ELISA Ambassador: Philipp Ahmann

By Ambassador Spotlight, Blog

ELISA Ambassadors are technical leaders who are passionate about the mission of the ELISA Project, recognized for their expertise in functional safety and linux kernel development, and willing to help others to learn about the community and how to contribute. 

Each month, we’ll put a spotlight on an ELISA Ambassador. Today, we’re excited to highlight Philipp Ahmann, ambassador and TSC member within the ELISA project as well as software manager at ADIT (a joint venture of Robert Bosch GmbH and DENSO Corporation).

Background Details:

Philipp Ahmann is manager at ADIT (a joint venture of Robert Bosch GmbH and DENSO Corporation) and has been participating in the ELISA project since the start.

He has more than ten years of experience in automotive infotainment base platforms, utilizing complex multi-core system-on-chips (SoCs). Also, he is leading a group of engineers who are responsible for software integration (CI/CD), testing, development infrastructure and tooling within ADIT.

His automotive expertise started with integration of components in SoC hardware and printed circuit board (PCB) design for the same. From there, Philipp moved over to the field of software development with initial responsibility for bootloader and Linux software board bringup.

After working within the Linaro community and several years as lead of the test development within ADIT, he became software project leader. The projects mainly target OSS based in-vehicle-infotainment base platforms on various hardware variants. Nowadays also build infrastructure as well as software base platforms for autonomous driving products are in his responsibility.

Q&A

How long have you been active in open source?

My first open source work was done as a user. While I was studying in Sweden in 2006, a friend and I collected old university PCs from the electronic scrap and installed Ubuntu 6.10 on them. Afterwards we maintained and distributed them to exchange students who couldn’t afford an own laptop or PC.

Really active in open source, I became a member of the Freescale landing team within Linaro in 2011 to drive ARM Kernel and BSP development for i.mx6 SoC forward.

Tell us about your favorite open source project and what problems did it aim to solve?

It is really hard to define my favorite open source project as they are everywhere in my life. My private NextCloudPi gives me full control over my data. Home Assistant integrated perfectly with ESPHome and is helping me to automate tasks in my flat and surrounding for higher convenience and energy savings. LineageOS, CarbonROM, /e/ brought back new life to old smartphones serving as daily drivers for my kids and parents making technology more sustainable. 

Thanks to projects likes Linux Mint, which shows decent performance even on old devices, old PCs and laptops get a second life. On devices tools like LibreOffice, Red Notebook, Freeplane, Arduino IDE, VS Code and others, help me to structure my day and increase productivity. For fun and entertainment there are projects such as Kodi and RetroPie.

Overall, I am pretty sure everyone touches open source at one time or another, since open source software rules the world. It is there, where people need it. From the people for the people. A big thanks and kudos to all of you who participate in open source projects. 

What roles and/or working groups do you have or participate in?

I am acting as an ELISA ambassador and was recently elected as a technical steering committee member. 

I host meetings, act as moderator, write minutes and jump in where I can help to drive topics forward and where my support is needed or wished.  For technical content, I mainly contribute within the Automotive Working Group, where I benefit from my many years background in Linux for Automotive.

Where do you see the ELISA Project in three years?

Since I am primarily active in the Automotive WG, I would like to try to make a forecast for this group. In 3 years, we will have completed and showcased our first use case, which is a telltale application.The created work products will act as a blueprint to get the first fully Linux-based instrument cluster on the market. 

What is the biggest strength of the ELISA community?

The biggest strength of the ELISA community is the diversity, which we achieve with experts from many different working fields, domains, industries and interests from all across the globe. The diversity of perspectives, coupled with the transparency and communication, is crucial to the success of safety relevant projects. By sharing our concepts, we get a lot of feedback from e.g. the Linux and the safety community. Of course there are passionate in-depth difficult discussions, but these are open and not driven by commercial interests. Risks, potential gaps or also any other concern is addressed from the beginning. 

If we continue on this path, the results from the ELISA community can act as state-of-art technology and as a benchmark for many safety critical systems in the future. We contribute to a safer world.

3 Fun Facts:  

  • I once repaired an entertainment system of a plane during the flight and asked the pilot if he could use the internet connection in the cockpit to search for a Windows NT dll file for me. If you are curious about the root cause, get in touch with me.
  • Already twice I have been on an overseas business trip and my luggage was delayed for so long that it got delivered only the day before departing again. Luckily, I bought at least a T-Shirt in Paris before going to NYC.
  • I built an Arudino based music player with RFID and arcade button control. It took me a year from the first PoC to be robust enough for my kids. At the time I was done, my daughter learnt how to use an Android phone and preferred a touch display and cover flow. So I put a custom rom on a phone, flashed it, and removed any unintended services to make it a kids-ready data-privacy device. This took me only a week in the end.

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).

ELISA Project Mentorships – Apply Today!

By Blog

The ELISA Project is sponsoring two part-time summer mentorships, which runs from June 1- November. ELISA Project Ambassador Lukas Bulwahn will be mentoring both projects.

