Linux PCI Pass Through

[MysticBenjii1]

So i'm relatively new to linux and i wan't to make a WIN10 VM via KVM. Right now i'm trying to pass through my RX 5700XT via OVMF and I've run the iommu groups command:

 

[ben@ben-pc ~]$ shopt -s nullglob
[ben@ben-pc ~]$ for g in /sys/kernel/iommu_groups/*; do
>     echo "IOMMU Group ${g##*/}:"
>     for d in $g/devices/*; do
>         echo -e "\t$(lspci -nns ${d##*/})"
>     done;
> done;#

 

But i have loads of groups with AMD all over the place and i'm wondering if ill have to ACS patch my kernel. IOMMU Group.txt

you're good.

IOMMU Group 19:
        0a:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] [1002:731f] (rev c1)

 

although for some reason the audio device hor hdmi/displayport audio isn't listed there.

 

what distro are you using and what version?

So i went through with isolating my GPU.

 

I added the new modules to the initramfs config and then regenerated the initramfs.

I then rebooted and i still got a signal from the GPU, as far as i'm aware you're not suppose to get a signal after isolating a GPU. 

 

So i'm a bit confusion at the moment.

that's odd.

 

if you run "lspci -nnv" without quotes in a terminal what does it display for the gpu?

you didn't do it correctly. if you did it would say kernel driver in use: vfio_pci but it doesn't.
