Hello again again [😊]
Noticed that when i do vfio-bind for the gpu it works, but then when i do it
for the audio it does not work it ends up in D+. This is the script:
#!/bin/bash
modprobe vfio-pci
for dev in "$@"; do
vendor=$(cat /sys/bus/pci/devices/$dev/vendor)
device=$(cat /sys/bus/pci/devices/$dev/device)
if [ -e /sys/bus/pci/devices/$dev/driver ]; then
echo $dev > /sys/bus/pci/devices/$dev/driver/unbind
fi
echo $vendor $device > /sys/bus/pci/drivers/vfio-pci/new_id
done
Best regards zChris
ps. i hope i dont annoy you too much

Hello again,
It seems that X just dies and i cant switch to a TTY console when i have
vfio-pci.ids=gfxcard in the boot cmdline. Also dmesg | grep -i vgaarb gives
this:

Is it a problem that vgaarb adds the gfx before vfio does?

Subject: [vfio-users] Blank output on passed card. i915 host gtx1060 vm
Hello,
Ive been trying to get pci passthrough going for a couple of days now to no
success. All i get when i start the vm is a blank screen on the vm and a
console on the host.
Ive been reading these guides:
https://wiki.archlinux.org/index.php/PCI_passthrough_via_OVMF and
https://wiki.installgentoo.com/index.php/PCI_passthrough .
My setup is as follow:
MSI B75M DGS R2 ( http://www.asrock.com/mb/Intel/B75M-DGS%20R2.0/ )
GTX 1060 not sure of vendor.
Im using 1 monitor, dvi connected to GTX1060 and VGA from built in vga output
on the motherboard.
dmesg | grep -i iommu gives:

Which tells me that it got binded to vfio ok.

intel_iommu=on vfio-pci.ids=10de:1c03,10de:10f1 i915.enable_hd_vgaarb=1
where i bind the GPU and HDMI AUDIO and enable vgaarbfor i915.
Now i try to start QEMU with:
qemu-system-x86_64 -enable-kvm -m 1024 -cpu host,kvm=off \
-smp 2,sockets=1,cores=2,threads=1 \
-device vfio-pci,host=01:00.0,multifunction=on \
-device vfio-pci,host=01:00.1 \
-drive if=pflash,format=raw,readonly,file=/usr/share/OVMF/OVMF_CODE.fd \
-drive if=pflash,format=raw,file=/usr/share/OVMF/OVMF_VARS.fd \
-vga none
when i switch over to the other input it just says no signal and swithes back.
And now i have no idea what to do.
Best regards zChris
