where's the patch to enable PSR by default again? Also I've heard noises
that the sink crc stuff is busted :( And we still have the tasklist to fix
up the functional igt testcases.

I don't want to block merging this, but we need a clear task list of
what's left to do and full commitment of the necessary engineer-time to
actually make it happen. PSR with the frontbuffer tracking code is
invasive and will simply keep on bitrotting if we don't enable it (atomic
modeset already almost broke it completely by accident), which would
really be sad given all the time we've invested. Please chat with
Paul/Gavin to make sure this is tracked.

I don't want to carry essentially dead code around - the illusion that it
will get magically rebased and keep working is really just that.

Cheers, Daniel
