Author: Kenneth Graunke <[email protected]> Date: Tue May 10 17:54:45 2016 -0700 i965: Drop perf_debug about rasterizer discard in SOL vs. clipper. I recently experimented with performing rasterizer discard in the SOL unit instead of the clipper, and as far as I can tell, it's basically the same performance. The clipper comes directly after SOL anyway, and setting the clipper to REJECT_ALL should be pretty darn cheap. Keep the perf_debug on Sandybridge, where the GS actually does work.
