Hi,
It looks like something changed in the way to find all the bits and
pieces to patch/build the Denx PPC/ipipe/xenomai combo.
Looking here:
http://git.xenomai.org/?p=xenomai-head.git;a=blob;f=ksrc/arch/powerpc/patches/README;h=010a86ecabce19212a8eaa1e0aaf8dc43b4805f3;hb=master
I read:
>>>
from Linux v2.6.22 to v2.6.32
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
>From git://www.denx.de/git/linux-2.6-denx.git
Patch release Commit #
---------------------------- ----------------------------------------
2.6.22-DENX-*/powerpc 3e833ffb06a4ce14f2680a0afe9abd5342188e17
...
2.6.32.3-DENX-*/powerpc 224f363857f05ab44dab3441112965f0a7966788
from Linux v2.6.20 to v2.6.21
from Linux v2.6.33 onward
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
>From ftp://ftp.free.fr/mirrors/ftp.kernel.org/linux/kernel/v2.6/
All patches are based on mainline kernel releases.
<<<
Does this mean, that the patches are not anymore against the DENX git
repository, but against mainline?
What I would do up to now is to find in the denx git repository the
corresponding commit or similar;)
There seems to be an 2.6.33 ipipe patch:
http://git.xenomai.org/?p=xenomai-head.git;a=blob;f=ksrc/arch/powerpc/patches/adeos-ipipe-2.6.33-powerpc-2.9-00.patch;h=7b84ba91606e7873227ef70d99aa077362248f4a;hb=master
So I would apply this on:
http://git.denx.de/?p=linux-2.6-denx.git;a=shortlog;h=refs/heads/DENX-v2.6.33-stable
Or should I use
http://git.denx.de/?p=ipipe-2.6.git;a=summary
Or something completely different?
With
http://git.xenomai.org/?p=xenomai-head.git;a=summary
I'm confused what's the recommended way to get the latest and greatest
ipipe/kernel/xenomai combination based on a DENX ppc kernel tree.
Please advise.
Regards,
Robert

This is not a contradiction - our linux-2.6-denx repository is based
on the kernel.org tree and fully includes it.
The "kernel.org" branch in our "linux-2.6-denx" repository is
directly tracking the mainline kernel tree.

Just refer to the git commit ID, and you will find it happens to be
there.

Of course not. You do not use the web interface to actually work with
git. And "v2.6.33" in mainline is something different than our
DENX-v2.6.33-stable branch (which BTW is a branch, i. e. not a
specific commit).
> Or something completely different?
If you want to get "v2.6.33", you check out this version: You would
initially run "git clone" to clone either the kernel.org mainline
repository, or, if you like, our "linux-2.6-denx" repository. Then
you would run the command
git checkout v2.6.33
to get the exact state of sources these patches were created against.

See above: "git clone" followed by "git checkout" - as usual.

Perhaps Robert's concern is whether the IPIPE patch will cleanly
apply to the DENX branch, since DENX has additional drivers,
changes, etc. relative to the mainline. And I guess the answer
is "it depends".

Correct. It depends.

Thanks Wolfgang,
I did
git clone git://git.denx.de/linux-2.6-denx.git
followed by

And used adeos-ipipe-2.6.33-powerpc-2.9-00.patch
plus git clone git://xenomai.org/xenomai-head
Everything builds happily for a kilauea board, but...
./cyclictest -t3
Segmentation fault
I'll open another thread here for this problem.
This seems to be broken for quite some time now.
Regards,
Robert

Ok. Could you run this program under gdb to see at least where the
segmentation fault happens? But first, could you show us the result of
the "ulimit -s" command before running cyclictest?
