函数原型：int irq_set_vcpu_affinity(unsigned int irq, void *vcpu_info)

返回类型：int

参数：

类型参数名称
unsigned intirq
void *vcpu_info
463  desc等于irq_get_desc_lock(irq, & flags, 0)
466  ret等于负ENOSYS
468  如果非desc则返回:负EINVAL
471  data等于irq_desc_get_irq_data(desc)
472  循环
473  chip等于irq_data_get_irq_chip(data)
474  如果chip且irq_set_vcpu_affinity则退出
479  data = NULL
481  当data循环
483  如果data则ret等于irq_set_vcpu_affinity(data, vcpu_info)
485  irq_put_desc_unlock(desc, flags)
487  返回:ret
