27 我们引入CPU算力(capacity)的概念来测量每个CPU能达到的性能,它的值相对系统中性能最强的CPU
42 capacity(cpu) = work_per_hz(cpu) * max_freq(cpu)
48 CPU的 ``capacity`` 是 ``capacity_orig`` 扣除了一些性能损失(比如处理中断的耗时)的值。
50 注意CPU的 ``capacity`` 仅仅被设计用于CFS调度类,而 ``capacity_orig`` 是不感知调度类的。为
51 简洁起见,本文档的剩余部分将不加区分的使用术语 ``capacity`` 和 ``capacity_orig`` 。
67 - capacity(CPU0) = C
68 - capacity(CPU1) = C/2
98 - capacity(CPU0) = C
99 - capacity(CPU1) = C/3
174 - capacity(CPU0) = C
175 - capacity(CPU1) = C/3
196 task_util_cpu_inv(p) = duty_cycle(p) * (capacity(cpu) / max_capacity)
207 curr_frequency(cpu) capacity(cpu)
235 arch_topology.h的percpu变量cpu_scale),它是从capacity-dmips-mhz CPU binding中衍生计算
236 出来的。参见Documentation/devicetree/bindings/cpu/cpu-capacity.txt。
261 capacity C/2 C
302 task_util(p) < capacity(task_cpu(p))
318 clamp(task_util(p), task_uclamp_min(p), task_uclamp_max(p)) < capacity(cpu)
336 capacity(CPU0) = C
337 capacity(CPU1) = C / 3
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
374 task_uclamp_min(p) <= capacity(task_cpu(cpu))
387 task_bandwidth(p) < capacity(task_cpu(p))
