It's not used by the host. FreeBSD is using the geforce 1060. And on the BIOS I have set up the 1060 as default. I know that I can't pass through a gpu that I'm using. And the third gpu is the geforce rtx 2080 ti that I can actually pass.
Actually I have 3 gpus : ppt4@pci0:0:2:0: class=0x038000 rev=0x02 hdr=0x00 vendor=0x8086 device=0x3e98 subvendor=0x1458 subdevice=0xd000 vendor = 'Intel Corporation' device = 'CoffeeLake-S GT2 [UHD Graphics 630]' class = display vgapci0@pci0:1:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1c02 subvendor=0x19d a subdevice=0x2438 vendor = 'NVIDIA Corporation' device = 'GP106 [GeForce GTX 1060 3GB]' class = display subclass = VGA hdac0@pci0:1:0:1: class=0x040300 rev=0xa1 hdr=0x00 vendor=0x10de device=0x10f1 subvendor=0x19d a subdevice=0x2438 vendor = 'NVIDIA Corporation' device = 'GP106 High Definition Audio Controller' class = multimedia subclass = HDA ppt0@pci0:2:0:0: class=0x030000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1e04 subvendor=0x19d a subdevice=0x2503 vendor = 'NVIDIA Corporation' device = 'TU102 [GeForce RTX 2080 Ti]' class = display subclass = VGA ppt1@pci0:2:0:1: class=0x040300 rev=0xa1 hdr=0x00 vendor=0x10de device=0x10f7 subvendor=0x19d a subdevice=0x2503 vendor = 'NVIDIA Corporation' device = 'TU102 High Definition Audio Controller' class = multimedia subclass = HDA ppt2@pci0:2:0:2: class=0x0c0330 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1ad6 subvendor=0x19d a subdevice=0x2503 vendor = 'NVIDIA Corporation' device = 'TU102 USB 3.1 Host Controller' class = serial bus subclass = USB ppt3@pci0:2:0:3: class=0x0c8000 rev=0xa1 hdr=0x00 vendor=0x10de device=0x1ad7 subvendor=0x19d a subdevice=0x2503 vendor = 'NVIDIA Corporation' device = 'TU102 USB Type-C UCSI Controller' class = serial bus As you can see,I'm using the ppt driver on the gpus that I'm not using.
