如何互斥和锁定结构来实现？ [英] How are mutex and lock structures implemented?

问题描述

我明白了锁，互斥和其他同步结构的概念，但他们是如何实现的？它们是由OS提供，或者是这些结构依赖于特殊的CPU指令的CPU的MMU的？

I understand the concept of locks, mutex and other synchronization structures, but how are they implemented? Are they provided by the OS, or are these structures dependent on special CPU instructions for the CPUs MMU?
