GPU: vgapci0@pci0:0:2:0 class=0x030000 chip=0x11111234 (Bochs/QEMU stdvga)
     -- NOT an AMD ASIC; amdgpu DC cannot attach on this guest

$ ls /dev/dri
ls: /dev/dri: No such file or directory

$ kldstat | grep drm
(empty -- no drm/amdgpu modules loaded)

=> Hardware-gated for direct runtime triggering (no amdgpu ASIC, no DP MST
   hub). Verified instead with the proven verbatim-code rig (DF-4165/4247/
   4631 evidence class): production helper + lifecycle functions machine-
   extracted byte-identical from sys/ (checker-verified on this guest
   against /usr/src, the tree its running kernel was compiled from),
   compiled on this guest, driven through the exact kref sequences.
