AMDGPU has been fully upstreamed, and integrates now in one kernel module the old Kernel Fusion Driver (KFD).<br>

AMDGPU also has an optional [[closed-source]] component, which operates on top of the open source AMDGPU for alternative [[3D graphics|3D]] application support, known as AMDGPU-PRO.<ref>{{cite web|url=http://www.pcworld.com/article/3075837/linux/amds-gaming-optimized-amdgpu-pro-driver-for-linux-is-in-beta.html|title=AMD's gaming-optimized AMDGPU-PRO driver for Linux is in beta|work=PCWorld|access-date=2016-07-25}}</ref>

AMDGPU-pro still distributed by AMD directly is reliably more up-to-date compared to kernels shipped in regular operating system distributions.
