It's just like LKML people already told you: there is no generic way to do cross-domain sharing (with PREEMPT_RT, it's sharing between RT-capable and non-capable drivers). What you can always do is writing such an (RTDM-)stub for the non-RT device to shut up the IRQ source in hardware ASAP. RTDM already supports sharing between RT devices. Jan
