perf-stat: count events for BPF programs

perf-stat: count events for BPF programs

[Sebastiano Miano]

Dear all,
I have a question regarding the use of the new 'perf stat -b' feature
to collect various events for a specific eBPF program.

I am running the following command on kernel 6.0.9-060009-generic:
sudo ./perf stat -e cycles --bpf-prog 96 --interval-print 1000

but I am unable to get any metric. The output is the following:
#   time                   counts unit              events
     1.001015662    <not supported>      cycles
     2.002171264    <not supported>      cycles
     3.003229801    <not supported>      cycles

any idea/suggestion of which could be the problem?

Thanks,
Sebastiano
