| This is the gem5 simulator. |
| |
| The main website can be found at http://www.gem5.org |
| |
| A good starting point is http://www.gem5.org/about, and for |
| more information about building the simulator and getting started |
| please see http://www.gem5.org/documentation and |
| http://www.gem5.org/documentation/learning_gem5/introduction. |
| |
| To build gem5, you will need the following software: g++ or clang, |
| Python (gem5 links in the Python interpreter), SCons, zlib, m4, and lastly |
| protobuf if you want trace capture and playback support. Please see |
| http://www.gem5.org/documentation/general_docs/building for more details |
| concerning the minimum versions of these tools. |
| |
| Once you have all dependencies resolved, type 'scons |
| build/<CONFIG>/gem5.opt' where CONFIG is one of the options in build_opts like |
| ARM, NULL, MIPS, POWER, SPARC, X86, Garnet_standalone, etc. This will build an |
| optimized version of the gem5 binary (gem5.opt) with the the specified |
| configuration. See http://www.gem5.org/documentation/general_docs/building for |
| more details and options. |
| |
| The main source tree includes these subdirectories: |
| - build_opts: pre-made default configurations for gem5 |
| - build_tools: tools used internally by gem5's build process. |
| - configs: example simulation configuration scripts |
| - ext: less-common external packages needed to build gem5 |
| - include: include files for use in other programs |
| - site_scons: modular components of the build system |
| - src: source code of the gem5 simulator |
| - system: source for some optional system software for simulated systems |
| - tests: regression tests |
| - util: useful utility programs and files |
| |
| To run full-system simulations, you may need compiled system firmware, kernel |
| binaries and one or more disk images, depending on gem5's configuration and |
| what type of workload you're trying to run. Many of those resources can be |
| downloaded from http://resources.gem5.org, and/or from the git repository here: |
| https://gem5.googlesource.com/public/gem5-resources/ |
