27 September 2013. Summary of changes for version 20130927:
This release is available at https://acpica.org/downloads
1) ACPICA kernel-resident subsystem:
Fixed a problem with store operations to reference objects. This change
fixes a problem where a Store operation to an ArgX object that contained a
reference to a field object did not complete the automatic dereference and
then write to the actual field object. Instead, the object type of the
field object was inadvertently changed to match the type of the source
operand. The new behavior will actually write to the field object (buffer
field or field unit), thus matching the correct ACPI-defined behavior.
Implemented support to allow the host to redefine individual OSL
prototypes. This change enables the host to redefine OSL prototypes found
in the acpiosxf.h file. This allows the host to implement OSL interfaces
with a macro or inlined function. Further, it allows the host to add any
additional required modifiers such as __iomem, __init, __exit, etc., as
necessary on a per-interface basis. Enables maximum flexibility for the
OSL interfaces. Lv Zheng.
Hardcoded the access width for the FADT-defined reset register. The ACPI
specification requires the reset register width to be 8 bits. ACPICA now
hardcodes the width to 8 and ignores the FADT width value. This provides
compatibility with other ACPI implementations that have allowed BIOS code
with bad register width values to go unnoticed. Matthew Garett, Bob Moore,
Lv Zheng.
Changed the position/use of the ACPI_PRINTF_LIKE macro. This macro is used
in the OSL header (acpiosxf). The change modifies the position of this
macro in each instance where it is used (AcpiDebugPrint, etc.) to avoid
build issues if the OSL defines the implementation of the interface to be
an inline stub function. Lv Zheng.
Deployed a new macro ACPI_EXPORT_SYMBOL_INIT for the main ACPICA
initialization interfaces. This change adds a new macro for the main init
and terminate external interfaces in order to support hosts that require
additional or different processing for these functions. Changed from
ACPI_EXPORT_SYMBOL to ACPI_EXPORT_SYMBOL_INIT for these functions. Lv
Zheng, Bob Moore.
Cleaned up the memory allocation macros for configurability. In the common
case, the ACPI_ALLOCATE and related macros now resolve directly to their
respective AcpiOs* OSL interfaces. Two options:
1) The ACPI_ALLOCATE_ZEROED macro uses a simple local implementation by
default, unless overridden by the USE_NATIVE_ALLOCATE_ZEROED define.
2) For AcpiExec (and for debugging), the macros can optionally be resolved
to the local ACPICA interfaces that track each allocation (local tracking
is used to immediately detect memory leaks).
Lv Zheng.
Simplified the configuration for ACPI_REDUCED_HARDWARE. Allows the kernel
to predefine this macro to either TRUE or FALSE during the system build.
Replaced __FUNCTION_ with __func__ in the gcc-specific header.
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: 95.8K Code, 27.0K Data, 122.8K Total
Debug Version: 185.2K Code, 77.2K Data, 262.4K Total
Previous Release:
Non-Debug Version: 96.7K Code, 27.1K Data, 123.9K Total
Debug Version: 184.4K Code, 76.8K Data, 261.2K Total
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented wildcard support for the -e option. This simplifies use
when there are many SSDTs that must be included to resolve external method
declarations. ACPICA BZ 1041. Example:
iasl -e ssdt*.dat -d dsdt.dat
AcpiExec: Add history/line-editing for Unix/Linux systems. This change
adds a portable module that implements full history and limited line
editing for Unix and Linux systems. It does not use readline() due to
portability issues. Instead it uses the POSIX termio interface to put the
terminal in raw input mode so that the various special keys can be trapped
(such as up/down-arrow for history support and left/right-arrow for line
editing). Uses the existing debugger history mechanism. ACPICA BZ 1036.
AcpiXtract: Add support to handle (ignore) "empty" lines containing only
one or more spaces. This provides compatible with early or different
versions of the AcpiDump utility. ACPICA BZ 1044.
AcpiDump: Do not ignore tables that contain only an ACPI table header.
Apparently, some BIOSs create SSDTs that contain an ACPI table header but
no other data. This change adds support to dump these tables. Any tables
shorter than the length of an ACPI table header remain in error (an error
message is emitted). Reported by Yi Li.
Debugger: Echo actual command along with the "unknown command" message.
