OpenCL Image Support Worked Up For R600 Gallium3D

With Google Summer of Code 2015 now over, the reports are coming in from this year's X.Org GSoC projects.

Aside from the projects already covered in articles earlier this morning. another project marking completion was the OpenCL 1.1 image support for AMD's Radeon R600 Gallium3D driver.

Zoltan Gilian spent the summer hacking on OpenCL image support for R600 Gallium3D by implementing the needed image handling functions for OpenCL C v1.1. He managed to implement image attribute query, 2D image rendering, 2D image writing, and other functionality, but 3D image support didn't happen nor half-precision float formats.

The code has yet to be mainlined but for now is in branched versions of Mesa, LLVM, libclc, and the Piglit image tests. More details via Zoltan's blog.
