drm/ttm: fix caching problem on non-PAT systems.

2010-02-19T21:30:15+00:00

http://bugzilla.kernel.org/show_bug.cgi?id=15328

This fixes a serious regression on AGP/non-PAT systems, where
pages were ending up in the wrong state and slowing down the
whole system.

[airlied: taken this from the bug as the other option is to revert
the change which caused it].

drm/ttm: Fix a bug occuring when validating a buffer object in a range.

2010-02-15T01:19:14+00:00

If the buffer object was already in the requested memory type, but
outside of the requested range it was never moved into the requested range.

drm/ttm: remove padding from ttm_ref_object on 64bit builds

2010-02-01T01:24:50+00:00

Re-order structure ttm_ref_object to remove 8 bytes of alignment padding
on 64 bit builds, so shrinking its size from 72 to 64 bytes allowing it
to fit into a smaller slab.

drm/ttm: Fix race condition in ttm_bo_delayed_delete (v3, final)

2010-01-25T01:43:54+00:00

Resending this with Thomas Hellstrom's signoff for merging into 2.6.33

ttm_bo_delayed_delete has a race condition, because after we do:
kref_put(&nentry->list_kref, ttm_bo_release_list);

we are not holding the list lock and not holding any reference to
objects, and thus every bo in the list can be removed and freed at
this point.

However, we then use the next pointer we stored, which is not guaranteed
to be valid.

This was apparently the cause of some Nouveau oopses I experienced.

This patch rewrites the function so that it keeps the reference to nentry
until nentry itself is freed and we already got a reference to nentry->next.

v2 updated by me according to Thomas Hellstrom's feedback.
v3 proposed by Thomas Hellstrom. Commit comment updated by me.

Both updates fixed minor efficiency/style issues only and all three versions
should be correct.

drm/ttm: Make sure system buffer objects has offset == 0.

This is a convention that the vmwgfx driver has come to rely on.
