DAT and a couple more of the wd33c93 driver options available via the kernel command line. I wouldn't wonder if a CDROM or second disk results in the same sick effects.

The problems seems to be associated with either sync SCSI or disconnect/ reconnect. I did a two line modification to sgiwd93.c which disables sync and disconnect/reconnect.

It will misstreat VCEI exceptions. My idea is based on that we write the wrong cache line back, and that's why we receive the invalid instruction errors. Maybe this is foolish, but anyway: If we have data from main memory cached in the secondary cache and then overwrite that data line in main memory with an instruction line and cache the instruction. We receive a VCEI when we try to access the cached line, and our handler writes the data back instead of the intstruction and causes the invalid instructions. Well, this is the only idea I have at the moment. - Ulf From owner-linux@cthulhu.engr.sgi.com Fri Sep 4 09:04:40 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id JAA81080 for ; Fri, 4 Sep 1998 09:04:40 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id JAA96006 for linux-list; Fri, 4 Sep 1998 09:03:56 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from sguk.reading.sgi.com (sguk.reading.sgi.com [144.253.64.2]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via SMTP id JAA87427 for ; Fri, 4 Sep 1998 09:03:53 -0700 (PDT) mail_from (leon@reading.sgi.com) Received: from wintermute.reading.sgi.com (wintermute.reading.sgi.com [144.253.74.171]) by sguk.reading.sgi.com (950413.SGI.8.6.12/950213.SGI.AUTOCF+cray) via ESMTP id RAA25700 for <@sguk.reading.sgi.com:linux@cthulhu.engr.sgi.com>; Fri, 4 Sep 1998 17:03:52 +0100 Received: from localhost (localhost [127.0.0.1]) by wintermute.reading.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via SMTP id RAA32592 for ; Fri, 4 Sep 1998 17:03:49 +0100 (BST) Date: Fri, 4 Sep 1998 17:03:49 +0100 (BST) From: Leon Verrall To: SGI Linux Subject: Success at last...

The l2 cache on the indy CPU module is handled by the logic on the CPU _module_; the code to deal with that is being called by the *_pc functions and is in arch/mips/sgi/kernel/indy_sc.c.

Thinking about it the only real difference that I can think of was I had a keyboard/mouse installed. Before I was using a vt100 terminal.

I found that IRIX's tar wasn't very careful with modification dates, which I don't think is a problem, but the major and minor IDs of the dev files were all zero -- clearly broken.

Luckily we already have one which is called ``MAKEDEV''. As we already know the representation of the minor / major device number isn't transparent through NFS, so the MAKEDEV will have to detect the NFS server's OS and to corrospondingly munge the device number used as argument for mkdev in a way that after exporting from the NFS server the client sees what he expects to see. If that is at all possible in all cases. Yuck. But it's a longstanding problem which before has already been reported by people using other operating systems like HP/UX.

If that is You're 100% correct, hard coding the device on the fs is a BAD idea. However, a reasonable way of doing it is to just put the bare devices on the initrd, and create any additional devices you need. I'll do this in the next installer. - Alex From owner-linux@cthulhu.engr.sgi.com Fri Sep 11 10:55:25 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id KAA08419 for ; Fri, 11 Sep 1998 10:55:24 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id KAA21807 for linux-list; Fri, 11 Sep 1998 10:54:19 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from sgi.sgi.com (sgi.engr.sgi.com [192.26.80.37]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id KAA11829 for ; Fri, 11 Sep 1998 10:54:16 -0700 (PDT) mail_from (adevries@engsoc.carleton.ca) Received: from lager.engsoc.carleton.ca (lager.engsoc.carleton.ca [134.117.69.26]) by sgi.sgi.com (980327.SGI.8.8.8-aspam/980304.SGI-aspam: SGI does not authorize the use of its proprietary systems or networks for unsolicited or bulk email from the Internet.) via ESMTP id KAA01870 for ; Fri, 11 Sep 1998 10:54:15 -0700 (PDT) mail_from (adevries@engsoc.carleton.ca) Received: from localhost (adevries@localhost) by lager.engsoc.carleton.ca (8.8.7/8.8.7) with SMTP id NAA03646 for ; Fri, 11 Sep 1998 13:56:16 -0400 X-Authentication-Warning: lager.engsoc.carleton.ca: adevries owned process doing -bs Date: Fri, 11 Sep 1998 13:56:16 -0400 (EDT) From: Alex deVries To: SGI Linux Subject: newport questions...

