Hi guys.

You can find my patches against HJ's binutils 2.8.0.2 at 

	ftp://ftp.london.uk.eu.org/pub/arm/binutils-2.8.0.2-970503-diff.gz

Please check them out.  You need to configure as "arm-linuxaout" or some
variant of that.  There is no "arm-linux" configuration in this version;
that is reserved for ELF. 

p.

FYI, HJ is going to merge these after 2.8.0.x is released publicly (should
be today or tomorrow).  I will see if I can get the gcc changes in before
2.8 is frozen, as well.

No.  The latest on this is that Russell has some preliminary patches for
binutils, but there's still a way to go.  He doesn't have any ELF
documentation, which isn't helping.  Also, there is no real standard for
ELF on the ARM - I spoke to the guys at ARM Ltd about this, but although
we decided that it would be good for the Linux people to work with ARM to
implement ELF, nothing much has actually been done.  Other vendors have
done ELF for the ARM in their toolkits and we're waiting to see how they
went about it.

That would be cool, thanks.

I have put my patches for gcc at 

	ftp://kc.london.uk.eu.org/pub/gcc-arm-diffs.gz

They are against ss-970421, but I imagine they will go into any recent
snapshot.  I am about to send these to the gcc maintainers.

Russell, not all of the patches you made are included.  There were some I
wasn't happy with, and some that are in already.  If you think anything
important is missing then say so.

OK.  A few people seem interested.  I have a CD-R machine on my desk now,
and I'm just waiting for the latest Linux stuff to arrive from Russell
(I'm promised it will be here tomorrow, so fingers crossed). 

Anybody who wants a disk, please send 12ukp to

	Phil Blundell
	U2 Burrell's Field
	Trinity College
	Grange Road
	Cambridge
	CB3 9DH

Don't forget to let me have your address to mail the disks.  If all goes
according to plan you should have them by the end of the week.

No.  Just in case anybody is curious as to whether their hardware is
supported, at the moment we seem to have drivers for these network cards:
	
	Ether1
	Ether3
	EtherH
	AMD 79C961A (EBSA on-board Ethernet, I think)

and these SCSI cards:

	Acorn SCSI (AKA30)
	Cumana SCSI 1
	EcoSCSI
	Oak SCSI

If anybody wants to write a driver for another card then please do.  It's
not very difficult.

That would be cool.  I'll see if I can make it available for ftp here as
well, but I'm not sure I have enough disk space to keep it indefinitely.

I dont have the disk space, I do have a spare single speed SCSI CD ROM

The answer _ought_ to be "yes" to both of these.  I don't have any
personal experience though - can anybody confirm that?

In any case it ought to be possible to make it work without too much
hassle.  The code is certainly there for ATAPI, since it's
architecture-independent.

Hi Everyone,
  Having suitably grep'd our xferlog I can tell there are those of you

Hi all.

The distribution that Phillip Blundel has recently been talking about
is an almost direct copy of what I, myself, am going to send him.  This
will be a totally untested distribution, quite possibly capable of
totally screwing your system.

For instance, the boot loader and so forth need to be tested on a known
problematic setup.  This known-problematic setup is basically a 1GB hard
drive from Acorn.  However, I do not currently have this drive.  It was
supposed to be with myself in January, but unfortunately, the Post Office
do not appear to be capable of delivering such a package - indeed it was
found last week up in Edinbourgh!

There does exist a known problem in the boot loader which means that it
*will not work* on large disks (disks > 512MB).  I believe that I have
fixed the problem, but am not positive, and indeed it may cause more
harm than good.

However, I have now received confirmation that it will be sent to me
to arrive later this week.  Once it has arrived, I can check out:

a) The RiscOS tools are capable of performing their function correctly.
b) The distribution has a hope of even installing.
c) The distribution has a hope of running.

Currently, it would be extremely foolish of me to do anything except
with hold ARM Linux until such a time that I can be reasonably happy that
there aren't going to be 100000000 people mailing me complaining about
the fact that this CD that they have paid for is only useful as a coffie
cup mat.

The distribution is currently moving as fast as it can at, since I have a
*full time*, no not 9-5, more 7.30am - 9pm job, 6/7 days a week, and that
simply does not leave time for ARM Linux to progress fast.  Unfortunately,
this style of working does appear to be all to common in Britian, especially
when impossible deadlines are imposed on saftely critial systems (eg. JLE PA
systems).

Dave Gilbert has the same sort of problem.  He maintains the Linux kernel
for the older machines, and quite honestly, it is only suitable for use
in a root NFS'd environment at the moment.  Floppy disk and MFM drives
are currently slow, and may not even work in the 2.0.30 kernel.  They
have even been known to wipe out his drives a couple of times.

Ok, so for those of you who have been saying 'the Web pages appear to
indicate that it is available':  They have not.  If anyone did read the
top of the page that details downloading (where there was a 'Read ME NOW'
section, which it appears to be customary to totally ignore, as are
README files on FTP sites), then people would have realised the reason
that certain directories on the FTP site were not accessable and not
available yet - in the README on the FTP site, I state quite clearly
(the whole README file is reproduced here for those who haven't read
it yet):

Directory of /pub/armlinux/distrib
----------------------------------

This is the initial upload of the new Linux installation / kernel system.
Please note that this is mostly ALPHA, and as such, may crash, do odd things,
or even screw up your hard disk.  You have been warned!

Note!  Certain directories may be locked against public access.  This is
intentional, since they're probably empty.

kernels                 Precompiled binary kernels
riscos                  RiscOS utilities for ARM Linux
tools                   Development tool patches for ARM Linux

So, the current situation is:

a) I have an arrangement with EESOX to produce ARM Linux CD ROMs.
b) I am currently extremely close to producing a CD ROM based installation.
c) I have access to a CD Writer at work to write 5 or so CDs.  These will
   be used to test the installation, and then I will approach EESOX to
   produce a silver CD ROM.

