When dev-libs/amdgpu-pro-opencl is installed there shoult be opencl infrastructure working, eselect opencl list reports [1] ocl-icd * but when you run clinfo there is only segmentation fault and apps like xmr-stak doesn't work. But after mesa installation everything is working ok. Reproducible: Always Steps to Reproduce: 1. install clear gentoo from stage 3 with kernel and amdgpu driver for graphic card 2. install amdgpu-pro-opencl and clinfo 3. run clinfo Actual Results: segmentation fault Expected Results: Number of platforms 2 Platform Name AMD Accelerated Parallel Processing Platform Vendor Advanced Micro Devices, Inc.
