H A Dsched-capacity.rst132 task_util(p) = duty_cycle(p)
148 可以算出 duty_cycle(p) == 25%。
162 task_util_freq_inv(p) = duty_cycle(p) * (curr_frequency(cpu) / max_frequency(cpu))
191 - duty_cycle(p) == 25%，如果任务p在CPU0上按最大频率运行。
192 - duty_cycle(p) == 75%，如果任务p在CPU1上按最大频率运行。
196 task_util_cpu_inv(p) = duty_cycle(p) * (capacity(cpu) / max_capacity)
208 task_util_inv(p) = duty_cycle(p) * ------------------- * -------------
302 task_util(p) < capacity(task_cpu(p))
318 clamp(task_util(p), task_uclamp_min(p), task_uclamp_max(p)) < capacity(cpu)
358 则任务可能变为CPU受限的，也就是说 ``task_util(p) > capacity(task_cpu(p))`` ；CPU算力
