The Linux memory management subsystem is a complex and powerful system, whose main goal is to efficiently manage system memory resources, providing stable and reliable memory allocation and reclamation mechanisms for user-space programs and the kernel itself, while also taking into account the characteristics of different hardware platforms.
1. Overall Architecture of the Memory Management Subsystem
The Linux memory management subsystem is designed with a multi-layer architecture, involving hardware abstraction, physical memory management, virtual memory management, and more.
