Hi, I still get this when running darktable with mesa 17: [opencl_init] discarding device 0 `AMD REDWOOD (DRM 2.48.0 / 4.9.0-2-amd64, LLVM 4.0.0)' due to missing image support. Is it the driver that lack support for that functionality or is it rather a limitation of the device itself? My device is an "ATI Radeon HD 5670". Thanks, Antonio
