Include GDDR6(X) VRAM temperatures

[Bengt]

Is your feature request related to a problem? Please describe.
There is now a utility for reading VRAM temperatures under Linux:

https://github.com/olealgoritme/gddr6

Please include this data in gpustat.

Describe the solution you'd like

Maybe one can reuse the functionality from the gddr6 library?

Describe alternatives you've considered

One can also just use the gddr6 application as a stand alone, but that is a hassle.

Additional context

The GDDR6 application works fine for me without setting the kernel boot parameter under Ubuntu 22.04.3.

Interesting. This doesn't appear to be a part of the official pynvml bindings, but it's an additional low-level feature. We can make it integrated to gpustat (optionally, as it requires some C extensions) but the work would be not trivial. I may work on this later in the near future, but not very soon (contributions are welcome).

Thanks for considering this, @wookayin!

Yes, the gddr6 library reads VRAM temperatures directly from the GPU and thus requires superuser rights. nvidia-smi is also lacking this feature:
