OSDL does one for the development kernel, and Jack Perdue has pre-patched RedHat kernel .rpms. (For Jack's stuff, check out PAPI -> Links -> Related Software.) I'm planning to simplify the kernel <--> user-space interface in perfctr-2.6 (drop /proc/pid/perfctr and go back to /dev/perfctr), and then I _think_ I can do a version that doesn't require patching kernel source. (It will do binary code patching at module load-time instead. Horrible as that sounds, it's easier to deal with for users.) /Mikael
