From 5066f7cd0e010db46b42f8f08a33c10cb34f8726 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Fri, 6 May 2011 08:40:08 +1000 Subject: [PATCH] r600g: add rv670 flushing workaround. Hopefully we can find out the proper fix for this, but for now this makes the fbo mipmap tests pass on my rv670 (x2 card).
