What are the HW requirements for OpenCL 2.0 in general, and for dynamic parallelism in particular? According to the spec, there are various levels of SVM that an OpenCL 2.0 conformant device may support, but dynamic parallelism is not an optional feature, but a must.
Will all GCN architecture IGPs and dGPUs support OpenCL 2.0? Or is there some limit?
AMD Unleashes World’s Most Powerful Server GPU for HPC new card based on Hawai should support OpenCL 2.0. IMHO it safe assume that all GCN 1.1 cards (R9 290X, R9 290, R7 260 and R7 260X will be supporting OpenCL 2.0. Most likely previous GCN 1.0 cards will support OpenCL 2.0 as well. But I don't except support in older VLIW based architecture.
