There was also a profiling module from Compaq > WRL in the latest -np kernels that used OSMR2. Never tried it, though. There is no ARM port of oprofile, however I did find this recently : http://www.handhelds.org/pipermail/linux/2000-December/000705.html which talks about a strongARM profiler that looks pretty similar. Hopefully the hints there will let you get your hands on the code. regards john -- "I went to set up a Yahoo ID for my dog.
