Bug description:
Current version of amdgpu binaries in linux-firmware shipped with
ubuntu 22.04 (jammy) and ubuntu 23.10 (mantic) create various problems
when decoding VP9 content with the iGPU on modern AMD mobile processor
(rembrant and phoenix, i.e. 6xxxU/H, 7x40U/H and 7x35U/H processor).
The issue has been reported and solved upstream:
https://gitlab.freedesktop.org/mesa/mesa/-/issues/8044
[EDIT: fixed link]
Solution dates to the end of February: https://gitlab.com/kernel-
firmware/linux-
firmware/-/commit/977332782302476e1c863b09b840f463d0378807
Ubuntu 24.04 already ships the updated binaries and should not be
affected.
Steps to reproduce:
* on an affected system play a VP9 video with hardware decoding

* https://bugzilla.redhat.com/show_bug.cgi?id=2267714
* https://www.phoronix.com/news/AMDGPU-Firmware-Fixes-VP9
Workaround:
* download the amdgpu folder from upstream linux-firmware repos
* compress each file with zstd
* copy into /lib/firmware/amdgpu
* regenerate the initrd
I'm currently running ubuntu 23.10 (mantic) with binaries from
upstream and the issue is solved.
