RickD00 Posted April 25, 2020 Share Posted April 25, 2020 Hello, Im new to unraid. First first target is passthough my nv rtx 2070 to WIn and Ubuntu(Only one system will be run at the same time). My origional IOMMU group showns as : Basied on my understanding from youtube videos below, my IOMMU group 1 may not look right, so I switch to PCIe ACS override-downstream and got IOMMU group 12 which looks right to me. Then I got error: Afterwards, I update my Unraid OS to the following : kernel /bzimage append pcie_acs_override=downstream initrd=/bzroot vfio-pci.ids=10de:1ada,10de:1adb The error goes away. I also tried set PCIe ACS override to Both without vfio-pci update: But Im still having black screen. The rom Im using right now is extract from GPU-Z I also tried remove header by myself The only line I can find from rom that starting with 'u' is line 107. So I removed the line 1-106 However, NONE of my attempts works. I would appriacate for any suggestion and help My Win 10 config: Quote Link to comment

Hello, you were close when you got the Group 12 that I quoted from your post HOWEVER you were trying to only passthrough your RTX 2070s usb-c controller. vfio-pci.ids=10de:1ada,10de:1adb are your USB 3.1 controller and serial bus on your 2070. You need to be passing through the VGA Controller @ 10de:1f02 and your GPUs audio @ 10de:10f9. Also you must passthrough everything in group 12 including the RTX USB-C controller you were trying to passthrough before. Your vfio-pci.ids should look like this... vfio-pci.ids=10de:1f02,10de:10f9,10de:1ada,10de:1adb Once you do that make sure you select everything listed in Group 12 to passthrough in Unraid VM Win10 config PCI Devices. Hope this helps. Cheers! Quote Link to comment
RickD00 Posted April 27, 2020 Author Share Posted April 27, 2020 Hi @Carbongrip Thank you very much for the posting! I've updete vfio-pci.ids all group 12 and pass them into VM(as screenshot) But I still got a black screen Do you think this may related to gpu vbios ? Thanks! Quote Link to comment
Carbongrip Posted April 27, 2020 Share Posted April 27, 2020 (edited) Wait you need to set BIOS to OVMF and Machine to Q35. Edited April 27, 2020 by Carbongrip Quote Link to comment

I tried it with VNC it was on UEFI Shell window. SeaBIOS worked with VNC. I just tried both OVMF/SeaBIOS with Q35. Still no luck Quote Link to comment

Carbongrip Posted April 27, 2020 Share Posted April 27, 2020 Remove the vbios and boot without it. Its not a requirement and is optional. Quote Link to comment

bastl Posted April 28, 2020 Share Posted April 28, 2020 On 4/27/2020 at 5:52 AM, RickD00 said: I tried it with VNC it was on UEFI Shell window Type "exit" in the UEFI shell window and "continue" in the BIOS that opens. VM reboots and now you should see the the hint to "press any button to boot from the install media". Keep in mind this hint only shows a couple seconds and without pressing any button you will end in the UEFI shell again. Starting a VM and not quickly enough connecting with VNC you will miss this part. Also your boot order might be wrong. Post the xml of the VM. Quote Link to comment
