From the design it looks good to me, but I really don't know much about
XGMI.
When you want to simplify it a bit, I'm pretty sure the calls to
ttm_bo_lock_delayed_workqueue()/ttm_bo_unlock_delayed_workqueue() can
just be dropped.
They are copy & pasted over from radeon and on amdgpu there isn't any
reason for that any more.
