ACPI: Fix D3hot v D3cold confusion

2012-05-05T05:19:52Z

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 Acked-by: Rafael J.

ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFS

2012-03-27T01:16:25Z

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.

ACPI: Drop ACPI_NO_HARDWARE_INIT

2011-11-07T01:32:31Z

ACPI_NO_HARDWARE_INIT is only used by acpi_early_init() and acpi_bus_init() when calling acpi_enable_subsystem(), but acpi_enable_subsystem() doesn't check that flag, so it can be dropped. Signed-off-by: Rafael J. Wysocki Signed-off-by: Len Brown

ACPI: Add D3 cold state

2011-05-29T06:21:08Z

_SxW returns an Integer containing the lowest D-state supported in state Sx. If OSPM has not indicated that it supports _PR3, then the value “3” corresponds to D3. If it has indicated _PR3 support, the value “3” represents D3hot and the value “4” represents D3cold. Linux does set _OSC._PR3, so we should fix it to expect that _SxW can return 4.

ACPICA: Execute an orphan _REG method under the EC device

2011-05-10T02:16:12Z

This change will force the execution of a _REG method underneath the EC device even if there is no corresponding operation region of type EmbeddedControl. Fixes a problem seen on some machines and apparently is compatible with Windows behavior. http://www.acpica.org/bugzilla/show_bug.cgi?id=875 Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown
