My cmp.py script looks like:
...
(CPUClass, test_mem_mode, FutureClass) = Simulation.setCPUClass(options)
CPUClass.clock = '1.0GHz'
np = options.num_cpus
...
cpus = [CPUClass(cpu_id=i) for i in xrange(np)]
# ----------------------
# Create a system, and add system wide objects
# ----------------------
system = System(cpu = cpus, physmem = PhysicalMemory(range=AddrRange("512MB")),
membus = Bus(clock = '1.0GHz'))
system.toL2bus = Bus(clock = '1.0GHz')
system.l2 = L2Cache()
# ----------------------
# Connect the L2 cache and memory together
# ----------------------
system.physmem.port = system.membus.master
system.l2.cpu_side = system.toL2bus.master
system.l2.mem_side = system.membus.slave
system.system_port = system.membus.slave
# ----------------------
# Connect the L2 cache and clusters together
# ----------------------
for cpu in cpus:
cpu.addPrivateSplitL1Caches(L1Cache(),
L1Cache())
# connect cpu level-1 caches to shared level-2 cache
cpu.connectAllPorts(system.toL2bus, system.membus)
...
root = Root(full_system = False, system = system)
Simulation.run(options, root, system, FutureClass)
and the command line and the error I get is:
command line: build/X86/m5.debug configs/example/cmp.py -F 1000000
--maxtick 1000000000 --cpu-type detailed --caches --l2cache -b
bzip2_dryer

@ cycle 0

Please note that the error happens right after beginning of the
simulation (which should be in AtomicSimpleCPU).
Thanks for any feedback
