From f065f9941b5e3b2796ec46d1926115283edd66cd Mon Sep 17 00:00:00 2001 From: Jason Lowe-Power Date: Wed, 16 Sep 2015 09:35:36 -0500 Subject: config: Add configs scripts used in Learning gem5 Added a new directory in configs (learning_gem5) to hold the scripts that are used in the book. See http://lowepower.com/jason/learning_gem5/ for a working copy. For now, only the scripts in Part 1: Getting started with gem5 have been added. A separate patch adds tests for these scripts.
