This guide helps you to develop energy-efficient products or applications that
        balance performance and power consumption.

It includes:

- Application processor subsystem (APSS) architecture
- CPU active power management through CPU frequency scaling mechanisms and its
                    tunables
- CPU idle management through CPU sleep power states

The features and power states explained here are for reference only.

Note: See [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-115/soc.html) that are supported on
                Qualcomm Linux.
