For a +given circuit implementation the primary factors are: + +- Time the circuit spends in each 'power state' +- Temperature +- Operating voltage +- Process grade + +The time the circuit spends in each 'power state' for a given +evaluation period at first order means OFF or ON. However, +'retention' states can also be supported that reduce power during +inactive periods without loss of context. + +Note: The visibility of state entries to the OS can vary, according to +platform specifics, and this can then impact the accuracy of a model +based on OS state information alone. It might be possible in some +cases to extract more accurate information from system resources. + +The temperature, operating voltage and process 'grade' (slow to fast) +of the circuit are all significant factors in static leakage power +consumption. All of these have complex relationships to static power. + +Circuit implementation specific factors include the chosen silicon +process as well as the type, number and size of transistors in both +the logic gates and any RAM elements included. + +The static power consumption modelling must take into account the +power managed regions that are implemented. Taking the example of an +ARM processor cluster, the modelling would take into account whether +each CPU can be powered OFF separately or if only a single power +region is implemented for the complete cluster. + +In one view, there are others, a static power consumption model can +then start from a set of reference values for each power managed +region (e.g. CPU, Cluster/L2) in each state (e.g. ON, OFF) at an +arbitrary process grade, voltage and temperature point. These values +are then scaled for all of the following: the time in each state, the +process grade, the current temperature and the operating voltage. +However, since both implementation specific and complex relationships +dominate the estimate, the appropriate interface to the model from the +cpu cooling device is to provide a function callback that calculates +the static power in this platform. When registering the cpu cooling +device pass a function pointer that follows the `get_static_t` +prototype: + + int plat_get_static(cpumask_t *cpumask, int interval, + unsigned long voltage, u32 &power); + +`cpumask` is the cpumask of the cpus involved in the calculation. +`voltage` is the voltage at which they are operating. The function +should calculate the average static power for the last `interval` +milliseconds. It returns 0 on success, -E* on error. If it +succeeds, it should store the static power in `power`. Reading the +temperature of the cpus described by `cpumask` is left for +plat_get_static() to do as the platform knows best which thermal +sensor is closest to the cpu. + +If `plat_static_func` is NULL, static power is considered to be +negligible for this platform and only dynamic power is considered. + +The platform specific callback can then use any combination of tables +and/or equations to permute the estimated value. Process grade +information is not passed to the model since access to such data, from +on-chip measurement capability or manufacture time data, is platform +specific. + +Note: the significance of static power for CPUs in comparison to +dynamic power is highly dependent on implementation.

Conversely, `k_pu` is the +proportional term constant during temperature undershoot periods +(current temperature below "desired temperature" trip point). + +These controls are intended as the primary mechanism for configuring +the permitted thermal "ramp" of the system. For instance, a lower +`k_pu` value will provide a slower ramp, at the cost of capping +available capacity at a low temperature. On the other hand, a high +value of `k_pu` will result in the governor granting very high power +whilst temperature is low, and may lead to temperature overshooting. + +The default value for `k_pu` is: + + 2 * sustainable_power / (desired_temperature - switch_on_temp) + +This means that at `switch_on_temp` the output of the controller's +proportional term will be 2 * `sustainable_power`.

When the current temperature +is the desired one, then the proportional component is zero and +`P_max` = `sustainable_power`. That is, the system should operate in +thermal equilibrium under constant load. `sustainable_power` is only +an estimate, which is the reason for closed-loop control such as this. + +Expanding `k_pu` we get: + P_max = 2 * sustainable_power * (T_set - T) / (T_set - T_on) + + sustainable_power + +where + T_set is the desired temperature + T is the current temperature + T_on is the switch on temperature + +When the current temperature is the switch_on temperature, the above +formula becomes: + + P_max = 2 * sustainable_power * (T_set - T_on) / (T_set - T_on) + + sustainable_power = 2 * sustainable_power + sustainable_power = + 3 * sustainable_power + +Therefore, the proportional term alone linearly decreases power from +3 * `sustainable_power` to `sustainable_power` as the temperature +rises from the switch on temperature to the desired temperature. + +k_i and integral_cutoff +----------------------- + +`k_i` configures the PID loop's integral term constant. This term +allows the PID controller to compensate for long term drift and for +the quantized nature of the output control: cooling devices can't set +the exact power that the governor requests. When the temperature +error is below `integral_cutoff`, errors are accumulated in the +integral term. This term is then multiplied by `k_i` and the result +added to the output of the controller. Typically `k_i` is set low (1 +or 2) and `integral_cutoff` is 0. + +k_d +--- + +`k_d` configures the PID loop's derivative term constant.
