pseq: Remove deprecated files

Remove C++ and JSON files that are no longer needed by the
phosphor-power-sequencer application.

Over the past few months, several large enhancements have been
implemented in this application:
* New JSON file format that merges pin and rail elements, defines power
  on sequence order of rails, defines PMBus PAGEs, and provides an
  additional type of pgood fault checking based on output voltage.
* New pgood fault detection algorithm that is device independent, checks
  rails in power on sequence order, ignores PAGEs that are not voltage
  rails, and checks for faults using new output voltage method.
* New Device class hierarchy and Rail class that support automated
  testing.

Remove the old C++ classes that are no longer used.  Also remove the
configuration files that use the old JSON format.

Tested:
* Verified repository builds without errors
* Verified automated tests run without errors
* Verified application can successfully power the system on and off
  without errors

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",
  }
