[SOLVED] QEMU PCI passthrough with only one GPU on PC

Hello. Sorry for my bad English smile
I read appropriate articles and sometime successfully used PCI passthrough with dual GPU - one for host and one for guest.
Now I have PC with only one GPU Radeon HD7850, without iGPU and I can't add second GPU.
I would like to start Arch Linux as host without graphics and QEMU machine with HD7850 passthrough. I think it is possible.
Host Arch Linux will be controlled over SSH and VNC (with xVNC, it is not require GPU).

Now I have a working configuration for dual GPU machine (likely. I can't verify that).
I look forward to your help in its minor correction for single GPU using.
Thanks in advance.

When I running PC i see a boot process of host OS. And that's bad. I understand that in working configuratgion the host OS can not allow anything output to monitor.
I blacklisted amdgpu and radeon modules:

# cat /etc/modules-load.d/blacklist.conf
blacklist amdgpu
blacklist radeon

Of course, I added fully IOMMU group to /etc/modprobe.d/vfio.conf

IOMMU Group 46 81:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Pitcairn PRO [Radeon HD 7850 / R7 265 / R9 270 1024SP] [1002:6819]

I know that you don't speak english well, but I still can't get what you mean with the above: are the modules you blacklisted still being loaded at boot, and so you see "output to monitor"?

If so, check the status of systemd-modules-load 

systemctl status systemd-modules-load

or try blacklisting your modules through /etc/modprobe.d (needs the "modconf" HOOK in mkinitcpio.conf).

Check these things first and then we'll see if qemu needs fixing, but most importantly feel free to report your own thread and ask a moderator if they can move your thread to Other Languages if you're not comfortable with english.

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

Modules is blacklisted and no loaded. Added amdkfd to blacklist.conf.

# cat /etc/modprobe.d/blacklist.conf 
blacklist radeon
blacklist amdgpu
blacklist amdkfd

lsmod shows that the modules "radeon", "amdkfd" and "amdgpu" are not loaded

Whlie booting, last what I see is "starting version 236" and picture on monitor "freezes".
But OS is fully working and I can connect via SSH.

When starting VM, monitor shows "no signal".

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

Maybe I know what's wrong: you're not supposed to blacklist your VGA modules. After all, the guest should rely on the host hardware (unless we're talking bridges and tun/tap interfaces) so by blacklisting the related modules you will prevent your VGA to be loaded.

So basically you should play a little more with how your kernel handles vfio and VGA passthrough. It seems too much complicated for me so I'll handle you the wiki page which will give you at least a good start if you've done something similar before.

It seems that UEFI is mandatory to accomplish your goal.

Have fun, start from that page and come back here if you need further assistance wink

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

lo1 I believe the blacklist is on the host with the devices being controlled by vfio instead intended for pass through to the client leaving the host with no GPU output.

Yeah I know, but anyway I'm thinking the kernel (the "real" linux kernel on the host machine) can interfere with vfio if the modules are blacklisted. Also, of course I had a quick glance at the wiki page I posted before and there's no mention of any blacklisting process.

Instead, as I understand one should pass the right kernel parameters and then rebuild the initramfs with every vfio options to achieve the PCI passthrough. https://wiki.archlinux.org/index.php/PC … ng_the_GPU

@loqs, correct me if I'm not getting this right. Are you more familiar with this?

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

Update:

echo 1 > /sys/bus/pci/devices/0000\:80\:02.0/remove

After this command absent any graphics output from host machine ("freezes" on BIOS post messages).
Really system is working.
But virtual machine still cannot started:

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

@lo1 no practical experience with this only theoretical.  If the modules are blacklisted they will not be loaded but that should not interefere with vfio,
if the modules are not blacklisted then making sure the devices are assigned to vfio before the other modules could be loaded is important
which is method the wiki is using from my understanding either way radeon etc should not be taking any part in controlling the hardware.

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

Wiki wrote:

While adding the kernel parameter intel_iommu=on is still needed for remapping IO (e.g. PCI passthrough with vfio-pci), -device intel-iommu should not be set if PCI PCI passthrough is required.

https://wiki.archlinux.org/index.php/QE … 29_support

Try deleting device intel-iommu from your qemu config file and see if it changes anything.

EDIT: try both with and without blacklisting, since we're still not getting if it is really required.

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

I would suggest disabling vga passthrough configuring a arch linux guest under qemu with sshd enabled so you can ssh into the guest with vga passthrough re enabled and see what hardware has been passed to the guest.

Re: [SOLVED] QEMU PCI passthrough with only one GPU on PC

I deleted device intel-iommu. Without blacklisting.
After that VM successfully started, but without video output to monitor ("NO SIGNAL")
HD7850 is detecting in Device Manager. Driver installed only from amd.com (not from Windows Update (error 31)).
All working after driver installed!
Now it remains to make the keyboard and mouse work and try to make Xorg work on the host machine without GPU, but that's another story. The most difficult has already been done smile
Thank you all very much!
