android kernel development

according to Luo Shenyang Teacher's "Android system source Scenario analysis" a book, try to download, compile and execute Android source code and kernel source code. But it could be the reason the software source was updated by the wall or version number. Encountered many problems during the period. I turn to the strong degree Niang and Google. The final compila

This section provides a brief introduction to the relevant knowledge points for process scheduling in kernel development. What is process schedulingProcess scheduling is the process of selecting the most appropriate process to execute in a process that is already ready.Process scheduling PolicyReal-time class scheduling strategyScheduling strategies for non-real-time classesTiming of process scheduling

"Some people have the leadership style that leads millions of people in their lives, while others are born to write software that subverts the world. The only one who can do both is Linus Torvalds ." This is what times weekly commented on Linus, the father of Linux. Linus is not only an IT wizards, but also an optimistic and humorous scholar. Next, let the reporter take you to the interview with the father of Linux. Linus Trovalds rarely showed up at meetings, and he was rarely given a speech in

Go to Blog "Ti-davinci Development series of five CCS5.2 using Gdbserver remote Debugging Application"When using CCS5.2 to debug the kernel remotely, you simply import the Linux kernel source code without compiling the kernel, and you won't be using a cross-compilation chain, and you don't need to use gdbserver, but yo

There is a hello World column on it: // Hello. c# Include # Include Module_license ("dual BSD/GPL "); Static int hello_init (void ){Printk (kern_alert "Hello, world/N ");Return 0;} Static void hello_exit (void ){Printk (

I want to participate in the development of the Linux Kernel on the premise that I think I have a strong internal strength. There are two important tasks to do. If I have not touched the kernel source code, I can refer to this article, because almost all open source codes follow this method described in this article. The two jobs are:1. Use git to download the so

Reprint! Adding drivers to the Android kernel is actually adding drivers to the Linux kernel. Mainly in two files add point information, one is the Kconfig file, and the other is a makefile file. For example, you add the driver of your code into the drivers directory under the XXX directory, then repair in the directory of Kconfig files and makefile files.Specifi

Conversely, if the peer is set to mandatory mode, the local side also needs to be set to mandatory, and the force rate is the same as the mandatory rate set on the peer.MAC Module Interface modeMAC modules also have different interfa
