2018-12-07T22:53:47Z

amdgpu_ring_soft_recovery would have Call-Trace, when s_fence->parent was NULL inside amdgpu_job_timedout. Check fence first, as drm_sched_hw_job_reset did. Signed-off-by: Wentao Lou Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: further ring test cleanups

2018-11-05T19:21:25Z

Move all error messages from IP specific code into the common helper. This way we now uses the ring name in the messages instead of the index and note which device is affected as well. Also cleanup error handling in the IP specific code and consequently use ETIMEDOUT when the ring test timed out.
