Introduction to the Linux kernel module the overall structure of the Linux kernel is already very large, and it contains many components. How can we include all the required parts in the kernel?One way is to compile all required functions into the Linux kernel. This will cause two problems. One is that the generated

Linux0.11 Kernel Analysis-kernel architecture and linux0.11 Architecture A complete and available operating system consists of four parts: hardware, operating system kernel, operating system services, and user applications, as shown in: User applications refer to the word processing programs, Internet browser programs, or various applications compiled by the user

Most Linux instances are single-coreThe operating system kernel may be a micro kernel or a single kernel (which is sometimes called a macro kernel macrokernel ). These terms are defined as follows in a similar encapsulation:L microkernel (microkernel)-In the microkernel, most kernels run as separate processes in a priv
