Hello,
Recently I discovered a bug in the package "amd-opencl-icd".
After extensively testing Sid, Testing, and Stable (and Ubuntu; and
OpenSUSE) I can say with 100% of certainty that there is a problem with
the current "[b]amd-opencl-icd[/b]" packages in Sid/Testing and
Jessie-Backports.
In Jessie the default amd-opencl-icd package (v14.9) works fine and
correctly binds my CPU to OpenCL (AMD R9 270X). However, the backported
pacakge from sid (v15.7) doesn't. For some reason it doesn't bind my GPU
with OpenCL.

Here you can see that, with amd-opencl-icd (15.7), my processor is the
device binded to OpenCL. That's a problem.

Now, with the older amd-opencl-icd package installed (14.9), my GPU is
listed as the OpenCL Compute device. That's correct.
