* ACPICA: Updates for Debug object outputBob Moore2008-04-22
| | | | | | | | | | Implemented several improvements for the output of the ASL "Debug" object to clarify and keep all data for a given object on one output line.

* ACPICA: Update behavior of CopyObject to match ACPI specLin Ming2008-04-22
| | | | | | | | | | | | | | | | Fixed a problem where a CopyObject to RegionField, BankField, and IndexField objects did not perform an implicit conversion as it should. These types must retain their initial type permanently as per the ACPI specification. However, a CopyObject to all other object types should not perform an implicit conversion, as per the ACPI specification. http://www.acpica.org/bugzilla/show_bug.cgi?id=388 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | | | | Fixed a problem with the SizeOf operator when used with Package and Buffer objects.

| | | | | | | | | | | | This reverts commit c0d127b56937c3e72c2b1819161d2f6718eee877. These changes to AML locking were made to allow Notify handlers to be called on the stack and not deadlock.

* ACPICA: fix AML mutex re-entrancyAlexey Starikovskiy2007-02-15
| | | | | | | | | | | | | | | | | | ACPI AML supports "serialized" methods which are protected by an implicit mutex. The mutex is re-entrant for that AML thread to allow recursion. However, Linux implements notify() by creating a new AML thread. So for systems where notify() re-enters a serialized method, deadlock results. The fix is to use the Linux thread_id as the key to allowing re-entrancy, not the AML thread pointer. http://bugzilla.kernel.org/show_bug.cgi?id=5534 Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

| | | | | | | | | | | | Support for 16-bit ACPICA has been completely removed since it is no longer necessary and it clutters the code.

* ACPICA: Re-implement interpreters' "serialized mode"Bob Moore2007-02-02
| | | | | | | | | | | | | | | Enhanced the implementation of the interpreters' serialized mode (boot with "acpi_serialize" to set acpi_glb_all_methods_serialized flag.) When this mode is specified, instead of creating a serialization semaphore per control method, the interpreter lock is simply no longer released before a blocking operation during control method execution. This effectively makes the AML Interpreter single-threaded. The overhead of a semaphore per-method is eliminated.

| | | | | | | | | | | | | The Table Manager component has been completely redesigned and reimplemented. The new design is much simpler, and reduces the overall code and data size of the kernel-resident ACPICA by approximately 5%. Also, it is now possible to obtain the ACPI tables very early during kernel initialization, even before dynamic memory management is initialized.

| | | | | | | | | | | | | Completed a new design and implementation for the ACPI Global Lock support. On the OS side, the global lock is now treated as a standard AML mutex. Previously, multiple OS threads could acquire the global lock simultaneously, but this could cause the BIOS to be starved by the lock in cases such as the Embedded Controller driver, where there is a tight coupling between the OS and the BIOS.
