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 here.
Mdev drivers outside Dom0
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 XenProject Wiki.
NVMM
This section will cover NetBSD's NVMM.
Missing Functionality
VFIO.
Additional Documentation
For additional documentation read From Zero to NVMM.
