cl_khr_d3d10_sharing

Provide interoperability between OpenCL and Direct3D 10.

#pragma OPENCL EXTENSION cl_khr_d3d10_sharing : enable

Description

The interfaces for this extension are provided in the header file cl_d3d10.h.

If the cl_khr_d3d10_sharing extension is supported, then the following functions are enabled:

The OpenCL functions enabled by the cl_khr_d3d10_sharing extension allow applications to use Direct3D 10 resources as OpenCL memory objects. This allows efficient sharing of data between OpenCL and Direct3D 10. The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 10 resources. An OpenCL image object may be created from a Direct3D 10 texture resource. An OpenCL buffer object may be created from a Direct3D 10 buffer resource. OpenCL memory objects may be created from Direct3D 10 objects if and only if the OpenCL context has been created from a Direct3D 10 device.

When the cl_khr_d3d10_sharing extension is enabled, this extends the list of allowable values in certain parameters of certain functions, as follows:

CL_CONTEXT_D3D10_DEVICE_KHR is accepted as a property name in the properties parameter of clCreateContext and clCreateContextFromType.
CL_CONTEXT_D3D10_PREFER_SHARED_RESOURCES_KHR is accepted as a value in the param_name parameter of clGetContextInfo.
CL_MEM_D3D10_RESOURCE_KHR is accepted as a value in the param_name parameter of clGetMemObjectInf.
CL_IMAGE_D3D10_SUBRESOURCE_KHR is accepted as a value in the param_name parameter of clGetImageInfo.
CL_COMMAND_ACQUIRE_D3D10_OBJECTS_KHR and CL_COMMAND_RELEASE_D3D10_OBJECTS_KHR are returned in the param_value parameter of clGetEventInfo when param_name is CL_EVENT_COMMAND_TYPE.
CL_INVALID_D3D10_DEVICE_KHR is returned by clCreateContext and clCreateContextFromType if the Direct3D 10 device specified for interoperability is not compatible with the devices against which the context is to be created.
CL_INVALID_D3D10_RESOURCE_KHR is returned by clCreateFromD3D10BufferKHR when resource is not a Direct3D 10 buffer object, and by clCreateFromD3D10Texture2DKHR and clCreateFromD3D10Texture3DKHR when resource is not a Direct3D 10 texture object.
CL_D3D10_RESOURCE_ALREADY_ACQUIRED_KHR is returned by clEnqueueAcquireD3D10ObjectsKHR when any of mem_objects are currently acquired by OpenCL.
CL_D3D10_RESOURCE_NOT_ACQUIRED_KHR is returned by clEnqueueReleaseD3D10ObjectsKHR when any of mem_objects are not currently acquired by OpenCL.
