Linux Features WG evolution

  • Alessandro will take over along with Vikas as co-chair
  • Focus on Linux Kernel (in past also topics around in user space)
  • Priorities and roadmap described in slides by Alessandro.
  • Start with Boot and continue with Scheduler
    • Boot was not really touched in the past, but often requested to be touched by ELISA.
    • do not go too deep into the bootloader before the kernel.
    • concentrate on kernel boot from where the point the kernel gets executed.
      • work on the commonalities and maybe look at specifics like architecture later.
    • concerns on what firmware does under the hood.
      • x86, dts/dtb, system-ready and other firmware may have impact on boot and are highly system dependent.
  • PREEMPT_RT to be continued as part of scheduler.
    • Current draft work on PREEMPT_RT can be found here
    • For further realtime considerations also need to reach out to Shuah and Rob
  • TSC agrees with the proposed strategy
  • Can start with the formalities
    • Current description of WG can be modified, if needed: https://lists.elisa.tech/g/linux-features
    • Alessandro will review to check if changes are needed.
    • Alessandro will be named as chair and Vikas as co-chair.
    • New meeting time to be informed by Alessandro to Min. May have it 1h earlier than before.

    • Consider a blog post and inform about the roadmap and the way to get involved.
