Its extremely hard as you've probably noticed by now.

The kernel IRQ handling is pretty flexible. A concious decision was made many years ago not to try and limit it to do a pageable kernel as RAM was far cheaper than the pain, and getting cheaper by the day.

Realistically - the one case it is done right now is by the mainframe people, simply because the underlying hypervisor does it. You probably have much more chance that way using a microkernel (real one not MACH) underneath. Still a huge task. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
