== KVM ==
This section will cover existing support in KVM for VFIO-Mdev and ongoing issues with it's existing implementation.
=== Missing Functionality ===
Nested SR-IOV.
== Xen ==
This section will cover efforts to support the Xen hypervisor with open device mediation software.
XAPI docs for virtual GPUs can be read [https://xapi-project.github.io/xen-api/classes/vgpu_type.html here].
=== Mdev drivers outside Dom0 ===
[https://xenbits.xen.org/docs/unstable/designs/launch/hyperlaunch.html Xen Hyperlaunch] aims to disaggregate Dom0's monolithic functions. This includes a discrete domain for device drivers.
=== Missing Functionality ===
IOMMU Groups (discussions around extending or reworking Xen's IOMMU to include IOMMU Groups is ongoing).
=== Additional Documentation ===
For additional documentation check the [https://wiki.xenproject.org/wiki/Main_Page XenProject Wiki].
== NVMM ==
This section will cover NetBSD's NVMM.
=== Missing Functionality ===
VFIO.
=== Additional Documentation ===
For additional documentation read [https://blog.netbsd.org/tnf/entry/from_zero_to_nvmm From Zero to NVMM].
