Introduction to Linux device driver development (based on the latest 4.0 kernel)

Linux never stops. Linus Torvalds, one of the greatest programmers in the world, founder of the Linux kernel, and Git creator, are still combining patches and upgrading the kernel day and night. As a technology, there has never been a shortcut, but it is a silly effort to sit on the bench.

This is an era in which even reading is fragmented. In this era, people tend to be radical and impetuous. Inner peace makes it very difficult for us to calm down and study what. I have met many Linux engineers whose resumes are "proficient" in the Linux kernel and have many years of working experience. However, their "proficient" only changes a register from 0 to 1, from 1 to 0, I have seen many Linux engineers working hard all day, hitting their own machines and circuit boards, but they have never calmed down and thought, and constantly reconstruct and sublimate your knowledge system.

This is a programmer who wants to stick to the ground. So busy programmers are never good programmers.

The best quality of a good programmer is to be able to learn and think about problems with peace of mind, and to analyze the architecture, principles, and design ideas behind the code. Code without thinking is spam code. Programmers without thinking are just physical workers who have finished repetitive construction at a low level. Many programmers never even ask how to run their own code on the machine. Many things happen inexplicably, and many bugs disappear inexplicably ...... It will always be the same.

As a result, the first starting point of the new version of "Linux device driver development details" is introduced to readers.
