Public bug reported: [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/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). ** Affects: linux-oem-5.10 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.13 (Ubuntu) Importance: Undecided Status: Invalid ** Affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Status: New ** Affects: linux-oem-5.13 (Ubuntu Focal) Importance: Undecided Status: New ** Tags: originate-from-1928846 ** Also affects: linux-oem-5.13 (Ubuntu) Importance: Undecided Status: New ** Also affects: linux-oem-5.10 (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: linux-oem-5.13 (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux-oem-5.10 (Ubuntu) Status: New => Invalid ** Changed in: linux-oem-5.13 (Ubuntu) Status: New => Invalid ** Tags added: originate-from-1928846 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.10 in Ubuntu. https://bugs.launchpad.net/bugs/1934809 Title: Backport support for AMD SMU statistics Status in linux-oem-5.10 package in Ubuntu: Invalid Status in linux-oem-5.13 package in Ubuntu: Invalid Status in linux-oem-5.10 source package in Focal: New Status in linux-oem-5.13 source package in Focal: New Bug description: [Impact] AMD RN and CZN SOC can collect extra debugging data for s0i3.
