src/cpu/o3/alpha_cpu_builder.cc:
src/cpu/o3/alpha_params.hh:
Add in dispatchWidth, wbWidth, wbDepth parameters. wbDepth is the number of cycles of wbWidth instructions that can be buffered.
src/cpu/o3/iew.hh:
Include separate parameter for dispatch width.
Also limit the number of outstanding writebacks so the writeback buffer isn't overflowed. The IQ must make sure with the IEW stage that it can issue instructions prior to issuing.
src/cpu/o3/iew_impl.hh:
Include separate parameter for dispatch width.
Also limit the number of outstanding writebacks so the writeback buffer isn't overflowed.
src/cpu/o3/inst_queue_impl.hh:
IQ needs to check with the IEW to make sure it can issue instructions, and increments the IEW wb counter each time there is an outstanding instruction that will writeback.
src/cpu/o3/lsq_unit_impl.hh:
Be sure to decrement the writeback counter if there's a squashed load that returned.
src/python/m5/objects/AlphaO3CPU.py:
Change the parameters to include dispatch width, writeback width, and writeback depth.

Key new functions that can be called on the m5 object at the python interpreter:
doQuiesce(root) - A helper function that quiesces the object passed in and all of its children.
resume(root) - Another helper function that tells the object and all of its children that the quiesce is over.
checkpoint(root) - Takes a checkpoint of the system. Checkpoint directory must be set before hand.
setCheckpointDir(name) - Sets the checkpoint directory.
restoreCheckpoint(root) - Restores the values from the checkpoint located in the checkpoint directory.
changeToAtomic(system) - Changes the system and all of its children to atomic memory mode.
changeToTiming(system) - Changes the system and all of its children to timing memory mode.
switchCpus(list) - Takes in a list of tuples, where each tuple is a pair of (old CPU, new CPU). Quiesces the old CPUs, and then switches over to the new CPUs.
src/SConscript:
Remove serializer, replaced by python code.
src/python/m5/__init__.py:
Updates to support quiescing, checkpointing, changing memory modes, and switching CPUs.
src/python/m5/config.py:
Several functions defined on the SimObject for quiescing, changing timing modes, and switching CPUs
src/sim/main.cc:
Add some extra functions that are exported to python through SWIG.
src/sim/serialize.cc:
Change serialization around a bit. Now it is controlled through Python, so there's no need for SerializeEvents or SerializeParams.
Also add in a new unserializeAll() function that loads a checkpoint and handles unserializing all objects.
src/sim/serialize.hh:
Add unserializeAll function and a setCheckpointName function.
src/sim/sim_events.cc:
Add process() function for CountedQuiesceEvent, which calls exitSimLoop() once its counter reaches 0.
src/sim/sim_events.hh:
Add in a CountedQuiesceEvent, which is used when the system is preparing to quiesce. Any objects that can't be quiesced immediately are given a pointer to a CountedQuiesceEvent. The event has its counter set via Python, and as objects finish quiescing they call process() on the event. Eventually the event causes the simulation to stop once all objects have quiesced.
src/sim/sim_object.cc:
Add a few functions for quiescing, checkpointing, and changing memory modes.
src/sim/sim_object.hh:
Add a state variable to all SimObjects that tracks both the timing mode of the object and the quiesce state of the object. Currently this isn't serialized, and I'm not sure it needs to be so long as the timing mode starts up the same after a checkpoint.

The changes largely are fixing up the memory accesses to use ports/Requests/Packets, supporting the splitting off of instantiation of template classes, and handling some of the reorganization that happened.
