Hi,

I've placed some snapshots and diffs of libc and the kernel in
ftp.linux.sgi.com:/pub/linux/mips/testing/.  The bug fixes in
the newest version are really important, apply them or switch
your Indy off ;-)

Hello guys,

   I am a little worried that probably it is not a good idea to just
copy shamelessly the structures and contant definitions from the
/usr/include/sys files for implementing the Linux GFX/RRM. 

   Right now I have included a "----BEGIN-COPY-PASTE----" and a
"----END-COPY-PASTE----" comments to my asm/gfx.h and my asm/rmm.h
noting explicitly where the stuff has just been copy and pasted and
not massaged, but I wonder if it is ok to merge this into the GPLed
Linux kernel.

   Comments?

cheers,
Miguel.

Hi all,

with my recent bug fixes the kernel/libc becomes again stable
enough to carry a reasonable userland.  I spent last night rebuilding
alot of RPM packages from RedBat 4.2.  Many of them built fine without
changes.  Top problems which prevented rebuilding I found are

 - bugs in the new VFS layer of 2.1.43
 - patch + glibc don't seem to work too well

(These two are the most annoying)

 - We don't have yet a (reliable) port of X.  Miguel de Icaza is working
   on that, especially on a X server for the Indy.
 - Neither RedHat nor any of the other availble distributions has a
   concept of bootstrapping out on a system where almost nothing is
   installed.  So it's an annoying game to find out which packages
   to build in which order ...
 - Static linking is currently broken.  Still many people use it as part
   of some kind of safety concept not noticing that a large fraction
   of userland programs will pull in the shared libraries vi the NSS
   mechanism anyway ...
 - On some configurations we still have problems with bad UDP/IP packets.
   This though I fixed a couple of endian bugs in the checksum code
   during the last days.  Right now it seems that the Indy and M700 (using
   NE2000) are not affected by the problem, while P4032 and RM200 spit
   a good number of bad packets.  Right now I guess we've got some other
   problem, maybe memory corruption.

I've grabbed Ralf's cpio'd super-root and now I have a native
compiler.

Some day, I'll figure you what was wrong with mine.  In the meantime,
I'm going to try to get the Indy booting off local disk, because the
NFS stuff is a little sloooooooow.

Hi,

the most current GCC package installs the header file assert.h although
it shouldn't.  The problem is that the GCC version of assert.h will
not include <gnu/stubs.h> but autoconf generated configure scripts
rely on that.  If you ever wondered why loading programs caused warnings
like 'the function lchown is not implemented and will always fail', this
is caused by the wrong assert.h.

Quick fix: rm <prefix>/<target>/include/assert.h, for example.
rm /usr/local/mipsel-linux/include/assert.h.  Note that this applies
to both native and crosscompilers.  None of them will install the
assert.h file in /usr/include/.

Hi all,

Just to a status report about the packages Miguel mentioned.  This is
from memory, so neither complete nor 100% accurate.  I've tried more
than just these ...

 - Programs work, not even tried to packaged into RPMs yet:
    binutils gcc glibc util-linux procps sh-utils MAKEDEV bash

 - Packaging failed but otherwise working:
    apache, ncurses, dev

 - Works as far as tested:

    net-tools setup

 - RPM package available but buggy:
    SysvInit statnet

 - Package doesn't build for unknown reasons:
    Emacs getty_ps e2fsprogs bdflush 

Since I'm developping offline I'm a bit lazy about merging other stuff
into my kernel.  With the VFS bug fixes a good couple more of packages
would build and work.

    - Package doesn't build for unknown reasons:
       Emacs getty_ps e2fsprogs bdflush 

Emacs should build strictly out of the box in an of itself, I know
because I specifically sent RMS patches for linux-mips support the
moment I got it working last summer with GLIBC.  (I even then logged
in to the gnu project machines and made sure those changes made it
into his tree ;-)

If it isn't compiling at all, tell me how it is failing.

Ok, special service for the Emacs people.  I'll check out why the RPM
didn't build.  I didn't care about that yet because my favourite
editor still is the prophet of Rock'n'Roll ...

Ok, I took a look at it.  The Emacs 19.34b does not contain the least
bit of support for mips{el}-linux, so no wonder why it doesn't build.
Can you send me your patches?  I assume RMS won't like it if we take
the Emacs snapshot from the FSF ...

Thanks,

  Ralf

Go into src/m/mips.h and grep for __linux__ it's in there.

Ok, looks like the mips-*-linux entry never made it into the top level
configure, the rest of the support code is in there though as
indicated by the __linux__ tests in mips.h

Yesterday I digged David's patches out of the FSF's Emacs archive.  It
builds and seems run without problems with these patches.  I just
had to hack 'em a bit to add support of little endian machines.

The problem with the e2fstutils not compiling out of the box turned
out to be a problem in the autoconf generated configure script.
Including <netinet/in.h> results in a warning and that again makes
the script assumes that we don't have <netinet/in.h> at all ...

