Title:
Linux Firmware drops AMD RX6650 XT Performance
Status in linux-firmware package in Ubuntu:
Invalid
Status in linux-firmware source package in Jammy:
Triaged
Bug description:
Kernel: 5.15.0-43-generic
linux-firmware: 20220329.git681281e4-0ubuntu3.3
Tested with: Mint 21 Cinnamon (Ubuntu 22.04 based)
In e.g. the Unigine benchmark, the linux-firmware packages drops the
performance of my AMD RX 6650 XT GPU from 98 FPS in 1080p-high down to
23 FPS. That wasn't a problem in Mint 20.3 with kernel 5.15 (Ubuntu
20.04 based).
Getting the firmware directly from git brings the performance back to about
100 FPS:
git clone
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
sudo make install
sudo update-initramfs -c -k all
Re-installing the linux-firmware package causes the performance to
drop again. So there is a problem with the linux firmware at least for
the RX 6650 XT, maybe for the whole RX 6000 series.
The linux-firmware package in Ubuntu 22.04 should be updated.
