H A Dirq-domain.rst33 提供任何对控制器本地IRQ(hwirq)号到Linux IRQ号空间的反向映射的支持。
52 irq_domain和一个hwirq号作为参数。 如果hwirq的映射还不存在，那么它将分配
73 如在irq_chip回调中），那么可以直接从irq_data->hwirq中获得。
89 线性反向映射维护了一个固定大小的表，该表以hwirq号为索引。 当一个hwirq被映射
90 时，会给hwirq分配一个irq_desc，并将irq号存储在表中。
94 必须尽可能大的hwirq号。
110 irq_domain维护着从hwirq号到Linux IRQ的radix的树状映射。 当一个hwirq被映射时，
111 一个irq_desc被分配，hwirq被用作radix树的查找键。
113 如果hwirq号可以非常大，树状映射是一个很好的选择，因为它不需要分配一个和最大hwirq
114 号一样大的表。 缺点是，hwirq到IRQ号的查找取决于表中有多少条目。
