KBL GT3e i915 error state
Setup:
* HW: KBL GT3e
* kernel: drm-tip git v5.2 kernel
* OS: Ubuntu 18.04
* Desktop: lightdm/Unity/compiz
* Latest MediaSDK & FFmpeg built from Git
Use-case:
* Run many parallel video encode tasks in parallel, first using FFmpeg with
VA-API backend, then using MSDK sample_multi_transcode application
Expected output:
* No hangs
Actual output:
* Last number of (recoverable) GPU hangs on rsc0 (media-driver uses compute EUs
to do some of the transcoding operations)
Notes:
* This may be media driver issue, but media driver (Github) tracker doesn't
allow attachments like i915 error state, so I though better to start from here</pre>
