I am having trouble getting OProfile to run on a arm linux system. I can
compile OProfile without any trouble, but when I try to start it I get some
error messages telling me that my kernel does not have the OProfile module.
I have tried recompiling my kernel, but since I am quite new to Linux, and
extremely new when it comes to recompiling the kernel, this is giving me
some trouble. I followed
http://www.falkotimme.com/howtos/debian_kernel2.6_compile/ and successfully
compiled both a kernel with the OProfile option set to included and one with
it set as module. I can't seem to get mkinitrd to work though (or rather,
can't find it) but after searching around a bit, I found that mkinitramfs is
probably what I want to use. I successfully created a ramdisk and
successfully started the system from the new kernel and ramdisk, but I still
get the same error complaining about no kernel support. Have I missed
something? When I do modprobe -l oprofile in my desktop computer, i find the
oprofile module, but when I do the same on the arm system, it finds nothing.
Since I have never recompiled the kernel, and don't really know how modules
work, I am more or less at a loss about what to do next.
Grateful for any suggestions
