Understanding x86-64 Memory Paging Mechanism and Its Implementation

This article explains the role, operation, and different modes of x86‑64 memory paging, describes how page directories and tables are set up in assembly, shows the relevant control‑register bits, and provides practical code examples for enabling and managing paging in a protected‑mode kernel.

Understanding Memory Paging and Page Table Structures in x86-64

Memory paging, a core memory‑management technique used in modern operating systems and x86‑64 processors, divides physical memory into fixed‑size pages, enabling virtual memory, isolation, sharing, lazy loading, and protection, while the article explains page tables, hierarchical paging modes, and provides assembly code for enabling paging.
