[Intel-gfx] [PATCH v2 16/20] drm/i915: Move pipe ddb entries into the dbuf state
Ville Syrjala

Tue Feb 25 17:11:21 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
The dbuf state will be where we collect all the inter-pipe dbuf
allocation stuff. Start by moving the actual per-pipe ddb entries
there.
