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.
Thierry

... 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.

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

I came up with something very similar by splitting up nouveau_bo_new()
into allocation and initialization steps, so that when necessary the GEM
object can be initialized in between. I think that's slightly more
flexible and easier to understand than a boolean flag.

Subject: [PATCH] drm/nouveau: Initialize GEM object before TTM object
TTM assumes that drivers initialize the embedded GEM object before
calling the ttm_bo_init() function. This is not currently the case
in the Nouveau driver. Fix this by splitting up nouveau_bo_new()
into nouveau_bo_alloc() and nouveau_bo_init() so that the GEM can
be initialized before TTM BO initialization when necessary.
Fixes: b96f3e7c8069 ("drm/ttm: use gem vma_node")

Yes, that should work too.
