The current traffic generator relies on a configuration file that
describes a small machine to generate stimuli. This configuration file
is usually generated by the gem5 Python configuration. This creates an
unnecessary and fragile step.
This changeset introduces a Python-based trace module. When
instantiated, the module exposes a start method that takes an iterable
object as a parameter (e.g., a generator). The iterable object is
expected to represent a list of generators that will be run one after
the other. For example:
system.tgen = PyTrafficGen()
m5.instantiate()
def trace():
yield system.tgen.createIdle(1000)
yield system.tgen.createExit(0)
system.tgen.start(trace())
