chassis-psu: New Functions for MultiChassis App
Implemented several functions for monitoring power supplies in
multi-chassis systems. Added a new main function, made minor
modification to the PowerSupply class, and added several functions to
the Chassis and ChassisManager classes.
The following is a summary of each object class new addition or modified
functions:
ChassisManager:
- initChassisPowerMonitoring(): Loops through all the chassis in the
system and initializes power monitoring process for each chassis's
PSUs.
Chassis:
- initPowerMonitoring(): Subscribe to D-Bus power change and initialize
power monitoring.
- supportedConfigurationInterfaceAdded(): Handle addition of supported
configuration and update missing PSUs.
- psuInterfaceAdded(): Handle addition of PSUs on D-Bus.
- validatePsuConfigAndInterfacesProcessed(): Validate the PSU
configuration and reset validation timer if power is on, supported
configs and have PSUs.
- analyzeBrownout(): Analyze PSUs for a brownout failure and log error.
- syncHistory(): Toggles the GPIO to sync power supply input history
readings.
- setInputVoltageRating(): Inform each PSUs to set its PSU input.
- createError(): Create OpenBMC error.
- hasRequiredPSUs(): TODO
- updateMissingPSUs(): Update PSU inventory.
- getSupportedConfiguration(): Retrieve supported configuration from
D-BUS and matches chassis ID with the current chassis id to update
chassis configuration.
- saveChassisName(): Save chassis short name in the class.
- powerStateChanged(): Handle for power state property changes.
- attemptToCreatePowerConfigGPIO(): Attempt to create GPIO
PowerSupply:
- PowerSupply(): Added additional class constructors. The constructors
have the same parameters as the original, except that the new
constructor include an extra parameter chassis short name.
- The PowerSupply class functions implementation remains the same as
the original, except for minor change in
PowerSupply::setupInputPowerPeakSensor(), where the sensorPath was
modified to include chassis name.
Test in simulation:
- Verified supported configuration added, where it polpulates
supported properties and updates PSUs changes.
- Validated some of the brownout functionality using fault injection.
- Validated the PowerSupply class sets the appropriate input voltage
for the target chassis PSUs.
- Verified that the chassis name is included in the PSU power input
peak sensors on D-bus.
