Hi Thomas,
[moving vger to bcc]
mhm, sounds like something isn't running in parallel any more.
We usually don't test the multimedia engines for this but we do test
gfx+compute, so I'm really wondering what goes wrong here.
Could you run some tests for me? Additional to that I'm going to raise
that issue with our multimedia guys later today.
Yes, I can run some tests for you. Which tests?
Try this as root:
echo 1 > /sys/kernel/debug/tracing/events/dma_fence/dma_fence_init/enable
echo 1 > /sys/kernel/debug/tracing/events/dma_fence/dma_fence_signaled/enable
cat /sys/kernel/debug/tracing/trace_pipe > trace.log
Then start the encoding in another shell, after it completed cancel the cat
with cntr+c and save the log file.
Do this one with the old kernel and once with the new one.
https://32h.de/tv/5.18.0-i5-trace.log.bz2
https://32h.de/tv/5.19.0-rc3-i5-trace.log.bz2
I hope I have done this correctly.
All necessary tracing things switched on?
I want to add that this is a headless machine. No monitor connected.
