Thomas i don't think the way we init ttm_mem_global today make
it follow the 1 struct ttm_mem_global for everyone. I think it
should be initialized and refcounted by device struct.

So on first device creation a ttm_mem_global is created and
then anytime a new device is created the refcount of ttm_mem_global
is increased. This would mean some static global refcount inside
ttm_memory.c, maybe there is something similar to singleton in
the linux toolbox.

Thought ? Idea ?

Cheers,
Jerome
