I'm seeing some weird intermittent bugs (vm faults, hangs, etc) when
trying to use amdgpu_job_submit_direct. I'm wondering if there is a
possibility of a race condition, when a submit_direct and a GPU
scheduler thread try to submit to the same ring at the same time. I
didn't see any locking to allow multiple threads safely submitting to
the same ring.
Am I missing something?
Thanks,
Felix
