55# M5 Python Configuration Utility
56#
57# The basic idea is to write simple Python programs that build Python
58# objects corresponding to M5 SimObjects for the desired simulation
59# configuration. For now, the Python emits a .ini file that can be
60# parsed by M5. In the future, some tighter integration between M5
61# and the Python interpreter may allow bypassing the .ini file.
62#
63# Each SimObject class in M5 is represented by a Python class with the
64# same name. The Python inheritance tree mirrors the M5 C++ tree
65# (e.g., SimpleCPU derives from BaseCPU in both cases, and all
66# SimObjects inherit from a single SimObject base class). To specify
67# an instance of an M5 SimObject in a configuration, the user simply
68# instantiates the corresponding Python object. The parameters for
69# that SimObject are given by assigning to attributes of the Python
70# object, either using keyword assignment in the constructor or in
71# separate assignment statements. For example:
72#
73# cache = BaseCache(size='64KB')
74# cache.hit_latency = 3
75# cache.assoc = 8
76#
77# The magic lies in the mapping of the Python attributes for SimObject
78# classes to the actual SimObject parameter specifications. This
79# allows parameter validity checking in the Python code. Continuing
80# the example above, the statements "cache.blurfl=3" or
81# "cache.assoc='hello'" would both result in runtime errors in Python,
82# since the BaseCache object has no 'blurfl' parameter and the 'assoc'
83# parameter requires an integer, respectively. This magic is done
84# primarily by overriding the special __setattr__ method that controls
85# assignment to object attributes.
86#
87# Once a set of Python objects have been instantiated in a hierarchy,
88# calling 'instantiate(obj)' (where obj is the root of the hierarchy)
89# will generate a .ini file.
