From 6271901d828b34b27607314026deaf417f9f9b75 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 19 Feb 2010 16:07:02 -0500 Subject: [PATCH] drm/radeon/rv740: fix backend setup This patch fixes occlusion queries and rendering errors on rv740 boards. Hardcoding the backend map is not an optimal solution, but a better fix is being worked on.
