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
