So the caller _bfd_mips_elf_relocate_section does not behave appropriately
when mips_elf_calculate_relocation returns bfd_reloc_undefined.  Search
for bfd_reloc_undefined in mips_elf_calculate_relocation; it's being
returned before an actual value gets assigned to *require_jalxp.

I'll send you a non-giant tarball of 73kb which will demonstrate the
problem.  Just run the Makefile in the archive.  The linker has been
configured for the target mips-linux which is a standard MIPS/ELF target.

Ok, I'm looking into things in parallel if I find the time.  I'll also
try to rebuild GNU libc for MIPS.  That has historically proven to be
a bone breaker for ld.  The last time I tried a few weeks ago I got
~500 assertion messages from ld just alone for the libc final link ...
Will let you know how things go.

Hi,

the cvs version of gas has a tiny typo which prevents it from swapping
an instruction preceeding a jump or branch in most cases.  The fix is
trivial and appended below.

      Suppose you define a range of request_irq() index values which
correspond to EISA interrupts.  The generic EISA interrupt would always
be enabled, and the selective masking would apply to various bits in the
EISA interrupt controller, in much the way that the cascading interrupts
in INT2 and INT3 are handled.

The solution which we're using for other systems is to number the
interrupts such that 0 ... 15 are the (E)ISA interrupts; all other
system specific interrupts use higher numbers.  In such a scenario
request_irq() will essentially just be a demultiplexer which for
(E)ISA interrupt numbers calls request_isa_irq() etc.  You really
should try to leave the interrupt numbers unchanged as they are;
basically every (E)ISA interrupt driver has it's numbers hardwired.

No, but I'd prefer symbolic names like SGINT_WD93_1 over SGINT_LOCAL0 + 1.

MIPS users should continue to use the latest 2.8.1-based releases
available from ftp.linux.sgi.com.  All newer linker have heavy bugs
which will result in linker crashes, bad kernels and more.  I especially
have to warn about the binutils from Cygnus' anonymous CVS.  At this
time the MIPS support in that binutils versions is undergoing heavy
rewrite in order to support the N32 ABI and as a temporary side effect
they are therefore currently completly unusable for Linux/MIPS.

       I see that some drivers use NR_IRQS to form an IRQ_ports[] array,
to map from IRQ to board object, as in serial.c, whereas others, such as
riscom8.c, wire in 16 as the limit.   Still, you could make
probe_irq_on() and probe_irq_off() actually work for an Indy and Indigo2,
and simply declare broken any drives which do not use NR_IRQS and probe
using the probe_irq_* routines.  The biggest problem with that approach
is that NR_IRQS is 64 on mips, which means that probe_irq_on() and probe_irq_off()
would need a different interface (long long instead of int, to allow 64-bit
IRQ bit maps on 32-bit kernel).  

      Changing the MIPS symbolic IRQ mapping to put EISA in the bottom
16 slots is probably the course of least resistance.

     That suggests that we need to renumber the levels in sgiint23.h,
moving all of them up by 16 to make room for the EISA interrupts, and
then increasing NR_IRQ to at least 68 from 64 to account for the extra
levels.

Indeed, but I don't see a problem with that.

probe_irq_{on,off} are being used for interrupt probing only and that's
an art only practiced for ISA.  So we don't even want to support these
functions for interupts >= 16, that is non (E)ISA interrupts.

While working in EISA support for the Indigo2 I have run across some
interesting design decisions and I would like to get some feedback.

First is interupt handling.  On the Indigo2 all the EISA interupts and
mapped down to a single INT2 interrupt.  In other words, an [E]ISA card
generates an interrupt, which in turn, generates an INT2 interrupt, which
generates a CPU interrupt.  This causes a problem because current device
drivers do a "request_irq" call to allocate an interrupt, on the Indy and
Indigo2, this procedure allocates an INT2/3 irq.  ASFAIK, this means that
to be supported on the Indigo2, the device driver needs to call something
else like "request_isa_irq", so that it can be allocated properly.  I see
two ways of implementing this.  The first is easier to implement, but
looks slightly grotesque and would involve lines like:

#ifndef CONFIG_SGI_EISA
request_irq(....);
#else
request_isa_irq(....);
#endif

the other would be to create a "request_isa_irq" procedure that defaults
to "request_irq" in most architectures.

