I. Kernel configuration and compilation of the Development Board 1. decompress the kernel package and copy the smdk6410_config Kernel configuration file to. config (default configuration file) to the kernel source code tree. Generally, the platform configuration file is stor

From Linux kernel monkey log | translated by Li Yun. For more information, see the ifanr translation link. Version 2.6.33 removed andirod's code from the kernel. Many people keep asking me what happened and what to do next for Android. Here is my clarification on the whole thing: First, I like the Android platform very

I Build Android Kernel (with Module enabled)1. Kernel source is under Android_src/kernel folder2. Config file is under kernel_src/arch/arm/configs folder Xxx_deconfig3. Setup Config:$make Arch=arm Cross_compile=arm-eabi-xxx_defconfig(. config file can also is created from device:ADB pull proc/config.gzZcat config.gz >.

Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired. Spec

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 foc

Measurement of the time differenceThe system's timer hardware generates a clock interrupt at a fixed frequency, producing a constant interrupt interval determined by Hz constants, usually between 50~1200, x86 by default 1000,hz can be configured according to different cores.Linux uses jiffies (unsigned long) to count clock interrupts, and the value of Jiffies is 1 when a clock interrupt occurs, so Jiffies records the total number of clock interrupts since the system was powered on. Clock interru

Loader to do two things, let's start with the first item, load the kernel into memory:1. Load the kernel into memory.2. Jump into protected mode.When you first compile a no-kernel:NASM Boot.asm-o Boot.binNASM Loader.asm-o Loader.binDD if=boot.bin of=a.img bs=512 count=1 conv=notruncsudo mount-o loop a.img/mnt/hgfs/sudo cp loader.bin/mnt/hgfs/-Vsudo umount/mnt/hgfs/The results of the operation are as follows
