These projects focus on the and Kernel Mode Setting (KMS) , which are the modern standards for managing display hardware.

Move into the graphics stack by creating or porting a driver for simple hardware, such as an SPI-connected OLED or e-ink display. Port an existing driver to the modern subsystem. Key Concept: Implement the mode-setting pipeline, including the Framebuffer (Display Controller). Resources: Reference out-of-tree repositories like
