Hi, All,
I have gotten some problems to run oprofile. Could anybody help me out? thanks
in advance.
My system is Intel DuoCore (64bit). CPU family: 6, Model 15, Model name: Xeon
(5150 @2.66 GHz). System is running SL5.0.
Just because your hardware is capable of doing 64 bit does not mean you
installed a 64 bit kernel.
What is the output of
uname -a
-Connie Sieh
When I check the Profile's CPU type, "cat /dev/oprofile/cput_type" shows
"i386/core_2". Is this correct? But my system is 64bit.
Also, I set Oprofile to profile different events such as L1I_MISSES" , but "Opreport"
keeps on giving me the result of the event "CPU_CLK_UNHALTED". Anything wrong?
Some results are as follows:
[EMAIL PROTECTED] oprofile]# opcontrol --reset
[EMAIL PROTECTED] oprofile]# opcontrol --start
....runing my application......
[EMAIL PROTECTED] oprofile]# opcontrol --dump
[EMAIL PROTECTED] oprofile]# opcontrol --status
