Hi, folks I don't know what "perf_event_paranoid" is for. Sometimes `perf` told me tweaking perf_event_paranoid. For example,
$ perf stat -e branches:pp ls No permission to collect stats. Consider tweaking /proc/sys/kernel/perf_event_paranoid. I cannot find any document talks about what perf_event_paranoid is and what we can do on it. Any suggestion appreciated.