Does anyone have any comments or suggestions on this?



The second is a request for comments on the advantages/disadvantages of
implementing EISA support as a loadable module?  There is nothing in the
running system that actually requires it to be available, and I think it
would be neat to have bus support as a module.

I hadn't even thought about doing it that way, but after looking at the
existing interupt code, it shouldn't be much of a problem. My biggest
concern is maintaining compatability with the existing drivers. From what
I can tell, they all grab IRQs in the range of 1-15 (the available range
for EISA on x86 machines).  So the best course of action is to shift the
virtual IRQ numbers up to start at 16, and put the EISA irqs on the 0-15
range.  Are there any major things I should consider before doing this?
Are there any arguments against this?

That's basically what William Earl suggested.  I am going to change the
SGINT_XXX defines in sgint23.h to leave space for the (E)ISA interrupts
and get change any absolute references (like in the SCSI driver) to things
like "SGINT_LOCAL0 + 1".   Is there anything else I should allocate some
space for?

My binutils work is part of Linux/MIPS64, at first for the Indy, then
for the Origin 200 and other 64-bit MIPS based systems.  It'll be
quite a while until we'll also have a 64-bit userland, but that's also
one of the aims.

Mark, for now I'm just posting this in the hope it may ring a bell.
It seems like HI16 / LO16 relocation pairs are not handled correctly
This may result in ``la $reg, symbol'' ending up after the final link
as ``la $reg, symbol + 0x10000''.

I'll try to come up with a resonably small example tomorrow; right now
I've just discovered this problem and can only show the problem in
the diffs of disassembler listings between the two builds of a Linux
kernel with binutils 2.8.1 and cvs-binutils.

I think the core differences are probably that I tried to compile non-pic
code and code which tries to use GNU extensions.  I intend to recompile
the entire Linux distribution with this new linker which probably will
trigger a few more bugs according to my past experience.  Finally the
Linux/MIPS64 kernel will exercise non-PIC 64-bit code - hopefully
without triggering any new bugs ...

Here's a question from way out left field, but maybe I'll get lucky today:

Does anyone know of a Linux port to the NEC DDB-VRC4374 embedded evaluation
board? The board is an evaluation platform for the NEC VR4300 MIPS CPU with the
NEC Vrc4373 support chip, which would make a great platform for embedded Linux
work with high mips/$ and the flexibility of PCI.

Failing that, if it hasn't been done, can anyone offer a guess as to how hard a
port might be?

Regards,
Graham

Try avoiding crossc-compilation if possible ...  Crosscompiler & linker
binaries are available on ftp.linux.sgi.com just like all the native
binaries & source you might need.

I've connected my Indy floptical drive under Linux for the first time, and
the kernel accurately detects and sizes it (when a diskette is in).  Since
I've never had the opportunity to actually purchase a 21 M floptical
diskette, the default media are IBM format dikettes.  When I try to add
msdos or vfat filesystem support to the kernel (latest CVS) I get the
following failure:

Linus broke all filesystems some time ago, this is not MIPS specific.

Try the 2.2 kernel instead, I think they should be ok.

Just to make your waking sweeter, latest cvs-binutils plus the R_MIPS_26
patch from my other email plus your elflink.h patch build a working
Linux kernel!

Here is my first patch for moving around interrupts for future support of
EISA.  I want reassurance that I've done all of this step before I send
out the code that actually moves them around.  I have defined everything
in the form of "SGI_XXXX_IRQ" to match the definition for the keyboard irq
that used to be in sgihpc.h.  These patches go against the linux_2_2

I am getting consistent signal 11 errors while trying to compile the 2.3
tree from the CVS archives with gcc-2.7.2.  They always occur on the same
files and in both my normal cross-compile enviroment and in the native
Linux-MIPS enviroment.  egcs seems to work fine in the native enviroment.
Do I just need to upgrade my cross-compiler setup?  Is there a tarball I
can install instead of fussing with the RPMs on the web site?

