org.freedesktop.DeviceKit.Power.QoS is a DBus interface implimented
|
||||||
|
by DeviceKit-power.
|
||||||
|
It allows applications to request latencies, for example a couple of seconds
|
||||||
|
for an IM application, or a few hundred microseconds for a multiplayer game.

Why don't applications use the PMQoS interface directly?
|
||||||
|
By providing a framework we can override requests by policy, and also
|
||||||
|
control requests from random services.
|
||||||
|
You also can't set latencies unless you're the root user, which is not
|
||||||
|
suitable for the desktop use case.
|
||||||
|
</doc:para>
|
||||||
|
<doc:para>
|
||||||
|
Of course, you can do if you really want, but then you loose the
|
||||||
|
benefits of the query interface and the policy override,
|
||||||
|
and have to run your application as root.

Set the minimum acceptable latency of the system.

Setting this value tells the system to not attempt latencies below this setting.
|

This may be useful in a data center or server room, when you want to override the

|
latency requests from applications.
|
||||||
|
This may be required if the server room is operating outside a standard thermal
|

|
or power envelope, and an override is required.

You do not have to use this method during normal operation.
