OK, I guess. Although I still don't see why we need a user-visible option to control ARI independent of SR-IOV. When would a user want to enable CONFIG_PCI_ARI=y but not select CONFIG_PCI_IOV? (Also, by the way, why PCI_IOV instead of PCI_SR_IOV -- I assume in the future we may have PCI_MR_IOV, and matching the PCI terminology is probably easier for people to understand). - R. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
