Feedback form is now closed.
The final design for PV-IOMMU was posted to xen-devel more than a year ago (see https://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01428.html) and RFC code was posted at around the same time (see https://lists.xenproject.org/archives/html/xen-devel/2016-02/threads.html#01441). Unfortunately no further progress has been made on it since then, despite Citrix XenServer carrying a version of the code. The interface is important for several reasons, one of them being that it is a key enabler for virtual graphics implementations (where device drivers running a service domain need to DMA map memory belonging to a guest domain).
