Although the latency properties of the Linux kernel have improved substantially in the past years, it is not yet a "realtime" operating system out of the box. Today there are two approaches available to improve on this. The RT Preempt patch set contains kernel wide changes improving the whole system, while a dual-kernel approach introduces a small separate scheduler below the linux kernel.

This presentation gives an introduction to both scenarios and the resulting requirements for developers using them will be explored. The Xenomai dual-kernel approach will be described in more detail together with its broader aim of providing a roadmap to existing realtime systems using proprietary systems like vxWorks, pSOS and others.

Latest developments like SMP support on Cortex A9 ARM systems will be presented and an outlook to the upcoming Xenomai 3 release will be given.
