H A Dirq-domain.rst13 irq_domain 中断号映射库
35 irq_domain 库在 irq_alloc_desc*() API 的基础上增加了 hwirq 和 IRQ 号码
37 irq_domain来管理映射。
39 irq_domain还实现了从抽象的irq_fwspec结构体到hwirq号的转换（到目前为止是
42 irq_domain的用法
45 中断控制器驱动程序通过以下方式创建并注册一个irq_domain。调用
47 同的分配器函数，后面会详细介绍）。 函数成功后会返回一个指向irq_domain的指针。
50 在大多数情况下，irq_domain在开始时是空的，没有任何hwirq和IRQ号之间的映射。
51 通过调用irq_create_mapping()将映射添加到irq_domain中，该函数接受
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
