The vanilla Linux kernel can and is already being used in RT environments. A dual processor box when configured properly can provide a very deterministic env for a properly written RT application. The trick is to realize that the 'box' must be dedicated to that application and that application alone. With Ingos work in progress at http://people.redhat.com/mingo/realtime-preempt/ that is becoming of less importance however. Mark
Vanilla Linux kernel never has deterministic behaviour, with RT patches we get a soft RT behaviour, but never hard RT. We haven't got deterministic behaviour because of ISRs preempt user land task always. As a matter of fact if we have got a only task in the system, when the system has heavy load in network nic (for instance) we will get no deterministic results. It's very important the difference betwen soft and hard real time.
