This article explains Linux's process memory layout, allocation mechanisms, out‑of‑memory handling, where different types of memory reside, and both manual and automatic memory reclamation techniques, providing practical examples and kernel‑level insights for developers and system engineers.
This article explores memory management concepts from both operating system and MySQL perspectives, covering virtual vs physical memory, process memory usage analysis using tools like top and /proc, and experimental verification of memory allocation behaviors.
The article explains Linux kernel virtual memory management on 64‑bit ARM64 Android systems, detailing user‑ and kernel‑space address layout, physical vs. linear addresses, allocation mechanisms such as brk and mmap, common allocators, key structures like mm_struct and vm_area_struct, and the functions that control mmap layout and unmapped‑area selection.
This article explains how a running program's code and variables are organized in Linux memory, covering virtual address mapping, the purpose of each segment (text, rodata, data, bss, stack, heap), and demonstrates the concepts with concrete C examples and memory‑map screenshots.