Thanks,

Andrew

cc1 of gcc 2.7.x is known to die on a number of C constructs like

bfd_link_section_stabs (void)
{
	unsigned long long i, count;

	for (i = 0; i < count; i++);
}

when optimizing.  This a compiler that was written even before the
invention of slived bread, so I don't care :-)

There are binary crosscompiler rpms and native compilers for a number of
hosts online.  If you don't like using rpm, then you can still use rpm2cpio
and cpio to just extract the files from an rpm archive for your favourite
architecture.  Right now we've got binaries for Linux/{Alpha,sparc,i386,ppc}
online and I'll upload IRIX binaries rsn.  I just want to lobotomize
binutils before that :-)

Over the last couple of days I've been working on bashing all bugs out of
current CVS binutils from Cygnus.  The result is that as of yesterday
my working version is probably better then ever.

The downside: one of the bugs, misstreating R_MIPS_32 relocations was
present in all previous versions of binutils.  Here the details for those
who care:

Assume two source file, the first one:

	.data
	.globl	var
var:	.word	external_reference

Using binutils 2.8.1 the assembler outputs the following relocation record:

RELOCATION RECORDS FOR [.data]:
OFFSET           TYPE              VALUE 
0000000000000000 R_MIPS_32         external_reference

That's the correct behaviour.  So, now make that a reference to a
global variable defined in the same source:

	.data
	.globl	var
var:	.word	other

	.globl	other
other:	.word	42

This time the assembler will emit:

RELOCATION RECORDS FOR [.data]:
OFFSET           TYPE              VALUE 
0000000000000000 R_MIPS_32         .data

This relocation should be against other.  Why is this a problem?  Assume
both files would be referencing the same global variable.  They get
linked together as part of a final program / library.  Then at runtime
the linker will resolve the one reference to the local instance of the
variable and possibly to another instance for the other reference.

This problem may sound rather theoretical.  Well, it isn't.  Lots of
software out there does nasties like ``int errno = 0;''.  So once we're
finished with fixing binutils every single binary should be recompiled
and eventually exchanged in order to finally get rid of it's effect.
It's probably only causing actual problems in a very small number of
binaries but I though I should mention it.

This patch should fix the error you are seing below, but probably won't do
much for your original complaint.

I am looking at whether I should use the interrupt handling in
arch/mips/kernel/irq.c for the i8259 or the stuff in
arch/mips/sgi/kernel/indy_int.c for local interrupts as a basis in doing
the EISA interrupt handling.

Thanks,

Andrew

    I have a Tandem model number CMN B006S that I'm trying to get Hard
Hat up and running on.  This is a machine build for Tandem by SGI and,
based on the descriptions I have read, I believe it is a close cousin to
the Challenge S.

    For instance an hinv returns:
Syestem: IP22

When I try to boot off of the 2.1.100 kernel distributed with Hard Hat I
get this:

Spinning...

     Now I have spent a some time browsing the archives and I know this
was a common problem some time ago on certain models of Indys.

    I can get the system to boot by replacing the Hard Hat vmlinux image
with the vmlinux-indy-initrd-990313.gz image found in
ftp.linux.sgi.com/pub/linux/mips/test.  But that leaves me with a
crippled RAM disk image and a root prompt.  I can NFS mount my Hard Hat
file system, but that doesn't help me run the installation.

    My question is: Can I get a precompiled vmlinux replacement for the
Hard Hat distribution which will allow me to continue with the
installation?   Or, since Tandem is not officially supported,  do I
spend the next couple of months hand assembling a root partition on the
machine from the bits I currently have working via NFS?

    Any advice anyone could give me would be greatly appreciated.

    Thanks.

