Yes, that's OK for the cases I've seen too. All the NTB devices I've seen are PCI_CLASS_BRIDGE_OTHER with type 0 headers, so this patch would not break anything. And I think the idea of allowing DMAR bridge scope for all devices with PCI class bridge is logical - BIOS writers probably are going by PCI class rather than header type when assigning scope. - R. _______________________________________________ iommu mailing list [email protected] https://lists.linuxfoundation.org/mailman/listinfo/iommu