The idea is that you specify only one Y, and two X's. Sometimes you don't specify a second X, but iterate writing 32-bit dither patterns till you are done. Note that you can do the same thing with lines, but you have to specify all of x0,y0,x1,y1. > - is the usable area *really* 5439x5120 pixels? this strikes me as > incredibly fine ( from page 26) > No. The address of the last pixel that corresponds to memory is that (more or less). Top left is 4096,4096. Add 1280,1024 to it you get: 5376,5120. Add 85 pixels of extra memory to the right of 5376 and you get 5461. So the last addressable pixel is 5460,5120 (my version of the doc has 5460 not 5439). The usable screen is really only between 4096,4096 and 5376,5120. > - can someone give me a moron's guide to what an iterator is? > You start from x0,y0. Eventually you have to get to x1,y1. The iterators add a dx,dy to each x,y (starting from x0,y0) that eventually gets you to x1,y1. Each clock tick of the iterator produces a new x,y and therefore a new pixel.

What is Linux/MIPS? XXX Add some general blurb, maybe move into abstract. 2. What hardware does Linux/MIPS support? 2.1. Hardware platforms Many machines are available with a number of different CPU options of which not all are currently are supported. Please check section ``Processor Type'' to make shure your CPU type is supported. 2.1.1. Silicon Graphics Indy The Indy is currently the only (mostly) supported Silicon Graphics machine. 2.1.2. Silicon Graphics Challenge S This machine is very similar to the Indy; it would therefore be a worthwile target for a hacker. What's missing is modifying the graphics card probing code such that it works in absence of a graphics card as this is the case on a headless machine like the Challenge S. 2.1.3. Silicon Graphics Indigo This machine is only being mentioned here because occasionally people have confused it with Indys. The Indigo series is a different architecture however and therefore yet unsupported. 2.1.4. Motorola 68k based machines like the Iris 3000 These are very old machines, probably more than ten years old by now. As these machines are not based on MIPS processors this document is the wrong place to search for information. However, in order to make things easy, these machines are currently not supported. 2.1.5. Other Silicon Graphics machines At this time no other Silicon Graphics machine is supported. This also applies to the very old Motorola 68k based systems. 2.1.6. SNI RM200C In contrast to the RM200 (see below) this machine has EISA and PCI slots. The RM200 is supported with the exception of the availability of the onboard NCR53c810A SCSI controller. 2.1.7. SNI RM200 If your machine has both EISA and PCI slots, then this is a RM200C, please see above. Due to the slight architectural differences of the RM200 and the RM200C this machine isn't currently supported in the official sources. Michael Engel engel@numerik.math.uni-siegen.de has managed to get his RM200 working partially but the patches haven't yet be included into the official Linux/MIPS sources. 2.1.8. Algorithmics P4032 (XXX Bash Ralf and Michael to finish this ... XXX) 2.1.9. DECstation series XXX Could some DECy write something for this? XXX 2.1.10. Mips Magnum 4000 / Olivetti M700-10 These two machines are both almost completely identical. Back during the ACE initiative Olivetti licensed the Jazz design and marketed the machine with Windows NT as OS. MIPS Computer Systems, Inc. itself bought the Jazz design and marketed it as the MIPS Magnum 4000 series of machines. Magnum 4000 systems were marketed with Windows NT and RISC/os as operating systems. Depending from the operating system which was installed on the machine a different firmware was installed on the box. Linux/MIPS supports only the little endian firmware on these two types of machines. Since the M700-10 was only marketed as NT machine all M700-10 machines have this firmware installed. The MIPS Magnum case is somewhat more complex. If your machine has been configured big endian for RISC/os then you need to reload the little endian firmware. This firmware was originally included with the delivery of every Magnum on a floppy. If you don't have the floppy anymore you can download it via anonymous ftp from . Note that the little endian firmware does not support headless operation. So if your machine does not include the standard G364 graphics card, your machine cannot boot. 2.1.11. MIPS Magnum 4000SC The Mips Magnum 4000SC is just the same as an Magnum 4000 (see above) with the exception that it's using a R4000SC CPU which currently is not supported by Linux. 2.2. Processor types 2.2.1. R2000, R3000 family The R2000 is the original MIPS processor. It's a 32 bit processor which was clocked at 8MHz back in '85 when the first MIPS processors came to the market. Later versions were clocked faster. The R3000 is a redesign of the R2000 which is 100% compatible, it was just again clocked faster. Because of the high compatibility this document usually only mentions the R3000 even though the same facts in most cases also apply for the R2000. Same also applies for the R3000 which basically a R3000 plus a R3010 FPU and 64k cache running at upto 40Mhz and integrated into same chip. Support for the R3000 processor is currently in the works by various people. Harald Koerfgen harald.koerfgen@netcologne.de and Gleb O. Raiko raiko@niisi.msk.ru have both indepentently worked on patches which however haven't yet been integrated into the official Linux/MIPS sources. 2.2.2. R6000 Sometimes people confuse the R6000, a MIPS processor, with RS6000, a series of workstations made by IBM. So if you're reading this in hope to find out more about Linux on IBM machines you're reading the wrong document. The R6000 is currently not supported. It is a 32 bit MIPS ISA 2 processor and a pretty interesting and wiered piece of silicon. It was developed and produced by a company named BIT Technology. Later NEC took over the semiconductor production. It was built in ECL technology, the same technology that was and still is being used to build extremly fast chips like those used in some Cray computers. The processor had it's TLB implemented as part of the last couple of lines of the external primary cache, a technology called TLB slice. That means it's MMU is substancially different from those of the R3000 or R4000 series which also is one of the reasons why the processor isn't supported. 