Whats the difference between the RotateRight kernel modules and the oprofile kernel module?
The rrprofile kernel module is based on oprofile, but adds support for time stamps, disables nap during sampling and supports both PMC and timer interrupt based sampling without reloading the kernel module. In addition, rrnotify reduces the overhead of profiling by deferring the gathering of process memory maps until after profiling is finished (when possible).
