Similar motivation to other similar recent attempt[1].  But with an
attempt to have some shared code for this.  As well as documentation.

It is probably a bit UMA-centric, I guess devices with VRAM might want
some placement stats as well.  But this seems like a reasonable start.

Basic gputop support: https://patchwork.freedesktop.org/series/116236/
And already nvtop support: https://github.com/Syllo/nvtop/pull/204

[1] https://patchwork.freedesktop.org/series/112397/

I think the extra client id looks a bit superfluous since the ino of the file should already be unique and IIRC we have been already using that one.

Apart from that looks good to me,
Christian.

PS: For some reason only the two patches I was CCed on ended up in my inbox, dri-devel swallowed all the rest and hasn't spit it out yet. Had to dig up the rest from patchwork.
