Add validate-regulators-config.py validation tool.

validate-regulators-config.py is a tool that validates configuration
files for the phosphor-regulators application. See
phosphor-regulators/docs/config_file/README.md for the
command to use the tool.

Code for detecting and analyzing power faults on Witherspoon.

To Build

To build this package, do the following steps:

    1. meson build
    2. ninja -C build

To clean the repository again run `rm -rf build`.

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",
  }
