* | ACPI / ACPICA: Implicit notify for multiple devicesRafael J. Wysocki2011-02-24
|/ | | | | | | | | | | | | | | | | Commit bba63a2 (ACPICA: Implicit notify support) introduced a mechanism that causes a notify request of type ACPI_NOTIFY_DEVICE_WAKE to be queued automatically by acpi_ev_asynch_execute_gpe_method() for the device whose _PRW points to the GPE being handled if that GPE is not associated with an _Lxx/_Exx method. However, it turns out that on some systems there are multiple devices with _PRW pointing to the same GPE without _Lxx/_Exx and the mechanism introduced by commit bba63a2 needs to be extended so that "implicit" notify requests of type ACPI_NOTIFY_DEVICE_WAKE can be queued automatically for all those devices at the same time.

* ACPI / ACPICA: Avoid crashing if _PRW is defined for the root objectRafael J. Wysocki2011-02-11
| | | | | | | | | | | | | | 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 Ming2011-01-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Wysocki2011-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

This touches lots of files mainly because of how the io_apic nmi_watchdog was implemented. Now that the io_apic nmi_watchdog is forever gone, remove all its fingers. Most of this code was not being exercised by virtue of nmi_watchdog != NMI_IO_APIC, so there shouldn't be anything to risky here.

| * ACPI / ACPICA: Defer enabling of runtime GPEs (v3)Rafael J. Wysocki2010-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | Subject: [PATCH] ACPICA: Fix Scope() op in module level codeBob Moore2010-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some Panasonic Toughbooks create nodes in module level code. Module level code is the executable AML code outside of control method, for example, below AML code creates a node \_SB.PCI0.GFX0.DD02.CUBL If (\_OSI ("Windows 2006")) { Scope (\_SB.PCI0.GFX0.DD02) { Name (CUBL, Ones) ... } } Scope() op does not actually create a new object, it refers to an existing object(\_SB.PCI0.GFX0.DD02 in above example). However, for Scope(), we want to indeed open a new scope, so the child nodes(CUBL in above example) can be created correctly under it. https://bugzilla.kernel.org/show_bug.cgi?id=19462 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>
