[Mesa-dev] [PATCH 00/13] R600 improvements

[Marek Olšák]

This series fixes 20 depth-stencil piglit tests on evergreen and enables ARB_blend_func_extended also on evergreen, so that evergreen support is on par with r700 in those areas. There's also a bunch of sampler view fixes and a couple of small optimization. Last but not least, samplers views are reworked to use r600_atom, which simplifies the code a bit.

For some reason, stencil texturing doesn't work on evergreen if I set the RADEON_SURF_SBUFFER flag with the stencil-only format S8_UINT. This looks like a bug in the surface allocator in libdrm. The workaround used here is not to set the flag.

Marek Olšák (13):
      r600g: fix all failing depth-stencil tests for evergreen
      gallium/util: add util_bit_last - finds the last bit set in a word
      r600g: don't call inval_shader_cache in r600_context_flush twice
      r600g: do fine-grained vertex buffer updates
      r600g: remove unused flag have_depth_fb
      r600g: consolidate code for setting sampler views and fix bugs in the process
      r600g: don't invalidate texture caches when setting sampler states
      r600g: consolidate and optimize sampler states changes for evergreen
      r600g: properly track which textures are depth
      r600g: only make constant buffers dirty if there's something to update
      r600g: convert sampler view emission into atoms
      r600g: remove unused code after conversion of sampler views
      r600g: fix lockups with and enable dual source blending on evergreen
