With Pierre-Loup's desktop we have an issue where the reported=
 VRAM and CPU
visible VRAM are totally off.

e.g. the last report we had kernel reported total VRAM size of
0xfffffffb3070f000 (16.0 EiB) and a visible VRAM size of 0x86135000 (2.09 G=
iB).

The system is a large aperture system, so expected is ~8 GiB for both, and =
it
is most of the time. The system typically boots in a good state and eventua=
lly
after a while transitions to a bad state and sometimes it transitions back.

We have not been able to find a pattern and on one of the earlier cases the
debugfs vram_mm file reported reasonable size & utilization.


The kernels that have been tried include amd-staging-drm-next and a released
kernel (need to look up whether it was 4.15 or 4.16 if that information is
needed)
