Before contributing to the kernel, you must master the Linux kernel coding style. This is a short but strict document describing the preferred style for kernel code. The style is opinionated—indentation must be 8 characters, using hard tabs, not spaces. The rationale is that deep indentations warn you when you are nesting functions too deeply, encouraging you to refactor your logic. The line length limit is generally 120 columns, and you are expected to burn copies of the GNU coding standards as a symbolic gesture (the kernel developers have a famously irreverent sense of humor).
obj-m += hello.o all: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules clean: make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean Use code with caution. Step 4: Compile and Test
Kernel space operates with direct mapping but relies heavily on virtual memory. You will learn the difference between kmalloc() (physically contiguous memory, ideal for DMA) and vmalloc() (virtually contiguous memory, used for large buffers), alongside mastering the slab allocator to prevent memory leaks.
