# amdgpocl
OpenCL on amdgpu for Arch, also in the [AUR].
This package allows the usage of AMD's proprietary user-space OpenCL driver along with the free amdgpu stack. It should work with upstream amdgpu and Mesa. Inspired by [this blog post][gog].
## Hardware support
This *should* work with amdgpu-enabled GCN GPUs. Newer GPUs, starting with Vega (GCN Gen. 5+), support OpenCL via [PAL] and might work since commit [f5838ef] too, however I don't have the hardware to test it.
If you are using SI (Southern Islands, GCN Gen. 1) or CIK (Sea Islands, GCN Gen. 2), you'll need to enable the *amdgpu* and disable the *radeon* kernel module. Check the [Arch Wiki] for the exact steps.
Currently tested with Kernel 4.16 and Hawaii. Blender Cycles, Luxmark, F@H and ethminer seem to work without any problems.
## What this is not
You are not getting Vulkan support, faster 3D rendering or unicorns.
If you are looking for the full amdgpu-pro stack, including proprietary OpenGL and Vulkan implementations, move over to the [AUR][AUR-AMDGPU].
Expect maintenance of this package to be dropped when there is free OpenCL support on top of the [ROC] stack or the [PAL].
