Written by Michael Larabel in Intel on 26 October 2016 at 12:05 AM EDT. 12 Comments
Well known Intel open-source developer Ian Romanick has published a massive set of 59 patches for enabling GL_ARB_gpu_shader_int64 within core Mesa and their i965 DRI driver.

"Whew! Here it is! There are four main groups to this patch series," began Ian Romanick in announcing the patches for this big code addition to Mesa.

ARB_gpu_shader_int64 is about adding 64-bit integer support for OpenGL shaders, similar to ARB_gpu_shader_fp64 in bringing double-precision floating data point to shaders.

More details on the ARB_gpu_shader_int64 support can be found via this patch series. The INT64 Intel support is limited to Broadwell "Gen 8" hardware and newer.
