The process of understanding process scheduling and process switching during the time-tracking analysis process

1. Understand the timing of process scheduling in Linux systems, you can search the kernel code for the schedule () function, see where the schedule () is called, to determine whether the summary of our course content is accurate;

2. use GDB Trace to analyze a schedule () function to verify your understanding of Linux system process scheduling and process switching process, and recommend to complete the experiment in the lab building Linux virtual Machine environment.

3. pay special attention to and carefully analyze the assembly code in Switch_to, understand the switching mechanism of the process context, and the relationship with the interrupt context switch;
