Out-of-process devices is not really something QEMU's design
tries to support. The assumption is that you should be writing
the device as a QEMU device model that is compiled into the
QEMU process along with everything else. This is doubly true
for IOMMUs, which by their nature need to sit between the CPU
and other devices, and have a fairly complicated interface that's
closely tied to the details of QEMU's memory subsystem in
order to be efficient.
