Bug description:
[SRU Justification]
[Impact]
There is no way to access information under /sys/kernel/debug/pmc_core
on Comet Lake platforms.
[Fix]
* https://lkml.org/lkml/2019/11/18/713 ("platform/x86: intel_pmc_core: Add
Comet
Lake (CML) platform support to intel_pmc_core driver")
[Test Case]
1. install prebuilt kernels from ppa:vicamo/ppa-1847450
2. boot with installed kernel and check if /sys/kernel/debug/pmc_core is
then available.
[Regression Potential]
Low. This only adds two new IDs to a model white list and doesn't change
behavior of existing systems.
