Hi,

My name is Marcin Kuska and I'm new to this list.

Recently i have been trying to compile linux kernel v. 3.0.13 with a
Xenomai real time subsystem extension on ARM versatile express board. I'm
using buildroot-2012.05 to cross-compile the kernel. I patched linux source
tree with adeos-ipipe-3.0.13-arm-1.18-09.patch. The problem is that
buildroot cannot finish compilation and returns following errors:*

and also:

"unsupported ARM machine"

I have read that xenomai only supports integrator/cp board and any other
board like versatile express have to be adapted by myself. So i went to:

http://www.xenomai.org/index.php/I-pipe:ArmPorting

and started adapting and cannot find files like time.c and irq.c. Moreover
I cannot find errors in file gic.c, timer-sp.c and so on (e.g. *gic.c:106:
multiple definition of `__ipipe_mach_ticks_per_jiffy'* i cannot find any
definition of __ipipe_mach_ticks_per_jiffy so even if I would want to
comment one of the definitions to eliminate multipling it's impossible
cause it's not there).

My description of the problem is very blurred i suppose, so if anybody may
be knowing the solution, please ask for more specific details and i will
post them.

Thank you all for reading this message

As said in the following document, time.c and irq.c are just indicative
names, it is the files where the timer and irq controller are
implemented for your platform, you have to find the corresponding files
for your platform.

This version of the I-pipe patch does not support kernels compiled for
multiple platforms. In the kernel configuration, you should only keep
configuration enabled for the only platform/board you use. Then you will
not get multiple definitions.

 Thank you for quick response.

Again I tried to compile it using buildroot but this time I used following
commands:
*
*
*# cd /home/marcin/Documents/buildroot-2012.05/output/build/linux-3.0.13
# make ARCH=arm vexpress_defconfig // i suppose this sets kernel
configuration only for versatile express (ommiting multiple definitions)?
# cd ..
# xenomai/scripts/prepare-kernel.sh --linux=linux-3.0.13
--adeos=adeos-ipipe-3.0.13-arm-1.18-09.patch --arch=arm
# cd /home/marcin/Documents/buildroot-2012.05
# make all
*

and i received this list of errors

make[5]: *** [kernel/xenomai/arch/generic/hal.*

I have no clue what could possibly be wrong with setting. So I decided to
compile my own toolchain as follows:

1. crosstool-ng-1.15.2
2. linux-3.0.13:
*# make ARCH=arm vexpress_defconfig
   [*] use the ARM EABI to compile the kernel
# make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- modules
# make ARCH=arm INSTALL_MOD_PATH=/home/marcin/Documents/arm/target
modules_install*
3. busybox-1.20.0
4. ramdisk:
*# cd /home/marcin/Documents/arm/target
# find . | sudo cpio -o -H newc > /home/marcin/Documents/arm/rootfs.cpio*
5. Kernel:
*# cd linux-3.0.15
**# ../xenomai/scripts/prepare-kernel.sh --linux=linux-3.0.13
--adeos=adeos-ipipe-3.0.13-arm-1.18-09.patch --arch=arm
# make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- zImage*

and the result is

*  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
make[1]: `include/generated/mach-types.h' is up to date.
  CALL    scripts/checksyscalls.sh

You should run make vexpress_defoncig after the prepare-kernel.sh step.

I do not think vexpress_defconfig compiles for one board only, as the
versatile board may hold several processor. Anyway, it is easy to check:
just run make menuconfig/xconfig/whateverconfigyoulike yourself, and
check what boards are enabled in the config.

Hi again,

I'm still stuck in compiling Xenomai 2.6.0 with linux 3.0.13 and I'm still
receiving mulitple definitions. Lately i run the compiling process with " |
grep __ipipe" option to see the warnings at the begining of the compilation
and i got this:

*$ make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnueabi- zImage | grep
__ipipe

make: *** [vmlinux.o] Error 1*

In the listing above it's seen that mostly smp_twd.c and smp_twd.h is the
problem with multiple definitions but i don't know which option i should
uncheck to avoid these definitions - any ideas?
I'm pretty sure that my configs are set to one processor only 'cause in
buildroot menuconfig i chose cortex-a9 as "Target Architecture Variant".

regards,
Marcin

The problem is not the configuration of buildroot, the problem is the
configuration of the Linux kernel. What you should do is only keep one
SOC enabled. If your processor is based on a cortex a9, look at what is
done for omap4, since the omap4 is currently the only in-tree supported
cortex a9.

