The ELISA Project Continues to Grow its Global Ecosystem by Welcoming Red Hat as a Premier Member and Banma, Lotus Cars and SUSE

By Announcement, News, Working Group, Workshop

Schedule for the ELISA Fall Workshop on November 8-10 is now live

SAN FRANCISCO – October 20, 2021 – Today, the ELISA (Enabling Linux in Safety Applications) Project, an open source initiative that aims to create a shared set of tools and processes to help companies build and certify Linux-based safety-critical applications and systems, announced that Red Hat has upgraded its membership to premier member and welcomes Banma, Lotus Cars and SUSE as the newest members.

Linux is used in all major industries because it can enable faster time to market for new features and take advantage of the quality of the code development processes.  Launched in February 2019 by the Linux Foundation, ELISA works with Linux kernel and safety communities to agree on what should be considered when Linux is to  be used in safety-critical systems.

“Linux underpins many applications today that have safety-critical and cybersecurity implications,” said Kate Stewart, Vice President of Dependable Embedded Systems at The Linux Foundation. “By collaborating together, the ELISA members are defining the best practices for use of Linux in these systems. We look forward to continuing to build consensus and welcoming expertise and collaboration from these new members.”

Attend the Fall Workshop

Since its inception, ELISA has hosted quarterly workshops that bring together project members and community contributors to discuss working group updates, trends in functional safety, use cases and more. The next workshop will be held virtually on November 8-10 and is free to attend. Speakers include thought leaders from Arm, Codethink, Elektrobit Automotive GmbH, Evidence Srl, Google, Intel, Mobileye, The Linux Foundation, Red Hat and UL LLC. Register and check out the schedule: https://events.linuxfoundation.org/elisa-workshop/. 

Join the New Working Groups

Since launch, the project has worked to establish a governance model that creates processes and guidance to the focused working groups that aim to provide resources for System integrators to apply and use to analyze qualitatively and quantitatively on their systems. Today, ELISA announces two new working groups:

  • Open Source Engineering Process Working Group: This working group aims to examine safety-related claims that we might like to make about Linux as part of a system, and to explore how we can gather and present evidence to support such claims.
  • Linux Features for Safety-Critical Systems Working Group: This working group will work to bring together kernel developers and producers of safety critical systems to demonstrate use of such features in real systems, and to learn from these experiences together as a community. Learn more about this new working group in this November Workshop session. 

Learn more about the Global Ecosystem

Red Hat, which is known for its leadership in linux and open source, joined ELISA earlier this year and has been very active in the technical community. With their upgraded membership to Premier, Red Hat welcomes Gabriele Paoloni, Open Source Community Technical Leader at Red Hat, as the ELISA Project Governing Board Chair.

“Red Hat announced our intent to expand our expertise in Linux to safety-critical automotive use cases earlier this year as we work to develop a Linux in-vehicle operating system,” said Francis Chow, vice president, In-Vehicle Operating System, Red Hat. “As such, we’re pleased to extend our participation in ELISA as a Premier member and collaborate with other industry leaders in building up open source software for applications that require extremely high levels of trust and functional safety.

A Guided Tour Through the PREEMPT RT castle

By Blog, Workshop

In May, the ELISA Project hosted its 7th Workshop with 239 participants from 37 different countries. For a complete recap of the workshop, click here. Today, we’ll take a look at one of the sessions titled “A Guided Tour Through the PREEMPT RT castle” presented by Thomas Gleixner, CTO at Linutronix GmbH.

The tour through the inner workings of PREEMPT_RT will start at the observation deck to give an conceptual overview. From there it will take the participants through the various chambers which contain a broad range of historic and contemporary operating system technologies. The tour will not only take the hallways it is also going to explore some of the secret passages and the brave-hearted can take a glimpse at the horror cabinets.

General knowledge about operating system concepts is recommended for taking the tour, but of course it’s open for everyone and all chambers have exit doors if it gets too spooky.

Linux in Basic Safety Applications

By Blog, Workshop

In May, the ELISA Project hosted its 7th Workshop with 239 participants from 37 different countries. For a complete recap of the workshop, click here. Today, we’ll take a look at one of the sessions led by Jason Smith, Principal Engineer at UL LLC, about the “Linux in Basic Safety Applications.”

Linux is more often being used in applications with safety relevance:

  • Complex safety-related functions necessitating the advantages of an OS, or
  • Complex end application necessitating the advantages of an OS, now being asked to perform one or more basic safety-related functions (for example: voltage, current, temperature monitoring)

In both cases, software used to implement the safety-related functions may be required to conform/comply with applicable functional safety standards.

In this presentation, Jason will discuss linux in basic safety applications, the goals and progress of the white paper the ELISA Project is working on and details about how to get involved.

Usability of ISO 26262 2nd Edition for an Open Source Design

By Blog, Workshop

In May, the ELISA Project hosted its 7th Workshop with 239 participants from 37 different countries. For a complete recap of the workshop, click here. Today, we’ll take a look at one of the sessions led by Roberto Paccapeli, Functional Safety Manager at Intel and Vito Magnanimo, Functional Safety Architect at BMW Group, about the “Usability of ISO 26262 2nd Edition for an Open Source Design.”

In the automotive domain, the reference standard for Functional Safety is ISO 26262. The normative does not currently provide a clear distinction between new Software design and pre-existing ones. This limitation directly impacts on open source designs, developed in accordance with non-standardized development process (e.g. Linux operations system). This video presents some of the gaps observed in the standard and introduces hints that can be jointly addressed with ELISA members without losing the cornerstone of the ISO (or in contrast with its clauses).
