Subject: perf-stat: count events for BPF programs
Date: Mon, 5 Dec 2022 13:52:15 +0100 [thread overview]
Message-ID: <CAMENy5rSv0G45yZ-5Wmj9oZCb8XDVCX-oO8RsQ942q-zSF8yCA@mail.gmail.com> (raw)
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
