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.
