ipi_send

函数名称：pi_send_mask - Send an IPI to target CPU(s)*@virq: linux irq number from irq_reserve_ipi()*@dest: dest CPU(s), must be a subset of the mask passed to* irq_reserve_ipi()* Returns zero on success and negative error number on failure.

函数原型：int ipi_send_mask(unsigned int virq, const struct cpumask *dest)

返回类型：int

参数：

类型	参数	名称
unsigned int	virq
const struct cpumask *	dest

desc等于中断转换为描述

331

struct irq_data * data = desc ? irq_desc_get_irq_data(desc) : NULL

332

struct irq_chip * chip = data ? irq_data_get_irq_chip(data) : NULL

334

如果WARN_ON_ONCE(ipi_send_verify(chip, data, dest, 0))则返回:负EINVAL

337

返回: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
