B.1 Fedora Core 2 (FC2)

For FC2, Red Hat provides packages for oprofile that should be used rather than those downloaded from the oprofile Web site. The uniprocessor kernel does not provide the necessary oprofile drivers. Red Hat packages the necessary oprofile kernel modules with the smp version of the kernel. If you want to run oprofile, you must use the smp kernel, even if you are running it on a single-processor machine.
