Provide sharing of data between OpenCL and selected adapter APIs (only DX9 at this time).
As currently proposed the interfaces for this extension
would be provided in header file cl_dx9_media_sharing.h
.
If the cl_khr_dx9_media_sharing
extension is supported, then
the following functions are enabled:
The OpenCL functions enabled by the cl_khr_dx9_media_sharing
extension allow applications to use media surfaces as OpenCL memory objects. This
allows efficient sharing of data between OpenCL and selected adapter APIs (only DX9
for now). If this extension is supported, an OpenCL image object can be created from
a media surface and the OpenCL API can be used to execute kernels that read and/or
write memory objects that are media surfaces. Note that OpenCL memory objects may
be created from the adapter media surface if and only if the OpenCL context has been
created from that adapter.
If this extension is supported by an implementation,
the string "cl_khr_dx9_media_sharing" will be present in the
CL_PLATFORM_EXTENSIONS
(see clGetPlatformInfo)
or CL_DEVICE_EXTENSIONS
(see clGetDeviceInfo).
As currently proposed the interfaces for this extension would be provided in
cl_dx9_media_sharing.h
