  1. You will need to creat some files manualy.
  2. 1. Create vfio-pci-override.sh in /sbin with the following content:
  3.  
  4. #!/bin/sh
  5.  
  6. DEVS="0000:02:00.0 0000:02:00.1"
  7.  
  8. for DEV in $DEVS; do
  9.     echo "vfio-pci" > /sys/bus/pci/devices/$DEV/driver_override
  10. done
  11.  
  12. modprobe -i vfio-pci
  13. modprobe -i nvidia
  14.  
  15. 2. Create file vga_hook in /usr/share/initramfs-tools/hooks/ with the following content:
  16.  
  17. #!/bin/sh
  18. PREREQ=""
  19. prereqs()
  20. {
  21.      echo "$PREREQ"
  22. }
  23.  
  24. case $1 in
  25. prereqs)
  26.      prereqs
  27.      exit 0
  28.      ;;
  29. esac
  30. . /usr/share/initramfs-tools/hook-functions
  31. copy_exec /sbin/vfio-pci-override.sh /sbin
  32.  
  33. 3. Make both files executable:
  34.  
  35. $ sudo chmod +x /sbin/vfio-pci-override.sh
  36. $ sudo chmod +x /usr/share/initramfs-tools/hooks/vga_hook
  37.  
  38. 4. Add the following in modprobe.d/local.conf in place of the "options vfio-pci ids=xxx" line if present and remove the boot options from grub cmd line "vfio-pci.ids=10de:13c0,10de:0fbb".
  39.  
  40. install vfio-pci /sbin/vfio-pci-override-vga.sh
  41. install nvidia /sbin/vfio-pci-override-vga.sh
  42.  
  43. 5. Rebuild your initramfs:
  44.  
  45. $ sudo update-initramfs -u
  46.  
  47. 6. Reboot and proffit.
  48.  
  49. P.S. The line DEVS in vfio-pci-override.sh is for your current setup from the lspci -vnk you posted before. You can check for success of the update-initramfs by:
  50.  
  51. $ sudo lsinitramfs -l /boot/initrd.img-xxx |grep vfio-pci-override-vga.sh
