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.
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 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.
Add limited support for executable AML code that exists outside of
any control method. This type of code has been illegal since ACPI 2.0.
The code must exist in an If/Else/While block. All AML tables are
supported, including tables that are dynamically loaded.
ACPICA BZ 762. Lin Ming.
Fixes a problem where a predefined method is defined to return a
variable-length Package of sub-packages. If the length is one, the
BIOS code occasionally creates a simple single package with no
sub-packages. This code attempts to fix the problem by wrapping
a new package object around the existing package. ACPICA BZ 790.
Handler was never invoked. Now invoked if/when host node is deleted.
Data object was not automatically deleted when host node was deleted.
Interface to handler had an unused parameter, removed it.
ACPICA BZ 778.
Add 2009 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.
Merge the code that validates control method argument counts into
the predefined validation module. Eliminates possible multiple
warnings for incorrect counts.
For predefined methods (such as _BIF), add automatic conversion for
objects that are required to be a String, but a Buffer was found
instead. This can happen when reading string battery data from
an operation region, because it used to be difficult to convert
the data from buffer to string from within the ASL. Linux BZ 11822.
Removed the "$Revision" number that appeared in each module header.
This version number was useful under SourceSafe and CVS, but has no
meaning under git. It is not only incorrect, it could also be
misleading.
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.
Add error check after all calls to AcpiNsGetPathnameLength.
Add status return from AcpiNsBuildExternalPath and check after all calls.
Add parameter validation to AcpiUtInitializeBuffer.
Reported by and initial patch by Ingo Molnar.
Added 2008 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
Fixed a problem with the Load and LoadTable operators where the table location within the namespace was ignored. Instead, the table was always loaded into the root or current scope.
Added 2007 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
Fixed a problem with a possible race condition between threads executing AcpiWalkNamespace and the AML interpreter. This condition was removed by modifying AcpiWalkNamespace to (by default) ignore all temporary namespace entries created during any concurrent control method execution
