Re: [m5-users] Error at an ALPHA_FS configuration at v2.0b3

Thanks Ali. I got it working.

This seems a lot like a ALPHA_SE configuration file, but not like an ALPHA_FS one. You should bas your configuration file off configs/examples/fs.py. In particular it doesn't appear that you ever call makeAlphaLinuxSystem() to generate all the bits of the system that are required for full system simulation (chipsets, i/o controllers, etc). The complaint you're seeing is an attempt to find an object that inherits from Platform (e.g. Tsunami) but the simulator not finding one so it's unable to make a required connection in the system.

Hi all,

I am trying to configure a simple 1-CPU FS system for some experiments but I am getting an error and I cannot figure out a solution. My configuration script which is a combination of o3-timing.py and run.py is as follows:

---------------

import  optparse, os, sys

import m5
from m5.objects import *
m5.AddToPath('../common')
from FSConfig import *
from SysPaths import *
import Simulation

class L1Cache(BaseCache):
  assoc = 2
  block_size = 64
  latency = '1ns'
  mshrs = 10
  tgts_per_mshr = 5
  protocol = CoherenceProtocol(protocol='moesi')

class L2Cache(BaseCache):
  assoc = 8
  block_size = 64
  latency = '10ns'
  mshrs = 20
  tgts_per_mshr = 12

if not m5.build_env['FULL_SYSTEM']:
  m5.panic("This script requires full-system mode (ALPHA_FS).")

cpu = DerivO3CPU(cpu_id=0)

cpu.addTwoLevelCacheHierarchy(L1Cache(size = '128kB'), L1Cache(size = '128kB'),

                            L2Cache(size = '2MB'))
cpu.clock = '2GHz'

system = System(cpu = cpu,
              physmem = PhysicalMemory(),
              membus = Bus())
system.physmem.port = system.membus.port
cpu.connectMemPorts(system.membus)

root = Root(system = system)

# set default maxtick... script can override
# -1 means run forever
maxtick = -1

# instantiate configuration
m5.instantiate(root)

# simulate until program terminates
exit_event = m5.simulate(maxtick)

print 'Exiting @ tick', m5.curTick(), 'because', exit_event.getCause()

The error message I am getting is:

Any help would be welcome since I can't figure out what I am doing wrong.
