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.
