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 |
