Methods and systems to dynamically manage performance states in a data processing system

A data processing system, comprising:

• a plurality of components;
• one or more buses coupled to the plurality of components,
• a dynamic performance state manager unit coupled to the components, the dynamic performance state manager unit being configured to receive an information about a first plurality of current states of components of the system;
• the dynamic performance state manager unit being configured to determine a second plurality of required system performance states for the components;
• and the dynamic performance state manager unit being configured to determine a current system performance state based on the first plurality and the second plurality.

A machine readable medium containing executable program instructions which cause a data processing system to perform operations comprising:

• receiving an information about a first plurality of current states of components of the system;
• determining a second plurality of required system performance states for the components;
• and
• determining a current system performance state based on the first plurality and the second plurality.

A data processing system comprising:

• means for receiving an information about a first plurality of current states of components of the system;
• means for determining a second plurality of required system performance states for the components;
• and
• means for determining a current system performance state based on the first plurality and the second plurality.
