# CpuModel class
#
# The CpuModel class encapsulates everything the ISA parser needs to
# know about a particular CPU model.
class CpuModel:
# Dict of available CPU model objects. Accessible as CpuModel.dict.
dict = {}
# Constructor. Automatically adds models to CpuModel.dict.
def __init__(self, name, filename, includes, strings):
self.name = name
self.filename = filename # filename for output exec code
self.includes = includes # include files needed in exec file
# The 'strings' dict holds all the per-CPU symbols we can
# substitute into templates etc.
self.strings = strings
# Add self to dict
CpuModel.dict[name] = self
#
# Define CPU models.
#
# Parameters are:
# - name of model
# - filename for generated ISA execution file
# - includes needed for generated ISA execution file
# - substitution strings for ISA description templates

Split SimpleCPU into two different models, AtomicSimpleCPU and TimingSimpleCPU, which use atomic and timing memory accesses respectively. Common code is factored into the BaseSimpleCPU class. AtomicSimpleCPU includes an option (simulate_stalls) to add delays based on the estimated latency reported by the atomic accesses. Plain old "SimpleCPU" is gone; I have not updated all the config files (just test/test.py). Also fixes to get timing accesses working in new memory model and to get split-phase memory instruction definitions working with new memory model as well. arch/alpha/isa/main.isa: Need to include packet_impl.h for functions that use Packet objects. arch/alpha/isa/mem.isa: Change completeAcc() methods to take Packet object pointers. Also split out StoreCond template for completeAcc(), since that's the only one that needs write_result and we get an unused variable warning if we always have it in there. build/SConstruct: Update list of recognized CPU model names. configs/test/test.py: Change SimpleCPU to AtomicSimpleCPU. cpu/SConscript: Define sources for new CPU models. Add split memory access methods to CPU model signatures. cpu/cpu_models.py: cpu/static_inst.hh: Define new CPU models. cpu/simple/base.cc: cpu/simple/base.hh: Factor out pieces specific to Atomic or Timing models. mem/bus.cc: Bus needs to be able to route timing packets based on explicit dest so responses can get back to requester. Set dest to Packet::Broadcast to indicate that dest should be derived from address. Also set packet src field based on port from which packet is sent. mem/bus.hh: Set packet src field based on port from which packet is sent. mem/packet.hh: Define Broadcast destination address to indicate that packet should be routed based on address. mem/physical.cc: Set packet dest on response so packet is routed back to requester properly. mem/port.cc: Flag blob packets as Broadcast. python/m5/objects/PhysicalMemory.py: Change default latency to be 1 cycle. --HG-- rename : cpu/simple/cpu.cc => cpu/simple/base.cc rename : cpu/simple/cpu.hh => cpu/simple/base.hh extra : convert_revision : e9646af6406a20c8c605087936dc4683375c2132

Two updates that got combined into one ChangeSet accidentally. They're both 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.
