[Mesa-dev] [PATCH 00/22] Gallium and R600 improvements

[Marek Olšák]

Hi everyone,

this series has two parts.

Patches 1-12 are Mesa/Gallium improvements. Most importantly, this adds acceleration of stencil copying (including glBlitFramebuffer) using the shader stencil export functionality. I am afraid r600g and radeonsi are the only drivers which can make use of it at the moment. There is also acceleration for depth texture mipmap generation.

Patches 13-22 are R600 improvements. There is a new derived state for the CB registers which kept cumulating in the draw_vbo function, and some improvements for depth-stencil flushing and uploading. My changes to the CB_TARGET_MASK emission in the compute code (patch #13) might need some review from somebody working on compute.

The R600 changes depend on the not-yet-committed patch "r600g: improve flushed depth texture handling v2" from Vadim Girlin.

The series fixes 23 depth-stencil piglit tests on r600g.