For instance, the fact that you are compiling both
arch/arm/common/timer-sp.c and smp_twd.c will lead to a conflict the way
timer-sp.c is currently made. omap4 has the same problem since for
instance arch/arm/mach-omap2/timer.c is compiled both in the omap3 and
the omap4 case. So, just look at how it is done, and do it the same way.

Another simpler solution is to start from the ipipe core-3.2 branch,
which supports being built for several SOCs. However, it will require
upgrading to xenomai 2.6 branch head.

Ok I checked the arch/arm/common/timer-sp.c (i assume this file implements
the timer for vexpress) and all the__ipipe_mach_timerint;
__ipipe_mach_timerstolen; and so on, are there and there is nothing to be
done there. I don't know if i understand you right. Which part should I do
the same as with omap4?


About that simpler solution using ipipe core-3.2 branch. There is no ipipe
core-3.2 at the http://download.gna.org/adeos/patches/v3.x/arm/ site or am
I looking for wrong site?

thank you in advance!

The problem is that if you are compiling with CONFIG_SMP for a cortex
a9, there is also an __ipipe_mach_timerint, __ipipe_mach_timerstolen,
etc... in the generic code for cortex a9. So, you get multiple definitions.

omap4 has exactly the same problem, because it compiles some code which
is common with omap3, already modified for CONFIG_IPIPE.

So what you have to do is solve the multiple definitions for vexpress
the way they are solved for the omap4/omap3.

Yes, I am talking about a branch in the adeos ipipe git repository. The
patch is not released yet. But anyway, for what you have to do, working
with git is much simpler than working with patches.

Ok thank you for helping me out! You've been very helpfull.

Just for anyone trying to do the same in future:

I used two of git projects from http://git.xenomai.org/ipipe-gch.git/

   - ipipe-gch.git (linux kernel)
   - xenomai-2.6.git (the file HAVE TO be named xenomai-2.6 as buildroot
   will be looking for that folder and if he denies to find it in
   'output/build' it will start downloading the common xenomai from xenomai
   site and we don't want that)


In buildroot:

   - Kernel->Kernel version (Custom tarball) and specify the URL of a
   tarball (ipipe-gch linux kernel)
   - Linux Kernel Extensions -> UNCHECK Adeos/Xenomai Real-time patch

then build the kernel and that's all.

For me it worked.

Many thanks to Gilles!

So, you can run the latency test with this kernel for instance? Looks to
me like you are building a kernel without xenomai support...

Ahh ok my mistake. I applied the adeos-3.0.13-arm-1.18-09.patch to kernel
by myself that is why i uncheck xenomai kernel extension (but not "Package
Selection for the target->Real-Time"! That one have to remain checked!) in
buildroot setup. Anyway it works and xeno-test works fine also ;)
For now I don't want to change anything as long as everything is ok since I
have to carry on with the project but later on, I will find out the exact
way how did I manage to do this (compile xenomai on versatile express
machine).

It would be interesting if you could post the patch for vexpress, so
that we can include it in future ipipe patches.

All I did was applying standard adeos-3.0.13-arm-1.18-09.patch to kernel
ipipe core-3.2 from your repository and used xenomai upgraded to head
branch as you suggested. All done in buildroot-2012.05 using buildroot's
toolchain. Unfortunately I did not manage to compile it under buildroot
environment with an external toolchain such as crosstool-ng or
CodeSourcery. The reason why I'm trying to compile the linuxXenomaiOnBoard
kernel with an external toolchain is that any application (even hello
world) cross-compiled with e.g. crosstool-ng cannot be run on linux with
Xenomai on board cross-compiled with a buildroot toolchain (the working
one).

So again I tried cross-compile linux with xenomai with a crosstool-ng and
at first hand xenomai works fine cause i received this in dmesg:
*
*
*I-pipe: head domain Xenomai registered.*
*Xenomai: hal/arm started.*
*Xenomai: scheduling class idle registered.*
*Xenomai: scheduling class rt registered.*
*Xenomai: real-time nucleus v2.6.0 (Movin' On) loaded.*
*Xenomai: debug mode enabled.*
*Xenomai: starting native API services.*
*Xenomai: starting POSIX services.*
*Xenomai: starting RTDM services.*

but, latency test doesn't work. Not even xeno-test. Is there in the linux
kernel config any option which enables those?


Thanks and regards

No, you have to either use adeos-3.0.13 patch with a 3.0 kernel, or use
the ipipe core-3.2 patch with no further patch. You can not mix the two.

So what you mean is, run prepare-kernel.sh without option
--adeos=path/to/adeos/patch?

You can pass whatever you like to --adeos, right, even not pass it at
all. prepare-kernel should not even try to apply an adeos patch.

It means you have to follow the I-pipe porting guide to add what is
missing to support your board/SOC combination.
