Hi,
All the other perf tooling can be used as a normal user. At one point,
I had to touch /proc/sys/kernel/perf_event_paranoid to get me numbers
on a PMU event without a symbolic name, but that's about it.
perf-trace seems to be the exception though:
artagnon|perf-core=:~/src/linux/tools/perf$ perf trace -a -e open
Couldn't read the raw_syscalls tracepoints information!
The responsible codepath is:
if (perf_evlist__add_newtp(evlist, "raw_syscalls", "sys_enter",
trace__sys_enter) ||
perf_evlist__add_newtp(evlist, "raw_syscalls", "sys_exit",
trace__sys_exit)) {
I don't understand much of what's going on, but what can be done to
improve the situation for users?
Thanks.
