Hey there beautiful people!
I've been trying to passthrough one of my GPU to install a KVM via vfio for a while now. I've followed some tutorials:
- https://www.youtube.com/watch?v=h7SG7ccjn-g&t=1233s (someordinarygamers tutorial)
- VFIO script and Permission Denied.
I figured out at some point that it is much much harder since I have two identical GPUs. I've managed to get everything in order up to the point where I regen my initramfs (mkinitcpio -p linux56) but when I reboot, it gives me the "sh /usr/bin/vfio-pci-override.sh Permission Denied" echo.
The thing is, I don't fully understand Haelikor's fix in VFIO script and Permission Denied. forum post. How do I append "pcie_acs_override=downstream,multifunction" to my boot? Also, will I have to manually shutdown the second iommu group at each boot?
I'd really like to keep both of those GPUs since the only other GPU I have would be a decent downgrade. I tried chmoding it with 777 to no avail. I have absolutely no problem starting from scratch again (already re-installed manjaro thrice XD what a noob am I right?) .
