Ben Skeggs	ef1b287169	drm/nouveau: fix regression causing ttm to not be able to evict vram ... TTM assumes an error condition from man->func->get_node() means that something went horribly wrong, and causes it to bail. The driver is supposed to return 0, and leave mm_node == NULL to signal that it couldn't allocate any memory.

Ben Skeggs	573a2a37e8	drm/nv50: implement custom vram mm ... This is required on nv50 as we need to be able to have more precise control over physical VRAM allocations to avoid buffer corruption when using buffers of mixed memory types. This removes some nasty overallocation/alignment that we were previously using to "control" this problem. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>	2010-12-08 13:48:07 +10:00
