Revision 400dd489d42faef3647d990dd67f553371ec204b authored by Ian Rogers on 15 December 2022, 06:55:02 UTC, committed by Arnaldo Carvalho de Melo on 21 December 2022, 17:52:41 UTC
Update the sapphirerapids metrics and events using the new tooling from: https://github.com/intel/perfmon The metrics are unchanged but the formulas differ due to parentheses, use of exponents and removal of redundant operations like "* 1". The order of metrics varies as TMA metrics are first converted and then removed if perfmon versions are found. The events are updated to 1.09, in particular uncore, with fixes to uncore events and improved descriptions. The formatting changes increase consistency across the json files.
