Shift to boost asio library This commit shifts vpd manager from sdbusplus event loop to boost io_context event loop. The shift was done to have a more flexible way to perform async Dbus calls. For example read/write of vpd data can be performed asynchronously. It also removes dependency of Manager class on the interface class created as a part of Phosphor-Dbus-Interface repo. Test: - Introspect com.ibm.VPD.Manager /com/ibm/VPD/Manager to ensure that all the methods exposed under com.ibm.VPD.Manager interface matches to the ones documented under PDI repo. - Make DBus call to each of the exposed api to ensure that the funcation calls are working fine. -To ensure bios handler call back is working. Stop vpd-manager service. Stop pldm service. Start vpd-manager service Start pldm service. Should recieve callback. -To ensure gpio call back std::cout were added to callback function being trigerred on timer expiration and the same were verified in journal.

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.
