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.
This message happens when the package element list is longer than
the declared length of the package. Changed to an info message
because this condition is not actually an error. It is caused by
the BIOS attempting to truncate the package on the fly by adjusting
the package element count at the start of the package definition.
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.
This change correctly implements the Switch operator with a surrounding
While(1) so that the Break statement works as expected.
ACPICA BZ 461. 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.)
If a custom address space handler is installed by the host before the
"initialize operation regions" phase of the ACPICA initialization, any
_REG methods for that address space could be executed twice. This change
fixes the problem. ACPICA BZ 427. Lin Ming.
References to external names in secondary tables that contained one or
more carats (parent-prefixes) were not handled correctly.
ACPICA BZ 806. Lin Ming.
_MAT can inadvertently return an Integer instead of a Buffer if
the return value has been read from a Field whose width is less
than or equal to the global integer width (32 or 64 bits).
ACPICA BZ 810. Lin Ming.
Add support for execution of an _INI method at the namespace root.
Although not defined in the ACPI specification, this support was
added to Windows around the Vista timeframe. It is added here
for Windows compatibility.
Fixes a possible memory leak in the interpreter for package objects if the
package initializer list is longer than the defined size of the package. This
apparently can only happen if the BIOS changes the package size on the fly
(seen in a _PSS object), as both iASL and the other compiler do not allow this.
The interpreter will truncate the package to the defined size (and issue an
error message), but can leave the extra objects undeleted if they have been
pre-created during the argument processing (such is the case if the package
consists of a number of sub-packages as in the _PSS.) ACPICA BZ 805.
Fixes a compatibility issue when the same buffer or string is
stored to itself. This has been seen in the field. Previously,
ACPICA would zero out the buffer/string. Now, the operation is
treated as a noop. ACPICA BZ 803. Lin Ming.
Allows multiple additional search paths for include files. Directories
are searched in the order specified on the command line (after the
local directory is searched.)
