This commit makes it possible to make invocations such as: gem5.opt se.py --stats-root 'system.cpu[:].dtb' --stats-root 'system.membus' When --stats-root is given, only stats that are under any of the root SimObjects get dumped. E.g. the above invocation would dump stats such as: system.cpu0.dtb.walker.pwrStateResidencyTicks::UNDEFINED system.cpu1.dtb.walker.pwrStateResidencyTicks::UNDEFINED system.membus.pwrStateResidencyTicks::UNDEFINED system.membus.trans_dist::ReadReq but not for example `system.clk_domain.clock`. If the --stats-root is given, only new stats as defined at: Idc8ff448b9f70a796427b4a5231e7371485130b4 get dumped, and old ones are ignored. The commits following that one have done some initial conversion work, but many stats are still in the old format.

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/<ARCH>/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.
