Abstract
A mechanism for power management of processors using Pstates is provided. In a chiplet of a processor in a data processing system, a request is received to change a Pstate from a current Pstate to a requested Pstate. A determination is made as to whether the requested Pstate is less than or equal to a maximum Pstate. Responsive to the requested Pstate being less than or equal to the maximum Pstate, a frequency associated with the requested Pstate is computed thereby forming a computed frequency. An operating frequency of the chiplet is then adjusted to the computed frequency without involvement from a central power control entity.
