psu-ng: Fix log error for missing PSU

Fixed missing PSU log error during power on. The issue was replicated
as follow:
1 - Chassis powered off
2 - Remove power cable from PSUx
3 - Remove PSUx from the carrier
4 - Power on chassis

Expect to see error log entry for missing PSUx. Fixed validateConfig to
only restart validationTimeout when there is a input fault and PSU
present or VINUVFault and PSU present.

Test:
  1 - System at standby
     a - Removed PSU0
     b - Reset BMC
     c - Power on chassis
     d - Verified error logged
  2 - System at standby
     a - Pull PSU cable
     b - Wait 10 seconds
     d - Remove PSU and power on the chassis
     d - Verified error logged
  3 - System at standby
     a - Remove power cord from PSU
     b - Chassis power on
     c - Verified an error is logged

Overview

This repository contains applications for configuring and monitoring devices that deliver power to the system.

  • cold-redundancy: Application that makes power supplies work in Cold Redundancy mode and rotates them at intervals.
  • phosphor-power-sequencer: Applications for configuring and monitoring power sequencer and related devices that support JSON-driven configuration.
  • phosphor-power-supply: Next generation power supply monitoring application.
  • phosphor-regulators: JSON-driven application that configures and monitors voltage regulators.
  • power-sequencer: A power sequencer monitoring application.
  • power-supply: Original power supply monitoring application.
  • tools/power-utils: Power supply utilities.

Build

To build all applications in this repository:

  meson setup 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:

  • Which applications to build and install.
  • Application-specific configuration data, such as power sequencer type.
  • Whether to build tests.

Power Supply Monitor and Util JSON config

Several applications in this repository require a PSU JSON config to run. The JSON config file provides information for:

  • Where to access the pmbus attributes
  • Which attribute file in pmbus maps to which property and interface in D-Bus
  • Which kernel device directory is used on which PSU

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:
    • Base: The base dir, e.g. /sys/bus/i2c/devices/3-0069/
    • Hwmon: The hwmon dir, e.g. /sys/bus/i2c/devices/3-0069/hwmon/hwmonX/
    • Debug: The pmbus debug dir, e.g. /sys/kernel/debug/pmbus/hwmonX/
    • DeviceDebug: The device debug dir, e.g. '/sys/kernel/debug/./`
    • HwmonDeviceDebug: The hwmon device debug dir, e.g. /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",
  }
