Re: keyboard access with oskit-mach

The keyboard and video questions are really quite separate,
so I am answering them in two separate threads.

Anything using the oskit-mach "console" driver at all should be considered
a temporary hack.  For one thing, if you boot with the serial console then
there isn't any device that gives you access to the PC keyboard.  Moreover,
the "direct_cons" driver is very simplistic, not all that efficient or
robust or featureful (probably doesn't work with all the oddball hardware
flavors a real driver would).  That driver (and the serial driver used by
the serial console) are really intended for bootstrapping and kernel
debugging.  (Also note that there is nothing at all in oskit-mach that will
get you the ps2 mouse port.)

The long-term solution is to cleanly incorporate some real keyboard/ps2
drivers into the oskit (encapsulate *BSD and/or Linux drivers), along with
USB and whatever else.  But that is some substantial work and not a task I
would recommend for anyone who isn't intimately familiar with the oskit and
its style of driver-stealing.

All that said, yes I think turning on DC_RAW would make it more or less
work.  There is no interface for diddling the keyboard LEDs, which you
would like to be able to do for real usability.
