2007-03-23Updates for commit.Kevin Lim
1. Move interrupt handling to a separate function to clean up main commit() function a bit. Also gate the function call off properly based on whether or not there are outstanding interrupts, and the system is not in PAL mode. 2. Better handling of updating instruction's status bits. Instructions are not marked "atCommit" until other stages view it (pushed off to IEW/IQ), and they have been properly handled (faults). 3. Don't consider the ROB "empty" for the purpose of other stages until the ROB is empty, all stores have written back, and there was no store commits this cycle. The last is necessary in case a store committed, in which case it would look like all stores have written back but in actuality have not. src/cpu/o3/commit.hh: Slightly modify how interrupts are handled. Also include some extra bools to keep track of state properly. src/cpu/o3/commit_impl.hh: Slightly modify how interrupts are handled. Also include some extra bools to keep track of state. General correctness updates, most specifically for when commit broadcasts to other stages that the ROB is empty. --HG-- extra : convert_revision : 682ec6ccf4ee6ed0c8a030ceaba1c90a3619d102

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.
