[PATCH v6 08/17] drm/ttm: use gem vma_node

Drop vma_node from ttm_buffer_object, use the gem struct
(base.vma_node) instead.

Hi Gerd,

I've been seeing a regression on Nouveau with recent linux-next releases
and git bisect points at this commit as the first bad one. If I revert
it (there's a tiny conflict with a patch that was merged subsequently),
things are back to normal.

I think the reason for this issue is that Nouveau doesn't use GEM
objects for all buffer objects, and even when it uses GEM objects, the
code will not initialize the GEM object until after the buffer objects
and the backing TTM objects have been created.

I tried to fix that by making sure drm_gem_object_init() gets called by
Nouveau before ttm_bo_init(), but the changes are fairly involved and I
was unable to get the GEM reference counting right. I can look into the
proper fix some more, but it might be worth reverting this patch for
now to get Nouveau working again.

[Nouveau] [Intel-gfx] [PATCH v6 08/17] drm/ttm: use gem vma_node

> Hi Gerd,

... but the initialization order is.

ttm_bo_uses_embedded_gem_object() assumes gem gets initialized first.

drm_gem_object_init() init calling drm_vma_node_reset() again is
probably the root cause for the breakage.
> I tried to fix that by making sure drm_gem_object_init() gets called by

Changing the order doesn't look hard.  Patch attached (untested, have no
test hardware).  But maybe I missed some detail ...

The other patch attached works around the issue with a flag, to avoid
drm_vma_node_reset() being called twice.

cheers,
  Gerd
