From cf05fa476df711f64d0481117cf075ce68676d57 Mon Sep 17 00:00:00 2001 From: Nathan Binkert Date: Fri, 11 Mar 2005 18:28:38 -0500 Subject: stick all python stuff into a top level python directory. create an m5 package in python/m5 move the objects package into the m5 package move the m5config into the m5 package as config leave both importers outside of the package. SConscript: sim/main.cc: move sim/pyconfig/* -> python python/SConscript: m5config.py -> m5/config.py (now automatically embedded) objects -> python/m5/objects embed all python files in python/m5 python/m5/config.py: importer renamed mpy_importer move code to m5/__init__.py test/genini.py: deal with new python organization keep track of paths we want to add and add them after parameters are parsed. --HG-- rename : sim/pyconfig/SConscript => python/SConscript rename : sim/pyconfig/m5config.py => python/m5/config.py rename : objects/AlphaConsole.mpy => python/m5/objects/AlphaConsole.mpy rename : objects/AlphaTLB.mpy => python/m5/objects/AlphaTLB.mpy rename : objects/BadDevice.mpy => python/m5/objects/BadDevice.mpy rename : objects/BaseCPU.mpy => python/m5/objects/BaseCPU.mpy rename : objects/BaseCache.mpy => python/m5/objects/BaseCache.mpy rename : objects/BaseSystem.mpy => python/m5/objects/BaseSystem.mpy rename : objects/Bus.mpy => python/m5/objects/Bus.mpy rename : objects/CoherenceProtocol.mpy => python/m5/objects/CoherenceProtocol.mpy rename : objects/Device.mpy => python/m5/objects/Device.mpy rename : objects/DiskImage.mpy => python/m5/objects/DiskImage.mpy rename : objects/Ethernet.mpy => python/m5/objects/Ethernet.mpy rename : objects/Ide.mpy => python/m5/objects/Ide.mpy rename : objects/IntrControl.mpy => python/m5/objects/IntrControl.mpy rename : objects/MemTest.mpy => python/m5/objects/MemTest.mpy rename : objects/Pci.mpy => python/m5/objects/Pci.mpy rename : objects/PhysicalMemory.mpy => python/m5/objects/PhysicalMemory.mpy rename : objects/Platform.mpy => python/m5/objects/Platform.mpy rename : objects/Process.mpy => python/m5/objects/Process.mpy rename : objects/Repl.mpy => python/m5/objects/Repl.mpy rename : objects/Root.mpy => python/m5/objects/Root.mpy rename : objects/SimConsole.mpy => python/m5/objects/SimConsole.mpy rename : objects/SimpleDisk.mpy => python/m5/objects/SimpleDisk.mpy rename : objects/Tsunami.mpy => python/m5/objects/Tsunami.mpy rename : objects/Uart.mpy => python/m5/objects/Uart.mpy extra : convert_revision : aebf6ccda33028b1125974ca8b6aeab6f7570f30 --- SConscript | 7 +- objects/AlphaConsole.mpy | 9 -

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('my_cache', root, size=64*K) +# cache.hit_latency = 3 +# cache.assoc = 8 +# +# (The first two constructor arguments specify the name of the created +# cache and its parent node in the hierarchy.) +# +# 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. +# +# The Python module provides another class, ConfigNode, which is a +# superclass of SimObject. ConfigNode implements the parent/child +# relationship for building the configuration hierarchy tree. +# Concrete instances of ConfigNode can be used to group objects in the +# hierarchy, but do not correspond to SimObjects themselves (like a +# .ini section with "children=" but no "type=". +# +# 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. See simple-4cpu.py for an example +# (corresponding to m5-test/simple-4cpu.ini). +# +##################################################################### + +##################################################################### +# +# ConfigNode/SimObject classes +# +# The Python class hierarchy rooted by ConfigNode (which is the base +# class of SimObject, which in turn is the base class of all other M5 +# SimObject classes) has special attribute behavior. In general, an +# object in this hierarchy has three categories of attribute-like +# things: +# +# 1. Regular Python methods and variables. These must start with an +# underscore to be treated normally. +# +# 2. SimObject parameters. These values are stored as normal Python +# attributes, but all assignments to these attributes are checked +# against the pre-defined set of parameters stored in the class's +# _params dictionary. Assignments to attributes that do not +# correspond to predefined parameters, or that are not of the correct +# type, incur runtime errors. +# +# 3. Hierarchy children. The child nodes of a ConfigNode are stored +# in the node's _children dictionary, but can be accessed using the +# Python attribute dot-notation (just as they are printed out by the +# simulator). Children cannot be created using attribute assigment; +# they must be added by specifying the parent node in the child's +# constructor or using the '+=' operator. + +# The SimObject parameters are the most complex, for a few reasons. +# First, both parameter descriptions and parameter values are +# inherited. Thus parameter description lookup must go up the +# inheritance chain like normal attribute lookup, but this behavior +# must be explicitly coded since the lookup occurs in each class's +# _params attribute. Second, because parameter values can be set +# on SimObject classes (to implement default values), the parameter +# checking behavior must be enforced on class attribute assignments as +# well as instance attribute assignments. Finally, because we allow +# class specialization via inheritance (e.g., see the L1Cache class in +# the simple-4cpu.py example), we must do parameter checking even on +# class instantiation. To provide all these features, we use a +# metaclass to define most of the SimObject parameter behavior for +# this class hierarchy. +# +##################################################################### + +class Proxy(object): + def __init__(self, path = ()): + self._object = None + self._path = path + + def __getattr__(self, attr): + return Proxy(self._path + (attr, )) + + def __setattr__(self, attr, value): + if not attr.startswith('_'): + raise AttributeError, 'cannot set attribute %s' % attr + super(Proxy, self).__setattr__(attr, value) + + def _convert(self): + obj = self._object + for attr in self._path: + obj = obj.__getattribute__(attr) + return obj + +Super = Proxy() + +def isSubClass(value, cls): + try: + return issubclass(value, cls) + except: + return False + +def isConfigNode(value): + try: + return issubclass(value, ConfigNode) + except: + return False + +def isSimObject(value): + try: + return issubclass(value, SimObject) + except: + return False + +def isSimObjSequence(value): + if not issequence(value): + return False + + for val in value: + if not isNullPointer(val) and not isConfigNode(val): + return False + + return True + +def isParamContext(value): + try: + return issubclass(value, ParamContext) + except: + return False + + +class_decorator = 'M5M5_SIMOBJECT_' +expr_decorator = 'M5M5_EXPRESSION_' +dot_decorator = '_M5M5_DOT_' + +# The metaclass for ConfigNode (and thus for everything that derives +# from ConfigNode, including SimObject).

