Package: src:linux Version: 4.20-1~exp1 Severity: normal The 4.20-1~exp1 configuration disabled CONFIG_HSA_AMD, necessary for using AMD's ROCm platform:
$ xzgrep CONFIG_HSA_AMD /usr/src/linux-config-4.20/config.amd64_none_amd64.xz # CONFIG_HSA_AMD is not set $ xzgrep CONFIG_HSA_AMD /usr/src/linux-config-4.19/config.amd64_none_amd64.xz CONFIG_HSA_AMD=m This was very likely unintentionally caused by 4.20 merging amdkfd into the amdgpu module (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=04d5e2765802241b54ee93d1e655123c39fa7385) which turned the HSA_AMD config option into a bool affecting the amdgpu module.
