DXGK_BUILDPAGINGBUFFER_TRANSFERVIRTUAL structure (d3dkmddi.h)
DXGK_BUILDPAGINGBUFFER_TRANSFERVIRTUAL is used as part of an allocation transfer operation.

HANDLE hAllocation;
UINT64 AllocationOffsetInBytes;
UINT64 TransferSizeInBytes;
D3DGPU_VIRTUAL_ADDRESS SourceVirtualAddress;
D3DGPU_VIRTUAL_ADDRESS DestinationVirtualAddress;

D3DGPU_VIRTUAL_ADDRESS DestinationPageTable;
} DXGK_BUILDPAGINGBUFFER_TRANSFERVIRTUAL;
Members
hAllocation
Kernel mode driver handle of the transferred allocation content. The handle is returned from DxgkDdiCreateAllocation. The allocation properties are needed to perform special transfers (as swizzle, de-swizzle, etc.).
AllocationOffsetInBytes
The offset in bytes from the start of the allocation being transferred. The offset should not be added to SourceVirtualAddress or DesinationVirtualAddress.
TransferSizeInBytes
The number of bytes to transfer.
SourceVirtualAddress
The virtual address of the source in the context of the paging process.
DestinationVirtualAddress
The virtual address of the destination in the context of the paging process.
SourcePageTable
The GPU virtual address of the page table that is used to map the SourceVirtualAddress address.
TransferDirection
The DXGK_MEMORY_TRANSFER_DIRECTION structure describing the operation.
Flags
The DXGK_TRANSFERVIRTUALFLAGS structure describing the operation.
DestinationPageTable
The GPU virtual address of the page table that is used to map the DestinationVirtualAddress address. The address is valid only when the DXGK_GPUMMUCAPS.LegacyBehaviors.SourcePageTableVaInTransfer cap is set.
