Hi Michael,

In commit 1a937693993f ("virtio: new feature to detect IOMMU device quirk"),
you added a new feature bit (VIRTIO_F_IOMMU_PLATFORM) to describe whether
or not a given virtio device requires physical address or bus addresses.

Is there a plan to get this incorporated into the virtio spec [1]? At the
moment, I can't see a working draft that includes the new bit. Having it
in the spec would help convince implementors that it's not just a Linux
thing.

Thanks,

Will
