<content type='text'>
Once command submission failed due to userptr invalidation in
amdgpu_cs_submit, legacy code will perform cleanup of scheduler
job. However, it's not needed at all, as former commit has integrated
job cleanup stuff into amdgpu_job_free. Otherwise, because of double
free, a NULL pointer dereference will occur in such scenario.

<id>682439fffad9fa9a38d37dd1b1318e9374232213</id>
<content type='text'>
[Why]
Reading pipe_fuses from register may have invalid bits set, which may
 affect the num_pipes erroneously.

[How]
Add read_pipes_fuses() call and filter bits based on expected number
 of pipes.

<title>drm/amdgpu: disable SDMA WPTR_POLL_ENABLE for SR-IOV</title>

<id>100bd00881f8553d0ccfc99a575966d990c455eb</id>
<content type='text'>
[Why]
This WPTR_POLL_ENABLE is a hardware contigious polling which will cause
FCLK and UCLK to keep on a high level.
Mostly its case can be covered by F32_WPTR_POLL_ENABLE which polls by
firmware.
So to save power, SR-IOV also needs to disable this bit
