[PATCH 0/2] tools/virtio: virtio_ring testing tool
This implements a virtio simulator:
- adds stubs for enough support functions to compile
virtio ring in userspace.
- Adds a stub vhost based module this can talk to.
This should help us decide things like which ring layout
works best.
Communication is currently done using an eventfd descriptor.
This means there's a shared spinlock there: what I would like to do
in the future, is run
