SUMMARY
============================================================
* No AMD GPU hardware present in the QEMU guest (only QEMU std VGA).
* amdgpu / radeon / drm modules are NOT compiled into X86_64_GENERIC;
  amdgpu is a loadable KLD only.
* The vulnerable translation unit
  (sys/dev/drm/amd/powerplay/hwmgr/process_pptables_v1_0.c) is part of
  the amdgpu KLD module, built only when the module is loaded.
* The bug is unreachable at runtime on this guest: would require
  `kldload amdgpu` (root) + an AMD GPU device + a malicious VBIOS image
  (VFIO romfile or malicious FPGA GPU).
