Now that ROCm has been updated in #55948, I tested again if I needed this kernel config change. Indeed, without CONFIG_HSA_AMD I do not get OpenCL with ROCm (darktable-cltest fails, as does rocminfo). I again set this configuration option and it works.

Any obstacles to (re)enabling this configuration option?

Thanks!
John
