Minutes

• Data Center Group updates
  • Confidential Computing
    • The activities of this project are spread amongst multiple teams inside Linaro. We are creating a new project to coalesce all these activities.
    • Ongoing investigation about the current state of the Confidential Computing on Arm platforms. Details in next meeting topic.
  • System Ready Compliant Platform Collaboration (SRCPC)
    • Focusing on the next set of features in the roadmap.
    • Qualcomm was working on a new feature to add versioning to the SBSA references in QEMU, but they are not working on that anymore. Linaro pick up this work.
    • SMMU stage 2 functionality has been upstreamed, but we are still trying to make some changes to satisfy the ACS tests.
    • Working on few bugs related to PCIe root.
  •  Etcd
    • CI is running. There is a pending issue that was not reproduced. In theory, we are ready to become Tier 1 supported.
    • The remaining issue is who in the Arm community is willing to become the maintainer of this project. The community wants that a maintainer of the etcd community becomes the Arm maintainer. That will demand that anyone looking to get this position will need to first become very involved with the etcd community. This is out of the scope of what Linaro can do here at this moment, unless we change the Data Center Group priorities.
  • Tensorflow
    • 2.13-rc0 is out. Things are looking good at this point, so not sure if an rc1 will be needed.
  • Storage
    • Lustre
      • Lustre on OpenEuler has been accepted and will be in the next OpenEuler release.
      • 4k page CI still not running. We do have a 64k CI running, but community doesn't have lots of interest on hat.
  • Big Data and Data Science
    • BigTop now supports OpenEuler.
    • Version 3.3 work has been started.
• Confidential Computing on Arm investigations
  • ICYMI, Arm provided lots of good information on their efforts during Linaro Connect and in presentation to the Confidential Computing Consortium. Pointers below.
    • LHR23-304 - Runtime Security Subsystem [Arm CCA HES] - An overview
    • LHR23-311 - Arm Confidential Compute Architecture open-source enablement
    • LHR23-315 - Confidential Containers (Coco) on Arm CCA
    • LHR23-319 - Arm CCA Linux Support
    • Arm CCA open-source enablement (presented to the Confidential Computing Consortium, with information from LHR23-311 and LHR23-315)

      • Google drive docs
