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, Jiancong Zhao need to check with Walt Miner on application of a new repository (JIRA ticket)
Topic 2: VirtIO Backend Related Sharing Laurent Cremmer

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
- 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 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 tell us where we can find the implementation of Linaro's ALS QEMU demo
  - ALS image is the qemuarm64 JJ image from the website
  - QEMU is lightly patched: https://patchew.org/QEMU/20201105175153.30489-1-alex.bennee@linaro.org/
- Question: Passthrough for GPU-3d?
  - yes, for ALS
  - for KK porting and reference implementation. VirtIO-gpu3d will be used insead
Topic 2: ALS Presentation from Demo Jerry, Jiancong Zhao
- General arrangement for ALS Jerry, Jiancong Zhao
  - Jerry, Jiancong Zhao will ask for the registration code for
- ALS Demo sharing with Q&A - Linaro VICTOR DUAN Alex
  - backend for real hardware: put it into the Dom0
  - Dom0 can be directly
- ALS Demo sharing with Q&A - OpenSynergy Mikhail Golubev
