As for the vhost user daemon part, I wonder whether there is already something publicly available, which could be used or benefit from cooperation. If not then I'll start making my own implementation. At the moment, I don't need anything fancy requiring kernel changes or so, I would probably aim for stuff accessible via /sys/bus/scmi_protocol and possibly stuff exposed via VirtIO SCMI some way. Thanks, Milan
