AtaPortDeviceReady function

Description

The AtaPortDeviceReady routine informs the port driver that the indicated device is ready to accept new requests.

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.

Parameters

ChannelExtension [in]

A 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.

Remarks

The port driver resumes the paused request queue for the indicated device. If the caller assigns a wildcard value of IDE_UNTAGGED to parameters TargetId and Lun, the port driver will restart the channel request queue.
