Constants

D3DDDI_UPDATEGPUVIRTUALADDRESS_MAP

Maps the given virtual address range to the given allocation range. The allocation does not have to be resident at the time of submission or at the time of mapping. The read-write protection is set to the pages. DriverProtection for the pages is set to zero.

D3DDDI_UPDATEGPUVIRTUALADDRESS_UNMAP

Puts the specified virtual address range to the zero state or to the invalid state.

D3DDDI_UPDATEGPUVIRTUALADDRESS_COPY

The copy operation copies all mappings from source GPU virtual address range to the destination range. The source and destination ranges are allowed to intersect. Both ranges must belong to a reserved (zero) virtual address range.
