PVOID
HwScsiDmaStarted(
IN PVOID HwDeviceExtension
);
If the HBA is a slave DMA device, the miniport driver's HwScsiDmaStarted routine is called after the OS-specific port driver has set up the system DMA controller for a DMA transfer.
Parameters
HwDeviceExtension
Points to the miniport driver's per-HBA storage area.
Comments
Only miniport drivers of slave DMA adapters must have a HwScsiDmaStarted routine.
HwScsiDmaStarted is responsible for programming the HBA for the transfer operation.
Miniport drivers of HBAs that are busmasters or use programmed I/O do not supply this routine.
