## Abstract

A processor in a device is configured to access a power policy for the device, where the power policy indicates a relationship between power consumption by the device and another performance variable of the device. The processor is also configured to produce an operating point for the device based at least in part on the power policy. The processor is also configured to provide information regarding the operating point to a management entity that manages the device.

### Claim 6

A method, comprising:
creating a power policy for a first device, wherein the power policy for the first device includes a power policy parameter based on a relationship between power consumption by the first device and another performance variable of the first device, and wherein the another performance variable includes a response time of the first device or a throughput of the first device;
generating an event at the first device, wherein the event indicates that the power consumption or the another performance variable has reached a predetermined threshold;
transmitting a notification of the event to a management entity that manages the first device, the management entity being external to the first device;
receiving a query regarding the event from the management entity, wherein the query is provided to the first device and to a second device;
determining responses to the query at the first device and at the second device, wherein the responses are based at least in part on the relationship between the power consumption and the another performance variable, and wherein the responses include a first projection of the power consumption at a first time based on applying the power policy parameter, a second projection of the power consumption at a second time after the first time based on applying the power policy parameter, a first projection of the another performance variable at the first time based on applying the power policy parameter, and a second projection of the another performance variable at the second time;
providing the responses to the query; and
implementing a second power policy for the first device based at least in part on the event, including managing a component of the first device and an activity of the first device to affect the power consumption.

### Claim 7 (depends on 6)
