From 2703c21a82301f5c31ba5679e2d56422bd4cd404 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 1 Apr 2011 09:50:18 +1000 Subject: drm/nv50/gr: move to exec engine interfaces This needs a massive cleanup, but to catch bugs from the interface changes vs the engine code cleanup, this will be done later.
