Hi everyone,
I am new to gem5.
I am trying to use the following scripts to run spec2006,
"
#cmp.py
# Simple configuration script
import os, optparse, sys
import m5
from m5.defines import buildEnv
from m5.objects import *
from m5.util import addToPath
addToPath('../common')
addToPath('../ruby')
addToPath('../topologies')
import Options
import Ruby
import Simulation
from Caches import *
import CacheConfig
import cpu2006
# Get paths we might need. It's expected this file is in
m5/configs/example.
config_path = os.path.dirname(os.path.abspath(__file__))
print config_path # 'configs/cpu2006'
config_root = os.path.dirname(config_path)
print config_root
m5_root = os.path.dirname(config_root)
print m5_root
parser = optparse.OptionParser()
Options.addCommonOptions(parser)
Options.addSEOptions(parser)
# Benchmark options
parser.add_option("-b", "--benchmark", default="",
help="The benchmark to be loaded.")
parser.add_option("--chkpt", default="",
help="The checkpoint to load.")
execfile(os.path.join(config_root, "common", "Options.py"))
if '--ruby' in sys.argv:
Ruby.define_options(parser)
(options, args) = parser.parse_args()
if args:
print "Error: script doesn't take any positional arguments"
sys.exit(1)
if options.benchmark == 'perlbench':
process = cpu2006.perlbench
elif options.benchmark == 'bzip2':
process = cpu2006.bzip2
# intend to hide several codes of spec benchemarks claim
elif options.benchmark == 'specrand_f':
process = cpu2006.specrand_f
if options.chkpt != "":
process.chkpt = options.chkpt
(CPUClass, test_mem_mode, FutureClass) = Simulation.setCPUClass(options)
CPUClass.clock = '1.0GHz'
#np = options.num_cpus
np = 1
system = System(cpu = [CPUClass(cpu_id=i) for i in xrange(np)],
physmem = SimpleMemory(range=AddrRange("1024MB")),
membus = CoherentBus(), mem_mode = 'timing')
if options.ruby:
if not (options.cpu_type == "detailed" or options.cpu_type == "timing"):
print >> sys.stderr, "Ruby requires TimingSimpleCPU or O3CPU!!"
sys.exit(1)

for i in xrange(np):
ruby_port = system.ruby._cpu_ruby_ports[i]
# Create the interrupt controller and connect its ports to Ruby
# Note that the interrupt controller is always present but only
# in x86 does it have message ports that need to be connected
system.cpu[i].createInterruptController()
# Connect the cpu's cache ports to Ruby
system.cpu[i].icache_port = ruby_port.slave
system.cpu[i].dcache_port = ruby_port.slave
if buildEnv['TARGET_ISA'] == 'x86':
system.cpu[i].interrupts.pio = ruby_port.master
system.cpu[i].interrupts.int_master = ruby_port.slave
system.cpu[i].interrupts.int_slave = ruby_port.master
system.cpu[i].itb.walker.port = ruby_port.slave
system.cpu[i].dtb.walker.port = ruby_port.slave
else:
system.physmem.port = system.membus.master
system.system_port = system.membus.slave
CacheConfig.config_cache(options,system)
for i in xrange(np):
# if options.caches:

system.cpu[i].workload = process[i]
root = Root(full_system = False,system = system)
Simulation.run(options, root, system, FutureClass)
"
but i always get the following error:
" File "<string>", line 1, in <module>
File "/home/yang/gem5/src/python/m5/main.py", line 388, in main
exec filecode in scope
File "./configs/example/cmp.py", line 122, in <module>
CPUClass.clock = '1.0GHz'
File "/home/yang/gem5/src/python/m5/SimObject.py", line 349, in
__setattr__
"Class %s has no parameter \'%s\'" % (cls.__name__, attr)
AttributeError: Class AtomicSimpleCPU has no parameter 'clock'"
I am wondering how this happens. The code is almost the same to the
examples in wiki.
Thanks,
