函数名称：numachip_send_IPI_one

函数原型：static void numachip_send_IPI_one(int cpu, int vector)

返回类型：void

参数：

类型参数名称
intcpu
intvector
96  apicid等于per_cpu(Map cpu index to physical APIC ID, cpu)
99  禁止抢占()
100  local_apicid等于Operations for contexts that are safe from preemption/interrupts. These* operations verify that preemption is disabled.(Map cpu index to physical APIC ID)
103  如果非apicid按位异或local_apicid的值右移NUMACHIP_LAPIC_BITS位的值则
106  local_irq_save(flags)
107  This is used to send an IPI with no shorthand notation (the destination is* specified in bits 56 to 63 of the ICR).
109  local_irq_restore(flags)
110  禁用抢占和中断()
111  返回
113  禁用抢占和中断()
115  dmode等于如果vector恒等于Linux IRQ vector layout则APIC_DM_NMI否则APIC_DM_FIXED
116  numachip_apic_icr_write(apicid, dmode | vector)
