Subject: i965/drm: Inline brw_bo_references.
X-Git-Tag: upstream/18.1.0~7171
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5281e4ed3b2ee25627517c23708bb02857ec5992;p=platform%2Fupstream%2Fmesa.git

i965/drm: Inline brw_bo_references.

It's a single atomic add, so it makes sense to inline it.

Improves performance in Piglit's drawoverhead microbenchmark's
"DrawArrays ( 1 VBO, 0 UBO,  0    ) w/ no state change" subtest by
0.400922% +/- 0.310389% (n=350) on my i7-7700HQ.
