Upgrade from 5.18 to 5.19 kernel breaks VAAPI video playback about intel-vaapi-driver HOT 6 CLOSED

Whatever broke this, this is no longer broken for me in 5.19.13-arch1-1

from intel-vaapi-driver.

I found this today looking around for an explanation of what I was seeing. I went to the package repos then followed upstream until I landed here and went into the issues

I am seeing this using a braswell with i965, the video is very garbled, very pixelated, I only saw the green screen once though.

Thanks for chiming in. Do you get similar errors in /var/log/messages as well? ("Resetting vecs0 for preemption time out", "GPU Hang", "Asynchronous wait on fence", etc.)

I don't see anything like that in my logs. I do see the browser throwing a bunch of errors about vsync when attempting to use hw decode. Then the entire desktop locks up for about 20 seconds while it attempts to make an image

mpv -hwdec=vaapi file

Plays the file, doesn't throw any errors, but the video output it makes is a hot mess in a way it wasn't before.

Braswell only works at all with i965

Broadwell and everything later is ihd.

Ihd wont even intialize on my machine.

I can confirm the issue is no longer broken for me either after upgrading to 5.19.13-100 (Fedora 35).

The same system update also included new Intel GPU firmware (intel-gpu-firmware-20220815-139.fc35.noarch), but reverting back to kernel 5.19.10-100 reintroduce the issue, so the problem does appear to have been fixed by the kernel+kmod combo.

Closing this issue as resolved.