I am currently looking at around 1 weeks more work before finishing first
CD ROM image.  It will then take two days to move the CD ROM image to
work (via ZIP drive).  I then see 1.5 weeks testing, and then negotiation
with EESOX for CD ROMs.

This timescale will definitely change if I have to visit Coventry next week
to satisfy work commitments, since it may mean that I loose a couple of days
or more to install a PA system for system integration.

>From my web pages, I have around 305 replies to my CD ROM counter.  Lately,
it has been non-functional due to some reorganisation at cymru.net, the
nice people who are providing the CGI script to process your replies.  Since
I don't use the web counter, I rely on people letting me know if something
doesn't work.

As you can probably see from the date that this mail was sent and the times
mentioned above, I'm probably overworking considerably for this project,
and it would be such a shame to rush it, and risk loosing the project.

Basically, what I am trying to say is that ARM Linux is nearing release,
but it will have to come at its own speed.  If it takes 3 weeks, it will
take 3 weeks, no less.  It may even take more.  I cannot stress enough
that you must be patient.  If not, you could end up waisting a hell of a
lot of time - both yours and mine, and phone bills as well.

There is, however, one way to speed the release of ARM Linux up - employ me
to port it!

Thankyou.  I'm now going to get some sleep, get up, go to work, return home
at around 9pm, have dinner, and recommence work on the ARM Linux distribution
around 10pm tomorrow.

Please address any hate mail to /dev/null.

If it has all the bits on it, its useful for getting stuff fixed.

Fortunately in about 4 weeks you will be able to work 40 hours and tell
your employer thats enough, and they wont be able to fire you for it.

So long as people are warned this isnt a problem, the original sparclinux
trees came with big "Hazard" signs on them and people did eat disks, but
they found the bugs!

Personally I'd still rather have the "Doesn't work don't bug me bug
arm-linux" code tree up somewhere. Let Phil put the first one out as
a "Development snapshot" - cos believe me its far far more ready than
the mklinux HP-PA development snapshot 1 !

I wasnt anticipating someone using it for that - it'll be on a pretty

That is simply not true.  Let's think about this a little more rationally,
shall we?  There is about 200MB on this CD, I gather.  Of that, the vast
majority is code that in all probability _will_ work fine.  Probably there
are bugs in the bootloader - probably there are bugs in the kernel as
well.  However, the reason people _want_ the CD is to avoid having to
download masses of precompiled binaries over slow links (even assuming the
binaries were available in the first place).  I'm sure they could cope
with downloading a replacement bootloader or a new kernel.  Perhaps some
of them can even fix the bugs themselves once they have a system that at
least works.

Nobody is pretending that this is a polished distribution.  By all means,
we should document the bugs.  But we should _not_ hold everything back
just because you're not sure it works properly. 

I think there are about seven people who have asked me to cut them a CD.
Even if they all mailed you I think you'd be able to cope.

There is another way which you have been ignoring for the past four years.
If you were to actually release source code so that other people could
work on the project, rather than trying to do it all on your own, things
would move forward an awful lot faster.

While I have every sympathy for your being overworked, it is entirely
through your own volition that you work on ARM Linux, and positively
against other people's wishes that you try to be the only person doing so.
Frankly, this is (a) bad planning, (b) insulting to the rest of the
community and (c) starts to give rise to doubts about your motives.

Incidentally, people who _have_ sent me cheques - don't worry, I haven't
cashed them yet, and obviously won't until I'm ready to actually send the
disks.  Sorry about the delay.  If anybody feels that in the light of what
Russell said they'd like to cancel their order for a disk, just let me

Thinking of which, I just built a binary distribution of binutils 2.8.0.3
to cross-compile for arm-linuxaout from x86.  You can get the tools from
ftp://kc.london.uk.eu.org/pub/arm-linuxaout-binutils-2.8.0.3.i386-bin.tar.gz.

I hope these are a bit less buggy than the old 2.7 tools were.  Let me
know of any success/sob stories.  By the way, there is still a problem
with the assembler and immediate constants ('#' is a problem if you go
through the preprocessor).  I think the solution is to modify as to make
'$' a synonym for '#' - if anybody feels like doing this then please do.

We want a pile of binaries out there which people won't even be able

I agree.

What I'm looking for on the CD is:
	source to kernels
	source for development utils (gcc, asembler, linker etc)
	source for other utils
	installer, bootstrap loader
	(anything else I've forgotten (; )

Assuming the development utils, such as the cross compiler, can be
built using a 'standard' linux-ix86 installation, then prebuilt binaries
wouldn't be necessary; they would save a bit of time though. Same for
prebuilt binaries of kernels and the other utilites.

What the CD will do, however, is give us a 'standard' distribution, 
we all start at the same place and can refer back to it if neccessary.
I'm prepared to download patches to the above when they start appearing,
but at 28.8k I don't what to try and download everything.

I wouldn't say that the vast majority of bugs are in the bootloader/kernel.
They do appear to be extremely stable.  There are a few nigglies in there, of
course, but I'm not too concerned about them.  What I am concerned about is
giving away a totally untried and untested set of packages, which for all I
know would be a total failure and a waste of my money.

I have now received this hard disk from Acorn, and last night I did try
installing what I have done.  Lets just say that what it installed wouldn't
have worked at all.

I did not ignore this initially.  When I started this, I asked several
people, and put an announcement on the net, asking if anyone would like
to lend a hand with the project.  What reply did I get?  3 people from
Southampton, one of which attempted to port the kernel to his RPC600,
but couldn't carry on with it.

Ohh no.  If you think that then you've got the wrong end of the stick.  The
*last* thing that I want to do is to be the only person working on it.  I'd
like people to be working on it.  I learnt from my previous release for the
a5k that if you do put something up (and that took me 3 hours work on a
directly connected ethernet), there are still a hell of a lot of people
who will complain.