2.2.3. R4000 and R5000 family Linux supports many of the members of the R4000 family, currently these are R4000PC, R4400PC, R4300, R4600, R4700, R5000, R5230, R5260. Many others are probably working as well. Not supported are R4000SC, R4000MC, R4400SC and R4400MC CPUs as well as R5000 systems with a CPU controlled second level cache. This means where the cache is controlled by the R5000 itself in contrast to some external external cache controller. The difference is important because unlike to other systems, especially PCs, on MIPS the cache is archtecturally visible and needs to be controlled by software. Ulf Carlsson grim@zigzegv.ml.org and Ralf Baechle ralf@gnu.org are currently working on support for R4000SC and R4400SC. 2.2.4. R8000 The R8000 is currently unsupported partly because the machines used by the Linux/MIPS developers don't have such a machine, partly because this processor is relativly rare and has only been used in a few SGI machines. The R8000 is a pretty interesting piece of silicon. Unlike the other members of the MIPS family it is a set of seven chips. It's cache and TLB architecture is pretty different from the other members of the MIPS family. It was born as a hack in order to get the floating point crown back to Silicon Graphics in time before the R10000 is finished. 2.2.5. R10000 The R10000 is currently unsupported because the machines used by the Linux/MIPS developers don't have such a machine. 2.3. Drivers 3. Is there a Linux distribution? 3.1. RedHat XXX Add some gossip about HardHat aka Rough Cuts XXX. 3.2. What about other distributions? 4. Where can I get Linux/MIPS from? 5. Installation of Linux/MIPS. 6. How do I setup a crosscompiler? First of all go and download the following source packages: XXX Incomplete, maybe tell'em to get the files from the srpm packages? XXX o binutils-2.8.1.tar.gz o egcs-1.0.2.tar.gz o glibc-2.0.6.tar.gz o glibc-crypt-2.0.6.tar.gz o glibc-localedata-2.0.6.tar.gz o glibc-linuxthreads-2.0.6.tar.gz These are the currently recommended versions. Older versions may or may not be working. If you're trying to use older versions please don't send bug reports, we don't care. When installing please install things in the order binutils, egcs, then glibc. Unless you already have older versions already installed changing the order will fail. 6.1. Diskspace requirements For the installation you'll have to choose a directory for installation. I'll refer to that directory below with . To avoid a certain problem best just the same value for as your native gcc. For example if your gcc is installed in /usr/bin/gcc then choose /usr for . You must use the same value for all the packages that you're going to install. During compilation you'll need about 31mb diskspace for binutils. For installation you'll need 7mb diskspace for binutils on 's partition. Building egcs requires 71mb and installation 14mb. GNU libc requires 149mb diskspace during installation and 33mb for installation. Note these number are just a guideline and may differ significantly for different processor and operating system architectures. 6.2. Byte order On of the special features of the MIPS architecture is that all processors except the R8000 can be configured to run either in big or in little endian mode. Byte order means the way the processor stores multibyte numbers in memory. Big endian machines store the the byte with the highest value digits at the lowest address while little endian machines store it at the highest address. Think of it like writing multi digit numbers from the left to the right or visa versa. In order to setup your crosscompiler correctly you have to know the byte order of the crosscompiler target. If you don't know already know, check the section ``Hardware Platforms'' for your machine's byteorder. 6.3. Configuration names Many of the packages based on autoconf are supporting many different architectures and operating systems. In order to differenciate between these many configurations names madeup like -- or even ---. Expressed that way the configuration names of Linux/MIPS are mips-unknown-linux- gnu for big endian targets or mipsel-unknown-linux-gnu for little endian targets. Those names are a bit long and so it's allowed to abreviate them to mips-linux or mipsel-linux. You must use the same configuration name for all the packages that your crosscompilation environment consists of. Also, while other names like mips-sni-linux or mipsel-sni-linux are both legal configuration names, don't use them but only mips-linux or mipsel-linux. The reason is that other packages like the Linux kernel sources know about these configuration names and you'd have to change them for crosscompilation. I'll refer to the target configuration name below with . 