POWER CONTROL FOR INFORMATION HANDLING SYSTEM HAVING SHARED RESOURCES
First Claim
Patent Images
1. A method comprising:
- detecting a first event at a first processing system of an information handling system having a plurality of system resources;
in response to detecting the first event at the first processing system, determining a first power mode for a first system resource based on the first event, first state information indicative of a state of the first processing system, and second state information indicative of a state of a second processing system of the information handling system, wherein the first power mode is one of an active power mode and a reduced power mode; and
setting an operating power mode of the first system resource to the first power mode.

Abstract
An information handling system includes at least two processing systems that share system resources. In response to detecting a designated event, a power control module of the information handling system can select one of a plurality of available power profiles. The power profile can be selected based on the event and state information indicative of a state of the processing systems. Based on the selected profile, the power control module can set an operational power mode of one or more of the shared system resources.

11. A processor readable medium tangibly embodying a program of instructions to manipulate a processor, the program of instructions comprising instructions to:
-
detect a first event at an information handling system; in response to the first event; select a first power profile from a plurality of available power profiles on the first event; and set an operational power mode of a first plurality of system resources of the information handling system based on the first power profile, the first plurality of system resources comprising resources that are shared between a first processing system of the information handling system and a second processing system of the information handling system. - View Dependent Claims (12, 13, 14, 15, 16)

17. An information handling system, comprising:
-
a first processing system; a second processing system; a first plurality of system resources comprising shared resources between the first processing system and the second processing system; an event detection module configured to detect an event at the information handling system and communicate a first indication in response to the event; and a power control module configured to, in response to the first indication, select a first power profile from a plurality of available power profiles based on an the first event and configured to set a power mode of each of the first plurality of system resources based on the first power profile. - View Dependent Claims (18, 19, 20)
