No, because Fedora 13 is based upon the 2.6.33 kernel. The perfmon2 patch set only works on 2.6.30 kernels and earlier. You're better off using the newer kernel API called perf_events. There's a user space tool that's available with Fedora 13 and later, called "perf" (do a "yum install perf" and you should get it). If you want to do exactly what you are talking about instead of using either "perf record" (for profiling) or "perf stat" (for counting events), you will need to write the code yourself. To write the code yourself, you could use either the raw kernel API, or use PAPI which should make your job a little easier. PAPI should also be available via yum in Fedora 13, I think (try "yum install papi"). You can find the programming details of PAPI here: http://icl.cs.utk.edu/projects/papi/wiki/PAPIC:PAPI.3 If you have specific questions about how to use PAPI, PAPI has its own mailing list. - Corey ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
