Odroid N2+ gpufrequtils settings not working

[chatplosion]

Dear developers and community mebers,

since I installed Ubuntu 22.04, changes in file /etc/default/gpufrequtils are ignored or not passed to the device.

/sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/governor
/sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/min_freq
/sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/max_freq

They all stay unaffected as simple_ondemand, 124999998 and 9999999984.

What is wrong?

Update:

When I open a terminal and do the following:

Code: Select all

odroid@odroid-n2plus:~$ su root
Passwort: 
root@odroid-n2plus:/home/odroid# . /etc/default/gpufrequtils; echo ${GOVERNOR} > /sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/governor; echo ${MIN_FREQ} > /sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/min_freq; echo ${MAX_FREQ} > /sys/devices/platform/soc/ffe40000.gpu/devfreq/ffe40000.gpu/max_freq
root@odroid-n2plus:/home/odroid# 

The device now accepts the values from /etc/default/gpufrequtils until the next boot.

Is there a permission error or something else with udev?

What's your kernel version now? Please share the output of uname -a.
What' do you have in /etc/default/gpufrequtils?

My uname -a is:

And this is the contend of my /etc/default/gpufrequtils is:

Let me check again, how did you install 5.17 kernel? Since it's not tested enough and released yet, maybe you have installed it by yourself after download the package?

[chatplosion]

Yes, I installed it with apt. As you mention it, I also was surprised to see it available.
Shall I revert to newest 5.15 or 5.16?

Update:

I did downgrade the Kernel to 5.16.0-odroid-arm64 with the command

Code: Select all

sudo flash-kernel --force 5.16.0-odroid-arm64

and rebooted.
Now I have uname -a output:

Code: Select all

Linux odroid-n2plus 5.16.0-odroid-arm64 #1 SMP PREEMPT Ubuntu 5.16.16-202204242219~jammy (2022-04-24) aarch64 aarch64 aarch64 GNU/Linux

.

But the problem is the same.

I have a new bootlog attached.

Thanks, I think the problem can be resolved after updating the package odroid-base. Please check and let me know if it works.

Code: Select all

$ dpkg -l | grep odroid-base
ii  odroid-base                           5:22.04+202205110437~jammy        arm64        ODROID base package

It now works perfectly with governor and frequencies with the gpu!

I thank you a lot for boosting my odroid n2+ Ubuntu 22.04 a bit!

Who had thought that the udev rule for the gpu was broken?
This was indeed something unexpected.

I add the most recent bootlog for further analysis. Maybe other interesting things can be spotted.

Thanks, the log looks ok to me. This couldn't be fixed without your report.
