I'm not familiar with the uio internals, but for the interface, an ioctl() on the fd to assign an eventfd to an MSI vector. Similar to ioeventfd, but instead of mapping a doorbell to an eventfd, it maps a real MSI to an eventfd.uio will never support ioctls.

What's irqcontrol? -- Do not meddle in the internals of kernels, for they are subtle and quick to panic.