I suspect that many people on this list will have read it already, but
those that haven't probably should. =)

It is an excellent piece.  The problem is that many will not
have the patience to read it since it is so long.

My internal "Why Linux/Freeware" web page at SGI has a pointer to
Eric Raymond's treatise (since David pointed it to me for which
I'm grateful).

To make it easier for more people to grasp I use to send
this short excerpt from the last part:

	No commercial developer can match the pool of talent the Linux
	community can bring to bear on a problem. Very few could afford
	even to hire the more than two hundred people who have contributed
	to fetchmail! [A freeware program maintained by Eric -- Ed] 

        Perhaps in the end the free-software culture will triumph not
	because cooperation is morally right or software "hoarding" is
	morally wrong (assuming you believe the latter, which neither
	Linus nor I do), but simply because the commercial world cannot
	win an evolutionary arms race with free-software communities that
	can put orders of magnitude more skilled time into a problem. 

We know this of course, now the big question is how to open the eyes
of our CEOs and high level managers (we're working on it).

To get a critical mass of SGI users installing/running linux
I believe we should aim at a setup where any non-guru could:

	1) Install a full Linux distribution over the net
	   (e.g. from linus.linux) from a running IRIX system
	   On a virgin (separate) SCSI disk.

	2) Once it is there, hot-start Linux from IRIX

If we do it this way, users will be able to keep IRIX
and it'll cost just an additional disk (a few hundred dollars)
to get Linux running on the systems they are already used to
work with.  Since they have little to lose or to risk this
way we have a much higher chance to get many users on board.

Tangentially related:
For those who don't know this, you may do a scheduled auto
power-off / power-on on IRIX:

        % su
        # at 5am July 3
        /usr/sbin/wakeupat 6pm Thursday
        /etc/shutdown -y
        <Ctl-d> (control - d)  This will submit the job.
        # exit

If we could rewrite wakeupat or reboot to take some
extra boot options or alternatively run some Linux loader
(SILO/MILO) from IRIX then 2) should be easy.

[I'm forwarding this very helpful hint from Christian to the list
 not sure if all our audience, especially those outside SGI are aware
 of all these options.]

Now since after setting nvram it'll always boot Linux ;-)
the question is how to toggle two different (Linux/IRIX)
nvram settings in a friendly trivial way...

Looks like a SILO option after the wakup/reboot would be the best.

	Press 1 to boot IRIX [default]
	Press 2 to boot Linux

	I think irix decides where to boot from from these nvram variable...

SystemPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(8)
OSLoadPartition=pci(0)scsi(0)disk(1)rdisk(0)partition(0)
OSLoader=sash
OSLoadFilename=/unix
OSLoadOptions=auto

You could write a script to fudge them with the nvram command then
shutdown and wake up.  Unfortunately I don't have the disk/time to play
with it at the moment

Not necessary.  Use nvram to set SystemPartition (and maybe one or two
other prom variables?) to point at the Linux disk and then just init 6.

Hello guys,

   I have a new question for all of you lucky STREAMS experts.  Ok,
the thing is, I am not familiar with STREAMS at all, so I am not quite
sure at what to do next.

   What is the ioctl (fd, I_STR, XXXX) thing supposed to do with a
STREAM file handle?  I just can't find any documentation on what this
is for. 

   Is this I_STR thingie done by some higher-level routine (I see
there is a getmsg and putmsg routines declared, is this the way those
routines are implemented, or I am missing the point?).

cheers,
Miguel.

Hello guys,

    Ok, now I need some advice here:  I have this piece of code which
is not cooperating very much.  You can help me to figure out what is
going wrong by taking a quick look at the Xsgi source code.

    On the directory programs/Xserver/hw/sgi, you have to grep for
shmiqInit, once you find it, quickly figure what I am doing
wrong.  And if you have a chance to tell me what the thing with XXX
is, I will be even more happy :-)

cheers,
Miguel.

To paraphrase Michael Stipe, "STREAMS, they complicate my life."

I_STR is the catch-all ioctl.  What it means is that some random, device-
specific ioctl is being sent down.  The way that this works is that the app.
fills in a structure, and then magic happens.  The third argument to ioctl()
is a 'strioctl' structure, which is defined in <sys/stropts.h>.

For example, suppose my STREAMS driver supported a "panic the system" ioctl.
Suppose, too, that this ioctl took an argument which was the message to print
out, e.g., "eat me."

The app would have code which did something like:

	#define SYS_PANIC 0xbadd0g
	struct strioctl si;
	char *foo = "eat me";
	int fd, r;

	si.ic_cmd = SYS_PANIC;
	si.ic_dp = foo;
	si.ic_len = strlen(foo);
	si.ic_timout = INFTIM;		/* infinite time out */

	fd = open("/dev/strcrash", O_RDWR);
	r = ioctl(fd, I_STR, (char *)&si);

Meanwhile, in the kernel...

