General informations

The Linux kernel configuration item CONFIG_POWER_AVS:

• prompt: Adaptive Voltage Scaling class support
• type: bool

• defined in drivers/power/avs/Kconfig
• found in Linux kernels: 3.6–3.19, 4.0–4.20, 5.0–5.9

Help text

AVS is a power management technique which finely controls the operating voltage of a device in order to optimize (i.e. reduce) its power consumption. At a given operating point the voltage is adapted depending on static factors (chip manufacturing process) and dynamic factors (temperature depending performance). AVS is also called SmartReflex on OMAP devices.

Say Y here to enable Adaptive Voltage Scaling class support.
