Jan, Please understand that I will not merge any ha^w"extensions" on top of > an RT Linux variant, neither RTAI nor any other approach.

This are basic threading primitives and they *should* be provided by drvlib.c I will convert the driver to use rtdm_task_init_cpuid & al but I would welcome some sample code. What is cpuid? Would 0xFF do? Regards, Vlad
