AMD Zen2/3 support should be in papi-5.6.0-16.el8. @mkolar could you check the proposed z-stream rpms in the scratch builds and verify that they fufill comment #6: 7. Prepare a RHEL rpm scratch build and have this change validated on the latest RHEL milestone compose by someone other than the developer. A comment must be added to the Bugzilla indicating the validation is successful and there were no observed regressions. Working on it. (In reply to William Cohen from comment #8) @wcohen no regression was observed during testing of the proposed scratch builds. @fandrieu could you provide an OtherQA flag since the customer is able to help with testing? I reserved a zen3 machine Friday in beaker and tried out the libpfm and papi and compared to the existing rhel8.6 rpms the results were definitely better. @lkuprova, you tested on zen2/3 so we don't need the OtherQA? Is that correct? (In reply to William Cohen from comment #18) > @lkuprova, you tested on zen2/3 so we don't need the OtherQA? Is > that correct? Yes, I tested it on both Zen 2 and Zen 3 systems. I consider OtherQA only a nice-to-have. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
