I’m working towards getting OProfile running on at least one of my desktop-type machines; hopefully it’ll work sufficiently well on the Pentium-MMX, since that’s the easiest one to drive into saturation.

Perf is included in every kernel these days, it is way better than
oprofile, and easy to build if you are running natively.
in your linux build dir:

cd tools
make # to get more info

I think for benefit of the audience a fresh patch would be better. I
will see if this applies on top of my old patches.
