Bug Description

Feature: Correct uPEP support for all current ACPI _HID for AMD s2idle
Code:

Currently oem-5.10 carries hack ""platform/x86: force LPS0 functions for AMD"" which helps some RN platforms, but is not the correct solution.

The code that is the correct solution has been submitted to linux-acpi:
https://<email address hidden>/T/#t

This will fix RN properly and will also add support for the different variations used for CZN for uPEP.

Please replace hack in oem-5.10, and also apply this series for oem-5.13.

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!
