680x0 Linux FAQ (TM)

ABOUT THIS FAQ
This FAQ is intended to provide general information on the 680x0 Linux
port project which is currently underway. Mainly, it's an attempt to
cut down on the flow of email that inevitably comes in every time I
post something about the project. ;)
WHEN WILL 680x0 LINUX BE AVAILABLE TO THE PUBLIC?
I don't know. A couple months, maybe. We're working hard on it at
this point, and advancing leaps and bounds (and a few stumbles).
There's really no point to releasing the current system to the public.
It's not useful, and only occasionally even mildly entertaining. ;)
WHAT IS THE CURRENT STATUS OF THE PORT?
We're still working on the basic kernel at this point. The scheduler,
memory management code, interrupt code, filesystem code, and handful
of drivers have been implemented. There's not much to see right now.
The system comes up and goes through some of the startup process, then
sits there and idles at you. ;)
WHAT PLATFORMS WILL IT RUN ON?
The Amiga port project is the only effort to port Linux to a 680x0
platform that I'm aware of. However, we are paying attention to
portability where possible. It is our intention to cooperate with
other groups willing to work with us.
I expect that once we make our first public release of the system,
several groups will begin porting our sources to various platforms.
Interest has been shown by Atari programmers, mostly. There are also
a few people hoping to bring Linux up on Sun 3's. I haven't heard
from many Macintosh folks. In all probability only the startup code,
interrupt code, and drivers will need re-writing to get the system
running on these systems, or any others with the necessary basic
hardware.
I'm aware that the phrase "necessary basic hardware" begs some
explanation. Simply put, that would be a machine with a 68020+68851,
68030 (non-EC model), or 68040 processor, at least a couple megs of
RAM, a good amount of hard disk space, and obviously some form of text
i/o device (i.e. you technically don't even need a display and
keyboard if you can plug a terminal into it).
There _has_ been talk of a port that could run on non-MMU-equipped
machines as well, though it would lack the obvious features inherent
in a memory-managed operating system (e.g. true virtual memory, memory
protection). There is currently no effort underway to implement such a
system that I'm aware of.
HOW COMPATIBLE WILL IT BE WITH OTHER SYSTEMS?
We, of course, hope that 680x0 Linux will be compatible (at the source
level) with 80x86 Linux, as well as many other Unix or Unix-like
systems. Linux is POSIX.1 compliant, which helps quite a bit with
porting software to it.
Binary compatibility with _any_ OS other than 680x0 Linux ports is
highly unlikely.
WILL X WINDOWS BE AVAILABLE FOR 680x0 LINUX?
I get this question a lot, so I figured it's worth having its own
section. The answer is yes... probably... eventually. ;)
At this point, we have one volunteer to port the mono server to the
Amiga version of Linux once the system is stable.
WILL THE AMIGA PORT RUN UNDER OR EMULATE AMIGADOS?
No. Actually, the latter is a possibility, I guess.
WHAT ABOUT MACH?
There is a separate effort to port CMU's Mach kernel to the Amiga and
other 680x0 platforms. I'm not really familiar with their work.
We've only stolen a little code from them. ;) Anyway, our Linux port
is not intended to run under Mach. It runs "on the metal".
CAN I BE AN ALPHA/BETA TESTER?
We're not currently at a stage where we need any testers. (See above
under the section CURRENT STATUS OF THE PORT.)
IS THERE A MAILING LIST?
We have a channel on the Linux Activists Mailing List called '680x0'
for discussion of the port. Currently, it's rather quiet. However,
it's the "official" source of information on the system. On the
other hand, any important announcements will also be posted to the
newsgroups in which this FAQ appears.