Another binutils status report - as of now I still have two open bugs:

 - ld doesn't fill the .got entries for non-dynamic binaries.
 - binutils-current are so extremly wastefull with .got space that we run
   out of got space for building relativly simple programs like vim.
   There is a workaround for this problem which is using compiling things
   with the -Wa,-xgot option.  Not really a good idea because it requires
   recompilation of several packages with that option but at least it
   works ...

Btw, binutils 2.8.1 died the SIGSEGV death when trying to link vim ...

Add another bug - binutils 2.8.1 had a bug which was compensated by
another bug in ld.so.  So if we fix either one we break binary
compatibility.

Grrr,

I now have implemented a workaround for this problem.  The fix consists of
two parts, a patch to binutils which will tag all newly generated binaries
and patch to libc which modifies the dynamic linker to do the right thing
for the old and the new binary flavour.

There are still victims of the problem, all binaries which have been linked
statically against libdl, most important rpm.  Since they incorporate the
old broken dynamic linker which doesn't know how to handle correct ELF
binaries they have to be rebuilt.

For those installing their binaries the recommend upgrade procedure is:

 - upgrade rpm
 - upgrade glibc
 - upgrade binutils, if installed
 - install/upgrade any other binaries you wish to install/upgrade.

The order is important!

Note that I haven't produced any new binary packages yet since the above
mentioned two problems with static linked binaries and the got bloatage
still aren't fixed so this is just to keep you uptodate.

Could you send me a the full hinv output, just to verify that this
system is really an IP22 with no Tandem specific specials?

Further, what is the product name under which this Tandem was marketed?
Is it CMN B006S?  I'd like to document the fact that this machine is
(un?)supported in the Linux/MIPS docs.

Yep, but it's fixed.

That particular kernel was on there for testing the initrd functionality,
so you're experiencing exactly what is supposed to happen.

There are several kernels in exactly the directory you got the initrd
image from.

I have never heared about these Tandem machine but I assume that it it
identical to the Indy rsp. Challenge S.

Hi,

Try these sites: http://www.sgi.com/processors/
                 http://www.mips.com/publications/index.html

Also some of the chip licensee's like www.qedinc.com and www.idt.com
have information.  Does this help?

Binutils now have more or less reached a state where we can use them
to sanely build a distribution.  What's still missing is support for
the N32 and 64 ABIs in the assembler such that we also can build a
64-bit userland.  Volunteers?

Does anybody still rely on the linker support for ECOFF binaries?  I'd

    Well the above is all that comes from a straight hinv.  I do get more if
I do an 'hinv -t' or 'hinv -t -p' though.  Half of the 'hinv -t -p' scrolls
off the screen and the information seems to be redundant anyway (4 lines to
describe serial port 1 for instance).

    Here is the output of an 'hinv -t'.

    Now I don't know what it means by keyboard and pointer.  The machine has
no keyboard or mouse port.  It does have two serial ports that look like PS/2
mouse ports though.  I'm running the dumb terminal off one right now.

    I don't know to both questions.  The only identification the outside of
the box is the above model name/number affixed to the bottom panel.  The box
is jet black  and says TANDEM in the lower right corner.  I've opened it up
and it has a copyright 1993 Silicon Graphics on one of the circuit boards,
but the machine is absent of any obvious identification.

    Cool.  Any idea which one I should use?  Or should I try them all until I
find one that works?

    Well I could give you a bastardized history lesson.  Bastardized in the
sense that I think I know the story, but could be wrong since I'm repeating
info that has been passed to me through multiple sources.

    Tandem was a company situated in Texas that was in the business of
selling business servers.  At the time this box was purchased, Tandem was
repackaging SGI hardware and selling them as Tandem servers.  Since then
Tandem has been bought by Compaq, which I believe where more or less bought
Tandem in order to acquire the brand name.  Currently I believe Compaq sells
industrial computers under the Tandem name.  I do not think those machines
have a MIPS chip set though.

    Keep in mind everything or anything I said in the above paragraph may be
wrong. 8-)  I'm just repeating hear say.

