Usage with conformance test #13

Hi I am trying to use this layer with https://github.com/KhronosGroup/OpenCL-CTS I am working on one of the latest Windows 10 version on Intel KBL platform (Intel(R) HD Graphics 630)

I am not sure which steps should be done in order. What I did I downloaded Microsoft.D3DMappingLayers_1.2011.2.0_x64__8wekyb3d8bbwe.Appx (Microsoft store do not allowed me install this) and manually installed this on my Windows. Next I uninstalled Intel Graphics driver I took my conformance binaries and run on this platform. I see that tests runs and reports such device/platform: Compute Device Name = Microsoft Basic Render Driver, Compute Device Vendor = Microsoft, Compute Device Version = OpenCL 1.2 D3D12 Implementation, CL C Version = OpenCL C 1.2 Is there any configuration that I will able to run application and see Compute Device Name = Intel(R) HD Graphics 630 ? Should the conformance tests be rebuild with OpenCLOn12 ? For any tips and clarification, thank you very much.

You can set environment variables for the conformance tests to change which platform and device they use. Set CL_PLATFORM_INDEX=1 to force the tests to skip Intel's ICD-provided platform and use the second one, which should be CLOn12.

You can also set CL_DEVICE_INDEX to change which D3D device is used by the test. Any hardware devices should be first, so leaving it at 0 should choose the Intel GPU.
