* ACPI / ACPICA: Avoid crashing if _PRW is defined for the root objectRafael J. Wysocki2011-02-121-23/+26
| | | | | | | | | | | | | | Some ACPI BIOSes define _PRW for the root object which causes acpi_setup_gpe_for_wake() to crash when trying to dereference the bogus device_node pointer. Avoid the crash by checking if wake_device is not the root object before attempting to set up the "implicit notify" mechanism for it. The problem was introduced by commit bba63a296ffab20e08d9e8252d2f0d99 (ACPICA: Implicit notify support) that added the wake_device argument to acpi_setup_gpe_for_wake(). Signed-off-by: Rafael J.

| * ACPICA: Fix issues/fault with automatic "serialized" method supportLin Ming2011-01-1813-64/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | History: This support changes a method to "serialized" on the fly if the method generates an AE_ALREADY_EXISTS error, indicating the possibility that it cannot handle reentrancy. This fix repairs a couple of issues seen in the field, especially on machines with many cores. 1) Delete method children only upon the exit of the last thread, so as to not delete objects out from under running threads. 2) Set the "serialized" bit for the method only upon the exit of the last thread, so as to not cause deadlock when running threads attempt to exit. 3) Cleanup the use of the AML "MethodFlags" and internal method flags so that there is no longer any confustion between the two.

| * ACPICA: Fix namespace race conditionDana Myers2011-01-181-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes a race condition between method execution and namespace walks that can possibly fault. Problem was apparently introduced in version 20100528 as a result of a performance optimization that reduces the number of namespace walks upon method exit by using the delete_namespace_subtree function instead of the delete_namespace_by_owner function used previously. Bug is in the delete_namespace_subtree function.

| | * ACPI / ACPICA: Fix global lock acquisitionRafael J. Wysocki2011-01-071-39/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems with the ACPICA's current implementation of the global lock acquisition. First, acpi_ev_global_lock_handler(), which in fact is an interface to the outside of the kernel, doesn't validate its input, so it only works correctly if the other side (i.e. the ACPI firmware) is fully specification-compliant (as far as the global lock is concerned). Unfortunately, that's known not to be the case on some systems (i.e. we get spurious global lock signaling interrupts without the pending flag set on some systems). Second, acpi_ev_global_lock_handler() attempts to acquire the global lock on behalf of a thread waiting for it without checking if there actually is such a thread. Both of these shortcomings need to be addressed to prevent all possible race conditions from happening. Rework acpi_ev_global_lock_handler() so that it doesn't try to acquire the global lock and make it signal the availability of the global lock to the waiting thread instead. Make sure that the availability of the global lock can only be signaled when there is a thread waiting for it and that it can't be signaled more than once in a row (to keep acpi_gbl_global_lock_semaphore in balance).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ACPI GPEs initialization code has a problem that it enables some GPEs pointed to by device _PRW methods, generally intended for signaling wakeup events (system or device wakeup). These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds install/remove interfaces so that the host can dynamically alter the global _OSI table. Also adds support for _OSI handlers. Additional support: new debugger command (osi), and test support in the acpiexec utility. Adds new file, utilities/utosi.c. ACPICA bugzilla 836. The Linux OSL _OSI code is also changed. acpi_osi_setup can't call acpi_install/remove_interface because ACPICA is not initialized yet at this early time. So we just save the osi string in acpi_osi_setup and will handle it later in a new function acpi_osi_setup_late. http://www.acpica.org/bugzilla/show_bug.cgi?id=836 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>
| * | ACPICA: Revert "Revert "Enable multi-byte EC transfersBob Moore2010-10-013-49/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit f23b9c7(http://git.moblin.org/cgit.cgi/acpica/commit/?id=f23b9c7) The problem with this change was determined to be a problem with the FreeBSD host OSL (OS services layer), not with this patch itself. Therefore, re-introducing this change into the main ACPICA code.

| | * ACPI: enable repeated PCIEXP wakeup by clearing PCIEXP_WAKE_STS on resumeColin Ian King2010-09-281-0/+1
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Section 4.7.3.1.1 (PM1 Status Registers) of version 4.0 of the ACPI spec concerning PCIEXP_WAKE_STS points out in in the final note field in table 4-11 that if this bit is set to 1 and the system is put into a sleeping state then the system will not automatically wake. This bit gets set by hardware to indicate that the system woke up due to a PCI Express wakeup event, so clear it during acpi_hw_clear_acpi_status() calls to enable subsequent resumes to work.
