Abstract: Various aspects relate to methods and computing systems that implement closed-loop workload hint protocol bridging an operating system (OS) power manager and a power management controller (PMC). The OS power manager generates a structured workload hint encoding a plurality of workload-context parameters characterizing predicted idle behavior and transmits the hint to the PMC via a platform interface. The PMC dynamically adjusts a break-even threshold for selecting among a plurality of idle states based on a multi-factor function of the hint-derived parameters. Effectiveness telemetry is reported from the PMC back to the OS via a telemetry interface, enabling the OS to calibrate subsequent hint generation. A dual-layer prediction cross-validation architecture enables both the OS and the PMC to independently validate the hint using complementary information sources, with feedback-driven reclassification of activity classes for continuous enhancement.

Abstract: Methods and systems for automatic or semi-automatic configuration of an array of multiple monitors are disclosed. In various embodiments, a computer system attached to a plurality of monitors causes each of the monitors to display a unique identifier. A picture is then captured of the physical layout of the plurality of monitors, which is analyzed to detect monitor edges and extract the unique identifier displayed on each monitor. The detected edges and extracted identifiers are then used to determine the physical layout of the plurality of monitors, which is then provided back to the computer system for appropriate configuration. The unique identifier may also convey monitor information such as resolution, to allow the operating system to set various parameters such as font scaling.
