Yep. I already have an issue about virtio filed at <https://gitlab.com/sortix/sortix/issues/473>. Not too high priority to implement but something I'd love to get to. Feel free to post additional hints there if you have additional tips for when I get around to doing it.

I started a note on your gitlab issue, but saw you already had an mmio reference linked. i did the pci version and it looks about the same complexity.

aside from a reference, being able to instrument the device side on qemu makes debugging drivers a total cakewalk. so do that. best of luck with your project. i wish more people went through the exercise. even though a mature OS after decades of maintenance might exceed 1M lines, you really dont need anywhere close to that to get what you need done. you learn alot, and can make your own model
