V) Enabling the PMC on Linux
I don't know how to do it, sorry :-) Any idea very much welcome.
On linux you may use oprofile from http://oprofile.sf.net, depending on the
version and the cpu you may need to apply a patch[1] to access a set of the
possibile counters from the userspace application. You can always define them
using the kernel interface /dev/oprofile/* .
