switch_cpu_list = [(cpu,cpu2)]
m5.simulate(3663496423522)
m5.switchCpus(switch_cpu_list)
exit_event = m5.simulate(maxtick)
Most other options I've left the same from the fs.py script, but when I run the simulator, it works perfectly until the switch point and then dies with:
Switching CPUs
Traceback (most recent call last):
File "<string>", line 1, in ?
File "build/ALPHA_FS/python/m5/main.py", line 314, in main
execfile(sys.argv[0], scope)
File "configs/example/fsSwap.py", line 86, in ?
m5.switchCpus(switch_cpu_list)
File "build/ALPHA_FS/python/m5/__init__.py", line 206, in switchCpus
new_cpu.takeOverFrom(old_cpus[index])
File "build/ALPHA_FS/python/m5/config.py", line 570, in takeOverFrom
self._ccObject.takeOverFrom(cpu_ptr)
AttributeError: 'NoneType' object has no attribute 'takeOverFrom'
Is there something I'm forgetting to instantiate? Any help would be greatly appreciate.
Ps. Thanks for setting up the WIKI page. It has been a tremendous help, and in my opinion a great improvement over the documentation that was available for the previous version of m5. I hope the community continues to add to it!
