[Qemu-devel] ANN: DetaolB v0.4 is released

[Christian MICHON]

DetaolB aimed to be a "much-less-than-a-floppy" x86 linux live distro.
Now, it's evolving more into "a-la-slax" type of distro.

DetaolB v0.4 has been released 29th,June 2007 on sf.net
=> http://sourceforge.net/project/showfiles.php?group_id=140321&package_id=155481&release_id=519786

Mailing list: detaolb-devel@lists.sourceforge.net

- vesafb-tng included (default boot is 800x600x24bpp)
- included some X11 functionality: log in as root, then "xinit"
- included ext2fs utilities: you can now work in qemu/vmplayer
- self sufficient to compile itself and linux-2.6.21

As the number of Sparc32 distributions keeps approaching zero, could
you consider porting DetaolB to non-x86 CPUs?

The reason why distributions drop sparc32 is the unmaintained kernel.
Nobody stepped up for Linux kernel maintenance in the last years.
Debian managed to keep up a sort-of working kernel for the last
release, the people who put their time into it are disinclined to
repeat this exercise.

good point. I'm not a kernel maintainer, I'm just a distro maker.

there might be a arm port (I'll need to figure out the framebuffer part though).

the original target of detaolb is to have a quick x86 development environment
that can boot/run quickly in qemu.

But there is a difference in maintaining a kernel suitable for high
quality distribution with over 18733 packages working in different
real hardware, versus a test/evaluation distribution with <30 packages
running on Qemu. I'd see that as an "enhanced qemu-tests.tar.gz".

ok, I documented myself, and I'll try on sparc32.
any hint on patches, config files for the kernel ?

will uclibc work well enough on sparc32 ?

I used the attached config for sparc-test kernel build, with one patch
for TCX that shouldn't be necessary for newer kernels.

I have no first hand experience. Busybox works fine.

I noticed spurious fast keyboard repeats. Like I must be

I plan to build uclibc and the rest natively from aurora

Hi,

You may want to look at crosskit.sourceforge.net (a crosstool/buildroot-like
project that I have recently started and that you can find on sourceforge).
Following your e-mails, I have added sparc support. The toolchain builds
fine but busybox fails to link (sched_getaffinity and sched_setaffinity
undefined). If I manage to pass this issue, I will then try to build a
kernel for sparc for testing with qemu-sparc. I will also add glibc support
(crosskit aims at providing scripts for building packages against either
uclibc or glibc).

I haven't looked at detaoib yet but it was surely created before crosskit
and may therefore be a safer bet.

Cedric Hombourger

DetaolB aims to be a native solution, not a cross compiling tool.
I've to get to the point where a native sparc32 toolchain will be usable
in detaolb-sparc32...

Is there a special reason to use Aurora? I thought it was an

Debian was the only maintained Sparc distribution I could recently

when trying to boot aurora, it stops and complains about

I already gave a hda disk. is it a problem of size or a

what command line did you use when you reported a

qemu-system-sparc -boot d -hda aurora-1.0.img -cdrom  aurora-1.0-sparc-disc1.iso

I tested Aurora 1.0 and 2.0, 2.1 can't read from cdrom. I tried 2.98
only briefly and never 2.99.

I did this too. maybe aurora is not a good idea then.

maybe simply a stage3 sparc from gentoo would do ?

ok,

I found this file (google for it): stage3-sparc-2006.0.tar.bz2

I put it into a vmdk image file, preformatted in ext2 fs.
I touched up a few files and used the sparc kernel and
binaries from the qemu-windows page.

I've now a native compiler for sparc32. I managed some
stuff with it already. If the kernel patches I've works with
this compiler, porting DetaolB to sparc32 should be fine.
I'll just take some times (native compilation in qemu).

Many of you will say: why not cross-compiling ? It's
hard to setup. Actually, the paper from Rob at OLS
should help me a lot when he'll release it. ;-)

What's the difference between deltaolb and Firmware Linux, anyway?  I'm still 
curious about this.

Firmware Linux currently builds both working cross-compilers and minimal 
native build environments you can boot into for qemu.  It does this for x86, 
x86-64, armv4-soft and armv5-vfp (both OABI, I'll probably move the v5 to 
EABI when I get around to it), and both endiannesses of mips.  It also does 
sparc32 (although there's a bug, probably in uClibc, which I have yet to 
track down that screws up console initialization, so init=/bin/hello 
prints "hello world" for both static and dynamic, but init=/bin/sh hangs.)  
And I've got a working powerpc cross compiler that builds a root filesystem 
but have yet to build a kernel qemu can boot.

