💖 CL_KHR_D3D11_SHARING 💖

okay bestie, welcome to the CL_KHR_D3D11_SHARING(3clc) page from the OpenCL Manual ✨ this is the one about making OpenCL and Direct3D 11 be friends. yes, it's giving crossover episode energy 🎀

🌸 NAME 🌸

cl_khr_d3d11_sharing — provide interoperability between OpenCL and Direct3D 11 🦋

#pragma OPENCL EXTENSION
cl_khr_d3d11_sharing : enable

like, that's the whole vibe. you turn it on with that pragma and suddenly your two GPU worlds are holding hands 🫶

✨ DESCRIPTION ✨

So the goal of this extension is to provide interoperability between OpenCL and Direct3D 11, and it's designed to function analogously to cl_khr_gl_sharing(3clc) as defined in sections 9.7 and 9.8 👑 no cap.

If an implementation supports this extension, then the string

"cl_khr_d3d11_sharing"

will be present in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string described in the table of allowed values for param_name for clGetDeviceInfo(3clc) 💅 so that's your vibe check right there — go look for that string and you'll know.

The interfaces for this extension are provided in the header file cl_d3d11.h 🌈

If the cl_khr_d3d11_sharing extension is supported, then the following functions are enabled:

The OpenCL functions enabled by the cl_khr_d3d11_sharing extension allow applications to use Direct3D 11 resources as OpenCL memory objects 💀 which is the whole point, and it allows efficient sharing of data between OpenCL and Direct3D 11 🔥

The OpenCL API may be used to execute kernels that read and/or write memory objects that are also Direct3D 11 resources. An OpenCL image object may be created from a Direct3D 11 texture resource. An OpenCL buffer object may be created from a Direct3D 11 buffer resource. 🎀

and here's the rule, bestie, do NOT skip it: OpenCL memory objects may be created from Direct3D 11 objects if and only if the OpenCL context has been created from a Direct3D 11 device. that's not a suggestion, that's the law 💅
