Subject: [PATCH v4 0/6] drm: fdinfo memory stats

From: Rob Clark <robdclark@...omium.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

  drm: Add common fdinfo helper
  drm/msm: Switch to fdinfo helper
  drm/amdgpu: Switch to fdinfo helper
  drm/i915: Switch to fdinfo helper
  drm: Add fdinfo memory stats
  drm/msm: Add memory stats to fdinfo
