[igt-dev] [RFC 0/1] PSR H/W tracking validation

[Anshuman Gupta]

PSR i915 driver implementation exposes PSR IIR interrupts'
ktime last_entry_attempt, last_exit.

PSR H/W IGT assumes that last_entry_attempt and last_exit
will be increasing monotonically and uses these ktime values
to validate PSR H/W tracking with page flip events on primary
plane.

Please provide your suggestion for any improvement.
