In this release, Beignet continue to improvement the quality, performance and debug support. In this release, Beignet add Broxton and Kabylake platforms support, and new llvm version support, includ llvm3.7 and llvm 3.8. In this release, Beignet enable debug info when output ASM and also add profiling support. Meanwhile, Beignet add more and more extensions and features, such as full cl_intel_subgroups extension, intel_accelerator and basic intel_motion_estimation and so on. The performance is also improved, especially for some algorithm, for example GEMM algorithm have about 2x gain.<o:p></o:p> <o:p> </o:p> The highlighted improvements are as below:<o:p></o:p> <o:p> </o:p> 1. 6th generation Intel Atom Processors (Broxton) support.<o:p></o:p> 2. 6th generation Intel Core Processors (Kabylake) support.<o:p></o:p> 3. LLVM 3.7 and 3.8 support.<o:p></o:p> 4. ASM debug infomation and profiling support.<o:p></o:p> 5. Experimental double data type support for processors after 6th generation(Broadwell) .<o:p></o:p> 6. Full cl_intel_subgroups extension.<o:p></o:p> 7. OpenCL 2.0 workgroup built-in functions.<o:p></o:p> 8. Local copy propagation optimization and other optimizations<o:p></o:p> 9. intel_accelerator extension and basic intel_motion_estimation extension.<o:p></o:p> 10. Android build.<o:p></o:p> 11. Refined printf implementation.<o:p></o:p> 12.
