backends: Introduce chr-testdev
From: Paolo Bonzini <pbonzini@redhat.com>
chr-testdev enables a virtio serial channel to be used for guest
initiated qemu exits. hw/misc/debugexit already enables guest
initiated qemu exits, but only for PC targets. chr-testdev supports
any virtio-capable target. kvm-unit-tests/arm is already making use
of this backend.
Currently there is a single command implemented, "q". It takes a
(prefix) argument for the exit code, thus an exit is implemented by
writing, e.g. "1q", to the virtio-serial port.
It can be used as:
$QEMU ... \
-device virtio-serial-device \
-device virtserialport,chardev=ctd -chardev testdev,id=ctd
or, use:
$QEMU ... \
-device virtio-serial-device \
-device virtconsole,chardev=ctd -chardev testdev,id=ctd
to bind it to virtio-serial port0.
