printk(KERN_INFO "Simple graphics driver exited\n"); Hands On Projects For The Linux Graphics Subsystem
In this project, we will build a simple graphics driver that can render a graphics primitive, such as a triangle, on a Linux system. We will use the kernel-mode graphics driver framework, which provides a set of APIs for interacting with the graphics hardware. Finally, we will use DRM to render graphics on our device
