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.

The idea basically is that we will be > getting a machine each one to finish the Linux on SGI port. 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.

Basically we need to mkfs.ext2(8) on the local Indy (as IRIX supports XFS and EFS both of which are proprietary, Sigh) It would be best to have a seprate disk (rather than a partition which may disappear in case of human error) Get SILO to work, get the latest gcc to work native and we can start working on userland. In all actuality I did have real Linux ext2 filesystems on my test box, only the kernel was network obtained. In fact the stock ext2 filesystem utilities can be compiled on non-Linux platforms out of the box, they use GNU autoconf. In fact this is what I did to get going initially. I still had to use IRIX fdisk to label the disk, but then from IRIX I just ran the mke2fs program to make the ext2 filesystem. Then I'd boot Linux quickly using nfsroot, mount the ext2 filesystem I had just created, and I constructed a partition by copying files over from the nfs partition in this way. It was a pain, but it worked and I was more interested in seeing results than doing it right at the time. ;-) Also the rapid pace at which I was making changes to libc which caused all of the binaries on the partition to be unusable (because of a change of symbols in the dynamic linker etc.) actually warranted this scheme. A boot loader is really needed though. There are essentially two or three approaches most ports take to this task: 1) If the machine provides a "BIOS" or ROM interface that the loader can use to access the raw disk to do I/O operations, the boot loader only needs to be very minimal. It uses the ext2 filesystem library, teaches the library at init time to use functions which it provides to do I/O. It will do so via the ROM interfaces. Also, some knowledge of the disk labeling scheme is necessary as well. This is the scheme used by the Sparc port's boot loader, it is the easiest way to approach this problem and it does not lack any features. 2) The Alpha port sticks essentially a miniature kernel into the boot loader. Although I dislike this scheme, I have been told that they do need to do things this way. Pretty much the boot loader has full device drivers in it. I'd suggest scheme 1, I am nearly positive the SGI proms provide all the facilities necessary to do what I have described. And if I remember correctly the boot loader that Ralf is using on his SRM machines does in fact do all of this. It would be beneficial to go and look at the available boot loaders already coded, I have a sneaking suspician that someone willing to stare at all of the code in those boot loaders can get the thing working on an INDY in say 5 or 6 days time with no prior knowledge. Asking David some questions might be a good idea too. I'm not sure he is currently on the list, I'll ask him if he's interested to join. If I am not on there now, please add me. I'll listen in. Larry and I are working on setting up linux.sgi.com outside the SGI firewall. My intention is to set up tcpwrappers so that only the developers (Ralf, Miguel, Mike) and SGI people could login and give you complete control of the machine. At which point you can install ssh or whatever and start sharing sources. The "official" initial post-David merged source tree should come from Ralf.

Are you going to reactivate the linux-progress list...it was great to keep track of where things were at last time. 2. I'm not sure what root environment is sitting around in David's stuff, but in neteng.engr:~dm/alambie there are a bunch of files: root.tar.gz - Root filesystem contents with prebuilt devs, basic bin utilities and a shell. init.tar.gz - An init program and the basics to get multiuser mount.tar.gz - guess what..... e2fsprogs-IRIXprebuilt.tar.gz - The e2fsprogs that run under Irix to build an ext2 filesystem Don't know whether these are useful to any of the guys or not, but they may help them bootstrap to something use[able|ful]. These were built with Ralph's static libc stuff. 3. The original plan for userland that David was working towards was to use the packages from RedHat and set them up for Alpha (that way we get big endian and 64bit) and work from that as a base....I'm guessing that's still the best way. We felt at the time that the RedHat rpms seemed the best to go with as they have good support for handling multiple architecture's. 4. From memory David had done a heap of work on glibc as well as gcc. I think he was getting ral close to something that was almost useable...a lot of the problems seemed to be in the runtime linker for shared lib support. I'm wondering if any of the work Cygnus are doing will help here?? 5. Are we going to keep using CVS as a standard....we will definitely need some form of source control with so many people working on it!

For general references on assembly programming, I'm not sure. Is there a need for such a thing ? But for MIPS specific, if you've go an SGI with a proper development toolkit on it, it should come with an online book entitled "MIPS Assembly Programming Guide". That's quite a complete reference, but not a tutorial. The hacker way of looking at things (the one I like) is to write tiny C programs, compile them with cc -S, look at the output, and try to understand what happens. Even better, compile your c program and use dis (the sgi disassembler) to look at the result (cc -S output something that's not really the final thing the CPU groks) Also, dbx has quite a few command that allow you to follow a program step by step at assembly level: ni (next instruction, don't follow subroutine calls) si (next instruction, follow) stopi at (add an asm level breakpoint) syscall catch call xx (stop on system call xx) $pc-20/50i (list asm fragment around current PC) pr (dump registers) assign $pc=xxxx (change value of register pc to xxxx) etc ... Finally, beware of pipelining weirdies. A most striking example is: [ 4] 0x40092c: 03 e0 00 08 jr ra // Return from subroutine [ 4] 0x400930: 24 02 00 03 li v0,3 // Load return value in v0 At first reading, it seems like the routine returns before loading the return value in v0. Actually, both instructions are executed at the same time. - Mgix From owner-linux@cthulhu.engr.sgi.com Fri Mar 28 12:03:09 1997 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (950413.SGI.8.6.12/960327.SGI.AUTOCF) via ESMTP id MAA02751; Fri, 28 Mar 1997 12:03:08 -0800 Return-Path: Received: (from majordomo@localhost) by cthulhu.engr.sgi.com (950413.SGI.8.6.12/960327.SGI.AUTOCF) id MAA26457 for linux-list; Fri, 28 Mar 1997 12:02:48 -0800 Received: from gandalf.engr.sgi.com (gandalf.engr.sgi.com [150.166.61.44]) by cthulhu.engr.sgi.com (950413.SGI.8.6.12/960327.SGI.AUTOCF) via ESMTP id MAA26452 for ; Fri, 28 Mar 1997 12:02:46 -0800 Received: from localhost (jmp@localhost) by gandalf.engr.sgi.com (950413.SGI.8.6.12/960327.SGI.AUTOCF) via SMTP id MAA15285; Fri, 28 Mar 1997 12:02:39 -0800 Message-Id: <199703282002.MAA15285@gandalf.engr.sgi.com> X-Mailer: exmh version 1.6.2 7/18/95 To: linux@cthulhu.engr.sgi.com, pittet@base.sgi.com, ms@basel.sgi.com cc: jmp@gandalf.engr.sgi.com Subject: Info on the N64 port?
