IRQ和GSI在APIC系统中常常被混用,实际上对15以上的IRQ,它和GSI相等。我们在谈到IRQ时,一定要注意它所处的语境。 Vector是CPU的概念,是中断在IDT表中的索引。每个IRQ(或GSI)都对应一个Vector。在PIC模式下,IRQ对应的vector=start vector + IRQ;在APIC模式下,IRQ/GSI的vector由操作系统分配。

kernel: do_IRQ: X.Y No irq handler for vector (irq -1) 网络连接挂起或断开,与上述显示的类似的消息在系统日志中出现。 接口变得不可用,且所有使用该 IP 地址的连接都开始有问题。 我可以从 OS 中检测中断重新映射选项是否在 BIOS 中被禁用了吗?
