Linux’s Virtual Memory Area (VMA) is the kernel’s core structure for managing a process’s address space, and this article explains its definition, key fields, linked‑list and red‑black‑tree organization, allocation, protection, page‑fault handling, copy‑on‑write, and practical usage examples.
This article explains the Linux kernel's heap memory allocation process, covering the vm_area_struct and mm_struct data structures, the brk system call implementation, and the page‑fault handling that maps virtual addresses to physical memory, while also mentioning other allocation mechanisms such as mmap and HugePages.
This article explains Linux process memory organization, detailing how task_struct and mm_struct describe virtual memory, the role of vm_area_struct for each segment, page table interactions, and the lazy allocation mechanism that maps physical memory only on page faults.