The data area pointed to by si gets converted into a two-part STREAMS message:

The first part is a block containing an 'iocblk' structure, which has the
command and a length, etc...  The continuation pointer (b_cont) of the first
block points to the data portion (i.e. ic_dp), which in this case is the string 
pointed to by 'foo'.  The length of the first block is sizeof(struct iocblk)
and the length of the second block is strlen(foo).  The data is pointed to by
the 'read pointer' (b_rptr) field of the message block structure.  This leads
to code similar to the following:

/* write put procedure for STREAMS crash driver */
stc_wput(queue_t *q, mblk_t *bp)
{
	struct iocblk *ioc;

	/* determine message type */
	switch (bp->b_type) {
	case ...
	case M_IOCTL:			/* it's an ioctl message */
		ioc = (struct iocblk *)bp->b_rptr;
		/* what command */
		switch (ioc->ioc_cmd) {
		case SYS_PANIC:
			ASSERT(bp->b_cont);
			cmn_err(CE_PANIC, bp->b_cont->b_rptr);
		}
		default:
			ioc->ioc_error = ENOTTY;
			freemsg(bp->b_cont);	/* safe to call with NULL*/
			bp->b_cont = 0;
			qreply(q, bp);
	}
	...
}

So, basically, without cracking the M_IOCTL message, you can't figure out what
to do with an I_STR; it's completely driver-specific.  (streamio(7) gives some
info; the USL manual called "Programmer's Guide: STREAMS" has way more than you
want to know).  STREAMS sucks.  Trust me; I did STREAMS TCP/IP for 8 years.

Actually, we frequently have two versions of IRIX that we need to
boot each from a different disk drive.  We have a shell script which
root can run which sets up nvram so that the next time we reboot, it
will come up in the other OS.  Here's the script below:


#!/bin/sh
#
# Usage: switch_os 6.2 switches to 6.2
#        switch_os 6.5 switches to 6.5

if [ $# -lt 1 ] ; then
  echo "Usage: switch_os <6.2|6.5>"
  exit
fi
if [ $1 != "6.2" -a $1 != "6.5" ] ; then
  echo "Usage: switch_os <6.2|6.5>"
  exit
fi
if [ $1 = "6.2" ] ; then
  sys_part="scsi(0)disk(1)rdisk(0)partition(8)"
  os_load="scsi(0)disk(1)rdisk(0)partition(0)"
else
  sys_part="scsi(0)disk(3)rdisk(0)partition(8)"
  os_load="scsi(0)disk(3)rdisk(0)partition(0)"
fi
echo "rebooting venus to use $1 in 5 seconds..."
sleep 5
/sbin/nvram SystemPartition $sys_part
/sbin/nvram OSLoadPartition $os_load
/etc/reboot

Hello guys,

   Ok, I got my copy of the SGI documentation, and here I come with
lots of questions, so take a deep breath:

* Extra documentation
  
	It seems to me that some information on how the Newport works
	is decribed in a manual called 'Indy Graphics', Indy (TM)
	Technical Report, Ver 1.0, 1993.  

	I would love to get a copy of this document if at all
	possible. 

	The 'Display Control Bus Specification' would also be handy.

	The VC2 documentation suggests the later may be available on:
	nexus:/d/newport/asics

* Colors and the newport.

  ** Using 24-bit mode

	For some reason, I am not getting the colors I want on the
	screen.  

	I have tried to use the RGBA (32 bit) mode instead of loading
	the palette and using the color-indexed colors for drawing
	simple things on the screen without much success.

	Here is what I am doing:
		Set RGMMODE to 1 in the DRAWMODE1 register (this is
		supposed to use the colors loaded in COLORI).

		Set the PLANES to R/W RGBA planes
		Set the DRAWDEPTH to 24 bits.

	It still seems to be using the color pallette that IRIX loaded
	for me.

  ** Slope Red/Green/Blue.

	I could not find any reference to the use of these registers.
	Nor what are they supposed to do in the documentation.  

  ** PUP

	What in the world is a PUP?  It is some kind of plane 
* Clipping and Masking

	Could someone transcribe me the last paragraph from page 26
	of the "Preliminary REX3 sepecification".  The copy I got is
	offseted in this region, and thus did not make into my copy.

* Context switching the graphics context.

	Is there any way to stop the currently executing REX3 command
	so that I can save the graphics context.  

	Or should I just assume that saving the context and letting
	the REX3 finish the command even if we jump and do some other
	stuff that restoring the context will do the right thing?

Ok, I am now going to keep playing with the newport now :-)

Cheers,
Miguel.

Hi all,

after having found a couple of bugs in binutils 2.7 during the last
time I decided it'd about time to go for 2.8 instead of putting more
time into 2.7.  Out of the frying pan into the fire ...

