2 PM Quality Of Service Interface
7 one of the parameters.
11 * The per-device PM QoS framework provides the API to manage the
12 per-device latency constraints and PM QoS flags.
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
23 aggregated target value is simply the min of the request values held in the list
29 From kernel space the use of this interface is simple:
35 Clients of PM QoS need to save the returned handle for future use in other
45 and call the notification tree if the target was changed as a result of
62 cleanup of a process, the interface requires the process to register its
80 2. PM QoS per-device latency and flags framework
83 For each device, there are three lists of PM QoS requests. Two of them are
84 maintained along with the aggregated targets of resume latency and active
86 Values are updated in response to changes of the request list.
88 The target values of resume latency and active state latency tolerance are
89 simply the minimum of the request values held in the parameter list elements.
90 The PM QoS flags aggregate value is a gather (bitwise OR) of all list elements'
97 From kernel mode the use of this interface is the following:
103 Clients of dev_pm_qos need to save the handle for future use in other
113 and call the notification trees if the target was changed as a result of
120 Check PM QoS flags of the given device against the given mask of flags.
121 The meaning of the return values is as follows:
131 or the list of requests is empty.
134 Add a PM QoS request for the first direct ancestor of the given device whose

146 PM QoS list of resume latency constraints and remove sysfs attribute

161 The per-device PM QoS framework has a per-device notification tree.
167 The callback is called when the aggregated value of the device constraints
