gpu-mon is giving a wrong GTT% for my RX 570 cards because the AMDGPU info for GTT total is actually the VRAM total (with AMDGPU 21.10 drivers).
GTT% and totals are correct for my RX 5600 XT card.
The GTT total memory should be the same as the system total, not the VRAM total.
From my RX 570 system:
$ cat /sys/class/drm/card1/device/mem_info_gtt_total
4294967296
$ cat /sys/class/drm/card1/device/mem_info_vram_total
4294967296
$ free -b
total used free shared buff/cache available
Mem: 16635121664 5139062784 3848486912 318304256 7647571968 10830524416 ...etc..
I've vaguely noticed something amiss for a while, but only just now investigated it, so I don't know if this issue was in the prior AMDGPU driver. Has anyone loaded the newest AMD drivers, 21.20, who can test whether the GTT total bug for "legacy cards" (Polaris, Ellesmere) has been corrected? If the bug is still there, perhaps a fix could be to use the system total memory from something like the 'free' command in lieu of the mem_info_gtt_total content?
