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