You can also pass through more than just a GPU. I pass through an NVMe disk and a USB controller, effectively giving me a full second computer within my workstation. It's honestly fantastic.
Ok. And I assume that’ll all work at PCI speeds making it much more performant than using virtio-based forwarding. Sounds neat. Do I need to do anything besides UEFI boot my virt-manager (QEMU) VM to make use of things like this?
I generally followed this guide, despite working from another distro:

The biggest pain every time I've done this is making sure that I can bind the device to the vfio driver.
