vpd-tool:Option to fixSystemVPD keywords This commit has an added option in vpd-tool that fixes system VPD restorable keywords in an interactive way. This option is required in a field usecase. In the field when there is a fault in BMC and BMC gets replaced, the replaced BMC VPD will now have all blank data. Now the Product engineer can use vpd-tool fixSystemVPD option to update the BMC critical keywords by chosing the corresponding keyword data from system backplane. Similarly when the system backplane is replaced, using the option, the PEs' can copy the keyword data from BMC. When both system backplane and BMC are replaced, the PEs' will have option to update new value on both. This interactive tool option eases keyword data updation and avoids manual updation for each and every mismatching critical keyword.

This repository hosts code for OpenPower and IBM IPZ format VPD parsers. Both OpenPower VPD and IPZ VPD formats are structured binaries that consist of records and keywords. A record is a collection of multiple keywords. More information about the format can be found here.
The repository consists of two distinct applications, which are:
This is a build-time YAML driven application that parses the OpenPower VPD format and uses the YAML configuration (see extra-properties-example.yaml and writefru.yaml) to determine:
The application instance must be passed in the file path to the VPD (this can, for example, be a sysfs path exposed by the EEPROM device driver) and also the D-Bus object path(s) that EEPROM data needs to be published under.
This parser is can be built by passing in the --enable-ibm-parser configure option. This parser differs from the OpenPower VPD parser in the following ways:
# and are > 255 bytes in length).Making the application runtime JSON driven allows us to support multiple systems (with different FRU configurations) to be supported in a single code image as well as making the application more flexible for future improvements.
