Thanks Greg. Can you give me some pointers here as to what needs to be
done here. Looking at the code for virtio, it looks like I would need to add stuff
to scripts/mod/file2alias.c as well as to include/linux/mod_devicetable.h. Will

accept patches for these files to support an ID space for Hyper-V vmbus drivers.

Yes, I will take patches for those files to implement this.

Along with those files, you also need a way to tell userspace that new
UIDS are found before the individual drivers are loaded.  Hopefully you
can do that now, but if not, it will need to be implemented.

Could you elaborate on what user level changes I will have to do.

It's all kernel code, but you need to be emiting "device found" messages
to userspace through the hotplug bus event when you find the devices.
Just fill in the correct fields in your hotplug callback and you should
be fine.

Look at the PCI bus hotplug callback as an example of what is needed if
you need an example.

hope this helps,
