But this is a perfectly fine transitive select - PCI - yeah. But we can expect everything that selects VFIO_PCI_CORE to select PCI. Or a transitive select would be fine again - EVENTFD this is another classic transitive one that should just be selected instead of a user asking why it is not set - MMU: I suspect all of VFIO and thus the menuconfig really should depend on that So not really an issue here. VFIO_PCI_CORE really is underlying infrastructure a user should not care about.
