Priority based throttling for power/performance quality of service

An apparatus comprising:

• a processor including:
• a first processing element adapted to execute a first software entity;
• a second processing element adapted to execute a second software entity;
• storage adapted to hold a first priority level associated with the first software entity and a second priority level associated with the second software entity, wherein the first priority level is higher than the second priority level;
• monitor logic adapted to monitor utilization of a shared resource by the first processing element and the second processing element;
• and
• a priority aware manager adapted to set a first operating point of the first processing element to a higher operating point than a second operating point of the second operating element based on the first priority level being higher than the second priority level and the utilization of the shared resource by the first and second processing elements in relation to the first and second priority levels, wherein the first operating point of the first processing element includes access to a first number of ways of a cache memory and the second operating point of the second processing element includes access to a second number of ways of the cache memory, the first number of ways being greater than the second number of ways.

An apparatus comprising:

• a processor including:
• priority usage logic adapted to indicate utilization of a resource associated with a first priority level and utilization of the resource associated with a second priority level, wherein the first priority level is lower than the second priority level;
• and
• priority aware management logic coupled to the priority usage logic adapted to reduce an-a first operating point of a first processing element, which is to be associated with a first software entity of the first priority level executed by a first processing element, in response to the utilization of the resource associated with the first priority level being above a predefined utilization amount, wherein the first operating point of the first processing element includes a first number of credits to access a memory and a second operating point of a second processing element that executes a second software entity associated with a second priority level includes a second number of credits to access the memory, the first number of credits being greater than the second number of credits.
