Your first step still remains the fairly independent port of Adeos/Ipipe
over MIPS. Philippe already pointed out the available resources. Start
over a recent vanilla kernel (or do you need special patches for your
targets?), make Linux boot with Ipipe enabled, then stress the event
pipeline with a simple Ipipe test module.

Once this works you can proceed to Xenomai, porting over what's under
ksrc/arch/<arch> and include/asm-<arch>. Not all internal functions may
be documented. Try to grab their meaning from other archs and/or their
usage - or ask on this list.

Another hint: post your patches early even if they do not work yet. We
may have a look and comment on style and functionality. This will make
it easier to finally merge them (which should be your goal to ease
long-term maintenance). And it may attract early adopters that can
provide further feedback and test results.
