* Add increase & decrease timer values in secondsMatthew Barth2017-07-061-0/+11
| | | | | | | | | | | | | | | | | Support setting the increase delay time(in seconds) for each zone from the zone yaml file. Speed increases use a delay type timer where the amount of time given delays additional increase requests from happening until the fans within the zone reach the highest net increase in speeds. Support setting the decrease interval time(in seconds) for each zone from the zone yaml file. Since decreasing is done on an interval, a decrease interval time of zero disables the decrease interval timer causing no decreases in speed to occur. Speed decreases use an interval type timer to decrease the fan speeds within the zone when no speed increase requests exist on the given time interval.

* Set target speed according to floor speed changeMatthew Barth2017-07-061-10/+8
| | | | | | | | When the floor speed updates, a request to increase the target speed should be made when the target is now below the floor speed. Change-Id: Ib622bc717a952ef0c0703cbff40a4dc14b213416 Signed-off-by: Matthew Barth <msbarth@us.ibm.com>
* Timer for fan speed increasesMatthew Barth2017-07-061-0/+11
| | | | | | | | | | | | | A oneshot timer is started on each target speed increase where the amount of time configured is how long the fans within the zone are allowed to reach the new target speed before additional speed increase requests will be processed. Any speed increase request deltas that are above the current speed increase delta being processed as the new target speed will cause the timer to stop and the difference between the deltas are added onto the target speed.

* Timer to decrease fan speedsMatthew Barth2017-07-061-0/+14
| | | | | | | | | Create a repeating timer for decreasing fan speeds where the fan speeds in the zone are decreased when the timer expires and a decrease speed request exists with no increase request present or active.

* Support speed decrease eventsMatthew Barth2017-07-061-0/+23
| | | | | | | | | | | | | | | | | 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 Barth2017-07-061-0/+13
| | | | | | | | | | | 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/+15
| | | | | | | | | 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/+50
| | | | | | | | | | | | | | | | | 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/+15
| | | | | | | | | | 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.

* Add an active state for automatic fan controlMatthew Barth2017-05-311-0/+18
| | | | | | | | | | | | 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.
