Implement PSU Event

Expose PSU Event AC Lost, Fan Fault, Failure, Predictive D-Bus interface.
Read alarm and max_alarm, min_alarm, crit_alarm, lcrit_alarm and
assert or deassert the related properties on PSU Event.

Tested By:
After run /usr/sbin/psusensor below D-Bus interface are exposed
/xyz/openbmc_project/State/Decorator/PSU1_OperationalStatus
/xyz/openbmc_project/State/Decorator/PSU2_OperationalStatus
After plugging out AC cable from PSU1, the functional property in
PSU1_OperationalStatus changes to "false" from "true".
After plugging in AC cable again, the property changes back to "true".

dbus-sensors

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.

key features

  • runtime re-configurable from d-bus (entity-manager or the like)

  • isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible

  • async single-threaded: uses sdbusplus/asio bindings

  • multiple data inputs: hwmon, d-bus, direct driver access
