Help me boot into a PCI passthrough GPU (5700xt)

[TomiWebPro]

Error code:
swtpm_setup: Not overwriting existing state file.kvm: ../hw/pci/pci.c:1637: pci_irq_handler: Assertion `0 <= irq_num && irq_num < PCI_NUM_PINS' failed.stopping swtpm instance (pid 17041) due to QEMU startup errorTASK ERROR: start failed: QEMU exited with code 1

I am trying to pass through my 5700xt into my windows vm. I've set as much gpu passsthrough command as I can but when I try booting up the device it still says nope, the error code being above.

Any ideas how to solve this? Or do you know what the error code tells?

EDIT:

I've rebooted proxmox and have set my mechine as auto start, if I do that my graphics card is passed in definitely, but once I press restart vm or shutoff and restart my vm, the error code being above and I have to reboot my host mechine... I think it's related to some kind of driver issue or some sort in proxmox but this is just weird

Radeon 5700XT requires vendor-reset to reset properly and to be used more than once. Please search the forum for more information: https://forum.proxmox.com/search/64...t=post&c[child_nodes]=1&c[nodes][0]=16&o=date

HPNY!
I don't understand how to setup vendor reset, I didn't find an easy guide, can you explain the process clearer,
Thanks!

Maybe this old guide can get you started: https://www.nicksherlock.com/2020/11/working-around-the-amd-gpu-reset-bug-on-proxmox/
EDIT: And with newer kernels you also need to do this: https://github.com/gnif/vendor-reset/issues/46#issuecomment-992282166

Thanks for reply.

its not GPU ptoblem but NVME

proxmox kernel: vfio-pci 0000:02:00.0: Unable to change power state from D0 to D3hot, device inaccessible

02:00.0 is NVME passed to VM Win11

cant solve this ...

Maybe search for threads about NVMe passthrough (instead of and old duplicate thread about AMD GPU)? Work-around is to use disk passthrough instead of PCIe passthrough.

My solution, works back in january not so confident about it now but you can maybe try
