1. Configure the Environment Operating system: CentOS 5.2 Download linux-2.6.18 version of kernel, URL: http://www.kernel.org Description: The compiled document is suitable for 2.6. More than 18 of the Linux kernel version, only the compiled Linux kernel version can not be lower than the Linux operating system itself

When CentOS updates the kernel, many startup items will be added during startup. we can delete the old kernel and keep the latest kernel so that some disk space (/boot) can be released ). (1) view the installed kernel command: rpm-qkernel display result: kernel-2.6.32-279.14

Article Title: Use kgdb to debug Linux kernel and kernel modules. 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. 　　1.

Introduction to Linux Kernel Now let's look at the architecture of the Gnu/linux operating system from a relatively high altitude. You can consider the operating system from two levels, as shown in Figure 2. Figure 2. Basic architecture of Gnu/linux operating system The top is the user (or application) space. This is where the user application executes. Under User space is the kernel space, where the L

Because I do not have a real machine environment, so I need to simulate in the simulator, so I want to download the source code version of the support simulator, and the goldfish version is specifically provided for the simulator environment. The Goldfish project contains the kernel sources for the emulated platforms. One, first, to git clone https://android.googlesource.com/kernel/goldfish.git downloads

Article Title: How is the Linux kernel module transferred to the 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. Lsmod reads the/proc/modules file to check which kernel m

Read the platinum file written by the sibling in the 2.4 kernel. IptablesAdd a module and try it in the 2.6 kernel. After one and a half days of hard work, refer to the platinum article, Finally succeeded, write it down and share it with the Cu guys, my system is fedora2 + linux-2.6.5-1.358 1. Install the kernel source code.[Root @ jiecho] # Yum install

Kernel synchronizationSynchronous introductionThe concept of synchronizationCritical section: Also known as the critical segment, is the code snippet that visits and operates shared data.Competition conditions: 2 or more than 2 threads are running at the same time in a critical section, which constitutes a competitive condition.So-called synchronization. In fact, to prevent the formation of competitive conditions in the critical area.Assuming that the

First, How does the Linux kernel organize the files in each directory tree and compile them? and build a kernel with specific features as needed? in theLinuxin the kernel, there are two types of files:Makefile,Kconfig. The two files are distributed in the various levels of the kernel directory (each level corresp

CentOS deletes the old (kernel) kernelWhen CentOS updates the kernel, many startup items will be added during startup. we can delete the old kernel and keep the latest kernel so that some disk space (/boot) can be released ).(1) view installed kernelsCommand: rpm-q kernelShow results:

Differences between Linux 0.12 kernel and modern kernel in memory management Linux 0.12 kernel memory management is relatively simple and crude. The kernel only uses one page Directory and can only map 4 GB linear space. Therefore, the virtual space (Logical space) of each process can only be 64 MB, A maximum of 64 pro

Linux network subsystem Kernel Analysis, linux subsystem Kernel Select route To send data packets to PC2, the linux system queries the route table to see that the 168.1.1.10 (Destination Address) gateway address is 192.168.1.1. In this case, the linux system selects Nic 1 to send data packets. 2. Neighbor subsystem (establish neighbor information through arp) When network adapter 1 is selected to send data,

Replace the kernel in ubuntu, and replace the kernel in ubuntu. First download the Linux kernel source code, and store it in the/usr/src directory, here for testing, is in ubuntu14.04, download the kernel is linux-3.14.10 2. Then enter the downloaded kernel linux-3.14.10 r

Linux kernel source code learning: Zombie processes, Linux kernel source code botnets Orphan and botnets After a normal sub-process fork parent process, the two establish a parent-child relationship. When the child process ends, it notifies the parent process, clears the memory occupied by the child process, and leaves its exit information (exit code) in the kernel
