Yeah, this is (or was) not a problem of Ubuntu nor it was a problem of Mesa.
In the end it was a problem of libclc (which is part of LLVM) not supporting newer Radeon hardware (I think anything newer than GCN4). Whatever, - this problem was resolved when the libclc was updated: https://github.com/llvm/llvm-project/pull/78884 Ergo, as of the end of January 2024 libclc includes support for Radeon hardware up to the RDNA2 generation. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/2029173 Title: fatal error: cannot open file '/usr/lib/clc/gfx1031-amdgcn-mesa- mesa3d.bc': No such file or directory Status in mesa package in Ubuntu: New Bug description: Programs using OpenCL report the following bug: fatal error: cannot open file '/usr/lib/clc/gfx1031-amdgcn-mesa-mesa3d.bc': No such file or directory This bug is encountered when trying to run github.com/ggerganov/llama.cpp build with CLBlast or just using clinfo.
