+# OpenBMC power supply monitoring application
Design document:
https://github.com/openbmc/docs/blob/master/designs/psu-monitoring.md
-# Compile Options
+## Compile Options
To enable reading VPD data via PMBus commands to IBM common form factor power
supplies (ibm-cffps), run meson with `-Dibm-vpd=true`.
-# D-Bus System Configuration
+## D-Bus System Configuration
Entity Manager provides information about the supported system configuration and
the power supply connectors (IBMCFFPSConnector).
The information is as follows:
-## Max Power Supplies
+### Max Power Supplies
Integer that indicates the maximum number of power supplies that should be
present. This is exposed via the `MaxCount` property.
-## I2C Bus
+### I2C Bus
The I2C bus(es) that the power supply is on will be represented by the `I2CBus`
property under the `xyz.openbmc_project.Configuration.IBMCFFPSConnector`
interface(s).
-## I2C Address
+### I2C Address
The I2C address(es) that the power supply is at will be represented by the
`I2CAddress` property under the IBMCFFPSConnector interface(s).
-## Name
+### Name
The `Name` property under the IBMCFFPSConnector interface(s) will be used to
create an inventory path for the power supply. This inventory path is used as
