The previous slower ruby latencies created a mismatch between the faster M5
cpu models and the much slower ruby memory system. Specifically smp
interrupts were much slower and infrequent, as well as cpus moving in and out
of spin locks. The result was many cpus were idle for large periods of time.
These changes fix the latency mismatch.
Reorganized ruby python configuration so that protocol and ruby memory system
configuration code can be shared by multiple front-end configuration files
(i.e. memory tester, full system, and hopefully the regression tester). This
code works for memory tester, but have not tested fs mode.
-option to allow threads to run to a max_inst_any_thread which is more useful/quicker in a lot of
cases then always having to figure out what tick to run your simulation to.
this was double scheduling itself (once in constructor and once in cpu code). also add support for stopping / starting
progress events through repeatEvent flag and also changing the interval of the progress event as well
configs/common/Options.py:
make the warmup period in a standard switch part of the option.
configs/common/Simulation.py:
add some comments and also make the warmup period an option.
