Function Documentation

__CUDA_DEPRECATED cudaError_t cudaD3D10GetDirect3DDevice (ID3D10Device ** ppD3D10Device)

Deprecated
This function is deprecated as of CUDA 5.0.
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA device with a D3D10 device in order to achieve maximum interoperability performance.
Parameters:
ppD3D10Device - Returns the Direct3D device for this thread
Returns:
cudaSuccess, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.
See also:
cudaD3D10SetDirect3DDevice

__CUDA_DEPRECATED cudaError_t cudaD3D10MapResources (int count, ID3D10Resource ** ppResources)

Deprecated
This function is deprecated as of CUDA 3.0.
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:
cudaSuccess, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED 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 potentially has a high-overhead and should not be called every frame in interactive applications.
The type of pResource must be one of the following:
o ID3D10Buffer: Cannot be used with flags set to cudaD3D10RegisterFlagsArray.
o ID3D10Texture1D: No restrictions.
o ID3D10Texture2D: No restrictions.
o ID3D10Texture3D: No restrictions.
The flags argument specifies the mechanism through which CUDA will access the Direct3D resource. The following values are allowed.
o 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.
o cudaD3D10RegisterFlagsArray: Specifies that CUDA will access this resource through a CUarray queried on a sub-resource basis through cudaD3D10ResourceGetMappedArray(). 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.
o The primary rendertarget may not be registered with CUDA.
o Resources allocated as shared may not be registered with CUDA.
o 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.
o 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:
cudaSuccess, cudaErrorInvalidDevice, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED 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().
Parameters:
ppArray - Returned array corresponding to subresource
pResource - Mapped resource to access
subResource - Subresource of pResource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown
Note:
Note that this function may also return error codes from previous, asynchronous launches.

__CUDA_DEPRECATED cudaError_t cudaD3D10ResourceGetMappedPitch (size_t * pPitch, size_t * pPitchSlice, ID3D10Resource * pResource, unsigned int subResource)

Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pPitch and *pPitchSlice the pitch and Z-slice pitch of the subresource of the mapped Direct3D resource pResource, which corresponds to subResource. The values set in pPitch and pPitchSlice may change every time that pResource is mapped.
The pitch and Z-slice pitch values may be used to compute the location of a sample on a surface as follows.
For a 2D surface, the byte offset of the sample at position x, y from the base pointer of the surface is:
y * pitch + (bytes per pixel) * x
For a 3D surface, the byte offset of the sample at position x, y, z from the base pointer of the surface is:
z* slicePitch + y * pitch + (bytes per pixel) * x
Both parameters pPitch and pPitchSlice are optional and may be set to NULL.
If pResource is not of type ID3D10Texture1D, ID3D10Texture2D, or ID3D10Texture3D, or if pResource has not been registered for use with CUDA, then cudaErrorInvalidResourceHandle is returned. If pResource was not registered with usage flags cudaD3D10RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned. If pResource is not mapped for access by CUDA then cudaErrorUnknown is returned.
For usage requirements of the subResource parameter see cudaD3D10ResourceGetMappedPointer().
Parameters:
pPitch - Returned pitch of subresource
pPitchSlice - Returned Z-slice pitch of subresource
pResource - Mapped resource to access
subResource - Subresource of pResource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

__CUDA_DEPRECATED cudaError_t cudaD3D10ResourceGetMappedPointer (void ** pPointer, ID3D10Resource * pResource, unsigned int subResource)

Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pPointer the base pointer of the subresource of the mapped Direct3D resource pResource which corresponds to subResource. The value set in pPointer 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 cudaD3D9RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned. If pResource is not mapped then cudaErrorUnknown is returned.
If pResource is of type ID3D10Buffer then subResource must be 0. If pResource is of any other type, then the value of subResource must come from the subresource calculation in D3D10CalcSubResource().
Parameters:
pPointer - Returned pointer corresponding to subresource
pResource - Mapped resource to access
subResource - Subresource of pResource to access
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown

Returns in *pSize the size of the subresource of the mapped Direct3D resource pResource which corresponds to subResource. The value set in pSize may change every time that pResource is mapped.
If pResource has not been registered for use with CUDA then cudaErrorInvalidHandle is returned. If pResource was not registered with usage flags cudaD3D10RegisterFlagsNone, then cudaErrorInvalidResourceHandle is returned. If pResource is not mapped for access by CUDA then cudaErrorUnknown is returned.

__CUDA_DEPRECATED cudaError_t cudaD3D10ResourceGetSurfaceDimensions (size_t * pWidth, size_t * pHeight, size_t * pDepth, ID3D10Resource * pResource, unsigned int subResource)

Deprecated
This function is deprecated as of CUDA 3.0.
Returns in *pWidth, *pHeight, and *pDepth the dimensions of the subresource of the mapped Direct3D resource pResource which corresponds to subResource.
Since anti-aliased surfaces may have multiple samples per pixel, it is possible that the dimensions of a resource will be an integer factor larger than the dimensions reported by the Direct3D runtime.
The parameters pWidth, pHeight, and pDepth are optional. For 2D surfaces, the value returned in *pDepth will be 0.
If pResource is not of type ID3D10Texture1D, ID3D10Texture2D, or ID3D10Texture3D, or if pResource has not been registered for use with CUDA, then cudaErrorInvalidHandle is returned.
For usage requirements of subResource parameters see cudaD3D10ResourceGetMappedPointer().
Parameters:
pWidth - Returned width of surface
pHeight - Returned height of surface
pDepth - Returned depth of surface
pResource - Registered resource to access
subResource - Subresource of pResource to access

cudaGraphicsSubResourceGetMappedArray

__CUDA_DEPRECATED cudaError_t cudaD3D10ResourceSetMapFlags (ID3D10Resource * pResource, unsigned int flags)

Deprecated
This function is deprecated as of CUDA 3.0.
Set usage flags for mapping the Direct3D resource pResource.
Changes to flags will take effect the next time pResource is mapped. The flags argument may be any of the following:
o cudaD3D10MapFlagsNone: Specifies no hints about how this resource will be used. It is therefore assumed that this resource will be read from and written to by CUDA kernels. This is the default value.
o cudaD3D10MapFlagsReadOnly: Specifies that CUDA kernels which access this resource will not write to this resource.
o cudaD3D10MapFlagsWriteDiscard: Specifies that CUDA kernels which access this resource will not read from this resource and will write over the entire contents of the resource, so none of the data previously stored in the resource will be preserved.
If pResource has not been registered for use with CUDA then cudaErrorInvalidHandle is returned. If pResource is presently mapped for access by CUDA then cudaErrorUnknown is returned.
Parameters:
pResource - Registered resource to set flags for
flags - Parameters for resource mapping
Returns:
cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidResourceHandle, cudaErrorUnknown,
Note:
Note that this function may also return error codes from previous, asynchronous launches.
