Abstract: Methods and apparatus for bi-directional control of computing unit frequency are disclosed. An example apparatus to control a frequency of a computing unit includes instructions, memory in the apparatus, and processor circuitry. The processor circuitry is to determine a performance hint from a first register, the performance hint corresponding to a requested performance of the computing unit for executing a thread associated with software, determine power and performance (PnP) statistics pertaining to the thread from a second register, control the frequency of the computing unit based on the performance hint and the PnP statistics, and provide a pressure of the computing unit to the software.