    I actually have a second Tandem box which is still a mystery box since it
requires a 220 outlet and the power grid in my apartment needs to be
customized to support it. 8-)  Once I get that monster up and running I'll
have to run an hinv to see what it has for guts.

    Thanks.

    Cory

This looks indeed very much like an Indy, less a Challenge S.  A Challenge S
usually has an additional WD33C95 SCSI controller as well as an extra
Ethernet.  Also, afaik the keyboard controller has been removed from
the Challenge.  So your machine looks like an Indy with the GFX removed.

Too bad.  Guess for now I'll just use that ``CMN B006S'' ...

Sorry, offhand I don't know which one is working.  Most of these

kernels ...

Tandem has a very interesting program of HA machines and software.  They
have more or less the only UNIX systems that guarantee like 99.99999%
availability.

220 everywhere here.  But I fear that I'll soon need a 400V connector
for my next machine ...

You mean Milo ...  Milo needs to be ECOFF but our compiler produces ELF
output.  Furthermore since we need relocatable ECOFF binaries for the
SNI firmware (actually the specs require it, but only on SNI we really
need it) we have to link PIC code to ECOFF.  And that is way too strong
stuff for ld to cope with.  That's why we're using elf2ecoff which is
now included with every Linux kernel.

    Actually it does have the second SCSI, but it is not showing up in the hinv
for some reason.

    I've opened up the box again to have another peak at the boards.  The top
board says this:
Silicon Graphics Inc.  Copyright 1994
SCSI-MEZZ CHALLENGE-S 030-8221-002 REV: D

    This board has the WD33C95 SCSI controller chip on it.  This board has two
wide SCSI ports out the back and an RJ45 which should be an ethernet.  It has the
little network symbol by it.  I initially tried that RJ45 port for bootp, but had
no success.  The main board below it has a female DB15 connector that I connect a
ethernet transceiver to in order to run bootp.

    The bottom board additionally has the two PS/2 like serial ports, one DB25
female (don't know what it is), and a thin SCSI port.

    It has no keyboard or mouse port even though the hinv claims it does.  I
wonder if this machine could be loaded with the incorrect boot prom?

<snip, snip>

    Yeah it looks like Tandem is still around.  And it looks like you can still
buy MIPS based systems from them, although the sticker shock would probably kill
most of us mere mortals.  8-)  I think the claim they make is more spectacular
than the hardware they sell.  They were making this claim back when my Tandem was
made, and as you can see it is basically a Challenge S or Indy.

    Thanks.

     The keyboard and mouse hardware is in the ASIC set, just not attached
to connectors.  This is definitely a Challenge-S.  The mezzanine card (which
plugs into the GIO connectors where the Indy graphics card would be) is probably
not being recognized by the drivers you have configured, both for the WD33C95
SCSI controller and the extra Ethernet controller.  That is, you see the
base SCSI and Ethernet, not the extras on the mezzanine card.

Tandem had 2 computer lines: the fault-tolorant Himalaya line running
their own OS called Non-Stop built with MIPS CPUs, and the Integrity
line which was OEM'ed SGI Challenge servers running IRIX.

Looks like new Himalaya servers are built around Alpha CPUs.

      Tandem had more lines than that.  They sold the S/3, which was
a triple-modular-redundant UNIX box, with MIPS processors and a hardened
version of MIPS RISC/os, mainly sold to telephone companies.  The S/3
was designed and built in Texas.  They also OEMed various SGI servers and
workstations, notably Indy and Challenge/S systems.   The Tandem versions
of the latter were identical to the SGI versions, except that the plastic
covers were black with a Tandem logo.

    So I can confidently say I have a Challenge S with a Tandem cover.  The machine
was running IRIX prior to me acquiring it.

You'll need the system cd's, or at least the first cd, to reset the root
passwd. When the system starts, press escape to go into the maintenance
menu and then choose install system software. (Were not actually going to
install the system software). At the meno choose Administration (opetion
13 I believe) and then type chroot

This will put you at a prompt so you can type passwd and give a new root
passwd. As far as I know this is the only way to change things...

