Hi, Ciro and All
There is some description about switchcpu operation on gem5.org,
http://www.gem5.org/M5ops#The_m5_Utility_.28FS_mode.29
but m5 utility seems not support it any more?

????: Re: [gem5-users] Switch CPU model
For fs.py, use m5 checkpoint + gem5.opt fs.py -r 1, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/39762d2f158789a399a2ef962703c43a5339f308#gem5-run-benchmark
I don't konw what switchcpu is meant to do.

Hi, All
I just want to switch my CPU model to O3 detail after I boot up my ubuntu and
before I call the benchmark.
and I found one of ways making this is
/sbin/m5 switchcpu; mybechmark_run
Then I can switch cpu with this
if exit_event.getCause() == "switchcpu":
system.switchCpus(system.cpu, system.O3Cpu)
But I found it is not work in m5, the switchcpu is no longer in m5 now?
Is there any particular reason m5 do not support this op any more? Or there is
a better way doing switch cpu?
Thanks.
