SlotPath | The slot path from the root bus to the device. The slot path is stored as a |
| |
| one item of the slot path and represents the number (DeviceNumber * 8 |
| + FunctionNumber) for the corresponding |
| hexadecimal. The two hexadecimal digits of this number are represented |
| by two characters from the set ‘0’..’9’, ‘A’..’F’. |
BusNumber | The bus number for the device. This value is 16 bit to accommodate |
| possible future extensions to PCI that allow more than 256 PCI buses in |
| the system |
DeviceNumber | The device number for the device |
FunctionNumber | The function number for the device |
Device configuration attributes (all based on PCI configuration space attributes):
VendorID/DeviceID/RevisionID
Identifies the manufacturer of the device that provides the PCI interface for the slot, the specific device product among those made by that manufacturer, and the revision level of that device.
SubsystemVendorID/SubsystemID
Identifies the manufacturer of the board and the specific board product among those made by that manufacturer.
BaseClass/SubClass/ProgIF
Identifies the type of device and its programming interface
HeaderType - | Identifies the layout of the second part of the |
| device that provides the PCI interface for the slot (for example, 0 for |
| conventional PCI device, 1 for |
The field NeedsReset indicates whether this device in its current state needs to be reset if switchover takes place. The value RESET_NOT_REQUIRED in this field means one of the following things:
•The device is already prepared for switchover.
•The device is not in use.
•The driver for the device is
The value UNKNOWN means that the infrastructure does not know whether or not the device needs reset.
