Description William Cohen 2023-04-10 18:35:37 UTC 
libpfm-4.13.0 (https://perfmon2.sourceforge.net/) is out and would address the various RHEL hardware enablement bugs filed.
Comment 5 William Cohen 2023-07-28 15:46:01 UTC 
Have a little blurb in doc text listing the microarchitectures supported.  Feel free to tweak it to match the standards.  Intel will probably also want sapphire rapids changed to whatever the marketing name is.  Note that rhel8 did have zen2/3 support backported, but rhel9.2 didn't have AMD zen2/3 support so those are added to the rhel9 doc text.