6.4. Installation of GNU Binutils. This is the first and most simple part - at least as long as you're trying to install on any halfway sane UNIX flavour. Just cd into a directory with enough free space and do the following: gzip -cd binutils-.tar.gz | tar xf - cd binutils- patch -p1 < ../binutils--mips.patch ./configure --prefix= --target= make CFLAGS=-O2 make install This usually works very easily. On certain machines using GCC 2.7.x as compiler is known to dump core. This is a known bug in GCC and can be fixed by upgrading to GCC 2.8.1 or egcs. 6.5. Assert.h Some people have an old assert.h headerfile installed, probably a leftover from an old crosscompiler installation. This file may cause autoconf scripts to fail silently. It was never necessary and only got installed due to a bug in older GCC versions. Check if //include/assert.h exists in your installation. If so, just delete it. 6.6. First installation of egcs Now the not so funny part begins. There is a so called bootstrap problem. In our case that means the installation process of egcs needs an already installed glibc. But we cannot yet compile glibc because we don't have a working crosscompiler yet. Luckily you'll only have to go through this once when you install a crosscompiler for the first time. Later when you already have glibc installed things will be much smoother. So now do: gzip -cd egcs-.tar.gz | tar xf - cd egcs- for i in egcs-1.0.2-libio.patch egcs-1.0.2-hjl.patch \ egcs-1.0.2-rth1.patch egcs-1.0.2-rth2.patch egcs-1.0.2-rth3.patch \ egcs-1.0.2-rth4.patch egcs-1.0.2-hjl2.patch egcs-1.0.2-jim.patch \ egcs-1.0.2-haifa.patch egcs-1.0.1-objcbackend.patch \ egcs-1.0.2-mips.patch; do patch -p1 -d < ../$i; done ./configure --prefix= --with-newlib --target= cd gcc make LANGUAGES="c" Note that we deliberately don't build gcov, protoize, unprotoize and the libraries. Gcov doesn't make sense in a crosscompiler environe- ment and protoize and unprotoize might even overwrite your native pro- grams - this is a bug in the gcc makefiles. Finally we cannot yet build the libraries because we don't have glibc installed yet. If everything went successful install with: make LANGUAGES="c" install 6.7. float.h Another, bootstrap problem is that building GCC requires running programs on the machine that GCC will generate code for. But since a crosscompiler is running on a different type of machine this cannot work. When buiding GCC this happens for the header file float.h. Luckily there is a simple solution. Download the header file from one of the Linux/MIPS ftp servers or rip it from one of the native Linux/MIPS binary packages. Later when recompiling or upgrading egcs usually the already installed float.h file will do because float.h changes rarely. Install it with: cp float.h //include/float.h where is the internal version number of the egcs version you're using. For egcs 1.0.2 for example you would put egcs-2.90.27 for . If not shure - ls is your friend. 6.8. Installing the kernel sources XXX Write some simple shit for nobrainers. If you only want the crosscompiler for building kernel you're done. 6.9. Installing GNU libc Do: gzip -cd glibc-2.0.6.tar.gz | tar xf - cd glibc-2.0.6 gzip -cd glibc-crypt-2.0.6.tar.gz | tar xf - gzip -cd glibc-localedata-2.0.6.tar.gz | tar xf - gzip -cd glibc-linuxthreads-2.0.6.tar.gz | tar xf - patch -p1 < ../glibc-2.0.6-mips.patch mkdir build cd build CC=-gcc BUILD_CC=gcc AR=-ar RANLIB=-ranlib \ ../configure --prefix=/usr --host= \ --enable-add-ons=crypt,linuxthreads,localedata --enable-profile make You now have a compiled GNU libc which still needs to be installed. Do not just type make install. That would overwrite your host sys- tem's files with Linux/MIPS specific files with desasterous effects. Instead install GNU libc into some arbitrary other directory from which we'll move the part's we need for crosscompilation into the actual target directory: make install_root= install Now cd into and install finally install GNU libc manually: cd usr/include find . -print | cpio -pumd //include cd ../../lib find . -print | cpio -pumd //lib cd ../usr/lib find lib -print | cpio -pumd //lib GNU libc also contains extensive online documentation. Your systems might already have a version of this documentation installed. So if you don't want to install the info pages which will save you a less than a megabyte or already have them installed skip the next step: step: cd ../info gzip -9 *.info* find . -name \*.info\* -print | cpio -pumd /info If you're not bootstrapping you're installation is now finished. 6.10. Building egcs again The first attempt of building egcs was stopped by a not yet existent GNU libc. Since we now have libc installed we can rebuild egcs but this time as complete as a crosscompiler installation can be: gzip -cd egcs-.tar.gz | tar xf - cd egcs- for i in egcs-1.0.2-libio.patch egcs-1.0.2-hjl.patch \ egcs-1.0.2-rth1.patch egcs-1.0.2-rth2.patch egcs-1.0.2-rth3.patch \ egcs-1.0.2-rth4.patch egcs-1.0.2-hjl2.patch egcs-1.0.2-jim.patch \ egcs-1.0.2-haifa.patch egcs-1.0.1-objcbackend.patch \ egcs-1.0.2-mips.patch; do patch -p1 < ../$i; done ./configure --prefix= --target= make LANGUAGES="c c++ objective-c f77" As you can see the procedure is the same as the first time with the exception that we dropped the --with-newlib option. This option was necessary to avoid the libgcc build breaking due to the not yet installed libc. Now install with: make LANGUAGES="c c++ objective-c f77" install You're almost finished. All you'll now still have to do is to rein- stall float.h which has been overwritten by the last make install com- mand. You'll have to do that every time you reinstall egcs as a crosscompiler. If you think you don't need the Objective C or F77 compilers you can omit them from above commands. Each will save you about 3mb. However don't build gcov, protoize and unprotoize. 6.11. Should I build the C++, Objective C or F77 compilers? The answer to this question largely depends on your use of your crosscompiler environment. If you only intend to rebuild the Linux kernel then you have no need for the full blown setup and can safely omit the Objective C and F77 compilers. You however must build the C++ compiler because building the libraries included with the egcs distribution are written in C++. --OXfL5xGRrasGEqWY-- From owner-linux@cthulhu.engr.sgi.com Tue Sep 22 14:13:32 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id OAA83295 for ; Tue, 22 Sep 1998 14:13:32 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id OAA01793 for linux-list; Tue, 22 Sep 1998 14:12:37 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from sgi.com (ripple.nashua.sgi.com [169.238.59.194]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id OAA66457; Tue, 22 Sep 1998 14:12:35 -0700 (PDT) mail_from (lembree@sgi.com) Message-ID: <3608103B.6F2844E2@sgi.com> Date: Tue, 22 Sep 1998 17:01:47 -0400 From: Rob Lembree Organization: Silicon Graphics, Inc.

