Minutes

  • Project updates

    • Deploy CCA on Arm Platforms (DCAP)

      • Port of the CCA support to QEMU's SBSA reference machine is completed. We can now boot an emulated Arm environment with RME support and launch a QEMU/KVM Realm from within it. Patches are still being worked.

      • Updated the Build and run CoCo/Kata Container with RME Support documentation with end-to-end instructions on how to deploy containers and run the Trustee verification service.

      • Extended the iatverifier tooling in tf-m-tools and the Veraison's CCA packages and crates to support the updated CCA realm token encoding defined in IETF draft-ffm-rats-cca-token-oo. The CCA realm token will encode RAK as a CBOR-serialised COSE_Key rather than a raw public key.

      • Keybroker service presented by Paul Howard, from Arm, in the last meeting, had progress on the development of an MVP: https://github.com/veraison/keybroker-demo.

      • Fujitsu started working on libvirt support for Realms.

      • Our test verification service running Veraison has been offline for the past days due to a network outage in our lab. We are investigating the issue.

    • System Ready Compliant Platform Collaboration (SRCPC)

      • Switched from OpenBSD to FreeBSD in QEMU CI checks as current OpenBSD does not boot on Neoverse V1 and Neoverse N2. The latest is the default processor used in QEMU SBSA machine type now.

      • Have SMMU with stage1 and stage2 support at the same time.

      • Pass SBSA level 3 checklist. Marcin Juszkiewicz updated the BSA / SBSA check list table he maintains: https://marcin.juszkiewicz.com.pl/download/tables/bsa-sbsa.html

    • Performance Optimization (PO)

      • Jira project created: https://linaro.atlassian.net/jira/software/c/projects/PO/boards/312.

      • As usual with Data Center Group projects in Linaro's Jira, this is a public project. Anyone should be able to view its issues. If you want to actively contribute, please let me know and I can request a user for you.

      • We will transfer the backlog in the next section to the project Jira in the next few weeks.

    • Big Data and Data Science (BDDS)

      • ZhiGuo Wu has been hired for the project. His start date is 8 October.

      • @Kevin Zhao will help with ZhiGuo onboarding and will work with him and Huawei on a revised roadmap for the project.

    • Enhanced Software-Designed-Storage on Arm Servers (STOR)

      • Completed Ceph SPDK NVMe-oF Gateway evaluation on Arm64. Working on performance optimization of some components now.

      • @Kevin Zhao presented a good overview of the project, its accomplishments and its future roadmap in the Linaro TSC call yesterday.

  • Performance optimization status and back log

    • BoostKit: Huawei

    • Numpy

      • Community recently added a new feature called Universal SIMD Intrinsics, currently only supported on x86. Linaro will work to add proper support for Arm.

  • Preparation for the next Data Center Group steering committee meeting and the Linaro Partners Meeting.

    • As we did in the past two years, I would like us to do a review of our current strategy and direction in the October Data Center Group steering committee meeting.

      • What are the main goals for your company in the next year within the Data Center Group? What is your biggest interoperability issue today? What is your number one priority that you would want help from this group to solve?

    • This will also serve as a preparation for the Linaro Partner Meeting (LPM), where members usually present their priorities and what projects they think should continue or stop inside Linaro.

    • In the Data Center Group steering committee meeting just after LPM, on Tuesday, 5 November, at 3 PM Ireland time, I will try to bring project leaders to talk about the accomplishments in each project for the past year.

  • Events

    • Open Source Summit China (OSS-China) and KubeCon China: 21-23 August, 2024, Hong Kong, China

      • @Kevin Zhao attended.

        • AI/LLM was a big topic, as usual these days.

        • Usage of Kubernetes on edge deployments by Kubeedge was a hot topic. This is already used by some automotive companies, but no one is applying confidential computing to this use case yet.

        • Ant Group announced the creation of an affiliate called Ant Group Secret Computing Technology which will provide privacy computing solutions based on confidential computing support.

      • https://www.lfasiallc.com/kubecon-cloudnativecon-open-source-summit-china/

    • Open Source Summit Europe (OSS EU): 16-18 September, 2024, Vienna, Austria

    • Linux Plumber's Conference: 18-20 September, 2024, Vienna, Austria (co-located with OSS EU).

      • @Mathieu Poirier attended the Confidential Computing Microconference.

        • The segregation of a TEE's memory to run services, such as vTPM, is getting traction. Planes is the solution for Arm Realms. For AMD's SEV-SNP, SUSE and others are already working on coconut-svsm to support the same concept.

        • There was a presentation around Trustee.

        • Verification is getting more and more attention. The talk from Usama on Attested TLS generated a lot of heat.

        • Device assignment work has started. Device assignment and TDISP will go hand-in-hand.

      • https://lpc.events/

    • Confidential Computing Mini Summit: 19 September, 2024, Vienna, Austria (co-located with OSS EU).

      • @Thomas Fossati attended. I wasn't able to talk to him yet and get his feedback.

      • Registration is done together with the OSS EU registrations (there is an option to register to the co-located conferences).

    • Linaro Partners Meeting (LPM): 4-5 November, 2024, Dublin, Ireland

      • We will have a Data Center Group face-to-face steering committee meeting happening just after LPM, on Tuesday, 5 November, at 3 PM Ireland time.

    • KubeCon North America: 12-15 November, 2024, Salt Lake City, UT, USA

    • Open Source Summit Japan (OSS-Japan): 5-6 December, 2024, Tokyo, Japan

    • UXL will be hosting oneAPI dev summits in Asia and Europe/USA in the future. These are being organized.

    • Any other events where we could collaborate or where you think Linaro should do a demo or present.
