ACPICA: create acpica/ directory

2009-01-09T08:30:47+00:00

also, delete sleep/ and delete ACPI_CFLAGS from Makefile Signed-off-by: Len Brown

ACPICA: Restructure includes into public/private

2008-12-31T06:15:40+00:00

acpi.h now includes only the "public" acpica headers. All other acpica headers are "private" and should not be included by acpica users. One new file, accommon.h is used to include the commonly used private headers for acpica code generation. Future plans are to move all private headers to a new subdirectory.

ACPICA: New: acpi_read and acpi_write public interfaces

2008-12-31T06:12:56+00:00

Changed the acpi_hw_low_level_read and acpi_hw_low_level_write functions to the public acpi_read and acpi_write to allow direct access to ACPI registers. Removed the "width" parameter since the width can be obtained from the input GAS structure. Updated the FADT initialization to setup the GAS structures with the proper widths. Some widths are still hardcoded because many FADTs have incorrect register lengths. Signed-off-by: Bob Moore Signed-off-by: Len Brown

ACPICA: New: acpi_get_gpe_device interface

2008-12-31T06:10:24+00:00

This function maps an input GPE index to a GPE block device. Also Added acpi_current_gpe_count to track the current number of GPEs that are being managed by the ACPICA core (both FADT-based GPEs and the GPEs contained in GPE block devices.) Modify drivers/acpi/system.c to use these 2 new interfaces Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPI: Enhance /sys/firmware/interrupts to allow enable/disable/clear from user-space

2008-07-16T21:27:04+00:00

Allow users to enable/disable/clear a specific & valid GPE/Fixed Event in user space. This is useful for debugging, especially for some interrupt storm issues. All wakeup GPEs are disabled and they can not be enabled at runtime, and we mark them as invalid. All GPEs that don't have a _Lxx/_Exx method are marked as invalid. All Fixed Events that don't have an event handler are marked as invalid and they can't be enabled until an event handler is registered.

Make GPE disable more robust

2008-07-16T21:27:01+00:00

Implemented another change for the GPE disable. We now perform a read-change-write of the enable register instead of simply writing out the cached enable mask. This will prevent inadvertent enabling of GPEs if a rogue GPE is received during initialization (before GPE handlers are installed.) http://bugzilla.kernel.org/show_bug.cgi?id=6217 Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown Signed-off-by: Andi Kleen

ACPICA: update Intel copyright

Signed-off-by: Len Brown

2007-02-03T02:14:31+00:00

Added 2007 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities. Signed-off-by: Alexey Starikovskiy Signed-off-by: Len Brown

ACPICA: Store GPE number instead of bitmask

2007-02-03T02:14:23+00:00

Update internal GPE data structure to simplify debug, use gpe_number instead of register bitmask. Signed-off-by: Bob Moore Signed-off-by: Len Brown

ACPI: ACPICA 20060421

2006-06-14T06:30:55+00:00

Removed a device initialization optimization introduced in 20051216 where the _STA method was not run unless an _INI was also present for the same device. This optimization could cause problems because it could allow _INI methods to be run within a not-present device subtree (If a not-present device had no _INI, _STA would not be run, the not-present status would not be discovered, and the children of the device would be incorrectly traversed.) Implemented a new _STA optimization where namespace subtrees that do not contain _INI are identified and ignored during device initialization. Selectively running _STA can significantly improve boot time on large machines (with assistance from Len Brown.) Implemented support for the device initialization case where the returned _STA flags indicate a device not-present but functioning. In this case, _INI is not run, but the device children are examined for presence, as per the ACPI specification. Implemented an additional change to the IndexField support in order to conform to MS behavior. The value written to the Index Register is not simply a byte offset, it is a byte offset in units of the access width of the parent Index Field. (Fiodor Suietov) Defined and deployed a new OSL interface, acpi_os_validate_address(). This interface is called during the creation of all AML operation regions, and allows the host OS to exert control over what addresses it will allow the AML code to access. Operation Regions whose addresses are disallowed will cause a runtime exception when they are actually accessed (will not affect or abort table loading.) Defined and deployed a new OSL interface, acpi_os_validate_interface(). This interface allows the host OS to match the various "optional" interface/behavior strings for the _OSI predefined control method as appropriate (with assistance from Bjorn Helgaas.) Restructured and corrected various problems in the exception handling code paths within DsCallControlMethod and DsTerminateControlMethod in dsmethod (with assistance from Takayoshi Kochi.) Modified the Linux source converter to ignore quoted string literals while converting identifiers from mixed to lower case. This will correct problems with the disassembler and other areas where such strings must not be modified. The ACPI_FUNCTION_* macros no longer require quotes around the function name. This allows the Linux source converter to convert the names, now that the converter ignores quoted strings. Signed-off-by: Bob Moore Signed-off-by: Len Brown
