Optimizations like -O2 are seen to cause issues with some compilers.
Remove unneeded defines like DEBUG, _CONSOLE, etc.
Add _GNU_SOURCE to the Linux makefiles.
The only acpica tool that requires multithread support is
acpiexec. Along with previous changes to the actual source code,
this change removes unnecessary use of threading libraries.
Update purpose of the makefile and add a warning that the makefiles
are only suitable for use on Linux, with the Linux directory
structure (different than the native ACPICA directory structure.)
Shows 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.
Contains the complete overhaul of the GPE support code including
removal of _PRW execution, improved handling of wake GPEs, new
external interfaces, and implicit notify support. ACPICA BZ 858,
870,877. Matthew Garrett, Lin Ming, Bob Moore, Rafael Wysocki.
Note: This support is committed as a single patch here because
of multiple patch backporting from Linux and the resulting
interdependency issues.
See the ACPICA reference for full documentation.
This keeps the output files clean 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 bugzilla 866.
This function is not OS-dependent and has been replaced by
AcpiHwDerivePciId, which is now in the ACPICA core code.
Local implementations of AcpiOsDerivePciId are no longer
necessary and may be removed. ACPICA BZ 857.
Adds install/remove interfaces so that the host can dynamically
alter the global _OSI table. Also adds support for _OSI handlers.
Additional support: new debugger command (osi), and test support
in the acpiexec utility. Adds new file, utilities/utosi.c.
Lin Ming, Bob Moore. ACPICA bugzilla 836.
Update the iASL and AcpiExec makefiles so that the objects are
generated in the local directory. This prevents collisions due to
the generation of the common ACPICA code (which is compiled with
different options for both.) ACPICA BZ 864.
Adds typechecking for static (non-control-method) predefined names.
Migrates compiler to use the common predefined name table (acpredef.h).
Adds a single new file, aslpredef.c. ACPICA BZ 832.
This change will enable debug object output via a global variable,
AcpiGbl_EnableAmlDebugObject. This will help with remote machine
debugging. Also, moved all debug object support code to a new file,
executer/exdebug.c. Entire debug object module can now be configured
out of the ACPICA build if desired. Lin Ming, Bob Moore.
This change will repair (by sorting) packages returned by _ALR,
_PSS, and _TSS. Drivers can now assume that the packages are
correctly sorted. Adds one new file, namespace/nsrepair2.c
ACPICA BZ 784. Lin Ming, Bob Moore.
Add new file for handling of ASL External() statements. Consolidates
all such code, it is used only for iASL disassembler (not kernel code
or acpiexec.)
Completed a major update for the AcpiGetObjectInfo external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.
See the ACPICA Programmer Reference for details.
Added a reader/writer locking mechanism to allow multiple
concurrent namespace walks (readers), but a dynamic table
unload will have exclusive access to the namespace. This fixes
a problem where a table unload could delete the portion of
the namespace that is currently being examined by a walk.
Adds a new file, utlock.c that implements the reader/writer
lock mechanism. ACPICA BZ 749.
Validates predefined ACPI objects that appear in the namespace, at the
time they are evaluated. The argument count and the type of the returned
object are validated. The purpose of this validation is to detect problems
with the BIOS-exposed predefined ACPI objects before the results are
returned to the ACPI-related drivers.
