[Bug 2058330] Re: Update amd-pmf for AMD strix series

This bug is awaiting verification that the linux-oem-6.8/6.8.0-1006.6
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-noble-linux-oem-6.8' to 'verification-done-
noble-linux-oem-6.8'. If the problem still exists, change the tag
'verification-needed-noble-linux-oem-6.8' to 'verification-failed-noble-
linux-oem-6.8'.


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:
[SRU Justfication]

[Impact]

Missing AMD-PMF support for AMD Strix platforms.

[Fix]

A few commits from v6.9-rc1.

[Test Case]

And feature enabled message should appear in dmesg:

[ 3.203628] amd-pmf AMDI0103:00: registered PMF device successfully

Access via sysfs:

root@test:/sys/devices/platform/AMDI0103:00# cat cnqf_enable
on

[Where problems could occur]

PMF once caused cpufreq locks or other unexpected behaviors in the
past and may take additional fix to address.

[Other Info]

While this is in v6.9-rc-1 now, Noble and OEM-6.8 will be nominated
for fix.
