QNX SDP 7 includes a new PCI server, and you must update your code to use the new server and its API. For more information, see the PCI Server User's Guide. The general steps are the same as with the old API, and the documentation includes a sample program that should help you get started.
The pci utility has been replaced by pci-tool. The output of pci-tool is different from that of pci. For example, pci reported the idx value normalized to specific devices (i.e., specific vendor and device IDs), but pci-tool displays an idx value for each device that it finds, based on the current search criteria. If the search criteria changes, the same device (BDF) may be found at a different idx value. The format that pci-tool uses may initially be confusing to those familiar with the old pci utility.
