psu-ng: Add in ability to get presence via GPIO The device tree and entity-manager (D-Bus) properties have the power supply GPIO presence lines named, so we can use those GPIO line names to find the GPIO device to read for determining power supply presence. Some systems have the power supply presence lines in a gpio-keys section (notably IBM Rainier). To facilitate continued function while running with a device tree that has not removed those device tree entries, allow for a fallback to the old inventory D-Bus propertiesChanged or interfaceAdded matches for presence.

This repository contains applications for configuring and monitoring devices that deliver power to the system.
To build all applications in this repository:
meson build ninja -C build
To clean the repository and remove all build output:
rm -rf build
You can specify meson options to customize the build process. For example, you can specify:
Several applications in this repository require a PSU JSON config to run. The JSON config file provides information for:
There is an example psu.json to describe the necessary configurations.
inventoryPMBusAccessType
defines the pmbus access type, which tells the service which sysfs type to use to read the attributes. The possible values are:/sys/bus/i2c/devices/3-0069/
/sys/bus/i2c/devices/3-0069/hwmon/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/cffps1/
fruConfigs
defines the mapping between the attribute file and the FRU inventory interface and property. The configuration example below indicates that the service will read part_number
attribute file from a directory specified by the above pmbus access type, and assign to PartNumber
property in xyz.openbmc_project.Inventory.Decorator.Asset
interface."fruConfigs": [ { "propertyName": "PartNumber", "fileName": "part_number", "interface": "xyz.openbmc_project.Inventory.Decorator.Asset" } ]
psuDevices
defines the kernel device dir for each PSU in inventory. The configuration example below indicates that powersupply0
's device is located in /sys/bus/i2c/devices/3-0069
."psuDevices": { "/xyz/openbmc_project/inventory/system/chassis/motherboard/powersupply0" : "/sys/bus/i2c/devices/3-0069", }
