* Virtio console driverRusty Russell2007-10-23
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>
