Bug description:
[Impact]
Some QHD (2560x1440) panels which support PSR2 refresh the display
abnormally. The display frequently stop responding for few seconds on all user
interactions, ex. mouse movement, TTY and any APP GUI. There's no problem on
the external monitor. After disabling PSR, the problem will be gone.
[Fix]
Intel release a fix to calculate the wake up line count and configure them
into PSR2_CTL accordingly.
[Test]
Verified on the problematic panels to check if the display responds smoothly
to mouse movement.
[Where problems could occur]
Only affects the panels on some particular panels which supports PSR2
