* Updates enabling zone active fan controlMatthew Barth2017-08-161-2/+2
| | | | | | | | | | | | | | | A zone is actively controlling its fan speeds when all groups subscribed to allow active control are set to true. The zone keeps a list of these groups and their active allow state, if at anytime an action (or precondition) sets a group's active state to false, any dynamic set speed requests do not occur. Only requests to set the zone's fans to full speed is allowed. Related to this, the zone's target speed should only be updated when a requested speed is successfully set.

* Add factor parameter to inc/dec action functionsMatthew Barth2017-08-161-15/+23
| | | | | | | | | | | The factor parameter is used to correctly determine the increase or decrease speed delta based on sensor inputs that have a scale. To get the net speed delta change, the factor is applied to the difference in sensor value and the defined state at which a speed change should be requested.

* Handle any missing properties for actionsMatthew Barth2017-08-141-113/+166
| | | | | | | | | Update getting a property value from the zone's cache to throw an exception when not found. Handle these exceptions appropriately for each action where it gets each property value of a group.

* Support speed decrease eventsMatthew Barth2017-07-061-0/+52
| | | | | | | | | | | | | | | | | A net decrease speed action determines the net decrease delta from each group member's property value and requests a speed decrease of that delta from the current target speed. From all the requests for a speed decrease on a zone, only the lowest net decrease is used from all the groups subscribed to decrease a zone's speed. The new target speed is only decreased when no increase requests exist and the resulting target is above the zone's floor speed, otherwise the floor speed is set as the new target.

* Process speed increase requestsMatthew Barth2017-07-061-1/+2
| | | | | | | | | | | Speed increases are made providing a target speed delta. The increase is made when the delta is higher than the current increase that may be occurring. When no increase is currently happening, the increase delta requested is accepted. All resulting target increases will not go above a defined ceiling speed.

* Add zone net increase set speed actionMatthew Barth2017-07-061-0/+45
| | | | | | | | | The net increase speed action provides the ability to determine what the net delta the zone's fan speeds should be updated by from their current target speed. Change-Id: Ib463e5ed4836bebf906cea27ea5788d826ec9c38 Signed-off-by: Matthew Barth <msbarth@us.ibm.com>
* Enable setting/adjusting fan ceiling speedMatthew Barth2017-06-281-0/+109
| | | | | | | | | | | | | | | | | Set the default ceiling to be what's given as full speed and adjust the ceiling speed based on an average of a given set of sensor values. The ceiling is chosen from a given map's key transition values. The map consists of key, value pairs where each key is the sensor value transition point and the value is the ceiling speed for when that transition occurs. The previous key value is needed to determine the direction in which to chose the appropriate ceiling speed allowing a buffer zone between ceiling changes if defined to.

* Allow floor speed changes based on sensor valuesMatthew Barth2017-06-261-0/+50
| | | | | | | | | | Given a group of sensor values, the average of those sensor values will be used in selecting the floor speed for the zone. Each time the speed is set/updated, any speed requested lower than the current floor will be overwritten with the floor speed to not allow speeds below the floor.

| | | | | | | | The interface is needed on the properties stored to uniquely identify each property used in events. Change-Id: Ia062f25514d7ed04ef1023a02eecad4738711ffb Signed-off-by: Matthew Barth <msbarth@us.ibm.com>
* Add an active state for automatic fan controlMatthew Barth2017-05-311-1/+3
| | | | | | | | | | | | Each zone contains an active state that determines whether the automatic fan control algorithm is active and controlling the fan speeds dynamically or not. This will be used to determine if the fan speeds within the zone are set dynamically or rather held at another speed for a determined reason.
