+# M5 Python Configuration Utility
+#
+# The basic idea is to write simple Python programs that build Python
+# objects corresponding to M5 SimObjects for the deisred 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('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.
