2006-07-07Switch out fixes for CPUs.Kevin Lim
src/cpu/o3/cpu.cc: Fix up keeping proper state when switched out and drained. src/cpu/simple/timing.cc: src/cpu/simple/timing.hh: Keep track of the event we use to schedule fetch initially and upon resume. We may have to cancel the event if the CPU is switched out. --HG-- extra : convert_revision : 60a2a1bd2cdc67bd53ca4a67aa77166c826a4c8c

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.

2006-06-09Move main control from C++ into Python.Steve Reinhardt
User script now invokes initialization and simulation loop after building configuration. These functions are exported from C++ to Python using SWIG. SConstruct: Set up SWIG builder & scanner. Set up symlinking of source files into build directory (by not disabling the default behavior). configs/test/test.py: Rewrite to use new script-driven interface. Include a sample option. src/SConscript: Set up symlinking of source files into build directory (by not disabling the default behavior). Add SWIG-generated main_wrap.cc to source list. src/arch/SConscript: Set up symlinking of source files into build directory (by not disabling the default behavior). src/arch/alpha/ev5.cc: src/arch/alpha/isa/decoder.isa: src/cpu/o3/alpha_cpu_impl.hh: src/cpu/trace/opt_cpu.cc: src/cpu/trace/trace_cpu.cc: src/sim/pseudo_inst.cc: src/sim/root.cc: src/sim/serialize.cc: src/sim/syscall_emul.cc: SimExit() is now exitSimLoop(). src/cpu/base.cc: SimExitEvent is now SimLoopExitEvent src/python/SConscript: Add SWIG build command for main.i. Use python/m5 in build dir as source for zip archive... easy now with file duplication enabled. src/python/m5/__init__.py: - Move copyright notice back to C++ so we can print it right away, even for interactive sessions. - Get rid of argument parsing code; just provide default option descriptors for user script to call optparse with. - Don't clutter m5 namespace by sucking in all of m5.config and m5.objects. - Move instantiate() function here from config.py. src/python/m5/config.py: - Move instantiate() function to __init__.py. - Param.Foo deferred type lookups must use m5.objects namespace now (not m5). src/python/m5/objects/AlphaConsole.py: src/python/m5/objects/AlphaFullCPU.py: src/python/m5/objects/AlphaTLB.py: src/python/m5/objects/BadDevice.py: src/python/m5/objects/BaseCPU.py: src/python/m5/objects/BaseCache.py: src/python/m5/objects/Bridge.py: src/python/m5/objects/Bus.py: src/python/m5/objects/CoherenceProtocol.py: src/python/m5/objects/Device.py: src/python/m5/objects/DiskImage.py: src/python/m5/objects/Ethernet.py: src/python/m5/objects/Ide.py: src/python/m5/objects/IntrControl.py: src/python/m5/objects/MemObject.py: src/python/m5/objects/MemTest.py: src/python/m5/objects/Pci.py: src/python/m5/objects/PhysicalMemory.py: src/python/m5/objects/Platform.py: src/python/m5/objects/Process.py: src/python/m5/objects/Repl.py: src/python/m5/objects/Root.py: src/python/m5/objects/SimConsole.py: src/python/m5/objects/SimpleDisk.py: src/python/m5/objects/System.py: src/python/m5/objects/Tsunami.py: src/python/m5/objects/Uart.py: Fix up imports (m5 namespace no longer includes m5.config). src/sim/eventq.cc: src/sim/eventq.hh: Support for Python-called simulate() function: - Use IsExitEvent flag to signal events that want to exit the simulation loop gracefully (instead of calling exit() to terminate the process). - Modify interface to hand exit event object back to caller so it can be inspected for cause. src/sim/host.hh: Add MaxTick constant. src/sim/main.cc: Move copyright notice back to C++ so we can print it right away, even for interactive sessions. Use PYTHONPATH environment var to set module path (instead of clunky code injection method). Move main control from here into Python: - Separate initialization code and simulation loop into separate functions callable from Python. - Make Python interpreter invocation more pure (more like directly invoking interpreter). Add -i and -p flags (only options on binary itself; other options processed by Python). Import readline package when using interactive mode. src/sim/sim_events.cc: SimExitEvent is now SimLoopExitEvent, and uses IsSimExit flag to terminate loop (instead of exiting simulator process). src/sim/sim_events.hh: SimExitEvent is now SimLoopExitEvent, and uses IsSimExit flag to terminate loop (instead of exiting simulator process). Get rid of a few unused constructors. src/sim/sim_exit.hh: SimExit() is now exitSimLoop(). Get rid of unused functions.

2006-06-09Fixes for some outstanding issues in the LSQ. It should now be able to ↵Kevin Lim
retry. It should also be able to handle LL/SC (through hacks) for the UP case. src/cpu/o3/lsq_unit.hh: Handle being able to retry (untested but hopefully very close to working). Handle lock flag for LL/SC hack. Hopefully the memory system will add in LL/SC soon. Better output message. src/cpu/o3/lsq_unit_impl.hh: Handle being able to retry (untested but should be very close to working).