I've untarred the hardhat distr. on my linux machine and that's the machine that plays nfs server for the challenge. Should the default kernel support serial terminal consoles?? My goal is to install linux onto the challenge (which is headless) using a serial terminal connected to it, is this possible by default or should i cross-compile my own kernel on another platform?.

Rich, First, I wonder how much of the kernel will actually work on the Challenge S; I'm told there are SCSI controller differences. The install kernel you're using (and oh god, is it ever a bad one) is broken in that serial console won't work. Yes, I should have looked into it way back when. There's two things you can do: - rebuild a kernel by cross compiling in the correct options (this is reasonably easy to do) - wait for me to have my machine moved (finally) and online and I'll whip up a modern install kernel for you and the others with serial console Just to reiterate, yes, I *will* be fixing the install. The initrd stuff is going to have to make it in, even if it kills me. And I'll be working on porting Rawhide 1.0 too. - Alex From owner-linux@cthulhu.engr.sgi.com Wed Sep 23 12:53:08 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id MAA34873 for ; Wed, 23 Sep 1998 12:53:08 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id MAA99255 for linux-list; Wed, 23 Sep 1998 12:52:28 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from sgi.sgi.com (sgi.engr.sgi.com [192.26.80.37]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id MAA54805 for ; Wed, 23 Sep 1998 12:52:26 -0700 (PDT) mail_from (sgi.sgi.com!rachael.franken.de!hub-fue!alpha.franken.de!tsbogend) Received: from rachael.franken.de (rachael.franken.de [193.175.24.38]) by sgi.sgi.com (980327.SGI.8.8.8-aspam/980304.SGI-aspam: SGI does not authorize the use of its proprietary systems or networks for unsolicited or bulk email from the Internet.) via ESMTP id MAA08985 for ; Wed, 23 Sep 1998 12:52:24 -0700 (PDT) mail_from (rachael.franken.de!hub-fue!alpha.franken.de!tsbogend) Received: from hub-fue by rachael.franken.de via rmail with uucp id for cthulhu.engr.sgi.com!linux; Wed, 23 Sep 1998 21:52:16 +0200 (MET DST) (Smail-3.2 1996-Jul-4 #4 built DST-Sep-8) Received: by hub-fue.franken.de (Smail3.1.29.1 #35) id m0zLuxL-002OwLC; Wed, 23 Sep 98 21:52 MET DST Received: (from tsbogend@localhost) by alpha.franken.de (8.8.7/8.8.5) id VAA02085; Wed, 23 Sep 1998 21:22:41 +0200 Message-ID: <19980923212241.01963@alpha.franken.de> Date: Wed, 23 Sep 1998 21:22:41 +0200 From: Thomas Bogendoerfer To: Alex deVries Cc: Richard Hartensveld , Rob Lembree , linux@cthulhu.engr.sgi.com Subject: Re: challenge s boots linux References: <36081982.8D3B6975@infopact.nl> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.85 In-Reply-To: ; from Alex deVries on Tue, Sep 22, 1998 at 08:24:20PM -0400 Sender: owner-linux@cthulhu.engr.sgi.com Precedence: bulk Content-Length: 1157 Lines: 25 On Tue, Sep 22, 1998 at 08:24:20PM -0400, Alex deVries wrote: > First, I wonder how much of the kernel will actually work on the > Challenge S; I'm told there are SCSI controller differences. looking linus.linux.sgi.com, which is AFAIK a Challenge S, it seems the Challenge has a wd33c93 and a wd33c95. The wd33c93 is what we already support. As long as the harddisk are attached to it, it should work. The wd33c95 is a rather strange chip, and from the datasheet I have here, it looks like a lot of work to write a driver for it, because besides the kernel code, you have to write sequence code for the chip, too. > The install kernel you're using (and oh god, is it ever a bad one) > is broken in that serial console won't work.

