[apparatus]

What’s the output of this command in dom0?

lspci -s 03:00.0 -k

[Zamm]

Hi,

Sorry for the delay, I just tried rebooting again and does show the change!
Would you still like me to execute the cmd provided?

[apparatus]

If it works then there is no need.

[Zamm]

Awesome so I attached it and attempted to start and got same error that I got when I was doing the sys-audio qube.

tart failed: internal error: Unable to reset PCI device 0000:03:00.0: internal error: Active 0000:03:00.1 devices on bus with 0000:03:00.0, not doing bus reset, see /var/log/libvirt/libxl/libxl-driver.log for details

So then tried both the permissive and no-restrict-reset options, however states that the VM is not running and doesn’t have the persistent flag, however can’t run VM due to error, vm is standalone and set to HVM.
I assume I would need to detach it from the current qubes o try the alternative option or to remove it from the other device shown which this option like with the audio wont be possible and the no-restrict-reset would then be the option?

[apparatus]

No idea what will work for you hardware, just try different options/combinations/etc.
If nothing will work then attach both devices to your gaming qube:

@solene

For what it’s worth, on my machine they are in the same IOMMU, I can’t assign one in a hvm without having the qube to fail starting.

[Zamm]

So you think if I attach the audio device considering they are together it should work?
Sorry for asking but if you could suggest the command I should use cause don’t wish to mess this part up.
I assume just qvm-pci attach {qube name} {device} --persistent for the audio or should I detach the GPU first and attach both with -o no-strict-reset argument.
The GPU is the Radeon RX 7800 TX but yea I understand due to the fact you don’t have the same hardware.
Yea just any advisory on the cmds I should execute to possible get this working would be great.

Thank you for all the asisstance regarding this. Ive learnt alot!

[apparatus]

Just add both of them in the Settings → Devices of your qube without no-strict-reset/permissive first.

[Zamm]

Hi thanks, again the obvious things I fail to realize.
However now that I am feeling better and good news to see that the adding the audio has solved the issue.

I will be honest in stating that I have never installed drivers for graphics card(atleast have not actively tried on linux) so I have no idea.
I was advised to install the xorg drivers for the GPU but I am not certain if that is some file I would need to find or if it is simply the Debian instructions given:

apt install xserver-xorg-input-kbd xserver-xorg-input-libinput xserver-xorg-input-mouse i3

But that is the drivers for the input and assume there are different ones needed for the GPU video rendering not present in the instructions.
I see mention of a favorite windows manager, so i would just assume using openbox would be good enough.(Will only be using debian, not a fan of arch)

Now the real issue for me is the config filewhich I assume is used to enable the ouput display on the second monitor for the standalone vm? My main concern being where do I keep the conf file(will I just keep it in the same folder where I keep the script and just execute the script whenever the system reboots?) and the other being the modeline as I am using one random tv for the second monitor and it states its important to get it right.
Regarding the BUS IDs for these files would I add both the GPUs and Audio device IDs? and I see in the example the nimber is different would I be correct to say that for the GPU
BusID “PCI:03:00.0” for conf file as the example is a bit different and not certain with the bash script what to leave out as in the example it is PCI:0:‘$pci’:0" how it should look for mine?

The amdgpu driver is already installed in debian-12-xfce template, no idea about other packages.

@Zamm

Now the real issue for me is the config filewhich I assume is used to enable the ouput display on the second monitor for the standalone vm? My main concern being where do I keep the conf file(will I just keep it in the same folder where I keep the script and just execute the script whenever the system reboots?)

The path to the config is specified in the script - /home/user/AOC.conf, you can put the file elsewhere but then you need to change the path in the script.

@Zamm

the other being the modeline as I am using one random tv for the second monitor and it states its important to get it right.

No idea about it. Try to generate it as stated here:

@taradiddles

# https://arachnoid.com/modelines/ . IMPORTANT TO GET RIGHT. MUST ADJUST WITH EACH SCREEN.

@Zamm

Regarding the BUS IDs for these files would I add both the GPUs and Audio device IDs? and I see in the example the nimber is different would I be correct to say that for the GPU
BusID “PCI:03:00.0” for conf file as the example is a bit different and not certain with the bash script what to leave out as in the example it is PCI:0:‘$pci’:0" how it should look for mine?

You don’t need to touch it, it’ll be replaced to the correct one automatically in the script.

[neowutran]

Updated the guide to integrate the work I have done with my automation script here ~yukikoo/gpu_template - Auto install a templateVM suitable for GPU passthrough, using the archlinux community template - sourcehut git
Manually settings Modelines should not be required.

[Zamm]

Awesome which will also mean I can use a Kicksecure morph without needing to think about installing drivers!
I just installed my windows manager and now is it me or has the /home/user/AOC.conf just been changed to /opt/xorg.conf ? and the file xorg.conf?

[Zamm]

Okay well looks like was edited but no worries change all the directories to the correct one in my case.
Note that the conf file was now changed in the and no longer includes modeline from what I can see and I adjusted the driver name to amdgpu as it instructs.
Currently the display for the GPU output is displaying the glitch issue with it just showing stuck on the startup for Qubes “Booting 'Qubes, with Xen Hypervisor, etc” and that it is all displaying as of current.
So script working and all, it update the ID for the GPU, etc but it is now displaying an output for the additional display:

Ultimately looks like an issue with the conf while or paritially due to it however not certain to the exact. Let me know if you would like me to post it for further investigation, will have a look at a bit myself to try and figure it out.

[apparatus]

Check that amdgpu driver is loaded:

lsmod | grep amdgpu

Check that amdgpu driver is used for your GPU:

lspci -s 07:00.0 -k

Check the sudo dmesg output and search errors related to your GPU.

Also try to use updated Xorg config and script.

[Zamm]

[user ~]% lsmod | grep amdgpu
zsh: done lsmod |
zsh: exit 1 grep --color=auto amdgpu

Second cmd gives no output.

Only see two errors:

Check if there drivers by trying to install:

sudo apt install xserver-xorg-video-amdgpu

and is already installed.

Tried pulling for output from dmesg that specifically mentions amdgpu and didn’t get anything.

Tried to manually load the drivers:

sudo: unable to resolve host Gaming: Name or service not known
modprobe: ERROR: could not insert ‘amdgpu’: Invalid argument
zsh: exit 1 sudo modprobe amdgpu

Second cmd gives no output.

Check the output of:

lspci -k

[23119.895331] out_of_memory+0xf4/0x320

How much memory did you assign to your qube? Did you disable memory balancing for it?

[Zamm]

12gb and memory balance is disable.

Try to use the original debian-12-xfce template without your custom modifications.
Rename your current debian-12-xfce template to debian-12-xfce-custom.
Install debian-12-xfce template from the Qubes OS repository and update it.
Install pciutils package in debian-12-xfce template.
Shutdown debian-12-xfce template.
Create an app qube with HVM virtualization, disabled memory balancing, initial memory set to 4096 MB, attach both 03:00.0 and 03:00.1 devices to it.
Start the app qube and check the output of this command to see if the amdgpu driver will be in use for your GPU:

sudo lspci -k

[apparatus]

Check the log in the qube to see if there are any errors related to your GPU or the amdgpu driver:

sudo journalctl -b > journal.log

Or upload the log here if you won’t be able to find it yourself.

Also try to install the newer firmware package for your GPU firmware-amd-graphics from the Debian backports in the template.
