Topics & Notes:

Check past action items

• Previous meeting notes: https://github.com/elisa-tech/wg-systems/wiki/Feb-24,-2025-%E2%80%90-16:00-UTC
• AI-Sebastian: Involvement of DIN can also be interesting. Sebastian will take a first contact.
  • Communication started. Another meeting scheduled in Feb.
• AI-Philipp: Add architecture picture to Systems-WG repo for better clarity.

Standards Atlas

• 2nd deep dive performed. Interest in the topic overall, but not to have immediate action.
• Next sync in fall 2025 to see where the automated train project proceeded with it.
• In case of sufficient interest and driving it (e.g. with BASIL) than picking up earlier is always possible.

Railway WG formation

• Working group proposal: https://docs.google.com/document/d/12YAObVbfqeNXOSREpNmHvZDqUiqXBypAgnMP3j37VVE
• Good progress in preparation of proposal.
• Pending MGMT approval from potential participants.
• Next meeting proposal: Tuesday 2:00 PM on May 6th is seen as best date to meet again.
• AI-Philipp: Create invitation for the next Railways WG meeting May 6th 2:00 PM CEST
• What drives the working group topics?
  • Overall strategy from the governing board
  • Major topics for cross collaboration (and reporting of topics) in TSC
  • Workshops create many topics.
  • Working groups come up with topics of interest and members of group define what they work on.
  • Blog https://elisa.tech/blog/2025/03/05/elisa-project-achievements-updates/ shows 2025 goal

Example system composition

• During Embedded World AGL presented a SDV architectural proposal utilizing AGL IC + IVI with Xen and Zephyr
• Idea from AGL might be to bring this on top of Renesas hardware and ARM Graviton image (AGL is not 100% set there)
• Idea for ELISA Systems WG: take yocto full image to create a (qemu) image with meta-zepyhr and meta-virtualization.
• Could be based on AGL or a plain yocto. Both worth to try.
• Xen-Troops worked out of the box with recent release for S4. It is based on current LTS version. No graphics.
  • Moulin is build tooling for it (maintained by epam)
  • Default config is Dom0 and DomD. DomU is optional.
• autoSD or CentOS can also be options.
  • first have an autoSD running.
  • see if e.g. S-Core can be applied on top of the example system (discussion happened today in S-Core working group).
  • -> Good topic for the ELISA workshop in May
• approach potential automotive partner and hardware vendor with a working system
• Xen to build Dom0 and spawn other DomUs e.g. based on CentOS with podman inside.
• x86 architecture may be a point as well as they bring the confidential computing hardware blocks and it can be checked how they can be used for safety.
  • This would imply KVM most likely or maybe kata container.
  • x86 is a major topic in railway industry and also for robotics/industrial applications.

Good Quality Practices in Open Source [cont.]

• Worked on gdoc draft to work for the LFE requests: https://docs.google.com/document/d/1Uzp4-mAAOd9uMhyKx5Vaa0C8Mq5w1IxhHFAgyE0I9p0
• Survey: https://docs.google.com/forms/d/1qSJ_tixVK2ZkwyTNBK-Hk4trOZwitca-v3xPwFaQepA
• Press release: https://docs.google.com/document/d/15VeKQQgjV-tfR8c4b3tnZgfaIEx27gI0XFxZ-5UicRc
• Next:
  • Bring the draft towards LF Europe end of the week. --> Mae wants to reach out to LF Europe
  • Have it published in LF Europe and ELISA newsletter e/o March.
  • Collect feedback in April
  • Use it for OSS NA in June.
• Make sure that Kate speaks to Gabriele Columbro during LF member summit

AoB

• Re-Scheduling WG meeting (topic for next meeting)
