Arch - Radeon RX 480
Sep 26, 2016
This short guide will get your shiny new RX 480 working on Arch Linux with the new AMDGPU driver stack.
Requirements
- Kernel 4.7 or higher (I prefer the linux-zen kernel for better desktop responsiveness and it’s in the repo)
- llvm svn
- mesa 12.1.0
Linux
Most, if not all, kernels available in the Arch repository are version 4.7 or higher. linux-zen can be installed for better desktop responsiveness.
llvm
llvm-svn has a user repository which means you will not need to compile it from source. Compiling from source can take hours and on my system it no longer successfully builds.

mesa
Search for mesa-git and install mesa-git, lib32-mesa-git, and opencl-mesa-git. This will require you to compile from source.
