Introduction
Unknown device, no longer headache!
Rule 1: do not lose the drive disc of the device.
Rule 2: exercise caution when saving a backup.
Rule 3: If your driver file is lost, you need to know where to download it.
Congratulations! If you do not care about the above two items, this article can
Many Linux application developers and Linux Device Driver developers are excited and excited in the face of constantly upgrading linux kernels, GNU development tools, and various graphic libraries in Linux environments. I am excited that new software and tools provide me with more powerful functions. It is very tedious to adapt to the features of new software and build a new environment. This article will discuss how to learn Linux

It may be difficult to put the driver model in the first chapter, but as long as the driver model can be crossed, it will be much easier later. The driver model is the cornerstone of the entire Linux Device Driver. Most people call the driver model a device model, but I have checked the help document of Linux to find the driver-model directory in the documentation directory under the

Chapter 1 2: An Introduction to device driver building and running modules
1. Concurrent, security -- module writting notes
2. Kernel stack is small, normally one page (4 K). So don't create a lot of local variables and don't have a long call stack.
3. kernel can't handle float pointing computing.
4. Compiling Build:
OBJ-M: = module. o
Module-objs: = file1.o file2.o
Make-C ~ /Kernel-2.6 m = 'pwd' modules
5./proc/modules saves all modules load. lsmo
Here we will introduce the solution to the Linux Device Driver problem. The basic operation of Linux to be added to the 3ed scull module of Linux driver compiled by ora 7 is designed to give readers a preliminary understanding of Linux. Content involves file management, disk management, user and group management, man help, software package management, File compression, and printer management.

So let's take a look at where the Skb_release_data starts:#grep Skb_release_data./system.mapC0282AF4 T Skb_release_dataSo we know that when the system error occurs, the program pointer is c0282af4+0x74=c0282b68(2) Then use GDB to view the GDB./vmlinux (executed under the Linux directory) and enter debug mode.gdb$ b *0xc0282b68Breakpoint 1 at 0xc0282b68:file NET/CORE/SKBUFF.C, line312This is to tell us in which file, in
