I'm trying to passthrough a gpu to a VM.
Set up:
Motherboard: Asus Z87-K
CPU: Intel Core i5 4670K
GPU: GTX 980/Tesla p100 16GB

/etc/default/grub:

# The IOMMU looks enabled
root@pve:~# dmesg | grep -e DMAR -e IOMMU
[ 0.054186] DMAR: IOMMU enabled

# but when trying to find the types no output is given
root@pve:~# find /sys/kernel/iommu_groups/ -type l
root@pve:~#

I started with https://pve.proxmox.com/wiki/PCI(e)_Passthrough. After that i've asked chatGPT and found this: https://medium.com/@aglubagerry/dev...rough-on-a-proxmox-hypervisor-vm-f3d060b28aef
but the one from medium didn't feel right but i've tryed it any way.
the output of atm is:

root@pve:~# cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-6.5.11-7-pve root=/dev/mapper/pve-root ro quiet intel_iommu=on iommu=pt pcie_acs_override=downstream,multifunction nofb nomodeset video=vesafb:eek:ff,efif:eek:ff
sorry i don't know how to not get the emojis :o = : o without the space
