2.2 Windows driver development: kernel spin lock structure
When it comes to spin locks, we must talk about linked lists. In the previous article “Linked Lists and Structures in the Kernel”, we simply used the linked list structure to store the process information list. I believe readers should have understood it. The basic use of kernel linked lists. This article will explain the […]
Implement personal mobile phone location analysis based on Python! I just want to ask you if you can hang it!
TransBigData is a Python package developed for traffic spatiotemporal big data processing, analysis, and visualization. This article will use it to implement personal mobile phone positioning analysis But in fact, traffic spatio-temporal big data is not limited to the data generated by transportation vehicles. A large amount of data is also generated in our daily […]

Lab8: Locks | Lock optimization implementation
Lab: locks Memory allocator (moderate) Your job is to implement per-CPU freelists, and stealing when a CPU’s free list is empty. You must give all of your locks names that start with “kmem”. That is, you should call initlock for each of your locks, and pass a name that starts with “kmem”. Run kalloctest to […]
