Building a linux device driver

2. Building support for a media device — The Linux Kernel documentation. 2. Building support for a media device ¶. The first step is to download the Kernel’s source code, either via a distribution-specific source file or via the Kernel’s main git tree 1. Please notice, however, that, if: you’re a braveheart and want to experiment with. Building and Running Modules - Linux Device Drivers, 3rd Edition [Book] Chapter 2. Building and Running Modules. It’s almost time to begin programming. This chapter introduces all the essential concepts about modules and kernel programming.

Now issue the kernel module compilation by typing: ~/ldd3$ make -C ~/linux ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- M=`pwd` modules make: Entering directory `/home/tanzilli/linux' CC [M] /home/tanzilli/ldd3/hello.o Building modules, stage 2. There are two ways of programming a Linux device driver: Compile the driver along with the kernel, which is monolithic in Linux. Implement the driver as a kernel module, in which case you won’t need to recompile the kernel.

Fundamentals of Linux kernel module and writing syntax. Makefile and LKM build procedure. Character device driver implementation. Not necessary to compile the whole kernel to write a device driver in Linux. The modular based approach in Linux will help you compile the module.
