This special driver makes it possible to temporary use NMI debugger port as a normal console by issuing 'nmi_console' command (assuming that the port is attached to KGDB).
No ref counting, no tty port, no compliance with the tty behaviour. Concept looks fine but it needs porting to reflect a kernel newer than about 2.6.18 8)
I would take a quick look at the tty_port helpers and also check v -next which makes the tty_port mandatory. That'll pretty much cover your needs for locking, semantics and the like.
