Most of the test cases currently contain a large amount of duplicated
boiler plate code. This changeset introduces a set of classes that
encapsulates most of the functionality when setting up a test
configuration.
The following base classes are introduced:
* BaseSystem - Basic system configuration that can be used for both
SE and FS simulation.
* BaseFSSystem - Basic FS configuration uni-processor and multi-processor
configurations.
* BaseFSSystemUniprocessor - Basic FS configuration for uni-processor
configurations. This is provided as a way
to make existing test cases backwards
compatible.
Architecture specific implementations are provided for ARM, Alpha, and
X86.
This is the gem5 simulator.
For detailed information about building the simulator and getting
started please refer to:

Short version:
External tools and required versions
To build gem5, you will need the following software:
g++ version 4.3 or newer.
Python, version 2.4 - 2.7 (we don't support Python 3.X). gem5 links in the
Python interpreter, so you need the Python header files and shared
library (e.g., /usr/lib/libpython2.4.so) in addition to the interpreter
executable. These may or may not be installed by default. For example,
on Debian/Ubuntu, you need the "python-dev" package in addition to the
"python" package. If you need a newer or different Python installation
but can't or don't want to upgrade the default Python on your system,
see http://www.gem5.org/Using_a_non-default_Python_installation
SCons, version 0.98.1 or newer. SCons is a powerful replacement for make.
If you don't have administrator privileges on your machine, you can use the
"scons-local" package to install scons in your m5 directory, or install SCons
in your home directory using the '--prefix=' option.
SWIG, version 1.3.34 or newer
zlib, any recent version. For Debian/Ubuntu, you will need the "zlib-dev" or
"zlib1g-dev" package to get the zlib.h header file as well as the library
itself.
m4, the macro processor.
4. In this directory, type 'scons build/<ARCH>/gem5.opt' where ARCH is one
of ALPHA, ARM, MIPS, POWER, SPARC, or X86. This will build an optimized version
of the gem5 binary (gem5.opt) for the the specified architecture.

WHAT'S INCLUDED (AND NOT)
-------------------------
The basic source release includes these subdirectories:
- gem5:
- 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.
