find contain a lot of code related to specific machines. What we are more concerned with is the main mechanism of code to be analyzed, instead of machine-related special code (this helps us better understand the nature of the kernel ). Therefore, we need to carefully select the materials that involve code files. Of course, this step is unlikely to be completed at one time, and no one can guarantee that all source code files to be analyzed can be sele

Processes are one of the core concepts of modern operating systems and are used to allocate the use of systems (CPU, memory) resources. Understanding the Linux process and process switching knowledge, first to understand the difference between the process and the program, the process is the execution flow, is a dynamic concept, the program is a collection of data and instruction sequence, is a static concept. It is important to understand that the pro

In the previous article, a process was introduced, and the process of stack changes when calling subroutines was analyzed. This article describes the process of multi-process execution, when a process needs to stop to wait for a certain condition or the CPU to allocate the time slice run out need to switch to another process, when the switch first generates an interrupt, then the CPU will perform the corresponding interrupt processing operation, An important operation, for example, is to protect
