We actually have a helper for that in amdgpu_vram_mgr_vis_size().

Apart from that if the problem only occurse after a certain time it looks l=
ike
we have a mismatch between adding the pinned size and subtracting it again.=
 Or
alternatively some sort of memory corruption.

Have you tried running it with KASAN enabled for a while?
