For now, the Python emits a .ini file that can be 61679SN/A# parsed by M5. In the future, some tighter integration between M5 62679SN/A# and the Python interpreter may allow bypassing the .ini file. 63679SN/A# 64679SN/A# Each SimObject class in M5 is represented by a Python class with the 65679SN/A# same name. The Python inheritance tree mirrors the M5 C++ tree 66679SN/A# (e.g., SimpleCPU derives from BaseCPU in both cases, and all 67679SN/A# SimObjects inherit from a single SimObject base class). To specify 68679SN/A# an instance of an M5 SimObject in a configuration, the user simply 69679SN/A# instantiates the corresponding Python object. The parameters for 70679SN/A# that SimObject are given by assigning to attributes of the Python 71679SN/A# object, either using keyword assignment in the constructor or in 72679SN/A# separate assignment statements. For example: 73679SN/A# 741692SN/A# cache = BaseCache(size='64KB') 75679SN/A# cache.hit_latency = 3 76679SN/A# cache.assoc = 8 77679SN/A# 78679SN/A# The magic lies in the mapping of the Python attributes for SimObject 79679SN/A# classes to the actual SimObject parameter specifications. This 80679SN/A# allows parameter validity checking in the Python code. Continuing 81679SN/A# the example above, the statements "cache.blurfl=3" or 82679SN/A# "cache.assoc='hello'" would both result in runtime errors in Python, 83679SN/A# since the BaseCache object has no 'blurfl' parameter and the 'assoc' 84679SN/A# parameter requires an integer, respectively. This magic is done 85679SN/A# primarily by overriding the special __setattr__ method that controls 86679SN/A# assignment to object attributes. 87679SN/A# 88679SN/A# Once a set of Python objects have been instantiated in a hierarchy, 89679SN/A# calling 'instantiate(obj)' (where obj is the root of the hierarchy) 902740SN/A# will generate a .ini file. 91679SN/A# 92679SN/A##################################################################### 93679SN/A 944762Snate@binkert.org# list of all SimObject classes 954762Snate@binkert.orgallClasses = {} 964762Snate@binkert.org 972738SN/A# dict to look up SimObjects based on path 982738SN/AinstanceDict = {} 992738SN/A 1007673Snate@binkert.orgdef default_cxx_predecls(cls, code): 1017673Snate@binkert.org '''A forward class declaration is sufficient since we are 1027673Snate@binkert.org just declaring a pointer.''' 1037673Snate@binkert.org 1047673Snate@binkert.org class_path = cls._value_dict['cxx_class'].split('::') 1057673Snate@binkert.org for ns in class_path[:-1]: 1067673Snate@binkert.org code('namespace $ns {') 1077673Snate@binkert.org code('class $0;', class_path[-1]) 1087673Snate@binkert.org for ns in reversed(class_path[:-1]): 1097673Snate@binkert.org code('/* namespace $ns */ }') 1107673Snate@binkert.org 1117673Snate@binkert.orgdef default_swig_objdecls(cls, code): 1127673Snate@binkert.org class_path = cls.cxx_class.split('::') 1137673Snate@binkert.org classname = class_path[-1] 1147673Snate@binkert.org namespaces = class_path[:-1] 1157673Snate@binkert.org 1167673Snate@binkert.org for ns in namespaces: 1177673Snate@binkert.org code('namespace $ns {') 1187673Snate@binkert.org 1197673Snate@binkert.org if namespaces: 1207673Snate@binkert.org code('// avoid name conflicts') 1217673Snate@binkert.org sep_string = '_COLONS_' 1227673Snate@binkert.org flat_name = sep_string.join(class_path) 1237673Snate@binkert.org code('%rename($flat_name) $classname;') 1247673Snate@binkert.org 1257673Snate@binkert.org code() 1267673Snate@binkert.org code('// stop swig from creating/wrapping default ctor/dtor') 1277673Snate@binkert.org code('%nodefault $classname;') 1287673Snate@binkert.org code('class $classname') 1297673Snate@binkert.org if cls._base: 1307673Snate@binkert.org code(' : public ${{cls._base.cxx_class}}') 1317673Snate@binkert.org code('{};') 1327673Snate@binkert.org 1337673Snate@binkert.org for ns in reversed(namespaces): 1347673Snate@binkert.org code('/* namespace $ns */ }') 1357673Snate@binkert.org 1367673Snate@binkert.orgdef public_value(key, value): 1377673Snate@binkert.org return key.startswith('_') or \ 1387673Snate@binkert.org isinstance(value, (FunctionType, MethodType, classmethod, type)) 1397673Snate@binkert.org 1402740SN/A# The metaclass for SimObject.
