Introduction to the Linux kernel module the overall structure of the Linux kernel is already very large, and it contains many components. How can we include all the required parts in the kernel?One way is to compile all required functions into the

One: The origins of LinuxLinux is an open-source computer operating system kernel. It is a Unix-like operating system written in C and POSIX compliant, and Linux was originally developed by Finnish hacker Linus Torvalds to try to provide free and free Unix-like operating systems on the Intel x86 architecture. The program began in 1991 with the help of some minix hackers in the early stages of the program, a

After running make menuconfig, the system's configuration tool first analyzes the/arch/arch/kconfig corresponding to the architectureThe file (the Arch argument that appears here is at the end of this article). It actually refers to the second, another important role------introduction of Kbuild Makefile The Kconfig file helps the user complete the confi

first, the kernel timer 1. Basic ConceptsIn some scenarios, we need to do some action after a certain time, but do not want to wait and waste the CPU, this time the timer is a very appropriate mechanism. The timer is used to perform a function at a future point in time to accomplish a specific task. The kernel timer tells the kernel to use specific parameters to
