[Xenomai-help] Xenomai patches

[Leopold Palomo-Avellaneda]

Hi,

I'm having a trouble installing xenomai in a debian machines. Actually the 
official debian package is not useful. You cannot use it because there's no 
kernel package that could be patched.

Anyway, I would like to ask about if, for example, a patch against a 2.6.30 
could be used against 2.6.30.4 for example or reverse. I don't understand why 
this four numbers instead of the classical 3. Or, how can I modify it to use 
it.

Regards,

Leo

The debian packages are not maintained by the Xenomai project. So, if
you are having problems with these, please contact Roland Stigge. You
will probably find his e-mail address in /usr/share/doc/*xenomai, but
the e-mail address he used the last time he posted on the xenomai
mailing lists is:
stigge@domain.hid

Usually, I-pipe patches are for the base release, but work with later
releases. When it happens that there is a conflict, and we find out
about it, we release another I-pipe patch e.g for 2.6.30.4. In that
case, you need to use the I-pipe patch for 2.6.30.4 for 2.6.30.4 and later.

These are releases from the stable branch:

yes, I know. Sorry for the noise. My fingers were faster than my brain. This 
comment have to go as bug to the package, not to the xenomai list.

well, as I understand if you release a I-pipe patch for a kernel 2.x.y 
it "should work" for all the releases 2.x.y.z (z>0) in "theory", but if 
there's a problem, then you release a patch for 2.x.y.z and this patch then 
works for 2.x.y.z (where z is the version where the conflict occurred, no?

But this patch also works with the previous versions (0 < z < ...) ?

Ok,

thanks for the link. Well explained.

Try to modify the line starting with KVERSION=... in the file
/usr/src/kernel-patches/$ARCH/apply/xenomai
Replace the 4 digit version numbers with 3 digits.

However, if suggest to download the kernel source from kernel.org, this will work
without changing the above mentioned file.

Im using Debian Lenny and the following is working for me:
(replace the version numbers...)

First: build the xenomai deb packages:
--------------------------------------

1) install needed packages as root:
# apt-get install debhelper devscripts dh-kpatches findutils

2) create a new directory:
~$ mkdir -p src/xenomai && cd src/xenomai

3) download xenomai:
~/src/xenomai$ wget http://download.gna.org/xenomai/stable/xenomai-2.4.7.tar.bz2

4) repack the archive (*tar.bz2 -> *orig.tar.gz):
~/src/xenomai$ bzcat xenomai-2.4.7.tar.bz2 | gzip > xenomai_2.4.7.orig.tar.gz && rm xenomai-2.4.7.tar.bz2

5) extract the archive:
~/src/xenomai$ tar -zxf xenomai_2.4.7.orig.tar.gz

6) change dir:
~/src/xenomai$ cd xenomai-2.4.7/

7) update debian/changelog:
~/src/xenomai/xenomai-2.4.7$ debchange -v 2.4.7-0 Release 2.4.7

8) build:
~/src/xenomai/xenomai-2.4.7$ debuild

9) as root: install the deb's:
/..../src/xenomai# dpkg -i *.deb


Second: download, patch and build the kernel:
---------------------------------------------

1) install needed packages:
# apt-get install kernel-package libncurses-dev fakeroot zlib1g-dev

2) create a new directory:
~$ mkdir -p src/linux && cd src/linux

3) download kernel source:
~/src/linux$ wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.28.7.tar.bz2

4) extract it:
~/src/linux$ tar -jxf linux-2.6.28.7.tar.bz2

5) enter directory:
~/src/linux$ cd linux-2.6.28.7/

6) patch the kernel with xenomai:
~/src/linux/linux-2.6.28.7$ /usr/src/kernel-patches/i386/apply/xenomai

7) configure the kernel:
[optional] copy a kernel config to .config and run "make oldconfig" [/optional]
~/src/linux/linux-2.6.28.7$ make menuconfig

8) compile the kernel with make-kpkg:
~/src/linux/linux-2.6.28.7$ fakeroot make-kpkg --initrd --append-to-version -xenomai-2.4.7 --revision 1.0 binary-arch

if you have a multicore box, use CONCURRENCY_LEVEL= to speed up the build:
~/src/linux/linux-2.6.28.7$ CONCURRENCY_LEVEL=2 fakeroot make-kpkg --initrd --append-to-version -xenomai-2.4.7 --revision 1.0
binary-arch

9) as root: install the deb's:
/..../src/linux# dpkg -i *.deb


thats all folks...

Hi Stefan,

first of all thanks for the guide. I knew more or less all the steps, but you 
have helped me a lot.

Ok, good to know. This is in same line as Gilles Chanteperdrix mail.

I don't think that this is necessary. At last I didn't need it.

I did it with dch -i . Both are valid.

it builds the tar.orig.gz

you can do it alltogether with:

fakeroot make-kpkg --initrd --added-patches xenomai --config 
menuconfig --append-to-version "-xenomai-2.4.10" -revision 1.0 binary-arch

also, instead of binary-arch, with kernel_image kernel_headers it's ok.

FANTASTIC!!!!

the CONCURRENCY_LEVEL it's great. I didn't know it!!! thanks a lot.

OTOH, the debian package has a bug. I cannot compile xenomai, using the debian 
way on kernels 2.6.28, 2.6.29 and 2.6.30 because the package add something 
that fails with make menuconfig. I should write a bug. Just for information, 
it's not a xenomai upstream related question. ;-)

Thanks for all,

Best regards,

Leo

Please check xenomai-2.4.9.1. It may happen that the bug has been
already solved.

nops, sorry again my fingers were so fast ...

we are talking about the same? I got:

I am not talking about any specific bug. It was just a general advice.
In any case, we are not responsible for the Xenomai packages made by the
Debian team, but if you find bugs in the debian directory which is part
of the Xenomai package, we are interested in fixing them, of course.

well, I have found two things:

1) the debian directory is very similar in both (upstream and debian 
official). The method to create the package is described in the xenomai wiki 
and have been working so well till now (at least in my case). The script or 
the patch applied in the versions of the kernel 2.6.28>= introduces something 
that make fail the make menuconfig step. If you apply the patch with the 
script (scripts/prepare-kernel.sh) the make menuconfig works

2) after the step of preparing the kernel, (with xenomai 2.4.10) when I 
compile the kernel (2.6.30., it fails in:

 CC      arch/x86/xenomai/hal-common.o
arch/x86/xenomai/hal_32.c: In function ‘rthal_latency_above_max’:

Now, I'm compiling 2.6.29 with 2.4.10 ...

Just disable CONFIG_XENO_HW_NMI_DEBUG_LATENCY (it's widely broken in 2.4
for recent kernels).

I diffed the two debian directories 3 weeks ago. There are some changes in
the debian version which are not in the xenomai repository. And there are
some fixes in the xenomai debian directory which are not in the official
debian package.

The official debian version in testing is targeted for Debian 6.0 Squeeze
and as far as i remember there are small changes which will break the build
for Debian 5.0 Lenny. This changes shouldnt get merged IMHO to the xenomai
debian version. I will try to create patches to synchronize the two versions.

The following commit fixed (at least for 2.6.28) the patching of init/Kconfig.
This fix is not in the official debian package, only in the xenomai repository.

debian: fix kernel patch preparation script not to truncate init/Kconfig
