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 implementatio=
ns of this function were not OS-dependent and are now obsolete and can be r=
emoved from all host OSLs. This function has been replaced by AcpiHwDeriveP=
ciId, 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 probl=
ems 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 wi=
th 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 alw=
ays UINT64. This simplifies the ACPICA code, especially any printf output. =
UINT64 is the only common data type for all thread_id types across all oper=
ating systems. It is now up to the host OSL to cast the native thread_id ty=
pe 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 acpi=
ca.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 muc=
h larger code and data size.

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 originat=
e from within the namespace/interpreter code. Used this opportunity to merg=
e 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.
