From f2f9a2cbaf019481feefe231f996d3602612fa99 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Wed, 1 Oct 2014 12:46:14 +1000 Subject: [PATCH] drm/nouveau: fix regression on original nv50 board Xorg (and any non-DRM client really) doesn't have permission to directly touch VRAM on nv50 and up, which the fence code prior to g84 depends on. It's less invasive to temporarily grant it premission to do so, as it previously did, than it is to rework fencenv50 to use the VM. That will come later on.
