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/20210629084803.248498-2-shyam-sundar....@amd.com/ [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).
