For more information, see "learn while doing" by Zhejiang University Press.Chapter 9 Linux kernel compilation experiment objective: to learn how to re-compile the Linux kernel and understand the differences between the Linux standard kernel and the released version. experiment content: compiling the Linux kernel is an
How can we compile the kernel module before? Describes how to compile modules. Here, we will continue to introduce how to compile kernel modules in the 2.6 kernel. The method for compiling the kernel module is slightly different from that for compiling general applications. makefile exists in the directory of the
Sleep a good sleep, very late, for a long time not so comfortable, today's task is not heavy, so the pressure is not big, oh, the weather is really cold, but the laboratory has air conditioning, I still like to stay here, there is a different feeling, after writing so many days, I do not understand the page gradually enlightened, And also made some friends, really very happy ah. Today will introduce you to add code to the kernel, take a look at it ~Fi

Unix has a history of 40, but computer scientists still regard it as the largest and most outstanding System in the existing operating system. It has become a legend and remains well known after time.
In 1973, after the Unix system was rewritten in C language, a large number of Unix-de

TodaySo many servers and workstations around us run linux, so many friends want to understand the core mechanism of linux. However, as the kernel is too large, some friends are discouraged. (I also had this experience when I was in my sophomore year. When I saw some people watching
I. Description of BOOTM
BOOTM This command is used to start an operating system image. It obtains some information from the head of the image file, which includes the CPU architecture of the image file, its operating system type, the type of image, the compression method, the load address of the image file in memory, the entry address of the image file to run, the image filename, and so on.The BOOTM then loads the image to the specified address and, if necessary, extracts the image and passes t
