Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_gpu_virtual_address_range_and_stride)

D3D12DDI_GPU_VIRTUAL_ADDRESS_RANGE_AND_STRIDE structure

Description

Describes the GPU virtual address range and stride.

Members

`StartAddress`

The beginning of a virtual address range.

`SizeInBytes`

The size of the virtual address, in bytes.

`StrideInBytes`

Defines indexing stride, such as for vertices. Only the bottom 32 bits get used. The field is 64-bits purely to make alignment of containing structures clean/obvious everywhere.

Remarks

Used in the D3D12DDIARG_DISPATCH_RAYS_0054 structure.
