Ben Skeggs 6a6b73f254 drm/nouveau: add per-channel mutex, use to lock access to drm's channel ... This fixes a race condition between fbcon acceleration and TTM buffer moves. To reproduce: - start X - switch to vt and "while (true); do dmesg; done" - switch to another vt and "sleep 2 && cat /path/to/debugfs/dri/0/evict_vram" - switch back to vt running dmesg We don't make use of this on any other channel yet, they're currently protected by drm_global_mutex. This will change in the near future. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>		2010-12-03 15:05:10 +10:00
