Greetings,
I have a machine with an Intel igp of HD Graphics 610 [8086:5902].
I found several discussions on the subject stating that it isn't possible but
all of them are several years old.
so I wanted to know if it is possible to pass it to a vm?
I'm using kernel 5.4.43, libvirt-6.6.0 and

Greetings kram,
I think you need to extract the rom from the card. you can read Jeff Tchang's comment in this thread
btw, are you using GVT-g?

Greetings kram,
did it worked if you pass-though the gpu only, e.g. you see image but no sound?
if so, there is a patch floating around which will disable the iommu gorupings or something like that, it is a "breach of security" patch but it might do the trick.

Well, something isn't working now. I'm seeing this after loading the VM:
qemu-system-x86_64: vfio-pci: Cannot read device rom at :00:02.0
Device option ROM contents are probably invalid (check dmesg).
Skip option ROM probe with rombar=0, or load from file with romfile=

I can't think how a group with a single
Sure Alex, thanks for taking a look. Let me know if there's anything else
you want to see. It is a shell script and I get the same errors if I run
as user or root.
#!/bin/bash
qemu-system-x86_64 \
-enable-kvm \
-machine q35 \
-cpu host \
-nographic \
-vga none \
-device intel-iommu \
-device
I have not gotten the VM to boot, there is always the multiple address
spaces error. I don't think this is an ACS patch situation; the GPU sits
in it's own vfio group with no other devices.

Greetings Alex,
thanks for the info, I'll look into it.

Greetings Jeff.
intresting, can you share how it was performance wise?
I wonder about hte rom, it says that this rom can damage the screen if it has no prodection, how can I be sure it wrn't damage my tv?
in addition, the readme speaks of GVT-g, do one needs to use it? have you used it?

Excellent, it's working! Thanks Alex. I'm starting at the Kodi install
screen on the TV. I'm not sure about how the sound blacklisting is going
to affect when removed but this is working.
