RTAI vs. voluntary kernel preemption?

[M. Koehrer]

Hi everybody,

in the latest kernel 2.6.13, the voluntary kernel preemption patch is integrated.
What's the benefit of RTAI against this preemption patch?
I want to run a task periodically (let's say every 400 microseconds) and I want to communicate via UDP (Ethernet) within this task, is this possible using the voluntary kernel preemption patch?

I know it works using RTAI and rtNet, however as rtnet supports only very few network adapters I am looking for a way to do this using a "standard" linux with the standard network drivers.

Any comments on that are highly welcome!

Thanks

Regards

Mathias
