Trouble convincing OProfile to use my "vmlinux"

I am trying to profile the kernel but can't seem to convince OProfile
to use my "vmlinux" image.  I am doing this:

    % uname -a
    Linux schmidt 2.6.15 #1 Wed Jun 7 12:09:02 EDT 2006 i686 GNU/Linux
    % sudo opcontrol --init
    % sudo opcontrol --reset 
    % sudo opcontrol --vmlinux=/boot/vmlinux-`uname -r`
    % sudo opcontrol --status
    Daemon running: pid 10399
    Separate options: none
    vmlinux file: /boot/vmlinux-2.6.15
    Image filter: none
    Call-graph depth: 0
    % ls -l /boot/vmlinux-2.6.15 
    -rw-r--r-- 1 root root 3103965 2006-06-07 13:52 /boot/vmlinux-2.6.15
    % sudo opcontrol --start ; time cat `for (( i=0; $i < 256; i++ )); do echo ../../tmp/XO-TOOLS.tar.gz ; done` >
/dev/null ; sudo opcontrol --stop
    Profiler running.

Exactly. You need to restart the daemon.

Thanks, John.  That worked.

You need to talk to Gentoo. Maybe they don't have oprofile enabled.

Re: install on gentoo

Hi Mark,

You need to make sure oprofile is built into the kernel or loaded as a module 
(called oprofile). this module is included in the linux kernel source.
I have an old gentoo box around (running 2.6.11-gentoo-r...something) and i 
notice it doesnt have oprofile module built (i didnt configure this kernel, 
someone else did, so i dont know if thats the default or not). but if you 
configure your own kernel, when you make menuconfig (or whatever your 
preferred kernel config method is), you want to look under 'Profiling 
support' on the top level menu, and enable Oprofile system profiling (as a 
module is fine). then oprofile should work.

install on gentoo

hi all,

I am not targetting the kernel to debug, but I understand
the kernel is needed to track what my program is doing.

I am installing like this..
su root
./configure --with-kernel-support
make
make install

I don't see any errors in configure/make/make install.
I did need to add /usr/local/bin to my PATH.

When I run with
# opcontrol --no-vmlinux
FATAL: Module oprofile not found.
FATAL: Module oprofile not found.
Kernel doesn't support oprofile

Any ideas?

kernel = 2.6.12-gentoo-r6

Obtained 0.9.1 from
  http://sourceforge.net/projects/oprofile
because the .gz files I grabbed using firefox and wget from
  http://oprofile.sourceforge.net/download/
would not unpack.  (problem?)

Patched 0.9.1 with
  oprofile-0.9.1-anon.patch

thank you!!
cheers,

Mark
