前置课程是南大ICS的PA实验，jyy的B站空间有他2020年讲的习题课录像供参考。https://nju-projectn.github.io/ics-pa-gitbook/ |

今年不用啦，jyy上课的时候说要把今年的课做成独立的一门 |

如果基础还不错的话 可以直接上手做PA PA的Lab0会介绍环境、生存指南。通过lab0可以初步检验是不是可以直接上手做PA 如果Lab0都看不懂 或者一知半解的话 那么应该补一下基础 |

2025jyy老师已经完全砍掉了oslab实验，只保留了minilab，有一些c语言基础和体系结构基础的应该都可以直接学习了 |

上了很多飞猪推荐的课，但没想到有一天自己在学校上过的课也能出现在这里。jyy确实是国内为数不多地让人眼前一亮的老师，他的课不光利用代码示例、实践等让学生对操作系统的理解不只是停留在概念上，更有很多方法论上的启发，绝对值得认真上完！ |

回复楼上，如果觉得懵逼的话，可以先去做南大的PA，那是前置课程 |

看了操作系统的lab 才知道我们学校的lab属于玩具项目。虽然也是做操作系统子管理 只允许每个人独立完成 平均耗时一个月 不过真的差距蛮大的。 |

如果觉得jyy设计的lab有难度的同学 可以看看实验材料 。如果把实验材料当作索引 按图索骥学习 （这实际上是科研自学的能力）也可以在一定程度上让自己飞速提升。然后再自己给自己设计lab 举个自己的例子：jyy在L5提到了自旋锁 我就用PA中提到的model checking（当然操作系统L4里也说到了）自己分别实现C && 内联汇编&& Java三个版本 然后分别用O2 O1 O0跑model checking 。一天时间就能入门:X86 lock section && memory order && memory coherence |

请问njuos和mit的os 二选一的话 选谁比较好呢 他们内容上有什么区别吗 |
Beta Was this translation helpful? Give feedback.
-
|
对新手来说，xv6是更好的选择，因为网上的博客写的很详细了。而nju的os虽好，但没有一定的工程能力是写不来的，不建议直接写。至于xv6的内容，可以在b站上找哈工深老师的简单入门介绍 |
Beta Was this translation helpful? Give feedback.
-
|
我看介绍上说jyy老师是从很不同的角度讲os的，请问讲的内容和mit有什么差异的地方呢，独特在哪里呢？假设学完xv6还有学习njuos的必要吗？还是以后用到再学就好了阿？ |
Beta Was this translation helpful? Give feedback.
-
|
jyy老师后面也会讲一下xv6，你可以只看课，然后试着写一写nju的lab，写不下去就只看课就好了，可以加q群1028681906看看大家怎么安排 |

miniLab 和 osLab其实都可以在native运行 前提是修改makefile 将arch指向native 且视情况（其实就是make报错文本）来调整makefile和AM的源码 比方说禁止提交远端OJ 事实上校外同学没有token的话 也没必要提交。 但是提交给自己的私有仓库 做必要的源码管理是有意义的 ——jyy多次强调工程化管理 所以我们应该一开始学会用makefile 最后说一下没有OJ做miniLab && osLab还有意义吗？ -------------------分割线-------------------- |

|
您好，请问所有实验都可以本地做和自己做测试案例么？ |
Beta Was this translation helpful? Give feedback.
-
|
可以的 至少我前四个lab都可以在本地native环境编译 编译需要修改makefile 配置必要的libxxx库 修改部分AM Klib代码（tip：测试用例记得回归这些修改过的.c .s文件 可能会炸） |

看课程是用xv6做的core 代码， 但课程上没看到实验环境的搭建的指导， 是我漏掉了吗“？ |

已经学了 2/3 了，非常好的课程，不仅能学到操作系统的知识，重要的是还能了解到许多学习计算机科学的方法论（比如计算机中不存在魔法，一切都是有迹可循的；将程序看作是状态机，程序的执行看作是状态的转换等），个人非常建议每一个从事计算机专业的同学都看一下！ |
