2010-05-06ACPICA: Add GPE support for dynamically loaded ACPI tablesBob Moore1-0/+4
For all GPEs, including FADT-based and GPE Block Devices, execute any _PRW methods in the new table, and process any _Lxx/_Exx GPE methods in the new table. Any runtime GPE that is referred to by an _Lxx/_Exx method in the new table is immediately enabled.

Original fields were not very descriptive and led to maintenance problems. New fields should help to understand the existing 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>
2010-04-20ACPICA: Minimize the differences between linux GPE code and ACPICA code baseLin Ming1-2/+3
We have ported Rafael's major GPE changes (ACPI: Use GPE reference counting to support shared GPEs) into ACPICA code base. But the port and Rafael's original patch have some differences, so we made below patch to make linux GPE code consistent with ACPICA code base. Most changes are about comments and coding styles. Other noticeable changes are based on: Rafael: Reduce code duplication related to GPE lookup https://patchwork.kernel.org/patch/86237/ Rafael: Always use the same lock for GPE locking https://patchwork.kernel.org/patch/90471/ A new field gpe_count in struct acpi_gpe_block_info to record the number of individual GPEs in block. Rename acpi_ev_save_method_info to acpi_ev_match_gpe_method. Signed-off-by: Rafael J.

2010-02-23ACPI: Use GPE reference counting to support shared GPEsRafael J. Wysocki1-0/+2
ACPI GPEs may map to multiple devices. The current GPE interface only provides a mechanism for enabling and disabling GPEs, making it difficult to change the state of GPEs at runtime without extensive cooperation between devices. Add an API to allow devices to indicate whether or not they want their device's GPE to be enabled for both runtime and wakeup events. Remove the old GPE type handling entirely, which gets rid of various quirks, like the implicit disabling with GPE type setting. This requires a small amount of rework in order to ensure that non-wake GPEs are enabled by default to preserve existing behaviour. Based on patches from Matthew Garrett <mjg@redhat.com>.

2010-01-22ACPICA: Remove obsolete ACPI_INTEGER (acpi_integer) typeBob Moore1-1/+1
This type was introduced as the code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with 64-bit integers). It is now obsolete and this change removes it from the ACPICA code base, replaced by u64. The original typedef has been retained for now for compatibility with existing device driver code.

2010-01-22ACPICA: Predefined name repair: fix NULL package elementsBob Moore1-0/+1
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>

2009-08-27ACPICA: Fix: Predefined object repair executed only onceBob Moore1-0/+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.

2009-05-27ACPICA: Disable preservation of SCI enable bit (SCI_EN)Bob Moore1-4/+7

2009-03-27ACPICA: Fix AcpiWalkNamespace race condition with table unloadBob Moore1-0/+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.

2009-03-26ACPICA: Add function to handle PM1 control registersBob Moore1-6/+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.
