such as process descriptors. But in other ways they are mature kernel-level code that, if needed, can always be compiled into the kernel (so that all restrictions can be bypassed). Fully developing and compiling linux source code tree module (This is expected to be called a Tree build), which is very handy if you just want to play and don't want to c

It was just a day, and I studied how to compile Linux kernel in my spare time. I used to work on Windows platforms and almost never used Linux, so I wanted to have a good time. The platform is the latest Ubuntu 10.04 LTS, and the kernel is also the latest version 2.6.35.2 downloaded. In fact,

command as the root user: % make modules_install This command will install all the compiled modules in the corresponding sub-directories under/lib/modules. The generation process creates a System under the root directory of the source code. the map file contains a symbolic lookup table that maps the kernel symbols to their starting addresses. During debugging, you can use it to convert the memory addresses

Do you want to know how to become a Linux kernel developer? Or your boss tells you, "Write a Linux driver for this device. "The purpose of this document is to describe the process you need to go through and instruct you how to work with the community to teach you all the knowledge you need to know for these purposes. This article also explains why the community w

The main way to identify and resolve program errors on LinuxYou can monitor a running user-space program in a variety of ways: You can run the debugger for it, step through the program, add a print statement, or add tools to parse the program. This article describes several methods that you can use to debug programs that run on Linux. We'll review four debugging problems, including segment errors, memory ov

First, let's talk about how this problem came about. (When analyzing a technology, we should first consider what problems it wants to solve, or when learning new knowledge, what is the purpose of this knowledge ). When compiling the kernel, I found a file named vmlinux. LDS. s under the arch/ARM/kernel directory. At first glance, do you want to compile a file? It seems that it is not. So what does it do?

Management is the management of process control blocks. Linux processes are generated by calling the fork () function system. The process that calls fork () is called the parent process, and the generated process is called the child process. When a child process is created, the data structure except the process ID is exactly the same as that of the parent process. After the fork () System Call creates the memory, the sub-process is immediately added

the service, write () is not used, then we can not implement it. Then create a device file in the/dev/directory corresponding to our newly added kernel system call log system driver.C: Using the proc file systemProc is a special file system provided by Linux, and its purpose is to provide a convenient way to interact between users and the kernel. It uses the fil
