14 The latency unit used in the PM QoS framework is the microsecond (usec).
20 A global list of CPU latency QoS requests is maintained along with an aggregated

49   Returns the aggregated value for the CPU latency QoS.
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.

91 maintained along with the aggregated targets of resume latency and active
92 state latency tolerance (in microseconds) and the third one is for PM QoS flags.
95 The target values of resume latency and active state latency tolerance are
147   Add a request to the device's PM QoS list of resume latency constraints and

190 If there is a latency tolerance control mechanism for a given device available
196 Whenever the effective latency tolerance changes for the device, its
199 latency tolerance requirements for the device is empty, the callback is expected
200 to switch the underlying hardware latency tolerance control mechanism to an

210 Then, user space can use that attribute to specify its latency tolerance
212 but do not let the hardware control latency tolerance" and writing "auto" to it
