--- dmesg | grep -i amdgpu (after load)
[drm] amdgpu kernel modesetting enabled.
(no "amdgpu" device probe/attach lines — no supported hardware present)
--- sysctl -a | grep -i amdgpu_testing
amdgpu_testing_param_not_runtime_visible(0444_module_param)
(load-time module parameter only; default 0 per amdgpu_drv.c:85)
--- kldunload amdgpu
(unload of the ~65MB module exceeded the 120s command budget; guest remained
responsive afterwards — verified with a follow-up run_user 'id' which returned
uid=1001(maxx); module teardown completed or continued in background, no guest
state relevant to this finding was left dirty)
PROBE_DONE — no AMD hardware => amdgpu_device_init() never runs =>
amdgpu_test_moves() unreachable on this guest.
