For now, the Python emits a .ini file that can be 743101Sstever@eecs.umich.edu# parsed by M5. In the future, some tighter integration between M5 754762Snate@binkert.org# and the Python interpreter may allow bypassing the .ini file. 764762Snate@binkert.org# 774762Snate@binkert.org# Each SimObject class in M5 is represented by a Python class with the 784762Snate@binkert.org# same name. The Python inheritance tree mirrors the M5 C++ tree 794762Snate@binkert.org# (e.g., SimpleCPU derives from BaseCPU in both cases, and all 804762Snate@binkert.org# SimObjects inherit from a single SimObject base class). To specify 814762Snate@binkert.org# an instance of an M5 SimObject in a configuration, the user simply 824762Snate@binkert.org# instantiates the corresponding Python object. The parameters for 834762Snate@binkert.org# that SimObject are given by assigning to attributes of the Python 845033Smilesck@eecs.umich.edu# object, either using keyword assignment in the constructor or in 855033Smilesck@eecs.umich.edu# separate assignment statements. For example: 865033Smilesck@eecs.umich.edu# 875033Smilesck@eecs.umich.edu# cache = BaseCache(size='64KB') 885033Smilesck@eecs.umich.edu# cache.hit_latency = 3 895033Smilesck@eecs.umich.edu# cache.assoc = 8 905033Smilesck@eecs.umich.edu# 915033Smilesck@eecs.umich.edu# The magic lies in the mapping of the Python attributes for SimObject 925033Smilesck@eecs.umich.edu# classes to the actual SimObject parameter specifications. This 935033Smilesck@eecs.umich.edu# allows parameter validity checking in the Python code. Continuing 943101Sstever@eecs.umich.edu# the example above, the statements "cache.blurfl=3" or 953101Sstever@eecs.umich.edu# "cache.assoc='hello'" would both result in runtime errors in Python, 963101Sstever@eecs.umich.edu# since the BaseCache object has no 'blurfl' parameter and the 'assoc' 975033Smilesck@eecs.umich.edu# parameter requires an integer, respectively. This magic is done 9810267SGeoffrey.Blake@arm.com# primarily by overriding the special __setattr__ method that controls 998596Ssteve.reinhardt@amd.com# assignment to object attributes. 1008596Ssteve.reinhardt@amd.com# 1018596Ssteve.reinhardt@amd.com# Once a set of Python objects have been instantiated in a hierarchy, 1028596Ssteve.reinhardt@amd.com# calling 'instantiate(obj)' (where obj is the root of the hierarchy) 1037673Snate@binkert.org# will generate a .ini file. 1047673Snate@binkert.org# 1057673Snate@binkert.org##################################################################### 1067673Snate@binkert.org 10711988Sandreas.sandberg@arm.com# list of all SimObject classes 10811988Sandreas.sandberg@arm.comallClasses = {} 10911988Sandreas.sandberg@arm.com 11011988Sandreas.sandberg@arm.com# dict to look up SimObjects based on path 1113101Sstever@eecs.umich.eduinstanceDict = {} 1123101Sstever@eecs.umich.edu 1133101Sstever@eecs.umich.edudef public_value(key, value): 1143101Sstever@eecs.umich.edu return key.startswith('_') or \ 1153101Sstever@eecs.umich.edu isinstance(value, (FunctionType, MethodType, ModuleType, 11610380SAndrew.Bardsley@arm.com classmethod, type)) 11710380SAndrew.Bardsley@arm.com 11810380SAndrew.Bardsley@arm.com# The metaclass for SimObject.
