AMD EPYC 75F3 32-Core Processor is not supported, when I'm trying to launch likwid-perfctr, this error occurs : ERROR - [./src/perfmon.c:perfmon_init_maps:1282] Unsupported Processor. ERROR - [./src/perfmon.c:perfmon_check_counter_map:720] Counter and event maps not initialized.

Why do you need support for this specific architecture?
Please write a short note why you need this specific architecture support.

**Which architecture model, family and further information? CPU or accelerator? **

Is the documentation of the hardware counters publicly available?

Are there already any usable tools (commercial or open-source)?

Please answer the questions in the issue? Especially the architecture model and family is required to add it.

Why do you need support for this specific architecture?
I'm trying to derive the arithmetic intensity of an MRI motion-compensated reconstruction C++ program, and for this purpose I need to work with Likwid to compute the data traffic.
Is the documentation of the hardware counters publicly available? I'm not sure.
with the grep -E "model|family|stepping" /proc/cpuinfo | sort -u command, I get the following output :
cpu family : 25
model : 1
model name : AMD EPYC 75F3 32-Core Processor
stepping : 1
