A Dirq-domain.rst12 irq_domain 中断号映射库
36 irq_domain来管理映射。
41 irq_domain的用法
64 irq_domain映射的类型
180 个irq_domain数据结构，并将这些irq_domain组织成层次结构。
182 在建立irq_domain层次结构时，靠近设备的irq_domain为子域，靠近CPU的
186 CPU Vector irq_domain (root irq_domain to manage CPU vectors)
203 1) 一个新的字段 'parent' 被添加到irq_domain结构中；它用于维护irq_domain的层次信息。
205 匹配irq_domain层次结构。irq_data用于存储irq_domain指针和硬件irq号。

233 When building irq_domain hierarchy, the irq_domain near to the device is
237 CPU Vector irq_domain (root irq_domain to manage CPU vectors)
243 IOAPIC irq_domain (manage IOAPIC delivery entries/pins)
245 There are four major interfaces to use hierarchy irq_domain:
