[vfio-users] IO_PAGE_FAULT on dmesg

[LordZiru]

Thanks for your reply, Blank Field,
my vm does not crash, and the host work as usual, just a lot of
IO_PAGE_FAULT per secound.
yes, i'm passing through that device,

here is my startup script:
------------------------------------------------------------------------------------------------------------
sudo qemu-system-x86_64
-enable-kvm
-cpu host,kvm=off
-smp 2,sockets=1,cores=2,threads=1
-bios /usr/share/qemu/bios.bin
-m 4G -machine type=q35
-rtc base=localtime
-nodefaults
-nodefconfig
-nographic
-serial none
-parallel none
-balloon none
-monitor none
-display none
-readconfig  /home/qemu/config/lordziru.cfg
------------------------------------------------------------------------------------------------------------
[device "root.1"]
  driver = "ioh3420"
  bus = "pcie.0"
  addr = "1c.0"
  multifunction = "on"
  port = "1"
  chassis = "1"

[device "AMD-Radeon-HD-6450-Video"]
  driver = "vfio-pci"
  host = "04:00.0"
  bus = "root.1"
  addr = "00.0"
  multifunction = "on"
  x-vga = "on"
#  rombar = "0"
#  romfile = "/home/qemu/roms/Sapphire.HD6450.1024.121031.rom"

[device "AMD-Radeon-HD-6450-Sound"]
  driver = "vfio-pci"
  host = "04:00.1"
  bus = "root.1"
  addr = "00.1"

[device "Usb16.0"]
  driver = "vfio-pci"
  host = "00:16.0"
  bus = "root.1"
  addr = "16.0"
  multifunction = "on"

[device "Usb16.2"]
  driver = "vfio-pci"
  host = "00:16.2"
  bus = "root.1"
  addr = "16.2"

[drive "Drk1-LordZiru"]
  file = "/dev/Drk1/LordZiru"
  media = "disk"
  index = "0"
  cache = "none"
  format = "raw"
  aio = "native"
  if = "virtio"
------------------------------------------------------------------------------------------------------------
i start this with `cat /home/qemu/config/lordziru.txt` so i don't need to
put the "\" at the end of line to continue on the next line [Enter]
