If you think it fits reasonably into the virtio spec (ie doesn't implement things at the wrong level of the transport/backend abstraction) then we can implement it in QEMU, and I think it makes more sense to do this than to throw in a random extra serial port. To be actually useful we need to also specify something in the device tree to say "here is where you will find your emergency output and what it is". thanks -- PMM -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
