Agreed, I'd be happy to use the generic driver if MSI is there. What
would MSI support for UIO look like? An array of "struct uio_irq" for
the different vectors?
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.
That would be very useful for device assignment: we can pick up a uio
device, map its vectors, and give them to a guest.
