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. Jan
