      - Configuration space access
        By design, each driver process has read access to the configuration space of the device it's managing, via the libpci and capability module APIs.

        The PCI server (pci-server) is a resource manager process that manages the PCI hierarchy.

Hardware-dependent modules

QNX SDP8.0PCI Server User's GuideAPIConfiguration

A hardware-dependent module is required for providing access to the hardware for every process that uses libpci and capability module APIs, including the pci-server.

Hardware-dependent modules reside in ${QNX_TARGET}/processor/lib/dll/pci/ on your development host, and in /lib/dll/pci/ on your target. Their names are prefixed with pci_hw-. There's use information in each module explaining what it's for and how to use it.

Both the PCI server process and the hardware-dependent module can use a configuration file specified with the PCI_HW_CONFIG_FILE environment variable. The format of this configuration file is documented in ${QNX_TARGET}/processor/etc/system/config/pci/pci_hw-template.cfg (or /etc/system/config/pci/pci_hw-template.cfg on your target system).

In addition to the common sections applicable to all hardware-dependent modules, hardware module developers may choose to define sections specific to a certain hardware module. This may include sections for optional parameters that provide users with the ability to configure or tune the hardware, for dealing with platform variances or for managing out-of-spec behavior or errata. The use information within the hardware-dependent module provides all details pertaining to specific configuration file sections and likely includes a specific hardware configuration file, either because it's required, or as a representative example.
