| | | | | | | | | | Fixed a problem with a possible race condition between threads executing AcpiWalkNamespace and the AML interpreter.

* ACPICA: Eliminate control method 2-pass parse/execute.Valery Podrezov2007-02-02
| | | | | | | | | | | Completed an AML interpreter performance enhancement for control method execution. Previously a 2-pass parse/execution, control methods are now completely parsed and executed in single pass. This improves overall interpreter performance by ~25%, reduces code size, and reduces CPU stack use.

* 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.

* ACPICA: Delete recursive feature of ACPI Global LockBob Moore2007-02-02
| | | | | | | | | | | | | 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.

* [PATCH] ACPI: fix cpufreq regressionIngo Molnar2007-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recently cpufreq support on my laptop (Lenovo T60) broke completely: when it's plugged into AC it would never go higher than 1 GHz - neither 1.3 GHz nor 1.83 GHz is possible - no matter which governor (userspace, speed or ondemand) is used. After some cpufreq debugging i tracked the regression back to the following (totally correct) bug-fix commit: commit 0916bd3ebb7cefdd0f432e8491abe24f4b5a101e Author: Dave Jones <davej@redhat.com> Date: Wed Nov 22 20:42:01 2006 -0500 [PATCH] Correct bound checking from the value returned from _PPC method. This bugfix, which makes other laptops work, made a previously hidden (BIOS) bug visible on my laptop. The bug is the following: if the _PPC (Performance Present Capabilities) optional ACPI object is queried /after/ bootup then the BIOS reports an incorrect value of '2'. My laptop (Lenovo T60) has the following performance states supported: 0: 1833000 1: 1333000 2: 1000000 Per ACPI specification, a _PPC value of '0' means that all 3 performance states are usable. A _PPC value of '1' means states 1 .. 2 are usable, a value of '2' means only state '2' (slowest) is usable. now, the _PPC object is optional, and it also comes with notification. Furthermore, when a CPU object is initialized, the _PPC object is initialized as well. So the following evaluation of the _PPC object is superfluous: [<c028ba5f>] acpi_processor_get_platform_limit+0xa1/0xaf [<c028c040>] acpi_processor_register_performance+0x3b9/0x3ef [<c0111a85>] acpi_cpufreq_cpu_init+0xb7/0x596 [<c03dab74>] cpufreq_add_dev+0x160/0x4a8 [<c02bed90>] sysdev_driver_register+0x5a/0xa0 [<c03d9c4c>] cpufreq_register_driver+0xb4/0x176 [<c068ac08>] acpi_cpufreq_init+0xe5/0xeb [<c010056e>] init+0x14f/0x3dd And this is the point where my laptop's BIOS returns the incorrect value of '2'. Note that it has not sent any notification event, so the value is probably not really intentional (possibly spurious), and Windows likely doesnt query it after bootup either. Maybe the value is kept at '2' normally, and is only set to the real value when a true asynchronous event (such as AC plug event, battery switch, etc.) occurs. So i /think/ this is a grey area of the ACPI spec: per the letter of the spec the _PPC value only changes when notified, so there's no reason to query it after the system has booted up. So in my opinion the best (and most compatible) strategy would be to do the change below, and to not evaluate the _PPC object in the acpi_processor_get_performance_info() call, but only evaluate it if _PPC is present during CPU object init, or if it's notified during an asynchronous event. This change is more permissive than the previous logic, so it definitely shouldnt break any existing system. This also happens to fix my laptop, which is merrily chugging along at 1.83 GHz now. Yay!
