PHW_DMA_STARTED callback

Description

The PHW_DMA_STARTED routine prototype declares a SCSI miniport driver routine that starts DMA for subordinate DMA device.

Parameters

DeviceExtension [in]

Pointer to the miniport driver's per-HBA storage area.

Remarks

If the HBA is a subordinate DMA device, the SCSI miniport driver's HwScsiDmaStarted routine is called after the OS-specific port driver has set up the system DMA controller for a DMA transfer.

Miniport drivers that work with the StorPort driver do not support adapters that require subordinate DMA.
