[Mesa-dev] [PATCH 0/5] anv: Implement the depth PMA fix on Broadwell

This little series does a few little cleanups as well as implements the PMA
fix on Broadwell.  The cleanups are focussed around letting us not set
3DSTATE_WM_DEPTH_STENCIL::Depth/StencilBufferWriteEnable unless we
absolutely need to.  It turns out that Intel hardware makes early/late
depth test decisions based on these bits and enabling depth or stencil
writes when not needed can cause performance problems.

I also have patches for the Sky Lake stencil PMA fix but I'm seeing hangs
in Dota 2 so I won't send those out until we figure out why.

Jason Ekstrand (5):
  anv: Disable stencil writes when both write masks are zero
  genxml: Add the CACHE_MODE_1 register on gen8
  anv: Add support for the PMA fix on Broadwell
  anv/pipeline: Make a copy of VkPipelineDepthStencilStateCreateinfo
  anv/pipeline: Be smarter about depth/stencil state
