RTLinux and Suse can they work together

["David Broadbent" <worldrobots@hotmail.com>]

Greetings  all,
sorry for a somewhat long winded message I'll put questions first, history 
of why i would like to know 2nd, a brief extract about RTLinux from there 
web site for reference purposes, and finally my hardware platform 
description. If you are into data acq & contol do look at the info on this 
board family, it had linux drivers and is guarenteed to do all i/o 
Simultaneous due to the onboard DSP engine.

WHAT I WOULD LIKE TO ASK IS :-
==============================

q1. is Suse Linux product ( 6.1 or 6.4) comparable with RTLinux ?

q2. or is there a RT version of SuSE Linux ?

q3. or it appears that RTLinux is "merged" with Linux 2.2 kernels could it 
use SuSE kernel instead ? Has anybody done this task ?

Q4. any other comments in relation to real time operation would be much 
appreciated .. especially as i would like to stay with Suse product if 
possible

I hope you can help in this matter

HISTORY.....

In January 2000 I loaded SuSE Linux 6.1 on to a new computer I am setting 
up.

I have just  purchased ( 7th June 200) a Multi-function Data subsystem pcb ( 
see http://www.powerdaq.com/ ) for this computer to perform initially a 
specific ' Closed loop" test on some remote ( 1 metre distant of computer) 
phase measuring hardware.

  The Data Acquisition pcb supplier suggested I should use RTLinux and I 
have been looking at their website

http://www.rtlinux.org/rtlinux.new/index.html

and i quote from their faq
=================================================================
Q: What's the basic idea of RTLinux?

   A: RTLinux is a small, deterministic, real-time operating system that is 
somewhat like a single POSIX process sitting on a bare machine. Hard 
realtime applications are threads and signal handlers in this process. Linux 
runs as the lowest priority thread of the RTLinux kernel and it is made 
always pre-emptible. The RTLinux programming model is that anything that has 
strict timing requirements should be written as a thread or signal handler 
(interrupt handler) and whatever does not need hard realtime should go into 
Linux. This allows us to ep the RT side small, deterministic and as fast as 
the hardware will permit, while still drawing on Linux for sophisticated 
services and  applications.

The basic mechanism that makes RTLinux work is protected under U.S.
Patent 5,995,745 and is freely licensed to RTLinux users for commercial and 
non-commercial purposes ------ etc.
