Hi,

I am trying to use 'perf stat -e uprobes:xyz' on a tracepoint that I ha=
ve
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=3D1001,gid=3D1001)
$ 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 =B4sudo setcap cap_sys_admin+eip $(which perf)=B4,=
 also
without success.

Any ideas?
Thanks,
  Benjamin King
