Inital split up of the header files for the new memory system. Still need to fill in some of the include files, and other data types. But this will be the starting point. mem/bus.hh: Inital crack at a bus object that has ports. Still need to clean up the include file issues. mem/mem_object.hh: Decleration of a base memory object. Derives from simobject and adds a function to get the port associated with the object. mem/packet.hh: Inital crack at the packet decleration. Still need to clean up the include file issues. mem/port.hh: Inital crack at the port decleration. Still need to clean up the include file issues. mem/request.hh: Inital crack at the request decleration.

Many changes that make the new mem system compile. Now to convert the rest of the tree to use the new mem system. mem/mem_object.hh: Create constrtor so it compiles mem/packet.hh: Fix typedefs so they compile, add in a few more headers for compilation mem/page_table.cc: convert to new mem system so it compiles mem/page_table.hh: fix it to the version that had asid support. Make it compile in the new system mem/physical.cc: Fix some compilation bugs mem/physical.hh: Add a type that made compile fail mem/port.hh: Fix a spelling error that messed up compilation mem/request.hh: fix typedefs and forward declerations so it compiles --HG-- extra : convert_revision : 580fb1ba31ada799ff0122601b8b5a8d994bb8af

/** Additional function to return the Port of a memory object. */
Move SimObject creation and Port connection loops into Python. Add Port and VectorPort objects and support for specifying port connections via assignment.

Add support for declaring and connecting MemObject ports in Python. src/python/m5/objects/Bus.py: src/python/m5/objects/PhysicalMemory.py: Add port declaration. src/sim/builder.cc: src/sim/builder.hh: src/sim/serialize.cc: src/sim/serialize.hh: ConfigNodes are gone; builder just gets the name of a .ini file section now. src/sim/main.cc: Move SimObject construction and port connection operations into Python (with C++ calls). Split remaining initialization operations into two parts, loadIniFile() and finalInit(). src/sim/param.cc: src/sim/param.hh: SimObject resolution done globally in Python now (not via ConfigNode hierarchy). src/sim/sim_object.cc: Remove unneeded #include. --HG-- extra : convert_revision : 2fa4001eaaec0c9a4231ef6e854f8e156d930dfe