 - binutils 2.8.0.13 still need the special patches to gas/config/tc-mips.c
   to be applied.  Otherwise they will reject the %HI, %hi and %lo
   operators.
 - since some pre-2.8 version binutils do optimize the case of the -N.
   This helps to reduce the output filesize but somehow ld layouts
   the segments wrong which results in a unuseable kernel.  Removing
   -N from the LDFLAGS in arch/mips/Makefile is a workaround.
 - The %gp_rel() operator is not implemented in GAS.  This means that
   we cannot assemble PIC code with GAS that is produced by current
   snapshots.
 - GAS still doesn't deal with _huge_ loops.  The only program I know
   of which is affected is lmbench, but that alone is reason enough
   to fix it.

It is not a bug, just that we have the local label semantics specified
for linux-mips differently in gcc and gas.  I fixed this ages ago and

It has nothing to do with local label semantics of GCC; I can easily trigger
the problem in plain assembler using local or nonlocal labels.  Maybe you
were still using a non-PIC lat_ctx at that time?  The problem only affects 
PIC.  Another explanation would be that the size of the cacheflushing
loop in lmbench was somewhen increased or the GCC variant you used generates
different branches.  The problematic GAS code from:
binutils/gas/config/tc-mips.c:

[...]
  3439      case M_BGTL_I:
  3440        likely = 1;
  3441      case M_BGT_I:
[...]
  3470        if (imm_expr.X_op != O_constant)
  3471          as_bad ("Unsupported large constant");

  3537        likely = 1;

Another question for all of you having access to the Xsgi X server
sources.  

I am reading the Virtual DMA specification, and it occurs to me that
this is the only way I can dma from the graphics card and to the
graphics card.  Can someone confirm this?

According to the document I have, to be able to use the VDMA, a least
for R4000 machines, I need support from the kernel, can somebody tell
me what this kernel support looks like?

I can't find anything in the par output I have from running the X
server that looks like VDMA setup.

Have a nice day,
miguel.

Hi All,

I'd like to wellcome (note the spelling) Alan Cox to the linux
mailing list.  To those who don't know Alan, he is almost as
famous as Linus himself in the Linux community :-)

Alan played the leading role in major Linux areas including
The Linux TCP/IP implementation and Linux/SMP as well as being
involved on the Linux International Technical board and helping
Linux happen and succeed.

Alan lives in Wales, The United Kingdom and he is interested
in contributing to the SGI/Linux efffort.  I have put Alan
on the first-comes and qualifies first-serverd waiting list
for hardware.  Right now, Alan in #4 on the list with machine
#1 expected to be shipped this Friday. [our main bottleneck
is lack of dual disk config Indys]

To Alan: the linux@engr.sgi.com list has about 50 subscribers
mostly SGI employees (and a few managers :-) who either like
Linux so much or have some other interest in seeing it running
on SGI hardware.  It also includes all our core developers
which you probably know.

Peace, Ariel

Umm.. not convinced

Anyway my target is basically to make Red Hat occur on an SGI, including
hacking up the RH installer as needed to make it do the right thing.

Anyone know what state the strace stuff in the CVS tree is in?

I'm seeing some weird behaviour with rpm right now (can't find
user/group) and I'd like to see what it's actually doing.

(Also, remind me to work on fdisk when I get back[*] -- I don't like
fx very much.)

The strace is the strace as left by David Miller plus some modifications
by Miguel.  Those add some IRIX bits he needs to reverse engineer what
the X server is doing.

What should LOOP be for the MIPS?
It appears to be the address of the breakpoint handler, but I'm not
sure:
	ptrace(PTRACE_POKETEXT, tcp->pid, (char *) tcp->baddr, LOOP);
	if (errno) {
		perror("setbpt: ptrace(PTRACE_POKETEXT, ...)");
		return -1;

Hi,

I have this 2gig drive sitting on my desk next to my Indy and
doing nothing, so I figured I should try to install sgi-linux,
see if the thing boots, and maybe put togehter a few RPM's
on my own

Unfortunately, at this point in the project, the "How to get
started" part is kind of not written anywhere.

I think if someone could whip together a quick 5 steps to booting an
Indy under Linux and post them on http://www.linux.sgi.com, it'd
be great, especially for people like me who are more the userland type.

I have access to a i586-SCSI Linux system on the same network as
my Indy, so I guess it should make things easier (booting diskless
and/or making an efs filesystem on my SCSI disk on the PC)

Thanks,

	- Mgix (Hi ariel, I'm still around :) )

Mgix,

Glad to see you're still with us in a way!

How to get started:

Yes, this is *the* most important missing piece on www.linux.sgi.com
It should be the first item in the 'HOWTO' section.

I believe we used to have at least two volunteers to write this
a few weeks ago.  I hope they are listening, (no names :-)

If anyone else who has Linux running today would like to write this,
please do.  Make sure you make it short, accurate, reproducible
and as simple as possible.

If you need shell access to administer the linus web site from where
Miguel and I left it, just let me know and I'll give it to you
(you'll need ssh and email me your public key generated
with ssh-keygen)

I had said that I would write this, and I will. It will be written from
the stance of a relative newbie.

As it stands, I have some ideas on how to do this.  What I'm missing is
the actual hardware to do it on.  As I get my system booting, I will
document every step.

