Bug Description

[SRU Justification]

[Impact]

Missing driver for pmc_core on Intel Alder Lake platforms.

[Fix]

https://patchwork.kernel.org/project<email address hidden>/

[Test Case]

$ ls /sys/bus/platform/drivers/intel_pmc_core
...
INT33A1:00

[Where problems could occur]

This adds driver support for a new platform. No regression by the
definition can happen, but it may still suffer from incompleteness of
userspace utility support.

[Other Info]

Alder Lake targets 5.13 kernels, so only Impish & oem-5.13 is proposed.

========== original bug description ==========

[Summary]
intel_pmc_core driver is not probed

[Reproduce Steps]
1. $ ls /sys/bus/platform/drivers/intel_pmc_core
2. No INT33A1:00 device under the directory

[Results]
Expected: INT33A1:00 device is shown in the intel_pmc_core directory
Actual: No device probed by intel_pmc_core successfully

This bug is awaiting verification that the 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-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

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!

Is this going to be backported to the generic/generic-hwe kernels?

Roland, we're not going to backport since current generic kernels don't support Alder Lake.
