power-utils: Initially add isReadyToUpdate Initially add isReadyToUpdate() that checks the pre-condition for PSU update. For now it only checks the power state and return false if power is on. When it is not ready to update, there is no need to unbind/bind the driver, so move the unbind/bind calls into doUpdate() from ctor/dtor. Tested: Verify it returns and logs "PSU not ready to update" when power is on, and continues the update when power is off.

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", }
