There is a documentation bug which caused a pfmon bug. With this option, pfmon does not set PMC12 correctly. As a workaround, you can use: pfmon –btb-ptm-incorrect –btb-ppm-incorrect… This bug is not present in pfmon-3.0. • Pfmon-3.0 does not work with RHEL-3.0, Suse SLES8 or any 2.4-based kernel? This version of pfmon is meant to be used ONLY with a perfmon-2.x kernel interface which is available only in the 2.6 kernel series. • Pfmon-2.0 does not work with my 2.6.x kernel? This version of pfmon is meant to be used with the perfmon-1.x kernel interface ONLY. The 2.6.x kernels all have the next generation perfmon-2.x interface which is not backward compatible with perfmon-1.x. You need to use pfmon-3.0 with 2.6.x kernels. • Pfmon-2.0 does not work with RHEL-3.0? The official RHEL-3.0 includes a bogus kernel perfmon-1.x subsystem. It is strongly recommended NOT to use it until a patch is provided in the subsequent updates to RHEL. • Linux kernel perfmon-1.3 or higher can exclude idl
