Abstract: A method of adjusting core and un-core operating frequencies of two or more processors of a server includes determining core and un-core operating frequency variations versus power consumption limit variations of the two or more processors. The method also includes determining two or more first power consumption levels associated with the two or more processors. Each one of the two or more processors run at essentially a same target core operating frequency and at a same target un-core operating frequency at the respective first power consumption level of the processor. The method further includes adjusting the core and un-core operating frequencies of the two or more processors by setting a power consumption limit of each one of the two or more processors at the respective first power consumption level of the processor.

Abstract: Example implementations relate to a self-tune controller. For example, the self-tune controller may poll, via an out-of-band data stream, low-level operation information about a processor or a bus of a computing system under a present workload. At least some of the low-level operation information may be descriptive of a nature of traffic on the bus. The self-tune controller may program, via an out-of-band control signal, a setting of the computing system for the present workload based on the low-level operation information.

Abstract: Examples herein relate to an adjustment of a power limit of a processor. Examples disclose setting the power limit of the processor. The examples also obtaining a temperature difference between a die temperature of a core within the processor and a throttle temperature. In response to a determination that the temperature difference is at most equal to a temperature activation point, adjusting the power limit of the processor so that the adjust power limit is less than the set power limit.

Abstract: In one example in accordance with the present disclosure, a method may comprise collecting environment information for a processor, determining a maximum power level for the processor and setting a frequency level and a core-to-frequency ratio that maintains the maximum power for the processor. The frequency level and the core-to-frequency are respectively controlled by a programmable frequency register and a programmable core register. The method may comprise receiving a die temperature corresponding to the processor, determining that the die temperature exceeds a temperature corresponding to the processor and adjusting the maximum power to a level that maintains the temperature.
