The current GPE code attempts to define GPEs as either runtime (the default), wake or run/wake. These states are orthogonal to whether or not a GPE is actually enabled or not. Further, various additional flags are defined and set, but never used. This architecture is additionally complicated by changing the type of a GPE causing it to be disabled, resulting in complex functions that then have to conditionally re-enable a GPE. It also makes it impossible to determine how many consumers a given GPE has, preventing us from being able to implement runtime power management for devices requiring GPEs for wakeup notification. This patchset adds a new, simpler API and transitions the existing users over to it. It then removes the old code. drivers/acpi/acpica/acevents.h | 6 - drivers/acpi/acpica/aclocal.h | 2 drivers/acpi/acpica/evgpe.c | 150 ++++--------------------------------- drivers/acpi/acpica/evgpeblk.c | 164 +---------------------------------------- drivers/acpi/acpica/evxface.c | 14 --- drivers/acpi/acpica/evxfevnt.c | 139 ++++++++++++++++++++++++++++++++-- drivers/acpi/button.c | 18 +++- drivers/acpi/ec.c | 5 - drivers/acpi/wakeup.c | 57 +++----------- include/acpi/acpixf.h | 8 ++ include/acpi/actypes.h | 32 ++------ 11 files changed, 197 insertions(+), 398 deletions(-) -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
