As Patrick said, to enable DVFS with GEM5 simulation, you have to plug a power model. McPAT can be used to generate power estimates according to the statistics collected from a cycle-accurate simulation with GEM5 (you need also to translate GEM5 output statistics to XML format as required by McPAT). For Dynamic VFS you need to reiterate the loop and simulate changing DVFS after desired number of iterations; GEM5 allows you to stop simulation and then start back again, so you can for sure loop on it.
