Does this work if the console is blanked or someone just never enabled the
screen? I.e. I think we need the usual boilerplate here to make sure that
the eDP port is lit up on pipe A and dpms is ON ...

in any case source doesn't match all conditions to get PSR enabled,
igt test will skip on this:
if (!source)
igt_skip("This Hardware does not support or isn't ready for PSR\n");

Ah, I see. Still the test is a bit fragile. E.g. when the bios ever
enables PSR we won't fail the test, even when we don't enable psr. All
our other tests that check residency of power save features prepare
the system (make sure the gpu is idle for rc6, switch off all displays
for pc8+, ...). Then they grab the residency counter, sleep for a few
seconds and grab another sample of the residency counter. If it didn't
move (or in case of rc6 we expect 90%+ residency even) then the test
fails.

got your point...
I was also wondering something like that... wait a bit and get perf
counter again... then it fails if it isn't increasing...
will do that
but I more concerned right now with the fix itself otherwise psr will
never work with 3.12 :(

Check on debugfs if PSR is supported by panel and matching all conditions in
hardware. In this case PSR must be enabled and performance counting increasing
v2: check if performance counter is really increasing.
