Specifically, is Beignet OpenCL library supported? Any comment is appreciated.
Media Server Studio will include OpenCL 1.2 for GPUs in its next Linux "gold" release. Beignet may be an option until then but we have not validated this configuration.
This is a great news, specially, if it is implying that there would be an official support for OpenCL GPU under Linux as opposed to Beignet.
