From: Michel Dänzer <[email protected]>
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
