2014-02-27ACPICA: Restore code that repairs NULL package elements in return values.Lv Zheng1-4/+21
The original code was lost accidently, it was not generated along with the following commit of mechanism improvements and thus not get merged: Commit: d5a36100f62fa6db5541344e08b361b34e9114c5 Subject: ACPICA: Add mechanism for early object repairs on a per-name basis Adds the framework to allow object repairs very early in the return object analysis. Enables repairs like string->unicode, etc. This patch restores the implementation of the NULL element repair code for ACPI_RTYPE_NONE. In the original design, ACPI_RTYPE_NONE is defined to collect simple NULL object repairs. Lv Zheng.

2012-03-30ACPICA: Object repair code: Support to add Package wrappersBob Moore1-101/+58
Repair a common problem with objects that are defined to return a variable-length Package of sub-objects. If there is only one sub-object, some BIOS code mistakenly simply declares the single object instead of a Package with one sub-object. This function attempts to repair this error by wrapping a Package object around the original object, creating the correct and expected Package with one sub-object.

This change adds another group of predefined names to the list of names eligible to have NULL package elements dynamically removed. This group is the names that return a single variable-length package containing simple data types such as integers, buffers, strings. This includes: _ALx,_BCL,_CID, _DOD,_EDL,_FIX,_PCL,_PLD,_PMD,_PRx,_PSL,_Sx, and _TZD. http://www.acpica.org/bugzilla/show_bug.cgi?id=914 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: Predefined name repair: fix NULL package elementsBob Moore1-0/+173
For the predefined methods that return fixed-length packages (or subpackages), attempt repair for a NULL element.

2009-12-15ACPICA: Remove messages if predefined repair(s) are successfulBob Moore1-14/+18
Repair mechanism was considered too wordy. Now, messages are only unconditionally emitted if the return object cannot be repaired.

2009-12-15ACPICA: Add more conversions to predefined name repair moduleBob Moore1-76/+327
This change enhances the automatic repairs/conversions for predefined name return values to make Integers, Strings, and Buffers fully interchangeable.

2009-11-24ACPICA: Reduce severity of predefined repair messages, Warning to InfoBob Moore1-4/+4

2009-08-28ACPICA: Add repair for predefined methods that return nested packagesBob Moore1-0/+52
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.
