1. Why should we learn the kernel? Some people want to learn the kernel, while others do not. If you want to engage in system development or driver development in the future, you must learn the kernel. I just got started with the kernel and mainly learned kernel interface fu
Linux0.11 Kernel Analysis-kernel architecture and linux0.11 Architecture A complete and available operating system consists of four parts: hardware, operating system kernel, operating system services, and user applications, as shown in: User applications refer to the word processing programs, Internet browser programs, or various applications compiled by the user
1 kernel Object definition:1.1: Each Kernel object is just a block of memory allocated by the kernel and can only be accessed by that kernel.1.2: the memory block is a data structure whose members are responsible for maintaining various information about the object.Some data members (such as security descriptors, usage
I. Description of BOOTM BOOTM This command is used to start an operating system image. It obtains some information from the head of the image file, which includes the CPU architecture of the image file, its operating system type, the type of image, the compression method, the load address of the image file in memory, the entry address of the image file to run, the image filename, and so on.The BOOTM then loads the image to the specified address and, if necessary, extracts the image and passes t

Linux Kernel overview, Linux kernel Overview Linux Kernel learning notes. Unix Unix has a history of 40, but computer scientists still regard it as the largest and most outstanding System in the existing operating system. It has become a legend and remains well known after time. In 1973, after the Unix system was rewritten in C language, a large number of Unix-de

Article title: comparison between Linux kernel and traditional Unix kernel. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. All Unix kernels are of the same origin and provide the same API. modern Unix kernels have many design

The kernel is a very small part of the entire operating system. According to Google's R D strength, it is not that difficult to develop a kernel? Is it really difficult to develop the kernel, or is Google making Android use the Linux kernel based on some considerations? The kernel
On the Structure and generation process of kernel ----- (1), kernel ----- TodaySo many servers and workstations around us run linux, so many friends want to understand the core mechanism of linux. However, as the kernel is too large, some friends are discouraged. (I also had this experience when I was in my sophomore year. When I saw some people watching
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

In addition, server applications o
Recently, I have been studying the Linux kernel. The kernel upgrade process is a learning process before I can carefully study the significance of the kernel, first of all, I have successfully compiled and upgraded from kernel 2.6.31.2 to 2.6.35.7 on Ubuntu. However, during compilation and upgrade on fedora, errors occ
