qemu amigaos 4.1 sudo without no audio

I remembered correctly.
I swapped the GPU.
The login problem on both monitors is gone.
ACS is only enabled on the primary GPU.
In fact, the IOMMU groups are no longer separate.

Now I'm compiling:
linux-vfio for Arch-Linux

which has the ACS patches.

To see if it's convenient. Otherwise, I can always go back with the backup.

Too bad the motherboard supports ACS, but not fully.

Let's see if I can manage it.

I compiled Linux-Vfio for Arch and patched the kernel.

Everything works fine now.

The GPU are in the correct slots, the IOMMU groups are separated, and now I can even remove the HDMI audio from the R9 270x GPU using the QEMU command.
In short, ACS is in the TUF GAMING BIOS, but unfortunately, it has some limitations, so it can't be used for AmigaOS emulation in this case.

I'm happy now that I can log in to Linux directly on the primary monitor without any strange issues.

And then I can use the R9 270x on the second monitor completely normally, without the problems I had before.

I don't have to plug and unplug HDMI cables all the time.

Well,
Unbelievable!
Between audio not working and ACS on the motherboard, it was a real obstacle course for me.

I couldn't resist waiting for a refund on the HDMI KVM switch.
I ordered another, even cheaper one.

Now it works perfectly, but the problem wasn't the HDMI KVM switch.
But the command to assign the MOUSE directly in QEMU
like this:

I added a second mouse directly to the USB port on the PC I'm using.

Then:
sudo libinput list-devices:

Result:

Device: Logitech USB Optical Mouse
Kernel: /dev/input/event21
etc. etc.

sudo --preserve-env qemu-system-ppc -M amigaone -m 2048 -bios /home/white/Downloads/u-boot-amigaone.bin -serial stdio -drive media=disk,format=raw,file=/home/white/Downloads/Radeon/1ONE-32gb.raw -vga none -device vfio-pci,host=04:00.0,bus=pci.0,x-vga=on,multifunction=on -device bochs-display,romfile="" -accel tcg -device rtl8139,netdev=mynet0 -netdev user,id=mynet0 -object input-linux,id=mouse2,evdev=/dev/input/event21,grab_all=on,repeat=on
-device usb-mouse,id=mouse2


Now it's perfect I can use it A single monitor with the HDMI KVM switch.

There's no lag whatsoever with anything I use: the mouse, monitor, and everything else.

It's perfect.

Without hovering with:
-object input-linux,id=mouse2,evdev=/dev/input/event21,grab_all=on,repeat=on
-device usb-mouse,id=mouse2

This HDMI KVM switch also worked poorly with AmigaOS,
while it works flawlessly with PS5, for example.

I also remember that I now use linux-vfio for Arch in case it might be useful to others.
