Add support for named virtio console ports

Authored by jceel on Jul 11 2016, 12:09 PM.



Following change adds support for named ports in the virtio_console(4) driver. It does that by creating tty aliases in format /dev/vtcon/<portname> upon receiving PORT_NAME event (id = 7) over the control queue. The aliases point to already existing /dev/ttyVx.y tty device nodes.

Test Plan

Code can be tested using qemu-kvm in linux:
