This article mainly introduces the use of vxBusShow in vxworks, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

VxWorks introduced vxBus, a new device driver framework, from 6. 2. VxBus makes the addition of new devices and drivers more flexible, and the coupling between drivers and BSP is lower. And support more buses # 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 * /

Today we will only look at one function, vxBusShow (), which will show four pieces of information.

1 the bus currently registered by the system

2 of course, the driver for system registration

3 device instances on each bus

4 there are no devices loaded with drivers on each bus
