SavageAUS Posted July 11, 2019 Share Posted July 11, 2019 (edited) Hi guys, Just wondering if this group would be causing any issue passing through the GTX1050ti to a VM? IOMMU group 1:[8086:1901] 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor PCIe Controller (x16) (rev 07) [10de:1c82] 01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1) [10de:0fb9] 01:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1) That's all that is in that group but when i boot the VM i get a black screen. *-display UNCLAIMED description: VGA compatible controller product: GP107 [GeForce GTX 1050 Ti] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:de000000-deffffff memory:c0000000-cfffffff memory:d0000000-d1ffffff ioport:e000(size=128) memory:df000000-df07ffff *-display UNCLAIMED description: VGA compatible controller product: ASPEED Graphics Family vendor: ASPEED Technology, Inc. physical id: 0 bus info: pci@0000:04:00.0 version: 30 width: 32 bits clock: 33MHz capabilities: pm msi vga_controller bus_master cap_list configuration: latency=0 resources: memory:dc000000-dcffffff memory:dd000000-dd01ffff ioport:d000(size=128) memory:c0000-dffff Edited July 11, 2019 by SavageAUS Quote Link to comment
SavageAUS Posted July 11, 2019 Author Share Posted July 11, 2019 Technically I have 2 gpus, 1 iGPU ASPEED and the 1050 so unRAID should be using the ASPEED which would leave the 1050 available yeah?Sent from my iPhone using Tapatalk Quote Link to comment
JQNE Posted July 11, 2019 Share Posted July 11, 2019 I think I had samekind problem in past. I think adding to Syslinux Configuration append pci=noaer got my GPU passthrough working. You get there on MAIN tab and under boot device click Flash. At left of your usb memory stick model. Here is my syslinux configuration code you to get my idea: default menu.c32 menu title Lime Technology, Inc. prompt 0 timeout 50 label Unraid OS menu default kernel /bzimage append pci=noaer vfio-pci.ids=1912:0014 pcie_acs_override=downstream initrd=/bzroot label Unraid OS GUI Mode kernel /bzimage append pcie_acs_override=downstream initrd=/bzroot,/bzroot-gui label Unraid OS Safe Mode (no plugins, no GUI) kernel /bzimage append initrd=/bzroot unraidsafemode label Unraid OS GUI Safe Mode (no plugins) kernel /bzimage append initrd=/bzroot,/bzroot-gui unraidsafemode label Memtest86+ kernel /memtest I added pci=noaer at first after that append. I'm not expert on Unraid and I might have added also: pcie_acs_override=downstream, vfio-pci.ids=1912:0014 So try with your own risk! Inform me what happens! Quote Link to comment
SavageAUS Posted July 11, 2019 Author Share Posted July 11, 2019 I thought that was only needed if you couldn’t add a device to a vm? I can add the gpu to the vm but I just get a black screen. I’ll try dumping the vbios later and see if that works. Sent from my iPhone using Tapatalk Quote Link to comment

The PCI root address for both is 01:00. 13 minutes ago, SavageAUS said: I’ll try dumping the vbios later and see if that works. That's where I would placing my bets, if it was me.

SavageAUS Posted July 11, 2019 Author Share Posted July 11, 2019 Do you know if we can dump the vbiis from unraid? Gotta be an easier way than either removing the gpu or installing windows. I do have a windows to go USB stick I can boot into though. Sent from my iPhone using Tapatalk Quote Link to comment
SavageAUS Posted July 12, 2019 Author Share Posted July 12, 2019 Im still getting a blank screen. I cannot move my GPU as i only have 1 slot Quote Link to comment
SavageAUS Posted July 12, 2019 Author Share Posted July 12, 2019 My next course of action unless any other suggestions happen is to disable to ASPEED iGPU hopefully and see if then I can pass through the primary 1050. Sent from my iPhone using Tapatalk Quote Link to comment
SavageAUS Posted July 13, 2019 Author Share Posted July 13, 2019 Insert sad faceI feel real stupid now. It’s all working the way it should, needs some tinkering but GPU pass through is fine. Issue was the hdmi cable Sent from my iPhone using Tapatalk Quote Link to comment
