Hm, this is unexpected I think:
hubble:~> perf top --stdio -u mingo
Error:
You may not have permission to collect stats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid:
-1 - Not paranoid at all
0 - Disallow raw tracepoint access for unpriv
1 - Disallow cpu events for unpriv
2 - Disallow kernel profiling for unpriv
hubble:~> cat /proc/sys/kernel/perf_event_paranoid
-1
hubble:~> perf top --stdio -u
Error: switch `u' requires a value
usage: perf top [<options>]
-u, --uid <user> user to profile
(perf is the latest version from tip:perf/core)
Thanks,
Ingo
