Parse I2C bus and address out of JSON config file The I2C bus and address need to be passed down to the PowerSupply constructor, so get those out of the JSON configuration file now. Change I2C address format in JSON to be a string, without the hexadecimal format since it needs to be appended to a string, allowing to skip conversion from string to number and then from number back to string.

Code for detecting and analyzing power faults on Witherspoon.
To build this package, do the following steps: 1. meson build 2. ninja -C build To clean the repository again run `rm -rf build`.
Several applications in this repository require a PSU JSON config to run. The JSON config file provides information for:
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:/sys/bus/i2c/devices/3-0069/
/sys/bus/i2c/devices/3-0069/hwmon/hwmonX/
/sys/kernel/debug/pmbus/hwmonX/
/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", }