The *REAL* fun for me starts when my Indy arrives, hopefully next week.
Thanks, Ariel!

Yes, it will help.

How are things on the native booting front?

I had mailed Erik Troan a couple of days ago w.r.t. getting the RH install
code for Alan and myself, but I haven't heard anything yet.

I can boot bogomips off of local disk, but I'm seeing some wierdness
with users and groups that I can't explain (via NFS and ext2).  I'd
like to get strace working so I can debug it more.

There are also some moderately serious VFS bugs in 2.1.4[35] that are
blocking some stuff right now.  (Can't boot diskless with .45, for
example.)

Further questions:

1. What's a good kernel to use for this, and can someone tell me where I
can find a pre-compiled version of it? I suspect until the problems on
2.1.45 are fixed, newbies should be using something older.

2. Could someone either produce an RPM for an xcompiling gcc host=i386
target=mips-linux, or send me a tarball?  I'd be happy to make it into an
RPM.  Same goes for binutils.

3. Exactly what hardware will this run on?  All I've heard thus far is
work on SGI Indy's.  Has there been any expereience on anything else?  I
know Ralf has run Linux on a lot of different MIPS machines, but for the
sake of SGI Linux I think we should restrict ourselves to SGI only
hardware.

4. Can someone tell me about how to configure an Indy to boot via bootp? I

I think that's it.  Whatever Ariel ships you should work, though.

Configure your bootp server (see the config on neon for details)
correctly, and then:
Hit ESC for maintenance (heh)
5 for boot prompt.

boot -f bootp()blahblah

("blahblah" can be any string...it figures everything out from the
bootp server)

Last time I checked the SRPM files for it where on CD#2. They arent the most
recent but are 4.2. I was thus somewhat suprised you mailed Erik. - BTW the
best person to mail in Red Hat isnt Erik he's generally far far too busy. Try
the support people. I normally ask Clarence Smith if I need to check something.

1. The SGI-linux FAQ

I've compiled version 0.01 of the FAQ, and it is at
http://www.linux.sgi.com/faq.html .

I fully realize that this document is filled with errors, and has some
pretty large holes in it. Rather than mail me saying "Alex, why do you
even bother?", it'd be _very_ helpful if you'd mail me telling me what's
wrong.  No correction is too small.  The goal here is to have an accurate
FAQ.

Understand that I haven't touched SGI hardware in more than a year, which
brings up item #2...

2. My Indy

Yay!  I got a call from David Kascht from SGI minutes before I left work
yesterday.  Apparantly, my Indy is leaving either yesterday or Monday, and
should be in Boston at the latest on Wednesday.  I've decided that the
best thing is to leave it at work until it boots a little better.  That
means it's behind the firewall (which I could, but won't circumvent).

My first project is to properly document the newbie-installation part of
the FAQ.

3. Installation methods

Right now, as documented in the FAQ, the only way to install it I think is
to boot off a remote system using bootp/tftp/nfs-root, setup your disks,
then install RPMs like crazy.

But, what we want to do is move towards a network-less install. I can see
a few ways to do this:

1. Floppy a la PC/Mac 
Can you actually boot an Indy off of a floppy? This would work well
because we could then allow traditional RH FTP and NFS installs.

2. Bootable CDROM
If so, we'd actually need someone to press bootable CD's.

Are there any other ways?  Perhaps creating a boot image from Irix?

I did look in the documentation library, but I came across nothing when
searching for 'boot'.

It compiles and works just fine on IRIX.

Actually -as I mentioned in a previous mail- we should probably add
some of fx's features into fdisk.  

The Red Hat people are working on a newt-bassed fdisk as of now.

The external SGI/Linux site is not yet widely advertised
as we're trying to avoid visibility and a barrage of questions
before we have something stable to show the world and a good HOWTO.

Yet I see pretty impressive interest.
First: we have quite a few ftp connections coming in.
For example in the last two days we got FTP connections
from the following sites:

	UNKNOWN@194.177.3.16
	UNKNOWN@204.155.73.18
	UNKNOWN@Bongo.HGS.SE
	UNKNOWN@SGI.COM
	UNKNOWN@aegir.ifi.uio.no
	UNKNOWN@alex2.med.iacnet.com
	UNKNOWN@alpha.franken.de
	UNKNOWN@click3west.com
	UNKNOWN@dasc12-94.flash.net
	UNKNOWN@dial06.c3.hu
	UNKNOWN@evil.aec.at

	portmaster-ppp-slip-term-30.uni-koblenz.de
	sgi.com
	thoma.uni-koblenz.de
	vulcan.ko.bnc.net

Not to mention web hits.  Since our web server (linus) went on air
We got web hits from the following (note the interest from some
interesting .com sites) some IP addresses are unresolved.

Ah, yes.
I was talking to John Carmack about Quake 2, Linux, GL hardware and
such, and while the Indy's not suitable (only gouraud, and Q2 needs
texture mapping), the O2 would be.  If we can get Linux ported to the
O2 as well, we can very likely get a Quake II port.

