What should I do to resolve this issue?

I noticed that pcm-memory command returns the following error message.

Detected Intel(R) Celeron(R) J4005 CPU @ 2.00GHz "Intel(r) microarchitecture codename unknown" stepping 1
Unsupported processor model (122).

According to the source file on github, pcm-memory checks existence of PCICFG uncore PMON.

 pcm/pcm-memory.cpp at master · opcm/pcm (github.com)

It looks like that PCICFG uncore PMON are supported by Xeon processors.

I suspect that some features of VTune Profiler(System Overview, Memory Access, Input and Output etc..) is working on Xeon processors only, is it correct?

Hi,

Thanks for posting in Intel forums.

We are checking on this. We will get back to you soon.

Hi zyake,

Yes, you are correct hardware event based sampling analysis is supported on Intel Xeon Processors v3 (or later) family and 4th generation (or later) Intel Core processors. Also we tried the system overview in our xeon processor machine with vtune 2022.0 and it is working fine. Support for older processors is deprecated effective Intel® VTune Profiler 2022.0 release and will be removed in future.

I understand that older processor is not supported by vtune profiler.

I'll try this feature on a supported processor.
