perf events available but not supported

[sergipalomas]

Pwrloc displays perf events as available, although they are not supported on my machine (Levante)

$ ./pwrloc.sh -l
========== SLURM ==========
slurm_avail: TRUE
slurm_ptype: (null)
slurm_pfreq: 25 sec

========== PERF ===========
perf_avail: TRUE
perf_events:
        power/energy-cores/
        power/energy-gpu/
        power/energy-pkg/
        power/energy-psys/
        power/energy-ram/

========== PAPI ===========
papi_avail: FALSE

========== NVML ===========
nvml_avail: FALSE

========== ROCM ===========
rocm_avail: FALSE

If I try:
$ perf stat -e "instructions,cycles,energy-cores,energy-pkg,energy-psys,energy-ram" sleep 4
I get this:

 Performance counter stats for 'sleep 4':
