3 Porting a BSP to Custom Hardware

3.3 Finalizing Your BSP

#ifdef INCLUDE_PCI

sysPciAutoConfig ();

/* prepare BSP support for callouts from supported END driver */

#if defined(INCLUDE_END) && defined(INCLUDE_FEI_END)

sys557PciInit ();

#endif /* defined(INCLUDE_END) && defined(INCLUDE_FEI_END) */

#endif /* INCLUDE_PCI */

To include the PCI support code, #include sysBusPci.c from sysLib.c. As with the

call to sysPciAutoConfig( ), the #include sysBusPci.c line should be surrounded

by #ifdef

INCLUDE_PCI and #endif.

PCI Show Routines

VxWorks provides several utilities to display information about devices on the PCI

bus. These show routines can be used to help diagnose problems with PCI

configuration and driver development.

pciConfigTopoShow( )

The routine pciConfigTopoShow( ) was introduced in VxWorks 5.5. This routine

provides a readable format display of all devices on the PCI bus. For each device,

some basic configuration information is displayed. This includes the

[bus, device, function] tuple, the device type in an alphanumeric format, the

command and status words, and the base address register (BAR) addresses.

Sample output for this routine is as follows:

-> pciConfigTopoShow

[0,0,0] type=UNKNOWN (0x80) BRIDGE

status=0x02b0 ( CAP 66MHZ FBTB DEVSEL=1 )
