SUMMARY
GPU sensors do not work with intel hd 4000 iGPU of my laptop.

STEPS TO REPRODUCE
1. add System Monitor Sensor widget to desktop
2. open widget settings and click on "Sensors details" section
3. click on "Text-only sensors" row
4. click on GPU > All GPUs and add all available sensors
5. close widget settings by clicking on "OK" button

OBSERVED RESULT
as we can see in the attached screenshot, GPU sensors do not work

EXPECTED RESULT
GPU sensors should work with iGPUs

SOFTWARE/OS VERSIONS
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.21.80
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2

Comment 1 David Redondo 2021-05-10 11:56:06 UTC 
Yeah there's currently no way to get this info (without root)
Comment 2 Arjen Hiemstra 2021-05-10 15:06:57 UTC 
There is no standard API for GPU monitoring and the intel driver also does not expose anything. intel-gpu-top or whatever the thing was called uses performance counters for this, which require root and are actually not really meant to be used for this. In comparison, amdgpu exposes a number of sysfs files which expose information about the GPU which can be read without needing root.

It would be great if there was some standard way of getting this information, unfortunately I don't see it happening any time soon.
Comment 3 Nate Graham 2021-05-10 23:19:54 UTC 
Can we hide these sensors when they don't have valid data?
Comment 4 David Edmundson 2021-05-23 23:01:28 UTC 
>Can we hide these sensors when they don't have valid data? 

We should.

Can I see `kstatsviewer --list`

Comment 6 Arjen Hiemstra 2021-06-03 10:13:35 UTC 
Git commit 0639a7f9b959e0ce74f798acee801928de4369d9 by Arjen Hiemstra.
Committed on 03/06/2021 at 10:13.
Pushed by ahiemstra into branch 'master'.

Only add "All GPUs" sensors when there is at least one GPU with statistics

Otherwise we have an empty "GPU" entry that does nothing when there are
no supported GPUs.