I've been putting up kernel patches for a long time, so that people can
work on it.  I've said that there is incomplete ARM600 nor ARM700 support
in there.  Do you think that I've received any requests from people wanting
to put it in?  One, and nothing came of it.  I haven't heard from him again.
So, is it me not allowing people to work on it?

>From what I've seen so far, people are all too keen to say 'Yes, I'd like to
work on such-and-such', but when it actually comes down to it, nothing
happens.  I've seen this too many times.

Ok Philip, you genuinely want to help, and have been wanting to help for a
long time.  You've sent me patches etc, which I have incorporated.  You
suggested the RedHat package manager, which I have followed.  I've speeded
up the console code, as you've asked for.  Every time you ask for something,
it stops me packaging up the binaries and source code to send out.

People *can* work on ARM Linux right now if they want.  All the patches for
gcc, the kernel, binutils have been on the FTP site for a long time now.
I know that the libc patches aren't there.  Even if they were, they wouldn't
be compilable under the 2.0 kernels, and that is known by the Linux community
at large.

What has become apparant is that people want a proper distribution.  They
want the binaries to be supplied to them, not patches.  They don't want to
apply patches.  The net result is where we are now - three people working
on ARM Linux.

It is not insulting to the community.  It is insulting to me that I have
supplied patches and such like, and then only two people pick up on them and
use them.  That's really insulting.

The packages have, on the whole, been tested by RedHat and thousands of
users across the world.  If they don't work properly on the ARM then the
most likely cause is a bug in some part of the ARM system, not in the
package.  In any case, I'm prepared to run the risk.  As Alan and I have
both said, it doesn't matter too much if there are bugs - in the worst
case, even if the CD _is_ only good as a coffee mat, people have only
spent a few pounds on it.

That's how it goes with these things I'm afraid.  When I started the hp300
port, I also posted to the net and got precisely no offers of help. 
Several people said "hey, that's a cool idea - let me know when you have
something that works, and I'll help then" but nobody wanted to help with
the gruesome business of hacking the low-level kernel code so that the
thing would boot.

You haven't made it that easy.  Kernel patches are all very well but
people need to be able to try out what they do.  If I hacked the kernel to
add ARM6 support today (and I don't imagine it would take long), what
would I do with it then?  I'd have a kernel image that I hoped would work,
but no way to boot it and no binaries to run under it even when it _was_
booted.  There is a certain body of code that people need, ideally in both
source and binary form (though just source would do) and that includes the
kernel, the C library and the bootloader.  Yes, you've released the kernel
but you haven't released anything else.

I'm sure we can work around that.  I very much doubt it's a big problem.
The Linux community at large isn't interested in libc4 any more, so we
can't really expect them to help.

Yes, people in general want an easy life.  That doesn't mean they don't
want to help with writing the code (many people have mailed me saying they
do) - just that they don't want to have to go through a lot of pain and
suffering to do it.  Cross-compiling a kernel seems quite straightforward
to me, but then I've compiled thousands of kernels before.  Cross-building
an entire system to the point where it will boot and they can log in is at
best an awful lot of work, even if you know what you're doing and have the
hardware available, and at worst extremely difficult.

Now, when we spoke on the phone on Monday evening you told me that my
SyQuest was packed up and ready for you to post the following day.
Assuming that really was the case, and it has at least some version (even
if it's slightly old and buggy) of everything that people need, please do
what you said you would and post it to me.  Then I can cut the CDs,
everybody can install it and we're all happy.  Nobody who isn't on this
mailing list is getting a CD, so they'll all have seen the amount of grief
that has been involved in having them made, and I'm sure that if you don't
want to be sent bug reports they will respect that.

Frankly I don't care _what_ we have.  I'm not about to spend hours
packaging everything up neatly, but I'm certainly not prepared to
deliberately unpackage all the binaries we've already got just to make it
difficult to install.

Let the users install it if they want.  So long as people understand that
the mailing list is their only source of support and nobody is obliged to
help them (though I'm sure people will) we'll all get along just fine.
You and Russell seem to be blowing the "naive user" problem up out of all
proportion.

I have done, for the ix86 at least.  You can find them in the same place;
the filename is:

	binutils-2.8.0.3-arm-linuxaout-970510.bin.i386.tar.gz

You need to untar this under /usr/bin and make appropriate
links in /usr/arm-linuxaout/bin.

Here are some patches to go on top of Russell's 970505 2.0.30 patch.  I
need the first two to build successfully, and the third removes a `tr'
call that is no longer needed if you use the new binutils.

Hi guys.

I've made a new arm-linux patch for binutils 2.8.0.3.  This one should
allow you to use '$' instead of '#' to introduce immediate operations,
which is handy if you need to preprocess your code (cpp barfs on '#') -
this will affect all arm configurations, not just linux.  Please check it
out. 

You can get the patch at 

	ftp://kc.london.uk.eu.org/pub/binutils-2.8.0.3-arm-diff-970510.gz

I'll make binaries later if I have time.  HJ, can you include this in the
next binutils beta release?  Thanks.

Hi guys.

I just sent some more patches to Ulrich to improve the ARM support in
glibc, for both arm-linuxaout (ARMLinux) and arm-none (embedded system)
configurations.  They should be in the next snapshot.  If you want to look
at them now you can find my diffs against the 970511 snapshot at

	ftp://kc.london.uk.eu.org/pub/glibc-arm-diff-970511

There are still some functions that need writing, notably clone().  If
anybody feels like doing this please say so.

Well one thing you can do Phil if you are temporarily paused is to build
an a.out libc5. Ok we lose the dyanmic link -ldl stuff but I don't see why
a bit of GBH wont make the rest of it build a.out ;)

An installable selfhosting system (however wobbly) is an important step
forward for people with only Arc machines.

