Abstract: A mechanism for cache quota control is disclosed. A cache memory is configured to receive access requests from a plurality of agents, wherein a given request from a given agent of the plurality of agents specifies an identification value associated with the given agent of the plurality of agents. A cache controller is coupled to the cache memory, and is configured to store indications of current allocations of the cache memory to individual ones of the plurality of agents. The cache controller is further configured to track requests to the cache memory based on identification values specified in the requests and determine whether to update allocations of the cache memory to the individual ones of the plurality of agents based on the tracked requests.
