Pascal, your system OpenCL library did not detect any capable GPU. Only your CPU is detected as an OpenCL device. However, darktable does not use it because our hand optimized CPU code is way faster.
If you expect something different, than it's probably the missing GPU. Most likely your system lacks the required drivers. Often you need two driver packages, one for the display driver and another one for the GPU-computing driver. But that's dependent on hardware.
