Hi, I've got two questions regarding the implementation of the ACPI poweroff/sleep code in drivers/acpi/sleep and drivers/acpi/hardware . 1) We don't seem to use the _TTS system-control method, although the ACPI specification (ACPI 3.0b) says that this method should be used for intiating and finishing power transitions. Could you please tell me why we don't use it? 2) In the functions acpi_enter_sleep_state_prep(), acpi_enter_sleep_state(), acpi_leave_sleep_state() we manipulate GPEs quite extensively (we disable and enable them for a couple of times during a transition), although the specification doesn't tell anything about that explicitly. Could you please explain to me what the purpose of that is?
