Virtio console driver This is an hvc-based virtio console driver. It's suboptimal becuase hvc expects to have raw access to interrupts and virtio doesn't assume that, so it currently polls. There are two solutions: expose hvc's "kick" interface, or wean off hvc. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

virtio: clarify that ABI is usable by any implementations We want others to implement and use virtio, so it makes sense to BSD license the non-__KERNEL__ parts of the headers to make this crystal clear.