Linux Kernel: Checkpatch Documentation

Previous mentees have been evaluating, re-visiting and improving the checkpatch script and its various rules. Towards the end of the mentorship, they have also started to document the rules and their rationales (with references to previous discussions and documentation), but not all rules are fully documented yet. The task in this mentorship is to continue evaluating the rules, identifying the known typical false positive cases, writing the documentation of the rules and explaining the rules’ rationales and known false positives. Apply here: https://mentorship.lfx.linuxfoundation.org/project/a6565ff5-b07c-4c04-98db-3a470917d497

Linux Kernel: Mining for Maintainers

Jonathan Corbet identified in his article MAINTAINERS truth and fiction [https://lwn.net/Articles/842415/] that about 2,800 files in the kernel repository have no dedicated maintainer in the MAINTAINERS file (see https://lwn.net/Articles/842606/ for the full list of files). Jonathan Corbet sets out the call for action: “the vast majority are header files under include/, most of which probably do have maintainers and should be added to the appropriate entries.” The task in this mentorship is to follow this call for action and add the header files under include/ to the appropriate entries. Apply here: https://mentorship.lfx.linuxfoundation.org/project/8f69e012-08d0-4e2b-baa7-9143b5f98823

ELISA Project Welcomes Codethink, Horizon Robotics, Huawei Technologies, NVIDIA and Red Hat to its Global Ecosystem

By Announcement

SAN FRANCISCO – April 19, 2020 –  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 Codethink, Horizon Robotics, Huawei Technologies, NVIDIA and Red Hat has joined its global ecosystem.

Linux is used in safety-critical applications with 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 which decreases the issues that could result in loss of human life, significant property damage, or environmental damage. Launched in February 2019 by the Linux Foundation, ELISA will work with certification authorities and standardization bodies across industries to document how Linux can be used in safety-critical systems.

“Open source software has become a significant part of the technology strategy to accelerate innovation for companies worldwide,” said Kate Stewart, Vice President of Dependable Embedded Systems at The Linux Foundation. “We want to reduce the barriers to be able to use Linux in safety-critical applications and welcome the collaboration of new members to help build specific use cases for automotive, medical and industrial sectors.”

Milestones

After a little more than two years, ELISA has continued to see momentum in project and technical milestones. Examples include:

  • Successful Workshops: In February, ELISA hosted its 6th workshop with more than 120 registered participants. During the workshop, members and external speakers discussed cybersecurity expectations in the automotive world, code coverage of glibc and Intel’s Linux test robot. Learn more in this blog. The next workshop is scheduled for May 18-20 and is free to attend. Register here.
  • New Ambassador Program: In October 2020, ELISA launched a program with thought leaders with expertise in functional safety and Linux kernel development. These ambassadors are willing to speak at events, write articles and work directly with the community on mentorships or onboarding new contributors. Meet the ambassadors here
  • Mentorship Opportunities: The Linux Foundation offers a Mentorship Program with projects that are designed to help developers with the necessary skills to contribute effectively to open source communities. A recent program, ELISA participated in the Fall 2020 session with Code coverage metrics for GLibC and a Linux Kernel mentorship focused on CodeChecker. This project supports ELISA’s goals to gain experience in using various status analysis methods and tools available in the Linux kernel. Learn more here.
  • Working Groups: Since launch, the project has created several working groups that collaborate and work towards providing resources for System integrators to apply and use to analyze qualitatively and quantitatively on their systems. Current groups include an Automotive Working Group, Medical Devices Working Group, Safety Architecture Working Group,  Kernel Development Process Working Group and Tool Investigation and Code Improvement Sub-Working Group to focus on specific activities and goals.

Growing Ecosystem

After a little more than two years, the ELISA Project has grown by 300%. With new members Codethink, Horizon Robotics, Huawei Technologies, NVIDIA and Red Hat, the project currently has 20 members that collaborate to define and maintain a standardized set of processes and tools that can be integrated into Linux-based, safety-critical systems seeking safety certification. These new members join BMW Car IT GmbH, Intel, Toyota, ADIT, AISIN AW CO., arm, Elektrobit, Kuka, Linuxtronix. Mentor, Suzuki, Wind River, Automotive Grade Linux and OTH Regensburg.

“Codethink has been working with ELISA for a few years and we are excited to continue our engagement as a member,” said Shaun Mooney, Division Manager at Codethink. “Open Source Software, particularly Linux, is being used more and more in safety applications and Codethink has been looking at how we can make software trustable for a long time. We’ve been working to understand how we can use complex software and guarantee it will function as we want it to. This problem needs to be tackled collectively and ELISA is a great place to collaborate with experts in both safety and software. We’ve been working with most of the working groups since the start of ELISA and will continue to be active participants, using our expert knowledge of Linux and Open Source to help advance the state of the art for safety.”

“Safety is the most important feature of a self-driving car,” said Huang Chang, co-founder and CTO of Horizon Robotics. “Horizon’s investment into functional safety is one of the most important ones we’ve ever made, and it provides a critical ingredient for automakers to bring self-driving cars to market. The creative safety construction the ELISA project is undertaking complements Horizon’s functional safety endeavor and continued commitment to certifying Linux-based safety-critical systems.”

“Huawei is one of the most important Linux kernel contributors and recently joined the automotive industry as strategic partner in Asia and Europe,” said Alessandro Biasci, Technical Expert at Huawei.“ We are pleased to further advance our mission and participate in ELISA, which will allow us to combine our experience in the Linux kernel development and knowledge in safety and security to bring Linux to safety-critical applications.”

“Edge computing extends enterprise software from the datacenter and cloud to a myriad of operational and embedded technology footprints that interact with the physical world, such as connected vehicles and manufacturing equipment,” said Chris Wright, Chief Technical Officer at Red Hat. “A common open source software platform across these locations simplifies and accelerates solution development, while supporting functional safety’s end goal of reducing the risk of physical injury. Red Hat recognizes the importance of establishing functional safety evidence and certifications for Linux, backed by a rich platform and vibrant ecosystem for safety-related applications. We are excited to bring our twenty-seven years of Linux expertise to the ELISA community’s work.”
