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 h

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. lsmod uses this file as well. Entries in/proc/mod
