# Usage
## Graphical
To change the frequency settings, select the CPU from the drop-down menu, adjust the sliders and click `Apply`.
Additionally, the cpu governor can be changed by selecting a governor from the drop-down menu.
Last, to apply the same settings to all CPUs, toggle the `All CPUs` switch (square icon on the top left).
There are two governor profiles available, `Performance` and `Balanced`.
The performance profile sets the governor for all CPUs to `performance`.
Similarly, the balanced profile set the governor to either `powersave` (if available) or to a scalling governor such as `ondemand` or `schedutil`.
These profiles can be selected either from the desktop icon or the tray icon actions.
There is an option to enable or disable a specific cpu.
This can be controlled via the the `Online` checkbox next to the `CPU` drop-down menu.
Initially, the checkbox displays the state of the cpu, i.e. if it is online or offline.
Note: If this checkbox is greyed-out, it means that this cpu is not allowed to go offline.
## Command-line
The governor profiles can be used from the command line.
The CPU settings can be applied from the command line using the appropriate subcommands.
These commands are: `config`, `frequency`, `energy` (system dependent), `profile`, `online/offline`.
Sorter aliases are indicated in square brackets in the help menu.
```bash
$ cpupower-gui -h
usage: cpupower-gui [-h] [--version] [-b] [-p] [--gapplication-service]
{[co]nfig, [freq]uency, [ene]rgy, [pr]ofile, [off]line,
[on]line} ...
cpupower-gui - Set the scaling frequencies and governor of a CPU
optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
-b, --balanced Change governor to balanced
-p, --performance Change governor to performance
--gapplication-service
Start gui from gapplication
subcommands:
Configuration commands
{[co]nfig, [freq]uency, [ene]rgy, [pr]ofile, [off]line, [on]line}
Change the settings from the command line
```
For example to switch all governors to performance run `cpupower-gui -p`.
Alternatively, the application actions can be executed via `gapplication`.
```bash
# Switch to balanced profile
gapplication action org.rnd2.cpupower_gui Balanced
# Switch to performance profile
gapplication action org.rnd2.cpupower_gui Performance
```
The `config` subcommand apply the default configuration as defined in the configuration files.
```bash

```
The `profile` subcommand applies the configuration based on the user-defined profiles.
```bash
$ cpupower-gui pr -h
usage: cpupower-gui profile [-h] [-l] [PROFILE]
positional arguments:
PROFILE Apply a cpupower profile
optional arguments:
-h, --help show this help message and exit
-l, --list List available cpupower profiles
$ cpupower-gui pr # Running profile without arguments is equivalent to `-l`
The available profiles are:
- Balanced
- Custom
- Performance
```
The `online` and `offline` subcommands set the specified CPUs on or off.
```bash
$ cpupower-gui on -h
usage: cpupower-gui online [-h] [-l] [LIST OF CPUS]
positional arguments:
LIST OF CPUS Set CPUs online
optional arguments:
-h, --help show this help message and exit
-l, --list List online CPUs

The following CPUs are online: [0, 1, 2, 3]
$ cpupower-gui off 3
Setting CPU3 offline...
OK
$ cpupower-gui off
The following CPUs are online: [3]
```
The `energy` subcommand is only available on Intel systems and it can be used to query or set the energy performance preferences.
```bash
$ cpupower-gui energy -h
usage: cpupower-gui energy [-h]
[--pref {default,performance,balance_performance,balance_power,power} | --list-energy-preferences [LIST OF CPUS]]
optional arguments:
-h, --help show this help message and exit
--pref {default,performance,balance_performance,balance_power,power}
set a global energy profile
--list-energy-preferences [LIST OF CPUS]
list available energy performance preferences
(Default: all cpus)
```
Here is an example of setting the preference to `default`.
```bash
$ cpupower-gui ene --pref default
Setting energy performance preference to: default
Set CPU 0 to default
Set CPU 1 to default
Set CPU 2 to default
```
### Profiles and configuration
Since version `0.9.0` the command line supports setting the CPUs based on a configuration file and setting user-defined profiles.
To apply the default configuration just run `cpupower-gui config`.
To apply a profile run `cpupower-gui profile Performance`.
If the name of the profile contains spaces use quotes, e.g. `cpupower-gui profile "Custom profile"`.
### Intel P-State energy performance preferences
The last two options (`energy-performance-preference`, `list-energy-preferences`) are only available
on Intel systems that use the `intel_pstate` driver.
The `cpupower-gui energy --pref` option changes the preference to one of the available preferences for all CPUs.
The `list-energy-preferences` option accepts a list of CPUs written in the following format.
Comma separated values for listing CPU and hyphen for specifying a range.
For example `0-3` and `0,2-5,8` become `0,1,2,3` and `0,2,3,4,5,8` respectively.
If no value is passed it will report the preferences for all available cpus.
