[RFC PATCH 0/2] add direct IB pool

[xinhui pan]

druing gpu recovery, we alloc ibs for ring tests to test if recovery
succeed or not.

As gpu recovery parked the gpu scheduler thread, any pending jobs hold the ib
resource has no chance to free. So the ring test above got stuck if no
ib to alloc.

If we schedule IBs directly in job_submit_direct, we can alloc ibs in
the new ib pool. It should have less contention.

If the IB could be freed in time, IOW, not depending on any scheduler,
nor any other blocking code. It is better to alloc ibs in direct pool.

  drm/amdgpu: add direct ib pool
  drm/amdgpu: use new job alloc variation if possible
