Hi all,
Other than /dev/profile, is there any mechanism available for profiling the kernel? For example, has anyone implemented a __mcount() function to handle a kernel compiled with -pg, or is this even possible?
We're currently profiling the kernel NFS daemon (the entire path from network to disk) using SPECsfs and other benchmarking mechanisms, and before I start working on a home-grown profiling mechanism I'd like to make sure I'm not reinventing the wheel.
BTW: /proc/profile hasn't got enough granularity for our purposes and doesn't provide info such as call-graph statistics.
Regards, Robert.