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('my_cache', root, size=64*K) -# cache.hit_latency = 3 -# cache.assoc = 8 -# -# (The first two constructor arguments specify the name of the created -# cache and its parent node in the hierarchy.) -# -# 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. -# -# The Python module provides another class, ConfigNode, which is a -# superclass of SimObject. ConfigNode implements the parent/child -# relationship for building the configuration hierarchy tree. -# Concrete instances of ConfigNode can be used to group objects in the -# hierarchy, but do not correspond to SimObjects themselves (like a -# .ini section with "children=" but no "type=". -# -# 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. See simple-4cpu.py for an example -# (corresponding to m5-test/simple-4cpu.ini). -# -##################################################################### - -##################################################################### -# -# ConfigNode/SimObject classes -# -# The Python class hierarchy rooted by ConfigNode (which is the base -# class of SimObject, which in turn is the base class of all other M5 -# SimObject classes) has special attribute behavior. In general, an -# object in this hierarchy has three categories of attribute-like -# things: -# -# 1. Regular Python methods and variables. These must start with an -# underscore to be treated normally. -# -# 2. SimObject parameters. These values are stored as normal Python -# attributes, but all assignments to these attributes are checked -# against the pre-defined set of parameters stored in the class's -# _params dictionary. Assignments to attributes that do not -# correspond to predefined parameters, or that are not of the correct -# type, incur runtime errors. -# -# 3. Hierarchy children. The child nodes of a ConfigNode are stored -# in the node's _children dictionary, but can be accessed using the -# Python attribute dot-notation (just as they are printed out by the -# simulator). Children cannot be created using attribute assigment; -# they must be added by specifying the parent node in the child's -# constructor or using the '+=' operator. - -# The SimObject parameters are the most complex, for a few reasons. -# First, both parameter descriptions and parameter values are -# inherited. Thus parameter description lookup must go up the -# inheritance chain like normal attribute lookup, but this behavior -# must be explicitly coded since the lookup occurs in each class's -# _params attribute. Second, because parameter values can be set -# on SimObject classes (to implement default values), the parameter -# checking behavior must be enforced on class attribute assignments as -# well as instance attribute assignments. Finally, because we allow -# class specialization via inheritance (e.g., see the L1Cache class in -# the simple-4cpu.py example), we must do parameter checking even on -# class instantiation. To provide all these features, we use a -# metaclass to define most of the SimObject parameter behavior for -# this class hierarchy. -# -##################################################################### - -class Proxy(object): - def __init__(self, path = ()): - self._object = None - self._path = path - - def __getattr__(self, attr): - return Proxy(self._path + (attr, )) - - def __setattr__(self, attr, value): - if not attr.startswith('_'): - raise AttributeError, 'cannot set attribute %s' % attr - super(Proxy, self).__setattr__(attr, value) - - def _convert(self): - obj = self._object - for attr in self._path: - obj = obj.__getattribute__(attr) - return obj - -Super = Proxy() - -def isSubClass(value, cls): - try: - return issubclass(value, cls) - except: - return False - -def isConfigNode(value): - try: - return issubclass(value, ConfigNode) - except: - return False - -def isSimObject(value): - try: - return issubclass(value, SimObject) - except: - return False - -def isSimObjSequence(value): - if not issequence(value): - return False - - for val in value: - if not isNullPointer(val) and not isConfigNode(val): - return False - - return True - -def isParamContext(value): - try: - return issubclass(value, ParamContext) - except: - return False - - -class_decorator = 'M5M5_SIMOBJECT_' -expr_decorator = 'M5M5_EXPRESSION_' -dot_decorator = '_M5M5_DOT_' - -# The metaclass for ConfigNode (and thus for everything that derives -# from ConfigNode, including SimObject).
