GPU hangs when encoding simultaneously a HEVC (444-8 bits stream) and a H264 (420-8 bits stream) .

In Linux, running simultaneously a HEVC 444-8 bits encoding with another H264 420-8 bits encoding, causes a GPU hang.

i915 kernel messages:

i915 0000:00:02.0: [drm] Resetting vcs0 for preemption time out
i915 0000:00:02.0: [drm] sample_encode[142482] context reset due to GPU hang
i915 0000:00:02.0: [drm] GPU HANG: ecode 12:4:28ffff7d, in sample_encode [142482]


Steps to repro:
- Get an input AYUV raw file, and another input NV12 file raw.
- Repro command line using the sample_encode app:

sample_encode h265 -vaapi -hw -qsv-ff -async 4 -pp -g 60 -r 1 -f 60 -perf_opt 32 -n 20000 -vbr -b 5000 -ayuv -i ./AYUV_1080p.yuv -w 1920 -h 1080 -o /dev/null & sample_encode h264 -vaapi -hw -qsv-ff -async 4 -pp -g 60 -r 1 -f 60 -perf_opt 32 -n 20000 -vbr -b 5000 -nv12 -i ./NV12_1080p.yuv -w 1920 -h 1080 -o /dev/null

Hi,

 

Good day to you.

 

Thank you for posting in Intel communities.

 

We were able to reproduce your issue from our end on latest version of VPL (2023.4.0) and 12th Gen Intel(R) Core(TM) i9-12900K.

We could observe that while running AYUV, it is showing as unsupported as in the screenshot below.
