[SOLVED] Passthru of QAT on Intel 4xxx CPU

[Lurick]

I've tried following a few threads on here for passing through a QAT module:
https://forum.proxmox.com/threads/pve-blacklist-conf-not-working.134895/

But I can't seem to get it to show up in the passthru dropdown list no matter what I try.
The CPU in question has 2x QAT and is a Xeon Gold 5416S

I can see the QAT modules in lspci and other outputs but no matter what I've tried so far nothing shows up in the GUI for passthru.

:~# cat /etc/modprobe.d/vfio-pci.conf
options vfio-pci disable_denylist=1

lsmod | grep vfio
vfio_pci               16384  6
vfio_pci_core          86016  1 vfio_pci

If I missed anything let me know.

Above plus support being added should fix this
