From: Ilia Mirkin Date: Fri, 20 Nov 2015 23:11:26 +0000 (-0500) Subject: freedreno/a4xx: point regid to "red" even for alpha-only rb formats X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ff9450ecd1f7635f8917e3177f0ef18eb8f9f49b;p=mesa.git freedreno/a4xx: point regid to "red" even for alpha-only rb formats Looks like a4xx hw does this in a more standard way and we don't need to hack around it like we do on a3xx. Fixes GL_ALPHA formats in fbo-blending-formats, fbo-colormask-formats, and fbo-alphatest-formats.
