Not too long ago even in the Open Source community there was a debate going on whether a general purpose kernel such as Linux could be converted into a real-time kernel or not. Meanwhile it has become clear and is generally accepted, that this is, in fact, possible and that such an adapted Linux kernel is suitable in a wide variety of industrial real-time applications. To convert the Linux kernel into a real-time kernel was, among others, an important rationale when founding OSADL. Since January 2016, the Linux Foundation has been taking care of coordinating the real-time development and raising funds for it (Linux Foundation RTL Project). OSADL is contributing to this project as a Member and, as such, representing the automation industry in the consortium.
The Linux kernel developers have a strong need for feedback of users of the respective industrial sectors, in order to not only guarantee the high quality of the Linux kernel in general, but also with regard to the sector-specific requirements. As far as the automation industry, mechanical engineering and embedded systems are concerned, OSADL has taken over this task and is running a corresponding test center - the so-called "OSADL QA Farm". In order to achieve the widest possible range of realistic scenarios, OSADL carries out various continuous 24/7 measurements on more than 130 different types of embedded systems in the QA Farm. An important part of these measurements is the determination of the real-time capability of the systems and their runtime stability.
