I'm trying to get PCI-Passthrough, following the guide here:
Running Proxmox 6.1-7. Kernal version 5.3.18-2. Running a Ryzen 2600, on an ASRock B450M Pro4. Using a GTX 1070 and GT 710 as GPUs.

I have set the required parameter in /etc/default/grub, and added the modules in /etc/modules. Bios has IOMMU enabled.
The next step in the guide is to run dmesg | grep ecap. Which is supposed to tell me if my system supports or doesn't support interrupt mapping based on the last digit of the hex value, the issue is, I am getting no output whatsoever. I got an output two days ago, but many reinstalls later I no longer do. What could cause this, and how do I solve it?

It's not giving an output on the following BIOS versions, that I have tried: 3.90, 3.30, 3.10, 2.00

Any help is appreciated, thanks!

Did you enable the iommu in the BIOS?
