QEMU GPU-PCIe AmigaONE

@white

I didn't write such obvious things that the amigaone installation CD must contain the Silicon Motion driver.
It must.
If you want you can install from the ES2 installer or do it manually (drivers alone)

I'm very sorry but I don't have the skills to write detailed guides/HOWTO and I can't give you everything step by step.


qemu-system-x86_64 = QEMU PC System emulator
Try to run a "second ubuntu x86_64 iso" on your installed Ubuntu, but to benefit from vfio-pci.
Same vfio-pci data as you run qemu-system-ppc. Preferably without the "kvm" option (Kernel-based Virtual Machine)
You will find examples of how to do this everywhere. I don't want to paste the exact command line for you because I have no way of checking it at the moment.

The steps are basically the same.
What I get written in the qemu window for the sound is this after many checks:
Once I try to save Prefs/AHI/AC97 stereo++ etc. etc.

couldn't open play stream: Non-existent file or directory
sndio: failed to open device
audio: Could not create a backend for voice `via-ac97.out'

once the RadeonHD.chip are activated in kicklayout
the sound disappears

using the original ones from AHI and not those from ES 2.2

I have something like this and it works.




Still try this ubuntu via qemu X86_64 for peace of mind with GPU passthrough.
I can't think of anything else.

@white
Which audiodev backend are you using? What was the configure output for audio_drv_list? The errors don't make much sense as I don't think it should use sndio on Linux and I can't find the error before that that says "couldn't open play stream" in QEMU so no idea where that comes from but maybe it has something to do with you have to run QEMU as root for passthrough and maybe it can't connect to your sound server in that case? This may be different on every distro so I don't know what to do with that but may try using option. This is normally not recommended if you have a sound server and does not always work well but as a fall back it may work until you find out the issue.
