82 Module Documentation Maps the count Direct3D resources in ppResources for access by CUDA. The resources in ppResources may be accessed in CUDA kernels until they are unmapped. Direct3D should not access any resources while they are mapped by CUDA. If an application does so, the results are undefined. This function provides the synchronization guarantee that any Direct3D calls issued before cudaD3D10MapResources() will complete before any CUDA kernels issued after cudaD3D10MapResources() begin. If any of ppResources have not been registered for use with CUDA or if ppResources contains any duplicate entries then cudaErrorInvalidResourceHandle is returned. If any of ppResources are presently mapped for access by CUDA then cudaErrorUnknown is returned. Parameters: count - Number of resources to map for CUDA ppResources - Resources to map for CUDA Returns: Note: See also: cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknown Note that this function may also return error codes from previous, asynchronous launches. cudaGraphicsMapResources 4.14.2.2 cudaError_t cudaD3D10RegisterResource (ID3D10Resource ∗ pResource, unsigned int flags) Deprecated This function is deprecated as of Cuda 3.0. Registers the Direct3D resource pResource 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 cudaD3D10UnregisterResource(). Also on success, this call will increase the internal reference count on pResource. This reference count will be decremented when this resource is unregistered through cudaD3D10UnregisterResource(). This call is potentially high-overhead and should not be called every frame in interactive applications. The type of pResource must be one of the following: • ID3D10Buffer: Cannot be used with flags set to cudaD3D10RegisterFlagsArray. • ID3D10Texture1D: No restrictions. • ID3D10Texture2D: No restrictions. • ID3D10Texture3D: No restrictions. The flags argument specifies the mechanism through which CUDA will access the Direct3D resource. The following values are allowed. Generated for NVIDIA CUDA Library by Doxygen
4.14 Direct3D 10 Interoperability [DEPRECATED] 83 • cudaD3D10RegisterFlagsNone: Specifies that CUDA will access this resource through a void∗. The pointer, size, and pitch for each subresource of this resource may be queried through cudaD3D10ResourceGetMappedPointer(), cudaD3D10ResourceGetMappedSize(), and cudaD3D10ResourceGetMappedPitch() respectively. This option is valid for all resource types. • cudaD3D10RegisterFlagsArray: Specifies that CUDA will access this resource through a CUarray queried on a sub-resource basis through cuD3D10ResourceGetMappedArray(). This option is only valid for resources of type ID3D10Texture1D, ID3D10Texture2D, and ID3D10Texture3D. 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. If Direct3D interoperability is not initialized on this context then cudaErrorInvalidDevice is returned. If pResource is of incorrect type or is already registered then cudaErrorInvalidResourceHandle is returned. If pResource cannot be registered then cudaErrorUnknown is returned. Parameters: pResource - Resource to register flags - Parameters for resource registration Returns: Note: cudaSuccess, cudaErrorInvalidDevice, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown See also: Note that this function may also return error codes from previous, asynchronous launches. cudaGraphicsD3D10RegisterResource 4.14.2.3 cudaError_t cudaD3D10ResourceGetMappedArray (cudaArray ∗∗ ppArray, ID3D10Resource ∗ pResource, unsigned int subResource) Deprecated This function is deprecated as of Cuda 3.0. Returns in ∗ppArray an array through which the subresource of the mapped Direct3D resource pResource which corresponds to subResource may be accessed. The value set in ppArray may change every time that pResource is mapped. If pResource is not registered, then cudaErrorInvalidResourceHandle is returned. If pResource was not registered with usage flags cudaD3D10RegisterFlagsArray, then cudaErrorInvalidResourceHandle is returned. If pResource is not mapped then cudaErrorUnknown is returned. For usage requirements of the subResource parameter, see cudaD3D10ResourceGetMappedPointer(). Generated for NVIDIA CUDA Library by Doxygen
