Dsched-capacity.rst47 调度器使用了两种不同的算力值。CPU的 ``capacity_orig`` 是它的最大可达算力,即最大可达性能等级。
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`` 。

Dsched-capacity.rst42 ``capacity_orig`` is its maximum attainable capacity, i.e. its maximum
43 attainable performance level. A CPU's ``capacity`` is its ``capacity_orig`` to
48 while ``capacity_orig`` is class-agnostic. The rest of this document will use
49 the term ``capacity`` interchangeably with ``capacity_orig`` for the sake of
