This page will be updated during the month and is not final until after the 1st week of March.

Summary of Month

Plans

  • Finish the 2nd draft virtio spec w/ virtio-msg in our fork and publish it as RFC.

  • Move x86 + Arm demo to a new board to show at Embedded World in March

  • Several items to make the emulated demo easier for people to run

  • Stretch: Rebase the Dual QEMU demo to the latest baseline and contain the shared memory usage to only the single IVISHMEM card

  • Stretch: Integrate the ST A7 Linux + M4 Zephyr virtio-i2c demo

Highlights

  • First RFC of spec went out on Feb 25

  • The demos (hvac-demo) now work on arm64 hosts

  • Demo container images are published at docker.io/wmills/hvac-demo (for now)

  • Multiple people have tested the demos and all issues have been addressed

Meeting Notes Feb 13

  • Only topic of the meeting was spec readiness for the 1st RFC targeted to next week

  • Bertrand’s PR #5 was well reviewed by Arnaud, Bertrand incorporated the input and Alex merged during the meeting.

  • Bill created some issues before and during the meeting, these were discussed during the meeting and Bertrand took the action to address them as he sees fit

  • We discussed RFC format and cover letter

    • RFC from: bill.mills@linaro.org

    • Signed-off-by: Bill @ Linaro, Bertrand @ Arm, Edgar @ AMD, Arnaud @ ST, Someone @ Google ??

    • Cover letter should point to:

      • HVAC intro slides

      • HVAC demo repo or container

      • Viresh’s kernel tree

      • Edgar’s QEMU tree

      • Arnaud’s OpenAMP library code

      • (Point out that the demos and code bases each use different state of the spec and are not aligned to spec RFC)

  • AI: Bertrand update for the issues list

  • AI: Bill to ask for Signed-off-by from: Edgar @ AMD, Armelle if someone from Google can signoff or at least make a statement of interest/commitment to use

  • AI: Arnaud & Dan to try hvac-demos

  • AI: Bill to make running a container easier and to publish a container image
