Currently the kconfig logic for VFIO_IOMMU_SPAPR_TCE and VFIO_SPAPR_EEH is broken when SPAPR_TCE_IOMMU=n. Leading to: warning: (VFIO) selects VFIO_IOMMU_SPAPR_TCE which has unmet direct dependencies (VFIO && SPAPR_TCE_IOMMU) warning: (VFIO) selects VFIO_IOMMU_SPAPR_TCE which has unmet direct dependencies (VFIO && SPAPR_TCE_IOMMU) drivers/vfio/vfio_iommu_spapr_tce.c:113:8: error: implicit declaration of function 'mm_iommu_find' This stems from the fact that VFIO selects VFIO_IOMMU_SPAPR_TCE, and although it has an if clause, the condition is not correct. We could fix it by doing select VFIO_IOMMU_SPAPR_TCE if SPAPR_TCE_IOMMU, but the cleaner fix is to drop the selects and tie VFIO_IOMMU_SPAPR_TCE to the value of VFIO, and express the dependencies in only once place. Do the same for VFIO_SPAPR_EEH. The end result is that the values of VFIO_IOMMU_SPAPR_TCE and VFIO_SPAPR_EEH follow the value of VFIO, except when SPAPR_TCE_IOMMU=n and/or EEH=n. Which is exactly what we want to happen. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: Alex Williamson <alex.williamson@redhat.com> |
