    Profiling L3 counters on AMD EPYC

    mrmeswani

      I have a system with AMD EPYC 7551 32-Core Processor running Ubuntu and with AMDuProf installed

       

      I have been trying to collect L3 counters but i get the following message

       

      Running the example cmd in uProf User guide

       

      AMDuProfCLI collect -e event=timer,interval=1 -e event=0xb001,umask=0x80,slicemask=0xF,threadmask=0xFF -a -d 10

      There was a problem configuring the L3 profile event(0xb001).

       

      Also tried the command posted in another discussion thread

       

      ./AMDuProfCLI collect -e event=timer,interval=1 -e event=0xb006,umask=0x01,slicemask=0xF,threadmask=0xFF -a -d 10 -o /tmp/out

      There was a problem configuring the L3 profile event(0xb006).

       

      Why is this counter not working ? I am running as root.
