I am disabling governors as soon as we start suspend. So No, cpufreq wouldn't
work during suspend/resume. But once system is resumed we are starting it back
again.
Hibernation is probably not supported by my code yet.. I just went through
hibernation code quickly and it looks we don't send PM_SUSPEND_PREPARE or
PM_POST_SUSPEND notifications in case of hibernation. Correct?
And these are the notifications that we send:
- PM_HIBERNATION_PREPARE
- PM_POST_HIBERNATION
- PM_RESTORE_PREPARE
- PM_POST_RESTORE
If I am not wrong I need to stop governors on PM_HIBERNATION_PREPARE and need to
start them back on: PM_POST_HIBERNATION (I am a bit confused with this one. Does
this POST_HIBERNATION one happens at the end of going into hibernation? or after
booting back? I need a notifier at the end of restore)..
