7 Two different PM QoS frameworks are available:
8 1. PM QoS classes for cpu_dma_latency, network_latency, network_throughput,
10 2. the per-device PM QoS framework provides the API to manage the per-device latency
11 constraints and PM QoS flags.

57 Returns the aggregated value for a given PM QoS class.
61 PM QoS class constraints list.
64 Adds a notification callback function to the PM QoS class. The callback is
65 called when the aggregated value for the PM QoS class is changed.
68 Removes the notification callback function for the PM QoS class.
91 2. PM QoS per-device latency and flags framework
93 For each device, there are three lists of PM QoS requests. Two of them are
95 state latency tolerance (in microseconds) and the third one is for PM QoS flags.
100 The PM QoS flags aggregate value is a gather (bitwise OR) of all list elements'
101 values.  Two device PM QoS flags are defined currently: PM_QOS_FLAG_NO_POWER_OFF
131 Check PM QoS flags of the given device against the given mask of flags.

166 The per-device PM QoS framework has 2 different and distinct notification trees:
