From ab7bd7093dfd18778ece4ed9098666c9ebc68d51 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin <imirkin@alum.mit.edu> Date: Fri, 23 May 2014 11:18:16 -0400 Subject: mesa/st: fix color outputs in presence of sample mask output MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit c5d822dad90 added support for sample mask incorrectly. It became treated as a color output, and messed up the color output indices. Revert the hunk that did that, and add explicit support just like for depth/stencil writes.
