Abstract
A system for controlling power to multiple processing cores operating in separate domains in an information handling system (IHS) is provided. The system includes a power regulator that is programmable to output voltage depending on a processor domain and a corresponding performance state. In some instances, one processor may be an integrated graphics processing unit, and another processor may be a discrete graphics processing unit.
Claims21
An information handling system (IHS) comprising:
- a first processor operable in a first domain;
- a second processor operable in a second domain;
- system memory in communication with the first processor and the second processor;
- and
- a power regulator in communication with the first processor and the second processor, wherein the power regulator provides power to the first processor in the first domain and the second processor in the second domain.
An information handling system (IHS) comprising:
- a host complex, wherein the host complex comprises an integrated graphics processing unit (iGPU) operable in a first domain;
- a discrete graphics processing unit (dGPU) operable in a second domain;
- system memory in communication with the host complex;
- and
- a power regulator in communication with the host complex, the iGPU, and the dGPU, wherein the power regulator is operable to provide power to the iGPU in the first domain and the dGPU in the second domain.
A method for managing power to multiple processors in an information handling system (IHS), the method comprising:
- determining a domain and a performance state between a first processor and a second processor;
- reporting a parameter associated with the domain and the performance state to a power regulator of the IHS;
- and
- outputting a voltage corresponding to the parameter to either the first processor or the second processor.
