H A Dpm_qos_interface.rst9 Two different PM QoS frameworks are available:
10 * CPU latency QoS.
11 * The per-device PM QoS framework provides the API to manage the
12 per-device latency constraints and PM QoS flags.
14 The latency unit used in the PM QoS framework is the microsecond (usec).
17 1. PM QoS framework
20 A global list of CPU latency QoS requests is maintained along with an aggregated
