2. 以序号 3 为例, 记录 3 号显卡 Bus-Id 00000000:CA:00.0

   dmidecode -t slot | grep -i -10 CA:00.0
   Handle 0x000D, DMI type 9, 17 bytes
   System Slot Information
       Designation: CPU SLOT1 PCIe 5.0 X16
       Type: x16 <OUT OF SPEC>
       Current Usage: In Use
       Length: Long
       Characteristics:
               3.3 V is provided
               Opening is shared
