Iglesias" We've been creating the virtio-mmio devices in forwards order but since the qbus lists prepend (rather than append) entries, the virtio busses end up with decreasing base address order. Xen enables virtio-mmio nodes in forwards order so there's been a missmatch. So far, we've been working around this with an out-of-tree patch to Xen. This reverses the order making sure the virtio busses end up ordered with increasing base addresses avoiding the need to patch Xen. Signed-off-by: Edgar E.
