Do You Still Use R600g OpenCL Clover?

While the ROCm OpenCL code was recently open-sourced, that new Radeon OpenCL code only supports newer GPUs like Fiji and Polaris and experimental support for "GFX7" GPUs like Hawaii. Due to this newer OpenCL stack, AMD hasn't been investing in the "Clover" Gallium3D state tracker for providing OpenCL within Mesa. But there are at least some independent developers interested in still working on this older OpenCL code for previous Radeon GPUs, including pre-GCN hardware with R600g.

Trying Out MESA_NO_ERROR / KHR_no_error Support On Mesa 17.2-dev

Merged last month into Mesa Git and improved since then with follow-up commits has been KHR_no_error support for reducing the overhead of the OpenGL drivers by disabling certain error handling for OpenGL games/applications. This in turn can free up some CPU utilization and possibly lead to power-savings too.
