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