I have some more questions concerning the relation between PAX and the
RT-Patch :
A) Can they work together ?
B) Do you know if it matters which patch is applied first ?
C) Is there any documentation about this subject ?
Thanks

It can be made to work. We have it working together in our distribution.

Not really.
> C) Is there any documentation about this subject ?
None that I know of. I imagine that I'm the only person who has ever
done this.
There are some conflicts (a few are non-trivial, but not excessively
complicated, IIRC). But it's not something insurmountable. You do have
to have a fairly good understanding of kernel code.

Thanks
The answer is very surprising.
I would assume that more than one person would have such an experience.
I am curious regarding the magnitude of work to be done. I am
especially intersted what happens when you have to handle another
Linux version for your distribution.
Is this job done just once (for one specific Linux version) ?
or
You do the job once, and then do the same fixes on the other Linux
version (more or less) ?
or
You have to do the same job all over again in every linux version ?
Is the following discription correct ?
Basically the job is
1) Download kernel
2) apply RT-patch
3) apply PAX patch
4) compile and fix warnings and errors
Thanks
again

Well, the LTSI organization may have done it. That's all I can think
of, though.

Once for a specific Linux version, 3.10.

We will on the next version we release, yes.

Well, there's testing :). But basically yes. Resolving the conflicts
is the biggest deal, really, in the above process. And testing is a lot
bigger than that :).
We integrate a lot of other things, so it's hard to remember the
specific RT/PaX issues.

Thanks
One last question : it the source of this patched kernel open ?
Thanks

No, it's part of our product line. It also has a lot of other patches
integrated for board support and other features.