This is an interesting question, and I for one would much rather see things like the graphics for Newport and audio working on the INdy before we start off on other things like the Indigo2. But, i've been thinking for awhile that an Indigo2 port would be the next box to target... i suppose there's no harm in looking at both machines concurrently. Getting docs on the Indigo2 would be quite important for a successful port, though. That would require SGI's help, and I can see them being a lot more open to it if we got the Indy completely supported first. - Alex From owner-linux@cthulhu.engr.sgi.com Thu Sep 24 09:46:37 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id JAA99397 for ; Thu, 24 Sep 1998 09:46:37 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id JAA25998 for linux-list; Thu, 24 Sep 1998 09:45:08 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from fir.engr.sgi.com (fir.engr.sgi.com [150.166.49.183]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via SMTP id JAA97917; Thu, 24 Sep 1998 09:45:04 -0700 (PDT) mail_from (wje@fir.engr.sgi.com) Received: (from wje@localhost) by fir.engr.sgi.com (950413.SGI.8.6.12/950213.SGI.AUTOCF) id JAA13188; Thu, 24 Sep 1998 09:44:53 -0700 Date: Thu, 24 Sep 1998 09:44:53 -0700 Message-Id: <199809241644.JAA13188@fir.engr.sgi.com> From: "William J.

They run the same IRIX kernel binary. The graphics are more of an issue, since most Indigo2 systems use something other than Newport ("XL") graphics. It might be possible for Linux to get by using the very basic microcode downloaded by the PROM for XZ and other microcoded graphics cards, but I have not had time to research the interface presented. There is general willingness to release information, although releasing Indigo2-specific information would require a new authorization. The main problem is finding it in a form useful to people outside SGI. (That is not true for all hardware, but it is for quite a few of our older systems.) The easiest path would be if someone inside SGI cobbled up basic sample drivers for the various graphics cards, but so far there are no volunteers. (The reason it would be the easiest path is that SGI employees can use the IRIX source as a guide.)

