Hi,
I need a urgent help regarding this below situation.
As per my understanding when even OS initiated Shutdown or Reboot, it must process through _TTS, _PTS, _GTS like ACPI control method, which helps BIOS also to do some stuffs in order to handle some condition. But in Win8 I become wondered when I saw OS initiated
Shutdown or Reboot process but didn't call _TTS method that I have written in my ACPI code to handle some condition before OS inform its native drivers about Sleep state. But I saw _PTS method gets call.
Can you please let me know does it is expected behavior in Win8 shutdown or reboot or its my mistake in understanding the flow.
If I'm right I would also like to know, is there any mechanism available in BIOS(ACPI) side (similar to _TTS) to be called before informing OS native driver about OS Sleep state. I want to disable some portion of ACPI code, based on OS decision
to go for Shutdown or reboot but before OS driver gets called.
Thanks,
Subrata
