1# IPZ VPD D-Bus Interfaces 2 3IPZ is a VPD (Vital Product Data) format used in IBM Power systems. 4The format consists of keywords that are stored as key-value 5pairs (Keyword name and its value). Keywords are grouped into records, 6usually with similar function grouped into a single record. 7 8The [OpenPower VPD] [1] format is quite similar to the IPZ format 9and describes the record-keyword structure. 10 11Also refer to the [VPD Collection design document] [2] that describes how the 12VPD collection application on the BMC will parse and publish the VPD data for 13IBM Power systems on D-Bus. 14 15The D-Bus interfaces defined here describe how IPZ VPD will be made available on 16D-Bus. Each YAML here represents a record in the IPZ VPD and keywords that 17belong to that record are represented as properties under that interface. 18The type of every property shall be a byte array. 19 20[1]: https://www-355.ibm.com/systems/power/openpower/posting.xhtml?postingId=1D060729AC96891885257E1B0053BC95 21[2]: https://github.com/openbmc/docs/blob/master/designs/vpd-collection.md 22