I thought they wer pretty much all the same. There are two big differences between ours: - 32 MB appears somehow just not to be enough to operate well. I don't know where the memory is actuall ygoing, though. - There must be two different screen resolutions, since the *exact* same binaries that displayed beautifully on mine were chopped off on Mike's.

Okay. So there's a partitioning issue. I think we knew that. The script execution thing is, i think, just because the CD you have isn't quite the latest one. > Kernel notes: I also get the truncated screen reported by Jan Chadima > (and Leon Verrall?); it seems like at least ten lines scrolling out of > view.

If I'll try it on a R4600PC Indy or a R4000PC Olivetti with Linux, I don't get what I would expect. On IRIX, Linux/Alpha (I have to change the offset between the two mapping to 0x2000, because of the bigger page size on Alphas) and Linux/x86 the program works.

No, IRIX does write ownership switching, using the TLB. That is, only one virtual cache color (virtual cache page index) equivalence class of mappings can have the hardware PTE valid bit set at any one time, if any class has the hardware PTE modify bit set in any of its PTEs. If no class has the modify bit set in any PTE, then all classes may have the PTE valid bit set. If you want to read via class (color) 0, and the class 1 is currently writing, all PTEs of class 1 have the modify bit turned off, and the primary data cache for class 1 is written back to memory (and is hence marked "clean" instead of "dirty" in the cache). Class 0 is then allowed to read (the hardware valid bit is set in the faulting PTE). If class 0 wants to write (gets a modify fault), the valid bit is turned off for all PTEs of other classes, and the data cache for those classes is invalidated with respect to the page in question, and then the modify bit is turned on for the faulting PTE. Note that this problem applies to the R4000PC and to all R4600 and R5000 processors (PC and SC), because there is no hardware VCE support in those processors. Software must avoid allowing virtual aliases of different colors to write concurrently, and must writeback-invalidate the cache for the old color and invalidate the PTEs for the old color, when allowing some other color to write. Doing this efficienly requires some form of back pointer from the page frame table entry for the page to all of the virtual references for the page (the PTEs). IRIX does not need to do this for anonymous pages, since they cannot be double-mapped with different virtual colors. It uses the vnode pointer in the page frame table to the list of mappings for the page; the analog in linux is inode field in mem_map_t, which points to the mapped file, which in turn points to the mappings via i_mmap and the vm_next_share/vm_pprev_share pointers. Note further that this problem is complicated by the MIPS K0SEG addressing mode. Since there are no PTEs for K0SEG, the kernel should not use K0SEG addresses for pages which may be mapped into user space with multiple colors. IRIX makes an effort to minimize conflicting mappings, by arranging that the default address selected for mmap() is color-congruent to the offset in the file being mapped. This of course does not work for MAP_FIXED, so MAP_FIXED requires the above write ownership switching. The ownership can be provided by a field in mem_map_t of 5 bits: int vcolor : 5; Where we define: #define PAGE_VCOLOR_MIN 0 #define PAGE_VCOLOR_MAX 7 #define PAGE_VCOLOR_NONE (-2) #define PAGE_VCOLOR_SHARED (-1) and #define PAGE_IS_VCOLOR_EXCLUSIVE(mm) ((mm)->vcolor >= 0) #define PAGE_IS_VCOLOR_SHARED(mm) ((mm)->vcolor == PAGE_VCOLOR_SHARED) We also have extern int pagevcolorsize; extern int pagevcolormask; #define vaddr_to_vcolor(va) ((((__psunsigned_t) (va)) / NBPP) & pagevcolormask) We set pagecolorsize to the size of one set of the cache divided by the size of a page, and we set pagecolormask to (pagecolorsize - 1). For the R4000PC and R4600, pagecolorsize is 2; for the R5000, pagecolorsize is 4. Note that the virtual color on the R4000SC and R4400SC has 8 values, regardless of the primary cache size, for a page size of 4 KB, because the secondary cache treats the 8 possible values of the PIdx field of the secondary cache tag as distinct.

Basically a good solution requires a way to map a page's physical address to virtual addresses. And Linux 2.2's mm will not provide this feature. Reverse mappings are under planning for 2.3 for other improvments. It was my plan to ignore this bug for now and deal with virtual coherency when reverse mappings are implemented in 2.3. Oh, I've already implemented the solution for the special case of ZERO_PAGE. On CPUs which know about the virtual coherency exception have eight colours for zero page. The change is basically to pass in the virtual address to ZERO_PAGE such that we always do ``colourly correct'' allocation. That was the simple case. > How does IRIX solve this problem ? Does it disable caching for shared > writeable pages ? Mapping shared writeable pages uncached is not the solution. The virtual coherency problem in Linux/MIPS may happen between multiple userspace mappings or userspace and kernelspace, that is KSEG0, mappings. While we could disable caching for certain pages in the hope that we'll only end up with a few uncached pages making KSEG0 uncached is completly unacceptable performancewise. However, if we don't, then we might end up with aliases between userspace pages and KSEG0 pages.

