[maemo-developers] oprofile for n810

[From: Tuomas Kulve]

Please, keep the list as CC.

So, your kernel does have the oprofile support but you are lacking the
user space tools for it.

I think you need to add this to your sources.list:
deb     http://repository.maemo.org/ chinook free non-free

Be careful to install only the oprofile stuff from there as there are
packages not meant to be installed on the device.


Once you get that working you might want to check this out:
