updating nvidia-cudnn?

[Andreas Beckmann]

Hi lumin,

nvidia-cudnn is currently at version 8.2.4.15~cuda11.4 while 
nvidia-cuda-toolkit 11.5.2 recently made into sid.
Does nvidia-cudnn need to be updated for the newer cuda toolkit? What 
signficance does the enbedded version number have?
(Since there is no build dependency on nvidia-cuda-toolkit, cudnn falls 
through my regular testing raster.)

Is there anything we could do to have some minimal superficial 
autopkgtest for nvidia-cudnn (runnable on a host without nvidia gpu or 
driver available)? E.g. compile something ...

Since nvidia-cudnn is an downloader package and does not contain any 
non-free bits (at least I assume that it only depends on them), 
shouldn't that be rather in contrib instead of non-free?

Is cudnn available for other architectures besides amd64?
