DF-3978 runtime environment (verification run of 2026-10-12)

Guest OS    : DragonFly dfbsd 6.5-DEVELOPMENT #0: Thu Jul 2 06:02:54 UTC 2026
              (rev 600519) x86_64, kernel /boot/kernel/kernel (no KASLR,
              text base 0xffffffff80200000)
Compiler    : cc 8.3 [DragonFly] Release/2019-02-22
QEMU        : qemu-system-x86_64 7.2.22 (Debian 1:7.2+dfsg-7+deb12u18+b3)
              Private TCG instance used for verification:
                -accel tcg,thread=multi -cpu qemu64,+svm,+npt -m 2048 -smp 1
                -drive file=<throwaway qcow2 overlay over dfbsd-qemu/disk.qcow2>,if=virtio
                -netdev user,id=n0,hostfwd=tcp:127.0.0.1:5522-:22
                -d int,cpu_reset -D qemu-int.log
              (the harness disk itself is opened read-only as the backing
              file; the overlay with all test state was discarded after)
Host CPU    : Intel Xeon E3-1275 v5 -- no SVM flag (/proc/cpuinfo),
              /dev/kvm present.  KVM cannot expose SVM on this host.
Stock harness guest (-enable-kvm, default qemu64 CPU model):
              kldload nvmm -> "nvmm: cpu not supported",
              module_register_init: MOD_LOAD (nvmm) error 45
              (neither VMX nor SVM CPUID bits under qemu64/KVM-Intel;
              /dev/nvmm absent after boot).  Verified live 2026-10-12.
NVMM (test) : kldload of nvmm.ko built from /usr/src/sys with the
              disclosed test-only NRIPS ident-gate relaxation
              (test_relax.diff); without it the stock driver prints
              "nvmm: SVM-NRIPS not supported" and refuses the TCG CPU
              (QEMU 7.2 TCG does not expose CPUID.8000000A:EDX bit 3).
              With it: "nvmm: attached, using backend x86-svm";
              /dev/nvmm crw-r----- root:nvmm 0640.
Unpriv user : uid=1002(testnv) gid=1002(testnv) groups=1002(testnv),90(nvmm)
Rig offsets : OFF(p_pid)=0x5c OFF(p_ucred)=0x10 OFF(p_list)=0x0
              OFF(cr_uid)=0x40 OFF(cr_ruid)=0xa0 OFF(cr_svuid)=0xa4
              (sizeof ucred=256, proc=1208; validated live via pfind())
CPU model   : qemu64 under TCG -- no SMEP, no SMAP, no KASLR
