Hi everyone,

I'm trying to get NVIDIA GPU passthrough working with bhyve on=20 FreeBSD 15.0-RELEASE-p5, using Corvin K=C3=B6hne's nvidia-wip branch:

https://github.com/Beckhoff/freebsd-src/tree/p= hab/corvink/15.0/nvidia-wip

The VM fails to start with the following error before the guest even = boots:

bhyve: bootrom_alloc: vm_mmap_mapseg: Invalid argument

---

**Hardware**

- Motherboard: Gigabyte Z390 AORUS PRO

- CPU: Intel Core i9-9900K

- GPU: ZOTAC RTX 2080 Ti (0x10de:0x1e04, subvendor 0x19da, subdevice = 0x2503)

---

**Host**

- FreeBSD 15.0-RELEASE-p5 (kernel GENERIC, amd64)

- vmm.ko compiled from Corvin's `phab/corvink/15.0/nvidia-wip` br= anch

- bhyve compiled from the same branch

- libvmmapi.so.6 produced by the Corvin branch build

---

---

**Root cause analysis (via ktrace)**

---

Tracing bhyve with `ktrace` reveals the following sequence:


  1. `openat("/dev/vmmctl", O_RDWR)` =E2=86=92 success

  2. `ioctl(VM_MMAP_GETNEXT)` =E2=86=92 success

  3. `ioctl(VM_MMAP_MEMSEG)` =E2=86=92 **errno 22 (EINVAL)**

=

The failure is inside `bootrom_alloc()` =E2=86=92 `vm_mmap_memseg()` = when trying to map the `VM_BOOTROM` memory segment.

Digging into `lib/libvmmapi/vmmapi.c`, the function=20 `vm_alloc_memseg()` first calls `vm_get_memseg()` to check if the=20 segment already exists. If it returns success with `len =3D=3D 0` (segment= =20 not yet allocated), it should proceed to call


`VM_ALLOC_MEMSEG` ioctl to create the segment. However, `VM_ALLOC_MEM= SEG` is **never called** in the ktrace output.


<= p dir=3D"auto"> The result is that `seg->object =3D=3D NULL` in the kernel when=20 `vm_mmap_memseg()` is later called for `VM_BOOTROM`, which returns=20 `EINVAL`.

---

**Workaround found**

---


Replacing `libvmmapi.so.6` (from the Corvin build) with the system stock `libvmmapi.so.7` fixes the bootrom issue =E2=80=94 the VM boots=20 successfully. However, this introduces a new problem: `bhyvectl=20 --vm=3Dname --create` returns `Operation not permitted` (EPERM) because=20 the stock libvmmapi uses different ioctls that vmm.ko Corvin doesn't=20 handle correctly.

What is the correct fix for `vm_alloc_memseg()` in the Corvin=20 libvmmapi to ensure `VM_ALLOC_MEMSEG` is properly called for=20 `VM_BOOTROM`? Is there a known patch or workaround that keeps=20 compatibility with vmm.ko Corvin while fixing the bootrom allocation?

Thanks!

N= VIDIA GPU passthrough should work with stock 15.0, no patches required.

From my limited e= xperiments FreeBSD 15 has what is necessary for Nvidia passthru, but, and i= t may be GPU dependent, some Nvidia cards absolutely needed the hypervisor = ID to be 'KVM KVM\0\0' and not 'bhyve bhyve'.
