Now that the Vulkan API is released is there any indication regarding the schedule of releasing an OpenCL 2.1 driver with SPIR-V support?
We currently are evaluating market for OpenCL 2.1, what features of OpenCL 2.0 and 2.1 do you find atractive for Discrete GPU computing.
On SPIR-V how do you plan to use it. We do support in our current OpenCL driver SPIR 1.2.
I was hoping that OpenCL 2.1 driver was under development
SPIR-V seems to be the natural evolution of SPIR. Written from scratch (not dependent to LLVM IR). I guess that the usage of SPIR-V will induce less buggy and faster OpenCL kernel compilations. It will also push the OpenCL use in the industry as code obfuscation won't be required anymore.
..and the question still stands what OpenCL 2.1 features are you interested in using that inspired your query. Please read the first response as SPIR-V is already available.
As stated in the first response "SPIR 1.2" is supported. However, SPIR 1.2 is different from SPIR-V. If SPIR-V was supported it would practically mean that OpenCL 2.1 would also be supported.
This is not correct "If SPIR-V was supported it would practically mean that OpenCL 2.1 would also be supported." SPIR_V and OpenCL 2.1 are seperate projects at Khronos group. SPIR_V has dependency of OpenCL 2.1. Why do you need OpenCL 2.1 was the question.
If your looking to build a compiler we now have standard object format we been working on ROCm and have upstream our native code generator in the LLVM source tree.
Yes, SPIR-V and OCL 2.1 are separate projects, indeed. The most significant update brought by OCL 2.1 is SPIR-V support which would serve as a cross vendor intermediate language. However, after the recent announcement of planning a merging of OCL and Vulkan, the evolution of the former looks to be in a transitional state. So, I wouldn't expect broad vendor support of OpenCL 2.1 & 2.2. Not at least till the evolution of the specification is stabilized.
