[RFC 00/13] virtio-iommu on non-devicetree platforms
I'm seeking feedback on multi-platform support for virtio-iommu. At the
moment only devicetree (DT) is supported and we don't have a pleasant
solution for other platforms. Once we figure out the topology
description, x86 support is trivial.
Since the IOMMU manages memory accesses from other devices, the guest
kernel needs to initialize the IOMMU before endpoints start issuing DMA.

modeling...
I''ve tried tackling this many ways on my own and can''t find a good solution:
Breaking it down to something simplier...
Venue
has one address
Person
has one address
Address
belongs to state
Assuming I don''t want to do tables for venue_addresses and person_addresses.
What is the best way to model this using rails... big thing here is i
want to be able
to reuse a
