# Power management quality of service APIs

Source: [https://docs.qualcomm.com/doc/80-70014-30/topic/pmqos.html](https://docs.qualcomm.com/doc/80-70014-30/topic/pmqos.html)

The power management quality of service (PM QoS) API allows drivers to specify the
        latency requirement (in microseconds). If the wake-up latency of a CPU core Sleep state is
        longer than the specified QoS latency, then the CPU core does not enter the respective sleep
        state.
