Hello, For the first time I have an AMD + Intel combo in my notebook. I use to have an Nvidia where I was able to use OpenCL.
Is there somebody having the same configuration and with OpenCL setup? I'm on GNU/Debian 9, so no fgrlx but using the AMDGPU driver. xserver-xorg-video-amdgpu I've also installed: amd-opencl-icd If I run clinfo I get: << Number of platforms: 1 Platform Profile: FULL_PROFILE Platform Version: OpenCL 2.0 AMD-APP (1800.11) Platform Name: AMD Accelerated Parallel Processing Platform Vendor: Advanced Micro Devices, Inc.