This is suspicious.
Should we be controlling access to linus?

Good news from the east coast of the US!

To begin with, I was happy to see two very large boxes getting dropped off
at my cubicle around 2pm this afternoon from SGI.  Had I not been in the
middle of fighting a million other fires this afternoon (multiple
billings, crashed hard disks, etc) I would have opened it sooner.

I know that Ariel has gone through a lot to get the volunteers hardware,
and it says a lot about his hard work and determination that I have an
Indy on my desk right now. SGI Linux would be very difficult to get
running without the input of him and SGI. This _is_ going to work well. 

A few beers are owed to David Kascht for setting up my system properly,
and for getting the machine out the door in Mountainview.  His efforts are
greatly appreciated.

But, at 7:30pm I started unpacking, and by 8:15 I had Irix functional. 
Setting up bootp, tftpd, nfs, etc was easy (note to self:  remember to
restart inetd, remember to restart inetd...), and the whole thing booted
as of about 9:15. The cleaners are still looking at me funny from my loud
cheers.

I'm using Mike's vmlinux version 2.1.43 (11MB!), and the
root-be-0.0.cpio.gz (thanks, Ralf!) root file system.

I'm now sorting out why I can't write to the fs, I think it's because I
had forgotten to modify it's /etc/mtab or such.  No problem, I expect.

So, all I need is fdisk, and we're really rocking...

I've been documenting more specifically, and I will be creating the HOWTO
installation parts tomorrow night.

The plan for my machine (Red) is to host it here at work (as
alex3.med.iacnet.com) behind a firewall until SGI Linux is a bit further
ahead, or until I get an ISDN line (which I will for certain, once I
move).  Red is an Indy with 2 1GB drives, 64MB and ISDN. 

Again, huge thanks to SGI.  I promise to contribute in order to make it
worth their while.

Hi all,

over the time I received several requests of Linux for m68k based SGI
machines.  First of all, did SGI build m68k based machines at all?
If so these machines must be from latest the mid-eighties, probably
earlier?

Ralf,

 those were the first SGI products. The IRIS-1x00, -2x00 and
-3x00 series.

 CPU board based on the 68020. No 68881 FPU, but you could
get a FPU accellerator board based on multiple Weitek chips.
Up to 8 MB (or was it 16 MB, maybe only 4), IRIS-GL based GFX,
MEX window manager. 

 Bus system was Multibus. Disks ESDI, SMD and IPI. Don't
know what the SCSI story was. 

 Build from 83/84 until probably 88. Not a bad system for
that time.

Martin

Sounds as if this beast might be similar to the Weitek based FPA available
for the 68k based Suns.

SCSI to ESDI converter cards were popular at that time ...

I wonder if there is still documentation for these beasts around such
that some dino freak can hack Linux for them?

Yeh, I remember working on the SGI 3130/3120 in 1987/88 . they were
equipped with 68020s

and the ido was included, the os fit on a 60MB QIC tape ...

Hi,

Mark Salter just joined the list.  I hope that having Linux
run on an Indy will soon be very common.  At this point it is
rare enough to be worth posting.

What is nice about this case is that Mark just grabbed whatever
we have on the ftp site currently (which is not yet ready) and
without being involved before, managed to get it to run in short order.

Whoever can fix this: Please note the hiccups and problems in
the process.  Maybe we should just update the precompiled binaries
we give to people :-)

[ pointers deleted ]

Thanks for the pointers, guys. I had relatively little trouble booting
linux on my Indy. I put the "root-be-0.00.cpio.gz" filesystem on my
PPro linux machine and built the kernel from the sources there. The
only problems were:

  * The ".previous" bug in the crossdev binutils binary. This problem got
    some mention in the mailing list, but no resolution was mentioned. I
    got the sources and a patch from ftp.linux.sgi.com, rebuilt binutils
    and that fixed that.

  * I wasn't sure how (or if it is even possible) to get  "root=" options
    to the kernel from the Indy ARC PROM, so I changed NFS_ROOT in 
    include/linux/nfs_fs.h to point to the right place where I placed the
    root filesystem.

So, you can now add me to the list of folks with Indys running linux. I
guess I'll start working on fixing up a second disk so I don't have to
boot off the network...

Linux 68K current has an absolute need for an FPU. Thats one of the big
macintrash problems we are facing as the 68LC040 not only has no FPU but
for many motorola broke the exception handling so you can't even emulate it

Has anyone considered perhaps partnering with either Metrolink
or Xi Graphics (makers of Accelerated-X) and having _them_ be
the providers of the X server for SGI?

It would seem to provide some benefits...

A.  Allows us to keep gfx security.  Neither Metrolink nor
    Xi Graphics releases the source code to their servers,
    and we should be able to get them into some form of a
    confidentiality agreement.

B.  Gives us a venue by which SGI can provide optimized
    versions of OpenGL for Linux/Intel.  This is what we
    could bring to the table.

C.  Lends additional credibility to the Linux/SGI port.

Just an idea.

