) ACPICA kernel-resident subsystem:
+
+Fixed a problem related to the internal use of the Timer() operator where
+a 64-bit divide could cause an attempted link to a double-precision math
+library. This divide is not actually necessary, so the code was
+restructured to eliminate it. Lv Zheng.
+
+ACPI 5.1: Added support for the runtime validation of the _DSD package
+(similar to the iASL support).
+
+ACPI 5.1/Headers: Added support for the GICC affinity subtable to the
+SRAT table. Hanjun Guo <hanjun.guo@linaro.org>.
+
+Example Code and Data Size: These are the sizes for the OS-independent
+acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
+debug version of the code includes the debug output trace mechanism and
+has a much larger code and data size.
+
+ Current Release:
+ Non-Debug Version: 98.8K Code, 27.3K Data, 126.1K Total
+ Debug Version: 192.1K Code, 79.8K Data, 271.9K Total
+ Previous Release:
+ Non-Debug Version: 98.7K Code, 27.3K Data, 126.0K Total1
+ Debug Version: 192.0K Code, 79.7K Data, 271.7K Total
+
+2) iASL Compiler/Disassembler and Tools:
+
+AcpiExec: Fixed a problem on unix systems where the original terminal
+state was not always properly restored upon exit. Seen when using the -v
+option. ACPICA BZ 1104.
+
+iASL: Fixed a problem with the validation of the ranges/length within the
+Memory24 resource descriptor. There was a boundary condition when the
+range was equal to the (length -1) caused by the fact that these values
+are defined in 256-byte blocks, not bytes. ACPICA BZ 1098
+
+Disassembler: Fixed a problem with the GpioInt descriptor interrupt polarity
+flags. The flags are actually 2 bits, not 1, and the "ActiveBoth" keyword is
+now supported properly.
+
+ACPI 5.1: Added the GICC affinity subtable to the SRAT table. Supported
+in the disassembler, data table compiler, and table template generator.
+
+iASL: Added a requirement for Device() objects that one of either a _HID
+or _ADR must exist within the scope of a Device, as per the ACPI
+specification. Remove a similar requirement that was incorrectly in place
+for the _DSD object.
+
+iASL: Added error detection for illegal named references within control
+methods that would cause runtime failures. Now trapped as errors are: 1)
+References to objects within a non-parent control method. 2) Forward
+references (within a method) -- for control methods, AML interpreters use
+a one-pass parse of control methods. ACPICA BZ 1008.
+
+iASL: Added error checking for dependencies related to the _PSx power
+methods. ACPICA BZ 1029.
+1) For _PS0, one of these must exist within the same scope: _PS1, _PS2,
+_PS3.
+2) For _PS1, _PS2, and PS3: A _PS0 object must exist within the same
+scope.
+
+iASL and table compiler: Cleanup miscellaneous memory leaks by fully
+deploying the existing object and string caches and adding new caches for
+the table compiler.
+
+iASL: Split the huge parser source file into multiple subfiles to improve
+manageability. Generation now requires the M4 macro preprocessor, which
+is part of the Bison distribution on both unix and windows platforms.
+
+AcpiSrc: Fixed and removed all extraneous warnings generated during
+entire ACPICA source code scan and/or conversion.
+

+----------------------------------------
+
+24 July 2014. Summary of changes for version 20140724:
+
+The ACPI 5.1 specification has been released and is available at:
+http://uefi.org/specs/access
+
+
+0) ACPI 5.1 support in ACPICA:
+
+ACPI 5.1 is fully supported in ACPICA as of this release.
+
+New predefined names. Support includes iASL and runtime ACPICA
+validation.
+ _CCA (Cache Coherency Attribute).
+ _DSD (Device-Specific Data). David Box.
+
+Modifications to existing ACPI tables. Support includes headers, iASL
+Data Table compiler, disassembler, and the template generator.
+ FADT - New fields and flags. Graeme Gregory.
+ GTDT - One new subtable and new fields. Tomasz Nowicki.
+ MADT - Two new subtables. Tomasz Nowicki.
+ PCCT - One new subtable.
+
+Miscellaneous.
+ New notification type for System Resource Affinity change events.
+
+
+1) ACPICA kernel-resident subsystem:
+
+Fixed a regression introduced in 20140627 where a fault can happen during
+the deletion of Alias AML namespace objects. The problem affected both
+the core ACPICA and the ACPICA tools including iASL and AcpiExec.
+
+Implemented a new GPE public interface, AcpiMarkGpeForWake. Provides a
+simple mechanism to enable wake GPEs that have no associated handler or
+control method. Rafael Wysocki.
+
+Updated the AcpiEnableGpe interface to disallow the enable if there is no
+handler or control method associated with the particular GPE. This will
+help avoid meaningless GPEs and even GPE floods. Rafael Wysocki.
+
+Updated GPE handling and dispatch by disabling the GPE before clearing
+the status bit for edge-triggered GPEs. Lv Zheng.
+
+Added Timer() support to the AML Debug object. The current timer value is
+now displayed with each invocation of (Store to) the debug object to
+enable simple generation of execution times for AML code (method
+execution for example.) ACPICA BZ 1093.
+
+Example Code and Data Size: These are the sizes for the OS-independent
+acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The
+debug version of the code includes the debug output trace mechanism and
+has a much larger code and data size.
+
+ Current Release:
+ Non-Debug Version: 98.7K Code, 27.3K Data, 126.0K Total
+ Debug Version: 192.0K Code, 79.7K Data, 271.7K Total
+ Previous Release:
+ Non-Debug Version: 98.7K Code, 27.2K Data, 125.9K Total
+ Debug Version: 191.7K Code, 79.6K Data, 271.3K Total
+
+
+2) iASL Compiler/Disassembler and Tools:
+
+Fixed an issue with the recently added local printf implementation,
+concerning width/precision specifiers that could cause incorrect output.
+Lv Zheng. ACPICA BZ 1094.
+
+Disassembler: Added support to detect buffers that contain UUIDs and
+disassemble them to an invocation of the ToUUID operator. Also emit
+commented descriptions of known ACPI-related UUIDs.
+
+AcpiHelp: Added support to display known ACPI-related UUIDs. New option,
+-u. Adds three new files.
+
+iASL: Update table compiler and disassembler for DMAR table changes that
+were introduced in September 2013. With assistance by David Woodhouse.
