README

1It has been said that successful communication requires first identifying
2what your audience knows and then building a bridge from their current
3knowledge to what they need to know.  Unfortunately, the expected
4Linux-kernel memory model (LKMM) audience might be anywhere from novice
5to expert both in kernel hacking and in understanding LKMM.
6
7This document therefore points out a number of places to start reading,
8depending on what you know and what you would like to learn.  Please note
9that the documents later in this list assume that the reader understands
10the material provided by documents earlier in this list.
11
12o	You are new to Linux-kernel concurrency: simple.txt
13
14o	You have some background in Linux-kernel concurrency, and would
15	like an overview of the types of low-level concurrency primitives
16	that the Linux kernel provides:  ordering.txt
17
18	Here, "low level" means atomic operations to single variables.
19
20o	You are familiar with the Linux-kernel concurrency primitives
21	that you need, and just want to get started with LKMM litmus
22	tests:  litmus-tests.txt
23
24o	You are familiar with Linux-kernel concurrency, and would
25	like a detailed intuitive understanding of LKMM, including
26	situations involving more than two threads:  recipes.txt
27
28o	You would like a detailed understanding of what your compiler can
29	and cannot do to control dependencies:  control-dependencies.txt
30
31o	You are familiar with Linux-kernel concurrency and the use of
32	LKMM, and would like a quick reference:  cheatsheet.txt
33
34o	You are familiar with Linux-kernel concurrency and the use
35	of LKMM, and would like to learn about LKMM's requirements,
36	rationale, and implementation:	explanation.txt
37
38o	You are interested in the publications related to LKMM, including
39	hardware manuals, academic literature, standards-committee
40	working papers, and LWN articles:  references.txt
