From 0cdd82df53a55907b311ede0e80c3ce2fb37f287 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 31 May 2011 15:33:07 +1000 Subject: [PATCH] r600g: add context control to start of CS On my original R600 card this at least lets gnome shell run for a while longer and the piglit r300-readcache test case works a lot more reliably. Still a few more stability issues running a piglit test run though.
