That's a Sea Island generation GPU from AMD. amdgpu-pro does not support
Sea Island and its predecessor Southern Island. The latter affects my
HD7950 (Tahiti).
So what AMD currently does is:
* hard-deprecate the working Catalyst driver (fglrx): no longer
supported with recent kernels
* develop a new version of driver amdgpu-pro which is only
half-heartedly brought into all relevant distributions
* dump support for two complete generations of GPUs still heavily in use
That is simply disgraceful!
For my side it means that I can still live with fglrx as long as it is
supported by OpenSUSE. This support will end on May 16th 2017, which is
the announced end of life for Leap 42.1.
After this date I will likely invest into a new GPU. This will be an
NVIDIA and I will give up on AMD.
Concerning OpenCL support in darktable for AMD: from my side AMD will be
half-deprecated by then. Currently I run alongside the AMD and a seven
years old NVIDIA (fully supported by NVIDIA drivers from day one till
today) to have an eye on both platforms. In future I will focus all new
developments only on NVIDIA. AMD platforms might or might not work.
Issues will need to be fixed by those who are still keeping with AMD.
