函数名称：__ipi_send_single - send an IPI to a target Linux SMP CPU*@desc: pointer to irq_desc of the IRQ*@cpu: destination CPU, must in the destination mask passed to* irq_reserve_ipi()* This function is for architecture or core code to speed up IPI sending. Not

函数原型：int __ipi_send_single(struct irq_desc *desc, unsigned int cpu)

返回类型：int

参数：

类型参数名称
struct irq_desc *desc
unsigned intcpu
223  data等于irq_desc_get_irq_data(desc)
224  chip等于irq_data_get_irq_chip(data)
235  如果非ipi_send_single则
236  ipi_send_mask(data, cpumask_of - the cpumask containing just a given cpu*@cpu: the cpu (<= nr_cpu_ids)(cpu))
237  返回:0
241  如果irq_domain_is_ipi_per_cpu(硬件中断对象)且cpu不等于ipi_offset则
244  irq等于中断号加cpu减ipi_offset
246  data等于irq_get_irq_data(irq)
