Hello,I have 3 graphic cards in my PC. The default is the Intel integrated mobo
gpu. I use this as primary. The other are the RTX 2080 ti and the GTX 1060. I'm
trying to make the passthru of my Nvidia RTX 2080 ti from FreeBSD to Ubuntu
21.04 emulated with bhyve. Unfortunately an error that seems a bug prevents me
from completing the task. First of all I want to show you what is the FULL pci
configuration on my PC :

    device     = 'uPD720201 USB 3.0 Host Controller'
    class      = serial bus
    subclass   = USB

Then,according with the wiki : https://wiki.freebsd.org/bhyve/pci_passthru ; I
have masked the pci devices of the graphic card inside the file
/boot/loader.conf like this :

/boot/loader.conf

pptdevs="1/0/0 1/0/1 1/0/2 1/0/3"

but I tried also different combinations,like these :

pptdevs="1/0/0 1/0/2 1/0/3"

or

pptdevs="2/0/0"

or

pptdevs="2/0/0 2/0/1"

and I have rebooted the PC and I've seen that all relevant pci devices have
been masked correctly.

ppt0@pci0:1:0:0:    class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1e04 subvendor=0x19da subdevice=0x2503
    vendor     = 'NVIDIA Corporation'
    device     = 'TU102 [GeForce RTX 2080 Ti]'
    class      = display
    subclass   = VGA

ppt1@pci0:1:0:1:    class=0x040300 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x10f7 subvendor=0x19da subdevice=0x2503
    vendor     = 'NVIDIA Corporation'
    device     = 'TU102 High Definition Audio Controller'
    class      = multimedia
    subclass   = HDA

ppt2@pci0:1:0:2:    class=0x0c0330 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1ad6 subvendor=0x19da subdevice=0x2503
    vendor     = 'NVIDIA Corporation'
    device     = 'TU102 USB 3.1 Host Controller'
    class      = serial bus
    subclass   = USB

ppt3@pci0:1:0:3:    class=0x0c8000 rev=0xa1 hdr=0x00 vendor=0x10de
device=0x1ad7 subvendor=0x19da subdevice=0x2503
    vendor     = 'NVIDIA Corporation'
    device     = 'TU102 USB Type-C UCSI Controller'
    class      = serial bus


So,I tried to run the Ubuntu virtual machine with this command :


bhyve -S -c 4 -m 8G -w -H \
        -s 0,hostbridge \
        -s 1,virtio-blk,/mnt/da1p1/vms/os/ubuntu-budgie-gpu/ubuntu-2104-gpu.img
\
        -s 2,passthru,1/0/0 \
        -s 2:1,passthru,1/0/1 \
        -s 2:2,passthru,1/0/2 \
        -s 2:3,passthru,1/0/3 \
        -s 6,virtio-net,tap0 \
        -s 20,hda,play=/dev/dsp8,rec=/dev/dsp8 \
        -s 29,fbuf,tcp=0.0.0.0:5900,w=1440,h=900 \
        -s 30,xhci,tablet \
        -s 31,lpc -l com1,stdio \
        -l bootrom,/usr/local/share/uefi-firmware/BHYVE_UEFI.fd \
        vm0


sometime the VM freezes,sometimes it gives the error "bhyve Assertion failed:
(!err), function hda_init, file /usr/src/usr.sbin/bhyve/pci_hda.c, line 400"

It seems like a bug or what ? Suggestions to give me ? thanks.