Okay, I spent some time on my Indy today, and ran into some things:

- somehow, booting with:
boot -f boopt()bootserver:vmlinux nfsaddrs:my.ip.add.ress:bo.ot.ip.addr
doesn't work.  It gives me the error ": can't open".  Odd.

But:
boot -f boopt()bootserver:vmlinux
does work.

- My root partition isn't being mounted read/write.  I can't figure it
out.  /proc/mounts does indicate that it's rw, and I'm sure the NFS export
is setup correctly.

- I have two disks on the system, sda has Irix on it, and sdb is empty.  I
didn't have fdisk compiled (alhtough I tried), but mke2fs /dev/sdb worked.
It mounted, but... I got a tonne of ext2 errors when rebooting and
remounting.  Irix tells me the disk is good.

- While doing a lot of NFS stuff, I got a the following panic:

Got a bus error IRQ, shouldn't happen yet
...
Cause: 00004000
Spinning

and then the whole thing locks.  I'm using Mike Shaver's 2.1.43.  Should
anyone have a brand new 2.1.47, I'd love to try it.

(actually, I should probably sort out how to cross compile my own
kernels... I'd be doing a good thing to package the cross compile
utilities that Ralf's made into an RPM... never mind the .src.rpm for now)

- Is there anyway to get rid of that jazzy sound startup thing?  Sure, it
puts all the Mac's in my office to shame, but after about the twentieth
time it's a little bothering...

- Binaries I'm looking for:  fdisk, ps, network tools... 

Anyway, things are looking better and better...

These two are probably good reasons for having a valued added option.

Hi all,

I've copied my home CVS repository of modutils to Linus.  There are still two
one line fixes to the kernel required to make modules work.  I'll check them
in asap.  Many modules are working reliable while other don't work at all.
I suppose there is still some bug in the relocation code.  Try 'en and check
if they work for you.  When modutils are finally debugged I'll release normal
tar.gz source packages and binaries on the usual FTP sites.

Another note about modules affects the performance.  Modules are allocated in
kernel virtual memory which starts from 0xc0000000 upward.  This exceeds the
range of the R_MIPS_16 relocation for j and jal instructions.  Therefore
modules have to be compiled using the option -mlong-jumps which replaces j
and jal instructions by la jr/jalr sequences.  These take twelve instead
for four bytes and are a bit slower.  There are more efficient way to solve
this problem but these are also more complex.

Simple rules to optimize module code when using -mlong-jump:

  - Try to call as view external functions as possible.  Only calls
    to external functins are affected by -mlong-jumps.
  - Taking the address of a function and calling it via a function
    pointer is advantageous for repeated calls.

This is a problematic specific to MIPS.  The other considerations that
apply to modules on Intel machines apply unchanged to MIPS.

Probably not worth to write that much about ...

No need for that.  I got the time to read all of the documentation on
the newport graphics.  I am da-newport-man now :-).  There is only
*one* thing I have not figured out and which is rather important:

   How can I DMA from the video card to the host memory?

I know I can set the bit that does the DMA, but I have not found how
to setup the DMA transfer to the host memory, so if a SGI graphics
hacker is reading this, I would appreciate a little hint with this. 

We will have a kick-ass X server once I start coding it (I am just
finishing the shared memory input queue driver now which is making me
suffer a bit).  

When I was reading the X11R6 porting guide there were a lot of hooks
that did not make sense.  Then I read the Mark Kilgard's paper on
direct-rendering and got the newport specs, now everything makes
sense.  I am possitively convinced that all the X speed improvements
in the IRIX server are cleanly separated and do not require changes to
the main X sample server from MIT.

So, we can get an X server pretty easily that will match the power in
Xsgi (including direct rendering, I have most of this code written,
just the actual context-switch for the rex3 is missing, will get to
rex3 context switch once I get shmiq finished :-)

Well, the optimizations in SGI's OpenGL require some hardware support:
starting with the direct graphics kernel support, continuing with the
kernel rendering resource manager and then having hardware
acceleration in their video cards and all kind of graphic tricks to
improve performance.

I strongly  recomend reading Mark Kilgard's papers on how they use
the hardware features of the SGI machines to make graphics scream. 

> C.  Lends additional credibility to the Linux/SGI port.

Commercial applications for Linux/SGI will appear at some point, but
rememeber, the ideal world is made up of machines running free
systems.

Miguel

I cvs'd out the kernel this evening, and I tried compiling it.

The compiling tools I'm using are the same ones in the crossdev directory
on linus.linux.sgi.com (and I've converted _those_ to RPM's, for your
installation convenience).

I got the following problems with compiling it:

- in scripts/mkdep.c, in the mmap() function, references MAP_AUTOGROW,
which is unknown.  I just removed it out for my compile.

- in Ariel's instructiosn on how to cross compile a kernel, it says to use 
make CROSS_COMPILE=mips-linux CONFIG_SHELL=/usr/freeware/bin/bash

But, the compile then can't find mips-linuxgcc .  Apparantly, using:
make CROSS_COMPILE=mips-linux- CONFIG_SHELL=/usr/freeware/bin/bash
                            ^^^
works.

