Is there a way to place linux on its own core so that it continues to
operate under high realtime loads?
I seem to be able to do this with a xenomai kernel task and user space
task. As a test I created a large load in my kernel task which of course
caused my xenomai user space application to come to a crawl as expected
since they were both on CPU0.
I recompiled my kernel task with T_FPU|T_CPU(2). With the xenomai user
space task on CPU0 and kernel task on CPU2 they operated in parallel so
my xenomai user space task did not come to crawl.
I was hoping linux could run on CPU1 & CPU3 so that keyboard input and
mouse input doesn't stop under heavy loads in a kernel task . However
currently under heavy kernel loading linux basically stops.
I am currently using xenomai 2.5.5.2 w/ Ubuntu 10.04 and testing on an
ATOM D525 which shows up as 4 CPU's (two cores with two hyper threads)
my second test machine is a i5 750 (four cores).

Dear Xenomai Team,
Iam booting from sd card on my target board with ubuntu 10.04 .
Is it possible to port xenomai besides ubuntu 10.04.

No, actually not. It already took us AGES to escape linux 0.99pl12 on an
overclocked 486SX, so I can't really imagine another port right now.
This just drained us for the next ten years.
Any other help we could bring?

If you want Xenomai running on another Linux platform/architecture,
check the information on the net, check the Xenomai code base. If you
want Xenomai to run on bare hardware, this is a DIY task.
PS: please do not reuse completely unrelated posts to ask your
questions. Mailing list users are relying on subjects to follow threads.
