Hi all

 

I'm trying to use oprofile with i.MX6.

When I try to use oprofile, it doesn't work properly.

Also I tried following command and got following message.

 

# operf openssl speed -evp aes-256 cbc
Your kernel's Performance Events Subsystem does not support your processor type.


As a above result, I think that i.MX6 doesn't support a oprofile.

According to the http://oprofile.sourceforge.net/doc/perf_events.html, when user get the message, user need to install OProfile 0.9.9.

 

Do I need to install OProfile 0.9.9 when I use oprofile with i.MX6 ?
