* ACPICA: Update _OSI with new Windows OS stringsBob Moore2009-09-091-0/+3
| | | | | | | | | Added strings for Windows server 2008, Windows Vista SP1, Windows 7, and Windows server 2008 R2. 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>
* ACPICA: Fix: Predefined object repair executed only onceBob Moore2009-08-271-0/+13
| | | | | | | | | | | | | | 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. ACPICA BZ 781. http://acpica.org/bugzilla/show_bug.cgi?id=781 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>
* ACPICA: Disable preservation of SCI enable bit (SCI_EN)Bob Moore2009-05-271-4/+7
| | | | | | | | | | | | Preserving this bit breaks some machines. Not preserving this bit seems to work OK in all cases, even though this goes against the ACPI spec. http://bugzilla.kernel.org/show_bug.cgi?id=13289 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>
* ACPICA: New: AcpiInstallMethod - install a single control methodLin Ming2009-05-271-0/+1
| | | | | | | | | This interface enables the override or creation of a single control method. Useful to repair a bug or install a missing method. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: resume: re-enable SCI-enable workaroundLin Ming2009-05-161-1/+6
| | | | | | | | | | | | | The BIOS bug workaround mistakenly got disabled when we followed the ACPI specification more closely by ignoring OS updates to that bit. (The BIOS is supposed to update SCI_EN, not the OS) http://bugzilla.kernel.org/show_bug.cgi?id=13289 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPICA: Clear PM register write-only bits on readingLin Ming2009-03-271-0/+4
| | | | | | | | | | | Affects PM1 Control register only. When reading the register, zero the write-only bits as per the ACPI spec. ACPICA BZ 443.

* ACPICA: New: I/O port protectionBob Moore2009-03-271-0/+24
| | | | | | | | | Protect certain I/O ports from reads/writes. Provides MS compatibility. New module, hwvalid.c 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>
* ACPICA: Preserve all PM control reserved and ignored bitsBob Moore2009-03-271-1/+9
| | | | | | | | | | As per the ACPI specification, preserve (read/modify/write) all bits that are defined as either reserved or ignored (PM control control registers only.)

* ACPICA: Fix AcpiWalkNamespace race condition with table unloadBob Moore2009-03-271-0/+8
| | | | | | | | | | | | | | | Added a reader/writer locking mechanism to allow multiple concurrent namespace walks (readers), but a dynamic table unload will have exclusive access to the namespace. This fixes a problem where a table unload could delete the portion of the namespace that is currently being examined by a walk. Adds a new file, utlock.c that implements the reader/writer lock mechanism.

* ACPICA: Add function to handle PM1 control registersBob Moore2009-03-261-6/+4
| | | | | | | | | | | | | Added acpi_hw_write_pm1_control. This function writes both of the PM1 control registers (A/B). These registers are different than than the PM1 A/B status and enable registers in that different values can be written to the A/B registers. Most notably, the SLP_TYP bits can be different, as per the values returned from the _Sx predefined methods.

* ACPICA: Remove redundant ACPI_BITREG_SLEEP_TYPE_BBob Moore2009-03-261-2/+2
| | | | | | | | | | | | This type is the same as TYPE_A. Removed this and all related instances. Renamed SLEEP_TYPE_A to simply SLEEP_TYPE.
