From: Rob Clark Date: Sun, 22 Jan 2017 17:23:27 +0000 (-0500) Subject: freedreno/a5xx: set fragcoordxy properly X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8d6af93e76bb9e592293b632b22b2b756cc0cae8;p=mesa.git freedreno/a5xx: set fragcoordxy properly What a3xx docs call IJPERSPCENTERREGID.. the xy coord passed into bary.f. We were incorrectly setting both this and gl_FragCoord.xy to the same register resulting in all sorts of hilarity. Fixes stk, vdrift, 0ad, probably a bunch others.
