Using libdrm (a thin wrapper over the kernel's DRM ioctls), write a C program that: // Animation loop (15 seconds) for (int frame=0;

Process A (the producer) allocates a buffer and exports it as a file descriptor. On Linux, the "real" backend is VK_KHR_display and

Vulkan's WSI is a pluggable interface. On Linux, the "real" backend is VK_KHR_display and VK_EXT_direct_display . Most apps don't use it because it requires master DRM.

Write a simple X11 application using the Xlib library to create a window, draw shapes, and handle events. This project helps you understand the basics of X11 and its programming model.
