I could do with the help. Just need to know if I’m doing things right. As I’m very new to passthrough etc
AMD iGPU passthrough won't work
- Thread starter jhmc93
- Start date
Good evening, I was out on a journey on the last few days.
According to your lspci output the line "Kernel modules:" shows that you have to blacklist "snd_hda_intel" as well because the kernel want to use/load it via this driver module. So the last line has to look like
Then dont forget do execute "update-initramfs -u -k all" and reboot.
Sorry for the misunderstanding, yes you have to copy your "vbios_1002_1638.bin" to the file system path "/usr/share/kvm/" and add the filename (without path) in your guest-config after the "romfile=" parameter.

Hey Can do a spot check for me see if everything is right as i'm having amd crash issues on the driver, is that ok @VMler?
screenshots:
let me know if any mistakes.
thanks again for your help.
video=efifb:off does nothing on recent Proxmox versions. You are using ,x-vga=1 (Primary GPU) which is a NVidia GPU work-around and should not be used with AMD Radeon. args: -cpu 'host,-hypervision,kvm=off' is also a NVidia GPU work-around and should not be used with AMD Radeon. Don't bother with all the stuff about the radeon driver, since your GPU uses amdgpu only. In my experience AMD Windows drivers work better with machine version 7.2 than 8.1, try pc-q35-7.2 instead.EDIT: Sorry for wasting your time with this post.

if u look in previous posts. I was told use the args line and the other stuff. id prefer to keep my proxmox up to date. i just wanna know why radeon driver crashin in windows vm and also i have no image on my monitor
why u waste my time?, im just trying to pass through my gpu for my windows machine. but i get nothing but driver crashes etc.
i hope someone can rectify my issue, as ive been trying to get it to show on my monitor. but the driver on windows says its crashing. i don't know what to do at all
You could try pc-q35-7.2 instead of pc-q35-8.1 (as I suggested before and which has nothing to do with your Proxmox version). Proxmox fixates the machine version for Windows VM for a reason. I also can't help it that other people made some bad suggestion (for your particular hardware), but feel free to ignore me and I'll do the same (since I am just volunteering here).
To separate the Windows driver problems from the possible other passthrough problems: try booting your Windows VM with a Ubuntu Live installer ISO (don't install, just see if you get output on the physical display). If that does not work then there is something else that needs to be fixed first.

@leesteken it doesnt show when i try a Ubuntu live install, any help you could provide would be greatly appreciated.
The passthrough is not working yet and we need to fix this first.
Did you reboot Proxmox just before you tried? If not, can you try again after a reboot (and make sure no driver or VM touches the GPU before starting the VM).
What is the output of
cat /proc/cmdline on the Proxmox host?What is the output of
lspci -nnks 04:00 on the Proxmox host just before starting the VM.What does the current VM configuration file look like? Please copy&pase the contents (in CODE tags for readability) and not a screenshot.
@leesteken can you tell me your time zone. Because I’m busy atm and will have to send the info u requested in ur last reply at around 7-8pm uk time. As I’ll be free round then.
I'll get around to helping you when I get around to it. Sometimes I also help other people and I also do other things than volunteering here. When I see you posting new information, I'll try to help (but I sometimes also need time to research things). There is no need for you to hurry nor to wait for me, and other people can also join in with the helping.

Device 04:00 has a lot of functions but you are not using the pcie_acs_override. I would expect iGPU passthrough to crash your Proxmox when you start your VM. What do your IOMMU groups look like; what is the output of
for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done?args: -cpu 'host,-hypervisor,kvm=off' is a NVidia work-around and does not make sense for Radeon.Where did you get the ROM-files? Integrated GPU passthrough is much more troublesome than discrete GPUs and i am having trouble finding people who had success with a 5800H. Maybe you need to create your own GopDriver for 5800H? Unfortunately, I have no experience with that and cannot try it for myself.
EDIT: Please make sure Resizable BAR is disabled in the motherboard BIOS.

I followed the guide here:
https://github.com/isc30/ryzen-7000-series-proxmox,
What output do u want to see,
Where would that be located in resizable bar in the bios?
I don't know. Unfortunately, I have no experience myself with VBIOS patching.
I do want to see the IOMMU groups:
for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; doneI don't know your BIOS or have a manual. Please check for yourself. Sometimes it is called Smart Memory Access (SMA) or Clever Memory Access (CMA).
