Package: ocl-icd-libopencl1 Version: 2.2.13-1 Severity: important Dear Maintainer,
Currently Debian does not have a working OpenCL library for a lot of AMD graphics drivers - mesa-opencl-icd does not work or often breaks; and ROCm is not yet packaged in Debian. The AMDGPU PRO OpenCL drivers work with the open source AMDGPU driver that is already part of Linux, but the official installation instructions are a bit convoluted. Here are simpler ones, please include them in the docs of this package: 1. Look for the latest linux drivers on the AMD website. For example at the time of writing this is: https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-45 2. Download the ones for Ubuntu, e.g.: https://drivers.amd.com/drivers/linux/amdgpu-pro-20.45-1164792-ubuntu-20.04.tar.xz 3. Unpack the tarball. This contains a ./amdgpu-pro-install script, however it will attempt to install the proprietary driver AMDGPU-PRO which is not necessary for us. (And it likely won't work, due to wanting a too-old version of linux than is in Debian Unstable.) Instead, we can install the unpacked Debian packages directly. You will need to install either: - opencl-orca-amdgpu-pro-icd, for older GPUs, or - opencl-rocr-amdgpu-pro, for newer ones. They can be installed both simultaneously in case you aren't sure which one works, or you need to switch GPUs constantly. Since you also need to install their dependencies, it's easiest to do this by adding: ~~~~ deb [ trusted=yes ] file:/path/where/you/extracted/ ./ ~~~~ to /etc/apt/sources.list.d/amdgpu-pro-local.list then running `apt-get update`. Then run `apt-get install opencl-orca-amdgpu-pro-icd opencl-rocr-amdgpu-pro`. 4. Finally run clinfo(1) with the right LD_LIBRARY_PATH to check that it worked. You should get something like: ~~~~ $ LD_LIBRARY_PATH=/opt/amdgpu-pro/lib/x86_64-linux-gnu/ clinfo -l Platform #0: AMD Accelerated Parallel Processing `-- Device #0: Ellesmere Platform #1: Clover `-- Device #0: Radeon RX 580 Series (POLARIS10, DRM 3.39.0, 5.9.0-4-amd64, LLVM 11.0.0) ~~~~ Clover being what is output by mesa-opencl-icd, unfortunately it doesn't work e.g. leela-zero runs into errors with it. 5. To avoid needing LD_LIBRARY_PATH, edit /etc/OpenCL/vendors/amdocl*.icd to instead contain the full path to the particular library.
