rachid596 Posted January 21, 2022 Share Posted January 21, 2022 With my rtx 3070 i can passthrough Only if my unraid boot on legacy mode not uefi Quote Link to comment
binaryhamster Posted January 21, 2022 Author Share Posted January 21, 2022 I am on legacy... changed it....I just unmark the "Force UEFI"... Thats enough right? Or I need to reinstall flash with legacy? Quote Link to comment

You didn't setup correctly the passthrough. Why you didn't attach diagnostics? How one can know what it is that device? Anyway, 08:00.4 is in a iommu group together with other devices, that are not attached to vfio, so 08:00.4 can't be resetted. Quote Link to comment

ghost82 Posted January 21, 2022 Share Posted January 21, 2022 This: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </source> <rom file='/mnt/disk3/VM-shared/System/rtx3700.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x4'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x1'/> </hostdev> is wrong. you are passing the video part of the gpu, putting it in a multifunction device at 00:05.0 and then you are passing the analogic built in audio and assign it to the multifunction device. 1. Replace this: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </source> <rom file='/mnt/disk3/VM-shared/System/rtx3700.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x4'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x1'/> </hostdev> with this: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/> </source> <rom file='/mnt/disk3/VM-shared/System/rtx3700.rom'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0' multifunction='on'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x06' slot='0x00' function='0x1'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x1'/> </hostdev> <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x4'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> This will pass both digital and analogic audio. If you use displayport or hdmi audio only you can delete this part: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x4'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> 2. You should attach to vfio at boot iommu groups 15 and 20: note: you won't have video output for unraid, the system will seem frozen, but it's not, connect to the unraid gui from an external device in the lan. 3. Ensure that rtx3700.rom is compatible with your gpu; if you are unsure, dump it from your card, if it's already dumped from your gpu you are ok. 4. reboot unraid and try. If it doesn't work attach new diagnostics with all these changes applied. Quote Link to comment

ghost82 Posted January 21, 2022 Share Posted January 21, 2022 Try to remove this: <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x4'/> </source> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </hostdev> Quote Link to comment
binaryhamster Posted January 21, 2022 Author Share Posted January 21, 2022 Same result. Do I need to wait for the VM to fully boot before I try and take HDMI out and in? Quote Link to comment

ghost82 Posted January 21, 2022 Share Posted January 21, 2022 No idea..nothing in the logs as far as I can see. I would try to switch to pc-q35 machine type instead of i440fx and reapply all the fixes. Maybe you can run it first with vnc/emulated graphics, once booted you can enable remote desktop, check that it works with an external device, switch to gpu passthrough; if the vm boots but has no video output you can connect to it with remote desktop and check if the gpu is detected in windows but throws errors or if it's not detected at all. If it's detected with errors, maybe you need to install drivers to have a display output. 1 Quote Link to comment
binaryhamster Posted January 21, 2022 Author Share Posted January 21, 2022 I can connect to the vm while its in passthrough? How? The choise dissapears when I put it in passthrough Quote Link to comment
ghost82 Posted January 21, 2022 Share Posted January 21, 2022 From an external device, with remote desktop because you will enable it inside the vm. Quote Link to comment
binaryhamster Posted January 21, 2022 Author Share Posted January 21, 2022 Nice...Good thinking... I will try Quote Link to comment
binaryhamster Posted January 21, 2022 Author Share Posted January 21, 2022 You are a bloddy genius... I installed Teamviewer because thats the only one I knew for windows. Then I just installed the nvidia drivers and boom...It appeared. Ive been obsessed about this issue for 3 days now. I bought the 2000$ setup just for this purpose and the thought of not being able because of bad choise of hardware would have been devastating. Thanx again man... Your awsome... Next step...passthrough keyboard and mouse. 2 Quote Link to comment

Been trying all sorts of "fixes" but no luck. Did you changed the to q35 or left it as i440fx? Quote Link to comment
