SlotPath - | the slot path from the root bus to the device; represented as a null- |
| terminated character string |
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:
Attributes from VendorID to HeaderType represent the PCI configuration space attributes of the device with the same names.
The field NeedsReset has a special meaning. It is set to RESET_REQUIRED or UNKNOWN before the callback is called. The callback should set this field to RESET_NOT_REQUIRED or RESET_REQUIRED on return.
The callback should set this field to RESET_NOT_REQUIRED if it considers that no reset is necessary for this device before releasing the bus lock (for example, if the device can be set to a safe state by the device driver or is in a safe state already).
The callback should set this field to RESET_REQUIRED if it considers that the reset is necessary for the device.
No descriptors are submitted for empty slots or for the slots occupied by devices that the infrastructure considers safe for the host.
If a
The actions of the infrastructure after the callback returns are specified by the following rules:
•If the parameter SlotResetSupported = FALSE (the infrastructure does not support
•Otherwise, for each physical slot in the domain, if SlotResetSupported = TRUE, and there is a descriptor for the given physical slot in the array with NeedsReset = RESET_REQUIRED, this physical slot is reset.
•Otherwise, if there is a
As a consequence, there is no reset if the callback clears NeedsReset in all descriptors submitted to it.
