AMD GPU passthrough to VM for gaming

Cubes · January 14, 2023, 7:01pm

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)

Cubes · January 14, 2023, 7:14pm

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

Cubes · January 14, 2023, 7:57pm

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)

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

Cubes · January 15, 2023, 9:34am

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

neowutran · January 15, 2023, 9:44am

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

Cubes · January 15, 2023, 10:32am

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 ?

Cubes · January 15, 2023, 10:43am

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?

neowutran · January 15, 2023, 10:47am

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

mono · January 15, 2023, 10:51am

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.

Cubes · January 15, 2023, 10:55am

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?

Cubes · January 15, 2023, 10:57am

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?

neowutran · January 15, 2023, 11:20am

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

For better reactivity in games, I even suggest passthrough-ing a whole USB -controller- to the gaming qube.
Last I used USB -device- passthrough, I found some unacceptable lags for gaming. It was a few years back though, so YMMV !

Of course, your MoBo must have several USB controllers, but it’s usually the case (one on the CPU, one on the chipset). If unsure, some manufacturers have a “block diagram”.
If you don’t have several controllers on the MoBo, the alternative would be a PCIe-to-USB controller which you can then PT to the gaming qube.

Same remarks for audio, I found QEMU rather strange with noises and delay, but again, old tests so YMMV !

zithro · May 9, 2023, 12:28am

(Another remark, sorry for double posting but I forgot and didn’t want to edit, for users using mail).
When I’ve set up, I explicitely excluded the RX580 from the dom0 xorg.conf file, well, rather only included the non-gaming GPU in it like :

# GPU
Section "Device"
	Identifier  "Card1"
	Driver      "nouveau"
	BusID       "PCI:32:0:0"
EndSection

This way I can plug the RX580 in the primary/x16 slot.

PS: I’ve realized too late that you’re using a laptop, but it may be useful to desktop users. I’m not really a laptop user so other solutions may apply though.
