Core API Documentation

This is the beginning of a manual for core kernel APIs. The conversion (and writing!) of documents for this manual is much appreciated!

Core utilities

This section has general and “core core” documentation. The first is a massive grab-bag of kerneldoc info left over from the docbook days; it should really be broken up someday when somebody finds the energy to do it.

Data structures and low-level utilities

Library functionality that is used throughout the kernel.

Low level entry and exit

Concurrency primitives

How Linux keeps everything from happening at the same time. See locking for more related documentation.

Low-level hardware management

Cache management, managing CPU hotplug, etc.

Memory management

How to allocate and use memory in the kernel. Note that there is a lot more memory-management documentation in Linux Memory Management Documentation.

Interfaces for kernel debugging

Everything else

Documents that don’t fit elsewhere or which have yet to be categorized.
