From: Rob Clark <robdclark@chromium.org>

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

There is more do to here to remove my client->id fully (would now be 
dead code) so maybe easiest if you drop this patch and I do it after you 
land this and it propagates to our branches? I'd like to avoid pain with 
conflicts if possible..
