You are right. I sent a v2 covering radeon as well. Thanks, Michal
[PATCH v2] amdgpu, radeon: Add amdkfd softdep
Both amdgpu and radeon load amdkfd via symbol_request(). Add a softdep hint so that userspace knows that each of them needs amdkfd in the initrd.

It's a soft dependency, so it will be silently ignored. /sbin/modprobe --show-depends amdgpu will only list amdgpu.ko and its hard depedencies. Michal

The rest seem to be related but not dependent patches, so I'll leave it up to the respective maintainers to pick them up. Is that OK with you? Thanks, Michal

Please cc me on the proper > solution so I know when I can revert it again. It's not as trivial as it seemed, because there are at least three Makefiles that rely on the current behavior: init/Makefile drivers/misc/ibmasm/Makefile fs/logfs/Makefile While ibmasm and logfs can and probably should be fixed to work with modular 8250 and mtd, respectively, init/Makefile would need a workaround to only pick up do_mounts_rd.o and do_mounts_md.o if the respective block drivers are built-in. So we would be trading one hack for another. Michal

The likely reason why it is not doing it right now is that in an ideal world, modules are modules can be built out of tree against just the kernel and their static dependencies. In real world, we sometimes have features in modules that are enabled if other modules are enabled. I'll post a patch later. We also have lots of tests fo CONFIG_FOO || CONFIG_FOO_MODULE in built-in code, which is a similar case. Michal
