When CentOS updates the kernel, many startup items will be added during startup. we can delete the old kernel and keep the latest kernel so that some disk space (/boot) can be released ). (1) view the installed kernel command: rpm-qkernel display result: kernel-2.6.32-279.14

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

The Linux kernel module provides a simple introduction to the overall architecture of the Linux kernel, which is already large and includes components or many more. How do we include the required parts in the kernel?One way is to compile all the required functions into the Linux kernel. This can cause two problems. One

Kernel synchronizationSynchronous introductionThe concept of synchronizationCritical section: Also known as the critical segment, is the code snippet that visits and operates shared data.Competition conditions: 2 or more than 2 threads are running at the same time in a critical section, which constitutes a competitive condition.So-called synchronization. In fact, to prevent the formation of competitive conditions in the critical area.Assuming that the
