[Xenomai] Xenomai on v3.14

[Xenomai] Xenomai on v3.14

[Brian Morel]

I want to start working on Xenomai & I-pipe on kernel 3.14 for arm (beagle
bone black).  I was hoping for a little advise on which git repositories to
use for both Xenomai & I-Pipe.  It looks like I would need the I-Pipe patch
from either the main I-Pipe repo. or one of the named repos.  Can I use
this with the Xenomai 2.6.3 for the user land side of things?

Thanks,

Brian Morel

ipipe-3.14 has just landed in git://git.xenomai.org/ipipe.git, with the 
latest ARM bits merged. The I-pipe support for ARM usually brews in this 
tree: git://git.xenomai.org/ipipe-gch.git, then gets merged in our 
mainline tree as mentioned earlier.

Yes, all Xenomai 2.6.x releases are ABI compatible. You would have to to 
pull the code from our maintenance branch in xenomai-2.6.git (master), 
only to build the current Xenomai kernel bits against 3.14.

Make sure to disable CONFIG_CONTEXT_TRACKING for now. We are still 
investigating an issue with this feature.

I cloned the ipipe.git repository & checked out ipipe-3.14 .  I tried
running the genpatches.sh script, but it appears that tag v3.14 doesn't
exist in the repository.  I tried the same process for 3.8 & it worked
fine.  I assume this is because the stable tree isn't there, but my git foo
isn't good, so I don't know how to add it.  Any advice would be great.

Thanks, Brian

The latest mainline tags have been pushed to the tree. Please retry.

Note that you can work directly with the ipipe git instead of generating
patches, simply run prepare-kernel.sh from the ipipe git,
prepare-kernel.sh will detect that the kernel already contains the ipipe
bits and will not try and apply an I-pipe patch. This makes testing
changes to the I-pipe kernel a lot easier.

Is this a reasonable patch if one (still) wants to use genpatches.sh?
