Hello!
I try to passthrough GPU to the virtual machine (qemu). I've tried
different variants:
-device vfio-pci,host=02:00.0,bus=root.1,addr=00.0,multifunction=on,x-vga=on
or
-device vfio-pci,host=02:00.0,x-vga=on
and other but in any case I get error:
vfio 0000:02:00.0: failed getting region info for VGA region index 8:
Invalid argument
device does not support requested feature x-vga
dmesg contains:
[ 844.599821] vfio_ecap_init: 0000:02:00.0 hiding ecap 0x1e@0x258
[ 844.599860] vfio_ecap_init: 0000:02:00.0 hiding ecap 0x19@0x900
If I remove x-vga=on option then qemu works but there is no signal from
GPU (black screen).
It looks like http://vfio.blogspot.com/2014/08/vfiovga-faq.html
"Question 3:
I have Intel host graphics, when I start the VM I don't get any output
on the assigned VGA monitor... "
I've tried to use 2 versions of the kernel: 4.19 and 5.4 - no difference.
Moterboard: ASUS PRIME H370-A.
GPU: ASUS Turbo GeForce RTX 2060 Super.
What could be the cause of this problem?
Thanks!
