Some articles have already introduced the android kernel. This series will analyze the android kernel from the perspective of the Linux kernel, hoping to provide useful information for beginners. This chapter briefly introduces the full picture of the android kernel and plays an interesting role. Starting from the next

Linux kernel:Kernel design Genre:Single core design, but fully learn the advantages of micro-kernel system design, for the kernel introduced a modular mechanism, the core height of modularity;After the kernel is modularized, some of the most basic and important content is compiled into kernel core, while other function

Linux Kernel Design and Implementation of Reading Notes, Linux Kernel Chapter 3 Process Management 1. fork system calls are returned twice from the kernel: one is returned to the sub-process and one is returned to the parent process. the task_struct structure is allocated by the slab distributor. 2.6 was previously placed at the bottom of the stack of the

How to patch the Linux kernel -------------------- Author: Jesper juhl,2005 year August Date Last updated: 2006-01-05 Translator: Jeffshia, August 2006 Email: Tshxiayu@126.com One of the frequently asked questions in the Linux kernel mailing list is how to make a patch for the Linux kernel, or, more specifically, There are so many backbones/branches, a patch in

Programs running in the Linux kernel should always prevent competing states caused by concurrency. This will cause the data structure to be broken down and cause the kernel to crash in severe cases. Therefore, the kernel synchronization technology is very important to the driver developed by the kernel. People who do n

Introduction to the Linux kernel module the overall structure of the Linux kernel is already very large, and it contains many components. How can we include all the required parts in the kernel?One way is to compile all required functions into the Linux kernel. This will cause two problems. One is that the generated

RefHttp://www.zhizhihu.com/html/y2010/2292.htmlKernel FunctionsBelow is a list of some kernel functions available from the existing literature. As is the case with previous articles, every LaTeX notation for the formulas below is readily available from their A Lternate text HTML tag. I can not guarantee all of them is perfectly correct, thus use them at your own risk. The most of them has links to articles where they has been originally used or propos

Linux Kernel compilation details, Linux kernel details After learning some online materials, I tried to find out and sort out this article. We hope you will criticize and correct the mistakes due to their limited level and improper position.

Data exchange between linux kernel and user layer and linux Kernel 1. There are basically System Call interfaces file_operation interfaces: read write ioctl? Module param of module driver (module parameters of module driver ). 2. kernel startup parameters :?By identifying the parameters passed by bootloader?_ Setup ("para_name =", parse_func) 3. asynchronous no

The Linux kernel module provides a simple introduction to the overall architecture of the Linux kernel, which is already large and includes components or many more. How do we include the required parts in the kernel?One way is to compile all the required functions into the Linux kernel. This can cause two problems. One

Most Linux instances are single-coreThe operating system kernel may be a micro kernel or a single kernel (which is sometimes called a macro kernel macrokernel ). These terms are defined as follows in a similar encapsulation:L microkernel (microkernel)-In the microkernel, most kernels run as separate processes in a priv

Chapter One: Introduction to the Kernel The scope of the processor's activity at any given point in time: A, run in the kernel space, in the process context, on behalf of a specific process execution; b, running in kernel space, in the interrupt context, regardless of any process, handling a particular interrupt; C, run in user space, execute user process. When a
