Hello Ras, or anyone else affected,

Accepted linux-firmware into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/linux-
firmware/20220329.git681281e4-0ubuntu3.5 in a few hours, and then in the
-proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in

Title:
  Linux Firmware drops AMD RX6650 XT Performance

Status in linux-firmware package in Ubuntu:
  Invalid
Status in linux-firmware source package in Jammy:
  Fix Committed

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.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
  cd linux-firmware
  sudo make install
  sudo update-initramfs -c -k all

  [Fix]

  Update amdgpu/dimgrey_cavefish_* firmware files to latest versions
  from kernel.org.

  [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.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.
