The implementation is similar to the GPU-based Gralloc module.
Since graphics systems are so complex, we will continue exploring this topic a little more when looking at VirtualBox-specific implementation in the next chapter. We will explain the loading process of Gralloc HAL and OpenGL ES libraries. We will build a VirtualBox extension pack for Android so that we can utilize the capability provided by VirtualBox. ...
