函数名称：__inquire_remote_apic

函数原型：void __inquire_remote_apic(int apicid)

返回类型：void

参数：

类型参数名称
intapicid
665  unsigned i, regs[] = {APIC_ID >> 4, APIC_LVR >> 4, APIC_SPIV >> 4}
666  const char * const names[] = {"ID", "VERSION", "SPIV"}
670  打印信息("Inquiring remote APIC 0x%x...\n", apicid)
672  以i小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(regs)循环
673  打印信息("... APIC 0x%x %s: ", apicid, names[i])
678  status等于safe_apic_wait_icr_idle()
679  如果status则打印标准信息("a previous APIC delivery may have failed\n")
682  apic_icr_write(APIC_DM_REMRD | regs[i], apicid)
684  timeout等于0
685  循环
686  0x10c7 is 2**32 / 1000000 (rounded up) (100)
687  status等于apic_read(APIC_ICR)按位与APIC_ICR_RR_MASK
688  当status恒等于APIC_ICR_RR_INPROG且timeout自加小于1000循环
691  当:status恒等于APIC_ICR_RR_VALID
692  status等于apic_read(APIC_RRR)
693  打印标准信息("%08x\n", status)
694  退出
695  默认
696  打印标准信息("failed\n")
