[Intel-gfx] [PATCH 3/6] drm/i915/fbc: Move the plane state check into the fbc functions
Ville Syrjala

Fri Dec 13 13:34:50 UTC 2019
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Instead of dealing with the presence/absence of the primary
plane in the higher level pre/post plane update code let's
move all that into the fbc code itself. Now the higher level
code doesn't have to think about FBC details anymore.
