Hi WizP, keep on trying, I've been trying some more too. Hopefully one of will get there. In short, I tried adding a binding in my Unraid go file. But what made more difference was I've changed my Ubuntu VM to use an i440 instead of Q35. I've stopped getting the memory conflict errors - which is great. However I'm getting an error regarding the vbios rom I'm passing through in the VM setup. Dmesg in the Ubuntu VM complains that it was expecting a 05xa header, but got something else. Which is really strange because that vbios I have here does start with 05xa. I'm going to try passing it in through a QEMU argument instead. Failing that might run the vbios through 'rom-parser' and see if it changes anything. -Simt

I'd appreciate it, if you could have a look. intel_uhd_605_vbios.zip I've attached the vbios file I have. I downloaded it from another forum, Proxmox maybe..? I've been trying to figure out where I got it from last week. But can't. If I remember I'll edit this post. Edit: Got the vbios from: https://forum.proxmox.com/threads/proxmox-6-0-gemini-lake-and-igd-graphics-passthrough-for-windows-10.60415/post-287483 -Simt

okay, I've been working through the solution from here: https://forum.proxmox.com/threads/proxmox-5-2-gemini-lake-and-igd-graphics-passthrough-for-ubuntu-18.47129/page-2 I'm good right until the very end. At that point in Proxmox, Steffen makes a new VM, with regular settings, but then he does this: Video: add PCI Device 0000 00:02.0 -> select advanced + select PCI-Express + Primary GPU + All Functions +ROM-Bar Sound (HDMI) add PCI Device 0000 00:0e.0 -> select advanced + select PCI-Express + All Functions +ROM-Bar And the resulting lines in the config file (I guess is Proxmox XML equivalent: hostpci0: 00:02,pcie=1,x-vga=1 hostpci1: 00:0e,pcie=1 I'm not sure how to do this in Unraid. Could anyone help please? And up to here with everything else, passthorugh isn't working. I tried adding a QEMU section at the end of the XML: <qemu:commandline> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=00:02.0,bus=pcie.0,x-vga=on'/> <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=00:0e.0,bus=pcie.0'/> </qemu:commandline> But this gives me an execution error on starting the VM: internal error: qemu unexpectedly closed the monitor: 2020-03-23T12:58:48.602152Z qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,id=hostdev0,bus=pcie.0,addr=0x2: IGD device 0000:00:02.0 cannot support legacy mode due to existing devices at address 1f.0 2020-03-23T12:58:48.760743Z qemu-system-x86_64: -device vfio-pci,host=00:02.0,bus=pcie.0,x-vga=on: vfio 0000:00:02.0: device is already attached By the way, when I look at what's at 1f.0 in Unraid (Unraid terminal> lspci -knn) I see: 00:1f.0 ISA bridge [0601]: Intel Corporation Device [8086:31e8] (rev 03) Lastly, I'll add that everything that Steffenprox did, tranlsated to a bunch of arguments that went into the Unraid sysconfig file. Mine looks like this: kernel /bzimage append intel_iommu=on vfio_virqfd vfio_pci vfio-pci.ids=8086:3185,8086:3198 modprobe.blacklist=snd_hda_intel,snd_hda_codec_hdmi,i915 pcie_acs_override=downstream,multifunction video=efifb:off,vesafb:off vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot

Hi Wizp, I saw that post early on in my efforts to get passthrough working. Back then it seemed way too arcane and complicated to try. But looking at it again now, it's like a nonchalant 'oh yeah, doesn't look to hard to follow, I could give that a good try.' I'm out camping at the moment (possibly last time for awhile as I just heard that some state borders are being shut here in Australia due to Coronavirus) But when we're back, I'll give it a try. -Simt

