Are perf memory events supported on AMD EPYC 7501?

Hi,

I want to get the distribution of memory accesses on different memory hierarchy levels of an application, on Linux.

Thus, I opted for using perf mem record on my AMD EPYC 7501 with Linux v6.2.

However, perf immediately terminates with the failure message

failed: memory events not supported

Are memory events supported on such CPUS? If yes, then how can I sample my application?

Cheers
