Oh, I did not know that perf by default may use some uncore events that are less precise than some Intel-specific events. Thanks for the info!

- soulbadguy 3y agoYou might want to look at https://icl.utk.edu/papi/ https://icl.utk.edu/papi/ . It's a generic library which abstract the details of specific cpu arch and aims to provide a single unify view of performance counters. I think somewhere in there you can see how perf translate counters to intel (or AMD) specific one.
