摘要： A mechanism is provided for directed resource folding for power management. The mechanism receives a set of static platform characteristics and a set of dynamic platform characteristics for a set of resources associated with the data processing system thereby forming characteristic information. The mechanism determines whether one or more conditions have been met for each resource in the set of resources using the characteristic information. Responsive to the one or more conditions being met, the mechanism performs a resource optimization to determine at least one of a first subset of resources in the set of resources to keep active and a second subset of resources in the set of resources to dynamically fold. Based on the resource optimization, the mechanism performs either a virtual resource optimization to optimally schedule the first subset of resources or a physical resource optimization to dynamically fold the second subset of resources.

摘要： An apparatus for providing system memory usage throttling within a data processing system having multiple chiplets is disclosed. The apparatus includes a system memory, a memory access collection module, a memory credit accounting module and a memory throttle counter. The memory access collection module receives a first set of signals from a first cache memory within a chiplet and a second set of signals from a second cache memory within the chiplet. The memory credit accounting module tracks the usage of the system memory on a per user virtual partition basis according to the results of cache accesses extracted from the first and second set of signals from the first and second cache memories within the chiplet. The memory throttle counter for provides a throttle control signal to prevent any access to the system memory when the system memory usage has exceeded a predetermined value.

摘要： Managing operations associated with one or more voltage changes and one or more frequency changes. A voltage change request and a frequency change request are associated with dynamic voltage and frequency scaling (DVFS) operations. The DVFS operations are transmitted by the processors to be executed by one or more direct current assemblies. A sequence associated with the one or more voltage changes and a sequence associated with the one or more frequency changes are detected by the system. The sequences are dynamically modified to enable insertion of an additional voltage change, whereby the additional voltage change indicates completion of one or more previous voltage change requests. Completion of the voltage change request enables one or more subsequent voltage change requests to be processed. When a voltage change request is not successfully completed one or more future voltage changes are suspended.

摘要： A mechanism is provided for unified management of power, performance, and thermals in computer systems. This mechanism incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The mechanism employs an infrastructure for real-time measurements feedback, an infrastructure for regulating system activity, component operating levels, and environmental control, a dedicated control structure for guaranteed response/preemptive action, and interaction and integration components. The mechanism provides interfaces for user-level interaction. The mechanism also employs methods to address power/thermal concerns at multiple timescales. In addition, the mechanism improves efficiency by adopting an integrated approach, rather than treating different aspects of the power/thermal problem as individual issues to be addressed in a piecemeal fashion.

摘要： Semiconductor device circuits and methods are provided for adjusting core processor performance and energy-efficiency based on usage metrics. Metric detection, performance state selection, and adjustment are done in digital logic hardware without intervening input from system software or firmware, thus greatly speeding the processor performance adjustment. Mapping usage and state information to desired processor power-performance states is also provided in circuitry rather than firmware or power control software. The mapping values may be programmable software or firmware, but detection, selection, and adjustment occur automatically in hardware without intervening input from firmware or software.

摘要： A mechanism is provided for using a power proxy unit combined with on-chip actuators to meet a defined power target value identifying a target power consumption of a component of a data processing system. A power manager in the data processing system identifies a proxy power threshold value, for the defined power target value, identifying a maximum power usage for the component, and a power usage estimate value identifying a current power usage estimate for the component. The power manager sends a set of signals to one or more on-chip actuators in the power proxy unit associated with the component in response to the power usage estimate value being greater than the power proxy threshold value. The one or more on-chip actuators adjusts a set of operational parameters associated with the component in order to meet the defined power target value.

摘要： Disclosed are systems, methods, and computer program products for managing power states in processors of a data processing system. In one embodiment, the invention is directed to a data processing system having dynamically configurable power-performance states (“pstates”). The data processing system includes a processor configured to operate at multiple states of frequency and voltage. The data processing system also has a power manager module configured to monitor operation of the data processing system. The data processing system further includes a pstates table having a plurality of pstate definitions, wherein each pstate definition includes a voltage value, a frequency value, and at least one unique pointer that indicates a transition from a given pstate to a different pstate. The voltage value, frequency value, and unique pointer of a given pstate definition are configurable, during operation of the data processing system, by the power manager module in response to changes in the operating parameters of the data processing system.

The mechanism receives a set of static platform characteristics and a set of dynamic platform characteristics for a set of resources associated with the data processing system thereby forming characteristic information. The mechanism determines whether one or more conditions have been met for each resource in the set of resources using the characteristic information. Responsive to the one or more conditions being met, the mechanism performs a resource optimization to determine at least one of a first subset of resources in the set of resources to keep active and a second subset of resources in the set of resources to dynamically fold.
