[Intel-gfx] [PATCH 2/4] drm/i915: Disable PSR2 while getting pipe CRC

2019-02-13 Thread José Roberto de Souza
As stated in CRC_CTL spec, after PSR entry state CRC will not be calculated anymore what is not a problem as IGT tests do some screen change and then request the pipe CRC right after the change so PSR will go to idle state and only will entry again after at least 6 idles frames. But for PSR2 it is