    I've spent most of today installing (through trial and error) Hard
Hat on the the Tandem.  And It looks like I have been successful!

    The installation process certainly wasn't what I would call smooth,
but it was worth it.

    Thanks to everyone who provided me hints on identifying this
machine.  I have never had access to an Indy/Indigo/Challenge S before,
so identifying this machine on my own would have been a total guess
without the resources of this list and its archive.

    Now the fun begins.

    Thanks again.

Has anyone heard anything about the status of SGI Linux on an Indigo2?
I've got this box here with 128mb and Extreme graphics, and am wishing
I could fire up Linux on it....

Hi,

as those who are tracking the CVS archive or the commit mailing list
probably already have seen I've got started to work on a 64-bit kernel.
I'm also using the chance to do a major overhaul of various code which
over the years had turned into a major uglyness.

In particular the machine abstraction layer needs some overhaul.
Basically the attempt of doing generic kernels for MIPS is dead by now.
Given the number of different firmware implementations and memory layouts
makes it impossible to build a single generic kernel image that fits
more than a few machines.  In fact so far the only combo that was working
at all was Magnum 4000 / PICA / RM200C.  So I'm wiping out all that code
which makes things look significantly nicer.

As of now the MIPS64 code is still in it's very early stages; it doesn't
even compile.  However I'd like to invite other people to alreasy start
working on porting the machine specific bits to MIPS64.  I myself will
initially only implement support for the SGI IP22.  When this one is
running flawless I'll go on with IP27 and SMP support.

Even though I've invested a horrible amount of time int tracking down
the bugs in current binutils they're still in a rather sad state for
64-bit stuff.  Volunteers _urgently_ wanted.  Note that these problems
will also affect other operating system, so it doesn't necessarily have
to be a Linux volunteer.

Cheers,

  Ralf

Note that it's not compeltly impossible, just unattractive to make a
generic kernel.  So if necessary we can do it.

For many systems we cannot drop all indirections.  For example the Indy
shipped with a large number of CPU options, each of which we have an
optimized routine for.

Well, it did for me with an Indy running 5.3 .

As an aside, Irix as shipped has to be the most simple unix variant to
break that I've ever come across. Why on earth does all that stuff have
to run setuid root? Never thought I'd be advocating a switch to Linux
on security grounds, but there you go!

Pete

I think that may be a bit unfair.  Irix 5.3 is real old (Nov 17, 1994)
and while it had many security issues I think a lot of other vendors
probably did as well in that time frame.  There are a lot of security
patches available for Irix 5.3 and I'm guessing they are probably not
loaded on the machine you are using.  These patches are made available
to everyone regardless of whether you have a support contract or not. 
You can find information at
http://www.sgi.com/Support/security/security.html  If you find something
that is not fixed you can report it at that site as well.  

Cheers, Alistair

Could anybody provide me with infos about the commit mailing list?  I

Well, you won't be able to use your graphics card yet, but you can still
get it up and running.  Set yourself up with a serial console, and follow
the installation instructions on http://www.linux.sgi.com/ and off you go.
You'll probably want to build your own kernel from the CVS arvhive, as it
will have more recent changes.  Support for the (E)ISA bus should be
coming along sometime this week.

What is the status of Linux on a Indigo 1 R4000 ? I just procured a
IRIS Indigo R4000 Entry with a video card upgrade ( elan I think )
50 Megs of RAM but has no OS .. I came across a IRIX 5.3 cd set .. but I'd
rather use linux.  Any help installing linux on this platform or any idea
how I can tweak something to make it work, would be immensely appreciated.

No problem, that's why we have elf2ecoff as part of the kernel sources.
Directly linking elf to ecoff is too strong stuff for ld anyway, at
least for some of the ultra hairy case we have to handle.

Yep, because it's not documented.  The mailing list is a plain
sendmail alias.  But I think you can also subscribe to it by

echo "subscribe linux-progress" | mail majordomo@engr.sgi.com

Hello!