On the machines without VCE detection (R4000PC, R4600, R5000), the zero page is safe, because it is read-only. Anonymous pages are not an issue, since they are not double-mapped. What is wrong with going from the mem_map_t.inode to the inode.i_mmap list of mappings, and thence to the PTEs? IRIX, at least before IRIX 6.5, does the equivalent to solve this problem. > > How does IRIX solve this problem ?

IRIX mostly does that, and keeps the KSEG2 mapping around only as long as necessary, and then only with the current virtual color (the color which currently has write ownership of the page) locked (which means that references via other colors block until the kernel gives up its mapping).

And I've already arranged with the folks in Atlanta to get me a monitor so that I can bring my little blue fellow down to put SGI/Linux on display. In other news, I have in my possesion 15 copies of Rough Cuts, on which disk 3 is the hardhat release we worked on. - Alex From owner-linux@cthulhu.engr.sgi.com Wed Sep 30 14:31:39 1998 Received: from cthulhu.engr.sgi.com (cthulhu.engr.sgi.com [192.26.80.2]) by neteng.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id OAA96594 for ; Wed, 30 Sep 1998 14:31:39 -0700 (PDT) Return-Path: Received: (from majordomo-owner@localhost) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) id OAA26022 for linux-list; Wed, 30 Sep 1998 14:29:51 -0700 (PDT) mail_from (owner-linux@relay.engr.sgi.com) Received: from sgi.sgi.com (sgi.engr.sgi.com [192.26.80.37]) by cthulhu.engr.sgi.com (980427.SGI.8.8.8/970903.SGI.AUTOCF) via ESMTP id OAA38277 for ; Wed, 30 Sep 1998 14:29:49 -0700 (PDT) mail_from (ralf@uni-koblenz.de) Received: from mailhost.uni-koblenz.de (mailhost.uni-koblenz.de [141.26.4.1]) by sgi.sgi.com (980327.SGI.8.8.8-aspam/980304.SGI-aspam: SGI does not authorize the use of its proprietary systems or networks for unsolicited or bulk email from the Internet.) via ESMTP id OAA07164 for ; Wed, 30 Sep 1998 14:29:44 -0700 (PDT) mail_from (ralf@uni-koblenz.de) Received: from uni-koblenz.de (pmport-16.uni-koblenz.de [141.26.249.16]) by mailhost.uni-koblenz.de (8.9.1/8.9.1) with ESMTP id XAA06542 for ; Wed, 30 Sep 1998 23:29:37 +0200 (MET DST) Received: (from ralf@localhost) by uni-koblenz.de (8.8.7/8.8.7) id XAA01110; Wed, 30 Sep 1998 23:29:40 +0200 Message-ID: <19980930232939.E770@uni-koblenz.de> Date: Wed, 30 Sep 1998 23:29:39 +0200 From: ralf@uni-koblenz.de To: Richard Hartensveld , "linux@cthulhu.engr.sgi.com" Subject: Re: crosscompiling on debian/i386 References: <36116D45.E34A6FEF@infopact.nl> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.91.1 In-Reply-To: <36116D45.E34A6FEF@infopact.nl>; from Richard Hartensveld on Wed, Sep 30, 1998 at 01:29:09AM +0200 Sender: owner-linux@cthulhu.engr.sgi.com Precedence: bulk Content-Length: 676 Lines: 16 On Wed, Sep 30, 1998 at 01:29:09AM +0200, Richard Hartensveld wrote: > i'm trying to crosscompile a linux/sgi kernel on a debian/i386 machine > with the binutils and the mips-linux-gcc compiler from the linux-sgi ftp > site. > > But i keep getting the following error, does anyone know what i am > doing wrong.? The error messages look like you've been attempting to compile a vanilla kernel from ftp.kernel.org. Won't work, get a tree from ftp.linux.sgi.com. You're also passing variables to make which normally isn't necessary. Did you've select CONFIG_CROSSCOMPILE when configuring the kernel? The sources will then automatically select the right compiler.
