git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux Pull an ACPI patch from Len Brown: "It fixes a D3 issue new in 3.4-rc1." By Lin Ming via Len Brown: * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux: ACPI: Fix D3hot v D3cold confusion
2012-05-05ACPI: Fix D3hot v D3cold confusionLin Ming
Before this patch, ACPI_STATE_D3 incorrectly referenced D3hot in some places, but D3cold in other places. After this patch, ACPI_STATE_D3 always means ACPI_STATE_D3_COLD; and all references to D3hot use ACPI_STATE_D3_HOT. ACPI's _PR3 method is used to enter both D3hot and D3cold states. What distinguishes D3hot from D3cold is the presence _PR3 (Power Resources for D3hot) If these resources are all ON, then the state is D3hot. If _PR3 is not present, or all _PR0 resources for the devices are OFF, then the state is D3cold. This patch applies after Linux-3.4-rc1. A future syntax cleanup may remove ACPI_STATE_D3 to emphasize that it always means ACPI_STATE_D3_COLD. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Acked-by: Rafael J.

2012-03-30ACPI: Add interface to register/unregister device to/from power resourcesLin Ming
Devices may share same list of power resources in _PR0, for example Device(Dev0) { Name (_PR0, Package (0x01) { P0PR, P1PR }) } Device(Dev1) { Name (_PR0, Package (0x01) { P0PR, P1PR } } Assume Dev0 and Dev1 were runtime suspended. Then Dev0 is resumed first and it goes into D0 state. But Dev1 is left in D0_Uninitialised state. This is wrong. In this case, Dev1 must be resumed too. In order to hand this case, each power resource maintains a list of devices which relies on it. When power resource is ON, it will check if the devices on its list can be resumed. The device can only be resumed when all the power resouces of its _PR0 are ON. Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2012-03-26ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFSLin Ming
Enhanced the sleep/wake interfaces to optionally execute the _GTS method (Going To Sleep), and the _BFS method (Back From Sleep). Windows apparently does not execute these methods, and therefore these methods are often untested. It has been seen on some systems where the execution of these methods causes errors and also prevents the machine from entering S5. It is therefore suggested that host operating systems do not execute these methods by default. In the future, perhaps these methods can be optionally executed based on the age of the system and/or what is the newest version of Windows that the BIOS asks for via _OSI.

The only left over hole in automatic cpufreq driver loading was the loading of ACPI cpufreq. This driver should be loaded when ACPI supports a _PDC method and the CPU vendor wants to use acpi cpufreq. Simply add a request module call to the acpi processor core driver when this is true.

With the conversion of atomicio's routines in place (see commits 6f68c91c55e and 700130b41f4), atomicio.[ch] can be removed, replacing the APEI specific pre-mapping capabilities with the more generalized versions that drivers/acpi/osl.c provides.

2012-01-21ACPI, APEI: Add 64-bit read/write support for APEI on i386Myron Stowe
Base ACPI (CA) currently does not support atomic 64-bit reads and writes (acpi_read() and acpi_write() split 64-bit loads/stores into two 32-bit transfers) yet APEI expects 64-bit transfer capability, even when running on 32-bit systems. This patch implements 64-bit read and write routines for APEI usage. This patch re-factors similar functionality introduced in commit 04c25997c97, bringing it into the ACPI subsystem in preparation for removing ./drivers/acpi/atomicio.[ch]. In the implementation I have replicated acpi_os_read_memory() and acpi_os_write_memory(), creating 64-bit versions for APEI to utilize, as opposed to something more elegant. My thinking is that we should attempt to see if we can get ACPI's CA/OSL changed so that the existing acpi_read() and acpi_write() interfaces are natively 64-bit capable and then subsequently remove the replication.

2011-11-06cpuidle: Single/Global registration of idle statesDeepthi Dharwar
This patch makes the cpuidle_states structure global (single copy) instead of per-cpu. The statistics needed on per-cpu basis by the governor are kept per-cpu. This simplifies the cpuidle subsystem as state registration is done by single cpu only. Having single copy of cpuidle_states saves memory. Rare case of asymmetric C-states can be handled within the cpuidle driver and architectures such as POWER do not have asymmetric C-states. Having single/global registration of all the idle states, dynamic C-state transitions on x86 are handled by the boot cpu. Here, the boot cpu would disable all the devices, re-populate the states and later enable all the devices, irrespective of the cpu that would receive the notification first.
