Linux

Since I have recently studied the application and development of QT, the first step is to build a development environment. However, it is found that the hard disk space allocated to the virtual machine is obviously insufficient, resulting in the

This article summarizes how Windows XP and Windows 7 access the shared files in the linxu virtual machine. The system installed on the host is Windows 7, and the Linux version installed on the virtual machine is fedora (32-bit ). Run the following

Anyone who has learned C language knows that the memory of a process in UNIX is divided into three parts:CodeSegment, stack segment, and data segment. Code segments are used to storeProgramThe Running code, the stack segment is used to store the

  Most Linux systems run on PC platforms, but Linux is also very stable as an embedded system. This article depicts an overview of an embedded system and shows how embedded system products use Linux. The story of an embedded system older than

Reprinted from http://www.ibm.com/developerworks/cn/linux/l-ipc/part5/index2.html The system calls MMAP () to map a common file to implement shared memory. System V maps files in the SHM of a special file system to implement shared memory

PCI is a widely used bus standard. It provides many new features that are better than other bus standards (such as EISA) and has become the most widely used computer system, and the most common bus standard. Linux's inner nuclear energy well

First, make sure that the file type is executable. There are two ways to set the file as an executable file. 1) directly select "executable" in the file property tag, -- if B uses a graphical interface, this method is the simplest and most direct.

A frequently asked question in the Linux Kernel mailing list is how to patch the Linux kernel or, more specifically,There are so many trunk/branches that a patch must be installed on the basic kernel. I hope this document will help you understand

FTP servers are more common on the Internet. Linux FTP commands use commands to control file transfer between local and remote hosts, here we will introduce some frequently used Linux FTP commands in detail. I believe it will be very easy to master

I. kernel space The kernel space is mapped by the kernel. It does not change with the process and is fixed. Ii. High-end memory: The physical memory address exceeds MB, which we call high-end memory. 3. kernel space distribution chart (1) The

Experience summary: 1. Do not use an independent video card because the driver does not support the pv_ops kernel architecture. 2. Do not use a 64-bit release (except for Ubuntu) Steps: 1. Install 32bit opensuse 12.1 Install Linux kernel development

Note: The following content is installed in centos. Depending on the actual environment, there will be a lack of dependencies. I encountered a lack of xmlo during the installation process. If there is a problem, Google it, install the dependency and

2. Linux driver2.1 framebufferLinux is working in protection mode, so user-mode processes cannot use the interrupt call provided in the graphics card BIOS as DOS to implement Direct Screen Writing and Lin imitation graphics card functions, the

GTK is generally used to represent software packages and shared libraries, and GTK + is used to represent the graphic component set of GTK. In the process of developing gnome with GTK +, some new components were developed based on the above

Each process has a task_struct struct in the Linux kernel to maintain process-related information, known as process descriptor. In operating system theory, it is called a process control block (PCB, process control block ). Task_struct has a pointer

When writing a socket program in Linux, if you try to send it to a disconnected socket, the underlying layer will throw a sigpipe signal. After the client sends a message to the server through pipe, it closes the client. At this time, the server

Containers can provide lightweight virtualization to isolate processes and resources, without the need to provide command interpretation mechanisms and other complexities of full virtualization. This document describes the container tool Linux
