H A Dfair.c801 * based on the cfs_rq's current util_avg:
803 * util_avg = cfs_rq->util_avg / (cfs_rq->load_avg + 1) * se.load.weight
805 * However, in many cases, the above util_avg does not give a desired
809 * To solve this problem, we also cap the util_avg of successive tasks to
812 * util_avg_cap = (cpu_scale - cfs_rq->avg.util_avg) / 2^n
819 * task util_avg: 512, 256, 128, 64, 32, 16, 8, ...
820 * cfs_rq util_avg: 512, 768, 896, 960, 992, 1008, 1016, ...
822 * Finally, that extrapolated util_avg is clamped to the cap (util_avg_cap)
