Guest: DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul  2 06:02:54 UTC 2026 (X86_64_GENERIC, kern.osreldate 600519)
Compiler: cc 8.3 [DragonFly] Release/2019-02-22
Loaded klds: kernel, ehci.ko, xhci.ko (radeon.ko NOT loaded — nothing to attach to)
Driver present: /boot/kernel/radeon.ko, /boot/kernel/drm.ko,
  /boot/kernel/radeonkmsfw_{BARTS,TURKS,CAICOS,CAYMAN,ARUBA}_{pfp,me,rlc,mc,smc}.ko
AMD/ATI PCI devices on this guest: NONE (virtio-only QEMU/KVM; vgapci0 is the
  QEMU stub chip=0x11111234; verified as root: pciconf -l | grep 0x1002 -> empty)
=> The ni_dpm code path is hardware-gated and cannot execute on this guest;
   verification is source-level + userspace logic harness (verbatim call graph
   and struct offsets), matching the DF-3610/DF-3646 family methodology.
