To build and debug Linux kernel modules for embedded targets, you need to set up Kbuild for out-of-tree or cross-compiled builds, apply module_init and module_exit conventions, and use insmod, rmmod, and modprobe workflows for runtime validation.

Linux loadable kernel modules fail to load or cause taint warnings when missing kernel-specific rules like MODULE_LICENSE declarations or proper symbol exporting, which this Skill helps identify and correct during module authoring.

Setting up cross-compilation for out-of-tree kernel modules on automotive IVI systems requires configuring Kbuild build environments and applying vendor-specific embedded Linux kernel headers to ensure proper module compilation and deployment.

Yes, this approach supports both out-of-tree and in-tree module development for automotive HUD and RSE Linux systems, handling metadata, printk logging, and module parameter declarations effectively.

The best way to diagnose Linux kernel module load issues is to inspect kernel logs using printk logging, manage symbol exports, and utilize modinfo to verify module parameter metadata and licensing compliance.
