Hello Wolfgang,

Actually I didnot ask the question clearly, sorry for that. I want RTnet in
RT-Preempt kernel. Very happy to know that you are working on it. May I know
when it will be available?
I am a starter in Linux so I want to know & explore more on RTDM. Suppose if
you assign me the same task of porting RTDM over linux kernel services with
rt-preempt patch, How I have to proceed? Any tutorial or manual can you
please suggest me.

Sorry for the stupid question.

Thanks and regards
Saiful
