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`` 。

18 asymmetric CPU capacity systems, as they contain CPUs of different capacities.
20 Disparity in maximum attainable performance (IOW in maximum CPU capacity) stems
36 capacity(cpu) = work_per_hz(cpu) * max_freq(cpu)
41 Two different capacity values are used within the scheduler. A CPU's
42 ``original capacity`` is its maximum attainable capacity, i.e. its maximum
43 attainable performance level. This original capacity is returned by
44 the function arch_scale_cpu_capacity(). A CPU's ``capacity`` is its ``original
45 capacity`` to which some loss of available performance (e.g. time spent
