2 Exact Same GPUs

[EclipzzeX]

I have 2 AMD RX580's (identical). Is it possible to have VFIO work?

hi @EclipzzeX, from what i remember, it will get very tricky as they will share the same IDs. the whole RX4xx and Rx5xx series are detected as the same cards, but not impossible!

So you will have to create custom scripts that run in initramfs at boot (in terms of distros using initramfs-tools, no idea how to set it up on dracut and mkinitcpio, maybe look into those systems documentation if that is what your distro uses?)

Wendell has a guide for setting it up on initramfs here

This is not something my script does right now due to the added complexity it adds (since i try to support initramfs, dracut and mkinitcpio) hence why i have the requirement of using different gpus based on different architectures.

maybe the script will handle it in the future, but i lack 2 identical gpus to test with so it will be kinda hard for me to verify that things actually work as i like to actually test things and confirm the test case properly 😅
