9f18764441 Commiting a version of the multi-phase snoop atomic bus so people can see the framework. Doesn't work, but also doesn't break uni-processor systems.
Working on pulling out the changes in the cache so that it remains working.

    Changes for multi-phase snoop
    Some code for registering snoop ranges (a version that compiles and runs, but does nothing)

2f145ac54a Fix Physical Memory to allow memory sizes bigger than 128MB.
Kinda port DRAM to new memory system. The code is *really* ugly (not my fault) and right now something about the stats it uses
causes a simulator segfault.

    Add dram.cc to sconscript
src/mem/physical.cc:

    Add params struct to physical memory, use params, make latency function be virtual

19ca97af79 This changeset gets the MIPS ISA pretty much working in the O3CPU. It builds, runs, and gets very very close to completing the hello world
succesfully but there are some minor quirks to iron out. Who would've known a DELAY SLOT introduces that much complexity?! arrgh!

Anyways, a lot of this stuff had to do with my project at MIPS and me needing to know how I was going to get this working for the MIPS
ISA. So I figured I would try to touch it up and throw it in here (I hate to introduce non-completely working components... )

4bd025742d Put regression tests back into m5. They are located in the "tests" directory. The directory output and reference outputs have changed slightly. Now the directory is ALPHA_SE/test/<test>/<cpu_model>/, and for the reference stats <test>/ref/<arch>/<cpu_model>
Right now only non-SMT SE regression tests have been added back in.  The rest are pending getting SMT working, and consolidating the FS configuration files.

Eventually support for different OSs can be added so you can specify which versions of the binary you want to run from one config file.

Note: mp-test1 doesn't have any reference stats because MP mode doesn't currently work.  The test itself should probably work once the code is fixed.

SConstruct:
    Updates to allow for regression tests to work via the command line "scons build/ALPHA_SE/test/debug/quick" and such once again.
src/cpu/SConscript:
    Keep a list of SMT supporting CPUs so that the regression tests can easily specify which CPUs to use if they are SMT only.

src/cpu/o3/lsq.hh:

1ccfdb442f Timing cache works for hello world test.
Still need
1) detailed CPU (blocking ability in cache)
1a) Multiple outstanding requests (need to keep track of times for events)
2)Multi-level support
3)MP coherece support
4)LL/SC support
5)Functional path needs to be correctly implemented (temporarily works without multiple outstanding requests (simple cpu))

src/cpu/simple/timing.cc:
    Temp hack because timing cpu doesn't export ports properly so single I/D cache communicates only through the Icache port.
src/mem/cache/base_cache.cc:
    Handle marking MSHR's in service
    Add support for getting CSHR's
src/mem/cache/base_cache.hh:
    Make these functions visible at the base cache level
src/mem/cache/cache.hh:

src/mem/cache/cache_impl.hh:

src/mem/packet.hh:

8ae4f45bc4 Fixes for draining.
src/cpu/simple/timing.cc:
    Update for changed return values.
src/python/m5/__init__.py:
    Loop in order to make sure all objects are really drained.  Objects may become undrained as other objects become drained (e.g. a bus-bridge has a packet, while a bus is empty, and the first drain() will cause the bus-bridge to give the packet to the bus).

    The only case we know every object is actually drained is if they all return immediately that they are drained.

7a49298134 AtomicSimpleCPU with a cache now runs the hello world! test program.
Need to clean up a bunch of flags/hacks in the code.  Then onto Timming mode.

Functional accesses also work properly, although not exactly how we wanted them.  I'll need to clean that up as well.

src/cpu/simple/atomic.cc:
    Atomic CPU needs to set thread context so stats work in cache.  Temporarily just use CPU=0 ThreadID=0
src/mem/cache/cache_impl.hh:
    Need to return success/failure properly still
    Physical memory object doesn't assert SATISFIED anymore, need to remove that flag
src/mem/cache/tags/lru.cc:
    Doesn't work if the REQ doesn't set it's ASID.  Temporary fix use 0 always

f64c175f9a Add in support for quiescing the system, taking checkpoints, restoring from 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.

393e77fbe9 Change options back to just being flags instead of taking in a True/False value.
src/python/m5/__init__.py:
    Change up options.  Now setting the flag enables/disables, each of which is the opposite of the default values found in the Python class.

dfe0ea6cba Fix up code to be able to use the Checker.
SConstruct:
    Remove check for Checker from this SConstruct
src/arch/SConscript:
    Specific check if CheckerCPU is being used.  Not the cleanest, but works for now.
src/cpu/SConscript:
    Code to handle using the CheckerCPU a little better.  Allows -c to be used normally.

f3d74759ca Split off instantiation into separate CC files for each of the models. This makes it easier to be able to specify only certain CPU models.
src/cpu/SConscript:
    Split off instantiations into separate CC files.  This makes it easier to split them per CPU model.
src/cpu/base_dyn_inst_impl.hh:
    Move instantations out of impl.hh file and into a cc file.
src/cpu/checker/cpu_impl.hh:
    Move instantiations over to .cc files inside each CPU's directory.  Makes it easier to only use what's actually included.
src/cpu/o3/bpred_unit.cc:
    Pull Ozone instantiations out of this .cc file; put them into the ozone's CC file.
src/cpu/o3/checker_builder.cc:
    Instantiate Checker for O3 CPU.
