[Xenomai-core] Xenomai port on CRIS architecture

[OB]

Hello, 

I could not find any reference to a port of Xenomai (Adeos) on the
Etrax/CRIS architecture. 
There are reference to an RTAI port, without any activity at the moment.

If nobody is working on it, I'm ok to try !

My reference plateform is a FOX board, which include several GPIO and
even a parallel port-like interface.

Also, please let me know if anybody has any interest in this projet
(beside me!)

Supporting an architecture is not "just" about writing a patch once, it
is also takes someone to keep an eye on it so that it evolves with the
projects, Linux kernel and RT-extension. The absolute minimum
requirement are active users/testers reporting any brokenness, even
better a maintainer providing fixes/updates. Obviously, this didn't work
for the RTAI port.

You are welcome!

Maybe there are not already dozens of people waiting for CRIS support,
but once we have a clean and working port, I guess there will be people
showing up. Doing a bit advertising later in CRIS-related forums or to
board vendors can accelerate this even further.

I for one would be interested in seeing something, even of it was only some 
latency test figures.. The FOX board is relatively inexpensive, so if it 
could deliver reasonable latency figures, it would surely be another 
contender for embedded control.
