[okl4-developer] An IPC driver for Wombat

[Geoff White]

Greetz,

I'd like to write an IPC driver for Wombat, what I mean by that is a way to
send L4 IPC messages from the *NIX domain.
I'm doing this mostly to learn about writing device drivers in general and
to provide a base to write tools that will help in debugging native mode L4
process communication (when the time comes).

The question that I have is what do you think the best abstraction to use
is?
Should I create a char driver, a block device or a network driver?
Obviously char drivers are the easiest, but I would think a network driver
would be the more natural and logical expression.
Has anyone at OKLabs done this? How did you go about it?


I'm really looking for ideas and challenge, not necessarily working code.


Geoff
