Abstract
Embodiments of the inventive subject matter include setting minimum and maximum performance operating limits for each of a plurality of controllers. The operating limits are set in accordance with performance rules imposed on the system. In response to a request to change operation of a processing unit to a requested operational setting, it is determined whether the requested operational setting complies with the minimum and maximum performance operating limits. The minimum performance operating limit is sent to a performance controller if the requested operational setting does not comply with the minimum performance operating limit. The maximum performance operating limit is sent to a performance controller if the requested operational setting does not comply with the maximum performance operating limit. The requested operational setting is sent to a performance controller if the requested operational setting complies with the minimum and maximum performance operating limits.
