error in simulating sample.py on gem5: "AttributeError: Not allowed to set pio on 'SimObjectVector' "

I have been trying to simulate the 'simple.py' code on gem5 from the gem5 tutorial. Link of the tutorial is: http://pages.cs.wisc.edu/~david/courses/cs752/Spring2015/gem5-tutorial/part1/simple_config.html#simple-config-fig

I am getting an error saying that "AttributeError: Not allowed to set pio on 'SimObjectVector'".

Does anyone know how to resolve it?

for this you are getting the error due to the confusion in the ISA architecture and the binary architecture..

isa = str(m5.defines.buildEnv['KVM_ISA']).lower()
if isa == "x86" and  m5.defines.buildEnv['USE_ARM_ISA']==False:
    system.cpu.interrupts[0].pio = system.membus.mem_side_ports
    system.cpu.interrupts[0].int_requestor = system.membus.cpu_side_ports
    system.cpu.interrupts[0].int_responder = system.membus.mem_side_ports

if your ISA is not an x86 you cant use the pio interrupt #gem5
