This phosphor-post-code-manager repository provides an infrastructure to persist the POST codes in BMC filesystem & it also owns the systemd services that are responsible for exposing the BIOS Post Codes to rest of the world via redfish.
To build phosphor-post-code-manager package , do the following steps:
meson <build directory> ninja -C <build directory>
This repository ships xyz.openbmc_project.State.Boot.PostCode.service systemd service along with its template version and a tiny binary that exposes the necessary dbus interfaces & methods to extract the POST codes per boot cycle.
This repository is tightly coupled with phosphor-host-postd OpenBMC repository which is responsible for emitting the dbus signals for every new POST Code.
phosphor-post-code-manager is architected to look for the property changed signals which are being emitted from the service that hosts Value property on xyz.openbmc_project.State.Boot.Raw interface & archive them per boot on the filesystem, so that those can be exposed over redfish