I thought of that, but it didn't really seem worth it at the time.  I was
hoping that with only a bit more work I could build an a.out glibc, and we
could skip libc5 entirely for the ARM.  In terms of the glibc library code
I think about 90% of it is done now - we don't have the crt startup files
yet though.  Nor does it do .sa a.out-style shared libraries, and I'm not
totally sure whether that's worth putting in or not.

Is there any reason why libc5 is particularly desirable?  I was working on
the assumption that we just wanted something better than libc4.

I've put a copy of the contents of the CD at

	ftp://ftp.london.uk.eu.org/pub/armlinux/

I don't know how long it will stay there though.  I think Alan is
planning to make the CD available as well once he gets it.

No precompiled binaries are included on this CD.  You need access to a
machine to cross-compile from.  Russell didn't provide me with any
binaries and I don't have time to build them all at the moment; it seemed
better to get what I had out than wait even longer.

For people who just want to _use_ the system rather than develop it, I'll
try and do a second CD sometime in the future with binaries and some sort
of installer.

Ok many thanks Russell. I'll see this lot gets put up where its accessible

Dunno. Things are going rather slowly since, IIRC, Russ is bogged down 
with a "real" job. 

I'm having problems getting the a5k kernel started on my A3020. For some 
reason, the kernel uncompresses ok sometimes, but other times gives an 
"invalid compressed format" error. I can't isolate what makes it work and 
what breaks it.... anyone had similar experiences?

cheers

Actually despite that Russ has managed to get most of an ARM Red Hat 4.0/4.1
system packaged! [For non-linux people, Red Hat is one of the popular
distributions. It's by far the best which is why I originally suggested Russ
used their tools and system. ;) 4.1 is the latest version, the ARM one Russ
has made is a hybrid with 4.0 approx.]

As to the 700 version - there isn't one yet because Russ doesn't have a
600/700 and I haven't got the sources. He's is supposed to be visiting me
this weekend with all the bits (otherwise I'll visit him with a baseball bat
;)). My machine is a 610 so by next week there MIGHT be a real Red Hat
distribution on the ftp site [I have out of hours ethernet access] which
supports at least ARM600/700 and SA. Otherwise Russ might have a few bruises.

Now now, be nice =c)
	So there IS a release of the new armlinux kernels around! I 
haven't heard anything at all about it and was giving up hope. Two 
questions.. 

a) Does this release include the ethernet code for ALL types of ethernet 
card usable on the A5000? I ( a long time ago) tried to install the net 
release disks for the 1.3.35 kernel and it didn't work because Russ only 
had the manufacter's ID for his make of ethernet card, while mine is the 
same kind, but made my different people. I can't remember the exact 
details but I supplied the info Russ needed and he said he had put it in. 
Unfortunately he's been so busy that no new kernel has appeared on the 
ftp site so I've been waiting in vain for a long time =c(.

b) How can I get a hold of this distribution?

hang on! I thought of another question! =c)

c) Does this distribution include the strongarm kernel? I know somebody 
with a 40Meg strongarm (that's 40M of memory *slaver*.. us poor students 
make do with a 4Meg A5000 =c).. which would zip along with linux quite 
nicely =c).

  Well.. that's quite enough typing.. I'm off..

That's probably because you're on the wrong list.  For anybody else who's
still using the tardis list, all ARMLinux discussion has been taking place
on the vger list for several months now.

There is almost all of the "new" stuff on the ftp site now - kernels for 
a5k and strongarm, along with loaders, partitioners and whatnot. All that 
we are waiting for is the boot and installation disks, which according 
to Martin will appear this weekend - nice one chaps! The problems I have 
mentioned with decompressing the kernel occur with this new 2.0.28/29 a5k 
kernel - anyone else experienced this?

I had the same sort of problem with the 1.3.35 net kernel - my ANT 
Ether3-8 card was recognised, but things didn't work when I tried to take 
it up with ifconfig - device not found errors, IIRC. Hopefully, this has 
been fixed....

BTW, if anyone has tried out the cross-compiler which is pointed to by 
the arm linux web page (can't remember offhand who ported it), I found 
that cc1 (the compiler backend) was broken (using a Pentium), and so I've 
recompiled it. I can't garauntee it works completely, but if you want a 
"fixed" version try ftping to ftp://ftp.star.ucl.ac.uk/pub/rhdt/cc1.tgz

The only reason linux on the ix86 took off at all was that the source 
code was freely available so that people could work on it - without 
the source code, the ARM version of linux is just going to die, since 
only one person can work on it. The reason linux works at all is that 
it's free, so *anyone* can work on it. That's the whole point of the 
bloody thing - we'd be using RiscIX if we wanted a supported, 
you-can't-do-anything-to-this product.

So, surely you could release the source code, even if you have to 
stick a great big "Do not email me about this" all over it - the 
number of people who'd be working on this isn't so large it would be 
a problem anyway.

It would be "extremely foolish" of you not to release the code when 
there's a reasonable number of us here quite prepared to help, if we 
can only get the source to work on.

I'm sure Russell will release the source code, _when_ he's happy with
it (You will, won't you Russell?). I agree with him that it would be
extremely foolish to release it when it has a large number of (possibly
known) bugs. Even with a few people working on the same code, it could
easily get unmanagable.

And of course there could be a hush-hush fancy big-wig deal going on in
the background we all don't know about with some big company.  Yes, I
can see it, ARM-Linux, the new industry standard. SUN files for
liquidtion as Solaris shares crash on the NASDAQ stock exchange.  Oh
yes, oh yes!!!  Russell, lets here it for ARM-Linux!!! :P

Well the CDROM #1 is currently uploading. It should be on the end of a
2Mbit line by Monday. It doesn't have the X stuff on it but there is enough
to keep you all busy and out of Russell's hair for a while tidying this
lot up.

I'm  not prepared to create an incoming and don't have a lot more space
on that machine for more than the CD image but I'll try and get something
nicely sorted out with the ftp.uk.linux.org folks soon

Can you be more specific about the error?  It would be good to know the
exact text of the error (I couldn't find the one you described anywhere in
the kernel source) and a better idea of _when_ it happens.

