Hi, I am fairly newbie to this. I am trying to profile kernel modules for optimization.
 
I am currently running on this system.
uname -a
Linux svbu-vm-host-1 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux
My version of oprofile is 0.9.2
When trying to: opcontrol --callgraph=1
I get this error message: Call-graph profiling unsupported on this kernel/hardware
 
Everywhere I looked seems to indicate that I should be getting callgraph support. Is there something missing that I need to do in order to get callgraphs
 
Thank you for your help and time in advance.
