I'm having a bit of difficulty getting oprofile to correctly profile my custom kernel module (or even profile the current kernel in general). I'm running CentOS 6.3 with a custom 3.2 kernel. Here's the process i used to install oprofile-0.9.8:

./configure --with-kernel=/home/username/linux-3.2.32
sudo make install

Then i run operf to profile the entire system:

sudo /usr/local/bin/operf -s

However, when i check the oprofile_data/current folder, it's empty and the "opreport" command throws a "no samples found" error

Any suggestions? I'm sure its just something small..
