Adaptive Voltage Scaling (AVS) Class 0 is a procedure for lowering the voltage on certain device power rails. AVS Class 0 attempts to normalize the power consumption across all devices. The optimal voltage for each AVS supported rail of each device is determined after analysis in the factory, based on the strength of the device during manufacturing. This value is written in the device eFuse where it can be read through dedicated registers.
AVS can be enabled by system software after primary boot. Refer to Section 5.2.4.1, AVS Support, on how to enable AVS based on these registers.
