From 4e5e2e2560aa1d1d01f7af97af2f72706f61da27 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Sat, 18 Feb 2006 15:51:35 +1100 Subject: drm: radeon add r300 TX_CNTL and verify bitblt packets The Xgl on r300 doesn't work unless you add a verify bitblt function to the DRM, and we need to pass TX_CNTL to flush texture caches.
