Enable building only selected CPU models via new scons CPU_MODELS parameter. For example: scons CPU_MODELS="SimpleCPU,FullCPU" ALPHA_SE/m5.debug Unfortunately the option is not sticky due to a scons bug with saving & restoring ListOption parameters. SConscript: Separate out cpu-model-specific files so they can be conditionally included based on value of new CPU_MODELS parameter. Most of these are now handled in cpu/SConscript, except for FullCPU which is still in this file. arch/SConscript: The set of CPU-model-specific execute files must now be determined from the CPU_MODELS parameter, via the new cpu_models.py file. Also pass the list of configured CPU models to isa_parser.py. arch/isa_parser.py: Move CpuModel definition and objects out to a separate file so they can be shared with scons. Global list of CPU models to generate code for is now controlled by command-line parameters (so we can do only a subset of the available ones). build/SConstruct: Define new CPU_MODELS ListOption. cpu/static_inst.hh: Rename static_inst_impl.hh to static_inst_exec_sigs.hh. --HG-- extra : convert_revision : 163df32a76d4c05900490b2bce4c7962a5e3f614

# 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

Add in checker. Supports dynamically verifying the execution of instructions, as well as limited amount of control path verification. It will verify anything within the program, but anything external (traps, interrupts, XC) it assumes is redirected properly by the CPU. Similarly it assumes the results of store conditionals, uncached loads, and instructions marked as "unverifiable" are correct from the CPU. base/traceflags.py: build/SConstruct: cpu/SConscript: cpu/cpu_models.py: Add in Checker. cpu/base.cc: Add in checker support.
