This makes it possible to specify both an output format (currently, only text is supported) and override default parameters. On the Python-side, this is implemented using a helper function (m5.stats.addStatVisitor) that adds a visitor to the list of active stat visitors. The helper function parses a URL-like stat specification to determine the stat output type. Optional parameters can be specified to change how stat visitors behave. For example, to output stats in text format without stat descriptions: m5.stats.addStatVisitor("text://stats.txt?desc=False") From the command line: gem5.opt --stats-file="text://stats.txt?desc=False" Internally, the stat framework uses the _url_factory decorator to wrap a Python function with the fn(path, **kwargs) signature in a function that takes a parsed URL as its only argument. The path and keyword arguments are automatically derived from the URL in the wrapper function. New output formats can be registered in the m5.stats.factories dictionary. This dictionary contains a mapping between format names (URL schemes) and factory methods. To retain backwards compatibility, the code automatically assumes that the user wants text output if no format has been specified (i.e., when specifying a plain path).
