Agenda:Â
- 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)

Agenda:Â
- 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
- method 1: invite IVI, IC experts from other EG to join the 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)
- Option 1 (most strict): Only if the device has been upstreamed and official published in the OASIS specification
- How we can brainstorm what kind of virtio devices are necessary to AGL
- 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.Â

Agenda:Â
- Topic 1: Linaro Sharing for ALS PoCÂ 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:Â https://collaborate.linaro.org/pages/viewpage.action?pageId=147423498
