Abstract: Described are mechanisms and methods for implementing highly configurable power delivery management policies. An apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may include a memory to store a first table having one or more first entries and to store a second table having one or more respectively corresponding second entries. The second circuitry may, upon the occurrence of an event, test a condition specified by an entry in the first table. The third circuitry may, upon the test of the condition having a positive result, evaluate a set of one or more parameters as specified by an entry in a second table corresponding with the entry in the first table. The fourth circuitry may initiate a power-management action based upon the evaluation of the set of one or more parameters.

Abstract: Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).

Abstract: When power is provided through a USB-C cable from a source device to a sink device, a sudden connection or disconnection of the cable between the two devices may cause a sudden power surge or power drop in at least one of those devices, leading to other problems. To avoid this sudden event from causing potential damage or disruption to one of the devices, in some embodiments a CC pin in the cable is used to announce the impending connection/disconnection, and the device may throttle back its power consumption before power is actually applied to or removed from the power pins.

Abstract: Methods, apparatus, and systems to dynamically schedule a workload to among compute blocks based on temperature are disclosed. An apparatus to schedule a workload to at least one of a plurality of compute blocks based on temperature includes a prediction engine to determine (i) a first predicted temperature of a first compute block of the plurality of compute blocks and (ii) a second predicted temperature of a second compute block of the plurality of compute blocks. The apparatus also includes a selector to select between the first compute block and the second compute block for assignment of the workload. The selection is based on which of the first and second predicted temperatures is lower. The apparatus further includes a workload scheduler to assign the workload to the selected one of the first or second compute blocks.

Abstract: In some examples, a power delivery system includes a primary power path to provide power to a computing system. The power delivery system also includes a bypass power path. A port manager is to disable the primary power path and to enable the bypass power path in response to a dead battery condition.
