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, SWIG, 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 the aforementioned tools.
Once you have all dependencies resolved, type 'scons build//gem5.opt' where ARCH is one of ARM, NULL, MIPS, POWER, SPARC, or X86. This will build an optimized version of the gem5 binary (gem5.opt) for the the specified architecture. See http://www.gem5.org/documentation/general_docs/building for more details and options.
The basic source release includes these subdirectories:
- configs: example simulation configuration scripts
- ext: less-common external packages needed to build gem5
- 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 will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images.
If you have questions, please send mail to gem5-users@gem5.org
Enjoy using gem5 and please share your modifications and extensions.
首先，使用如下命令clone该仓库
git clone https://github.com/Raymondwo/gem5-src.git
然后，在stable分支的基础上，创建自己的分支。
git checkout stable
git checkout -b ray-mybranch
修改本地文件，例如readme。
git add readme
git commmit -m "modify the readme file"
上传本地分支到远程。
git push --set-upstream origin ray-mybranch
所有ray创建的分支将使用ray作为开头。首先，大家创建一个自己的master分支，然后在该分支的基础上创建tutorial分支等。
