Would it not have been better to build on the previously discussed (and mostly agreed) PV IOMMU interface? (See https://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01428.html). An RFC implementation series was also posted (https://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01441.html).
