Hi, I am an Aparapi project developer that has been struggling for two years to get an RX 5700 properly running OpenCL applications.
First of all, as an end consumer, I would like to congratulate the open-source amdgpu driver for its stability and performance, as well as the team behind it! Unfortunately I cannot say the same for the closed source, proprietary drivers which have been a nightmare in terms of quality and stability and currently the only way to have OpenCL... which in reality is not the case, because it does not have any stability. The open-source driver has been superior in terms of OpenGL and Vulkan stability and performance, it just misses OpenCL to be complete. I am not expecting any reply on this, nor that it will make the Open-source OpenCL support for AMD graphics cards a reality... I just want to share this reality that I am experiencing for two years, with many amdgpu-pro driver versions tested and also the new deb based amdgpu-install drivers. None of them provided a working solution, neither legacy based, nor rocr based ones. The machine starts running a few OpenCL jobs, which after a few seconds lead to a black screen, followed by GPU reset and machine hanging. The same OpenCL jobs run fine on a GT 1030. There is also a big issue when running the RX 5700 as a secondary GPU, aside with the GT 1030 as the primary card, which causes the amdgpu driver to fail to load and renders the RX 5700 unusable. I just wanted to share my experience with this card and hope for a better future. Please consider Open-source OpenCL support in amdgpu/mesa. Best regards, Luís Mendes
