[PATCH v4 01/19] drm: Add |struct drm_gem_vram_object| and helpers
...call that function?
Something like this:
drm_gem_vram_push_to_system()
{
if (gbo->pin_count == 1 && gbo->kmap.virtual)
ttm_bo_kunmap(&gbo->kmap);
return drm_gem_vram_unpin();
}
> +struct drm_gem_vram_object {
> + /* Supported placements are %TTM_PL_VRAM and %TTM_PL_SYSTEM */
> + struct ttm_placement placement;
> + struct ttm_place placements[3];
placements[2] should be enough I guess?

Moving LRU handling into Nouveau v2
Hi guys,
I already tried this a few month ago, but since I don't have NVidia hardware its rather hard to test for me (need to get some ordered).
Dave brought up the topic that we should probably try to move the handling into Nouveau once more, so I tried to fix the problem Ben reported and rebased on top of current drm-misc-next.
Dave can you test this? At least in theory the approach

[PATCH] drm/nouveau: fix TTM_PL_TT memtype on pre-nv50
Commit a55409066 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU
access") made it possible to work with tiled memory. However
mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a
drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the
untiled check to explicitly include all pre-nv50 cards.

The function is only used by ast and mgag200 framebuffer handling. It's
actually something that should be done by VRAM MM, but both drivers are
non-atomic and could require an overhaul anyway.

TTM/Nouveau cleanups
Hi guys,
I've already send this out in September last year, but only got a response from Daniel.
Could you guys please test this and tell me what you think about it?
Basically I'm trying to remove all driver specific features from TTM which don't need to be inside the framework.
Thanks,
Christian.
