The Real-Time Driver Model (RTDM) is an approach to unify the interfaces for developing device drivers and associated applications under real-time Linux. The device models supported by RTDM will be introduced in this paper. An overview of the low and high level APIs will be given and the concept of device profiles for defining generic device interfaces will be presented. Moreover, the integration of RTDM in Xenomai will be explained and a survey of already available applications of this concept will be provided.
