函数名称:do_IRQ handles all normal device IRQ's (the special* SMP cross-CPU interrupts have their own specific* handlers).
函数原型:__visible unsigned int __irq_entry do_IRQ(struct pt_regs *regs)
返回类型:unsigned int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct pt_regs * | regs |
235 | old_regs等于set_irq_regs(regs) |
240 | entering_irq() |
245 | desc等于Operations for contexts that are safe from preemption/interrupts. These* operations verify that preemption is disabled.(vector_irq[vector]) |
246 | 如果此条件成立可能性大(为编译器优化)(!是错误或空)则 |
251 | 否则 |
252 | ack_APIC_irq() |
254 | 如果desc恒等于VECTOR_UNUSED则 |
255 | pr_emerg_ratelimited("%s: %d.%d No irq handler for vector\n", __func__, 当前cpu ID(), vector) |
258 | 否则 |
263 | exiting_irq() |
265 | set_irq_regs(old_regs) |
266 | 返回:1 |