(I'd like to absorb this in to the HOWTO, incidentally).

- I get the following compile error:

Ok.  This is my fault, do not compile this module and you should be
fine.  I will try to commit all of my changes tomorrow (with my shmiq

I waited carefully until I was sure that everybody would be asleep, and
rearranged the FTP server.  This may not be a popular decision with some
of you, but I think this structure makes a lot more sense.

The first major change is that I've configured wu-ftpd instead of the
prepackaged ftpd that comes with Irix.

The next change is that I've moved everything to /src/ftp, so that people
aren't puzzled why we're distributing our web logs via FTP.

Also, I've shuffled some of the stuff under the former /pub/linux down
one, and put some source code (such as ktrace) where it belongs.

I've also uploaded my .rpm versions of Ralf's crossdev tools for i486
hosts.  If I had sources I could compile for binutils and gcc, I'd
generate ones for sparc-sun-linux hosted as well.

Anyway, if you don't like the FTP server structure, feel free to complain
to me.

In other news...

- the HOWTO will be seperated from the FAQ tomorrow, bringing both
  versions to 0.03. Plenty of technical details have been added

- I'm working on creating a smaller root.tar.gz package.  Having ps
  and fdisk would be very cool...

Hi all,

I've created a new group "ftpadmin" on Linus.  All files in the pub tree
on the web server now have this groups, the directories are SETGID.
For now all members of the vip group are also ftpadmin members.

Hi,

I tracked the modules bug down.  Turned out that it was an I/D cache
coherency problem; the modutils work fine as they are in the CVS on
Linus.  Right now I really wonder why modules work at all on any
architecture with split I/D caches.

I've built a Indy kernel with 40 modules configured.  Of these 35
seem to be working.  Not that I have taken myself the time to create
the test setups for testing them all ...  Those that don't work on a
Indy are psaux, sgiwd33, ipv6, msdos and binfmt_java.

I'd also use this occasion to introduce Thomas Bogendoerfer on this
list.  Thomas is currently as far as time permits _the_ Olivetti M700
hacker.  Means that he will also get live back into your Magnums :-)

  Ralf

   Right now I really wonder why modules work at all on any
   architecture with split I/D caches.

On most sparc32's with split I/D, the Icache fully snoops the L2 and
even the store buffer.  On sparc64, I flush the icache when a module
mapping is made...

Hello guys,

   I am trying to figure out how the /dev/usema and /dev/usemaclone
devices work on IRIX.  These devices are used by the IRIX Xsgi server,
so, well, we need to support them.  

   I have read the manual page for the devices, but they suggest that
people should not be using this device directly, so it does not go
into any detail about the inner working of it.

   So, I would appreciate information on what this device is supposed
to do and how the libc uses this to provide the spinlocks and
semaphores.  Should be pretty easy to figure out how part of the
interface by looking at the libc implementation for the usinit,
usnewlock and usnewsema functions.

Cheers,

Hi all,

what do you think, should we open a new mailing list where everybody
is allowed to subscribe.  Only the CVS commits and other important
announcements are being posted?  This would help making the development
more transparent by showing interested non-developers what's going on.

Ralf,

I believe we already have one, it was created by me when
David Miller was working here in the summer of 96:

	To: majordomo@engr.sgi.com
	subscribe linux-progress your@preferred.email.address

So just add linux-progress@engr.sgi.com to the CVS commit alias

[This should work for all the SGI internal interested parties
 not sure about external people...]

Just a quick note. The new internet gateway distribution (now available
on dist.engr I think) will include GUI majordomo config.

It can also be done from the shell with "nvram volume 10"
or a similar low value (man nvram).

Are you remounting root after startup and do you have our export set not
to map root to nobody ?

(try mount -o remount,rw -n /)

Subject: Linux/SGI: SHMIQ Cache aliasing problems.
Sender: owner-linux@cthulhu.engr.sgi.com
Precedence: bulk
Content-Length: 1150
Lines: 28


Hello guys,

   I am running into a strange problem with the SHMIQ driver.  I am
allocating a set of pages in the kernel space with vmalloc and then
mapping those pages into the user address space by loading the page
tables for the process with pointers to this region.

   This is needed, since the kernel should be able to put new values
into the shmiq and the userland process can just be busy-waiting for
changes to the head/tail pointers in the SHMIQ.

   Now, I marked the pages as being non-cachable for both the kernel
and the userland, but still, some changes made by the kernel to the
shared region are not picked up by the userland program.

   Note that the userland program always detects when the kernel has
moved the tail of the shmiq, but when actually accessing the event,
sometimes I get zeros on an event that should have other values).

   According to a book I got here, the r4000 uses a direct mapped
virtual cache and I was concerned that the aliasing problems may come
up in this case, so the question is: do I have to flush the caches
even if my pages have the non-cacheable bits turned on for both sides?

Cheers,
Miguel.
