 Agenda

List goals for this meeting (e.g., Set design priorities for FY19)

 Discussion topics

• VirtIO devices

  • AB: the wifi simulation was originally targeting UML

  • AJB: is it still a thing?

    • AB: yes, although not used in production anymore

  • AJB: exploring the use case for wifi

  • AJB: can netlink be plumbed into normal ethernet devices

    • AB: already is

    • AJB: so could we just add additional features to virtio-net

    • AB: I don’t see why not

    • AJB: who to talk to?

    • AB: maybe Lee Jones? probably bug fixes

  • AJB: any thoughts on on virtio-gpu

    • AB: fundamentally it’s HW specific

    • AJB: doesn’t OpenCL abstract things?

    • AB: lots of layers with trade offs

    • AB: virtio-gpu should work for a lot of the NPU abstractions

    • AB: although there are some simplere ones just matrix multipliers

  • AB: GVE

    • looks like a SR-IOV type device (much like AWS approach)

    • LG: could be SmartNIC with virtual devices

• Action items

  • VG: still to chase up SCMI bindings

 Action items
