This feature is optional and is enabled if the BIOS requests any Windows
OSI strings. It can also be enabled by the host OS. Matthew Garrett,
Bob Moore.
On control method exit, only walk the namespace if the method is known
to have created namespace objects outside of its local scope.
Bob Moore, Alexey Starikovskiy.
-dt option will disable the tracking mechanism, which improves performance
considerably. Also restructured the options into -d (disable) and -e (enable) options.
These objects are defined by "Windows Instrumentation", and are not
part of the ACPI spec. Adds compiler support and runtime typechecking
support in the ACPICA core. ACPICA BZ 860.
This change implements the rules for LEN/MIF/MAF/MIN/MAX/GRA that come
from the ACPI specification (Table 6-40). Also added a special
case for IO descriptor where MIN/MAX are both start addresses, not
a start and end address. ACPICA BZ 840.
For all GPEs, including FADT-based and GPE Block Devices, execute
any _PRW methods in the new table, and process any _Lxx/_Exx GPE
methods in the new table. Any runtime GPE that is referred to by
an _Lxx/_Exx method in the new table is immediately enabled.
ACPICA BZ 833. Lin Ming, Bob Moore.
Adds a reference count mechanism to simplify support of shared GPEs that
require multiple device drivers. Several external interfaces have changed.
One external interface has been removed.
Changed:
AcpiEnableGpe
AcpiDisableGpe
AcpiClearGpe
AcpiGetGpeStatus
Removed:
AcpiSetGpeType
New:
AcpiSetGpe

Optionally copy the entire DSDT to local memory (instead of simply
mapping it.) There are some BIOSs that corrupt or replace the original
DSDT, creating the need for this option. Default is FALSE, do not copy
the DSDT.
This change adds support to detect a DSDT that has been corrupted
and/or replaced from outside the OS (by firmware). This is typically
catastrophic for the system, but has been seen on some machines.
Lin Ming, Bob Moore.
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 type was introduced as the code was migrated from ACPI 1.0 (with 32-bit
AML integers) to ACPI 2.0 (with 64-bit integers). It is now obsolete and
this change removes it from the ACPICA code base, replaced by UINT64.
The original typedef has been retained for now for compatibility with
existing device driver code.
For the predefined methods that return fixed-length packages (or subpackages),
attempt repair for a NULL element. Create an Integer of value 0, a NULL
String, or a zero-length buffer as appropriate. ACPICA BZ 818.
Lin Ming, Bob Moore.
Add 2010 copyright to all module headers and signons, including the Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, and all utilities.
Added several new options for the gcc-4 generation, and updated the source
accordingly. This includes some code restructuring to eliminate unreachable
code, elimination of some gotos, elimination of unused return values, and
some additional casting.
This change will automatically remove embedded and trailing NULL package
elements from returned package objects that are defined to containe a
variable number of sub-packages. The driver is then presented with
a package with no null elements to deal with. ACPICA BZ 819.
This change enables the execution of _REG methods that appear in the
same scope as the module-level code, in resonse to an operation region
declaration within the module-level code.
Repair mechanism was considered too wordy. Now, messages are only
unconditionally emitted if the return object cannot be repaired.
Existing messages for successful repairs were converted to
ACPI_DEBUG_PRINT messages for now. ACPICA BZ 827.
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.
The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779. Lin Ming.
Ensure that memory mappings created for operation regions do
not cross page boundaries. Crossing a page boundary while mapping
regions can cause warnings if the pages have different attributes.
Such regions are probably BIOS bugs, and this is the workaround.
Linux BZ 14445. Lin Ming.
Since the object was successfully repaired, a Warning is too severe.
Reduced to Info for now. We may eventually change these messages
to debug-only. ACPICA BZ 812.
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.)
