the devices in port/devocns.c are hardcoded to assume that there's a
keyboard, a uart, a vga console in some form or another. There are queues
and pointers in there that get initialized in random places. Random
different devices initialize (or don't) those variables to enable
different kinds of console I/O.
I understand the pragmatism, but it's a jungle in there.
There are machines that don't have keyboard, uarts, or vga coming out now.
port/devcons.c is living on borrowed time and we need to do better.
