TTM has a device struct per device and an optional global struct that is common for all devices and intended to be per subsystem.

The only subsystem currently having a global structure is the memory accounting subsystem:
struct ttm_mem_global

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.
Jerome,
This is exactly what the current code intends to do.

Are you seeing something different?
