Enable Direct Rendering Manager (DRM) kernel debug logging: set drm.debug=0x1f boot parameter, inspect dmesg, and debug display stack output.

While out-of-tree loadable kernel modules ( .ko ) are useful for out-of-band development, integrating a driver into the Linux kernel source tree allows it to be configured via make menuconfig and compiled statically ( vmlinux ) or as a modular driver target. Step 1: Create driver directory and C s
