Dear PAPI team,
we would like to access HWCs related to L1/L2 caches but also uncore
events on AMD Zen2 (EPYC 7742) processors. However, no presets seem to
be available. See output of papi_avail below.
Is there any plans to support more AMD Zen2/3 counters through PAPI?
Can we assist with testing, etc?
Cheers,
Jose Gracia

Is there going to be further support for AMD zen2/3 architechtures within PAPI?

Hello,
Are you using a recent enough version of PAPI? Can you try pulling
from the git repo (git clone g...@bitbucket.org:icl/papi.git)
Do you link against an external libpfm4?
On a local machine that is also Zen2 (Family/Model/Stepping 23/49/0)
we get the following cache preset events:
PAPI_L1_ICM 0x80000001 Yes No Level 1 instruction cache misses
PAPI_L2_DCM 0x80000002 Yes No Level 2 data cache misses
PAPI_L2_ICM 0x80000003 Yes No Level 2 instruction cache misses
PAPI_L2_DCH 0x8000003f Yes No Level 2 data cache hits
PAPI_L1_DCA 0x80000040 Yes No Level 1 data cache accesses
PAPI_L2_DCR 0x80000044 Yes No Level 2 data cache reads
PAPI_L2_ICH 0x8000004a Yes No Level 2 instruction cache hits
PAPI_L2_ICR 0x80000050 Yes No Level 2 instruction cache reads
However, on our machine papi_component_avail lists the following PMUs

Did you download PAPI as a tarball, or did you clone from the repo? If
the former, can you please try the latest version from the repo?
thanks,
Anthony

I used the the latest source from https://bitbucket.org/icl/papi/downloads/ (icl-papi-8cdd7e90b398)
The results are mostly the same as above. It looks like the core architecture (AMD Zen2) is supportde,
but what about the EPYC Uncore architecture (see below: Disabled: No uncore PMUs or events found)?
Can it depend on the kernel version?
Thank you

Hello Radim,
Are you using the latest PAPI from the repo?
The other user reporting issues on the Zen2 had problems with the
un-core events, but was able to see 17 presets under the core
(perf_event) component.
thanks,
Anthony

Dear Anthony,
I have been following the conversation here. The value of /proc/sys/kernel/perf_event_paranoid is 2.
I can discuss with our system admins about changing the settings. CAP_SYS_ADMIN is the only change that is required? Also if PAPI is already installed in the current state, then do I need to re-install it with the above change?
Also, any other settings that are required?
With best regards,
Satish Kamath
