[PATCH 0/3] drm/amdgpu: Final fix for https://bugs.freedesktop.org/106872

[michel@xxxxxxxxxxx (Michel Dänzer)]

From: Michel Dänzer <michel.daenzer@xxxxxxx>

Finally got confirmation from the debugging patch in the bug report
that these values need to be atomic, or they can get corrupted.

Patch 1 is so that it's not necessary to use two atomic values for
computing the amount of non-pinned CPU visible VRAM, as that could
still give an inconsistent result if there are BOs being (un)pinned
concurrently.

Michel Dänzer (3):
  drm/amdgpu: Keep track of amount of pinned CPU visible VRAM
  drm/amdgpu: Make pin_size values atomic
  drm/amdgpu: Warn and update pin_size values when destroying a pinned
    BO
