| 141 | Description: | ||
| 142 | When the appropriate driver is loaded, it will create a | ||
| 143 | directory per claimed physical PCI slot in | ||
| 144 | /sys/bus/pci/slots/. The names of these directories are | ||
| 145 | specific to the driver, which in turn, are specific to the | ||
| 146 | platform, but in general, should match the label on the | ||
| 147 | machine's physical chassis. | ||
| 148 | |||
| 149 | The drivers that can create slot directories include the | ||
| 150 | PCI hotplug drivers, and as of 2.6.27, the pci_slot driver. | ||
| 151 | |||
| 152 | The slot directories contain, at a minimum, a file named | ||
| 153 | 'address' which contains the PCI bus:device:function tuple. | ||
| 154 | Other files may appear as well, but are specific to the | ||
| 155 | driver. | ||

| 162 | If PCI slot directories (as described above) are created, | ||
| 163 | and the physical slot is actually populated with a device, | ||
| 164 | symbolic links in the slot directory pointing to the | ||
| 165 | device's PCI functions are created as well. | ||
