Hi, You will need some extensive characterization (and measurement) of the core power w.r.t the CPU frequency and the C-state residencies. You could create a table of the power consumption based on the core frequency; and then individual residencies at that frequency; you should discount all the state beyond the C-state for the CPU when clock gating comes into effect, if your core supports clock gating at all. Say for example, running at the lowest frequency constrained to a 100% CPU utilization might be the number for starters.
