Safety-Critical Software Summit

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, Philipp Ahmann, Technical Business Development Manager at Robert Bosch GmbH and Chair of the ELISA Project TSC, presented a session titled, “ELISA Status and Outlook: Advancing Open Source Safety-Critical Systems.”

These days, open source software can be found in almost every reasonably complex product running software. It runs in medical devices, robots, vehicles, and even outer space. In the underlying industry sectors, certification and safety integrity standards play an important role which at first glance seem at odds with the use of pre-existing open source software, not developed strictly in accordance with industry standards.

In this video, recent ELISA project deliverables in the field of elements, processes, and tools are highlighted. These include system theoretic process analysis, workload tracing, call-tree visualization on kernel level, and reproducible example use-cases from the field of medical devices and automotive. Their role in reducing the burden for companies to build and certify open source based safety-critical applications is shown. Additionally, an overview of upcoming ELISA activities in 2023 is provide and how cross project collaboration is established, as the ELISA work streams include interaction with e.g. the Zephyr, Xen, AGL, yocto, and SPDX community. A few statements on the overall challenges of safety-critical use cases using free open-source software will help to pick up those audience which is new to safety-critical or open source development.

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, Nicole Pappler, CTO and Founder of AlektoMetis, and Philipp Ahmann, Technical Business Development Manager at Robert Bosch GmbH and Chair of the ELISA Project TSC, presented a session titled, “Coding Guidelines – to Comply or Not Comply – Some Myth Busting.”

While adhering to certain coding styles is a good practice in software projects, adhering to coding guidelines for safety critical applications is still something rather exotic in open source projects. As open source projects now more and more start to address the needs of functional safety applications, considering coding guidelines preferred by existing functional safety projects seems to become necessary. The most used rules for coding guidelines in the safety critical context are MISRA rules. While applying these can be quite beneficial for most applications, there is a significant number of exceptions where blindly following these rules causes more problems than it solves.

In this video, Nicole and Philipp discuss the most common coding guidelines, best practices and arguments when following the MISRA rules conflicts with the expectations of the project. Acceptance criteria for non-compliance cases along with examples of acceptable deviations will be presented. This is not contra coding guidelines, but illustrates how coding guidelines are beneficial for a project, what to consider when designing a project’s coding guidelines and how the lessons learned by the application of MISRA rule sets can be applied to languages that are not (yet?) covered by widely accepted rule sets.

Shuah Khan

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.

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, Stefano Stabellini, Fellow at AMD, and Bertrand Marquis, Principal Software Engineer at ARM, gave a presentation titled, “Safety Certifying an Open Source Project: The Example of Xen.“

Safety is important to software everywhere human lives are at risk. In these environments, safety standards must be followed to minimize the risk to humans and to follow regulations. Safety standards such as ISO 26262 come with a series of requirements and processes that sometimes clash with well-established Open Source software development practices. How do we reconcile safety certifications and Open Source?

This presentation will provide some insights to answer that question, using the Xen hypervisor as an example. Xen has a micro-kernel design and provides a virtualization solution for embedded and automotive while having a code base small enough to make certifications possible. This presentation will go through the changes to upstream processes that the Xen community adopted during the last 12 months to align community activities with safety-certification requirements. It will discuss any additional changes planned for the near future. The talk will also cover the latest updates from the Xen FuSa working group on MISRA C, traceability, testing, etc. Watch the video below:
