Techniques are disclosed relating to processor power control and interrupts. In one embodiment, an apparatus includes a processor configured to assert an indicator that the processor is suspending execution of instructions until the processor receives an interrupt. In this embodiment, the apparatus includes power circuitry configured to alter the power provided to the processor based on the indicator. In this embodiment, the apparatus includes throttling circuitry configured to, in response to receiving a request from the power circuitry to alter the power provided to the processor, block the request until the end of a particular time interval subsequent to receipt of the request or de-assertion of the indicator. In some embodiments, the particular time interval corresponds to latency between the processor receiving an interrupt and de-asserting the indicator.
