函数名称:This is used to send an IPI with no shorthand notation (the destination is* specified in bits 56 to 63 of the ICR).

函数原型:void __default_send_IPI_dest_field(unsigned int mask, int vector, unsigned int dest)

返回类型:void

参数:

类型参数名称
unsigned intmask
intvector
unsigned intdest
152  如果此条件成立可能性小(为编译器优化)(vector == Linux IRQ vector layout)则safe_apic_wait_icr_idle()
154  否则__xapic_wait_icr_idle()
160  cfg等于__prepare_ICR2(mask)
161  native_apic_mem_write(APIC_ICR2, cfg)
166  cfg等于__prepare_ICR(0, vector, dest)
171  native_apic_mem_write(APIC_ICR, cfg)
