Hi Narendra, Hi All, According to Documentation/ABI/testing/sysfs-bus-pci you are responsible for the index device attribute that is used by systemd to create network interface names. Now we would like to reuse this attribute for firmware provided PCI device index numbers on the s390 architecture which doesn't have SMBIOS/DMI nor ACPI. All code changes are within our architecture specific code but I'd like to get some Acks for this reuse. I've sent an RFC version of this patch on 15th of March with the subject: s390/pci: expose a PCI device's UID as its index but got no response. Would it be okay to re-use this attribute for essentially the same purpose but with index numbers provided by a different platform mechanism? I think this would be cleaner than further proliferation of /sys/bus/pci/devices/<dev>/xyz_index attributes and allows re-use of the existing userspace infrastructure.
