Hi, I made sure that there is implementation of DFSG-free of OpenCL by Mesa 10. Mesa 10 is not installed in to Debian, this is no problem. And there are pocl as implementation DFSG-free using ocl-icd. This is packaging by ocl-icd maintainer. I will enable ocl library, and upload soon.
Thanks for your help and comment!
