The startup optimizations for Android are divided into three main parts:(1) bootloader optimization(2) Tailoring and optimization of Linux kernel(3) Tailoring and optimization of Android OS partsThis article focuses on the start-up optimization of the Android OS section, and the noteworthy optimization points are descr

Article Title: Linux kernel module for Driver Programming. 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. Linux device drivers are part of the kernel. A Linux

Android kernel compilation method embedded online { Favorites (); } "Href =" javascript:; "> Add-to-favorites | many Google Android users want to transplant it to the relevant hardware platform before gphone is released. I read a lot of articles on the Internet. The general feeling is that the farthest step in this step is the master hacker Ben "Benno" Leslie of

maintain source code consistency, we need to add definitions such as # ifdef, you can use Linux/utsrelease. uts_relese, liux/version under H. linux_version_code or kernel_version under H. The latter two convert their values to the hexadecimal format of 0x.. We only talk about source code consistency. We still need to specify different kdir for compilation. In this case, according to our programming philosophy, we use the macro to specify the low-leve

1. the UNIX tradition of the I/O buffer of the C standard library is everything is a file, the keyboard, display, serial port, disk, and other devices have a special device file in the/dev directory, these device files can be opened, read, written, and closed just like normal files (files stored on disks). The function interfaces are the same. User Programs call C standard I/O library functions to read and write common files or devices. These library functions send read and write requests to the

Linux Kernel programming (character device file)-General Linux technology-Linux programming and kernel information. The following is a detailed description. Now we are original-level kernel programmers who know how to write kernel

Summary Linux Kernel module programming materials are complicated, some are too simple, some are too complex, I try to use the form of notes to show readers how to process LINUX module programming, trying to make it simpleClearly, this article is also a piece of information I have forgotten, so it is inevitable that it is too simple in some places. The purpose of

1. What is a kernel object? The kernel object is a memory block allocated by the operating system. The memory block is a data structure used to manage various object information. When the application needs to interact with the system device, it will use the kernel object. For security reasons, the process cannot directly access the

The simplest way to improve hardware performance is to add multiple CPUs to the motherboard (reading is the cheapest way ). Either let different CPUs do