The theory I've been going on is that once you've got a minimal native build 
environment, you boot into it and build the rest of what you need in there 
for your target platform.  The next release will come with a setup script to 
let you run Firmware Linux under itself.  (And thus cross compile from arm to 
mips or equally silly things.)  A friend of mine built 60 gentoo packages 
under the thing before he got bored, although he was using an x86 chroot 
rather than qemu.  I'm trying to get _that_ script into the next release as 
well, and then tackle Ubuntu starting from 
http://www.quietearth.us/articles/2006/08/16/Building-deb-package-from-source

Plus the distcc cross compile thing.  I've now got networking working on arm 
(qemu's arm PCI controller can't do PIO yet, so I needed to switch from ne2k 
to rtl8139 setup for mmio, then networking worked fine) so setting up distcc 
is mostly a matter of making a cross compiler that does C++ as well.  Not 
sure if it should be the bootstrap one or if I should build a second copy...

Oh, by the way, the Fedora for Arm project is also building natively on arm, 
but they got some fast ARM hardware and stuck lots of DRAM and hard drive 
space onto it rather than using QEMU.

a few differences, quite minor actually (that's why I said in the past we
shared many common goals :-) )...

I actually started this in 2002, but then hit many bugs in uclibc. In the end,
I actually used a trimmed LFS approach, using zisofs. My bootable env
then was ~45Mb. At that time, buildroot was also starting... I lacked of
time to work on it.

The biggest difference today is that your firmware is based on automation
or Makefiles, whereas I still use a LFS type of approach. I first build a
static minimal toolchain with a static busybox: all native, no cross
compilation. Then I chroot in it, compile uclibc, busybox, the toolchain.
The rest is obvious, but quite manual. I really should do Makefiles...

The other difference is that I base detaolb on aufs/squashfs (I do not
think you passed that stage yet, if I recall not all the archs you're
targetting can take this). That's today's improvement over the stuff
I did in 2002 using zifofs.

in 2003/2004, I also worked on porting linux to an Ipaq h2215. I actually then
used buildroot arm precompiled, and managed to chroot in it using nfs over
usb. quite cool, and the speed was better than qemu today. It was just a
400Mhz Xscale.

I'm still interested in your cross compiling tutorial. I believe we all are :)

If I start putting too many archs in the picture, I believe DetaolB will be
redundant with Firmware. This is not intended. Originally I wanted to
share the portable x86 env I carry on my usb key. Some of you asked
for a sparc32 port. I'll complete this one at least (I'm progressing quite
fast on it).

Firmware Linux has a sparc target.

http://landley.net/code/firmware

Go "./build.sh sparc" and then look at run-sparc.sh in the build directory.

There's a bug I haven't bothered to track down (possibly in uClibc) that 
prevents the console from initializing properly, but if you boot with 
init=/tools/bin/hello-dynamic you get a "hello world" message.  (I haven't 
tracked down why the shell hangs yet.)

Just FYI, Firmware Linux builds for sparc and has for months now.

http://landley.net/code/firmware

Go "./build.sh sparc", and wait a bit.  It even generates a run-sparc.sh in 
the build directory that'll invoke qemu against the kernel and ext2 image it 
generated.

That creates a sparc cross compiler, uses it to build a root filesystem 
containing a native toolchain for sparc, and packages it into an ext2 image.  
Over on arm I've built binutils and gcc natively inside the emulator.

The sparc platform has a problem that if I boot with init as a "hello world" 
program everything behaves as expected (there are two in the image for 
testing purposes, /tools/bin/hello-dynamic and /tools/bin/hello-static).  But 
if you boot with init=/tools/bin/bash it hangs.  And so do the busybox 
shells.

I think it's a uClibc bug on sparc, but haven't made time to track it down.  
Either that or the kernel needs something _weird_ for console initialization.  
(The cross-compiler and kernel seem to be working fine...)

You can try it out yourself by downloading all the *sparc* files from 
http://landley.net/code/firmware/downloads/images and then running:

qemu-system-sparc -nographic -no-reboot -hda image-sparc.ext2 -kernel \
  zImage-sparc -append 'rw init=/tools/bin/hello-dynamic panic=1 \
  PATH=/tools/bin root=/dev/sda console=ttyS0'

That prints "Hello world!", panics, and exits.

./run-sparc.sh does the exact same command line with "init=/tools/bin/sh" 
(bash 2.05b), which hangs.  Note that init=/tools/bin/ash (busybox ash) does 
the same thing.  Haven't debugged beyond that yet...

I think there is a problem with the dynamic loader, I get a bus error
when running the programs on real Sparc.

If I try to run the dynamic loader, it reports on real HW as well as on Qemu:
Standalone execution is not supported yet

Huh.  That's odd because hello-dynamic is using the dynamic loader.  (That's 
why there's a hello-dynamic and a hello-static.)

It's entirely possibly that qemu and real sparc hardware are behaving 
differently, but I'm not seeing this bus error under qemu.  (I haven't got 
real sparc hardware, so I can only debug against qemu...)

