Purpose and Rationale

The Hypervisor Project follows after two successful workshops at the last is producing a common open licensed Automotive Standard Virtual Platform specification based on VIRTIO, and other standards.

On the more general scope, the project two GENIVI All-Member-Meetings and investigates the wide scope of open- source and commercial hypervisor technologies, and addresses challenges in their use.

   Through collaboration between all vendors, experts and adopters of virtualization technology we can lower the barriers to successful product development.

  The project primarily drives requirements, standardization for Hypervisor APIs, and other types of investigations to facilitate ECU consolidation, price reduction, and management of mixed-criticality in systems for improved security and functional safety.

You can look below for detailed backlog and topics, but to summarize there are two There are three primary work streams currently in development:

1. Virtual Device API standardization, leading to the definition of the Automotive standard Virtual Platform
   (this builds on existing standards like VIRTIO naturallycollecting and driving requirements for a standard platform based on VIRTIO, SCMI, and other existing standards.
   

2. Multi-OS system design on Multi-Core SoCs (with/without virtualisation)
3. Investigate and recommend electrical/software architecture for automotive use-cases, when deployed using virtual-machine technologies.

Every Monday, 10:00 AM CET

Agenda:

• Technical Summit sessions (Bangalore, 10-11 October)
• Progress on actions: API standardization / virtual platform definition
• Discuss reference received from Bernhard (email)
• Discussing the format of the Automotive Virtual Platform specification (GA)
• possibly some other things

• Planning deep-dive topic meetings to take a break from pure AVPS writing.

General backlog

• AVPS v2 completed --> AVPS JIRA tickets for tracking 
• Whitepaper planning (dormant at the moment)
• Deep-dive Memory Buffer sharing (GPU) - suggested by Eugen Friedrich
• Update Milestones, deliverables, and workplan.
• Use-cases, architectures and requirements workstream (dormant)
• Re-review scope of workand synergy opportunities,  AGL virtualization EG.  Links to previous papers below.
• Establish scope of work and synergy opportunities for virtualization in AUTOSAR
• Android and Trout, evaluation and establish relationship to AVPS.

summary

Topic Introduction:
Virtual Device standardization, a.k.a. Automotive Virtual Platform definition

Common Define common I/O devices for hypervisor guests with standardized features and interface, such that device drivers (and thereby systems) are as a consequences systems, virtual-machines) become more portable.

Advantages:

• Device drivers (for paravirtualization) for the (Linux*) kernel don't need to be maintained uniquely for different hypervisors
• Ability to move hypervisor guests between different hypervisor environments
• Definite potential for shared experience and getting the right functionality into the APIs.  
  • Heterogeneous cross-system testing will strengthen specs and implementation.
• Some potential Some potential for shared device driver driver implementation across hypervisors across hypervisors (dependent on licenses - open-source, closed-source)

*virtio also supported by BSD, Windows, Fuchsia, and others
