 Agenda

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

 Discussion topics

• MH: We had a lot of grand plans which we didn’t get to but what was done was a success

• MH: We need to pick something that feeds into a wider Blueprint

  • MP: difficult to get engaged without an obvious finish line

  • MP: couldn’t do everything as we were short of resources

  • RL: I agree focus on tangible, focus on specifics

  • MH: ST have a proposal to connect remoteproc with VirtIO, ARM and EWOL VirtIO stuff

  • BM: lots of places where the tech can be extended, find an actual use-case. GPU would be a big effort if no one was going to use it

  • AO: meeting time may have been a factor, we should show leadership picking a particular use case

  • BM: hypervisor-less VirtIO is an ambiguous name (Different things to different people)

  • BM: Take GPIO/I2C or Block backends on an R5 for example

  • BM: is it virtualisation or VirtIO? Not so sure about the hypervisor independence

  • AO: portability is a goal but maybe only 20% is portable atm

  • LG: AGL want VirtIO for hypervisorless for emulation (cloud native vs deploy to HW)

  • BM: 80% portability is a worthwhile goal

  • AO: what does it actually take to enable

  • LG: AGL is far from its goal, not progressing fast enough - focus on more meaningful use cases

  • MP: we have lots of drivers in kernel, bus driven devices tend to be interoperable

  • MP: how do we pick the winners from the herd of problems and use cases

  • AO: I don’t think there are bigger fish solving these VirtIO problems

  • BM: Stratos was chasing the shiny problems but plenty of basic stuff to solve

  • BM: was hoping we would have a better use case definitions from Arm by now

  • RL: members looking for defined timelines for projects, pick and be definitive

  • MP: but the picking is the problem

  • MH: and a division between cloud native and HPP

  • AO: and the remaining foundational work blocking other stuff?

  • RL: can we show progress and attract members

  • MH: maybe we should spend a bit of time on Bills end

  • AG: Cloud Native not really happening

  • BM: look for a 2 person project rather than a 5 person one where we only work with member engineers

  • MH: should we push a fresh pitch

  • AO: agree - lets push on the BPs rather than under the umbrella of Stratos

  • MP: we can extend on the Stratos work even if we don’t work under that

• What next - discussion became Linaro only internal, and the results will be published when this bottoms out

• Broadly

  • Pivot Stratos towards possibly Arm-sponsored external contribution of virtio work to meta-eawol / TRS

  • Take LEDGE member lead BP from ST, attractive to Xilinx, Arm and NXP and look at HPP usecases
