| <p>This is an intro to this tutorial. It says lots of interesting things.</p> |
| |
| <p>The goal of this document is to give you, the reader, a thorough |
| introduction on how to use gem5 and the gem5 codebase. The purpose of |
| this document is not to provide a detailed description of every feature |
| in gem5. After reading this document, you should feel comfortable using |
| gem5 in the classroom and for computer architecture research. |
| Additionally, you should be able to modify and extend gem5 and then |
| contribute your improvements to the main gem5 repository.</p> |
| |
| <p>This document is colored by my personal experiences with gem5 over the |
| past six years as a graduate student at the University of |
| Wisconsin-Madison. The examples presented are just one way to do it. |
| Unlike Python, whose mantra is “There should be one– and preferably |
| only one –obvious way to do it.” (from The Zen of Python. See |
| <code class="highlighter-rouge">import this</code>), in gem5 there are a number of different ways to |
| accomplish the same thing. Thus, many of the examples presented in this |
| book are my opinion of the best way to do things.</p> |
| |
| <p>One important lesson I have learned (the hard way) is when using complex |
| tools like gem5, it is important to actually understand how it works |
| before using it.</p> |
| |
| <p>Finish the previous paragraph about how it is a good idea to understand |
| what your tools are actually doing.</p> |
| |
| <p>should add a list of terms. Things like “simulated system” vs “host |
| system”, etc.</p> |
