clang-format: re-format for clang-19

clang-format-19 isn't compatible with the clang-format-18 output, so we
need to reformat the code with the latest version.  A few parameters
in clang-tidy have been deprecated, so adjust the style file
accordingly.

See Ie2f6eb3b043f2d655c9df806815afd7971fd0947 for updated style.
See I88192b41ab7a95599a90915013579608af7bc56f for clang-19 enablement.

phosphor-power

Overview

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

Actively-maintained applications:

  • cold-redundancy: Application that makes power supplies work in Cold Redundancy mode and rotates them at intervals.
  • phosphor-power-sequencer: JSON-driven application that powers the chassis on/off and monitors the power sequencer device.
  • phosphor-power-supply: Next generation power supply monitoring application.
  • phosphor-regulators: JSON-driven application that configures and monitors voltage regulators.
  • tools/power-utils: Power supply utilities.

Legacy applications:

  • power-sequencer: Original power sequencer monitoring application.
  • power-supply: Original power supply monitoring application.

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/<driver>.<instance>/
    • 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",
  }
