regulators: Improve gmock EXPECT_CALL() usage

Improve usage of gmock EXPECT_CALL() to specify the expected input
parameter values when useful.

The expected input parameter values to the mocked I2C interface are
important as they contain information like the register to read and the
number of bytes to read.

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",
  }
