2006-07-05Add some different parameters. The main change is that the writeback count ↵Kevin Lim
is now limited so that it doesn't overflow the buffer. 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. --HG-- extra : convert_revision : 31c8cc495273e3c481b79055562fc40f71291fc4

Also fix up serialization; the nameOut() was messing up the ordering. src/cpu/simple/timing.cc: Add in quiesce, fix up serialization. src/cpu/simple/timing.hh: Add in queisce, fix up serialization. --HG-- extra : convert_revision : 9d59d53bdf269d4d82fb119e5ae7c8a5d475880b
2006-06-29Add in support for quiescing the system, taking checkpoints, restoring from ↵Kevin Lim
checkpoints, changing memory modes, and switching CPUs. 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. --HG-- extra : convert_revision : a8c738d3911c68d5a7caf7de24d732dcc62cfb61

2006-06-16Two updates that got combined into one ChangeSet accidentally. They're both ↵Kevin Lim
pretty simple so they shouldn't cause any trouble. First: Rename FullCPU and its variants in the o3 directory to O3CPU to differentiate from the old model, and also to specify it's an out of order model. Second: Include build options for selecting the Checker to be used. These options make sure if the Checker is being used there is a CPU that supports it also being compiled. SConstruct: Add in option USE_CHECKER to allow for not compiling in checker code. The checker is enabled through this option instead of through the CPU_MODELS list. However it's still necessary to treat the Checker like a CPU model, so it is appended onto the CPU_MODELS list if enabled. configs/test/test.py: Name change for DetailedCPU to DetailedO3CPU. Also include option for max tick. src/base/traceflags.py: Add in O3CPU trace flag. src/cpu/SConscript: Rename AlphaFullCPU to AlphaO3CPU. Only include checker sources if they're necessary. Also add a list of CPUs that support the Checker, and only allow the Checker to be compiled in if one of those CPUs are also being included. src/cpu/base_dyn_inst.cc: src/cpu/base_dyn_inst.hh: Rename typedef to ImplCPU instead of FullCPU, to differentiate from the old FullCPU. src/cpu/cpu_models.py: src/cpu/o3/alpha_cpu.cc: src/cpu/o3/alpha_cpu.hh: src/cpu/o3/alpha_cpu_builder.cc: src/cpu/o3/alpha_cpu_impl.hh: Rename AlphaFullCPU to AlphaO3CPU to differentiate from old FullCPU model. src/cpu/o3/alpha_dyn_inst.hh: src/cpu/o3/alpha_dyn_inst_impl.hh: src/cpu/o3/alpha_impl.hh: src/cpu/o3/alpha_params.hh: src/cpu/o3/commit.hh: src/cpu/o3/cpu.hh: src/cpu/o3/decode.hh: src/cpu/o3/decode_impl.hh: src/cpu/o3/fetch.hh: src/cpu/o3/iew.hh: src/cpu/o3/iew_impl.hh: src/cpu/o3/inst_queue.hh: src/cpu/o3/lsq.hh: src/cpu/o3/lsq_impl.hh: src/cpu/o3/lsq_unit.hh: src/cpu/o3/regfile.hh: src/cpu/o3/rename.hh: src/cpu/o3/rename_impl.hh: src/cpu/o3/rob.hh: src/cpu/o3/rob_impl.hh: src/cpu/o3/thread_state.hh: src/python/m5/objects/AlphaO3CPU.py: Rename FullCPU to O3CPU to differentiate from old FullCPU model. src/cpu/o3/commit_impl.hh: src/cpu/o3/cpu.cc: src/cpu/o3/fetch_impl.hh: src/cpu/o3/lsq_unit_impl.hh: Rename FullCPU to O3CPU to differentiate from old FullCPU model.
