For your latter question, it doesn't seem like you should need to modify it as his original script already generically finds all GPUs. Did it not work when you tried it? Also, what type of cards are you using? If they're NVIDIA with nvidia drivers then I doubt that script will work for you. I'm using the following guide: https://vfio.blogspot.com/2015/05/vfio-gpu-how-to-series-part-3-host.html. I'm having trouble adapting some of the Fedora focused instructions for use in Arch.
*1. Dracut* Dracut isn't used in Arch but the mkinitcpio is. You're asked to insert *add_drivers+="vfio vfio_iommu_type1 vfio_pci vfio_virqfd" *in: */etc/dracut.conf.d/local.conf*. Farther down, I'm supposed to insert *install_items+="/sbin/vfio-pci-override-vga.sh /usr/bin/find /usr/bin/dirname" *in: */etc/dracut.conf.d/local.conf*. Should I instead add these lines to a modprobe.d conf file or should I add it to the modules line in */etc/mkinitcpio.conf*? *2. driver_override* My bash-foo isn't very good and I need to adapt the following script (see below) so that it points to the correct directories. In Arch, the directory for the GPU (02:00.0) and GPU audio (02:00.1) are here: */sys/devices/pci0000:00/0000:00:02.0/0000:02:00.0/* & */sys/devices/pci0000:00/0000:00:02.0/0000:02:00.1/* * #!/bin/sh DEVS="0000:02:00.0 0000:02:00.1" for DEV in $DEVS; do echo "vfio-pci" > /sys/bus/pci/devices/$DEV/driver_override done modprobe -i vfio-pci* Hope to hear from you soon!
