DMA remapping support in Storport miniport drivers

The StorAhci Storport miniport driver sample code shows how to support DMA remapping in a Storport miniport driver. For additional information about DMA remapping and Kernel DMA Protection, see Enabling DMA Remapping for device drivers.

Note

For Storport miniport drivers, the default value of "DMA remapping policy" device property described in Validating that DMA Remapping is enabled for a specific device driver instance is 0 for Windows 10 versions 1803 and 1809, and 2 for Windows 10 version 1903 and later.

This property corresponds to DEVPKEY_Device_DmaRemappingPolicy.
