Hello,
This is kind of a test message to see if we are (Ralf and I) are on
the SGI Linux mailing list.
Ralf and I have joined the Linux/SGI project (he will mail his very
own presentation later). The idea basically is that we will be
getting a machine each one to finish the Linux on SGI port.
Ralf is the guru behind the original Linux/MIPS, so he will be
handling most of the low-level code in the port. And I was part of
the team that ported Linux to the SPARC.
My experience with MIPS hardware is close to none, so I will be
doing other parts of the port. The very first project I have is to
port the Linux/SPARC SILO boot loader to the SGI.
Later, make the libc reliable on the MIPS machines and work on the
kernel support for your graphics cards.
I also would love to get my hands on writing parts of the IRIX
emulation code (to get all those cute toys you have working on
Linux/SGI without recompiling them), maybe also learn a bit about isdn
and your audio chips while writing the drivers for them.
Once this is done, I would love to write the native/free versions
for some of your libraries that access the cool video hardware on the
SGI machines and make Linux/SGI not just another Linux port, but a
cute port that takes advantage of all of the SGI graphics hardware.
So, well, this was like my presentation to the list. Ahem, now,
I would like to know more about your video hardware for the kernel
support, where can I get information on this?
We don't have the machines just yet, but I have been reading this
huge R4k book I got for free from www.mips.com :-)
Best wishes,
Miguel.

Thanks for the introduction Miguel; I'd like to use the chance to drop
some words about what I'm doing right now on Linux and what the status
of this is.
As you know David left SGI again in the late August. At that time he
had not only completed a good part of the SGI specific stuff but also
made a lot of improofments to the generic MIPS parts of the kernel. At
that time his kernel was based on Linus' 2.0.14.
At the same time I was working mostly independend of him; luckily. My target
machines were at that time the good old Magnum 4000 and it's OEM variant
M700-10 from Olivetti, the Magnum based Acer PICA machine and SNI's RM200.
When Ariel mailed me about working on Linux/SGI my kernel for these
machines was based on Linux 2.1.21.
It's obvious that our kernels have diverged a good bit from each other
and right now I'm working on merging both kernel sources into one single
tree again.
The second most important part of the system is libc. On MIPS we use
the GNU which has the enormous advantage of being far more portable and
cleaner code than the Linux Libc on which most Linux/i386 systems are
based. Disadvantage is that GNU libc was much buggier than Linux Libc.
This has changed a lot and so libc presents itself already quite near
to a release (*) libc but there is still some work to do.
Similar for the other core parts of the system on which David worked but
right now I'm still busy merging the kernel sources; the next step will
be libc.

:Hi
:
:we don't have a spare Indy to play with, but have a
:spare Challenge S (single processor R5000)
:
:I was wondering if you thing this machine is possible, it would be
:used with a serial console (no X), for testing ;)
:--
If you feel up to the challenge, sure, please go ahead.
There may be a few assumptions in the current code which detects
the newport graphics console that this testing may uncover. If
you can fix this so it won't be Indy dependent, we win one more
possible platform !
Moreover, since a challenge-S doesn't have graphics anyway
Linux which is fast and compact may even outperform IRIX
on some benchmarks.
I would suggest that:
1) You join the mailing list:
To: majordomo@engr.sgi.com
Body: subscribe linux your@preferred.email.address
if you have questions, ask...
2) If you have Challenge-S patches, e-mail them to the list
and we can check that they didn't break anything and
merge them into the source tree.

Peace, Ariel
