| === Description |
| |
| This extension adds a new query to obtain PCI bus information about a |
| physical device. |
| |
| Not all physical devices have PCI bus information, either due to the device |
| not being connected to the system through a PCI interface or due to platform |
| specific restrictions and policies. |
| Thus this extension is only expected to be supported by physical devices |
| which can provide the information. |
| |
| As a consequence, applications should always check for the presence of the |
| extension string for each individual physical device for which they intend |
| to issue the new query for and should not have any assumptions about the |
| availability of the extension on any given platform. |
