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

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
