VxWorks从6.2开始，引入了vxBus，一种新的设备驱动框架。vxBus使得新设备、新驱动的添加，更为灵活；驱动与BSP的耦合度更低；而且支持更多的总线

#define VXB_BUSID_PLB                   1 /* processor local bus */
#define VXB_BUSID_VME                   2 /* VME */
#define VXB_BUSID_PCI                   3 /* PCI */
#define VXB_BUSID_PCIX                  4 /* PCI w/ PCI-X ext */
#define VXB_BUSID_PCIEXPRESS            5 /* PCI w/ PCI-Express ext */
#define VXB_BUSID_HYPERTRANSPORT        6 /* PCI w/ HyperTransport ext */
#define VXB_BUSID_RAPIDIO               7 /* RapidIO */
#define VXB_BUSID_MII                   8 /* Media Independent Interface */
#define VXB_BUSID_VIRTUAL               9 /* virtual bus */
#define VXB_BUSID_MF                   10 /* multi-function device bus */
#define VXB_BUSID_USB_HOST_EHCI        11 /* EHCI Bus Type */
#define VXB_BUSID_USB_HOST_OHCI        12 /* OHCI Bus Type */
#define VXB_BUSID_USB_HOST_UHCI        13 /* UHCI Bus Type */
#define VXB_BUSID_USB_HUB              14 /* hub bus type */
#define VXB_BUSID_USB_HOST_SYNOPSYSHCI 15 /* Synopsys HCI Bus Type*/
#define VXB_BUSID_USB_HOST_MHCI        16 /* MHCI Bus Type */
#define VXB_BUSID_USB_HOST             17 /* USB Host Bus Type */
#define VXB_BUSID_I2C                  20 /* I2C bus type */
#define VXB_BUSID_SPI                  21 /* Serial Periph Interconnect */
#define VXB_BUSID_SD                   22 /* SD/SDIO bus type */

今天只看一个函数vxBusShow()，它会展示4部分信息

1 当前系统注册的总线
