15 September 2010. Summary of changes for version 20100915:
This release is available at www.acpica.org/downloads
1) ACPI CA Core Subsystem:
Removed the AcpiOsDerivePciId OSL interface. The various host implementations of this function were not OS-dependent and are now obsolete and can be removed from all host OSLs. This function has been replaced by AcpiHwDerivePciId, which is now part of the ACPICA core code. AcpiHwDerivePciId has been implemented without recursion. Adds one new module, hwpci.c. ACPICA BZ 857.
Implemented a dynamic repair for _HID and _CID strings. The following problems are now repaired at runtime: 1) Remove a leading asterisk in the string, and 2) the entire string is uppercased. Both repairs are in accordance with the ACPI specification and will simplify host driver code. ACPICA BZ 871.
The ACPI_THREAD_ID type is no longer configurable, internally it is now always UINT64. This simplifies the ACPICA code, especially any printf output. UINT64 is the only common data type for all thread_id types across all operating systems. It is now up to the host OSL to cast the native thread_id type to UINT64 before returning the value to ACPICA (via AcpiOsGetThreadId). Lin Ming, Bob Moore.
Added the ACPI_INLINE type to enhance the ACPICA configuration. The "inline" keyword is not standard across compilers, and this type allows inline to be configured on a per-compiler basis. Lin Ming.
Made the system global AcpiGbl_SystemAwakeAndRunning publically available. Added an extern for this boolean in acpixf.h. Some hosts utilize this value during suspend/restore operations. ACPICA BZ 869.
All code that implements error/warning messages with the "ACPI:" prefix has been moved to a new module, utxferror.c.
The UINT64_OVERLAY was moved to utmath.c, which is the only module where it is used. ACPICA BZ 829. Lin Ming, Bob Moore.
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.
Non-Debug Version: 89.1K Code, 19.0K Data, 108.1K Total
Debug Version: 165.1K Code, 51.9K Data, 217.0K Total
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/Disassembler: Write ACPI errors to stderr instead of the output file. This keeps the output files free of random error messages that may originate from within the namespace/interpreter code. Used this opportunity to merge all ACPI:-style messages into a single new module, utxferror.c. ACPICA BZ 866. Lin Ming, Bob Moore.
Tools: update some printfs for ansi warnings on size_t. Handle width change of size_t on 32-bit versus 64-bit generations. Lin Ming.