Hi.

I have been trying to install linux on my StrongARM'ed RPC, but when the
kernel loads, I get a strange error: Something like "Illegal magic (some
address) in bmap file - aborting" why do I get this error?

Thank you!

If you've got intermittent problems I'd try booting it from a completely clean
system each time; boot with shift held down to make sure there is nothing
else in, and then ctrl-shift-f12 twice (if you weren't
already at a prompt).

Now - does it always produce the same results if you do that?

Both lists had been quiet lately, so I thought that nothing much was
happening...

I guess my sub to the vger list has been dropped for some reason, and
since I've lost the instructions for that list, could somebody mail me
them please?

OK. Here goes:
Here is a copy of SCSI::Main.$.!Boot.Choices.Linux.Config:

# Linux Boot Configuration file
# *** This file is automatically generated by !LinConfig - do not edit!!! ***
# List kernels at startup
List:		off
#
# Partition containing kernels
Root:
ADFS::IdeA.$.Linux.rpc-2/0/30
#
# Partition List
Partitions:
0301 $.Linux.BootDisk
0301 $.Linux.Part1
0301 $.Linux.Swap
0000
0000
0000
0000
0000

The BootDisk partition is a Partition I found under /old/ (I think) on the
ARMLinux ftp-site. The two other partitions are made manually and contains only 0's (that's ascii 0). I have a Powertec SCSI-II card on which HD my BootLoader
software is on, but I don't think that that card is supported (yet?). The two
empty partitions are just test partitions and are only 10MB a piece.
The problem is when I double-click on the !Linux app then the program returns a
"Invalid magic (EA000006) in bmap file - aborting"-error. This is as much detail
as I can give you. I hope it is enough?

Thanx!

Hi,
  Russ and myself have just spent the last few hours getting Linux
going on a RPC with a 610 - its not thre yet, it needs the abort
handlers doing.

But one thing which has come up is that the libgcc.a in the cross compile
binaries on ftp.compsoc are wrong when compiling for the ARM6/7/etc - they are
still trying to do some MOVS PC,... or LDM ^'s.

I'll fix it over the weekend - or you could do it the real way like we did
with Zap....

Is there actually any way to generate a libgcc.a that will work with both
architectures?  If not we probably ought to try to find some way to do it
by having two of them and altering the specs file. 

Also, what's the situation with moving user binaries between arm3 and arm6
machines?  E

Oops - yet again I pull off a no-brainer. On a completely clean machine 
(booting to the CLI) it runs without errors. Duh! Should have thought of 
that. I was considering my m/c to be "clean" after rebooting into RISCOS 
with no filer windows opened or apps booted, but that does not appear to 
be clean enuff. Cheers!

One other problem I have is the !Config app - it appears to lock my 
machine every time. Any suggestions (obviously I'll have to boot into 
RISCOS to use it)

If I build a binary on an ARM3 machine (using -marm3) and try to run it on
an ARM710, say, which of the following will it do?

 - work correctly
 - silently go wrong
 - refuse to execute

That's what I thought.  In that case we should possibly provide some
mechanism to stop people falling into this trap.  Subtle condition code
corruptions could cause some quite insidious bugs.

Oh, right.  I thought Linux ran everything in 32-bit mode if it could.  I
don't have an ARM6 machine here to try it on though.

Well that depends what you meen.  libgcc.a actualyl has two copies built
so that lib/gcc-lib/.../m6 contains the one for the ARM6 and .../m2 contains
the one for earlier machines and the OS.

The only difference is the question of how to end a procedure, so on an ARM6
you do:

MOV PC,R14 or a plain LDM ...{ ...PC}

on an ARM 2/3

MOVS PC,R14 or LDM ...{...PC}^
which causes the flags to be preserved accross the function.

The same instruction on an ARM6 will cause the SPSR to be restored to the CPSR
which reaks havoc if you happen to call this in the middle of some particularly
mundane kernel code (in this case the bit doing a division to calculate the
time).

Good question! Lets ignore kernel code for a minute (because that definitly
would fail). If you exit a function with 

MOVS PC,R14

in user mode on an ARM710 the results are probably undefined, but in practice
it will probably survive and just not restore the flags.  So the net effect is
that the code will survive but the flags will have changed over the course
of the function.  Now I guess (but don't actually know) that there are fairly
few places which actually depend on flags being preserved accross a procedure
call so if your really lucky it will execte correctly. But it could
just go wrong.

Now of course the catch here is that if the ARM710 is running full 26 bit mode
then it will quite happily execute the ARM3 code. Now I think Linux does that -
but in that case things should becompiled with -m3.

Since the two architectures /are/ different, it would make sense to have
two different magic numbers - one for 26 bit code and one for 32 bit code.
It would then be possible to have a binfmt_aout26 module that would do
the necessary magic to run the app in 26 bit code space if you weren't
going to run 26 bit code often.  As far as I can see, this should be
a matter of setting the appropriate bit in the CPSW to set the flag.
32 bit data should still be okay, I think.

An alternative measure would be to compile all code for 32 bit - it
will run on all machines; the only problem will be that it's slightly
less efficient.

Obviously, that's not terribly good for the kernel; I think we should
always have a specific architecture set up for the kernel - since that's
the least of the worries.

That's basically what I was thinking.

Of course.  Given that the drivers and so on need to be different,
compiling for a specific CPU is a trivial matter.  But people ought to be
able to take a user binary of unknown provenance, and either run it in the
knowledge that it will work correctly, or (at worst) get an error message.
Random lossage is not an acceptable option. ;-)

I'm wondering if the right thing to do is to move to fully 32 bit in
the 2.1.x series when we move to ELF.

