1. Why should we learn the kernel? Some people want to learn the kernel, while others do not. If you want to engage in system development or driver development in the future, you must learn the kernel. I just got started with the kernel and mainly learned kernel interface fu

Although China Telecom is closely connected with computers, the author can only be considered as an amateur computer enthusiast. Therefore, we should say that the book "full note" is a description from the perspective of a computer layman.LinuxOperating system kernel. The book is relatively small.

Programs running in the Linux kernel should always prevent competing states caused by concurrency. This will cause the data structure to be broken down and cause the kernel to crash in severe cases. Therefore, the kernel synchronization technology is very important to the driver developed by the

, the kernel defines a set of standard APIs, the application if a set of API interface can be used to invoke the kernel through this API interface, if not satisfied, the kernel will ignore, for security reasons, Otherwise the application can simply call the kernel, it is not finished, so if you learn application progra

I. Linux configuration and compilation Linux has the following advantages: 1. Clear temporary files, intermediate files, and configuration files (1) make clean: delete most of the generated files, but keep the configuration file (2) Make mrproper: delete all generated files and configuration files (3) make distclean: Delete the patch and backup files of the editor based on make mrproper. 2.

corresponding __attribute__ parameters in parentheses.The syntax format is: __attribute__ ((attribute-list))Attribute sections are used for functions and variables, and typically the compiler places functions in the. Text section, where variables are placed in the. data or. BSS sections, and the section property allows the compiler to place functions or variables in the specified section.2, meaning of Is_err () in driverAll drivers are running in kernel
