This is a draft patchset for a new vendor specific VFIO driver

(DSC). This driver is device type agnostic and live migration is
supported as long as the underlying SR-IOV VF supports live migration
on the DSC. This driver is a client of the newly introduced pds_core
driver, which the latest version can be referenced at:
Just as a broken clock: non-standard nvme live migration is not
acceptable. Please work with the NVMe technical workning group to
get this feature standardized. Note that despite various interested
parties on linux lists I've seen exactly zero activity from the
(not so) smart nic vendors active there.
You're right, we intend to work with the respective groups, and we
removed any mention of NVMe from the series. However, this solution
applies to our other PCI devices.
