Agenda

• New topics
  • scrub B-release feature issue list for future releases
    • Reviewed driver supported features for B-release milestone items
    • Closed, moved or updated items for B-release
    • Need to discuss telemetry at next TSC call
  • scrub C-release feature issue list
  • project goals discussion
    • what is main objective of DENT project?
    • how best can we enable the user to accomplish their goals/desires with "products" of the DENT project/community?
  • what should be in the dentOS released images?
    • min set of packages
  • identify features that need a decision point
    • wireguard (strong interest/use potential in this)
    • telemetry
  • "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, ODMs [Delta, Accton, WNC]

Actions

• Delta to provide PoE controller software specification
• Amazon to supply PoE daemon specifications for external contributors (Carl Roth)
• Need to develop specification for 802.1x driver portion
• Develop vendor agnostic driver feature requirements list
• Marvell will update Prestera Switchdev wiki with current features (in process)
• Create github issue in dentOS repo for platform support model discussion
• Setup follow-on platform configuration and support meeting (duplicate)
• Setup Marvell driver development process discussion with Kishore and Moti (occurred)
