== Link: Rob Landley's Linux Memory Management Frequently Asked Questions [[Rob Landley's Linux Memory Management Frequently Asked Questions https://landley.net/writing/memory-faq.txt]] is what it says in the title ([[via https://www.reddit.com/r/programming/comments/66rxv4/linux_memory_faq/]]). As of writing this pointer to it, the current version of the FAQ appears to be from 2014, but much of its information is relatively timeless. Landley's FAQ is good for a lot more than Linux specific information. It's a good general overview of a number of hardware {{AB:MMU:Memory Management Unit}} concepts and general Unix MMU concepts. Things like page tables, TLBs, and even memory mappings are basically universal, and the FAQ has a nice solid explanation of all of them and much more.
