an user has this question:

Does anyone try the tool "oprofile" in the source code folder
"external".
When I use command "oprofile -r start", it will show "Unable to open
cpu_type file for reading Make sure you have done opcontrol --init"
After I finish opcontrol --init, it show the same.
Does I need to set up something first, there is no guide to tell how
to use it.

Does anyone has the answer?
