Python实现的Linux下CPU 频率管理软件源码，带GUI图形界面实现调整CPU频率

cpupower-gui -------------------- This program is designed to allow you to change the frequency limits of your cpu and its governor. The application is similar in functionality to `cpupower`.

[](https://repology.org/metapackage/cpupower-gui/versions) ## Repositories: ### Arch Linux and derivatives Packages exist in AUR as [`cpupower-gui`](https://aur.archlinux.org/packages/cpupower-gui/) ([`cpupower-gui-git`](https://aur.archlinux.org/packages/cpupower-gui-git/)), built from this repo. ### blackPanther OS To install `cpupower-gui` run `updating repos` to update the repositories and install by running `installing cpupower-gui`. ### Debian/Ubuntu and derivatives You can install `cpupower-gui` from the software manager or from the terminal by running: ```bash sudo apt install cpupower-gui ``` However, the version on Debian/Ubuntu repositories is way out of date. You can get the debian package of the latest version from the github releases page. ### Fedora/OpenSUSE You can install `cpupower-gui` by adding the repository from [openSUSE Build Service](https://software.opensuse.org//download.html?project=multimedia%3Aproaudio&package=cpupower-gui). For example, in Fedora 38 run the following as root: ```bash dnf config-manager --add-repo https://download.opensuse.org/repositories/multimedia:proaudio/Fedora_38/multimedia:proaudio.repo dnf install cpupower-gui ``` For OpenSUSE Tumbleweed: ```bash zypper addrepo https://download.opensuse.org/repositories/multimedia:proaudio/openSUSE_Tumbleweed/multimedia:proaudio.repo zypper refresh zypper install cpupower-gui ``` Note: The package repository is located at https://build.opensuse.org/package/show/multimedia:proaudio/cpupower-gui and the binaries for Fedora and Suse are built from the latest git revision of `cpupower-gui`. ### OpenMandriva You can install `cpupower-gui` from the official repository. ```bash dnf install cpupower-gui ``` # 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 $ cpupower-gui co -h usage: cpupower-gui config [-h] positional arguments: apply Apply cpupower configuration optional arguments: -h, --help show this help message and exit $ cpupower-gui config Applying configuration...
