View the official Windows Driver Kit DDI referenceNo description available.
The AtaPortInitializeQueueTag routine initializes the queue tag list for the specified device.
Note The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.
DeviceExtensionA pointer to the channel extension.
TargetId [in]Specifies the target identifier of the device.
Lun [in]Specifies the logical unit number (LUN) of the device.
MaxQueueTag [in]Specifies the maximum allowed value for the queue tag.
AtaPortInitializeQueueTag returns TRUE if the operation succeeds. Otherwise, it returns FALSE.
The miniport driver should call AtaPortInitializeQueueTag before it uses AtaPortAllocateQueueTag and AtaPortReleaseQueueTag to allocate and release queue tags respectively.
The values in the TargetId and Lun parameters specify the device to which the queue tag belongs. To generate channel specific queue tags, the miniport driver should set the TargetId and Lun parameters to IDE_UNTAGGED.
