It's similar to other similar vhost-user VIRTIO devices. I'm aware of the work in progress by Alex Bennée to simplify similar devices and avoid excessive code duplication. I think the SCMI device support doesn't bring anything special and it can be rebased on the given work if/once it is merged. The device has been tested with a prototype rust-vmm based vhost-user-scmi daemon emulating a sensor device and a Linux guest OS (the production version of the vhost-user daemon is developed at https://github.com/mz-pdm/vhost-device/tree/scmi). v3: - Rebased on master after one of the patches had been merged. v2: - A missing trailing space additionally added in the comment typo fix. - A note about testing added above.
