More Information
Summary:Standby power entry can be performed without latency tolerance information. The embodiments disclosed herein enable a power delivery system of a computing system to enter the requested low power state while ignoring any latency tolerance information throughout the platform. For example, an operating system (OS) can request a Forced Cx state (also known as a Forced C state), such as a Forced C10 state, allowing the system to ignore any latency tolerance information throughout the platform. This Forced Cx state can be used as a test mechanism to determine if a problematic device or integrated circuit is blocking entry into the low power state.
