函数名称：pi_send_mask - send an IPI to target Linux SMP CPU(s)*@desc: pointer to irq_desc of the IRQ*@dest: dest CPU(s), must be a subset of the 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_mask(struct irq_desc *desc, const struct cpumask *dest)

返回类型：int

参数：

类型参数名称
struct irq_desc *desc
const struct cpumask *dest
265  data等于irq_desc_get_irq_data(desc)
266  chip等于irq_data_get_irq_chip(data)
278  如果ipi_send_mask则
279  ipi_send_mask(data, dest)
280  返回:0
283  如果irq_domain_is_ipi_per_cpu(硬件中断对象)则
284  base等于中断号
287  irq等于base加cpu减ipi_offset
289  data等于irq_get_irq_data(irq)
290  ipi_send_single(data, cpu)
292  否则
293  遍历CPU(cpu, dest)
294  ipi_send_single(data, cpu)
296  返回:0
