    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
