OK well, assuming Christoph can solve the direct case in a way that
also work for the virtio !iommu case, we still want some bit of logic
somewhere that will "switch" to swiotlb based ops if the DMA mask is
limited.

You mentioned an RFC for that ? Do you happen to have a link ?

No but Christoph did I think.

Ok I missed that, sorry, I'll dig it out. Thanks.

Cheers,
