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¶

Entry/exit handling for exceptions, interrupts, syscalls and KVM

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 Memory Management Documentation.

Interfaces for kernel debugging¶

Everything else¶

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