Howto add TIPC-support into kernel?

Howto add TIPC-support into kernel?

Hi!

I'm writing a recipe for a piece of software that requires TIPC support in the kernel.  I've tried to figure out a way to accomplish this within my bb-file, but with no success.  Is there a way to do such thing with Yocto, currently I run 'bitbake -c menuconfig linux-yocto' (or is it yocto-linux, can't recall) and then I add 'kernel-modules' to IMAGE_INSTALL_append in my 'local.conf'-file?  I would like to have this dependency some-how contained within my recipe.

Thanks!

Best regards,
Jonas Jonsson

Are you primarily concerned with getting the kernel options enabled and
then the built modules installed onto your target ? (I ask because
TIPC userspace can come into play .. depending on your usecase).

If so, you'd want to add a linux-yocto_3.4.bbappend (assuming you are
using the 3.4 kernel) to your layer, and put your options into a .cfg
fragment that you append to the SRC_URI (just like any patch or other
file). Those options will be added to the config on your next build and
installed.

In that same layer, you can add kernel-modules to IMAGE_INSTALL and
you'll get the build and install whenever the layer is active.

There are other ways to do this as well, but what I have above is
what I typically do in a distro or BSP layer.

Cheers,

Bruce
