Maybe I forget to setup something correctly,but :

1) I've removed the xf86-video-intel driver from the system with : pkg remove xf86-video-intel

2) i haven't any i915kms = or legacy intel module inside the memory :
<= /span>

# kldstat | grep i915 : nothing
# kldstat | grep kms : nothing
# kldstat | grep intel : nothing

3) this is my xorg.conf (where is there is no t= race of intel driver)

As you can see,= I'm using the ppt driver on the gpus that I'm not using.

I thought in= general we couldn't pass the GPU if it was being used by the host? (Th= us you would need to have two GPUs, one to allow the host to display its ou= tput and one to passthrough. Unless the host is completely headless).

Hello.

<= /span>
I've tried to passthru my CoffeeLake-= S GT2 [UHD Graphics 630] on a Linux VM but it failed. This graphic card :

ppt4@pci0:0:2:0: =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0cla= ss=3D0x038000 rev=3D0x02 hdr=3D0x00 vendor=3D0x8086 device=3D0x3e98 subvend= or=3D0x1458 subdevice=3D0xd000

=C2=A0=C2=A0=C2=A0class =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=3D display

be= low there are the bhyve parameters that I've used :

<= /span>
bhyve -S -c sockets=3D1,cores=3D2,threads=3D2 -m 4G -w -H -A \
-s 0,hostbridge \
-s 1,nvme,/dev/$vmdisk0,bootindex=3D1 \
-s 2,ahci-hd,/dev/$vmdisk2 \

-s 31,lpc \
-l bootrom,/usr/local/share/uefi-firmware/BHYVE_BHF_CODE.fd \
vm4 < /dev/null & sleep 2 && vncviewer 0:4=

this is the error I get :

bhyve: Warning: Unable to reuse host address of Graphics Stolen Memor= y.
GPU passthrou= gh might not work prope= rly.
bhyve: gvt_d_setup_opregion: Unable to get OpReg= ion base and length
bhyve: gvt_d_init: Unable to setup OpRegion
device emulation initialization error: Operation not supported by devic= e

Should I apply some patches ? I know for su= re that I can pass through this kind of gpu,using the Corvin patches,but I = don't know if I have found a bug that should be fixed. Let me know.
