Abstract:
In an embodiment, a processor includes a first core and a power management agent (PMA), coupled to the first core, to include a static table that stores a list of operations, and a plurality of columns each to specify a corresponding flow that includes a corresponding subset of the operations. Execution of each flow is associated with a corresponding state of the first core. The PMA includes a control register (CR) that includes a plurality of storage elements to receive one of a first value and a second value. The processor includes execution logic, responsive to a command to place the first core into a first state, to execute an operation of a first flow when a corresponding storage element stores the first value and to refrain from execution of an operation of the first flow when the corresponding element stores the second value. Other embodiments are described and claimed.
