2009-01-08ACPICA: delete utcache.cLen Brown
ACPI_USE_LOCAL_CACHE will never be defined by the Linux kernel, and thus utcache.c will always be dead code. Signed-off-by: Len Brown <len.brown@intel.com>
2009-01-08ACPICA: delete acdisasm.hLen Brown
it is referenced only #ifdef ACPI_DISASSEMBLER, which is never set by the kernel. Signed-off-by: Len Brown <len.brown@intel.com>

2008-12-31ACPICA: FADT: Update error msgs for consistencyBob Moore
Update all messages so they look consistent. 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>
2008-12-31ACPICA: FADT: set acpi_gbl_use_default_register_widths to TRUE by defaultrobert.moore@intel.com
This returns the FADT support to the original behavior, which is to use default register widths. However, now check each register definition and report a warning if it differs from the default. This is a first step to moving away from the default widths, rather than outright believing the widths in all FADTs for all machines, considered rather dangerous until more data is obtained.

2008-12-31ACPICA: FADT parsing changes and fixesBob Moore
1) Update the register lengths for the PM1 event blocks. The length must be divided by two in order to use these to access the status registers. 2) Add run-time option to use default register lengths to override a faulty FADT. 3) Add warning message if any of the X64 address structures contain a length that does not match the legacy length earlier in the FADT. 4) Move all FADT warning messages into the ValidateFadt function.

2008-12-31ACPICA: Fixes for various ACPI data tablesBob Moore
Eliminate extraneous "zero length subtable" messages. Fix subtable output for ERST, MCFG, EINJ tables. Implement all subtables for HEST. 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>
2008-12-31ACPICA: Restructure includes into public/privateBob Moore
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.

Use new acpi_reset interface to write to reset register Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2008-12-31ACPICA: New: acpi_reset interface - write to reset registerBob Moore
Uses the FADT-defined reset register and reset value. Checks the FADT flags for the reset register supported bit. Supports reset register in memory or I/O space, but not in PCI config space since the host has the information to do it.

2008-12-31ACPICA: Move all public H/W interfaces to new hwxfaceBob Moore
Move public interfaces from hwregs.c to new file, hwxface.c - similar to the structure of the other ACPICA components. 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>
2008-12-31ACPICA: New: acpi_read and acpi_write public interfacesBob Moore
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.

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.)

2008-12-29ACPICA: Add Buffer->String conversion for predefined methodsBob Moore
For predefined methods (such as _BIF), add automatic conversion for objects that are required to be a String, but a Buffer was found instead. This can happen when reading string battery data from an operation region, because it used to be difficult to convert the data from buffer to string from within the ASL.

2008-12-29ACPICA: Allow multiple backslash prefix in namepathsLin Ming
In a fully qualified namepath, allow multiple backslash prefixes. This can happen because of the use of a double-backslash in strings (since backslash is the escape character) causing confusion.

2008-12-29ACPICA: Fix to allow aliases within ASL namepathsBob Moore
Fixes a problem where the use of an alias within a namepath would result in a not found error or cause the compiler to fault. Also now allows forward references from the Alias operator itself.

2008-12-29ACPICA: Add support to externally execute _OSI methodBob Moore
The current implemenation of _OSI within ACPICA only allows other control methods to execute _OSI. This change allows the host OS to execute _OSI via the AcpiEvaluateObject interface. _OSI is a special method -- it does not exist in the AML code, it is implemented within ACPICA.

2008-12-29ACPICA: Add global pointer for FACS table to simplify FACS accessBob Moore
Use a global pointer instead of using AcpiGetTableByIndex for each FACS access. This simplifies the code for the Global Lock and the Firmware Waking Vector(s).

2008-12-29ACPICA: Add a mechanism to escape infinite AML While() loopsBob Moore
Add a loop counter to force exit from AML While loops if the count becomes too large. This can occur in poorly written AML when the hardware does not respond within a while loop and the loop does not implement a timeout. The maximum loop count is configurable. A new exception code is returned when a loop is broken, AE_AML_INFINITE_LOOP. Bob Moore, Alexey Starikovskiy.

2008-12-29ACPICA: Optimize execution of AML While loopsBob Moore
Previously, a control state object was allocated and freed for each execution of the loop. The optimization is to simply reuse the control state for each iteration. This speeds up the raw loop execution time by about 5%. 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>

2008-12-29ACPICA: Update FACS waking vector interfacesBob Moore
Split AcpiSetFirmwareWakingVector into two: one for the 32-bit vector, another for the 64-bit vector. This is required because the host OS must setup the wake much differently for each vector (real vs. protected mode, etc.) and the interface should not be deciding which vector to use. Also eliminate the GetFirmwareWakingVector interface, as it served no purpose (only the firmware reads the vector, OS only writes the vector.)

2008-12-24x86: disable X86_PTRACE_BTSIngo Molnar
there's a new ptrace arch level feature in .28: config X86_PTRACE_BTS bool "Branch Trace Store" it has broken fork() handling: the old DS area gets copied over into a new task without clearing it. Fixes exist but they came too late: c5dee61: x86, bts: memory accounting bf53de9: x86, bts: add fork and exit handling and are queued up for v2.6.29. This shows that the facility is still not tested well enough to release into a stable kernel - disable it for now and reactivate in .29. In .29 the hardware-branch-tracer will use the DS/BTS facilities too - hopefully resulting in better code. Signed-off-by: Ingo Molnar <mingo@elte.hu>
