[Xenomai] unable to patch kernel

[Fabian]

Hi,

I am trying to patch a beaglebone black debian arm kernel with the xenomai 3
kernel for dual kernel mode (cobalt).

I used the debian kernel v3.14.39 and the ipipe-core 3.14.39-arm-9.patch,
because this seems to be the newest matching combination. but when i start
the patching it tells me:

prepare-kernel.sh: Unable to patch kernel 3.14.39 with
ipipe-core3.14.39-arm-9.patch

I also tried other kernel and ipipe versions combinations but with the same
result.

I got the debian-kernel from this git: https://github.com/beagleboard/linux.git 

and the xenomai-kernel from here: https://git.xenomai.org/xenomai-3.git


Unfortunately i have not found an instruction how to do this with the new
xenomai version 3, only version 2.6 is described in the net.


Thanks in advance 

Regards

The I-pipe patches are meant for mainline Linux kernels, not for
Linux kernel forks. If you want to apply an I-pipe patch to a Linux
kernel fork, you have to:
- fix the obvious merge conflicts;
- inspect the changes made by the fork which could require further
patching, you can use the following document as a checklist:
http://xenomai.org/2014/09/porting-xenomai-dual-kernel-to-a-new-arm-soc/

If you are interested in using the latest versions, you should have
a look at the I-pipe download area:

That is NOT a debian kernel source.  It looks like a TI kernel source
tree, and certainly the 3.14 branch on it is currently 3.14.51 based.
You didn't say which branch you used.

If you try to manually apply the patch file with patch you might see
where the conflicts are.

This does not change anything. As long as this is not a mainline
Linux kernel source, the I-pipe patches may not apply. And even if
they apply, further work is needed.
