2006-06-22Changes to get OzoneCPU to compile once more.Kevin Lim
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. OzoneCPU is untested for now but at least compiles. Fixes will be coming shortly. SConstruct: Remove OzoneSimpleCPU from list of CPUs. src/cpu/SConscript: Leave out OzoneSimpleCPU. src/cpu/ozone/bpred_unit.cc: Fixes to get OzoneCPU to compile. src/cpu/ozone/checker_builder.cc: src/cpu/ozone/cpu.cc: src/cpu/ozone/cpu.hh: src/cpu/ozone/cpu_builder.cc: src/cpu/ozone/cpu_impl.hh: src/cpu/ozone/dyn_inst.hh: src/cpu/ozone/dyn_inst_impl.hh: src/cpu/ozone/front_end.cc: src/cpu/ozone/front_end.hh: src/cpu/ozone/front_end_impl.hh: src/cpu/ozone/lw_back_end.hh: src/cpu/ozone/lw_back_end_impl.hh: src/cpu/ozone/lw_lsq.hh: src/cpu/ozone/lw_lsq_impl.hh: src/cpu/ozone/ozone_impl.hh: src/cpu/ozone/rename_table.cc: src/cpu/ozone/simple_params.hh: src/cpu/ozone/thread_state.hh: Fixes to get OzoneCPU back to compiling. --HG-- extra : convert_revision : 90ffb397263bcf9fea3987317272c64f2b20f7e6

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.

2006-06-15Get Port stuff working with full-system scripts.Steve Reinhardt
Key was adding support for cloning port references (trickier than it sounds). Got rid of class/instance thing and go back to instance cloning... still don't allow changing SimObject parameters/children after a class (instance) has been subclassed or instantiated (or cloned), which should avoid bizarre unintended behavior. configs/test/fs.py: Add ".port" to busses to get a port reference. Get rid of commented-out code. src/python/m5/__init__.py: resolveSimObject should call getCCObject() instead of createCCObject() to avoid cycles in recursively creating objects. src/python/m5/config.py: Get rid of class/instance thing and go back to instance cloning. Deep copy has to happen only on instance cloning then (and not on subclassing). Add getCCObject() method to force creation of C++ SimObject without recursively creating its children. Add support for cloning port references (trickier than it sounds). Also clean up some very obsolete comments. src/python/m5/objects/Bridge.py: src/python/m5/objects/Device.py: Add ports. --HG-- extra : convert_revision : 4816d05ead0de520748aace06dbd1911a33f0af8
