* ============
*
- *
* The algorithm used is the PID control algorithm, used the same way
* the published Darwin code does, using the same values that are
* present in the Darwin 8.10 snapshot property lists (note however
* controls with a tiny difference. The control-ids of hard-drive-fan
* and cpu-fan is swapped.
*
- *
* Target Correction :
*
* controls have a target correction calculated as :
* offset : -15650652
* slope : 1565065
*
- *
* Target rubber-banding :
*
* Some controls have a target correction which depends on another
*
* new_target = max (new_target, new_min >> 16)
*
- *
* # model_id : 2
* control : cpu-fan
* ref : optical-drive-fan
* offset : -32768000
* slope : 65536
*
- *
* In order to have the moste efficient correction with those
* dependencies, we must trigger HD loop before OD loop before CPU
* loop.
*
- *
* The various control loops found in Darwin config file are:
*
* HD Fan control loop.
* sensors : cpu-temp, cpu-power
* PID params : from SDB partition
*
- *
* CPU Slew control loop.
*
* control : cpufreq-clamp
* sensor : cpu-temp
