Bug Description
[Impact]
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.
cd linux-firmware
sudo make install
sudo update-initramfs -c -k all
[Fix]
Update amdgpu/
[Test Case]
See original description.
[Where Problems Could Occur]
Isolated to AMD GPUs that use dimgrey_cavefish firmware blobs.
[Original Description]
Kernel: 5.15.0-43-generic
linux-firmware: 20220329.
Tested with: Mint 21 Cinnamon (Ubuntu 22.04 based)

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.
