This topic is an attempt to gather results with VFIO passthrough on different motherboards and GPUs with QEMU for AmigaOS. If you managed to get it work please post:

motherboard, host CPU (model name from /proc/cpuinfo) and GPU type (lspci -vvnn output for the graphics card and its other functions like audio)
firmware settings you needed to change
host Linux version (distro version and uname -a output)
QEMU version and -machine option used
Link to benchmark results or if it was usable or not and what else you had to change such as INTERRUPT=no monitor file tool type or other symptoms you saw.

These infos may be in previous threads scattered around but it's hard to find and compare them and I won't go through all those threads to get them. So let's try to make one thread for this. To keep it organised please everybody make only one post (edit later if needed or add multiple results in same post if you tried more than one machine or GPU) and stay on topic so do not post anything else here just the data above.

Home away from home

Additional important info to be added from the guest OS:
Do you use INTERRUPT=Yes (default) or INTERRUPT=No (or NOINTERRUPT=Yes, which is the same, and was used in older versions instead but probably still is supported) in your DEVS:Monitors/Radeon icon ToolTypes?

Does anyone know if the QEMU vfio passthrough works with the SAM460 version machine version and the OS4.1FE for SAM?

Just can't stay away

What do you see when you close your eyes ?
I see light, lots of light
I see you, dad
And I see mommy too
And I see me and we are together
And we play forever.

@white
Please read first post and don't litter this thread with unrelated discussion. Only post results here so they are gathered at one place without distraction as currently these are all over the forum hidden in long threads. The intention of this thread was to get these at one place but there wasn't much interest.

Is there a moderator here who could remove unrelated posts from this thread please?
