HwDmaStarted

PVOID HwDmaStarted(HwDeviceExtension)
IN PVOID  HwDeviceExtension;
 

If the adapter uses slave DMA, the miniport driver's HwDmaStarted routine is called after the system DMA controller has been set up for a DMA transfer.

HwDeviceExtension

Points to the miniport driver's storage for per-adapter data.

Miniport drivers of host adapters that are busmasters or use programmed I/O need not supply this routine.
