ROCm user mode depends on userptr support. Without it, KFD is basically useless. Make sure HSA_AMD selects the same options as DRM_AMDGPU_USERPTR to avoid broken configurations where userptr gets enabled but its dependencies are disabled.

amd/amdgpu/Kconfig select HMM_MIRROR and MMU_NOTIFIER if DRM_AMDGPU_USERPTR is enabled,
I guess select DRM_AMDGPU_USERPTR here is enough, HMM_MIRROR and MMU_NOTIFIER is redundant.

help Enable this if you want to use HSA features on AMD GPU devices.