The thing is the old machines (A400's etc) just aren't going to be
able to cope with ELF; with only 128x32K pages and the extra page
dirtying ELF is supposed to bring I don't think they stand a chance
unless you are the lucky ones who have 8 or more MB in the old
machines.

I don't know if this is the right thing to do.

I don't thinkn that's necessary.  It isn't actually necessary for programs
to execute code out of the 26bit limit - what was the last thing you
developed that had a 64MB program size?  It would make sense to compile
things in 26bit compatibility mode as they execute slightly faster (due to
the need to make fewer comparisons round function calls) and are slightly
smaller.  I would emphasise that this is a very slight difference.
Probably less than 0.5% for big programs.  But if ELF does require double
mapping of pages as Russell indicated he thought it did, the old machines
are stuffed for ELF.  So, targets for gcc of:

arm-linuxaout (26 bit code produced.  libc4)
arm32-linux (32 bit code.  libc 6)
arm-linux (26 bit code.  libc6)

It should only be necessary to select between 26 and 32 bit code when
doing the kernel, to be honest.  Oh, I keep changing my mind what the
Right Thing To Do is ;-(

I think this is the wrong thing to do.  Supporting 26-bit mode doesn't
cost us much and we don't want to leave people with no machines without
any support at all.  The only ARMLinux machines I have at home are ARM3
vintage; frankly I'm not about to rush to spend 1000 pounds or however it
is on a RiscPC.

Can you quantify this "extra page dirtying"?  I suspect there are other
things we can do to improve the situation though - ELF will let us have
more shared libraries, for example, and we can do the trick of discarding
the kernel's init code.

There's not a lot to support.  Binutils should be able to cope with Thumb
now, I think.  If somebody builds a Thumb machine then we could port Linux
to it.

Actually I was thinking of buying the StrongARM/PCI development card
- they were suggesting they'd be under #400; not quite a full
machine mind you - but more hack value :-)

I've forgotten exactly _why_ ELF is thought to require `double mapping of
pages'.  Can somebody explain it?

With 32k page sizes, that isn't going to save much.  Maybe one page if you're
lucky.  The kernel will still take 20 pages...  There actually isn't much
init code that can be removed (I think it's about 8k or so).

Arghhhh! Any hope of this working in sight? If it means anything, all of 
the driver code is in the Ether3-8 module which comes with the Acorn DCI4

Under ELF, especially on the 386, the intermediate page between text and
data is mapped in twice - one after each other.  This cannot be done under
the MEMC (since it uses a one to one physical -> logical mapping).

The only way that you could do it is to immediately create one extra dirty
page extra on top of the dirty pages caused by dynamic linking (if used).

I don't believe that it would be a good idea to do this to an already
page-starved architecture.  ARM6, yep. ARM2, 3.  Definitely not.

ARM3 code will run on ARM6, ARM7, ARM8, SA110 with no problems under linux.
There is no need to complicate the issue with different magic numbers!

If you do go to 32-bit aout binaries, then you WILL have problems on ARM3
machines.  The problem is not obvious, but basically if you use shared C
libraries on 32-bit, they will be located at 0x60000000, which is, obviously,
an invalid address on ARM3.

The solution is to set a flag in the a.out header to indicate 32-bit.  That
way, there is absolutely no need to change the binutils (apart from setting
said flag if you're using 32-bit).  *Nothing else changes*.

Simple solution isn't it?  And it involves the least work!

If you don't use shared libraries, then the binaries do tend to turn out on the
large side (~100k each), and this is definitely not desirable, especially when
trying to build boot disks and the like.

Martin - Over the last day, I was able to visit Dave Gilbert (@ Manchester Uni,
curtesy of certain business arrangements), and tried out the RiscPC kernel on a
RPC600 with Arm610 in.  We've sorted out some bugs concerning the 'Updatable'
bit, so it should at least boot.  However, it's just the abort code that needs
fixing...

My gcc patches create the gcc 'multilib' - it will generate libgcc.a for arm2, 
arm3 and arm6.

Binaries will work on either machine.  There are plans to have 32-bit binaries,
and obviously 32-bit binaries can't be moved to an ARM3 machine.

You require libc 5.4, not 5.3 to use it.  (Is 5.3 broken in a severe way,
or what?).

Dave and myself also found that m6/libgcc.a is broken.  Dave's going to have
a look at that over the weekend.

Not bad so long as it has the CPU and RAM on it and fits a PC. You could
make a very nice 4 node NUMA cluster that way, and have a supervisory 
intel CPU.

There is no requirement to map it twice, so you can avoid that by careful
alignment of sections.

You should be able to get all the dynamic linking, GOT etc in one page
surely  (especially at 32K pages)

No, but binaries compiled against 5.4 won't run with 5.3 or earlier.

Just because the 386 does that doesn't mean we have to.  I have the ELF
specs from Sun's manuals here and they don't say you have to double-map
pages.  I think this is a non-issue. 

If necessary I imagine we could force the data section to be page aligned.

One page is still significant when you've only got 128.  I get something
like 24k thrown out on my PC and my Alpha at the moment, and not all the
drivers have the __initfunc()s added yet, so I'm hopeful we can save at
least a page or so.

Talking about memory; I can remember speaking with Russell at

on the older machines was either (a) not written or (b) no tested.
What is the situation here?

Nor is putting a.out shared library support into glibc, to be honest.  I
think people who want shared libraries can wait for ELF or use libc4.

Just wondering if the ARM6 kernel code is late or early abort - ie is all
the chatting about ARM6 compatibility also referring to the ARM7.  I
realise that the basics of the two processors is the same - the
'abortedness' being the only difference I know about :)

I wait with baited breath to reformat my HD and install linux-arm7 :)
(will I suffocate :)? )

Take care,

Matt

Hang on - so what you are proposing is having 26 bit Aout, 32 bit aout and then
ELF. Hmm.
Why not just have 26 bit Aout and 32 bit ELF?

