Illegal instruction

Illegal instruction

[Carsten Langgaard]

Hi Karel,

I have tried the root-images tar-files: mipselroot-rh7-20010606 and
mipsroot-rh7.
The mipsroot-rh7 (bigendian) root image seem to work fine, but when
I use the mipselroot-rh7-20010606 (littleendian) I get an illegal
instruction.
[cat:179] Illegal instruction 7c010001 at 2ac8b20c ra=00000000.

I'm using a 2.4.3 kernel.
Anyone got an idea ?

/Carsten

I'm still using 2.4.0-test9 on mipsel, because I've problems with the
newer kernels too.  I hope to test H.J. Lu's toolchain/glibc, but
currently it is much to hot to switch on extra computers :-)

 Weird, I'm using 2.4.5 for more than a week now on my /240 and it appears
to work fine.  I've built it with my old tools which I'm still using.

Hello Carsten,

I have seen the same thing on the same kernel version.

Is the userland compiled with MIPS I option?  I bet this is the same nasty
MIPS_ATOMIC_SET bug.

Currently, there are three fixes.  One is from Florian, which only takes care
of CPUs with ll/sc.  Another is from Maceij, which introduces a new syscall,
and some changes in glibc.  The thrid is mine, a compromising one.  It takes
care of both ll/sc case and non-llsc case, has minimum change, and practically
makes all programs happy.

Ralf, please take at least one of the fixes.  Even a not-so-good fix is better
than no fix.

This is a compromising fix for sysmips(MIPS_ATOMIC_SET, ...).  It
forces SIGSYS when the return value is a small negative value.  This
limit is OK for glibc.

Re: Illegal instruction

[Carsten Langgaard]

Thanks, that did the trick.
Now I would like to try to install H.J. Lu's RedHat7.1 RPM packages.
If I just do a:
    rpm -Uvh --root /mnt/harddisk *.rpm
then it fails on a lot of dependencies. If I try to force the install like this:
    rpm -Uvh --nodeps --force --root /mnt/harddisk *.rpm
then it actually install a lot of the RPMs, but still some fails, because it actually need
then dependencies.
If I try to redo the above it seems to go better the second time, because a lot of the
dependencies is solved (installed).
Is this really the way to install a set of RPMs like this or is there a better way?

Those rpms have to be installed in the right order. I have a set up
to do that. I will see what I can do.

Thanks, please do.
Another thing, I can see your distribution is lacking kernel header
files, I guess they are needed to do a native compile of the source RPMs.

Are you only cross compiling the RPMs.
It would be great, if you could put together a RPM containing the kernel
header files.

Updates on RedHat 7.1/mips

They are in install.tar.bz2 now.

I added gdb and kernel-headers. I also updated gcc, glibc and binutils.
The toolchain rpms are updated.


H.J.
------
My mini-port of RedHat 7.1 is at

ftp://oss.sgi.com/pub/linux/mips/redhat/7.1/

you should be able to put a small RedHat 7.1 on the mips/mipsel box and
compile the rest of RedHat 7.1 yourselves.

Here are something you should know:

1. The cross compiler hosted on RedHat 7.1/ia32 is provided as a
toolchain rpm. The binary rpms for the mips and mipsel cross compilers
are included. You will need glibc 2.2.3-11 or above to use those
rpms. The glibc x86 binary rpms under RPMS/i386 should be ok.
2. You have to find a way to put those rpms on your machine. I use
network boot and NFS root to do it.
3. install.tar.bz2 has some scripts to prepare NFS root and install
RedHat 7.1 on a hard drive.

Thanks.

Thanks a lot, that look like something we have been needing for a long time

Now that I'm at it :-)
Could you add a Perl rpm to you distribution, this also seems to be needed to
build the RPMs natively.

I also would like to do a cross build, but how do I do that ?
Do I have to change all the spec files, to set the target arch to MIPS, or is
there a easier and better way to do that ?
I guess if I just install the SRPMs and the cross toolchain, and try to build
out of that I will simply build for the build platform, which is i386.

Perl has to be built natively. I uploaded mysql-3.23.36-1.1.src.rpm,
perl-5.6.0-12.1.src.rpm, apache-1.3.19-5.src.rpm,
mod_perl-1.24_01-2.src.rpm, tcsh-6.10-5.src.rpm and
zsh-3.0.8-8.src.rpm. Just installed my RedHat 7.1. Then you can build
perl yourself. You may need to build/install the tcsh rpm first.

You need my patched `rpm' to do cross build. You also need some
specicial set up. I am enclosng a message of mine. I will see if
I can cleanup my cross build environment and upload it.

Although my source rpms do support cross compile, FYI, all my
mips/mipsel rpms are cross compiled from ia32 machines, the
unpatched rpm, that is /bin/rpm, doesn't support cross compile.
In my RedHat 7.1, there are i386 rpm binaries which support
cross compile. I have a setup to cross build rpms to mips/mipsel.
Make sure your rpm sees

%__ar                   %{_target_prefix}-linux-ar
%__as                   %{_target_prefix}-linux-as
%__cc                   %{_target_prefix}-linux-gcc
%__cxx                  %{_target_prefix}-linux-c++
%__ld                   %{_target_prefix}-linux-ld
%__nm                   %{_target_prefix}-linux-nm
%__objcopy              %{_target_prefix}-linux-objcopy
%__objdump              %{_target_prefix}-linux-objdump
%__ranlib               %{_target_prefix}-linux-ranlib
%__strip                %{_target_prefix}-linux-strip

and do

# rpm --target=mips --define '_target_prefix mips'

or

# rpm --target=mipsel --define '_target_prefix mipsel'

BTW, you alao need to rebuild binutils with

# rpm --define 'ENABLE_ALL_TARGETS 1' -ta binutils-2.11.90.0.23.tar.gz

It's not yet available for MIPS (later this week), but MontaVista Journeyman
contains the patches to cross-compile Perl.  It's not pretty, though.

