[Bug 2137615] Re: [SRU] add pmc c6 support of Arrow Lake

This bug is awaiting verification that the linux-intel/6.17.0-1008.8
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-questing-linux-intel' to 'verification-done-
questing-linux-intel'. If the problem still exists, change the tag
'verification-needed-questing-linux-intel' to 'verification-failed-
questing-linux-intel'.


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]
The error is shown in dmesg:
kernel: intel_pmc_core INT33A1:00: pmc_core: couldn't get DMU telem endpoint -6
c6 status is not shown in debugfs.

[Fix]
Add Arrow Lake PMU GUIDs in pmc_core:
a32f7d76e3cd7 platform/x86:intel/pmc: Add DMU GUID to Arrow Lake U/H
3b603955f2423 platform/x86:intel/pmc: Add support for multiple DMU GUIDs
644ab3bc98ee3 platform/x86:intel/pmc: Update Arrow Lake telemetry GUID

[Test]
The pmc error is not shown in dmesg.
# cat /sys/kernel/debug/pmc_core/die_c6_us_show
16476381

[Where problems could occur]
It may break intel pmc support.

Noble 6.8 kernel got some conflicts and need many commits and revert.
So SRU for questing, oem-6.17 and resolute.
