Need Help with Vulkan Setup

General system Newbie

I followed the steps on the arch wiki and installed all the necessary packages for vulkan to work on my AMD GPU.
when running “vulkaninfo” however; I get the following error message:

ERROR: [Loader Message] Code 0 : loader_scanned_icd_add: Driver /usr/lib/amdvlk64.so says it supports interface version 6 but still exports core entrypoints (Policy #LDP_DRIVER_6)

I’m fairly certain the problem isn’t compatibility since vulkan works just fine on Windows, so there must be something that went wrong during the installation process but I have no clue what it could be.

Vulkan on AMD is just installing vulkan-radeon and lib32-vulkan-radeon with sudo pacman -S vulkan-radeon lib32-vulkan-radeon given that a card new enough to have amdgpu support is present.

Did you reboot after installing those?

Whats the output of inxi -Gxxz?

I already did.

You are currently using the radeon - driver, which has no vulkan-support (the naming of the vulkan-radeon package is just not good, but vulkan-radeon requires amdgpu):

Make sure that amdgpu is installed with sudo pacman -S xf86-video-amdgpu
After that you need to enable amdgpu with the following wiki:
https://wiki.archlinux.org/title/AMDGPU#Enable_Southern_Islands_(SI)and_Sea_Islands(CIK)_support

You should also do a full update. The current kernel is 5.16.11 but you still run
