We introduce GPU sharing between virtual machines on an embedded hypervisor. To achieve GPU virtualization, we apply an API remoting method which requires low overhead to OpenGL ES. For multimedia application, we target in-vehicle infotainment system and configure two guest virtual machines. The digital cluster is implemented on a bare-metal virtual machine. Furthermore, for multimedia application, we implement a linux-compatible 3D navigation. The framework can display both guest virtual machines on a single display panel so that output could be allocated separately on the panel. With this work, we explored how to virtualize GPU on a hypervisor for automotive systems.
