This patch updates the FileSystemConfig so it works with more kinds of config scripts (e.g., the Learning gem5 scripts). There are 4 main changes: - Added system as a parameter to the config_filesystem function so the function can search the system for the number of CPUs instead of relying on options from Options.py - Instead of calling redirect_paths everywhere config_filesystem is used, now it is implicitly called. - Cleaned up the Ruby scripts a bit to remove redundant calls to config_filesystem - Added a config_filesystem call to the Ruby Learning gem5 script (currently the only Learning gem5 script that requires it). In the future, I think it would be better to move the config_filesystem call into simulate.py, probably into the instantiate function. I tried to use the per-CPU configuration parameters instead of options from Options.py, but that's not possible until after the SimObject params have been finalized in instantiate.

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/Introduction, and for more information about building the simulator and getting started please see http://www.gem5.org/Documentation and http://www.gem5.org/Tutorials. 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/Dependencies for more details concerning the minimum versions of the aforementioned tools. Once you have all dependencies resolved, type 'scons build/<ARCH>/gem5.opt' where ARCH is one of ALPHA, 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/Build_System for more details and options. With the simulator built, have a look at http://www.gem5.org/Running_gem5 for more information on how to use gem5. 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. Please see the gem5 download page for these items at http://www.gem5.org/Download If you have questions, please send mail to gem5-users@gem5.org Enjoy using gem5 and please share your modifications and extensions.
