The energy model dynamic-power-coefficient values were calculated with DPC = µW / MHz / V^2 for each OPP, and averaged across all OPPs within each cluster for the final coefficient. Voltages were obtained from the qcom-cpufreq-hw driver that reads voltages from the OSM LUT programmed into the SoC. Normalized DMIPS/MHz capacity scale values for each CPU were calculated from CoreMarks/MHz (CoreMark iterations per second per MHz), which serves the same purpose. For each CPU, the final capacity-dmips-mhz value is the C/MHz value of its maximum frequency normalized to SCHED_CAPACITY_SCALE (1024) for the fastest CPU in the system. For more details on measurement process see the commit message for the commit 6aabed5526ee ("arm64: dts: qcom: sm8250: Add CPU capacities and energy model").
