# phosphor-post-code-manager

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

To build phosphor-post-code-manager package , do the following steps:

```bash

meson 

ninja -C 

```

## Hosted Services

This repository ships `xyz.openbmc_project.State.Boot.PostCode.service` systemd

service along with its

[template version](https://github.com/openbmc/docs/blob/master/designs/multi-host-postcode.md)

and a tiny binary that exposes the necessary

[dbus interfaces & methods](https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/xyz/openbmc_project/State/Boot/PostCode.interface.yaml)

to extract the POST codes per boot cycle.

## Architecture

This repository is tightly coupled with

[phosphor-host-postd](https://github.com/openbmc/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](https://github.com/openbmc/phosphor-dbus-interfaces/blob/master/yaml/xyz/openbmc_project/State/Boot/Raw.interface.yaml)

property on `xyz.openbmc_project.State.Boot.Raw` interface & archive them per

boot on the filesystem, so that those can be exposed over

[redfish](https://github.com/openbmc/docs/blob/master/designs/redfish-postcodes.md)
