This directory contains files associated with the book Understanding Software
Dynamics by Richard L. Sites, ISBN 978-0137589739.

The book-figures directory contains the underlying HTML files for over 100 of
the diagrams in the book, so you can wander around them to see more context or
to discover other performance issues.

The book-user-code directory contains all the programs used in the book and the
script to compile them. They compile and run on both x86 and Rpi4 machines.

The hello_world_trace.html file is an example trace of the hello_world_trace.c
program found in book-user-code.

The kutrace_uder_guide.pdf file gives more detial and is more recent than the
text in Chapter 19 of the book.

The linux_patches_installation_guide.pdf gives brief directions for building
the patches.

The loadable-module directory contains the source and Makefile for the companion
kernel module that implements the bulk of KUtrace. It builds for AMD and Intel
x86 machines and for the Raspberry Pi4-B.

The patches-* files contain original source and patched source pairs of files
for adding KUtrace to three different versions of the Linux operating system.
These files are structured in the matching directories of the original Linux
source download. The patches-linux-5.10.46-rpi4 folder contains additional
documentation and useful scripts for building a patched kernel for any of
these three versions or for incorporating the patches into other versions. Only
64-bit versions of Linux are supported in this code; 32-bit ports of KUtrace
are possible but difficult.

All the code is open sourced under the BSD three-clause license.
