I suppose this would satisfy distribution requirements. Especially if we can merge all platforms to the same repo. It might be reasonable to optionally follow the model of OpenCL ICD (installable client drivers), when there is a frontend library moderating access to several backend libraries. Each driver can be built as a stand-along libopencl or as ICD, being picked up by frontend libopencl1. Modular ODP might well be just one of these drivers, serving the case when single platform combines different hardware instances. -- With best wishes Dmitry