> If I try to run the dynamic loader, it reports on real HW as well as on

The ability to run the dynamic loader as an executable and the ability to use 
it as a dynamic loader are two completely unrelated things on a modern Linux 
system.  The kernel doesn't _exec_ the library loader, it calls into it as a 
shared library.

In fact, under 2.4 if you ever mount any partitions with "noexec" you also 
need to remove the executable bit from the shared library loader, because 
otherwise you can just run the library loader and feed it any program to run 
and it'll do it for you.  (The library loader doesn't care about the noexec 
mount flag.)

Of course between 2.4 and 2.6 they added an extra check to the kernel so it 
refused to exec a program if the shared library loader that program refers to 
didn't have the executable bit set, for "security" reasons.  (And the glibc 
guys made ld-linux.so start checking the executable bit on libraries too.)  
This of course means that the old trick of removing the executable bit 
doesn't _work_ anymore, so mounting stuff "noexec" is essentially 
meaningless.  Oh well, it already was if you had something like "perl" on the 
system.  Or a command shell that could launch a shell script. :)

Note also that this is why uClibc includes its own "ldd", because the glibc 
one is just a wrapper that attempts to execute ld-linux.so with some 
debugging arguments to dump the library names.  So the glibc ldd doesn't work 
on uClibc binaries, because they're not linked against ld-linux.so.  The 
uClibc one works like readelf instead, and should work on anything.

But anyway, the ability to run a library loader as a command, and its ability 
to function _as_ a library loader, are totally unrelated.  Different entry 
points.

This talks about the issue in passing:

I hit this today. I'll need this patch then, since I did not see the problem
on i686. Thanks!

Right. Debugging the problem I found out that in Qemu, 64-bit loads
and stores to unaligned addresses do not trigger any traps as they
should. I'll commit a fix soon. The problem is in uClibc ldso, there
is this kind of store.

Running the program on qemu-sparc reveals another problem, probably
because of these definitions in ldso/ldso/sparc/dl-sysdep.h:
/* 4096 bytes alignment */
/* ...but 8192 is required for mmap() on sparc64 kernel */
#define PAGE_ALIGN 0xffffe000
#define ADDR_ALIGN 0x1fff
#define OFFS_ALIGN 0x7fffe000

On Sparc32 the correct page alignment is still 4096. Because of these
definitions, some code apparently tries to clear a 8k page, but only
4k of memory is mapped.

I just managed a compilation of bash-3.2 using ncurses-5.6 and
uClibc-0.9.29 inside a qemu-system-sparc (native compilation,
no cross compilation).

"ldd ./bash" points naturally to libdl.so.0, libc.so.0, ld-uClibc.so.0

./bash
Segmentation fault

I do not have gdb compiled yet... I'll check soon with busybox
ash, since I recompiled uClibc with the sched_affinity patch.

busybox-1.6.0 does segfault here too. I had to remove taskset
as apparently the sched_affinity patch did not fix the linking
step.

is there a repository of sparc/uclibc patches somewhere ?
Blue mentionned he'll have a fix for uclibc ldso. I'll try it using
this dev environment as soon as it'll be out.

When you get that kind of segmentation fault, see if "hello world" segfaults 
too.  (In general, when building with a new toolchain, new C library, new 
kernel, new root filesystem packaging method, or a new system in general, if 
anything goes wrong back up a few steps and make sure "hello world" works 
before trying to debug anything fancier.)

I'll leave that to you.  I can commit the patches to the uClibc repository if 
you can get them to me and confirm they work for you.  (And get them added to 
the 0.9.29.1 patch list.)

Hmmm...  It's possible that "hello world" is working but nothing larger is 
just because it uses such small amounts of memory nothing ever crosses a page 
boundary, or gets aligned properly by accident...

I look forward to a fix.  It would be nice to add sparc to the "actually 
works" list. :)

I was not clear then. I've binutils already compiled versus uClibc for sparc,
and it works. Some of those binaries from binutils are bigger than the
expected size of final uclibc dynamic busybox.

of course, as soon as I got uclibc compiled, hello world comes first to
my mind, and it was working.

that's 2 persons looking forward to it. ;-)

today's results:
- uclibc ok (minus the segfaults coming from it)
- conf from busybox segfaults
- bash segfaults
- busybox segfaults
- gcc does not build without bash (I'll replace with ash tomorrow)
- binutils ok
- ncurses ok (I need to look at uclibc' conf now)
- make ok
- bzip2 ok
- coreutils ok
- findutils ok

Blue swirl, please note that the porting of DetaolB to sparc32 will
take more time than scheduled, once the segfault issues are
covered. I'd like to spend some time testing firmware and cross
compilation :)
