Hi all, I found Gem5 provides DVFS support for ARM. The doc<https://www.gem5.org/documentation/learning_gem5/part2/arm_dvfs_support/> introduce how to enable it in the FS mode but not clearly about how it works. From my study with the Gem5 source code, energy_ctrl will call DVFS to change the voltage or Frequency domain according to the incoming packet. But I have no idea where the incoming packets from and how it works? Beside I want know that if it is possible to enable the DVFS in the SE mode? Since the energy_ctrl is a pio device, maybe it is impossible to work in the SE mode?
Thanks + regards, Ziyang
