Agenda

• New topics
  • Review update to dentOS issue tracker with feature request issues
  • "ONLP rewrite to use kernel subsystems"
    • is this the best path to invest in?
    • Setup follow-up meeting to discuss userspace platform management tools (IE: what ONLP does now)
    • Take a high level look at what makes sense across wired switches, wireless APs, and any other device types the DENT project may want to support
    • Steve Noble thinks ONLP shim is possible and best option at least in short term
    • Sartura doesn't like obtrusiveness and complexity of ONLP and suggests examination of what is minimally required to expose enough functionality for end users to develop exactly what they need
    • Mellanox does not use ONLP on Spectrum platforms
    • Participants: nvidia, Sartura, amazon, ...?
  • Upstream focus as feature
    • kernel upstream board support packages from ODMs instead of ONLP
    • need to determine viability and how DENT project could/should support ODMs in achieving this
    • possibly double edged sword?
    • how to handle non-public platforms
      • custom developed platforms
      • proprietary to ODM
      • etc

Actions

• Delta to provide PoE controller software specification
• Amazon to supply PoE daemon requirements
• Need to develop specification for 802.1x driver portion
• Create issue with build system evaluation criteria
• Develop vendor agnostic driver feature requirements list
• Marvell will update Prestera Switchdev wiki with current features (Moti)
• Create github issue in dentOS repo for support model discussion
• Setup follow-on platform configuration and support meeting
