Watch?v=nc qkxznvkg in this installment of source dive , we're deep in the xv6 operating system, trying to understand how physical memory of the system is tracked, distributed, and returned to the kernel.

Understanding Kernel Memory Allocation Using Buddy And Slab Systems The kernel will typically allocate and deallocate multiple types the same data structures over time (e.g. struct task struct) effectively using fixed size allocations. using the slab reduces the frequency of the more heavy allocation deallocation operations. This is a guide to understanding the memory management subsystem of linux. if you are looking for advice on simply allocating memory, see the memory allocation guide. Since the kernel runs critical tasks and needs memory frequently, allocation must be fast, efficient, and minimize fragmentation. common strategies include the buddy system (general purpose block allocation) and the slab system (object based allocation). This blog dives deep into the mechanisms, algorithms, and tradeoffs that power linux memory management. we’ll start with foundational concepts like physical vs. virtual memory, explore core techniques like paging and allocation, and unpack advanced topics like caching and swapping.

This document provides comprehensive coverage of linux kernel memory management from a module author's perspective, including page allocation, slab allocation, virtual memory management, and memory layout analysis.

This blog explores the key challenges, techniques, and modern approaches to kernel memory management, demystifying how operating systems like linux, windows, and freebsd keep systems running smoothly. If a device driver may handle multiple devices (i.e., its probe function can be invoked multiple times), then it needs a way to dynamically allocate memory, once per device instance.
