This was the error : I wanted to passthru my CoffeeLake-S GT2 [UHD Graphics 630] : ppt4@pci0:0:2:0: class=0x038000 rev=0x02 hdr=0x00 vendor=0x8086 device=0x3e98 subvendor=0x145 8 subdevice=0xd000 vendor = 'Intel Corporation' device = 'CoffeeLake-S GT2 [UHD Graphics 630]' class = display bhyve -S -c sockets=1,cores=2,threads=2 -m 4G -w -H -A \ -s 0,hostbridge \ -s 1,nvme,/dev/$vmdisk0,bootindex=1 \ -s 2,ahci-hd,/dev/$vmdisk2 \ -s 3,ahci-hd,/dev/$vmdisk4 \ -s 4,passthru,0/2/0 \ -s 7,virtio-net,tap4 \ -s 10,hda,play=/dev/dsp,rec=/dev/dsp \ -s 29,fbuf,tcp=0.0.0.0:5904,w=1500,h=950 \ -s 30,xhci,tablet \ -s 31,lpc \ -l bootrom,/usr/local/share/uefi-firmware/BHYVE_BHF_CODE.fd \ vm4 < /dev/null & sleep 2 && vncviewer 0:4 Exited with this error : bhyve: Warning: Unable to reuse host address of Graphics Stolen Memory. GPU passthrough might not work properly. bhyve: gvt_d_setup_opregion: Unable to get OpRegion base and length bhyve: gvt_d_init: Unable to setup OpRegion device emulation initialization error: Operation not supported by device The solution suggested by Corvin has been the following one : Make sure your GPU is booted in UEFI and not CSM mode. -- You are receiving this mail because: You are the assignee for the bug.
