2012-03-27ACPICA: Sleep/Wake interfaces: optionally execute _GTS and _BFSLin Ming1-6/+15
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.

2012-03-22ACPICA: Clarify METHOD_NAME* defines for full-pathname casesBob Moore1-11/+11
Changed the METHOD_NAME* defines that define a full pathname to the method to METHOD_PATHNAME* in order to make it clear that it is not a simple 4-character ACPI name. Used for the various sleep/wake methods. Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2012-03-22ACPICA: Split sleep/wake functions into two filesBob Moore1-0/+251
The functions for the original/legacy sleep/wake registers are in hwsleep.c, and the functions for the new extended FADT V5 sleep registers are in hwesleep.c Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
