Bug description:
[Impact]
AMD RN and CZN SOC can collect extra debugging data for s0i3. This
information is useful for finding problems with IP blocks not going into
correct states.
[Fix]
The following patch series adds support for these stats and will be included
in 5.14.
https://patchwork.kernel.org/project/platform-driver-x86/patch/[email protected]/
[Test]
Check for extra debugfs files on amd platform. Verify that s0i3 shows
successful enter (counter increases to non-zero).
[Where problems could occur]
The code is only used on amd platforms in s2idle. It would be specific to
those platforms and cases (where it is adding support for debugging).
