| | | * | ACPI: Use struct dev_pm_ops for power management in processor driverRafael J. Wysocki2012-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make the ACPI processor driver define its PM callbacks through a struct dev_pm_ops object rather than by using legacy PM hooks in struct acpi_device_ops. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
| | | * | ACPI / PM: Drop pm_message_t argument from device suspend callbackRafael J. Wysocki2012-07-01
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | None of the drivers implementing the ACPI device suspend callback uses the pm_message_t argument of it, so this argument may be dropped entirely from that callback. This will simplify switching the ACPI bus type to PM handling based on struct dev_pm_ops. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

* | / ACPI: delete _GTS/_BFS supportLen Brown2012-07-30
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _GTS and _BFS were added to the suspend/resume flow in the ACPI 2.0 specification. Linux dutifully implemented _GTS and _BFS. We discovered that it was rarely seen in systems in the field. Further, some of those systems had AML so bogus that it could never work -- proof that no other operating system supports _GTS and _BFS. So we made _GTS and _BFS optional via modparam, and disabled them by default. But we've had to complicate some code to keep this support in the kernel, as these methods are defined to be evaluated very close to sleep entry and exit. Indeed, no other AML is ever evaluated with interrupts off. We have submitted a proposal for _GTS and _BFS to be officially removed from the ACPI specification on the next revision. Here we remove it from Linux. Signed-off-by: Len Brown <len.brown@intel.com> Acked-by: Ingo Molnar <mingo@kernel.org> Acked-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

| | | * ACPI: Add _OST support for sysfs ejectToshi Kani2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changed acpi_bus_hot_remove_device() to support _OST. This function is also changed to global so that it can be called from hotplug notify handlers to perform hot-remove operation. Changed acpi_eject_store(), which is the sysfs eject handler. It checks eject_pending to see if the request was originated from ACPI eject notification. If not, it calls _OST(0x103,84,) per Figure 6-37 in ACPI 5.0 spec. Added eject_pending bit to acpi_device_flags. This bit is set when the kernel has received an ACPI eject notification, but does not initiate its hot-remove operation by itself. Added struct acpi_eject_event. This structure is used to pass extended information to acpi_bus_hot_remove_device(), which has a single argument to support asynchronous call Signed-off-by: Toshi Kani <toshi.kani@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
| | | * ACPI: Add an interface to evaluate _OSTToshi Kani2012-06-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added acpi_evaluate_hotplug_opt(). All ACPI hotplug handlers must call this function when evaluating _OST for hotplug operations. If the platform does not support _OST, this function returns AE_NOT_FOUND and has no effect on the platform. ACPI_HOTPLUG_OST is defined when all relevant ACPI hotplug operations, such as CPU, memory and container hotplug, are enabled. This assures consistent behavior among the hotplug operations with regarding the _OST support. When ACPI_HOTPLUG_OST is not defined, this function is a no-op. ACPI PCI hotplug is not enhanced to support _OST at this time since it is a legacy method being replaced by PCIe native hotplug. _OST support for ACPI PCI hotplug may be added in future if necessary. Some platforms may require the OS to support _OST in order to support ACPI hotplug operations. For example, if a platform has the management console where user can request a hotplug operation from, this _OST support would be required for the management console to show the result of the hotplug request to user. Added macro definitions of _OST source events and status codes. Also renamed OSC_SB_CPUHP_OST_SUPPORT to OSC_SB_HOTPLUG_OST_SUPPORT since this _OSC bit is not specific to CPU hotplug. This bit is defined in Table 6-147 of ACPI 5.0 as follows. Bits: 3 Field Name: Insertion / Ejection _OST Processing Support Definition: This bit is set if OSPM will evaluate the _OST object defined under a device when processing insertion and ejection source event codes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This interface allows the host to override a table via a physical address, instead of the logical address required by acpi_os_table_override. This simplifies the host implementation. Initial implementation by Thomas Renninger. ACPICA implementation creates a single function for table overrides that attempts both a logical and a physical override.

| * | | ACPICA: Expand OSL memory read/write interfaces to 64 bitsBob Moore2012-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change expands acpi_os_read_memory and acpi_os_write_memory to a full 64 bits. This allows 64 bit transfers via the acpi_read and acpi_write interfaces. Note: The internal acpi_hw_read and acpi_hw_write interfaces remain at 32 bits, because 64 bits is not needed to access the standard ACPI registers.

| * | | ACPI, APEI: Add 64-bit read/write support for APEI on i386Myron Stowe2012-01-21

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.
