ACPI: delete _GTS/_BFS support

2012-07-31T01:11:25Z

_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 Acked-by: Ingo Molnar Acked-by: Konrad Rzeszutek Wilk

ACPICA: AcpiSrc: Fix some translation issues for Linux conversion

2012-07-17T04:05:51Z

Fixes issues like this: i_aSL -> iASL 00-7_f -> 00-7F local_fADT -> local_FADT execute_oSI -> execute_OSI Also, in function headers, the parameters are now translated to lower case (with underscores if necessary.) Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

ACPICA: Add support for multiple notify handlers

2012-06-01T15:51:50Z

This change adds support to allow multiple notify handlers on Device, ThermalZone, and Processor objects. Also re-worked and restructured the entire notify support code for handler installation, handler removal, notify event queuing, and notify dispatch to handler. Extends and updates original commit 3f0be67("ACPI / ACPICA: Multiple system notify handlers per device") by Rafael Wysocki. Signed-off-by: Bob Moore Signed-off-by: Lin Ming Signed-off-by: Len Brown

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.
