H A Dsched-energy.rst9 the impact of its decisions on the energy consumed by CPUs. EAS relies on an
10 Energy Model (EM) of the CPUs to select an energy efficient CPU for each task,

25 please refer to its documentation (see Documentation/power/energy-model.rst).
32 - energy = [joule] (resource like a battery on powered devices)
33 - power = energy/time = [joule/second] = [watt]
35 The goal of EAS is to minimize energy, while still getting the job done. That
