[PATCH RFC 0/5] virtio_pci: modern driver
Based on Rusty's patches. Coding style and funny jokes are his. Bugs and a star wars reference (should be easy to spot) are mine. Untested, but useful as basis for beginning the qemu work. TODO: = simplify probing: use a common probe function, probe with modern driver first, if that fails - probe with legacy driver. BUGS: ATM legacy driver can win and drive a transitional device
