Heterogeneous VirtIO for Automotive Computing
Project Purpose
The Heterogeneous Virtio for Automotive Computing (HVAC) project works to deliver the flexibility, power, and standardization of Virtio to platforms with Linux and RTOS running on various CPU cores types and topographies. HVAC will demonstrate these capabilities in a realistic manner for Automotive use. It is expected that the technology itself will be applicable to other markets as well.
In addition the HVAC project will serve as a community focus point to drive the virtio-msg technology which will form the basis of most of the HVAC work.

Overview
The HVAC project will deliver the following:
Virtio between two OS’es that do not share a hypervisor
Virtio device and driver on Zephyr while maintaining real-time performance and functional safety
QEMU as a Linux user-space device model provider for these systems
Linux kernel as a virtio driver side (device consumer)
Xen as a hypervisor for Linux and RTOS
QEMU as a development and demonstration platform for these systems
A demonstration on real hardware aimed at the automotive market
The Technologies above should provide value in lots of use cases including:
Linux + RTOS (or no OS)
RTOS + RTOS
Linux + Linux
Inside a container or as a hypervisor guest
In co-operation with secure world components as needed
Heterogeneous cores on one SOC
Heterogeneous systems constructed via PCIe interconnect

Roadmap
The project is marching toward a demo in the first weeks of January 2025 using AMD hardware that is an X86 host and an onboard ARM SOC (w/FPGA) that is connected via PCIe.
