4.29.1. Direct3D 11 Interoperability [DEPRECATED]
[Direct3D 11 Interoperability]
This section describes deprecated Direct3D 11 interoperability functionality.
Functions
- CUresult cuD3D11CtxCreate ( CUcontext* pCtx, CUdevice* pCudaDevice, unsigned int Flags, ID3D11Device* pD3DDevice )
- Create a CUDA context for interoperability with Direct3D 11.
- CUresult cuD3D11CtxCreateOnDevice ( CUcontext* pCtx, unsigned int flags, ID3D11Device* pD3DDevice, CUdevice cudaDevice )
- Create a CUDA context for interoperability with Direct3D 11.
- CUresult cuD3D11GetDirect3DDevice ( ID3D11Device** ppD3DDevice )
- Get the Direct3D 11 device against which the current CUDA context was created.
Functions
- CUresult cuD3D11CtxCreate ( CUcontext* pCtx, CUdevice* pCudaDevice, unsigned int Flags, ID3D11Device* pD3DDevice )
-
Create a CUDA context for interoperability with Direct3D 11.
Parameters
- pCtx
- - Returned newly created CUDA context
- pCudaDevice
- - Returned pointer to the device on which the context was created
- Flags
- - Context creation flags (see cuCtxCreate() for details)
- pD3DDevice
- - Direct3D device to create interoperability context with
Returns
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
Deprecated
This function is deprecated as of CUDA 5.0.
Description
This function is deprecated and should no longer be used. It is no longer necessary to associate a CUDA context with a D3D11 device in order to achieve maximum interoperability performance.
Note:Note that this function may also return error codes from previous, asynchronous launches.
See also:
- CUresult cuD3D11CtxCreateOnDevice ( CUcontext* pCtx, unsigned int flags, ID3D11Device* pD3DDevice, CUdevice cudaDevice )
-
Create a CUDA context for interoperability with Direct3D 11.
Parameters
- pCtx
- - Returned newly created CUDA context
- flags
- - Context creation flags (see cuCtxCreate() for details)
- pD3DDevice
- - Direct3D device to create interoperability context with
- cudaDevice
- - The CUDA device on which to create the context. This device must be among the devices returned when querying CU_D3D11_DEVICES_ALL from cuD3D11GetDevices.
Returns
CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_ERROR_INVALID_VALUE, CUDA_ERROR_OUT_OF_MEMORY, CUDA_ERROR_UNKNOWN