I'm not sure thats true.  Is there any reason why we need 32 bit a.out?
I believe that 2 file formats is better than 4.

If we can get ELF working in a reasonable timeframe then no, we don't
really need 32-bit a.out.

I think we will probably need all four combinations - 26 bit a.out, 26-bit
ELF, 32-bit a.out and 32-bit ELF.  As I said, ARM3 machines absolutely
need 26-bit code, and new ARM (eg Thumb) absolutely needs 32-bit code, so
there's no getting away from that one.  Also we need a.out and ELF, and
since binary format is pretty much orthogonal to the generated code
anyway we might as well go the whole hog.  

Can you think of any particular reasons why this is bad?

I sounds a bit late to offer, but I have a couple of spare 610 cards if
anyone needs them for testing. Great news about the release. How big is
it likely to be? How stable?

I'd like to add my voice to those who have raised issues about the 
shortage of memory in 4Mb machines. With so little memory, the limiting 
factor on "real world" speed is not the CPU but the swap rate; using the 
1.3.35 kernel, my A3020 swaps like buggery and so it would be nice to 
retain as much non-kernel memory as possible. Even though A3020's and 
such are now getting towards "legacy" hardware, they are much in use and 
it would be a shame if they got passed by in the rush to provide for the 
latest-spec whizz-bang machine....

On a similar note, how much "non-essential" stuff is there in the kernel 
which can be chucked to free up memory (ie things like sound, ISO 
9whatever support for CDROMs etc)?

cheers

Did Russ visit? Or is he a bloody pulp now? In particular, any sniff of

He most certainly did. And what's even better we've got Linux running on the
ARM610/710 as well. Most of a red hat distribution is up on the ftp site,
though you can't get to it yet. Expect it in a week or so I guess.

I've now got ARM Linux installed on mine, and while not being perfect, it's
damn good. I compiled the GNU Emacs 19.34 RPM up last night without much
bother. I'll upload it in time for the dist becoming available. There's a few
other things missing but not much.

Okay, three points here:

1. Is the ARM/RedHat setup authorised by RedHat itself? This may have
   been discussed on the vger list, but I'll have missed it, cos I've
   only just re-subscribed...

2. I hope the release that's (virtually) ready will still come out soon.
   It would be a shame to wait for it to be 'upgraded'.

3. Does anybody know what the differences are between the current
   (Intel) release and (Intel) 4.2?

I did visit indeed, and yes, I've uploaded all the bits'n'pieces now
(but not for general consumption).  Eg, they won't work on the old
machines atm (I've got to produce a set of 720k boot disks for them).

However, Linux now works on ARM610 and StrongARM.  ARM710 is unknown, but
shouldn't be far off.

We did find a few missing files in the distribution, but that should be fixed
now...

The release is almost finished...  Please stand by.

By "not for general consumption", do you mean unavailable, since there is 
nothing new on the web site re the installation disks (although the 
private directory has changed - which of course, we can't get at!)

Most of the CD is now on ftp.uk.linux.org - its taking time as it has to
be done in bits by hand for various reasons. I'll be able to add stuff to

I have (more or less) sucessfully built a kernel on a mate's Pentium 
using Dave Gilbert's cross-compiler (after getting my mate to upgrade to 
libc 5.4.x). However, the build falls over in the final step when making 
vmlinux with the following error:

Hi guys.

If anybody feels like doing a small amount of work on GCC, it needs fixing
so that aliases in general (and weak aliases in particular) work for
Linux/ARM a.out.  You should be able to copy the code from the NetBSD
a.out routines, so it ought not to be too difficult.

This is the current major obstacle to having a version of glibc that
works.  The library itself now all compiles successfully for arm-linux,
and most of it works for arm-none as well.

p.

Just go through "make config" and see for yourself.  The "old IDE harddisk
driver" is smaller than the "enhanced" one, so you might want to use that.
Make sure you haven't compiled in support for any SCSI cards or network
devices that you don't need. 

Remember that you can use modules for things you need infrequently, so
they only take up space when you're using them.

ELF.  Is the reason for mapping it in twice on the i386 in order to try
and write protect the text while leaving the data writable?  If so, that's
going to fail on the ARM.  In fact, it will fail quite badly. due to the
lack of internal cache snooping type stuff.  If a page is double-mapped,
both pages must be marked as uncacheable which will have a severe
performance hit.  I propose leaving the last page of text writable which
does mean that programs will be able to screw themselves up, but it's
better than having to take a protection violation trap and having to
figure out whether or not it's correct and do the write in the kernel if
it was correct.  The chances are fairly low anyway, i think, any program
which overwrites its own text is more likely to crash shortly than it is
to do something Undefined and Wrong.

One nice solution does present itself though.  On a ARM6+, we have
subpages which are 1k in size (assuming we're using 4k pages?)  It
wouldn't be hard (in fact I believe the RISCiX backend for the binutls
does it already) to persuade 1k alignment and it wouldn't waste too much
space.  Protection levels can be set on an individual subpage.

Oh, I guess that one possibility would be to physically copy the whole of
the last page.  But I'm very unkeen on that idea!

Erm, "old" IDE, not enhanced, and no MFM stuff. And yes, this was 2.0.30. 
This was compiling for my A3020, with the IDE interface on the 
motherboard.

Ugh.  It looks like something went wrong with the hd driver when Russell
converted it for the ARM.  You may have to use the new IDE one after all
for now - though defining HD_TYPE to something sensible when you compile
hd.c might get you going.

