I mean it is the registration function provided by the subsystem that owns the class, for instance tpm_chip_register(), ib_register_device(), register_netdev(), rtc_register_device() etc So if you have some vhost (vhost net?) class then you'd have some vhost_vdpa_init/alloc(); vhost_vdpa_register(), sequence presumably. (vs trying to do it with a bus matcher) I recommend to look at rtc and tpm for fairly simple easy to follow pa...

Data center backends use more and more RDMA or RoCE devices and more and more software runs in virtualized environment. There is a need for a standard to enable RDMA/RoCE on Virtual Machines. Virtio is the optimal solution since is the de-facto para-virtualizaton technology and also because the Virtio specification allows Hardware Vendors to support Virtio protocol natively in order to achieve
