The app crashes on AMD iGPU
I have AMD Ryzen 7600X CPU with Raphael iGPU and RTX 4060 dGPU.
I want to make iGPU pass to guest OS while Linux host using NVIDIA GPU. But after select the IOMMU groups the app crashes and returns panic.
panic: runtime error: index out of range [0] with length 0
goroutine 1 [running]:

By the way, in the error log, the home directory is not same as mine. My /home is /home/kaan.
How can I solve that issue?
can you provide the output of debug.log?
Sure!

Seems like you are trying to setup passthrough for the igpu, this will not work from my knowledge.
a valid config (if the motherboard allows it) would be igpu for host and dgpu for the guest(VM).
I do however see where it is crashing and it is because you selected a card that has no vbios (since it is part of the cpu), so the crash actually stopped you from doing something you shouldn't. I will fix it and put in a warning.

So, it is impossible to pass iGPU to VM? Because my monitor connected to NVIDIA, and I have only 1 cable for my monitor.
i believe only intel supports passing through igpus and it is not well documented and the process is completely different to how you would pass through a pcie gpu which this is intended for, i should change the readme to reflect that since i didnt think people would try to passthrough an igpu to be honest.
amd has no support for it i believe.
and I have only 1 cable for my monitor.
look up "ghost display adapter" on amazon, get one (ideally displayport but hdmi works fine too) that is what i use when using https://looking-glass.io with the pcie gpu i passed through to the windows VM
But should be doable no? If iGPU is in IOMMU group alone (yes) Not bound to system (yes) Upgraded to CPU + iGPU with that in mind...

well, i unplugged my hdmi from dgpu to igpu and all IOMMU stuff works well. the problem is with igPU i guess.

you will need to get a ghost display adapter for your dgpu to work in the VM though and then you setup looking-glass and you will be good (or you can setup sunshine, both options will need a ghost adapter)
There is a sampledriver for a fake display that you can also use but it is not recommended as it does not give the same performance. :)
Closing as the issue was with trying to passthrough an igpu which is not supported. (and i have definitively not forgotten to close this earlier :joy: )
