It uses EEMBC CoreMark [2] as the workload and measures power usage using the PM8150B PMIC's fuel gauge. 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. An Asus ZenFone 6 device running a downstream Qualcomm 4.14 kernel (LA.UM.8.1.r1-15600-sm8150.0) was used for benchmarks to ensure proper frequency scaling and other low-level controls. Raw benchmark results can be found in the freqbench repository [3].
