Hi,

I looked through many forums and tried many things but cant get this thing to work. I also tried different versions of nvidia game ready drivers.

Just a few comments, which probably won't fix your issue but can clean up your configuration a lot:

amd_iommu=on,iommu=pt,pcie_acs_override=downstream,multifunction is wrong: don't separate different kernel parameters with comma's. amd_iommu=on is never necessary (and not even valid) because it is on by default. Do you really need pcie_acs_override, as it has no effect because of the comma's. Therefore, you can replace all three wih just iommu=pt for setting up an identity mapping for non-passthrough devices on the host (which probably does nothing for your GPU passthrough).

Are you sure you are booting with GRUB? Check cat /proc/cmdline to make sure the parameters are passed to the kernel.

You don't need to blacklist radeon because you are passing through an NVidia GPU.

I cannot check whether 10de:1b81,10de:10f0 is correct from the information you gave. Maybe you can show 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, which will also check your IOMMU groups. Those ids are not really necessary if you are blacklisting all the drivers anyway, but otherwise you have to make sure the vfio-pci module is loaed before the actual drivers.

You can probably remove args: -cpu 'host,-hypervisor,+kvm_pv_unhalt,+kvm_pv_eoi,hv_spinlocks=0x1fff,hv_vapic,hv_time,hv_reset,hv_vpindex,hv_runtime,hv_relaxed,kvm=off,hv_vendor_id=amd' and just add x-vga=1 to the hostpci0 line: hostpci0: 0000:06:00,pcie=1,x-vga=1. Do you really need ,hidden=1,flags=+pcid,hv-vendor-id=proxmox added to the cpu line, because you override it with the args line anyway? Again, using x-vga=1 already takes care of this for NVidia cards.

Maybe just using the Primary GPU option (x-vga=1) intended for this instead of all the overrides works better for your GPU passthrough?
 
thanks for the reply!

I ran "cat /proc/cmdline" and got the following:
Code: 
root@pve:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-5.11.22-5-pve root=/dev/mapper/pve-root ro quiet amd_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb nomodeset video=vesafb:off video=efifb:off textonly video=astdrmfb

I ran "for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done" and got the following:

my gpu has the following line : IOMMU group 20 06:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP104 [GeForce GTX 1070] [10de:1b81] (rev a1)

as for your other suggestions about removing code and editing some of my codes, it has been applied.
 
You can remove amd_iommu=on because it does nothing (and is invalid), pcie_acs_override=downstream,multifunction because you don't need it (it would not help if you did need it and it invalidates all the grouping information you showed) and video=astdrmfb because your don't have a AST2000 onboard a B450 or X470 motherboard.

You passthrough is working in principle but your GPU does not reset in a way that the Windows driver expect and/or can handle. Did you run a update-initramfs -u (before proxmox-boot-tool refresh) to make sure the options from the files in /etc/modprobe.d/ are applied?
 
I ran update-initramfs -u and got the following:
Code: 
root@pve:~# update-initramfs -u
update-initramfs: Generating /boot/initrd.img-5.11.22-5-pve
Running hook script 'zz-proxmox-boot'..
Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace..
No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync.

I kind of found a solution when you said You passthrough is working in principle but your GPU does not reset in a way that the Windows driver expect and/or can handle I made a new windows 10 VM and refollowed the instructions to enable passthrough and it worked, I'm not sure how or why though. The only thing that I can thing of that could have broke it was using a powershell script to debloat the machine.
