[Mesa-dev] [PATCH 00/15] radv: add support for VK_EXT_transform_feedback

[Samuel Pitoiset]

Hi,

This series implements VK_EXT_transform_feedback for RADV. We tested it
quite a lot with DXVK and also with RenderDoc, it should be stable enough.

Please review, thanks!

  nir: Add a pass for gathering transform feedback info

Samuel Pitoiset (14):
  vulkan: Update the XML and headers to 1.1.88
  nir: fix compacting varyings when XFB outputs are present
  radv: gather the number of streams used by geometry shaders
  radv: gather the number of output components per stream
  radv: gather which GS stream is used for every outputs
  radv: adjust the GSVS ring sizes based on the number of components
  radv: adjust the number of output components per stream
  radv: allow to use up to 4 GSVS ring buffers
  radv: allow to emit a vertex to a specified stream
  radv: gather stream output info
  radv: declare streamout SGPRs
  radv: emit stream outputs for vertex and tessellation stages
  radv: add multiple streams support for the GS copy shader
  radv: implement VK_EXT_transform_feedback
