Is the number of mapped buffers really useful, as opposed to the total
size of buffer mappings? Even if it was the latter though, it doesn't
show which mappings are for BOs in VRAM vs GTT, does it? Also, even the
total size of mappings of BOs currently in VRAM doesn't directly reflect
the pressure on the CPU visible part of VRAM — only the BOs which are
actively being accessed by the CPU contribute to that.
