Hi,
I was trying to use kernprof to see how expensive is each function on
tcp/ip stack.I could run the kernprof and watch the output file using
gprof.I did some file transfer using ftp while running kernprof .Kernprof
gives information about whole lot of functions,but does not give
information about some functions , I am interested like,tcp_sendmsg and
tcp_transmit_skb etc.As far as I know these are not working with interrupt
disabled.What can be the reason.Any help is appreciated.
Also how can I increase the frequency of sampling.Default frequency is
100Hz, but when I add the option "-f 100" or any other frequncy,it gives an
error "frequency out of range."
I couldn't find a manpage on kernprof,it will be great if somebody can send
me a link.
Thanks in advance,
RJ

Subject: Arm support?
Hi,
has anyone profiled linux kernel running on Arm or StrongArm using
kernelprof? If not, how difficult it would be to add the profiling
support for new CPU? Is this question appropriate at all in this list
since Arm is used in embedded world?
