From 147666fb3b93b8c484f562da33a37f886ddff768 Mon Sep 17 00:00:00 2001 From: Thomas Hellstrom Date: Wed, 17 Nov 2010 12:38:32 +0000 Subject: [PATCH] drm/radeon: Use the ttm execbuf utilities Rather than re-implementing in the Radeon driver, Use the execbuf / cs / pushbuf utilities that comes with TTM. This comes with an even greater benefit now that many spinlocks have been optimized away...
