We initially changes IRQ_CREATE_IRQCHIP to take an argument but that was causing an x86 ABI breakage (ioctl number changing). So we'll probably be creating a new one. >From there, nothing fancy really, just an ioctl with an IRQ chip type at the beginning followed by a union of type-specific parameters. The main problem we haven't sorted out yet is how to replace some of the horrors related to mapping interrupts that have tendrils all the way into virtio-pci etc... in kemu that don't apply to use (well mostly) and the interaction with in-kernel generated interrupts to avoid going through qemu for vhost ec...
