Vega 3 gets 0% use about mangohud HOT 14 CLOSED

Back to the actual issue were on, as far as I know I can't do anything to fix the AMD gpu load either, it's up to the amdgpu kernel devs to fix (I think)

@ViNi-Arco most likely that program uses libXNVCtrl instead, which does support older cards. libXNVCtrl has been mentioned as a possible replacement for NVML before, but I haven't had too much time to look into if it's a good idea or not. Either way! sadly you cannot view your gpu load with mangohud as of yet and we can't fix it right now at least

What does cat /sys/class/drm/card*/device/gpu_busy_percent output?

What does cat /sys/class/drm/card*/device/gpu_busy_percent output?

Invalid Argument

Do I need to install any packages?

I'm using Mesa-ACO

from mangohud.

For some reason gpu_busy_percent doesn't support Vega 3 then.
Can you try radeon-profile or radeontop? If these work then using ioctl instead might work.

Maybe adding amdgpu.ppfeaturemask to kernel command line might help like amdgpu.ppfeaturemask=0xfffd7fff

from mangohud.

I have exactly the same issue on my notebook with Vega10.

cat /sys/class/drm/card*/device/gpu_busy_percent

also returns Invalid Argument.
Using Oibaf drivers on Ubuntu 19.10 with ACO enabled.

I will test this later, thanks 😁

@BNandroid did you try it and if so did it work?

hi, it happens to me too, I have Nvidia card, see does not show the use of the GPU nor the processor temperature:

I tried everything, still 0%: /

@ViNi-Arco your 0% gpu load is probably because your Nvidia card is not supported in NVML, what GPU is it? why the cpu temp isn't showing I don't know, what CPU is it?

from mangohud.

Good morning @flightlessmango, I have an EVGA GTX 650, it has NVML support, because in MSI Afterburner I can see the GPU usage and the CPU Temp, my Processor is the E8400 rev.E0

from mangohud.

@ViNi-Arco is this command able to get the load %?
nvidia-smi --query-gpu=utilization.gpu --format=csv,noheader

from mangohud.

Hi, @flightlessmango, the terminal reports this:

Which is at least strange because on the Nvidia Panel you can see the GPU usage:
