Real Time Linux in Safety-Critical Systems: The Potential and the Challenges

The Linux Foundation hosted the Embedded Open Source Summit (EOSS), a new umbrella event for open source embedded projects and developer communities to come together under one roof for important collaboration and education, in Prague, Czech Republic, on June 27-30. More than 1,300 people registered for the conference – representing 375 organizations across 56 countries around the globe.

EOSS hosted the Safety-Critical Software Summit, which was sponsored by the ELISA Project, that gathered safety experts and open source developers to enable and advance the use of open source in safety-critical applications. As part of the Summit, Elana Copperman, ELISA Ambassador, Linux Features for Safety-Critical Systems WG Chair and Systems Safety Architect at Mobileye, and Shuah Khan, ELISA Ambassador, member of the ELISA TSC and Linux Fellow at The Linux Foundation, gave a presentation titled, “RTL in Safety-Critical Systems: The Potential and the Challenges.

The Real Time Linux (RTL) collaborative project was established to help coordinate the efforts around mainlining Preempt RT and ensuring that the maintainers have the ability to continue development work, long-term support and future research of RT. The RTL project has been active in adding Preempt RT features in to the mainline kernel. It is time for a closer look on how these features can be used in Safety-Critical Systems.

In this video, we provide a brief overview of Real Time Linux and potential usage in Safety-Critical systems. In addition, we discuss how these features may be relevant to support system safety. We go over the following areas that are most relevant:

1. Tools for analysis of system workload resource usage and performance impact.

2. Kernel configs, guidelines on usage.

3. Relevant system parameters, generic and architecture specific.

4. Test frameworks and how they may be used to investigate and demonstrate safety features.
