[PATCH 2/7] drm/i915: Expose alpha formats on VLV/CHV primary planes

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Currently we expose VLV/CHV alpha blending only on the sprite
planes, but the primary planes can do it as well. Let's flip
it on.

v2: Rebase due to fp16 landing