The current preference is indicated inside the parentheses.
```
$ cpupower-gui ene --list-energy-preferences 0-3
The available energy performance preferences are:
CPU 0:
- default
- performance
- balance_performance (Current)
- balance_power
- power
CPU 1:
- default
- performance
- balance_performance (Current)
- balance_power
- power
CPU 2:
- default
- performance
- balance_performance (Current)
- balance_power
- power
CPU 3:
- default
- performance
- balance_performance (Current)
- balance_power
- power
```
# System configuration and User profiles
## System configuration
Since version `0.9.0`, `cpupower-gui` can be configured using configuration files. The system configuration file is located in `/etc/cpupower_gui.conf`.
Users can add `.conf` files in `/etc/cpupower_gui.d` to override the default behaviour. The settings in these files override the behaviour of `cpupower-gui` system-wide.
Alternatively, users can add their configuration in `~/.config/cpupower_gui/`. The settings defined in that location take precedence over the ones defined in `/etc/`.
Currently, the only available settings are:
- `profile` under the `Profile` section,
and under the `GUI` section,
- `allcpus_default`
- `tick_marks_enabled`
- `frequency_ticks`
- `energy_pref_per_cpu`
Specifically,
- `profile` option sets the name of the profile to use when using `--apply-config` option (Default: Balanced).
- `allcpus_default` option controls the default state of the `To All CPUs` toggle of the GUI (Default: False).
- `tick_marks_enabled` option controls if tick marks should be displayed on the sliders (Default: True).
- `frequency_ticks` option controls if frequency is displayed above the tick marks (Default: True).
- `energy_pref_per_cpu` option allows you to select different energy profiles per CPU (Default: False).
## User profiles
User profiles are text files with a `.profile` suffix. These files should be placed either in `/etc/cpupower_gui.d/` or `~/.config/cpupower_gui/`.
Profiles placed in `/etc/cpupower_gui.d/` are then available to all users.
An [example profile](data/cpupower_gui.d/my_profile.profile.ex) is available at `/etc/cpupower_gui.d/my_profile.profile.ex`.
For more information about the profile format see [here](data/cpupower_gui.d/README).
By default, there are two auto-generated profiles named `Balanced` and `Performance`.
## systemd units
Since version 0.9.0, two systemd units have been added; a "system" and a "user" one.
The `cpupower-gui.service` applies the configuration as defined in `/etc/cpupower_gui.conf` during boot.
The `cpupower-gui-user.service` applies the user configuration during login (see notes below).
In a single-user environment the system service is preferable.
In a multi-user environment, the user service gives each user the ability to customise the profiles based on their needs.
When the user logs into the system, their settings will automatically apply.
Notes:
- The `cpupower-gui-user.service` currently depends on `graphical.target`. This is tested and works with Gnome Shell. If it doesn't work on a different display manager, open an issue.
- To apply the settings during login the user must be active and local to the system. This means that the user must have access to the hardware, so it won't work when the user logs in through `ssh`.
- To apply the settings over `ssh` the user will need root access.
## Enabling extra governors
By default, `cpupower-gui` will only show the available governors for each cpu.
To enable additional governors, such as `conservative` or `userspace`, copy the `scaling-governors.conf` file over to `/etc/modules-load.d`.
This way the new governors will be available across reboots.

## Build cpupower-gui
```bash
meson build --prefix /usr -Dsystemddir= -Dpkla= -Duse_libexec=
ninja -C build
```
### Meson options
#### `-Dsystemddir`
The `systemddir` option should point to the systemd directory.
If this option is not set the default is used (i.e. `/usr/lib/systemd`).
- The default value is valid for Arch/Fedora/OpenSUSE and derivatives.
- For Debian and Ubuntu based systems you should use `-Dsystemddir=/lib/systemd`.
##### `-Dpkla`
Since version **`0.9.0`** an additional option (**`-Dpkla`**) has been added for PolicyKit rules.
This option is set to **`false`** by default.
When `pkla` is set to `false` a polkit `.rules` file is installed under `/usr/share/polkit-1/rules.d/`.
When `pkla` is set to `true` a `.pkla` file is installed under `/var/lib/polkit-1/localauthority/10-vendor.d/`.
- The default value works Arch/Fedora/NixOS/OpenSUSE and derivatives.
- For Debian and Ubuntu based systems you should use `-Dpkla=true`
##### `-Duse_libexec`
Since version **`1.0.0`** an additional option (**`-Duse_libexec`**) has been added.
This option is set to **`false`** by default.
When `use_libexec` is set to `false` the helper program is installed under `/usr/lib/`.
When `use_libexec` is set to `true` the helper program is installed under `/usr/libexec/`.
- The default value works Arch/Fedora/NixOS/OpenSUSE and derivatives.
- For Debian and Ubuntu based systems you should use `-Duse_libexec=true`
