770 771 772 Chapter 17: Don't re-invent the kernel macros 773 774 The header file include/linux/kernel.h contains a number of macros that 775 you should use, rather than explicitly coding some variant of them yourself. 776 For example, if you need to calculate the length of an array,...
Linux Kernel >= 2.6.0 Linux模块简介 首先这个module不同于microkernel的module,microkernel的module是一个个的daemon进程,工作于用户空间,Linux的module只是一个内核的目标代码,内核通过执行运行时的连接,来把它整合到kernel中去,所以说Linux的module机制并没有改变Linux内核为monolithic OS本质,其module也是工作于内核模...
It presents kernel functions and data structures, steps the reader through them, but does not, for example, emphasize the rules for using them. UTLK is a study guide, not a programming manual.本书描述了内核函数和数据结构,引导读者穿行于其间,但是,并没有着重强调使用它们的法则。UTLK是一本学习...
-- Now updated throughout to cover Linux 2.4. -- Explains how the Linux operating system actually works and shows how to program the Linux kernel. -- Introduces the kernel sources and describes basic algorithms and data structures, such as scheduling and task structure. Linux Kernel Internals,...
Kernel modules offers an easy way to extend the functionality of the base kernel without having to rebuild or recompile the kernel again. Most of the drivers are implemented as a Linux kernel modules. When those drivers are not needed, we can unload only that specific driver, which will redu...

This book covers the vast field that is Linux Kernel Programming with sufficient amount of detail needed for module/driver development. The book is a hands-on guide as each chapter features example code, designed to illustrate the presented topics, which you can try out for yourself. Along with...
The 2nd Edition of Linux Kernel Programming is an updated, comprehensive guide for new programmers to the Linux kernel. This book uses the recent 6.1 Long-Term Support (LTS) Linux kernel series, which will be maintained until Dec 2026, and also delves into its many new features. Further, th...
If there are any compile errors then you might have a more recent kernel version or need to install the corresponding kernel header files. 4 Hello World 4.1 The Simplest Module Most people learning programming start out with some sort of hello world example. I don’t know what happens to ...
In our example, this is automatically assigned by the kernel. However, you’ll need this value to create the device. Take the value you obtain from “make test” and use it to create a device file so that we can communicate with our kernel module from user space. $ sudo mknod /dev/...
