+---------------------------------------------------------------------
+何为 IRQ?
+
+一个 IRQ 是来自某个设备的一个中断请求。目前,它们可以来自一个硬件引脚,
+或来自一个数据包。多个设备可能连接到同个硬件引脚,从而共享一个 IRQ。
+
+一个 IRQ 编号是用于告知硬件中断源的内核标识。通常情况下,这是一个
+全局 irq_desc 数组的索引,但是除了在 linux/interrupt.h 中的实现,
+具体的细节是体系结构特定的。
+
+一个 IRQ 编号是设备上某个可能的中断源的枚举。通常情况下,枚举的编号是
+该引脚在系统内中断控制器的所有输入引脚中的编号。对于 ISA 总线中的情况,
+枚举的是在两个 i8259 中断控制器中 16 个输入引脚。
+
+架构可以对 IRQ 编号指定额外的含义,在硬件涉及任何手工配置的情况下,
+是被提倡的。ISA 的 IRQ 是一个分配这类额外含义的典型例子。
