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.
