* Create fan monitor init modeMatthew Barth2017-08-231-0/+1
| | | | | | | | | | | | | Allowing fan monitor to run in an init mode will set the fans to a functional state at each poweron for fans that were non-functional at poweroff. Then fan monitor can be started in monitor mode after the fans have ramped up to full speed and can begin being monitored for faults. This also allows for the removal of fan monitor doing a sd_notify prior to fan control starting. Change-Id: I634c9b4ec8bb30860dea54c8abd1cd6c56831d25 Signed-off-by: Matthew Barth <msbarth@us.ibm.com>

* Add dbus support to TachSensorMatt Spinler2017-05-111-0/+1
| | | | | | | | | | | | | | | TachSensor will match on properties changed signals for the Value and Target properties. When these occur, it will load in those properties and then tell the Fan class there was a change. Also, TachSensor will read in the Target property during construction so it will have a valid value to check against right away.

* Fan and TachSensor class introductionMatt Spinler2017-05-111-1/+3
| | | | | | | | | | | | | A Fan object has one or more TachSensor objects. The TachSensor class is used to keep track of the the actual and expected speeds. It only tracks expected speeds if the _hasTarget attribute is true. Future commits will add more functionality.

* Fan monitor dataMatt Spinler2017-05-111-0/+1
| | | | | | | | | | | This commit contains the data that will be used by the monitor code. The generated.cpp file will later be generated during the build by a python script. Change-Id: I4dc4552ae8e58cd27478416888dd3363e7c2bf3f Signed-off-by: Matt Spinler <spinler@us.ibm.com>
* phosphor-fan-monitor frameworkMatt Spinler2017-05-111-0/+17
This application will monitor the actual speeds of fans (via their sensors) and compare them to their expected speeds. If a fan is too slow for too long, it will have its Functional property in the inventory set to false. If it starts working again, the property will be set back to true. It will use configuration data to say which fans to check and which values to use for various timeout and deviation parameters.
