Role of AGL in Virtualization Standardization

OASIS: general standard on virtio specification
GENIVI - AVPS: automotive-centered specification
AGL: coding & implementation for real automotive use (more close to real product)

Virtualization EG Roadmap in 2020

Support VirtIO in AGL
- Multi-VM VirtIO PoC
- VirtIO White Paper
- Coding to Support Virtio in AGL

Purpose: To show the features and evaluate performance for VirtIO automotive use
Define common specification, architecture and evaluation items for the EG PoC
- Discussion on VirtIO Devices to be used in different automotive use cases (IVI, IC, Telematics)
  - what virtual devices should be used
  - how the virtual devices should be used (pass-through/front-end/back-end)
Implementation
- HW:
  - Emulators (QEMU)
  - SoC: TBD
    - Options:
      - Renesas M3/H3 (H3 is hard to get)
      - Qualcomm Board
      - QEMU x86
      - other companies' SoC
  - HW: TBD
    - Options:
      - Renesas Reference Board
      - LEGO
      - ...
- SW:
  - Hypervisor: Any OSS/commercial hypervisor that supports VirtIO
  - Front-end Device Driver: Open Source
  - Back-end Device Driver: Proprietary for most of the case (QEMU has open source backend)
- How:
  - idea: break down to several PoCs with incremental features
    - step 1: common/basic feature only
    - step 2: more advanced feature
- Who to implement:
  - option 1: voluntary implementation from members (PoC in the name of the company/community)
  - option 2: get funding support from Linux Foundation (PoC in the name of AGL community)
- Potential Target Event:
  - 2020.9 AGL ALS
  - 2021.1 CES2021
  - 2021.3 AGL AMM

Purpose:
- A summary of virtio discussion in AGL Virtualization EG
- To include topics such as standardization in automotive virtualization (virtio) in the whitepaper
Previous AGL Virtualization White Paper: https://www.automotivelinux.org/blog/2018/06/20/agl-publishes-virtualization-white-paper/
Possible Topics:
- Role of AGL in virtualization standardization (compared with other OSS promoting community such as OASIS and GENIVI)
- VirtIO Related
  - What is VirtIO and why it is important
  - How VirtIO can be used in automotive (uses cases in IC, IVI, Telematics)
  - Sample VirtIO-based architecture
  - Performance Indicator/Criteria for different virtual devices. Possible open source tools for the evaluation.
- Future of Standardization in Virtualization of Automotive (such as virtio-backend standardization)

Yocto layer to enable user to choose whether to use VirtIO or not.
