This lesson is mainly to explain how to learn Linux and learning the attitude and thinking of Linux, so that we have a general framework for learning to learn Linux in the future lay the foundation.This article is from the Linux learners blog, so be sure to keep this source http://wiliiwin.blog.51cto.com/928128/1640204
When reading the Linux kernel source code or performing performance optimizations on the codes, there is often a need to embed a piece of assembler code in the C language, which is called inline assembly in CS terminology. The notes in this article attempt to illustrate the basic grammatical rules and usages of inline assembly (students with strong English reading skills are advised to read the technical articles recommended in this reference directly