Hello, I'm hoping someone can help me figure this out and get passthrough working. I have an Asrock J4105 with an Intel Quad-core processor and onboard Intel UHD605 graphics. I've installed Unraid (loving it), but it's also a real desire of mine to use the machine as a media player. I've been trying to passthrough the UHD605 to a VM of Ubuntu. (Though I'll take any OS, if passthrough to it can work.). After much scouring of forums, I've gotten to a point where Ubuntu VM runs happily from the DVI output. But the video card is still never recognised properly and I can't get hardware acceleration to effectively play video files. A bare metal host install of Ubuntu works absolutely fine with the UHD605 card. In 'good' host Ubuntu settings I see this, and it's what I want: But in VM Ubuntu what I get instead is: My Unraid OS syslinux config is: Unraid OS: kernel /bzimage append pcie_acs_override=downstream,multifunction vfio-pci.ids=8086:0412,8086:a170 video=efifb:off,vesafb:off vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot I was using a modprobe.blacklist=.... But it didn't seem to make any difference. I'm even supplying a Video Rom bios of the UHD605 - which doesn't seem to make much difference either way. My VMS settings has PCIe override set to: Both, and VFIO Allow unsafe interrupts is: Yes. But still with all that, I can't get proper passthrough. When I look through Dmesg in Ubuntu I see the following error that I think is the culprit: [drm:i915_gem_init_stolen [i915]] *ERROR* conflict detected with stolen region: [mem 0x70000000-0x7fffffff] My Ubuntu VM log from Unraid looks like this: ErrorWarningSystemArrayLogin -overcommit mem-lock=off \ -smp 2,sockets=1,cores=2,threads=1 \ -uuid a2e91254-bd7c-8e33-fcf6-cc9a5f85ce29 \ -display none \ -no-user-config \ -nodefaults \ -chardev socket,id=charmonitor,fd=33,server,nowait \ -mon chardev=charmonitor,id=monitor,mode=control \ -rtc base=utc,driftfix=slew \ -global kvm-pit.lost_tick_policy=delay \ -no-hpet \ -no-shutdown \ -boot strict=on \ -device pcie-root-port,port=0xb,chassis=4,id=pci.4,bus=pcie.0,addr=0x1.0x3 \ -device pcie-root-port,port=0x8,chassis=1,id=pci.1,bus=pcie.0,multifunction=on,addr=0x1 \ -device pcie-root-port,port=0x9,chassis=2,id=pci.2,bus=pcie.0,addr=0x1.0x1 \ -device pcie-root-port,port=0xa,chassis=3,id=pci.3,bus=pcie.0,addr=0x1.0x2 \ -device ich9-usb-ehci1,id=usb,bus=pcie.0,addr=0x7.0x7 \ -device ich9-usb-uhci1,masterbus=usb.0,firstport=0,bus=pcie.0,multifunction=on,addr=0x7 \ -device ich9-usb-uhci2,masterbus=usb.0,firstport=2,bus=pcie.0,addr=0x7.0x1 \ -device ich9-usb-uhci3,masterbus=usb.0,firstport=4,bus=pcie.0,addr=0x7.0x2 \ -device virtio-serial-pci,id=virtio-serial0,bus=pci.2,addr=0x0 \ -blockdev '{"driver":"file","filename":"/mnt/user/domains/Ubuntu-19_2nd/vdisk1.img","node-name":"libvirt-1-storage","cache":{"direct":false,"no-flush":false},"auto-read-only":true,"discard":"unmap"}' \ -blockdev '{"node-name":"libvirt-1-format","read-only":false,"cache":{"direct":false,"no-flush":false},"driver":"raw","file":"libvirt-1-storage"}' \ -device ide-hd,bus=ide.2,drive=libvirt-1-format,id=sata0-0-2,bootindex=1,write-cache=on \ -netdev tap,fd=35,id=hostnet0,vhost=on,vhostfd=36 \ -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:2b:b5:3f,bus=pci.1,addr=0x0 \ -chardev pty,id=charserial0 \ -device isa-serial,chardev=charserial0,id=serial0 \ -chardev socket,id=charchannel0,fd=38,server,nowait \ -device virtserialport,bus=virtio-serial0.0,nr=1,chardev=charchannel0,id=channel0,name=org.qemu.guest_agent.0 \ -device vfio-pci,host=0000:00:02.0,id=hostdev0,bus=pcie.0,addr=0x2,romfile=/mnt/user/isos/VBIOS/intel_uhd_605_vbios/intel_uhd_605_vbios.rom \ -device vfio-pci,host=0000:00:0e.0,id=hostdev1,bus=pci.3,addr=0x0 \ -device usb-host,hostbus=1,hostaddr=2,id=hostdev2,bus=usb.0,port=1 \ -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny \ -msg timestamp=on 2020-03-18 12:43:33.085+0000: Domain id=3 is tainted: high-privileges 2020-03-18 12:43:33.085+0000: Domain id=3 is tainted: host-cpu char device redirected to /dev/pts/0 (label charserial0) 2020-03-18T12:43:34.592367Z qemu-system-x86_64: -device vfio-pci,host=0000:00:02.0,id=hostdev0,bus=pcie.0,addr=0x2,romfile=/mnt/disk1/isos/VBIOS/intel_uhd_605_vbios/intel_uhd_605_vbios.rom: IGD device 0000:00:02.0 cannot support legacy mode due to existing devices at address 1f.0 And the Dmesg grepped for only i915 stuff looks like this: You'll see there's errors about failing to initialise GPU and declaring it wedged! sim@sim-Standard-PC-Q35-ICH9-2009:~$ dmesg | grep -iC 3 "i915" [ 7.401484] intel_telemetry_core Init [ 7.413539] Invalid pltconfig, ensure IPC1 device is enabled in BIOS [ 7.443107] Invalid pltconfig, ensure IPC1 device is enabled in BIOS [ 7.516713] i915 0000:00:02.0: vgaarb: deactivate vga console [ 7.516844] [drm:i915_gem_init_stolen [i915]] *ERROR* conflict detected with stolen region: [mem 0x70000000-0x7fffffff] [ 7.521727] [drm] couldn't get memory information [ 7.572927] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
