Public bug reported: 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.com/kernel-firmware/linux- firmware/-/commit/977332782302476e1c863b09b840f463d0378807 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 Additional links: * https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=977332782302476e1c863b09b840f463d0378807 * 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. ** Affects: linux-firmware (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2058830 Title: vp9 hw decode broken on modern AMD apus, needs amdgpu update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/2058830/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