That is a reason why I didn't bother with cross-compile Perl :-). The
next thing on my todo list is to cross compile XFree86 :-(.

If you can get cross-compiling full XFree86, you'll be a hero of all times.
It shouldn't be hard to get it with KDriveArchitecture & TinyX enabled.

I was working on it a while ago, and here are few pointers:
Some tools have to be run natively (i.e. xkbcomp), but also need to
be installed on target. I din't find a rule that does both. I think new
rule is needed.

gcc-3.0 crashes when compiling some parts of Xserver and Xlib,
with very obscure bug. Minimal test case I came up with is
~45(!) lines long. Keith filed report to gcc team on my behalf,
but there seems to be no responce. I do not know if your
gcc has same problem, but someone mentioned similar problem
with 2.9x.y series on this list not so long ago.

Hmm... I can't remember any other interesting things at this moment, but if I
will, I'll follow up...

I am aware of those. I want to delay it as much as I can.

Don't bother with gcc-3.0. I won't use it myself for building X.

recent messages to the XFree86 mailing lists has the recipe to x-compile

Those messages are about compiling using TinyX and KDrive, which
works with only minor modifications. Thing is, it is not what is really needed.

It look like there is a cross dependence, the build of tcsh failed with the
following message:

/var/tmp/rpm-tmp.7250: /usr/bin/perl: No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.7250 (%build)

So tcsh is needed to build perl and perl is needed to build tcsh :-(

It is ok since the tcsh binary has been built. Just install it to
/bin/tcsh and build the perl rpm. You may have to

# rpm --nodeps --force --rebuild perl-xxx.src.rpm

You only have to do those the first time.

Re: Updates on RedHat 7.1/mips

[Seth Mos]

I am having trouble getting the mipsel packages installed using the
installer provided for 7.1.


I have hooked up a second disk to my i386 workstatition that will house
the filesystem for my mipsel box. Once everything is installed I will put
this disk back in my Qube2 for testing. In the worst case scenario I will
need to boot with the 2.0 kernel that came with the cube.

I have the original disk for the Qube2 so it isn't a big problem if it
takes 50 attempts. I have a lot of patience ;-)

Am I correct to assume that I need to use the install.i386.hd on my
workstation to install the mipsel packages on the second harddrive (hdd in
my case)

I have tried this approach using both the Makefile approach and by running
the install.i386.hd script.

Traceback (innermost, last):
  File "./findrpm", line 5, in ?
    import rpm
ImportError: No module named rpm

Does this ring any bells?
The mipsel packages are located in the RPMS directory which is in the same
directory as the installer and I edited the Makefile and changed ROOT and
REDHAT-ROOT

I wonder if anyone can provide a basic root tarbal which I can use to set
up the basics after which i can start adding stuff.

If I get it into a decent state I will probably make a dump of the fs so
other people with a Qube (1 or 2) can easily clone it.

I was working to use a 2.4 kernel on a standard Qube but
that was a big problem since 2.4 does not compile with the compiler that
came with it and the glibc did not have large file support.

A fs that I would like to put on the Qube is XFS which I already use on my
own i386 home machines and production machines at work.
Since XFS is also tested on mip64 Irix (IIRC) ai64 PPC ai32 and alpha
under linux I expect that it will probably more work but it is more
resilient and faster recovering after crashes.

So if anyone can give advice on installing using the toolkit or provide a
bootable dump image or root tarbal I would be most grateful.
The qube2 comes with a boot loader that understands ext2 and loads the
linux kernel it finds on the system it will probably make it easier to
boot afterwards.

Cheers
Seth

No. It should be install.mipsel.nfs. install.mipsel.hd is for the
native mipsel machine install.

You need to install the rpm-python rpm.

Sure.

install.mipsel.nfs is used to create a NFS root tree for mipsel. If
you tar it up, you get what you are asking for.

Thank you, it worked :-)

And again, thank you.

Will do once it works.
Everythinhg seems to be installed like it should and I copied the 2.0.34 
cobalt kernel to /boot on the Qube2. I have enabled the serial console of 
the Qube2 and see the firmware scroll along.

BOOTLOADER ramcode: selected partition /dev/hda1
Decompressing done
Executing bootloader kernel...
Jump_to_Real_Kernel: disk error, trying BFD again.
BOOTLOADER ramcode: selected partition /dev/hdc1

etc.. Qubes don't have the second IDE controller so this is nonsense ;-)
Does anybody know what's missing? Do I need to format the ext2 root fs in a 
special way? Do I need to pass on other bootoptions and if so. How do I get 
to a command line prompt of the firmware?
I see that the NetBSD people did that to make it boot another kernel.

I thought that the firmware from the Qubes just boot the vmlinux.gz image 
that it finds in the /boot directory on hda1?

Any help appreciated.

Cheers

Illegal Instruction

[Nandakumar NarayanaSwamy]

Hi All,

My kernel is crashing when i try to insmod a driver. I am getting 
the following error messages


insmod:19] Illegal instruction 000003e8 at c0015cf4 ra=c0088dd4
[[insmod:19] Illegal instruction c000d9d4 at c000b6a4 
ra=c000b69c

When i tried to locate this happens when i call rt_usleep 
function.
This is the piece of code where i call nano2count.

void mysleep (uint32 micro_sec)
{
    RTIME delay;

    delay = nano2count (micro_sec * 1000LL);
    rt_sleep (delay);
}

I am exactly getting the insmod error when there is a call to 
nano2count.
Note : RTIME is of type "long long".
The CPU i am using is IDT RC32334.

Can any body help me to solve this?

with best regards,
Nanda
