I have compiled Oprofile 0.9.3 for PXA320 based platform. And, I am using
Linux kernel version 2.6.21.
The Linux Kernel is compiled with following options enabled.
The compilation of OProfile goes well. But when I run oprofile, it runs in
timer interrupt mode.
I want Oprofile to use Hardware counters. I have cross checked the user
manual of PXA320, it supports hardware performance counters.
I have following question.
1. Is there any other linux kernel config option to enabled for Oprofile?
2. Is there any thing that I have missed?
Please note I am trying the run Oprofile on a target with file system
mounted through NFS. Can this be limitation?
Your help is highly appreciated.
