AMD GPU passthrough to VM for gaming

I have been trying passing through AMD RX 580 GPU to VM(debian 11) for gaming, I have read multiple GPU passthrough threads on here, but none that I found to answer my question.

My dom0 uses intel’s iGPU.

I have successfully passed the VGA PCI device to VM and started it, I followed this tutorial: Qubes OS article

in addition to that tutorial, I edited dom0’s grub config, adding to /etc/default/grub:

GRUB_CMDLINE_LINUX="... rd.qubes.hide_pci=01:00.0 amd_iommu=on"

then I did: sudo grub2-mkconfig -o /boot/grub2/grub.cfg

but when I start xorg script from that tutorial, I do not know what to do next, it does not open any windows using the GPU, all I see is this in terminal:

sudo ./xorgX1.sh /usr/bin/openbox

what am I missing? I do not know how to launch a program using the AMD GPU, it always launches them with software rendering instead.

can you post the result of the command “sudo dmesg” (launched from your gaming vm)

It was too long to post here, I’ve posted the result at: https://pastebin.com/raw/ydG98qEq

I noticed it sometimes showing “Obt-Message: Xinerama extension is not present on the server” after starting xorg server, which may be relevant, but I am not sure if it is. (I have only 1 monitor)

The interesting part is this one

add “pci=nomsi” to your grub boot param and retry ( resend the result of “sudo dmesg” and “cat /proc/cmdline”

This post was flagged by the community and is temporarily hidden.

Thank you for the reply. I added pci=nomsi to dom0’s grub.
executed on gaming VM:
sudo dmesg: https://pastebin.com/raw/Zt4AqAye
cat /proc/cmdline:

sorry, “pci=nomsi” in the guest grub boot param, not dom0

Added pci=nomsi to gaming VM’s grub.

The log look good now. You tried to launch xorg ?
What message do you get ? you have the screen connected to the rx 580 ready ?

Yes, I tried launching xorg, but nothing happens other than the usual text in the terminal. I have not connected rx 580 to monitor, I wasn’t sure if I have to, only iGPU is connected to monitor. I have a problem that if I connect both iGPU and rx580 to monitor, Qubes OS does not boot, only one at a time boots. Could it help to reinstall Qubes OS?

When you do this kind of passthrough (and want to display things), you need to have a monitor dedicated for this VM. So you need 2 monitor, or you can use a splitter if you don’t have/don’t want to have 2 monitor

Multimonitor would make things easier and he needs a video cable going out from that RX580 probably HDMI or display port ones going into a monitor.

Many Monitors have multiple inputs and he could switch to the other port via the Monitor Buttons.

Yes, I do have multiple inputs, but it does not seem to work when both are plugged into computer, I try to switch between them and it only goes back to the first screen, I am guessing it is caused by that during initial boot, with both plugged, it does not boot, so plugging it at runtime may not be accepted?

I noticed I get this in terminal on gaming VM when I plug in rx580 at runtime:

[../i3bar/src/xcb.c:1042] ERROR: PropertyNotify received for unknown window 00c00002

if I restart xorg server with rx580 plugged, I get this error:

I got it working! I had to change Modeline to a supported one in AOC.conf.

Only issue is my PS/2 keyboard does not seem to react in gaming VM, do I need a USB keyboard for the gaming VM?

Yes it is better, I usually pass a mouse and a keyboard in the VM
