2010-01-22ACPICA: Predefined name repair: fix NULL package elementsBob Moore1-3/+24
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. http://www.acpica.org/bugzilla/show_bug.cgi?id=818 Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2010-01-22ACPICA: Update all ACPICA copyrights and signons to 2010Bob Moore1-1/+1
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.

2010-01-22ACPICA: Update for new gcc-4 warning optionsBob Moore1-13/+11
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.

2009-12-15ACPICA: Predefined name repair: automatically remove null package elementsBob Moore1-45/+14
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.

2009-12-15ACPICA: Conditionally perform complex per-predefined-name repairsBob Moore1-13/+24
Only attempt the "complex" repairs (package sorting, buffer expansion) if the previous "generic" validation and repair was successful. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-12-15ACPICA: Remove messages if predefined repair(s) are successfulBob Moore1-5/+5
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.

2009-12-15ACPICA: Move Package-to-Buffer repair code into common ToBuffer functionBob Moore1-4/+7
Move code specific to _FDE and _GTM into the generic repair code. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2009-12-15ACPICA: Add repair for bad _FDE/_GTM buffersBob Moore1-8/+6
The expected return value for both names is a Buffer of 5 DWORDS. This repair fixes two possible problems (both seen in the field): A package of integers is returned, or a buffer of BYTEs is returned.

2009-11-24ACPICA: Add repair for predefined methods that must return sorted listsBob Moore1-0/+6
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, nsrepair2.c.

2009-11-24ACPICA: Fix possible fault if return Package objects contain NULL elementsBob Moore1-1/+42
For predefined name validation. Also adds a warning if a NULL element is followed by any non-null elements.

2009-08-28ACPICA: ACPI 4.0 : Add new return package type, restructure module.Bob Moore1-134/+192
Added one new package type, a package that contains a revision number and a variable number of sub-packages. Restructured the module to put the sub-package list traversal in a separate function.

2009-08-28ACPICA: Add repair for predefined methods that return nested packagesBob Moore1-2/+28
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.

2009-08-27ACPICA: Fix: Predefined object repair executed only onceBob Moore1-164/+205
This fixes a problem where the code that attempts to repair/convert an object of incorrect type is only executed on the first time the predefined method is called. The mechanism that disables warnings on subsequent calls was interfering with the repair mechanism.
