2 PM Quality Of Service Interface
9 Two different PM QoS frameworks are available:
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
35 Clients of PM QoS need to save the returned handle for future use in other
36 PM QoS API functions.
68 Only processes can register a PM QoS request. To provide for automatic
72 To register the default PM QoS target for the CPU latency QoS, the process must
87 2. PM QoS per-device latency and flags framework
90 For each device, there are three lists of PM QoS requests. Two of them are
92 state latency tolerance (in microseconds) and the third one is for PM QoS flags.
97 The PM QoS flags aggregate value is a gather (bitwise OR) of all list elements'
98 values. One device PM QoS flag is defined currently: PM_QOS_FLAG_NO_POWER_OFF.
127 Check PM QoS flags of the given device against the given mask of flags.
137 The device's PM QoS structure has not been initialized

168 The per-device PM QoS framework has a per-device notification tree.