Now I have some fatal error in building cross-compiler for MIPS using egcs-  
1.1.2.

My host linux is the redhat 5.0 running on the i586 machine.
I used egcs-1.1.2 from cygnus ftp and configure instruction is
$ ./configure --prefix=/usr/local/mips --with-newlib --target=mips-linux
$ make ALL_TARGET_MODULES= LANGUAGES=c.

Hi!

I tried to install linux to my sgi indy yesterday, kernel starts up
normally and hangs after "Freeing unused kernel memory 44k freed". Then
i only can reboot the machine. I really don't find the thing causing
that, maybe someone can give me an advise to get linux to work fine.
Hardware:
ip22 175mhz
64/128mb ram (Depends which machine)
2gb hdd (2nd machine 2x1GB).
hinv says that i have a indy 24bit ... does this card is supported? I
think so, because kernel messages are printed on the screen, so entire
linux should do so.
So how can i get linux working?

regards.
Jens Oeser

Here is my initial patch for adding EISA support on the Indigo2.  It has
allowed me to get an ISA Etherlink III running in my Indigo2 with a couple
of changes to the driver.  Several things have yet to be done:  I have not
looked into DMA support;  Interrupts on the EISA bus are not reported via
/proc;  "make config" won't allow you to select any (E)ISA bus network
drivers;  I have not looked at irq probing either.  Also, remember that
many drivers will not work on the Indigo2 because they were written with
only little endian architectures in mind.

Things I want some input on:

1)  Should the #ifdefs for making the support optional be put somewhere
      else, it looks clunky in "indy_int.c".  I thought about putting it
      in i8259.h by creating stubs if support is not supposed to compiled
      in.

2)  Where in the /proc/interrupts output should the (E)ISA interrupts go?
      They have a range from 0-15.  They could be interleaved with the
      current set with an [EISA] tag.  Any opinions?


-Andrew

P.S.  This goes against the 2.2 branch of the CVS tree.

    I had the same problem when I installed Linux on my Tandem, an Indy
like machine.

    You might want to try one of the kernels from
ftp.linux.sgi.com/pub/linux/mips/test.  I had good luck with
vmlinux-indy-2.2.1-990329 which apparently fixes this problem for some of
the R4400 CPU based systems.  Just replace vmlinux in the NFS partition or
boop directory, depending on how you are doing the install, with this new
vmlinux-whatever.

    Good luck.

Hi!

I got it working now, with vmlinux-r4400 ... other kernels are booting
but kflushd messes up my screen. The kflush always want to tell me when
he flushes something ... i really would have the sound kernel, but i
cannot use it because of kflushd trouble, anyone expierences with that?
I modified syslog.conf, but it doesn't work. Seems to be direct from the
kernel. I try i selfcompiled kernel today, maybe this helps me.
Another problem, If i try to add a swap partition, it only get's a size
of 20mb with fx, if i resize, the partition is not longer recognized as
swap, and the hardhat install program does not let me make it to a swap.
Is there i way to get it managed, without using linux tools for that?

regards.
Jens Oeser.

luck..

binutils(2.8.1 + recommended patch) builds and installs fine
egcs(1.0.3a + recommended patch) first installation builds and installs

glibc(2.0.6 + addon libs) doesnt come close to building
( [root@sushi build]# CC=mips-linux-gcc BUILD_CC=gcc AR=mips-linux-ar
RANLIB=mips-linux-ranlib
../configure --prefix=/usr --host=mips -linux --enable-add-ons=crypt,linuxth
reads,localedata --enable-profile )

I have tried this setup on a i386 redhat box (6.0) and on sparc running
solaris 7, and taken great care to follow the instructions in the howto.

The patch that is used on glibc-2.0.6 in the Linux/MIPS HOWTO is no where to
be found ? ie glibc-2.0.6-mips.patch

Anyone got a clue what im doing wrong ? (also tried to use the precompiled
packages of binutils/egcs etc, no luck there either)

best regards,
