[Xenomai] ipipe-4.4.y LTS

[Radu Rendec]

Hi all,

Are there any plans to maintain the ipipe-4.4.y branch and update it to
later versions of kernel 4.4? It would be nice to have, since at this
point kernel 4.4 has the longest projected EOL.

Currently the latest thing that can be merged cleanly on top of
ipipe-core-4.4.71-powerpc-8 is kernel 4.4.73, which is only 2 releases
later than what's already in there.

Thanks,
Radu Rendec

Are there still plans to have a ipipe patch for the CIP kernel?  I
think this was brought up at the last meet up?  Maybe the bigger
question (which is a lot more work) is do we plan on maintaining ipipe
for 4.4, 4.9 and older?

Yes, there are plans to go over 4.4-CIP. So far, I'm only maintaining
based on 4.4-LTS, just tested on x86, pushed to
https://lab.xenomai.org/ipipe-jki.git/log/?h=for-upstream/4.4-update.
Would be happy to receive contributions in form of tests on other
architectures!

That's great news! Thanks for the hard work! I'm targeting powerpc, so I
will probably get back with some test results during the next couple of
weeks.

Looking at the history in Jan's tree, it seems "for-upstream/4.4-update"
is updated quite often. Perhaps it would be a good idea to keep the
ipipe-4.4.y branch in sync or at least advertise Jan's tree on the
Xenomai website. It would be useful for people like me who are interested
in a recent 4.4-LTS version of ipipe.

Thanks,
Radu

Jan as Master mode access to [1], a 4.4 LTS branch may be maintained
directly there.

I can run some tests on ARM boards I have.

ARM-wise, I don't think we would have the resources required to maintain
the I-pipe for more than a single kernel release at a time.
