This is a way to create virtio based devices from user space. This is the background for this patch: We have some images works fine under qemu, we'd like to also run the same image on Google Cloud. Currently Google Cloud doesn't support virtio-vga. I had a patch to create a virtio-vga from kernel directly: https://www.spinics.net/lists/dri-devel/msg248573.html Then I got feedback from Gerd that maybe it's better to change that to something like uvirtio. Since I really don't have other use cases for now, I just implemented the minimal stuff which work for my use case.
