9 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
22 to the request list or elements of the list.  For CPU latency QoS, the

35   Clients of PM QoS need to save the returned handle for future use in other
36   PM QoS API functions.

53   CPU latency QoS list.
56   Adds a notification callback function to the CPU latency QoS. The callback is
57   called when the aggregated value for the CPU latency QoS is changed.
60   Removes the notification callback function from the CPU latency QoS.

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.
