manager: Save and Restore BIOS Attributes This commit saves any updates made to BIOS attributes to VPD. It also restores the attributes from the VPD when we start VPD manager. Signed-off-by: Santosh Puranik <santosh.puranik@in.ibm.com> Change-Id: Idb28e2f89d21ccd89eb8e56490eb7f31397ff5f5
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.
