Nvidia 5000 series passthrough , failing miserably.

Good. I have no idea what that means but good for you

EDIT: I remember that the following is also required. Without "PCI-Express" it did not work for me. (The "primary gpu" maybe is not required but it works so I left it alone)

I use the pve kernel, and qemu, and my own modified minirootfs and kernel. I added some functionality that I needed to the kernel.

I solved it. It seems that the 5000 series needs

[device "ich9-pcie-port-1"]
  driver = "pcie-root-port"
  x-speed = "16"
  x-width = "32"
  multifunction = "on"
  bus = "pcie.0"
  addr = "1c.0"
  port = "1"
  chassis = "1"

What were the steps you did to add this code?

Adding a passthrough device from the PVE UI will automatically add this, since I'm using direct run qemu it doesn't add it.

PCI-Express seems to just check if the current machine type is q35..............
