摘要： Computing system voltage control methods include receiving an indication of a first performance state. The first performance state is associated with a first voltage and applies to at least one computing system component. The indication of the first performance state is received by a first computing system component from a second computing system component. An indication of a second performance state is received, wherein the second performance state is associated with a second voltage that is not equal to the first voltage. It is determined whether the second performance state is within a range defined by a minimum performance state and a maximum performance state. Responsive to determining that the second performance state is within the range defined by the minimum performance state and the maximum performance state, the voltage of the at least one computing system component is set equal to the voltage associated with the second performance state.

摘要： 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.
