Detailed Description

       This section describes the Direct3D 10 interoperability functions of the CUDA runtime
       application programming interface. Note that mapping of Direct3D 10 resources is performed
       with the graphics API agnostic, resource mapping interface described in Graphics
       Interopability.

Function Documentation

   cudaError_t cudaD3D10GetDevice (int * device, IDXGIAdapter * pAdapter)
       Returns in *device the CUDA-compatible device corresponding to the adapter pAdapter
       obtained from IDXGIFactory::EnumAdapters. This call will succeed only if a device on
       adapter pAdapter is CUDA-compatible.

       Parameters:
           device - Returns the device corresponding to pAdapter
           pAdapter - D3D10 adapter to get device for

       Returns:
           cudaSuccess, cudaErrorInvalidValue, cudaErrorUnknown

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

       See also:
           cudaGraphicsD3D10RegisterResource, cuD3D10GetDevice

   cudaError_t cudaD3D10GetDevices (unsigned int * pCudaDeviceCount, int * pCudaDevices, unsigned
       int cudaDeviceCount, ID3D10Device * pD3D10Device, enum cudaD3D10DeviceList deviceList)
       Returns in *pCudaDeviceCount the number of CUDA-compatible devices corresponding to the
       Direct3D 10 device pD3D10Device. Also returns in *pCudaDevices at most cudaDeviceCount of
       the the CUDA-compatible devices corresponding to the Direct3D 10 device pD3D10Device.

       If any of the GPUs being used to render pDevice are not CUDA capable then the call will
       return cudaErrorNoDevice.

       Parameters:
           pCudaDeviceCount - Returned number of CUDA devices corresponding to pD3D10Device
           pCudaDevices - Returned CUDA devices corresponding to pD3D10Device
           cudaDeviceCount - The size of the output device array pCudaDevices
           pD3D10Device - Direct3D 10 device to query for CUDA devices
           deviceList - The set of devices to return. This set may be cudaD3D10DeviceListAll for
           all devices, cudaD3D10DeviceListCurrentFrame for the devices used to render the
           current frame (in SLI), or cudaD3D10DeviceListNextFrame for the devices used to render
           the next frame (in SLI).

       Returns:
           cudaSuccess, cudaErrorNoDevice, cudaErrorUnknown

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.

   cudaError_t cudaGraphicsD3D10RegisterResource (struct cudaGraphicsResource ** resource,
       ID3D10Resource * pD3DResource, unsigned int flags)
       Registers the Direct3D 10 resource pD3DResource for access by CUDA.

       If this call is successful, then the application will be able to map and unmap this
       resource until it is unregistered through cudaGraphicsUnregisterResource(). Also on
       success, this call will increase the internal reference count on pD3DResource. This
       reference count will be decremented when this resource is unregistered through
       cudaGraphicsUnregisterResource().

       This call potentially has a high-overhead and should not be called every frame in
       interactive applications.

       The type of pD3DResource must be one of the following.

       • ID3D10Buffer: may be accessed via a device pointer

       • ID3D10Texture1D: individual subresources of the texture may be accessed via arrays

       • ID3D10Texture2D: individual subresources of the texture may be accessed via arrays

       • ID3D10Texture3D: individual subresources of the texture may be accessed via arrays

       The flags argument may be used to specify additional parameters at register time. The
       valid values for this parameter are

       • cudaGraphicsRegisterFlagsNone: Specifies no hints about how this resource will be used.

       • cudaGraphicsRegisterFlagsSurfaceLoadStore: Specifies that CUDA will bind this resource
         to a surface reference.

       • cudaGraphicsRegisterFlagsTextureGather: Specifies that CUDA will perform texture gather
         operations on this resource.

       Not all Direct3D resources of the above types may be used for interoperability with CUDA.
       The following are some limitations.

       • The primary rendertarget may not be registered with CUDA.

       • Resources allocated as shared may not be registered with CUDA.

       • Textures which are not of a format which is 1, 2, or 4 channels of 8, 16, or 32-bit
         integer or floating-point data cannot be shared.

       • Surfaces of depth or stencil formats cannot be shared.

       A complete list of supported DXGI formats is as follows. For compactness the notation
       A_{B,C,D} represents A_B, A_C, and A_D.

       • DXGI_FORMAT_A8_UNORM

       • DXGI_FORMAT_B8G8R8A8_UNORM

       • DXGI_FORMAT_B8G8R8X8_UNORM

       • DXGI_FORMAT_R16_FLOAT

       • DXGI_FORMAT_R16G16B16A16_{FLOAT,SINT,SNORM,UINT,UNORM}

       • DXGI_FORMAT_R16G16_{FLOAT,SINT,SNORM,UINT,UNORM}

       • DXGI_FORMAT_R16_{SINT,SNORM,UINT,UNORM}

       • DXGI_FORMAT_R32_FLOAT

       • DXGI_FORMAT_R32G32B32A32_{FLOAT,SINT,UINT}

       • DXGI_FORMAT_R32G32_{FLOAT,SINT,UINT}

       • DXGI_FORMAT_R32_{SINT,UINT}

       • DXGI_FORMAT_R8G8B8A8_{SINT,SNORM,UINT,UNORM,UNORM_SRGB}

       • DXGI_FORMAT_R8G8_{SINT,SNORM,UINT,UNORM}

       • DXGI_FORMAT_R8_{SINT,SNORM,UINT,UNORM}

       If pD3DResource is of incorrect type or is already registered, then
       cudaErrorInvalidResourceHandle is returned. If pD3DResource cannot be registered, then
       cudaErrorUnknown is returned.

       Parameters:
           resource - Pointer to returned resource handle
           pD3DResource - Direct3D resource to register
           flags - Parameters for resource registration

       Returns:
           cudaSuccess, cudaErrorInvalidDevice, cudaErrorInvalidValue,
           cudaErrorInvalidResourceHandle, cudaErrorUnknown

       Note:
           Note that this function may also return error codes from previous, asynchronous
           launches.
