7840HS - Can't passthrough - Inappropriate ioctl for device/failed to reset PCI device

[ragokan]

Hello, sadly I can't passthrough, so let me share my errors and configurations.

root@prox:~# qm start 110
error writing '1' to '/sys/bus/pci/devices/0000:c6:00.0/reset': Inappropriate ioctl for device
failed to reset PCI device '0000:c6:00.0', but trying to continue as not all devices need a reset

If I set "PCI device" to "primary" and set "Display" to "none", it sometimes says "cannot acquire lock" etc. After restarting, it says started but I can see that host ip never becomes available and I can't also do remote desktop or show it on monitor.

My configurations;

I tried Windows11, weirdly it said this PC does not support W11, so tried Windows 10. I installed drivers and I can see that drivers and device is there, but sadly when starting with monitor, it does not start :(

Try in bios turn on:

• IOMMU - its hidden or setup to AUTO, then change for ENABLED

• AIM-T (i think its amd similar iommu)

• SR-IOV

• SVM mode (Virtualization CPU - like AMD-V / VT-x)

• Extended Tag

• Extended Synch

• ASPM OFF <= OFF, but its power managment

I will check these in BIOS, thanks. It is too old but I will check :D

One step forward. Now I get it working, sadly after closing it, GPU or Ram something is not released. Config is;
I installed that script for GPU but I will try other stuff, too.
