Automotive systems are evolving towards virtualization of a large and powerful SoC to control independent systems in the car. There is thus a growing need to virtualize display in an efficient and secure manner. This presentation will explain different ways to achieve display virtualization. We will cover both pass-through and para-virtualization and go through the pros and cons of each option. How display controller hardware design can help or hinder display virtualization will also be analyzed. While the principles will be generic, the examples will focus on automotive systems, and will be based on KVM and QEMU using a latest generation automotive hardware platform. As a last step we will go through issues specific to QEMU and KVM in an automotive environment, and see how improvements can be implemented.
