[Intel-gfx] [PATCH 067/190] drm/i915: Unify legacy/execlists emission of MI_BATCHBUFFER_START
Chris Wilson
chris at chris-wilson.co.uk
Mon Jan 11 01:17:18 PST 2016
Both the ->dispatch_execbuffer and ->emit_bb_start callbacks do exactly
the same thing, add MI_BATCHBUFFER_START to the request's ringbuffer -
we need only one vfunc.
