Hi Ali, You can ignore this warning at the beginning of simulation. The warning is pretty self-explanatory. After adding some power modeling information to gem5, there is a warning if you change power states more than once at the same moment (which is physically impossible). But since this is at the beginning of simulation, it isn't modeling something real, so you can ignore this error.
We should probably do something to ignore this warning at the beginning of simulation.
