Linux version number: Linux 2.6 2---> Major version number 6----> Minor version number: Odd for test version even for stable version This article uses the kernel version of linux3.14 3.

Today is Laba Festival, said the woman ticket to give me to do the Laba porridge is so bad, so sad, good-hearted acid ah, it seems that the code is really annoying drops, so I warned you technical male wake alarm, do not want me to the same, or you can only and the Code as companion ~ ~ said no Laba porridge but there is code, and you have the support of readers , so you have to continue to write down, calm down, complete the Linux kernel learning, ad

One pageThe kernel takes the physical page as the basic unit of memory management; the Memory Management Unit (MMU) transforms the virtual address into a physicalAddresses, which are typically processed in pages. The MMU manages the tables in the system in the page size unit.32-bit system: Page size 4KB64-bit system: Page size 8KBThe kernel represents each physical page in the system with the corresponding

In the Linux Kernel (Android) Cryptographic algorithm summary (cipher, Compress, Digest) article, it describes how to include three different types of kernel encryption algorithms in the kernel, and gives examples of how to invoke them in kernel modules.This article will focus on how to invoke the cryptographic algorit

The kernel often needs to execute some operations in the background. This task can be completed through the kernel thread-a standard process that runs independently in the kernel space. The difference between a kernel thread and a common process is that the kernel thread doe

This semester the Linux kernel experiment is the final Print kernel page table, linear address----physical AddressWhen I saw this experiment, I thought of this init function (because that's what I was talking about at the time), which is the ^_^ of the Linux kernel page table, which is the mapping of 896M linear addresses above 3G in 32-bit systems to the 0-896m

Linus discusses the relationship between kernel header files and kernel source code-Linux general technology-Linux programming and kernel information. The following is a detailed description.

Article title: Kernel 2.6 does not compile the kernel to add modules to iptables. 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. install the kernel source code. 　　 [Root @ ji

First, let's introduce the general process of creating a thread: In the initialization function of the module, call netlink_kernel_create to register its own netlink protocol, and return the result. The function that receives the netlink message is fcluster_netlink_recv, the actual initialization operation is performed only after the netlink message is received. The thread creation operation is also performed in fcluster_netlink_recv, as shown in: the statement for calling kernel_thread is: [cpp

This article is mostly reproduced and assembled, just think that these knowledge should be put together better. How process system resources are usedMost processes request memory using GLIBC, but GLIBC is also an application library that ultimately calls the operating system's memory management interface to use memory. In most cases, the glibc is transparent to the user and the operating system, so it is very helpful to observe the process logged by the operating system directly to the memory us

The kernel provides several ways to prevent competitive conditions, and understanding the usage scenarios of these methods helps us to choose the appropriate synchronization method when writing kernel code.This ensures the security of critical sections in your code, while minimizing the loss of performance.Main content: Atomic operation Spin lock Read/write Spin lock Signal Volume R
