[PATCH 05/14] drm/i915: Plop vlv/chv fifo sizes into crtc state

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Move the vlv/chv FIFO size tracking into the crtc_state. As with the wms
for now this just acts as temporary storage.
