From 550e2d9270e2f0a10c3b063899f70e4cca25fe72 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 9 Dec 2009 14:15:38 +1000 Subject: drm/radeon/kms: restore surface registers on resume. On resume on my rv530 laptop surface cntl was left disabled, so wierd stuff would happen with rendering to a tiled front buffer. This checks if the surface regs are assigned to bos and reprograms the surface registers on resume using the same path that clears them all on init.
