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

The process of understanding process scheduling and process switching during the time-tracking analysis processGrasping Writer: Li Pengju No.: 20132201(* Original works reproduced please specify the source *)(Study course: "Linux kernel Analysis" MOOC course http://mooc.study.163.com/course/USTC-1000029000)First, the experimental requirements: To understand the timing of process scheduling in Linux

Simple Method for tracking multiple time zones in Ubuntu Whether I want to wake up with a tweet about Australia's chrome book sales sold out, or remember to make a Skype call with half of Ohso's developer Sam Chan, my brain needs to work in multiple time zones at the same time. There is a problem there. If you know me

process has set the TLF_NEED_RESCHED flag for the current process, and if so, the entire schedule () function restarts, otherwise the function ends. The core function of the Linux dispatch encapsulates the framework of the kernel scheduler for the Schedule,schedule function. The detail implementation invokes the function implementation in the specific scheduling class. When the switching process has been selected, the processing of the user's virtual space begins, and then the process switches

Local variables are indexed by%EBP registers, that is, by N (%EBP), n is the compile-time decision, and N is the same local variable in the same piece of code in different processes. In Switch_to, a stack switchover occurred, that is, EBP changed, so pay extra attention to which process the local variable belongs to at any one time. The call to the __switc

%EBP registers, that is, by N (%EBP), n is the compile-time decision, and N is the same local variable in the same piece of code in different processes. In Switch_to, a stack switchover occurred, that is, EBP changed, so pay extra attention to which process the local variable belongs to at any one time. The call to the __switch_to () function is not implemented by ordinary calls, but by direct jmp, where th

switch_to does a critical process context switch5, after the label 1 starts to run the user state process Y (here Y has been switched out through the above steps so you can continue from the label 1)6, Restore_all//recovery site7.

Iret-pop Cs:eip/ss:esp/eflags from kernel stack8, continue to run the user-state process ySeveral special cases:1, through the interrupt processing process scheduling time, the user state process and the kernel thread switch between each other and the kernel thread switch to each other, and the most common situation is very similar, but the kernel thread runs in the process of interruption without proc

actively calls schedule (), only the process context of the switch, there is no interrupt context switch, and the most general situation is slightly abbreviated; The system call that creates the child process starts in the subprocess and returns the user state, such as fork; A situation in which a new executable program is loaded and returned to the user state, such as EXECVE; Li JosenOriginal works reproduced please indicate the source"Linux kernel Analysis" MOOC course http://moo

Summary of the experimentThrough the study of this course, I have a certain understanding of the process scheduling timing and process scheduling and process switc
