| |
The pci_dma_configure() marks the iommu_group as containing only devices with kernel drivers that manage DMA. Avoid this default behavior for the pci_stub because it does not program any DMA itself. This allows the pci_stub still able to be used by the admin to block driver binding after applying the DMA ownership to vfio.
