nvidia-smi and nvtop shows different results. is libva-nvidia-driver truly working?

[fxzzi]

as shown by nvtop here:

there seems to be no decoder usage by any program. Even those which are called N/A (I think the compute N/A is librewolf)

Under nvidia-smi it seems to be a similar story:

no compute process is shown here, which is strange.

Under nvidia-smi pmon there also seems to be no decoder usage shown:

However, under nvidia-smi dmon there is actually decoder usage, does this mean that the driver is working?

That's certainly odd. I would say no there's no hardware video decode happening, at least not in librewolf or electron. But as to what is causing the GPU to report that there is decode occurring I have no idea.

Hardware decoding is working:

Hardware decoding is working:

yeah, you're right. That 9% is the same shown in nvidia-smi pmon. And it does go to 0% when the video is paused.

Just a little strange that both nvidia-smi and nvtop are failing to specify that librewolf is the C process

[fxzzi]

I will close this since it does seem like it is making a change to decode usage.

Yeah, looks like 570 drivers fixed the monitoring issue. Nvidia smi and nvtop both correctly show the compute process now:
