Introduction +2. Data Structure Organization +3. DVFS APIs + +1. Introduction +=============== +DVFS is a technique that uses the optimal operating frequency and voltage to +allow a task to be performed in the required amount of time. +OMAP processors have voltage domains whose voltage can be scaled to +various levels depending on which the operating frequencies of certain +devices belonging to the domain will also need to be scaled. This voltage +frequency tuple is known as Operating Performance Point (OPP). A device +can have multiple OPP's. Also a voltage domain could be shared between +multiple devices. Also there could be dependencies between various +voltage domains for maintaining system performance like VDD<X> +should be at voltage v1 when VDD<Y> is at voltage v2. + +The design of this framework takes into account all the above mentioned points. +To summarize the basic design of DVFS framework:- + +1. Have device opp tables for each device whose operating frequency can be + scaled. This is easy now due to the existance of hwmod layer which + allow storing of device specific info. The device opp tables contain + the opp pairs (frequency voltage tuples), the voltage domain pointer + to which the device belongs to, the device specific set_rate and + get_rate API's which will do the actual scaling of the device frequency + and retrieve the current device frequency. +2. Introduce use counting on a per VDD basis. This is to take care multiple + requests to scale a VDD. The VDD will be scaled to the maximum of the + voltages requested. +3. Keep track of all scalable devices belonging to a particular voltage + domain the voltage layer. +4. Keep track of frequency requests for each of the device. This will enable + to scale individual devices to different frequency (even w/o scaling voltage + aka frequency throttling) +5. Generic dvfs API that can be called by anybody to scale a device opp. + This API takes the device pointer and frequency to which the device + needs to be scaled to. This API then internally finds out the voltage + domain to which the device belongs to and the voltage to which the voltage + domain needs to be put to for the device to be scaled to the new frequency + from he device opp table. Then this API will add requested frequency into + the corresponding target device frequency list and add voltage request to + the corresponding vdd. Subsequently it calls voltage scale function which + will find out the highest requested voltage for the given vdd and scales + the voltage to the required one. It also runs through the list of all + scalable devices belonging to this voltage domain and scale them to the + appropriate frequencies using the set_rate pointer in the device opp tables. +6.

Suppose Module M2 wants to run at OPP50 + frequency (say f2_opp50) instead of OPP100.
