[Intel-gfx] [PATCH 1/8] drm/i915: Make own struct for execlist items
Mika Kuoppala
mika.kuoppala at linux.intel.com
Tue Sep 12 08:36:11 UTC 2017
Engine's execlist related items have been increasing to
a point where a separate struct is warranted. Carve execlist
specific items to a dedicated struct to add clarity.
v2: add kerneldoc and fix whitespace (Joonas, Chris)
