/*D:010
* Drivers
*
* The Guest needs devices to do anything useful. Since we don't let it touch
* real devices (think of the damage it could do!) we provide virtual devices.
* We could emulate a PCI bus with various devices on it, but that is a fairly
* complex burden for the Host and suboptimal for the Guest, so we have our own
* simple lguest bus and we use "virtio" drivers. These drivers need a set of
* routines from us which will actually do the virtual I/O, but they handle all
* the net/block/console stuff themselves. This means that if we want to add
* a new device, we simply need to write a new virtio driver and create support
* for it in the Launcher: this code won't need to change.
*
* Virtio devices are also used by kvm, so we can simply reuse their optimized
* device drivers. And one day when everyone uses virtio, my plan will be
* complete. Bwahahahah!
*
* Devices are described by a simplified ID, a status byte, and some "config"
* bytes which describe this device's configuration. This is placed by the
* Launcher just above the top of physical memory:
