2008-10-22ACPICA: New: Validation for predefined ACPI methods/objectsBob Moore
Validates predefined ACPI objects that appear in the namespace, at the time they are evaluated. The argument count and the type of the returned object are validated. The purpose of this validation is to detect problems with the BIOS-exposed predefined ACPI objects before the results are returned to the ACPI-related drivers.

2008-10-22ACPI: Add "acpi.power_nocheck=1" to disable power state check in power ↵Zhao Yakui
transition Maybe the incorrect power state is returned on the bogus bios, which is different with the real power state. For example: the bios returns D0 state and the real power state is D3. OS expects to set the device to D0 state. In such case if OS uses the power state returned by the BIOS and checks the device power state very strictly in power transition, the device can't be transited to the correct power state. So the boot option of "acpi.power_nocheck=1" is added to avoid checking the device power in the course of device power transition. http://bugzilla.kernel.org/show_bug.cgi?id=8049 http://bugzilla.kernel.org/show_bug.cgi?id=11000 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Li Shaohua <shaohua.li@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2008-10-11ACPI: Enable EC device immediately after ACPI full initializationZhao Yakui
when there is no ECDT table and no _INI object for EC device, it will be enabled before scanning ACPI device. But it is too late after the following the commit is merged. >commit 7752d5cfe3d11ca0bb9c673ec38bd78ba6578f8e > Author: Robert Hancock <hancockr@shaw.ca> > Date: Fri Feb 15 01:27:20 2008 -0800 >x86: validate against acpi motherboard resources After the above commit is merged, OS will check whether MCFG area is reserved in ACPI motherboard resources by calling the function of acpi_get_devices when there exists MCFG table. In the acpi_get_devices the _STA object will be evaluated to check the status of the ACPI device. On some broken BIOS the MYEC object of EC device is initialized as one, which indicates that EC operation region is already accessible before enabling EC device.So on these broken BIOS the EC operation region will be accessed in course of evaluating the _STA object before enabling EC device, which causes that OS will print the following warning messages: >ACPI Error (evregion-0315): No handler for Region [EC__] (ffff88007f8145e8) [EmbeddedControl] [20080609] >ACPI Error (exfldio-0290): Region EmbeddedControl(3) has no handler [20080321] >ACPI Error (psparse-0530): Method parse/execution failed [\_SB_.PCI0.SBRG. EC__.BAT1._STA] (Node ffff81013fc17a00), AE_NOT_EXIST >ACPI Error (uteval-0233): Method execution failed [\_SB_.PCI0.SBRG.EC__.BAT1. _STA] (Node ffff81013fc17a00), AE_NOT_EXIST Although the above warning message is harmless, it looks confusing. So it is necessary to enable EC device as early as possible.Maybe it is appropriate to enable it immediately after ACPI full initialization. http://bugzilla.kernel.org/show_bug.cgi?id=11255 http://bugzilla.kernel.org/show_bug.cgi?id=11374 http://bugzilla.kernel.org/show_bug.cgi?id=11660 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Acked-by: Alexey Starikovskiy <astarikovskiy@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>

2008-09-23ACPI: fix hotplug raceZhang Rui
The hotplug notification handler and drivers' notification handler all run in one workqueue. Before hotplug removes an acpi device, the device driver's notification handler is already be recorded to run just after global notification handler. After hotplug notification handler runs, acpica will notice a NULL notification handler and crash. So now we run run hotplug in another workqueue and wait for all acpi notication handlers finish. This was found in battery hotplug, but actually all hotplug can be affected.
