Agenda: 

  • Topic 1: Yocto Architecture for VirtIO FEDD integration Mikhail Golubev
    • some SoC vendor's BSP kernel doesn't support Yocto Linux so that the virtio.scc may be not included.
    • it's better to maintain the front end driver or the kernel configuration in AGL.
    • Release candidate branch for AGL will be in January.
    • general idea is on master, but for recipe (patch and yocto layer only) → sandbox, source code → code repository
      Jerry, Zhao Jiancong need to check with Walt Miner on application of a new repository (JIRA ticket)

  • Marius Vlad - Collabora

Agenda: 

  • Topic 1: Future Plan of VirtIO Device in AGL
    • How we can brainstorm what kind of virtio devices are necessary to AGL
      • method 1: invite IVI, IC experts from other EG to join the discussion
        • Email in the mailing list is okay
        • Inter-EG activities are handled in the SAT
        • Announce & Invite in Dev Call is also possible (most people)
      • method 2: invite GENIVI AVPS member to share their progress on the automotive virtio discussion
    • What is our policy to decide which device should be integrated into AGL
      • Option 1 (most strict): Only if the device has been upstreamed and official published in the OASIS specification
        • Publish of OASIS specification will be the trigger for AGL virtio porting activities
      • Option 2 (moderate): If the device has been upstreamed and has a certain plan to be included in the OASIS specification in near future
      • Option 3 (most loose): Any devices that Virtualization EG members have consensus

        Discussion:
      • Upstreamed drivers are mandatory
      • Depending on AGL kernel version, some new devices may not be included. Backporting from the newer kernel is needed (in some circumstances, trouble may happen) → discuss whether it can be integrated in the form inside kernel trees or out of the kernel trees
      • New device drivers (not upstreamed) has the similar situation with the above

        Conclusion:
        Depending on the maturity of the virtio device drivers, we can put into different places → all virtio drivers can be integrated in this way
      • Recipe: Put the new drivers to the meta-agl-devel for developing and testing, integrate the stable drivers in the meta-agl.
      • Source Code: Staging (new drivers) & Src (stable drivers)
  • Topic 2: OpenSynergy Plans for ALS VirtIO PoC & AGL KK Contribution Mikhail Golubev
    OpenSynergy will distribute the PoC after KK contribution as a reference implementation of VirtIO. Jan Simon has suggested distributing methods such as "accepting terms" which already used by some AGL mebmer.

Agenda: 

  • Topic 1: Linaro Sharing for ALS PoC Victor Duan (Deactivated)
    • AGL is working as a guest (front end)
    • Hypervisor: KVM & Xen
    • Hardware: different ARM boards (Socionext Developer Box, Armas 8040 MacchiatoBin)
    • portability across different platform (independent from SoC & Hypervisor)
    • virtio devices: virtio-net, virtio-blk, virtio-gpu. future: virtio-video, virtio-rpmb and etc.
    • no special preference on whether virtio-pci or virtio-mmio
    • the memory access limit will be not in the scope of the demo
    • Xen hypervisor: similar approach to crosvm
    • Original Target: End of this month (but it is postponed)
    • for the ALS: blk, network and framebuffer (audio will be difficult for the current schedule)
    • Work will be open.
    • Progress can be traced in the following path: https://collaborate.linaro.org/pages/viewpage.action?pageId=147423498

  • Topic 2: ALS Presentation & AGL KK VirtIO Porting Progress Checking
    - Linaro: Jellyfish
     a) KVM works fine. → working fine on the real board
     b) Xen Dom0 works fine.  has some trouble with DomU (on QEMU is okay, but on hardware still some ongoing issues)?
       Xen virtio implementation → only supported virtio blk device

    - OpenSynergy:

    Mikhail Golubev  please upload the slides you presented here.
    on-schedule for the KK virtio porting



  • Suggestion: Upload the demo video of EG PoC after ALS demo onto the AGL official Youtube channel
    Pending Mikhail Golubev Victor Duan (Deactivated) to check internally if this is okay

Agenda: 

  • Topic 1: VirtIO KK Porting Progress Mikhail Golubev
    • AGL KK progress is fine.
    • only virtio-input multi-touch patch is still not available because not upstreamed in the Linux kernel main line (waiting for the LKML to accept)
    • Yocto machine: merged in the AGL and additionally 
    • Question: demo image (set-up)
      → hypervisor distribution: Mikhail Golubevcheck internally
      → QEMU can also be also considered.
      Victor Duan (Deactivated) tell us where we can find the implementation of Linaro's ALS QEMU demo  
    • Question: Passthrough for GPU-3d?
      • yes, for ALS
      • for KK porting and reference implementation. VirtIO-gpu3d will be used insead
