Purpose and Rationale

The Hypervisor Project is producing a common open licensed Automotive Standard Virtual Platform specification based on VIRTIO, and other standards.

On the more general scope, the project 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.

There are three primary work streams currently in development:

  1. Virtual Device API standardization, leading to the definition of the Automotive standard Virtual Platform
    collecting 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.

Project Pages summary


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

Define common I/O devices for hypervisor guests with standardized features and interface, such that device drivers (and 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 for shared device driver implementation across hypervisors (dependent on licenses - open-source, closed-source)

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

Extending this: Standardizing a contract/standard between guest and hypervisor.  Compare the OCI initiatives for containers.  Container runtimes → can we have standardized "hypervisor runtime environment" that allows a standards compliant virtual (guest) machine to run.

  • Hypervisors can fulfil the specification (with local optimizations / advantages)
  • Similarly, this specification is what guests can be engineered to.

Compare: Linux Device Tree – ability to discover and configure devices.
