pci-device
There are 3 repositories under pci-device topic.
ipaqmaster/vfio
A script for easy pci and usb passthrough along with disks, iso's and other useful flags for quick tinkering with less of a headache. I use it for VM gaming and other PCI/LiveCD/PXE/VM/RawImage testing given the script's accessibility.
mr2527/pop_OS-win10-KVM-setup
This is a repo that contains directions and the necessary files to create a working pop!_OS -> Windows 10 KVM that has GPU Passthrough, CPU Passthrough with proper pinning, Allocated ram, and PCIe passthrough with QEMU and Virt-Manager.
KernelWanderers/PDP
PDP (PCI Device Paths) is an application meant to find all the PCI devices associated and display their appropriate PCI paths (conforming to OpenCore's convention), if possible.
