From Wikipedia, the free encyclopedia
amdgpu is half of the device driver for AMD's GCN-based GPUs. There are two other "halfs" available, radeonsi, that is part of Mesa 3D and a proprietary half called AMDGPU-PRO. Originally the UMD radeonsi was written to work on top of the KMD radeon and AMDs proprietary UMD to work on top of fglrx.ko.
There is also RADV, which implements the Vulkan 1.0 specifications. RADV is strongly based on Intel's ANV driver but works on top of amdgpu (like radeonsi does, only that radeonsi implements OpenGL).[1]
