This bug is awaiting verification that the linux-mtk/5.15.0-1030.34
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-jammy-linux-mtk' to 'verification-done-jammy-
linux-mtk'. If the problem still exists, change the tag 'verification-
needed-jammy-linux-mtk' to 'verification-failed-jammy-linux-mtk'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
  [Impact]

  During AMD Genoa development, the datacenter team identified
  performance regressions that were root caused in the amd-pstate
  driver. A first round of fixes already landed upstream (v6.1-rc7) in
  the amd-pstate driver, and should be backported to all the affected
  kernels.

  [Fix]

  Backport the upstream amd-pstate fixes:

  [Regression potential]

  Clean cherry-picks of already upstream (v6.1-rc7) fixes, impact a
  single driver (amd-pstate) and the new mode (passive) is disabled by
  default.
