Mechanism to provide workload and configuration-aware deterministic performance for microprocessors

A method, comprising:

• receiving at a processor configuration information that describes a configuration setting and/or expected usage case for said processor;
• said processor determining a read address from said configuration setting and/or expected usage case;
• said processor applying said read address to a non volatile storage resource on said processor, said non volatile storage resource storing information to establish an appropriate frequency of said processor as a function of various configuration settings and/or expected usage cases of said processor;
• and,
• said processor reading an appropriate item of information from said information for said configuration setting and/or expected usage case from said non volatile storage resource and providing said information externally from said processor.

A tangible computer readable medium storing program code that when processed by a computer causes said computer to perform a method, said method comprising:

• recognizing a configuration change and/or expected usage change to a processor;
• receiving new information to establish a new operating frequency of said processor for a particular performance state of said processor in view of said configuration change and/or expected usage change;
• and,
• causing said new operating frequency to be applied to said processor while said processor is in said particular performance state.
