GPU power management for Intel hardware on Linux

intel-power-control

GPU power management for Intel hardware on Linux

Functionality

• Displays cpu online states, temperatures and gpu clock settings.
• Toggle cpu online states
• Throttling of gpu clock (also automatic)
• intel-power-control-helper changes settings as root user

Requirements

• C compiler (i.e. gcc)
• PyQt 6.x

Installation from PyPi (recommended)

# system-wide
sudo pip install intel-power-control
echo "%sudo ALL=(ALL) NOPASSWD: /usr/local/bin/intel-power-control-helper" | \
  sudo tee /etc/sudoers.d/intel-power-control

# OR as user
pip install intel-power-control --user
sudo chown root:root $HOME/.local/bin/intel-power-control-helper
sudo chmod 4755 $HOME/.local/bin/intel-power-control-helper

# run program
intel-power-control

Installation from source

WARNING: using this method, you have to take care of installing the required dependencies yourself (i.e. install PyQt using your distribution's package manager).

git clone https://github.com/jmechnich/intel-power-control.git

# compile
cd intel-power-control
make

# install to /usr/local
sudo make install

# OR install to local prefix
make install PREFIX=$HOME/.local
sudo chown root:root $HOME/.local/bin/intel-power-control-helper
sudo chmod 4755 $HOME/.local/bin/intel-power-control-helper

# run program
intel-power-control

Checking and fixing intel-power-control-helper permissions

The script intel-power-control-setup is supplied to set up the permissions for intel-power-control-helper correctly after installation.

Changing the look and feel

Use the -style commandline option to select a different theme. Available themes can be listed by calling the application with an invalid style argument, e.g. -style help.

intel-power-control's Issues

GPU clock limits get overridden by boost clock limit

I found that GPU clock limits do not work, under load the GPU still hits a max of 1250MHz in my case.

When looking through the code I fould no trace of gt_boost_freq_mhz which should be changed in a fashion similar to gt_max_freq_mhz.

Here is an example:

Max clock speed is set to 350. Boost clock speed is left untouched (default in my case is 1250). When the GPU encounters load, the GPU clock speed is increased to 1250MHz because the boost clock speed overrides the max clock speed.

Solution:

either change the boost clock speed together with max clock speed or offer separate limiter for boost clock speeds.

add dirname (argv [0]) to suidhelper search path

Most users will run intel-power-control from the git directory. And it will fail to find the helper, of course, since the git directory isn't in the PATH.

As a simple workaround, add the dirname of the Python program to the searched dir list in which():

     else:
-        for path in os.environ["PATH"].split(os.pathsep):
+        for path in os.environ["PATH"].split(os.pathsep) + [os.path.dirname (sys.argv[0])]:
             path = path.strip('"')

(normally, it would be easier to modify os.environ["PATH"] directly at the beginning of main(), but since you're setting suidhelper directly in a class constructor, which() will be called before main())

Constants not available as Qt attributes

I downloaded your application as an AUR package.

https://aur.archlinux.org/packages/intel-power-control-git

However, the package is outdated. I explicitly installed PyQt6 and PyQt6 SIP additionally and it worked. But then, it crashed when the "systray icon" is enabled because it cannot find the color constants under 'Qt'. When I turned the 'Qt.red' into 'Qt.GlobalColor.red' (in the /usr/bin/intel-power-control python script) then it works without crashing.

Is there something that I am missing for a normal functioning without hacking? Or are there differences in the PyQt API for Windows and Linux?

cannot overclocking the iGPU uhd770

i have a question,

my CPU is 13700k which ship with a UHD770, by default its max freq is 1600Mhz

i have set it value to 2000MHz in BIOS, but reboot to linux, boost freq still limit to 1600Mhz.

how can i overclock it? thank you!

Only 10 of 12 cpu-cores (logical cores) are displayed

Hi,

I have an Intel i7 9750H 6-core cpu, which offers 12 Threads.
It seems that intel-power-control is displaying the logical cores, but not all of them:

Temperature values barely visible with dark theme

The thermal zones area in the GUI shows a column Temperature but the values are displayed in black color.

The other font adapts to the OS theme and is displayed in white. Ideally, the temperature values should also be displayed in the main colour of the OS theme.
