# Guest environment snapshot (taken 2026-09-15T19:01:23Z, read-only probes only) GUEST_UNAME="DragonFly dfbsd 6.5-DEVELOPMENT DragonFly 6.5-DEVELOPMENT #0: Thu Jul 2 06:02:54 UTC 2026 root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC x86_64" PCI_DISPLAY="vgapci0@pci0:0:2:0 class=0x030000 card=0x11001af4 chip=0x11111234 rev=0x02 (QEMU std VGA, NOT AMD)" AMD_PCI_DEVICES=0 # pciconf -l | grep -c 1002 -> 0 AMDGPU_MODULE="/boot/kernel/amdgpu.ko present (124519320 bytes, Jun 29 14:24)" DMESG="[drm] amdgpu kernel modesetting enabled." CONCLUSION="amdgpu code present and boot-time initialized, but zero AMD display devices on PCI: vega10_hwmgr_backend_init / any Vega10 powerplay path can never instantiate on this guest. All Vega10 hwmgr PoCs are hardware-gated (require an AMD Vega10 dGPU with an attacker-crafted VBIOS powerplay table)."
