  • Method and apparatus for accurate measurement of platform power
    Patent number: 11422173
    Abstract: A Power Management Controller (PMC) which manages power states of a platform, informs a power accumulator device to start measuring the platform power during entry into the low power state (e.g., S0iX). The power accumulator device starts measuring the power until a stop message comes from the PMC. The PMC on detection of any wake event initiates a stop message to the power accumulator device. Once an operating system (OS) context is restored, software can read the measured data from the power accumulator device. The measured data is accessible to a host software using standard software application programming interface (API) and can be used to influence the power policies of the system.
