Subject: perf tracepoints for regular user?
Date: Fri, 15 Jan 2016 22:05:16 +0100	[thread overview]
Message-ID: <20160115210516.GA6329@localhost> (raw)

Hi,

I am trying to use 'perf stat -e uprobes:xyz' on a tracepoint that I have
previously set, but with no success.
I thought that I should be able to do that when allowing my user access to
debugfs, but this is what I get:

$ id -u;id -g
1001
1001
$ mount|grep debug
none on /sys/kernel/debug type debugfs (rw,uid=1001,gid=1001)
$ ls /sys/kernel/debug
acpi  bluetooth  cleancache  dell_laptop  dri extfrag ...
$ ls /sys/kernel/debug/tracing/
ls: cannot open directory /sys/kernel/debug/tracing/: Permission denied

So, my user can't look in the tracing subdirectory and perf list doesn't show
the uprobes either.

I have also tried to ´sudo setcap cap_sys_admin+eip $(which perf)´, also
without success.

Any ideas?
Thanks,
  Benjamin King
