The application I used is a small controller for robot developped by people in the lab. Before it used to be in RTAI. But now they are trying to use Xenomai. The application is splitted in two parts: the user side which saves data, manages interfaces and the kernel module which realise all the real time tisk (sampling, writing to electronic card, controler). The communications between the two is made by 5 pipes (command, parameters, acknowledgment, save, status).
This is why i need to make my sqrt() function (of double variables) into my kernel modul part.

I am a beginner with > Xenomai. Is there any math_module which already exists ? Counter question: Why do you need to use math in kernel code? It is generally a sign something is not well split-up between kernel-based driver code and user-space RT applications. To answer your question: No, Xenomai does not come with a kernel math lib because there is not much use for it - generally. Porting the app to user-space is recommended.
