p The .Nm provides a two-level view of devices. At the highest level, PCI devices themselves are named, according to their bus, slot and function in the system hierachy. PCI storage devices are listed in the scsi_host class with a device sym-link to the PCI directories of the devices.
p Each device node is a directory containing some files and directories: l -tag -width status t Pa host A place holder for storage
a host information. t Pa pci_id A directory for the
a pci_id that contains either the device information or another directory structure for a PCI bridge. .El
