Hi,

can anybody give me a hint how I can compile oprofile for Kamikaze - 2.6.x kernel?
I've found some oprofile files in the kernel directory, however I do not have a clue how to build the corresponding oprofile tools?

Any hints? Thanks,

Ingo

This is as of r22630, which I have tested. Probably works way before that also:

# make menuconfig

Then from the menu, "Global build settings" => under -- Kernel Build Options => "Compile the kernel with profiling enabled"

Back at the main menu, "Development" => "oprofile". Choose whether you want it as a module or part of the image. You will also need some extra packages:

libpopt: packages/libs/popt
libstdcpp, part of base-files
objdump: packages/devel/binutils
libbfd: packages/devel/binutils

If you already have them in the build tree they will automatically be selected when you select oprofile.

When you do the build, it will build a new kernel, create a profiling module call oprofile.ko which is in a kmod-oprofile_[kernel]_[version]_[arch].ipk package. You ned to make sure that gets installed along with the oprofile package plus all the dependencies.
