    Info

    Experience Level: Description Beginner: Task #1: webcam demo app - write an app exposing the v4l webcam feed your task will be to develop an QT/QML-based application to display the a webcam feed - talk to jsmoeller (at) linuxfoundation.org Intermediate: Task #2: demo app for the IIO service. Display sensor data from the iio-service on the display. Your task will be to develop an QT/QML-based application to show data from sensors - talk to jsmoeller (at) linuxfoundation.org Advanced: Task #3: Platform Development - create or enhance the container image Your task will be to either create or enhance a container-based setup using AGL - talk to jsmoeller (at) linuxfoundation.org Advanced++: Task #4 integration of ROS (Robot OS - meta-ros) - talk to jsmoeller (at) linuxfoundation.org Task #5 extend the jailhouse support

    
    

• VirtIO KK Release
  • VirtIO related documentation disappeared.
    https://docs.automotivelinux.org/en/master/
    • available on the git but not on the webpage (Jan-Simon Moelleris checking)
    • it seems to related to broswer cache and Jan to check further. But for virtio documentation it became alive again. https://docs.automotivelinux.org/en/master/#0_Getting_Started/2_Building_AGL_Image/5_4_Virtio/
• All Member Meeting (All Member Meeting (Mar 16~17)
  • https://events.linuxfoundation.org/agl-amm/program/schedule/
  • Introduction to Automotive Grade Linux - Walt Miner, The Linux Foundation
    • Mention Virt-EG work VirtIO? Any input/slide need from us?
    • Will introduce KK features
    • Jerry, Jiancong Zhaoto prepare a slide about Virt-EG work and send to Walt by 04 Mar 2021 
  • ((Virtualization Related) Obtaining VirtIO-enabled Virtualized AGL KK Reference Demo Distribution - Mikhail Golubev, OpenSynergy GmbH

• Follow-up of last workshop on VirtIO-gpu
  • Can VFIO on Intel be applicable to the zero-copy case?
    • Which address space are buffers in? Can we use IOMMU for that?
    • IOMMU is a must have to defeat against DMA attacks

    • Intel pioneered VFIO; Huawei did develop so called "warpdrive" technology → mainly for "server" hardware acceleration encryption & decryption (kind of passthrough but can be shared across different VMs)
      https://connect.linaro.org/resources/bkk19/bkk19-401/

    • Type 1 hypervisor can passtrhough device for guest VM easily. But driver need to be have in the front end guest. (will be dependent onto SoC platform)

    • 
      

      IOMMU should be able used but not used in the crosvm (instead, used host allocation). Coherent memory is needed.

    • Linaro Hiramatsu's comment: to share the memory between the guest, I think we need ivshmem like driver. (but that is not transparent)

      title Mail from Kenneth (Huawei)
      Hello, Jerry, Nice meeting you. We are happy to discuss UADK with colleagues of the same profession. We are just afraid that we cannot give what you need;).  Because it seems you are looking for VFIO rather than UADK. We tried to merge our requirement to VFIO initially. But we gave up after the first RFC. To us, the major down side of VFIO is that it is a practical device. But we don’t take it a device. We take it a heterogeneous CPU. In UADK, the process attach to the accelerator, the accelerator share whole or part of the address space of the process. So the process can deliver task to the accelerator without warrying how to copy data to the accelerator. So there is no independent device is created, no DNA operation is provided. It is just for sharing memory between CPU and the accelerator. Because of this, we solve different set of problem. E.g. we have to take care of process-cloning to duplicate/stop the interface to child process. But it seem you are looking for a solution to isolate some GPU resource for particular VM. This is exactly what VFIO trying to do. So now it is you who may want to tell me. Are you guys really want to know the detail of UADK? J Cheers
