The driver build should work without IOMMUv2. In amdkfd/Makefile, we
have this condition:
ifneq ($(CONFIG_AMD_IOMMU_V2),)
AMDKFD_FILES += $(AMDKFD_PATH)/kfd_iommu.o
endif
In amdkfd/kfd_iommu.h we define inline stubs of the functions that are
causing your link-failures if IOMMU_V2 is not enabled:
From: Arnd Bergmann
Using 'imply AMD_IOMMU_V2' does not guarantee that the driver can link
against the exported functions. If the GPU driver is built-in but the
IOMMU driver is a loadable module, the kfd_iommu.c file is indeed
built but does not work:
x86_64-linux-ld: drivers/gpu/drm/amd/amdkfd/
