From bba9852feedf3d38f963278e07bdd3db622090b9 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Thu, 14 Feb 2013 09:37:35 +1000 Subject: [PATCH] drm/nv84-/fence: abstract class emit/sync functions to virt+sequence Now can be used to operate on any buffer mapped into the GPU virtual address and not just the main inter-channel sync buffer.
