[Intel-gfx] [PATCH 021/190] drm/i915: Use HWS for seqno tracking everywhere
Chris Wilson
chris at chris-wilson.co.uk
Mon Jan 11 01:16:32 PST 2016
By using the same address for storing the HWS on every platform, we can
remove the platform specific vfuncs and reduce the get-seqno routine to
a single read of a cached memory location.
