Can we reuse e.g virtio_pci_modern_probe() (or helpers in virtio_pci_modern.c) to do the probing? > > Signed-off-by: Zhu Lingshan <lingshan.zhu at intel.com> > --- >

If user did not configure any vdpa drivers, neither vhost nor virtio vdpa are going to be useful. So there's no point in prompting for these and selecting vdpa core automatically. Simplify configuration by making virtio and vhost vdpa drivers depend on vdpa menu entry. Once done, we no longer need a separate menu entry, so also get rid of this. While at it, fix up the IFC entry: VDPA->vDPA
