From f56cb86f9abd229418f894a8ffedfb9ff465c181 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 8 Jul 2010 11:29:10 +1000 Subject: drm/nouveau: add instmem flush() hook This removes the previous prepare_access() and finish_access() hooks, and replaces it with a much simpler flush() hook. All the chipset-specific code before nv50 has its use removed completely, as it's not required there at all.
