I'm not sure what the answer is to many of your questions, but it seems that a good solution to figuring them out would be to just run some simple workloads and then look at the "config.ini" file (default outputted to the m5out directory) to verify your configuration is what you think it is. At first glance, just running "hello world" programs in SE mode would be OK and then you can do some trial/error in the Ruby files to figure out how things work.
Once you are ready for FS mode, check the gem5 page for instructions on getting started there, and then I would say the same process would suffice as well. Start up a simple workload and then toggle configuration parameters to learn how the different things work. And the end of the day, there is no substitute for going through the code itself, so as you do that I would suggest noting helpful "DebugFlags" that are denoted by "DPRINTF" statements. There is documentation on how to use these DebugFlags (TraceFlags) on the gem5 page as well and these will also help you figure out what's going on: ./m5.opt --debug-flags=Ruby configs/example/ruby_se.py 2011/5/17 xuewen zhou <[email protected]> > hello，Gabe ， > I am still another question ： > in DMA_controller.py，there is no port，in RubyController，there is also no > port ，could I add port myself ？ or do something else to get the > DMA_controller‘s > port ？Thank you！ > > 在 2011年5月17日 下午5:48，Gabe Black <[email protected]>写道： > > The best place to see what parameters and ports are on SimObjects is to >> look in the src directory for .py files.
