This abstract first appeared for US patent application 20250093925 titled 'Power Management Interface for Multiple Software Requestors
Original Abstract Submitted
an apparatus includes a control circuit, configured to transition a plurality of power domains into selected performance states, and a set of state request registers. a state request register may include fields that are associated with respective power domains. the apparatus may further include circuit blocks configured to store respective state request values into respective state request registers. a given state request value may indicate a requested performance state for at least one of the power domains. in addition, a performance management circuit may be configured to select, using the associated fields in the registers, a particular performance state for at least one of the power domains. the performance management circuit may be further configured to determine a transition path to sequence to the selected performance state, and to cause the control circuit to transition to the selected performance state using the transition path.
