Anyway, you should read some stuff about linux and realtime. I agree
totally that linux is not a hard-realtime OS, and was never designed
to be such. So I wouldn't deploy it in a few places where QNX is king,
but it's still quite capable.
Here are a couple of links, it's your project, so it's totally your call:
* http://linuxdevices.com/articles/AT8211887833.html this is an
extract of a lkml message (available here
http://lkml.org/lkml/2005/6/7/256) which compares different ways of
achieving realtime in linux.
* http://www.realtimelinuxfoundation.org/ it's basically a bunch of
guys talking about how to make linux realtime, all the time. Check the
"Variants" and "Solutions" sections. There seem to be a few
hard-realtime solutions (unlike Molnar's patch, which gives you
soft-realtime), but they seem quite hard to implement... haven't tried
Now, I'm going back to lurking mode...
