Meeting Notes Jan 30

• Spec Review:

  • All issues and PRs due by: Wednesday Feb 12, (sooner is better)

  • Discussion at next meeting: Thursday Feb 13

  • [Editors work to incorporate all PRs and Address Issues deemed needed for RFC]

  • RFC target: Friday Feb 21

• Sprint:

  • We are looking to do another sprint right before Linaro Connect 2025

  • This would be Tuesday May 14 in Lisbon

  • Doing this is dependent on getting 2 or 3 participating / interested members: Arm, Google, AMD, Qualcomm

  • Others may join as well: ST, Wind River etc

Updates:

• Edgar and Bill

  • Edgar has publish information on how he is doing the X86 + Arm PCIe demo

  • AMD has loaned Bill the two boards needs and he has replicated the demo

  • A new wiki page has been crated to describe and track this demo: AMD x86 + ARM PCIe based AMP Demo

  • Next steps are to port this demo to the smaller single board solution. Critical path of this is new board bring-up → FPGA design port → new BOOT.bin

• Google/Arm/Linaro

  • FFA work

  • Linux / Trusty is getting closer

  • Linux FFA for VM to VM is going upstream and making good progress

• Edgar:

  • Can we build virtio-msg as a module so we could add to existing distro (DKMS etc)

  • Viresh thinks it can be and is already done that way in Android.

Spec Review of PR #5:

• Bertrand reviewed his version asking specific opinions and made specific notes

• Bertrand will publish a new version next week
