[PATCH 06/13] drm/i915/fbc: Track plane visibility

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Currently the code (ab)uses cache->vma to indicate the plane
visibility. I want to nuke that so let's add a dedicated boolean
for this.
