Google patents system to manage power states in computing hardware

Google has filed a patent application for a method to manage how hardware components in a computing system turn on and off. The system tracks dependencies between parts, ensuring that one component only powers up if the parts it relies on are already active. It also records why specific components are powered up to help engineers diagnose performance issues.

Why it mattersThis improves the efficiency and reliability of computer systems by preventing hardware from turning on in the wrong order, which can save energy and reduce errors.

In the filing’s own words

Aspects of the disclosed technology provide methods and systems that put hardware in low power states (e.g., “off”). The technology provides support for sequencing of operations to properly power down and/or power up components (e.g., hardware) of a system. The technology provides support for management (e.g., ownership and/or administration) of policies associated with powering down and/or powering up components of a system. The technology provides support for attribution of why components of a system are powered up so that performance and/or functional demands are clear. Support is provided for diagnostics and/or observability of a system by making (e.g., exposing) information related to mechanization of power state transitions.

What exactly they claim (claim 1)

1. A method, comprising: receiving, by a power manager of a computing system, a request to transition a first power element to a requested power level, wherein: the first power element corresponds to a first component of the computing system, a second power element corresponds to a second component of the computing system, and the first power element has a power dependency on the second power element; and upon determination that the second power element is at a selected power level, causing, by the power manager based on the request and the power dependency, the first power element to transition to the requested power level.
