org.freedesktop.UPower.PowerProfiles:
|
||||
@short_description: Power Profiles daemon
|
||||
|
||||
The power-profiles-daemon API is meant to be used by parts of the OS or
|
||||
desktop environment to switch system power profiles based on user choice,
|
||||
or user intent.
|
||||
|
||||
OS components would typically use the "Profiles" property to construct
|
||||
their UI (2 or 3 profiles available), and monitor the "ActiveProfile"
|
||||
and the "PerformanceDegraded" properties to update that UI. The UI
|
||||
would try to set the "ActiveProfile" property if the user selected
|
||||
a different one.
|
||||
|
||||
Note that the reason why the project exists and how it is different from
|
||||
existing projects is explained <ulink href=" https://gitlab.freedesktop.org/hadess/power-profiles-daemon/-/blob/master/README.md">
|
||||
in the project's README file</ulink>.
|
||||
|
||||
The object path will be "/org/freedesktop/UPower/PowerProfiles".
|
||||

<interface name="org.freedesktop.UPower.PowerProfiles">

<!--
|
||||
HoldProfile:
|
||||
|
||||
This forces the passed profile (either 'power-saver' or 'performance')
|
||||
to be activated until either the caller quits, "ReleaseProfile" is
|
||||
called, or the "ActiveProfile" is changed by the user.
|
||||
|
||||
This should be used programmatically by OS components when, eg. high-
|
||||
performance workloads are started with the "performance" profile, or
|
||||
battery will soon be critically low with the "power-saver" profile.
|
||||
|
||||
When conflicting profiles are requested to be held, the 'power-saver' profile
|
||||
will be activated in preference to the 'performance' profile.
|
||||
|
||||
Those holds will be automatically cancelled if the user manually switches
|
||||
to another profile, and the "ProfileReleased" signal will be emitted.

ProfileReleased:
|
||||
|
||||
This signal will be emitted if the profile is released because the
|
||||
"ActiveProfile" was manually changed. The signal will only be emitted
|
||||
to the process that originally called "HoldProfile".

PerformanceDegraded:
|

|

This will be set if the performance power profile is running in degraded
|
||||
mode, with the value being used to identify the reason for that degradation.
|
||||
As new reasons can be added, it is recommended that front-ends show a generic
|
||||
reason if they do not recognise the value. Possible values are:
|
||||
- "lap-detected" (the computer is sitting on the user's lap)
|
||||
- "high-operating-temperature" (the computer is close to overheating)
|
||||
- "" (the empty string, if not performance is not degraded)

<!--
|

Profiles:
|
||||
|
||||
An array of key-pair values representing each profile. The key named
|
||||
"Driver" (s) identifies the power-profiles-daemon backend code used to
|
||||
implement the profile.
|
||||
|
||||
The key named "Profile" (s) will be one of:
|
||||
- "power-saver" (battery saving profile)
|
||||
- "balanced" (the default profile)
|
||||
- "performance" (a profile that does not care about noise or battery consumption)
|
||||
|
||||
Only one of each type of profile will be listed, with the daemon choosing the
|
||||
more appropriate "driver" for each profile type.
|
||||
|
||||
This list is guaranteed to be sorted in the same order that the profiles
|
||||
are listed above.

<property name="Profiles" type="aa{sv}" access="read"/>
|

|

<!--
|

Actions:
|
||||
|
||||
An array of strings listing each one of the "actions" implemented in
|
||||
the running daemon. This is used by API users to figure out whether
|
||||
particular functionality is available in a version of the daemon.

|

<!--
|

ActiveProfileHolds:
|

A list of dictionaries representing the current profile holds.

The keys in the dict are "ApplicationId", "Profile" and "Reason",

and correspond to the "application_id", "profile" and "reason" arguments
|
||||
passed to the HoldProfile() method.