Right, my last problem with kernel building has been cleared up (cheers 
Russ), and non-compressed kernels now build ok (haven't tried one out, 
yet, though). However, I have a new problem building compressed kernels. 
The actual kernel builds ok, but things go wrong when it is being 
compressed (I think!):

---
make[2]: Entering directory
`/tmp_mnt/zuaxp8/export/user6/mp/mother_temp/rhdt/linux/arch/arm/boot/compressed/

<snip> 

/usr/arm/tools/bin/arm-unknown-linuxaout-gcc -D__KERNEL__ 
-I/temp/rhdt/linux/include -O2 -DSTDC_HEADERS -m3 -c misc.c -o misc.o
misc.c:10: string.h: No such file or directory
make[2]: *** [misc.o] Error 1
---

It appears that the standard headers aren't being found properly - does 
anyone have any idea what's going on? This is building 2.0.29....

cheers

On Friday, I decided the time had come to actually start running Linux/ARM
myself.  So I downloaded pretty much everything in sight from the ftp
site.. problems: 

The patch against gcc 2.7.2.2 doesn't apply cleanly - some of the patching
appears to have already been done.  This *was* against a clean untar of
2.7.2.2 that had been patched from 2.7.2.1.  And the t-linux fragment
needs to have CROSS_LIBGCC defined, not LIBGCC.  or something similar. 
Knew I should have written everything down.  It's easy to deduce what went
wrong by comparing it against t-semi. 

The patch against binutils 2.7 applies (after I found a virgin copy of
binutils 2.7, any chance of a patch against 2.8 any time soon?) but it
refuses to link the bfd/libbfd.so.2.7.  The Make crashes somewhere in
opcodes directory complaining about multiple symbols defined.  It works
fine for an arm-semi-aout target. 

And the a5k kernel provided doesn't work.  The bootloader complains about
bad magic (EA000006) and refuses to boot it.  The first word in the kernel
is indeed a branch instruction.  I tried executing it under RISC OS, but
it addressexceptioned and a few minutes later my machine hang.  Not
terribly surprised, but I thought I'd try it. 

BTW, does this kernel support netbooting?  The only supported device I
have is an Acorn Ether3, linked to a 486 Linux box running 2.0.30, so I
was hoping to NFS mount my root partition.  Yes, I'm on an A440 so no
device drivers are available.  And is the source code on the ftp site?  I
didn't see it, but I may have overlooked it.

I'm going to make my copy of the mailing list archive available as
ftp.barnet.ac.uk:/pub/Acorn/armlinux

It's nothing fancy, just available.  And it's only what I decided worth
keeping.  And its only since I subscribed.  Please, someone do something
better than this.

Oh, and Jogu, this spamming appears to be a new technique - Stewart Brodie
possibly got hit the other day.  I'm contemplating a comp.risks posting.

I found the 2.0.30 patch set last night (I was looking in the wrong place.
mea culpa) and installed it into a copy of the standard tree.  Patch went
fine except that it tries to patch a file called something like
kernel.syms, which doesn't exist.  So I skipped it.

Is it supposed to be able to compile for non-RPC machines?  Just
wondering, since the very first file compiled fails with an error.  Also,
no distinction is made between ARM2 & ARM3, despite the fact that ARM3 can
SWP and ARM2 cannot.  Likewise, the config.in does not query for machine
type and assumes RPC.  I added the ability to query, and autoset the CPU
type based on machine type, but I'm not sure of the value of submitting
this patch back if 2.0.30 isn't designed to compile on these machines. 
Don't take this personally, Russell, I do appreciate the work you've put
into Linux, but if I don't report the problems that I find, they might
never get fixed.

Dear All,

Does anyone know what would I have to do to get ARMLinux going on an
A7000+, if I were to buy one? (i.e. what would be different to say, an
A5000) Will ARMLinux take advantage of the hardware FP in said machine by
default, or would I have to alter things?

Also: Whats the position on using a SCSI Zip drive?

Thanks,
David.

I have (hopefully) solved the problems I had building the compressed 
kernel. For those who might run into similar problems, I've prepared a 
very small patch which appears to fix things (this also tweaks a problem 
with the "old" IDE drivers which Russ has already posted a fix about).

The kernel I build appears to work ok (up until wanting a minix boot 
disk), and in a nice, minimal form swallows up not very much memory (when 
running on my 4Mb A3020, I have approx 3100K free, which is nice)

Email me if you want the patch....

cheers

Rich

Yup, snotty message sent back, ccd to postmaster@aol.com which included
the original drivel. 

What good it will do is another matter but it won't do them any good to
have the postmaster receiving tonnes of mail from various people
complaining about their mail.

Hi,

I'm just trying to install Linux/ARM on an RPC600 with a ARM610 CPU.
So far, I had no success. Could someone tell me, what I need and *where* I
can find it. It seems that the infomation on www.arm.uk.linux.org are
outdated and most files mentioned there are not present on the ftp site.

Thanks
   Andreas

vger appears to persistently drop my subscription - anyone else had this 
problem? Incidentaly, has there been any "hot" news in the last week 
which I may have missed due to a dropped sub?

Unless nobody's written a thing since the weekend (which I doubt, somehow) 
this has happened to me this weekend. I seem to remember posting a
question about A7000+ or something at the weekend and today is the first
day I've had messages since. (If anyone DID reply to my question, could
they possibly resend it direct to me please, cos I haven't received
anything for a week.)

Cheers,
David.

I don't remember seeing your question.  Can you repost it?

BTW, the most likely reason for people getting mysteriously dropped is
that email to your account started bouncing.

Dear All,

Does anyone know what would I have to do to get ARMLinux going on an
A7000+, if I were to buy one? (i.e. what would be different to say, an
A5000) Will ARMLinux take advantage of the hardware FP in said machine by
default, or would I have to alter things?

Also: Whats the position on using a SCSI Zip drive?

Thanks,
David.

It would probably work by default with FP.  ARMLinux uses a licensed
FPEmulator.

It ought to work straight off.

Hello,

I am a Linux newbie and want to install ARM Linux on my A5000
(maybe on my RiscPC/SA as well later). Unfortunately, two
archives are missing in the distribution package, instimg.arc
and suppimg.arc.

Can you please tell me where I can find it, or could you even
send me the two archives?

Thanks in advance,
